MRI, on a molecular scale Friday April 18th, 2014 04:00:00 AM
(Harvard University) A team of scientists, led by professor of physics and of applied physics Amir Yacoby, have developed a magnetic resonance imaging (MRI) system that can produce nano-scale images, and may one day allow researchers to peer into the atomic structure of individual molecules.

Flipping the switch Friday April 18th, 2014 04:00:00 AM
(Harvard University) Harvard researchers have succeeded in creating quantum switches that can be turned on and off using a single photon, an achievement that could pave the way for the creation of highly secure quantum networks.

Researchers find 3-million-year-old landscape beneath Greenland ice sheet Friday April 18th, 2014 04:00:00 AM
(NASA/Goddard Space Flight Center) Glaciers and ice sheets are commonly thought to work like a belt sander. As they move over the land they scrape off everything -- vegetation, soil and even the top layer of bedrock. So a team of university scientists and a NASA colleague were greatly surprised to discover an ancient tundra landscape preserved under the Greenland ice sheet, below two miles of ice.

Sun emits a mid-level solar flare Friday April 18th, 2014 04:00:00 AM
(NASA/Goddard Space Flight Center) The sun emitted a mid-level solar flare, peaking at 9:03 a.m. EDT on April 18, 2014, and NASA's Solar Dynamics Observatory captured images of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

'Exotic' material is like a switch when super thin Friday April 18th, 2014 04:00:00 AM
(Cornell University) Researchers from Cornell University and Brookhaven National Laboratory have shown how to switch a particular transition metal oxide, a lanthanum nickelate, from a metal to an insulator by making the material less than a nanometer thick.

UT Dallas professor to develop framework to protect computers' cores Friday April 18th, 2014 04:00:00 AM
(University of Texas at Dallas) UT Dallas cybersecurity expert Dr. Zhiqiang Lin has received funding from the US Air Force to develop a defense framework that burrows deep into a computer system to protect its core.

Frozen in time: 3-million-year-old landscape still exists beneath the Greenland ice sheet Friday April 18th, 2014 04:00:00 AM
(National Science Foundation) Some of the landscape underlying the massive Greenland ice sheet may have been undisturbed for almost 3 million years, ever since the island became completely ice-covered, according to researchers funded by the National Science Foundation.

Under some LED bulbs whites aren't 'whiter than white' Friday April 18th, 2014 04:00:00 AM
(Penn State) For years, companies have been adding whiteners to laundry detergent, paints, plastics, paper and fabrics to make whites look 'whiter than white,' but now, with a switch away from incandescent and fluorescent lighting, different degrees of whites may all look the same, according to experts in lighting.

Innovative strategy to facilitate organ repair Friday April 18th, 2014 04:00:00 AM
(INSERM (Institut national de la santé et de la recherche médicale)) A significant breakthrough could revolutionize surgical practice and regenerative medicine. A team led by Ludwik Leibler from the Laboratoire Matière Molle et Chimie (CNRS/ESPCI Paris Tech) and Didier Letourneur from the Laboratoire Recherche Vasculaire Translationnelle (INSERM/Universités Paris Diderot and Paris 13), has just demonstrated that the principle of adhesion by aqueous solutions of nanoparticles can be used in vivo to repair ...

Impurity size affects performance of emerging superconductive material Friday April 18th, 2014 04:00:00 AM
(North Carolina State University) Research from North Carolina State University finds that impurities can hurt performance -- or possibly provide benefits -- in a key superconductive material that is expected to find use in a host of applications, including future particle colliders. The size of the impurities determines whether they help or hinder the material's performance.
