| Robots sense human touch using camera and shadows Posted: 08 Feb 2021 02:30 PM PST Researchers have created a low-cost method for soft, deformable robots to detect a range of physical interactions, from pats to punches to hugs, without relying on touch at all. Instead, a USB camera located inside the robot captures the shadow movements of hand gestures on the robot's skin and classifies them with machine-learning software. |
| Posted: 08 Feb 2021 11:24 AM PST Researchers have developed the first 3D-printable 'bottlebrush' elastomer. The new material results in printed objects that have unusual softness and elasticity -- mechanical properties that closely resemble those of human tissue. |
| Rare blast's remains discovered in Milky Way's center Posted: 08 Feb 2021 08:43 AM PST Astronomers may have found our Galaxy's first example of an unusual kind of stellar explosion. This discovery adds to the understanding of how some stars shatter and seed the universe with elements critical for life on Earth. |
| Posted: 08 Feb 2021 08:42 AM PST Cells, like humans, cast votes to make decisions as a group. But how do they know what to vote for? Researchers have uncovered how cells actively seek information in order to make faster and better collective decisions to coordinate the growth of new blood vessels. This provides a new basis for understanding intelligence in cells. |
| Posted: 08 Feb 2021 08:42 AM PST By combining ferromagnets and two rotated layers of graphene, researchers open up a new platform for strongly interacting states using graphene's unique quantum degree of freedom. |
| Marmoset monkeys have personalities too Posted: 08 Feb 2021 07:46 AM PST In humans, differences in personalities have been evident since the ancient times. Personality in animals has long been ignored, but recently this question has received increasing research interest as it has been realized that personality has evolutionary and ecological significance. Behavioral biologists have now designed and used a set of tasks to assess personality of common marmosets. |
| Study of supergiant star Betelgeuse unveils the cause of its pulsations Posted: 08 Feb 2021 07:05 AM PST Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020, which has prompted speculation that Betelgeuse may be about to explode. |
| Scientists use trilayer graphene to observe more robust superconductivity Posted: 04 Feb 2021 11:32 AM PST Scientists report successfully stacking three sheets of graphene and then twisting each of them at a magic angle to produce a three-layered structure that is not only capable of superconductivity but does so more robustly and at higher temperatures than many of the double-stacked graphene. |
