| Holiday asteroid imaged with NASA radar Posted: 21 Dec 2018 01:22 PM PST The December 2018 close approach by the large, near-Earth asteroid 2003 SD220 has provided astronomers an outstanding opportunity to obtain detailed radar images of the surface and shape of the object and to improve the understanding of its orbit. |
| The coolest experiment in the universe Posted: 21 Dec 2018 01:18 PM PST NASA's Cold Atom Laboratory on the International Space Station is the first facility in orbit to produce clouds of "ultracold" atoms, which can reach a fraction of a degree above absolute zero. Nothing in nature is known to hit the temperatures achieved in laboratories like CAL, which means the orbiting facility is regularly the coldest known spot in the universe. |
| NASA's InSight places first instrument on Mars Posted: 21 Dec 2018 01:16 PM PST NASA's InSight lander has deployed its first instrument onto the surface of Mars, completing a major mission milestone. New images from the lander show the seismometer on the ground, its copper-colored covering faintly illuminated in the Martian dusk. |
| Posted: 21 Dec 2018 11:25 AM PST Researchers have developed a soft, non-toxic wearable sensor that unobtrusively attaches to the hand and measures the force of a grasp and the motion of the hand and fingers. |
| Electric fish in augmented reality reveal how animals 'actively sense' world around them Posted: 21 Dec 2018 09:39 AM PST Researchers have used augmented reality technology to unravel the mysterious dynamic between active sensing movement and sensory feedback. |
| Posted: 21 Dec 2018 09:38 AM PST Researchers have developed metasurfaces with extreme angle-asymmetric response. The new device can be a good or bad reflector depending on the angle the light hits it. |
| Description of rotating molecules made easy Posted: 21 Dec 2018 09:38 AM PST By turning highly complex equations into sets of simple diagrams, Feynman diagrams have established themselves as one of the sharpest tools in a theoretical physicist's toolbox. Scientists have now extended the technique: originally devised for subatomic particles, the simplest objects imaginable, the technique can now work with molecules. The research is expected to drastically simplify the description of molecular rotations in solvents. |
| Looking at molecules from two sides with table-top femtosecond soft-X-rays Posted: 21 Dec 2018 09:38 AM PST Researchers have successfully combined a table-top laser-based extreme high-order harmonic source for short-pulse soft-X-ray absorption spectroscopy in the water window with novel flatjet technology. They are the first to demonstrate the simultaneous probing of carbon and nitrogen atoms in organic molecules in aqueous solution. |
| Strong interactions produce a dance between light and sound Posted: 21 Dec 2018 09:38 AM PST Light and high-frequency acoustic sound waves in a tiny glass structure can strongly couple to one another and perform a dance in step. |
| Quantum tricks to unveil the secrets of topological materials Posted: 21 Dec 2018 09:38 AM PST 'Topological materials' produce electron states that can be very interesting for technical applications, but it is extremely difficult to identify these materials and their associated electronic states. A 'crystal' made of light waves can now be used to deliberately drive the system out of equilibrium. By switching between simple and complicated states, the system reveals whether or not it has topologically interesting states. |
| Turbulence in exceptionally hot solar corona Posted: 21 Dec 2018 09:37 AM PST Astrophysicists are keen to learn why the corona is so hot. Scientists have completed research that may advance the search. |
| Artificial intelligence system learns to diagnose, classify intracranial hemorrhage Posted: 21 Dec 2018 09:37 AM PST A team of investigators has developed a system using artificial intelligence to quickly diagnose and classify brain hemorrhages and to provide the basis of its decisions from relatively small image datasets. |
| Twisting light to enable high-capacity data transmission Posted: 21 Dec 2018 09:37 AM PST For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. Because germanium is compatible with the silicon used to make computer chips, the new light source could be used to boost the amount of data that can be transmitted with chip-based optical computing and communication. |
| Baby star's fiery tantrum could create the building blocks of planets Posted: 21 Dec 2018 09:37 AM PST A massive stellar flare on a baby star has been spotted by astronomers, shedding light on the origins of potentially habitable exoplanets. |
| Lean electrolyte design is a game-changer for magnesium batteries Posted: 21 Dec 2018 09:37 AM PST Researchers have discovered a promising new version of high-energy magnesium batteries, with potential applications ranging from electric vehicles to battery storage for renewable energy systems. |
| Bees can count with small number of nerve cells in their brains, research suggests Posted: 21 Dec 2018 09:37 AM PST Bees can solve seemingly clever counting tasks with very small numbers of nerve cells in their brains, according to researchers. |
| Droughts boost emissions as hydropower dries up Posted: 21 Dec 2018 09:36 AM PST Recent droughts caused increases in emissions of carbon dioxide and harmful air pollutants from power generation in several western states as fossil fuels came online to replace hampered hydroelectric power. A new study quantifies the impact. |
| Researchers monitor electron behavior during chemical reactions for the first time Posted: 21 Dec 2018 09:36 AM PST Researchers demonstrated their ability to observe electrons' movements during a chemical reaction. |
| NASA telescopes take a close look at the brightest comet of 2018 Posted: 20 Dec 2018 01:32 PM PST As the brilliant comet 46P/Wirtanen streaked across the sky, NASA telescopes caught it on camera from multiple angles. |
| New AI computer vision system mimics how humans visualize and identify objects Posted: 20 Dec 2018 01:32 PM PST Researchers have demonstrated a computer system that can discover and identify the real-world objects it 'sees' based on the same method of visual learning that humans use. |
| 3D-printed robot hand plays the piano Posted: 20 Dec 2018 01:32 PM PST Scientists have developed a 3D-printed robotic hand which can play simple musical phrases on the piano by just moving its wrist. And while the robot is no virtuoso, it demonstrates just how challenging it is to replicate all the abilities of a human hand, and how much complex movement can still be achieved through design. |
| Chemists create new quasicrystal material from nanoparticle building blocks Posted: 20 Dec 2018 11:11 AM PST Brown University researchers have discovered a new type of quasicrystal, a class of materials whose existence was thought to be impossible until the 1980s. |
| Chloroform emissions could delay ozone recovery by up to 8 years Posted: 20 Dec 2018 08:17 AM PST A new study identifies another threat to the ozone layer's recovery: chloroform -- a colorless, sweet-smelling compound that is primarily used in the manufacturing of products such as Teflon and various refrigerants. The researchers found that between 2010 and 2015, emissions and concentrations of chloroform in the global atmosphere have increased significantly. |
| Hardware-software co-design approach could make neural networks less power hungry Posted: 19 Dec 2018 04:11 PM PST Engineers have developed a neuroinspired hardware-software co-design approach that could make neural network training more energy-efficient and faster. Their work could one day make it possible to train neural networks on low-power devices such as smartphones, laptops and embedded devices. |
