| 'Bionic' pacemaker reverses heart failure Posted: 07 Feb 2022 02:29 PM PST A revolutionary pacemaker that re-establishes the heart's naturally irregular beat is set to be trialled in New Zealand heart patients this year. |
| Beyond sci-fi: Manipulating liquid metals without contact Posted: 07 Feb 2022 02:29 PM PST Research inspired by Terminator 2's shape-shifting, liquid metal robot sees liquid-metal electrical conductors manipulated in mid-air without contact. The liquid wires can be controlled to move in any direction, and manipulated into unique, levitated shapes such as loops and squares using a small 'triggering' voltage and a magnet. The new technology has potential application in advanced manufacturing and dynamic electronic structures, augmenting other non-contact manipulation technologies such as acoustics or optical tweezers. |
| Research team's mask strategy passes muster Posted: 07 Feb 2022 12:57 PM PST During the early stages of the COVID-19 pandemic, a research team went looking for and found a way to make standard surgical masks better at keeping out small airborne droplets that might contain the SARS-CoV-2 virus. |
| Mechanical hearts can regenerate some heart tissue Posted: 07 Feb 2022 12:56 PM PST Mechanical hearts spur some regeneration in dormant parts of failing hearts, according to a pilot study that shows promise for developing regenerative heart therapies. |
| Researchers use tiny magnetic swirls to generate true random numbers Posted: 07 Feb 2022 09:48 AM PST Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing. |
| Jet stream models help inform US offshore wind development Posted: 07 Feb 2022 09:48 AM PST With the federal government planning to hold the largest sale of offshore wind farm leases in the nation's history, a new study could help inform the development of offshore wind farms by providing detailed models characterizing the frequency, intensity and height of low-level jet streams over the U.S. Atlantic coastal zone. |
| Nanowires under tension create the basis for ultrafast transistors Posted: 07 Feb 2022 08:26 AM PST Nanowires have a unique property: These ultra-thin wires can sustain very high elastic strains without damaging the crystal structure of the material. A team of researchers has now succeeded in experimentally demonstrating that electron mobility in nanowires is remarkably enhanced when the shell places the wire core under tensile strain. |
| Protons are probably actually smaller than long thought Posted: 06 Feb 2022 12:44 PM PST A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard Model of particle physics would have to be changed. Physicists have now developed a method that allows them to analyze the results of older and more recent experiments much more comprehensively than before. This also results in a smaller proton radius from the older data. So there is probably no difference between the values - no matter which measurement method they are based on. |
