Phys.org / Satellite observations put stratospheric methane loss higher than models predicted
Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30% of modern global warming ...
Phys.org / How an ancient seafloor turned Arkansas into 'Sharkansas,' a shark fossil hotspot
Most shark fossils are just teeth—their cartilage skeletons usually decay long before they can fossilize. But in northwestern Arkansas, a series of geological sites known as the Fayetteville Shale has preserved dozens of ...
Phys.org / Laser‑written glass chip pushes quantum communication toward practical deployment
As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of physics instead of computational ...
Phys.org / Supercomputer simulations test turbulence theories at record 35 trillion grid points
Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence ...
Phys.org / Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve ...
Phys.org / Climate change could halve areas suitable for cattle, sheep and goat farming by 2100
A new study conducted at the Potsdam Institute for Climate Impact Research (PIK) shows that grassland-based grazing systems—currently covering a third of Earth's surface and representing the world's largest production system—will ...
Phys.org / Why only a small number of planets are suitable for life
For life to develop on a planet, certain chemical elements are needed in sufficient quantities. Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store and transmit genetic ...
Phys.org / A smashing success: Relativistic Heavy Ion Collider wraps up final collisions
Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion Collider (RHIC) and ...
Phys.org / Tiny Enceladus exercises giant electromagnetic influence at Saturn
A major study by an international team of researchers using data from the NASA/ESA/ASI Cassini spacecraft has revealed a lattice-like structure of crisscrossing reflected waves that flow downstream behind the moon in Saturn's ...
Phys.org / From fins to fingers: How nature 'redeployed' ancient genes to shape limbs
How did the complexity of many organisms living today evolve from the simpler body plans of their ancestors? This is a central question in biology. Take our hands, for example: Every time we type a message on our mobile phone, ...
Phys.org / Stellar remnants may solve mystery of missing mass in galaxy clusters
Under the leadership of the University of Bonn, a research team led by Prof. Dr. Pavel Kroupa from the Helmholtz Institute for Radiation and Nuclear Physics has discovered that galaxy clusters are about twice as heavy as ...
Phys.org / The future of eco-friendly cooling: Enhancing efficiency and sustainability of magnetic refrigerants
Conventional air conditioners and refrigerators rely on vapor-compression cycles and chemical refrigerants that contribute significantly to global warming. Magnetic refrigeration offers a cleaner alternative using the magnetocaloric ...
