| Going gentle on mechanical quantum systems Posted: 13 May 2022 10:49 AM PDT Systems in which mechanical motion is controlled at the level of individual quanta are emerging as a promising quantum-?technology platform. New experimental work now establishes how quantum properties of such systems can be measured without destroying the quantum state -- a key ingredient for tapping the full potential of mechanical quantum systems. |
| Malaria parasites form vortices Posted: 13 May 2022 10:48 AM PDT Researchers managed to set larger groups of malaria parasites into motion and to analyze the acquired image data. The collectively moving pathogens form vortex systems that are largely determined by physical principles. Computer simulations helped identify the mechanisms underlying these rotating movements. |
| Remote sensing research improves hurricane response Posted: 13 May 2022 10:48 AM PDT Researchers are investigating better ways to predict where road-clogging debris will be most severe after tropical cyclones. |
| Dragonflies use vision, subtle wing control to straighten up and fly right Posted: 13 May 2022 08:32 AM PDT Researchers have untangled the intricate physics and neural controls that enable dragonflies to right themselves while they're falling. |
| New study indicates limited water circulation late in the history of Mars Posted: 13 May 2022 07:34 AM PDT A research team has investigated a meteorite from Mars using neutron and X-ray tomography. The technology, which will probably be used when NASA examines samples from the Red Planet in 2030, showed that the meteorite had limited exposure to water, thus making life at that specific time and place unlikely. |
| When quantum particles fly like bees Posted: 12 May 2022 11:43 AM PDT A quantum system with only 51 charged atoms can take on more than two quadrillion different states. Calculating the system's behavior is child's play for a quantum simulator. But verifying the result is almost impossible, even with today's supercomputers. A research team has now shown how these systems can be verified using equations formulated in the 18th century. |
| Researchers develop wireless implantable vascular monitoring system Posted: 12 May 2022 09:19 AM PDT Researchers are improving the odds for patients with the development of an implantable soft electronic vascular monitoring system. Their smart stent and printed soft sensors, is capable of wireless real-time monitoring of hemodynamics without batteries or circuits. |
| The deadly impact of urban streets that look like highways Posted: 12 May 2022 09:19 AM PDT Serious auto crashes in urban areas are more likely on city streets that look to drivers like highways, new research suggests. The study used a novel approach: researchers applied machine learning techniques to analyze more than 240,000 images of road segments in Columbus, Ohio. |
| Study finds realism a key factor in driving engagement with virtual reality videos Posted: 12 May 2022 09:19 AM PDT A recent study finds that realism is a key factor in determining whether viewers engage with virtual reality videos -- and that engagement is itself a key factor in determining whether viewers are interested in watching VR videos in the future. |
| Aerodynamic model of a moving car and its tires Posted: 12 May 2022 09:18 AM PDT Engineers have produced a video simulation to illustrate the complex aerodynamics around a moving car and its tires. |
| Video games can help boost children's intelligence Posted: 12 May 2022 09:18 AM PDT Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect. |
| Towards more efficient, non-toxic, and flexible thin-film solar cells Posted: 12 May 2022 06:27 AM PDT While solar cells are a great alternative to fossil fuels, the environmental impact of the processes involved in manufacturing solar cells has been a concern. Solar panel fabrication often involves toxic materials such as cadmium and industrial waste. In a new study, researchers have now developed an eco-friendly method that eliminates the use of toxic cadmium in the production process to produce cost-effective, efficient, and eco-friendly solar cells. |
| A nontoxic glue for plywood -- from glucose, citric acid Posted: 11 May 2022 05:57 AM PDT The go-to materials for building home furniture, décor and floors are composite wood products that come in large sheets. But the glues and resins holding together particleboard, fiberboard and plywood usually contain formaldehyde and could release this probable carcinogen into the air. To develop a nontoxic adhesive, researchers have combined glucose and citric acid -- sugar and an orange juice ingredient -- into a strong, water-resistant wood glue for plywood. |
