For the first time, scientists have detected microscopic microplastics lodged in the human brain. Researchers in Germany and Brazil say that 8 out of 15 autopsied adults had microplastics detected within their brain’s smell centers, the olfactory bulb. The particles were likely breathed in over a lifetime, since tiny floating microplastics are ubiquitous in the… read on > read on >
People with rare genetic variants linked to degenerative brain disorders like Parkinson’s disease are at increased risk of developing ALS, a new study finds. Further, having these genetic variants increases the risk of a person having faster-progressing ALS (amyotrophic lateral sclerosis) and dying earlier, researchers found. The strongest link was with Parkinson’s disease, results show.… read on > read on >

Each inhaler dose contains some of the most potent greenhouse gases known, and they are adding up, researchers reported recently in the Journal of the American Medical Association. By the time some inhalers are empty, they have… read on > read on >
Newfangled designs intended to make football helmets more protective have overlooked one key component, a new study suggests. Nearly a third of concussions in pro football involve impacts to the facemask, a part of the helmet that has remained mostly unchanged during the past decade, researchers say. Facemask enhancements could help protect players and minimize… read on > read on >
People should prepare for the fall cold and flu season by getting the updated influenza and COVID-19 vaccinations, an infectious diseases expert says. “When my patients ask me if they should be getting a COVID vaccine this year, yes, essentially anybody over the ages of 6 months, I’m recommending it,” Dr. Nicholas Turner, an assistant… read on > read on >
One third of cinnamon products tested by Consumer Reports contained elevated levels of lead, the watchdog agency warned Thursday. The finding follows concerns about metals in foods after tainted cinnamon applesauce poisoned hundreds in 44 states last year, most of them children. In the new study, Consumer Reports tested 36 cinnamon products and discovered high levels of… read on > read on >
Over 5 million Americans could benefit if the U.S. Food and Drug Administration approves the “magic mushroom” psychedelic psilocybin as a treatment for depression, researchers estimate. “While our analysis is a crucial first step, we’ve only scratched the surface in understanding the true public health impact psilocybin therapy may have,” said study co-author Dr. Charles Raison.… read on > read on >
Smokers who make the decision to quit will see almost immediate health benefits, including a quick drop in their risk for atrial fibrillation, new research shows. “The findings provide a compelling new reason to show current smokers that it’s not too late to quit and that having smoked in the past doesn’t mean you’re ‘destined’… read on > read on >
Initially approved to treat type 2 diabetes, Ozempic and Mounjaro also can help people with type 1 diabetes lose weight and control their blood sugar levels, a new study finds.
