Basic research generates jobs and competitiveness
Trained as a mechanical engineer in India, Subra Suresh researched the interfaces between engineering, biology and materials science before becoming dean of engineering at MIT and, as of October, director of the U.S. National Science Foundation. In February in Washington, D.C., at the annual meeting of the American Association for the Advancement of Science, Suresh […]

Warming is accelerating global water cycle
Fresh water evaporates from the oceans, rains out over land and then runs back into the seas. A new study finds evidence that global warming has been speeding up this hydrological cycle recently, a change that could lead to more violent storms. It could also alter where precipitation falls — drying temperate areas, those places where most people now live.

Alpine Antarctica, before the ice
A new survey may have unveiled the birthplace of the world’s largest ice sheet.
