Competing to create a more energy-efficient air conditioner
A University of California, Davis, challenge to build more energy efficient air conditioning has spurred a major global manufacturer to build a rooftop air conditioner that is 40 percent more energy-efficient ...
Squid skin protein could improve biomedical technologies, study shows
The common pencil squid (Loliginidae) may hold the key to a new generation of medical technologies that could communicate more directly with the human body. UC Irvine materials science researchers have d ...
Humans have a nose for gender

New study finds evolution mostly driven by brawn, not brains
The most common measure of intelligence in animals, brain size relative to body size, may not be as dependent on evolutionary selection on the brain as previously thought, according to a new analysis by scientists.
Asteroid fragments collected by Hayabusa could hint at solar system origin
University of Manchester scientists are among the few in the world selected to analyze minute asteroid fragments which could shed light on the origin and evolution of the solar system.
First human tests of new biosensor that warns when athletes are about to 'hit the wall'
A new biosensor, applied to the human skin like a temporary tattoo, can alert marathoners, competitive bikers and other "extreme" athletes that they're about to "bonk," or "hit the wall," scientists are reporting. The study, ...
Nature journal retracts 'game-changer' stem-cell study (Update)
Leading science journal Nature said on Wednesday it had withdrawn a flawed stem-cell study hailed when it was published in January as a "game-changer" in the quest to grow transplant tissue.
Bacterium uses natural 'thermometer' to trigger diarrheal disease, scientists find
How does the bacterium Shigella—the cause of a deadly diarrheal disease—detect that it's in a human host? Ohio University scientists have found that a biological "RNA thermometer" monitors whether the environment is rig ...

Naked mole rat may hold the secret to long life
Compared to the average three year life span of a common rat, the 10 to 30 year life of the naked mole rat, a subterranean rodent native to East Africa, is impressive. And compared to the human body, the body of this rodent ...
Big brains are pricey, guppy study shows
Bigger brains can make animals, well, brainier, but that boost in brain size and ability comes at a price. That's according to new evidence reported on January 3rd in Current Biology, in which researchers artifi ...
