In a discovery that challenges long-standing assumptions about necrotizing enterocolitis, a sudden and often fatal intestinal illness that affects premature infants, researchers at Washington University School of Medicine in St. Louis have identified previously unknown predictors for the disease

Sleeping in dark conditions may be important not only for quality sleep but also for heart health

The trillions of microorganisms living in our intestine influence our health, from digestion and metabolism to immunity. Yet scientists still struggle to understand how these microbes shape these important physiological functions because gut microbiomes are extraordinarily complex, redundant, and dynamic. New technologies are therefore essential for advancing microbiome research. Researchers at the University of Vienna…

A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson’s disease. The findings add to growing evidence that changes in the gut could be linked to Parkinson’s disease and may eventually help researchers identify new underlying mechanisms for the condition. 

A poor night’s sleep portends a bleary-eyed next day, but it could also hint at diseases that will strike years down the road. A new artificial intelligence model developed by Stanford Medicine researchers and their colleagues can use physiological recordings from one night’s sleep to predict a person’s risk of developing more than 100 health…

The gut microbiome in oral health and disease: evidence toward bidirectional oral-gut axis communication

The earlier dementia — of which Alzheimer’s disease is the most common — is detected, the better the prognosis for the person diagnosed

He claims to have spent millions of dollars tracking and streamlining nearly every aspect of his biology so as to radically slow — and even reverse, he claims — aging. He’s undeniably fit, purports to get more than eight hours of sleep each night and boasts a “fertility age” in his early twenties. Johnson is…

MASLD affects one in six people now and is projected to rise because of population growth, obesity and high blood sugar
