How extreme dieting can affect bone health

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>In a recent Instagram post, the actor Jameela Jamil revealed she has poor bone density, despite only being in her 30s. Jamil blamed this finding on 20 years of dieting – urging her followers to be aware of the harms diet culture can do to your health.</p> <p>Bone density is important for many reasons, primarily because it acts as a reservoir for many of the important minerals our bones need to function well. Many factors can affect your bone density – and as Jamil has pointed out, diet is one component that has a significant effect on bone health.</p> <p>Bone is a living tissue. This means our skeleton <a href="https://www.sciencedirect.com/science/article/abs/pii/S1521690X08000869">grows and remodels itself</a> according to the stresses and strains it’s put under. Everything from fractures to exercise require our bones to change their shape or density. This is why a weightlifter’s skeleton is <a href="https://link.springer.com/article/10.1007/BF00298721">much denser</a> than a marathon runner’s.</p> <p>The biggest skeletal changes we experience happen in our younger years. But bones keep changing throughout our lives depending on how active we are, what our diet consists of, and if we’ve suffered an injury or disease.</p> <p>Bones are <a href="https://www.niams.nih.gov/health-topics/what-bone">made of proteins</a>, such as collagen, as well as minerals – largely calcium. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK430714/">key mineral</a> for us, as it keeps our bones and teeth strong and helps repair and rebuild any injured bones.</p> <p>But other minerals and vitamins are also important. For example, vitamin D supports calcium, playing a key role in <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2761808">bone mineralisation</a>. This is where calcium <a href="https://www.ncbi.nlm.nih.gov/books/NBK279023/">combines with phosphate</a> in our bones to create the mineral crystal <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7264100/">hydroxyapatite</a>. This crystal is crucial to our bone mineral density (also known as “bone mass”), as it helps bones remodel and maintain their structural strength.</p> <p><a href="https://www.nhs.uk/conditions/dexa-scan/">Dexa scans</a> – the type of scan Jamil referred to in her post – can measure the density of these crystals in bones. The <a href="https://theros.org.uk/information-and-support/osteoporosis/scans-tests-and-results/bone-density-scan-dxa/">more hydroxyapatite crystals</a> detected, the healthier the bones are.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.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/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=3 2262w" alt="The interior of bones, showing four depictions of bone density – from healthy to severe osteoporosis." /><figcaption><span class="caption">The more crystals detected, the better your bone density.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-illustration/osteoporosis-4-stages-one-picture-3d-524364046">Crevis/ Shutterstock</a></span></figcaption></figure> <p>We hit peak bone mineral density in our <a href="https://pubmed.ncbi.nlm.nih.gov/35869910/">late teens and early 20s</a>, when our body has grown to full size and our metabolism is working its best. From here, it’s possible to maintain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">stable bone mass</a> into your late 30s for women and early 40s for men, with the right diet and activity. But after this point, it begins to decline.</p> <h2>Bone density</h2> <p>We accrue calcium over many years. It initially comes from our mother, then later from our diet. Our body accrues calcium so it can adapt to times when calcium demand is greater than what we can get from our diet – such as during pregnancy, when the foetus needs calcium to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3355895/">build its own bones</a>.</p> <p>However, relying solely on this skeletal calcium reserve can’t be sustained for lengthy or repeated periods, because of how long it takes to be replenished. This is why diet is so important for bone density – and why a poor diet can cause extreme damage, especially when certain food groups or minerals are consistently left out.</p> <p>For instance, studies have shown consuming soft drinks, (<a href="https://pubmed.ncbi.nlm.nih.gov/17023723/">particularly cola</a>), more than four times a week is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071508/">lower bone density</a> and increased fracture risk. This is true even after adjusting for many other variables that affect bone density.</p> <p>These carbonated and energy drinks contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2966367/">varying levels of vitamins</a> – often with none of the minerals, including calcium, that the body needs to function optimally. This causes the body to draw on its reserves if calcium isn’t being delivered elsewhere in the diet.</p> <p>Diets high in added sugar can also have a detrimental affect on the skeleton. Excess sugar causes inflammation and other physiological changes, such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9471313/">obesity</a>. Consuming high amounts of sugar is linked with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2748414/">reduced calcium intake</a>, especially in children who substitute milk for sugary drinks. Excess sugar consumption also causes the body to <a href="https://jps.biomedcentral.com/articles/10.1007/s12576-016-0487-7">excrete excess calcium</a>, instead of reabsorbing it in the kidney as the body normally would.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/25491765/">Low- and high-fat diets</a> have also been associated with increased risk of <a href="https://www.nhs.uk/conditions/osteoporosis/">osteoporosis</a> (a condition that weakens bones) in women – though larger studies are needed to better understand the effects of removing whole food groups on bone health.</p> <p><a href="https://www.nhs.uk/mental-health/conditions/anorexia/overview/">Anorexia nervosa</a> also has a significant affect on <a href="https://pubmed.ncbi.nlm.nih.gov/30817009">bone density</a> – affecting a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">majority of people</a> with the condition.</p> <p>Low bone mineral density – especially in the spine – puts people with anorexia at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6959847/">increased risk of fractures</a> because their bone thickness is reduced, increasing the likelihood of developing osteoporosis, which is associated with increased fractures.</p> <p>Anorexia in young adulthood is particularly challenging. This is the stage where the skeleton is building itself to reach peak <a href="https://pubmed.ncbi.nlm.nih.gov/15574617/">bone mass</a>, so it’s depositing calcium at a record pace. When diet is insufficient and the body already starts drawing on its mineral reserves, there’s a potential that the bone density or calcium reserves in the body will never be optimal – increasing fracture risk for the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6746661/">rest of that person’s life</a>.</p> <h2>Can bone health be fixed?</h2> <p>Optimal bone health starts in utero, but our prepubescent years are key to <a href="https://pubmed.ncbi.nlm.nih.gov/26884506/">setting our skeleton up</a> for later life. People who are behind the curve in early life may have difficulty achieving their peak, as poor bone mineral density can affect everything from our appetite to how efficient our gastrointestinal tract is at absorbing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6971894/">important nutrients</a> (including calcium). Supplements have a limited effect because our body can only absorb a set amount of any <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8746734/">vitamin or mineral at a time</a>.</p> <p>While it’s possible to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5684300/">limit some of the decline</a> in bone density that naturally happens as we age, some of the choices we make – such as not consuming enough calcium – can accelerate the decline. Biological sex also has a significant impact on our bone health in old age – with post-menopausal women at greater risk of osteoporosis because they <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5643776/">produce less oestrogen</a>, which helps keep the cells that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3424385">degrade bone</a> in check.<!-- Below is The Conversation's page counter tag.

It’s extremely hot and I’m feeling weak and dizzy. Could I have heat stroke?

<p><em><a href="https://theconversation.com/profiles/lily-hospers-1060107">Lily Hospers</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/james-smallcombe-1412548">James Smallcombe</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ollie-jay-114164">Ollie Jay</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Australia is braced for a hot, dry summer. El Nino is back, and this year it will occur alongside an <a href="https://www.abc.net.au/news/2023-08-22/positive-indian-ocean-dipole-to-coincide-with-el-nino/102756378">Indian Ocean dipole</a>, a climate pattern which will further amplify this hot and dry effect.</p> <p>Hot weather can place great stress on our bodies. When the environmental conditions exceed the limit at which we can adequately cope, we can suffer from heat-related illnesses.</p> <p>Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke.</p> <h2>What are the signs and symptoms?</h2> <p>If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness.</p> <p>Mild <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">symptoms of heat exhaustion</a> can often be treated at home by reducing your levels of physical activity, finding shade, removing excess clothing, hydrating with water and perhaps even taking a cool shower.</p> <p>If left unchecked, heat exhaustion can progress to the far more serious condition of heat stroke, where your core temperature climbs upwards of 40°C. <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/heat-related-illness.aspx">Symptoms</a> can develop rapidly and may include confusion, disorientation, agitation, convulsions, or it could even result in a coma.</p> <p>Heat stroke is a medical emergency and requires urgent treatment. Call an ambulance and start rapid, aggressive cooling by immersing the person in cold water (such as a cold bath). If this isn’t possible, apply ice packs to their neck, armpits and groin and cover the skin with lots of cool water.</p> <p>When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second.</p> <h2>Why do we overheat?</h2> <p>Environmental conditions play an important role in determining our heat stress risk. If the air temperature, humidity and levels of sun exposure are high, we are much more likely to dangerously overheat.</p> <p>When the body gets hot, the heart pumps more warm blood to our skin to help lose heat. As air temperature rises, this way of shedding heat becomes ineffective. When air temperature is higher than the temperature of the skin (normally around 35°C), we start gaining heat from our surroundings.</p> <p>Sweating is by far our most effective physiological means of keeping cool. However, it is the <em>evaporation</em> of sweat from our skin that provides cooling relief.</p> <p>When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates.</p> <p>Our physical activity levels and clothing also impact heat stress risk. When we move, our bodies generate metabolic heat as a by-product. The more intense physical activity is, the more heat we must lose to avoid dangerous rises in core temperature.</p> <p>Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool.</p> <h2>Who is most vulnerable in the heat?</h2> <p>Some people <a href="https://www.health.nsw.gov.au/environment/beattheheat/Pages/people-most-at-risk.aspx">are at greater risk</a> of developing heat illness than others. This can result from physiological limitations, such as a decreased capacity to sweat, or a reduced capacity to adapt our behaviour. When these two risk factors coincide, it’s a perfect storm of vulnerability.</p> <p>Take, for example, an elderly outdoor agricultural worker. Being aged over 60, their physiological capacity to sweat is reduced. The worker may also be wearing heavy safety clothing, which may further limit heat loss from the body. If they don’t slow down, seek shelter and adequately hydrate, they become even more vulnerable.</p> <p>When a person dies of heat stroke – which is relatively easy to diagnose – heat will be listed as a cause of death on a death certificate. Between 2001 and 2018 in Australia, 473 heat-related deaths were <a href="https://www.sciencedirect.com/science/article/pii/S2212420921006324">officially reported</a>.</p> <p>However, the true association between heat and death is thought to be far greater, with an <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(20)30100-5/fulltext">estimated 36,000 deaths</a> in Australia between 2006 and 2017.</p> <p>This is because most people who die during extreme heat events do not die from heat stroke. Instead, they they die of <a href="https://www.nejm.org/doi/full/10.1056/nejm199607113350203">other medical complications</a> such as cardiovascular or renal collapse, as additional strain is placed on essential organs such as the heart and kidneys.</p> <p>People with underlying health conditions are more likely to succumb to heat-associated complications before they develop critical core temperature (over 40°C) and heat stroke.</p> <p>In such cases, while the additional physiological strain imposed by the heat probably “caused” the death, the official “cause of death” is often listed as something else, such as a heart attack. This can make understanding the true health burden of extreme heat more difficult.</p> <h2>How to stay safe in the heat</h2> <p>Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

4 ways to support someone with dementia during extreme heat

<p><em><a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Our ability to adapt our behaviour to changes in temperature takes a significant amount of thought and decision making. For example, we need to identify suitable clothing, increase our fluid intake, and understand how to best keep the house cool.</p> <p>A person with dementia may find some or all these things challenging. These and other factors mean, for someone with dementia, extreme heat <a href="https://pubmed.ncbi.nlm.nih.gov/31520832/#:%7E:text=Conclusion%3A%20Heatwaves%20increased%20the%20risk,heat%2Drelated%20Alzheimer's%20disease%20burden.">can be deadly</a>.</p> <p>But as the temperature rises, friends, relatives and carers can help.</p> <h2>El Niño means there are challenges ahead</h2> <p>The recent declaration of <a href="https://www.abc.net.au/news/2023-09-19/bureau-of-meteorology-el-nino-blog/102875154">another El Niño</a> means we need to think about how we can best support those more vulnerable to be safe during the warmer months.</p> <p>Extreme heat and bushfires bring unique challenges for someone with dementia.</p> <p>Bushfires have a significant impact on older people’s mental health. But they generally <a href="https://www.health.act.gov.au/sites/default/files/2023-03/PATH_Impact%20of%202019-20%20Bushfires%20on%20a%20Cohort%20of%20Older%20Adults_REPORT_V3_0.pdf">bounce back</a> quickly.</p> <p>However, for someone with dementia, extreme heat can lead to a <a href="https://www.sciencedirect.com/science/article/pii/S0013935119305110">significant deterioration</a> in their overall health and they may not recover.</p> <p>Emergency evacuations can also be confusing and distressing for a person with dementia, so it is important to think ahead.</p> <h2>Why are people with dementia more at risk?</h2> <p>Dementia can affect the parts of the brain that help <a href="https://academic.oup.com/brain/article/138/11/3360/332653?login=true">regulate</a> our body temperature. Some <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243665">medications</a> can also increase someone’s sensitivity to heat.</p> <p>Problems with memory and thinking associated with dementia <a href="https://www.alzheimers.org.uk/get-support/daily-living/drinking-hydration">means</a> remembering to drink or communicating you are thirsty can be challenging.</p> <p>Heat can affect everyone’s mood. But if someone with dementia becomes dehydrated this can <a href="https://www.alzdiscovery.org/cognitive-vitality/blog/can-dehydration-impair-cognitive-function">increase</a> confusion and agitation, making it harder for them to know how to cool down.</p> <p>A person with dementia can also wander and become lost, which can be dangerous in extreme heat.</p> <h2>4 ways to support someone with dementia</h2> <p><strong>1. Avoid dehydration and heatstroke</strong></p> <p>Try to avoid dehydration by encouraging someone to drink throughout the day. It’s better to have <a href="https://pubmed.ncbi.nlm.nih.gov/31769256/">small amounts</a> of liquid regularly instead of a large amount all at once. Little and often will help maximise hydration while avoiding sudden trips to <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/dementia-continence-issues#causes-of-incontinence-in-people-with-dementia">the bathroom</a>.</p> <p>Try to offer different types of drinks, or ice blocks. Placing drinks in sight can help as a reminder to drink. Choose foods with a high liquid content, such as fruit, salads, cool broths and yoghurt.</p> <p>Look out for <a href="https://www.nia.nih.gov/health/hot-weather-safety-older-adults#:%7E:text=Signs%20of%20heat%20stroke%20are,as%20under%20shade%20or%20indoors.">signs of heatstroke</a>, such as increased confusion beyond what the person would usually experience. Heatstroke may be more difficult to spot in someone living with dementia so it is important to check in when possible and to help them cool down if needed.</p> <p><strong>2. Cool the home</strong></p> <p>Try to modify their home to make it easier to stay cool. Some air-conditioners have complex settings so make sure the temperature is set appropriately and the person with dementia knows how to use the controls.</p> <p>It is important to keep blinds and curtains shut where possible to reduce heat. However, ensure the <a href="https://www.scie.org.uk/dementia/supporting-people-with-dementia/dementia-friendly-environments/lighting.asp">lighting is adequate</a> to avoid falls.</p> <p>Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available.</p> <p><strong>3. Think about communications early</strong></p> <p>If someone with dementia lives alone, consider how you will maintain contact in an emergency.</p> <p>Some people may not realise many landlines don’t work in a power outage, and of course, mobile phones can’t be recharged. Ensure the person with dementia has access to an <a href="https://www.telstra.com.au/support/category/home-phone/uninterruptible-power-supply">uninterruptable power supply</a>. This can help maintain communication for a few hours in a blackout.</p> <p><strong>4. Have an evacuation plan</strong></p> <p>In case of fire, flash flooding or severe storm, <a href="https://dementiaresearch.org.au/wp-content/uploads/2017/10/2447_DCRC_Prep_natural_disaster_EBook_5.pdf">have an evacuation plan</a>. If the person with dementia attends a day or respite centre, know their plan too.</p> <p>The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues.</p> <p>Understand that someone with dementia may become distressed when their routine is disrupted. So be prepared with some simple activities or comfort items, current medications, and any specific medical information.</p> <p>Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible.</p> <h2>We can all help</h2> <p>It’s not just carers of people with dementia who can help. We can all ensure people with dementia stay safe and cool this spring and summer.</p> <p>So remember to check in on your relatives, friends and neighbours or arrange for someone to do so on your behalf.<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/213987/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/nikki-anne-wilson-342631"><em>Nikki-Anne Wilson</em></a><em>, Postdoctoral Research Fellow, Neuroscience Research Australia (NeuRA), <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

<p>One of the world's most extreme restaurants has gone viral and not only for its unique location and shape, but also its exclusive dining experience that's eerily similar to 2022 horror film <em>The Menu</em>.</p> <p>Restaurant Iris is located inside a giant silvery orb in Hardangerfjord, the second largest Fjord in Norway.</p> <p>The four-storey structure, called the Salmon Eye is inspired by - you guessed it - the shape of a fish eye, and it is quite a sight to behold. </p> <p>The Salmon Eye is covered in 9,000 steel plates to emulate fish scales, weighing a whopping 1,256 tonnes and an impressive diameter of 25 metres, with one sub-surface floor that boasts a panoramic view of the Fjord. </p> <p>The restaurant itself can only be accessed by an electric boat off the shore of Rosendal, as guests are treated to "an exclusive expedition dining-journey" which offers an 18-course meal and panoramic views. </p> <p>The 24-seat restaurant is run by Head Chef Anika Madsen, and prior to having their main meal, guests are taken to the chef's boathouse on the nearby island of Snilstveitoy, for a "welcoming snack". </p> <p>The menu is designed to showcase "the most local ingredients possible", which reflects Madsen's "commitment to sustainability" and her "<span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;">passion for discovering new ingredients from the ocean". </span></p> <p>Mari Eriksmoen posted the viral video on TikTok which has racked up over eight million views. </p> <p>"This spectacular just opened in the middle of the Hardangerfjord in Norway," she started in the clip with a shot of the structure floating in the middle of the fjord. </p> <p>She described the experience of walking into the restaurant "like entering a spaceship," and was mesmerised by the "insane views". </p> <p>Once the evening kicks off, guests indulge in a multi-sensory experience where they were instructed to pick a "cracker" hanging from the ceiling after watching a "short movie about food waste". </p> <p>Another TikTok user compared it to the <span style="background-color: #ffffff; font-family: graphik, Arial, sans-serif; font-size: 16px; letter-spacing: -0.16px;">extraterrestrial spacecraft </span><span style="background-color: #ffffff; font-family: graphik, Arial, sans-serif; font-size: 16px; letter-spacing: -0.16px;">from the 2016 sci-fi film <em>Arrival</em>.</span></p> <p>However many other users compared the dining experience to 2022 horror film <em>The Menu</em>, where a group of guests eat at an exclusive restaurant on a remote island and face dire consequences. </p> <p>"Did we learn nothing from The Menu?" commented one user with the crying face emoji. </p> <p>"I know how this movie ends," wrote another user. </p> <p>"I can’t a fjord it," joked a third. </p> <p>The dining experience aims to "blend gastronomy and activism on a global scale" as they hope to raise awareness on the the challenges and threats to the global food system. </p> <p>"The menu at Iris reads like a story, " a statement said. </p> <p>"A story about the challenges and threats to the global food system, but also with ideas and suggestions for future innovations, that can help bring us closer to solving them." </p> <p>The tasting menu itself is priced at 3,200 Norwegian Krone ($316) with an optional wine pairing for 2,500 Norwegian Krone ($247). </p> <p>For those who want to visit the Salmon Eye, but don't want to dine in, they can buy a ticket for a  two-hour "learning experience" at the centre priced at 349 Norwegian Krone ($34). </p> <p><em>Images: Salmon Eye Website/ Instagram, TikTok</em></p> <p> </p>

Extreme weather events are exactly the time to talk about climate change – here’s why

<p><em><a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a></em></p> <p>Record-breaking heatwaves are <a href="https://public.wmo.int/en/media/news/simultaneous-heatwaves-hit-northern-hemisphere-summer-of-extremes">sweeping across the northern hemisphere</a>, affecting large parts of southern Europe, the US and China. On July 24, Sicily recorded blistering temperatures <a href="https://www.bbc.com/news/world-europe-66302472">of more than 47.5℃</a> and wildfires are currently <a href="https://www.theguardian.com/world/2023/jul/25/how-bad-are-wildfires-in-greece-what-caused-them-visual-guide-heatwave">tearing through Greece</a>. The heatwaves come as <a href="https://www.reuters.com/graphics/CANADA-WILDFIRE/HISTORIC/znvnzebmavl/">record numbers of fires continue to burn</a> across Canada.</p> <p>A <a href="https://www.bbc.co.uk/news/science-environment-66289489">study by the World Weather Attribution group</a> found that these heatwaves would have been “virtually impossible” without climate change. In fact, the heatwave that is affecting parts of China was made 50 times more likely by global warming. This is exactly what climate scientists have been warning us about for decades – climate change makes many types of extreme weather event <a href="https://www.carbonbrief.org/explainer-what-the-new-ipcc-report-says-about-extreme-weather-and-climate-change/">more likely, more intense and longer lasting</a>.</p> <p>As a PhD researcher examining extreme weather events and climate change communication, I have spent the past four years exploring how extreme weather events may affect the way the public feels, thinks and acts on climate change.</p> <p>One area of interest to researchers is how extreme weather events might reduce the <a href="https://www.sciencedirect.com/science/article/pii/S0272494422000676">“psychological distance”</a> associated with climate change. While climate change can feel abstract and vague, extreme weather is something people can experience firsthand.</p> <p>But <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab466a/meta">research offers contrasting results</a>. Some studies have found that extreme weather events lead to an <a href="https://www.journals.uchicago.edu/doi/full/10.1017/S0022381612000448?casa_token=dTns6Kvds1AAAAAA%3AkQcleVJ95vJUyh5Pg2vxvFEDbzfR1RsuOI131QCMO0wvdtIiLSVEq4EW6fZYwC7Yhraxj-NB9g">increased belief</a> that human-driven climate change is occurring and <a href="https://link.springer.com/article/10.1007/s10584-016-1837-4">greater support for climate action</a>. Others <a href="https://link.springer.com/article/10.1007/s10584-021-03176-z">find no effects</a> or suggest that these effects are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959378017309135?via%3Dihub">only temporary</a>.</p> <p>However, <a href="https://www.nature.com/articles/s41467-022-32412-y">we often underestimate</a> how much the public already cares about climate change. In Britain, <a href="https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1164127/desnz-pat-spring-2023-net-zero-and-climate-change.pdf">just 4% of the public</a> say they are not at all concerned about climate change, while only <a href="https://climatecommunication.yale.edu/about/projects/global-warmings-six-americas/">11% of Americans</a> dismiss the issue.</p> <p>Given that <a href="https://www.pewresearch.org/short-reads/2019/04/18/a-look-at-how-people-around-the-world-view-climate-change/">most people</a> are already concerned about climate change, an important question now is how to shift these existing concerns into action.</p> <p><a href="https://theconversation.com/how-to-talk-to-your-family-and-friends-about-the-new-ipcc-report-five-tips-from-climate-change-communication-research-202306">Talking about climate change</a> is a powerful way of mobilising climate action, and extreme weather events provide helpful climate conversation starters. We can use these moments as opportunities to <a href="https://journals.sagepub.com/doi/10.1177/20563051231177930">engage our families, friends and communities</a> in discussions about how climate change may relate to these events and <a href="https://drawdown.org/solutions">what we can do about it</a>.</p> <p>So, if you decide to engage people you know in discussions about extreme weather and climate change, here are a few thoughts and guidelines to keep in mind.</p> <h2>1. Listen and share perspectives</h2> <p><a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618520300773">Extreme weather events can be traumatic</a> and climate change can evoke a wide range of emotional responses. If the person you are talking to is comfortable discussing the topic, ask them about their experiences and observations.</p> <p>Encourage them to tell stories and affirm the validity of their emotional response – whether they are afraid, angry, hopeful or worried. There is no one right way to feel about climate change, so listen to what they have to say and then share your own perspective too.</p> <h2>2. Talk about planning and preparation</h2> <p>When discussing extreme weather events, some people may link their experiences to climate change, while others focus on various local factors that contribute to extreme weather risks.</p> <p>The risks associated with extreme weather arise from a <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/summary-for-policymakers/">combination</a> of factors. These include the weather itself, which can be influenced by climate change, the level of exposure of people and places to extreme weather and the vulnerability of those to harm.</p> <p>Climate change, for instance, can affect the frequency, intensity and duration of wildfires. But emergency responses, evacuation procedures, firefighting and healthcare systems are crucially important to reduce risks. There are also significant equity and justice implications of extreme weather as different populations are <a href="https://link.springer.com/article/10.1007/s41885-020-00060-5">affected disproportionally</a>.</p> <p>It’s also important to bear in mind that while climate change affects many extreme weather events, it <a href="https://www.carbonbrief.org/climate-change-not-the-main-driver-of-madagascar-food-crisis-scientists-find/">does not necessarily affect every instance</a>. Weather systems are complex and there are <a href="https://theconversation.com/heres-why-climate-change-isnt-always-to-blame-for-extreme-rainfall-206958">meteorological processes</a> that scientists are still trying to understand.</p> <p>We also need to make sure the roles of local planning and preparation in minimising the impact of these events are not overlooked.</p> <h2>3. Challenge arguments about politicising the weather</h2> <p>In May 2023, Republican governor of Florida, Ron DeSantis, dismissed concerns about global warming by claiming that he rejects the <a href="https://www.independent.co.uk/news/world/americas/us-politics/desantis-climate-change-fox-news-b2346211.html">“politicisation of the weather”</a>. Ontario premier, Doug Ford, recently <a href="https://www.cbc.ca/news/canada/toronto/ontario-climate-change-forest-fires-politics-ford-stiles-1.6869071">made a similar argument</a> about Canada’s wildfires.</p> <p>In conversations, it’s possible that someone might accuse you too of “politicising” the weather. You can (respectfully) push back against this claim.</p> <p>This argument is a <a href="https://www.cambridge.org/core/journals/global-sustainability/article/discourses-of-climate-delay/7B11B722E3E3454BB6212378E32985A7">discourse of climate delay</a>. Rather than denying the existence of human-driven climate change, climate delay discourses try to shut down climate discussions and cast doubt on the need to act very quickly. These arguments disingenuously assert that acting on climate is too expensive, too late or that someone else should take care of it – and they are <a href="https://theconversation.com/climate-change-multi-country-media-analysis-shows-scepticism-of-the-basic-science-is-dying-out-198303">becoming increasingly common</a>.</p> <p>If we shouldn’t discuss climate change when extreme weather occurs, then when is the right time? If we want to protect lives, we need to talk about – and act upon – the risks associated with extreme weather events and the disasters they can cause.</p> <p>If talking about climate change politicises the weather, so be it. The politics of climate denial and delay affected this summer’s weather, and our current decisions will shape our planet for thousands of years.</p> <p>The science is clear. Act now or face increasingly dire consequences.<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/210412/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/josh-ettinger-1302389">Josh Ettinger</a>, Doctoral researcher, School of Geography and the Environment, <a href="https://theconversation.com/institutions/university-of-oxford-1260">University of Oxford</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Extreme Hollywood body transformations have become standard preparations for film actors – but we need to consider the consequences

<p><em><a href="https://theconversation.com/profiles/gemma-sharp-314703">Gemma Sharp</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/bronwyn-dwyer-1453560">Bronwyn Dwyer</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>“…when you’re shooting a film like Magic Mike, and you’re doing dance routines for two weeks at a time, you have to peak every day. So that became kind of crazy. We had a gym in the parking lot, and we’d all be lifting weights on set all day,” <a href="https://wegotthiscovered.com/movies/interview-channing-tatum-joe-manganiello-magic-mike/">explained actor Joe Manganiello</a>, about performing in the film Magic Mike.</p> <p>It is not unusual for actors to undergo drastic changes in preparation for a role, including gaining muscle and losing body fat for that shredded look. In fact, this is becoming the norm in Hollywood.</p> <p><a href="https://www.menshealth.com/fitness/a43945188/jake-gyllenhaals-road-house-transformation/">Jake Gyllenhaal</a> in Road House, <a href="https://www.insider.com/michelle-rodriguez-rege-jean-page-workout-dungeons-and-dragons-sdcc-2022-7">Michelle Rodriguez</a> in Dungeons &amp; Dragons, and <a href="https://www.menshealth.com/entertainment/a42532547/paul-rudd-marvel-ant-man-interview/">Paul Rudd</a> in Ant-Man and the Wasp: Quantumania, have all undertaken body modifications for roles this year.</p> <p>As the audience, we readily accept these body modifications to be part of the preparation for the role without necessarily considering the potentially long-term physical and mental health consequences.</p> <h2>So how do they do it?</h2> <p>From what Hollywood shares with the general public about these body modifications, which is generally very limited, it appears these transformations occur through excessive exercise and highly restrictive diets.</p> <p>Nevertheless, these Hollywood workouts are highly popular with ordinary people, with Dwayne “The Rock” Johnson and Chris Hemsworth’s workouts <a href="https://sustainhealth.fit/lifestyle/most-searched-hollywood-actor-workouts/">particularly sought after</a>.</p> <p>These regimens resemble those of competitive bodybuilders, <a href="https://journals.lww.com/hrpjournal/Abstract/2019/07000/Competitive_Bodybuilding__Fitness,_Pathology,_or.3.aspx">whose success also relies on appearance</a>.</p> <p>The <a href="https://link.springer.com/article/10.2165/00007256-200434050-00004">typical process for bodybuilders</a> involves two phases: a “bulking” phase, during which the goal is to have enough energy for muscle growth, and a “cutting” phase, when the aim is to lose weight but not muscle.</p> <p>The end result of such a process is usually highly applauded, even though drastic measures have been taken to achieve such a look.</p> <p>Actors of all genders are undergoing these body transformations for <a href="https://www.sportskeeda.com/comics/10-marvel-actors-whose-body-transformation-shocked-world">various roles</a> such as superheroes, athletes, or the portrayal of real-life people.</p> <h2>What are the consequences?</h2> <p>“I’ve become a little bit more boring now, because I’m older and I feel like if I keep doing what I’ve done in the past I’m going to die. So, I’d prefer not to die,” <a href="https://www.menshealth.com/uk/fitness/lifestyle/a29725245/christian-bale-no-more-body-transformation-roles/">said Christian Bale</a>, who has undertaken multiple extreme transformations for roles.</p> <p>To achieve what is needed for a particular role, extreme measures are often taken. However, the consequences of these measures, such as use of substances, exercise dependence, and an increased risk of developing muscle dysmorphia and/or an eating disorder, is seemingly not common knowledge.</p> <p>A concern for the bodybuilding community is the widespread use of drugs, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4026349/">often multiple drugs at a time not obtained through prescription</a>. Androgenic-anabolic steroids are commonly used which can have extensive negative effects on the human body, including on the cardiovascular system, hormones, metabolism and even psychiatric wellbeing.</p> <p>Exercise dependence can also occur when an individual engages in an extreme amount of exercise, to the point at which <a href="https://link.springer.com/article/10.1007/s11936-018-0674-3">physical, psychological or emotional harm</a> can occur. We are not sure exactly why exercise dependence happens, but it could potentially be a form of <a href="https://www.tandfonline.com/doi/full/10.1080/19585969.2023.2164841">behavioural addiction</a>.</p> <p>Another risk is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4977020/">muscle dysmorphia</a>, a subtype of body dysmorphic disorder characterised by the individual being preoccupied with the idea their physique is not muscular enough, even if they have a high degree of muscle.</p> <h2>What about the dieting impacts?</h2> <p>There are many similarities between the requirements of bodybuilding and eating disorders. Both are characterised by restrictive diets, high levels of exercise, potential social isolation, and adherence to a <a href="https://journals.lww.com/hrpjournal/Abstract/2019/07000/Competitive_Bodybuilding__Fitness,_Pathology,_or.3.aspx">rigid schedule</a>.</p> <p>The seminal <a href="https://www.sciencedirect.com/science/article/pii/S002231662210249X?via%3Dihub">Minnesota Starvation Experiment</a> fundamentally shaped our understanding of the changes a person can experience when they are consuming less than their daily nutrition energy needs, such as during the “cutting” phase for bodybuilders. This research showed that people who are experiencing starvation for a period of time will experience devastating impacts in the physical, psychological, behavioural and social aspects of their lives.</p> <p>Some of the many documented changes included reductions in heart muscle mass, heart rate and blood pressure, dizziness, fatigue, increased feelings of depression and anxiety, obsessive thoughts about food, and withdrawal from social activities and relationships.</p> <p>Concerningly, even once a person is renourished, the psychological issues around body size and food <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/eat.23095">can persist</a>. Therefore, even after an actor has returned to their pre-modification weight and size, it does not mean they have recovered from the consequences that came with that body modification.</p> <h2>What are the impacts on the general public?</h2> <p>Rapid changes in physical appearance are not realistically achievable for most people. So seeing actors doing this seemingly easily with the assistance of their professional teams sets an <a href="https://link.springer.com/article/10.1007/s40894-022-00179-4">unrealistic standard</a>.</p> <p>For people without the same income or access to resources to achieve these body modifications in a safe way, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8872588/">more extreme means</a> would be undertaken and consequent damage to mental and physical wellbeing can ensue. These body modifications are definitely a case of “do not try this at home”.</p> <p>There are many risks when undertaking dramatic body modifications, most of which are not talked about in public. Actors are just as vulnerable to these risks, despite us rarely seeing what exactly they go through to achieve these dramatic transformations. Hollywood is a highly competitive environment, and being honest about body modification and its consequences could stop an actor landing their next gig.</p> <p>We don’t recommend body modifications in any way, but if someone does want to make a change to their lifestyle, we strongly recommend consulting with a team of health professionals to ensure physical and psychological safety during the process and beyond.</p> <p>––</p> <p><em>If this article has raised issues for you, or if you’re concerned about someone you know, do not hesitate to reach out for support.

For example, after decades of mass mountaineering, the environmental <a href="https://theconversation.com/70-years-after-the-first-ascent-of-everest-the-impact-of-mass-mountaineering-must-be-confronted-204270">impact</a> on Mount Everest must be addressed.</p> <p>And when mishaps do occur, the cost of search and rescue efforts can be massive and put rescue teams at great risk.

Marketing materials aim to sell “safe” adventures, with the risks are often listed in the fineprint. A <a href="https://www.tandfonline.com/doi/full/10.1080/11745398.2017.1286512">polar plunge</a> in Antarctica, for instance, is often marketed as safe because participants are attached to a tether and the swim time is limited to prevent hypothermia.</p> <p>Two decades ago, in forecasting the growth of space tourism, anthropologist Valene Smith <a href="https://www.tandfonline.com/doi/pdf/10.1080/02508281.2000.11014920">said</a> what tourists want, the industry will provide. This has become a truism, as the Titan voyages demonstrate.</p> <p>The massive growth of frontier tourism could lead to even greater problems if the industry doesn’t respond in the right way. If travellers are going to expose themselves to extreme risks, whose responsibility is it, then, to ensure their safety and recovery should accidents occur?</p> <p>Many tourism businesses and travel insurance companies make risks known to their guests. But regulations on disclosing risks differ between countries. These means travellers may have to evaluate the risks themselves, and this is fraught with danger if company standards are low.</p> <p>One solution is frontier tourism might be best experienced in controlled and safe environments through <a href="https://www.tandfonline.com/doi/full/10.1080/14616688.2023.2224043">digital storytelling</a> or <a href="https://www.mdpi.com/2071-1050/15/4/3348">augmented and mixed reality</a>. However, this may not be enough to satisfy the adrenaline junkies out there.</p> <p>As the Titan incident illustrates, the unpredictable nature and unintended consequences of frontier tourism are very real things. While money can allow us to travel almost anywhere, it’s worth considering whether some places should just remain untouched, sacred and off limits completely.<!-- Below is The Conversation's page counter tag.

Floods, cyclones, thunderstorms: is climate change to blame for New Zealand’s summer of extreme weather?

<p>The final months of New Zealand’s summer carried a massive sting, bringing “unprecedented” rainfalls several times over, from widespread flooding in Auckland at the end of January to ex-tropical Cyclone Gabrielle dumping record rains and causing devastating floods across the east coast of the North Island.</p> <p>After all that, New Zealand experienced spells of thunderstorms, bringing repeat floods to parts of Auckland and then Gisborne.</p> <p>The obvious question is what role climate change plays in these record-breaking rainfalls.</p> <p>Some answers come from the international <a href="https://www.worldweatherattribution.org/">World Weather Attribution</a> team, which today released a <a href="https://spiral.imperial.ac.uk/bitstream/10044/1/102624/10/Scientific%20report%20New%20Zealand%20Floods.pdf">rapid assessment</a> which shows very heavy rain, like that associated with Cyclone Gabrielle, has become about four times more common in the region and extreme downpours now drop 30% more rain.</p> <p>The team analysed weather data from several stations, which show the observed increase in heavy rain. It then used computer models to compare the climate as it is today, after about 1.2℃ of global warming since the late 1800s, with the climate of the past.</p> <p>The small size of the analysed region meant the team could not quantify the extent to which human-caused warming is responsible for the observed increase in heavy rain in this part of New Zealand, but concluded it was the likely cause.</p> <h2>More energy in the atmosphere and ocean</h2> <p>Many factors add to the strength of a storm and the intensity of rainfall, especially for short bursts. A crucial factor is always the amount of energy available.</p> <p>Climate change is increasing that amount of energy in two main ways. First, everything is getting warmer. Rising sea surface temperatures provide <a href="https://sciencebrief.org/uploads/reviews/ScienceBrief_Review_CYCLONES_Mar2021.pdf">extra fuel for the development of tropical cyclones</a> because they grow by heating from below.</p> <p>Warmer seas mean potentially faster development of tropical cyclones, and stronger, more vigorous storms overall. Sea temperatures must be at least 26.5℃ to support the build-up of a tropical cyclone. So, as the oceans warm, these storms can reach farther from the equator.</p> <p>Second, warmer air can hold more water vapour. Every degree of warming increases the maximum amount of water vapour by around 7%. That extra water vapour tends to fall out as extra rain, but it also provides extra energy to a storm.</p> <h2>Driving waves further inland</h2> <p>The energy it takes to evaporate the water from the ocean surface and turn it into vapour is released again when the vapour condenses back into liquid water. A moister airmass heats the atmosphere more when clouds and rain form, making the air more buoyant and able to rise up more. This creates deeper, more vigorous clouds with stronger updrafts, and again more rain.</p> <p>Stronger updrafts in a storm mean more air will have to be drawn into the storm near the Earth’s surface, ensuring more “convergence” of air and moisture (water vapour). That’s why, even though a degree of warming translates to 7% more water vapour in the air, we can get 20% increases, or larger, in extreme rainfalls.</p> <p>All of this extra energy can contribute to making the storm stronger overall, with stronger winds and lower air pressures in its centre. This seems to have happened with Cyclone Gabrielle. Record low pressures were recorded at a few North Island locations as the storm passed.</p> <p>The low pressures act like a vacuum cleaner, sucking the sea surface up above normal sea level. The strong winds can then drive waves much further inland. Add in a bit of sea-level rise, and coastal inundation can get a lot worse a lot quicker.</p> <p>As the climate continues to change, storm intensity is likely to increase on average, as sea levels continue to rise. Those effects together are bound to lead to more dramatic coastal erosion and inundation.</p> <h2>Thunderstorms riding warming seas</h2> <p>These processes work for thunderstorms as well. A thunder cloud often starts as a buoyant mass of air over a warm surface. As the air rises (or convects), it cools and forces water vapour to condense back to liquid water, releasing heat and increasing the buoyancy and speed of the rising air.</p> <p>Again, that allows more moist air to be drawn into the cloud, and that convergence of moist air can increase rainfall amounts well above the 7% per degree of warming, for short bursts of very intense convection. The more intense the convection, the stronger the convergence of moisture and the heavier the resulting rainfall.</p> <p>Tropical cyclones have rings of thunderstorms around their eye during the time when they are truly tropical storms. As they transition out of the tropics into our neighbourhood, they change their structure but retain a lot of the moisture and buoyancy of the air. An ex-tropical cyclone like Gabrielle, moving over very warm water, can pack a devastating punch.</p> <p>Why has New Zealand had so much of this very heavy rain during the weeks from late January? Partly it’s the very warm ocean waters around Aotearoa (up to marine heatwave conditions) and farther north into the Coral Sea. That itself is partly related to the ongoing La Niña event in the tropical Pacific, which tends to pile up warm water (and tropical cyclones) in the west.</p> <p>But it is also related to ongoing global warming. As sea temperatures increase, it becomes easier to reach heatwave conditions. Warmer seas load the atmosphere with water vapour.</p> <p>Partly, too, the air over the North Island has been unusually “unstable” lately, very warm near ground level but cooler than normal higher up. That makes the buoyance in thunderstorms work even better and more strongly, encouraging very heavy rainfall.</p> <p>These conditions seem to have eased now, but severe thunderstorms continue to develop. As we move from summer into autumn, as the warmest seas move eastwards away from us and as La Niña fades in the tropics, the chances of a repeat event are diminishing. For now at least.</p> <p>But if we continue to warm the climate with more greenhouse gas emissions, we will continue to load the dice towards more very heavy rain over Aotearoa. Let us hope those regions and communities so badly affected by recent events have a chance to dry out, rebuild and recover before the next extreme weather.</p> <p><em>This article originally appeared on <a href="https://theconversation.com/floods-cyclones-thunderstorms-is-climate-change-to-blame-for-new-zealands-summer-of-extreme-weather-201161" target="_blank" rel="noopener">The Conversation</a>.</em></p> <p><em>Images: Getty</em></p>

Can ideology-detecting algorithms catch online extremism before it takes hold?

<p>Ideology has always been a critical element in understanding how we view the world, form opinions and make political decisions. </p> <p>However, the internet has revolutionised the way opinions and ideologies spread, leading to new forms of online radicalisation. Far-right ideologies, which advocate for ultra-nationalism, racism and opposition to immigration and multiculturalism, have proliferated on social platforms.</p> <p>These ideologies have strong links with violence and terrorism. In recent years, <a href="https://www.asio.gov.au/sites/default/files/2022-02/ASIO_Annual_Report_2020-21.pdf">as much as 40%</a> of the caseload of the Australian Security Intelligence Organisation (ASIO) was related to far-right extremism. This has <a href="https://www.abc.net.au/news/2023-02-13/right-wing-terror-threat-declines-says-asio/101965964">declined</a>, though, with the easing of COVID restrictions.</p> <p>Detecting online radicalisation early could help prevent far-right ideology-motivated (and potentially violent) activity. To this end, we have developed a <a href="https://arxiv.org/abs/2208.04097">completely automatic system</a> that can determine the ideology of social media users based on what they do online.</p> <h2>How it works</h2> <p>Our proposed pipeline is based on detecting the signals of ideology from people’s online behaviour. </p> <p>There is no way to directly observe a person’s ideology. However, researchers can observe “ideological proxies” such as the use of political hashtags, retweeting politicians and following political parties.</p> <p>But using ideological proxies requires a lot of work: you need experts to understand and label the relationships between proxies and ideology. This can be expensive and time-consuming. </p> <p>What’s more, online behaviour and contexts change between countries and social platforms. They also shift rapidly over time. This means even more work to keep your ideological proxies up to date and relevant.</p> <h2>You are what you post</h2> <p>Our pipeline simplifies this process and makes it automatic. It has two main components: a “media proxy”, which determines ideology via links to media, and an “inference architecture”, which helps us determine the ideology of people who don’t post links to media.</p> <p>The media proxy measures the ideological leaning of an account by tracking which media sites it posts links to. Posting links to Fox News would indicate someone is more likely to lean right, for example, while linking to the Guardian indicates a leftward tendency. </p> <p>To categorise the media sites users link to, we took the left-right ratings for a wide range of news sites from two datasets (though many are available). One was <a href="https://reutersinstitute.politics.ox.ac.uk/our-research/digital-news-report-2018">based on a Reuters survey</a> and the other curated by experts at <a href="https://www.allsides.com/media-bias/ratings">Allsides.com</a>. </p> <p>This works well for people who post links to media sites. However, most people don’t do that very often. So what do we do about them?</p> <p>That’s where the inference architecture comes in. In our pipeline, we determine how ideologically similar people are to one another with three measures: the kind of language they use, the hashtags they use, and the other users whose content they reshare.</p> <p>Measuring similarity in hashtags and resharing is relatively straightforward, but such signals are not always available. Language use is the key: it is always present, and a known indicator of people’s latent psychological states. </p> <p>Using machine-learning techniques we found that people with different ideologies use different kinds of language. </p> <p>Right-leaning individuals tend to use moral language relating to vice (for example, harm, cheating, betrayal, subversion and degradation), as opposed to virtue (care, fairness, loyalty, authority and sanctity), more than left-leaning individuals. Far-right individuals use grievance language (involving violence, hate and paranoia) significantly more than moderates. </p> <p>By detecting these signals of ideology, our pipeline can identify and understand the psychological and social characteristics of extreme individuals and communities.</p> <h2>What’s next?</h2> <p>The ideology detection pipeline could be a crucial tool for understanding the spread of far-right ideologies and preventing violence and terrorism. By detecting signals of ideology from user behaviour online, the pipeline serves as an early warning systems for extreme ideology-motivated activity. It can provide law enforcement with methods to flag users for investigation and intervene before radicalisation takes hold.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/can-ideology-detecting-algorithms-catch-online-extremism-before-it-takes-hold-200629" target="_blank" rel="noopener">The Conversation</a>. </em></p>

‘One of the most extreme disasters in colonial Australian history’

<p>The deluge dumped on southeast Queensland and northern New South Wales this week has been catastrophic. Floodwaters peaked at around 14.4 metres high in Lismore – two metres higher than the city’s previous record.</p> <p>So how does this compare to Australia’s previous floods, such as in 2011? And can we expect more frequent floods at this scale under climate change? The answers to questions like these aren’t straightforward.</p> <p>Climate change doesn’t tell the whole story, as extreme rainfall can occur for a <a href="https://theconversation.com/like-rivers-in-the-sky-the-weather-system-bringing-floods-to-queensland-will-become-more-likely-under-climate-change-176711">variety of reasons</a>. What’s more, it’s too soon to officially state whether this event is directly linked to climate change, as this would require a formal event attribution study. This can take months or years to produce.</p> <p>In any case, we do know extreme events like this will occur more frequently in a warmer world.

But, there’s very high variability in rainfall for this region, and La Niña – a natural climate phenonenon associated with wetter weather – often brings flooding to this area, as we saw in 2010/2011 and in the 1970s.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.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/449171/original/file-20220301-15-1h65whn.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/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=424&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=424&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=424&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=533&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=533&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=533&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Trends in maximum 3-day rainfall in summer (December-February) from 1959/1960 to 2019/2020 show mixed trends in the flood-affected region.

However, we also need the right weather systems in place to trigger the release of moisture from the air and cause extreme rainfall. The climate change effect on these systems is uncertain.</p> <p><strong>Climate change and weather systems</strong></p> <p>The severity of the flooding in southeast Queensland is partly due to a weather system called an “<a href="https://theconversation.com/like-rivers-in-the-sky-the-weather-system-bringing-floods-to-queensland-will-become-more-likely-under-climate-change-176711">atmospheric river</a>” sitting over the region for days. To make matters worse, the rain fell on an already sodden ground due to both the higher-than-average rainfall from the current La Niña, and the La Niña in the 2020-2021 summer. This made a huge difference to the scale of the floods.</p> <p>We don’t fully understand how the persistence of these natural systems will change in future, but recent work shows climate change will cause long-lasting atmospheric rivers over Sydney to occur <a href="https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2021GL095335">almost twice as often</a> by the end of the 21st century.

Extreme heat increases health risk for everyone

<div class="copy"> <p>Extreme heat is a <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/understanding-killer-heat/" target="_blank">killer</a>. It’s responsible for thousands of deaths around the world every year, with a huge proportion of those already <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/climate-change-causes-one-third-of-heat-related-deaths/" target="_blank">attributed to rising global temperatures</a>.</p> <p>Studies have long shown that people over the age of 65 face an increased risk of hospital admission and death during extreme heat days, but US and Canadian researchers have now found that young and middle-aged people are at risk, too.</p> <p>“By looking at emergency department visits for different causes and for several age groups, we were able to characterise with accuracy the varying impact on health on different populations,” says study co-author Francesca Dominici, from the Harvard T.H. Chan School of Public Health.</p> <p>“An important goal of this study is to provide actionable information to clinicians and public health experts regarding how to prevent these emergency department visits, also considering that we can anticipate when these extreme heat events are likely to occur.”</p> <p>Published in the <em>BMJ,</em> <a rel="noreferrer noopener" href="https://dx.doi.org/10.1136/BMJ-2021-065653" target="_blank">the study</a> found that extremely hot days – with an average temperature of 34.4°C – are associated with a higher risk of emergency department (ED) presentation for adults of all ages.</p> <p>The strongest association was for adults between the ages of 18 and 64.</p> <p>The study was large, spanning more than 74 million adults and 22 million ED visits across 2939 US counties during the months of May to September from 2010 to 2019. It used medical insurance claims data to investigate links between hot days and rates of ED visits for any cause as well as specific causes (namely heat-related illness, kidney disease, cardiovascular disease, respiratory disease and mental disorders).</p> <p>Extreme heat days increased people’s risk of an ED visit by 66% for a heat-related illness, as well as by 30% for renal disease.</p> <p>But the risk varied with age – there was a 10.3% higher risk of ED visits in people ages 45 to 54 years old, compared to a 3.6% higher risk in those older than 75.</p> <p>“Younger adults may be at greater risk of exposure to extreme heat, particularly among workers that spend substantial time outdoors,” says lead author Shengzhi Sun, from the Department of Environmental Health at Boston University School of Public Health (BUSPH). “Younger adults may also not realise that they too can be at risk on days of extreme heat.”</p> <p>Gregory Wellenius, professor of environmental health at BUSPH, says the researchers chose to look at ED visits instead of hospital admissions for a reason.</p> <p>“Many illnesses that lead to utilisation of the emergency department do not lead to hospitalisation because they can be treated in a short amount of time, particularly among the younger adult population,” he explains.</p> <p>“By looking at emergency room visits, we aimed to obtain a more comprehensive picture of the true burden of disease that might be attributed to the days of high heat.”</p> <p>The study also found differences in risk across regions – there was a higher risk of ED visits on extreme heat days in the US’s northwest, midwest and northwest, as opposed to the hotter southeast. The researchers say this shows heat is especially dangerous in cooler climates, where people may be less adapted to, or less aware of, heat.</p> <p>This is crucial to recognise as global temperatures rise, particularly as countries, states and regions are deciding how to adapt.</p> <p>“Although climate change is a global problem and heat threatens the health of everybody across the world, the impacts are felt locally, and the solutions have to be tailored to local needs,” says Wellenius.</p> <p>“What works for heatwave preparedness in the Pacific Northwest is really different from what works in the southeastern US, so the solutions have to be localised to accommodate the needs of the local community.” Extreme heat is a particular problem in cities. Exposure to deadly urban heat has <a rel="noreferrer noopener" href="https://cosmosmagazine.com/earth/climate/scorching-cities-deadly-urban-heat-has-tripled/" target="_blank">tripled</a> since the 1980s, and with more than 50% of the world’s population currently living in urban areas, this signals an urgent need to <a rel="noreferrer noopener" href="https://cosmosmagazine.com/cosmos-briefing/cities-of-the-future/" target="_blank">redesign our future cities</a> to keep us healthy as the world warms.</p> <em>Image credits: Getty Images </em></div> <div id="contributors"> <p><em>This article was originally published on <a rel="noopener" href="https://cosmosmagazine.com/health/body-and-mind/study-lays-bare-the-health-risks-of-extreme-heat/" target="_blank">cosmosmagazine.com</a> and was written by Lauren Fuge. </em></p> </div>

<p>Lauren Rigby, a 22-year-old training to be a vet nurse, was one of many lives dramatically changed by the coronavirus pandemic.</p> <p>But not in the same way as everyone else.</p> <p>After a seemingly innocent trip to her local shops, Lauren's life was thrown into disarray as she noticed a rash forming on her hands.</p> <p>"They were saying please use hand sanitiser so I just put a little bit on and it started burning," she said.</p> <p>"I asked mum 'are your hands burning'? she said, 'no'."</p> <p>In the following weeks, Lauren developed severe eczema, which was impacting her everyday life.</p> <p><span>"I started noticing at the shops they were spraying disinfectant, even on the clothes, and then I noticed my body was covered in a rash after trying on clothes," she said.</span></p> <p><span>Her fragile skin started to peel off and her hair began to fall out, as her body had an extreme reaction. </span></p> <p><span><img style="width: 500px; height: 281.25px;" src="https://oversixtydev.blob.core.windows.net/media/7844688/lauren-rigby.jpg" alt="" data-udi="umb://media/a235e027209e4af2b2496e47870439ba" /></span></p> <p><em>Image credits: Channel 9 - A Current Affair</em></p> <p>"I was so swollen that it if you touched my arm it would leave a dent and my skin peeled off into piles that we had to vacuum up," Ms Rigby said.</p> <p>Lauren was hospitalised after her eczema triggered a genetic condition called Erythroderma, all caused by hand sanitiser.</p> <p>More than 12 months on, Lauren has a strict skincare regiment that is helping to slowly bring her eczema under control.</p> <p>"How can something so tiny change my life," she said.</p> <p>"I've never used hand sanitiser this year and I'll never use it again."</p> <p>Melanie Funk from Eczema Support Australia said there had been an increase of people seeking help during the COVID-19 period.</p> <p>"Certainly hand eczemas and facial eczemas are increasing with the pandemic measures," she said.</p> <p><span>"You shouldn't suffer in silence, there are others that understand, get support, get help, get treatment."</span></p> <p><em>Image credits: Channel 9 - A Current Affair</em></p>

Heartbroken son speaks out after Ruby Princess cruise ship death: “We’re just extremely mad”

<p>The Ruby Princess cruise ship quickly became a coronavirus hotspot with deadly consequences after eleven passengers passed away.</p> <p>Tasmanian man, 81-year-old Leonard Fisher was one of the victims who lost his life to the virus after boarding the cruise ship and his heartbroken son, Greg has spoken up about the horrific ordeal.</p> <p>Speaking to<u><em><span> </span>60 minutes,</em></u><span> </span>Greg said he wished he’d done more to convince his father out of leaving for his trip but his dad convinced him that if there had been anything wrong on the ship, Princess Cruises would have cancelled the cruise.</p> <p>"He said at my age, I'll probably never get a chance to do another trip like this again," Greg told Bartlett.</p> <p>However, as time went on Greg noticed his dad become increasingly more concerned throughout his trip.</p> <p>"He said that he had a gentleman sitting beside him that was coughing and coughing, and coughing, he had his hand over his mouth, and he was quite concerned about that," Greg told <em>60 Minutes</em>.</p> <p>"He did say that if he was aware that how bad this virus was, and if it was on the ship, he would never have got on the ship."</p> <p>Greg told Channel 9 both he and his dad had trusted the cruise line company as "At no stage were the passengers told that there was a possibility of coronavirus on that boat. They were unaware of any sickness that was on that boat, it was just so wrong,"</p> <p>Np passengers were told that in fact, 104 people on board were sick with respiratory infections and 15 had to be swabbed by the doctor onboard due to his fear of suspected COVID-19.</p> <p>Cruise passengers Gary and Kelly Callaghan expressed their frustrations that they were not warned that the disease had made its way on to the ship.</p> <p>"We are extremely mad, sad and cranky that we weren't told that somebody potentially had it on the ship. We're just extremely mad that we weren't told anything," she said.</p> <p>Neither Kelly or Gary were tested upon departure but instead were ushered quickly off the ship and were allowed to return into their communities and back to their homes.</p> <p>It is possible thousands were infected.</p> <p>"We were all expecting to be tested when we got off just to be sure, to be safe, you're letting us out in the public around people and nobody tested us and I really think that was disgraceful," Gary said.</p> <p>NSW Health deemed that the ship was a “low risk setting”, despite being told there were 15 passengers who had been swabbed for coronavirus.</p> <p>2700 passengers were disembarked without being tested.</p> <p>There are 600 cases of coronavirus linking back to the ruby cruise ship and 11 deaths.</p> <p>The Ruby Princess is now the largest single source of COVID-19 deaths in Australia.</p>

How to cope with extreme heat days without racking up the aircon bill

<p>Summer in Australia is <a href="http://www.bom.gov.au/climate/updates/articles/a032.shtml">getting hotter</a>. Extreme heat events, with daytime temperatures over 35 degrees Celsius, are becoming more common and we are getting more of these days in a row.</p> <p>We all need to prepare ourselves, our homes and our neighbourhoods for hot and very hot days. Since 2016, the <a href="https://www.westernsydney.edu.au/__data/assets/pdf_file/0020/1161470/cooling-the-commons-report.pdf">Cooling the Commons</a> research project has been working with people living in some of Sydney’s hottest neighbourhoods to learn how they cope with heat.</p> <p>Discussion groups with residents across hotspots in Western Sydney, including Penrith, Cranebrook and St Marys, highlighted a wealth of things we can do to manage heat. We published some of the following tips in a recent <a href="https://www.westernsydney.edu.au/ics/news/new_resource_by_institute_researchers_provides_advice_on_how_to_prepare_for_heat">flier</a>.</p> <p><strong>Why can’t we all just rely on air conditioning?</strong></p> <p>Official advice for extreme heat is often to stay inside and turn on the air conditioning. While air conditioning can play a role, <a href="https://www.canstarblue.com.au/appliances/air-conditioning-running-costs/">not everyone can afford it</a>. Low-income and older households can be especially vulnerable to bill shock and are more likely to feel the impacts of extreme heat.</p> <p>There is also the risk that running air conditioners uses <a href="https://www.theguardian.com/australia-news/2019/jul/09/australias-emissions-reach-the-highest-on-record-driven-by-electricity-sector">energy resources that contribute further to global warming</a>. More immediately, hot exhaust air from air-conditioning units can <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2013JD021225">make the local environment hotter</a>. This means keeping one home cool can make it harder for neighbours to keep their homes cool and make being outside even more uncomfortable.</p> <p>Air conditioning in private homes creates a cool refuge for only some. Unless those homes have an open-door policy on hot days, many of us will need to find other ways to keep cool. If you do have air conditioning, think about how you could share your air with those near you who might really need it.</p> <p><strong>Prepare before the heat hits</strong></p> <p><strong><em>Shade is important for creating more comfortable living spaces.</em></strong></p> <p>Identify which parts of your home get the most afternoon sun in summer. Can you plant trees or vines, or move a pot plant outside the window to create a green screen? Can you attach awnings to shade the windows?</p> <p>Low-cost temporary solutions can include attaching light-coloured shade cloth outside the window using removable hooks, or installing heavy drapes or blinds inside. Blankets or even aluminium foil are a low-cost creative way of keeping heat out.</p> <p><strong><em>Open up to let in cool air at night</em></strong></p> <p>Can you open the windows and doors overnight to let in cooler air? If you are concerned about security, look for options for locking the windows in an open position, or using flyscreens and security grilles on windows and doors.</p> <p>A low-cost option to keeping flying insects at bay on hot nights is a mosquito net over the window or around the bed.</p> <p><strong><em>Use low-cost resources to prepare in advance.</em></strong></p> <p>Ceiling or portable fans are one of the best ways to cool your body when it’s hot. But remember fans don’t cool rooms, so turn off the fan when you leave the room or you’re just burning electricity.</p> <p>Find ice trays and containers to freeze water – cake tins and storage containers are a good option. Putting these in front of a portable fan will mean the fan blows cool air.</p> <p>Putting a wet face cloth on the insides of your wrists, around your ankles or on the back of your neck will bring down your body temperature. Hanging damp sheets in doorways or in front of a fan will help keep the temperature down – although the trick with the sheets won’t work if it’s a really humid day.</p> <p><strong>How to stay cool and comfortable on hot days</strong></p> <p>Morning is likely to be the coolest time of the day. Open up your windows and doors to let in the cooler morning air.</p> <p>It’s the best time to be active – walk the dog, take the kids to the park, go for a swim. If possible, do your cleaning, cooking or outside work now. Plan meals that don’t require an oven.</p> <p><strong><em>Close up as it heats up.</em></strong></p> <p>As the day starts to get hot, close the house up – shut windows, blinds and curtains. This could be as early as 9am on really hot days. If you are heading out to work, do this before you leave home.</p> <p>Closing internal doors can help to keep the heat in one part of your home. You need to close doors to any parts of the home that get hot before the day gets hot.</p> <p><strong><em>Stay hydrated.</em></strong></p> <p>Drink plenty of water throughout the day. Put a jug of tap water in the fridge and remember to top it up.</p> <p>Don’t forget to move pet water bowls and day beds out of the sun. If you live in a dry area, it can’t hurt to put out extra water bowls for needy wildlife!</p> <p><strong><em>Find a cooling refuge.</em></strong></p> <p>If your home gets uncomfortably hot, find the closest cooling refuges in your neighbourhood. These are places where you can go to cool down. Good examples that won’t break the bank are the local swimming pool or library.</p> <p>Some local councils provide <a href="http://coolparramatta.com.au/">lists</a> of <a href="https://www.penrithcity.nsw.gov.au/waste-environment/cooling-the-city/beat-the-heat">cooling centres</a> on their websites.</p> <p><strong><em>Save air conditioning for when it’s most needed.</em></strong></p> <p>Try to save air conditioning for the hottest parts of the day. It will be most effective and cheapest to run if your home is well insulated and you’ve closed it up for the day.</p> <p><strong><em>Look after neighbours.</em></strong></p> <p>Remember to check on elderly or frail neighbours. Along with the very young, they are usually more affected by the heat and may need to cool down sooner than you do.</p> <p>If your neighbours are in need, consider inviting them into your home to cool down. When it’s hot, let’s <a href="https://www.semanticscholar.org/paper/Infrastructures-of-Care%3A-Opening-up-%E2%80%9CHome%E2%80%9D-as-in-a-Lopes-Healy/1920004e258483d40017ff468370e4892e11fce5">think of our cities as social commons</a> rather than a collection of private spaces.</p> <p><span><a href="https://theconversation.com/profiles/emma-power-250930"><em>Emma Power</em></a><em>, Senior Research Fellow, Geography and Urban Studies, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>; <a href="https://theconversation.com/profiles/abby-mellick-lopes-388977">Abby Mellick Lopes</a>, Associate Professor, Design, School of Humanities and Communication Arts, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>, and <a href="https://theconversation.com/profiles/louise-crabtree-128457">Louise Crabtree</a>, Associate Professor, Institute for Culture and Society, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></span></p> <p><em>This article is republished from <a href="http://theconversation.com">The Conversation</a> under a Creative Commons license.

Rome considers extreme measures to protect Trevi Fountain

<p>The Trevi Fountain is considered one of the must-see attractions in Rome, and many tourists flock there yearly to throw a coin into the fountain.</p> <p>Bad behaviour from tourists though may be responsible for a heavy-handed response from Rome’s city council to protect the iconic structure which could ruin the experience for others.</p> <p>In 2019, an American tourist was caught bathing in the fountain, another woman was stopped from carving the fountain with a key and three drunk Australians were caught pouring their drinks into the fountain.</p> <p>The fountain, which was built in 1762, is one of the most popular spots in Rome and is surrounded by tourists following the tradition of tossing three coins over their shoulders into the water.</p> <p>One politician has an idea on how to protect the icon: barriers.</p> <p>"Rome is one of the richest cities for culture in the world, and a heritage like this must be respected and protected," Andrea Coia, president of the business committee of Rome’s city council motion reads.</p> <p>"We need to favour a more respectful kind of tourism in the city's symbolic places."</p> <p>He has suggested that a “protective barrier” that would “prohibit people sitting on the edge of the fountain”.</p> <p>"I put forward the motion because the symbolic places of our city need more control and attention," Coia told<span> </span><em><a rel="noopener" href="https://edition.cnn.com/travel/article/trevi-fountain-barrier-overtourism/index.html" target="_blank">CNN Travel</a></em>, adding that his suggested Trevi Fountain checkpoints would be on the access roads "to safeguard decorum and security."</p> <p>He said that the measures would "safeguard one of the world's most beautiful places and assure a better experience for those who want to enjoy it."</p> <p>Scroll through the gallery to see why the barriers around the fountain might not be such a bad idea.</p>

“Extreme racism”: TV host’s appalling comments about Serena Williams

<p>A Romanian TV host has received heavy criticism after a shocking racial slur aimed at Serena Williams was made on air. </p> <p>Radu Branciu said on his evening show during the US Open he found Serena Williams to “look exactly like one of those monkeys at the zoo with the red asses”. </p> <p>“If monkeys wore trousers, they’d look exactly like Serena Williams does on the court,” he said.</p> <p>The National Council for Combating Discrimination in Bucharest has condemned Banciu’s comments.</p> <p>“The governing board shows that slavery of people of colour was based, among other things, on their comparison with monkeys,” a press release said.</p> <p>“As a result, such statements express a form of extreme racism.”</p> <p>Banciu was fined $2,700 however it doesn’t seem like the TV host will lose his job. </p> <p>This isn’t the first time Serena has faced racism at the hands of the media. </p> <p>The<span> </span><em>Herald Sun<span> </span></em>gained criticism in Australia and the U.S after the infamous US Open final in 2018 with a cartoon depiction of Serena which many labelled inappropriate and racist. </p> <blockquote class="twitter-tweet"> <p dir="ltr">Australia's media watchdog finds cartoon of <a href="https://twitter.com/hashtag/SerenaWilliams?src=hash&amp;ref_src=twsrc%5Etfw">#SerenaWilliams</a> did not breach standards. <a href="https://t.co/a6BgIWFLWB">https://t.co/a6BgIWFLWB</a> <a href="https://t.co/CpWTVTc87Y">pic.twitter.com/CpWTVTc87Y</a></p> — ABC Grandstand (@abcgrandstand) <a href="https://twitter.com/abcgrandstand/status/1099806603681751040?ref_src=twsrc%5Etfw">February 24, 2019</a></blockquote> <p>However, the cartoon was deemed by the Australian media watchdog in a “highly animated tantrum”. </p> <p>"Specifically, concern was expressed that the cartoon depicted Ms Williams with large lips, a broad flat nose, a wild afro-styled ponytail hairstyle different to that worn by Ms Williams during the match, and positioned in an ape-like pose," the Australian Press Council said.</p> <p>The Council noted the publication “failed to take reasonable steps to avoid causing substantial offence, distress or prejudice without sufficient justification in the public interest.”</p>
