Magnetic pumping pushes plasma particles to high energies

The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping. … read more

Monitoring air pollution after Hurricane Maria

When Hurricane Maria struck Puerto Rico on Sept. 20, 2017, the storm devastated the island's electrical grid, leaving many people without power for months. This lack of electricity, as well as other storm-related damage, prevented air-quality monitoring in many areas. Now researchers have shown that low-cost sensors that run on solar energy can be used to monitor air pollution after a disaster. … read more
