Could bats hold the secret to beating Covid and cancer?
Bats could hold the key to unlocking new ways to combat cancer, a new study suggests. A paper published by Oxford University Press, looks at the rapid evolution of bats for their abilities to both host and survive infections such as Covid-19 as well as cancer. The animals are known to have a strong immune system which helps fight off many viruses and diseases. These mammals are also thought to have played a role in the emergence of Covid-19 and scientists say such characteristics are interesting to investigate due to the implications it might have on human health. According to the research, understanding the mechanisms of the bat’s immune system that allows these animals to fight off viral infections – may pave the way to understanding how to prevent disease outbreaks from animals to people. To conduct the study, researchers sequenced the genomes of two bat species - the Jamaican fruit bat and the Mesoamerican mustached bat. The team used advanced technology from Oxford Nanopore Technologies and bat samples collected by the American Museum of Natural History in Belize. They then compared the bat genomes to those of other mammals. The results revealed that bats possessed genetic adaptations in proteins which are related to DNA repair and cancer suppression. It was found that bats had adaptations in six DNA repair-related proteins and 46 cancer-related proteins. The study also found that bats had more than double the number of altered cancer-related genes compared to other mammals, which provided further evidence that they have the ability to suppress cancer. “By generating these new bat genomes and comparing them to other mammals we continue to find extraordinary new adaptations in antiviral and anticancer genes,” said the paper’s lead author, Armin Scheben. “These investigations are the first step towards translating research on the unique biology of bats into insights relevant to understanding and treating ageing and diseases, such as cancer, in humans.” The results open up new paths for understanding and studying the links between cancer and immunity, which offers hope that these insights from bats might possibly lead to new treatments for human illnesses. According to the United States Department of the Interior, there are over 1,400 species of bats worldwide and are mostly found in extreme deserts and polar regions. In the US and Canada, there are about 45 species of bats.

Influencers called out after promoting Shein factory in China
A group of influencers have come under fire after posting glowing videos from their paid trip to a factory owned by controversial fast fashion retailer Shein in Guangzhou, China. Shein, which has been previously accused of labour abuse and admitted to breaching rules around working hours, brought the group of six fashion influencers from the US to tour its “Innovation Factory”. Influencer and model Dani Carbonari was one of the influencers who went on the trip and posted a video tour on her social media last week. After facing criticism from her followers – of which she was more than 481k on Instagram and nearly 300k on TikTok – Carbonari appears to have deleted the post. In her original post, she wrote in her caption that the trip to Shein’s factory gave her the opportunity to see with her “own two eyes what the entire process of Shein clothing looks like from beginning to end”. “I feel more confident than ever with my partnership with Shein. There are so many companies not taking half the initiative Shein is. They are aware of every single rumour and instead of staying quiet they are fighting with all of their power to not only show us the truth but continue to improve and be the best they can possibly be,” the “confidence activist” continued. The video showed a brightly lit factory, with staff working in clean, dust-free conditions and automated bots that assisted with processing and packaging orders. The other influencers, Destene Sudduth, Aujene, Fernanda Stephany Campuzano, Kenya Freeman, and Marina Saavedra, also shared similarly glowing Instagram posts about their visit. Viewers have pointed out that the influencers appeared to use a “script” for their posts, as they involved similar language. In her post, Saavedra said: “Like many others, I’ve heard a lot of misinformation”, while Carbonari wrote: “You have to remember our country is filled with so much prejudice – we want to believe we’re the best and no one else can be better.” @shein_us Get a glimpse of the process of how your purchases are packaged directly from our facility and delivered to your doorstep.

Channel 4 launched an investigation last year that involved an undercover worker filming inside two Shein factories in Guangzhou and found that workers receive a base salary of 4k yuan per month (approximately £434) to produce 500 pieces of clothing per day. The investigation also found that workers in both factories were working up to 18-hour days regularly and were only given one day off a month. Later, Shein said that after conducting an independent investigation, it found that employees indeed working longer hours than the local laws allowed. Shein found that staff at one factory were working up to 13-and-a-half hour days with two to three days off a month, while those at the second site worked up to 12-and-a-half hour days with no fixed structure for days off. It said that “while these are significantly less than claimed in the documentary, they are still higher than local regulations permit”. At the time, Shein vowed to invest US$15m (£11.8m) to improve standards at its supplier factories. On Twitter, one person wrote: “Shein is sending the influencer girlies to China to some (PR) ‘innovation’ factory where it looks pristine and super clean and the workers are having fun while sewing and the company saying they pay a ‘competitive’ wage lol.” Another said: “The funniest part of the Shein debacle to me is the influencers acting like they went undercover to investigate. You were invited, of course, it’s PR.” A third added: “Them Shein influencers getting cooked and Shein ain’t [sic] defending them. Meanwhile the girls are doing their best to explain to us why Shein ain’t too bad. It’s sad.” The Independent has contacted Shein, Carbonari, Sudduth, Aujene, Campunazo, Freeman and Saavedra for comment.

9 arthritis myths we all need to stop believing
Many people assume arthritis is just an ‘old person’s’ disease, and an inevitable part of getting older. Try telling that to the parents of toddlers impacted by the condition, or the 20-somethings living with it. The suggestion that it only troubles the elderly is one of many myths associated with arthritis, which affects around 10 million people in the UK. “One in six people live with the pain, fatigue, and disability arthritis can cause. The impact can be huge, affecting the ability to work, care for family, move free from pain and live independently,” says Deborah Alsina, chief executive at the arthritis support charity Versus Arthritis, speaking to mark Rheumatoid Arthritis Awareness Week (September 11–17). “There are many misconceptions when it comes to understanding arthritis, but by shining a light on the reality of living with arthritis day in, day out, we can help grow understanding and inspire people to take action.” Dr Amara Ezeonyeji, consultant rheumatologist from The Lister Hospital in London (part of HCA Healthcare UK), adds: “Arthritis is a general term that refers to a group of over 100 different types of inflammatory joint diseases that affect the musculoskeletal system. The most common symptom of arthritis is joint pain, but it can also cause stiffness, swelling, and decreased joint mobility.” She says the most common form of arthritis is osteoarthritis (OA), often associated with wear and tear of the joints. Other common types are rheumatoid arthritis (RA), an autoimmune disease that primarily affects the joints; psoriatic arthritis, a type of arthritis associated with the skin condition psoriasis; ankylosing spondylitis which primarily affects the spine and can lead to fusion of the vertebrae; and gout, which is caused by the accumulation of uric acid crystals in the joints and often affects the big toe. “There are several myths about arthritis that are often repeated. It’s important to dispel these to promote an accurate understanding of arthritis, and to encourage those affected to seek appropriate medical care and support from a rheumatologist,” Ezeonyeji adds. Here, Alsina and Ezeonyeji debunk nine common arthritis myths… Myth 1: Arthritis only affects the elderly While it is more common in older adults, arthritis can affect people of all ages, including children and young adults. Myth 2: Cracking your knuckles causes arthritisPeople who crack their knuckles will sometimes be wrongly warned that it’ll bring on arthritis, but Ezeonyeji explains: “There’s no scientific evidence linking knuckle cracking to the development of arthritis. When people crack their knuckles, they experience a release of pressure in the joints and relaxation in the surrounding muscles. It can make the joint feel more mobile and is unlikely to cause arthritis or other problems.” Myth 3: It’s just wear and tearAlsina says one of the most damaging myths is that any form of arthritis is just ‘wear and tear’. “Osteoarthritis is the most common type of arthritis and will affect half of us by age 70. But it isn’t an inevitable part of ageing – your joints are not like car tyres destined to wear down and be replaced. They are made of complex living tissue that our bodies constantly repair and maintain, and osteoarthritis occurs when our bodies can no longer do this effectively,” she says. “Our joints get stronger the more we use them, so keeping physically active and maintaining a healthy weight can help keep osteoarthritis under control.” Myth 4: Cold damp weather causes arthritisAlthough cold and damp weather can sometimes make arthritic joints feel worse, it’s definitely not why arthritis starts. Ezeonyeji explains: “Weather can influence joint discomfort, but it doesn’t cause arthritis. Arthritis is primarily a result of genetic and environmental factors.” Myth 5: Exercise makes arthritis worse People with arthritis can often find it hard to maintain regular physical activity, but a lack of movement can actually increase symptoms such as stiffness and pain, warns Alsina. “Building activity into your daily routine can help improve this, because using your joints builds muscle strength and improves the blood supply, all of which can ease symptoms and keep joints in better shape for longer.” She says different activities will suit different people, but adds: “Swimming and cycling are great exercises to try, as they get the body moving without putting pressure on painful joints.” It’s always a good idea to seek advice from a healthcare specialist if you are unsure what types of exercise will be suitable for you. Myth 6: Arthritis is just joint pain – it’s not serious Ezeonyeji says that while arthritis can be debilitating and lead to a reduced quality of life, it can get even more serious than that for some people. “Rheumatoid arthritis, for instance, is an autoimmune disease that can affect various organs and tissues in addition to joints,” she points out. Myth 7: There’s no treatment for arthritis While there’s no cure for arthritis, Ezeonyeji says there are many effective treatments for managing the disease, including pain relief medication, physiotherapy, disease modifying agents and biological drugs for inflammatory arthritis, plus joint surgery in some cases. “It’s also recommended that people with arthritis modify their lifestyle and try to lose weight [if they need to], follow a healthy balanced diet, exercise regularly and stop smoking,” she adds. Myth 8: Miracle cures can make arthritis disappear Although some people with arthritis believe copper or magnetic bracelets ease symptoms, Alsina says studies show no evidence to support this. “It’s the same with lots of supplements, and some of these are really pricey,” she observes. “Interestingly though, placebos can be very effective and continue to work even if you know it’s a placebo, so if you find these helpful there’s no reason to stop.” Myth 9: Certain foods definitely help/hinder arthritisThere are claims that foods like tomatoes can cause arthritis flares, and other foodstuff like cider vinegar may help it. Alsina says: “Sadly there’s no good evidence that there are specific foods you should avoid or have more of. But if you do find things that are helpful or make your symptoms worse, then listen to your body.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Prince Harry spotted at Windsor Castle on anniversary of Queen’s death How the weather can change the way you dream All the times Kate has channelled the late Queen’s style since her death
