Phys.org / Exposure to burn injuries played key role in shaping human evolution, study suggests
Humans' exposure to high temperature burn injuries may have played an important role in our evolutionary development, shaping how our bodies heal, fight infection, and sometimes fail under extreme injury, according to new ...
Phys.org / Topological antenna could pave the way for 6G networks
Using ideas borrowed from topological photonics, researchers in Singapore, France and the US have designed a compact antenna capable of handling information-rich terahertz (THz) signals. Reporting their results in Nature ...
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 / Glimpsing the quantum vacuum: Particle spin correlations offer insight into how visible matter emerges from 'nothing'
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key feature of virtual particles ...
Phys.org / 2023–2024 El Niño triggered record-breaking sea level spike along African coastlines, study finds
Africa's coastlines are under growing threat as sea levels climb faster than ever, driven by decades of global warming caused by human activity, natural climate cycles, and warming ocean waters. Between 2009 and 2024, the ...
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 / VIP-2 experiment narrows the search for exotic physics beyond the Pauli exclusion principle
The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists has carried out one of ...
Phys.org / Bacteria can survive washing and disinfection in food production plants
Bacteria in food can make you seriously ill, which is why it is so important for the facilities that produce your food to ensure proper hygiene in their production lines. A new doctoral thesis from NTNU has investigated how ...
Medical Xpress / Consuming 2–3 cups of coffee daily associated with lower dementia risk, better cognitive function
A new prospective cohort study by investigators from Mass General Brigham, Harvard T.H. Chan School of Public Health, and the Broad Institute of MIT and Harvard analyzed 131,821 participants from the Nurses' Health Study ...
Phys.org / Physicists clarify key mechanism behind energy release in molybdenum-93
A team of physicists from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences, together with collaborators, has identified the dominant physical mechanism responsible for energy release in the nuclear ...
Medical Xpress / Study of 12 monks finds meditation heightens brain activity, reshaping neural dynamics
Contrary to popular belief, meditation isn't "thinking about nothing." In fact, a new international study on Buddhist monks shows that meditation is a state of heightened cerebral activity in which brain dynamics are profoundly ...
Phys.org / How big can a planet be? With very large gas giants, it can be hard to tell
Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar system, but there are many ...
