Not all ions in tokamaks go with the flow

For the first time, scientists are measuring the rotation of the main (deuterium) plasma in the edge region of a fusion device. New spectroscopic measurements combined with state-of-the-art spectroscopic simulation made this ...

High-energy X-ray bursts from low-energy plasma

Solar flares shouldn't produce X-rays, but they do. Why? The one-size-fits-all approach to electron collisions misses a lucky few that lead to an intense X-ray burst. Scientists thought there were too many electron-scattering ...

Spacecraft measurements reveal mechanism of solar wind heating

Queen Mary University of London has led a study which describes the first direct measurement of how energy is transferred from the chaotic electromagnetic fields in space to the particles that make up the solar wind, leading ...

Team puts forth ideas on the nature of dark matter

Dark energy and dark matter comprise 96 percent of the total mass of the universe. Two main hypotheses about the nature of dark matter are presently debated. One posits that dark matter consists of massive compact halo objects; ...

Fidget spinner as centrifuge separates blood plasma

Some people use fidget spinners—flat, multi-lobed toys with a ball bearing at the center—to diffuse nervous energy or whirl away stress. Now, researchers have found a surprising use for the toys: separating blood plasma ...
