With a hop, a skip and a jump, high-flying robot leaps through obstacles with ease Posted: 21 May 2019 01:24 PM PDT First unveiled in 2016, Salto the jumping robot stands at little less than a foot, but can vault over three times its height in a single bound. Now researchers have equipped the robot with a slew of new skills, giving it the ability to bounce in place like a pogo stick and jump through obstacle courses like an agility dog. Salto can even take short jaunts outside, powered by radio controller. |
Strain enables new applications of 2D materials Posted: 21 May 2019 01:24 PM PDT Superconductors' never-ending flow of electrical current could provide new options for energy storage and superefficient electrical transmission and generation. But the signature zero electrical resistance of superconductors is reached only below a certain critical temperature and is very expensive to achieve. Physicists believe they've found a way to manipulate superthin, waferlike monolayers of superconductors, thus changing the material's properties to create new artificial materials for future devices. |
Posted: 21 May 2019 09:46 AM PDT Chemists have synthesized the first ever functional non-native metal hydrogenase. |
Original kilogram replaced -- new International System of Units (SI) entered into force Posted: 21 May 2019 09:46 AM PDT In addition to other scientific units, the kilogram also is now defined by a natural constant. This is made possible by single crystals grown from highly enriched silicon-28. |
Predicting properties of composite materials Posted: 21 May 2019 09:45 AM PDT Can the properties of composite materials be predicted? Scientists have mastered this feat and thus can help achieve research objectives faster. This leads, for instance, to better recycling techniques and electrically conductive synthetic materials for the solar industry. |
New framework improves performance of deep neural networks Posted: 21 May 2019 09:45 AM PDT Researchers have developed a new framework for building deep neural networks via grammar-guided network generators. In experimental testing, the new networks -- called AOGNets -- have outperformed existing state-of-the-art frameworks, including the widely used ResNet and DenseNet systems, in visual recognition tasks. |
After GWAS studies, how to narrow the search for genes? Posted: 21 May 2019 09:40 AM PDT Genome-wide association studies (GWAS) often turn up a long list of genes that MIGHT help cause the trait of interest. Many algorithms can help scientists prioritize which genes to pursue further, but which one to choose? Borrowing from machine learning, and singling out one chromosome at a time, a new tool called Benchmarker helps scientists evaluate existing algorithms to guide their search for relevant genes. |
Cancer: Using 3D to test personalized treatments in five days Posted: 21 May 2019 07:29 AM PDT Researchers have devised a cell co-culture platform that reproduces a patient's tumor structure in 3D. The scientists can use it to test several drugs or their combinations at different stages of the tumor's development. They now need only five days to identify which treatment will be most effective for a particular case, and the combination can then be translated for clinical practice. |
Bring on faster Internet: Device packs more into optical fiber Posted: 21 May 2019 07:15 AM PDT A research team has developed a light beam device that could lead to faster Internet, clearer images of space and more detailed medical imaging. |
Water formation on the Moon demonstrated Posted: 21 May 2019 07:14 AM PDT A new study has shown chemical, physical, and material evidence for water formation on the Moon. |
Scientists use molecular tethers, chemical 'light sabers' for tissue engineering Posted: 21 May 2019 05:49 AM PDT Researchers have unveiled a new strategy to keep proteins intact and functional in synthetic biomaterials for tissue engineering. Their approach modifies proteins at a specific point so that they can be chemically tethered to the scaffold using light. Since the tether can also be cut by laser light, this method can create evolving patterns of signal proteins throughout a biomaterial scaffold to grow tissues made up of different types of cells. |
New robot can fly, creep and leap off buildings Posted: 20 May 2019 05:19 AM PDT Researchers have developed an experimental robot drone that flies like a typical quadcopter, drives on tough terrain and squeezes into tight spaces using the same motors. |
