Older people who follow a Mediterranean diet are at a lower risk of cognitive decline, reports a new study that highlights the biological mechanisms related to the impact of diet on cognitive health.

Researchers have identified a suite of genes that influence head shape in humans, helping to explain head shape diversity and potentially conditions affecting the skull.

The way in which nanoplastics and a specific brain protein, α-synuclein, interact could create changes in the body that give rise to Parkinson’s disease (PD) and other related dementias, a new study suggests.

In a behavioral experiment, bees consumed the same amount of food, regardless of whether the solution contained pesticides or not, even when the pesticides were at concentrations high enough to “make the bees very ill.”

A new MIT study finds that microglia with mutant TREM2 protein reduce brain circuit connections, promote inflammation and contribute to Alzheimer’s pathology in other ways.

Children whose mothers are highly stressed, anxious or depressed during pregnancy may be at higher risk for mental health and behavior issues during their childhood and teen years.

Suicidal behavior is driven by a mix of psychological, social and biological factors. New research has identified overactive inflammation and loss of critical protection mechanisms in the brain as potential contributors to suicide risk.

New research finds the same genetic mechanisms at work during neural development in both humans and Nematostella vectensis.

The internal clocks of grizzly bears appear to keep ticking through hibernation, according to a genetic study. This persistence highlights the strong role of circadian rhythms in the metabolism of many organisms including humans.

Researchers have shed new light on the cellular processes behind Parkinson's and illustrated how disease progression can be halted in a mouse model.
