Phys.org / Star cluster discovery could change how scientists measure the universe
University of Missouri researchers have uncovered evidence that challenges one of astronomy's most trusted assumptions, a breakthrough that could reshape how scientists measure galaxies and reconstruct the history of the ...
Phys.org / Satellite constellations could create spiraling space debris
To date, close to 30,000 satellites have been launched into Earth's orbit, leading to mounting concerns over the debris created when they collide. In a new analysis posted to the preprint server arXiv, Hugh Lewis of the University ...
Phys.org / Three supermassive black holes discovered in a single galaxy for the first time
An international team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has identified three actively accreting supermassive black holes in the galaxy J0148-4214. Matter is falling into the black ...
Phys.org / Cosmic filaments help set first limits on dark matter's decay into gravitons
Composing some 85% of the universe's total mass, dark matter betrays its presence only through gravity, unlike ordinary matter. Yet through new research published in Physical Review D, a team led by David Dunsky of New York ...
Tech Xplore / Should people marry AI agents?
The widespread use of conversational platforms such as ChatGPT and Gemini is raising important new ethical, anthropological and legal questions regarding the potential risks, misuses and shortcomings of artificial intelligence ...
Phys.org / New CERN measurement challenges conventional models of how gluons behave inside atomic nuclei
A University of Kansas physicist played a leading role in a CERN study showing that two rival explanations for how gluons behave inside atomic nuclei can now be experimentally distinguished.
Phys.org / River shipping emits nearly one-quarter of global shipping CO₂, analysis finds
River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make ...
Phys.org / Long-sought Zhang-Rice singlet visualized directly in cuprate superconductor
Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity ...
Phys.org / Recyclable glue bonds underwater in seconds and holds for years
Most glues need a dry surface to stick properly. Bonding materials underwater is challenging because water forms a thin film on any surface, so instead of an adhesive touching a material directly, it touches a layer of water, ...
Phys.org / Famous oddball quasar isn't X-ray weak after all, astronomers say
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Medical Xpress / Supportive workplaces key to retaining experienced NHS nurses, study finds
A new large-scale survey of NHS nurses by the University of Southampton and the University of Portsmouth has revealed what matters most to them.
Tech Xplore / Why AI may boost carbon emissions instead of cutting them
AI data centers get a bad rap, not least because of concerns that they drive climate change by consuming massive amounts of electricity. But one potentially larger impact of AI on global carbon emissions may be that it's ...
