Trading energy for safety, bees extend legs to stay stable in wind

CAMBRIDGE, Mass., June 2, 2009 -- New research shows some bees brace themselves against wind and turbulence by extending their sturdy hind legs while flying. But this approach comes at a steep cost, increasing aerodynamic drag and the power required for flight by roughly 30 percent, and cutting in...

Synthetic biology can help extend anti-malaria drug effectiveness

In addition to providing a simple and much less expensive means of making artemisinin, the most powerful anti-malaria drug in use today, synthetic biology can also help to extend the effectiveness of this drug. Fermenting artemisinin via engineered microbes, such as yeast, can be done at far lower...

Eating less may not extend life

Genes that both extend life and protect against cancer identified

A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported today in the journal Nature Genetics identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm. Many o...

'Empty nester' parent birds use recruitment calls to extend offspring care

Caloric restriction won't dramatically extend life span in humans: UCLA research

Severely restricting calories over decades may add a few years to a human life span, but will not enable humans to live to 125 and beyond, as many have speculated, evolutionary biologists report. "Our message is that suffering years of misery to remain super-skinny is not going to have a big payo...

Researchers extend mouse lifespan by protecting against free radicals

Scientists at the University of Washington and their colleagues at other research centers have found a way to significantly extend the lifespan of mice while reducing the impact of the aging process.
