Age is a key risk factor associated with the severity of symptoms caused by SARS-CoV-2, and there is an urgent need to reduce COVID-19 morbidity and mortality in elderly individuals. We discuss evidence suggesting that trained immunity elicited by BCG vaccination may improve immune responses and can serve as a strategy to combat COVID-19 in...
Psychedelic experience may not be required for psilocybin’s antidepressant-like benefits
UNIVERSITY OF MARYLAND SCHOOL OF MEDICINE University of Maryland School of Medicine (UMSOM) researchers have shown that psilocybin–the active chemical in “magic mushrooms”– still works its antidepressant-like actions, at least in mice, even when the psychedelic experience is blocked.

GUT IMMUNE SYSTEM MAY PLAY A ROLE IN NUTRITION
The small intestine is ground zero for survival of animals. It is responsible for absorbing the nutrients crucial to life, and it wards off toxic chemicals and life-threatening bacteria. In a new study in the journal Science, researchers report the critical role that the gut’s immune system plays in these key processes. The findings may...
