The Microbiome Is Shaped By Genetic Differences In The Immune System

Differences in the genes of the immune system sculpt the assortment of bacteria that colonize the digestive system, new research[1] by scientists at the University of Chicago indicates. “When the input is standardized, you can compare mice of different genetic strains and see what these genetics do to the microbiome in recipient mice. This approach […]

Habitual Tea Drinking Contributes Positively To Brain Structure

A new study looks at the effects of tea drinking on the brain[1]. Researchers recruited healthy older participants to two groups according to their history of tea drinking frequency and investigated both functional and structural networks to reveal the role of tea drinking on brain organization. “Tea has been a popular beverage since antiquity, with […]

Our Brains Walk A Fine Line For Maximum Performance

To maximize information processing, the brain tunes itself to be as excitable as possible without tipping into disorder, new research[1] confirms. Researchers long wondered how the billions of independent neurons in the brain come together to reliably build a biological machine that easily beats the most advanced computers. All of those tiny interactions appear to […]

Gender-distinct Brain Circuit For Depression Identified

A single circuit in mice that activates during stress and is controlled by testosterone has been found by researchers at Michigan State University. The results[1], published in Biological Psychiatry, focus on the activity between neurons in the ventral hippocampus, which become active under stress and emotion, and their activation of nucleus accumbens neurons, critical players […]
