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 ...

After 90 years, a better way to measure the composition of paper

Researchers at the National Institute of Standards and Technology (NIST), in collaboration with the U.S. Government Publishing Office (GPO), have developed a novel, nondestructive method to rapidly measure the wood and non-wood ...

Lightning's electromagnetic fields may have protective properties

Lightning was the main electromagnetic presence in the Earth's atmosphere long before the invention of electricity. There are some 2,000 thunderstorms active at any given time, so humans and other organisms have been bathed ...

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; ...

Artificial skin could give superhuman perception

A new type of sensor could lead to artificial skin that someday helps burn victims 'feel' and safeguards the rest of us, University of Connecticut researchers suggest in a forthcoming paper in Advanced Materials.

Optimizing electric fields yields better catalysts

Industries rely on catalysts. These materials lessen the energy used in refining oil, manufacturing plastics, and much more. Catalysts can also mean less waste is produced. Better catalysts would benefit industries and the ...
