The dos and don’ts of caring for your hearing aids

Proper care and maintenance of your hearing aids is important. It will ensure you to get the most out of your aids, prevent problems and maintain optimum hearing conditions. Here are some guidelines to help you care for them. DO: clean your hearing aids regularly with a dry cloth or tissue. DON’T: get your hearing aids wet. That means no wearing them in the shower or when swimming. If they happen to get wet, dry it off immediately. DO: put your hearing aids in their case when you’re not using them DON’T: wear your aids when using aftershave, hairspray, perfume, sunscreen, insect repellent and so on. They contain chemicals that could damage it. Allow time for drying before putting back on hearing aids. DO: use a moisture protection kit/anti-humidity kit. They help with moisture problems (which can affect performance of hearing aids) and extend life of hearing aids. DO: keep out of reach of pets and visiting grandkids. Dogs have been known to chew them up and if swallowed by either pet or grandkid, can be very dangerous. DON’T: expose your device to extreme heats. Don’t leave them in a parked car, near a heater or wear while using a hairdryer. DO: Store your hearing aid in a safe place that's dry and cool. DON’T: leave your hearing aids switched on when you’re not using them. DO: change batteries often so you won’t be stuck with aids that have suddenly run out of power. DON’T: ever insert anything into the sound outlet as it could damage the receiver. If you can’t clean it properly, ask your hearing professional. DO: remove any earwax that gets into your hearing aid. It could cause permanent damage. Image credits: Getty Images

Qantas connects two destinations for the first time in 50 years

Qantas has announced a new international route that will see Aussies connected to a popular holiday destination for the first time in 50 years. Two return flights will operate each week between Sydney and Papua New Guinea's Port Moresby, adding to the service already running to the island nation from Brisbane. “These flights will meet the growing demand from the business community for travel between Australia and Papua New Guinea,” Cam Wallace, CEO of Qantas International and Freight, said. “Our new Sydney service will save customers at least three hours in travel time on return trip by avoiding a stopover in Brisbane.” The route is the latest international service to be added to Qantas’ network out of Sydney, with the airline suggesting it will support both business and trade between Australia and Papua New Guinea. Trailing behind island nations such as Fiji and Indonesia, Papua New Guinea's tourism industry is steadily growing in popularity largely due to containing the world’s third largest rainforest, crystal clear waters, and 45,000km of coral reefs. As the number of annual travellers to PNG increases, so does accommodation options, with Marriott International announcing earlier this year that they would be expanding their accommodation into Papua New Guinea, marketing those wishing to have an “extended stay”. “We are thrilled to establish our inaugural foothold in Papua New Guinea with this milestone opening”, said Sean Hunt, area vice-president of Australia, New Zealand and Pacific for Marriott International, in a statement. “This is also a debut for the Marriott Executive Apartments brand in the region, allowing us to diversify our offering to cater to ambitious and adventurous travellers who seek a premium, trusted extended-stay experience.” While the new tourism initiatives have been put in place to help boost the economy of PNG, Papua New Guinea currently has travel advisory warnings in place, with SmartTraveller urging visitors to “exercise a high degree of caution in Papua New Guinea overall due to high levels of serious crime, with “higher levels” applying in some areas.

Police officer sought in connection to disappearance of two men

A NSW police officer is sought in connection to the suspicious disappearance of two men, who haven't been heard from since Monday. Former Studio 10 host Jesse Baird and his boyfriend Luke Davies were last seen four days ago, with police launching an investigation into their disappearance. A number of their personal items, including a watch, clothes, credit cards and keys were found by a worker in Club Cronulla, with blood stains present on the items. Police have also searched two homes during their investigation - one in Balmain and one in Paddington - with officers "immediately" establishing a crime scene at the Paddington home after finding blood spatters. According to officers, a “significant” amount of blood consistent with a fatality and signs of a struggle were discovered inside Mr Baird’s Paddington home on Thursday afternoon. More personal items belonging to the couple were recovered from a skip bin 20 kilometres from the home in question. Police have called for Constable Beau Lamarre to come forward as part of their investigation, who is the ex-boyfriend of one of the men. Friends of Baird have revealed he previously expressed concerns he was being stalked by another man. Police confirmed on Thursday they wanted to speak to Constable Lamarre in relation to the case and were desperately trying to reach him. "Following inquiries, detectives are looking at a line of inquiry that a third person may be able to assist with the investigation," NSW Police said, in a statement. "Police are currently trying to locate him." Police have not said that the officer was involved in the disappearance, only that they would like to speak to him, as no arrest warrant has been issued.

"I want answers": Simon Dorante-Day's cunning plan to prove royal connections

The Queensland man claiming to be the son of King Charles and Queen Camilla has shared his new plan to prove once and for all that he has royal family connections. Simon Dorante-Day has long claimed through his 30 years of research, he discovered that he is the illegitimate son of the monarch, and has attempted to prove his theory through various means. Now, his new plan to get his hands on royal DNA to unequivocally prove his family heritage involves another member of the royal family. Speaking with <a href="https://7news.com.au/lifestyle/aussie-man-claiming-to-be-charles-son-drops-new-prince-harry-dna-bombshell-c-13488374" target="_blank" rel="noopener">7News</a>, the 57-year-old said he and his wife have been told by a “trusted source” that Prince Harry could be amenable to helping them gather proof. “We got advice from a really good, really trusted source that we should approach Harry and make a connection there and ask for DNA,” Elvianna said. Simon added, “I was really taken aback when he said that. But it’s definitely something I’m going to do. I’ve long been a supporter of Harry and Meghan, I think it’s disgraceful the way they’ve been treated by the royal family." “The way they are treated on social media too, it’s just one big ‘Punch-Meghan-and-Harry-a-thon’, seriously. It’s really starting to annoy me." He said he is planning to "make contact with him and explore this as an opportunity," pointing out that the royal family's treatment of Harry could make him more willing to help. "At the end of the day, I feel like he just might be as keen as I am to expose what Charles and Camilla and the powers that be have done to me. The injustice." “It’s worth me pointing out that Charles and Camilla, Buckingham Palace, the entire royal family - not one of them has ever said my claims are not true. They’ve never denied what I believe, told me I’m wrong." Simon said “the wheels are in motion” in terms of making contact with Prince Harry, and that he’s hopeful of a positive outcome. “I want answers,” he said. “And I feel Prince Harry is the man to help me find them.” “And I think their silence speaks volumes.” Simon said “the wheels are in motion” in terms of making contact with Prince Harry, and that he’s hopeful of a positive outcome. “I want answers,” he said. “And I feel Prince Harry is the man to help me find them.” Image credits: Facebook / Getty Images

New global appeal launched for one of Australia's most wanted men

Police have ramped up their efforts to locate one of Australia's most wanted men, who they believe fled the country over two decades ago. In 1999, James Dalamangas allegedly fled to Greece after his believed involvement in the death of a Sydney father. George Giannopoulos attended a Belmore nightclub in Sydney’s south west on April 25th 1999 when he was stabbed twice and died while trying to intervene in a fight between two patrons. A warrant was issued for Mr Dalamangas' arrest the next day over his alleged involvement in the brutal murder, although he was never found. Dalamangas, who worked as a bouncer, is also wanted for questioning over the 1997 shooting murder of another Kings Cross bouncer Tim Voukelates. He was also involved in a brawl at Star City Casino where his brother Peter was killed in 1998. Police believe he fled the country after Mr Giannopoulos' death, with authorities believing he is still living in Greece. After attempts to extradite Mr Dalamangas from Greece were not successful in 2003, Greek authorities agreed to commence the prosecution of Mr Dalamangas over his alleged role in the murder, but the process was suspended in 2007 when he couldn't be found. As the 25-year-long Greek statute of limitations nears, police are re-appealing for anyone with information to come forward, particularly if they can assist in locating Mr Dalamangas in Greece. “A warrant was issued for Mr Dalamangas’ arrest; however, despite extensive inquiries, he has never been located,” police said in a statement. Detectives have released an age progression photo of Dalamangas, who would now be aged 53. Dalamangas is Mediterranean in appearance, between 180 and 185cm tall with a medium build, dark hair and brown eyes. Image credits: AFP

"Do you hear it?": Worldwide hum global mystery baffles scientists

A perplexing phenomenon known as "The Worldwide Hum" has been capturing the attention of scientists and citizens alike, as an unusual low-frequency noise continues to puzzle experts. This mysterious hum, first recorded in 2012, has been reported by thousands of people worldwide, sparking investigations, online discussions and even <a href="https://www.thehum.info/" target="_blank" rel="noopener">the creation of an interactive map</a> documenting instances of the enigmatic sound. As researchers strive to unravel the mystery, individuals share their experiences, raising questions about its origin and effects. Described as a low rumbling or droning sound, "the hum" is often likened to the idling of a car or truck engine. What makes this phenomenon particularly intriguing is that it is not universally heard, with reports of the hum being exclusive to certain individuals. Some claim it is more pronounced at night than during the day, and louder indoors than outdoors. One Reddit user even compared it to the low-frequency vibrations felt when a passenger jet flies overhead. Since its first documentation, more than 6,500 instances of the hum have been reported globally, with new cases continually emerging. The interactive user-generated World Hum Map and Database Project captures the experiences of those who have encountered the sound, providing a comprehensive overview of its widespread occurrence. In some regions, authorities such as the Environment Protection Authority (EPA) have conducted investigations, as was the case in the NSW Waverley Council ten years ago. Despite these efforts, the source of the hum remains elusive. Individuals affected by the mysterious noise often find solace in online communities, where they share their experiences and discuss possible explanations. Some describe feeling as though they are "going insane", and say that the psychological impact of the persistent hum is actually very severe. Facebook support groups have become a platform for individuals to connect, share anecdotes and speculate about the origin of the sound. Theories range from the mundane – such as the use of headphones causing collective tinnitus – to more complex environmental factors. While tinnitus, a symptom of auditory system issues, has been proposed as a potential explanation, it does not account for the collective experience of the hum. Various theories, including industrial plants, ocean waves, lightning strikes and the proliferation of mobile phone towers, have been suggested over the years. However, none of these explanations have gained widespread acceptance or provided a conclusive answer. Dr Glen MacPherson, who initiated the World Hum Map and Database Project, experienced the hum firsthand on Canada's Sunshine Coast. Having debunked the idea of "hum hotspots", Dr MacPherson theorises that the hum may be a subjective phenomenon, akin to tinnitus, originating from within the individual rather than an external source. His 11 years of research highlight the complexity of the mystery, challenging initial assumptions and pointing towards the need for further investigation. As "The Worldwide Hum" continues to captivate the curiosity of scientists and citizens worldwide, the quest for understanding remains elusive. While theories abound, the true origin of the hum remains unknown, leaving both experts and individuals alike intrigued by a phenomenon that transcends geographic boundaries and defies conventional explanations.

Embracing friendships in adulthood: A guide to making meaningful connections

Navigating the landscape of friendship in adulthood might initially appear daunting, but the profound impact that it can have on our mental well-being is huge. Not only do friendships foster a sense of camaraderie, but they nurture feelings of belonging and acceptance. Important at every life stage, it’s not uncommon to encounter challenges in building new friendships as we age and embark on differing paths. However, Jacqui Manning, Resident Psychologist at Connected Women, a female-driven organisation dedicated to cultivating friendships for women over 50, is here to impart her invaluable tips and tricks, paving the way for a friend-finding journey that unfolds with ease and fulfilment. “Forming new friendships in adulthood may take a little more time and effort, but it doesn’t have to be scary,” Jacqui explains. “Approaching the prospect of making a friend with genuine curiosity and a shared interest can transform the experience into an exciting journey rather than a daunting task. Focus on common ground, be open-minded, and embrace the adventure of getting to know someone new. By emphasising shared interests and creating a comfortable, judgment-free space, the process of making a friend becomes a welcoming exploration rather than an intimidating challenge." Stay Open It can be a slippery slope once we let our thoughts spiral into the possibility of rejection. Instead of worrying, why not consider all the opportunities to grow a connection? Jacqui explains, “As we age, the energy we have to make friends can dwindle, making it natural to withdraw into the comfort of our own shell. However, the need for connection is as strong as ever. This serves as an important reminder to be open. Deeper connections won’t have the chance to form if we keep one another at arm’s length so engage in conversations about hobbies and discuss any goals or anxieties openly, as it is through this openness that a profound connection is likely to be forged. Find Your Community Finding a group of new friends could be as simple as enjoying your favourite pastime. Like attracts like, and finding a like-minded group who share similar interests could be the key to unlocking more meaningful relationships. “Whether it’s joining a book club, cooking class, yoga, or bonding over a game of cards, whatever your passion may be, start by kicking off a conversation with someone who participates in a shared activity. While exploring a new hobby is fantastic, consider turning your attention closer to home and connecting with those who already share your interests,” Jacqui adds. Take Note Long-lasting friendships can fill gaps in our life we never knew existed. As Jacqui explains, “Take note of how supported you currently feel and if there are any areas that may need a little nudge. Reflection will invariably help to narrow down the type of friendship you may be seeking and allow you to better understand your own needs. Through self-reflection, you gain invaluable insights that not only pinpoint the specific type of friendship you might be yearning for but also enhance your understanding of your own emotional requirements. This conscious exploration becomes a compass, guiding you toward the relationships that can truly fulfil and enrich your life.” The journey of making friendships in adulthood is not without its challenges, but the rewards are immeasurable. As Jacqui reminds us, being open to new connections, actively engaging in shared interests, and conducting self-reflection are key elements in fostering meaningful relationships. “The path to forming long-lasting bonds involves stepping out of our comfort zones, whether by joining a new group, pursuing shared activities, or simply initiating conversations. Remember, the richness of these connections lies not just in the joy of shared experiences but also in the support and understanding they provide,” Jacqui concludes, Friendships in adulthood are well worth investing in, providing fulfilment, support, and the delight of shared moments. So, embrace the adventure, take note of your needs, and savour the delight of building connections that truly enrich your life. Ready to try your hand at building new friendships?

Will we still have antibiotics in 50 years? We asked 7 global experts

Almost since antibiotics were <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2937522/#:%7E:text=Since%20the%20introduction%20in%201937,operate%20some%2070%20years%20later.">first discovered</a>, we’ve been aware bacteria can learn how to overcome these medicines, a phenomenon known as antimicrobial resistance. The World Health Organization says we’re currently <a href="https://www.who.int/news/item/20-09-2017-the-world-is-running-out-of-antibiotics-who-report-confirms">losing to the bugs</a>, with resistance increasing and too few new antibiotics in the pipeline. We wanted to know whether experts around the world think we will still have effective antibiotics in 50 years. Seven out of seven experts said yes. Lori Burrows - Biochemist, Canada Yes! Antibiotics are a crucial component of modern medicine, and we can't afford to lose them. Despite the rise of resistance in important pathogens (bugs), and the substantial decrease in new drugs in development, we have multiple tools at our disposal to protect antibiotics. Stewardship - the principle of using antibiotics only when absolutely necessary - is key to maintaining the usefulness of current antibiotics and preventing resistance to new drugs from arising. New diagnostics, such as the rapid tests that became widely available during the pandemic, can inform stewardship efforts, reducing inappropriate antibiotic use for viral diseases. Finally, researchers continue to find creative ways, including the use of powerful artificial intelligence approaches, to identify antimicrobial compounds with new targets or new modes of action. Other promising tactics include using viruses that naturally kill bacteria, stimulating the host's immune system to fight the bacteria, or combining existing antibiotics with molecules that can enhance antibiotic activity by, for example, increasing uptake or blocking resistance. André Hudson - Biochemist, United States Yes. The real question is not whether we will have antibiotics 50 years from now, but what form of antibiotics will be used. Most antibiotics we use today are modelled after natural products isolated from organisms such as fungi and plants. The use of <a href="https://news.mit.edu/2020/artificial-intelligence-identifies-new-antibiotic-0220">AI</a>, machine learning, and other <a href="https://www.theguardian.com/technology/2023/may/25/artificial-intelligence-antibiotic-deadly-superbug-hospital">computational tools</a> to help design novel, unnatural compounds that can circumvent the evolution of antibiotic resistance are only in the very early stages of development. Many of the traditional medicines such as penicillins and other common antibiotics of today which are already waning in efficacy, will probably be of very little use in 50 years. Over time, with the aid of new technology, I predict we will have new medicines to fight bacterial infections. Ray Robins-Browne - Microbiologist, Australia Yes, we will have antibiotics (by which I mean antimicrobial drugs), because people will still get infections despite advances in immunisation and other forms of prevention. Having said this, drugs of the future will be quite different from those we use today, which will have become obsolete well within the next 50 years. The new drugs will have a narrow spectrum, meaning they will be targeted directly at the specific cause of the infection, which we will determine by using rapid, point-of-care diagnostic tests, similar to the RATS we currently use to diagnose COVID. Antimicrobials of the future won’t kill bacteria or limit their growth, because this encourages the development of resistance. Instead, they will limit the ability of the bacteria to cause disease or evade our immune systems. Raúl Rivas González - Microbiologist, Spain Yes, but not without effort. Currently, antimicrobial resistance is a leading cause of death globally, and will continue to rise. But in my opinion, there will still be useful antibiotics to combat bacterial infections within 50 years. To achieve this, innovation and investment is required. Artificial intelligence may even be able to help. An example is the compound "RS102895", which eliminates the multi-resistant superbug Acinetobacter baumannii. This was identified through a machine learning algorithm. The future of antibiotics requires substantial changes in the search for new active molecules and in the design of therapies that can eliminate bacteria without developing resistance. We are on the right path. An example is the discovery of clovibactin, recently isolated from uncultured soil bacteria. Clovibactin effectively kills antibiotic-resistant gram-positive bacteria without generating detectable resistance. Future antimicrobial therapy may consist of new antibiotics, viruses that kill bacteria, specific antibodies, drugs that counter antibiotic resistance, and other new technology. Fidelma Fitzpatrick - Microbiologist, United Kingdom Yes, but not many. Without rapid scale-up of measures to curtail the "<a href="https://www.oecd.org/health/embracing-a-one-health-framework-to-fight-antimicrobial-resistance-ce44c755-en.htm">alarming global health threat</a>" of antimicrobial resistance by 2073, there will be few effective antibiotics left to treat sepsis. The <a href="https://www.cdc.gov/drugresistance/covid19.html">Centre for Disease Control</a> has indicated a reversal of progress following the pandemic, when all focus in healthcare, government and society was on COVID. Without an approach targeting people, animals, agri-food systems and the environment, antimicrobial resistance will continue its upward trajectory. <a href="https://www.worldbank.org/en/topic/health/publication/drug-resistant-infections-a-threat-to-our-economic-future">Doing nothing</a> is unacceptable – lives will be lost, healthcare expenditure will increase and workforce productivity will suffer. The highest burden of antimicrobial resistance is in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02724-0/fulltext">low-income countries</a>. <a href="https://www.ncbi.nlm.nih.gov/books/NBK543407/">Action plans</a> exist in most OECD, European and G20 countries. In all countries plans need to be funded and implemented across all relevant sectors as above. Better integrated data to track antibiotic use and resistance across human and animal health and the environment, in addition to research and development for new antibiotics, vaccines and diagnostics, will be necessary. Juliana Côrrea - Public health expert, Brazil Yes. However, <a href="https://www.sciencedirect.com/science/article/pii/S0188440905002730?via%3Dihub">available data</a> suggest that without a shift in the political agenda towards the control and prevention of antimicrobial resistance, several antibiotics will have lost their utility. The problem of bacterial resistance is not new and the risk of antibiotics becoming ineffective in the face of the evolutionary capacity of bacteria is one of the main problems facing global health. The creation of policies to promote the appropriate use of this resource has not progressed at the same speed as inappropriate use in human and animal health and in agricultural production. The factors that impact antibiotic use are complex and vary according to local contexts. The response to the problem goes far beyond controlling use at the individual level. We must recognise the social, political, and economic dimensions in proposing more effective governance. Yori Yuliandra - Pharmacist, Indonesia Yes. Despite their <a href="https://www.who.int/news-room/fact-sheets/detail/antimicrobial-resistance">reduced efficacy over time</a>, antibiotics continue to be produced every year. Researchers are tirelessly working to develop new and more effective antibiotics. And researchers are actively exploring combinations of antibiotics to enhance their efficacy. While antimicrobial resistance is rising, researchers have been making remarkable progress in addressing this issue. They have developed innovative antibiotic classes such as <a href="https://doi.org/10.4155/fmc-2016-0041">FtsZ inhibitors</a> which can inhibit cell division, a process necessary for bacteria to multiply. <a href="https://www.who.int/publications/i/item/9789240021303">Clinical trials</a> are currently taking place. A deeper understanding of the molecular aspects of bacterial resistance has led to the discovery of new treatment strategies, such as the <a href="https://doi.org/10.1039/D2MD00263A">inhibition of key enzymes</a> that play a pivotal role in bugs becoming resistant. And <a href="https://doi.org/10.1038/s42003-021-02586-0">advances in computer technology</a> have greatly accelerated drug discovery and development efforts, offering hope for the rapid discovery of new antibiotics and treatment strategies.

6 reasons why global temperatures are spiking right now

<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> The world is very warm right now. We’re not only seeing record temperatures, but the records are being broken by record-wide margins. Take the preliminary September global-average temperature anomaly of 1.7°C above pre-industrial levels, for example. It’s an incredible 0.5°C above the previous record. So why is the world so incredibly hot right now? And what does it mean for keeping our Paris Agreement targets? Here are six contributing factors – with climate change the main reason temperatures are so high. <h2>1. El Niño</h2> One reason for the exceptional heat is we are in a <a href="http://www.bom.gov.au/climate/enso/#tabs=Pacific-Ocean">significant El Niño</a> that is still strengthening. During El Niño we see warming of the surface ocean over much of the tropical Pacific. This warming, and the effects of El Niño in other parts of the world, raises global average temperatures by <a href="https://www.realclimate.org/index.php/archives/2023/01/2022-updates-to-the-temperature-records/">about 0.1 to 0.2°C</a>. Taking into account the fact we’ve just come out of a triple La Niña, which cools global average temperatures slightly, and the fact this is the first major El Niño in eight years, it’s not too surprising we’re seeing unusually high temperatures at the moment. Still, El Niño alone isn’t enough to explain the crazily high temperatures the world is experiencing. <h2>2. Falling pollution</h2> Air pollution from human activities cools the planet and has offset some of the warming caused by humanity’s greenhouse gas emissions. There have been efforts to reduce this pollution – since 2020 there has been an <a href="https://sdg.iisd.org/news/imo-advances-measures-to-reduce-emissions-from-international-shipping/">international agreement</a> to reduce sulphur dioxide emissions from the global shipping industry. It has been speculated this cleaner air has contributed to the recent heat, particularly over the record-warm <a href="https://climate.copernicus.eu/record-breaking-north-atlantic-ocean-temperatures-contribute-extreme-marine-heatwaves">north Atlantic</a> and Pacific regions with high shipping traffic. It’s likely this is contributing to the extreme high global temperatures – but only on the order of hundredths of a degree. <a href="https://www.carbonbrief.org/analysis-how-low-sulphur-shipping-rules-are-affecting-global-warming/">Recent analysis</a> suggests the effect of the 2020 shipping agreement is about an extra 0.05°C warming by 2050. <h2>3. Increasing solar activity</h2> While falling pollution levels mean more of the Sun’s energy reaches Earth’s surface, the amount of the energy the Sun emits is itself variable. There are different solar cycles, but an 11-year cycle is the most relevant one to today’s climate. The Sun is becoming <a href="https://edition.cnn.com/2023/07/14/world/solar-maximum-activity-2024-scn/index.html">more active</a> from a minimum in late 2019. This is also contributing a small amount to the spike in global temperatures. Overall, increasing solar activity is contributing only hundredths of a degree at most to the recent global heat. <h2>4. Water vapour from Hunga Tonga eruption</h2> On January 15 2022 the underwater <a href="https://www.jpl.nasa.gov/images/pia26006-hunga-tonga-hunga-haapai-eruption">Hunga Tonga–Hunga Haʻapai volcano erupted</a> in the South Pacific Ocean, sending large amounts of water vapour high up into the upper atmosphere. Water vapour is a greenhouse gas, so increasing its concentration in the atmosphere in this way does intensify the greenhouse effect. Even though the eruption happened almost two years ago, it’s still having a small warming effect on the planet. However, as with the reduced pollution and increasing solar activity, we’re talking about hundredths of a degree. <figure><iframe src="https://www.youtube.com/embed/6oANPi-SWN0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>5. Bad luck</h2> We see variability in global temperatures from one year to the next even without factors like El Niño or major changes in pollution. Part of the reason this September was so extreme was likely due to weather systems being in the right place to heat the land surface. When we have persistent high-pressure systems over land regions, as seen recently over places like <a href="https://www.theguardian.com/environment/2023/oct/01/autumn-heat-continues-in-europe-after-record-breaking-september">western Europe</a> and <a href="https://www.abc.net.au/news/2023-09-19/australia-weather-september-heat-records-tumble/102870294">Australia</a>, we see local temperatures rise and the conditions for unseasonable heat. As water requires more energy to warm and the ocean moves around, we don’t see the same quick response in temperatures over the seas when we have high-pressure systems. The positioning of weather systems warming up many land areas coupled with persistent ocean heat is likely a contributor to the global-average heat too. <h2>6. Climate change</h2> By far the biggest contributor to the overall +1.7°C global temperature anomaly is human-caused climate change. Overall, humanity’s effect on the climate has been a global warming of <a href="https://www.globalwarmingindex.org/">about 1.2°C</a>. The record-high rate of greenhouse gas emissions means we should expect global warming to accelerate too. While humanity’s greenhouse gas emissions explain the trend seen in September temperatures over many decades, they don’t really explain the big difference from last September (when the greenhouse effect was almost as strong as it is today) and September 2023. Much of the difference between this year and last comes back to the switch from La Niña to El Niño, and the right weather systems in the right place at the right time. <h2>The upshot: we need to accelerate climate action</h2> September 2023 shows that with a combination of climate change and other factors aligning we can see alarmingly high temperatures. These anomalies may appear to be above the 1.5°C global warming level referred to in the Paris Agreement, but that’s about keeping <a href="https://climateanalytics.org/briefings/understanding-the-paris-agreements-long-term-temperature-goal/">long-term global warming</a> to low levels and not individual months of heat. But we are seeing the effects of climate change unfolding more and more clearly. The most vulnerable are suffering the biggest impacts as wealthier nations continue to emit the largest proportion of greenhouse gases. Humanity must accelerate the path to net zero to prevent more record-shattering global temperatures and damaging extreme events.<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/215140/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.

Does running water really trigger the urge to pee? Experts explain the brain-bladder connection

<a href="https://theconversation.com/profiles/james-overs-1458017">James Overs</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a>; <a href="https://theconversation.com/profiles/david-homewood-1458022">David Homewood</a>, <a href="https://theconversation.com/institutions/melbourne-health-950">Melbourne Health</a>; <a href="https://theconversation.com/profiles/helen-elizabeth-oconnell-ao-1458226">Helen Elizabeth O'Connell AO</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>, and <a href="https://theconversation.com/profiles/simon-robert-knowles-706104">Simon Robert Knowles</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> We all know that feeling when nature calls – but what’s far less understood is the psychology behind it. Why, for example, do we get the urge to pee just before getting into the shower, or when we’re swimming? What brings on those “nervous wees” right before a date? Research suggests our brain and bladder are in constant communication with each other via a neural network called the <a href="https://www.einj.org/journal/view.php?doi=10.5213/inj.2346036.018">brain-bladder axis</a>. This complex web of circuitry is comprised of sensory neural activity, including the sympathetic and parasympathetic nervous systems. These neural connections allow information to be sent <a href="https://doi.org/10.3390/diagnostics12123119">back and forth</a> between the brain and bladder. The brain-bladder axis not only facilitates the act of peeing, but is also responsible for telling us we need to go in the first place. <h2>How do we know when we need to go?</h2> As the bladder fills with urine and expands, this activates special receptors detecting stretch in the nerve-rich lining of the bladder wall. This information is then relayed to the “periaqueductal gray” – a part of the brain in the brainstem which <a href="https://www.nature.com/articles/nrn2401">constantly monitors</a> the bladder’s filling status. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=454&fit=crop&dpr=1 600w, https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=454&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=454&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=570&fit=crop&dpr=1 754w, https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=570&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/547931/original/file-20230913-19-2kgkhk.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=570&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>The periaqueductal gray is a section of gray matter located in the midbrain section of the brainstem. <a class="source" href="https://en.wikipedia.org/wiki/Brainstem#/media/File:1311_Brain_Stem.jpg">Wikimedia/OpenStax</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></figcaption></figure> Once the bladder reaches a certain threshold (roughly 250-300ml of urine), another part of the brain called the “pontine micturition centre” is activated and signals that the bladder needs to be emptied. We, in turn, <a href="https://pubmed.ncbi.nlm.nih.gov/16254993/">register this</a> as that all-too-familiar feeling of fullness and pressure down below. Beyond this, however, a range of situations can trigger or exacerbate our need to pee, by increasing the production of urine and/or stimulating reflexes in the bladder. <h2>Peeing in the shower</h2> If you’ve ever felt the need to pee while in the shower (no judgement here) it may be due to the sight and sound of running water. In a 2015 study, <a href="https://doi.org/10.1371/journal.pone.0126798">researchers demonstrated</a> that males with urinary difficulties found it easier to initiate peeing when listening to the sound of running water being played on a smartphone. Symptoms of overactive bladder, including urgency (a sudden need to pee), have also been <a href="https://www.alliedacademies.org/articles/environmental-cues-to-urgency-and-incontinence-episodes-in-chinesepatients-with-overactive-urinary-bladder-syndrome.html">linked to</a> a range of environmental cues involving running water, including washing your hands and taking a shower. This is likely due to both physiology and psychology. Firstly, the sound of running water may have a relaxing physiological effect, increasing activity of the parasympathetic nervous system. This would relax the bladder muscles and prepare the bladder for emptying. At the same time, the sound of running water may also have a conditioned psychological effect. Due to the countless times in our lives where this sound has coincided with the actual act of peeing, it may trigger an instinctive reaction in us to urinate. This would happen in the same way <a href="https://www.simplypsychology.org/pavlov.html">Pavlov’s dog learnt</a>, through repeated pairing, to salivate when a bell was rung. <h2>Cheeky wee in the sea</h2> But it’s not just the sight or sound of running water that makes us want to pee. Immersion in cold water has been shown to cause a “cold shock response”, <a href="https://pubmed.ncbi.nlm.nih.gov/19945970">which activates</a> the sympathetic nervous system. This so-called “fight or flight” response drives up our blood pressure which, in turn, causes our kidneys to filter out more fluid from the bloodstream to stabilise our blood pressure, in a process called “<a href="https://link.springer.com/article/10.1007/BF00864230">immersion diuresis</a>”. When this happens, our bladder fills up faster than normal, triggering the urge to pee. Interestingly, immersion in very warm water (such as a relaxing bath) may also increase urine production. In this case, however, it’s due to activation of the parasympathetic nervous system. <a href="https://doi.org/10.1007/s004210050065">One study</a> demonstrated an increase in water temperature from 40℃ to 50℃ reduced the time it took for participants to start urinating. Similar to the effect of hearing running water, the authors of the study suggest being in warm water is calming for the body and activates the parasympathetic nervous system. This activation can result in the relaxation of the bladder and possibly the pelvic floor muscles, bringing on the urge to pee. <h2>The nervous wee</h2> We know stress and anxiety can cause bouts of nausea and butterflies in the tummy, but what about the bladder? Why do we feel a sudden and frequent urge to urinate at times of heightened stress, such as before a date or job interview? When a person becomes stressed or anxious, the body goes into fight-or-flight mode through the activation of the sympathetic nervous system. This triggers a cascade of physiological changes designed to prepare the body to face a perceived threat. As part of this response, the muscles surrounding the bladder may contract, leading to a more urgent and frequent need to pee. Also, as is the case during immersion diuresis, the increase in blood pressure associated with the stress response may <a href="https://doi.org/10.1172/JCI102496">stimulate</a> the kidneys to produce more urine. <h2>Some final thoughts</h2> We all pee (most of us several times a day). Yet <a href="https://doi.org/10.5489/cuaj.1150">research has shown</a> about 75% of adults know little about how this process actually works – and even less about the brain-bladdder axis and its role in urination. <a href="https://www.continence.org.au/about-us/our-work/key-statistics-incontinence#:%7E:text=Urinary%20incontinence%20affects%20up%20to,38%25%20of%20Australian%20women1.">Most Australians</a> will experience urinary difficulties at some point in their lives, so if you ever have concerns about your urinary health, it’s extremely important to consult a healthcare professional. And should you ever find yourself unable to pee, perhaps the sight or sound of running water, a relaxing bath or a nice swim will help with getting that stream to flow.<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/210808/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/james-overs-1458017">James Overs</a>, Research Assistant, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a>; <a href="https://theconversation.com/profiles/david-homewood-1458022">David Homewood</a>, Urology Research Registrar, Western Health, <a href="https://theconversation.com/institutions/melbourne-health-950">Melbourne Health</a>; <a href="https://theconversation.com/profiles/helen-elizabeth-oconnell-ao-1458226">Helen Elizabeth O'Connell AO</a>, Professor, University of Melbourne, Department of Surgery.

Research reveals who’s been hit hardest by global warming in their lifetime - and the answer may surprise you

We’ve seen it in the past few weeks as temperatures hit record highs around the world – both in the Northern Hemisphere and the <a href="https://theconversation.com/why-is-australia-having-such-a-warm-winter-a-climate-expert-explains-210693">warm Australian winter</a>. Global warming is caused by humanity’s greenhouse gas emissions, which continue at <a href="https://theconversation.com/global-carbon-emissions-at-record-levels-with-no-signs-of-shrinking-new-data-shows-humanity-has-a-monumental-task-ahead-193108">near-record pace</a>. These emissions are predominantly generated by people in the world’s wealthiest regions. Our world-first analysis, <a href="https://iopscience.iop.org/article/10.1088/2752-5295/aceff2">published today</a>, examines the experience of global warming over the lifetimes of people around the world: young and old, rich and poor. We sought to identify who has perceived warmer temperatures most keenly. We found middle-aged people in equatorial regions have lived through the most perceptible warming in their lifetimes. But many young people in lower-income countries could experience unrecognisable changes in their local climate later in life, unless the world rapidly tackles climate change. <h2>Measuring the climate change experience</h2> We examined temperature data and population demographics information from around the world. Key to our analysis was the fact that not all warming is due to human activity. Some of it is caused by natural, year-to-year variations in Earth’s climate. These natural ups and downs are due to a number of factors. They include variations in the energy Earth receives from the sun, the effects of volcanic eruptions, and transfers of heat between the atmosphere and the ocean. This variability is stronger in mid-to-high-latitude parts of the world (those further from the equator) than in low-latitude areas (in equatorial regions). That’s because the weather systems further away from the equator draw in hot or cold air from neighbouring areas, but equatorial areas don’t receive cold air at all. That’s why, for example, the annual average temperature in New York is naturally more variable than in the city of Kinshasa (in the Democratic Republic of Congo). To account for this, we applied what’s known as the “<a href="https://archive.ipcc.ch/ipccreports/tar/wg1/346.htm#:%7E:text=The%20%EF%BF%BDsignal%20to%20noise,to%20this%20natural%20variability%20noise.">signal-to-noise ratio</a>” at each location we studied. That allowed us to separate the strength of the climate change “signal” from the “noise” of natural variability. Making this distinction is important. The less naturally variable the temperature, the clearer the effects of warming. So warming in Kinshasa over the past 50 years has been much more perceptible than in New York. Our study examined two central questions. First, we wanted to know, for every location in the world, how clearly global warming could be perceived, relative to natural temperature variability. Second, we wanted to know where this perceived change was most clear over human lifetimes. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.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/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=394&fit=crop&dpr=1 600w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=394&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=394&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=495&fit=crop&dpr=1 754w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=495&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/541474/original/file-20230807-17-ogjdti.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=495&fit=crop&dpr=3 2262w" alt="Annual-average temperatures at four major cities with signal-to-noise ratios shown for 20, 50 and 80 years up to 2021." /></a><figcaption>Annual-average temperatures at four major cities with signal-to-noise ratios shown for 20, 50 and 80 years up to 2021. Author provided</figcaption></figure> <h2>Our results</h2> So what did we find? As expected, the most perceptible warming is found in tropical regions – those near the equator. This includes developing parts of the world that constitute the Global South – such as Africa, Latin America and the Caribbean, and Asia. Household incomes in the Global South are typically lower than in industrialised nations (known as the Global North). We might, then, conclude people in the poorest parts of the world have experienced the most perceptible global warming over their lifetimes. But that’s not always the case. Why? Because most parts of the Global South have younger populations than wealthier regions. And some people under the age of 20, including in northern India and parts of Sub-Saharan Africa, haven’t experienced warming over their lifetimes. In these places, the lack of recent warming is likely down to a few factors: natural climate variability, and the local cooling effect of particles released into the atmosphere from <a href="https://iopscience.iop.org/article/10.1088/1748-9326/ac3b7a">pollution</a> and changes in land use. There’s another complication. Some populated regions of the world also experienced slight cooling in the mid-20th century, primarily driven by human-caused <a href="https://www.nature.com/articles/nature10946">aerosol emissions</a>. So, many people born earlier than the 1950s have experienced less perceptible warming in their local area than those born in the 1960s and 1970s. This may seem counter-intuitive. But a cooling trend in the first few decades of one’s life means the warming experienced over an entire lifespan (from birth until today) is smaller and less detectable. So what does all this mean? People in equatorial areas born in the 1960s and 1970s – now aged between about 45 and 65 – have experienced more perceptible warming than anyone else on Earth. <h2>Rich countries must act</h2> Our findings are important, for several reasons. Identifying who has experienced significant global warming in their lives may help explain <a href="https://www.nature.com/articles/nclimate2660">attitudes to tackling climate change</a>. Our findings also raise significant issues of fairness and equity. Humanity will continue to warm the planet until we reach global net-zero emissions. This means many young people in lower-income countries may, later in life, experience a local climate that is unrecognisable to that of their youth. Of course, warming temperatures are not the only way people experience climate change. Others include sea-level rise, more intense drought and rainfall extremes. We know many of these impacts are felt most acutely by <a href="https://www.aljazeera.com/opinions/2022/5/11/climate-change-is-devastating-the-global-south">the most vulnerable populations</a>. Cumulative greenhouse gas emissions are much higher in the Global North, due to economic development. To address this inequality, rich industrialised nations must take a leading role in reducing emissions to net-zero, and helping vulnerable countries adapt to climate change.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/211108/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>; <a href="https://theconversation.com/profiles/ed-hawkins-104793">Ed Hawkins</a>, Professor of Climate Science, <a href="https://theconversation.com/institutions/university-of-reading-902">University of Reading</a>; <a href="https://theconversation.com/profiles/hunter-douglas-1460792">Hunter Douglas</a>, PhD Candidate, <a href="https://theconversation.com/institutions/te-herenga-waka-victoria-university-of-wellington-1200">Te Herenga Waka — Victoria University of Wellington</a>, and <a href="https://theconversation.com/profiles/luke-harrington-489028">Luke Harrington</a>, Senior Lecturer in Climate Change, <a href="https://theconversation.com/institutions/university-of-waikato-781">University of Waikato</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Connection, camaraderie and belonging: why the Matildas could be making you a sports fan for the very first time

<a href="https://theconversation.com/profiles/sarah-tillott-1462234">Sarah Tillott</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> and <a href="https://theconversation.com/profiles/diarmuid-hurley-1462235">Diarmuid Hurley</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a> With over seven million Australians hooked onto the world cup viewing, many who have never really been interested in sports have recently found themselves screaming at the TV, cheering in pubs and hugging complete strangers. Have you found yourself in this new legion of sports fans, and wondering how you got here? It is likely down to many factors. There is of course the incredible talent on display, the <a href="https://www.9news.com.au/national/world-cup-2023-matildas-captain-sam-kerr-gives-prized-gameworn-top-to-young-fan/b9e35f75-6d11-4148-af3a-ac3cd0c95c0c">kindness</a> players are showing on and off the field, and women and girls relating to players <a href="https://www.abc.net.au/news/2023-08-15/matildas-world-cup-sam-kerr-mary-fowler-inspire-diverse-fans/102713288">who look like them</a>. But it is also to do with the visibility and exposure of the game; the influence of our families and friends; the ways we are hardwired for connection; and the addictive nature of neurotransmitters. Like many Australians, we will be sure to not miss tonight’s game when Australia plays England in the semifinal – but first, here’s a look at all of these new emotions you may be experiencing. <h2>The social contagion</h2> With Australia as a host nation – and the incredible success of the Matildas – there has never been more visibility and focus on women’s football in Australia. Positive emotions and behaviours are contagious. Psychologists refer to “<a href="https://positivepsychology.com/emotional-contagion/">emotional contagion</a>” or “social contagion”, which describes how emotions, attitudes and behaviours spread through groups and crowds. In general, people just want to feel good! We enhance that feeling by forming positive social connections with other humans, sharing in a common experience, having a common goal and putting aside our differences. Being on the same side means we have something to share and celebrate in and, more importantly, someone to do it with. You’re likely feeling like you are part of something greater, and that has us all reaching for more by getting together to watch the next game. <blockquote class="twitter-tweet"> This. Is.

This world cup has had its share of ups and downs: superstar Sam Kerr’s injury; the crushing low of defeat to Nigeria; the high of the must-win-game against Canada; the electric edge-of-your-seat drama of the penalty shootout against France. We all share in these highs and lows. Sports can help <a href="https://doi.org/10.3390/socsci11110513">create positive social cohesion</a> by bringing people together. There is something very comforting about winning or losing as a group - whatever the result, we aren’t doing it alone! Sports <a href="https://www.huffpost.com/entry/how-sport-can-break-down_b_7927724">breaks down barriers</a>, forms <a href="https://doi.org/10.3390/socsci11110513">pro-social bonds</a> and <a href="https://www.weforum.org/agenda/2018/02/north-and-south-korea-have-shown-us-the-unifying-power-of-sport/">helps people unite</a> through a common goal. We get lost and escape into a world of togetherness, which feels great! The ability to laugh, cry or hold hands with people (both strangers and friends) in nervous moments is felt deep in our body. It is undeniable, palpable and reinforces our connectivity. These heightened emotions fast track our sense of belonging to a group. Meanwhile, there is something very primitive going on deep in the brain that may explain this phenomenon. <blockquote class="twitter-tweet"> Goosebumps.

Historically, working together towards a common goal improved our ability to survive. In a contemporary setting, when we belong to groups we unite through the notion of achieving a common vision. The “self” blends with the social. We evaluate our environment and look for links of commonality to achieve social harmony. This comes back to the notion of feeling good. When you are sharing a sporting event – watching together or talking about it after – you are sharing a safe space you can relate, engage and belong to. <h2>Shared experiences</h2> The reality of what sports can do to unite and change the way we connect is palpable through this world cup. We are all sharing a common experience which enables us to talk to complete strangers at the bus stop, on the train and when we are ordering our coffees at the local café. This shared experience enables us the confidence to strike up new conversations: sharing our pride, our fears and our emotions. We fast track our connections with people through sharing our vulnerabilities. Connections that could generally take years to form are happening in seconds. The moments to form those connections are more frequent as the success of our team continues. Matilda’s defender Claire Hunt <a href="https://www.matildas.com.au/video/230810huntpresser">spoke</a> of the collective belief the team has in their abilities. This collective belief has spread out from the team and their diehard supporters to become a source of national pride. <h2>We belong</h2> Sports creates a connection to something greater than yourself, an ability to ride the highs and lows of a team as you journey with them for the entire match! Notice the feeling of your heart beating through your chest (and that feedback coming through your smart watch as the high pulse rate alert is screaming at you!); feeling like you want to vomit and cry from the anticipation; the <a href="https://www.apa.org/monitor/oct05/mirror">tensing of your muscles</a> during every attempt at goal. Through Australia’s collective love, support and excitement behind the Matildas, we are in the process of forming our identity and becoming part of a family.

Gratitude amplified: Unlocking the key to happiness and deep connections

In today's fast-paced world, filled with negative news, challenging experiences, and personal losses, finding joy and gratitude can often be a difficult task. As we naturally tend to focus on the negative aspects of life, it becomes essential to pause and cultivate gratitude, which can have a profound impact on our lives and the lives of those around us. What is gratitude? Gratitude involves showing appreciation for the things in life that are important to you, and taking a moment to notice and acknowledge these moments have proven benefits of lifting mood and helping you feel more positive throughout the day. Have you ever stopped to notice that there is something to be grateful for every day if we just take stock? It could be a person who kindly let you merge into traffic, a refreshing breeze on a scorching day, a beautiful rainbow after a heavy downpour, or a thoughtful call or text from a friend. Gratitude is strongly and consistently associated with greater happiness. Gratitude helps people feel more positive emotions, relish good experiences, improve their health, deal with adversity, and build strong relationships. We also know that Gratitude begets gratitude, meaning that any kind act is likely to bring kindness back, in spades! Practice Gratitude – Write down 3 things per day <a href="https://theresilienceproject.com.au/">The Resilience Project</a> changed my life by introducing a simple practice: at the end of each day, we take five minutes to write down three things we are grateful for that happened that day. It could be as simple as a walk in the sun, a phone call from a friend, a stroll with your dog, or even a comforting cup of tea. Engaging in this exercise helps you articulate your gratitude and realise the abundance of things to be grateful for in our everyday lives. I personally experienced the transformative power of gratitude during the two years of COVID lockdown in Victoria while working full-time and home schooling my two boys, aged 8 and 10. Our family embraced this practice each night, which not only changed our outlook on life but also sparked positive conversations during dinner. Surprisingly, it was often the simplest things we were all grateful for, like homemade meals or cherished moments of togetherness. I distinctly remember preparing a hot meal and passing it over our neighbour's fence when their family was unwell with COVID. To our surprise, a few weeks later, they reciprocated with a homecooked meal. In those challenging times, a sense of community became such a source of positivity, and we were immensely grateful for the love that went into that dinner. So why not take the time to stop and smell the roses and practice gratitude? Who knows, over time, you may start to notice your stress levels decreasing, your relationships improving, and be blessed with a strengthened sense of community.

Why does my back get so sore when I’m sick? The connection between immunity and pain

<a href="https://theconversation.com/profiles/joshua-pate-1399299">Joshua Pate</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/mark-hutchinson-105409">Mark Hutchinson</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Have you ever wondered why your back aches when you’re down with the flu or a cold? Or COVID? This discomfort, common during many illnesses, is not just a random symptom. It’s a result of complex interactions between your immune system and your brain called the “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3314453/">neuroimmune synapse</a>”. A fascinating and yet-to-be-understood consequence of this conversation between the immune and brain systems during sickness is that it is particularly noticeable in the <a href="https://academic.oup.com/brain/article/145/3/1098/6370954">lower back</a>. This is thought to be one of the body’s most sensitive regions to neuroimmune threats. <h2>Immunology basics</h2> Our immune system is a double-edged sword. Yes, it fights off infections for us – but it also makes us acutely aware of the job it is doing. When our body detects an infection, our immune system releases molecules including signalling proteins called <a href="https://www.researchgate.net/publication/227831648_The_functions_of_cytokines_and_their_uses_in_toxicology">cytokines</a>. These proteins coordinate our immune system to fight off the infection and talk to our brain and spinal cord to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2740752/#:%7E:text=Production%20of%20proinflammatory%20cytokines%20induces,to%20depression%20in%20vulnerable%20individuals.">change our behaviour</a> and physiology. This can result in symptoms like fatigue, loss of appetite, fever and increased sensitivity to pain. Classically, we think of this as a beneficial behavioural change to help us conserve energy to fight off the infection. It’s why we often feel the need to rest and withdraw from our usual activities when we’re sick – and also why we are grumpier than usual. <h2>Invisibly small changes</h2> Part of this self-protective response is a change in how we perceive threats, including sensory stimuli. When we are sick, touch can become painful and muscles can ache. Many changes in behaviour and sensory systems are <a href="https://doi.org/10.1159/000521476">believed</a> to have origins at the nanoscale. When molecular changes occur in part of the brain linked to cognition or mood, we think and feel differently. If these neuroimmune synapse changes happen in the sensory processing regions of the brain and spinal cord, we feel more pain. Such sensory changes, known as <a href="https://www.iasp-pain.org/resources/fact-sheets/allodynia-and-hyperalgesia-in-neuropathic-pain/#:%7E:text=Allodynia%20is%20pain%20due%20to,stimulus%20that%20normally%20provokes%20pain.">allodynia and hyperalgesia</a>, can lead to heightened pain sensitivity, even in areas not directly affected by the infection – <a href="https://www.sciencedirect.com/science/article/abs/pii/S0889159114001731?via%3Dihub">such as the lower back</a>. <h2>Immune memories</h2> This immune response happens with a range of bacterial infections and viruses like COVID or the flu. In fact, the sick feeling we sometimes get after a vaccination is the good work our immune system is doing to contribute to <a href="https://theconversation.com/you-cant-get-influenza-from-a-flu-shot-heres-how-it-works-118916">a protective immune memory</a>. Some of that immune-cellular conversation also alerts our brains that we are sick, or makes us think we are. After some viral infections, the sick feeling persists longer than the virus. We are seeing a long-term response to COVID in some people, termed <a href="https://theconversation.com/when-does-covid-become-long-covid-and-whats-happening-in-the-body-when-symptoms-persist-heres-what-weve-learnt-so-far-188976">long COVID</a>. Women, who generally have a <a href="https://www.nature.com/articles/nri.2016.90">stronger immune response</a> than men, may be more likely to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7937378/">experience pain symptoms</a>. Their heightened immune response (while beneficial in resisting infections) also predisposes women to a higher risk of inflammatory conditions like <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7980266/">autoimmune diseases</a>. <h2>When to worry and what to do</h2> If the pain is severe, persistent, or accompanied by other concerning symptoms, seek medical attention. Mild to moderate pain is a common symptom during illness and we often notice this in the lower back. The good news is it usually subsides as the infection clears and the sickness resolves. While treating the underlying infection is crucial, there are also ways to dial down sickness-induced neuroimmune pain. Maintaining a diverse microbiome (the collection of microorganisms living in and on your body) by <a href="https://pubmed.ncbi.nlm.nih.gov/31704402/">eating well and getting outside</a> can help. Getting quality sleep, staying hydrated and minimising inflammation <a href="https://karger.com/bbe/article/97/3-4/197/821576/Sickness-and-the-Social-Brain-How-the-Immune">helps too</a>. Amazingly, there is <a href="https://pubmed.ncbi.nlm.nih.gov/34404209/">research</a> suggesting your grandmother’s traditional chicken broth recipe decreases the immune signals at the neuroimmune synapse. Scientists are also <a href="https://pubmed.ncbi.nlm.nih.gov/24799686/">showing</a> mindfulness meditation, cold water therapy and controlled breathing can drive profound cellular and molecular changes to help activate bodily systems like the autonomic nervous system and alter the immune response. These practices might not only help manage pain but also add an anti-inflammatory component to the immune response, reducing the severity and duration of sickness. Heat treatment (with a pack or hot water bottle) might <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8401625/">provide some relief</a> due to increased circulation. Over-the-counter pain relief maybe also be helpful but seek advice if you are taking other medications. <h2>All in the mind?</h2> Is this all mind over matter? A little of yes and a lot of no. The little of yes comes from <a href="https://pubmed.ncbi.nlm.nih.gov/26194270/">research</a> supporting the idea that if you expect your breathing, meditation and cold bath therapy to work, it may well make a difference at the cellular and molecular level. But by understanding the mechanisms of back pain during illness and by using some simple strategies, there is hope to manage this pain effectively. Always remember to seek medical help if your symptoms are severe or persist longer than expected. Your health and comfort are paramount.<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/207222/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/joshua-pate-1399299">Joshua Pate</a>, Senior Lecturer in Physiotherapy, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/mark-hutchinson-105409">Mark Hutchinson</a>, Professor, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<a href="https://theconversation.com/profiles/jonathan-bamber-102567">Jonathan Bamber</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> The Arctic Ocean could be ice-free in summer by the 2030s, even if we do a good job of reducing emissions between now and then. That’s the worrying conclusion of a new study in <a href="https://www.nature.com/articles/s41467-023-38511-8">Nature Communications</a>. Predictions of an ice-free Arctic Ocean have a long and complicated history, and the 2030s is sooner than most scientists had thought possible (though it is later than some had wrongly forecast). What we know for sure is the disappearance of sea ice at the top of the world would not only be an emblematic sign of climate breakdown, but it would have global, damaging and dangerous consequences. The Arctic has been experiencing climate heating <a href="https://theconversation.com/arctic-is-warming-nearly-four-times-faster-than-the-rest-of-the-world-new-research-188474">faster than any other part of the planet</a>. As it is at the frontline of climate change, the eyes of many scientists and local indigenous people have been on the sea ice that covers much of the Arctic Ocean in winter. This thin film of frozen seawater expands and contracts with the seasons, reaching a minimum area in September each year. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?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/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=184&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=184&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=184&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=232&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=232&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530136/original/file-20230605-19-mdh85y.gif?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=232&fit=crop&dpr=3 2262w" alt="Animation of Arctic sea ice from space" /></a><figcaption>Arctic sea ice grows until March and then shrinks until September. <a class="source" href="https://www.nasa.gov/feature/esnt/2022/nasa-finds-2022-arctic-winter-sea-ice-10th-lowest-on-record">NASA</a></figcaption></figure> The ice which remains at the end of summer is called multiyear sea ice and is considerably thicker than its seasonal counterpart. It acts as barrier to the transfer of both moisture and heat between the ocean and atmosphere. Over the past 40 years this multiyear sea ice has shrunk from around <a href="http://polarportal.dk/en/sea-ice-and-icebergs/sea-ice-extent0/">7 million sq km to 4 million</a>. That is a loss equivalent to roughly the size of India or 12 UKs. In other words, it’s a big signal, one of the most stark and dramatic signs of fundamental change to the climate system anywhere in the world. As a consequence, there has been considerable effort invested in determining when the Arctic Ocean might first become ice-free in summer, sometimes called a “blue ocean event” and defined as when the sea ice area drops below 1 million sq kms. This threshold is used mainly because older, thicker ice along parts of Canada and northern Greenland is expected to remain long after the rest of the Arctic Ocean is ice-free. We can’t put an exact date on the last blue ocean event, but one in the near future would likely mean open water at the North Pole for the first time in <a href="https://www.nature.com/articles/nature10581">thousands of years</a>. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.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/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=712&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=712&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=712&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=895&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=895&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530138/original/file-20230605-29-9uuhxu.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=895&fit=crop&dpr=3 2262w" alt="Annotated map of Arctic" /></a><figcaption>The thickest ice (highlighted in pink) is likely to remain even if the North Pole is ice-free. <a class="source" href="https://nsidc.org/arcticseaicenews/2015/05/new-tools-for-sea-ice-thickness/">NERC Center for Polar Observation and Modelling</a>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></figcaption></figure> One problem with predicting when this might occur is that sea ice is notoriously difficult to model because it is influenced by both atmospheric and oceanic circulation as well as the flow of heat between these two parts of the climate system. That means that the climate models – powerful computer programs used to simulate the environment – need to get all of these components right to be able to accurately predict changes in sea ice extent. <h2>Melting faster than models predicted</h2> Back in the 2000s, an assessment of early generations of climate models found they generally <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2007GL029703">underpredicted the loss of sea ice</a> when compared to satellite data showing what actually happened. The models predicted a loss of about 2.5% per decade, while the observations were closer to 8%. The next generation of models did better but were <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2012GL052676">still not matching observations</a> which, at that time were suggesting a blue ocean event would happen by mid-century. Indeed, the latest <a href="https://www.ipcc.ch/report/sixth-assessment-report-working-group-i/">IPCC climate science report</a>, published in 2021, reaches a similar conclusion about the timing of an ice-free Arctic Ocean. As a consequence of the problems with the climate models, some scientists have attempted to extrapolate the observational record resulting in the controversial and, ultimately, incorrect assertion that this would happen <a href="https://www.theguardian.com/environment/2016/aug/21/arctic-will-be-ice-free-in-summer-next-year">during the mid 2010s</a>. This did not help the credibility of the scientific community and its ability to make reliable projections. <h2>Ice-free by 2030?</h2> The scientists behind the latest study have taken a different approach by, in effect, calibrating the models with the observations and then using this calibrated solution to project sea ice decline. This makes a lot of sense, because it reduces the effect of small biases in the climate models that can in turn bias the sea ice projections. They call these “observationally constrained” projections and find that the Arctic could become ice-free in summer as early as 2030, even if we do a good job of reducing emissions between now and then. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=394&fit=crop&dpr=1 600w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=394&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=394&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=495&fit=crop&dpr=1 754w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=495&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/530365/original/file-20230606-21-usmovg.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=495&fit=crop&dpr=3 2262w" alt="Walruses on ice floe" /></a><figcaption>Walruses depend on sea ice.

But compared to previous research, the new study still brings forward the most likely timing of a blue ocean event by about a decade. <h2>Why this matters</h2> You might be asking the question: so what? Other than some polar bears not being able to hunt in the same way, why does it matter? Perhaps there are even benefits as the previous US secretary of state, Mike Pompeo, <a href="https://edition.cnn.com/2019/05/06/politics/pompeo-sea-ice-arctic-council/index.html">once declared</a> – it means ships from Asia can potentially save around 3,000 miles of journey to European ports in summer at least. But Arctic sea ice is an important component of the climate system. As it dramatically reduces the amount of sunlight absorbed by the ocean, removing this ice is predicted to further accelerate warming, through a process known as a positive feedback. This, in turn, will make the Greenland ice sheet <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2014GL059770">melt faster</a>, which is already a major contributor to <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021RG000757">sea level rise</a>. The loss of sea ice in summer would also mean changes in <a href="https://www.ipcc.ch/report/ar6/wg2/chapter/ccp6/">atmospheric circulation and storm tracks</a>, and fundamental shifts in ocean biological activity. These are just some of the <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2021RG000757">highly undesirable consequences</a> and it is fair to say that the disadvantages will far outweigh the slender benefits. <a href="https://theconversation.com/profiles/jonathan-bamber-102567">Jonathan Bamber</a>, Professor of Physical Geography, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Three Aussie regions set to be unliveable

Three major economic centres are set to become uninhabitable by the end of the century as global temperatures are on track to warm by 2.7C. It is predicted that Broome, Darwin and Port Hedland in WA are to be pushed outside the “human climate niche”, referring to the temperature and humidity conditions in which humans can survive. The destinations are just three of the many northwestern sections of Australia facing “niche displacement” in the next 70 years. New research by The University of Exeter, published in the science journal Nature Sustainability in May 2023, calculates the human cost of climate inaction based on current insufficient policies and government inaction. According to the report, two million people will be living with unprecedented mean average temperatures (MAT) above 29C. MAT >29C is the point at which wellbeing scientifically declines, labour productivity and cognitive ability shrinks, negative pregnancy outcomes are emancipated and mortality rates soar. The report calculates that twenty per cent of Australia, around 374,977 Aussies, will be negatively impacted by the 2.7C temperature increase. Those Australians would join a third of the world’s population, including Africa, South America, and South-East Asia. A 3C warmer temperature in Darwin would mean that for 265 days of the year, temperatures would reach above 35C. At 40C, humidity soars and temperatures become lethal, the Australian Academy of Science reports. The University of Exeter report also explained the effects of a “wet-bulb temperature” where temperature and humidity are combined. In temperatures above 28C (WBT) body struggles to cool itself by sweating, and fails to do so in temperatures above 35C (WBT), which can be fatal. By limiting global warming to 1.5C, which is the goal of the Paris Agreement, 80 per cent of those at risk of rising temperatures would remain in their climate niche. However, scientists warn that a 1.5C will still cause severe and irreversible effects on people, wildlife and ecosystems. Global warming currently sits at 1.2C, but new research from The World Meteorological Organisation suggests there is a 66 per cent chance at least one year in the next five will breach the 1.5C threshold. “Despite increased pledges and targets to tackle climate change, current policies still leave the world on course for about 2.7C end-of-century global warming,” The University of Exeter report said. “These results highlight the need for more decisive policy action to limit the human costs and inequities of climate change.” The report also found the impacts of rising temperatures will not be felt equally, as estimates of the human cost of climate change “tend to be expressed in monetary terms”. “(Estimates) tends to recognise impacts on the rich more than those on the poor (because the rich have more money to lose) and tend to value those living now over those living in the future (because future damages are subject to economic discounting),” the report said. “From an equity standpoint, this is unethical — when life or health are at stake, all people should be considered equal, whether rich or poor, alive or yet to be born.” Image credit: Shutterstock

COVID is officially no longer a global health emergency – here’s what that means (and what we’ve learned along the way)

World Health Organisation (WHO) experts <a href="https://www.nytimes.com/2023/05/05/health/covid-who-emergency-end.html">have officially declared</a> that COVID <a href="https://www.who.int/news/item/05-05-2023-statement-on-the-fifteenth-meeting-of-the-international-health-regulations-(2005)-emergency-committee-regarding-the-coronavirus-disease-(covid-19)-pandemic">no longer constitutes</a> a public health emergency of international concern (Pheic). This coincides with the WHO’s new <a href="https://www.who.int/publications/i/item/WHO-WHE-SPP-2023.1">strategy</a> to transition from an emergency response to longer-term sustained COVID disease management. This may not change too much practically. COVID will still have pandemic status, and countries will continue to have their own authority as to whether to treat COVID as an emergency within their territories (some countries, <a href="https://www.npr.org/2023/04/11/1169191865/biden-ends-covid-national-emergency">including the US</a>, have already declared an end to the national emergency). For the global public health community, however, this is an event of monumental importance, drawing to a close the emergency response period which commenced on <a href="https://www.who.int/publications/m/item/covid-19-public-health-emergency-of-international-concern-(pheic)-global-research-and-innovation-forum">January 30 2020</a>. At the same time, for a large portion of the general public, it may well pass by relatively unnoticed. For many people, it’s been a long time since they viewed COVID as an emergency. In the UK for example, COVID no longer features in the regular Office for National Statistics <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/19aprilto1may2023">public opinion survey</a> that asks people what they think the key issues facing the country are. Even a year ago, <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/bulletins/publicopinionsandsocialtrendsgreatbritain/30marchto24april2022">only two in five Britons</a> were very or somewhat worried about COVID, according to the survey. Along with other behavioural scientists, I have been following <a href="https://www.swansea.ac.uk/research/research-highlights/health-innovation/public-during-pandemic/">public experiences of the pandemic</a> for the past three years. The results have yet to be peer reviewed but by summer 2022, many participants in <a href="https://psyarxiv.com/d6jcv">our research</a> described the pandemic as being like “a distant memory” or like it “never happened”. As we move into this next phase, it’s time to consider what we’ve learned about human behaviour during the pandemic, and what happens next. <h2>Old habits die hard</h2> In the early days of the pandemic, many behavioural scientists, myself included, wondered whether some of our pandemic habits <a href="https://theconversation.com/two-years-into-the-pandemic-which-of-our-newly-formed-habits-are-here-to-stay-178204">were here to stay</a>. Would <a href="https://www.itv.com/news/wales/2021-04-02/masks-to-stay-soldiering-on-through-the-common-cold-will-stop-and-the-nature-of-work-has-changed-forever-expert-says">face masks</a> become a regular wardrobe staple? Would people stop “soldiering on” and going into work when unwell? It turned out that for most people, the pandemic hasn’t permanently changed our behaviour and habits or created a “<a href="https://psyarxiv.com/d6jcv">new normal</a>”. Looking again at the UK, face mask use has consistently declined, with <a href="https://www.ons.gov.uk/peoplepopulationandcommunity/wellbeing/datasets/publicopinionsandsocialtrendsgreatbritaincoronaviruscovid19andotherillnesses">figures from last month</a> suggesting that fewer than one in six adults had worn a face mask recently. Regular use is likely much less common. Social distancing has long since disappeared, except for a relatively small proportion of the public, in particular those most vulnerable to COVID. The COVID pandemic has taught us how adaptive behaviour can be, in particular how much people were willing to change their behaviour to keep themselves and others safe. Most people <a href="https://academic.oup.com/abm/article/56/8/781/6618645?login=false">followed the rules</a> during <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0258781">the height of the pandemic</a>, no matter how difficult. COVID has reminded us <a href="https://www.cambridge.org/core/services/aop-cambridge-core/content/view/759BE02FFE73E5C05EA429A3E1547D78/S2056467821000050a.pdf/resilience_in_the_age_of_covid19.pdf">how resilient we humans can be</a>. These pandemic adaptions, and the fact that our pre-pandemic behaviour bounced back so quickly, shows how important social cues and social norms are to behaviour. Putting on a mask or keeping our distance from others were habits – <a href="https://www.sciencedirect.com/science/article/abs/pii/S002210311100254X">actions triggered automatically</a> in response to contextual cues, such as seeing signs with pictures of people socially distancing. Social norms – what we think others are doing – were key to <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0277360">vaccine uptake</a> and to our uptake of <a href="https://www.nature.com/articles/s41562-020-0884-z">preventative measures in general</a>. As these contextual cues disappeared and the social norms started to change, and as vaccine coverage increased and the risk to the majority decreased, our behaviour changed. The pandemic has also demonstrated how important social connections and social, especially physical, contact can be. This is something <a href="https://theconversation.com/handshakes-and-hugs-are-good-for-you-its-vital-they-make-a-comeback-after-the-pandemic-158174">we have already argued</a> COVID couldn’t keep at bay forever. According to social safety theory, which sees stress and wellbeing as a product of biological, psychological and social factors, COVID <a href="https://www.sciencedirect.com/science/article/pii/S2352250X2200001X">posed a threat</a> to the “social fabric that makes humans resilient and keeps us alive and well”. It’s unsurprising that life satisfaction and happiness were <a href="https://bmjopen.bmj.com/content/10/7/e039334">lowest during lockdowns</a>, and <a href="https://www.covidsocialstudy.org/_files/ugd/064c8b_c525505ffa6b432f96dc41d6b6a985ea.pdf">recovered as people started to mix socially again</a>. <h2>The emergency isn’t over for everyone</h2> As we mark the end of the emergency phase it’s important to remember the <a href="https://covid19.who.int/">nearly seven million lives lost</a> due to COVID since 2020. And of course, we must consider that for some, especially those who are clinically vulnerable, the emergency is not yet over, and may never be. Although it’s no longer a Pheic, <a href="https://www.who.int/publications/i/item/WHO-WHE-SPP-2023.1">as the WHO reminds us</a>, COVID is still responsible for millions of infections and thousands of deaths each week around the world. Also, thanks to long COVID, hundreds of millions of people are in need of longer-term care. In the future, we need to move from relying on the resilience of individuals to building resilience in our institutions. We can all take measures to continue to protect ourselves and those around us from COVID and other respiratory viruses (such as by <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00021-1/fulltext">hand washing</a> and keeping up to date with vaccinations). But responsibility for preventing public health emergencies shouldn’t rest <a href="https://blogs.bmj.com/bmj/2020/03/17/uks-coronavirus-policy-places-too-much-responsibility-in-the-hands-of-the-public/">solely in the hands of the public</a> Actions that governments, employers and health authorities can take now could <a href="https://www.theguardian.com/books/2022/may/11/preventable-by-devi-sridhar-review-a-resolutely-global-view-of-covid">protect against</a> future <a href="https://pubmed.ncbi.nlm.nih.gov/34872923/">public health emergencies</a>. Systematically <a href="https://joint-research-centre.ec.europa.eu/jrc-news/misinformation-covid-19-what-did-we-learn-2023-02-21_en">tackling misinformation</a>, <a href="https://www.who.int/publications/i/item/9789240021280">improving ventilation</a> in <a href="https://www.bmj.com/content/376/bmj.o327">schools</a>, workplaces and other public indoor spaces, and making longer-term improvements to paid sick leave are all good ways to start building more <a href="https://unsdg.un.org/resources/executive-summary-un-common-guidance-helping-build-resilient-societies">resilient societies</a> in preparation for the next pandemic.

Matthew McConaughey's surprising connection to Woody Harrelson

Matthew McConaughey has shared a revelation about his relationship with his friend and Hollywood co-star Woody Harrelson. The acting duo, who notably shared the screen on the debut season of acclaimed crime drama True Detective in 2014, have been friends long before they ever acted on screen together. Now it has been revealed their bromance could have even greater ties, as the actors could be blood related. McConaughey, 53, and Harrelson, 61, are set to reunite on screen for an upcoming Apple TV+ comedy series, titled Brother From Another Mother, which triggered the conversation about their relationship. Appearing on the <a href="https://podcasts.apple.com/us/podcast/lets-talk-off-camera-with-kelly-ripa/id1676166337" target="_blank" rel="noopener">Let’s Talk Off Camera with Kelly Ripa</a> podcast, McConaughey shared that the pair could actually share the same father. “You know, where I start and where he ends, and where he starts and I end, has always been like a murky line,” McConaughey began. He continued, “In Greece a few years ago, we’re sitting around talking about how close we are and our families,” McConaughey said. “And my mum [Mary Kathlene McCabe] is there, and she says, ‘Woody, I knew your dad’ … Everyone was aware of the ellipses that my mum left after ‘knew.’ It was a loaded ‘knew’." “We went on to unpack what this ‘knew’ meant and did some math and found out that [Harrelson’s] dad [Charles Harrelson] was on furlough at the same time that my mum and dad [James Donald McConaughey] were in their second divorce. Then there’s possible receipts and places out in West Texas where there might have been a gathering, or a meeting, or a ‘knew’ moment.” McConaughey said he and Harrelson are "on the precipice" of getting DNA testing done to uncover the truth, but McConaughey shared he has reservations because he’s spent “53 years believing” his dad James was his biological father. Both their fathers have passed away, with James dying of a heart attack in 1992, and Charles, a notorious US hit man and organised crime figure, also dying of a heart attack in his jail cell in 2007.

As the global musical phenomenon turns 50, a hip-hop professor explains what the word ‘dope’ means to him

After I finished my Ph.D. in 2017, several newspaper reporters wrote about the job I’d accepted at the University of Virginia as an assistant professor of hip-hop. “A.D. Carson just scored, arguably, the dopest job ever,” one <a href="https://www.usatoday.com/story/news/2017/07/03/virginia-ad-carson-hip-hop-professor/435032001/">journalist wrote</a>. The writer may not have meant it the way I read it, but the terminology was significant to me. Hip-hop’s early luminaries transformed the word’s original meanings, using it as a synonym for cool. In the 50 years since, it endures as an expression of respect and praise – and illegal substances. In that context, dope has everything to do with my work. In the year I graduated from college, one of my best friends was sent to federal prison for possession of crack cocaine with intent to distribute. He served nearly a decade and has been back in prison several times since. But before he went to prison, he helped me finish school by paying off my tuition. In a very real way, dope has as much to do with me finishing my studies and becoming a professor as it does with him serving time in a federal prison. <h2>Academic dope</h2> For my Ph.D. dissertation in Rhetorics, Communications, and Information Design, I wrote a <a href="http://phd.aydeethegreat.com/">rap album</a> titled “Owning My Masters: The Rhetorics of Rhymes & Revolutions.” A peer-reviewed, mastered version of the album is due out this summer from University of Michigan Press. Part of my reasoning for writing it that way involved my ideas about dope. I want to question who gets to determine who and what are dope and whether any university can produce expertise on the people who created hip-hop. While I was initially met with <a href="https://www.theatlantic.com/national/archive/2016/04/clemson-university-arrests/478455/">considerable resistance</a> for my work at Clemson, the university eventually became supportive and touted “<a href="https://news.clemson.edu/clemson-doctoral-student-produces-rap-album-for-dissertation-it-goes-viral/">a dissertation with a beat</a>.” <blockquote class="twitter-tweet"> A Dissertation with a Beat. 🔊🎤 🔊<a href="https://twitter.com/hashtag/Clemson?src=hash&ref_src=twsrc%5Etfw">#Clemson</a> doctoral student produces rap album for dissertation; it goes viral ➡️ <a href="https://t.co/wgiM9LS6k5">https://t.co/wgiM9LS6k5</a> <a href="https://t.co/r1lmBYXV2S">pic.twitter.com/r1lmBYXV2S</a> — Clemson University (@ClemsonUniv) <a href="https://twitter.com/ClemsonUniv/status/845990987440652289?ref_src=twsrc%5Etfw">March 26, 2017</a></blockquote> Clemson is not the only school to recognize hip-hop as dope. In the 50 years since its start at <a href="https://theconversation.com/hip-hop-holiday-signals-a-turning-point-in-education-for-a-music-form-that-began-at-a-back-to-school-party-in-the-bronx-165525">a back-to-school party</a> in the South Bronx, hip-hop, the culture and its art forms have come a long way to a place of relative prominence in educational institutions. Since 2013, Harvard University has housed the <a href="https://hutchinscenter.fas.harvard.edu/institutes/hiphop-archive-research-institute">Hiphop Archive & Research Institute</a> and the <a href="https://hutchinscenter.fas.harvard.edu/faq/nasir-jones-hiphop-fellowship">Nasir Jones Hiphop Fellowship</a> that funds scholars and artists who demonstrate “exceptional scholarship and creativity in the arts in connection with Hiphop.” UCLA announced an <a href="https://www.latimes.com/entertainment-arts/music/story/2022-03-28/ucla-hip-hop-initiative-chuck-d">ambitious Hip Hop Initiative</a> to kick off the golden anniversary. The initiative includes artist residencies, community engagement programs, a book series and a digital archive project. Perhaps my receiving tenure and promotion at the University of Virginia is part of the school’s attempt to help codify the existence of hip-hop scholarship. When I write about “dope,” I’m thinking of Black people like drugs to which the U.S. is addicted. Dope is a frame to help clarify the attempts, throughout American history, at outlawing and <a href="https://www.ilsos.gov/departments/archives/online_exhibits/100_documents/1853-black-law.html">legalizing</a> the presence of Black people and Black culture. As dope, Black people are America’s constant ailment and cure. To me, dope is an aspiration and a methodology to acknowledge and resist America’s steady surveillance, scrutiny and criminalization of Blackness. By this definition, dope is not only what we are, it’s also who we want to be and how we demonstrate our being. Dope is about what we can make with what we are given. Dope is a product of conditions created by America. It is also a product that helped create America. Whenever Blackness has been seen as lucrative, businesses like record companies and institutions like colleges and universities have sought to capitalize. To remove the negative stigmas associated with dope, these institutions cast themselves in roles similar to a pharmacy. Even though I don’t believe academia has the power or authority to bestow hip-hop credibility, a question remains – does having a Ph.D and producing rap music as <a href="https://theconversation.com/hip-hop-professor-looks-to-open-doors-with-worlds-first-peer-reviewed-rap-album-153761">peer-reviewed publications</a>change my dopeness in some way? <h2>Legalizing dope</h2> Though I earned a Ph.D by rapping, my own relationship to hip-hop in academic institutions remains fraught. Part of the problem was noted in 2014 by Michelle Alexander, a legal scholar and author of “<a href="http://newjimcrow.com/">The New Jim Crow</a>,” when she talked about <a href="http://www.drugpolicy.org/resource/new-jim-crow-whats-next-talk-michelle-alexander-and-dpas-asha-bandele">her concerns about</a> the legalization of marijuana in different U.S. states. “In many ways the imagery doesn’t sit right,” she said. “Here are white men poised to run big marijuana businesses … after 40 years of impoverished black kids getting prison time for selling weed, and their families and futures destroyed. Now, white men are planning to get rich doing precisely the same thing?” I feel the same way about dopeness in academia. Since hip-hop has emerged as a global phenomenon largely embraced by many of the “academically trained” music scholars who initially rejected it, how will those scholars and their schools now make way for the people they have historically excluded? This is why that quote about me “scoring, arguably, the dopest job ever” has stuck with me. I wonder if it’s fair to call what I do a form of legalized dope. <h2>America’s dope-dealing history</h2> In the late 1990s, I saw how fast hip-hop had become inescapable across the U.S., even in the small Midwestern town of Decatur, Illinois, where I grew up with my friend who is now serving federal prison time. He and I have remained in contact. Among the things we discuss is how unlikely it is that I would be able to do what I do without his doing what he did. Given the economic realities faced by people after leaving prison, we both know there are limitations to his opportunities if we choose to see our successes as shared accomplishments. Depending on how dope is interpreted, prisons and universities serve as probable destinations for people who make their living with it. It has kept him in prison roughly the same amount of time as it has kept me in graduate school and in my profession. This present reality has historical significance for how I think of dope, and what it means for people to have their existence authorized or legalized, and America’s relationship to Black people. Many of the buildings at Clemson were built in the late 1880s using “<a href="http://glimpse.clemson.edu/convict-labor/">laborers convicted of mostly petty crimes</a>” that the state of South Carolina leased to the university. Similarly, the University of Virginia was built by <a href="https://dei.virginia.edu/resources">renting enslaved laborers</a>. The University also is required by state law to purchase office furniture from a state-owned company that <a href="https://www.insidehighered.com/news/2020/02/14/public-universities-several-states-are-required-buy-prison-industries">depends on imprisoned people for labor</a>. The people who make the furniture are paid very little to do so. The people in the federal prison where my friend who helped me pay for college is now housed work for paltry wages making towels and shirts for the U.S. Army. Even with all of the time and distance between our pasts and present, our paths are still inextricably intertwined – along with all those others on or near the seemingly transient line that divides “legal” and “illegal” dope.

While there have long been concerns about the association between social media, body image and eating disorders the connection remains relatively unexplored as a public health issue. Now, researchers from University College London in the UK have undertaken a systematic review of 50 scientific studies across 17 countries showing clear links between social media use and body image concerns. The paper, <a href="https://doi.org/10.1371/journal.pgph.0001091" target="_blank" rel="noopener">published</a> in PLOS Global Public Health, analyses the relationship between body image or eating disorders in young people and social media use. The researchers identify specific aspects of social media – platforms with an emphasis on photos, and engaging with “fitspiration” and “thinspiration” trends – as the factors most closely linked to body image concerns, disordered eating and poor mental health. Other key risk factors included female gender, high body-mass-index and pre-existing body image concerns. The researchers note further studies are needed into the direction of causality. “For example, do body image dissatisfaction and disordered eating occur because of social media usage, or do these pre-exist, encourage engagement in certain online activities, and result in unfavourable clinically significant outcomes?” they ask. Eating disorders involve disturbed attitudes to body image, pre-occupation with weight and body shape and are associated with significant negative outcomes such as cardiovascular disease, reduced bone density, and psychiatric conditions. In Australia, the <a href="https://butterfly.org.au/" target="_blank" rel="noopener">Butterfly Foundation</a> reports eating disorders affect around one million people, with the conditions causing more people die each year than the road toll.
