Suspended layers make a special superconductor

In superconducting materials, an electric current will flow without any resistance. There are quite a few practical applications of this phenomenon; however, many fundamental questions remain as yet unanswered. Associate ...

The sun may have a dual personality, simulations suggest

Researchers at CU Boulder have discovered hints that humanity's favorite star may have a dual personality, with intriguing discrepancies in its magnetic fields that could hold clues to the sun's own "internal clock."

The radiation showstopper for Mars exploration

An astronaut on a mission to Mars could receive radiation doses up to 700 times higher than on our planet—a major showstopper for the safe exploration of our solar system. A team of European experts is working with ESA ...

NICER's night moves trace the X-ray sky

In this image, numerous sweeping arcs seem to congregate at various bright regions. You may wonder: What is being shown? Air traffic routes? Information moving around the global internet? Magnetic fields looping across active ...

Exploring Mercury in a new book

Up until 2008, only one spacecraft had ever visited the planet Mercury, and it didn't linger long. NASA's Mariner 10 mission flew past the tiny world three times in the 1970s, giving humanity a helpful but limited glimpse ...

Improved control of big power in little motors

Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems—but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories.

Controllable fast, tiny magnetic bits

For many modern technical applications, such as superconducting wires for magnetic resonance imaging, engineers want as much as possible to get rid of electrical resistance and its accompanying production of heat.

Dellingr: the little CubeSat that could

Zipping through the sky 250 miles up is a shoebox-sized bundle of detectors and electronics named Dellingr. The namesake of the mythological Norse god of the dawn, Dellingr is among a new breed of spacecraft known as a CubeSat. ...
