Endangered frogs coexist with fungus once thought fatal
...lent strains of the fungus may have evolved. If it turns out that frog populations can develop resistance to the chytrid fungus, the researchers point out, then a conservation program of captive breeding and selecting for resistance could potentially thwart the extinction of these, and other, critically en...How roots control plant shoots
...constantly producing the carotenoid byproduct that turns off leaf growth. First, they grew thale cress plants with the mutant form of BPS1 known as bps1. Normal seedlings produce an increasing number of flat, broad, round leaves as they grow. Mutants grew only two smaller leaves shaped like triangles or...Stanford cooling tool may improve performance of athletes, soldiers

"We used a pressure differential to draw blood to the skin surface, then we applied heat to the skin to increase heat flow back to the core," Grahn says.

It turns out the same is true inside our bodies, where just the right touch among blood cells can mean the difference between good health and chronic conditions like heart disease and diabetes. The power of touch among blood cells is the focus of a team of b...INEEL uses extremophile bacteria to ease bleaching's environmental cost
...to T. brockianus' fondness for hot springs. But it turns out the bacterium doesn't fare as well as its enzyme in high pH conditions. "Along the way, we may figure out why the enzyme is stable in alkaline environments," Thompson says. "But if it works in industry, that's the most important thing right now."...Muscling in on a deadly cancer

The removal of the protein then induces alterations in the plant during its development, and from these alterations researchers can deduce the function of the protein in question.

To uncover LRP6's role in cancer, Bu's team took slow-growing cancer cells and altered the LRP6 gene so that it made more of the protein.
