Phys.org / 'Hidden stars' suggest that distant galaxies are much more massive than they appear
Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. ...
Phys.org / Artificial intelligence acts as an 'ideological chameleon' and may deepen political polarization
Researchers at the State University of Campinas (UNICAMP) in the state of São Paulo, Brazil, examined the ideological stance of large language models—artificial intelligence systems trained to understand and generate human ...
Phys.org / Scientists 'see' nanoscale forces, providing evidence of electric fields at the air‑water interface
Bubbles are round, and we know surface tension does that. But squeeze that gas-liquid boundary into a space only a few tens of nanometers wide—could other forces be at work?
Phys.org / A single asteroid impact may explain the appearance of Mars' moon Deimos
Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a ...
Phys.org / New study links bad bosses with greater work intensity
Work intensity is significantly higher under poor line managers, according to new research led by Bayes Business School (City St George's, University of London) that could have strong implications for global occupational ...
Phys.org / New photonic crystal method improves single-photon sources for quantum networks
Quantum communication promises many advantages over today's standard technologies, including absolutely secure transmission of large amounts of data. However, it requires single photons—and generating them is very difficult. ...
Phys.org / How to better forecast once-in-a-millennium weather events
For all that day-to-day weather forecasts have improved, it remains a challenge to forecast events that might happen once in 1,000 years—like the deadliest heat waves.
Phys.org / Study suggests three-quarters of Indo-Pacific coral reefs could drown as sea levels rise
Nanyang Technological University, Singapore (NTU Singapore) scientists have found that most coral reefs across the Indo-Pacific may struggle to grow fast enough to keep pace with accelerating sea-level rise. Their study found ...
Phys.org / A new mathematical tool to uncover 'who eats whom' in nature
Understanding "who eats whom" is the key to keeping our oceans alive—and our dinner plates full. However, this invisible network that makes up the food chain can unravel with the pull of just one thread. Overfish one species, ...
Phys.org / Secrets of a mystery mammal from Patagonia revealed at last
Eight years of painstaking research on the virtually unknown Wolffsohn's viscacha have helped to shine the spotlight on this super-rare South American rodent and catalyze the conservation action it so urgently needs.
Phys.org / Rare satellite data reveal major limits in flood models
The Kakhovka Dam in southern Ukraine was destroyed on June 6, 2023. The event unleashed a catastrophic flood that forced thousands of residents to evacuate their communities as water levels rose 10 feet (3 meters) above normal.
Phys.org / New bone analysis challenges long-held theory on farming's arrival in Ireland and Great Britain
New research led by University College Dublin has rewritten a key chapter in Irish prehistory, revealing that bones long thought to mark the beginning of farming in Ireland belong to bear and wild boar, not cattle.
