Cryogenic Hydraulically Actuated Isolation Valve
Researchers at NASA's Marshall Space Flight Center have developed a cryogenic isolation valve that utilizes the upstream line pressure of cryogenic fluids for actuation. Previously, the use of cryogenic fluids for actuation systems had been too difficult to control and resulted in unsafe operating...

Visualizing Motion of Water Molecules for Liquid-Based Electronics
A high-resolution inelastic x-ray scattering technique was used to measure the strong bond involving a hydrogen atom sandwiched between two oxygen atoms. This hydrogen bond is a quantum-mechanical phenomenon responsible for various properties of water, including viscosity, that...
Briefs: Energy
Certain species of bacteria that exist in oxygen-deprived environments must find a way to breathe that doesn't involve oxygen. These microbes — which can be found deep within mines, at the...
