| 'E-nose' could someday diagnose Parkinson's disease by 'smelling' skin Posted: 23 Feb 2022 05:58 AM PST Scientists have been trying to build devices that could diagnose Parkinson's disease (PD) through odor compounds on the skin. Now, researchers have developed a portable, artificially intelligent olfactory system, or 'e-nose,' that could someday diagnose the disease in a doctor's office. |
| Galaxy collision creates 'space triangle' in new Hubble image Posted: 23 Feb 2022 05:58 AM PST A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA's Hubble Space Telescope. |
| 'Tatooine-like' exoplanet spotted by ground-based telescope Posted: 23 Feb 2022 05:58 AM PST A rare exoplanet which orbits around two stars at once has been detected using a ground-based telescope. The planet, called Kepler-16b, has so far only been seen using the Kepler space telescope. It orbits around two stars, with the two orbits also orbiting one another, forming a binary star system. |

| Detecting stressed-out polymer films, gels before they break Posted: 23 Feb 2022 05:55 AM PST Stretchy films and squishy gels help make wearable electronics, soft robotics and biocompatible tissues a reality. But too much force can cause these polymers to break apart without warning. To detect stress before it's too late, researchers show they have designed a compound with 'wings' that makes these materials change color when they are stretched or crushed. |
| Tiny probes could sail to outer planets with the help of low-power lasers Posted: 23 Feb 2022 05:54 AM PST Space travel can be agonizingly slow: For example, the New Horizons probe took almost 10 years to reach Pluto. Traveling to Proxima Centauri b, the closest habitable planet to Earth, would require thousands of years with even the biggest rockets. Now, researchers calculate that low-power lasers on Earth could launch and maneuver small probes equipped with silicon or boron nitride sails, propelling them to much faster speeds than rocket engines. |
| Better understanding communication between neurons in the brain Posted: 22 Feb 2022 10:54 AM PST Researchers have developed a new method for controlled interrogation and recording of neuronal activity. The system combines technology from multichannel optogenetics with laminar recordings in the brain. The research team proposes alternative design for silicon probes and develops fibers with a Lambertian emission. |
| Evidence for exotic magnetic phase of matter Posted: 22 Feb 2022 10:54 AM PST Scientists have discovered a long-predicted magnetic state of matter called an antiferromagnetic excitonic insulator -- broadly speaking, a novel type of magnet. Understanding the connections between electrons' 'spin' and charge in such materials could have potential for realizing new technologies. |
| Monitoring Arctic permafrost with satellites, supercomputers, and deep learning Posted: 22 Feb 2022 10:54 AM PST Using deep learning and supercomputers, researchers have been able to identify and map 1.2 billion ice wedge polygons in the Arctic permafrost based on satellite imagery. The data helps establish a baseline from which to detect changes to the region. The researchers trained a deep learning system to identify Arctic features and TACC's Longhorn supercomputer to analyze the data. The ice wedge data will be available for rapid analysis on the new Permafrost Discovery Gateway. |
| Light-based device uses a few drops of saliva to effectively test COVID-19 patients Posted: 22 Feb 2022 10:54 AM PST Researchers report on the development of a low-cost, portable, non-invasive device that uses light and saliva to test COVID-19 patients in less than 30 minutes. The results have shown that the device can detect very low concentrations of SARS-CoV-2 with a sensitivity of 91.2 percent and a specificity of 90 percent, similar to that of PCR but as fast as an antigen test. |
| Carbon dioxide recycling and efficient drug development -- tackling two problems with one reaction Posted: 22 Feb 2022 10:54 AM PST Using electricity, a new method offers the possibility of recycling carbon dioxide while also performing a notoriously difficult reaction, producing compounds potentially useful for drug development. |
| Ushering in safe, low-carbon electricity generated by nuclear fusion Posted: 22 Feb 2022 10:54 AM PST Engineers are working to develop a new, economically viable and safe source of low carbon electricity through nuclear fusion. |
| New technology fused with photosynthetic life offers path to green energy Posted: 22 Feb 2022 10:53 AM PST Researchers have developed a patented hybrid device -- part living organism, part bio battery, capable of producing stored energy by increasing energy flow under light conditions where natural photosynthesis is normally inhibited. |
| Insect wingbeats will help quantify biodiversity Posted: 22 Feb 2022 10:52 AM PST Insect populations are plummeting worldwide, with major consequences for our ecosystems and without us quite knowing why. A new AI method is set to help monitor and catalog insect biodiversity, which until now has been quite challenging. |
| What ingredients went into the galactic blender to create the Milky Way? Posted: 22 Feb 2022 10:52 AM PST In its early days, the Milky Way was like a giant smoothie, as if galaxies consisting of billions of stars, and an enormous amount of gas had been thrown together into a gigantic blender. But a new study picks apart this mixture by analyzing individual stars to identify which originated inside the galaxy and which began 'life' outside. |
| 290 million new city dwellers benefit China's climate balance Posted: 22 Feb 2022 10:52 AM PST Contrary to popular belief, China's massive emigration from rural areas to cities has been shown to have a positive effect on China's carbon stocks. Urbanization can even play a role in attaining climate neutrality. This is the conclusion of researchers based upon analyses of vast amounts of satellite data. |
| Molecule snapshot by explosion Posted: 22 Feb 2022 10:51 AM PST An international team of scientists has taken a snapshot of a cyclic molecule using a novel imaging method. Researchers used the world's largest X-ray laser to explode the molecule iodopyridine in order to construct an image of the intact molecule from the resulting fragments. |
| Physicists harness electrons to make 'synthetic dimensions' Posted: 22 Feb 2022 10:51 AM PST Physicists have learned to manipulate electrons in gigantic Rydberg atoms with such precision they can create 'synthetic dimensions' where the system acts as if it had extra spatial dimensions, which are important tools for quantum simulations. |

| Fish generate movable pairs of vortices to propel them forward like body waves Posted: 22 Feb 2022 09:12 AM PST Researchers show that fish, through precise control of body fluctuations, generate movable vortex pairs of high- and low-pressure regions that enable them to swim. They used particle image velocimetry and high-speed cameras to analyze the spontaneous swimming of zebrafish in a tank, and the findings provide the groundwork in the design of flexible structures for a high-performance underwater bionic propeller. |
