Woman slammed for using GoFundMe for house deposit

<p>A woman has been relentlessly mocked online after launching a GoFundMe page to ask strangers to contribute money to her house deposit. </p> <p>Emmalee Potter, a mother-of-three from Victoria, wrote on the page that she had been "suffering a rough few years" and relying on friends and family for help with accommodation. </p> <p>Now however, Potter is finally in the position where she is tantalising close to being able to purchase her new home after "working hard towards saving", but still finds herself $3,000 short of her goal. </p> <p>As she wrote on the fundraising page, "I'm almost at the final stage but I'm short on the deposit so I'm calling on my village. Please help me get over this last hurdle, every little bit truly helps, a house is more than just a place to live."</p> <p>"It's a foundation for the next chapter of life, a space where memories are made, and where I can really begin to feel settled. Your donation, no matter the size, will go directly toward helping me achieve this dream."</p> <p>While Ms Potter thanked those who could contribute, many were not impressed at her using the platform in order to fund her house. </p> <p>"No hate but you expect people to donate to you so you can buy a house?" one person asked, while another added, "I'm sorry but that is ridiculous. If we are all going to start GoFundMe accounts, I may as well start one so I can go on a holiday to Greece."</p> <p>Another person wrote, "It's a tough time for everyone trying to buy a house, especially with the cost of living, so I'm kind of confused why you're asking for donations. The first paragraph of your listing says 'I'm now in a position to purchase a home' but you're asking strangers to send you money for the deposit?" </p> <p>Ms Potter defended the fundraising page as she responded to one outraged commenter, writing, "It's not about 'funding me a house' it's the small amount still needed to buy something."</p> <p>"Me and my kids are living in a room at my friends. Buying is actually cheaper than renting. We've applied for over 100 rentals and been knocked back. I can get the home loan and pay the repayments [I'm] just needing the last bit of the deposit."</p> <p>Others were quick to defend the woman, as one person wrote, "There's nothing wrong with asking for help."</p> <p><em>Image credits: GoFundMe / Facebook </em></p>

Should you use your retirement savings to pay off debt? Three things to keep in mind

<p><em><a href="https://theconversation.com/profiles/bomikazi-zeka-680577">Bomikazi Zeka</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> and <a href="https://theconversation.com/profiles/jasmine-kinsman-1438670">Jasmine Kinsman</a>, <a href="https://theconversation.com/institutions/nelson-mandela-university-1946">Nelson Mandela University</a></em></p> <p>A host of countries have taken steps to reform the terms under which people can access their retirement benefits. South Africa is the most recent. In 2024 it <a href="https://theconversation.com/south-africa-has-changed-its-retirement-rules-to-help-boost-country-savings-how-it-will-work-233287">introduced changes</a> that allow access to some retirement savings while ensuring that most of the money is still preserved for later.</p> <p>Other countries that have changed the rules to allow members to dip into their savings before retirement include Australia, Chile, India and Portugal. Changes were introduced to ease the financial strain caused by COVID-19 pandemic lockdowns. People across the world are grappling with debt and the cost of living.</p> <p><a href="https://www.treasury.gov.za/comm_media/press/2024/2024%20Two-pot%20System%20Updated%20%20FAQ%20August%202024.pdf">Policymakers</a> have considered this an avenue that offers financially distressed fund members the flexibility to access their retirement funds while still supporting long-term retirement savings. Retirement funds are also often the only sizeable savings that fund members have.</p> <p>A recent report by South Africa’s <a href="https://www.discovery.co.za/portal/business/top-reasons-for-two-pot-withdrawal-requests">Discovery Corporate and Employee Benefits</a>, which represents 3,000 employers that provide pension and provident funds for just over one million employees, found that people aged between 35 and 45 made the most claims to access the savings component of their retirement.</p> <p>When asked what they used the funds for, 24% of members said their withdrawals were for financing home or car expenses. Another 21% of members were using their funds to pay off short-term debt. The majority of members who withdrew their retirement savings were low-income earners (earning up to R125,000 or US$7,000 a year). On the other hand, withdrawals were lowest among high-income earners (earning more than R1 million or US$56,000 a year).</p> <p>This data provides evidence that most low- to middle-income South African consumers are grappling with the trade-off between preserving their capital for retirement and meeting their monthly financial obligations.</p> <p>Given that everyone’s financial situation, goals and needs are different, it’s always best to speak to a financial advisor to assess whether using your retirement savings to pay off debt will be a sound move. But, as academics who have focused on financial planning, we offer three pointers to consider:</p> <ul> <li> <p>understand what you owe, to whom, and what it’s costing you</p> </li> <li> <p>plan beyond paying off debt</p> </li> <li> <p>weigh the pros and cons carefully.</p> </li> </ul> <h2>Know which debt to settle first</h2> <p>Debt with a high interest rate often takes longer to repay, because at the start of the loan repayment period, most of the repayments are going towards interest payments – not reducing the capital amount. If you use your retirement proceeds towards this, it could shorten the period that it would take to settle the loan and reduce the interest repayments, which are compounded according to the outstanding loan balance.</p> <p>Short-term loans, such as those with a repayment term of up to 18 months, tend to have higher interest rates. Unsecured debt, which is debt that is not tied to an asset, also attracts high interest rates because they have little to no collateral requirements. Collateral provides the lender with a guarantee of compensation in the event of default. When there is no collateral, the cost of debt becomes more expensive. Using your retirement proceeds towards settling these short-term loans can free up cash that can be used towards settling other debt and will improve your credit score.</p> <h2>Understanding borrowing behaviour</h2> <p>Using your retirement savings to settle debt should be a priority if you have a plan in place to ensure that your overall financial position will improve. Once the debt is cleared, consider how you can use your free cash in your favour. This could mean boosting your savings or acquiring assets and investments.</p> <p>But if retirement savings are being used to pay off debt while you accumulate more debt, this indicates on ongoing cycle of debt. For example, paying off the minimum amount due on a loan but also consuming the balance that becomes available on the same loan is a sign of poor borrowing behaviour. A more extreme example is taking on more debt to service existing debt.</p> <p>Without a change in borrowing behaviour, using your retirement savings to pay off debt will leave you worse off. You will have missed out on the opportunity to grow your retirement savings and you will have got into more debt.</p> <h2>Debt repayments vs retirement returns</h2> <p>When considering withdrawing from your retirement savings to pay down debt, it’s also important remember this will be at the expense of building your retirement nest egg. For instance, if a 35-year-old were to draw down R30,000 from their retirement fund, that same amount could have grown their retirement capital by over R200,000 by the time they reached 55 years old (assuming an investment return of 10%).</p> <p>Withdrawing your retirement savings on a frequent basis could also mean you may need to work longer and past your intended retirement age to compensate for the withdrawals. Or you may need to find ways to supplement your retirement savings through other investments, or consider reducing your standard of living at retirement.</p> <h2>Is this a sound move?</h2> <p>Remember, withdrawal from retirement savings is subject to tax.</p> <p>While retirement may seem far off when there are more pressing financial needs, using your savings to pay down debt has its advantages and drawbacks. Since withdrawals are being used to pay for expenses and service debt, it’s also important to reflect on borrowing behaviours that may need to be corrected. Otherwise, using retirement savings could become a financial crutch that could make your retirement income less secure.</p> <p>Settling debt using your retirement savings should be done after careful consideration and planning. If in doubt, speak to a financial advisor.<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/244837/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/bomikazi-zeka-680577"><em>Bomikazi Zeka</em></a><em>, Associate Professor in Finance and Financial Planning, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> and <a href="https://theconversation.com/profiles/jasmine-kinsman-1438670">Jasmine Kinsman</a>, Senior Lecturer in Financial Planning and Certified Financial Planner, <a href="https://theconversation.com/institutions/nelson-mandela-university-1946">Nelson Mandela University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Around 3% of us will develop a brain aneurysm in our lives. So what is it and how do you treat it?

<p><em><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/jessica-nealon-1481995">Jessica Nealon</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>Australian radio host Kyle Sandilands announced on air that he <a href="https://www.abc.net.au/news/2025-02-03/kyle-sandilands-brain-aneurysm-diagnosis/104888826">has a brain aneurysm</a> and needs urgent brain surgery.</p> <p>Typically an aneurysm occurs when a part of the wall of an artery (a type of blood vessel) becomes stretched and bulges out.</p> <p>You can get an aneurysm <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/aneurysm">in any blood vessel</a>, but they are most common in the brain’s arteries and the aorta, the large artery that leaves the heart.</p> <p>Many people can have a brain aneurysm and never know. But a brain (or aortic) aneurysm that ruptures and bursts can be fatal.</p> <p>So, what causes a brain aneurysm? And what’s the risk of rupture?</p> <h2>Weakness in the artery wall</h2> <p>Our arteries need strong walls because blood is constantly pumped through them and pushed against the walls.</p> <p>An <a href="https://www.healthdirect.gov.au/aneurysms">aneurysm</a> can develop if there is a weak part of an artery wall.</p> <p>The walls of arteries are made of three layers: an inner lining of cells, a middle layer of muscle and elastic fibres, and a tough outer layer of mostly collagen (a type of protein). Damage to any of these layers causes the wall to become thin and stretched. It can then balloon outward, leading to an aneurysm.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4399795/">Genetics</a> and <a href="https://www.ninds.nih.gov/health-information/disorders/cerebral-aneurysms">certain inherited disorders</a> can cause weak artery walls and brain aneurysms in some people.</p> <p>For all of us, our artery walls become weaker as we age, and brain aneurysms are more common as we get older. The <a href="https://www.ncbi.nlm.nih.gov/books/NBK557867/">average age for a brain aneurysm</a> to be detected is 50 (Sandilands is 53).</p> <p>Females have a higher risk of brain aneurysm than males <a href="https://www.ncbi.nlm.nih.gov/books/NBK507902/">after about age 50</a>. Declining oestrogen around menopause reduces the collagen in the artery wall, causing it to become weaker.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=400&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/646696/original/file-20250204-15-i55mtq.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=503&amp;fit=crop&amp;dpr=3 2262w" alt="An illustration showing a brain aneurysm." /><figcaption><span class="caption">A brain aneurysm occurs when a part of the wall of an artery balloons out.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/human-brain-blocking-stroke-aneurysm-disease-2171173339">Alfmaler/Shutterstock</a></span></figcaption></figure> <p>High blood pressure can increase the risk of a brain aneurysm.

In atherosclerosis, plaques made mostly of fat build up in arteries and stick to the artery walls.

Cabana drama: 5 expert tips on how not to be branded a twit when using a beach tent

<p><em><a href="https://theconversation.com/profiles/samuel-cornell-1418374">Samuel Cornell</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Debate erupted this week over the growing number of beach tents, or “cabanas”, proliferating on Australian beaches. The controversy, which <a href="https://www.tiktok.com/@gunclediaries/video/7453200613170564370">began on social media</a>, was fuelled by Prime Minister Anthony Albanese who declared it was “not on” for beachgoers to reserve a spot on the sand by erecting a cabana then leaving it vacant for hours.</p> <p>Albanese <a href="https://www.pm.gov.au/media/television-interview-today-show-19">told</a> Nine’s Today show “everyone owns the beach” and staking a claim on the sand was “a breach of that principle, really”.</p> <p>Other critics deem beach cabanas an eyesore. And lifeguards say <a href="https://www.abc.net.au/news/2023-01-21/busy-beaches-noosa-cabana-craze-surf-lifesavers/101875660">the structures can</a> obscure their view of the water, which poses a safety risk.</p> <p>Beach cabanas do, however, serve <a href="https://www.sciencedirect.com/science/article/pii/S0190962208007330?via%3Dihub">a valid purpose</a>. They provide some <a href="https://theconversation.com/i-cant-get-sunburnt-through-glass-shade-or-in-water-right-5-common-sunburn-myths-busted-150640">protection against the sun’s harmful ultraviolet rays</a> and, from a recreational perspective, can enable people to spend longer at the beach on hot days than they might have otherwise.</p> <p>I’m a member of the University of NSW <a href="https://www.beachsafetyresearch.com">Beach Safety Research Group</a>, and I’ve worked with local councils and national parks to address health and safety issues on beaches. So let’s look at how to strike the right balance between personal convenience and public safety when using a cabana.</p> <figure><iframe src="https://www.youtube.com/embed/U4W_2ti5QUk?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>A fair go for all?</h2> <p>In years past, Aussies came to the beach with a towel and maybe a book, stayed a little while then left.</p> <p>But more recently, the use of beach tents and cabanas has grown. It’s likely the result of Australia’s <a href="https://soe.dcceew.gov.au/coasts/pressures/population">growing coastal population</a>, and a rising awareness of the dangers posed by sun exposure.</p> <p>These days, it’s not uncommon to visit a popular beach in summer and find a village of cabanas stretching as far as the eye can see.</p> <p>It’s great to see so many people using the beach. Beaches and oceans are <a href="https://www.sciencedirect.com/science/article/pii/S0013935120310665">health-giving places</a>, though they come with inherent dangers.</p> <p>And of course, in Australia the beach is free for all who wish to use it. It’s an approach in line with our <a href="https://www.theguardian.com/commentisfree/2020/oct/12/even-without-private-clubs-the-egalitarian-australian-beach-is-a-national-myth">supposedly egalitarian culture</a>, in which everyone gets a “fair go”. Here, beaches are a place to be shared, no matter what your income or social status.</p> <p>The approach contrasts to many destinations in Europe, the United States and elsewhere, where large sections of beaches are reserved for private use. At Waikiki beach in Honolulu, for example, people <a href="https://www.waikikibeachservices.com/royal-hawaiian/beach-umbrella-chair-rental/">pay US$100 or more</a> to hire an umbrella and chairs, and a place on the sand for the day.</p> <p>To some naysayers, cabana use in Australia <a href="https://www.theguardian.com/australia-news/2025/jan/07/everyone-owns-the-beach-prime-minister-anthony-albanese-weighs-in-cabana-debate">challenges the notion</a> that the beach is for everyone. They question whether people should be allowed to mark out beach territory no-one else can use. That’s why in 2020, a bid by a private company to introduce paid cabanas on Sydney’s Bondi Beach <a href="https://www.9news.com.au/national/bondi-beach-petition-to-open-paid-cabanas-on-sand-amalfi-beach-club/ef1ddae5-e24e-4dd8-810d-f0d9ba5c2971">prompted a public outcry</a>.</p> <p>Cabanas bring practical challenges, too. They represent an unplanned influx of temporary infrastructure into busy public spaces. Left unchecked, they could cause pedestrian congestion and become a flashpoint for disagreement between beachgoers.</p> <p>The current debate may prompt Australian beach authorities to consider bringing in cabana regulation, similar to what’s in place for <a href="https://www.smh.com.au/national/nsw/does-sydney-need-us-style-cabana-ban-to-curb-beach-spreading-20230202-p5chgi.html">some beaches in the US</a>.</p> <p>In the meantime, here are five tips for safe and fair use of beach cabanas:</p> <p><strong>1. Placement:</strong> Erect your cabana at the back of the beach and away from lifeguard towers or lifesaver tents to avoid obstructing lifeguards’ views. Clear sightlines to the water are essential for ensuring timely emergency responses. This positioning also leaves space closer to the water for other beachgoers, including children playing at the water’s edge.</p> <p><strong>2. Tying down:</strong> Secure your cabana firmly in the sand to prevent it from being blown away by strong winds. Flying cabanas are a danger to other beach users, potentially causing injuries and damage to property.</p> <p><strong>3. Spacing:</strong> Avoid overcrowding by maintaining two to three meters between structures. This ensures free movement and accessibility for all beachgoers, and ensures families and groups can enjoy the beach without feeling cramped. Also, stay within the boundaries of your cabana and don’t claim territory outside its boundaries.</p> <p><strong>4. Emergency access:</strong> Keep pathways and access points clear at all times. This is crucial for lifeguard vehicles, ambulances and surf rescue teams. Unobstructed access can make the difference between life and death in an emergency.</p> <p><strong>5. Common sense:</strong> As with using any shared space, consider the needs of others and apply common sense. How would you feel if someone set up a structure right in front of you, blocking your view of the waves or ruining your vibe? Or if you or a loved one needed medical attention on a beach, would you want an ambulance crew obstructed by an unbroken line of tents?</p> <h2>Looking ahead</h2> <p>In the past, some have called for <a href="https://au.news.yahoo.com/calls-grow-to-ban-cabanas-on-aussie-beaches-get-out-and-leave-051701259.html">a ban on beach cabanas</a>. But the structures appear here to stay – and that’s not a bad thing. Skin cancer <a href="https://www.aihw.gov.au/reports/cancer/cancer-in-adolescents-and-young-adults-in-australi/contents/summary">affects more young Australians</a> than any other cancer, and the Cancer Council <a href="https://www.abc.net.au/news/2023-01-26/cancer-council-beach-cabanas-skin-cancer-rate-highest-in-qld/101887320">applauds the use of cabanas</a>.</p> <p>It’s important to note, however, that cabanas do not <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3873510/">provide complete protection from UV rays</a>. If you’re at the beach all day, <a href="https://theconversation.com/do-beach-cabanas-actually-protect-you-from-the-sun-199102">you might still get too much sun</a> even under a tent.</p> <p>When it comes to your next visit to the coast, by all means pack your cabana. But make sure you use it carefully and responsibly, so everyone’s day at the beach is safe and enjoyable.<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/246882/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/samuel-cornell-1418374"><em>Samuel Cornell</em></a><em>, PhD Candidate, UNSW Beach Safety Research Group + School of Population Health, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mum furious over grandmother’s refusal to use car seat for her child

<p dir="ltr">A mother has voiced her frustration over her own mother’s major babysitting error. </p> <p dir="ltr">The woman, who has a son of her own, shared that her parents regularly look after their grandchild, but has grown more and more annoyed that one request has been ignored. </p> <p dir="ltr">In her lengthy post on Reddit, the woman wrote that her mother has taken her grandson in a car without a car seat more than once. </p> <p dir="ltr">She wrote, "I'm livid and won't be letting her take him out again but needed to vent. My parents look after my son for me now and again, he loves them, and they love him, but my mom is really testing me. Twice now she has had him in someone's car without his car seat."</p> <p dir="ltr">She continued: "The first time it happened, I didn't let her see him for a month. I knew they were taking him out and had left his car seat for them, but she didn't use it as they were only 'going around the corner.' I screamed and shouted about her putting my son at risk.” </p> <p dir="ltr">“She tried to backtrack and lie her way out of it, but at the end of the day, she disrespected me."</p> <p dir="ltr">"That was almost a year ago; yesterday, she had him as I had work in London, and hubby was at work; she said they were taking him out and promised she would use the car seat. I stressed to her how she won't see him again if they don't use it and guess what, they didn't use it."</p> <p dir="ltr">The end of the post reads: "I'm livid, I'm going to see her today to shout and give an ultimatum, why don't people listen?! 'Oh, he was fine. We only went two streets away. You're being dramatic…'"</p> <p dir="ltr">"'Dramatic' when there's an insane storm going on, and anything could have happened. [She] won't be having him again. I feel like a d*** for trusting and believing her.”</p> <p dir="ltr">Hundreds of comments poured in from other mothers backing up the woman’s decision, as one person wrote, "She is playing Russian roulette with your child's life. Stay strong in this decision."</p> <p dir="ltr">Another simply wrote, “Why even take the risk? Why?!"</p> <p dir="ltr"><em>Image credits: Shutterstock</em></p>

Research suggests those who use buy-now-pay-later services end up spending more

<p><em><a href="https://theconversation.com/profiles/ashish-kumar-1056067">Ashish Kumar</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Once, borrowing money to make a purchase was a relatively tedious process, not a spur-of-the-moment thing.</p> <p>True, some stores offered lay-by plans that would let you pay for goods in instalments. But if they didn’t, and you didn’t already have a credit card, you’d have to go to a bank and apply for one.</p> <p>That would mean providing a range of supporting documents, negotiating an appropriate credit limit, and waiting for approval. It’s unlikely you’d apply for credit just for a single, small purchase.</p> <p>In recent years, though, the financial technology or “fintech” revolution in the customer credit market has changed all that, with the meteoric rise of buy-now-pay-later (BNPL) services.</p> <p>BNPL credit allows consumers to split their purchases into smaller, interest-free instalments. It is often directly integrated into online checkouts with fast approval, making it easy to purchase something instantly and spread the cost over coming months.</p> <p>There are some obvious risks. Many BNPL providers charge less visible fees, such as late payment fees and account maintenance fees. In many countries, the BNPL sector is also less regulated than traditional credit.</p> <p>But does it also change our spending habits? Our recent <a href="https://doi.org/10.1016/j.jretai.2024.09.004">research</a> uncovered a concerning insight: consumers who use BNPL services end up spending more money online than those who don’t. This effect is particularly strong among younger shoppers and those with lower incomes.</p> <h2>Our research</h2> <p>We <a href="https://doi.org/10.1016/j.jretai.2024.09.004">analysed</a> data from an online retailer in the Nordic region that offered customers three payment options for online purchases: card, pay on delivery and BNPL.</p> <p>We found that consumers who used BNPL spent an average of 6.42% more than those who didn’t.</p> <p>This increase was particularly noticeable for low-ticket items, suggesting that BNPL may encourage customers to buy more when shopping for smaller, everyday things.</p> <p>Why might this be the case? For one, BPNL spending is constrained by the size of the loans on offer. In the US, the average BNPL loan amount is <a href="https://files.consumerfinance.gov/f/documents/cfpb_consumer-use-of-buy-now-pay-later_2023-03.pdf">US$135</a> (A$217).</p> <p>It may also be related to what’s known in economics as the “<a href="https://www.theguardian.com/business/2008/dec/22/recession-cosmetics-lipstick">lipstick effect</a>”, where customers under financial strain tend to reduce spending on big-ticket items in favour of lower-priced luxuries.</p> <p>Selling such low-ticket items doesn’t always give online retailers the biggest profit margins. But it can play a crucial role in acquiring and retaining customers, and creating opportunities to upsell.</p> <p>Our research also showed that younger, lower-income customers were more likely to spend more when using BNPL services, likely because it provides them with additional “liquidity” – access to cash.</p> <h2>Why might they be spending more?</h2> <p>It’s easy to see why so many consumers like BNPL. Some even think of it as more of a way of payment than a form of credit.</p> <p>The core feature of such services - offering interest-free instalment payments for online purchases - has a significant psychological impact on customers.</p> <p>It leverages the principle that the perceived benefit of spending in the present outweighs the displeasure associated with future payments.</p> <p>This behaviour aligns with theories of “hyperbolic discounting” – our preference for smaller immediate rewards over larger later ones – and the related “<a href="https://www.behavioraleconomics.com/resources/mini-encyclopedia-of-be/present-bias/">present bias</a>” phenomenon.</p> <p>Our results also suggest customers with high category experience – that is, more familiar with the larger product categories carried by a retailer – and those more sensitive to deals and promotions are likely to spend more when online retailers provide BNPL as a payment option.</p> <h2>A growing influence on spending</h2> <p>The economic impact of BNPL is substantial in the countries that have pioneered its adoption.</p> <p>In Australia, birthplace of Afterpay, Zip, Openpay, and Latitude, it’s <a href="https://www.oxfordeconomics.com/wp-content/uploads/2022/10/AFIA_BNPL_Research_Report-1.pdf">estimated</a> that (allowing for flow-on effects) BNPL services contributed A$14.3 billion to gross domestic product (GDP) in the 2021 financial year.</p> <p>Industry research firm Juniper Research <a href="https://www.juniperresearch.com/press/pressreleasesbuy-now-pay-later-users-to-exceed-670-million-globally/">projects</a> the number of BNPL users will exceed 670 million globally by 2028, an increase of more than 100% on current levels.</p> <p>Substantial projected growth in the sector is attributed to multiple factors. These include increasing e-commerce usage, economic pressures, the flexibility of payment options and widespread adoption by merchants.</p> <h2>Buyer, beware</h2> <p>BNPL services can be a convenient way to pay for online purchases. But it’s important to use them responsibly.</p> <p>That means understanding the potential risks and benefits to make your own informed decisions. Be mindful of your spending. Don’t let the allure of easy payments let you get carried away.</p> <p>Customers should explore beyond the marketing tactics of interest-free split payments and pay close attention to terms and conditions, including any fees and penalties. They should treat BNPL like any other form of credit.</p> <p>Whether you’re a shopper considering using BNPL or a business thinking about offering it, our research highlights that it may have the power to significantly influence spending patterns – for better or worse.<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/246686/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/ashish-kumar-1056067"><em>Ashish Kumar</em></a><em>, Senior Lecturer, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do natural fabrics really keep us cooler in summer? Here’s the science

<p><em><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>The Bureau of Meteorology has warned Australia is facing one of the <a href="https://www.abc.net.au/news/2024-10-12/australia-facing-one-of-hottest-summers-on-record-bom/104464014">hottest summers on record</a>. As the weather warms, many of us reach for light-coloured clothes in natural fabrics, such as cotton and linen.</p> <p>But why are natural fabrics like these so much better at keeping us cool when the weather is hot?</p> <p>Here’s what the science says.</p> <h2>Natural fabrics and sweat: a match made in heaven</h2> <p>In hot weather, we sweat. As sweat evaporates, it carries heat away, which helps cool the body down.</p> <p>In hot weather, then, we want clothes that help take moisture away from the body as efficiently as possible.</p> <p>Natural fabrics are made using fibres extracted from plant- or animal-based sources such as cotton, linen, hemp, wool and silk.</p> <p>The primary component of all plant-based fibres is cellulose. Animal-based fibres are made up of proteins such as keratin and silk fibroin.</p> <p>Cellulose molecules are rich in compounds called hydroxyl groups that attract water and moisture. In scientific terms, they are hydrophilic – they love water.</p> <p>So, clothing made of cotton and linen is highly hydrophilic. It tends to absorb moisture and disperse it across the fabric, allowing it to evaporate more easily.</p> <p>This takes the sweat away quickly, making it more comfortable and breathable and allowing us to stay cool in sweltering temperatures.</p> <p>One downside of the natural fabrics is they wrinkle quickly (some people, of course, like that look).</p> <p>And on a really hot, sweaty day, natural fabrics can get heavy and wet.</p> <p>Animal fibres are basically proteins, and their properties vary depending on the source.</p> <p>Wool has been bio-engineered over millions of years to be comfortable to wear. Wool fibres are hydrophilic on the inside and hydrophobic on the outside, meaning they’re both water resistant and good at wicking moisture away.</p> <p>On the other hand, silk fabrics are very good at helping regulate temperature; they keep us cool in hot weather and warm in cold weather.</p> <h2>Synthetic fabrics: less wrinkly, more sweaty</h2> <p>Synthetic fabrics, on the other hand, are lighter and tend to wrinkle less.</p> <p>Common synthetic fabrics (such as polyester, nylon and acrylic) are all made from petroleum-based chemicals.</p> <p>Most synthetic fibres are made of long chains of hydrogen and carbon atoms and do not contain the hydroxyl groups we discussed earlier.</p> <p>Such fibres are therefore hydrophobic – they hate water. This means the water can’t spread evenly across the fabric and evaporate easily.</p> <p>They trap sweat against the skin, making the clothes less breathable and comfortable when the weather is warm and humid.</p> <p>However, some synthetic fabrics used in certain types of active wear can wick sweat away from body.</p> <p>And some semi-synthetic fabrics such as rayon or tencel (which are made from wood pulp or cotton with synthetic fibres) are more breathable than other synthetic fabrics such as polyester or nylon.</p> <h2>Fabric weave makes a difference, too</h2> <p>The colour of the clothing is also a contributing factor to keep you cool during summer. Light colours reflect sunlight away from you and help to keep the body cooler.</p> <p>There is some evidence dark colours absorb the <a href="https://www.sciencedirect.com/science/article/pii/S2214157X23012054">sunlight and associated heat</a>, making the surface of the skin warmer than normal.</p> <p>Another factor affecting breathability and comfort of clothing is the way the fabrics are woven.</p> <p>Fabrics that are loosely woven (sometimes known as “open weave”) with thinner materials naturally have more airflow, which helps you keep cool.</p> <p>For a quick, non-scientific test, hold a fabric up and see how much light passes through it. The more light you can see, the more breathable it likely is.</p> <p>The way the fabric is treated can play a role, too; such as for softening and wrinkle resistance.</p> <p>Using a fabric softener when you do a load of laundry usually doesn’t affect fabric breathability; softeners modify the surface of the fabric but don’t change the internal structure or porous nature of the fabrics.</p> <p>Wrinkle resistance is the ability of the fabric to stay smooth and polished even after washing. Synthetic fabrics are inherently wrinkle resistant. Natural fibres are more prone to wrinkles but can be chemically treated on the fabric surface during manufacturing to make them wrinkle resistant.</p> <p>Such treatments, however, may form layers on top of the fabric blocking the airflow, leading them to be less breathable.<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/240909/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nisa-salim-1442233">Nisa Salim</a>, Senior Lecturer at the School of Engineering, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The chemical <a href="https://www.sciencedirect.com/science/article/pii/S0308814698000764">12-methyltridecanal</a> helps give roast beef its “beefy” flavour, while the sulfur-containing compound <a href="https://www.sciencedirect.com/science/article/pii/S0963996922004422">2-methyl-3-furanthiol</a> is more often found in roast chicken.</p> <p>There are three main types of chemical reactions taking place when roasting meats that produce flavour chemicals.</p> <p>The <a href="https://theconversation.com/kitchen-science-from-sizzling-brisket-to-fresh-baked-bread-the-chemical-reaction-that-makes-our-favourite-foods-taste-so-good-58577">Maillard reaction</a> is responsible for both colour and flavour. This broad reaction type takes place between amino acids from the protein and sugars and simple carbohydrates found in the meat.</p> <p>The Maillard reaction is also the chemistry responsible for many favourite flavours, including roasted coffee, chocolate, steak, toast and more.</p> <h2>A hundred degrees, even more maybe</h2> <p>The other main type of reaction occurring in a hot oven is the breakdown of fats by “<a href="https://doi.org/10.1016/j.foodres.2022.111385">lipid degradation</a>”. This can form hundreds of different chemical compounds. Many of these chemicals are described as “fatty”, “tallowy”, or smell like fried foods.</p> <p>The unique fat profiles found in different animals translate to the profile of flavour chemicals that form from lipid degradation when roasted. Further flavour compounds can arise through the third type of reactions combining products of Maillard reactions and lipid degradation.</p> <p>One specific flavour compound identified as having a “gravy aroma” is known as <a href="https://pubs.acs.org/doi/10.1021/jf9023189">3-mercapto-2-methylpentan-1-ol</a>. This compound comes from roasted vegetables, so including some veggies in your roasting pan will give you more depth of gravy flavour. Also, “cutting onions” is a useful excuse if listening to How to Make Gravy gets you feeling emotional.</p> <h2>The treasure and the trash</h2> <p>Roasting meats causes the fats to “render” and separate from the meat as a liquid. The fat pools in the tray with flavour-rich meat juices.</p> <p>While the fat and the water both carry flavour compounds, too much fat can give the finished gravy an unpleasant mouth feel, or can separate into layers when served.</p> <p>It’s worth pouring off the pan juices into a jug to allow the fat to separate from the liquid so you can control how much fat you’re adding. Be sure to dispose of the excess fat responsibly – <a href="https://theconversation.com/why-shouldnt-i-pour-oil-or-paint-down-the-sink-and-what-should-i-do-instead-206604">don’t pour it down the drain</a>.</p> <h2>Just add flour…</h2> <p>Flour (or, more specifically, starch) is the secret ingredient of a good gravy. Starches are <a href="https://www.sciencedirect.com/science/article/pii/S0168945222000474">large complex chemicals</a> that are made up of lots of sugars joined together.</p> <p>Starch granules are tightly packed and swell greatly when they absorb water. The swollen starch molecules forms a gel-like network that traps water and oil to give a thickened gravy.</p> <p>Wheat flour is most often used as the starch source. Corn and arrowroot starch can also be used. They have a higher percentage of starch than flour and a more neutral flavour.</p> <p>Wheat starch typically requires a larger quantity to be added and longer cooking to form a paste. Whichever starch you use, don’t add it too quickly or without mixing as you’ll form lumps.</p> <h2>…salt, red wine, and a dollop of tomato sauce</h2> <p>Salt is a common ingredient when preparing roast meats, both on the surface of the meat to draw out moisture and as a flavouring agent. The pan juices are typically concentrated as part of the gravy making process.</p> <p>Make sure you taste the gravy before seasoning, as salt will be concentrated by heating.</p> <p>Additional flavour components can be introduced by adding red wine, sherry, stock, or tomato sauce. These ingredients will broaden the flavour profile through sweetness (sugar), acidity (vinegar, citric and malic acids), and umami in the case of tomato sauce (natural glutamates, such as those found in MSG). Some folk even add Vegemite to their gravy for an extra umami boost.</p> <h2>I bet it will taste the same</h2> <p>If you happen to have screwed up your gravy this time, or are after convenience, then you can turn to an instant gravy powder. The main ingredient is typically maltodextrin or another corn-derived (and possibly chemically modified) starch.</p> <p>Shelf-stable powdered fats, salt, colours, and a range of <a href="https://theconversation.com/busting-the-myth-that-all-food-additives-are-bad-a-quick-guide-for-label-readers-82883">flavour additives</a> will be present in varying amounts depending on the style and price point of the product.</p> <p>The advantages of the instant version are speed and uniformity due to the carefully controlled commercial production.</p> <p>So unlike Joe’s concerns for his family’s gravy, an instant gravy will be more likely to taste the same, regardless of who ends up making it.<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/219589/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Track your spending, use cash and DIY gifts: how to keep your costs down this Christmas

<p><em><a href="https://theconversation.com/profiles/angelique-nadia-sweetman-mcinnes-1361909">Angelique Nadia Sweetman McInnes</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>Australians are expected to spend more this Christmas than last, with spending projected to rise to <a href="https://www.shopassociation.org.au/sites/default/files/uploaded-content/field_f_content_file/2024-australian-christmas-shopping-intentions-research-report-cpmaustralia-retailsafari-1.pdf">A$69.7 billion</a>. This is a 2.7% increase on what we spent last year on gifts, food and other treats for ourselves and others.</p> <p>This is a lot at a time when many people are experiencing mortgage stress and high inflation. But by employing smart budgeting and spending strategies we can enjoy a festive Christmas season without huge financial stress.</p> <h2>Know how much you are spending</h2> <p>Being aware of what you are spending is important. So you don’t spend beyond your means, you need to decide what you are going to buy and track what you spend.</p> <p>Using budgeting tools in your banking app will help you monitor your spending. Your bank’s app or a <a href="https://www.savings.com.au/savings-accounts/budgeting-and-saving-apps">variety of budgeting apps</a>, can also help you find deals and stick to your financial goals.</p> <p><a href="https://doi.org/10.1093/jcr/ucac024">Research</a> shows spending decreases when you use an online budgeting app by 15%.</p> <p>Christmas budgeting means setting clear limits, like a gift allowance for each person of, for example, under $10, $25, $50 or $100. This helps us stay on track. Before shopping, we should also ask ourselves: “Is this worth buying?” or “Do I really need this?”.</p> <h2>How to bag a bargain</h2> <p>About <a href="https://www.shopassociation.org.au/sites/default/files/uploaded-content/field_f_content_file/2024-australian-christmas-shopping-intentions-research-report-cpmaustralia-retailsafari-1.pdf">63% of Australian consumers</a> say they start their shopping in November, before the last-minute push to fill the Christmas stockings. This enables them to take advantage of the Black Friday sales on now and Cyber Monday, next Monday.</p> <p>Online research can uncover decent bargains to lower Christmas spending. Or you could wait until the Boxing Day sales to buy discounted gifts for people you don’t see until after December 25.</p> <p>The post-Christmas sales are also good for stocking up on heavily discounted crackers and decorations for next year.</p> <p><a href="https://www.shopassociation.org.au/sites/default/files/uploaded-content/field_f_content_file/2024-australian-christmas-shopping-intentions-research-report-cpmaustralia-retailsafari-1.pdf">Most Australian shoppers</a> (89%) are combining online (websites, mobile apps, social media) with physical in-store shopping. <a href="https://www.shopassociation.org.au/sites/default/files/uploaded-content/field_f_content_file/2024-australian-christmas-shopping-intentions-research-report-cpmaustralia-retailsafari-1.pdf">Major online retailers</a> such as Amazon, eBay, and The Iconic (69%) are now more popular than department stores (59%).</p> <p>There are also thrift and discount stores which offer affordable gifts while using their income to help those in need.</p> <p>By using the internet to compare prices and set price alerts for goods you want to buy, you are more likely to get the best deals. Take time to search for store discounts. Using loyalty programs, coupons, promo codes, and free shipping also helps keep money in your pocket.</p> <h2>Why cash at Christmas is better</h2> <p>The <a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/media-releases/ensuring-future-cash-and-next-steps-phasing-out-cheques#:%7E:text=The%20Government%20will%20mandate%20that,will%20not%20be%20left%20behind.">federal government’s decision</a> last week to require businesses to accept cash, not just credit or debit cards, also has benefits for saving. Cash purchases encourage you to spend wisely, set your <a href="https://resources.depaul.edu/financial-fitness/tackle-overspending/Pages/solutions-for-overspending.aspx">spending limit, and prevent you from overspending, or paying interest and fees on cards</a>.</p> <p>There is also the old “<a href="https://www.ramseysolutions.com/budgeting/envelope-system-explained">cash envelope system</a>” used for centuries and popularised in the 1990s to help curb spending. This sees cash divided into envelopes, each labelled for a specific expense (for example, gifts for A, B, C). Once the money in the envelope is gone, nothing more can be spent.</p> <p>One way to help boost your Christmas budget; while simultaneously decluttering, your home is to sell items you no longer use. There are numerous online sites and bricks and mortar stores where this can be done.</p> <h2>Saving money with DIY</h2> <p>In 2024, Australians will spend an average of <a href="https://www.shopassociation.org.au/sites/default/files/uploaded-content/field_f_content_file/2024-australian-christmas-shopping-intentions-research-report-cpmaustralia-retailsafari-1.pdf">$660 per shopper on gifts</a>, with popular choices including clothing and shoes, books, and gift cards.</p> <p>However, it’s not necessary to buy all your gifts or Christmas decorations. Consider making affordable handmade gifts to add a personal touch. There are demonstration videos online showing you how to re-purpose old items, bake homemade festive treats, create a special moments photo album or scrapbook.</p> <p>Mix Epsom salts, essential oils and dried flowers to create relaxing bath salts or scrubs. Use natural pine cones or salt dough to make ornaments. Make wreaths using pine branches, holly or dried oranges. Sew fabric garlands to place on the tree, fireplace or mantle.</p> <p>Instead of buying multiple extravagant presents for each person, try doing a Secret Santa. This is the low-cost tradition where everyone buys only one gift for one recipient who is chosen using an online tool. Gifts are then given anonymously.</p> <h2>Festive food</h2> <p>Festive food spending is projected to be <a href="https://www.roymorgan.com/findings/9736-ara-roy-morgan-media-release-christmas-spending-2024">$28 billion, up 4.2%</a>, this year, contributing to the overall increase in expected total Christmas spending.</p> <p>To save on food expenses, asks guests to bring a dish to share. Or celebrate Christmas with an economical picnic or BBQ, weather permitting.</p> <p>Get creative with food leftovers to make meals and reduce the amount of food waste, while stretching your wallet further once Christmas has come and gone.</p> <h2>Managing costs, avoiding debt</h2> <p>Sticking to your Christmas budget can feel rewarding. If you do overspend, reflect on why, and adjust your plan. If needed, explore debt options, like credit cards or personal loans, but only as a last resort.</p> <p>Thoughtful planning will help you manage your costs, while enjoying the festive season. After all, the true spirit of Christmas is about creating memories and enjoying time with loved ones, not about overspending.<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/244300/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/angelique-nadia-sweetman-mcinnes-1361909">Angelique Nadia Sweetman McInnes</a>, Academic in Financial Planning, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Italian village offers $1 homes to Americans upset by US election results

<p>An Italian village in Sardinia, Italy is offering one-euro homes to Americans seeking a new start following the results of the 2024 U.S election that saw Donald Trump being re-elected as president. </p> <p>Ollolai has long been trying to persuade outsiders to move in to revive the community after decades of depopulation. </p> <p>Now, it's selling dilapidated houses for as little as one euro — just over a US dollar or $AU1.60 — to entice Americans to move abroad. </p> <p>Following the November 5 outcome, they have launched a website aimed at potential American expats, offering cheap homes in hopes that those disappointed by the result and seeking a fresh start will snap up one of their empty properties. </p> <p>"Are you worned (sic) out by global politics? Looking to embrace a more balanced lifestyle while securing new opportunities?" the website read. </p> <p>"It's time to start building your European escape in the stunning paradise of Sardinia."</p> <p>Mayor Francesco Columbu told CNN that the website was specifically created to attract American voters in the wake of the presidential elections.</p> <p>The mayor loves the United States and is convinced Americans would be the best people to revive the community. </p> <p>"We just really want, and will focus on, Americans above all," he said. </p> <p>"We can't of course ban people from other countries to apply, but Americans will have a fast-track procedure. We are betting on them to help us revive the village, they are our winning card."</p> <p>The village is offering three tiers of accommodation: Free temporary homes to certain digital nomads, ($1.6) homes in need of renovations, and ready-to-occupy houses for prices up to $160,000.</p> <p>The mayor also set up a special team to guide interested buyers through every step of the process including finding contractors, builders and navigating required paperwork. </p> <p>"Of course, we can't specifically mention the name of one US president who just got elected, but we all know that he's the one from whom many Americans want to get away from now and leave the country," Columbo added. </p> <p>"We have specifically created this website now to meet US post-elections relocation needs. The first edition of our digital nomad scheme which launched last year was already solely for Americans."</p> <p>Photos and plans of available empty properties will soon be uploaded to the website. </p> <p>The website has since received nearly 38,000 requests for information on houses, with most of them coming from the United States</p> <p>In the past century, Ollolai's population has shrunk from 2,250 to 1,300 with only a handful of babies born each year. </p> <p>Over the last few years, this has dropped 1,150 residents. </p> <p><em>Image: Shutterstock</em></p> <p> </p>

World reacts as Donald Trump wins US election

<p>World leaders, celebrities and millions of Americans have shared their first reactions and messages of support - or messages of anger, upset and frustration - as Donald Trump claimed his victory in the US election. </p> <p>The Republican leader won both the electoral college vote and the popular vote, taking a hold of the majority of key swing states, as his victory just hours after the polls closed. </p> <p>The win will see Trump re-enter the White House in January as the 47th President, making him the only president to serve two non-consecutive terms in office. </p> <p>Reactions to the unprecedented win flooded online spaces, with world leaders sending their congratulations. </p> <p>Prime Minister Anthony Albanese said the election of the US president marked an important moment for Australia and the Asia Pacific region, and vowed to work closely with the Trump administration.</p> <p>“Australia and America are old allies and we are true friends,” he said. “Our nations are bound by a history of shared sacrifice, a commitment to common values and — above all — enduring respect and affection between our peoples."</p> <p>“I look forward to talking with President Trump and working with him in the best interests of both our nations.”</p> <p>Opposition Leader Peter Dutton also extended his congratulations to the Republican leader on behalf of the federal Coalition, describing the US as an “overwhelming force for good”.</p> <p>Unsurprisingly, Israel’s Prime Minister Benjamin Netanyahu was among the first to speak to Trump, writing on X, “Congratulations on history’s greatest comeback!”</p> <p>“Your historic return to the White House offers a new beginning for America and a powerful recommitment to the great alliance between Israel and America. This is a huge victory! In true friendship.”</p> <p>Elon Musk, petulant billionaire and owner of Twitter, also shared a series of memes on X, after he publicly endorsed Trump throughout his campaign. </p> <p>Among the posts is an image of Musk holding a bathroom sink photoshopped into the Oval Office with the caption "Let that sink in", a reference to how he marked his controversial takeover of X when it was still known as Twitter.</p> <p>Musk also shared a photo of a conversation he was having with Trump as votes were being counted.</p> <p>"The future is gonna be so [fire]," Musk said with American flag emojis.</p> <p>"The future is gonna be fantastic," he said in a follow up post with a photo of his recent SpaceX rocket test that Trump discussed at length, for some reason, in his declaration speech.</p> <p>Despite the messages of well wishes from world leaders, social media has been awash with messages of disbelief and anger since the victory was announced, with many American citizens anxious and scared about the next four years under Trump's controversial <a href="https://www.project2025.org" target="_blank" rel="noopener">Project 2025</a>, which will see mass deportations of immigrants, more tax cuts to the rich, harsher penalties for those seeking abortions or reproductive care, and unprecedented power in the hands of a President with authoritarian aspirations. </p> <p><em>Image credits: Brian Prahl/Shutterstock </em></p>

From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<p><em><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging.</p> <p>Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease.</p> <h2>1. On-the-spot tests</h2> <p>Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis.</p> <p>The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>.</p> <p>The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab.</p> <p><a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light.</p> <p>Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>.</p> <h2>2. Looking at molecules</h2> <p>Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>.</p> <p>A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health.</p> <p>For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present.</p> <p>These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels.</p> <h2>3. Medical imaging</h2> <p>Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging.</p> <p>A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts.</p> <p>Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease.</p> <h2>How about the future?</h2> <p>Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include:</p> <ul> <li> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests</p> </li> <li> <p><a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time</p> </li> <li> <p>AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a></p> </li> <li> <p>a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin</p> </li> <li> <p>fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>.</p> </li> </ul> <p>So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<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/231379/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/matthew-griffith-1539353"><em>Matthew Griffith</em></a><em>, Associate Professor and ARC Future Fellow and Director, UniSA Microscopy and Microanalysis Facilities, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Five reasons why owning a pet is good for us

<p>With more pets than people, Australians have one of the world’s highest pet ownership rates with 62% of us owning at least one pet. And if you’re wondering why we’re so pet mad, research has shown the benefits include companionship, improved mental wellbeing, lower stress and better heart health.</p> <ol> <li><strong>Pets protect us from loneliness</strong></li> </ol> <p>We see our pet as part of the family. Their unconditional (and non-judgemental) love provides us companionship and help to lower stress and anxiety. Interacting with your pet increases feelings of social support and elevates mood. </p> <p>Dog walking increases opportunities for social interaction. When walking outside, fellow dog walkers love to say hello and introduce themselves and their dog to you. Some cafes and restaurants and hotels are dog-friendly venues too. When travelling alone, it’s  wonderful to be able to take your furry companion with you.</p> <ol start="2"> <li><strong>Pets are good for our mental and physical well-being</strong></li> </ol> <p>Pet ownership brings responsibility and the need for skills to know how to best take care of them. These skills will extend to other animals, and other people. Children who have pets develop better social skills when interacting with their friends.</p> <p>Dog owners enjoy lower blood pressure, lower cholesterol levels and less heart disease. While owning a dog is not fully protective, the benefit of all those dog walks are they keep you fitter, healthier and less stressed.</p> <p>If you are unlucky enough to have a heart attack, your long-term survival rate is assisted by having a dog. While interacting with a pet for 10-12 minutes will lower your blood pressure.</p> <p>One of the joys of owning a pet, is the pleasure they provide, and the feeling is mutual. Gazing into the eyes of your beloved pooch, boosts levels of oxytocin our bonding molecule. Our long-standing human-dog relationship was established over 30,000 years ago.</p> <p>Patting or stroking our pets is soothing, especially their silky ears. This is relaxing and how delightful is it when your pet reciprocates with loud purring or offers their tummy for a rub?</p> <ol start="3"> <li><strong>Pets are good for our immune system</strong></li> </ol> <p>You’ve probably heard about your gut microbiome that’s important to keep you healthy. Being a pet owner provides you a healthier microbiome and more robust immune system by promoting more of the beneficial bacteria and lowering the level of harmful, or pathogenic bacteria in our gut.</p> <p>Not only that, stroking your pet raises levels of immunoglobulin A in your body that forms a physical barrier in the gut to protect you against potential invading pathogens.</p> <p>In addition, pregnant mums with a pet in the household are less likely to have infants with childhood allergies, asthma or obesity.</p> <ol start="4"> <li><strong>Pets help us cope better with pain and recovery from illness</strong></li> </ol> <p>Owning a pet has been shown to help manage chronic pain. Pets often sense when their owner isn’t well or in pain and will stay close by, which is very soothing.</p> <p>Watching our pets play and their antics can serve as a useful distraction to our struggles with pain or illness. Having your pet with you (when allowed) in a hospital setting is reassuring and can lift your mood.</p> <p>Animals can help in the work or learning environment. Some workplaces have an office pet policy where you’re allowed to have you pet stay with you while you work. This has been shown to be great for boosting staff morale, collaboration and overall happiness, while keeping work stress lower.</p> <ol start="5"> <li><strong>Pets help us better manage our own self-care</strong></li> </ol> <p>Self-care is always important to stay fit and healthy but isn’t something we always find easy to do. This is where taking responsibility for a pet can help. Teenagers with type one diabetes when given goldfish to care for, did better in monitoring their own blood sugar levels, while having a pet have also been shown to help younger students stay focused and on task, and achieve higher academic results.</p> <p>Pets enrich our lives in so many ways from improved mental well-being to lower stress, elevated mood and greater social support. Whatever type of pet you choose, remember the benefits will work both ways.</p> <p><em><strong>Dr Jenny Brockis is a board-certified lifestyle medicine physician, workplace health and well-being consultant, and author of The Natural Advantage (Major Street Publishing). www.drjennybrockis.com</strong></em></p> <p><em><strong>Image credits: Shutterstock </strong></em></p>

What washing machine settings can I use to make my clothes last longer?

<p><em><a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>Orbiting 400 kilometres above Earth’s surface, the astronauts on the International Space Station live a pretty normal social life, if not for one thing: they happily wear their unwashed clothes <a href="https://www.nasa.gov/centers-and-facilities/glenn/nasa-glenn-interns-take-space-washing-machine-designs-for-a-spin/">for days and weeks at a time</a>. They can’t do their laundry <a href="https://www.esa.int/Enabling_Support/Space_Engineering_Technology/Keeping_your_underwear_clean_on_the_Moon">just yet</a> because water is scarce up there.</p> <p>But down here on Earth, washing clothes is a large part of our lives. <a href="https://bigee.net/media/filer_public/2013/03/28/bigee_domestic_washing_machines_worldwide_potential_20130328.pdf">It’s estimated</a> that a volume of water equivalent to 21,000 Olympic swimming pools is used every day for domestic laundry worldwide.</p> <p>Fibres from our clothes make their way into the environment via the air (during use or in the dryer), water (washing) and soil (lint rubbish in landfill). Most of this fibre loss is invisible – we often only notice our favourite clothing is “disappearing” when it’s too late.</p> <p>How can you ensure your favourite outfit will outlast your wish to wear it? Simple question, complex answer.</p> <h2>Washing machines are not gentle</h2> <p>When you clean the filters in your washing machine and dryer, how often do you stop to think that the lint you’re holding <a href="https://theconversation.com/uk-laundry-releases-microfibres-weighing-the-equivalent-of-1-500-buses-each-year-199712"><em>was</em>, in fact, your clothes</a>?</p> <p>Laundering is harsh on our clothes, and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0250346">research confirms this</a>. Several factors play a role: the type of washing machine, the washing cycle, detergents, temperature, time, and the type of fabric and yarn construction.</p> <p>There are two types of domestic washing machines: top-loader and front-loader. Mechanical agitation (the way the machine moves the clothes around) is one of the things that helps ease dirt off the fabric.</p> <p>Top-loaders have a vertical, bucket-like basket with a paddle, which sloshes clothes around in a large volume of water. Front-loaders have a horizontal bucket which rotates, exposing the clothes to a smaller volume of water – it takes advantage of gravity, not paddles.</p> <p>Top-loading machines <a href="https://link.springer.com/article/10.1007/s12541-010-0047-7">tend to be more aggressive</a> towards fabrics than front-loaders due to the different mechanical action and larger volumes of water.</p> <p>Washing machine panels also present many choices. Shorter, low-temperature programs <a href="https://clevercare.info/more-eco-temperature-tips">are usually sufficient for everyday stains</a>. Choose longer or <a href="https://iprefer30.eu/animations/UK/wash-brochure-uk.pdf">high-temperature programs</a> only for clothing you have concerns about (healthcare uniforms, washable nappies, etc.).</p> <p>Generally, washing machine programs are carefully selected combinations of water volume, agitation intensity and temperature recommended by the manufacturer. They take into consideration the type of fabric and its level of cleanliness.</p> <p>Select the wrong program and you can say goodbye to your favourite top. For example, high temperatures or harsh agitation may cause some fibres to weaken and break, causing holes in the garment.</p> <h2>Some fabrics lose fibres more easily than others</h2> <p>At a microscopic level, the fabric in our clothes is made of yarns – individual fibres twisted together. The nature and length of the fibres, the way they are twisted and the way the yarns form the fabric can determine how many fibres will be lost during a wash.</p> <p>In general, if you want to lose fewer fibres, you should wash less frequently, but some fabrics are affected more than others.</p> <p>Open fabric structures (knits) with loose yarns <a href="https://www.nature.com/articles/s41598-021-98836-6">can lose more fibres</a> than tighter ones. Some sports clothing, like running shirts, are made of continuous filament yarn. These fibres are less likely to come loose in the wash.</p> <p>Cotton fibres are only a few centimetres long. Twisted tightly together into a yarn, they can still escape.</p> <p>Wool fibres are also short, but have an additional feature: scales, which make wool clothes much more delicate. Wool fibres can come loose like cotton ones, but also tangle with each other during the wash due to their scales. This last aspect is what causes wool garments to shrink when <a href="https://journals.sagepub.com/doi/abs/10.1177/004051756403400303">exposed to heat</a> and agitation.</p> <h2>Go easy on the chemicals</h2> <p>The type of detergent and other products you use also makes a difference.</p> <p>Detergents contain a soap component, enzymes to make stains easier to remove at low temperature, and fragrances. Some contain harsher compounds, such as bleaching or whitening agents.</p> <p>Modern detergents are very effective at <a href="https://www.choice.com.au/home-and-living/laundry-and-cleaning/laundry-detergents/review-and-compare/laundry-detergents">removing stains such as food</a>, and you don’t need to use much.</p> <p>An incorrect choice of wash cycles, laundry detergent and bleaching additives could cause disaster. Certain products, like bleach, can <a href="https://site.extension.uga.edu/textiles/textile-basics/understand-your-fibers/">damage some fibres like wool and silk</a>.</p> <p>Meanwhile, research on <a href="https://www.sciencedirect.com/science/article/pii/S0269749120366872?via%3Dihub">fabric softeners and other treatments</a> <a href="https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0233332&amp;type=printable">continues</a> – there’s no one-size-fits-all answer about their potential impact on our clothes.</p> <h2>Just skip laundry day</h2> <p>So, how to ensure your clothes last longer? The main tip is to wash them less often.</p> <p>When it’s time for a wash, carefully read and follow the care labels. In the future, our washing machines will <a href="https://www.teknoscienze.com/tks_article/trends-in-laundry-by-2030/">recognise fabrics and select the wash cycle</a>. For now, that’s our responsibility.</p> <p>And the next time you throw your shirt into the dirty laundry basket, stop. Think of the astronauts orbiting above Earth and ask yourself: if they can go without clean laundry for a few days, maybe I can too? (Although we don’t recommend just burning your dirty undies, either.)<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/224064/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <figure><iframe src="https://www.youtube.com/embed/C1j6KLP492E?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p><em><a href="https://theconversation.com/profiles/alessandra-sutti-1513345">Alessandra Sutti</a>, Associate Professor, Institute for Frontier Materials, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/amol-patil-1513347">Amol Patil</a>, Research Engineer, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/maryam-naebe-1513346">Maryam Naebe</a>, Associate professor, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Humanising AI could lead us to dehumanise ourselves

<p><em><a href="https://theconversation.com/profiles/raffaele-f-ciriello-1079723">Raffaele F Ciriello</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/angelina-ying-chen-2230113">Angelina Ying Chen</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Irish writer John Connolly <a href="https://www.goodreads.com/quotes/3147986-the-nature-of-humanity-its-essence-is-to-feel-another-s">once said</a>: "The nature of humanity, its essence, is to feel another’s pain as one’s own, and to act to take that pain away."</p> <p>For most of our history, we believed empathy was a uniquely human trait – a special ability that set us apart from machines and other animals. But this belief is now being challenged.</p> <p>As AI becomes a bigger part of our lives, entering even our most intimate spheres, we’re faced with a philosophical conundrum: could attributing human qualities to AI diminish our own human essence? Our <a href="https://www.researchgate.net/publication/375086411_Feels_Like_Empathy_How_Emotional_AI_Challenges_Human_Essence">research</a> suggests it can.</p> <h2>Digitising companionship</h2> <p>In recent years, AI “companion” apps such as Replika have attracted millions of users. Replika allows users to create custom digital partners to engage in intimate conversations. Members who pay for <a href="https://help.replika.com/hc/en-us/articles/360032500052-What-is-Replika-Pro#:%7E:text=Replika%20Pro%20gives%20you%20access,relationship%20status%20to%20Romantic%20Partner.">Replika Pro</a> can even turn their AI into a “romantic partner”.</p> <p>Physical AI companions aren’t far behind. Companies such as JoyLoveDolls are selling <a href="https://www.joylovedolls.com/collections/sex-robots">interactive sex robots</a> with customisable features including breast size, ethnicity, movement and AI responses such as moaning and flirting.</p> <p>While this is currently a niche market, history suggests today’s digital trends will become tomorrow’s global norms. With about <a href="https://www.statista.com/chart/31243/respondents-who-feel-fairly-or-very-lonely/">one in four</a> adults experiencing loneliness, the demand for AI companions will grow.</p> <h2>The dangers of humanising AI</h2> <p>Humans have long attributed human traits to non-human entities – a tendency known as anthropomorphism. It’s no surprise we’re doing this with AI tools such as ChatGPT, which appear to “think” and “feel”. But why is humanising AI a problem?</p> <p>For one thing, it allows AI companies to exploit our tendency to form attachments with human-like entities. Replika is <a href="https://replika.com">marketed</a> as “the AI companion who cares”. However, to avoid legal issues, the company elsewhere points out Replika isn’t sentient and merely learns through millions of user interactions.</p> <p>Some AI companies overtly <a href="https://www.space.gov.au/news-and-media/akin-assistive-ai-improve-life-space-and-earth">claim</a> their AI assistants have empathy and can even anticipate human needs. Such claims are misleading and can take advantage of people seeking companionship. Users may become <a href="https://theconversation.com/i-tried-the-replika-ai-companion-and-can-see-why-users-are-falling-hard-the-app-raises-serious-ethical-questions-200257">deeply emotionally invested</a> if they believe their AI companion truly understands them.</p> <p>This raises serious ethical concerns. A user <a href="https://www.researchgate.net/publication/374505266_Ethical_Tensions_in_Human-AI_Companionship_A_Dialectical_Inquiry_into_Replika">will hesitate</a> to delete (that is, to “abandon” or “kill”) their AI companion once they’ve ascribed some kind of sentience to it.</p> <p>But what happens when said companion unexpectedly disappears, such as if the user can no longer afford it, or if the company that runs it shuts down? While the companion may not be real, the feelings attached to it are.</p> <h2>Empathy – more than a programmable output</h2> <p>By reducing empathy to a programmable output, do we risk diminishing its true essence? To answer this, let’s first think about what empathy really is.</p> <p>Empathy involves responding to other people with understanding and concern. It’s when you share your friend’s sorrow as they tell you about their heartache, or when you feel joy radiating from someone you care about. It’s a profound experience – rich and beyond simple forms of measurement.</p> <p>A fundamental difference between humans and AI is that humans genuinely feel emotions, while AI can only simulate them. This touches on the <a href="https://www.researchgate.net/publication/375086411_Feels_Like_Empathy_How_Emotional_AI_Challenges_Human_Essence">hard problem of consciousness</a>, which questions how subjective human experiences arise from physical processes in the brain.</p> <p>While AI can simulate understanding, any “empathy” it purports to have is a result of programming that mimics empathetic language patterns. Unfortunately, AI providers have a financial incentive to trick users into growing attached to their seemingly empathetic products.</p> <h2>The dehumanAIsation hypothesis</h2> <p>Our “dehumanAIsation hypothesis” highlights the ethical concerns that come with trying to reduce humans to some basic functions that can be replicated by a machine. The more we humanise AI, the more we risk dehumanising ourselves.</p> <p>For instance, depending on AI for emotional labour could make us less tolerant of the imperfections of real relationships. This could weaken our social bonds and even lead to emotional deskilling. Future generations may become less empathetic – losing their grasp on essential human qualities as emotional skills continue to be commodified and automated.</p> <p>Also, as AI companions become more common, people may use them to replace real human relationships. This would likely increase loneliness and alienation – the very issues these systems claim to help with.</p> <p>AI companies’ collection and analysis of emotional data also poses significant risks, as these data could be used to manipulate users and maximise profit. This would further erode our privacy and autonomy, taking <a href="https://theconversation.com/explainer-what-is-surveillance-capitalism-and-how-does-it-shape-our-economy-119158">surveillance capitalism</a> to the next level.</p> <h2>Holding providers accountable</h2> <p>Regulators need to do more to hold AI providers accountable. AI companies should be honest about what their AI can and can’t do, especially when they risk exploiting users’ emotional vulnerabilities.</p> <p>Exaggerated claims of “genuine empathy” should be made illegal. Companies making such claims should be fined – and repeat offenders shut down.</p> <p>Data privacy policies should also be clear, fair and without hidden terms that allow companies to exploit user-generated content.</p> <p>We must preserve the unique qualities that define the human experience. While AI can enhance certain aspects of life, it can’t – and shouldn’t – replace genuine human connection.<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/240803/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/raffaele-f-ciriello-1079723">Raffaele F Ciriello</a>, Senior Lecturer in Business Information Systems, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/angelina-ying-chen-2230113">Angelina Ying Chen</a>, PhD student , <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eight simple changes to our neighbourhoods can help us age well

<p><em><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p>Where we live can play a big part in ageing well, largely because of the links between physical activity and wellbeing. <a href="https://www.ahuri.edu.au/__data/assets/pdf_file/0012/2181/AHURI_Final_Report_No214_Downsizing-amongst-older-Australians.pdf">Research shows</a> that two-thirds of Australians prefer to age in place. That is, we want to live independently in our homes for as long as we can. Our neighbourhoods and their design can then improve or hinder our ability to get out of the house and be physically active.</p> <p>The rapid ageing of Australia’s population only adds to the importance of neighbourhood design. In 2016, 15% of Australians were aged 65 or older. That proportion is <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/overview">projected to double</a> by 2056.</p> <p>These trends present several <a href="https://www.aihw.gov.au/reports-statistics/population-groups/older-people/reports">social and economic challenges</a>, particularly for the health sector. Designing neighbourhoods in ways that promote physical activity can help overcome these challenges.</p> <h2>Eight simple steps</h2> <p>The following is a short list of <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0471-5">evidence-based steps</a> local and state governments can take to assist older people to be physically active. These involve minor but effective changes to neighbourhood design.</p> <p><strong>Improve footpaths:</strong> Research indicates that older people have a <a href="https://theconversation.com/why-older-people-get-osteoporosis-and-have-falls-68145">higher risk of falls</a>. Ensuring footpaths are level and crack-free, and free from obstructions, will encourage walking among older people – especially those with a disability.</p> <p><strong>Connected pedestrian networks:</strong> Introducing footpaths at the end of no-through-roads and across long street blocks reduces walking distances to destinations. This makes walking a more viable option.</p> <p><strong>Slowing traffic in high-pedestrian areas:</strong> Slowing traffic <a href="https://www.heartfoundation.org.au/images/uploads/publications/Safe-Speed-Evidence-Report.pdf">improves safety</a> by reducing the risk of a collision. It also reduces the risk of <a href="https://www.ncbi.nlm.nih.gov/pubmed/28557669">death and serious injury</a> in the event of a collision.</p> <p><strong>Age-friendly street crossings:</strong> Installing longer pedestrian crossing light sequences gives older pedestrians <a href="https://academic.oup.com/ageing/article/41/5/690/47318/Most-older-pedestrians-are-unable-to-cross-the">more time to cross</a>, and installing refuge islands means those who walk more slowly can cross the street in two stages.</p> <p><strong>Disabled access at public transport:</strong> Although a form of motorised transport, public transport users undertake more incidental physical activity compared with car users. This is because they walk between transit stops and their origins and destinations. Improving disabled access helps make public transport a viable option for more older people.</p> <p><strong>Places to rest:</strong> <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/1471-2458-13-1054">Providing rest spots</a> such as benches enables older people to break up their walk and rest when needed.</p> <p><strong>Planting trees:</strong> Planting trees <a href="http://www.sciencedirect.com/science/article/pii/S0277953614004109?via%3Dihub">creates more pleasant scenery</a> to enjoy on a walk. It also provides shade on hot days.</p> <p><strong>Improving safety:</strong> Ensuring that streets are well-lit and reducing graffiti and signs of decay are likely to <a href="https://www.ncbi.nlm.nih.gov/pubmed/24552845">improve perceptions of safety</a> among older people.</p> <h2>Why physical activity matters</h2> <p>Physical function – the ability to undertake everyday activities such as walking, bathing and climbing stairs – often declines as people age. The reason for this is that ageing is often accompanied by a reduction in muscle strength, flexibility and cardiorespiratory reserves.</p> <p>Regular physical activity can <a href="https://www.ncbi.nlm.nih.gov/pubmed/14552936">prevent or slow the decline</a> in physical function, even among those with existing health conditions.</p> <p>Middle-to-older aged adults can reduce their risk of physical function decline <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/1479-5868-7-38">by 30%</a> with regular physical activity (at least 150 minutes per week). This includes recreational physical activity, like walking the dog, or incidental physical activity, such as walking to the shops or to visit friends.</p> <p>By making minor changes as outlined above, the health and longevity of our elderly population can be extended. Such changes will help our elderly age well in place.</p> <p><em><a href="https://theconversation.com/profiles/jerome-n-rachele-251972">Jerome N Rachele</a>, Research Fellow in Social Epidemiology, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a>; <a href="https://theconversation.com/profiles/james-f-sallis-407885">James F Sallis</a>, Professorial Fellow, Institute for Health and Ageing, Australian Catholic University, and Emeritus Professor, Department of Family Medicine and Public Health, <a href="https://theconversation.com/institutions/university-of-california-san-diego-1314">University of California, San Diego</a>, and <a href="https://theconversation.com/profiles/venurs-loh-118864">Venurs Loh</a>, PhD Candidate, Institute for Health and Ageing, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

<p><em><a href="https://theconversation.com/profiles/inge-gnatt-1425767">Inge Gnatt</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Have you ever noticed changes in your eating habits when you are sad, bored or anxious?</p> <p>Many people report eating either more, or less, as a way of helping them to cope when they experience difficult emotions.</p> <p>Although this is a very normal response, it can take the pleasure out of eating, and can become distressing and bring about other feelings of <a href="https://doi.org/10.1016/j.eatbeh.2018.02.008">shame and self-criticism</a>.</p> <p>Adding to the complexity of it all, we live in a world where <a href="https://butterfly.org.au/diet-culture-101/">diet culture</a> is unavoidable, and our relationship to eating, food and body image can become complicated and confusing.</p> <h2>Emotional eating is common</h2> <p>“Emotional eating” refers to the eating behaviours (typically eating more) that occur in response to difficult emotions.</p> <p><a href="https://doi.org/10.3390/ijerph18041744">Research shows</a> around 20% of people regularly engage in emotional eating, with a higher prevalence <a href="https://doi.org/10.1371/journal.pone.0285446">among adolescents</a> and women. In a <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0285446#sec012">study</a> of more than 1,500 adolescents, 34% engaged in emotional eating while sad and 40% did so while anxious.</p> <p>Foods consumed are often fast-foods and other energy-dense, nutrient-poor convenience foods.</p> <h2>Stress, strong emotions and depression</h2> <p>For some people, emotional eating was simply a <a href="https://doi.org/10.1038/s41598-017-09519-0">habit formed earlier in life</a> that has persisted over time.</p> <p>But other factors might also contribute to the likelihood of emotional eating. The physiological effects of stress and strong emotions, for example, can influence hormones such as <a href="https://doi.org/10.1016/S0306-4530(00)00035-4">cortisol, insulin and glucose</a>, which can also increase appetite.</p> <p>Increased impulsivity (<a href="https://doi.org/10.1176/appi.ajp.158.11.1783">behaving</a> before thinking things through), vulnerability to depression, a tendency to ruminate and <a href="https://doi.org/10.1080/1047840X.2014.940781">difficulties regulating emotions</a> also <a href="https://doi.org/10.1097/FBP.0b013e328357bd4e">increase the likelihood</a> of emotional eating.</p> <h2>So what do you do?</h2> <p>First, know that fluctuations in eating are normal. However, if you find that the way you eat in response to difficult emotions is not working for you, there are a few things you can do.</p> <p>Starting with small things that are achievable but can have a huge impact, such as prioritising <a href="https://theconversation.com/no-sleep-challenge-the-dangers-of-sleep-deprivation-236608">getting enough sleep</a> and <a href="https://insideoutinstitute.org.au/podcasts/episode-3-the-mindful-dietitian-fiona-sutherland">eating regularly</a>.</p> <p>Then, you can start to think about how you handle your emotions and hunger cues.</p> <h2>Expand your emotional awareness</h2> <p>Often we label emotions as good or bad, and this can result in fear, avoidance, and <a href="https://youtu.be/NDQ1Mi5I4rg?si=lv9d8qjUThSsemXG">unhelpful coping strategies</a> such as emotional eating.</p> <p>But it’s also important to <a href="https://www.pspnet.ca/assets/the-gottman-institute-the-feeling-wheel-v2.pdf">differentiate</a> the exact emotion. This might be feeling isolated, powerless or victimised, rather than something as broad as sad.</p> <p>By <a href="https://headspace.org.au/online-and-phone-support/interactive-tools/activities/understanding-emotions/">noticing</a> what the emotion is, we can bring curiosity to what it means, how we feel in our minds and bodies, and how we think and behave in response.</p> <h2>Tap into your feelings of hunger and fullness</h2> <p>Developing an intuitive way of eating is another helpful strategy to promote <a href="https://insideoutinstitute.org.au/blog/what-is-normal-eating">healthy eating behaviours</a>.</p> <p>Intuitive eating means recognising, understanding and responding to internal signals of hunger and fullness. This might mean tuning in to and acknowledging physical hunger cues, responding by eating food that is nourishing and enjoyable, and identifying sensations of fullness.</p> <p>Intuitive eating <a href="https://doi.org/10.1002/eat.23509">encourages flexibility</a> and thinking about the pleasure we get from food and eating. This style of eating also allows us to enjoy eating out with friends, and sample local delicacies when travelling.</p> <p>It can also reduce the psychological distress from feeling out of control with your <a href="https://doi.org/10.1016/j.jand.2013.12.024">eating</a> habits and the associated negative <a href="https://doi.org/10.1016/j.appet.2015.10.012">body image</a>.</p> <h2>When is it time to seek help?</h2> <p>For some people, the thoughts and behaviours relating to food, eating and body image can negatively impact their life.</p> <p>Having the support of friends and family, accessing <a href="https://nedc.com.au/eating-disorder-resources/interactive-digital-resource-for-eating-disorders">online resources</a> and, in some instances, seeing a trained professional, can be very helpful.</p> <p>There are many <a href="https://doi.org/10.1007/s00787-020-01498-4">therapeutic interventions</a> that work to <a href="https://doi.org/10.1016/j.copsyc.2015.02.010">improve aspects</a> associated with emotional eating. These will depend on your situation, needs, stage of life and other factors, such as whether you are <a href="https://nedc.com.au/eating-disorders/types/neurodivergence">neurodivergent</a>.</p> <p>The best approach is to engage with someone who can bring compassion and understanding to your personal situation, and work with you collaboratively. This work might include:</p> <ul> <li>unpacking some of the patterns that could be underlying these emotions, thoughts and behaviours</li> <li>helping you to discover your emotions</li> <li>supporting you to process other experiences, such as trauma exposure</li> <li>developing a more flexible and intuitive way of eating.</li> </ul> <p>One of the dangers that can occur in response to emotional eating is the temptation to diet, which can lead to disordered eating, and eating disorder behaviours. Indicators of a potential <a href="https://nedc.com.au/eating-disorders/eating-disorders-explained/whats-an-eating-disorder">eating disorder</a> can include:</p> <ul> <li>recent rapid weight loss</li> <li>preoccupation with weight and shape (which is usually in contrast to other people’s perceptions)</li> <li>eating large amounts of food within a short space of time (two hours or less) and feeling a sense of loss of control</li> <li>eating in secret</li> <li>compensating for food eaten (with vomiting, exercise or laxatives).</li> </ul> <p><a href="https://nedc.com.au/eating-disorders/treatment-and-recovery/treatment-options">Evidence-based approaches</a> can support people experiencing eating disorders.

30 years of Friends: how the US sitcom became an enduring global sensation

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/richard-howells-1225412">Richard Howells</a>, <a href="https://theconversation.com/institutions/kings-college-london-1196">King's College London</a></em></p> <p>I have to be honest – I didn’t actually watch the first episode of the classic TV series Friends when it originally aired in the US on September 22 1994. Nor did I bother when it first turned up on British television the following spring.</p> <p>But the final instalment was a different matter. I was on a road trip in the US at the time and checked into a motel on the outskirts of Cincinnati, Ohio specially to catch the concluding episode (The Last One) on May 6 2004. Room service arrived in the nick of time. My burger and beer only fuelled my appetite for what was to come – and the anticipation of guessing what the final line would be.</p> <p>So why the big change? How did my attitude evolve from indifference in the nineties to excitedly pulling off the interstate in the noughties? The answer is key to the show’s success – and why it remains so popular today.</p> <p>Back in 1994, the initial premise of Friends seemed to lack promise. The plot revolved round six not especially interesting characters, and none of the cast was especially famous (at least to me). The show was set mainly in two adjacent apartments in Manhattan and a coffee bar called Central Perk to which the characters returned almost every episode and in which (in the best sitcom tradition) the best seats were always available. Crucially, not a lot actually happened.</p> <h2>The power of the ensemble</h2> <p>So why did it work? The first important thing is that Friends was not so much a situation comedy as a character comedy. That meant it did not need a remarkable premise or dramatic incidents to drive the show. It was an ensemble piece in which we gradually got to know the characters and the friends became our friends.</p> <p>The show was built around everyday storylines – crushes, romances and misunderstandings or maybe something as gently amusing as Ross overdoing the teeth whitener. Viewers began to identify with individual characters (<a href="https://www.buzzfeed.com/ljune/are-you-more-rachel-or-monica-from-friends-alfsqwp6hf">“are you a Monica or a Rachel?”</a>) or to take sides on the issues of the day. What, for example, are the relationship rules of being “on a break”?</p> <figure><iframe src="https://www.youtube.com/embed/TIK01MpwWGg?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">One episode of Friends revolves around Ross (David Schwimmer) getting his teeth whitened.</span></figcaption></figure> <p>Friends was, of course, very well produced, cast and written. As it became even more successful, it survived the normally perilous inclusion of <a href="https://www.youtube.com/watch?v=xHLaISBRmdI">celebrity guest stars</a> and – vitally – it never “jumped the shark” (industry-speak for growing out of its initial premise or building up to dramatic, but ultimately silly, plot gimmicks from which it is impossible to recover). Ultimately, and hearteningly, the six characters all remained friends.</p> <p>Beneath the professional craft and production polish of Friends, it is the concept of friendship, underscored with by the viewer’s sense of aspiration, which ultimately explains the series’ success then and now.</p> <p>One of the functions of popular culture is to provide a better imaginary world than the one we actually inhabit. In some ways this is simply compensation for the reality of the everyday: we dream of that which we do not have. It’s what the great Utopian sociologist Ernst Bloch called <a href="https://www.marxists.org/archive/bloch/hope/introduction.htm">“wishful images in the mirror”</a> – except that the mirror here is a television screen.</p> <p>The world of Monica, Rachel, Joey, Chandler, Phoebe and Ross is certainly a wishful one for many. They live in improbably nice apartments for their jobs (or lack of them), and they are defined by their personalities rather than their careers. They are good looking and well dressed, and the series centres on their ample leisure and social time. Unlike reality, arguments are always overcome and – most importantly of all – friendship always triumphs.</p> <figure><iframe src="https://www.youtube.com/embed/pPM7VxnVViw?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The first and last scene of Friends.</span></figcaption></figure> <p>What a contrast this vision provides to the actual lives of so many people today. The real world is beset with isolation, loneliness, sometimes insurmountable problems, occasionally fear and certainly drudgery. But with Friends, as the <a href="https://www.youtube.com/watch?v=sLisEEwYZvw">chirpy theme song</a> reminds us, there is always someone “there for you” – if only in surrogate.</p> <p>Some critics today carp about the show’s <a href="https://metro.co.uk/2023/04/02/lack-of-diversity-on-friends-mocked-on-snl-after-years-of-criticism-18542168/">lack of diversity</a> and <a href="https://www.cosmopolitan.com/uk/entertainment/a38817/11-times-friends-sexist-homophobic/">outdated attitudes</a> to the cultural issues of the present day. While this may be true, like TV series, criticism also dates. And series which have long gone into reruns, repeats, streaming and syndication are virtually critic-proof in that they are recommended by word of mouth rather than increasingly ideologically centred reviews. Viewers just want it to be funny.</p> <p>Oh: And in case you were wondering, the final line in the whole of Friends went to the <a href="https://theconversation.com/matthew-perry-the-power-of-celebrities-speaking-publicly-about-their-addiction-216879">late Matthew Perry</a> as Chandler Bing. When Rachel suggests they all go for one last coffee, Chandler quips: “Sure.

The internet is worse than it used to be. How did we get here, and can we go back?

<p><em><a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722"><em>The University of Melbourne</em></a></em></p> <p>When it comes to our experience of the internet, “the times, <a href="https://en.wikipedia.org/wiki/The_Times_They_Are_a-Changin%27_(song)">they are a-changin’</a>”, as Bob Dylan would say. You can’t quite recall how, but the internet certainly feels different these days.</p> <p>To some, it is “<a href="https://www.npr.org/2024/01/16/1224878097/everyday-users-are-complaining-that-the-internet-is-more-chaotic-than-ever">less fun and less informative</a>” than it used to be. To others, online searches are made up of “<a href="https://www.theverge.com/c/23998379/google-search-seo-algorithm-webpage-optimization?src=longreads">cookie cutter</a>” pages that drown out useful information and are saturated with scams, spam and content generated by artificial intelligence (AI).</p> <p>Your social media feeds are full of eye-catching, provocative, hyper-targeted, or anger-inducing content, from <a href="https://theconversation.com/the-dead-internet-theory-makes-eerie-claims-about-an-ai-run-web-the-truth-is-more-sinister-229609">bizarre AI-generated imagery</a> to robot-like comments. You’re lucky if your video feeds are not solely made up of exhortations to “subscribe”.</p> <p>How did we get here? And can we claw our way back?</p> <h2>Commercial interests rule</h2> <p>One major factor contributing to the current state of the internet is its over-commercialisation: financial motives drive much of the content. This has arguably led to the prevalence of sensationalism, prioritising virality over information quality.</p> <p>Covert and deceptive advertising is widespread, blurring the line between commercial and non-commercial content to attract more attention and engagement.</p> <p>Another driving force is the dominance of tech giants like Google, Meta and Amazon. They reach billions worldwide and wield immense power over the content we consume.</p> <p>Their platforms use advanced tracking technologies and opaque algorithms to generate hyper-targeted media content, powered by extensive user data. This creates <a href="https://www.campaignasia.com/article/the-echo-chamber-effect-how-algorithms-shape-our-worldview/491762">filter bubbles</a>, where users are exposed to limited content that reinforces their existing beliefs and biases, and <a href="https://philarchive.org/archive/NGUECA">echo chambers</a> where other viewpoints are actively discredited.</p> <p>Bad actors like <a href="https://abcnews.go.com/Technology/ai-fuel-financial-scams-online-industry-experts/story?id=103732051">cyber criminals and scammers</a> have been an enduring problem online. However, evolving technology like generative AI has further empowered them, enabling them to create highly realistic fake images, deepfake videos and <a href="https://www.newyorker.com/science/annals-of-artificial-intelligence/the-terrifying-ai-scam-that-uses-your-loved-ones-voice">voice cloning</a>.</p> <p>AI’s ability to automate content creation has also flooded the internet with low-quality, misleading and harmful material at an unprecedented scale.</p> <p>In sum, the accelerated commercialisation of the internet, the dominance of media tech giants and the presence of bad actors have infiltrated content on the internet. The rise of AI further intensifies this, making the internet more chaotic than ever.</p> <h2>Some of the ‘good’ internet remains</h2> <p>So, what was the “good internet” some of us long for with nostalgia?</p> <p>At the outset, the internet was meant to be a free egalitarian space people were meant to “surf” and “browse”. Knowledge was meant to be shared: sites such as Wikipedia and The Internet Archive are continuing bastions of knowledge.</p> <p>Before the advent of filter bubbles, the internet was a creative playground where people explored different ideas, discussed varying perspectives, and collaborated with individuals from “outgroups” – those outside their social circles who may hold opposing views.</p> <p>Early social media platforms were built on the ethos of reconnecting with long-lost classmates and family members. Many of us have community groups, acquaintances and family we reach out to via the internet. The “connection” aspect of the internet remains as important as ever – as we all saw during the COVID pandemic.</p> <p>What else do we want to preserve? Privacy. A New Yorker cartoon joke in 1993 stated that “<a href="https://web.archive.org/web/20051029045942/http://www.unc.edu/depts/jomc/academics/dri/idog.html">on the internet, nobody knows you’re a dog</a>”. Now everyone – especially advertisers – wants to know who you are. To quote the <a href="https://www.oaic.gov.au/privacy/your-privacy-rights/your-personal-information/what-is-privacy">Office of the Australian Information Commissioner</a>, one of the tenets of privacy is “to be able to control who can see or use information about you”.</p> <p>At the very least, we want to control what big tech knows about us, especially if they could stand to profit from it.</p> <h2>Can we ever go back?</h2> <p>We can’t control “a changin’” times, but we can keep as much of the good parts as we can.</p> <p>For starters, we can vote with our feet. Users can enact change and bring awareness to problems on existing platforms. In recent times, we have seen this with the <a href="https://theconversation.com/thinking-of-breaking-up-with-twitter-heres-the-right-way-to-do-it-195002">exodus of users</a> from X (formerly Twitter) to other platforms, and the <a href="https://www.economist.com/the-economist-explains/2023/06/26/why-reddit-users-are-protesting-against-the-sites-leadership">platform-wide protest against Reddit</a> for changing its third-party data access policies.</p> <p>However, voting with our feet is only possible when there’s competition. In the case of X, various other platforms – from Mastodon to Threads to Bluesky – enable users to pick one that aligns with their preferences, values and social circles. Search engines have alternatives, too, such as DuckDuckGo or Ecosia.</p> <p>But competition can only be created by moving to decentralised systems and removing monopolies. This actually happened in the early days of the internet during the 1990s “<a href="https://thehistoryoftheweb.com/browser-wars/">browser wars</a>”, when Microsoft was eventually accused of illegally monopolising the web browser market in <a href="https://en.wikipedia.org/wiki/United_States_v._Microsoft_Corp.">a landmark court case</a>.</p> <p>As users of technology, all of us must remain vigilant about threats to our privacy and knowledge. With cheap and ubiquitous generative AI, misleading content and scams are more realistic as ever.</p> <p>We must exercise healthy scepticism and ensure those most at risk from online threats – such as children and older people – are educated about potential harms.</p> <p>Remember, the internet is not optimised for your best interests. It’s up to you to decide how much power you give to the tech giants who are fuelling theirs.<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/236513/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, Senior Lecturer of Information Systems, School of Computing and Information Systems; and (Honorary) Senior Fellow, Melbourne Law School, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, Associate Professor in Media and Communications, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
