| New observations of black hole devouring a star reveal rapid disk formation Posted: 26 Aug 2020 12:27 PM PDT When a star passes too close to a supermassive black hole, tidal forces tear it apart, producing a bright flare of radiation as material from the star falls into the black hole. Astronomers study the light from these 'tidal disruption events' (TDEs) for clues to the feeding behavior of the supermassive black holes lurking at the centers of galaxies, and new observations help resolve crucial details of this process. |
| Meteorite strikes may create unexpected form of silica Posted: 26 Aug 2020 12:13 PM PDT New research examining the crystal structure of the silica mineral quartz under shock compression is challenging longstanding assumptions about this ubiquitous material. |
| Key to fish family's land-walking abilities revealed in study of Asia's hillstream loaches Posted: 26 Aug 2020 10:18 AM PDT A new genetic and morphological study of South Asia's hillstream loach (Balitoridae) family is shedding new light on the fishes' unusual land-walking capabilities, including that of the family's strangest relative -- Cryptotora thamicola -- a rare, blind cavefish from Thailand with an uncanny ability to walk on land and climb waterfalls using four limbs that move in salamander-like fashion. |
| Cosmic rays may soon stymie quantum computing Posted: 26 Aug 2020 08:37 AM PDT Infinitesimally low levels of radiation, such as from incoming cosmic rays, may soon stymie progress in quantum computing. |
| Microscopic robots 'walk' thanks to laser tech Posted: 26 Aug 2020 08:37 AM PDT A collaboration has created the first microscopic robots that incorporate semiconductor components, allowing them to be controlled - and made to walk - with standard electronic signals. |
| Sleep duration, efficiency and structure change in space Posted: 26 Aug 2020 08:03 AM PDT It's hard to get a good night's sleep in space. An evaluation of astronauts serving on the Mir space station found that they experienced shorter sleep durations, more wakefulness, and changes in the structure of their sleep cycles while in microgravity. |
| How 'swapping bodies' with a friend changes our sense of self Posted: 26 Aug 2020 08:03 AM PDT A new study shows that, when pairs of friends swapped bodies in a perceptual illusion, their beliefs about their own personalities became more similar to their beliefs about their friends' personalities. The findings suggest that this tie between our psychological and physical sense of self is involved in memory function: when our mental self-concept doesn't match our physical self, our memory can become impaired. |
| Scientists use fruit peel to turn old batteries into new Posted: 26 Aug 2020 07:16 AM PDT Scientists have developed a novel method of using fruit peel waste to extract and reuse precious metals from spent lithium-ion batteries in order to create new batteries. The scientists say that their waste-to-resource approach tackles both food waste and electronics waste, supporting the development of a circular economy with zero waste. |
