Fourth-generation wire micrometer that rivals best in the world

Researchers at the National Institute of Standards and Technology (NIST) have developed a dramatically improved laser-based instrument that measures the diameter of fine-gauge wires, fibers and other objects only about three ...

Old X-rays, new vision: A nano-focused X-ray laser

Imagine taking movies of the fastest chemical processes, or imaging atomic-scale detail of single virus particles without damaging them. Researchers from Japan have advanced the state-of-the-art in such endeavors, by enhancing ...

Impacts on asteroids produce regolith, erase small craters

Impact cratering both produces new regolith and causes seismic events that can degrade and erase small craters on the surface of asteroids, a paper by Planetary Science Institute Senior Scientist James Richardson says. 

Image: ESA's Large Diameter Centrifuge at full speed

ESA's Large Diameter Centrifuge at the Agency's technical heart in the Netherlands is seen running here at full speed. The 8-m diameter four-arm centrifuge gives researchers access to a range of hypergravity environments ...

Asteroids help scientists measure distant stars

Look up at the sky on a clear night, and you'll see lots of stars. Sometimes they seem almost within reach or at least a short rocket ride. But the closest star to Earth—not counting our sun—is more than four light years ...

Magnetic nanoparticles can 'burn' cancer cells

Unfortunately, cancer isn't simply a single disease, and some types, like pancreas, brain or liver tumours, are still difficult to treat with chemotherapy, radiation therapy or surgery, leading to low survival rates for patients. ...
