Keeping Time with Drosophila
Laura Bonetta | Feb 3, 2002 | 10 min read
Circadian clocks—the biological timekeepers that operate on a daily cycle—keep virtually every living creature in tune with its environment. These internal clocks regulate a wide range of fundamental biological processes, including movement, smell, sleep, mating, and feeding. A true circadian clock is endogenous; that is, it keeps time even in the absence of external cues. The clock can, however, be reset, or entrained, by daylight, allowing the synchronization of circadian rhythms t

Short Shrift to Evolution?
Barry Palevitz and Ricki Lewis | Feb 1, 1999 | 7 min read
Editor's Note: In this essay, the authors--both scientists and writers--discuss recent news stories on evolution and express their opinions on how the stories were handled by the mainstream press. Evolution took center stage at the National Association of Biology Teachers (NABT) annual meeting in Reno, Nev., Nov. 3-8, 1998. If the teachers needed a theme, evolution was a logical choice--after all, it underlies and unifies contemporary biology. But NABT had other fish to fry. Despite a spate of c
Who Sleeps?
The Scientist and Jerome Siegel | Mar 1, 2016 | 10+ min read
Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.
