In a new paper published this week in the Proceedings of the National Academy of Sciences, Aziz Sancar, MD, PhD, the Sarah Graham Kenan Professor of Biochemistry and Biophysics in the UNC School of Medicine, and his colleagues have taken an important step in understanding the underlying molecular signals that influence a broad array of biological processes ranging from the sleep-wake cycle to cancer growth and development.

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."]
