Neural pathway key to sensation of pleasant touch identified

Studying mice, scientists at Washington University School of Medicine in St. Louis have identified a neural circuit and a neuropeptide—a chemical messenger that carries signals between nerve cells—that transmit the sensation ...

Treatment keeps alcoholic monkeys from drinking as much

A hormone produced by the liver called fibroblast growth factor 21 (FGF21) suppresses alcohol consumption in primates, finds a study published February 1 in the journal Cell Metabolism. Vervet monkeys with a strong preference ...

Biologists identify neural circuits associated with aging

Biologists at the University of Iowa have pinpointed how fruit flies—no matter their age—maintained neural circuits for certain motor functions, while losing their edge in other performance measures.
