Regularly taking breaks from eating—for hours or days—can trigger changes both expected, such as in metabolic dynamics and inflammation, and surprising, as in immune system function and cancer progression.

Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

Stopping Ebola in Its Tracks Richard Preston brought the threat of emerging infectious diseases to the consciousness of his readers in The Hot Zone. The book graphically describes how the Ebola virus causes massive internal bleeding, which kills up to 90 percent of the people it infects. Now National Institutes of Health scientists are making promising advances to stop disease spread. Researchers have identified a viral protein that destroys endothelial cells, the cells that line the blood vess

FEATUREBattling Bad Behavior COURTESY YURI MATROSOVICHAnti-alcohol propaganda such as this poster titled "Bartered" was distributed in the Soviet Union during the 1980s Many of society's most vexing problems - the rise of antibiotic resistance, the current epidemic of obesity, armed conflicts that leave both sides worse off - have their roots in the suboptimal and often puzzling actions of individuals.

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
