Nanomagnets offer clues to how avalanches work

The behavior of avalanches has generated interest among physicists for the insights that they can provide about many other systems, not least of which is how snow falls down a mountainside. To that end, a team of researchers ...

Energy from solar wind favors the north

Using information from ESA's Swarm satellite constellation, scientists have made a discovery about how energy generated by electrically-charged particles in the solar wind flows into Earth's atmosphere—surprisingly, more ...

New analysis method predicts disruptive solar flares

Solar flares—violent explosions on the surface of the sun—can send blasts of radiation hurtling toward Earth. While the planet's magnetic field protects humans on the surface, powerful solar flares can disable satellites, ...

Study reveals strange magnetic behaviour 8-11 million years ago

Research by the University of Liverpool has revealed that strange behaviour of the magnetic field in the South Atlantic region existed as far back as eight to 11 million years ago, suggesting that today's South Atlantic Anomaly ...
