Meteorites show transport of material in early solar system

New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the planets formed. The results, ...

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 ...

Tiny particles can switch back and forth between phases

Three years ago, when Richard Robinson, associate professor of materials science and engineering, was on sabbatical at Hebrew University in Israel, he asked a graduate student to send him some nanoparticles of a specific ...

Tiny plastic particles in the environment

Wherever scientists look, they can spot them: whether in remote mountain lakes, in Arctic sea ice, in the deep-ocean floor or in air samples, even in edible fish—thousands upon thousands of microscopic plastic particles ...

Fresh sea spray turns 'sour' after being airborne

Aerosols are everywhere. These tiny liquid or solid particles populate the atmosphere, emerging from natural and artificial sources like volcanoes and oceans, and fossil fuels and agriculture. Ranging in size from less than ...

Computer vision helps scientists study lithium ion batteries

Lithium-ion batteries lose their juice over time, causing scientists and engineer to work hard to understand that process in detail. Now, scientists at the Department of Energy's SLAC National Accelerator Laboratory have ...
