Good news has turned out to be bad. The ocean has helped slow global warming by absorbing much of the excess heat and heat-trapping carbon dioxide that has been going into the atmosphere since the start of the Industrial Revolution. All that extra carbon dioxide, however, has been a bitter pill for the ocean to [...]
Frogs and salamanders, those amphibious bellwethers of environmental danger, are being killed in Yellowstone National Park. The predator, Stanford researchers say, is global warming. One biology graduate student spent three summers in a remote area of the park searching for frogs and salamanders in ponds that had been surveyed 15 years ago. Almost everywhere she [...]
Individuals who take cholesterol-lowering statins before being hospitalized with pneumonia appear less likely to die within 90 days afterward, according to a new report.

A new study suggests that the prolonged fatigue after mild exercise that occurs in people with many forms of muscular dystrophy is distinct from the inherent muscle weakness caused by the disease. The research identifies a faulty signaling pathway that appears to cause exercise-induced fatigue in mouse models of muscular dystrophy and shows that Viagra [...]

A novel defense strategy displayed in response to marine viruses by some of the most abundant unicellular organisms found in our oceans has recently been demonstrated. The results enable a clearer understanding of the origin of, and reasons for, sexual reproduction in eukaryotes.
