NASA Administrator Statement on Alpha Magnetic Spectrometer

The following is a statement from NASA Administrator Charles Bolden on the first Alpha Magnetic Spectrometer (AMS) results announced Wednesday at the European Organization for Nuclear Research (CERN) in Switzerland. AMS is a cosmic ray particle physics detector on the exterior of the International Space Station.

NASA Flies Radar South on Wide-Ranging Scientific Expedition

A versatile NASA airborne imaging radar system is showcasing its broad scientific prowess for studying our home planet during a month-long expedition over the Americas.

Media Invited to NASA Commercial Partner New Rocket Rollout April 6

News media are invited to cover the scheduled Saturday, April 6, morning rollout of Orbital Sciences Corporation's Antares launch vehicle to the Mid-Atlantic Regional Spaceport's Pad-0A at NASA's Wallops Flight Facility on Wallops Island, Va.

Quarks' spins dictate their location in the proton

A successful measurement of the distribution of quarks that make up protons conducted at DOE's Jefferson Lab has found that a quark's spin can predict its general location inside the proton. Quarks with spin pointed in the up direction will congregate in the left half of the proton, while down-spinning quarks hang out on the right. The research also confirms that scientists are on track to the first-ever three-dimensional inside view of the proton.

Spintronics: Researching ways to improve computer speed, efficiency

(Phys.org) —Remember when each new crop of computers was ever so much faster than the previous models? Well, those good-old days ended about five years ago when the accelerating rate of computing speeds crashed into the impenetrable wall of fundamental physics. The problem, according to Penn State Professor of Physics Nitin Samarth, involves electricity—specifically, the way computer components called transistors use electricity to compute.

Physics makes a big impact in brain-injury research

From battlefields to playing fields, worries over traumatic brain injury (TBI) have intensified recently as it has become clear that heavy knocks to the head – whether from bomb detonations or crunching sports tackles – can have serious long-term consequences.

Phase transition may explain how brain neurons encode information

(Phys.org) —While scientists know that information is represented in the brain by the electrical activity of neurons, the details of this representation, called "neural coding," remain mysterious. How exactly do pulses of electricity get translated into thoughts and ideas?
