What to claim for lost, delayed or damaged bags on overseas flights

<p><em><a href="https://theconversation.com/profiles/rebecca-johnston-123333">Rebecca Johnston</a>, <a href="https://theconversation.com/institutions/university-of-notre-dame-australia-852">University of Notre Dame Australia</a> and <a href="https://theconversation.com/profiles/david-hodgkinson-6574">David Hodgkinson</a>, <a href="https://theconversation.com/institutions/the-university-of-western-australia-1067">The University of Western Australia</a></em></p> <p>If you get on a plane and your baggage ends up being delayed, damaged or lost, who’s responsible: you or the airline? And what rules apply when you’re flying between different countries – even if you don’t have travel insurance?</p> <p>Airlines (otherwise known as carriers) generally include baggage requirements in their terms and conditions of carriage, which are set out or referred to on your ticket. These are the rules that apply to the journey that you have booked.</p> <p>But for international flights, a carrier’s liability for damage, loss or delay of baggage is governed by a number of overarching international treaties, which many passengers aren’t aware of.</p> <h2>International agreements</h2> <p>The <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.1929/doc.html">Warsaw Convention</a> of 1929 was the first of these treaties, and the latest is the passenger-friendly 1999 <a href="http://www.jus.uio.no/lm/air.carriage.unification.convention.montreal.1999/">Montreal Convention</a>.</p> <p>In order for one of these treaties to apply to a particular journey, the same treaty must be in place at the point of departure and the passenger’s final destination.</p> <p>For many trips, the agreement that will apply will be the Montreal Convention, which has to date <a href="http://www.icao.int/secretariat/legal/List%20of%20Parties/Mtl99_EN.pdf">108 state parties</a>, covering everywhere from Albania and Australia to Zambia. In time, the Montreal Convention is expected to apply to almost all air travel.</p> <p>The Warsaw Convention (as amended by the <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.hague.protocol.1955/doc.html">Hague Protocol</a> and <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.montreal.protocol.4.1975/doc.html">Montreal Protocol No. 4</a>) will generally apply where the Montreal Convention does not. It is less favourable to passengers.</p> <p>All these treaties have similar provisions to deal with baggage claims – but very different limits to what you might get if you need to make a claim.</p> <h2>What the airline is responsible for</h2> <p>A carrier is liable if your checked baggage is lost, delayed or damaged regardless of fault.</p> <p>This is so unless the damage resulted from the inherent defect or quality of the baggage or, in terms of delay, if it proves that it took all reasonable measures to avoid the damage occasioned by that delay.</p> <p>As for unchecked baggage (that is, carry-on baggage), the carrier is only liable if the damage is due to the fault of the carrier or its agents.</p> <p>Unless otherwise specified, reference to “baggage” includes both checked and unchecked baggage.</p> <h2>Calculating baggage compensation</h2> <p>Under the Warsaw Convention (as amended by the <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.hague.protocol.1955/doc.html">Hague Protocol</a> and <a href="http://www.jus.uio.no/lm/air.carriage.warsaw.convention.montreal.protocol.4.1975/doc.html">Montreal Protocol No. 4</a>) and the Montreal Convention, liability limits are expressed in <a href="http://www.imf.org/external/np/exr/facts/sdr.HTM">special drawing rights</a> (SDRs).</p> <p>An SDR is a type of foreign exchange reserve asset created by the International Monetary Fund. Its value is based on an artificial basket of currencies consisting of the US dollar, the euro, the pound and the Japanese yen. The liability limits are reviewed every five years.</p> <p>As of October 16, 2014, the <a href="http://www.imf.org/external/np/fin/data/param_rms_mth.aspx">value of an SDR</a> is about US$1.49, £0.93 or A$1.70. Current SDR values for other currencies are also listed <a href="http://www.imf.org/external/np/fin/data/param_rms_mth.aspx">here</a>.</p> <h2>So what is your baggage worth?</h2> <p>In terms of baggage liability limits, the Warsaw Convention is of relatively little assistance to passengers.</p> <p>If your international travel is subject to Warsaw (for example, if you flew out of the United States on a one way ticket to Guatemala), liability for delayed, damaged or lost baggage is limited to 17 SDRs (about US$25.33, £15.81 or A$28.90) per kilogram per passenger for checked baggage and 332 SDRs (about US$494.68, £308.76 or A$564.40) per passenger for unchecked baggage.</p> <p>In contrast, a carrier is liable to pay far greater damages if the Montreal Convention applies.</p> <p>For any travel covered by Montreal, the carrier’s liability for baggage is limited to 1131 SDRs per passenger (US$1685.19, £1051.83 or A$1922.70), unless otherwise declared.</p> <p>The carrier is not liable for damages caused by delay if the carrier took all reasonable measures, or if it was impossible for it to take such measures.</p> <h2>Time limits on baggage claims</h2> <p>Time limits are imposed on making a claim for delayed, damaged or lost baggage. Any potential claims should be made to a carrier in writing within these specified limits.</p> <p>Article 26 of Warsaw provides that any complaint as to delay of baggage must be made at the latest within 21 days from the date the baggage was placed at the passenger’s disposal.</p> <figure class="align-right zoomable"></figure> <p>Similarly, under Article 31 of Montreal, a complaint must be made within 21 days of a passenger receiving their baggage.</p> <p>With respect to damaged baggage, under Warsaw, any claim must be made “forthwith” after the discovery of the damage and at most seven days from the date of receipt of the baggage. Montreal also gives passengers seven days from receipt of checked bags to report a damage claim.</p> <p>Neither convention imposes a time limit for reporting lost baggage claims. But it is advisable that you make your complaint as soon as possible.</p> <p>Warsaw does not state when baggage is considered “lost”, leaving it up to carriers to make that ruling. Under Montreal, baggage is only considered lost after 21 days or if the carrier admits that they have lost it.</p> <p>If a passenger fails to make a complaint within the specified times, the carrier will not be liable unless there has been fraud on the carrier’s part.</p> <h2>Insurance alternatives</h2> <p>If you are concerned that the contents of your baggage exceed the liability limits outlined above, you can make a special declaration of the value of your baggage prior to check-in and pay any additional fee (if required).</p> <p>In this case, the carrier will be liable to pay a higher amount, unless it is proved that the declared amount is greater than the actual value of your baggage.</p> <p>Alternatively, prior to travelling, check with your insurance company as to whether your travel insurance covers any excess from delayed, damaged or lost baggage.</p> <p>You might also want to <a href="http://www.icao.int/secretariat/legal/List%20of%20Parties/Mtl99_EN.pdf">check this list</a> to see whether the places you’re departing from and finally arriving at are parties to the Montreal Convention.

4 things you’re likely doing that are damaging your hearing

<p>Your hearing is a precious gift, so it’s important to take good care of your ears. We’ve got some advice on the things to avoid, and what you can do to protect your hearing.</p> <p><strong>Using cotton tips</strong></p> <p>Though they’re commonly used for the job, cotton tips should never be used to clean out your ears. In fact, no solid object should be put inside your ears. Cotton tips account for around four per cent of all ruptured eardrums. </p> <p>These innocuous-looking objects can also cause bleeding, scratch your ear canal, or trigger an infection. So put them down and step away. Instead, use a commercial ear cleaner, or even just a few drops of mineral oil, baby oil, or glycerine to soften the earwax.</p> <p><strong>Don’t wait and see</strong></p> <p>If your hearing in one or both ears suddenly disappears without cause, you need to go and see your doctor as soon as you can. It could be inflammation, infection, or a decrease in blood supply to the area. </p> <p>If you need treatment, you’ll likely need it immediately to have any hope of restoring your hearing.</p> <p><strong>Using eardrops without advice</strong></p> <p>There are many over-the-counter eardrops available to help with things like swimmer’s ear. But in extreme cases, these products can cause deafness. Before you use anything, including a home remedy, get your doctor to check that you don’t have a ruptured eardrum. </p> <p>Some people may be born that way, or have had surgery as a child, or suffered an injury. If the ingredients in these drops make their way inside your eardrum, it can cause a lot of pain, and permanent deafness.</p> <p><strong>Always protect your ears</strong></p> <p>It’s incredibly important to protect your ears from permanent damage. Tiny hairs inside your ears act as hearing receptors, and these can be broken by extremely loud noises. Once they’re gone, they don’t come back. </p> <p>So things like loud music, fireworks, machinery, and artillery are all risky to be around. The best thing you can do is cover up with earmuffs whenever you’re around these things – especially if it’s on a regular basis. For extra safety, use earplugs as well.</p> <p><em>Image credits: Shutterstock </em></p>

Britney Spears’ memoir is a reminder of the stigma and potential damage of child stardom

<p><em><a href="https://theconversation.com/profiles/jane-oconnor-1483447">Jane O’Connor</a>, <a href="https://theconversation.com/institutions/birmingham-city-university-920">Birmingham City University</a></em></p> <p>Britney Spears’ new memoir, The Woman in Me, illustrates once again the potential lifelong damage that can be caused by being a child star. Like many before her, including <a href="https://www.britannica.com/biography/Judy-Garland">Judy Garland</a> and <a href="https://www.britannica.com/biography/Michael-Jackson">Michael Jackson</a>, Spears was ushered into the dangerous terrain of childhood fame by the adults who were supposed to be protecting her, and was utterly unprepared to deal with the fallout.</p> <p>Spears’ <a href="https://www.bbc.co.uk/news/world-us-canada-53494405">father’s conservatorship</a>, controlling every aspect of her personal and professional life, was finally rescinded in 2021. She is now able to share the details of her extraordinary years in the limelight and beyond.</p> <p>From a sociological perspective, childhood is considered socially constructed. This means that there are specific ways of raising children which are socially and culturally defined. We discard these conventions surrounding the early years of life at our peril.</p> <p>The boundaries and rules around what is and is not acceptable during childhood, and the normal activities and institutions that shape the experience of being a child have developed over the centuries for a reason – to try and keep children safe from the harsh realities of the adult world.</p> <p>Being sexualised and valued for your appearance, being paid to work, having to deal with criticism and unwanted attention from strangers – these are all difficult aspects of growing up. Children and teens need careful support and guidance if they are to navigate safely into their adult lives and identities.</p> <p>The experience of childhood fame throws aside this social safety net for children in every possible way, and the consequences can be disastrous.</p> <h2>The price of child fame</h2> <p>From the earliest child stars of Hollywood’s golden age, through the television sitcoms and shows of the mid-20th century, the rise of the pop and film industries in the following decades and the burst in popularity of reality TV and talent shows of the early 21st century, <a href="https://www.tandfonline.com/doi/abs/10.1080/17482798.2011.584378">children have always featured</a>. Many have paid a heavy price for their often short period of fame.</p> <p>Sad stories of <a href="https://www.or-nc.com/why-do-child-stars-become-addicted-to-drugs/">drug and alcohol addiction</a>, <a href="https://www.hitc.com/en-gb/2022/11/02/uncle-fester-star-jackie-coogans-tragic-life-child-fortune-to-horror-crash">family disputes</a>, <a href="https://www.ranker.com/list/child-actors-who-became-criminals/nathan-gibso">criminal activity</a> and <a href="https://www.dailystar.co.uk/showbiz/us-showbiz/former-nickelodeon-star-drake-bells-29769568">toxic relationships</a> are frequently reported by the media. These reinforce the stereotypical “child star gone bad” and “too much too young” narratives that the wider public has come to expect.</p> <p>For example, stories abound of <a href="https://metro.co.uk/2020/02/11/macaulay-culkin-reveals-never-divorced-parents-emancipated-12222457/">Macaulay Culkin “divorcing” his controlling parents</a> and his difficulties transitioning into adult life, <a href="https://www.belfasttelegraph.co.uk/entertainment/film-tv/why-it-was-not-a-wonderful-life-for-macaulay-culkin-after-he-found-fame-in-the-hit-christmas-film-home-alone/37620091.html">feeling trapped</a> in the image of boyhood innocence of his most famous character, Kevin in the Home Alone movies.</p> <p><a href="https://books.google.co.uk/books?id=kSJ8XjTw10kC&amp;printsec=frontcover&amp;redir_esc=y#v=onepage&amp;q&amp;f=false">In her autobiography</a> actor Drew Barrymore has written about her casual acceptance at Hollywood parties and consumption of alcohol at a very young age, following her role in <a href="https://www.imdb.com/title/tt0083866/">E.T.</a> (1982) aged five.</p> <p>There is also the tragic life and death of <a href="https://www.theguardian.com/tv-and-radio/2010/may/29/gary-coleman-obituary">Gary Coleman</a>, cute kid star of the American sitcom <a href="https://www.imdb.com/title/tt0077003/">Diff'rent Strokes</a> (1978-1986).</p> <p>Coleman, who died at 42 following a history of <a href="https://nypost.com/2010/05/29/troubled-80s-child-star-gary-colemans-life-is-cut-short-at-42/#:%7E:text=In%202005%2C%20Coleman%20moved%20to,and%20%22wanted%20to%20die.%22">substance abuse</a> and <a href="https://www.salon.com/2010/05/28/gary_coleman_dies/">depression</a>, reported being <a href="https://www.theguardian.com/tv-and-radio/2010/may/29/gary-coleman-obituary">deeply humiliated</a> by people asking: “Didn’t you used to be …?” when he was working as a security guard at a supermarket as an adult.</p> <h2>Other possibilities</h2> <p>It’s important to note, however, that a difficult trajectory is not the experience of all child stars and former child stars. The actors from the Harry Potter films, for example, seem <a href="https://www.theguardian.com/film/2021/oct/22/the-not-so-cursed-child-did-harry-potter-mark-the-end-of-troubled-young-actors">largely to have transitioned well</a> into adult lives and careers – some in the spotlight, others not.</p> <p>And the new generation of famous children and teens such as <a href="https://www.gq.com/story/stranger-things-millie-bobby-brown">Millie Bobby Brown</a>, star of the Netflix show <a href="https://theconversation.com/stranger-things-is-the-upside-down-to-disneys-cute-and-cuddly-universe-83417">Stranger Things</a> (2016-present), seem more prepared for fame than their predecessors, in control of their images and identities via their own social media platforms and <a href="https://www.bbc.co.uk/news/world-44045291">potentially protected to some extent</a> from extreme sexualisation by the MeToo movement.</p> <p>Even so, Brown <a href="https://www.popbuzz.com/tv-film/news/millie-bobby-brown-birthday-instagram-post/">commented on her 16th birthday</a> that: “There are moments I get frustrated from the inaccuracy, inappropriate comments, sexualization, and unnecessary insults.”</p> <p>For Spears though, these were more than moments. She details in her memoir how the constant public scrutiny of her body and physical appearance, being valued for her sexuality and treated as a commodity have characterised her entire life.</p> <p>It is no wonder <a href="https://people.com/britney-spears-reveals-why-shaved-off-hair-in-2007-exclusive-8362494">she shaved her head</a> in 2007, a move interpreted by the media as her having “gone mad”, but in fact a powerful indication of her anger at being perceived as nothing more than a dancing sex-doll. As she writes in her memoir: "I knew a lot of guys thought long hair was hot. Shaving my head was a way of saying to the world: fuck you. You want me to be pretty for you? Fuck you. You want me to be good for you? Fuck you. You want me to be your dream girl? Fuck you."</p> <p>The sociologist Erving Goffman wrote about the stigma of having a “<a href="https://www.howcommunicationworks.com/blog/2020/12/16/what-is-stigma-explaining-goffmans-idea-of-spoiled-identity">spoiled identity</a>” whereby people carry with them the public shame of transgression or physical difference.</p> <p>Being a former child star can be stigmatising for many reasons, including being constantly compared to an ideal younger version of yourself and not having had a “normal” childhood or conventional family relationships.</p> <p>In this memoir, Britney attempts to face down that stigma and reclaim her identity and person-hood as an adult. In doing so, she demonstrates that it can be possible to leave the dangerous terrain of early fame behind – but the journey is a tough one.</p> <p><em><a href="https://theconversation.com/profiles/jane-oconnor-1483447">Jane O’Connor</a>, Reader in Childhood Studies, <a href="https://theconversation.com/institutions/birmingham-city-university-920">Birmingham City University</a></em></p> <p><em>Image credits: Getty Images / Instagram, </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Tourist accused of causing over $8,000 in damages to iconic Roman statue

<p>A 22-year-old German tourist has been accused of causing around €5,000 (A$8,400) in damages to the 16th-century Fountain of Neptune in the Piazza della Signoria, Italy. </p> <p>Surveillance footage obtained by the police allegedly show the tourist - who has not been named - climbing over the protective barrier around the monument in the early hours of Monday morning as he posed for a photo on the statue. </p> <p>His two friends, who stood outside of the barrier, took the photos of him and they all fled the scene when the alarm went off, according to city authorities.</p> <p>"According to the investigators' reconstruction, after 1 o'clock this morning the tourist, in Piazza della Signoria with two other friends, climbed over the fence of the Neptune Fountain and climbed onto the edge of the pool," the statement read. </p> <p>"With a jump he then climbed onto the horse's leg, reaching the base of the carriage and, after having some photos taken by his friends, he climbed down," they added.</p> <p>"During the descent he placed his foot again on the hoof, damaging it. As soon as the alarm went off, however, the young man had already managed to escape with the two others." </p> <p>The tourist will be charged under the city penal code that prohibits the "destruction, dispersion, deterioration, disfigurement, soiling or illicit use of cultural or landscape assets."</p> <p>He has been detained in Florence and could be fined and banned from entering the city if convicted. </p> <p>Image:<em> X (formerly Twitter)</em></p>

5 surprising factors damaging your heart

<p>It’s important to maintain heart health at all stages of life, but it becomes particularly crucial as we age – after all, the older you get, the older your heart becomes, too. And even though you might be taking all the right precautions (e.g. quitting smoking, eating a healthy diet, exercising regularly), you could be tarnishing your ticker without even realising it. Here are five things you didn’t know could negatively affect your heart health.</p> <p><strong>1. Damaged hearing</strong> – if you’ve spent much of your life working or living in noisy areas or regularly attending loud events (i.e. those rock concerts you frequented back in the day!), beware. A 2015 study found that people with high-frequency hearing loss in both years (most often due to prolonged exposure to high-decibel noise) were twice as prone to heart disease than those with normal hearing.</p> <p><strong>2. Air pollution</strong> – Have you been considering a sea or tree change? Now might be the time to do it. Researchers in 2011 discovered that exposure to traffic and air pollution is responsible for between 5 and 7 per cent of heart attacks around the world. Experts believe this may be due to an increase in arterial plaque build-up experienced by city-dwellers.</p> <p><strong>3. Sleep deprivation</strong> – A chronic lack of sleep increases production of adrenaline and cortisol (the stress hormone), which in turn increases your heart rate and blood pressure. In fact, one study found those who regularly had less than five hours of sleep were three times more at risk of heart attack than those who got between six and eight hours.</p> <p><strong>4. Excessive exercise</strong> – Believe it or not, but exercise could be putting you at risk of a heart attack – that is, if you’re doing too much vigorous exercise too often. Anything that causes strain can lead to dangerously high blood pressure – this means weightlifting and endurance sports (e.g. marathons) could be off the table. Stick to low-impact workouts like brisk walking, light weights and yoga.</p> <p><strong>5. Too much sitting</strong> – We’ve heard it all before – that sitting is bad for you – but you might not have realised just how bad it can be. According to a 2015 report, the average adult spends more than half of their waking hours sitting down, making them more likely to suffer or die from heart disease –even those who exercised an hour a day couldn’t combat this higher risk.</p> <p><em>Images: Getty</em></p>

Arctic Ocean could be ice-free in summer by 2030s, say scientists – this would have global, damaging and dangerous consequences

<p><a href="https://theconversation.com/profiles/jonathan-bamber-102567">Jonathan Bamber</a>, <em><a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>The Arctic Ocean could be ice-free in summer by the 2030s, even if we do a good job of reducing emissions between now and then. That’s the worrying conclusion of a new study in <a href="https://www.nature.com/articles/s41467-023-38511-8">Nature Communications</a>.</p> <p>Predictions of an ice-free Arctic Ocean have a long and complicated history, and the 2030s is sooner than most scientists had thought possible (though it is later than some had wrongly forecast). What we know for sure is the disappearance of sea ice at the top of the world would not only be an emblematic sign of climate breakdown, but it would have global, damaging and dangerous consequences.</p> <p>The Arctic has been experiencing climate heating <a href="https://theconversation.com/arctic-is-warming-nearly-four-times-faster-than-the-rest-of-the-world-new-research-188474">faster than any other part of the planet</a>.

In other words, it’s a big signal, one of the most stark and dramatic signs of fundamental change to the climate system anywhere in the world.</p> <p>As a consequence, there has been considerable effort invested in determining when the Arctic Ocean might first become ice-free in summer, sometimes called a “blue ocean event” and defined as when the sea ice area drops below 1 million sq kms. This threshold is used mainly because older, thicker ice along parts of Canada and northern Greenland is expected to remain long after the rest of the Arctic Ocean is ice-free. We can’t put an exact date on the last blue ocean event, but one in the near future would likely mean open water at the North Pole for the first time in <a href="https://www.nature.com/articles/nature10581">thousands of years</a>.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&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/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=712&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=712&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=712&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=895&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=895&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=895&amp;fit=crop&amp;dpr=3 2262w" alt="Annotated map of Arctic" /></a><figcaption><span class="caption">The thickest ice (highlighted in pink) is likely to remain even if the North Pole is ice-free.</span> <span class="attribution"><a class="source" href="https://nsidc.org/arcticseaicenews/2015/05/new-tools-for-sea-ice-thickness/">NERC Center for Polar Observation and Modelling</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <p>One problem with predicting when this might occur is that sea ice is notoriously difficult to model because it is influenced by both atmospheric and oceanic circulation as well as the flow of heat between these two parts of the climate system. That means that the climate models – powerful computer programs used to simulate the environment – need to get all of these components right to be able to accurately predict changes in sea ice extent.</p> <h2>Melting faster than models predicted</h2> <p>Back in the 2000s, an assessment of early generations of climate models found they generally <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2007GL029703">underpredicted the loss of sea ice</a> when compared to satellite data showing what actually happened. The models predicted a loss of about 2.5% per decade, while the observations were closer to 8%.</p> <p>The next generation of models did better but were <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2012GL052676">still not matching observations</a> which, at that time were suggesting a blue ocean event would happen by mid-century. Indeed, the latest <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-i/">IPCC climate science report</a>, published in 2021, reaches a similar conclusion about the timing of an ice-free Arctic Ocean.</p> <p>As a consequence of the problems with the climate models, some scientists have attempted to extrapolate the observational record resulting in the controversial and, ultimately, incorrect assertion that this would happen <a href="https://www.theguardian.com/environment/2016/aug/21/arctic-will-be-ice-free-in-summer-next-year">during the mid 2010s</a>. This did not help the credibility of the scientific community and its ability to make reliable projections.</p> <h2>Ice-free by 2030?</h2> <p>The scientists behind the latest study have taken a different approach by, in effect, calibrating the models with the observations and then using this calibrated solution to project sea ice decline. This makes a lot of sense, because it reduces the effect of small biases in the climate models that can in turn bias the sea ice projections. They call these “observationally constrained” projections and find that the Arctic could become ice-free in summer as early as 2030, even if we do a good job of reducing emissions between now and then.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&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/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=394&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=394&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=394&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=495&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=495&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=495&amp;fit=crop&amp;dpr=3 2262w" alt="Walruses on ice floe" /></a><figcaption><span class="caption">Walruses depend on sea ice.

As it dramatically reduces the amount of sunlight absorbed by the ocean, removing this ice is predicted to further accelerate warming, through a process known as a positive feedback. This, in turn, will make the Greenland ice sheet <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2014GL059770">melt faster</a>, which is already a major contributor to <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021RG000757">sea level rise</a>.</p> <p>The loss of sea ice in summer would also mean changes in <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/ccp6/">atmospheric circulation and storm tracks</a>, and fundamental shifts in ocean biological activity.

Travel Trouble

More than 100,000 tourists will head to Antarctica this summer. Should we worry about damage to the ice and its ecosystems?

<p>As the summer sun finally arrives for people in the Southern Hemisphere, more than 100,000 tourists will head for the ice. Travelling on one of more than 50 cruise ships, they will brave the two-day trip across the notoriously rough Drake Passage below Patagonia, destined for the polar continent of Antarctica. </p> <p>During the COVID summer of 2020-21, just 15 tourists on two yachts visited Antarctica. But now, tourism is back – and bigger than ever. This season’s <a href="https://iaato.org/wp-content/uploads/2022/06/ATCM44-IAATO-Overview.pdf">visitor numbers</a> are up more than 40% over the largest <a href="https://iaato.org/wp-content/uploads/2020/07/IAATO-on-Antarctic-visitor-figures-2019-20-FINAL.pdf">pre-pandemic year</a>. </p> <p>So are all those tourists going to damage what is often considered the last untouched wilderness on the planet? Yes and no. The industry is well run. Tourists often return with a new appreciation for wild places. They spend a surprisingly short amount of time actually on the continent or its islands. </p> <p>But as tourism grows, so will environmental impacts such as black carbon from cruise ship funnels. Tourists can carry in microbes, seed and other invasive species on their boots and clothes – a problem that will only worsen as ice melt creates new patches of bare earth. And cruise ships are hardly emissions misers.</p> <h2>How did Antarctic tourism go mainstream?</h2> <p>In the 1950s, the first tourists hitched rides on Chilean and Argentinian naval vessels heading south to resupply research bases on the South Shetland Islands. From the late 1960s, dedicated icebreaker expedition ships were venturing even further south. In the early 1990s, as ex-Soviet icebreakers became available, the industry began to expand – about a dozen companies offered trips at that time. By the turn of this century, the ice continent was receiving more than 10,000 annual visitors: Antarctic tourism had gone mainstream. </p> <p>What does it look like today? </p> <p>Most Antarctic tourists travel on small “expedition-style” vessels, usually heading for the relatively accessible Antarctic Peninsula. Once there, they can take a zodiac boat ride for a closer look at wildlife and icebergs or shore excursions to visit penguin or seal colonies. Visitors can kayak, paddle-board and take the polar plunge – a necessarily brief dip into subzero waters. </p> <p>For most tourists, accommodation, food and other services are provided aboard ship. Over a third of all visitors never stand on the continent. </p> <p>Those who do set foot on Antarctica normally make brief visits, rather than taking overnight stays. </p> <p>For more intrepid tourists, a few operators offer overland journeys into the continent’s interior, making use of temporary seasonal camp sites. There are no permanent hotels, and Antarctic Treaty nations recently <a href="https://documents.ats.aq/ATCM44/fr/ATCM44_fr001_e.pdf">adopted a resolution</a>against permanent tourist facilities. </p> <p>As tourists come in increasing numbers, some operators have moved to offer ever more adventurous options such as mountaineering, heli-skiing, underwater trips in submersibles and scuba diving.</p> <h2>Is Antarctic tourism sustainable?</h2> <p>As Antarctic tourism booms, some advocacy organisations have warned the impact may be unsustainable. For instance, the Antarctic and Southern Ocean Coalition <a href="https://www.asoc.org/campaign/responsible-tourism-and-shipping/">argues</a> cruise tourism could put increased pressure on an environment already under significant strain from climate change. </p> <p>In areas visited most by tourists, the snow has a <a href="https://theconversation.com/each-antarctic-tourist-effectively-melts-83-tonnes-of-snow-new-research-177597">higher concentration</a> of black carbon from ship exhaust, which soaks up more heat and leads to snow melt. Ship traffic also risks carrying <a href="https://www.pnas.org/doi/10.1073/pnas.2110303118">hitchhiking invasive species</a> into the Southern Ocean’s vulnerable marine ecosystems.</p> <p>That’s to say nothing of greenhouse gas emissions. Because of the continent’s remoteness, tourists visiting Antarctica have a <a href="https://www.tandfonline.com/doi/full/10.1080/09669581003653534">higher per capita carbon footprint</a>than other cruise-ship travellers. </p> <p>Of course, these impacts aren’t limited to tourism. Scientific expeditions come with similar environmental costs – and while there are far fewer of them, scientists and support personnel spend far more time on the continent. </p> <h2>Antarctic tourism isn’t going away – so we have to plan for the future</h2> <p>Are sustainable cruises an oxymoron? Many <a href="https://www.popsci.com/environment/why-cruise-ships-are-bad-for-the-environment/#:%7E:text=Studies%20have%20shown%20one%20cruise,in%20unhealthy%20levels%20of%20pollution.">believe so</a>. </p> <p>Through its sheer size, the cruise industry has created <a href="https://theconversation.com/time-to-rock-the-boat-cruise-ships-can-destroy-the-very-destinations-they-sell-to-us-55245">mass tourism</a> in new places and <a href="https://theconversation.com/overtourism-a-growing-global-problem-100029">overtourism</a> in others, generating unacceptable levels of crowding, disrupting the lives of residents, repurposing local cultures for “exotic” performances, damaging the environment and adding to emissions from fossil fuels. </p> <p>In Antarctica, crowding, environmental impact and emissions are the most pressing issues. While 100,000 tourists a year is tiny by global tourism standards – Paris had almost 20 million in 2019 – visits are concentrated in highly sensitive ecological areas for only a few months per year. There are no residents to disturb (other than local wildlife), but by the same token, there’s no host community to protest if visitor numbers get too high. </p> <p>Even so, strong protections are in place. In accordance with the Antarctic Treaty System – the set of international agreements signed by countries with an Antarctic presence or an interest – tourism operators based in those nations have to apply for permits and follow <a href="https://www.ats.aq/e/protocol.html">stringent environmental regulations</a>. </p> <p>To avoid introducing new species, tourists have to follow rules such as disinfecting their boots and vacuuming their pockets before setting foot on the ice, and keeping a set distance from wildlife. </p> <p>Almost all Antarctic cruise owners belong to the International Association of Antarctica Tour Operators, the peak body that manages Antarctic tourism. </p> <p>For the first time this year, operators have to report their <a href="https://iaato.org/antarctic-tour-operators-fuel-consumption-to-be-analysed-as-they-embark-on-climate-strategy/">overall fuel consumption</a> as part of IAATO’s efforts to make the industry more climate-friendly. Some operators are now using hybrid vessels that can run partly on electric propulsion for short periods, reducing carbon dioxide emissions.</p> <h2>Returning from the ice: the ambassador effect</h2> <p>Famed travel writer Pico Iyer <a href="https://www.nytimes.com/2022/11/17/t-magazine/travel-destinations-experiences.html?te=1&amp;nl=from-the-times&amp;emc=edit_ufn_20221127">recently wrote</a> of his experience in the deep south of the world. The visit, he said, “awakens you to the environmental concerns of the world … you go home with important questions for your conscience as well as radiant memories”. </p> <p>Iyer isn’t alone. This response is widespread, known in the industry as <a href="https://www.cambridge.org/core/journals/polar-record/article/what-and-who-is-an-antarctic-ambassador/4943D999A9D58BC00D1705C110075163">Antarctic ambassadorship</a>. As you’d expect, this is <a href="https://iaato.org/antarctic-ambassadors/antarctic-ambassadors/">strongly promoted</a> by tourism operators as a positive. </p> <p>Is it real? That’s contentious. Studies on links between polar travel and pro-environmental behaviour have yielded <a href="https://doi.org/10.1017/S0032247408007456">mixed results</a>. We are working with two operators to examine the Antarctic tourist experience and consider what factors might feed into a long-lasting ambassador effect. </p> <p>If you’re one of the tourists going to Antarctica this summer, enjoy the experience – but go with care. Be aware that no trip south comes without environmental cost and use this knowledge to make clear-eyed decisions about your activities both in Antarctica and once you’re safely back home.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/more-than-100-000-tourists-will-head-to-antarctica-this-summer-should-we-worry-about-damage-to-the-ice-and-its-ecosystems-192843" target="_blank" rel="noopener">The Conversation</a>. </em></p>

Alex Jones to pay eye-watering sum in damages

<p dir="ltr">Alex Jones, the host of far-right radio show InfoWars, has been ordered to pay a total of $US 49.3 million ($NZD 78.43 million) in damages for falsely claiming the 2012 Sandy Hook school shooting was a hoax.</p> <p dir="ltr">A Texas jury ruled that Jones pay $45.2 million in punitive damages, after awarding $4.1 million in compensatory damages the previous day, per <em><a href="https://www.bbc.com/news/world-us-canada-62444302" target="_blank" rel="noopener">BBC News</a></em>.</p> <p dir="ltr">Jones has repeatedly claimed that the shooting at Sandy Hook primary school, Connecticut, where 20 children and adults were killed was a “hoax” carried out by actors who opposed the Second Amendment right to bear firearms.</p> <p dir="ltr">Nail Heslin and Scarlett Lewis, the plaintiffs in the case and whose son died in the shooting, asked the court for $150 million, claiming they endured harassment and emotional distress as a result of his misinformation.</p> <p dir="ltr">Heslin told the court that Jones’ falsehoods had made his life “hell” and led to harassment and death threats from people who believed he had lied about his son’s death.</p> <p dir="ltr">The $4.1 million in compensatory damages were issued on Thursday to cover the actual costs incurred by the plaintiffs as a result of Jones’ defamation, including the private security they hired out of fear a Jones supporter may attack them during the trial.</p> <p dir="ltr">The following day’s $45.2 million are meant to deter Jones from repeating his offence.</p> <p dir="ltr">“We ask that you send a very, very simple message and that is: Stop Alex Jones,” a lawyer for the parents said in court on Friday.</p> <p dir="ltr">“Stop the monetisation of misinformation and lies. Please.”</p> <p dir="ltr">Lawyers representing Heslin and Lewis accused Jones of trying to hide evidence, arguing that he committed perjury by denying having sent any messages about the shooting - with one attorney revealing that Jones’ legal representative accidentally sent them two years of Jones’ text messages.</p> <p dir="ltr">“Did you know 12 days ago your attorneys messed up and sent me an entire digital copy of your entire cell phone with every text message you’ve sent for the past two years?” said attorney Mark Bankston, according to HuffPost.</p> <p dir="ltr">“And when informed did not take any steps to identify it as privilege?”</p> <p dir="ltr">"If I was mistaken, I was mistaken, you've got the text messages right there," Jones said.</p> <p dir="ltr">Despite his long-held position that the shooting was fake, Jones acknowledged that it was “100 percent real” in court.</p> <p dir="ltr">“I unintentionally took part in things that did hurt these people’s feelings, and I’m sorry for that,” Jones said.</p> <p dir="ltr">However, the radio host has continued to use his media platform to claim the case was rigged against him, with his InfoWars depicting a judge being consumed by flames.</p> <p dir="ltr">During his brief appearance in court, Jones was rebuked several times by the judge for lying under oath, including one moment where he was told: “This is not your show.”</p> <p dir="ltr">The trial is one of three brought against Jones by family members of the Sandy Hook victims, and comes after he has lost a series of defamation cases filed by parents by default after he failed to produce documents or testimony.</p> <p dir="ltr">But, this is the first trial where a jury agreed to award financial damages.</p> <p><span id="docs-internal-guid-71a17443-7fff-4a6b-001a-e0fe0b49116b"></span></p> <p dir="ltr"><em>Image: Getty Images</em></p>

<p dir="ltr">A tourist has learned the hard way to not interfere with the Queen’s guards, after she copped an earful from a guard for grabbing his horse’s reins.</p> <p dir="ltr">During a recent trip to London, the woman went to pose for a photo next to the guard and his horse when her hand went to reach towards the animal, drawing the guard’s attention.</p> <p dir="ltr">When she then touched the reins, he reacted by yelling with authority from atop his horse.</p> <p dir="ltr">“Stand back from the Queen’s lifeguard, don’t touch the reins!” he yells.</p> <p dir="ltr">A clip of the incident was shared by the woman’s step-son Ethan on <a href="https://www.tiktok.com/@phigs_/video/7116598758816763141?is_from_webapp=1&amp;sender_device=pc&amp;web_id=7112642336690570754" target="_blank" rel="noopener">TikTok</a>, with the caption, “We will never return to London after this incident” and text across the footage reading, “Queens Guard Verbally Attacks My Step mum [sic]”.</p> <p><span id="docs-internal-guid-d6005c55-7fff-02e7-69ff-48d842020c82"></span></p> <p dir="ltr">Though Ethan commented the guard as a “rather angry little man”, a large number of commenters sided with the guard, arguing that he has an important job to do and that working animals like his horse shouldn’t be touched while on duty.</p> <p dir="ltr"><img src="https://oversixtydev.blob.core.windows.net/media/2022/07/queen-guard-horse.jpg" alt="" width="640" height="360" /></p> <p dir="ltr"><em>Image: TikTok</em></p> <p dir="ltr">“It’s not Disney they are working horses and serving army,” one person said.</p> <p dir="ltr">“Serves her right, you aren’t allowed to touch the guard,” another wrote.</p> <p dir="ltr">“They have a job, just don’t go near them,” a third added.</p> <p dir="ltr">British followers were particularly quick to defend his actions and respond to their decision not to return to London.</p> <p dir="ltr">“The whole of London is so upset that you won’t be returning we’re all begging you to come back,” one person said.</p> <p dir="ltr">“Every British person I know knows you don’t touch them, or is she one of them ones that would put her hand in the blender,” another wrote.</p> <p dir="ltr">As some commenters pointed out, the horse’s reins are connected to the animal’s mouth - which is quite sensitive - and tugging on the reins could spook the animal, causing it to bite her or unseat the guard.</p> <p dir="ltr">Others compared interfering with or touching the guard and his horse to doing the same to a guide dog, while <em><a href="https://honey.nine.com.au/royals/queens-guard-member-yells-at-tourist-for-touching-horse-reins-tiktok/98f85c75-54a9-4b5e-a9a7-146c4a6699a8" target="_blank" rel="noopener">9Honey</a></em> royal reporter Natalie Oliveri explained that as a rule, you shouldn’t touch animals that are on-duty.</p> <p dir="ltr">"Also, as a general rule tourists should be respectful of any member of Her Majesty's guard while they are on duty – they are there for an important reason and no one should try to interfere with that,” Oliveri said.</p> <p dir="ltr">She explained that it’s also best not to speak to members of the Queen’s Guard while they’re on duty, and that you shouldn’t expect a response from them.</p> <p dir="ltr">"If you would like a photo, perhaps it's best to stand at a respectable distance and never interfere with their job,” she added.</p> <p dir="ltr"><span id="docs-internal-guid-f70ace45-7fff-42a5-8c43-e349bd54bbfc"></span></p> <p dir="ltr"><em>Images: TikTok</em></p>

The real reason you want your ears to pop on a plane

<p dir="ltr">An airline pilot has revealed one of the most common questions she gets asked and it has to do with ear popping. </p> <p dir="ltr">It is a commonly known fact that there is nothing more annoying than having to deal with painful ears on a flight. Blocked ears occur when the plane takes off or starts to descend as the air pressure changes rapidly.</p> <p dir="ltr">It may not be as bad for some but others will find their Eustachian tube – the narrow passage connected to the middle ear - often can’t react fast enough, which causes the symptoms of aeroplane ear. </p> <p dir="ltr">US-based Boeing 737 co-pilot Morgan, who is known for her flight-related content on TikTok, shared a clip explaining why you want your ears to pop on a plane. *embed tweet</p> <p dir="ltr">“Trust me when I say you want your ears to pop,” she began the clip.</p> <p dir="ltr">The aviation TikTok star who has over 12 million likes on her videos, said if the pressure is building up and you’re getting one big painful pop, there are a couple of things you can do to pop your ears a little bit sooner.</p> <blockquote class="tiktok-embed" style="max-width: 605px; min-width: 325px;" cite="https://www.tiktok.com/@almostcaptainmorgan/video/7111430582608989482" data-video-id="7111430582608989482"> <section><a title="@almostcaptainmorgan" href="https://www.tiktok.com/@almostcaptainmorgan" target="_blank" rel="noopener">@almostcaptainmorgan</a> Reply to @ladyhawkuk Tips and tricks from an airline pilot if your ears pop when you fly! <a title="airlinepilot" href="https://www.tiktok.com/tag/airlinepilot" target="_blank" rel="noopener">#airlinepilot</a> <a title="traveltiktok" href="https://www.tiktok.com/tag/traveltiktok" target="_blank" rel="noopener">#traveltiktok</a> <a title="flyingtips" href="https://www.tiktok.com/tag/flyingtips" target="_blank" rel="noopener">#flyingtips</a> <a title="traveltips" href="https://www.tiktok.com/tag/traveltips" target="_blank" rel="noopener">#traveltips</a> <a title="♬ original sound - Morgan" href="https://www.tiktok.com/music/original-sound-7111430549822294830" target="_blank" rel="noopener">♬ original sound - Morgan</a></section> </blockquote> <p dir="ltr">“Yawning, talking, eating, chewing gum, swallowing, really anything that’s going to move your jaw is going to help activate your Eustachian tube and pop your ears,” she said.</p> <p dir="ltr">“If none of those work, you can do something called a Valsalva manoeuvre, which is where you pinch your nose and blow.”</p> <p dir="ltr">She said don’t blow harder if your ears don’t clear as “this can lead to bigger issues”.</p> <p><span id="docs-internal-guid-0683e841-7fff-ce3f-3c0f-3ea7a02e8418"></span></p> <p dir="ltr">Morgan shares if you’re ever in a situation where the pressure is really building up and your ears just aren’t popping, “always travel with some Afrin nasal spray”.

Why the "just one drink a day" excuse no longer cuts it

<p dir="ltr">According to a new study, those who have one standard drink a day are putting themselves at risk of permanent brain damage.</p> <p dir="ltr">The study of almost 21,000 people, published in the PLOS Medicine journal, found that consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain.</p> <p dir="ltr">More iron in the brain is also linked to Alzheimer's and Parkinson's disease and is a potential mechanism for alcohol-related cognitive decline.</p> <p dir="ltr">The participants reported their own alcohol consumption, and their brains were scanned using magnetic resonance imaging (MRI).</p> <p dir="ltr">Of those participants, 7,000 of them also had MRIs on their livers imaged to see the levels of systemic iron.</p> <p dir="ltr">They were also required to complete a few tasks to assess their cognitive and motor function.</p> <p dir="ltr">The participants' average age was 55 years old and 48.6 per cent were female.</p> <p dir="ltr">Anya Topiwala of the University of Oxford, United Kingdom, and her colleagues found that alcohol consumption above seven units per week led to higher iron levels in basal ganglia - the part of the brain that helps with movement.</p> <p dir="ltr">“Markers of higher basal ganglia iron associated with slower executive function, lower fluid intelligence, and slower reaction times,” the study reported.</p> <p dir="ltr">“Iron accumulation in some brain regions was associated with worse cognitive function.”</p> <p dir="ltr">They concluded that moderate alcohol consumption is associated with higher iron levels in the brain.</p> <p dir="ltr"><em>Image: Shutterstock</em></p>

Duchess of Cambridge wears $3.80 earrings for her first royal engagement of the year

<p><em>Image: 9Honey </em></p> <p>The Duchess of Cambridge stepped out showcasing her signature mix of high and low end fashion in a chic return to work for the new year.</p> <p>Kate Middleton visited The Foundling Museum in London on Wednesday wearing a teal blue coat over the top of an all-navy ensemble. </p> <p>But her standout accessory was the royal's $3.80 gold earrings from UK store Accessorize.</p> <p>The mini hammered doorknocker hoop earrings from the high street chain (similar to Lovisa) were originally £7 ($13.20) but were in the recent sale, dropping in price to £2.10 ($3.80) — needless to say, they're now sold out.</p> <p>The only other jewels that Kate could be seen wearing was her heirloom sapphire and diamond engagement ring, which previously belonged to Princess Diana, and her wedding band.</p> <p>The Duchess, who celebrated her 40th birthday earlier this month, wasn't just cost-efficient in her jewellery department. Even the tailored blue coat has been seen before, with the Duchess last wearing it in January 2020, during a visit to LEYF Stockwell Gardens Nursery &amp; Pre-School in London.</p> <p>The Duchess also sported a turtle neck knit and navy suede heels, both of which are understood to be items worn to previous engagements and events.</p> <p>Kate's return to work for the new year wouldn't be complete without her signature bouncy blowdry, which bobbed as the royal arrived at The Foundling Museum with husband Prince William.</p>

Space travel may prompt cartilage damage

<p>Space travel may be bad for your joints, research indicates.</p> <p><span style="font-family: inherit;">Mice that spent a month aboard a Russian spacecraft showed early signs of cartilage breakdown, suggesting that the reduced biomechanical forces in space impact on the musculoskeletal system.</span></p> <p><span style="font-family: inherit;">And while it’s too early to translate their finding to humans, researchers from the Henry Ford Hospital in Detroit, US, say the evidence was “clear-cut”.</span></p> <p><span style="font-family: inherit;">“We believe this degradation is due to joint unloading caused by the near lack of gravity in space,” says lead author Jamie Fitzgerald, the hospital’s head of musculoskeletal genetics. “If this were to happen to humans, given enough time, it would lead to major joint problems.” </span></p> <p><span style="font-family: inherit;">With funding from NASA, Fitzgerald and colleagues analysed molecular changes in the cartilage of mice that spent 30 days in animal research enclosures aboard an unmanned Russian Bion-M1 spacecraft in 2013. This included performing tissue stains and gene expression studies on the cartilage. The results were compared to mice observed on Earth during the same period.</span></p> <p><span style="font-family: inherit;">Video footage shows the mice floating around in their enclosure during the day, then at night struggling to climb over each other and hang onto the grate inside the enclosure. </span></p> <p><span style="font-family: inherit;">Fitzgerald says the resultant cartilage breakdown was consistent with changes associated with osteoarthritis. In comparison, the mice on Earth showed no discernible cartilage degradation.</span></p> <p><span style="font-family: inherit;">“When there’s no gravity pulling down on the cartilage, it’s not able to maintain its structure, its integrity,” he says. “On Earth, every time you take a step to walk, you’re loading that cartilage. In space, there’s very little of that.”</span></p> <p><span style="font-family: inherit;">With plans to send humans to Mars, NASA is obviously interested to know what precautions it may need to take to protect human knees. </span></p> <p><span style="font-family: inherit;">“You may have some payload specialists and experienced pilots who already have some degree of pre-symptomatic cartilage damage at the time of their flight,” Fitzgerald says. </span></p> <p><span style="font-family: inherit;">“Because cartilage in humans doesn’t readily repair, the return to Earth could potentially bring long-term health problems.”</span></p> <p><span style="font-family: inherit;">The <a rel="noopener" href="https://www.nature.com/articles/s41526-019-0063-6" target="_blank">study</a> is published in the journal npg Microgravity. </span></p> <div class="newsletter-box"> <div id="wpcf7-f6-p25312-o1" class="wpcf7"> <p style="display: none !important;"> </p> <p><!-- Chimpmail extension by Renzo Johnson --></p> </div> </div> <p><!-- Start of tracking content syndication.

How do pigeons find their way home? We looked in their ears with a diamond-based quantum microscope to find out

<p>Homing pigeons are known for their uncanny ability to find their way home – navigating complex and changing landscapes. In fact, they do this so well they were used as a source of secure communication more than 2,000 years ago.</p> <p>Julius Caesar <a href="https://www.asor.org/anetoday/2017/11/not-just-birds">reportedly sent</a> news of his conquest of Gaul back to Rome via pigeons, <a href="https://www.ft.com/content/255b75e0-c77d-11e2-be27-00144feab7de">as did Napoleon Bonaparte</a> following his defeat by England in the 1815 Battle of Waterloo.</p> <p>We know pigeons use visual cues and can navigate based on landmarks along known travel routes. We also know they have a magnetic sense called “magnetoreception” which lets them navigate using Earth’s magnetic field.</p> <p>But we don’t know exactly <em>how</em> they (and other species) do this. In <a href="https://www.pnas.org/cgi/doi/10.1073/pnas.2112749118">research</a> published today in the Proceedings of National Academy of Sciences, my colleagues and I tested a theory that attempts to link magnetoreception in homing pigeons with tiny lumps of iron-rich material found in their inner ears.</p> <p>By using a new kind of magnetic microscope, we confirmed this isn’t the case. But the technology has opened the door for us to investigate the phenomenon in several other species.</p> <h2>The current hypotheses</h2> <p>Scientists have spent decades exploring the possible mechanisms for magnetoreception. There are currently two mainstream theories.</p> <p>The first is a vision-based “free-radical pair” model. Homing pigeons and other migratory birds have proteins in the retina of their eyes called “cryptochromes”. These produce an electrical signal that <a href="https://www.nature.com/articles/s41586-021-03618-9">varies depending on the strength</a> of the local magnetic field.</p> <p>This could potentially allow the birds to “see” Earth’s magnetic field, although scientists have yet to confirm this theory.</p> <p>The second proposal for how homing pigeons navigate is based on lumps of magnetic material inside them, which may provide them with a magnetic particle-based directional compass.</p> <p>We know magnetic particles are found in nature, in a group of bacteria called <a href="https://theconversation.com/magnetic-bacteria-and-their-unique-superpower-attract-researchers-100720">magnetotactic bacteria</a>. These bacteria produce magnetic particles and orient themselves along the Earth’s magnetic field lines.</p> <p>Scientists are now looking for magnetic particles in a range of species. Potential candidates <a href="https://link.springer.com/article/10.1007%2Fs00114-007-0236-0">were found</a> in the upper beak of homing pigeons more than a decade ago, but <a href="https://www.nature.com/articles/nature11046">subsequent work</a> indicated these particles were related to iron storage and not magnetic sensing.</p> <h2>A peek inside a pigeon’s ear</h2> <p>The new search is now underway in the inner ear of pigeons, where iron particles known as “cuticulosomes” <a href="https://www.sciencedirect.com/science/article/pii/S0960982213004338">were first identified</a> in 2013.</p> <p>Single cuticulosomes have been located within distinct regions in the pigeon inner ear where other known sensory systems exist (such as for hearing and balancing during flight). In theory, if there were a magnetic sensing system in pigeons, it should be located close to other sensory systems.</p> <p>But to determine whether iron cuticulosomes can act as magnetoreceptors in pigeons, scientists need to determine their magnetic properties. This is no mean feat, since cuticulosomes are 1,000 times smaller than a grain of sand.</p> <p>What’s more is they are only found in 30% of the hair cells within the inner ear, making them difficult to identify and characterise.</p> <p><a href="https://images.theconversation.com/files/431870/original/file-20211115-6434-uzv76r.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/431870/original/file-20211115-6434-uzv76r.jpeg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Diagram showing a homing pigeon's inner ear, with labels for hair cells and magnetic particles." /></a> <span class="caption">We conducted quantum magnetic imaging of iron-organelles in the pigeon inner ear.</span> <span class="attribution"><span class="source">Robert W de Gille</span>, <span class="license">Author provided</span></span></p> <p>To tackle this problem our group at the University of Melbourne, together with colleagues from Vienna’s Institute of Molecular Pathology and the Max Planck Society in Bonn, turned to a new imaging technology to explore the magnetic properties of iron cuticulosomes in the pigeon inner ear.</p> <p>We developed a magnetic microscope that uses diamond-based sensors to visualise delicate magnetic fields emanating from tiny magnetic particles.</p> <h2>Disproving the theory</h2> <p>We carefully studied thin sections of the pigeon inner ear placed directly onto the diamond sensors. By applying magnetic fields of varying strengths to the tissue, we were able to gauge the magnetic susceptibility of single cuticulosomes.</p> <p>Our results showed the magnetic properties of the cuticulosomes were not strong enough for them to act as a magnetic particle-based magnetoreceptor. In fact, the particles would need to be 100,000 times stronger to activate the sensory pathways required for magnetoreception in pigeons.</p> <p>However, despite the search for the elusive magnetoreceptor coming up short, we are extremely excited by the potential of this magnetic microscope technology.</p> <p>We hope to use it study a host of magnetic candidates across a variety of species including rodents, fish and turtles. And by doing so we can focus not only on cuticulosomes, but a range of other potentially magnetic particles.<!-- Below is The Conversation's page counter tag.
