A gene's first 'kiss' sets off that affair known as puberty

...searchers that a gene called GPR54 is defective in children with a rare disorder that inhibits puberty's onset. To better understand what role GPR54 plays in the initiation of puberty, as well as learn about KiSS-1, which in earlier rodent studies had been identified as a molecule that activates a signal rece...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

... Over a period of four years, about a third of the children suffered from amebic colitis, an ulceration of the stomach lining.

Bird Brains Show How Trial and Error May Contribute to Learning

... A similar brain pathway in humans may explain how children learn to talk by listening to themselves and others, and how adults learn and hone new motor skills, such as tennis. The process relies on feedback about what works and what doesn't, also called experience-dependent or performance-based learning. "T...
