| Molecular robots work cooperatively in swarms Posted: 20 Apr 2022 12:14 PM PDT Scientists have demonstrated that molecular robots are able to accomplish cargo delivery by employing a strategy of swarming, achieving a transport efficiency five times greater than that of single robots. |
| Clearing up biases in artificial intelligence Posted: 20 Apr 2022 10:36 AM PDT Scientists have noticed grave disparities in artificial intelligence, noting that the methods are not objective, especially when it comes to geodiversity. AI tools, whether forecasting hail, wind or tornadoes, are assumed to be inherently objective, says one of the researchers. They aren't, she says. |
| Lasers trigger magnetism in atomically thin quantum materials Posted: 20 Apr 2022 10:36 AM PDT Researchers have discovered that light -- from a laser -- can trigger a form of magnetism in a normally nonmagnetic material. This magnetism centers on the behavior of electrons 'spins,' which have a potential applications in quantum computing. Scientists discovered that electrons within the material became oriented in the same direction when illuminated by photons from a laser. By controlling and aligning electron spins at this level of detail and accuracy, this platform could have applications in the field of quantum simulation. |
| Fewer smartphones, more well-being Posted: 20 Apr 2022 10:35 AM PDT How much digital detox is necessary to live a better life? The good news is that we don't have to waive them completely. |
| 'Dative epitaxy': A new way to stack crystal films Posted: 20 Apr 2022 09:20 AM PDT Scientists have grown thin films of two different crystalline materials on top of each other using an innovative technique called 'dative epitaxy.' The researchers discovered the method by surprise. As a physicist explains, dative epitaxy holds layers of different materials together via a weak attractive force between the materials, paired with occasional chemical bonds called 'dative bonds.' |
