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 [...]

NASA’s Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars. This discovery suggests that liquid water remained on the planet’s surface a billion years later than scientists believed, and it played an important role in shaping the planet’s surface and possibly hosting life.

That stress during a mother’s pregnancy can cause developmental and emotional problems for offspring has long been observed by behavioral and biological researchers, but the objective measuring and timing of that stress and its results are difficult to prove objectively in humans. New experimental work has demonstrated the relationship between maternal stress and impairment of [...]
