Why do organisations still struggle to protect our data? We asked 50 professionals on the privacy front line

<a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> More of our personal data is now collected and stored online than ever before in history. The rise of data breaches should unsettle us all. At an individual level, data breaches can compromise our privacy, cause harm to our finances and mental health, and even enable identity theft. For organisations, the repercussions can be equally severe, often resulting in major financial losses and brand damage. Despite the increasing importance of protecting our personal information, doing so remains fraught with challenges. As part of a <a href="http://www.doi.org/10.25910/psq3-q365">comprehensive study</a> of data breach notification practices, we interviewed 50 senior personnel working in information security and privacy. Here’s what they told us about the multifaceted challenges they face. <h2>What does the law actually say?</h2> Data breaches occur whenever personal information is accessed or disclosed without authorisation, or even lost altogether. <a href="https://www.abc.net.au/news/2024-06-20/optus-hack/104002682">Optus</a>, <a href="https://www.abc.net.au/news/2022-11-09/medibank-data-release-dark-web-hackers/101632088">Medibank</a> and <a href="https://www.afr.com/technology/canva-criticised-after-data-breach-exposed-139m-user-details-20190526-p51r8i">Canva</a> have all experienced high-profile incidents in recent years. Under Australia’s <a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/">privacy laws</a>, organisations aren’t allowed to sweep major cyber attacks under the rug. They have to notify both the regulator – the Office of the Australian Information Commissioner (OAIC) – and any affected individuals of breaches that are likely to result in “<a href="https://www8.austlii.edu.au/cgi-bin/viewdb/au/legis/cth/consol_act/pa1988108/#:%7E:text=Whether%20access%20or%20disclosure%20would%20be%20likely%2C%20or%20would%20not%20be%20likely%2C%20to%20result%20in%20serious%20harm%2D%2Drelevant%20matters%20%C2%A0">serious harm</a>”. But according to the organisational leaders we interviewed, this poses a tricky question. How do you define serious harm? Interpretations of what “serious harm” actually means – and how likely it is to occur – vary significantly. This inconsistency can make it impossible to predict the specific impact of a data breach on an individual. Victims of domestic violence, for example, may be at increased risk when personal information is exposed, creating harms that are difficult to foresee or mitigate. <h2>Enforcing the rules</h2> Interviewees also had concerns about how well the regulator could provide guidance and enforce data protection measures. Many expressed a belief the OAIC is underfunded and lacks the authority to impose and enforce fines properly. The consensus was that the challenge of protecting our data has now outgrown the power and resources of the regulator. As one chief information security officer at a publicly listed company put it: <blockquote> What’s the point of having speeding signs and cameras if you don’t give anyone a ticket? </blockquote> A lack of enforcement can undermine the incentive for organisations to invest in robust data protection. <h2>Only the tip of the iceberg</h2> Data breaches are also underreported, particularly in the corporate sector. One senior cybersecurity consultant from a major multinational company told us there is a strong incentive for companies to minimise or cover up breaches, to avoid embarrassment. This culture means many breaches that should be reported simply aren’t. One senior public servant estimated only about 10% of reportable breaches end up actually being disclosed. Without this basic transparency, the regulator and affected individuals can’t take necessary steps to protect themselves. <h2>Third-party breaches</h2> Sometimes, when we give our personal information to one organisation, it can end up in the hands of another one we might not expect. This is because key tasks – especially managing databases – are often outsourced to third parties. Outsourcing tasks might be a more efficient option for an organisation, but it can make protecting personal data even more complicated. Interviewees told us breaches were more likely when engaging third-party providers, because it limited the control they had over security measures. Between July and December 2023 in Australia, there was an increase of <a href="https://www.oaic.gov.au/privacy/notifiable-data-breaches/notifiable-data-breaches-publications/notifiable-data-breaches-report-july-to-december-2023">more than 300%</a> in third-party data breaches compared to the six months prior. There have been some highly publicised examples. In May this year, many Clubs NSW customers had their personal information potentially <a href="https://www.rimpa.com.au/resource/more-than-a-million-australian-data-records-potentially-exposed-in-nsw-club-and-pub-data-breach.html#:%7E:text=Outabox%2C%20the%20IT%20services%20provider,and%20has%20notified%20law%20enforcement">breached</a> through an attack on third-party software provider Outabox. Bunnings suffered a <a href="https://australiancybersecuritymagazine.com.au/bunnings-customer-data-compromised/">similar breach</a> in late 2021, via an attack on scheduling software provider FlexBooker. <h2>Getting the basics right</h2> Some organisations are still struggling with the basics. Our research found many data breaches occur because outdated or “legacy” data systems are still in use. These systems are old or inactive databases, often containing huge amounts of personal information about all the individuals who’ve previously interacted with them. Organisations tend to hold onto personal data longer than is legally required. This can come down to confusion about data-retention requirements, but also the high cost and complexity of safely decommissioning old systems. One chief privacy officer of a large financial services institution told us: <blockquote> In an organisation like ours where we have over 2,000 legacy systems […] the systems don’t speak to each other. They don’t come with big red delete buttons. </blockquote> Other interviewees flagged that risky data testing practices are widespread. Software developers and tech teams often use “production data” – real customer data – to test new products. This is often quicker and cheaper than creating test datasets. However, this practice exposes real customer information to insecure testing environments, making it more vulnerable. A senior cybersecurity specialist told us: <blockquote> I’ve seen it so much in every industry […] It’s literally live, real information going into systems that are not live and real and have low security. </blockquote> <h2>What needs to be done?</h2> Drawing insights from professionals at the coalface, our study highlights just how complex data protection has become in Australia, and how quickly the landscape is evolving. Addressing these issues will require a multi-pronged approach, including clearer legislative guidelines, better enforcement, greater transparency and robust security practices for the use of third-party providers. As the digital world continues to evolve, so too must our strategies for protecting ourselves and our data.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/236681/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jane-andrew-10314">Jane Andrew</a>, Professor, Head of the Discipline of Accounting, Governance and Regulation, University of Sydney Business School, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dr-penelope-bowyer-pont-1550191">Dr Penelope Bowyer-Pont</a>, Researcher, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/max-baker-25553">Max Baker</a>, Associate professor, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Who dies in a heat wave? How to help protect the vulnerable in our communities

<a href="https://theconversation.com/profiles/myles-david-sergeant-1542267">Myles David Sergeant</a>, <a href="https://theconversation.com/institutions/mcmaster-university-930">McMaster University</a> Extreme heat is a silent killer. From time to time, we hear about shocking cases of <a href="https://www.theguardian.com/world/2023/sep/24/football-player-heat-deaths-athlete">football players</a> and other athletes who die suddenly while exerting themselves on hot days. Those deaths are certainly tragic, but statistically they are very rare. Most deaths from extreme heat <a href="https://www.epa.gov/climate-indicators/climate-change-indicators-heat-related-deaths">are in older people</a>, who frequently die alone inside their homes. They often die slowly, as the heat creeps up to and sometimes past body temperature, especially when heat domes park themselves over cities and keep the temperature high all day and all night. When such deaths happen, they rarely make the news. Of all the climate change disasters our world is already experiencing, heat is the top killer, <a href="https://library.wmo.int/viewer/68500/download?file=1335_WMO-Climate-services-Health_en.pdf&type=pdf&navigator=1">as the World Meteorological Organization reported</a>. The planet was more than <a href="https://www.theguardian.com/environment/article/2024/jul/08/temperatures-1-point-5c-above-pre-industrial-era-average-for-12-months-data-shows">1.5 C above the pre-industrial baseline</a> for 12 consecutive months from July 2023 to June 2024. In July this year, we saw the hottest three days ever on record, prompting <a href="https://www.un.org/sg/en/content/sg/press-encounter/2024-07-25/secretary-generals-press-conference-extreme-heat">a special statement from United Nations Secretary-General Antonio Guterres</a>. <h2>Health risks and heat</h2> <a href="https://www.ncbi.nlm.nih.gov/books/NBK499843/">Our bodies are made to dump excess heat</a> when we are too warm, but that process goes into reverse when the air is warmer than our core temperature. Our other main defence, sweating, doesn’t help when humidity saturates the air, making it impossible for our own moisture to evaporate. For the frail and elderly, who are more likely to be labouring with heart troubles, COPD or other challenges, simply sitting still in a heat wave requires an effort equivalent to walking on a treadmill. The effort is not great, but it is <a href="https://doi.org/10.1016/j.cjco.2021.10.002">steady and relentless</a>. It exhausts the body, sometimes to the <a href="https://doi.org/10.1016/S2542-5196(22)00117-6">point of no return</a>. Tracking heat-related deaths is challenging, and it’s changing as authorities become more aware of heat as a contributing or underlying factor to deaths by other causes. <a href="https://doi.org/10.2105/AJPH.2006.100081">A paper published by the American Journal of Public Health</a> points out that the 1995 heat wave in Chicago likely contributed to hundreds more deaths than had first been attributed to heat itself. <h2>Who is at risk?</h2> Many people lack air conditioning or a way to get to a place that has it, such as a library, recreation centre or shopping mall. As a result, too many people in cities are forced to <a href="https://wmo.int/publication-series/2023-state-of-climate-services-health">endure long waves of heat</a> — waves that are occurring more frequently, lasting longer, and reaching higher temperatures — in a trend that appears set to continue getting worse. Air conditioning, <a href="https://www.lpm.org/news/2015-07-24/the-history-of-movie-theaters-and-air-conditioning-that-keeps-film-lovers-cool">once a luxury that drew people to summertime movie theatres on hot nights</a>, has become a necessity. Increasingly, it is also a legal requirement, as cities pass bylaws requiring landlords not to allow the temperature in their tenants’ quarters to rise above a certain level. Toronto has <a href="https://www.toronto.ca/home/311-toronto-at-your-service/find-service-information/article/?kb=kA06g000001xvbiCAA">such a bylaw</a> for rental units that have air conditioning available, capping indoor temps at 26 C between June 2 and Sept. 14. Such laws recognize the vulnerability of tenants who lack control over the temperature in their rental units, making heat death an especially urban tragedy, as confirmed in <a href="https://www150.statcan.gc.ca/n1/en/pub/82-003-x/2024006/article/00001-eng.pdf?st=e6jLNMuq">a recent Statistics Canada study</a> between 2000 and 2020. Deaths from extreme heat were more likely in cities with a higher percentage of renter households. During a single week-long heat wave in June 2021 — the year after the period captured in the Statistics Canada study — <a href="https://www.cbc.ca/news/canada/british-columbia/bc-heat-dome-sudden-deaths-570-1.6122316">B.C.’s chief coroner found that 570 people died from heat-related causes</a> — 79 per cent of them were seniors. <h2>Taking action at the community level</h2> From this Global North perspective, the community members who are most likely to die from extreme heat included: <ul> <li>Those over 65</li> <li>Those with more than one chronic condition (including hypertension, mental health, diabetes, heart disease, lung disease)</li> <li>Socially disadvantaged populations in our communities</li> <li>Those with mobility issues</li> <li>Those experiencing social isolation (living alone)</li> <li>Tenants with lack of air conditioning</li> <li>Those living in an urban heat island</li> </ul> This problem is not going away. Some of the <a href="https://www.intactcentreclimateadaptation.ca/wp-content/uploads/2022/06/UoW_ICCA_2022_04-Irreversible-Extreme-Heat.pdf">actions we can take</a> to protect our most vulnerable community members include: <ul> <li>Increase awareness that excessive heat is not merely uncomfortable, but dangerous.</li> <li>Make sure people are warned about impending heat waves.</li> <li>Advocate for everyone to have access to air conditioning.</li> <li>Check on and support people who live alone, especially those with no air conditioning.</li> <li>Invite people over if you have air conditioning, or help them get to community cooling stations.</li> <li>Help vulnerable people who do not have air conditioning to improvise, by freezing wet cloths, for example, to take out and hang around their necks.

How do heat protectants for hair work? A chemistry expert explains

<a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Heat can do amazing things to change your hairstyle. Whether you’re using a curling wand to get ringlets, a flat iron to straighten or a hair dryer to style, it’s primarily the heat from these tools that delivers results. This comes with casualties. While your hair is surprisingly tolerant to heat compared with many other parts of your body, it can still only withstand so much. Heat treatment hair appliances frequently operate at over 150°C, with some reportedly <a href="https://www.frontiersin.org/journals/bioengineering-and-biotechnology/articles/10.3389/fbioe.2019.00298/full#B13">reaching</a> <a href="https://www.researchgate.net/publication/289291195_Thermal_degradation_of_hair_I_Effect_of_curling_irons">over 200°C</a>. At these temperatures, your hair can end up fried. Many people use heat protectants, often in the form of sprays, to minimise the damage. So how do these protectants work? To answer that, I first have to explain exactly what heat does to your tresses on the molecular level. <h2>What heat does to your hair</h2> A large proportion of your hair is made up of proteins. There are attractive forces between these proteins, known as hydrogen bonds. These bonds play a big role in dictating the shape of your locks. When you heat up your hair, the total attraction of these hydrogen bonds become weaker, allowing you to more easily re-shape your hair. Then, when it cools back down, these attractions between the proteins are re-established, helping your hair hold its new look until the proteins rediscover their normal structure. The cuticle – the outermost protective layer of your hair – contains overlapping layers of cells that lose integrity when they’re heated, damaging this outer protective layer. Inside that outer layer is the cortex, which is rich in a protein called keratin. Many proteins don’t <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">hold up structurally</a> after intense heating. Think of cooking an egg – the change you see is a result of the heat altering the proteins in that egg, unravelling them into different shapes and sizes. It’s a <a href="https://library.scconline.org/v049n04/33">similar story</a> when it comes to heating your hair. The proteins in your hair are also susceptible to heat damage, reducing the overall strength and integrity of the hair. Heat can also affect substances called melanin and <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">tryptophan</a> in your hair, resulting in a change in pigmentation. Heat-damaged hair is <a href="https://pubmed.ncbi.nlm.nih.gov/21635854/">harder to brush</a>. The damage is even more devastating if you use heat styling tools such as <a href="https://labmuffin.com/why-you-should-never-straighten-or-curl-wet-hair/">curling irons or straighteners</a> to <a href="https://library.scconline.org/v062n01/23">heat wet hair</a>, as at the high treatment temperatures, the water soaked up by the fibres can violently evaporate. The result of this is succinctly described by science educator and cosmetic chemist Michelle Wong, also known as <a href="https://labmuffin.com/how-do-heat-protectant-hair-products-work/">Lab Muffin</a>. She notes if you heat wet hair this way, “steam will blast through your hair’s structure”. This steam bubbling or bursting through the hair can <a href="https://pubmed.ncbi.nlm.nih.gov/21443842/">cause substantial damage</a>. It’s worth noting hair dryers don’t concentrate heat in the same way as styling tools such as flat irons or curling wands, but you still need to move the hair dryer around constantly to avoid heat building up in one spot and causing damage. Once heat damage is done, regardless of whether it is severe or mild, the best remaining options are symptom management or a haircut. For all of these reasons, when you’re planning to heat treat your hair, protection is a good idea. <h2>How hair protectants work</h2> When you spray on a hair protectant, many possible key ingredients can go to work. They can have <a href="https://library.scconline.org/v062n01/15">daunting-looking names</a> like polyvinyl pyrrolidone, methacrylates, polyquaterniums, silicones and more. These materials are chosen because they readily stick onto your hair, creating a coating, a bit like this: <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=225&fit=crop&dpr=1 600w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=225&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=225&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=283&fit=crop&dpr=1 754w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=283&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/615002/original/file-20240822-16-beyt90.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=283&fit=crop&dpr=3 2262w" alt="A cartoon of coating attached to a strand of hair." /></a><figcaption>Hair protectant applies a coating to your hair.

Flu shots play an important role in protecting against bird flu. But not for the reason you might think

<a href="https://theconversation.com/profiles/allen-cheng-94997">Allen Cheng</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> A current strain of highly pathogenic avian influenza, commonly known as bird flu, has become a global problem. The virus has affected <a href="https://www.cdc.gov/bird-flu/situation-summary/data-map-commercial.html">many millions</a> of birds, some other <a href="https://www.cdc.gov/bird-flu/situation-summary/mammals.html">animal species</a>, and a <a href="https://cdn.who.int/media/docs/default-source/influenza/avian-and-other-zoonotic-influenza/joint-fao-oie-who-preliminary-risk-assessment-associated-with-avian-influenza-a(h5n1)-virus.pdf?sfvrsn=faa6e47e_28&download=true">small number of people</a>. Last week, the Australian government <a href="https://www.sbs.com.au/news/article/australians-issued-new-health-risks-travel-warning-for-europe-asia-and-the-americas/gmh1hk9py">issued a warning</a> to residents travelling to Europe, North America, South America and Asia about the risk of bird flu. The alert, published on the <a href="https://www.smartraveller.gov.au/news-and-updates/highly-pathogenic-avian-influenza-outbreak">Smartraveller website</a>, included advice to ensure your flu vaccine is up to date. If you are about to go travelling, this generally means if you’ve had a flu jab this year, although if it has been 3–6 months since your vaccine you should discuss this with your doctor. But the seasonal flu vaccine we get each year doesn’t actually prevent bird flu in humans. So why is it being recommended in this context? <h2>Some bird flu background</h2> Smartraveller notes <a href="https://www.smartraveller.gov.au/news-and-updates/highly-pathogenic-avian-influenza-outbreak">several strains</a> of bird flu are currently circulating. The most concerning strain, called the <a href="https://www.nature.com/articles/s41467-023-38415-7">2.3.4.4b clade</a>, emerged a few years ago from a type of influenza A (H5, or A/H5) that has been circulating for several decades. Clade 2.3.4.4b primarily affects birds, including wild birds and poultry. It has had <a href="https://theconversation.com/uk-poultry-can-roam-free-outside-again-but-bird-flu-risk-hasnt-gone-away-203361">devastating effects</a> on bird populations, as well as farmers and others involved in the poultry industry. In recent years, clade 2.3.4.4b has adapted to <a href="https://www.nature.com/articles/s44298-024-00039-z">infect some mammals</a>. Unfortunately it seems to cause severe disease in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11083745/">certain animals</a>. Some marine mammals have been hit particularly hard, with mass mortality events <a href="https://www.theguardian.com/environment/2023/dec/08/mass-deaths-elephant-seals-penguins-bird-flu-antarctic-ecological-disaster-aoe">reported</a> in elephant seals and sea lions. In the United States, bird flu has also spread <a href="https://www.cdc.gov/bird-flu/situation-summary/mammals.html">among dairy cows</a>. Compared to the huge number of animal cases, there have been a relatively small number of <a href="https://www.who.int/publications/m/item/joint-fao-who-woah-preliminary-assessment-of-recent-influenza-a(h5n1)-viruses">humans infected with bird flu</a>. Since 2003, <a href="https://www.who.int/publications/m/item/cumulative-number-of-confirmed-human-cases-for-avian-influenza-a(h5n1)-reported-to-who--2003-2023--3-october-2023">878 cases</a> of A/H5N1 influenza have been reported in humans, with a small proportion of these reported since 2020 when <a href="https://www.outbreak.gov.au/emerging-risks/high-pathogenicity-avian-influenza">clade 2.3.4.4b first emerged</a>. The reported cases have been people who have had close contact with infected animals. It does not appear to spread from person to person. As such, the <a href="https://www.ecdc.europa.eu/en/infectious-disease-topics/z-disease-list/avian-influenza/threats-and-outbreaks/risk-assessment-h5">risk to travellers is low</a>. There are some situations where the risk may be greater, such as for people visiting live markets, or those who are travelling specifically to work with wildlife or animals in food production. <a href="https://www.who.int/publications/m/item/joint-fao-who-woah-preliminary-assessment-of-recent-influenza-a(h5n1)-viruses">Infections in humans</a> with H5 influenza can vary significantly in severity, from mild conjunctivitis up to fatal pneumonia. H5 influenza strains appear to be <a href="https://asm.org/articles/2024/june/what-you-should-know-about-avian-influenza-a-h5n1">sensitive to antivirals</a> (oseltamivir, also known as Tamiflu) and they are generally <a href="https://www.cdc.gov/bird-flu/hcp/novel-av-treatment-guidance/">recommended</a> as treatment for human infection, but it’s <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)01307-2/fulltext">not clear</a> whether they reduce the risk of death in those with severe disease. To date, one case of A/H5 influenza (not 2.3.4.4b) has been <a href="https://www.abc.net.au/news/2024-05-22/bird-flu-avian-influenza-human-detection/103879886">reported in Australia</a>, in a child who had recently returned from overseas. While <a href="https://www.fao.org/animal-health/situation-updates/global-aiv-with-zoonotic-potential/en">clade 2.3.4.4b has been detected</a> in all continents <a href="https://www.outbreak.gov.au/emerging-risks/high-pathogenicity-avian-influenza">except Australia</a>, other avian influenza strains (A/H7) <a href="https://www.outbreak.gov.au/current-outbreaks/avian-influenza">have been reported here</a> earlier this year. <h2>Seasonal flu vaccines are not effective against bird flu</h2> Seasonal influenza refers to the flu strains that circulate each year. Since the COVID pandemic, three different strains have circulated in various proportions – influenza A H1N1 (descended from the <a href="https://www.nature.com/articles/nature08182">2009 swine flu strain</a>), influenza A H3N2 (which has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6149781/">circulated since 1968</a>) and an influenza B strain. Interestingly, a second influenza B strain (the Yamagata lineage) <a href="https://www.nejm.org/doi/full/10.1056/NEJMp2314801">appears to have vanished</a> during the COVID pandemic. Seasonal influenza vaccines contain up-to-date variants of these types (A/H1N1, A/H3N2 and B) that are recommended by the World Health Organization each year. They are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5912669/">moderately effective</a>, reducing the risk of hospitalisation by about 40–60%. Influenza vaccines are quite specific in the protection that they provide. For seasonal vaccines, even the very small changes that occur in the virus from year to year are enough to allow them to “escape” vaccine-induced immunity. Therefore seasonal flu vaccines <a href="https://www.cdc.gov.au/topics/avian-influenza-bird-flu">do not provide any protection</a> against A/H5 influenza. <h2>Preventing a hybrid bird-human strain</h2> The rationale for recommending travellers have a flu shot in the context of the current bird flu outbreak is that seasonal flu vaccines may help reduce the risk of simultaneous infection with both A/H5 and a seasonal influenza strain. When this occurs, there is potential for a “recombination” of the genetic code from both viral strains. This could have the transmissibility of a seasonal human virus with the severity of an avian influenza virus. The 2009 swine flu strain <a href="https://www.nejm.org/doi/full/10.1056/NEJMra0904322">arose from the recombination</a> of several strains over years to become more transmissible in humans. Obviously a more effective vaccine would include a H5 strain, to generate immune responses specific to the H5 flu strain. Vaccine manufacturers have <a href="https://www.ema.europa.eu/en/medicines/human/EPAR/celldemic">developed H5 vaccines</a> over the years, but to date <a href="https://thl.fi/en/-/avian-influenza-vaccinations-begin-vaccine-to-be-offered-to-persons-at-increased-risk-of-infection">only Finland</a> has deployed a H5 vaccine in a small group of people who work closely with potentially infected animals. Currently the <a href="https://www.ecdc.europa.eu/en/infectious-disease-topics/z-disease-list/avian-influenza/threats-and-outbreaks/risk-assessment-h5">level of risk</a> posed by H5 to humans is not thought to be sufficient to require a specific vaccine program, as the potential benefits are small compared to the costs and the potential risks associated with any new vaccine program. <h2>The value of a flu shot for travellers</h2> Seasonal flu vaccines protect against influenza infection, and may also reduce the risk of simultaneous infection with human and bird flu strains. Bird flu aside, for most travellers who haven’t received a flu shot this year, reducing the risk of illness disrupting travel plans should be enough of a reason to get one. For those who have already received a flu shot this season, similar to COVID jabs, protection after vaccination appears to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8499703/">wane over time</a>. So if you’re travelling to the northern hemisphere during the winter months, and it’s been more than 3–6 months since you received a flu vaccine, your doctor may recommend you have another. Bird flu is only a small risk to most travellers, but people may want to take sensible precautions, such as avoiding close contact with birds at markets.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237859/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/allen-cheng-94997">Allen Cheng</a>, Professor of Infectious Diseases, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Second marriage asset protection: What you need to know

Of paramount importance for many people in a second marriage is how to protect their assets if their relationship breaks down, or in the event of their death. Although second marriages bring a level of complexity, there are a number of strategies that you can implement to ensure that your assets are protected. Let’s explore some of the options available to you and what you need to know to protect your assets. Binding Financial Agreement A Binding Financial Agreement, often referred to as a pre-nup, allows you and your spouse to put in place a legal agreement which outlines how your assets will be dealt with in the event that your relationship breaks down. Should you wish, it can also extend to the provision of financial support for either party. The intention is for each party to protect their own assets, and such agreements can be put in place prior to a marriage or during a marriage if both parties consent. Like any legal document, a Binding Financial Agreement needs to be well drafted to ensure that it encompasses all relevant information, and it is important that you seek the advice of a family lawyer to assist you with putting this important document in place. Joint Assets v Individual Assets The manner in which you hold your assets is of paramount importance. All joint assets pass to the surviving party. If you and your spouse own a property as joint proprietors upon your death this property will automatically pass to your spouse. By changing the manner in which you hold the property from joint proprietors to tenants in common allows you and your spouse to deal with your individual interest in the property in your respective Wills. Additionally, you need to be mindful of any bank accounts or other investments that you hold jointly with your spouse as these are not individual assets that you can make provision for and will pass to your spouse upon your death. Your Will It is imperative that you put a Will in place that is reflective of your current circumstances and adequately provides for both your spouse and your children from a previous relationship in the manner that you desire. For many parents in second marriages with children from a previous relationship, protecting their children’s inheritance is of paramount importance. Discretionary Testamentary Trusts which are created in accordance with the provisions of your Will, can make provision for your spouse during their lifetime, whilst also ensuring that most of your assets go to your children. If you are the sole registered proprietor of your residence in which you and your spouse reside you may make provision in your Will providing a life interest in your residence to your spouse subject to some conditions being adhered to. This will allow your spouse to reside in your residence for the duration of their life then subsequent to their death the property may then pass to your children. Dying without a valid Will in place deems that you died intestate, and your assets will be distributed in accordance with a government formula and may not end up with the people who you would like to receive them. Your spouse would be entitled to a share of your assets, however this may not have been your intention, or the share that they would receive may be significantly more than you would like them to receive. It is therefore crucial that you take the time to put a well drafted Will in place so that your assets pass to those who you would like to receive them upon your death. Mutual Wills Agreement A Mutual Wills Agreement is a separate document to your Will and essentially is an agreement between you and your spouse that both of you will not change your Will without the consent of the your spouse or their legal personal representative upon their death. This document is intended to prevent the remaining spouse from altering their Will and disinheriting step-children or making other adverse changes to their Will. The Right People in Key Roles The roles of executor of your Will and your attorney in respect to your Power of Attorney documents are important roles and it is paramount that you appoint trusted people to undertake these roles as essentially you are handing control of your assets to those who assume these roles. Your attorney is entrusted to look after your finances and provide the best care for you in the event that you become incapacitated so you need to choose wisely. Communication is Crucial It is important that there is transparency for you and your family. By having important conversations with your spouse and children you can openly discuss your intentions and expectations so that all parties are relevantly informed and fully understand what your wishes are and what you have put in place. In order to evaluate the best options for you it is important that you obtain the appropriate professional advice to determine which is the best strategy for your own individual circumstances so that the relevant documents are put in place which offer you the best asset protection possible.

What you need to know about protecting your children’s inheritance

For many people, ensuring that their children’s inheritance is protected is of paramount importance to them. There are a number of strategies that you can put in place to achieve this objective, you just need to determine which one bests suits you and your family’s circumstances. Put a Will in place By putting a Will in place, you get to decide who your assets go to, allowing you to make provision in your Will for them to pass to your children upon your death. If you do not have a Will in place then it is up to the government where your assets get paid and this may mean that your assets do not pass to your children, or do not pass to them in the manner that you desire. Play it safe and ensure things go the way you want them by taking the time to put a Will in place. Testamentary trust Let me introduce you to Testamentary Trusts. These amazing vehicles allow you to transfer your wealth to your children in the most asset protective and tax effective way possible. With an increasing number of marriages crumbling and divorce rates soaring, the last thing you want is your hard earned wealth passing to your child’s estranged partner in the event of one of your child’s marriage breakdown. By making provision in your Will leaving your children’s inheritance in a Testamentary Trust it protects their inheritance from any divorce or family law risks if your child’s relationship breaks down. Additionally, you may have a child who works in a high-risk occupation – a doctor, financial advisor or perhaps carrying on the role of a director. Alternatively, your child may be an entrepreneur, taking risks in their own business operations. If something adverse happened to your child whilst they were undertaking these roles and they were sued, they could be personally liable for them for any actions brought upon them by the aggrieved party. Creditors and other associated parties could only seek recourse to moneys owed by your child from them in their own personal capacity. If your child had received their inheritance in their own name, and hence the assets were now individual assets, the creditors and other associated parties would have recourse in recovering funds owed to them by your child. However, if your child’s inheritance was paid to a Testamentary Trust for their benefit at the time of your death then these assets would be held on trust for them and are not personal assets, hence the creditors and other associated parties would not have recourse in respect to these assets. Blended marriages If you have children from a previous marriage, it’s imperative that you obtain the appropriate legal advice in respect to how to protect your assets for your children. There are a number of options that you can put in place including a Binding Financial Agreement and a Mutual Wills Agreement. There are also strategies that you can put in place which ensure that your assets pass to your children upon your death. Options are also available where you may wish for your partner to receive some benefit of some of your assets during your lifetime with all assets passing to your children upon your partner’s death. Choose the right executor If you have young children, it will be your executor who looks after your children’s inheritance until your children reach the age that you have stipulated in your Will that you would like them to receive your assets. It is therefore imperative that you have the best person possible to undertake this role as you are effectively giving them the keys to everything that you own and control. That’s big. You need to appoint someone that you trust implicitly to undertake this role. You need to appoint your most trusted ally. Your executor also needs to be financial savvy or receptive to obtaining the appropriate financial advice to enable them to look after and grow your children’s inheritance. It is important that you seek the appropriate advice so that you can put the best strategies in place that protect your children’s inheritance in the best manner possible. There are a number of ways that you can protect your children’s inheritance, you just need to find the best one that works for you and your children.

Better sleep is a protective factor against dementia

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Dementia is a progressive loss of cognitive abilities, such as memory, that is significant enough to have an impact on a person’s daily activities. It can be caused by a number of different diseases, including <a href="https://alzheimer.ca/en/about-dementia/what-alzheimers-disease">Alzheimer’s</a>, which is the most common form. Dementia is caused by a loss of neurons over a long period of time. Since, by the time symptoms appear, many changes in the brain have already occurred, many scientists are focusing on studying the risk and protective factors for dementia. A risk factor, or conversely, a protective factor, is a condition or behaviour that increases or reduces the risk of developing a disease, but does not guarantee either outcome. Some risk factors for Alzheimer’s disease and dementia, such as age or genetics, are not modifiable, but there are several other factors we can influence, <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">specifically lifestyle habits and their impact on our overall health</a>. These risk factors include depression, lack of physical activity, social isolation, high blood pressure, obesity, diabetes, excessive alcohol consumption and smoking, as well as poor sleep. We have been focusing our research on the question of sleep for over 10 years, particularly in the context of the <a href="https://www.nhlbi.nih.gov/science/framingham-heart-study-fhs">Framingham Heart Study</a>. In this large community-based cohort study, ongoing since the 1940s, the health of surviving participants has been monitored to the present day. As researchers in sleep medicine and epidemiology, we have expertise in researching the role of sleep and sleep disorders in cognitive and psychiatric brain aging. As part of our research, we monitored and analyzed the sleep of people aged 60 and over to see who did — or did not — develop dementia. <h2>Sleep as a risk or protective factor against dementia</h2> Sleep appears to play an essential role in a number of brain functions, such as memory. Good quality sleep <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2793873">could therefore play a vital role in preventing dementia</a>. Sleep is important for maintaining <a href="https://www.science.org/doi/10.1126/science.1241224">good connections in the brain</a>. Recently, research has revealed that sleep seems to have a function similar to that of a garbage truck for the brain: <a href="https://doi.org/10.1016/j.mad.2023.111899">deep sleep could be crucial for eliminating metabolic waste from the brain</a>, including clearing certain proteins, such as those known to accumulate in the brains of people with Alzheimer’s disease. However, the links between deep sleep and dementia still have to be clarified. <h2>What is deep sleep?</h2> During a night’s sleep, we go through several <a href="http://ceams-carsm.ca/en/a-propos-du-sommeil/">sleep stages</a> that succeed one another and are repeated. NREM sleep (non-rapid eye movement sleep) is divided into light NREM sleep (NREM1 stage), NREM sleep (NREM2 stage) and deep NREM sleep, also called slow-wave sleep (NREM3 stage). The latter is associated with several restorative functions. Next, REM sleep (rapid eye movement sleep) is the stage generally associated with the most vivid dreams. An adult generally spends around 15 to 20 per cent of each night in deep sleep, if we add up all the periods of NREM3 sleep. Several sleep changes are common in adults, such as going to bed and waking up earlier, sleeping for shorter periods of time and less deeply, and waking up more frequently during the night. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=279&fit=crop&dpr=1 600w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=279&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=279&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=350&fit=crop&dpr=1 754w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=350&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/579041/original/file-20240229-16-efo9mx.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=350&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Sleep stages, and the role of deep sleep for brain health. (Andrée-Ann Baril)</figcaption></figure> <h2>Loss of deep sleep linked to dementia</h2> Participants in the <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2810957">Framingham Heart Study</a> were assessed using a sleep recording — known as polysomnography — on two occasions, approximately five years apart, in 1995-1998 and again in 2001-2003. Many people showed a reduction in their deep slow-wave sleep over the years, as is to be expected with aging. Conversely, the amount of deep sleep in some people remained stable or even increased. Our team of researchers from the Framingham Heart Study followed 346 participants aged 60 and over for a further 17 years to observe who developed dementia and who did not. Progressive loss of deep sleep over time was associated with an increased risk of dementia, whatever the cause, and particularly Alzheimer’s type dementia. These results were independent of many other risk factors for dementia. Although our results do not prove that loss of deep sleep causes dementia, they do suggest that it could be a risk factor in the elderly. Other aspects of sleep may also be important, such as its duration and quality. <h2>Strategies to improve deep sleep</h2> Knowing the impact of a lack of deep sleep on cognitive health, what strategies can be used to improve it? First and foremost, if you’re experiencing sleep problems, it’s worth talking to your doctor. Many sleep disorders are underdiagnosed and treatable, particularly through behavioural (i.e. non-medicinal) approaches. Adopting good sleep habits can help, such as going to bed and getting up at consistent times or avoiding bright or blue light in bed, like that of screens. You can also avoid caffeine, limit your alcohol intake, maintain a healthy weight, be physically active during the day, and sleep in a comfortable, dark and quiet environment. The role of deep sleep in preventing dementia remains to be explored and studied. Encouraging sleep with good lifestyle habits could have the potential to help us age in a healthier way.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222854/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andree-ann-baril-1494268">Andrée-Ann Baril</a>, Professeure-chercheure adjointe au Département de médecine, <a href="https://theconversation.com/institutions/universite-de-montreal-1743">Université de Montréal</a> and <a href="https://theconversation.com/profiles/matthew-pase-1494296">Matthew Pase</a>, Associate Professor of Neurology and Epidemiology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What ‘psychological warfare’ tactics do scammers use, and how can you protect yourself?

<a href="https://theconversation.com/profiles/mike-johnstone-106590">Mike Johnstone</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/georgia-psaroulis-1513050">Georgia Psaroulis</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Not a day goes by without a headline <a href="https://www.vice.com/en/article/qjvaym/people-share-worst-scam-stories">about a victim being scammed</a> and losing money. We are constantly warned about new scams and staying safe from cybercriminals. Scamwatch has <a href="https://www.scamwatch.gov.au/research-and-resources/tools-resources/online-resources/spot-the-scam-signs">no shortage of resources</a>, too. So why are people still getting scammed, and sometimes spectacularly so? Scammers use sophisticated psychological techniques. They exploit our deepest human vulnerabilities and bypass rational thought to tap into our emotional responses. This “<a href="https://www.thecut.com/article/amazon-scam-call-ftc-arrest-warrants.html">psychological warfare</a>” coerces victims into making impulsive decisions. Sometimes scammers spread their methods around many potential victims to see who is vulnerable. Other times, criminals focus on a specific person. Let’s unpack some of these psychological techniques, and how you can defend against them. <h2>1. Random phone calls</h2> Scammers start with small requests to establish a sense of commitment. After agreeing to these minor requests, we are more likely to comply with larger demands, driven by a desire to act consistently. The call won’t come from a number in your contacts or one you recognise, but the scammer may pretend to be someone you’ve engaged to work on your house, or perhaps one of your children using a friend’s phone to call you. If it is a scammer, maybe keeping you on the phone for a long time gives them an opportunity to find out things about you or people you know. They can use this info either immediately or at a later date. <h2>2. Creating a sense of urgency</h2> Scammers fabricate scenarios that require immediate action, like claiming a bank account is at risk of closure or an offer is about to expire. This tactic aims to prevent victims from assessing the situation logically or seeking advice, pressuring them into rushed decisions. The scammer creates an artificial situation in which you are frightened into doing something you wouldn’t ordinarily do. Scam calls <a href="https://theconversation.com/we-have-filed-a-case-under-your-name-beware-of-tax-scams-theyll-be-everywhere-this-eofy-162171">alleging to be from the Australian Tax Office</a> (ATO) are a great example. You have a debt to pay (apparently) and things will go badly if you don’t pay right now. Scammers play on your emotions to provoke reactions that cloud judgement. They may threaten legal trouble to instil fear, promise high investment returns to exploit greed, or share fabricated distressing stories to elicit sympathy and financial assistance. <h2>3. Building rapport with casual talk</h2> Through extended conversation, scammers build a psychological commitment to their scheme. No one gets very far by just demanding your password, but it’s natural to be friendly with people who are friendly towards us. After staying on the line for long periods of time, the victim also becomes cognitively fatigued. This not only makes the victim more open to suggestions, but also isolates them from friends or family who might recognise and counteract the scam. <h2>4. Help me to help you</h2> In this case, the scammer creates a situation where they help you to solve a real or imaginary problem (that they actually created). They work their “IT magic” and the problem goes away. Later, they ask you for something you wouldn’t normally do, and you do it because of the “social debt”: they helped you first. For example, a hacker might attack a corporate network, causing it to slow down. Then they call you, pretending to be from your organisation, perhaps as a recent hire not yet on the company’s contact list. They “help” you by turning off the attack, leaving you suitably grateful. Perhaps a week later, they call again and ask for sensitive information, such as the CEO’s password. You know company policy is to not divulge it, but the scammer will ask if you remember them (of course you do) and come up with an excuse for why they really need this password. The balance of the social debt says you will help them. <h2>5. Appealing to authority</h2> By posing as line managers, officials from government agencies, banks, or other authoritative bodies, scammers exploit our natural tendency to obey authority. Such scams operate at varying levels of sophistication. The simple version: your manager messages you with an urgent request to purchase some gift cards and send through their numbers. The complex version: your manager calls and asks to urgently transfer a large sum of money to an account you don’t recognise. You do this because <a href="https://www.wsj.com/articles/fraudsters-use-ai-to-mimic-ceos-voice-in-unusual-cybercrime-case-11567157402">it sounds exactly</a> like your manager on the phone – but the scammer <a href="https://www.forbes.com/sites/thomasbrewster/2021/10/14/huge-bank-fraud-uses-deep-fake-voice-tech-to-steal-millions/?sh=1329b80e7559">is using a voice deepfake</a>. In a recent major case in Hong Kong, such a scam even involved a <a href="https://edition.cnn.com/2024/02/04/asia/deepfake-cfo-scam-hong-kong-intl-hnk/index.html">deepfake video call</a>. This is deeply challenging because artificial intelligence tools, such as Microsoft’s VALL-E, can create <a href="https://arstechnica.com/information-technology/2023/01/microsofts-new-ai-can-simulate-anyones-voice-with-3-seconds-of-audio/">a voice deepfake</a> using just three seconds of sampled audio from a real person. <h2>How can you defend against a scam?</h2> First and foremost, verify identity. Find another way to contact the person to verify who they are. For example, you can call a generic number for the business and ask to be connected. In the face of rampant voice deepfakes, it can be helpful to agree on a “safe word” with your family members. If they call from an unrecognised number and you don’t hear the safe word just hang up. Watch out for pressure tactics. If the conversation is moving too fast, remember that someone else’s problem is not yours to solve. Stop and run the problem past a colleague or family member for a sanity check. A legitimate business will have no problem with you doing this. Lastly, if you are not sure about even the slightest detail, the simplest thing is to hang up or not respond. If you really owe a tax debt, the ATO will write to you.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223959/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mike-johnstone-106590">Mike Johnstone</a>, Security Researcher, Associate Professor in Resilient Systems, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/georgia-psaroulis-1513050">Georgia Psaroulis</a>, Postdoctoral research fellow, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is doxing, and how can you protect yourself?

<a href="https://theconversation.com/profiles/rob-cover-13135">Rob Cover</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> The Australian government has brought forward <a href="https://www.theguardian.com/australia-news/2024/feb/12/albanese-government-to-propose-legislation-to-crack-down-on-doxing">plans to criminalise doxing</a>, bringing nationwide attention to the harms of releasing people’s private information to the wider public. The government response comes after the <a href="https://www.smh.com.au/national/hundreds-of-jewish-creatives-have-names-details-taken-in-leak-published-online-20240208-p5f3if.html">public release of almost 600 names</a> and private chat logs of a WhatsApp group of Australian Jewish creative artists discussing the Israel-Hamas war. As a result, some of the people whose details were leaked claim they were harassed, <a href="https://www.theguardian.com/australia-news/2024/feb/09/josh-burns-jewish-whatsapp-group-channel-publication-israel-palestine-clementine-ford">received death threats</a> and even had to go into hiding. While we wait for <a href="https://www.smh.com.au/national/australia-news-live-federal-laws-on-doxxing-to-be-brought-forward-anniversary-of-stolen-generations-apology-20240213-p5f4eh.html?post=p55nen#p55nen">new penalties</a> for doxers under the federal Privacy Act review, understanding doxing and its harms can help. And there are also steps we can all take to minimise the risk. <h2>What is doxing?</h2> <a href="https://www.kaspersky.com/resource-center/definitions/what-is-doxing">Doxing</a> (or doxxing) is releasing private information — or “docs”, short for documents — online to the wider public without the user’s consent. This includes information that may put users at risk of harm, especially names, addresses, employment details, medical or financial records, and names of family members. The Australian government <a href="https://ministers.ag.gov.au/media-centre/transcripts/media-conference-parliament-house-13-02-2024">currently defines doxing</a> as the “malicious release” of people’s private information without their consent. Doxing began as a form of unmasking anonymous users, trolls and those using hate speech while <a href="https://www.theatlantic.com/technology/archive/2022/04/doxxing-meaning-libs-of-tiktok/629643/">hiding behind a pseudonym</a>. Recently, it has become a weapon for online abuse, harassment, hate speech and adversarial politics. It is often the outcome of online arguments or polarised public views. It is also becoming more common. Although there is no data for Australia yet, according to media company <a href="https://www.safehome.org/family-safety/doxxing-online-harassment-research/">SafeHome.org</a>, about 4% of Americans report having been doxed, with about half saying their private emails or home addresses have been made public. Doxing is a crime in some countries such as the Netherlands and South Korea. In other places, including Australia, privacy laws haven’t yet caught up. <h2>Why is doxing harmful?</h2> In the context of the <a href="https://theconversation.com/au/topics/israel-hamas-war-146714">Israel-Hamas war</a>, doxing has affected <a href="https://www.haaretz.com/world-news/asia-and-australia/2024-02-06/ty-article/death-threats-boycotts-target-jewish-creatives-in-australia/0000018d-7e43-d636-adef-7eefae580000">both Jewish</a> and <a href="https://edition.cnn.com/2023/10/15/business/palestinian-americans-activists-doxxing/index.html">pro-Palestinian communities and activists</a> in Australia and abroad. Doxing is harmful because it treats a user as an object and takes away their agency to decide what, and how much, personal information they want shared with the wider public. This puts people at very real risk of physical threats and violence, particularly when public disagreement becomes heated. From a broader perspective, doxing also damages the digital ecology, reducing people’s ability to freely participate in public or even private debate through social media. Although doxing is sometimes just inconvenient, it is often used to publicly shame or humiliate someone for their private views. This can take a toll on a person’s mental health and wellbeing. It can also affect a person’s employment, especially for people whose employers require them to keep their attitudes, politics, affiliations and views to themselves. Studies have shown doxing particularly impacts <a href="https://journals.sagepub.com/doi/full/10.1177/0306422015605714">women</a>, including those using dating apps or experiencing family violence. In some cases, children and family members have been threatened because a high-profile relative has been doxed. Doxing is also harmful because it oversimplifies a person’s affiliations or attitudes. For example, releasing the names of people who have joined a private online community to navigate complex views can represent them as only like-minded stereotypes or as participants in a group conspiracy. <h2>What can you do to protect yourself from doxing?</h2> Stronger laws and better platform intervention are necessary to reduce doxing. Some experts believe that the fear of <a href="https://dl.acm.org/doi/abs/10.1145/3476075">punishment</a> can help shape better online behaviours. These punishments may include criminal <a href="https://www.esafety.gov.au/report/what-you-can-report-to-esafety">penalties</a> for perpetrators and <a href="https://www.theaustralian.com.au/breaking-news/doxxing-attack-on-jewish-australians-prompts-call-for-legislative-change/news-story/9a2f3615dbf5594fb521a8959739e1f8#:%7E:text=Alongside%20legislative%20reform%2C%20the%20ECAJ,information%2C%E2%80%9D%20Mr%20Aghion%20said.">deactivating social media accounts</a> for repeat offenders. But better education about the risks and harms is often the best treatment. And you can also protect yourself without needing to entirely withdraw from social media: <ol> <li> never share a home or workplace address, phone number or location, including among a private online group or forum with trusted people </li> <li> restrict your geo-location settings </li> <li> avoid giving details of workplaces, roles or employment on public sites not related to your work </li> <li> avoid adding friends or connections on social media services of people you do not know </li> <li> if you suspect you risk being doxed due to a heated online argument, temporarily shut down or lock any public profiles </li> <li> avoid becoming a target by pursuing haters when it reaches a certain point. Professional and courteous engagement can help avoid the anger of those who might disagree and try to harm you. </li> </ol> Additionally, hosts of private online groups must be very vigilant about who joins a group. They should avoid the trap of accepting members just to increase the group’s size, and appropriately check new members (for example, with a short survey or key questions that keep out people who may be there to gather information for malicious purposes). Employers who require their staff to have online profiles or engage with the public should provide information and strategies for doing so safely. They should also provide immediate support for staff who have been doxed.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223428/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rob-cover-13135">Rob Cover</a>, Professor of Digital Communication and Co-Director of the RMIT Digital Ethnography Research Centre, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How to protect yourself from cyber-scammers over the festive period

<a href="https://theconversation.com/profiles/rachael-medhurst-1408437">Rachael Medhurst</a>, <a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a> The festive season is a time for joy, family and festive cheer. However, it’s also a prime target for cybercriminals. As online shopping ramps up, so does the risk of falling prey to cyber-attacks. That’s why it’s crucial to be extra vigilant about your <a href="https://blog.tctg.co.uk/12-cyber-security-tips-of-christmas">cybersecurity</a> during this time. Here are some essential tips to safeguard yourself and your data during the festive period: <h2>Phishing</h2> Phishing is when criminals use scam emails, text messages or phone calls to trick their victims. Their <a href="https://www.ncsc.gov.uk/collection/phishing-scams">goal</a> is often to make you visit a certain website, which may download a virus on to your computer, or steal bank details or other personal data. This type of scam tends to <a href="https://www.egress.com/blog/phishing/holiday-phishing-scam-guide">increase</a> at this time due to the amount of people having bought or received new gadgets and technology. Look out for there being no direct reference to your name in any communications, with wording such as “Dear Sir/Madam” or other terms such as “valued customer” being used instead. Grammar and spelling mistakes are also often present. Be wary of any suspicious links or attachments within emails too, and don’t click them. It’s better to contact the company directly to check if the message is genuine. You can also <a href="https://www.ncsc.gov.uk/collection/phishing-scams">report</a> suspicious messages and phishing scams to the government’s National Cyber Security Centre. <h2>Shopping safely online</h2> The convenience of online shopping is undeniable, especially during the festive season. However, it’s crucial to prioritise your security when buying online. Before entering your personal and financial information on any website, ensure it’s legitimate and secure. Look for the “https” in the address bar and a <a href="https://theconversation.com/the-vast-majority-of-us-have-no-idea-what-the-padlock-icon-on-our-internet-browser-is-and-its-putting-us-at-risk-216581">padlock</a> icon, which indicates a secure and encrypted connection. When creating passwords for online shopping accounts, use strong, unique combinations of letters, numbers and symbols. Avoid using the same password for multiple accounts, as a breach on one site could compromise all your others. As with shopping in the real world, be cautious when encountering offers that are significantly below usual prices or which make extravagant promises. Always conduct thorough research on the seller and product before making a purchase. If a deal seems too good to be true, it probably is. And if you are out shopping in towns or city centres, there will often be a large number of public wifi options available to you. However, criminals can intercept the data that is transferred across such open and unsecured wifi. So, avoid using public wifi where possible, especially when conducting any financial transactions. <h2>Social media</h2> While social media platforms provide people with a means to keep in touch with family and friends over the festive period, they are often a goldmine for <a href="https://www.which.co.uk/consumer-rights/advice/how-to-spot-a-social-media-scam-aMtwF3u1XKGt">scams</a> and malware (software designed to disrupt, damage or gain unauthorised access to a computer). In the spirit of the festive season, people often share an abundance of personal information on social media, often without considering the potential consequences. This trove of data can make people vulnerable to cyber-attacks. Scammers can exploit this information to gain unauthorised access to social media accounts, steal personal information, or even commit identity theft. To protect yourself, be mindful of what you share. Be wary when interacting with posts and direct messages, especially if they contain suspicious links or attachments. Before clicking on anything, hover over the link to verify its destination. If it shows a website you don’t recognise or seems unrelated to the message, do not click on it. If you receive a message from someone you know but the content seems strange or out of character, contact them directly through a trusted channel to verify its authenticity. Likewise, be wary of messages containing urgent requests for money or personal information from businesses. Genuine organisations will never solicit sensitive details through social media. There are many buy and sell platforms available on social media. But while such platforms can be a great place to find a unique gift, it is also important to remember that not all sellers may be legitimate. So, it’s vital that you don’t share your bank details. If the seller sends a link to purchase the item, do not use it. When meeting to collect an item, it’s generally safer to use cash rather than transferring funds electronically. <figure><iframe src="https://www.youtube.com/embed/aO858HyFbKI?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Advice for staying safe online.</figcaption></figure> <h2>Package delivery scams</h2> As well as being a time for giving and receiving gifts, the festive season is also ripe for cybercriminals to exploit the excitement surrounding <a href="https://www.citizensadvice.org.uk/about-us/about-us1/media/press-releases/scams-linked-to-parcel-deliveries-come-top-in-2023/">package deliveries</a>. Scammers often pose as legitimate delivery companies, sending emails or text messages claiming that a delivery attempt was unsuccessful or requiring additional fees for processing, or even customs clearance. Typically, these messages contain links or phone numbers that, when clicked or called, lead to fake websites or automated phone systems designed to collect personal information or payments. To protect yourself, always verify the legitimacy of any delivery notifications you receive. Check the sender’s email address or phone number against the official contact information for the delivery company. If the information doesn’t match or seems suspicious, don’t click any links or provide personal details. Legitimate delivery companies will never ask for upfront payment or sensitive information through unsolicited messages or calls. Remember, cybercriminals are skilled at manipulating the festive spirit to their advantage. Stay vigilant, exercise caution, and don’t let your excitement for gifts and deliveries compromise your cybersecurity.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/218294/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/rachael-medhurst-1408437">Rachael Medhurst</a>, Course Leader and Senior Lecturer in Cyber Security NCSA, <a href="https://theconversation.com/institutions/university-of-south-wales-1586">University of South Wales</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

If you have outdoor furniture, it’s important to look after it properly so it will stay in good condition over the years. Remember to invest in UV and water-resistant chair covers and pillows in order to ensure you can enjoy your outdoor furniture without the hassle of replacing all your items. Here’s how to care for your furniture. 1. Wooden To get your wooden outdoor furniture ready for use, clean with hot soapy water or a hardwood cleaning fluid at the beginning of the season. If the furniture is very dirty then you can lightly sand the furniture after cleaning. It is a good idea to oil or paint your outdoor furniture after cleaning. If you want your furniture to age naturally, then oil the furniture with two coats and leave to dry for 48 hours. Use hardwood oil for eucalyptus and teak oil for teak furniture. If you want your outdoor furniture to look new, then use a stained oil. If you want to completely transform your furniture then paint with 2-3 coats and it should last for roughly three years. 2. Metal When you wash your metal outdoor furniture be sure to clean it with a non-abrasive cloth. If the furniture is made from steel, you need to treat any scratches that expose the bare metal underneath to prevent rust. If rust has already set it on your furniture, remove it using steel wool and then touch it up using an exterior metal paint of the same colour. If your furniture is made from aluminium, it won’t rust but it may suffer from aluminium oxidation. This won’t decrease the strength of the furniture but it will change the colour of the metal over time. To prevent this from happening, make sure you clean it regularly and store it away or keep it covered during the winter months. One tip to keep your metal furniture in pristine condition is to polish it with car wax after you have finished cleaning it. The wax will help the furniture be more water resistant. 3. Rattan Synthetic rattan is UV and weather-resistant so it won’t be as worn out by the weather conditions. Whenever it needs a refresh, wash with soapy water. It is important to keep an eye on the frame underneath as if that is made from steel rather than aluminium, you will need to abide by the metal care rules. 4. Resin Resin outdoor furniture is fairly easy to look after. Wash it regularly with soap to keep it in great condition. If there is dirt or stains that are particularly hard to get out, then wash your furniture with a pressure washer. Image credits: Getty Images

Our planet is burning in unexpected ways - here’s how we can protect people and nature

It is a vital part of many ecosystems and cultures. Yet human activities in the current era, sometimes called the “<a href="https://theconversation.com/did-the-anthropocene-start-in-1950-or-much-earlier-heres-why-debate-over-our-world-changing-impact-matters-209869">Anthropocene</a>”, are reshaping patterns of fire across the planet. <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">In our new research</a>, published in the Annual Review of Environment and Resources, we used satellite data to create global maps of where and how fires are burning. We calculated about 3.98 million square kilometres of Earth’s land surface burns each year. We also examined research spanning archaeology, climatology, ecology, Indigenous knowledge and paleoecology, to better understand the causes and consequences of fires. Our international team found strong evidence fires are burning in unexpected places, at unusual times and in rarely observed ways. These changes in fire patterns are threatening human lives and modifying ecosystems. But the future does not have to be bleak. There are many opportunities to apply knowledge and practice of fire to benefit people and nature. <h2>Here’s how fire patterns are changing</h2> Exploring multiple approaches and scales enables a deeper understanding of where, when and how fires burn. Satellite data provide evidence of changes in fire patterns at a global scale. <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020RG000726">Annual fire season length</a> increased by 14 days from 1979 to 2020 and <a href="https://www.nature.com/articles/s41586-021-04325-1">night fires</a>, which indicate fires that cannot be quickly controlled, increased in intensity by 7.2% from 2003 to 2020. Other changes are apparent only when we look at data from particular regions. An increase in fire size and the frequency of large fires has recently been observed in <a href="https://www.pnas.org/doi/abs/10.1073/pnas.2103135118">forests and woodlands of the western United States</a>. Meanwhile fire-dependent grasslands and savannahs across <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.14711">Africa</a> and <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL082327">Brazil</a> have experienced reductions in fire frequency. It’s also important to consider the timescale and type of fire when interpreting changes. In Australia, <a href="https://www.nature.com/articles/s41467-021-27225-4">satellite records show</a> the frequency of very large forest fires has increased over the past four decades. At longer time scales, <a href="https://link.springer.com/article/10.1007/s13280-020-01339-3">charcoal and pollen records</a> indicate the frequency of low-intensity fires <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">decreased in parts of southeastern Australia</a> following British colonisation in 1788. <h2>Changes in fire affect air, land and water</h2> Many animals and plants have evolved strategies that enable them to thrive under particular fire patterns. This means changes to fire characteristics can <a href="https://www.science.org/doi/10.1126/science.abb0355">harm populations and ecosystems</a>. <a href="https://conbio.onlinelibrary.wiley.com/doi/full/10.1111/conl.12905">Large and intense fires</a> are reducing the available forest habitat preferred by the greater glider. But a <a href="https://theconversation.com/research-reveals-fire-is-pushing-88-of-australias-threatened-land-mammals-closer-to-extinction-185965">lack of fire can be problematic too</a>. Threatened species of native rodents can benefit from food resources and habitats that flourish shortly after fire. There is evidence that emissions from recent fires are already modifying the atmosphere. The historically exceptional 2019–20 Australian wildfires produced <a href="https://www.science.org/doi/10.1126/science.abe1415#:%7E:text=Intense%2C%20widespread%20bushfires%20in%20Australia,from%20a%20moderate%20volcanic%20eruption.">record-breaking levels of aerosols</a> over the Southern Hemisphere, as well as substantial carbon emissions. The <a href="https://www.nature.com/articles/s41893-020-00610-5">wildfire smoke-related health costs</a> of the 2019–20 wildfires in Australia included an estimated 429 smoke-related premature deaths as well as 3,230 hospital admissions for cardiovascular and respiratory disorders. Changes in fire patterns are modifying water cycles, too. In the western United States, <a href="https://www.pnas.org/doi/10.1073/pnas.2009717118">fires are reaching higher elevations</a> and having strong impacts on <a href="https://www.pnas.org/doi/10.1073/pnas.2200333119">snow</a> and water availability. New studies are revealing how the air, land and water that support life on Earth are connected by fires. Smoke plumes from the 2019–20 Australian wildfires transported nutrients to the Southern Ocean, resulting in <a href="https://www.nature.com/articles/s41586-021-03805-8">widespread phytoplankton blooms</a>. <h2>Humans are responsible for the changes</h2> Human drivers such as climate change, land use, fire use and suppression, and transportation and extinction of species <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">are causing shifts in fire patterns</a>. Increasing global temperatures and more frequent heatwaves and droughts increase the likelihood of fire by promoting hot, dry and windy conditions. A pattern of extreme fire weather outside of natural climate variation is already emerging in <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.15388">North America</a>, <a href="https://link.springer.com/article/10.1007/s10584-014-1183-3">southern Europe</a> and <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac1e3a/meta">the Amazon basin</a>. Humans modify fire regimes by changing land use for agricultural, forestry and urban purposes. Until recent decades, large fires in tropical forests were uncommon. But <a href="https://www.nature.com/articles/s41586-021-03876-7">deforestation fires</a> used to clear primary forest for agriculture often promotes more frequent and intense uncontrolled fires. Humans have transported plants and animals across the globe, resulting in novel mixes of species that modify fuels and fire regimes. In many parts of the world, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1908253116">invasive grasses</a> have increased flammability and fire activity. Social and economic changes propel these drivers. Colonisation by Europeans and the displacement of Indigenous peoples and their skilful use of fire has been linked with fire changes in <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/fee.2395">Australia</a>, <a href="https://www.pnas.org/doi/10.1073/pnas.2116264119">North America</a> and <a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2015.0174">South America</a>. <h2>Using knowledge and practice of fire to achieve sustainability goals</h2> <a href="https://www.annualreviews.org/doi/abs/10.1146/annurev-environ-120220-055357">The pace and scale of these changes</a> represent challenges to humanity, but knowledge and practice of fire can help to achieve sustainability goals. This includes: <ul> <li><a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2015.0174">good health and wellbeing</a>, by supporting community-owned solutions and fire practices that increase social cohesion and health</li> <li><a href="https://www.sciencedirect.com/science/article/pii/S0301479718314658">sustainable cities and communities</a>, by designing green firebreaks and mixed-use areas with low fuels, strategically located in the landscape</li> <li><a href="https://www.science.org/doi/10.1126/science.aam7672">life on land</a>, by tailoring use of fire to promote and restore species and ecosystems</li> <li><a href="https://www.nature.com/articles/s41561-021-00867-1">climate action</a>, by applying low-intensity fire to promote the stability of soil organic matter and increase carbon storage</li> <li><a href="https://www.mdpi.com/1660-4601/18/8/3921">reduced inequalities</a>, by allocating resources before, during, and after wildfires to at-risk communities and residents.</li> </ul> As the world changes, society as a whole needs to keep learning about the interplay between people and fire.

Finding a live brain worm is rare. 4 ways to protect yourself from more common parasites

<a href="https://theconversation.com/profiles/vincent-ho-141549">Vincent Ho</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> <a href="https://www.theguardian.com/australia-news/2023/aug/28/live-worm-living-womans-brain-australia-depression-forgetfulness">News reports</a> this morning describe how shocked doctors removed a live worm from a woman’s brain in a Canberra hospital last year. The woman had previously been admitted to hospital with stomach symptoms, dry cough and night sweats and months later experienced depression and forgetfulness that led to a brain scan. In the <a href="https://wwwnc.cdc.gov/eid/article/29/9/23-0351_article">case study</a> published in Emerging Infectious Diseases journal, doctors describe removing the live 8cm-long nematode (roundworm) from the brain of the 64-year-old woman who was immunosuppressed. The worm was identified as O. robertsi which is native to Australia, where it lives on carpet pythons. The woman may have come into contact with worm eggs via snake faeces while foraging for Warrigal greens to eat. It’s important to note this is an extremely rare event and headlines about brain worms can be alarming. But there are more common parasites which can infect your body and brain. And there are ways you can minimise your risks of being infected with one. <h2>Common parasites and how they get in</h2> Parasitic infection is extremely common. Arguably the most widespread type is pinworm (Enterobius vermicularis also called threadworm), which is thought to be present in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6522669/">over a billion people</a> worldwide, especially children. Pinworms grow to around 1cm in length and are specific to human hosts. They cause intense bottom itching and get passed from person-to-person. It’s a myth that you can get it from pets. <a href="https://www.cdc.gov/parasites/giardia/pathogen.html#:%7E:text=Giardia%20duodenalis%20is%20a%20protozoan,Giard%20of%20Paris%20and%20Dr.">Giardia</a> (Giardia duodenalis) is also very common and can contaminate food, water and surfaces. This water-borne parasite is associated with poor sanitation and causes stomach symptoms like diarrhoea, cramps, bloating, nausea and fatigue. Giardia cysts (little sacs of immature parasite) spread disease and are passed out in faeces, where they can remain viable in the environment for months before being consumed by someone else. They can also be ingested via foods (such as sheep meat) that is raw or undercooked. <a href="https://www.cdc.gov/dpdx/hookworm/index.html">Two types</a> of hookworm – Necator americanis and Ancylostoma duadonale – are found in soil. Only Ancylostoma duodenale is an issue in Australia and is typically found in <a href="https://www.cdc.gov/dpdx/hookworm/index.html">remote communities</a>. When a person is infected (usually via barefeet or contaminated footwear) these worms enter the bloodstream and then hit the lungs. From the bronchi in the upper lungs, they are swallowed with secretions. Once in the gut and small bowel they can <a href="https://www.who.int/news-room/fact-sheets/detail/soil-transmitted-helminth-infections#:%7E:text=Transmission,these%20eggs%20contaminate%20the%20soil.">cause anaemia</a> (low iron). This is because they are consuming nutrients and affecting iron absorption. They also release an anticoagulant that stops the human host’s blood clotting and causes tiny amounts of blood loss. Fortunately, these very common parasites do not infect the brain. Across the world, it’s estimated <a href="https://pubmed.ncbi.nlm.nih.gov/22491772/">30–50% of people</a> are infected with Toxoplasma. Most people will be asymptomatic but many carry the <a href="https://theconversation.com/one-in-three-people-are-infected-with-toxoplasma-parasite-and-the-clue-could-be-in-our-eyes-182418">signs of infection</a>. The parasites can remain in the body for years as tiny tissue cysts. These cysts can be found in brain, heart and muscle. Infants can be born with serious eye or brain damage if their mothers are infected during pregnancy. People with compromised immunity – such as from AIDS or cancer treatment – are also at risk of illness from infection via pet cats or uncooked meat. <h2>Then there are tapeworms and amoebas</h2> Tapeworms can infect different parts of the body including the brain. This is called <a href="https://www.cdc.gov/parasites/resources/pdf/npis_in_us_neurocysticercosis.pdf">neurocysticercosis</a> and is the leading cause of epilepsy worldwide. Neurocysticercosis is uncommon in the Western world and infection is usually via eating pork that is uncooked or prepared by someone who is infected with tapeworm (Taenia solium). It is more likely in locations where pigs have contact with human faeces via sewerage or waterways. <figure class="align-right zoomable"><figcaption></figcaption></figure> Tapeworm larvae can infect muscle and soft tissue. Brain tissue can provide a home for larvae because it is soft and easy to get to via blood vessels. Brain infection can cause headaches, dizziness, seizures, cognitive impairment and even dementia, due to an increase in <a href="https://www.cdc.gov/parasites/cysticercosis/gen_info/faqs.html">cerebral spinal fluid pressure</a>. <a href="https://www.cdc.gov/parasites/naegleria/general.html">Naegleria fowleri</a> is an amoeba found in lakes, rivers and springs in warm climates including <a href="https://www.sahealth.sa.gov.au/wps/wcm/connect/public+content/sa+health+internet/public+health/water+quality/naegleria+fowleri#:%7E:text=How%20common%20are%20Naegleria%20fowleri,frequently%20found%20in%20the%20environment.">in Australia</a>. People swimming in infected waters can have the parasite enter their body through the nose. It then travels to the brain and destroys brain tissue. The condition is <a href="https://www.cdc.gov/parasites/naegleria/general.html#:%7E:text=Top%20of%20Page-,What%20is%20the%20death%20rate%20for%20an%20infected%20person%20who,States%20from%201962%20to%202022.">almost always fatal</a>. <h2>Yikes! 4 ways to avoid parasitic infection</h2> That all sounds very scary. And we know being infected by a snake parasite is very rare – finding one alive in someone’s brain is even rarer. But parasites are all around us. To minimise your risk of infection you can: 1. avoid undercooked or raw pork. Freezing meat first may reduce risks (though home freezers <a href="https://www.cdc.gov/parasites/trichinellosis/prevent.html">may not get cold enough</a>) and it must be cooked to a <a href="https://www.sciencedirect.com/science/article/pii/S0924224418301560#:%7E:text=and%20time%20conditions.-,Cooking%20at%20core%20temperature%2060%E2%80%9375%20%C2%B0C%20for%2015,relied%20upon%20in%20home%20situations.">high internal temperature</a>. Avoid pork if you are travelling in places with poor sanitation 2. avoid jumping or diving into warm fresh bodies of water, especially if they are known to carry Naegleria fowleri. Although only a <a href="https://www.cdc.gov/parasites/naegleria/graphs.html">handful of cases</a> are reported each year, you should assume it’s present 3. practise good <a href="https://www.cdc.gov/handwashing/when-how-handwashing.html#:%7E:text=Follow%20Five%20Steps%20to%20Wash%20Your%20Hands%20the%20Right%20Way&text=Wet%20your%20hands%20with%20clean,for%20at%20least%2020%20seconds.">hand hygiene</a> to reduce the risk of rare and common infections. That means washing hands thoroughly and often, using soap, scrubbing for at least 20 seconds, rinsing and drying well. Clip and clean under fingernails regularly 4. to avoid soil-borne parasites wear shoes outside, especially in rural and remote regions, wash shoes and leave them outside.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/212437/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/vincent-ho-141549">Vincent Ho</a>, Associate Professor and clinical academic gastroenterologist, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Image credits: Canberra Health This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Facebook Messenger scams are on the rise – here’s how to protect yourself

Facebook Messenger scams prey on our vulnerabilities Scams through Facebook’s Messenger platform are being reported at higher rates than ever before, according to AARP, citing its own data as well as that of the government. Since Facebook’s early days, cybercriminals have been mining Facebook’s direct-messaging capabilities to scam unsuspecting victims out of money. One of the earliest Facebook Messenger scams involved a message, purportedly from a friend, claiming they were stuck in a foreign country and in desperate need of immediate financial assistance to get out. It wasn’t really the friend, however, but rather a scammer who had hacked into the friend’s account. Imposter scams such as “the friend in a foreign country” have evolved and proliferated over the years. The common thread is the scammer either creates an account impersonating an actual Facebook account or hacks into an existing Facebook account. In either case, the scammer then uses the fake/hacked account to send private messages to the account holder’s friends that elicit either money or personal information. The messages vary, but all are designed to prey on our human vulnerabilities, including: <ul> <li>the desire to be a “hero”</li> <li>the desire to appear “generous”</li> <li>the desire to win “free money”</li> <li>the desire to be loved and admired</li> <li>the desire to avoid shame or punishment</li> </ul> If a scammer tries to message you, report them, Facebook advises, but that begs the larger question of how does one recognise a Facebook Messenger scam? Current Messenger Facebook scams According to Facebook and our cybersecurity experts, here are the most common Facebook Messenger scams today: Romance scams. Preying on our desire to be loved and admired, romance scammers appear as attractive strangers with sad stories and a desire to love and be loved. The most effective romance scammers will friend a number of mutual friends before reaching out to any of them, in an attempt to make themselves seem less like strangers and more like people in the same social network. Many use photos they’ve stolen off the Internet and many pose as members of the military or as doctors, in an attempt to inspire trust, admiration, and even authority. What they all have in common is they can’t meet you just yet because they’re somewhere far away, and although it may take a bit of time, even as much as several weeks, they will eventually ask you to send money so that they can come to see you. Lottery scams. Preying on our desire for “free money,” lottery scammers appear as friends or organisations who are thrilled to tell you you’ve won money in some lottery or contest. The common thread? It’s a contest you have no recollection of having entered and to get the prize, you’ll have to either pay a fee or “refundable” advance or provide personal information. Inheritance scams. Also preying on our desire for free money, inheritance scammers claim to be lawyers or others who represent someone who has died and supposedly left you their estate or some portion of it – but first, you’ll have to fork over some money or personal information. Loan scams. Another variation on the “free money” theme is the loan scam, whereby the scammer promises low-interest loans with no money down – except for a “refundable” application fee. Facebook points out that loan scammers may send messages via Messenger and also leave posts and comments on Pages and in Groups to legitimise themselves. However, legitimate lenders wouldn’t offer loans via Facebook Messenger, nor would they ask you for money to proceed with a loan application. Donation scams. Facebook specifically warns users to watch out for “famous people” or people claiming to represent a charity hitting them up for a donation. Donation scams, which are easy money for a scammer because they are a direct request for payment, prey on our desire to be perceived, or to perceive ourselves, as generous. “Hey, is this you?” scams. Consumer Affairs warns of this “phishing scam” that uses the threat of shame to goad you into giving up personal information. The scammer hacks into one of your Facebook friend’s Messenger accounts and sends you a video, asking if it’s really you in the video, and implying there’s something in the video that could embarrass you. If you ever get a message like this, Consumer Affairs urges you to ignore and delete it to avoid giving away personal information or introducing a virus onto your computer. Red flags to watch out for Unfortunately, Facebook Messenger scams evolve rapidly (as soon as we suss them out, there are several more to replace them). So, it’s a good idea to be aware of these warning signs that we culled from our experts: Someone is asking you for money. While Facebook warns specifically against strangers asking for money, Rachel Wilson, investigative coordinator for The Smith Investigation Agency, points out to Reader’s Digest that any time anyone asks you for money over Messenger, it’s immediately suspect. “If friends or family ask you to help them in an emergency, always call to speak with them personally to confirm that the message originated with them.” Someone is getting a little too personal. When someone sends you a message requesting personal information, especially financial information, it should be considered suspicious, advises Sean Messier, credit industry analyst for Credit Card Insider. Messier suggests not revealing any such information until you’re certain the message-sender is who they claim to be, but it’s probably also a good idea to never reveal any such information over Messenger at all. Someone is offering something for free. You know how they say there’s no such thing as a free lunch? Well, there’s no such thing as free money on Facebook, points out Robert Siciliano, security expert. This is true for any kind of “free money” Messenger message, including those involving lotteries, loans, contest winnings, inheritances, lost bank accounts, and reimbursements of money owed. Someone who wants to take the conversation off Facebook (to text or email, etc). Facebook warns against taking conversations off Facebook unless you’re absolutely certain, beyond a shadow of a doubt, the message sender is who they say they are. Messages that seem out of character for the sender. If a message seems “out of the norm” for the sender, trust your instincts and ignore it. This is doubly true if the message includes an attachment. Be very wary of opening attachments in general, and particularly if something seems “off” about the message or the sender. Messages rife with spelling and grammatical errors. Facebook points out that when a message is filled with typos and grammatical errors, you should have your guard up. A single typo is one thing, but things like the misspelling of names and places are a big red flag. Messages from new accounts with few friends. Roger Thompson, CEO of Thompson Cybersecurity Labs, points out that new accounts with few friends should always be considered suspicious until confirmed otherwise. Friend requests from such accounts and from duplicate friend accounts should be considered suspect as well. To avoid getting hacked (and used by a cybercriminal in an imposter scam), Wilson recommends updating your social media passwords regularly and always use two-factor authentication. She also notes that with Facebook use increasing among seniors, it would be a good deed to speak to older family members about Messenger scams and how to avoid them.

Marine species are being pushed towards the poles. From dugong to octopuses, here are 8 marine species you might spot in new places

<a href="https://theconversation.com/profiles/gretta-pecl-128477">Gretta Pecl</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>; <a href="https://theconversation.com/profiles/curtis-champion-1373045">Curtis Champion</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a>, and <a href="https://theconversation.com/profiles/zoe-doubleday-393169">Zoe Doubleday</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> If you take a plunge in the sea this winter, you might notice it’s warmer than you expect. And if you’re fishing off Sydney and catch a tropical coral trout, you might wonder what’s going on. The reason is simple: hotter water. The ocean has absorbed the vast majority of the extra heat trapped by carbon dioxide and other greenhouses gases. It’s no wonder heat in the oceans is building up rapidly – and this year is <a href="https://theconversation.com/ocean-heat-is-off-the-charts-heres-what-that-means-for-humans-and-ecosystems-around-the-world-207902">off the charts</a>. That’s even without the likely arrival of El Niño, where the Pacific Ocean gets warmer than usual and affects weather all over the world. Our coastal waters <a href="http://www.bom.gov.au/oceanography/oceantemp/sst-outlook-map.shtml">are forecast</a> to be especially warm over the coming months, up to 2.5℃ warmer than usual in many places. <figure class="align-center "><img src="https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=482&fit=crop&dpr=1 600w, https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=482&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=482&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=605&fit=crop&dpr=1 754w, https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=605&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/533327/original/file-20230622-27-cqb9j1.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=605&fit=crop&dpr=3 2262w" alt="" /><figcaption>Oceans around Australia are forecast to be much warmer than usual. SSTA stands for projected Sea Surface Temperature Anomaly, the difference between forecast ocean temperatures and a historical baseline period encompassing 1990–2012. Bureau of Meteorology</figcaption></figure> Many marine species live within a narrow temperature range. If the water heats up, they have to move, and if they don’t, they might die. So those that can move, are moving. In Australia, at least 200 marine species have <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.15634">shifted distributions</a> since 2003, with 87% heading south. This pattern is happening all around the world, both on land and <a href="https://theconversation.com/thousands-of-photos-captured-by-everyday-australians-reveal-the-secrets-of-our-marine-life-as-oceans-warm-189231">in the ocean</a>. This year, the warmer ocean temperatures during winter mean Australia’s seascapes are likely to be more like summer. So, the next time you go fishing or diving or beachcombing, keep your eyes peeled and your camera ready. You may glimpse the enormous disruption happening underwater for yourself. <h2>Here are eight species on the move</h2> 1. Moorish idol (Zanclus cornutus) Historic range: northern Australia Now: This <a href="https://www.redmap.org.au/species/1/204/">striking fish</a> can now be seen south of Geraldton in Western Australia and Eden in New South Wales. This is a great fish for divers to spot on hard-bottomed habitats. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/533373/original/file-20230622-21-6g6xk8.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="moorish idol" /></a><figcaption>Moorish Idols are heading south to escape the heat. Shutterstock</figcaption></figure> 2. Branching coral (Pocillopora aliciae) Historic range: northern NSW Now: Look out for this <a href="https://www.redmap.org.au/species/2/255">pale pink beauty</a> south of Port Stephens, not far from Sydney. Seemingly immovable species like coral are fleeing the heat too. They’re already providing habitat for a range of other shifting species like tropical fish and crab species. 3. Eastern rock lobster (Sagmariasus verreauxi) Historic range: common in NSW Now: South, as far as <a href="https://www.redmap.org.au/species/2/167">it can get.</a> It’s now found in Tasmania and even in <a href="https://www.cambridge.org/core/journals/journal-of-the-marine-biological-association-of-the-united-kingdom/article/westward-range-expansion-of-the-eastern-rock-lobster-sagmariasus-verreauxi-in-australia/8DE945E58E1DDA1A2BB7431065AAC8EC">South Australia</a>. This tasty greenish crustacean <a href="https://www.int-res.com/abstracts/meps/v624/p1-11/">doesn’t like heat</a> and has moved south into the territory of red southern rock lobsters (Jasus edwardsii). 4. Gloomy octopus (Octopus tetricus) Previous range: common in NSW Now: As far south as Tasmania. Look out for this slippery, smart invertebrate in <a href="https://www.redmap.org.au/species/2/127">Tasmanian waters</a> this winter. You might even spot the octopus nestled down with some eggs, as this looks to be a <a href="https://www.publish.csiro.au/mf/mf14126">permanent sea change</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=462&fit=crop&dpr=1 600w, https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=462&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=462&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=581&fit=crop&dpr=1 754w, https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=581&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/533376/original/file-20230622-17-lf2y8r.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=581&fit=crop&dpr=3 2262w" alt="gloomy octopus" /></a><figcaption>The gloomy octopus is also known as the common Sydney octopus. Niki Hubbard, Wikimedia, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> 5. Whitetip reef shark (Triaenodon obesus) Previous range: northern Australia Now: <a href="https://www.redmap.org.au/species/3/185">South of K'gari</a> (formerly known as Fraser Island). Classed as vulnerable in parts of the world, this tropical shark is a slow swimmer and never sleeps. It poses very little danger to humans. 6. Dugongs (Dugong dugon) Previous range: northern Australia Now: As far south as Shark Bay in WA and <a href="https://www.abc.net.au/news/2023-05-17/tweed-river-dugong-sighting-boaties-warned/102355438">Tweed River</a> in New South Wales. Our waters are home to the largest number of dugong in the world. But as waters warm, they’re heading south. That means more of us may see these elusive sea-cows as they graze on seagrass meadows. Some of the most adventurous have gone way out of their normal range – in 2014, a kitesurfer <a href="https://www.redmap.org.au/articles/2021/07/26/are-dugongs-hitching-a-ride-south/">reported</a> passing a dugong at City Beach, Perth. As a WA wildlife expert says, dugongs may occasionally stray further south of Shark Bay but “given the recent warming trend […] more dugong sightings might be expected in the future” 7. Red emperor (Lutjanus sebae) and other warm water game fish Previous range: northern Australia Now: Appearing much further south – especially in WA. Look for <a href="https://www.redmap.org.au/species/1/108/">red</a>, threadfin, and redthroat emperors in southwest WA as the Leeuwin current carries these <a href="https://www.redmap.org.au/articles/2021/07/26/game-fish-follow-warm-route-south/">warm water species</a> south. As WA fisheries expert Gary Jackson has said, this current is a warming hotspot, acting like a warm water highway for certain marine species. These fish are highly <a href="https://goodfish.org.au/species/red-emperor/">sought after</a> by fishers. 8. Long-spined sea urchin (Centrostephanus rodgersii) Historic range: NSW and Victoria Now: Tasmania Look out for these <a href="https://www.redmap.org.au/species/2/34/">spiky critters</a> in southern and western Tasmania. The larvae of these urchins have crossed the Bass Strait and found a new home, due to warming waters. Urchins are grazers and can scrape rocks clean, creating urchin barrens where nothing grows. That’s bad news for kelp forests and the species which depend on them. In response, Tasmanian authorities are working to create a <a href="https://fishing.tas.gov.au/community/long-spined-sea-urchin-management/long-spined-sea-urchin-strategy#:%7E:text=%E2%80%8B%E2%80%8B%E2%80%8BTackling%20the%20longspined%20sea%20urchin&text=Unchecked%2C%20the%20urchin's%20presence%20is,at%20around%2020%20million%20individuals.">viable urchin fishery</a> to keep numbers down. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=400&fit=crop&dpr=1 600w, https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=400&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=400&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=503&fit=crop&dpr=1 754w, https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=503&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/533379/original/file-20230622-33216-7lslyr.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=503&fit=crop&dpr=3 2262w" alt="long spined sea urchins" /></a><figcaption>Long-spiked sea urchins are voracious eaters of seaweed. <a class="source" href="https://www.flickr.com/photos/johnwturnbull/32131133496/in/photostream/">John Turnbull/Flickr</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> <h2>You can help keep watch</h2> For years, fishers, snorkellers, spearfishers and the general public have contributed their unusual marine sightings to <a href="https://www.redmap.org.au/">Redmap</a>, the Australian citizen science project aimed at mapping range extensions of species. If you spot a creature that wouldn’t normally live in the waters near you, you can upload a photo to log your sighting. For example, avid spearfisher Derrick Cruz logged a <a href="https://www.redmap.org.au/sightings/1624/">startling discovery</a> with Redmap in 2015: A coral trout in Sydney’s waters. As he told us: “I’ve seen plenty of coral trout in tropical waters, where they’re at home within the coral. But it was surreal to see one swimming through a kelp forest in the local waters off Sydney, much further south than I’ve ever seen that species before!” How does tracking these movements help scientists? Many hands make light work. These vital observations from citizen scientists <a href="https://data-blog.gbif.org/post/gbif-citizen-science-data">have helped</a> researchers gain deeper understanding of what climate change is doing to the natural world in many places, from bird migrations to flowering plants to marine creatures. So, please keep an eye out this year. The heat is on in our oceans, and that can mean sudden change. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/207115/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gretta-pecl-128477">Gretta Pecl</a>, Professor, ARC Future Fellow & Director of the Centre for Marine Socioecology, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a>; <a href="https://theconversation.com/profiles/curtis-champion-1373045">Curtis Champion</a>, Research Scientist, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a>, and <a href="https://theconversation.com/profiles/zoe-doubleday-393169">Zoe Doubleday</a>, Marine Ecologist and ARC Future Fellow, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Friendships may help protect women from health conditions in older age

Human connection may, in fact, help protect women from chronic health conditions in older age, according to a Queensland-led study. The University of Queensland researchers tracked more than 7,600 Australian women aged between 45 and 50 for two decades as part of the Australian Longitudinal Study on Women's Health. The study went as follows: Every three years, women filled out a questionnaire, rating their levels of satisfaction with a range of relationships, including partners, family, friends, work colleagues and any other social connections. Data also collected if they had been diagnosed with two or more of 11 chronic health conditions. <ul> <li dir="ltr" role="presentation">High blood pressure</li> <li dir="ltr" role="presentation">Heart disease</li> <li dir="ltr" role="presentation">Stroke </li> <li dir="ltr" role="presentation">Chronic obstructive pulmonary disease </li> <li dir="ltr" role="presentation">Asthma </li> <li dir="ltr" role="presentation">Arthritis</li> <li dir="ltr" role="presentation">Cancer</li> <li dir="ltr" role="presentation">Depression</li> <li dir="ltr" role="presentation">Anxiety </li> <li dir="ltr" role="presentation">Osteoporosis</li> <li dir="ltr" role="presentation">Diabetes</li> </ul> The researchers found 58.3 per cent of the women had developed more than one chronic disease during the 20 years of monitoring, from 1996 to 2016. Those with the lowest relationship satisfaction scores had the highest odds of having multiple chronic diseases. So, make friends and keep them around because it may just prevent a serious illness.

Calls to protect rights of tenants with animals

Amid the current cost-of-living crisis and housing crisis, renters across Australia and New Zealand are finding it harder to secure homes to rent - but it’s even harder for renters with pets. In parts of Australia, landlords are legally protected if they refuse applications from tenants with companion animals, while New Zealand rentals can still refuse to have pets as well. Dr Zoei Sutton, an academic at Flinders University in South Australia, conducted a study involving in-depth interviews with tenants and stakeholders, including landlords, and found that many were struggling to obtain a rental when they had pets. “My study shows Australian landlords and property managers are particularly reluctant to house cats, as they’re seen as leaving allergy hazards or the need for deep cleaning of carpets. Owners of bigger dogs and certain breeds can also have a harder time finding housing,” she said. “And while we’re starting to see legislative shifts in Victoria and NSW, legislation to protect pet owners has been defeated in South Australia.” During the interviews, Dr Sutton also uncovered several strategies renters could use to improve their chances of success, including preparing pet ‘resumes’ for agents and landlords. “Both tenants and stakeholders agreed that there needs to be an understanding that rental houses are homes. This means working with both landlords and tenants to make sure everyone has a clear understanding of what fair ‘wear and tear’ is,” she added. While interviewing tenants, landlords, real estate agents, and emergency housing organisations in SA, she heard multiple stories of renters experiencing a “constant source of worry” while renting. “One tenant reported finding just ten potential properties listed as pet friendly while another family found only two within their price range. Some tenants are being asked to pay higher rent to secure a house,” Dr Sutton said. “Multiple participants reported that there was a bidding war for houses with some tenants offering 3 or 6 months rent in advance, just to secure a house. “One family had fallen through the damaged floor of their house multiple times but were reluctant to report the landlord’s failure to maintain the home because this might result in a bad reference when they next had to move.” “It’s a constant source of worry, knowing that your lease might not be renewed or your house might be sold and you’ll have to try to find something again.” Meanwhile, New Zealand journalist Charlotte Muru-Lanning <a href="https://thespinoff.co.nz/society/28-09-2022/the-absence-of-rights-for-renters-with-pets-is-just-cruel" target="_blank" rel="noopener">reported</a> in September that 14 percent of rentals available across the country were listed as “pets OK”, despite nearly half of New Zealand households. “We need more protections for tenants so they can report unfair housing conditions without jeopardising future housing,” Sutton said. “Animals need to be able to use the home too, and there are small things you can do to minimise any potential damage. “Property managers have a key role in educating landlords and tenants to ensure everyone is happy and has reasonable expectations.” Image: Getty Images

Banksy: who should foot the bill to protect his work in public spaces?

When a mural by artist Banksy <a href="https://www.bbc.co.uk/news/uk-wales-46617742">appeared on a garage wall</a> in Port Talbot, the building’s owner, Ian Lewis, had no idea just <a href="https://www.bbc.co.uk/news/uk-wales-46771722">how many people</a> would want to get a good look at it. The mural has attracted <a href="https://www.bbc.co.uk/news/uk-wales-46759349">thousands of visitors</a> and Lewis has been keen to <a href="https://www.bbc.co.uk/news/uk-wales-46617742">protect it</a>, by employing guards, and building a see-through covering over the work. But should there even be security on a piece of graffiti? After all, <a href="https://hyperallergic.com/38778/occupying-the-walls-graffiti-as-political-protest/">the essence of graffiti</a> is that it is temporary and subject to the possibility of being covered over with the next slogan or image. It has long been one of the means by which people can <a href="https://www.theguardian.com/cities/gallery/2017/may/17/writing-wall-political-graffiti-banksy-brexit-trump-in-pictures">make their views known</a> in a very public way without official sanction. It is a form of protest that visually takes up public space and asks for no endorsement and often no individual credit. The list of graffiti artists who have gained recognition in the contemporary art world is not a long one. Shepherd Fairey, who <a href="https://www.artic.edu/artworks/229396/barack-obama-hope-poster">designed the Obama “Hope” poster</a>, and <a href="https://www.theartstory.org/artist-basquiat-jean-michel.htm">Jean Michel Basquiat</a> are two of the most well known. Banksy himself has been quoted as saying that he never craved commercial success and that it’s actually <a href="https://www.villagevoice.com/2013/10/09/village-voice-exclusive-an-interview-with-banksy-street-art-cult-hero-international-man-of-mystery/">a mark of failure for a graffiti artist</a>. A lofty sentiment, but whether he wants it or not, the popularity of Banksy’s work is phenomenal. The pared down stencil style coupled with often highly astute political commentary and visual puns is easy to read. It is enough to satisfy even those for whom art should consist of a “proper picture of something”. It also lends itself very well to reproduction and copying. I actually have a mug emblazoned with Banksy style rats sitting on my desk as I write. This is what happens when an iconoclast becomes an icon. What started out as a practice that deliberately subverted the concept of art as an exclusive, costly investment, has now become just as commodified as the latest piece by <a href="https://www.theartstory.org/artist-hirst-damien.htm">Damien Hirst</a>. <h2>Banksy’s bankability</h2> I’m personally on the fence about some of Banksy’s more recent work. I’m completely on board with the political nature of the imagery and most definitely share a lot of his ideological sentiments, but there is a degree to which he is becoming a parody of himself. For example, while it’s easy to appreciate the point he was making with the recently auctioned self-destructing drawing “<a href="https://theconversation.com/banksy-i-was-in-the-room-when-his-painting-shredded-and-enhanced-his-brand-104660">Love is in the Bin</a>”, no one could convince me that he was unaware of the effect that the action would have on his bankability. Given he knows the impact his work can have, was it selfish of Banksy to impose this latest piece on the unsuspecting garage owner? Or was it an act of extreme philanthropy, bestowing on Port Talbot a gift that can be used either to benefit the individual or the community? He must have known that Lewis would be plagued with attention, and the inevitability of this imposed cultural responsibility must surely have at least crossed Banksy’s mind. Public art comes in many diverse forms, from the monumental statues commemorating historical figures, to the temporary and often illegal murals created by contemporary graffiti artists. My own practice is informed by an ethos of inclusion that places the nearby community at the centre of decisions about how it is created, themed and managed. Because of that philosophical background, I do find Banksy’s imposition of his work without regard for its effect on the local community to be irritatingly entitled. However, the <a href="https://www.theartstory.org/artist-banksy-artworks.htm">issues he highlights</a> such as the <a href="https://theartstack.com/artist/banksy/i-remember-when-all-this-was-trees">capitalist obsession with growth</a> over sustainability, and <a href="https://www.independent.co.uk/voices/banksy-port-talbot-graffiti-wales-michael-sheen-steel-pollution-environment-a8692821.html">industrial air pollution</a> are relevant and important to a much wider community, so I appreciate that by using his fame to draw attention to them he is carrying out a form of community service. The Welsh government <a href="https://www.walesonline.co.uk/news/wales-news/banksy-collector-willing-pay-six-15656998">has since confirmed</a> it will be taking over security for the Port Talbot artwork, and is discussing the future of the piece. Whether by design or because he just isn’t interested in how the work is used, it’s part of Banksy’s artistic practice to leave the work to the mercy of others when it’s complete. However, it could be argued that he could have used <a href="https://www.artspace.com/magazine/art_101/close_look/how-does-banksy-make-money-or-a-lesson-in-art-market-economics-55352">some of his own money</a> to help protect the work, and mitigate against any grief <a href="https://www.bbc.co.uk/news/uk-wales-46810787">he’s caused the garage owner</a>. I’d personally like to see the work sold, and the proceeds used to address some of the social and political issues that Banksy highlights with his work. It worked for Dennis Stinchcombe who, when a mural entitled Mobile Lovers appeared on the doorway of his Bristol youth club in 2014, sold the work and used the funds <a href="https://www.bbc.co.uk/news/uk-wales-46810787">to save the struggling organisation</a>. Whatever happens now, one thing is certain: Banksy certainly knows how to get his work in the news.

Do tenancy reforms to protect renters cause landlords to exit the market?

More Australians are <a href="https://theconversation.com/wealthy-landlords-and-more-sharehousing-how-the-rental-sector-is-changing-94394">renting their housing longer</a> than in the past. But they have relatively little legal security against rent increases and evictions compared to <a href="https://theconversation.com/what-australia-can-learn-from-overseas-about-the-future-of-rental-housing-90401">tenants in other countries</a>. When state governments suggest stronger protections for tenants, landlords and real estate agents <a href="https://www.reiq.com/articles/reiq-concerned-rental-reforms-unravel-rights-of-property-owners/">claim it will cause disinvestment</a> from the sector, increasing pressure on already tight rental markets. In <a href="https://www.ahuri.edu.au/research/final-reports/391">research</a> for the Australian Housing and Urban Research Institute (<a href="https://www.ahuri.edu.au/about">AHURI</a>), published today, we put the “disinvestment” claim to the test. We looked at the impacts of tenancy reforms in New South Wales and Victoria on rental property records over 20 years, as well as surveying hundreds of property investors. We found no evidence to support this claim. We did find a high rate of turnover as properties enter and leave the sector. This happened regardless of tenancy law reforms. It’s a major cause of the unsettled nature of private rental housing for tenants. We suggest that if substantial tenancy reforms did cause less committed landlords to exit the sector, that might not be a bad thing. <blockquote class="twitter-tweet"> A tenancy law expert says it could be illegal in several states, while tenants’ advocates say it preys on vulnerable renters during Australia’s housing crisis. <a href="https://t.co/hQEdS80a3h">https://t.co/hQEdS80a3h</a> (via <a href="https://twitter.com/abcnews?ref_src=twsrc%5Etfw">@abcnews</a>) — ABC Australia (@ABCaustralia) <a href="https://twitter.com/ABCaustralia/status/1587927668846399488?ref_src=twsrc%5Etfw">November 2, 2022</a></blockquote> How did we test the disinvestment claim? We analysed records of all rental bond lodgements and refunds in Sydney and Melbourne from 2000 to 2020. From these records we can see properties entering the rental sector for the first time (investment) and exiting the sector (disinvestment). We looked for changes in trends in property entries and exits around two law reform episodes: when the 2010 NSW Residential Tenancies Act took effect, and the start of a tenancy law reform review in Victoria in 2015. We found no evidence the NSW reforms affected property entries (investment). And property exits (disinvestment) were slightly reduced – that is, fewer properties exited than expected. In Victoria, we found property entries reduced slightly when the law reform review started – perhaps a sign of investors pausing for “due diligence”. We saw no effect on property exits. So in neither state did we find evidence of a disinvestment effect. We also surveyed 970 current and previous property investors, and got a similar picture. When deciding to invest, investors said prospective rental income and capital gains were the most important considerations, but tenancy laws were important too. On the other hand, tenancy laws were the least-cited reason for disposing of properties. Many more investors said they did it because they judged it a good time to sell and realise gains, or they wanted money for other purposes, or because the investment was not paying as they had hoped. A state of constant churn Our research also gives new insights into the private rental sector, which <a href="https://www.housingdata.gov.au/">has been growing</a> relative to owner-occupied and social housing. Small-holding “mum and dad” landlords dominate the sector. Some 70% of landlords own a single property. Multiple-property owners own more properties in total, but still relatively small numbers (rarely more than ten) compared to corporate landlords in other countries who have tens of thousands of properties, or even more. Australia now has some large corporate landlords, but their properties are a tiny fraction of the total rental stock. Beneath its gradual growth and persistent small-holding pattern, the private rental sector is dynamic. Properties enter and exit the sector very frequently. In both Sydney and Melbourne, our analysis shows, most properties exit within five years of entering. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=307&fit=crop&dpr=1 600w, https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=307&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=307&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=385&fit=crop&dpr=1 754w, https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=385&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/496048/original/file-20221118-13-8fazlx.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=385&fit=crop&dpr=3 2262w" alt="Chart showing private rental properties, Sydney and Melbourne, 2000–20, by year of first observation in rental bonds data and at five-year intervals" /></a><figcaption>Numbers of private rental properties in Sydney and Melbourne at five-year intervals from 2000 to 2020. Properties are categorised by year of first observation in rental bonds data. The authors</figcaption></figure> More than 30% of tenancies begin in a property that’s new to the rental sector. And more than 25% of tenancy terminations happen when the property exits the sector. Our investor survey also shows the sector’s dynamism. Many investors made repeated investments, owning multiple properties and some interstate. They indicated strong interest in <a href="https://theconversation.com/ever-wondered-how-many-airbnbs-australia-has-and-where-they-all-are-we-have-the-answers-129003">short-term letting</a>, such as Airbnb, and significant minorities had used their properties for purposes other than rental housing. Australia’s rental housing interacts closely with other sectors, particularly owner-occupied housing, as houses and strata-titled apartments trade between the sectors. The tax-subsidised property prices paid by owner-occupiers heavily influence investors’ gains and decision-making. Rental is also increasingly integrated with tourism, through governments’ <a href="https://theconversation.com/who-wins-and-who-loses-when-platforms-like-airbnb-disrupt-housing-and-how-do-you-regulate-it-106234">permissive approach to short-term letting</a>. In short, the Australian rental sector is built for investing and disinvesting. As properties churn in and out of rental, renters are churned in and out of housing. This presents problems for tenants. A new agenda for tenancy law reform Australian residential tenancies law has accommodated the long-term growth of the rental sector and its dynamic character. With no licensing or training requirements, it’s easy for landlords to enter the sector. It’s also easy to exit by terminating tenancies, on grounds they want to use a property for other purposes, or even without grounds in many cases. Over the years tenancy law reform has fixed some problem areas, but with virtually no national co-ordination. Laws are increasingly inconsistent on important topics, such as tenants’ security (for example, some states have restricted, but not eliminated, no-grounds terminations), minimum standards and domestic violence. Reforms have overlooked significant problem areas, such as steep rent increases and landlords’ liability for defective premises. <blockquote class="twitter-tweet"> Works for Australia too. Although don't even need to pretend to put it on the market in NSW, it's called a "no grounds eviction" or perhaps more accurately: "tenant expected a liveable home or repairs to broken stuff". <a href="https://t.co/GolGDqlyCu">https://t.co/GolGDqlyCu</a> <a href="https://t.co/wORI3K6Yap">pic.twitter.com/wORI3K6Yap</a> — Nathan Lee (@NathanLee) <a href="https://twitter.com/NathanLee/status/1542298797039964160?ref_src=twsrc%5Etfw">June 30, 2022</a></blockquote> It is time to pursue a national agenda that goes further than previous limited reforms. The focus should be on the rights of tenants to affordable housing, in decent condition, that supports autonomy and secure occupancy. Where landlords say it is too difficult and they will disinvest, this should not be taken as a threat. Indeed, it would be a good thing if the speculative, incapable and unwilling investors exited the sector. This would make properties available for new owner-occupiers and open up prospects for other, more committed landlords, especially non-profit providers of rental housing. Similarly, if we had higher standards and expectations to discourage private landlords from entering the sector, that would open up scope for new owner-occupiers and investors who are less inclined to churn properties and households. While past tenancy law reforms have not caused disinvestment, maybe the next reforms should. <hr /> The authors acknowledge the contributions of their research co-authors, Professor Kath Hulse, Professor Eileen O’Brien Webb, Dr Laura Crommelin and Liss Ralston.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/194900/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> Writen by Chris Martin, Milad Ghasri, Sharon Parkinson and Zoe Goodall.

“She could’ve been protected that day”: Gabby Petito’s family files lawsuit

The family of Gabby Petito, whose boyfriend admitted to killing her last year, have launched a wrongful death suit against Utah’s Moab Police Department, claiming officers’ negligence led to her death. Ms Petito and her boyfriend Brian Laundrie were stopped by officers in Moab last year after a bystander allegedly saw Mr Laundrie hit Ms Petito and reported the incident to police. The couple were ultimately not cited for domestic violence, and Ms Petito’s body was found weeks later after she had been strangled. On Thursday local time, Ms Petito’s parents and other family members announced their intent to sue the department for $US 50 million ($NZ 85 million). The suit claims that police officers failed to effectively intervene in a domestic violence situation between Ms Petito and Mr Laundrie by failing to issue a domestic violence citation, claiming that officers disregarded signs of violence they should have been trained to notice. “She could’ve been protected that day,” Nicole Schmidt, Ms Petito’s mother, said. The suit also claims that police officers “coached Gabby to provide answers that the officers used to justify their decision not to enforce Utah law", with the family claiming that officers “egregiously misinterpreted Gabby’s extreme emotional distress, seeing it as the cause of the domestic violence rather than its result”, per AP. “Despite the witness’s report, the officers treated Brian as if he were the victim of domestic abuse rather than the perpetrator,” the lawsuit reads, per Fox News. “In fact, the officers never directly questioned Brian about whether he hit Gabby or how she ended up with scratches on her face. “The purpose of this lawsuit is to honour Gabby’s legacy by demanding accountability and working for change in the system to protect victims of domestic abuse and violence and to prevent such tragedies in the future.” Moab police officer Eric Pratt is also alleged to have been “fundamentally biased” in his investigation by “choosing to believe Gabby's abuser, ignoring evidence that Gabby was the victim and intentionally looking for loopholes to get around the requirements of Utah law and his duty to protect Gabby", The family’s complaint is based on the claim of an unnamed woman referred to as “Witness 1”, who alleged that Officer Pratt threatened to kill her after their relationship ended while he was the police chief in the rural town of Salina, Utah. In a statement after the lawsuit was filed, the city of Moab said Ms Petito’s death was tragic but not the fault of the police department. "Our officers acted with kindness, respect and empathy toward Ms Petito," city spokesperson Lisa Adams said. "No one could have predicted the tragedy that would occur weeks later and hundreds of miles away, and the City of Moab will ardently defend against this lawsuit." In a statement, the Moab Police Department said the 22-year-old’s death was a “terrible tragedy” that no-one could have predicted. “The death of Gabrielle Petito in Wyoming is a terrible tragedy, and we feel profound sympathy for the Petito and Schmidt families and the painful loss they have endured,” it read. “The death of Gabrielle Petito in Wyoming is a terrible tragedy, and we feel profound sympathy for the Petito and Schmidt families and the painful loss they have endured. “The attorneys for the Petito family seem to suggest that somehow our officers could see into the future based on this single interaction. “In truth, on August 12, no one could have predicted the tragedy that would occur weeks later and hundreds of miles away, and the City of Moab will ardently defend against this lawsuit.” The suit comes after a notice of claim was filed in August, and after an independent investigation found that police made “several unintentional mistakes”, including not issuing a domestic violence citation, in January.
