Phys.org / Smartwatch study shows stadium atmosphere spikes heart rate and stress levels
Fans of DSC Arminia Bielefeld experience matchday excitement far more intensely in the stadium than in front of the television when watching football (soccer). A study from Bielefeld University demonstrates clear differences ...
Tech Xplore / AI-generated text is overwhelming institutions, setting off a no-win 'arms race' with AI detectors
In 2023, the science fiction literary magazine Clarkesworld stopped accepting new submissions because so many were generated by artificial intelligence. Near as the editors could tell, many submitters pasted the magazine's ...
Phys.org / Imaging the Wigner crystal state in a new type of quantum material
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner ...
Phys.org / Climate 'fingerprints' mark human activity from the top of the atmosphere to the bottom of the ocean
The world is warming. This fact is most often discussed for Earth's surface, where we live. But the climate is also changing from the top of the atmosphere to the bottom of the ocean. And there is a clear fingerprint of humanity's ...
Tech Xplore / 'I'm walking here!' A new model maps foot traffic in New York
Early in the 1969 film "Midnight Cowboy," Dustin Hoffman, playing the character of Ratso Rizzo, crosses a Manhattan street and angrily bangs on the hood of an encroaching taxi. Hoffman's line, "I'm walking here!" has since ...
Phys.org / The Amaterasu particle: Cosmic investigation traces its origin
Cosmic rays are extremely fast, charged particles that travel through space at nearly the speed of light. The Amaterasu particle was detected in 2021 by the Telescope Array experiment in the U.S. It is the second-highest-energy ...
Phys.org / Passerine birds' survival tactic overturns long-held assumptions
Passerine (perching) birds make up 60% of all bird species, including some familiar Australian favorites, like the superb fairy-wren and willie wagtail. Until now, they were believed to only be capable of shallow reductions ...
Tech Xplore / City skylines need an upgrade in the face of climate stress
When structural engineers design a building, they aren't just stacking floors; they are calculating how to win a complex battle against nature. Every building is built to withstand a specific "budget" of environmental stress—the ...
Tech Xplore / In the Australian outback, we're listening for nuclear tests—and what we hear matters more than ever
Tires stick to hot asphalt as I drive the Stuart Highway from Alice Springs northward, leaving the MacDonnell Ranges behind. My destination is the Warramunga facility, about 500 kilometers north—a remote monitoring station ...
Phys.org / Experiments clear up confusion over the form of solid methane
Through a combination of high-pressure experiments and optical spectroscopy, physicists have revealed new insights into the structural forms of solid methane. Led by Mengnan Wang at the University of Edinburgh in the UK, ...
Medical Xpress / PRISM reanalyzes 4,400 tumors, reshaping the debate over tumor microbiomes
When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi—microorganisms that—if actually present in tumor tissues—could influence how they grow, evade immunity ...
Phys.org / How superconductivity arises: New insights from moiré materials
How exactly unconventional superconductivity arises is one of the central questions of modern solid-state physics. A new study published in the journal Nature provides crucial insights into this question. For the first time, ...
