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 ...
Tech Xplore / Danish chemist's invention could make counterfeiting a thing of the past
Every year, companies lose revenue when goods are copied or illegally resold. Now, a new digital and legally binding fingerprint developed at the University of Copenhagen makes products impossible to counterfeit. Royal Copenhagen ...
Phys.org / New chemical method makes it easier to select desirable traits in crops
Crops increasingly need to thrive in a broader range of conditions, including drought, salinity, and heat. Traditional plant breeding can select for desirable traits, but is limited by the genetic variation that already exists ...
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 / 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 / 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 ...
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 / 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 ...
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 ...
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 / 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.
Medical Xpress / A stress-related chemical could initiate symptoms of depression
Depression, one of the most prevalent mental health disorders worldwide, is characterized by persistent feelings of sadness, impaired daily functioning and a loss of interest in daily activities, often along with altered ...
