| Scientists discover electric eels hunting in a group Posted: 14 Jan 2021 01:39 PM PST Deep in the Brazilian Amazon River basin, scientists discovered a small, river-fed lake filled with more than 100 adult electric eels. Researchers witnessed the electric eels working together to herd small fish into tightly packed balls. Groups of up to 10 eels periodically split off to form cooperative hunting parties. Those smaller groups then surrounded the prey and launched simultaneous electric attacks. The findings overturn the idea that these serpentine fish are exclusively solitary predators. |
| New state of matter in one-dimensional quantum gas Posted: 14 Jan 2021 01:39 PM PST By adding some magnetic flair to an exotic quantum experiment, physicists produced an ultra-stable one-dimensional quantum gas with never-before-seen 'scar' states - a feature that could someday be useful for securing quantum information. |
| Feces and algorithms: Artificial Intelligence to map our intestinal bacteria Posted: 14 Jan 2021 10:01 AM PST The intestines and their bacteria are sometimes called our 'second brain', but studying these bacteria in their natural environment is difficult. Now researchers have developed a method that uses artificial intelligence to map intestinal bacteria using feces. The researchers thus hope to gain more knowledge of the role played by these bacteria in various diseases. |
| Galaxies hit single, doubles, and triple (growing black holes) Posted: 14 Jan 2021 10:01 AM PST When three galaxies collide, what happens to the huge black holes at the centers of each? A new study using NASA's Chandra X-ray Observatory and several other telescopes reveals new information about how many black holes are furiously growing after these galactic smash ups. |
| Posted: 14 Jan 2021 10:01 AM PST Astronomers have curated the most complete list of nearby brown dwarfs to date thanks to discoveries made by thousands of volunteers participating in the Backyard Worlds citizen science project. The list and 3D map of 525 brown dwarfs -- including 38 reported for the first time -- incorporate observations from a host of astronomical instruments including several NOIRLab facilities. The results confirm that the Sun's neighborhood appears surprisingly diverse relative to other parts of the Milky Way Galaxy. |
| Spectacular fossil discovery: 150 million-year-old shark was one of the largest of its time Posted: 14 Jan 2021 08:19 AM PST A team led by Sebastian Stumpf from the University of Vienna describes an well-preserved skeleton of the ancient shark Asteracanthus. This rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago. The almost complete skeleton shows that Asteracanthus was two-and-a-half meters long, which makes this ancient shark one of the largest of its time. |
