Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies
Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
Phys.org / Quantum entanglement pushes optical clocks to new precision
By replacing single atoms with an entangled pair of ions, physicists in Germany have demonstrated unprecedented stability in an optical clock. Publishing their results in Physical Review Letters, a team led by Kai Dietze ...
Phys.org / Mediterranean wetland under pressure, report shows
On World Wetlands Day, the recent report released by the Mediterranean Wetlands Observatory (MWO) warns that despite their vital importance for populations and biodiversity, Mediterranean wetlands remain fragile ecosystems, ...
Phys.org / Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics
A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation ...
Phys.org / How a certain form of dark matter may lead to the generation of cosmological magnetic fields
Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields remain poorly understood. ...
Phys.org / Physicists explain the exceptional energy-harvesting efficiency of perovskites
Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar ...
Phys.org / Rocket re-entry pollution measured in atmosphere for first time
When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacuglar fireball that streaked across Europe's skies, delighting stargazers and sending a team of scientists rushing toward ...
Phys.org / One of the ocean's saltiest regions is freshening: What it means for circulation
The southern Indian Ocean off the west coast of Australia is becoming less salty at an astonishing rate, largely due to climate change, new research shows.
Phys.org / The Hubble tension: How magnetic fields could help solve one of the universe's biggest mysteries
It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.
Medical Xpress / Drug-resistant salmonella linked to moringa supplement
It's often touted as the "miracle tree" for its dense nutrient profile, but a popular moringa supplement is at the center of a superbug outbreak.
Tech Xplore / Laser-etched glass can store data for 10,000 years, Microsoft says
Thousands of years from now, what will remain of our digital era? The ever-growing vastness of human knowledge is no longer stored in libraries, but on hard drives that struggle to last decades, let alone millennia.
Medical Xpress / First AHA/ACC acute pulmonary embolism guideline: Prompt diagnosis and treatment are key
Early detection and prompt treatment of acute pulmonary embolism (PE), a sudden and potentially life‑threatening blood clot that blocks arteries in the lungs, is critical. Comprehensive recommendations for the evaluation, ...
