Human-made material pushes the bounds of superconductivity

Scientists have artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications.

SpaceX's Dragon Carrying NASA Cargo Resupplies Space Station

The Space Exploration Technologies Corp. (SpaceX) Dragon spacecraft was berthed to the International Space Station at 8:56 a.m. EST Sunday. The delivery flight was the second contracted resupply mission by the company under NASA's Commercial Resupply Services contract.

SpaceX's Dragon Launch Not Smooth But Sailing

This morning's launch of SpaceX's third Dragon capsule has the twittersphere all a-flutter. Falcon 9's blastoff from Cape Canaveral initially appeared to be a success.

Just after the Falcon 9 rocket launched around 10:10 AM EST, SpaceX CEO Elon Musk was tweeting its praises.

Falcon 9 delivered Dragon to its target orbit. All good on the rocket.

Observing impact of subtle changes in electron distribution of crystal on its atomic structure on ultrashort time scales

When a crystal is hit by an intense ultrashort light pulse, its atomic structure is set in motion.

Sound, light sources and the thrill of glimpsing the future

Scientific research is a process fraught with fits and starts, dead-ends, dashed dreams, unexpected turns, and the occasional exhilarating insight. As scientists, many of us continue along our career path in part because of those rare moments of joy felt when contributing to the frontiers of science. We experienced one of those rare moments this past January at the National Synchrotron Light Source (NSLS) X25 beamline, when we successfully tested a new method to collect data from protein crystals—by using sound waves to eject the crystals through the air into an X-ray beam.

Production of rare isotope beams with aligned nuclear spins opens up new possibilities for high-energy physics research

Particle physicists routinely and incrementally test the boundaries of what is possible in physics research. Occasionally however, they achieve a breakthrough that reveals an entirely new, uncharted field of study. Researchers at RIKEN's Radioactive Isotope Beam Factory (RIBF), part of the RIKEN Nishina Center for Accelerator-Based Science, have recently made such a breakthrough with their production of a beam of spin-aligned rare isotopes.

Turbulence in a crystal

When a crystal is hit by an intense ultrashort light pulse, its atomic structure is set in motion. Scientists can now observe how the configuration of electrons and atoms in titanium dioxide, a semiconductor, changes under the impact of an ultraviolet laser pulse, confirming that even subtle changes in the electron distribution caused by the excitation can have a considerable impact on the whole crystal structure.

Astronaut Talks Mars Exploration At Oregon State University

Stanley Love will visit Corvallis, Ore., on Monday, March 4, to talk to engineering students about the difficulties of traveling to the red planet.

NASA Begins Flight Research Campaign Using Alternate Jet Fuel

NASA researchers have begun a series of flights using the agency's DC-8 flying laboratory to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude.
