Phys.org / US data shows Arctic winter sea ice could break last year's record low
Arctic sea ice is headed for one of its smallest winter peaks on record, an AFP review of U.S. data showed Wednesday, as climate change shrinks the region's frozen cover and heightens geopolitical tensions.
Phys.org / 2D topological Kondo insulator observed in a moiré superlattice
When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give rise to the so-called ...
Phys.org / Recent pandemic viruses jumped to humans without prior adaptation, study finds
A new University of California San Diego study published in Cell challenges a long-standing assumption about how animal viruses become capable of sparking human epidemics and pandemics. Using a phylogenetic, genome-wide analysis ...
Medical Xpress / Daily multivitamins may slow biological aging, two-year trial suggests
An analysis led by Mass General Brigham investigators found slower aging in older adults after two years of a daily multivitamin, with greater benefits for those who began the trial with accelerated biological age
Medical Xpress / Alternative breast cancer treatment tied to about four times higher mortality, nationwide analysis finds
The alternative medicine industry is expanding rapidly, fueled in large part by the surge of health-related content on social media. This growing trend has become an increasing concern for oncology practitioners and patients, ...
Phys.org / Earth's ice is melting: Where and how fast?
Melting glaciers and ice sheets are raising sea levels while the Arctic is poised to log one of its worst winters on record.
Phys.org / NASA finds extreme star collision in unlikely spot
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this ...
Phys.org / Quantum entanglement offers route to higher-resolution optical astronomy
Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard ...
Phys.org / Could ultrasound help save hedgehogs?
Researchers at the University of Oxford have suggested that ultrasound-repellers could help reduce hedgehog deaths caused by cars. The proposal is based on new findings, published in Biology Letters, which demonstrate for ...
Phys.org / How changes on the Y chromosome may make species reproductively incompatible
When closely related species mate, their offspring sometimes survive but cannot reproduce. This pattern often affects males first, with hybrid males frequently failing to produce functional sperm even when hybrid females ...
Phys.org / Antarctic waters DNA survey discovers many microbial genes new to science
The Southern Ocean—vast, boundless waters surrounding Antarctica—plays an outsized role in global climate, largely thanks to tiny drifting organisms called plankton that soak up carbon. Reporting in Nature Communications ...
Phys.org / Miniature laser technology could bring lab testing into your home
A research team at Chalmers University of Technology, Sweden, has developed new laser technology that could lead to tiny, cost-effective biosensors. The sensors integrate lasers and optics together on a centimeter-sized chip, ...
