NASA Announces 2013 Space Technology Research Grants

NASA has selected 65 graduate students as the 2013 class of Space Technology Research Fellows.

Carbon nanotubes for molecular magnetic resonances

Researchers have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results open the door for magnetic resonance imaging of individual molecules.

Computer simulations shed light on how immune cells identify foreign antigens

How do immune cells manage to sort through vast numbers of similar-looking proteins within the body to detect foreign invaders and fight infections? McGill researchers used computational tools to examine what kind of solutions immune systems may use to detect small concentrations of foreign antigens (characteristic of potentially harmful infections) in a sea of "self-antigens" normally present at the surface of cells.

'Long-awaited explanation' for mysterious effects in high-temperature superconductors

A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain temperature, superconductors lose their electrical resistance and can conduct electricity without loss.

Whispering light hears liquids talk

Researchers have developed optomechanical sensors in which extremely minute forces exerted by light are used to generate and control high-frequency mechanical vibrations of microscale and nanoscale devices that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.

Whispering light hears liquids talk: Scientists build first-ever bridge between optomechanics and microfluidics

Ever been to a whispering gallery—a quiet, circular space underneath an old cathedral dome that captures and amplifies sounds as quiet as a whisper? Researchers at the University of Illinois at Urbana-Champaign are applying similar principles in the development optomechanical sensors that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.

NASA Selects New Suborbital Payloads, Total Tops 100 Experiments

NASA has selected 21 space technology payloads for flights on commercial reusable launch vehicles, balloons, and a commercial parabolic aircraft.

Spooky action put to order: Different types of 'entanglement' classified

A property known as "entanglement" is a fundamental characteristic of quantum mechanics. Physicists and mathematicians have now shown how different forms of this phenomenon can be efficiently and systematically classified into categories. The method should help to fully exploit the potential of novel quantum technologies.

Quantum teleportation between atomic systems over long distances

Researchers have been able to teleport information from light to light at a quantum level for several years. In 2006, researchers succeeded in teleporting between light and gas atoms. Now the research group has succeeded in teleporting information between two clouds of gas atoms and to carry out the teleportation -- not just one or a few times, but successfully every single time.

“Dust Trap” Solves Mystery of Planet Formation

It’s always sobering to remember how much we still don’t know about the universe. Despite finding hundreds of exoplanetary systems and numerous stars surrounded by proto-planetary disks of gas and dust, it’s still not clear how the latter become the former. But observations by the recently-opened Atacama Large Millimeter/submillimeter Array (ALMA) have shed light on this question by finding a “safe haven” for growing pre-planets around a relatively nearby star.
