A new study in ants identifies a peptide that plays an important role in regulating reproduction. This research illuminates a potential trajectory for the evolution of distinct social castes—workers and queens.
Scientists find that certain neurons release nitric oxide onto nearby blood vessels, and potentially use this mechanism to control awareness in the brain.
Scientists have long debated the evolutionary origins of human speech. New research reveals neural circuits in the brains of monkeys that may represent the source of our unique speech capabilities.
A new study sheds light on the mysterious ways in which evolution may tweak the brain to shape behavior. It started with a close look at two Drosophila species and their mating maneuvers.
Scientists have found a metabolic particularity in tumor cells lacking oxygen. The discovery might point to new drugs to target the most difficult-to-treat spots within a tumor.
A new study shows that a group of neurons, previously thought to die in the course of development, in fact become incorporated into the brain’s cortex. This research has implications for understanding—and possibly treating—several brain disorders.
Scientists have found a new way to trawl blood samples for snippets of RNA released by tumors or diseased organs. The method might eventually help doctors diagnose and track a wide range of medical conditions.
Researchers have uncovered the genetic factors that make some people susceptible to Whipple's disease, an intestinal inflammatory disorder that causes diarrhea, pain, and weight loss.
