The neuropeptides, or ligands, which are calledorexin-A and orexin-B, and the receptors, OX1R and OX2R, allude to theGreek word orexis, for appetite.

...thology, like that in teen-age anorexia or loss of appetite in the elderly," said Shay, a professor of nutritional biochemistry. "We are certainly not saying that this is a cause of anorexia, but these findings hint at exacerbating or accelerating factors.

A VORACIOUS appetite for pests makes ladybirds, or ladybugs, a gardener's bestfriend. But there is a problem with these biological pest-killers-they tend tofly off before they've finished the job.
