Scientists solve 30-year-old aurora borealis mystery

UCLA space scientists and colleagues have identified the mechanism that triggers substorms in space; wreaks havoc on satellites, power grids and communications systems; and leads to the explosive release of energy that causes ...

Material may help autos turn heat into electricity

Researchers have invented a new material that will make cars even more efficient, by converting heat wasted through engine exhaust into electricity. In the current issue of the journal Science, they describe a material with ...

Electron microscopy enters the picometer scale

J├╝lich scientists have succeeded in precisely measuring atomic spacings down to a few picometres using new methods in ultrahigh-resolution electron microscopy. This makes it possible to find out decisive parameters determining ...

Study: No gender differences in math performance

We've all heard it. Many of us in fact believe it. Girls just aren't as good at math as boys. But is it true? After sifting through mountains of data - including SAT results and math scores from 7 million students who were ...
