| New type of earthquake discovered Posted: 06 Dec 2021 08:31 AM PST A research team has documented a new type of earthquake in an injection environment in British Columbia, Canada. The seismic events are slower than conventional earthquakes. Their existence supports a scientific theory that until now had not been sufficiently substantiated by measurements. |
| Researchers crack the synthetic code of rare molecules sought after in drug development Posted: 06 Dec 2021 08:30 AM PST A research team has succeeded in producing two molecules that are otherwise only formed by microorganisms from extremely contaminated wastewater in an abandoned mine in South Korea. The method, which took four years to develop, could pave the way for new types of drugs. |
| Liquid crystals for fast switching devices Posted: 06 Dec 2021 08:30 AM PST An international team has investigated a newly synthesized liquid-crystalline material that promises applications in optoelectronics. Simple rod-shaped molecules with a single center of chirality self-assemble into helical structures at room temperature. Using soft X-ray resonant scattering at BESSY II, the scientists have now been able to determine the pitch of the helical structure with high precision. Their results indicate an extremely short pitch at only about 100 nanometres which would enable applications with particularly fast switching processes. |
| Spaceflight wreaks havoc on liver metabolism Posted: 06 Dec 2021 08:30 AM PST Researchers have demonstrated that microgravity and other environmental factors in space play different roles in inducing oxidative stress, which, in turn, alters the metabolism of sulfur-containing compounds in the liver of mice. The study highlighted steps that can be taken, such as boosting antioxidant capacity with dietary supplements, to safeguard astronaut health. |
| Teaching an old chemical new tricks Posted: 06 Dec 2021 08:29 AM PST Chemists have put a new spin on an old catalyst called 'Barton's base' to invent a faster, 'greener' chemical reaction. Their new chemistry speeds up molecule synthesis used for discovering new materials and drugs. |
| X-ray laser reveals how radiation damage arises Posted: 06 Dec 2021 06:06 AM PST An international research team has used the X-ray laser European XFEL to gain new insights into how radiation damage occurs in biological tissue. The study reveals in detail how water molecules are broken apart by high-energy radiation, creating potentially hazardous radicals and electrically charged ions, which can go on to trigger harmful reactions in the organism. |
| Chemical pollutants disrupt reproduction in anemonefish Posted: 05 Dec 2021 08:17 AM PST Ocean pollution is unfortunately becoming more commonplace, raising concerns over the effect of chemicals that are leaching into the water. In a new study, researchers have discovered how these chemicals can affect the reproduction in common anemonefish Amphiprion ocellaris. |
| Breakthrough in understanding cosmic forces that shape Earth's heliosphere Posted: 03 Dec 2021 12:14 PM PST Astrophysicists have made a breakthrough discovery in our understanding of the cosmic forces that shape the heliosphere. |
| Printing technique creates effective skin equivalent, heals wounds Posted: 03 Dec 2021 10:12 AM PST Researchers have developed an approach to print skin equivalents, which may play a future role in facilitating the healing of chronic wounds. They used suspended layer additive manufacturing, creating a gel-like material to support the skin equivalent that can then support a second phase of gel injection. During printing, the skin layers are deposited within the support gel. After printing, the team washed away the support material, leaving behind the layered skin equivalent. |
| Predicting protein-protein interactions Posted: 02 Dec 2021 11:15 AM PST Scientists have collaborated to build a structurally-motivated deep learning method built from recent advances in neural language modeling. The team's deep-learning model, called D-SCRIPT, was able to predict protein-protein interactions (PPIs) from primary amino acid sequences. |
| Giant planets could reach 'maturity' much earlier than previously thought, study reveals Posted: 02 Dec 2021 09:30 AM PST Scientists have measured the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is the first evidence that these objects have already reached their final size at very early stages of their evolution. |
| COVID-19 mobile robot could detect and tackle social distancing breaches Posted: 01 Dec 2021 11:53 AM PST A new strategy to reduce the spread of COVID-19 employs a mobile robot that detects people in crowds who are not observing social-distancing rules, navigates to them, and encourages them to move apart. |
