Phys.org / AI governance model inspired by Pope Leo XIV aims to put ethics first
Researchers at the John Paul II Catholic University of Lublin (KUL) and the University of Eastern Finland have developed a new model of artificial intelligence governance inspired by the teachings of Pope Leo XIV as set out ...
Phys.org / 'Quiet' pulsar suddenly reveals three glitches in 15 years of observations
Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. ...
Phys.org / From strays to territory bosses: Epigenetics makes cheetahs adaptable
The findings of a new study led by the Leibniz-IZW on Namibian free-ranging cheetahs (Acinonyx jubatus jubatus) demonstrate that epigenetic mechanisms might play an important role in how animals develop different phenotypes ...
Phys.org / Can atmospheric methane removal limit peak warming?
In a new report, the United Nations Environment Program (UNEP) concludes that global warming is expected to exceed 1.5°C within the next few years. This makes two questions increasingly important: how high will temperatures ...
Phys.org / Extreme pressure turns blue pigment into record-long single-atom copper chains
As the electronics in our technology keep shrinking, traditional silicon-based chips are approaching their fundamental physical limits. Yet the wires connecting them might be able to shrink beyond conventional dimensions, ...
Phys.org / How 'hyperselection' is making modern life efficient, pleasant—and boring
It's difficult to imagine a song like Queen's 1975 "Bohemian Rhapsody" topping the charts today. Almost six minutes long, it moves through several radically different musical sections and famously ignores the conventional ...
Phys.org / Deep biosphere has endured mountain-building and erosion over hundreds of millions of years
A new study reveals that microbial life deep within Earth has persisted and repeatedly flourished through hundreds of millions of years of mountain-building and erosion. By analyzing minerals, fluids and gases from a 2.3-kilometer-deep ...
Phys.org / Bumpy battery surfaces can masquerade as nanoscale ion pathways, misleading material design
A signal that appears to show ions moving inside a battery may, in fact, be an illusion caused by an uneven surface. A KAIST research team has identified the origin of this type of artifact, which can lead researchers to ...
Phys.org / Betelgeuse's atmosphere is becoming spotty and asymmetric—and a nearby companion could be shaping the pattern
For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, ...
Phys.org / How climate change may amplify the impact of earthquakes in the Arctic
Permafrost refers to permanently frozen ground. The rock is held together by ice, much like cement binds concrete. However, when the ice thaws, the ground becomes weak and unstable. During an earthquake, this can trigger ...
Medical Xpress / MLC1 antibody identified as possible trigger of rare neurological autoimmune disorder
Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease of the central nervous system in which the immune system attacks structures in the brain, spinal cord and optic nerve. It mostly affects astrocytes, ...
Phys.org / Slender crystal's blue-to-yellow glow could make invisible forces visible
Applying pressure to luminescent organic crystals usually brings molecules closer together and weakens their fluorescence. Materials that instead brighten and undergo a large color change are rare, and clear design principles ...
