Phys.org / Pompeii's battle scars linked to an ancient 'machine gun'
The ancient city of Pompeii is one of those archaeological sites that keeps on giving with one discovery after another. While much of what we know about the Roman settlement comes from the eruption of Vesuvius in AD 79, another ...
Phys.org / The discovery of a buried delta on Mars could boost the search for life
There's more evidence that water once flowed on Mars with the discovery of an ancient river delta deep below the surface. NASA's Perseverance rover found it more than 35 meters beneath Jezero Crater using ground-penetrating ...
Phys.org / The Yamna reused sacred spaces in the north Pontic Steppe, study suggests
According to an article published in Antiquity by Dr. Svitlana Ivanova and her colleagues, the Yamna culture's repurposing of older ritual spaces reflects a deliberate appropriation and continuation of sacred spaces. A case ...
Phys.org / 'Miracle': Europe reconnects with lost spacecraft
The European Space Agency announced Thursday it has re-established communication with a spacecraft that is part of its Proba-3 mission, after losing contact with the satellite a month ago.
Phys.org / Clearing the nanoscale bottleneck holding back next-gen electronics
Researchers at UCLA have discovered a way to dramatically improve how electrical current enters perovskite semiconductors, an emerging class of materials with enormous potential for next-generation electronics. Their research ...
Phys.org / DESI maps C-19, an extremely metal-poor Milky Way stellar stream
Using the Mayall 4-meter telescope at Kitt Peak National Observatory, an international team of astronomers has observed C-19—an extremely metal-poor stellar stream in the Milky Way's halo. Results of the observational campaign, ...
Phys.org / Gravitational waves leave imprints on light emitted by atoms, theoretical study predicts
Gravitational waves are ripples in spacetime produced by violent cosmic events, such as the merging of black holes. So far, direct detections have relied on measuring tiny distance changes over kilometer-scale instruments. ...
Phys.org / Engineered nanoparticles show enhanced intrinsic luminescence for biomedical imaging and cancer treatment
The Nanomedicine and Nanotoxicology Group (GNano) at the University of São Paulo's São Carlos Institute of Physics (IFSC-USP) in Brazil has discovered a way to transform hydroxyapatite, a bioceramic material, into a nanoparticle ...
Phys.org / H5N1 in marine mammals is spreading: Research tallies over 50,000 seals and sea lions killed along South America's coast
When the H5N1 highly pathogenic avian influenza virus was discovered on a poultry farm in Asia in 1996, there was little indication that it would become so widespread and so destructive. Within 30 years, it reached every ...
Phys.org / Molecular enhancements help plants light up when they're under attack
Imagine that plants could tell us exactly when they're stressed, infected, or being eaten by insects, by lighting up. A new study led by Dr. Karen Sarkisyan, Head of the Synthetic Biology group at the MRC Laboratory of Medical ...
Phys.org / Invasive grasses may be turning British Columbia's burn scars into the next wildfire
After a wildfire, the flames may fade, but the danger does not. A new study by UBC researchers reveals that burned landscapes remain vulnerable for years, with large areas still bare and at risk of invasion by fast-growing, ...
Phys.org / Ultra-thin MoSe₂ grating traps infrared light in a 40-nanometer layer
Controlling light at the micro- and nanoscale opens up opportunities for a better understanding of the world and the development of technology. As modern electronics approaches the limits of its capabilities, photonics comes ...
