On November 11, 1954, Syuiti Mori turned out the lights on a small group of fruit flies. More than sixty years later, the descendents of those flies have adapted to life without light. These flies—a variety now known as ...

(Phys.org)—Many animals including birds and insects have been observed to perceive geomagnetic fields. Past studies have demonstrated that cryptochrome/photolyase family (CPF) light receptor proteins are involved in animal ...
Dmitri A. Nusinow, Ph.D., assistant member at the Danforth Plant Science Center and researchers in his lab studying plants' circadian clock have discovered a gene that allows plants to remember daylight during the long nights ...

(Phys.org)—A team of researchers from institutions in the U.K. and Switzerland has identified a protein that is heavily involved in entrainment in fruit fly brains as part of coordinating the circadian clock. In their paper ...
Lack of adequate sleep can do more than just make you tired. It can short-circuit your system and interfere with a fundamental cellular process that drives physical growth, physiological adaptation and even brain activity, ...
