Excess weight, obesity more deadly than previously believed
Excess weight or obesity boosts risk of death by anywhere from 22% to 91%—significantly more than previously believed—while the mortality risk of being slightly underweight has likely been overestimated, according to new CU Boulder research. The findings, published Feb. 9 in the journal Population Studies, counter prevailing wisdom that excess weight boosts mortality risk only in extreme cases.

Child body weight has limited effects on mood and behavioural disorders, study suggests
The results suggest that some previous studies, which have shown a strong link between childhood obesity and mental health, may not have fully accounted for family genetics and environmental factors. Children with obesity are more likely to be diagnosed with depression, anxiety, or attention-deficit hyperactivity disorder (ADHD). But the nature of the relationship between obesity and these mental health conditions is not clear.

A surgeon looked at 7 clitorises under a microscope and found they're packed with 10,000 nerve fibers. It could be a game-changing discovery.
Gender-affirming surgeon and nerve researcher Blair Peters is the first person to quantify the number of nerve fibers in the human clitoris. Until now, sex researchers and educators have said the clitoris has an estimated 8,000 nerve fibers, but that well-cited number comes from a study on cows' genitals, which is mentioned in "The Clitoris," a book published in 1976.

PFAS left dangerous blood compounds in nearly all US study participants
Nearly all participants in a new study looking at exposure to PFAS “forever chemicals” in the US state of North Carolina have multiple dangerous compounds in their blood, and most at levels that researchers say requires medical screening. The North Carolina State University study, which is among the largest ever conducted, checked about 1,500 blood samples from people living in the Cape Fear River basin over several years. It’s the first study to recommend screening for cancers, kidney damage, heart disease and other health issues linked to the chemicals, using newly developed physicians’ guidelines for PFAS exposure.

Farts say more about your health than you think — now, scientists are listening
AS DAVID ANCALLE opened video after video of diarrhea this year, it struck him: This is not what he expected to be doing for his Ph.D. Ancalle, a mechanical engineering student at Georgia Tech who researches fluid dynamics, is currently working to demystify the acoustics of urination, flatulence, and diarrhea. His team is training AI to recognize and analyze the sound of each bathroom phenomenon; in fact, research suggests that tracking the flow of our excretions could benefit public health.

Nose Picking Could Put You At A Risk Of Alzheimer's And Dementia, Says Study
Digging your nose is a curious habit. Some people pick their nose out of boredom or nervousness. However, according to a new study, this habit could put you at a risk of developing Alzheimer's and dementia. According to a team of researchers at Griffith University, Australia, they demonstrated that a bacteria can travel through the olfactory nerve in the nose and into the brain in mice, where it creates markers that are a revealing sign of Alzheimer's disease.

Particles made from purified sand gain momentum as obesity treatment
Scientists are searching far and wide for new tools in the battle against rising obesity rates, and lately a promising candidate has emerged from piles of purified sand. A new study has bolstered the potential of silica particles made from this material by showing how they block enzyme activity to hamper the body’s uptake of fats and sugars, while also hinting at the ideal design for the optimal anti-obesity effects.

'Forever Chemicals’ Found in Every Umbilical Cord Blood Sample in Global Study
“Forever chemicals,” or perfluoroalkyl and polyfluoroalkyl substances (PFAS), have made quite a few appearances in the news cycle lately. These thousands of manufacturing chemicals leach into the food and water supply, making it nearly impossible to avoid absorption into the human body. Once in the body, they don’t go away—hence the name “forever chemicals”—and can cause a host of health concerns, from thyroid disease and cancer to liver damage and fertility issues.

A long-lasting male contraceptive jab could be available within a year
A male contraceptive jab that last 10 years and prevents men passing HIV and other sexually transmitted diseases could be available within a year. The injection will be less painful and also reversible making it more simpler than a vasectomy. Researchers at the Indian Institute of Technology have completed final trials of the jab and experts say the jab known as Risug- an acronym for reversible inhibition of sperm under guidance - could be available within 12 months.

With advances in medicine, could 80 become the new 40?
For all the advances in medical technology humans have developed, there is one thing it hasn't been able to do: stop us from getting old. We've managed to extend the human lifetime dramatically in the last couple of centuries, greatly diminishing infant and child mortality and pushing back on disease with antibiotics and vaccines.

Having ‘good’ posture doesn't prevent back pain, and 'bad' posture doesn't cause it
We’ve all been told our whole lives we need ‘good’ posture: sit up straight, stand straight with shoulders back, and lift by bending the knees. It turns out there’s really no evidence for that advice.

A plant-based diet is good for your wallet, not just your health
At a time when every dollar counts, many of us are changing the way we eat to save money. Take mother of three and Hong Kong resident Asher Chan, for instance. A lifelong vegetarian, she transitioned to veganism in the past year for a couple of reasons – one of which was the rising cost of milk and eggs. Now her family uses plant-based alternatives to these foods, which she says are more affordable.
