Health data from 5,744 adults over the age of 50 reveals an association between stressors such as discrimination and a relatively small proportion of younger infection-fighting immune cells.

An odorant found in the pee of pregnant mice—and in bananas—induces stress but also relieves pain in male mice, a study shows.

Researchers find that evolution can operate on extraordinarily fast timescales.

Rechtschaffen sought to understand the evolutionary purpose of shut-eye.

A large, long-term study across the US and Sweden finds potential correlations between specific pollutants and the proportions of male and female babies born.

Researchers identified a novel mechanism by which chemically induced stress is “remembered” by the mitochondria of worms more than 50 generations after the original trigger.

Neurons stressed with chemicals produce Wnt, which in turn triggers changes in the germline.

Abnormal sympathetic neuron growth leads to simultaneous activation of clusters of sensory neurons, causing the difficult-to-treat sensation.

Scientists show that an influx of noradrenaline can halt immune cells in mice.

Research in mice and humans points to oxidative stress and inflammation as likely drivers of noise-induced health effects such as hypertension and heart disease.

A chronically stressed amygdala can prime the heart to overreact to acute stress events, a new study shows.

Sound from cars, aircraft, trains, and other man-made machines is more than just annoying. It increases the risk of cardiovascular disease.

TMAO appears to both stabilize other plant proteins and influence the expression of stress-response genes, researchers report.

Corticosterone interferes with signaling in the skin that normally activates hair follicle stem cells, possibly explaining the link between stress and hair loss.

Take a break from the bench to puzzle and peruse.

In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.

Meet some of the people featured in the July/August 2020 issue of The Scientist.

Affectionate touches tap into the nervous system’s rest and digest mode, reducing the release of stress hormones, bolstering the immune system, and stimulating brainwaves linked with relaxation.
