Migration: Micro and Macro
Ruth Padel | Jun 1, 2012 | 3 min read
Biology and history both tell us that life began with migration: from cells to sharks, hummingbirds to human beings, life migrates for three reasons—survival, protection, and reproduction. 
Drosophila and E. coli Share a Strategy for Signal Release
Ricki Lewis | Nov 10, 2002 | 4 min read
The Faculty of 1000 is aWeb-based literature awareness tool published by BioMed Central. For more information visit www.facultyof1000.com. Science sometimes progresses by persistence and attention to detail. This was the case for the recent discovery that a bacterium and the fruit fly apparently share a strategy for signal release, despite one being a prokaryote and the other a eukaryote.1 The new view suggests that quorum sensing in bacteria and signal transduction in multicellular organisms
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

Eye of Science / Photo Researchers, Inc. "The general character and structure of the rod-like individuals, together with their vegetative multiplication by fission, renders their schizomycetous nature as individuals a matter hardly to be doubted: but, on the other hand, the question may fairly be asked whether the remarkable phenomena may not indicate a possible relationship in other directions." --Roland Thaxter, 1892 While walking through the New England woods one day in the late 19th c

©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat
