| COVID-19 lockdowns temporarily raised global temperatures, research shows Posted: 02 Feb 2021 01:45 PM PST The lockdowns and reduced societal activity related to the COVID-19 pandemic affected emissions of pollutants in ways that slightly warmed the planet for several months last year, according to new research. The counterintuitive finding highlights the influence of airborne particles, or aerosols, that block incoming sunlight. |
| An origami-inspired medical patch for sealing internal injuries Posted: 02 Feb 2021 01:45 PM PST Engineers have designed an origami-inspired medical patch for minimally invasive sealing of internal injuries, which could also be used in robotic surgery for remote repair of damaged tissues and organs. |
| Highly deformable piezoelectric nanotruss for tactile electronics Posted: 02 Feb 2021 08:38 AM PST A research team confirmed the potential of tactile devices by developing ceramic piezoelectric materials that are three times more deformable. For the fabrication of highly deformable nanomaterials, the research team built a zinc oxide hollow nanostructure using proximity field nanopatterning and atomic layered deposition. |
| Venus flytraps found to produce magnetic fields Posted: 02 Feb 2021 08:38 AM PST The Venus flytrap (Dionaea muscipula) is a carnivorous plant that encloses its prey using modified leaves as a trap. During this process, electrical signals known as action potentials trigger the closure of the leaf lobes. An interdisciplinary team of scientists has now shown that these electrical signals generate measurable magnetic fields. |
| How do electrons close to Earth reach almost the speed of light? Posted: 02 Feb 2021 08:37 AM PST In the Van Allen radiation belts, electrons can reach almost the speed of light. Researchers have revealed conditions for such strong accelerations. They had demonstrated in 2020: during solar storm plasma waves play a crucial role. However, it remained unclear why ultra-relativistic electron energies are not achieved in all solar storms. They now show: extreme depletions of the background plasma density are crucial. |
| Could playing host to hookworms help prevent aging? Posted: 02 Feb 2021 08:37 AM PST Parasitic worms could hold the key to living longer and free of chronic disease, according to a review article. |
| The secrets of 3000 galaxies laid bare Posted: 02 Feb 2021 05:54 AM PST The complex mechanics determining how galaxies spin, grow, cluster and die have been revealed following the release of all the data gathered during a massive seven-year astronomy research project. |
