A new study casts doubt on the theory that oxidative stress shortens lifespan. Researchers have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer. The results contradict the popular theory that production of toxic reactive [...]

The deaths of nearby relatives has a curious effect on the bacterium Caulobacter crescentus — surviving cells lose their stickiness. Biologists report that exposure to the extracellular DNA released by dying neighbors stops the sticky holdfasts of living Caulobacter from adhering to surfaces, preventing cells from joining bacterial biofilms. Less sticky cells are more likely [...]

New findings suggest that an enzyme in the brain known as PI3 kinase might control the increased generation of body heat that helps burn off excess calories after eating a high-fat meal.

An incidental discovery in a wood products lab has produced a new pressure-sensitive adhesive that may revolutionize the tape industry — an environmentally benign product that works very well and costs much less than existing adhesives based on petrochemicals.
