Development of a lithium-air battery with an energy density over 500 wh/kg Posted: 20 Jan 2022 11:07 AM PST Researchers have developed a lithium-air battery with an energy density over 500Wh/kg -- significantly higher than currently lithium ion batteries. The research team then confirmed that this battery can be charged and discharged at room temperature. In addition, the team found that the battery developed by the team shows the highest energy densities and best cycle life performances ever achieved. These results signify a major step toward the practical use of lithium-air batteries. |

Branching worm discovered in Japan named after Godzilla’s nemesis Posted: 20 Jan 2022 11:07 AM PST Branching marine worms are bizarre creatures with one head but a body that branches over and over again into multiple posterior ends. Until now, only two species of these curious beasts, thought to be extremely rare, were known. However, a third species has now been discovered and described. The worm, named Ramisyllis kingghidorahi after King Ghidorah, Godzilla's monster enemy, was discovered in Japan. |

Research in mice identifies neurons that control locomotion Posted: 20 Jan 2022 09:54 AM PST For more than a century, scientists have known that while the commands that initiate movement come from the brain, the neurons that control locomotion once movement is underway reside within the spinal cord. Researchers now report that, in mice, they have identified one particular type of neuron that is both necessary and sufficient for regulating this type of movement. These neurons are called ventral spinocerebellar tract neurons (VSCTs). |

Researchers simulate behavior of living 'minimal cell' in three dimensions Posted: 20 Jan 2022 09:53 AM PST Scientists report that they have built a living 'minimal cell' with a genome stripped down to its barest essentials -- and a computer model of the cell that mirrors its behavior. By refining and testing their model, the scientists say they are developing a system for predicting how changes to the genomes, living conditions or physical characteristics of live cells will alter how they function. |

Here’s why whales don’t drown when they gulp down food underwater Posted: 20 Jan 2022 09:53 AM PST Ever wondered whether whales can burp, and why they don't drown when they gulp down gallons of water and krill? New research may just hold the answer. Researchers found that lunge-feeding whales have an 'oral plug', a fleshy bulb in their mouths that moves backwards to seal off the upper airways during feeding, while their larynx closes to block the lower airways. |
Supplement appears to boost muscle, mitochondria health Posted: 20 Jan 2022 09:53 AM PST An oral supplement intended to stimulate a natural body process appears to promote muscle endurance and mitochondrial health in humans.

Impossible material made possible inside a graphene sandwich Posted: 20 Jan 2022 07:34 AM PST Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating properties determined by quantum mechanics. |

Scientists trace the path of radioactive cesium in the ecosystem of Fukushima Posted: 20 Jan 2022 06:12 AM PST In 2011, the nuclear accident at Fukushima, Japan, resulted in the deposit of radioactive cesium (radiocesium) into habitats in the vicinity. A decade after the accident, researchers have collated the complicated dynamics of radiocesium within forest-stream ecosystems. Understanding radiocesium flow in the environment could help mitigate contamination and inform future containment strategies. |

Posted: 19 Jan 2022 04:42 PM PST Scientists monitoring the giant A68A Antarctic iceberg from space reveal that a huge amount of fresh water was released as it melted around the sub-Antarctic island of South Georgia. 152 billion tonnes of fresh water -- equivalent to 20 x Loch Ness or 61 million Olympic sized swimming pools, entered the seas around the sub-Antarctic island of South Georgia when the megaberg A68A melted over 3 months in 2020/2021, according to a new study. |
Hubble finds a black hole igniting star formation in a dwarf galaxy Posted: 19 Jan 2022 04:41 PM PST Often portrayed as destructive monsters that hold light captive, black holes take on a less villainous role in the latest research from NASA's Hubble Space Telescope. A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up. The black hole is apparently contributing to the firestorm of new star formation taking place in the galaxy. The dwarf galaxy lies 30 million light-years away, in the southern constellation Pyxis. |

Kombucha water filters can resist clogging better than commercial options Posted: 19 Jan 2022 12:52 PM PST Commercially available ultrafiltration membranes that purify water are expensive and get clogged easily by particles and microorganisms. Recently, living filtration membranes were reported as an alternative sieving material. Grown from kombucha cultures, the filters are dense, stacked sheets of bacterial cellulose. Now, researchers show that these living membranes are more resistant to clogging and biofouling, making them more efficient and less expensive to use than conventional ones. |

How many black holes are out there in the universe? Posted: 19 Jan 2022 12:52 PM PST A new study has investigated stellar mass black holes, which are black holes with masses between a few to some hundred solar masses, that originated at the end of the life of massive stars. According to the study, a remarkable amount of around 1 percent of the overall ordinary matter of the universe is locked up in stellar mass black holes. Astonishingly, the researchers have found that the number of black holes within the observable universe at present time is about about 40 times 10 to the exponent 18. |
Review reports improved transparency in antidepressant drug trials Posted: 19 Jan 2022 11:28 AM PST New research suggests manufacturers of newly developed antidepressant drugs have become more forthcoming about clinical trials that don't pan out. While the new findings are encouraging, they still hint at a fundamental shortcoming in medicine: A reliance of studies selectively reported in scientific literature, as opposed to the unvarnished results of clinical trials reported to the Food and Drug Administration. |
'Decoy' protein works against multiple SARS-CoV-2 variants, researchers report Posted: 19 Jan 2022 11:28 AM PST A drug treatment that acts as a decoy against SARS-CoV-2 was highly effective at preventing death and lung damage in humanized animal models of severe COVID-19 disease. The study suggests that the drug has the potential to treat COVID-19 patients, including those who are infected with aggressive SARS-CoV-2 variants. |
