Researchers make concerning discovery after examining blood samples from birds: 'We need to find out more about the sources'
As we gain more knowledge about the substances that make up our world, it gets easier to identify toxins that damage humans and wildlife. Unfortunately, we're finding these harmful substances in unexpected places and quantities, with negative impacts on our long-term health. One recent study, reported by Norwegian SciTech News, revealed that harmful PFAS are found in higher concentrations than we ever knew in China's birds — and the implications stretch worldwide. Researchers from the Norwegian University of Science and Technology examined blood and liver samples from Chinese wading birds as well as shellfish from the areas where the birds feed. They were looking for perfluoroalkyl and polyfluoroalkyl substances, better known as "forever chemicals" because they take up to 1,000 years to break down naturally. The researchers already knew they would find PFAS in the birds, as these toxins have accumulated in all kinds of wildlife and even the human body. However, they were shocked by the quantities. "The biggest increase is in the livers of wading birds. We found up to 180 times more PFAS than previously," said postdoctoral fellow and lead author Junjie Zhang, per Norwegian SciTech News. PFAS have been linked to numerous health effects, including multiple forms of cancer, liver damage, cholesterol disorders, fertility problems, hormone disorders, developmental disorders in children, and immune system problems. Unfortunately, because of the way they build up in the environment and food sources, higher levels of PFAS in wildlife are likely to translate to higher levels in humans, especially when found in water sources where people drink and fish. The study didn't just identify a higher concentration of PFAS; it also piloted a new testing method developed by study co-author Lara Cioni called the "Total Oxidizable Precursor assay." This test shows some of the subgroups of PFAS that have been a primary focus and identifies substances that break down into them. Looking at the whole chain — both the toxic products and their previously lesser-known origins — gave researchers a fuller picture of where the toxins were coming from, which is vital information for prevention. "We need to find out more about the sources, but also about the effects PFAS have on wading birds, other animals and humans," said professor Veerle Jaspers of the Department of Chemistry at NTNU, per Norwegian SciTech News.

‘Hidden risk' of widely-used prescription drugs — you're more likely to get the flu and Covid while on them
Since we take prescription drugs to feel better, it's alarming to think that some common ones can actually make you more sick. But that's precisely what a shocking new study out of Norway has revealed. 'We have found a surprising and potentially serious side effect of a class of anti-inflammatory drugs. They can help viruses spread more easily in the body,' Denis Kainov, a professor at the Norwegian University of Science and Technology (NTNU), said in a press release. Advertisement A new study has found some common drugs can actually make you more sick. Getty Images Janus kinase inhibitors — also known as JAKs — are commonly prescribed for autoimmune diseases like rheumatoid arthritis. You might know them by their brand names, such as Xeljanz, Olumiant and Rinvoq. But while they may ease inflammatory conditions, it seems they can also inflame your chances of catching a nasty bug. Advertisement 'Among the viruses that more easily affect the body with the help of these drugs are Rift Valley fever virus, influenza A, adenovirus and SARS-CoV-2, the virus that causes COVID-19,' Kainov said. Kainov and his team found that these drugs can suppress interferon-stimulated genes, which play a crucial role in the body's response to viral infections, thereby facilitating the spread of viruses. They therefore urge medical professionals to exercise caution when prescribing these drugs to patients who might be at risk. 'Among the viruses that more easily affect the body with the help of these drugs are Rift Valley fever virus, influenza A, adenovirus and SARS-CoV-2, the virus that causes COVID-19,' Kainov said. Getty Images Advertisement 'We recommend further studies to better understand how the drugs can be used optimally, especially during virus outbreaks or pandemics,' Aleksandr Ianevski, an NTNU researcher, said. JAKs aren't the only class of medication to make headlines recently for some unpleasant side effects. Other common drugs, such as statins — which are meant to lower cholesterol — and certain medications for high blood pressure have also been implicated in exposing patients to a higher risk of infection. Advertisement In a somewhat more bizarre twist, reports reviewed by the BBC suggest some common drugs that are meant to treat Parkinson's and other movement disorders have been pushing people into sexually deviant behavior. And the FDA recently issued a warning about generic versions of a widely-used hair loss drug — finasteride — that is frequently distributed by popular telehealth brands like Hims and Keeps, after dozens of users reported sexual dysfunction, brain fog and suicidal thoughts.

Scientists find common arthritis drugs could weaken immunity against Covid, flu
Drugs are meant to make us feel better, either by treating disease or easing symptoms. But sometimes, certain medicines could have unexpected side effects that could make things worse, especially during a virus outbreak.A team of scientists in Norway has now found that a commonly used group of anti-inflammatory drugs called Janus kinase inhibitors, or JAK inhibitors could actually make it easier for viruses like influenza and Covid-19 to spread inside the findings are published in NAR Molecular drugs are often used to treat chronic conditions such as rheumatoid arthritis and other autoimmune according to researchers at the Norwegian University of Science and Technology (NTNU), they may also reduce the body's natural defences against viruses."We have found a surprising and potentially serious side effect of these drugs. They can help viruses spread more easily in the body,' said Professor Denis Kainov from NTNU's Department of Clinical and Molecular simple terms, the drugs seem to weaken an important signalling process in the immune system, one that helps protect healthy cells from being this pathway is blocked, the body's ability to detect and fight viruses is research team tested the effects of JAK inhibitors on human cells taken from the lungs, eyes, and also studied mini-organs grown in the lab and used advanced gene analysis found that a drug like baricitinib, commonly used for arthritis, slows down the activity of certain genes that kick into action when a virus genes act like a security system in the body. When it's down, viruses like SARS-CoV-2 (which causes Covid) adenovirus, and influenza A can spread Ravlo, the study's lead author, said the findings show that while JAK inhibitors are useful in managing inflammation, they could carry hidden risks during viral infections, especially for people with a weak immune system.'Doctors should be careful when prescribing these drugs, particularly during times when viruses like Covid-19 or flu are circulating widely,' Ravlo the researchers also said that in controlled environments, such as during vaccine development or drug screening, this side effect might actually be instance, by making it easier to test how well a new antiviral treatment scientists are now calling for more research into how these drugs work in real-world conditions.

'Cheap' weekly activity 'slows down' brain ageing
Scientists at the Norweigan University of Science and Technology stressed an important message about preventing cognitive decline Researchers suggest that a simple weekly habit may be key to preventing cognitive decline and dementia. If you're not particularly fond of the gym, this might seem like bad news - the answer is regular exercise. A new study, led by the Norwegian University of Science and Technology, reviewed various animal and human studies to better understand the connection between fitness and ageing. The analysis focused on several factors, including brain plasticity, inflammation, and blood flow, all of which are linked to the development of neurodegenerative diseases. While current guidance recommends 150 minutes of moderate or 75 minutes of high-intensity exercise per week, the team suggests that even smaller amounts can benefit the brain. They emphasised the importance of this message, as it may encourage people to kick off their exercise journeys. Professor Ulrik Wisløff, who co-authored the research, explained: "We believe it's time for health authorities to provide clearer advice on how important exercise is for the brain. Our review shows that even small doses of high-intensity activity – equivalent to brisk walking where you can't sing – can reduce the risk of dementia by up to 40%." Postdoctoral researcher, Atefe Rafiee Tari, also told Norwegian Sci Tech News: "Today's recommendations emphasise total activity, but we show that even small amounts of high intensity exercise have an effect on the brain... Exercise is cheap, accessible and has no side effects. It should be considered a first-line measure to preserve brain health." Dementia is a term used to describe several conditions, including Alzheimer's disease, that involve a continuous decline in brain function. The NHS estimates that over 944,000 people in the UK are living with dementia, including one in every 11 individuals aged over 65. Unfortunately, there is no cure for dementia, but treatments are available to reduce its symptoms, which may include confusion, forgetfulness and speech problems, among others. Despite this, it's also worth noting that minor lifestyle adjustments may prevent up to 45% of cases. Get exercise advice straight to your WhatsApp!

Last year, Oxford University found that lacking physical activity, alcohol, and pollution exposure were among the factors that could worsen dementia risk after scrutinising some 40,000 brain scans. Meanwhile, Dr Valter Longo, who directs the Longevity Institute at the University of Southern California, has also stressed the significance of exercise and brisk walking for sustained health. In a previous blog, he said that even strolling for one hour per day could be enough to make a difference. "Walk fast for an hour every day," Dr Longo said. On the weekend, walk everywhere, even faraway places (avoid polluted areas as much as possible)." A brisk walk describes moving at a pace of around three mph. If you're unsure how fast you're walking, the NHS recommends downloading the free Active 10 app on your smartphone, which can suggest how to boost your speed. The health authority's advice adds: "If you're not very active but are able to walk, increase your walking distance gradually. If your joints are a problem, check whether your local swimming pool holds exercise classes. "The water helps to support your joints while you move and can help you strengthen your muscles."

Scientists raise alarm after analyzing samples from migratory birds: 'Not particularly good news'
Researchers are finding more "forever chemicals" than ever before in migratory birds' bodies and food sources. As the Norwegian University of Science and Technology reported, forever chemicals, or PFAS, are increasingly prominent inside the birds and in the food they eat. The team analyzed samples from 25 migratory birds and also from 30 shellfish in areas where the birds often eat. The test area was in China, along a migration route with rapidly declining bird populations. "The biggest increase is in the livers of wading birds," said postdoctoral fellow Junjie Zhang, who collaborated on the study, via "We found up to 180 times more PFAS than previously. … This suggests that previous methods have not been good enough at detecting certain types of PFAS." The researchers published their findings in the Journal of Hazardous Materials. Discovering more PFAS than previously expected is concerning because of how harmful these substances can be. Since these chemicals degrade extremely slowly and never break down, they accumulate in natural areas and inside the bodies of animals and people. Certain per- and polyfluoroalkyl substances have been linked to increased risks of cancer, kidney disease, developmental problems, and other conditions. Companies produce products for human consumption that contain PFAS, and they have been appearing in unexpected places that impact our daily lives. This study's findings are also significant because they highlight a new and promising method for analyzing samples and detecting PFAS, according to the university report. Accurate detection will allow us to understand the origin of PFAS better and take proactive measures to target them. Do you worry about having toxic forever chemicals in your home? Majorly Sometimes Not really I don't know enough about them Click your choice to see results and speak your mind. According to the writeup, the revelation that forever chemicals originate from unknown sources "is not particularly good news." The researchers' results indicate that the chemicals may be affecting our lives more significantly than we thought. They stressed the need for additional studies to learn more about the sources of PFAS and their effects on humans and animals. Though this news is unsettling, there are practical ways to eliminate forever chemicals from your life and household. For example, you can bring your own reusable to-go containers to restaurants. Upgrading your cookware and buying natural beauty products can also limit your exposure as more research continues to trickle in about PFAS sources and risks.
