Physicists at ETH Zurich and the University of Grenoble have developed a new theoretical framework that helps understand how quantum processes are limited by classical space-time. The researchers have created no-go theorems that limit quantum processes such as quantum indefinite causal order (ICO) in space-time causality. These theorems demonstrate that ICO processes can be embedded…
Researchers at the Athinoula A Martinos Center for Biomedical Imaging have successfully developed a human brain-scale magnetic particle imaging (MPI) system, a significant breakthrough in medical imaging technology. The new system, which uses superparamagnetic iron oxide nanoparticles (SPIONs) to visualize the brain, has demonstrated a spatial resolution of about 7 mm and a temporal resolution…
Physicists at CERN’s ALICE Collaboration have made a groundbreaking discovery, finding the first evidence for antihyperhelium-4, a heavier version of antihelium-4. This antimatter hypernucleus contains two antiprotons, an antineutron, and an antilambda baryon. The detection was made by analyzing data from lead nuclei collisions at the Large Hadron Collider (LHC) in Switzerland. This finding helps…
Physicists at the University of Nottingham have made a groundbreaking discovery in the field of magnetism by imaging altermagnets in detail for the first time. The team used a technique developed at the MAX IV international synchrotron facility in Sweden to map the magnetic domains in manganese telluride (MnTe) down to the nanoscale level. This…
Researchers at Stanford University have made a groundbreaking discovery in the field of nanoelectronics. They have created very thin films of niobium phosphide, a non-crystalline topological semimetal, that conduct electricity better than copper, even in non-crystalline films. This breakthrough could aid the development of ultrathin low-resistivity wires for nanoelectronics applications, enabling the creation of smaller…
An international team of researchers has made a groundbreaking discovery in brain analysis, developing new techniques that consider interactions between three or more regions of the brain. This breakthrough could lead to a deeper understanding of human brain activity and potentially aid in the diagnosis and treatment of neurological disorders. The team’s approach combines topological…
Physicists at Penn State and Columbia University have made a groundbreaking discovery, spotting the “smoking gun” signature of semi-Dirac fermions, a type of quasiparticle predicted by theorists 16 years ago. These quasiparticles exhibit a unique property, behaving like they have mass only when moving in a certain direction. The team used a crystal of the…
A team of astronomers has discovered that Sun-like stars produce “superflares” around once every 100 years, which is a significant increase from previous estimates of every 3000 to 6000 years. This finding could have important implications for forecasting space weather and understanding the potential impact on Earth’s upper atmosphere, electrical grids, and radio communications. The…
Physicists in the US have made a significant breakthrough in the development of nuclear clocks, a technology that could revolutionize timekeeping and open up new possibilities for scientific research. By using physical vapour deposition (PVD) to create layers of thorium fluoride, researchers have been able to reduce the amount of expensive and radioactive thorium-229 needed…
Researchers at the University of Strathclyde have made a groundbreaking discovery in recycling colloidal quantum dots used in supraparticle lasers. The team developed a simple and practical technique to recover 85% of the quantum dots, which can be reused to build new lasers with a photoluminescence quantum yield comparable to those made from new particles….
