Researchers probed Martian meteorites to reconstruct Mars’ chaotic history. Their findings suggest that Mars might not have had a global magma ocean. Barnes is an assistant professor of planetary sciences in the University of Arizona Lunar and Planetary Laboratory. She and her team chemically analyzed the Black Beauty meteorite and the infamous Allan Hills 84001…

Researchers have developed a method to change a cellular material’s fundamental topology at the microscale. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a method to change a cellular material’s fundamental topology at the microscale. The research is published in Nature. «Creating cellular structures capable of…

Researchers have discovered a uniquely quantum effect in erasing information that may have significant implications for the design of quantum computing chips. Their surprising discovery brings back to life the paradoxical ‘Maxwell’s demo’, which has tormented physicists for over 150 years. The thermodynamics of computation was brought to the fore in 1961 when Rolf Landauer,…

Fake audio or video content has been ranked by experts as the most worrying use of artificial intelligence in terms of its potential applications for crime or terrorism, according to a new report. The study, published in Crime Science and funded by the Dawes Centre for Future Crime at UCL (and available as a policy…

Scientists have measured the masses of the giant planets of the V1298 Tau system, just 20 million year old. Masses for such young giant planets had not been obtained previously, and this is the first evidence that these objects have already reached their final size at very early stages of their evolution. The study, led…

Data collected by the Arecibo Radio Telescope before it collapsed late last year will help astronomers better understand how our local neighbourhood of galaxies formed. Arecibo was the world’s largest single-dish radio telescope until it was surpassed in 2016 by China’s Five-hundred-meter Aperture Spherical Telescope (FAST). At the end of 2020, Arecibo’s 900-ton receiver platform…

New supercomputer simulations show that after creating a ring, a planet can move away and leave the ring behind. Not only does this bolster the planet theory for ring formation, the simulations show that a migrating planet can produce a variety of patterns matching those actually observed in disks. Young stars are encircled by protoplanetary…

The James Webb Space Telescope team has fully deployed the spacecraft’s 70-foot sunshield, a key milestone in preparing it for science operations. The sunshield — about the size of a tennis court at full size — was folded to fit inside the payload area of an Arianespace Ariane 5 rocket’s nose cone prior to launch.…

NASA’s James Webb Space Telescope launched Dec. 25 from Europe’s Spaceport in French Guiana, South America. The Webb observatory’s mission is to seek the light from the first galaxies in the early universe and to explore our own solar system, as well as planets orbiting other stars, called exoplanets. A joint effort with ESA (European…

Astronomers have obtained the deepest and sharpest images to date of the region around the supermassive black hole at the center of our galaxy. The new images zoom in 20 times more than what was possible before the VLTI and have helped astronomers find a never-before-seen star close to the black hole. By tracking the…
