| 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. |
| Too dry, too hot, or too wet: Increasing weather persistence in European summer Posted: 06 Dec 2021 08:30 AM PST Global warming makes long lasting weather situations in the Northern hemisphere's summer months more likely -- which in turn leads to more extreme weather events, a novel analysis of atmospheric images and data finds. These events include heatwaves, droughts, intense rainy periods. Especially in Europe, but also in Russia, persistent weather patterns have increased in number and intensity over the last decades with weather extremes occurring simultaneously at different locations. |
| 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. |
| Long-range four-stranded DNA structures found to play a role in rare aging disease Posted: 06 Dec 2021 08:30 AM PST A special form of four-stranded DNA, recently seen in human cells, has been found to interact with a gene that causes Cockayne Syndrome when faulty. |
| 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. |
| Male spiders are attracted by a female like planets orbiting a star Posted: 06 Dec 2021 08:30 AM PST The tiny male golden orb-weaving spider faces a considerable challenge when searching for a mate. He is a fraction of the size of the massive female, but must carefully enter her web and approach her without being noticed, because the cannibalistic female will kill and eat him if he makes one wrong move on her web. Add to this gamble the competition he faces from other males also on the delicate arena of the web, and you have a complex optimization problem that even human analysts would find daunting. Yet these little spiders barely have what we would recognize as a brain. How then do they manage? |
| Minimal effort required: A ten-minute run can boost brain processing Posted: 06 Dec 2021 08:30 AM PST Researchers found that as little as ten minutes of moderate-intensity running could benefit mental health. In study participants, both mood and cognitive functions improved, and the activation of bilateral prefrontal subregions associated with cognitive function and mood also increased. These results demonstrate the potential advantages of exercise prescriptions for various conditions including mental health treatment. |
| The sunshine vitamin that ‘D’elivers on cardio health Posted: 06 Dec 2021 08:30 AM PST Free from the sun, vitamin D delivers a natural source for one of the hormones essential to our bodies, especially the bones. But when you're down on this essential nutrient, it's not only your bones that could suffer, but also your cardio health, according to new research. |
| 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. |
| Diagnosis from the sky: Catching insect infestations within forests before it’s too late Posted: 06 Dec 2021 08:30 AM PST Researchers are working to improve remote sensing technology's ability to detect subtle changes in real-time across the landscape, namely to diagnose insect infestations in forests before irreparable damage is done. |
| Glucose control is a key factor for reduced cancer risk in obesity and type 2 diabetes Posted: 06 Dec 2021 08:30 AM PST Good glucose control is important for reduction of cancer risk in obesity and type 2 diabetes. Large durable weight loss, as such, appears to afford protection against cancer, but with good glucose control the number of cancer cases also drops radically, a new study shows. |
| Migratory birds have lighter-colored feathers Posted: 06 Dec 2021 08:30 AM PST Migratory birds are specially adapted to find their way over extreme distances that represent remarkable tests of endurance. Now, researchers have discovered an unexpected way that migratory birds keep their cool during such arduous journeys: lighter-colored feathers. |
| Cataract surgery linked with lessened dementia risk Posted: 06 Dec 2021 08:30 AM PST Based on the longitudinal data of over 3,000 study participants, researchers found that subjects who underwent cataract surgery had nearly 30% lower risk of developing dementia from any cause compared with those who did not. This lowered risk persisted for at least a decade after surgery. Cataract surgery was also associated with lower risk of Alzheimer disease dementia specifically. |
| Discovering new drugs with help from Darwinian principles Posted: 06 Dec 2021 08:29 AM PST Our body must constantly defend itself against bacteria and viruses. It generates millions of different antibodies, which are selected to recognise the enemy and trigger the best possible immune response. Scientists use these antibodies to for therapeutic purposes to target proteins and disrupt their harmful. However, identifying the small molecules that will form the basis of the drug is a long and tedious process. Chemists have now developed a technique inspired by the theory of Darwinian evolution: amplifying the best combinations and generating diversity allows biology to find solutions to new problems. |
| 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. |
