| NASA's Perseverance Mars rover extracts first oxygen from Red Planet Posted: 21 Apr 2021 12:49 PM PDT The milestone, which the MOXIE instrument achieved by converting carbon dioxide into oxygen, points the way to future human exploration of the Red Planet. |
| Carbon dioxide-rich liquid water in ancient meteorite Posted: 21 Apr 2021 12:12 PM PDT Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system. |
| Mice master complex thinking with a remarkable capacity for abstraction Posted: 21 Apr 2021 09:46 AM PDT Categorization is the brain's tool to organize nearly everything we encounter in our daily lives. Grouping information into categories simplifies our complex world and helps us to react quickly and effectively to new experiences. Scientists have now shown that also mice categorize surprisingly well. The researchers identified neurons encoding learned categories and thereby demonstrated how abstract information is represented at the neuronal level. |
| Bi-stable pop-up structures inspired by origami Posted: 21 Apr 2021 09:46 AM PDT Researchers have developed bi-stable inflatable structures inspired by origami. |
| Cracking open the mystery of how many bubbles are in a glass of beer Posted: 21 Apr 2021 09:45 AM PDT After pouring beer into a glass, streams of little bubbles appear and start to rise, forming a foamy head. As the bubbles burst, the released carbon dioxide gas imparts the beverage's desirable tang. But just how many bubbles are in that drink? By examining various factors, researchers estimate between 200,000 and nearly 2 million of these tiny spheres can form in a gently poured lager. |
| Bubble with titanium trigger titanic explosions Posted: 21 Apr 2021 09:45 AM PDT Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode. |
| Enormous flare from sun's nearest neighbor breaks records Posted: 21 Apr 2021 09:45 AM PDT On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri -- a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun. |
| Camera traps find endangered dryas monkeys Posted: 21 Apr 2021 06:25 AM PDT The Endangered dryas monkey is one of Africa's most mysterious primates. They are difficult to find because they live in dense vegetation in secondary forest thickets. Using non-invasive research and no-flash camera traps from 2014 to 2019, scientists have confirmed the occurrence of the dryas monkey at seven locations in the Democratic Republic of the Congo spanning a total area of 3,453 square kilometers, based on opportunistic reports provided by local village residents and park patrols. |
| Outback radio telescope discovers dense, spinning, dead star Posted: 21 Apr 2021 06:25 AM PDT Astronomers have discovered a pulsar -- a dense and rapidly spinning neutron star sending radio waves into the cosmos -- using a low-frequency radio telescope in outback Australia. The new pulsar is located more than 3,000 light-years from Earth and spins about once every second. Pulsars are used by astronomers for applications including testing the laws of physics under extreme conditions. |
| Energy unleashed by submarine volcanoes could power a continent Posted: 21 Apr 2021 05:29 AM PDT Volcanic eruptions deep in our oceans are capable of extremely powerful releases of energy, at a rate high enough to power the whole of the United States, according to new research. |
| Physicists map new route to control sound in thin films Posted: 16 Apr 2021 09:01 AM PDT In a new paper, physicists describe a theoretical path to make artificial composite thin films in which sound waves can be stopped, reversed and even stored for later use. |
