Exposure To Cold Air May Promote Longevity In Mammals
Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why. Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments - and this genetic program also exists in warm-blooded animals, including humans...

Bacteria Producing Nitric Oxide Extend Life In Roundworms
Nitric oxide, the versatile gas that helps increase blood flow, transmit nerve signals, and regulate immune function, appears to perform one more biological feat - prolonging the life of an organism and fortifying it against environmental stress, according to a new study. The study reveals that a roundworm called Caenorhabditis elegans, an animal widely used in laboratory studies of aging, lives significantly longer when fed bacteria capable of manufacturing nitric oxide...

Study Of Tiny Roundworms Provides Clue To Observed Human Health Benefits From Omega Fatty Acids
A search for genes that change their levels of expression in response to nutrient deprivation has uncovered potential clues to the mechanism underlying the health benefits of omega fatty acids. In the journal Genes & Development, Massachusetts General Hospital (MGH) researchers describe finding that feeding omega-6 fatty acids to C. elegans roundworms or adding them to cultured human cells activates a cellular renewal process called autophagy, which may be deficient in several important diseases of aging...

Sloths simply can't get away from scientists
They have studied their locomotion, snoozing patterns, social lives, appetite and hair. Yes, scientists are fascinated by slothsThe name of the sloth is synonymous with a certain style of sin. But scientists pursue them for other reasons, too. The animals move – something they do on occasion – in what can seem mysterious ways. They hang upside down from tree limbs, and sometimes amble that way there. On the ground, ambling right-side-up is their preferred way to get from here to slightly over there. They often snooze.A study called Three-Dimensional Kinematic Analysis of the Pectoral Girdle During Upside-Down Locomotio...
