Stacking 2-D materials produces surprising results

New experiments reveal previously unseen effects, could lead to new kinds of electronics and optical devices.

New method proposed for detecting gravitational waves from ends of universe

A new window into the nature of the universe may be possible with a device proposed by scientists that would detect elusive gravity waves from the other end of the cosmos.

Carbon in a twirl: The science behind a self-assembled nano-carbon helix

Nanotechnology draws on the fabrication of nanostructures. Scientists have now succeeded in growing a unique carbon structure at the nanoscale that resembles a tiny twirled mustache. Their method might lead the way to the formation of more complex nano-networks.

IceCube Neutrino Observatory reports first evidence for extraterrestrial high-energy neutrinos

(Phys.org) —A massive telescope in the Antarctic ice reports the detection of 28 extremely high-energy neutrinos that might have their origin in cosmic sources. Two of these reached energies greater than 1 petaelectronvolt (PeV), an energy level thousands of times higher than the highest energy neutrino yet produced in a manmade accelerator.

NASA's Asteroid Sample Return Mission Moves into Development

NASA's first mission to sample an asteroid is moving ahead into development and testing in preparation for its launch in 2016.

NASA Satellite Data Help Pinpoint Glaciers' Role in Sea Level Rise

A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise.

NASA Extends Environmental Testing and Integration Services Contract at Goddard

NASA has extended a contract with Analex Corporation of Fairfax, Va., for Environmental Testing and Integration Services at the agency's Goddard Space Flight Center in Greenbelt, Md.

RUB physicists let magnetic dipoles interact on the nanoscale for the first time

Physicists at the Ruhr-Universität Bochum (RUB) have found out how tiny islands of magnetic material align themselves when sorted on a regular lattice - by measurements at BESSY II. Contrary to expectations, the north and south poles of the magnetic islands did not arrange themselves in a zigzag pattern, but in chains.
