Blasting molecules with extreme X-rays

Reading these words, your eyes let you see each letter and the spaces between them. But if you need reading glasses, the letters may be fuzzy or incomprehensible. Scientists face a similar challenge. Gathering the right data depends on having tools that can provide accurate, comprehensive measurements. After all, scientists want to have the clearest sight possible.

Coverage Set for Russian Spacewalk at International Space Station

Two Russian cosmonauts will venture outside the International Space Station at 11 a.m. EST Tuesday, Dec. 11, to conduct a six-hour spacewalk.

NASA Highlights Asteroid Bennu, Earth’s Polar Ice at AGU Meeting

NASA researchers will present new findings on a wide range of Earth and space science topics at the annual meeting of the American Geophysical Union (AGU), Dec. 10-14 in Washington.

A 3D imaging technique unlocks properties of perovskite crystals

Materials scientists have, for the first time, visualized the 3D atomic and electron density structure of the most complex perovskite crystal structure system decoded to date.

Capturing spray from flash-boiling liquid jets

Ultrafast video capture of droplet cloud formation should help minimize the risk of gas-leak explosions.

Technique inspired by dolphin chirps could improve tests of soft materials

When you deform a soft material such as Silly Putty, its properties change depending on how fast you stretch and squeeze it. If you leave the putty in a small glass, it will eventually spread out like a liquid. If you pull it slowly, it will thin and droop like viscous taffy. And if you quickly yank on it, the Silly Putty will snap like a brittle, solid bar.

Reflecting antiferromagnetic arrangements

An X-ray imaging technique could help scientists understand -- and ultimately control -- the magnetic structure of promising materials for the development of electronic devices that exploit electron spin.

On the trail of the Higgs Boson

In a quest to understand the production mechanisms for the Higgs Boson, a researcher has investigated the traces of a rare process, called ttH, in which the Higgs Boson is produced in association with a pair of elementary particles referred to as top quarks.

COSINE-100 experiment investigates dark matter mystery

A new international experiment challenges previous claims about the detection of non-luminous dark matter.

NASA Sends New Research, Hardware to Space Station on SpaceX Mission

Experiments in forest observation, protein crystal growth and in-space fuel transfer demonstration are heading to the International Space Station following the launch Wednesday of SpaceX’s 16th mission for NASA under the agency’s Commercial Resupply Services contract.
