Chelyabinsk meteorite's rocky past: Research points to previous collision or near miss in space

Posted: 26 Aug 2013 06:56 PM PDT

Where did the Chelyabinsk meteorite come from? As a meteoroid, it either collided with another body in the solar system or came too close to the Sun before it fell to Earth, according to new research.

Molecular switch changes liquid crystal colors

Posted: 26 Aug 2013 03:31 PM PDT

Researchers have developed a molecular switch that changes a liquid crystal's readout color based on a chemical input. This new development may open the way for using liquid crystals in detecting harmful gases, pathogens, explosives and other chemical substances.

Researchers figure out how to 'grow' carbon nanotubes with specific atomic structures

Posted: 26 Aug 2013 11:38 AM PDT

Move over, silicon. In a breakthrough in the quest for the next generation of computers and materials, researchers have solved a longstanding challenge with carbon nanotubes: how to actually build them with specific, predictable atomic structures.

Size matters as nanocrystals go through phases

Posted: 26 Aug 2013 11:37 AM PDT

Researchers have demonstrated that as metal nanocrystals go through phase transformations, size can make a much bigger difference than scientists previously believed.

NASA's Spitzer telescope celebrates 10 years in space

Posted: 26 Aug 2013 10:02 AM PDT

Ten years after a Delta II rocket launched NASA's Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency's four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.

Physicist disentangles 'Schrodinger's cat' debate

Posted: 26 Aug 2013 09:30 AM PDT

A physicist that the answer to the long-running debate of quantum measurement lies in the phenomenon of nonlocality.

Rethinking investment risk

Posted: 26 Aug 2013 08:33 AM PDT

Does financial innovation inherently lead to greater risk in markets? An economist takes a new look at the problem and says it does.

Worldwide ban on flame retardant

Posted: 26 Aug 2013 07:57 AM PDT

The flame retardant HBCD may no longer be produced or used. This was decided by representatives from over 160 countries in late May at a UN conference on chemicals in Geneva. HBCD was formerly used as a flame retardant for plastics, electronics and textiles, and especially for insulation panels in buildings.

Researchers design and build the world's smallest autopilot for micro aircraft

Posted: 26 Aug 2013 06:58 AM PDT

Researchers have designed, built and tested the world's smallest open source autopilot for small unmanned aircraft. A smaller – and lighter – autopilot allows these small flying robots to fly longer, fit into narrower spaces or carry more payloads, such as cameras. That makes them more suitable to be used in for example rescue operations.

First report of real-time manipulation and control of nuclear spin noise

Posted: 26 Aug 2013 06:58 AM PDT

Physicists have demonstrated a new method for polarizing nuclear spins in extremely small samples. By monitoring and controlling spin fluctuations, the method may provide a route for enhancing the resolution of magnetic resonance imaging (MRI) on the nanometer-scale, allowing researchers to make 3D images of smaller objects than ever before.

Foldable micro electric car, Armadillo-T, unveiled

Posted: 25 Aug 2013 02:13 PM PDT

Looking for a parking space for hours at a busy shopping mall or being stuck on roads jammed with cars releasing large amounts of carbon dioxide are all-too-familiar scenes for city dwellers. A group of researchers in South Korea recently developed a possible solution to such problems: a foldable, compact electric vehicle that can be utilized either as a personal car or part of the public transit system to connect major transportation routes within a city.

UCLA researchers invent portable device for common kidney tests

Posted: 23 Aug 2013 06:13 AM PDT

A lightweight and portable device conducts kidney tests and transmits data through a cellphone attachment may significantly reduce the need for frequent office visits by diabetes patients and others with chronic kidney ailments. This device, can determine levels of albumin -- a protein commonly found in blood that is a sign of danger when found in urine -- and transmit the results within seconds.
