Population of rare gorillas may be increasing in war-torn Congo
...e Conservation Society (WCS). WCS conservationists say
that a band of park guards who have heroically defended the gorillas and their rainforest home in eastern Democratic Republic of Congo, have played a key role in safeguarding these endangered primates. The census, led by WCS project director Innocent...

Mahadevan and former students and postdocs Yol Forterre, Jan M. Skotheim, and Jacques Dumais. When an insect brushes up against a hair trigger, the plant responds by moving water to actively change the curvature of its leaves. While exactly how the w...
Green tea extract boosts exercise endurance 8-24%, utilizing fat as energy source
...level on endurance capacity is controversial, they say
that increased supply of circulating fatty acids would "induce the uptake of fatty acids, and thereby stimulate lipid metabolism in muscle." Indeed, lab results showed that muscular beta-oxidation was higher in GTE-fed mice (compared with non-exerci...
Reviewing scientists say proposed conservation measures unlikely to help whales

that ring formation is a complicated way to construct a microtubule binding structure, a microtubule binding ring might be uniquely suited to fulfill the functions of the Dam1 complex. In comparison with the purified Dam1, the Dam1 mutants produced ...

Japanese and University of California, Berkeley, researchers. A new study shows that melatonin, a hormone available without prescription, has broader effects in the brain than once thought. In experiments on the Japanese quail, the researchers found ...
Physics team puts new twist on spin hall effect
... in conventional bulk semiconductors. Team members say
the more than 10 times larger signal detected in the Hitachi device can be attributed to the special layered design of the semiconductor chip that yielded operation in a regime close to the intrinsic spin Hall effect. "They are both beautiful experi...
Study finds direct association between cardiovascular disease and periodontal bacteria

the findings are not proof that the bacteria cause cardiovascular disease, directly or indirectly. "What was interesting to us was the specificity of the association," said Mose Desvarieux, M. D., Ph. D., the study's lead author and an infectious dis...

their ultimate goal is a comprehensive computer model of how cells work. A description of all protein-interaction circuits would make such a model possible. "We'd like to simulate diseased cell types, such as cancer cells, and then simulate the effec...
