Former pilot accused of murder shares his version of events

Former Jetstar pilot Greg Lynn has shared his version of events from the day Russell Hill and Carol Clay were allegedly murdered. Mr Lynn, who is on trial for the murders of the elderly campers, claimed Mr Hill, 74, knifed himself in a struggle after he accidentally shot his childhood sweetheart Ms Clay, 73, in the head. Police allege Mr Hill and Ms Clay were murdered while camping in the remote Wonnangatta Valley in Victoria's Alpine region more than four years ago, with Crown prosecutor Daniel Porceddu telling the jury at the opening of the trial exactly how and why Lynn allegedly killed the couple. "The precise circumstances of the killing are unknown, nor is the motivation," he said. The jury heard it was most likely a dispute over the use Mr Hill's drone, as Mr Porceddu said, "There might have been an argument or confrontation between the men. It is not known how Mr Hill was killed." But in providing a brief defence, Lynn's barrister Dermot Dann KC, claimed Mr Hill and Ms Clay's death was the result of a tragic accident, telling the jury, "We say not a case of murder, this is a case of two accidental, tragic deaths." "Tragic accidental deaths in circumstances that were not of Mr Lynn's making and not of his choosing." Mr Dann told the jury that Mr Hill allegedly stole Lynn's shotgun after he became enraged about Lynn playing loud music on the night he was killed. The barrister then detailed how a fight over the gun ensued, which resulted in Mr Hill accidentally shooting Ms Clay in the head, as Mr Lynn tried to disarm him. Mr Dann said Lynn picked up the gun and fired its remaining ammunition into the air before being set upon by an enraged Mr Hill. "The next thing is Mr Hill's advancing towards him with a knife screaming at him 'she's dead'," Mr Dann said. "A struggle developed over the knife. Mr Lynn trying to defend himself - they're locked in this struggle - and as part of that struggle the two men fall to the ground and the knife goes through the chest of Mr Hill." Upon his arrest, Mr Dann claimed Lynn co-operated with detectives, telling them where to find the bodies of the campers, and once again telling the jury that Mr Lynn is not guilty of murder or manslaughter.

"A step too far": Grandparents barred from school event for bizarre reason

A Melbourne school has come under fire for refusing to let a group of grandparents into the classroom for a special event because they did not have a Working With Children Check (WWCC). Furious grandparents have slammed St Joseph’s Primary School in Yarra Junction for taking it "a step too far" when they asked them to provide the WWCC after being invited to attend the “Inquiry Afternoon”. The event was held for year one and two students to speak about “technology and the world has changed over time”, according to The Herald Sun. Grandparents were asked to provide a WWCC on the back of the invitation, which some of them missed. “The Working With Children Check isn’t set up for the one-off visit — it is a step too far,” founder of the National Grandparent Movement Ian Barnett told Sunrise. “I understand we’re living in a time when we want more checks and balances, but it is unrealistic to think that grandparents attending such a day would actually need to go and provide a Working With Children Check." The grandparents without a WWCC were forced to sit in the principal's office and do their show-and-tell via a video call. “I’m sure they had very good intentions — no one set out for this to happen,” Herald Sun education editor Susie O’Brien said. “But imagine turning up, arranging your entire week, your day to come to your grandchild’s event … and the child’s school refuses entry.” She added that although schools did have some discretion over such requirements, when a group of people are invited for a specific event, it is usually not required. Barnett also said that "for such visits you don’t need a Working With Children Check,” in most states. “I haven’t heard of this in NSW. I have to admit, I’m from NSW. So it is really going a bit extreme. Schools do have the right to decide who comes onsite. But it just seems it’s not required. “To actually drag the child out from the classroom to sit with nana or grandad, it’s a step too far and embarrassing, I think, for the school as well.” A spokesperson for the primary school acknowledged that although there was some confusion, the school had to comply with the child safe standards. “There was advance notice to all St Joseph’s families on this requirement, with 29 grandparents signing in on Friday with a working with children clearance," they told the Herald Sun. “We acknowledge the disappointing experience of the four grandparents who couldn’t attend the grandparents’ day and are attempting to call these families this morning.” Images: Sunrise/ The Herald Sun

How extreme dieting can affect bone health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> 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. 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. 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. 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. 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. 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. <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. <figure class="align-center "><img src="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=338&fit=crop&dpr=1 600w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=338&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=338&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=424&fit=crop&dpr=1 754w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=424&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/591182/original/file-20240430-18-u30byz.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=424&fit=crop&dpr=3 2262w" alt="The interior of bones, showing four depictions of bone density – from healthy to severe osteoporosis." /><figcaption>The more crystals detected, the better your bone density. <a class="source" href="https://www.shutterstock.com/image-illustration/osteoporosis-4-stages-one-picture-3d-524364046">Crevis/ Shutterstock</a></figcaption></figure> 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. <h2>Bone density</h2> 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>. 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. 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. 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. 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. <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. <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. 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. 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>. <h2>Can bone health be fixed?</h2> 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>. 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.<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/228321/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does hosting the Olympics, the World Cup or other major sports events really pay off?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ivan-savin-678930">Ivan Savin</a>, <a href="https://theconversation.com/institutions/escp-business-school-813">ESCP Business School</a> After a long battle, <a href="https://www.france24.com/en/europe/20240213-paris-booksellers-stay-olympics-macron-bouquiniste-france">Paris’s beloved bouquinistes will be staying put</a> this summer. The decision, announced on 13 February by the French government, came after considerable public backlash to the police prefecture’s original plan to move part of the iconic Seine booksellers elsewhere for the inauguration of the Olympics Games on 26 July. Meanwhile, less than six months away from the event, Parisians continue to grumble over a <a href="https://www.ouest-france.fr/jeux-olympiques/cest-aberrant-ce-maire-vient-dapprendre-que-sa-ville-accueillera-les-jeux-de-paris-ab1fa968-cfd1-11ee-89c0-6cefac77e04a">lack of consultations</a> with locals, warnings of <a href="https://www.rfi.fr/en/france/20231130-paris-vehicle-traffic-to-be-heavily-restricted-during-2024-olympic-games">gridlocked traffic</a>, closed metro stations, extensive video surveillance and other grievances. So for host countries, what was the point of the Olympics, again? In academia, the debate about the potential positive and negative effects of large-scale sporting events is ongoing. Although these events are often associated with substantial economic losses, the long-term benefits are the main argument in favour of hosting them. These include the development of material and soft infrastructure such as hotels, restaurants or parks. Big games can also help put the host region on the map as an attractive place for sports and cultural events, and inspire a better entrepreneurial climate. <h2>The pros and the cons of big sporting events?</h2> The cost of these benefits, as the Parisians have realised, is steep. Host countries appear to suffer from increased tax burdens, low returns on public investments, high construction costs, and onerous running cost of facilities after the event. Communities can also be blighted by noise, pollution, and damage to the environment, while increased criminal activity and potential conflicts between locals and visitors can take a toll on their quality of life. As a result, in the recent past several major cities, including Rome and Hamburg, <a href="https://www.dw.com/en/6-cities-that-rejected-the-olympics/a-46289852">withdrew their bids to host the games</a>. A common feature of the economics of large-scale sporting events is that our expectations of them are more optimistic than what we make of them once they have taken place. Typically, expenditure tends to tip over the original budget, while the revenue-side indicators (such as the number of visitors) are rarely achieved. When analysing the effect of hosting large-scale sporting events on tourist visits, it is important to take into consideration both the positive and negative components of the overall effect. While positive effects may be associated with visitors, negative effects may arise when “regular” tourists refuse to visit the location due to the event. This might be because of overloaded infrastructure, sharp increases in accommodation costs, and inconveniences associated with overcrowding or raucous or/and violent visitors. On top of that, reports of poverty or crime in the global media can actually undermine the location’s attractiveness. <h2>When big sporting events crowd out regular tourists</h2> In an <a href="https://doi.org/10.1177/1527002523120639">article published in the Journal of Sports Economics</a> with Igor Drapkin and Ilya Zverev, I assess the effects of hosting large-scale sporting events, such as Winter and Summer Olympics plus FIFA World Cups, on international tourist visits. We utilise a comprehensive dataset on flow of tourists covering the world’s largest destination and origin countries between 1995 and 2019. As a first step, we built an econometric model that effectively predicts the flow of tourists between any pair of countries in our data. Subsequently we compared the predicted tourist inflow in a hypothetical scenario where no large-scale sporting event would have taken place with the actual figures. If the actual figures exceed the predicted ones, we consider the event to have a net positive impact. Otherwise, we consider that it had a “crowding out” effect on “regular” tourists. While conducting this analysis, we distinguished between short-term (i.e., focusing just on the year of the event) and mid-term (year of the event plus three subsequent years). Our results show that the effects of large-scale sporting events vary a lot across host countries: The World Cup in Japan and South Korea 2002 and South Africa 2010 were associated with a distinct increase in tourist arrivals, whereas all other World Cups were either neutral or negative. Among the Summer Olympics, China in 2008 is the only case with a significant positive effect on tourist inflows. The effects of the other four events (Australia 2000, Greece 2004, Great Britain 2012, and Brazil 2016) were found to be negative in the short- and medium-term. As for the Winter Olympics, the only positive case is Russia in 2014. The remaining five events had a negative impact except the one-year neutral effect for Japan 1998. Following large-scale sporting events, host countries are therefore typically less visited by tourists. Out of the 18 hosting countries studied, 11 saw tourist numbers decline over four years, and three did not experience a significant change. <h2>The case for cautious optimism</h2> Our research indicates that the positive effect of hosting large-scale sporting events on tourist inflows is, at best, moderate. While many tourists are attracted by FIFA World Cups and Olympic games, the crowding-out effect of “regular” tourists is strong and often underestimated. This implies that tourists visiting for an event like the Olympics typically dissuade those who would have come for other reasons. Thus, efforts to attract new visitors should be accompanied by efforts to retain the already existing ones. Large-scale sporting events should be considered as part of a long-term policy for promoting a territory to tourists rather than a standalone solution. Revealingly, our results indicate that it is easier to get a net increase in tourist inflows in countries that are less frequent destinations for tourists – for example, those in Asia or Africa. By contrast, the United States and Europe, both of which are traditionally popular with tourists, have no single case of a net positive effect. Put differently, the large-scale sporting events in Asia and Africa helped promote their host countries as tourist destinations, making the case for the initial investment. In the US and Europe, however, those in the last few decades brought little return, at least in terms of tourist inflow.<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/222118/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ivan-savin-678930">Ivan Savin</a>, Associate professor of quantitative analytics, research fellow at ICTA-UAB, <a href="https://theconversation.com/institutions/escp-business-school-813">ESCP Business School</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Travel Tips

Dog care below freezing − how to keep your pet warm and safe from cold weather, road salt and more this winter

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/erik-christian-olstad-1505284">Erik Christian Olstad</a>, <a href="https://theconversation.com/institutions/university-of-california-davis-1312">University of California, Davis</a> Time outside with your dog in the spring, summer and fall can be lovely. Visiting your favorite downtown café on a cool spring morning, going to a favorite dog park on a clear summer evening or going on walks along a river when the leaves are changing color are all wonderful when the weather is favorable. But in much of the country, when winter rolls around, previously hospitable conditions can <a href="https://theconversation.com/is-winter-miserable-for-wildlife-108734">quickly turn chilly and dangerous</a> for people and pups alike. Winter brings some unique challenges for dog owners, since dogs still need activity and socialization during colder seasons. Studies have shown that dog owners are almost 50% less likely to walk their dogs <a href="https://doi.org/10.3390/ani11113302">when the weather gets cold</a>. Knowing the basics of winter safety is critical to maintaining a healthy lifestyle for your dog. I am an <a href="https://www.vetmed.ucdavis.edu/faculty/erik-olstad">assistant professor</a> at the University of California Davis School of Veterinary Medicine who weathered polar vortexes with my dog while living in Michigan early in my career. While I’ve since moved to sunny California, I’ve seen how quickly frigid temperatures can turn dangerous for pets. <h2>Breed and age differences</h2> Not all dogs have the same abilities to deal with cold weather. A short-coated dog like a Chihuahua is much more susceptible to the dangers of cold weather than a thick-coated husky. When the weather dips below 40 degrees Fahrenheit (4 degrees Celsius), the well-acclimated husky may be comfortable, whereas the Chihuahua would shiver and be at risk of hypothermia. Additionally, if your dog is used to warm weather, but you decide to move to a colder region, the dog will need time to acclimate to that colder weather, even if they have a thick coat. Age also affects cold-weather resilience. Puppies and elderly dogs can’t withstand the chill as well as other dogs, but every dog is unique – each may have individual health conditions or physical attributes that make them more or less resilient to cold weather. <h2>When is my dog too cold?</h2> Pet owners should be able to recognize the symptoms of a dog that is getting too cold. Dogs will shiver, and some may vocalize or whine. Dogs may resist putting their feet down on the cold ground, or burrow, or try to find warmth in their environment when they are uncomfortable. Just like people, <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">dogs can get frostbite</a>. And just like people, the signs can take days to appear, making it hard to assess them in the moment. The most common sites for frostbite in dogs are their ears and the tips of their tails. Some of the initial signs of frostbite are skin discoloring, turning paler than normal, or purple, gray or even black; red, blistered skin; swelling; pain at the site; <a href="https://www.britannica.com/science/ulcer">or ulceration</a>. Other <a href="https://vcahospitals.com/know-your-pet/frostbite-in-dogs">serious signs of hypothermia</a> include sluggishness or lethargy, and if you observe them, please visit your veterinarian immediately. A good rule to live by is if it is too cold for you, it is too cold for your dog. Getting your dog a <a href="https://www.cnn.com/cnn-underscored/pets/best-winter-dog-coats-jackets">sweater or jacket</a> and <a href="https://www.akc.org/expert-advice/vets-corner/protect-dogs-paws-snow-ice-salt/">paw covers</a> can provide them with protection from the elements and keep them comfortable. Veterinarians also recommend closely monitoring your dog and limiting their time outside when the temperature nears the freezing point or drops below it. <h2>Road salt dangers</h2> Road salt that treats ice on streets and sidewalks <a href="https://www.cbc.ca/news/canada/kitchener-waterloo/ice-salt-toxic-for-pets-1.5020088">can also harm dogs</a>. When dogs walk on the salt, the sharp, rough edges of the salt crystals can irritate the sensitive skin on their paws. Dogs will often lick their feet when they’re dirty, wet or irritated, and if they ingest any salt doing that, they may face GI upset, dehydration, kidney failure, seizures or even death. Even small amounts of pure salt can <a href="https://www.petpoisonhelpline.com/pet-tips/my-dog-ate-road-salt-will-they-be-okay/">disrupt critical body functions</a> in dogs. Some companies make pet-safe salt, but in public it can be hard to tell what type of salt is on the ground. After walking your dog, wash off their feet or boots. You can also keep their paw fur trimmed to prevent snow from balling up or salt collecting in the fur. Applying a thin layer of petroleum jelly or <a href="https://www.akc.org/expert-advice/lifestyle/how-to-make-your-own-paw-balm-for-winter/">paw pad balm</a> to the skin of the paw pads can also help protect your pet’s paws from irritation. <h2>Antifreeze risks</h2> <a href="https://www.britannica.com/science/antifreeze-chemical-substance">Antifreeze, or ethylene glycol</a>, is in most vehicles to prevent the fluids from freezing when it gets cold out. Some people pour antifreeze into their toilets when away from their home to prevent the water in the toilet from freezing. Antifreeze is an exceptionally dangerous chemical to dogs and cats, as it tastes sweet but can be deadly when ingested. If a pet ingests even a small amount of antifreeze, the substance causes a chemical cascade in their body that results in severe kidney damage. If left untreated, the pet may have <a href="https://www.petpoisonhelpline.com/pet-owner-blog/antifreeze-poisoning/">permanent kidney damage or die</a>. There are safer antifreeze options on the market that use ingredients other than ethylene glycol. If your dog ingests antifreeze, please see your veterinarian immediately for treatment. When temperatures dip below freezing, the best thing pet owners can do is keep the time spent outside as minimal as possible.

Sydneysiders witnessed horrific scenes on Saturday. How do you process and recover from such an event?

<a href="https://theconversation.com/profiles/kim-felmingham-9075">Kim Felmingham</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Like many, I watched the reports of the violent attack at Bondi Junction yesterday with shock, horror and disbelief. My heart goes out to the people involved, the courageous first responders and to those who have lost loved ones in this tragic event. I also feel for those who witnessed the horror and will be working out how to get through the initial shock and, over time, put it behind them. Distress and strong emotional reactions are <a href="https://kclpure.kcl.ac.uk/portal/en/publications/the-psychological-and-psychiatric-effects-of-terrorism-lessons-fr">common</a> after these types of mass violent events. But different people will have <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">different emotional reactions</a> – and some may experience a range of shifting emotions. <h2>The first few days and weeks</h2> In the days and weeks after traumatic events like these, people <a href="https://www.ptsd.va.gov/understand/isitptsd/common_reactions.asp#:%7E:text=All%20kinds%20of%20trauma%20create,stop%20thinking%20about%20what%20happened.">often experience</a> a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306457320308670">range of emotions</a>: from fear and anxiety, anger, sadness and grief, disbelief and numbness, guilt and worry about safety. They may be jittery, more irritable or on edge, or it may affect their sleep. For many, their sense of risk may be heightened, particularly as such random violence occurred during such an ordinary event – shopping on a Saturday afternoon. This <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">can lead to</a> a heightened awareness of danger and concern for safety. <h2>What’s likely to happen over time?</h2> For most people, as they begin to process and make sense of what happened, these feelings will gradually reduce in intensity and people will begin to recover. <a href="https://pubmed.ncbi.nlm.nih.gov/25311288/">Research shows</a> the majority of people recover from mass violent events within the initial few months. However, for people with more direct exposure to the trauma, these events and reactions may be more difficult to process. Some people <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">may go on</a> to develop mental health difficulties, most commonly anxiety, depression and post-traumatic stress disorder (PTSD). Understandably, those <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">more at risk</a> are people who were present during the trauma and experienced a direct threat, as well as those who witnessed the violence or aftermath, first responders (paramedics and police) and those who had loved ones injured or lost during the event. People who had more intense emotional responses during the trauma, or previous psychological difficulties or traumatic experiences, may also be <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">at greater risk</a>. <h2>What helps – and hinders – your recovery?</h2> To help process these traumatic events and promote recovery, social support is <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">particularly important</a>. Spending time with trusted family and friends can help people process the events and their emotional reactions. Talking about your feelings with supportive people can help you understand and accept them. But even if you don’t want to talk about your feelings, spending time with loved ones is helpful. It is also fine to need some time to be alone, but try not to isolate yourself or withdraw. If you can’t talk about your feelings, try not to bottle them up or deal with them by using alcohol or drugs. Find <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7957853/">another way to express them</a> – whether through writing, art or music, or exercise. Give yourself permission and time to feel these emotions. Remind yourself you have just been through something extremely traumatic, take things day by day, and don’t expect too much of yourself. Try not to judge yourself for your actions or how you are coping. Keep some structure in your day, setting small goals, and increase your self-care: eat well, rest (even if you can’t sleep well), try yoga or relaxation. When you’re ready, try to get back to your normal routine. Seek out information from <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7957853/">trusted sources</a>, but try to <a href="https://journals.sagepub.com/doi/10.1177/0886260517742915">avoid</a> being saturated by images or stories about the trauma, particularly graphic footage or speculation common on social media. <h2>What if children have witnessed it, too?</h2> If your children have been impacted, reassure them that they are safe and loved. When they are ready, talk to them gently about the trauma, acknowledge it and answer their questions. Encourage them to express their feelings and spend more time together doing family activities. Importantly, try to limit their exposure to graphic footage and images of the events in the media, and on social media. <h2>When to seek mental health care</h2> Reach out for professional mental health support if you experience ongoing difficulty with your emotional reactions, or if you’re having distressing memories of the trauma, difficulty sleeping or nightmares, or you want to avoid things that remind you of the traumatic event. Not everyone requires professional mental health support, but if you are experiencing these types of post-traumatic stress reactions a few weeks after the trauma, it’s important to speak to your GP to seek out professional support from psychologists or counselling services.

Major festival event cancelled after deadly find

Mardi Gras Fair Day has been cancelled four days out from the event after asbestos was discovered in Victoria Park, Sydney CBD. The organisers of the event, were informed of the site's contamination on Monday, with EPA officers finding positive results for bonded asbestos after undertaking tests earlier this week. Mardi Gras chef executive Gil Beckwith said that they are heartbroken after the decision was made, but the community's wellbeing is more important. “Fair Day is one of our most loved events, and is attended by over 70,000 people each year,” Beckwith said. “It breaks our heart to see this Sunday not go ahead, but given the safety concerns, we must put our communities’ wellbeing first. “The rest of our festival continues unchanged, offering many chances over the 17 days for our communities to come together in celebration and solidarity.” Other highlights including the Mardi Gras Parade and Bondi Beach Party will still go ahead as planned. This comes after the EPA confirmed that there is a widespread asbestos contamination with 22 sites across Sydney being affected, prompting the closure of parks, building sites, schools and train stations. Asbestos is a fibrous substance that can be trapped in the lungs if it's breathed in, and can lead to an increased risk in developing lung, ovary and throat cancer, according to the cancer council. Lord Mayor of Sydney Clover Moore said that it was an “incredibly disappointing” decision. “The NSW government and the EPA must make sure this never happens again,” she said. Asbestos has been found in two other city parks including Belmore Park in Haymarket and Harmony Park in Surry Hills. The Sydenham to Bankstown Rail Corridor sites including Campsie, Hurlstone Park, Dulwich Hill, Belmore, Wiley Park, Punchbowl and Marrickville have also been affected, with licensed removalists working hard to clear the sites. Over the coming week 32 more parks will be closed off, as they conduct more tests for contamination. “We urge everyone to avoid the mulched garden beds and mulched areas under trees at these parks while the inspections are being carried out,” a City of Sydney spokesperson said.

Travel Trouble

"Eventful walk home": Barnaby Joyce explains why he was found collapsed on footpath

Barnaby Joyce, the Nationals frontbencher, has recently found himself at the centre of public attention after a video surfaced showing him lying on a footpath in Canberra, seemingly in an inebriated state. In a statement to Seven's Sunrise on Monday morning, Joyce attributed the incident to mixing alcohol with prescription medication. “It was a very eventful walk home, wasn’t it,” he said to host Nat Barr. "I’m on a prescription drug, and they say certain things may happen to you if you drink, and they were absolutely 100 per cent right. They did.” Barr then replied: “So you mixed alcohol with prescription medication, did you, and this is what happened?” “That’s exactly what I said, yep,” Joyce responded. In the video footage captured on Lonsdale Street in Braddon, initially obtained by The Daily Mail, Joyce can be seen lying on his back, mumbling into his phone, prompting concerns from passersby. Prime Minister Anthony Albanese urged Joyce to provide a credible explanation. “People will certainly make their own judgements on that," Albanese told the ABC. "People will see that footage, they will look for an explanation that has some credibility and they’ll look for leadership from the leader of the Liberal Party and the leader of the National Party about this.” Treasurer Jim Chalmers expressed concern for Joyce's wellbeing, calling for an explanation while refraining from personal attacks. The incident has prompted discussions within political circles, with Nationals leader David Littleproud stating that Joyce would receive the necessary support. However, Joyce's decision to skip a party meeting where the incident was to be discussed indicates ongoing uncertainty surrounding the situation. Images: Sunrise / Seven

Yes, it’s getting more humid in summer. Here’s why

<a href="https://theconversation.com/profiles/steven-sherwood-272">Steven Sherwood</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Has Sydney felt more like Cairns lately? You’re not imagining it – millions of Australians up and down the east coast have sweltered through exceptionally high humidity in recent weeks. It’s due to normal weather patterns combined with a boost from global warming. Right now, the temperature of the sea surface is <a href="http://www.bom.gov.au/products/IDYOC052.Aus.SSTAnomaly.shtml">1–3°C above normal</a> for this time of year up and down the east coast. It’s particularly hot around the Queensland-New South Wales border and Tasmania’s east coast. When we have high ocean temperatures, we get more water evaporating. This is taken up by the air, which can hold more moisture when the air is hotter. This moist air is then carried to us by winds, and the sweating begins. <h2>Where does humidity come from?</h2> Humidity is just gaseous water held in the air after evaporating from liquid water or ice. It is called a vapour because it condenses into rain — the more humid, the more likely rain is. Higher humidity makes us feel hotter in warm weather, and slows the drying of laundry on a clothesline or of plants in the garden. How do we measure it? Two common ways are the “dew point” and “relative humidity”. At any given air temperature, there’s a limit to how much vapour the air will retain. Any vapour above this limit will just condense out. But the limit roughly doubles with every 10°C of warming; the dew point is the temperature where the vapour would hit the limit. The less vapour there is in the air, the colder the dew point. Relative humidity is the ratio of how much vapour the air has compared to the maximum it would retain. If you’re in Tasmania and see that relative humidity is at 100%, you might be confused. But this measure essentially tracks how “full” the air is. At 100% relative humidity, the dew point matches the actual temperature and no more vapour can be added. If the dew point is 10°C below the actual temperature, relative humidity is about 50%. How do we measure it? The dew point can be measured directly using a chilled mirror and a laser to detect condensation. More often it’s calculated from measurements of relative humidity and temperature. Relative humidity determines whether material exposed to the air will moisten or dry out. That’s why relative-humidity sensors use cheap water-absorbing materials (early ones used a strand of human hair!). <h2>What does a changing climate mean for humidity?</h2> The world’s higher ocean temperatures are unambiguously attributable to global warming, largely from the greenhouse gases we have added by burning fossil fuels. To date, more than 90% of all the extra heat thereby trapped has gone into the oceans. The amount of water vapour over the oceans has increased by roughly 5% since the industrial era began, in lockstep with global warming. Global warming will continue until we stop it. That means the atmosphere will keep getting more humid. If the world manages to keep global warming below 2°C, we should avoid the worst health outcomes from more humidity. But even then, we would expect up to another 5% increase in peak water vapour. Right now, we are seeing higher-than-normal temperatures in most of our surrounding oceans, with only a few exceptions. The areas hit hardest by rising humidity are mostly those that are already humid, like Queensland and the Northern Territory. Although peak dew points are rising, you may be confused to hear average relative humidity is actually <a href="https://www.pnas.org/doi/full/10.1073/pnas.1722312115">falling over land</a>. That’s because the land is warming so fast the average dew points aren’t quite keeping up with temperature, lowering the ratio. That means, alas, that Australia faces a double whammy: increasing water stress and bushfire risk as well as sweatier summers. <h2>Humidity can be very dangerous</h2> Our natural cooling system in hot weather is evaporation of sweat. Sweat forms on your skin, and the air evaporates it, taking the heat with it. But this only works to a point. When the dew point is higher, our self-cooling methods get less and less effective. How important this is depends on how hot you feel. On a moderate but muggy day, you might feel fine until you need to climb four flights of stairs and end up sweaty and exhausted. On a hotter but less muggy day you’d feel the heat at the outset, but would more easily handle the stairs. The Bureau of Meteorology uses something called “<a href="https://media.bom.gov.au/social/blog/1153/apparent-feels-like-temperature/">apparent temperature</a>” to capture the combined effect of temperature and humidity, although this assumes you’re not exerting yourself. How you feel with more exertion can be captured by other measures, such as the “wet bulb globe temperature” now being used at sporting events such as the Australian Open. The Bureau has recently begun providing <a href="http://www.bom.gov.au/places/nsw/sydney/forecast/detailed/">humidity and apparent temperature forecasts</a> as a beta product, which is great for activity planning. This type of information will become more important as the heat builds. As humidity increases during peak humid heat episodes, it makes heat stress worse and moves us toward our body’s physical limits. <a href="https://www.pnas.org/doi/10.1073/pnas.2316003120">Recent research</a> has shown the combination of humidity and heat could make parts of the planet unlivable if Paris Agreement targets are not met, beginning in India and spreading elsewhere in the tropics – including the Top End of Australia. We need to prepare now for increasing heat, while doing everything we can to stop the routine burning of fossil fuels as soon as possible to maintain a margin of safety for humanity.<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/221748/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/steven-sherwood-272">Steven Sherwood</a>, Professor of Atmospheric Sciences, Climate Change Research Centre, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What does El Niño do to the weather in your state?

<a href="https://theconversation.com/profiles/kimberley-reid-767059">Kimberley Reid</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> You’ve probably heard El Niño brings hot and dry weather to the eastern states, but what about the rest of Australia? Are we all in for a scorcher this summer? El Niño is what scientists call a <a href="https://www.climatechangeinaustralia.gov.au/en/overview/climate-system/australian-climate-influences/">climate driver</a>. But it’s just one of many. These climate drivers control year-to-year variations in the weather. Some years are hotter and drier, while others are cooler and wetter. Australia is particularly prone to weather whiplash because our continent is buffeted by climate drivers to our north, south, east and west. The dominant driver in your state may be one of the lesser-known influences. <figure><iframe src="https://www.youtube.com/embed/iVhi1wq2sTY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Understanding Climate Drivers (Bureau of Meteorology)</figcaption></figure> <h2>East: El Niño Southern Oscillation</h2> The El Niño Southern Oscillation (ENSO) is the resident climate driver in the Pacific Ocean and the driver with the biggest influence over Australian weather. Differences in sea surface temperatures and winds across the Pacific determine whether we swing towards El Niño (the boy) or La Niña (the girl). <a href="http://www.bom.gov.au/climate/about/?bookmark=enso">During the El Niño phase</a>, sea surface temperatures near South America are warmer than normal and they are cooler than normal off the coast of eastern Australia. Additionally, trade winds that blow from east to west across the Pacific weaken. El Niño brings hotter daytime temperatures, but often <a href="http://www.bom.gov.au/climate/enso/#tabs=Pacific-Ocean&pacific=History">cooler nights</a>. That’s because reduced cloud cover allows more heat to escape into space overnight. So the same process that increases the chances of heatwaves can also raise the <a href="https://www.agric.wa.gov.au/climate-weather/historical-frost-and-heat-maps-south-west-land-division">risk of frost</a> in Western Australia, New South Wales, the Australian Capital Territory and Victoria. Australia as a whole is typically drier during an El Niño event. In the tropical regions, El Niño can delay the <a href="http://www.bom.gov.au/climate/updates/articles/a008-el-nino-and-australia.shtml">onset of the monsoon and reduce the likelihood of tropical cyclones</a>. In the southern states, the hot and dry conditions increase the chance of intense bushfires. La Niña is the opposite phase. Waters off eastern Australia are warmer than usual, increasing the <a href="http://www.bom.gov.au/climate/enso/#tabs=Pacific-Ocean&pacific=History&enso-impacts=La-Ni%C3%B1a-impacts">chance of tropical cyclones</a> and an earlier start to the monsoon for WA, the Northern Territory and Queensland. So what does El Niño do to the weather in your state? Hover over your state in the interactive map to find out. <iframe id="tc-infographic-1008" class="tc-infographic" style="border: none;" src="https://cdn.theconversation.com/infographics/1008/7f37ae91389db072906b320ffd54d0fefd840c0d/site/index.html" width="100%" height="400px" frameborder="0"></iframe> <h2>West: Indian Ocean Dipole</h2> The <a href="http://www.bom.gov.au/climate/about/?bookmark=iod">Indian Ocean Dipole</a> is like ENSO’s Indian Ocean cousin. A positive Indian Ocean Dipole is declared when ocean temperatures near Africa are warmer than normal and ocean temperatures off the coast of Sumatra are cooler than usual. A positive dipole tends to bring warmer and drier conditions, particularly to western and central Australia. A negative Indian Ocean Dipole is the reverse and is associated with wetter than normal weather and an increase in <a href="https://pursuit.unimelb.edu.au/articles/why-more-clouds-can-mean-less-rain-in-australia">northwest cloudbands</a>. <h2>North: Madden-Julian Oscillation</h2> The <a href="http://www.bom.gov.au/climate/about/?bookmark=mjo">Madden-Julian Oscillation</a> is a pulse of storms that start in the Indian Ocean, travel over Northern Australia and Indonesia and die in the Pacific Ocean. Ahead of the pulse, the air sinks, causing sunny and dry weather. Under the pulse is high storm activity and typically heavy rainfall. We describe the Madden-Julian Oscillation based on whether the pulse of storms is <a href="http://www.bom.gov.au/climate/mjo/">active or inactive</a> and where the storm activity is located on its path between the Indian and Pacific Oceans. As well as causing rainfall, the Madden-Julian Oscillation can control the timing of the monsoon onset and <a href="http://www.bom.gov.au/climate/about/?bookmark=tc">tropical cyclone formation</a>. <h2>South: Southern Annular Mode</h2> The <a href="http://www.bom.gov.au/climate/about/?bookmark=sam">Southern Annular Mode</a> controls the north and south position of the westerly winds that whizz around the globe in the Southern Ocean. When the winds are further north than usual, we call this the negative phase. But when the westerly wind move towards Antarctica, we call this the positive phase. The phase of the Southern Annular Mode <a href="https://rmets.onlinelibrary.wiley.com/doi/abs/10.1002/joc.1370">affects how many weather systems</a>, like cold fronts, make landfall over southern Australia. A positive mode may also draw tropical moist air south, which happened in 2022 during the extensive flooding over eastern Australia. <h2>Climate drivers control the odds, but not the result</h2> These four key climate drivers affect the weather on average (over months and seasons), but they do not dictate the exact day-to-day weather we experience. As the Gippsland region of Victoria <a href="https://www.theguardian.com/australia-news/2023/oct/05/victoria-floods-flooding-warnings-gippsland-region-flood-and-fires-evacuation">saw in October</a>, heavy rainfall can still occur during an El Niño. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=407&fit=crop&dpr=1 600w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=407&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=407&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=512&fit=crop&dpr=1 754w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=512&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/561494/original/file-20231124-16-ip8fja.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=512&fit=crop&dpr=3 2262w" alt="Map of Australia showing the difference from normal rainfall during October 2023, with a large wet patch around Gippsland, Victoria." /></a><figcaption>Difference from normal rainfall during October 2023, showing defined wet area around Gippsland, Victoria surrounded by drier conditions.

They can select the best players and develop ingenious strategies, but that doesn’t guarantee a win every time. Players can get injured on the field or simply have a bad game. These uncontrollable factors are challenging to predict and may change the result from what we would expect. Scientists call this stochasticity. The climate drivers are the football coach, but the day-to-day weather systems are the players. The Bureau of Meteorology <a href="http://www.bom.gov.au/climate/enso/">releases an update</a> on all of these drivers every two weeks. The update explains which drivers are currently active and the forecast for the next few weeks.

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

<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> Australia is braced for a hot, dry summer.

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. Heat illnesses can vary, from relatively mild heat exhaustion to the potentially life-threatening condition of heat stroke. <h2>What are the signs and symptoms?</h2> If you’re suffering from heat exhaustion, you may feel weakness, nausea, headaches or dizziness. 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. 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. 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. When it comes to cooling someone with suspected heat stroke, the quicker the better: cool first, transport second. <h2>Why do we overheat?</h2> 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. 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. Sweating is by far our most effective physiological means of keeping cool. However, it is the evaporation of sweat from our skin that provides cooling relief. When the air is humid, it already contains a lot of moisture, and this reduces how efficiently sweat evaporates. 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. Finally, clothing can act as an insulator and barrier for the evaporation of sweat, making it even more difficult for us to keep cool. <h2>Who is most vulnerable in the heat?</h2> 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. 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. 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>. 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. 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. 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. 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. <h2>How to stay safe in the heat</h2> Thankfully, there are effective, low-cost <a href="https://twitter.com/TheLancet/status/1677702906789740545">ways</a> of staying safe in the heat.

Manu Feildel forced to pull out of major event after health emergency

Manu Feildel has explained a recent health scare, after he was forced to pull out of appearing at a major event. The celebrity chef and My Kitchen Rules judge was set to make a guest appearance at Sydney’s Tour de Cure Spring Lunch at Doltone House on Friday, but was hospitalised before he was expected to arrive. Feildel took to Instagram to explain his mysterious absence from the event, which was a charity luncheon to raise money for cancer research. “I wish I could be there celebrating with you, but unfortunately I have to go for surgery tomorrow,” he said in a video message. Whilst the cook did not say what his condition was, he later posted a video showing his leg in a heavy brace. Manu’s knee looked especially red and swollen, with dressing across the kneecap. “I’ve had some surgery done and I can’t cook for myself as I usually do,” he said in the clip. Fans flocked to the comments section to wish Manu well. “Look after your leg mon ami!” wrote fellow chef Luca Ciano. “Hope you’re ok.” “Manu, oh no. What happened?” wondered another follower, while one person quipped, “Too much sauce, and u slipped on it?” Another concerned fan asked: “What have you done to yourself now? Wishing you a speedy recovery,” while others posted a simple, “Get well soon.” Image credits: Instagram

Extreme weather is landing more Australians in hospital – and heat is the biggest culprit

<a href="https://theconversation.com/profiles/amy-peden-1136424">Amy Peden</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Hospital admissions for injuries directly attributable to extreme weather events – such as heatwaves, bushfires and storms – have increased in Australia over the past decade. A new <a href="https://www.aihw.gov.au/reports/injury/extreme-weather-injuries/contents/about">report</a> from the Australian Institute of Health and Welfare (AIHW) shows 9,119 Australians were hospitalised for injuries from extreme weather from 2012-22 and 677 people died from these injuries in the decade up to 2021. In 2021-22, there were 754 injury hospitalisations directly related to extreme weather, compared to 576 in 2011-12. Extreme heat is responsible for most weather-related injuries. Exposure to prolonged natural heat can result in physical conditions ranging from mild heat stroke, to organ damage and <a href="https://www.dea.org.au/wp-content/uploads/2021/01/DEA-Fact-Sheet_HeatwavesWEB.pdf">death</a>. As Australia heads into summer with an El Niño, it’s important understand and prepare for the health risks associated with extreme weather. <h2>A spike every three years</h2> Extreme weather-related hospitalisations have spiked at more than 1,000 cases every three years, with the spikes becoming progressively higher. There were: <ul> <li>1,027 injury hospitalisations in 2013–14</li> <li>1,033 in 2016–17</li> <li>1,108 in 2019–20.</li> </ul> <iframe id="vLaas" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/vLaas/1/" width="100%" height="400px" frameborder="0"></iframe> In each of these three years, extreme heat had the biggest impact on hospital admissions and deaths. <iframe id="P03sm" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/P03sm/1/" width="100%" height="400px" frameborder="0"></iframe> Extreme heat accounted for 7,104 injury hospitalisations (78% of all injury hospitalisations) and 293 deaths (43% of all injury deaths) in the ten year period analysed. In 2011-12, there were 354 injury hospitalisations directly related to extreme heat. This rose to 579 by 2021-22. <h2>El Niño and La Niña</h2> Over the past three decades, extreme weather events have increased in <a href="https://www.ipcc.ch/report/ar5/syr/">frequency</a> and <a href="http://www.bom.gov.au/state-of-the-climate/">severity</a>. In Australia, El Niño drives a period of reduced rainfall, warmer temperatures and increased bushfire danger. La Niña, on the other hand, is associated with above average rainfall, cooler daytime temperatures and increased chance of tropical cyclones and flood events. Although similar numbers of heatwave-related hospitalisations occurred in El Niño and La Niña years studied, the number of injuries related to bushfires was higher in El Niño years. During the 2019–20 bushfires, in the week beginning January 5 2020, there were 1,100 more hospitalisations than the previous five-year average, an 11% increase. Although El Niño hasn’t directly been proved as the cause for these three spikes, according to the Bureau of Meteorology, two of the three years (2016-17 and 2019-20) were El Niño summers. And the other year (2013-14) was the warmest neutral year on record at that time. <h2>Regional differences</h2> Exposure to excessive natural heat was the most common cause leading to injury hospitalisation for all the mainland states and territories. From 2019 to 2022, there were 2,143 hospital admissions related to extreme heat, including: <ul> <li>717 patients from Queensland</li> <li>410 from Victoria</li> <li>348 from NSW</li> <li>267 from South Australia</li> <li>266 from Western Australia</li> <li>73 from the Northern Territory</li> <li>23 from the ACT</li> <li>19 from Tasmania.</li> </ul> <figure class="align-center "><img src="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=632&fit=crop&dpr=1 600w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=632&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=632&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=794&fit=crop&dpr=1 754w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=794&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/556987/original/file-20231101-27-3c98xm.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=794&fit=crop&dpr=3 2262w" alt="" /><figcaption><a class="source" href="https://www.aihw.gov.au/reports-data/latest-reports">AIHW National Hospital Morbidity Database</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> The report also includes state and territory data on hospitalisations related to extreme cold and storms. During the ten-year period analysed, there were 773 injury hospitalisations and 242 deaths related to extreme cold. Extreme rain or storms accounted for 348 injury hospitalisations and 77 deaths. From 2019 to 2022, there were 191 hospitalisations related to extreme cold, with Victoria recording the highest number (51, compared to 40 in next-placed NSW). During the same period there were 111 hospitalisations related to rain and storms, with 52 occurring in NSW and 28 in Queensland. <h2>What about for bushfires?</h2> Over the ten-year period studied, there were 894 hospitalisations and 65 deaths related to bushfires. Bushfire-related injury hospitalisations and deaths peaked in 2019–20, an El Niño year with 174 hospitalisations and 35 deaths. The two most common injuries that result from bushfires are smoke inhalation and burns. During the 2019–20 bushfires, in the week beginning 5 January 2020 there were 1,100 more respiratory hospitalisations than the previous five-year average, an 11% increase. The greatest increase in the hospitalisation rate for burns was 30% in the week beginning December 15 2019 — 0.8 per 100,000 persons (about 210 hospitalisations), compared with the previous 5-year average of 0.6 per 100,000 (an average of 155 hospitalisations). <h2>Some people are particularly vulnerable</h2> Anyone can be affected by extreme weather-related injuries but some population groups are more at risk than others. This includes older people, children, people with disabilities, those with pre-existing or chronic health conditions, outdoor workers, and those with greater <a href="https://www.mdpi.com/2071-1050/15/1/813">socioeconomic disadvantage</a>. People in these groups may have reduced capacity to avoid or reduce the health impacts of extreme weather conditions, for example older people taking medication may be less able to regulate their body temperature. “Thermal inequity” includes people living in poor quality housing who have difficulty accessing adequate heating and cooling. For heat-related injuries between 2019–20 and 2021–22, people aged 65 and over were the most commonly admitted to hospital, followed by people aged 25–44. Across age groups, men had higher numbers of heat related injury hospitalisations than women. This difference was most notable among those aged 25-44 and 45-64 years, where over twice as many men were hospitalised due to extreme heat as women. <h2>We still don’t have a full picture</h2> The AIHW data only includes injuries which were serious enough for patients to be admitted to hospital; it doesn’t include cases where patients treated in an emergency department and sent home without being admitted. It includes injuries that were directly attributable to weather-related events but does not include injuries that were indirectly related. For example, it doesn’t include injuries from road traffic accidents that occur due to wet weather, since the primary cause of injury would be recorded as “transport”. Improved surveillance of weather-related injuries could help the health system and the community better prepare for responding to extreme weather conditions. For example, better data aids communities in predicting what resources will be needed during periods of extreme weather. A more complete picture of injuries during weather events could also be used to inform people of actions they can take to protect their own health. Given a predicted hot summer, this could be a matter of life or death.

"It was beautiful": Rare rainbow cloud stuns small farming town

The locals of a small farming town in Western Australia have been delighted with the sighting of a rare rainbow cloud. The colourful weather phenomenon appeared above the town of Goomalling, about 130km northwest of Perth in Western Australia, on Tuesday morning. Jenni Shaw was at her family-owned business when she got a text from a friend instructing her to look up at the sky. "We all went out the front and had a look and there was some bright, rainbow-type clouds in the sky that we hadn't seen before," she told <a href="https://www.abc.net.au/news/2023-10-24/rainbow-cloud-iridescence-irisation-delights-wheatbelt-community/103016928" target="_blank" rel="noopener">ABC</a>. “It was beautiful,” she said. “But we were a bit like ‘why is that like that?

4 ways to support someone with dementia during extreme heat

<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> 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. 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>. But as the temperature rises, friends, relatives and carers can help. <h2>El Niño means there are challenges ahead</h2> 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. Extreme heat and bushfires bring unique challenges for someone with dementia. 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. 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. Emergency evacuations can also be confusing and distressing for a person with dementia, so it is important to think ahead. <h2>Why are people with dementia more at risk?</h2> 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. 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. 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. A person with dementia can also wander and become lost, which can be dangerous in extreme heat. <h2>4 ways to support someone with dementia</h2> 1. Avoid dehydration and heatstroke 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>. 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. 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. 2. Cool the home 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. 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. Try to support the person to make suitable clothing choices for the season by having cool, lightweight options easily available. 3. Think about communications early If someone with dementia lives alone, consider how you will maintain contact in an emergency. 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. 4. Have an evacuation plan 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. The situation can change quickly in an emergency, and this can be particularly overwhelming for people with cognitive issues. 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. Stay up-to-date with <a href="http://www.bom.gov.au/">current warnings</a> and act early whenever possible. <h2>We can all help</h2> 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. 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" /> <a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, Postdoctoral Research Fellow, Neuroscience Research Australia (NeuRA), <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

They <a href="https://theconversation.com/feel-like-youre-a-mozzie-magnet-its-true-mosquitoes-prefer-to-bite-some-people-over-others-128788">need blood</a> – but water and warmth are just as important. Getting rid of water around your backyard will go a long way to keeping mosquitoes away. Water trapped in blocked roof gutters, drains and tarpaulin covering boats and trailers can be a great home for mosquitoes. Mosquitoes can exploit the tiniest of water sources too. It may just be the upturned lid of a discarded plastic drink bottle. If it traps water, mosquitoes will find it and lay eggs in it. Flush out your bird bath once a week to disrupt the mosquito’s life cycle. If you have a pond, installing a fountain will discourage mosquitoes. If you can’t keep water clean and circulating, consider filling it with sand and gravel to create an interesting garden bed for succulents or other plants. Mosquitoes will avoid clean and chlorinated swimming pools but will quickly move into “green pools”. If you’re not using your pool, consider <a href="https://www.krg.nsw.gov.au/Environment/Your-local-environment/Wildlife/Living-with-wildlife/Pool-to-pond/How-to-convert-your-pool">converting it to a “pond”</a> so that fish can help keep mosquito numbers down. <h2>2. Screen up – windows, doors and rainwater tanks</h2> If you can’t get rid of permanent water, at least stop mosquitoes getting to it (or you). Ensure <a href="https://www.brisbane.qld.gov.au/clean-and-green/natural-environment-and-water/water/water-smart-homes/rainwater-tanks/using-your-rainwater-tank">rainwater and septic tanks</a> have screens to stop mosquitoes entering. Screen windows and doors to stop mosquitoes entering the home. There are plenty of flexible screening options for windows, doors and balconies. If you live in a mosquito-prone area, creating a screened outdoor area (such as a pergola, courtyard, or balcony) will give you the opportunity to spend time outdoors without being hassled by mozzies. <h2>3. Choose your garden plants carefully</h2> Some plants <a href="https://bioone.org/journals/Journal-of-the-American-Mosquito-Control-Association/volume-25/issue-3/09-0016.1/Are-Commercially-Available-Essential-Oils-from-Australian-Native-Plants-Repellent/10.2987/09-0016.1.short">contain essential oils and other chemicals</a> that, when extracted and concentrated, provide protection against biting mosquitoes. But there isn’t a lot of evidence that the whole plant will keep mosquitoes away from your garden. Some types of plants are even marketed as “mozzie blockers” or “mosquito repelling”. But there isn’t <a href="https://www.veranda.com/outdoor-garden/a40592197/do-mosquito-repelling-plants-work/">any evidence of effectiveness</a>. In fact, some of these plants, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1440-6055.2009.00736.x">such as melaleucas</a>, also happen to be associated with <a href="https://academic.oup.com/jme/article/36/4/515/903838">hot spots of mosquito breeding</a> in coastal Australia. The plants to avoid around the home are those that help mosquitoes breed, such as <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1440-6055.2008.00641.x">bromeliads</a>, which trap water. <h2>4. Encourage the animals that eat mosquitoes</h2> Mosquitoes are food for a range of animals including birds, bats, fish, frogs, lizards, insects, spiders and <a href="https://besjournals.onlinelibrary.wiley.com/doi/abs/10.1111/1365-2656.13965">dragonflies</a>. But don’t expect them to eat enough to keep all mosquitoes away. Bats are often promoted as a good “biological control” options but studies have shown mosquitoes are <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0077183">more likely to be a snack food</a> for small bats, not an irresistible staple of their diet. For garden ponds, frogs will eat a few adult mosquitoes but tadpoles of Australian frogs generally <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-21/issue-4/8756-971X(2006)21%5b492%3aTOFCAF%5d2.0.CO%3b2/TADPOLES-OF-FOUR-COMMON-AUSTRALIAN-FROGS-ARE-NOT-EFFECTIVE-PREDATORS/10.2987/8756-971X(2006)21%5B492:TOFCAF%5D2.0.CO;2.short">don’t eat many mosquito “wrigglers”</a>. Australian native fish <a href="https://pubmed.ncbi.nlm.nih.gov/15532929/">will readily eat mosquitoes</a> and may be useful for backyard ponds. But not all fish are good. While “mosquitofish” (aka “plague minnow”) is distributed overseas to assist in mosquito control, <a href="https://meridian.allenpress.com/australian-zoologist/article/30/3/316/134508/Does-predation-by-the-fish-Gambusia-holbrooki">it’s a disaster for local wildlife</a> and, <a href="https://www.dpi.nsw.gov.au/fishing/aquatic-biosecurity/pests-diseases/freshwater-pests/finfish-species/gambusia">along with other exotic fish species</a>, should not be released into local waterways. <a href="https://link.springer.com/article/10.1007/s13157-019-01133-2">Healthier habitats promote fewer mosquitoes</a> so the best thing you can do is create habitats for the animals that eat mosquitoes. <h2>5. Avoid traps and other gadgets</h2> There are lots of devices purported to catch, kill, or repel mosquitoes from your garden. Some may catch a mosquito or two but they’re not very effective in knocking out big numbers. “Bug zappers” with bright lights will collect lots of flying insects. It’s just that mosquitoes make up a very small proportion of collections. Electrocuting devices, again, don’t seem to attract a lot of mosquitoes. Devices that <a href="https://theconversation.com/the-buzz-from-your-smartphone-wont-stop-mosquito-bites-92611">emit high frequency sounds</a> won’t help either. The best devices are typically those that are baited with carbon dioxide. These are a mainstay of state and territory <a href="https://www.health.nsw.gov.au/Infectious/mosquito-borne/Pages/surveillance.aspx">mosquito and arbovirus surveillance programs</a>. For a mosquito, the C0₂ tricks them into thinking the trap is a warm-blooded animal. The only problem is these can be expensive to run and don’t seem quite as effective for mosquito control <a href="https://bioone.org/journals/journal-of-the-american-mosquito-control-association/volume-22/issue-3/8756-971X(2006)22%5b490%3aTATTFA%5d2.0.CO%3b2/Traps-and-Trapping-Techniques-for-Adult-Mosquito-Control/10.2987/8756-971X(2006)22%5B490:TATTFA%5D2.0.CO;2.short">unless used in large numbers</a>. <h2>Yes, you’ll still need repellent</h2> Perhaps the best way to avoid mosquito bites is to pick an insect repellent <a href="https://www.phrp.com.au/issues/december-2016-volume-26-issue-5/a-review-of-recommendations-on-the-safe-and-effective-use-of-topical-mosquito-repellents/">recommended by health authorities</a> and <a href="https://theconversation.com/mozzies-biting-heres-how-to-choose-a-repellent-and-how-to-use-it-for-the-best-protection-150183">apply it</a> to ensure all exposed areas of skin are covered. These products and safe, affordable and effective.<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/212711/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, Clinical Associate Professor and Principal Hospital Scientist, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

10 driving tips to stay safe in wet weather

Driving in the rain? Follow these tips for safe driving in wet weather This should go without saying, but reducing your speed – as long as you continue to keep with the flow of traffic, of course – is imperative when driving in the rain. After all, between the downpour and spray from other vehicles, heavy rain reduces visibility in all directions, and you need more time to react. Keep your distance Driving in the rain can be hazardous, and if ever there is an incident that requires you – or the driver in front you – to brake unexpectedly, you’ll want to have ample stopping distance on wet roads. Avoid heavy breaking While driving in the rain, you may find yourself in situations – whether you’re hydroplaning or finding yourself in a skid – that will tempt you to hit the brakes abruptly. Do your best to curb that impulse. Brakes can be affected greatly by water, losing a bit of their power when wet, which can be disastrous in an emergency. Easing off the brakes, slowing down and maintaining control of your vehicle is your best bet. Keep both hands on the wheel Control is of utmost importance when driving in the rain. After all, you need to be in command of your vehicle should an incident occur, and having both hands on the wheel while driving in the rain (no snacking or fiddling with the radio!) will ensure you can get out of a sticky situation quickly and efficiently. Keep windows from fogging up When driving in rain, windows tend to fog up as a result of the difference in temperatures inside and outside the car and can lead to decreased visibility. To stay safe and avoid accidents, simply press your car’s defrost button to clear-up the window. Turn on your A/C or roll down the windows by a couple of centimetres to remove the humidity from the vehicle and lower the temperature inside the car. If the issue persists, you may want to purchase a windshield cleaner and defogger. Beware of hydroplaning Hydroplaning happens when your car travels above the water without touching the ground. Given that a driver is left with little-to-no grip with the road and, thus, less control, this can be a dangerous set of circumstances. If you find yourself in such a situation, stay calm, ease off the brakes and do not turn your steering wheel; let your car slow down and the tires reattach to the road surface. Avoid puddles Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain. Stay home if you can If you have no choice but to head outside during a heavy downpour, be sure to follow these driving tips. However, if you don’t have anywhere pressing to be, consider staying home and waiting it out until the storm subsides. Keep your headlights on With wet weather often comes fog and overall gloominess. With your surroundings slightly darkened, turning on your headlights ensures that you can see the road in front of you, and that other drivers can see you. Ensure windshield wipers are in working order Windshield wipers should always be in working condition. Be vigilant about replacing them once per year, or whenever they start to leave streaks on the glass. Having wipers blades in tip-top shape ensures the best possible visibility when driving in the rain.

How climate change will affect your pet – and how to help them cope

<a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Earth has just experienced its <a href="https://www.theguardian.com/science/2023/jul/27/scientists-july-world-hottest-month-record-climate-temperatures">hottest month</a> since records began and Australia is now gearing up for an El Niño-fuelled summer. Extreme heat isn’t just challenging for humans – it brings suffering to our beloved pets, too. <a href="https://www.cabidigitallibrary.org/doi/10.1079/cabireviews.2023.0020">Research</a> I was involved in examined how climate change affects the welfare of animals, including pets. My colleagues and I used a concept for assessing animal welfare known as the “<a href="https://kb.rspca.org.au/knowledge-base/what-are-the-five-domains-and-how-do-they-differ-from-the-five-freedoms/">five-domains model</a>”. It’s a science-based structure for examining an animal’s: <ul> <li>nutrition</li> <li>environment</li> <li>physical health</li> <li>behaviour</li> <li>mental state.</li> </ul> The model evaluates the complete physiological and behavioural responses of animals to environmental stressors. While the effects of climate change on animals have been studied before, ours is the first study to apply the model to animal welfare specifically. We examined the academic literature and found climate change will harm animals across all five welfare domains. This applies to both wild and domesticated animals, including pets. So let’s take a look at how various types of pets will fare in a warming world – and how we can help them. <h2>Fish</h2> Fish are “ectotherms” – that is, they use external sources of heat to regulate their body temperature. So pet fish are vulnerable to changes in the water temperature of your home aquarium, which may occur during a heatwave. Extreme water temperatures can cause physical harm to fish. For example, it can increase a fish’s metabolic rate – meaning it <a href="https://e360.yale.edu/features/feeling-the-heat-warming-oceans-drive-fish-into-cooler-waters">needs more oxygen</a> to breathe . It can also <a href="https://www.nepjol.info/index.php/ON/article/view/4331">cause changes</a> such as slowed growth and reduced feeding. According to <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/other-pets/caring-for-your-pet-fish">official advice</a>, water in an indoor aquarium should generally be kept at between 20℃ and 25℃ (unless you are keeping tropical fish). Depending on your budget and aquarium size, you could opt to use a device to control the water temperature. Either way, it’s important to monitor the water temperature regularly. Also make sure the aquarium isn’t located near a window where it’s exposed to direct sunlight. Leaving your aquarium unattended for days or weeks in summer can be dangerous, due to the risk of heatwaves. If you’re going on a summer holiday, consider organising a <a href="https://www.thesprucepets.com/holiday-and-vacation-fish-care-and-feeding-1378525#:%7E:text=If%20you%20are%20going%20on,aquarium%20and%20can%20prove%20lethal">fish sitter</a> to check on the animal regularly. <h2>Birds</h2> Heat stress can change the <a href="https://www.vetexotic.theclinics.com/article/S1094-9194(16)00003-7/fulltext">physiology</a> of birds. For example, research into a wild population of small Australian robins showed during a heatwave, the birds <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/jav.02355">lost body mass</a> and abandoned their nests, and some died. Heat stress can also cause <a href="https://www.tandfonline.com/doi/abs/10.1207/s15327604jaws0101_5">abnormal behaviour in pet birds</a> such as <a href="https://www.tandfonline.com/doi/full/10.1080/1828051X.2016.1195711?src=recsys">feather picking</a>, when one bird repeatedly pecks at the feathers of another. In hot weather, regularly check your bird’s cage to make sure it’s clean and stocked with food and water. If the bird is in an outdoor cage or aviary, ensure it is shaded. And a shallow bird bath will help your feathered friend cool off. <h2>Dogs</h2> Dogs and cats can suffer on hot days. That’s especially true if they are: <ul> <li><a href="https://www.ejmanager.com/mnstemps/100/100-1626960667.pdf?t=1657722662">older or overweight</a></li> <li>have thick coats</li> <li>have short snouts/flat faces (which restricts air flow and makes it harder for them to cool down).</li> </ul> Heat stress can cause <a href="https://www.frontiersin.org/articles/10.3389/fvets.2021.742926/full?&utm_source=Email_to_ae_&utm_medium=Email&utm_content=T1_11.5e2_editor&utm_campaign=Email_publication&journalName=Frontiers_in_Veterinary_Science&id=742926">canine hyperthermia</a>, which means the dog’s body temperature becomes dangerously hot. Watch for <a href="https://www.rvc.ac.uk/small-animal-vet/teaching-and-research/fact-files/heatstroke-in-dogs-and-cats#:%7E:text=Early%20signs%20of%20heatstroke%20in%20pet%20animals&text=Panting%2C%20this%20can%20progress%20to,Red%20gums%20or%20tongue">early warning signs</a> of heat stress such as excessive panting and erratic movements. These symptoms can quickly escalate, leading to heat stroke and possible death. <a href="https://pubmed.ncbi.nlm.nih.gov/34828033/">More than 80%</a> of dog owners report exercising their dogs less vigorously, or for shorter periods, during hot weather. That can help avoid heat-related illness. But don’t reduce your dog’s activity levels too much, as that may lead to other health problems. Just time the walks to avoid the heat of the day. Refrain from leaving dogs unattended in vehicles, because they can easily overheat. In fact, it’s better to leave your dog inside home on a hot day, as long as they have a cool place to rest and plenty of water – perhaps even with ice cubes in it. And dogs love to cool off in a kiddie pool or under a sprinkler. If you take your dog out on a hot day, <a href="https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/dogs/health/heat-and-pets#:%7E:text=Be%20aware%20of%20the%20signs,not%20icy%20water%20and%20fanned">carry</a> a container of fresh, cool water for them. And don’t forget to slip-slop-slap: apply a sparing amount of pet sunscreen to your dogs’ exposed pink skin such as ear tips and nose. <h2>Cats</h2> Like other animals, cats can overheat in hot weather. Symptoms include panting heavily, drooling and a rapid pulse. Like with other animals, if you suspect your cat is suffering from heatstroke, call a vet immediately. Climate change and associated heat and floods is likely to aid the spread of parasites and illness <a href="https://www.forbes.com/sites/jeffmcmahon/2022/12/31/guess-whos-loving-climate-change-mosquitos-and-the-pathogens-they-carry/?sh=50654683174a">including</a> tick-borne diseases, <a href="https://pubs.er.usgs.gov/publication/70213352">flea</a> infestations and <a href="https://pubmed.ncbi.nlm.nih.gov/32145530/">heartworm</a>. This puts both cats and dogs at risk. In hot weather, the advice for cat owners is similar to that of dog owners: ensure your cat has plenty of shade and water, and put pet sunscreen on their ear tips and noses, especially if the cat is white. If possible, keep the cat inside during the hottest part of the day. Ensure at least one room is cool and ventilated. And in a heatwave, play with your cat either in the early morning or evening, when the temperature has cooled. <h2>A helping human hand</h2> While humans have the capacity to understand and prepare for climate change, pets will need our help to cope. This includes not just the pets listed above, but others too, including reptiles, guinea pigs and rabbits. As heatwaves and other extreme weather events become more common, the onus is on us to keep our pets safe.<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/210724/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edward-narayan-414899">Edward Narayan</a>, Senior Lecturer in Animal Science, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why is Australia having such a warm winter? A climate expert explains

<a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> If you’ve been out and about the past few days, you may have noticed Australia is experiencing an unseasonably warm winter. It’s been t-shirt weather across many parts of the country’s east, including Sydney where <a href="https://www.theguardian.com/environment/2023/jun/08/australia-ski-season-no-snow-skiing-snowboarding-resorts-closed-warm-weather">temperatures topped 25℃</a> on Sunday. Meanwhile, at high altitudes, the cover at some snowfields remains <a href="https://twitter.com/Cam_Walker/status/1685525535521402880">lacklustre</a>, even after warm conditions forced <a href="https://www.abc.net.au/news/2023-06-09/nsw-resorts-postpone-ski-snowboarding-kings-birthday-lack-snow/102456510">a delay</a> to the start of the traditional ski season. All this comes after the world experienced its hottest month since reliable records began. July brought <a href="https://qz.com/hottest-days-month-ever-recorded-july-2023-1850685494">an incredible 21 of the warmest 30 days</a> ever recorded – prompting the United Nations to declare a new era of “<a href="https://www.theguardian.com/science/2023/jul/27/scientists-july-world-hottest-month-record-climate-temperatures">global boiling</a>”. So what’s going on with the weather in Australia? Should we just enjoy the pleasant conditions, or is it a troubling sign of what’s to come under climate change? <h2>The nice weather, explained</h2> Australia’s unseasonably warm conditions are the result of both natural drivers of our weather and continued global warming. Since early July, warmer and drier conditions have dominated, due to a high pressure system sitting stubbornly over Australia at the moment. The clear conditions are leading to warmer daytime conditions. For example, daytime temperatures in Canberra in July – historically known for its cold winters – were <a href="https://www.9news.com.au/national/canberra-on-track-for-warmest-july-max-temps-on-record/1d0b9683-7dda-4cc0-b6a6-1e32bfa51407">the warmest on record</a>, despite frequent frosty mornings. Sydney has just experienced its <a href="https://www.theguardian.com/australia-news/2023/jul/31/australia-weather-august-warmth-heat-winds-tasmania#:%7E:text=Sydney%27s%2023.5C%20was%20enough,Hill%20goes%20back%20to%201858.">warmest July</a> on record, too. The high pressure has caused the air over the continent’s interior to warm. When cold fronts move across the south of Australia they push this warm air ahead of them, bringing warm and windy conditions to southern coastal areas. This is similar to the weather pattern we see in summer when cities such as Adelaide and Melbourne experience their hottest days. On Thursday, an approaching cold front is forecast to lift temperatures ahead of it to about 23℃ in Adelaide, 20℃ in Melbourne and 18℃ in Hobart. These are very warm temperatures in these locations for early August. And what about the oceans? Around Australia, oceans are a bit cooler than average in some places including <a href="http://www.bom.gov.au/products/IDYOC053.Global.SSTAnomaly.shtml">to the northwest of the continent</a>. But as the image below shows, ocean temperatures are currently above normal in many places around the world, including the west Indian Ocean and the central and eastern tropical Pacific. This indicates a developing El Niño and positive Indian Ocean Dipole – two natural climate drivers that affect Australia’s weather patterns. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=364&fit=crop&dpr=1 600w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=364&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=364&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=458&fit=crop&dpr=1 754w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=458&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/540054/original/file-20230730-191965-434fnd.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=458&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Across most of the world’s oceans, temperatures remain well above normal. National Oceanic and Atmospheric Administration</figcaption></figure> This difference in ocean temperatures reduces the amount of atmospheric moisture over southern and eastern Australia. It also makes low pressure systems weaker and less frequent, reducing rainfall over the region. Over the coming months, warm and dry weather is expected to continue. For the rest of winter and spring, it’s expected to be <a href="http://www.bom.gov.au/climate/outlooks/#/rainfall/summary">drier than normal</a> in the southwest of Western Australia and much of the east of the continent. And the whole of Australia is predicted to be <a href="http://www.bom.gov.au/climate/outlooks/#/temperature/summary">warmer than normal</a> during this period. Of course, this doesn’t rule out occasional cool, wet spells. So is climate change a factor here? Yes. Australia’s land areas have <a href="https://www.ipcc.ch/report/ar6/wg1/downloads/factsheets/IPCC_AR6_WGI_Regional_Fact_Sheet_Australasia.pdf">already warmed by 1.4℃</a> since pre-industrial times. This is the result of humans burning fossil fuels and releasing greenhouse gases. The record winter warmth is part of a <a href="https://theconversation.com/australias-record-breaking-winter-warmth-linked-to-climate-change-83304">long-term upward trend</a> in Australian winter temperatures. As I’ve written <a href="https://theconversation.com/australias-record-breaking-winter-warmth-linked-to-climate-change-83304">previously</a>, there has been at least a 60-fold increase in the likelihood of a very warm winter that can be attributed to human-caused climate change. And we’re likely to see more record warm winters as the planet continues to warm. <h2>Looking north</h2> Of course, Australia’s spell of warm weather seems harmless compared to the Northern Hemisphere’s weird and wild summer. There, simultaneous extreme heatwaves have struck all four continents in recent weeks. Ocean temperatures are well <a href="https://www.washingtonpost.com/weather/2023/07/28/ocean-temperature-maps-heat-records/">above previous record highs</a> for this time of year. Last week, <a href="https://edition.cnn.com/2023/07/25/weather/canadian-wildfire-us-air-pollution/index.html">1,000 wildfires burned</a> in Canada alone. The planet’s warmest average temperatures typically happen in July. That’s because the Northern Hemisphere’s large land masses heat up more quickly than the oceans, in response to the high amounts of radiation from the sun. Still, the heat of the last few weeks has been unprecedented. The heatwaves are <a href="https://theconversation.com/a-climate-expert-explains-the-northern-hemispheres-weird-wild-summer-and-what-it-means-for-australia-209862">linked to</a> high-pressure weather systems that are “blocking” or deflecting oncoming low-pressure systems (and associated clouds and rain). On top of this, human-caused global warming is greatly increasing the chance of record-breaking extreme heat events and concurrent heatwaves across many regions. Worryingly, a <a href="https://www.worldweatherattribution.org/extreme-heat-in-north-america-europe-and-china-in-july-2023-made-much-more-likely-by-climate-change/">rapid analysis</a> by international experts suggests the extreme heat should not be viewed as unusual, given the effects of climate change. For example, it says China’s recent <a href="https://www.smh.com.au/world/asia/china-logs-52-2-celsius-as-extreme-weather-rewrites-records-20230718-p5dp1v.html">record-breaking heatwave</a> should now be expected about once in every five years, on average. Not all extreme weather events can be attributed to human-caused climate change. But the study found climate change significantly contributed to the recent heatwaves in China, North America and Europe. <h2>A sign of what’s to come</h2> The Northern Hemisphere’s heatwaves are very alarming. But Australia’s temperatures are also unusually high for winter – and this is also cause for concern. Warm winters in Australia can negatively affect some parts of the economy, including the ski industry. It also disrupts flora and fauna and increases the chance of “<a href="https://theconversation.com/flash-droughts-can-dry-out-soil-in-weeks-new-research-shows-what-they-look-like-in-australia-161286">flash droughts</a>” – where drier-than-normal conditions turn into severe drought in the space of weeks. The warm, dry conditions may also lead to an <a href="https://www.theguardian.com/cities/2018/aug/15/sydneys-bushfire-season-starts-in-winter-we-may-have-to-rethink-how-we-live">earlier start</a> to the fire season in Australia’s southeast. So while we may appreciate warm winter weather, we mustn’t forget what’s driving it – and how urgently we need to stabilise Earth’s climate by slashing greenhouse gas emissions.<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/210693/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/andrew-king-103126">Andrew King</a>, Senior Lecturer in Climate Science, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"I can’t a fjord it": Inside one of the world’s most extreme restaurants

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 The Menu. Restaurant Iris is located inside a giant silvery orb in Hardangerfjord, the second largest Fjord in Norway. 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. 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. 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. 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". The menu is designed to showcase "the most local ingredients possible", which reflects Madsen's "commitment to sustainability" and her "passion for discovering new ingredients from the ocean". Mari Eriksmoen posted the viral video on TikTok which has racked up over eight million views. "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. She described the experience of walking into the restaurant "like entering a spaceship," and was mesmerised by the "insane views". 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". Another TikTok user compared it to the extraterrestrial spacecraft from the 2016 sci-fi film Arrival. However many other users compared the dining experience to 2022 horror film The Menu, where a group of guests eat at an exclusive restaurant on a remote island and face dire consequences. "Did we learn nothing from The Menu?" commented one user with the crying face emoji. "I know how this movie ends," wrote another user. "I can’t a fjord it," joked a third. 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. "The menu at Iris reads like a story, " a statement said. "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." The tasting menu itself is priced at 3,200 Norwegian Krone ($316) with an optional wine pairing for 2,500 Norwegian Krone ($247). 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).
