Phys.org / Antiferromagnetic metal exhibits diode-like behavior without external magnetic field
Antiferromagnetic (AF) materials are made up of atoms or molecules with atomic spins that align in antiparallel directions of their neighbors. The magnetism of each individual atom or molecule is canceled out by the one next ...
Phys.org / Whale hunting began 5,000 years ago in South America, a millennium earlier than previously thought
The hunting of large whales goes back much further in time than previously thought. New research from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB) and the Department ...
Phys.org / Replication efforts suggest 'smoking gun' evidence isn't enough to prove quantum computing claims
A group of scientists, including Sergey Frolov, professor of physics at the University of Pittsburgh, and co-authors from Minnesota and Grenoble have undertaken several replication studies centered around topological effects ...
Phys.org / X-ray spectra provide sharpest image to date of a rapidly spinning black hole
The X-Ray Imaging and Spectroscopy Mission (XRISM), a joint mission between the Japanese Aerospace Exploration Agency (JAXA) and NASA, launched on Sept. 7th, 2023. Its advanced imaging filters and spectrometers were designed ...
Phys.org / Reviving antibiotics with two-faced nanoparticles
Over the decades, many strains of disease-causing bacteria have evolved defenses to even the most potent antibiotics, setting off a growing health crisis. The rise of antibiotic-resistant "superbugs" has also set off an arms ...
Phys.org / Astronomers build molecular cloud atlas for nearby Andromeda galaxy
Astronomers from Cardiff University, UK, have employed the Combined Array for Research in Millimeter-wave Astronomy (CARMA) to explore the nearby Andromeda galaxy. Results of the observational campaign, published December ...
Medical Xpress / COVID-19 still claims more than 100,000 US lives each year
Centers for Disease Control and Prevention researchers report national estimates of 43.6 million COVID-19-associated illnesses and 101,300 deaths in the US during October 2022 to September 2023, plus 33.0 million illnesses ...
Phys.org / How a biological version of rock-paper-scissors determines if lizard colors are maintained or lost
Two new studies into lizard colors reveal how one species maintains its colorful diversity while others are losing their ancient colors. And the changes are being driven by the biological equivalent of rock-paper-scissors.
Medical Xpress / SARS-CoV-2 is on the decline in animals, researchers find
During the first few years of the COVID-19 pandemic, the virus SARS-CoV-2 was detected in an increasing number of non-human animal species. This included many wild animal species as well as domestic animals such as dogs and ...
Phys.org / Scientists find more active black holes in dwarf and Milky Way-sized galaxies by cutting through glare of star formation
Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active black holes.
Tech Xplore / Coal tailings could solve United States' need for rare earth elements
Rare earth elements are an easy-to-find, hard-to-refine resource critical for everything from magnets and electronics to batteries and catalysts for chemical reactions. Since the 1980s, a race has been on between the United ...
Phys.org / Language shapes visual processing in both human brains and AI models, study finds
Neuroscientists have been trying to understand how the brain processes visual information for over a century. The development of computational models inspired by the brain's layered organization, also known as deep neural ...
