With implications for research around postpartum depression and other health issues, scientists have tracked the changes pregnancy brings to the female brain. These changes weren’t subtle: Big shifts in what’s known as the brain’s “white matter” versus “gray matter” were observed, according to a team from the University of California, Santa Barbara (UCSB). “The maternal…  read on >  read on >

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 >

Fatty liver disease linked to diabetes and obesity can easily progress to liver cirrhosis, but new research suggests that GLP-1 medicines like Ozempic can help stop that. In a new decades-long study, veterans with diabetes and what’s known as metabolic dysfunction-associated steatotic liver disease (MASLD) were 14% less likely to progress to cirrhosis if they’d…  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 >

Vaping may look cool when you’re young, but it appears to be dulling the brains of college students, a new study warns.

Mott Children’s Hospital National…  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 >
