| Cosmic particle accelerator at its limit Posted: 10 Mar 2022 11:37 AM PST With the help of special telescopes, researchers have observed a cosmic particle accelerator as never before. Observations made with the gamma ray observatory H.E.S.S. in Namibia show for the first time the course of an acceleration process in a stellar process called a nova, which comprises powerful eruptions on the surface of a white dwarf. A nova creates a shock wave that tears through the surrounding medium, pulling particles with it and accelerating them to extreme energies. Surprisingly, the nova 'RS Ophiuchi' seems to cause particles to accelerate at speeds reaching the theoretical limit, corresponding to ideal conditions. |

| Video game-based therapy helps stroke patients Posted: 09 Mar 2022 01:55 PM PST After a stroke, patients may lose feeling in an arm or experience weakness and reduced movement that limits their ability to complete basic daily activities. Traditional rehabilitation therapy is very intensive, time-consuming and can be both expensive and inconvenient, especially for rural patients travelling long distances to in-person therapy appointments. That's why a team of researchers utilized a motion-sensor video game, Recovery Rapids, to allow patients recovering from a stroke to improve their motor skills and affected arm movements at home while checking in periodically with a therapist via telehealth. |

| Introducing organs-on-chips to the lymph system Posted: 09 Mar 2022 12:17 PM PST Currently, there is little research focused on understanding mechanisms and drug discovery of lymphatic vascular diseases. However, conditions such as lymphedema, a buildup of fluid in the body when the lymph system is damaged, impact more than 200,000 people every year in the United States alone. |
| 196 lasers help scientists recreate the conditions inside gigantic galaxy clusters Posted: 09 Mar 2022 11:09 AM PST Scientists have long known that the hydrogen gas in galaxy clusters is searingly hot -- about 10 million degrees Kelvin, or roughly the same temperature as the center of the sun -- which is so hot that hydrogen atoms cannot exist. Instead the gas is a plasma consisting of protons and electrons. But a puzzle persists: There is no straightforward explanation for why or how the gas stays so hot. According to the normal rules of physics, it should have cooled within the age of the universe. But it hasn't. Scientists have created conditions similar to the hot gas in gigantic galaxy clusters. |
| Black hole billiards in the centers of galaxies Posted: 09 Mar 2022 10:19 AM PST Researchers provide the first plausible explanation to why one of the most massive black hole pairs observed to date by gravitational waves also seemed to merge on a non-circular orbit. Their suggested solution involves a chaotic triple drama inside a giant disk of gas around a super massive black hole in a galaxy far, far away. |
| Scientists capture the fleeting dance of moiré excitons Posted: 09 Mar 2022 10:19 AM PST Scientists have visualized the two parts of an elusive particle -- the moiré exciton -- to reveal its structure and unique properties. |
| New technology enables unprecedented glimpse inside single brain cells Posted: 09 Mar 2022 10:18 AM PST Researchers have developed a new genomic technology to simultaneously analyze the DNA, RNA and chromatin -- a combination of DNA and protein -- from a single cell. The method, which took five years to develop, is an important step forward for large collaborations where multiple teams are working simultaneously to classify thousands of new cell types. The new technology will help streamline analyses. |
| Avian secret: The key to agile bird flight is switching quickly between stable and unstable gliding Posted: 09 Mar 2022 08:11 AM PST While it had been assumed that unstable gliding was the key to agility in bird flight, a collaboration between aerospace engineers and biologists has revealed that stability plays a role. |

Based on novel, quantum nanoribbons terminating on 'zigzag' edges, such devices would switch from non-conducting to conducting state, whereby electrical current could flow along topological edge states without wasted dissipation of energy. |
| New research sheds light on nature of friction in multi-layered graphene Posted: 09 Mar 2022 07:44 AM PST Multi-layered graphene is a promising carbon-based nanomaterial for a variety of next-generation technologies, but the relationships between its surface structures and properties are not entirely clear.
