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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
