animals from chemical exposure, and the investigators found that the protection afforded by calorie restriction in normal mice was lost in PPARalpha-mutant mice. "PPARalpha may be one of a handful of receptors that play important roles in mediating t...
Viral proteins may prevent bacterial infections

...exists down there," he says. Besides, microbes can protect
themselves against the hyper-oxygenation by producing antioxidants. "We should look for bio-signatures of microbes that can produce these," says Priscu. He believes the bottom of Lake Vostok, like that of many lakes, could be anaerobic and so provide...
