| BirdBot is energy-efficient thanks to nature as a model Posted: 16 Mar 2022 11:57 AM PDT A team of scientists has constructed a robot leg that, like its natural model, is very energy efficient. BirdBot benefits from a foot-leg coupling through a network of muscles and tendons that extends across multiple joints. In this way, BirdBot needs fewer motors than previous legged robots and could, theoretically, scale to large size. |
| What's the prevailing opinion on social media? Look at the flocks, says researcher Posted: 16 Mar 2022 10:26 AM PDT A communication researcher has developed a framework for measuring the slippery concept of social media public opinion. Murmuration identifies meaningful groups of social media actors based on the 'who-follows-whom' relationship. The actors attract like-minded followers to form 'flocks,' which serve as the units of analysis. As opinions form and shift in response to external events, the flocks' unfolding opinions move like the fluid murmuration of airborne starlings. |
| Pivotal technique harnesses cutting-edge AI capabilities to model and map the natural environment Posted: 16 Mar 2022 10:26 AM PDT Scientists have developed a pioneering new technique that harnesses the cutting-edge capabilities of AI to model and map the natural environment in intricate detail. |
| Tiny battery-free devices float in the wind like dandelion seeds Posted: 16 Mar 2022 09:08 AM PDT Inspired by how dandelions use the wind to distribute their seeds, a team has developed a tiny sensor-carrying device that can be blown by the wind as it tumbles toward the ground. |
| Toward a quantum computer that calculates molecular energy Posted: 16 Mar 2022 09:08 AM PDT Researchers have developed an algorithm that uses the most quantum bits to date to calculate ground state energy, the lowest-energy state in a quantum mechanical system. The discovery could make it easier to design new materials. |
| AI to predict antidepressant outcomes in youth Posted: 16 Mar 2022 08:50 AM PDT Researchers have taken the first step in using artificial intelligence (AI) to predict early outcomes with antidepressants in children and adolescents with major depressive disorder. |
| Nuclear reactor power levels can be monitored using seismic and acoustic data Posted: 16 Mar 2022 08:50 AM PDT Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study. |
| Intensity control of projectors in parallel: A doorway to an augmented reality future Posted: 16 Mar 2022 06:17 AM PDT A challenge to adopting augmented reality (AR) in wider applications is working with dynamic objects, owing to a delay between their movement and the projection of light onto their new position. But, scientists may have a workaround. They have developed a method that uses multiple projectors while reducing delay time. Their method could open the door to a future driven by AR, helping us live increasingly technology-centered lives. |
| Stackable 'holobricks' can make giant 3D images Posted: 15 Mar 2022 04:36 PM PDT Researchers have developed a new method to display highly realistic holographic images using 'holobricks' that can be stacked together to generate large-scale holograms. |
