| Physicists discover novel quantum effect in bilayer graphene Posted: 04 Nov 2021 01:26 PM PDT Theorists have observed a rare phenomenon called the quantum anomalous Hall effect in a very simple material. Previous experiments have detected it only in complex or delicate materials. |
| Study finds fish rubbing up against their predators — sharks Posted: 04 Nov 2021 01:26 PM PDT While rubbing up against a shark sounds like a risky move if you're a fish, a collaborative research team found that this behavior is frequent, widespread, and could play a previously unappreciated important ecological role for aquatic animals. |
| Female finches are picky but pragmatic when choosing a mate Posted: 04 Nov 2021 11:08 AM PDT Female zebra finches are choosy but flexible when it comes to finding a mate, allowing them to avoid the fitness costs of being too selective when competition for males is high, researchers report. |
| Jet from giant galaxy M87: Computer modelling explains black hole observations Posted: 04 Nov 2021 11:01 AM PDT An enormous jet of particles emitted by the giant galaxy M87 can be observed astronomically in various wavelengths. Scientists have developed a theoretical model of the morphology of this jet using complex supercomputer calculations. The images from these calculations provide an unprecedented match with astronomical observations and confirm Einstein's theory of general relativity. |
| Astronomers make most distant detection yet of fluorine in star-forming galaxy Posted: 04 Nov 2021 09:13 AM PDT A new discovery is shedding light on how fluorine -- an element found in our bones and teeth as fluoride -- is forged in the Universe. Astronomers have detected this element in a galaxy that is so far away its light has taken over 12 billion years to reach us. This is the first time fluorine has been spotted in such a distant star-forming galaxy. |
| Healable carbon fiber composite offers path to long-lasting, sustainable materials Posted: 04 Nov 2021 08:53 AM PDT Researchers have created a new type of carbon fiber reinforced material that is as strong and light as traditionally used materials, but can be repeatedly healed with heat, reversing any fatigue damage. This also provides a way to break it down and recycle it when it reaches the end of its life. |
| Likely home of Martian meteorites pinpointed Posted: 04 Nov 2021 08:53 AM PDT Researchers have pinpointed the likely origin of a group of meteorites ejected from Mars, using a machine learning algorithm that analyses high-resolution planetary images. |
| Making aircraft fuel from sunlight and air Posted: 04 Nov 2021 08:52 AM PDT Scientists have built a plant that can produce carbon-neutral liquid fuels from sunlight and air. The next goal will be to take this technology to industrial scale and achieve competitiveness. Researchers now describe how this novel solar reactor functions and outline a policy framework that would provide incentives to expand the production of 'solar kerosene'. |
