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 / 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, ...
Medical Xpress / Can medical AI lie? Large study maps how LLMs handle health misinformation
Medical artificial intelligence (AI) is often described as a way to make patient care safer by helping clinicians manage information. A new study by the Icahn School of Medicine at Mount Sinai and collaborators confronts ...
Dialog / Scientists advance multi-purpose photocatalyst for clean hydrogen production and agricultural pollutant degradation
Can we use nothing more than sunlight and inexpensive materials to produce clean hydrogen fuel while also removing toxic pollutants from water? That question shaped our recent work with γ-In2S3, a semiconductor that has ...
Medical Xpress / Structural differences found in brains of people with panic disorder
Panic disorder (PD) is a mental health disorder characterized by recurring panic attacks, episodes of intense fear and anxiety accompanied by physical sensations and physiological responses such as a racing heart, shortness ...
Tech Xplore / Scientists camouflage heart rate from invasive radar-based surveillance
It's a typical workday and you sign onto your computer. Unbeknownst to you, a high-frequency sensing system embedded in your work device is now tracking your heart rate, allowing your employer to monitor your breaks, engagement, ...
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 ...
Phys.org / Hubble captures light show around rapidly dying star
This stunning image from NASA's Hubble Space Telescope reveals a dramatic interplay of light and shadow in the Egg Nebula, sculpted by freshly ejected stardust. Located approximately 1,000 light-years away in the constellation ...
Phys.org / Engineered moths could replace mice in studies on antimicrobial resistance
A scientific breakthrough not only promises faster testing for antimicrobial resistance, but also an ethical solution to the controversial issue of using rodents in research. University of Exeter scientists have created the ...
