Could not getting enough sleep increase your risk of type 2 diabetes?

<a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes. So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex. <h2>The study</h2> Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade. The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk. As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets. Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category. The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours. One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less. Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations. <h2>Why might short sleep increase diabetes risk?</h2> In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body. We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes. Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>. This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses. These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours. While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes. Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase. The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>. <h2>Good sleep, healthy diet</h2> Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes. Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle. While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health. The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk. In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<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/225179/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, Casual Academic, Faculty of Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, Senior Lecturer, School of Public Health, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mothers’ dieting habits and self-talk have profound impact on daughters − 2 psychologists explain how to cultivate healthy behaviors and body image

<a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J. Boseovski</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> and <a href="https://theconversation.com/profiles/ashleigh-gallagher-1505989">Ashleigh Gallagher</a>, <a href="https://theconversation.com/institutions/university-of-north-carolina-greensboro-2069">University of North Carolina – Greensboro</a> Weight loss is one of the most common health and appearance-related goals. Women and <a href="https://www.cdc.gov/nchs/products/databriefs/db340.htm">teen girls</a> are <a href="https://www.cdc.gov/nchs/products/databriefs/db313.htm">especially likely to pursue dieting</a> to achieve weight loss goals even though a great deal of research shows that <a href="https://theconversation.com/what-thin-people-dont-understand-about-dieting-86604">dieting doesn’t work over the long term</a>. We are a <a href="https://www.duck-lab.com/people">developmental psychologist</a> and a <a href="https://psy.uncg.edu/directory/ashleigh-gallagher/">social psychologist</a> who together wrote a forthcoming book, “Beyond Body Positive: A Mother’s Evidence-Based Guide for Helping Girls Build a Healthy Body Image.” In the book, we address topics such as the effects of maternal dieting behaviors on daughters’ health and well-being. We provide information on how to build a foundation for healthy body image beginning in girlhood. <h2>Culturally defined body ideals</h2> Given the strong influence of social media and other cultural influences on body ideals, it’s understandable that so many people pursue diets aimed at weight loss. <a href="https://communityhealth.mayoclinic.org/featured-stories/tiktok-diets">TikTok</a>, YouTube, Instagram and celebrity websites feature slim influencers and “how-tos” for achieving those same results in no time. For example, women and teens are engaging in rigid and extreme forms of exercise such as 54D, a program to <a href="https://54d.com/">achieve body transformation in 54 days</a>, or the <a href="https://health.clevelandclinic.org/75-hard-challenge-and-rules">75 Hard Challenge</a>, which is to follow five strict rules for 75 days. For teens, these pursuits are likely fueled by trendy body preoccupations such as the desire for “<a href="https://www.nytimes.com/2024/02/06/well/move/tiktok-legging-legs-eating-disorders.html">legging legs</a>.” Women and teens have also been been inundated with recent messaging around <a href="https://theconversation.com/drugs-that-melt-away-pounds-still-present-more-questions-than-answers-but-ozempic-wegovy-and-mounjaro-could-be-key-tools-in-reducing-the-obesity-epidemic-205549">quick-fix weight loss drugs</a>, which come with a lot of caveats. Dieting and weight loss goals are highly individual, and when people are intensely self-focused, it is <a href="https://doi.org/10.1521/jscp.2000.19.1.70">possible to lose sight of the bigger picture</a>. Although women might wonder what the harm is in trying the latest diet, science shows that dieting behavior doesn’t just affect the dieter. In particular, for women who are mothers or who have other girls in their lives, these behaviors affect girls’ emerging body image and their health and well-being. <h2>The profound effect of maternal role models</h2> Research shows that mothers and maternal figures <a href="https://doi.org/10.1016/j.brat.2017.11.001">have a profound influence on their daughters’ body image</a>. The opportunity to influence girls’ body image comes far earlier than adolescence. In fact, research shows that these influences on body image <a href="https://www.teenvogue.com/story/how-toxic-diet-culture-is-passed-from-moms-to-daughters">begin very early in life</a> – <a href="https://doi.org/10.1016/bs.acdb.2016.10.006">during the preschool years</a>. Mothers may feel that they are being discreet about their dieting behavior, but little girls are watching and listening, and they are far more observant of us than many might think. For example, one study revealed that compared with daughters of nondieting women, 5-year-old girls whose mothers dieted <a href="https://doi.org/10.1016/S0002-8223(00)00339-4">were aware of the connection between dieting and thinness</a>. Mothers’ eating behavior does not just affect girls’ ideas about dieting, but also their daughters’ eating behavior. The amount of food that mothers eat <a href="https://doi.org/10.1016/j.appet.2018.04.018">predicts how much their daughters will eat</a>. In addition, daughters whose mothers are dieters are <a href="https://doi.org/10.1016/j.appet.2018.04.018">more likely to become dieters themselves</a> and are also <a href="https://doi.org/10.1016/j.eatbeh.2007.03.001">more likely to have a negative body image</a>. Negative body image is <a href="https://theconversation.com/mounting-research-documents-the-harmful-effects-of-social-media-use-on-mental-health-including-body-image-and-development-of-eating-disorders-206170">not a trivial matter</a>. It affects girls’ and women’s mental and physical well-being in a <a href="https://doi.org/10.1177/1359105317710815">host of ways</a> and <a href="https://doi.org/10.1016/j.brat.2011.06.009">can predict the emergence of eating disorders</a>. <h2>Avoiding ‘fat talk’</h2> What can moms do, then, to serve their daughters’ and their own health? They can focus on small steps. And although it is best to begin these efforts early in life – in girlhood – it is never too late to do so. For example, mothers can consider how they think about and talk about themselves around their daughters. Engaging in “fat talk” may inadvertently send their daughters the message that larger bodies are bad, <a href="https://doi.org/10.1016/j.bodyim.2020.07.004">contributing to weight bias</a> and negative self-image. Mothers’ fat talk also <a href="https://doi.org/10.1080/15267431.2021.1908294">predicts later body dissatisfaction in daughters</a>. And negative self-talk isn’t good for mothers, either; it is associated with <a href="https://doi.org/10.1177/1359105318781943">lower motivation and unhealthful eating</a>. Mothers can instead practice and model self-compassion, which involves treating oneself the way <a href="https://doi.org/10.1016/j.bodyim.2016.03.003">a loving friend might treat you</a>. In discussions about food and eating behavior, it is important to avoid moralizing certain kinds of food by labeling them as “good” or “bad,” as girls may extend these labels to their personal worth. For example, a young girl may feel that she is being “bad” if she eats dessert, if that is what she has learned from observing the women around her. In contrast, she may feel that she has to eat a salad to be “good.” Moms and other female role models can make sure that the dinner plate sends a healthy message to their daughters by showing instead that all foods can fit into a balanced diet when the time is right. Intuitive eating, which emphasizes paying attention to hunger and satiety and allows flexibility in eating behavior, is associated with <a href="https://doi.org/10.1007/s40519-020-00852-4">better physical and mental health in adolescence</a>. Another way that women and especially moms can buffer girls’ body image is by helping their daughters <a href="https://doi.org/10.1016/j.bodyim.2021.12.009">to develop media literacy</a> and to think critically about the nature and purpose of media. For example, moms can discuss the misrepresentation and distortion of bodies, such as the use of filters to enhance physical appearance, on social media. <h2>Focusing on healthful behaviors</h2> One way to begin to focus on health behaviors rather than dieting behaviors is to develop respect for the body and to <a href="https://theconversation.com/body-neutrality-what-it-is-and-how-it-can-help-lead-to-more-positive-body-image-191799">consider body neutrality</a>. In other words, prize body function rather than appearance and spend less time thinking about your body’s appearance. Accept that there are times when you may not feel great about your body, and that this is OK. To feel and look their best, mothers can aim to stick to a <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">healthy sleep schedule</a>, manage their stress levels, <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">eat a varied diet</a> that includes all of the foods that they enjoy, and <a href="https://theconversation.com/the-runners-high-may-result-from-molecules-called-cannabinoids-the-bodys-own-version-of-thc-and-cbd-170796">move and exercise their bodies regularly</a> as lifelong practices, rather than engaging in quick-fix trends. Although many of these tips sound familiar, and perhaps even simple, they become effective when we recognize their importance and begin acting on them. Mothers can work toward modeling these behaviors and tailor each of them to their daughter’s developmental level. It’s never too early to start. <h2>Promoting healthy body image</h2> Science shows that several personal characteristics are associated with body image concerns among women. For example, research shows that women who are <a href="https://doi.org/10.1016/j.bodyim.2020.02.001">higher in neuroticism</a> <a href="https://doi.org/10.1186/2050-2974-1-2">and perfectionism</a>, <a href="https://doi.org/10.3389/fpsyg.2022.983534">lower in self-compassion</a> or <a href="https://doi.org/10.1016/j.bodyim.2013.08.001">lower in self-efficacy</a> are all more likely to struggle with negative body image. Personality is frequently defined as a person’s characteristic pattern of thoughts, feelings and behaviors. But if they wish, <a href="https://doi.org/10.1002/per.1945">mothers can change personality characteristics</a> that they feel aren’t serving them well. For example, perfectionist tendencies – such as setting unrealistic, inflexible goals – can be examined, challenged and replaced with more rational thoughts and behaviors. A woman who believes she must work out every day can practice being more flexible in her thinking. One who thinks of dessert as “cheating” can practice resisting moral judgments about food. Changing habitual ways of thinking, feeling and behaving certainly takes effort and time, but it is far more likely than diet trends to bring about sustainable, long-term change. And taking the first steps to modify even a few of these habits can positively affect daughters. In spite of all the noise from media and other cultural influences, mothers can feel empowered knowing that they have a significant influence on their daughters’ feelings about, and treatment of, their bodies. In this way, mothers’ modeling of healthier attitudes and behaviors is a sound investment – for both their own body image and that of the girls they love.<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/221968/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J.

Mum slammed for being "stingy" after refusing to buy $2 snack for daughter's playdate

A mum has come under fire for being "selfish" and "stingy" after refusing to buy a $2 snack for her 11-year-old daughter’s best friend. The woman, believed to be from the US, and her daughter Ellie were invited for a playdate at an indoor playground with 12-year-old Sophie and her mum. Sophie's mum offered to put them on her membership card so that Ellie and her mum could go to the indoor playground for free. “Sophie’s mum called me... and Sophie wanted to know if Ellie could come and play," she began in a Reddit thread called Am I the a****** . "She offered to put me on her membership card so it would be free for me so I got Ellie in the car and we met them at the playground.” Trouble started when the girls got hungry after an hour of playing, and Ellie's mum only packed a snack for her daughter. “Sophie’s mum didn’t have any snacks on her,” she said. “I told her they sell snacks in the front but she claimed that she didn’t have any money on her and asked me to buy Sophie some Goldfish." Ellie's mum agreed to grab the crackers on one condition - Sophie's mum had to transfer the money to her. “She says she paid for my kid to get in so I could cover the $2 for the Goldfish. I said no, I took care of my kid and it’s not my job to take care of hers too. “I told her if she wanted me to bring snacks she should’ve told me when she invited me but I won’t be wasting $2 for a 50 cent bag of Goldfish because she was unprepared.” She added that Sophie's mum eventually managed to get snacks for her own daughter, and wondered "if she lied about not having money". She then accused Sophie's mum of being "petty" for asking her to pay back for “all the times” she's used her membership to get a guest pass at the indoor playground, adding that "they regularly pay for us to join them on outings.” Her post was met with over 2500 comments slamming her for being “selfish”, “stingy” and “ungrateful”. “You were invited to a place for free that you would otherwise have had to pay for. You only packed snacks for your child? Why didn’t you also take snacks for the other child?" one wrote. “Yes, you did not have to do so, and that child is not your responsibility, but if I was meeting someone for a playdate for my child, not paying to get in, knowing, at some point both girls were going to be hungry, I would have packed snacks for both, as a thank you for the invitation and just because," the commenter continued. “If someone asked me to transfer them $2, I’m rolling my eyes big time. It’s petty, especially when someone gave you something likely far more valuable," another added. “Seriously. I don’t even think I could tell a stranger no when it comes to feeding their hungry child, much less a person I know and spend time with," a third commented. Others called the mum a "fool", for potentially causing Ellie to lose her best friend. “Don’t be an idiot. Apologise. You might care about 50 cents. But your daughter will lose her best friend. And that is worth a lot more. Your daughter might never get a friend like that... And the fact that universe gift wrapped a friend for your daughter. And you choose to throw it in the trash. Wow, you are truly a fool," they said. Image: Getty

"Did you forget?": Nicole Kidman hounded by angry fans

Nicole Kidman, the famous Aussie star with a Hollywood career spanning four decades, has found herself embroiled in controversy after she proudly announced her collaboration with fashion house Balenciaga. The announcement, made via Instagram, featured Kidman showcasing the brand's latest designs during their Fall 2024 show in Los Angeles. However, the excitement from Kidman was met with a swift and vehement response from fans who couldn't overlook the brand's troubling past. Balenciaga had <a href="https://www.oversixty.co.nz/lifestyle/beauty-style/why-people-are-calling-for-nicole-kidman-to-be-cancelled" target="_blank" rel="noopener">previously come under fire</a> for a controversial photoshoot that sparked widespread criticism and accusations of "paedophilia" and "child exploitation". The offending campaign featured children clad in bondage harnesses and costumes, causing an immediate uproar online. The hashtag #cancelBalenciaga trended across social media platforms at the time, putting immense pressure on the fashion brand to issue an apology. Despite the global backlash last year, Kidman's recent association with Balenciaga has reignited the flames of discontent. Fans flooded the comments section of her Instagram post with expressions of disappointment and frustration. One user implored Kidman, stating, "Seriously? Come on Nic. You're better than this. UGH." Another echoed the sentiment, saying, "No. You too. Did you forget? This designer has been cancelled. They promote ads the public didn't want. It was wrong." The criticism did not stop there, with another fan expressing their disappointment: "Well, that's disappointing, but not surprising, really." Another comment labelled Kidman's decision as "disgusting", highlighting the continued disapproval of Balenciaga's controversial past. This incident raises questions about celebrities' responsibilities when endorsing brands and the impact of their choices on public opinion. Kidman, who has previously shared her approach to online criticism, has made it clear that her preference is to avoid such feedback to maintain creative freedom. In a recent interview, she revealed, "Don't tell me, I don't really want to know – it will stop me doing what I want to do." Kidman acknowledged the existence of hurtful comments but emphasised her commitment to staying true to her choices. While Kidman's determination to navigate her career with a focus on personal choices and creative freedom is understandable, her association with a brand that has faced severe backlash for controversial practices inevitably places her in the centre of a heated public debate. As the controversy unfolds, it remains to be seen how Kidman will address the mounting criticism and whether this incident will prompt a response from Balenciaga. Images: Instagram

What happens in our body when we encounter and fight off a virus like the flu, SARS-CoV-2 or RSV?

<a href="https://theconversation.com/profiles/lara-herrero-1166059">Lara Herrero</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/wesley-freppel-1408971">Wesley Freppel</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> <a href="https://www.labcorp.com/coronavirus-disease-covid-19/covid-news-education/covid-19-vs-flu-vs-rsv-how-tell-difference">Respiratory viruses</a> like influenza virus (flu), SARS-CoV-2 (which causes COVID) and respiratory syncytial virus (RSV) can make us sick by infecting our respiratory system, including the nose, upper airways and lungs. They spread from person to person through respiratory droplets when someone coughs, sneezes, or talks and can cause death in serious cases. But what happens in our body when we first encounter these viruses? Our immune system uses a number of strategies to fight off viral infections. Let’s look at how it does this. <h2>First line of defence</h2> When we encounter respiratory viruses, the <a href="https://www.sciencedirect.com/science/article/pii/S193131281600038X?via%3Dihub/">first line of defence</a> is the physical and chemical barriers in our nose, upper airways, and lungs. Barriers like the mucus lining and hair-like structures on the surface of cells, work together to trap and remove viruses before they can reach deeper into our respiratory system. Our defence also includes our behaviours such as coughing or sneezing. When we blow our nose, the mucus, viruses, and any other pathogens that are caught within it are expelled. But sometimes, viruses manage to evade these initial barriers and sneak into our respiratory system. This activates the cells of our innate immune system. <h2>Patrolling for potential invaders</h2> While our acquired immune system develops over time, our innate immune system is present at birth. It generates “non-specific” immunity by identifying what’s foreign. The cells of innate immunity act like a patrol system, searching for any invaders. These innate cells patrol almost every part of our body, from our skin to our nose, lungs and even internal organs. Our respiratory system has different type of innate cells such – as macrophages, neutrophils and natural killer cells – which patrol in our body looking for intruders. If they recognise anything foreign, in this case a virus, they will initiate an attack response. Each cell type plays a slightly different role. Macrophages, for example, will not only engulf and digest viruses (phagocytosis) but also release a cocktail of different molecules (cytokines) that will warn and recruit other cells to <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/cmi.12580">fight against the danger</a>. In the meantime, natural killer cells, aptly named, attack infected cells, and stop viruses from multiplying and <a href="https://www.nature.com/articles/s41577-021-00558-3">invading our body further</a>. Natural killer cells also promote inflammation, a <a href="https://www.hindawi.com/journals/jir/2018/1467538/">crucial part of the immune response</a>. It helps to recruit more immune cells to the site of infection, enhances blood flow, and increases the permeability of blood vessels, allowing immune cells to reach the infected tissues. At this stage, our immune system is fighting a war against viruses and the result can cause inflammation, fevers, coughs and congestion. <h2>Launching a specific attack</h2> As the innate immune response begins, another branch of the immune system called the adaptive immune system is <a href="https://www.ncbi.nlm.nih.gov/books/NBK21070/">activated</a>. The adaptive immune system is more specific than the innate immune system, and it decides on the correct tools and strategy to fight off the viral invaders. This system plays a vital role in eliminating the virus and providing long-term protection against future infections. Specialised cells called T cells and B cells are key players in acquired immunity. T cells (specifically, helper T cells and cytotoxic T cells) recognise viral proteins on the surface of infected cells: <ul> <li> helper T cells release molecules that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764486/">further activate immune cells</a> </li> <li> cytotoxic T cells directly kill infected cells with a very great precision, <a href="https://www.frontiersin.org/articles/10.3389/fimmu.2018.00678/full">avoiding any healthy cells around</a>. </li> </ul> B cells produce antibodies, which are proteins that can bind to viruses, neutralise them, and mark them for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7247032/">destruction by other immune cells</a>. B cells are a critical part of memory in our immune system. They will remember what happened and won’t forget for years. When the same virus attacks again, B cells will be ready to fight it off and will neutralise it faster and better. Thanks to the adaptive immune system, vaccines for respiratory viruses such as the COVID mRNA vaccine keep us protected from <a href="https://www.health.gov.au/our-work/covid-19-vaccines/our-vaccines/how-they-work">being sick or severely ill</a>. However, if the same virus became mutated, our immune system will act as if it was a new virus and will have to fight in a war again. <h2>Neutralising the threat</h2> As the immune response progresses, the combined efforts of the innate and adaptive immune systems helps control the virus. Infected cells are cleared, and the virus is neutralised and eliminated from the body. As the infection subsides, symptoms gradually improve, and we begin to feel better and to recover. But recovery varies depending on the specific virus and us as individuals. Some respiratory viruses, like rhinoviruses which cause the common cold, may cause relatively mild symptoms and a quick recovery. Others, like the flu, SARS-CoV-2 or severe cases of RSV, may lead to more severe symptoms and a longer recovery time. Some viruses are very strong and too fast sometimes so that our immune system does not have the time to develop a proper immune response to fight them off. <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/207023/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lara-herrero-1166059">Lara Herrero</a>, Research Leader in Virology and Infectious Disease, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> and <a href="https://theconversation.com/profiles/wesley-freppel-1408971">Wesley Freppel</a>, Research Fellow, Institute for Glycomics, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Adorable reason behind Chris Hemsworth’s red carpet cheat notes

Chris Hemsworth has been married to Spanish actress Elsa Pataky for almost 13 years, and while she speaks fluent English, Hemsworth is yet to master her native tongue. On June 8, he was at the premiere of his Netflix film Extraction 2 and was caught with some Spanish words scrawled on the palm of his hand. The 39-year-old was then photographed with what appeared to be a cheat sheet, which he personally found hilarious. “After years of coming to Spain and being asked ‘has my Spanish improved’ I can safely say it’s in the palm of my hand,” he wrote on Instagram alongside the photo. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CtOqVmTJ1sx/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/CtOqVmTJ1sx/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Chris Hemsworth (@chrishemsworth)</a> </div> </blockquote> The actor revealed what was written on his hand during a guest appearance on local TV program El Hormiguero (Spanish for The Anthill). In the interview, Hemsworth also shared that his three children with Pataky - daughter India, 10, and twin sons Tristan and Sasha, 9 - find it funny that he doesn’t speak nor understand the language. “I try, but I can’t. My children laugh at me when I try to have a conversation with them in Spanish,” he admitted. “Sh*t, f**k, what happened? … I know that, that’s what my wife yells at me. The more she gets angry, the more she speaks Spanish.” Speaking to Today in 2017, Pataky said she had pretty much given up on teaching Hemsworth her native language, focusing on teaching their children instead. “He promised me, he said, ‘I’ll be speaking Spanish in two months.’ There we go, we have been together for six years,” Pataky – who speaks five languages: English, Spanish, Italian, French and Romanian - told Today. “That’s important, that’s what my mum did to me, talked in Romanian. I start to speak in English, I’m like, ‘I don’t express myself great.’ I got used to making an effort to speak to [the kids] in Spanish.” Image credit: Instagram

“Lunch-box-mum queen”: Woman goes viral over 2 ingredient cake mix

One Coles shopper has taken the internet by storm, revealing a “snack hack” with just two ingredients. Aussie mum-of-three Claudia creates content on TikTok on cheap Kmart buys, a day in the life of her family, and her most popular videos, her “snack hacks”. For her most recent hack, only two ingredients are required. “Snack hack! Again!” she said in the video, which has attracted more than 70,000 views on TikTok. “So, this one, I’m looking forward to. “This is not healthy. This is two ingredients — Nutella and eggs — and it’s supposed to make the gooiest, chocolatiest, yummiest cake ever. “I have not tried this before so let’s get to it.” Claudia didn’t have Nutella in her pantry, but she bought the Coles version, which she claims tastes very similar. “I’m a big believer in using what you have, but a few people said ‘check this out, make this, it’s delicious’ so I just had to,” she continued. “I did go and buy the Coles one, and it was very cheap, and I’m sure a lot of people do have Nutella in their cupboard.” For the snack hack, Claudia used one cup of the chocolate spread and four eggs to create a gooey cake mix. “If ‘trust the process’ had a cover photo, it would be this,” she said, visibly grossed out by the gooey batter. “It is safe to say I won’t be trying any of this cake mix.” Claudia instructed viewers to put the cake in the oven for 20-25 minutes at 180 degrees Celsius. “Do you know how good this smells?” she said as she took the cake tin out of the oven. She was even more excited by the time she tried it. “That is so good. So, so good. Like no exaggeration. So freaking good,” she said. People flooded the comments, applauding Claudia for another great “snack hack”. “I’m soooo trying this,” one person wrote. “Thank you, lunch-box-mum queen,” another added. “I honestly thought it was going to come out looking like chocolate scrambled eggs,” a third said. Claudia is renowned on TikTok for making snacks that are easy on household budgets, so people were grateful she used the cheaper Coles chocolate spread. “The Coles Nutella is just as good in my opinion,” one wrote.

"Makes us feel sick": Angry vegan slams meat-eating neighbours

A letter from a vegan neighbour has gone viral, as they asked a close-by resident to close their windows while they cook meat. The hand-written note was published on a community Facebook page for the Perth northern coastal suburb of Burns Beach, and was labelled as an "Important message" for the recipient to "Please take seriously". The note began, "Hello, neighbour." "Could you please shut your side window when cooking, please?" "My family are vegan (we eat only plant-based food), and the smell of the meat you cook makes us feel sick and upset." "We would appreciate your understanding." The letter went viral not long after it was posted, and drew in a range of divided comments. Some people believed the request was a ridiculous ask, with many people wondering where they draw the line when it comes to catering for others. "I'd understand if they were smoking cigarettes and the smoke and smell was spreading and affecting the family's health," one person wrote. "But not liking the smell of meat, this isn't really a good reason to ask someone to close their windows." "What does she do when she takes the kids to the park, and people are cooking BBQs? Ask them to stop cooking. Audacity." Others thought the request was reasonable, and praised the writer's politeness. "I feel like this was a genuinely polite letter, and it’s true the smell of meat is overpowering," one person wrote. "It would be nice to see some respect for your neighbours, and not publicly trying to shame them for holding strong ethical morals." Another put it simply, "Be vegan. Eat meat. Each to their own!" One commenter suggested the recipient resort to good old neighbourly pettiness, encouraging them to "Write back and say you're offended and sad by what they said about your cooking and could they please move to a different room as you would appreciate their understanding."

ChatGPT, DALL-E 2 and the collapse of the creative process

In 2022, OpenAI – one of the world’s leading artificial intelligence research laboratories – released the text generator <a href="https://chat.openai.com/chat">ChatGPT</a> and the image generator <a href="https://openai.com/dall-e-2/">DALL-E 2</a>. While both programs represent monumental leaps in natural language processing and image generation, they’ve also been met with apprehension. Some critics have <a href="https://www.theatlantic.com/technology/archive/2022/12/chatgpt-ai-writing-college-student-essays/672371/">eulogized the college essay</a>, while others have even <a href="https://www.nytimes.com/2022/09/02/technology/ai-artificial-intelligence-artists.html">proclaimed the death of art</a>. But to what extent does this technology really interfere with creativity? After all, for the technology to generate an image or essay, a human still has to describe the task to be completed. The better that description – the more accurate, the more detailed – the better the results. After a result is generated, some further human tweaking and feedback may be needed – touching up the art, editing the text or asking the technology to create a new draft in response to revised specifications. Even the DALL-E 2 art piece that recently won first prize in the Colorado State Fair’s digital arts competition <a href="https://www.smithsonianmag.com/smart-news/artificial-intelligence-art-wins-colorado-state-fair-180980703/">required a great deal of human “help”</a> – approximately 80 hours’ worth of tweaking and refining the descriptive task needed to produce the desired result. <blockquote class="twitter-tweet"> Today's moody <a href="https://twitter.com/hashtag/AIart?src=hash&ref_src=twsrc%5Etfw">#AIart</a> style is... 🖤 deep blacks ↘️ angular light 🧼 clean lines 🌅 long shadows More in thread, full prompts in [ALT] text! <a href="https://t.co/tUV0ZfQyYb">pic.twitter.com/tUV0ZfQyYb</a> — Guy Parsons (@GuyP) <a href="https://twitter.com/GuyP/status/1612539185214234624?ref_src=twsrc%5Etfw">January 9, 2023</a></blockquote> It could be argued that by being freed from the tedious execution of our ideas – by focusing on just having ideas and describing them well to a machine – people can let the technology do the dirty work and can spend more time inventing. But in our work as philosophers at <a href="https://www.umb.edu/ethics">the Applied Ethics Center at University of Massachusetts Boston</a>, we have written about <a href="https://doi.org/10.1515/mopp-2021-0026">the effects of AI on our everyday decision-making</a>, <a href="https://www.taylorfrancis.com/chapters/edit/10.4324/9780429470325-28/owning-future-work-alec-stubbs">the future of work</a> and <a href="https://doi.org/10.1007/s43681-022-00245-6">worker attitudes toward automation</a>. Leaving aside the very real ramifications of <a href="https://www.latimes.com/opinion/story/2022-12-21/artificial-intelligence-artists-stability-ai-digital-images">robots displacing artists who are already underpaid</a>, we believe that AI art devalues the act of artistic creation for both the artist and the public. <h2>Skill and practice become superfluous</h2> In our view, the desire to close the gap between ideation and execution is a chimera: There’s no separating ideas and execution. It is the work of making something real and working through its details that carries value, not simply that moment of imagining it. Artistic works are lauded not merely for the finished product, but for the struggle, the playful interaction and the skillful engagement with the artistic task, all of which carry the artist from the moment of inception to the end result. The focus on the idea and the framing of the artistic task amounts to <a href="https://theconversation.com/what-paul-mccartneys-the-lyrics-can-teach-us-about-harnessing-our-creativity-170987">the fetishization of the creative moment</a>. Novelists write and rewrite the chapters of their manuscripts. Comedians “write on stage” in response to the laughs and groans of their audience. Musicians tweak their work in response to a discordant melody as they compose a piece. In fact, the process of execution is a gift, allowing artists to become fully immersed in a task and a practice. It allows them to enter <a href="https://www.harpercollins.com/products/flow-mihaly-csikszentmihalyi?variant=32118048686114">what some psychologists call the “flow” state</a>, where they are wholly attuned to something that they are doing, unaware of the passage of time and momentarily freed from the boredom or anxieties of everyday life. This playful state is something that would be a shame to miss out on. <a href="https://www.press.uillinois.edu/books/?id=p073182">Play tends to be understood as an autotelic activity</a> – a term derived from the Greek words auto, meaning “self,” and telos meaning “goal” or “end.” As an autotelic activity, play is done for itself – it is self-contained and requires no external validation. For the artist, the process of artistic creation is an integral part, maybe even the greatest part, of their vocation. But there is no flow state, no playfulness, without engaging in skill and practice. And the point of ChatGPT and DALL-E is to make this stage superfluous. <h2>A cheapened experience for the viewer</h2> But what about the perspective of those experiencing the art? Does it really matter how the art is produced if the finished product elicits delight? We think that it does matter, particularly because the process of creation adds to the value of art for the people experiencing it as much as it does for the artists themselves. Part of the experience of art is knowing that human effort and labor has gone into the work. Flow states and playfulness notwithstanding, art is the result of skillful and rigorous expression of human capabilities. Recall <a href="https://www.youtube.com/watch?v=rUOlnvGpcbs">the famous scene</a> from the 1997 film “<a href="https://www.imdb.com/title/tt0119177/">Gattaca</a>,” in which a pianist plays a haunting piece. At the conclusion of his performance, he throws his gloves into the admiring audience, which sees that the pianist has 12 fingers. They now understand that he was genetically engineered to play the transcendent piece they just heard – and that he could not play it with the 10 fingers of a mere mortal. Does that realization retroactively change the experience of listening? Does it take away any of the awe? <a href="https://www.theatlantic.com/magazine/archive/2004/04/the-case-against-perfection/302927/">As the philosopher Michael Sandel notes</a>: Part of what gives art and athletic achievement its power is the process of witnessing natural gifts playing out. People enjoy and celebrate this talent because, in a fundamental way, it represents the paragon of human achievement – the amalgam of talent and work, human gifts and human sweat. <h2>Is it all doom and gloom?</h2> Might ChatGPT and DALL-E be worth keeping around? Perhaps. These technologies could serve as catalysts for creativity. It’s possible that the link between ideation and execution can be sustained if these AI applications are simply viewed as mechanisms for creative imagining – <a href="https://openai.com/blog/dall-e-2-extending-creativity/">what OpenAI calls</a> “extending creativity.” They can generate stimuli that allow artists to engage in more imaginative thinking about their own process of conceiving an art piece. Put differently, if ChatGPT and DALL-E are the end results of the artistic process, something meaningful will be lost. But if they are merely tools for fomenting creative thinking, this might be less of a concern. For example, a game designer could ask DALL-E to provide some images about what a Renaissance town with a steampunk twist might look like. A writer might ask about descriptors that capture how a restrained, shy person expresses surprise. Both creators could then incorporate these suggestions into their work. But in order for what they are doing to still count as art – in order for it to feel like art to the artists and to those taking in what they have made – the artists would still have to do the bulk of the artistic work themselves. Art requires makers to keep making. <h2>The warped incentives of the internet</h2> Even if AI systems are used as catalysts for creative imaging, we believe that people should be skeptical of what these systems are drawing from. It’s important to pay close attention to the incentives that underpin and reward artistic creation, particularly online. Consider the generation of AI art. These works draw on images and video that <a href="https://www.theguardian.com/technology/2022/nov/12/when-ai-can-make-art-what-does-it-mean-for-creativity-dall-e-midjourney">already exist</a> online. But the AI is not sophisticated enough – nor is it incentivized – to consider whether works evoke a sense of wonder, sadness, anxiety and so on. They are not capable of factoring in aesthetic considerations of novelty and cross-cultural influence. Rather, training ChatGPT and DALL-E on preexisting measurements of artistic success online will tend to replicate the dominant incentives of the internet’s largest platforms: <a href="https://doi.org/10.1111/josp.12489">grabbing and retaining attention</a> for the sake of data collection and user engagement. The catalyst for creative imagining therefore can easily become subject to an addictiveness and attention-seeking imperative rather than more transcendent artistic values. It’s possible that artificial intelligence is at a precipice, one that evokes a sense of “<a href="https://www.theatlantic.com/magazine/archive/2004/04/the-case-against-perfection/302927/">moral vertigo</a>” – the uneasy dizziness people feel when scientific and technological developments outpace moral understanding. Such vertigo can lead to apathy and detachment from creative expression. If human labor is removed from the process, what value does creative expression hold? Or perhaps, having opened Pandora’s box, this is an indispensable opportunity for humanity to reassert the value of art – and to push back against a technology that may prevent many real human artists from thriving.

James Cameron caught giving fans the bird after being booed

Legendary director James Cameron has been caught flipping off the fans who booed him for not signing autographs over the weekend. After the famed director attended a screening of his new film, Avatar: The Way of Water, in LA, he refused to stop for a crowd of autograph-seeking fans. Cameron, 68, powered past the group of people asking him to sign their items, which caused the crowd to turn on him and shout. “F**k Avatar,” one person yelled, as Cameron was escorted into a black car. As the cheering and jeering continued, the Titanic filmmaker slightly rolled down his tinted window to reveal his middle finger. Fans were divided over the interaction, with some calling him a “jerk” and “annoying.” Others dubbed him “a legend” and argued that the people booing him weren’t real fans. “They were fake fans ready to resell autographed stuff 100%. The embarrassing way they reacted to his refusal proves that. Jim was right for ignoring them let’s be serious,” one person wrote on Twitter. Check out the footage and see for yourself. <blockquote class="twitter-tweet"> James Cameron flips off crowd who boos him for not signing autographs <a href="https://twitter.com/hashtag/AvatarTheWayOfWater?src=hash&ref_src=twsrc%5Etfw">#AvatarTheWayOfWater</a> <a href="https://t.co/frDDoY4alM">pic.twitter.com/frDDoY4alM</a> — Culture Crave 🍿 (@CultureCrave) <a href="https://twitter.com/CultureCrave/status/1604621184611471360?ref_src=twsrc%5Etfw">December 18, 2022</a></blockquote> Images: Twitter

Is just 4.5 kg of weight loss really going to help stop type 2 diabetes?

A new study has found that losing just 4.5 kg of weight could be the difference between getting type 2 diabetes and not. That’s the headline on some of the publicity surrounding the research, except like all these studies, it’s significantly more complicated than that. So, let’s talk about it. The study looked at around 100,000 nurses and other health professionals from a few different US cohort studies that started in the late 1980s. The team looked at up to 10 years of weight changes and tracked the participants for 24 years to see if they developed type 2 diabetes. They also looked at the way that those who lost more than 4.5 kg, dieted. They split them into seven categories – low-calorie diet; exercise; low-calorie diet plus exercise; fasting; commercial weight loss program; diet pills; and a combination of fasting, commercial and diet pills. When the team looked at the original results, they found something surprising: In the overall population, those who lost more than 4.5 kilograms had a higher risk of being diagnosed with type 2 diabetes than those that didn’t diet or try and lose weight. This was particularly striking for those that lost the weight due to limiting calories, diet pills, fasting, or weight loss programs. The researchers then split the data into BMI categories – those who were ‘normal’ weight or underweight, those who were overweight and those who were obese. The findings of a higher risk of type 2 diabetes after trying to lose weight broadly held in both the ‘underweight’ and ‘normal’ as well as the ‘overweight’ categories. “We were a bit surprised when we first saw the positive associations of weight loss attempts with faster weight gain and higher type 2 diabetes risk among lean individuals,” says Qi Sun, a nutrition researcher at the TH Chan Harvard School of Public Health. As you can see in this figure below, the risk of type 2 diabetes only reduced a little – significantly less than the increased risk of type 2 diabetes if you lost over 4.5 kilograms while at a normal BMI. <img src="https://oversixtydev.blob.core.windows.net/media/2022/10/figures.jpg" alt="" width="1280" height="720" /> As noted in the paper, the vast majority of people try and diet at some point or another – in 2013 to 2016 almost half of US adults reported trying to lose weight. But almost everyone either doesn’t succeed or puts all the weight back on, normally within a few months. This study backs that up. After 10 years, those who tried to lose weight (known as the weight loss strategies group) gained more weight than those that hadn’t. “Participants who lost 4.5+ kg were likely to gain more weight and have higher risk of type 2 diabetes than those who did not attempt to lose weight,” the team writes in their paper. “By 10 years of follow-up, all weight loss strategy groups were associated with more weight gain than the reference group (ranging from 1.7% for exercise to 6.6% for fasting, commercial weight loss program and pills).” It’s important to note here that exercise and eating well is not bad for you. Exercise has been shown time and time again to help us live longer, and eating more fruits and vegetables and less processed food is better for us. However, this study is a good reminder that just losing weight – particularly in ways like weight loss pills, calorie restriction and weight loss programs are not a silver bullet for keeping us healthy. In fact, depending on who you are, it seems it might make it worse. The conclusion from the study is worth reading in full: In conclusion, in individuals with obesity, losing 4.5+ kg of body weight intentionally was associated with less weight gain and lower T2D risk, regardless of the methods used to achieve the weight loss. However, for individuals who were lean, losing 4.5+ kg was not associated with these health benefits. Of all WLSs, exercise was optimal for long-term weight control and T2D prevention. Our data support current guidelines for body weight management, such as that issued by the Obesity Society, which recommend a weight loss of 5% to 10% of baseline weight for individuals who are overweight or obese and exercise of 200 to 300 minutes per week to maintain the weight loss.

Cats declared an “invasive alien species” in Poland

A scientific institute in Poland has categorised domestic cats as an “invasive alien species”, joining a menagerie of animals on their invasive species list. The Polish Academy of Sciences has deemed the house cat (Felis catus) as an “alien” species as it was domesticated in the Middle East, and “invasive” due to the “negative influence of domestic cats on native biodiversity”, according to a statement. Cats join a long list of animals and plants deemed an “invasive alien species” by the institute, including Japanese knotweed, racoons, clearwing moths and mandarin ducks. The Academy states that cats pose “an unpredictable risk to local wildlife”, citing <a href="https://www.sciencedirect.com/science/article/pii/S2351989418303196?via%3Dihub" target="_blank" rel="noopener">a study</a> that shows cats kill 41.1 million mammals and 8.9 million birds each year, eating an additional 583.4 million mammals and 135.7 birds. Wojciech Solarz, a biologist at the state-run institute, told <a href="https://apnews.com/article/science-poland-wildlife-cats-birds-b942a55135832d085375de73c9cc2e23?user_email=d892765ed707c6b27af3429c2e8ec0607119ec5a15758542d760a9bac7b882a8&utm_source=Sailthru&utm_medium=email&utm_campaign=July27_MorningWire&utm_term=Morning%20Wire%20Subscribers" target="_blank" rel="noopener">AP</a> that the criteria to be declared an alien invasive species “are 100 percent met by the cat”. However, cat owners and lovers have expressed outrage at the decision, arguing it could incite abuse or mistreatment of cats, with concerned commenters declaring it “simply stupid and harmful” on the Academy’s Facebook page. AP has also reported that some media reports have incorrectly given the impression that the Academy was calling for cats to be euthanized. Solarz told the outlet he hadn’t expected such a response, adding that no other entry on their database of invasive and alien species had resulted in such an emotional response. He suggested that the negative feedback may be due to a misunderstanding that the Academy was implying that people harm their cats. In actuality, the Academy has only recommended that cat owners limit the amount of time their pets spend outdoors during bird breeding season. Images: Getty Images

(H)anger is real: your bad mood and empty stomach are linked

<div class="copy"> Grumpy? Long time between meals? Well now you can cheer up, thanks to a new study validating the link between your cranky mood and grumbly belly – your ‘hanger’ is real. Psychologists studying a group of primarily Austrian, German and Swiss adults have found an association between self-reported hunger, and heightened levels of anger and irritability. Helping people understand their own emotional responses to feelings of hunger could help them better regulate their behaviour, says Anglia Ruskin University professor in social psychology Viren Swami. “Research suggests that being able to label an emotion can help people to regulate it,” says Swami, who was the lead author of the study <a href="https://doi.org/10.1371/journal.pone.0269629" target="_blank" rel="noreferrer noopener">published</a> in Plos One. “Therefore, greater awareness of being ‘hangry’ could reduce the likelihood that hunger results in negative emotions and behaviours in individuals.” The three-week study monitored 64 participants who submitted five daily reports to researchers via a smartphone app. In each report, participants used a 0–100 scale to evaluate how hungry, irritable and angry they felt. Even when accounting for demographic differences between participants, there was an association between hunger and heightened levels of irritability, anger and reduced feelings of pleasure. It’s the first time the phenomenon has been investigated outside of a laboratory environment and adds to an existing body of research showing that declines in blood glucose levels influences negative emotions. “This ‘hangry’ effect hasn’t been analysed in detail, so we chose a field-based approach where participants were invited to respond to prompts,” explains study co-author Stefan Stieger, professor of psychology at Karl Landsteiner University. “[It gives] a much more complete picture of how people experience the emotional outcomes of hunger in their everyday lives.” The researchers didn’t offer conclusions as to how to mitigate hunger-induced feelings. Reaching for a banana next time you feel cross is probably a safe bet.

This $2 fix will save your feet next time you wear heels

Heels might make us look great and feel confident, but they can come at a cost to our hardworking feet, namely aches, pains, and even blisters. Rachel Clinkard, who works at family-run shoe retailer Charles Clinkard, is all too familiar with this situation - and she’s got an easy fix she swears works wonders. She says that all you need is a $2 roll-on deodorant, as reported by <a href="https://www.mirror.co.uk/news/weird-news/bargain-29p-hack-stop-your-27221303" target="_blank" rel="noopener">The Mirror</a>. Clinkard claims that by applying some deodorant to the areas of your feet you think will rub while in heels, it will create a barrier between your skin and the shoe and help to prevent chafing. This hack can replace bandaids, plasters and other products like gel inserts. With deodorant going a long way, each application will be significantly cheaper than many of the alternatives too. Plus they smell great too! Image: Getty Images

Bitter groom sells ex-fiancée’s dress in angry post

A bitter groom selling his ex-fiancée’s wedding dress has been called out for his nastiness in the ad in which he claims she cheated on him. Photos of the wedding dress were shared to Facebook Marketplace for just £5 ($A9) in which he then claimed he had a lucky escape. He labelled the dress size as “size fat” before giving viewers an idea of why the wedding was called off. “Wedding dress – would fit the larger lady, quite chavvy in style so would suit a cheap sl**per,” he wrote. “It’s a size 12 I think – she was prone to lying so it’s possibly a 14/16.” Within the post, he accused his ex of cheating on him and he just wanted to get rid of the dress. Viewers however sided with the bride, claiming she was the one who had a lucky escape from his disgusting comments. “Somehow I think it’s she who had the lucky escape,” one wrote. “This says more about him than it does her,” someone said. “I think it's a beautiful dress. She's probably the lucky one to get out of the relationship,” another commented. There were a few people who sided with the groom who said he was probably venting after getting hurt. “Everyone thinking she had a lucky escape when it sounds like he was cheated on. Who hasn’t said crap about an ex,” one wrote. “Maybe she broke his heart and he’s venting?” asked another. “All the ‘she’s had a lucky escape’ comments but if it was a girl trashing a guy’s car they’d all be hyping her up! Double standards,” another added. Images: TikTok

"I have one no one came around to and I'm still embarrassed I was in,” Bullock confessed to <a href="https://toofab.com/2022/03/21/sandra-bullock-daniel-radcliffe-the-lost-city-interview/" target="_blank" rel="noopener">TooFab</a>. “It's called 'Speed 2.' I've been very vocal about it. Makes no sense. Slow boat. Slowly going towards an island. “That’s one I wished I hadn’t done, and no fans came around that I know of.” Keanu Reeves, her on-screen lover in Speed, did not star in the sequel, instead Bullock was cast with Jason Patric. Reeves previously said that after reading the script to Speed 2 that he “decided not to be in it”. Bullock’s new movie The Lost City will be released on 14 April 2022. Image: Instagram

"I'm so angry": Man fumes after threatened with fine for sleeping in his van

A Queensland man has taken to social media to share his fury at the local council after he was issued a move-on directive while sleeping in his van.Mark Pemberton shared his story on the Facebook page Van Life Australia, recounting how council workers shone a torch into the window of his van which was parked on a suburban street.“I’m so angry,” he wrote.“Last night (Tuesday) I parked in a very quiet spot at around 8pm. (Gold Coast) 10.50pm, council came around and knock (sic) on the door.“They were very nice, but told me it was a $680 fine for sleeping in the street in a van and I had to move.”He then questioned why he had been approached while countless other people who were sleeping rough in Surfers Paradise were left alone by Gold Coast Council workers.“Now the thing is, I live in a unit in Surfers Paradise. I was in the van for various reasons,” he continued.<img src="https://oversixtydev.blob.core.windows.net/media/2022/02/53992333-10492397-His_Facebook_post_on_the_page_Van_Life_generated_plenty_of_discu-m-1_1644461096527.jpg" alt="" width="634" height="476" />Image: Daily Mail Australia“I see the homeless drunk, swearing, begging and sleeping in the street on a daily basis in the middle of Surfers.“I also see a guy who I won’t name, but is semi-famous and walks around in a bikini, sleeps in the street cuddling a teddy.”Mr Pemberton questioned why the council thought it was acceptable to let that individual walk around in public in front of kids, when he wasn’t allowed to sleep “down a dark street in a registered vehicle”.“This is ridiculous. This is not about an individual, this is about the stupidity of the Council,” he concluded.Though his post generated plenty of discussion, it has since been deleted by page administrators.The former business executive who once earned a $200,000 salary is now unemployed, with the pandemic and other personal circumstances seeing him “lose everything”.“My van is registered and roadworthy and was also legally parked on a street in Paradise Point,” he told <a href="https://www.dailymail.co.uk/news/article-10492397/How-fined-sleeping-car-Australia.html" target="_blank" rel="noopener">Daily Mail Australia</a>.He recalled being almost asleep when two council workers shone a torch into his van. “I explained my situation and I will say they were sympathetic, but I was told I had to move on elsewhere,” he told the publication.“I understand they are doing their job, but surely the council could focus on other issues at hand?”<img src="https://oversixtydev.blob.core.windows.net/media/2022/02/217397376_1146034059251748_5444362758567874310_n.jpg" alt="" width="652" height="960" />Mark Pemberton was inspired to take up living the van life after his travels through Europe. Image: Herc the Merc (Facebook)Mr Pemberton said the council should focus on addressing issues such as “homelessness and mental health”, rather than “people minding their own business in a registered van”.Having lived out of a van during his previous travels through Europe, Mr Pemberton is convinced it is the lifestyle for him.“After my personal dramas, van life was great for mental health,” he said.“I understand it isn’t for everyone, but in my eyes it is a great opportunity to see the world differently.”Image: Mark J Pemberton (Facebook)

TikTok shows bird inside cabin on flight from Europe to US

A passenger on a flight from Europe to the US has shared a video of a bird that was trapped inside the cabin during her flight. Brooke Frazier uploaded a video to TikTok of a bird flying throughout the cabin of the plane she was on, writing, "Bird stuck on our eight hour flight from Europe lil guy about to be so confused.” In the caption, she wrote that the bird had “hopped on” the flight in Belgium and was “going crazy” during the flight to the US. <div class="embed"><iframe class="embedly-embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7051627241830403374&display_name=tiktok&url=https%3A%2F%2Fwww.tiktok.com%2F%40totallychillfemale%2Fvideo%2F7051627241830403374&image=https%3A%2F%2Fp16-sign.tiktokcdn-us.com%2Ftos-useast5-p-0068-tx%2F7dd3104a4c624e7ebda67ae7affa603c_1641834912%7Etplv-tiktok-play.jpeg%3Fx-expires%3D1642078800%26x-signature%3D26FoJY0C1LvfiLhbFiJa3bTZQBc%253D&key=59e3ae3acaa649a5a98672932445e203&type=text%2Fhtml&schema=tiktok" width="340" height="700" scrolling="no" title="tiktok embed" frameborder="0" allow="autoplay; fullscreen" allowfullscreen="true"></iframe></div> The video has received almost 12 million views, almost 2 million likes, and over 20,000 comments. Commenters were quick to see the humour in the situation, with one suggesting it was something out of a movie, writing, “Pixar movie. European bird runs away cuz all his family bullied him for being small. now he's raised by a bunch of pigeons from Jersey”. Brooke herself responded with her own movie synopsis, saying, “migrant bird opens a bakery in jersey to show his pursuit of the american dream while going back to his roots with family recipes”. Another commented “Omg I hope he speaks English,” while another said, “He’s gonna have to learn to fly on the right side.” Brooke posted a followup video once they’d touched down, asking, “Does anyone know if Pfizer protects against bird flu?” Many users wanted more information on the bird’s fate, with one person writing, “They should provide a free return trip for him”, while another said, “It’s gonna be so lonely without its friends”. Brooke herself commented, “I started tearing up bc it's whole family is in Belgium and it's gonna get off and have to make new friends." Image: TikTok

“No right to be here”: Angry tennis stars pile on as Novak issues new statement

Novak Djokovic continues to face harsh criticism from commentators, fans, and fellow tennis players as more details about his behaviour in the lead-up to his arrival in Australia emerge. The Serbian tennis star posted a statement on Instagram on Wednesday afternoon, in which he clarifies when he tested positive for COVID-19, and admits that he attended an in-person interview and photoshoot on December 18 while knowingly positive for the virus. He explained that he did this as he “didn’t want to let the journalist down”, but he made sure he “socially distanced and wore a mask” except for when his photo was being taken. He added that upon reflection, he realises this was an error of judgement. <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" class="instagram-media" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CYnO7cDqbdj/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"></div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"></div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"></div> </div> </div> <div style="padding: 19% 0;"></div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"></div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" rel="noopener" href="https://www.instagram.com/p/CYnO7cDqbdj/?utm_source=ig_embed&utm_campaign=loading" target="_blank">A post shared by Novak Djokovic (@djokernole)</a> </div> </blockquote> He also explained that his travel declaration was submitted by his team on his behalf, and his agent has sincerely apologised for the administrative error in ticking the box about his previous travel before arriving in Australia that saw him detained last week. Meanwhile, his fellow tennis players have voiced concerns about his actions, with former world number 1 Andy Murray suggesting there are “a few questions to be answered” and urging Djokovic to come clean. Murray had just won his first match in Australia in three years when he was asked about Djokovic, and he told reporters, “I mean, obviously, it‘s positive that he’s not in detention anymore. Obviously, he won in court, so that‘s a positive thing for him. Hopefully, (he) will be able to concentrate on the tennis now. “There are still a few questions that need to be answered around the isolation and stuff, which I‘m sure we’ll hear from him in the next few days, but I’m obviously here to try and play and win tournaments. “Like I said, it’s the first match that I have played here or won here in over three years, and this is where the situations like this are frustrating for players because I want to come off and talk about my tennis and what’s happening there, not talking about situations like that. So I‘m hoping that we can move on from it now. “He won in court, which is good. Looks like he’s going to be able to play and compete in the Australian Open, which we do want the best players there, but like I said, I think there is still a few questions to be answered. Until that happens, tough to give a definitive opinion on everything. But like I said, positive that he‘s out and practising.” Portuguese player Joao Sousa was critical of Djokovic’s attempt to skirt the rules. He told reporters, “I respect that he fights for what he believes and I can be empathetic with what he is going through in Australia, but it’s a bit selfish from him to arrive here as the only player unvaccinated. It’s tough for us players to accept that. “Many players — not my case — didn’t want to get vaccinated and were forced to do it to be able to play tournaments. He is finding a way around those rules.” Marton Fucsovics also criticised Djokovic, saying, “People’s health is paramount, and there are rules that were outlined months ago, namely that everyone should vaccinate themselves — and Djokovic didn’t. From this point of view, I don’t think he would have the right to be here.” Image: Michael Dodge/Getty Images

Garden birds are struggling: four ways to help

More than a quarter of Britain’s birds are now on the RSPB’s <a rel="noopener" href="https://www.rspb.org.uk/birds-and-wildlife/wildlife-guides/uk-conservation-status-explained/" target="_blank">red list</a>, meaning that their numbers are in severe decline. Some of the recent additions to the red list are thought of as common garden birds, such as the greenfinch. Others, such as the swift and house martin, only spend spring and summer visiting the UK before migrating to warmer climes. But the environment they encounter in the UK, as well as along their migration routes, affects their survival significantly. Many of the species that we feed in our gardens and on balconies are under threat. Here are four ways to help them. 1. Clean your bird feeders and bird baths In the wild, with a few exceptions such as starlings, birds don’t come into close contact with each other much. This lack of contact makes it harder for diseases to spread. Bird feeders change this dynamic. The presence of a bird feeder means that many individual birds from many different species feed in the same area. This leads to the <a rel="noopener" href="https://www.bto.org/community/news/201803-feed-birds-scientists-highlight-risks-disease-garden-bird-feeders" target="_blank">spread of disease</a>, because birds often poo where they eat, leaving pathogens to infect the next visitor. <img src="https://images.theconversation.com/files/438076/original/file-20211216-23-13tbwiw.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Two birds on a house shaped feeder" /> Greenfinches on a bird feeder. <a rel="noopener" href="https://www.shutterstock.com/image-photo/greenfinches-perching-on-bird-feeder-spring-1667803654" target="_blank" class="source">Chamois huntress/Shutterstock</a> The greenfinch, a once common garden bird now added to the red list, has suffered because of this. The disease <a rel="noopener" href="https://www.bto.org/our-science/projects/gbw/gardens-wildlife/garden-birds/disease/trichomonosis" target="_blank">trichomonosis</a>, which used to just infect pigeons and doves, has spread to greenfinches with deadly consequences. Regular cleaning of your garden bird feeders and bird baths can reduce this risk. 2. Install bird nesting boxes Many people help birds by putting up nest boxes in their gardens. But these boxes are mostly made for robins and tits who nest in open boxes, or ones with small holes. These nest boxes mimic the crevices and holes that would be available in mature trees. Swifts and house martins are new entrants to the red list, and both of these will readily use man-made nesting places if we provide them – with a few modifications for their needs. House martins will nest in a pre-made or home-made <a rel="noopener" href="https://www.rspb.org.uk/birds-and-wildlife/advice/how-you-can-help-birds/nestboxes/how-to-attract-house-martins/" target="_blank">nest cup</a> which mimics the mud nests house martins make for themselves. Swifts will <a rel="noopener" href="http://www.saveourswifts.co.uk/attractswifts.htm" target="_blank">nest in boxes</a>, but they take a bit more work to attract. The best way to do this is to play their screeching call from a speaker placed close to the nest box, to get them to investigate and hopefully nest. You can make nest boxes attractive to these species by installing them in the eaves of your home, as they need them to be up high so they can take flight from them easily. 3. Add some insect-friendly plants Many of the species entering the red list, such as the house martin and house sparrow, feed on insects. Insects numbers have <a rel="noopener" href="https://www.nhm.ac.uk/discover/news/2019/february/the-world-s-insect-populations-are-plummeting-everywhere-we-look.html" target="_blank">declined rapidly</a>, so it is no surprise that these avian predators are finding it hard to feed themselves and their chicks. You may love a neat and tidy garden or balcony, but set aside an area to be a bit messier and weedier to attract insects. Adding <a rel="noopener" href="https://www.rhs.org.uk/science/conservation-biodiversity/wildlife/plants-for-pollinators" target="_blank">pollinator-friendly plants</a>, such as lavender, foxglove and sedum, could really boost insect numbers – natural bird food – in your garden. 4. Reduce dangers to birds <a rel="noopener" href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0049369" target="_blank">Pet cats are predators</a> and can target species like house sparrows, which remain on the red list. Even the presence of cats could be enough to <a rel="noopener" href="https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2664.12025" target="_blank">scare birds</a>, reducing the number of young they may be able to have. This may have a more damaging impact on bird populations than the number of birds killed by cats. <img src="https://images.theconversation.com/files/438077/original/file-20211216-17-10dzdgj.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" alt="Cat stalking along fence under roses" /> Cats are predators and their presence affects bird populations. <a rel="noopener" href="https://www.shutterstock.com/image-photo/cat-burglar-front-roses-on-prowl-1503499694" target="_blank" class="source">Lilly P. Green/Shutterstock</a> If you own a cat, there are ways for you to reduce its effect on bird numbers. A collar with a bell is an effective way to warn birds and other animals about a cat’s presence. In addition, you could consider restricting when cats are allowed outside to just the daytime, as birds can be more vulnerable in the very early morning when they wake and start to look for food. Alternatively, you could keep cats inside entirely. It is very common in Australia and the US for cats to remain indoors. These changes may seem small and your garden or outdoor space may not be big, but gardens in the UK <a rel="noopener" href="https://www.wildlifetrusts.org/habitats/towns-and-gardens" target="_blank">cover more area</a> that all of our nature reserves put together. Encouraging wildlife in these garden habitats can make a big difference.<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; text-shadow: none !important;" src="https://counter.theconversation.com/content/173025/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a rel="noopener" href="https://theconversation.com/profiles/becky-thomas-506528" target="_blank">Becky Thomas</a>, Senior Teaching Fellow in Ecology, <a rel="noopener" href="https://theconversation.com/institutions/royal-holloway-university-of-london-795" target="_blank">Royal Holloway University of London</a> This article is republished from <a rel="noopener" href="https://theconversation.com" target="_blank">The Conversation</a> under a Creative Commons license.
