Radiation Hazards Could Make Mars Astronaut Ventures Risky

Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University of New Hampshire scientists.

Major Upgrade to Improve Quality of Cornell High Energy Synchrotron Source’s X-rays

The X-rays produced by the Cornell High Energy Synchrotron Source (CHESS) are bright, but they will soon be even brighter, thanks to a major upgrade that will make the quality of CHESS’ X-rays competitive with the world’s best synchrotron light sources.

New Theory Result Opens Up Novel Path for Generating Spin Hall Effect

Every electrical device, from a simple lightbulb to the latest microchips, is enabled by the movement of electrical charge, or current. The nascent field of ‘spintronics’ taps into a different electronic attribute, an intrinsic quantum property known as spin, and may yield devices that operate on the basis of spin-transport.

Researchers Explain Formation of Jets Emitted by Young Stars

Using a patented experimental device and supercomputer simulations, researchers have managed to explain the formation of jets emitted by young stars. In perfect agreement with astrophysical observations, the model, which involves the interstellar magnetic field, was developed by an international collaboration1 led by French teams at the Laboratoire pour l'Utilisation des Lasers Intenses (LULI, CNRS/École Polytechnique/UPMC/CEA), the Laboratoire d'Etudes du Rayonnement et de la Matière en Astrophysique et atmosphères (LERMA, Observatoire de Paris/CNRS/UPMC/Université de Cergy-Pontoise/ENS Paris) and the Laboratoire National des Champs Magnétiques Intenses (LNCMI, CNRS). Their work is published in the 17 October 2014 issue of the journal Science.

MIT Develops Circuit Design for Cheaper Manufacture of Simple Superconducting Devices

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive data centers that power the Internet's most popular sites.

New Quantum Mechanics Technique to Get Photons into Shape

CQT's quantum mechanics have performed a new feat to get photons – the particles of light – into shape. The technique could prove useful for building devices that shuttle information between photons and atoms and back again. The work is described in a 15 October paper in Physical Review Letters, highlighted by the journal as an Editors' Suggestion.
