Spiral laser beam creates quantum whirlpool

November 17, 2014 10:24 am | by Australian National Univ. | News | Comments

Physicists at Australian National Univ. have engineered a spiral laser beam and used it to create a whirlpool of hybrid light-matter particles called polaritons. The ability to control polariton flows in this way could aid the development of completely novel technology to link conventional electronics with new laser and fiber-based technologies.

Efficient method developed to measure residual stress in 3-D printed parts

November 17, 2014 10:08 am | by Kenneth Ma, LLNL | News | Comments

Lawrence Livermore National Laboratory researchers have developed an efficient method to measure residual stress in metal parts produced by powder-bed fusion additive manufacturing. This 3-D printing process produces metal parts layer by layer using a high-energy laser beam to fuse metal powder particles.

Study suggests genetic link for male homosexuality

November 17, 2014 10:01 am | by Lindsey Tanner - AP Medical Writer - Associated Press | News | Comments

A large study of gay brothers adds to evidence that genes influence men's chances of being homosexual, but the results aren't strong enough to prove it. Some scientists believe several genes might affect sexual orientation. Researchers who led the new study of nearly 800 gay brothers say their results bolster previous evidence pointing to genes on the X chromosome.

Motor/Stream Selector for OEM Applications

November 17, 2014 9:51 am | Product Releases | Comments

VICI Valco’s Cheminert C65 Series liquid handling stream selector is an integrated motor/valve assembly designed specifically to be built into an OEM system. Using the Cheminert LC valve design and the 24-V motor from the company’s microelectric actuators, the C65 needs only to be connected to the instruments power supply.

Enclosures for Robotics, Laboratory Automation

November 17, 2014 9:43 am | Hemco Corporation | Product Releases | Comments

HEMCO Enclosures are designed to enclose robots and other laboratory automated processes by providing exhaust air systems or HEPA filtered clean workstations. Robots are beneficial in many applications, and are proven to increase efficiency and productivity.

Hand transplant research sheds light on touch

November 17, 2014 8:52 am | by Associated Press, Lauran Neergaard | News | Comments

Recovery of feeling can gradually improve for years after a hand transplant, suggests a small study that points to changes in the brain, not just the new hand, as a reason. Research presented at a meeting of the Society for Neuroscience sheds light on how the brain processes the sense of touch, and adapts when it goes awry. The work could offer clues to rehabilitation after stroke, brain injury, maybe one day even spinal cord injury.

Artificial intelligence magic tricks

November 17, 2014 8:46 am | by Queen Mary Univ. of London | Videos | Comments

Researchers from the Queen Mary Univ. of London gave a computer program the outline of how a magic jigsaw puzzle and a mind-reading card trick work, as well the results of experiments into how humans understand magic tricks, and the system created completely new variants on those tricks which can be delivered by a magician.

New method for methanol processing could reduce carbon dioxide emissions

November 17, 2014 8:33 am | by Matthew Chin, Univ. of California, Los Angeles | News | Comments

Researchers at the Univ. of California, Los Angeles Henry Samueli School of Engineering and Applied Science have developed a more efficient way to turn methanol into useful chemicals, such as liquid fuels, and that would also reduce carbon dioxide emissions. Methanol, which is a product of natural gas, is well-known as a common “feedstock” chemical.

Lighting the way for future electronic devices

November 17, 2014 8:15 am | by Univ. of Southampton | News | Comments

Researchers at the Univ. of Southampton have demonstrated how glass can be manipulated to create electronic devices that will be smaller, faster and consume less power. The researchhas the potential to allow faster, more efficient electronic devices; further shrinking the size of our phones, tablets and computers and reducing their energy consumption by turning waste heat into power.

Researchers discern the shapes of high-order Brownian motions

November 17, 2014 7:57 am | by Case Western Reserve Univ. | News | Comments

For the first time, scientists have vividly mapped the shapes and textures of high-order modes of Brownian motions—in this case, the collective macroscopic movement of molecules in microdisk resonators—researchers at Case Western Reserve Univ. report. To do this, they used a record-setting scanning optical interferometry technique.

Motion-induced quicksand

November 17, 2014 7:45 am | by Jennifer Chu, MIT News Office | News | Comments

From a mechanical perspective, granular materials are stuck between a rock and a fluid place, with behavior resembling neither a solid nor a liquid. Think of sand through an hourglass: As grains funnel through, they appear to flow like water, but once deposited, they form a relatively stable mound, much like a solid.

Heart stents may require longer blood thinner use

November 16, 2014 5:00 pm | by Marilynn Marchione - AP Chief Medical Writer - Associated Press | News | Comments

Millions of people with stents that prop open clogged heart arteries may need anti-clotting drugs much longer than the one year doctors recommend now. A large study found that continuing for another 18 months lowers the risk of heart attacks, clots and other problems. Even quitting after 30 months made a heart attack more likely, raising a question of when it's ever safe to stop.

Evolution of NIR Spectroscopy: Past, Present and Future

November 14, 2014 4:04 pm | by Joe Siddall, TI DLP Embedded Products Program Manager | Articles | Comments

Near-infrared (NIR) spectrometers have been around for over 60 years, yet only a small fraction of the population is familiar with these dependable tools. It’s astounding that NIR spectroscopy does so much for so many people who have never heard the word “spectrometer.” NIR spectrometers help a diverse set of users make decisions in their daily jobs.

LLNL, IBM to deliver next-generation supercomputer

November 14, 2014 11:01 am | by Lynda L. Seaver, Lawrence Livermore National Laboratory | News | Comments

Lawrence Livermore National Laboratory (LLNL) announced a contract with IBM to deliver a next-generation supercomputer in 2017. The system, to be called Sierra, will serve the National Nuclear Security Administration’s Advanced Simulation and Computing program. Procurement of Sierra is part of a DOE-sponsored Collaboration of Oak Ridge, Argonne and Lawrence Livermore national labs to accelerate the development of high-performance computing.

Smartphone app to cut risk of power outages

November 14, 2014 10:45 am | by Carl Blesch, Rutgers Univ. | News | Comments

An easy-to-use smartphone app developed by Rutgers Univ. engineers will help keep the lights on in a heavily wooded New Jersey suburb that suffered widespread power outages during Superstorm Sandy. The smartphone app walks users through documenting hazards, such as branches dangling perilously close to wires or poles cracking and leaning.
