| Physicists detect a hybrid particle held together by uniquely intense 'glue' Posted: 10 Jan 2022 03:49 PM PST Physicists detected a hybrid particle that is a mashup of an electron and a phonon, 'glued' together with an exceptionally strong bond. It may be possible to tune the two components in tandem, enabling scientists to apply voltage or light to a material to tune not just its electrical properties but also its magnetism. |
| Personalizing treatment for severe limb injuries Posted: 10 Jan 2022 11:53 AM PST Scientists have developed an innovative technique using small wearable sensors to gather data on how people -- who have suffered from a traumatic hand amputation -- use a prothesis versus a transplanted hand in everyday life. So far, the data shows people with a transplanted hand demonstrate a more balanced use of their hands than those who use a prothesis. |
| Gauging the resilience of complex networks Posted: 10 Jan 2022 10:27 AM PST Whether a transformer catches fire in a power grid, a species disappears from an ecosystem, or water floods a city street, many systems can absorb a certain amount of disruption. But how badly does a single failure weaken the network? And how much damage can it take before it tips into collapse? |
| Astronomers identify potential clue to reinonization of universe Posted: 10 Jan 2022 08:41 AM PST Astronomers have identified a potential clue to how the universe became reionized after the Big Bang. The researchers identified a black hole, a million times as bright as our sun, that may have been similar to the sources that powered the universe's reionization. |
| Ocean physics explain cyclones on Jupiter Posted: 10 Jan 2022 08:41 AM PST Images from NASA's June Spacecraft have given oceanographers the raw materials for a new study that describes the rich turbulence at Jupiter's poles and the physical forces that drive the large cyclones. |
| Chemists use DNA to build the world’s tiniest antenna Posted: 10 Jan 2022 07:33 AM PST An easy-to-use device promises to help scientists better understand natural and human-designed nanotechnologies -- and identify new drugs. |
| Will this new superpower molecule revolutionize science? Posted: 10 Jan 2022 07:32 AM PST Researchers report the creation of an artificial molecule with superpowers. It has the potential to revolutionize nanotechnology -- and it also explains one of Nature's intriguing enigmas; why do we have a right hand and a left hand? The researchers describe their supermolecule as a marriage between DNA and peptides. |
| Catalyst surface analysed at atomic resolution Posted: 10 Jan 2022 07:32 AM PST A research team has visualized the three-dimensional structure of the surface of catalyst nanoparticles at atomic resolution. This structure plays a decisive role in the activity and stability of the particles. The detailed insights were achieved with a combination of atom probe tomography, spectroscopy and electron microscopy. Nanoparticle catalysts can be used, for example, in the production of hydrogen for the chemical industry. To optimize the performance of future catalysts, it is essential to understand how it is affected by the three-dimensional structure. |
| Scientists reduce all-solid-state battery resistance by heating Posted: 07 Jan 2022 05:44 AM PST All-solid-state batteries are now one step closer to becoming the powerhouse of next-generation electronics as researchers introduce a strategy to restore their low electrical resistance. They also explore the underlying reduction mechanism, paving the way for a more fundamental understanding of the workings of all-solid-state lithium batteries. |
| High levels of PFAS found in anti-fogging sprays and cloths, study finds Posted: 05 Jan 2022 06:45 AM PST The anti-fogging sprays and cloths many people use to prevent condensation on their eyeglasses when wearing a mask or face shield may contain high levels of per- and polyfluorinated alkyl substances (PFAS), a new study finds. |
| Coughing downward reduces spread of respiratory droplets, study finds Posted: 04 Jan 2022 08:58 AM PST Researchers show models driving how respiratory droplets fell from a mannequin inside a water tunnel, which was inclined at different angles to mimic a person going up and down stairs. Using glass microspheres and lasers, they could visualize the flow motion behind the mannequins. |
