| Posted: 10 Aug 2021 01:13 PM PDT Novel camera detects the birth of high-energy runaway electrons, which may lead to determining how to prevent damage caused by the highly energetic particles. |
| Researchers use artificial intelligence to unlock extreme weather mysteries Posted: 10 Aug 2021 11:31 AM PDT A new machine learning approach helps scientists understand why extreme precipitation days in the Midwest are becoming more frequent. It could also help scientists better predict how these and other extreme weather events will change in the future. |
| Insidious coral killer invading Palmyra Atoll reef Posted: 10 Aug 2021 11:31 AM PDT The reefs at Palmyra Atoll, a small outlying atoll in the equatorial Pacific Ocean, have been undergoing a shift from stony corals to systems dominated by corallimorphs, marine invertebrates that share traits with both anemones and hard corals. Marine biology researchers discovered that although the invading corallimorph is the same species that has been there for decades, its appearance recently changed, and it became much more insidious. |
| Urban experimentation can help develop sustainable policies Posted: 10 Aug 2021 09:11 AM PDT A new study offers an outline of the requirements and research challenges involved in designing effective policies to meet sustainability goals for cities. |
| Speed and absorption key to optimizing new type of rechargeable battery Posted: 10 Aug 2021 07:47 AM PDT Rechargeable, lithium sulfur batteries are promising candidates to sustainably meet the world's energy demands, and a new study has put them one step closer to becoming readily available. |
| Nitrogen inputs in the ancient ocean Posted: 06 Aug 2021 07:43 AM PDT It was long assumed that cyanobacteria were mainly responsible for fixing nitrogen on early Earth, thus making nitrogen available to the biosphere. Researchers now show that purple sulfur bacteria could have contributed substantially to nitrogen fixation under the conditions prevailing in the Proterozoic ocean. |
