Relativistic electrons uncovered with NASA's Van Allen Probes

Earth's radiation belts, two doughnut-shaped regions of charged particles encircling our planet, were discovered more than 50 years ago, but their behavior is still not completely understood. Now, new observations from NASA's ...

How drug-resistant bacteria build defences

Improved understanding of the way hundreds of different types of disease-causing bacteria operate could help pave the way to tackling their effects, according to leading scientists.

Study finds surprising variability in shape of Van Allen Belts

The shape of the two electron swarms 600 miles to more than 25,000 miles from the Earth's surface, known as the Van Allen Belts, could be quite different than has been believed for decades, according to a new study of data ...

Study of electrons in space could help weather forecasting

Researchers have discovered a formerly undetected impact of space weather on the polar atmosphere, which may explain some previously unexplained variations in winter weather patterns. Their results, published today (Tuesday ...

New technique traces ejected electrons back to atomic shells

(Phys.org) —In a detailed study of how intense light strips electrons from atoms, researchers used an X-ray laser, SLAC's Linac Coherent Light Source (LCLS), to measure and sort the ejected electrons and discover how this ...

NASA spacecraft records 'Earthsong'

Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.
