Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.

Study highlights gaps in preeclampsia risk assessment and aspirin use

A new study sponsored by Mirvie, which is the first to evaluate U.S. Preventive Services Task Force (USPSTF) guidelines for preeclampsia risk and aspirin prescription in a single, nationally representative, prospective population, found while high-risk factors had sufficient value in estimating risk, there's limited value for the moderate risk category - leading to nonspecific recommendations for aspirin use, a recognized prevention tool.

Brain's tiny region dictates how memories are formed and separated

Life may unfold as a continuous stream, but our memories tell a different story. We do not recall the past as one long, unbroken text. Instead, we remember it as a series of meaningful events, like how sentences are structured with grammar and punctuation.
