One of the pioneers in research on sleep:wake circadian genes, Amita Sehgal, PhD, has discovered that fruit flies' appetite and consumption are controlled by two rival sets of clocks, one in neurons and the other in the fly fat body, which is analogous to the liver.

Word of the Day
  • an ornament or knob in the shape of a flower
  • In architecture, a floral ornament; specifically, the large conventional flower usually placed in the center of the abacus of a Corinthian capital or classic ceiling-caisson; also, the floreated termination of a Gothic finial.
[ "The word 'fleuron' comes from French."]
