| New algorithm could help enable next-generation deep brain stimulation devices Posted: 01 Jun 2021 01:50 PM PDT Researchers have developed a technique that could allow deep brain stimulation devices to sense activity in the brain and adjust stimulation accordingly. |
| Prototype of robotic device to pick, trim button mushrooms Posted: 01 Jun 2021 01:50 PM PDT Researchers have developed a robotic mechanism for mushroom picking and trimming and demonstrated its effectiveness for the automated harvesting of button mushrooms. |
| Innovative surgical simulator is a significant advance in training trauma teams Posted: 01 Jun 2021 01:50 PM PDT Simulators have long been used for training surgeons and surgical teams, but traditional simulator platforms typically have a built-in limitation: they often simulate one or a limited number of conditions that require performance of isolated tasks, such as placing an intravenous catheter, instead of simulating and providing opportunities for feedback on the performance of multiple interventions that a trauma victim may require at the same time. To overcome this limitation, the Advanced Modular Manikin (AMM), an innovative simulation platform that allows integration of other simulation devices, was developed and field testing was conducted, with support from the Department of Defense (DoD). |
| New method to improve durability of nano-electronic components, further semiconductor manufacturing Posted: 01 Jun 2021 01:50 PM PDT Researchers have developed a novel approach to mitigating electromigration in nanoscale electronic interconnects that are ubiquitous in state-of-the-art integrated circuits. This was achieved by coating copper metal interconnects with hexagonal boron nitride (hBN), an atomically-thin insulating two-dimensional (2D) material that shares a similar structure as the 'wonder material' graphene. |
| Engineers demonstrate a quantum advantage Posted: 01 Jun 2021 12:56 PM PDT Researchers experimentally show that quantum resources have an advantage over classical -- even in the NISQ era. |
| 'Self-aware' materials build the foundation for living structures Posted: 01 Jun 2021 12:20 PM PDT New research describes a new metamaterial system that acts as its own sensor, recording and relaying important information about the pressure and stresses on its structure. The so-called 'self-aware metamaterial' generates its own power and can be used for a wide array of sensing and monitoring applications. |
| Harmonious electronic structure leads to enhanced quantum materials Posted: 01 Jun 2021 12:19 PM PDT Researchers have discovered a new mechanism in magnetic compounds that couples multiple topological bands. The coupling can significantly enhance the effects of quantum phenomena. |
| How AI could alert firefighters of imminent danger Posted: 01 Jun 2021 10:58 AM PDT Researchers have developed an artificial-intelligence-powered tool to predict and warn of a deadly phenomenon in burning buildings known as flashover, when flammable materials in a room ignite almost simultaneously, producing a potentially ferocious blaze. The tool's predictions are based on temperature data from a building's heat detectors, and, remarkably, it is designed to operate even after heat detectors begin to fail, making do with the remaining devices. |
| A new direction of topological research is ready for take off Posted: 01 Jun 2021 10:58 AM PDT Through a recently developed experimental platform, topological matter can be realized in a fast, cost efficient, and versatile way. A breakthrough has now been achieved by physicists as they have observed topological phenomena in a circuit system with gain and loss. The theoretical foundation for non-Hermitian topology might enable optronic technologies in the long run. |
| Scientists demonstrate a better, more eco-friendly method to produce hydrogen peroxide Posted: 01 Jun 2021 10:57 AM PDT Hydrogen peroxide (H2O2) is used to disinfect minor cuts at home and for oxidative reactions in industrial manufacturing. The pandemic has further fueled demand for its antiseptic properties, but H2O2 is actually difficult and expensive to manufacture at scale. A team led by the University of Illinois Urbana-Champaign has demonstrated a more efficient and environmentally friendly method to produce H2O2, according to a recent study published in the Journal of the American Chemical Society. |
| Researchers fine-tune control over AI image generation Posted: 01 Jun 2021 10:57 AM PDT Researchers have developed a new state-of-the-art method for controlling how artificial intelligence (AI) systems create images. The work has applications for fields from autonomous robotics to AI training. |
| How news coverage affects public trust in science Posted: 01 Jun 2021 10:57 AM PDT News media reports about scientific failures that do not recognize the self-correcting nature of science can damage public perceptions of trust and confidence in scientific work, according to new findings. |
| Mass of human chromosomes measured Posted: 01 Jun 2021 10:57 AM PDT Researchers used a powerful X-ray beam to determine the number of electrons in a spread of 46 chromosomes which they used to calculate mass. |
| Why deep freezing iron-based materials makes them both magnetic and superconducting Posted: 01 Jun 2021 10:57 AM PDT Physicists have uncovered a new mechanism for enabling magnetism and superconductivity to co-exist in the same material. |
| Turbulence in interstellar gas clouds reveals multi-fractal structures Posted: 01 Jun 2021 10:57 AM PDT Astronomers describe the complex structure of the interstellar medium using a new mathematical method. The dispersion of interstellar turbulence in gas clouds before star formation unfolds in a cosmically small space. |
| Californian smoke drifted as far as Europe in 2020 and caused heavy clouding of sun Posted: 01 Jun 2021 09:18 AM PDT The smoke from the extreme forest fires on the US West Coast in September 2020 travelled over many thousands of kilometers to Central Europe, where it continued to affect the atmosphere for days afterwards. A comparison of ground and satellite measurements now shows: The forest fire aerosol disturbed the free troposphere over Leipzig in Germany as never before. |
| 'Electronic nose' accurately sniffs out hard-to-detect cancers Posted: 01 Jun 2021 09:17 AM PDT An odor-based test that sniffs out vapors emanating from blood samples was able to distinguish between benign and pancreatic and ovarian cancer cells with up to 95% accuracy. |
| Light-shrinking material lets ordinary microscope see in super resolution Posted: 01 Jun 2021 07:07 AM PDT Engineers have developed a technology that turns a conventional light microscope into what's called a super-resolution microscope. It improves the microscope's resolution (from 200 nm to 40 nm) so that it can be used to directly observe finer structures and details in living cells. |
| The secret to stickiness of mussels underwater Posted: 01 Jun 2021 07:06 AM PDT Mussels survive by sticking to rocks in the fierce waves or tides underwater. Materials mimicking this underwater adhesion are widely used for skin or bone adhesion, for modifying the surface of a scaffold, or even in drug or cell delivery systems. However, these materials have not entirely imitated the capabilities of mussels. |
| Greenhouse gas emissions from reservoirs higher than previously expected Posted: 01 Jun 2021 07:06 AM PDT A new study shows per-area greenhouse gas emissions from the world's water reservoirs are around 29% higher than suggested by previous studies, but that practical measures could be taken to help reduce that impact. |
