...esent only at very low levels, Sisodia notes, it's unlikely to be directly causing the widespread damage to nerve cells seen in FAD, but it may interfere with other proteins that could. Like dominoes falling, a change in presenilin sets off a chain reaction. "Think of it as a cascade," says Sisodia. "We don'...Two Long-sought Diabetes Gene Found

... area. This considerable reservoir of methane is unlikely to be exploited by humans. Most of the methane below the seafloor is trapped in rock as bubbles so tiny that they can be seen clearly only with a microscope. It is more likely that the methane may be used by deep-sea microorganisms. As the rock a...New Evidence For Corn's Ancestry Could Lead To Insect And Drought Resistant Crops
...ith a Ph.D. in anthropology, Eubanks would seem an unlikely person topursue research into the molecular biology of corn genes.
