Chasing particles with tiny electric charges

All known elementary particles have electric charges that are integer multiples of a third of the electron charge. But some theories predict the existence of "millicharged" elementary particles that would have a charge much ...

Study finds electrical fields can throw a curveball

MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately ...

Cold War nuclear tests changed rainfall thousands of miles away

It's difficult to imagine quite how alarming it would have been for the world's meteorologists monitoring the atmosphere during the nuclear tests in the 1950s and early 60s. The radioactivity released in the Arctic and South ...
