| Experiment results confirm anomaly suggesting new physics possibility Posted: 16 Jun 2022 12:25 PM PDT New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new interpretation of an aspect of standard model physics, such as the neutrino cross section, first measured 60 years ago. |
| Watching the death of a rare giant star Posted: 16 Jun 2022 11:43 AM PDT Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. By tracing molecular emissions in the outflows around the red hypergiant star VY Canis Majoris, astronomers obtained the first detailed map of the star's envelope, which sheds light on the mechanisms involved in the final stages of extreme supergiant star. |
| Quantum simulator delivers new insight Posted: 16 Jun 2022 11:27 AM PDT A quantum simulator is giving physicists a clear look at spin-charge separation, a bizarre phenomenon in which two parts of indivisible particles called electrons travel at different speeds in extremely cold 1D wires. The research has implications for quantum computing and electronics with atom-scale wires. |
| Martian meteorite upsets planet formation theory Posted: 16 Jun 2022 11:15 AM PDT A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form. |
| 100,000-year-old polar bear genome reveals ancient hybridization with brown bears Posted: 16 Jun 2022 09:16 AM PDT An analysis of ancient DNA from a 100,000-year-old polar bear has revealed that extensive hybridization between polar bears and brown bears occurred during the last warm interglacial period in the Pleistocene, leaving a surprising amount of polar bear ancestry in the genomes of all living brown bears. |
| Posted: 16 Jun 2022 09:15 AM PDT Researchers have identified and reconstructed the first ancient genome of E. coli, using fragments extracted from the gallstone of a 16th century mummy. |
