| Neural nets used to rethink material design Posted: 30 Apr 2021 01:58 PM PDT Engineers are using neural networks to accelerate predictions of how the microstructures of materials evolve. The machine-learning technique should speed the development of novel materials. |
| Branching worm with dividing internal organs growing in sea sponge Posted: 30 Apr 2021 01:58 PM PDT The marine worm Ramisyllis multicaudata is one of only two such species possessing a branching body, with one head and multiple posterior ends. The researchers discovered that the complex body of this worm spreads extensively in the canals of their host sponges. |
| Not just for finding planets: Exoplanet-hunter TESS telescope spots bright gamma-ray burst Posted: 30 Apr 2021 10:54 AM PDT NASA has a long tradition of unexpected discoveries, and the space program's TESS mission is no different. Astrophysicists have discovered a particularly bright gamma-ray burst using a NASA telescope designed to find exoplanets - those occurring outside our solar system - particularly those that might be able to support life. It's the first time a gamma-ray burst has been found this way. |
| Move over CRISPR, the Retrons are coming Posted: 30 Apr 2021 09:04 AM PDT Researchers have created a new gene editing tool called Retron Library Recombineering (RLR) that can generate up to millions of mutations simultaneously, and 'barcodes' mutant bacterial cells so that the entire pool can be screened at once. It can be used in contexts where CRISPR is toxic or not feasible, and results in better editing rates. |
| Posted: 30 Apr 2021 06:31 AM PDT The field of soft robotics has exploded in the past decade, as ever more researchers seek to make real the potential of these pliant, flexible automata in a variety of realms, including search and rescue, exploration and medicine. |
| Small galaxies likely played important role in evolution of the Universe Posted: 30 Apr 2021 06:31 AM PDT A study found evidence of a galaxy in a 'blow-away' state, which could give more insight into the Universe's early stages. |
| Lightning and subvisible discharges produce molecules that clean the atmosphere Posted: 29 Apr 2021 11:19 AM PDT Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical -- OH -- and hydroperoxyl radical -- HO2. |
| Using cosmic-ray neutron bursts to understand gamma-ray bursts from lightning Posted: 28 Apr 2021 10:30 AM PDT Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like - by observing neutrons generated from soil by very large cosmic-ray showers. |
