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 ...

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 ...

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 ...
