Researchers think they now know why a particularly virulent form of E. coli that swept through northern Germany last May was so hard to trace: The germs responsible eluded detection by going into a self-induced deep sleep.
Two new studies show that when stressed, E. coli can turn off most signs of life. That’s a problem for food-safety officials because their germ-...
Sharks, billfish, cod, tuna and other fish-eating fish — the sea’s equivalents to lions on the Serengeti — dominated the marine world as recently as four decades ago. They culled sick, lame and old animals and kept populations of marine herbivores in check, preventing marine analogs of antelopes from overgrazing their environment.
But the reign of large...
When it comes to weight management, the timing of dining is pivotal, a new study indicates. At least in rodents, food proved especially fattening when consumed at the wrong time of day.
As nocturnal animals, mice normally play and forage at night, often in complete darkness. With even dim chronic illumination of their nighttime environment, however, the animals’ hormonal dinner bells...

Each of us is a metropolis. Bustling about in everyone's body are tens of trillions of microbes. Some are descended from starter populations provided by mom during birth. Additional bacteria, yeasts, and other life forms hitchhike in with foods. By age 3, everyone's gut hosts a fairly stable, yet diverse, ecosystem.
Most of the tiny stowaways hide out in the...
