Phys.org / Dying radio galaxies suggest a shorter, more dynamic afterlife for black hole jets
Astronomers have uncovered a previously underexplored population of faint, rapidly fading remnant radio galaxies, offering new insights into what happens after supermassive black holes stop powering their enormous radio jets.
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 / '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 / 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 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.
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 / 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 / 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 / Novel plastic turns into a gas when heated—then reforms once cooled
In a study published in Macromolecules, researchers introduce a novel polymer that could simplify how materials are applied, removed and recycled by eliminating several complex processing steps used today.
Phys.org / Robotic ocean glider reveals giant phytoplankton chains in the Mediterranean Sea
Scientists at Scripps Institution of Oceanography at UC San Diego and the Mediterranean Institute of Oceanography in Marseille, France, have discovered something surprising in the Mediterranean Sea: giant chains of phytoplankton.
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 / Experiment shows how AI discoveries can shape human cultural evolution
Artificial intelligence can develop solutions that humans would be unlikely to discover on their own. But what happens when machines do more than solve individual problems and actually discover entirely new solution strategies? ...
