| Engineered defects in crystalline material boosts electrical performance Posted: 27 May 2021 12:53 PM PDT Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance. |
| Technology predicts protein stability Posted: 27 May 2021 12:02 PM PDT A digital tool that will make it cheaper, safer and faster to develop new medicines is being rolled out by scientists. |
| Posted: 27 May 2021 11:52 AM PDT Long interested in interactions between robots and humans, researchers have created EVA, a new autonomous robot with a soft and expressive face that responds to match the expressions of nearby humans. |
| Lead levels in urban soil are declining but hotspots persist Posted: 27 May 2021 08:26 AM PDT Lead paint and leaded gasoline have been banned for decades, but unsafe levels of lead remain in some urban soils, a new study finds. The researchers mapped soil lead concentrations along 25 miles of streets in Durham, N.C. Though contamination generally has declined since the 1970s, soil collected near houses predating 1978 still averaged 649 milligrams of lead per kilogram of soil, well above the 400 mg/kg threshold associated with health risks to children. |
| New microscopy method reaches deeper into the living brain Posted: 27 May 2021 08:25 AM PDT Researchers have developed a new technique that allows microscopic fluorescence imaging at four times the depth limit imposed by light diffusion. Fluorescence microscopy is often used to image molecular and cellular details of the brain in animal models of various diseases but, until now, has been limited to small volumes and highly invasive procedures due to intense light scattering by the skin and skull. |
| How metals work together to weaken hardy nitrogen-nitrogen bonds Posted: 27 May 2021 08:25 AM PDT Chemists have determined the structure of the complex that forms when N2 binds to an iron-sulfur cluster, offering clues as to how microbes use nitrogenase enzymes to convert atmospheric dinitrogen into ammonia. |
| Shiny mega-crystals that build themselves Posted: 27 May 2021 08:25 AM PDT Researchers are playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. Although these nano 'Lego bricks' interact with each other with forces vastly different and much weaker than those holding atoms and ions together, they form crystals all by themselves, the structures of which resemble the ones of natural minerals. These superlattices exhibit unique properties such as superfluorescence - and may well usher in a new era in materials science. |
| Controlling magnetization by surface acoustic waves Posted: 27 May 2021 08:25 AM PDT Using the circular vibration of surface acoustic waves, a collaborative research group have successfully controlled the magnetization of a ferromagnetic thin film. |
| Fisheries resilience following Tohoku tsunami Posted: 27 May 2021 08:25 AM PDT A small Japanese fishing community devastated by the Great East Japan Earthquake and Tsunami of 2011 managed to recover from the disaster through cooperative community activity despite the propensity for individualist-competitive behavior within fisheries - cooperative activity that continued many years later. |
| Mathematical model developed to prevent botulism Posted: 27 May 2021 08:24 AM PDT Food producers can use a mathematical model to ensure their products do not cause botulism. |
| It takes some heat to form ice Posted: 27 May 2021 08:24 AM PDT Researchers tracked down the first step in ice formation at a surface, revealing that additional energy is needed for water before ice can start to form. |
| Improving computer vision for AI Posted: 27 May 2021 06:14 AM PDT Researchers have developed a new method that improves how artificial intelligence learns to see. |
| Banning the sale of fossil-fuel cars benefits the climate when replaced by electric cars Posted: 27 May 2021 05:43 AM PDT If a ban were introduced on the sale of new petrol and diesel cars, and they were replaced by electric cars, the result would be a great reduction in carbon dioxide emissions. That is the finding of new research, looking at emissions from the entire life cycle - from manufacture of electric cars and batteries, to electricity used for operation. |
| The path to more human-like robot object manipulation skills Posted: 26 May 2021 12:02 PM PDT Scientists summarize, compare and contrast research in learned robot manipulation through the lens of adaptability and outline promising research directions for the future. |
