The framework they developed builds on current state-of-the-art methods for experimenting with compounds and understanding chemical instabilities. |
| Antabuse may help revive vision in people with progressive blinding disorders Posted: 18 Mar 2022 01:14 PM PDT Animal and cell studies show that as retinal cells die in degenerative eye diseases, they make other cells hyperactive, creating noise that further obscures vision. Tests to prove this in humans are hard to conduct, however. Antabuse, an approved drug used to wean people off alcohol, should tamp down this hyperactivity and conclusively show whether hyperactivity plays a role in humans, potentially driving work to find better drugs to help those with progressive vision loss. |
| Ancient ancestors evolved to be strong and snappy Posted: 18 Mar 2022 01:14 PM PDT Researchers show that the earliest jaws in the fossil record were caught in a trade-off between maximizing their strength and their speed. |

| Posted: 18 Mar 2022 01:14 PM PDT An international research team has found a simple method for growing lung tissue in the lab. These organoids could be used in diagnosis, drug development, and fundamental research. Laboratory studies of lung tissue usually require the removal of large amounts of human or animal tissue. Now scientists have generated tiny quantities of lung tissue, so-called organoids, from just a few body cells in the lab. The tissue forms a three-dimensional structure as it develops, complete with the tiny hairs on the surface typical of lung tissue. These organoids can play an important part in future research on lung diseases, drug development, or personalized medicine. |

Their bones were partially painted, excavated several times and reburied. The findings provide insight into the burial rituals of a fascinating society that lived 9000 years ago. |
| New, possibly arboreal rice rat species discovered in Ecuador Posted: 18 Mar 2022 08:02 AM PDT Three expeditions led an international research to the Cordillera de Kutukú, an isolated mountain range in Ecuador, to find just one specimen of the previously unknown species. The find in the Amazonian side of the Andes underlines the valuable biological role of this mountainous region. |
| Wildfires devastate the land they burn, and they are also warming the planet Posted: 18 Mar 2022 08:02 AM PDT The 2021 wildfire season broke records globally, leaving land charred from California to Siberia. The risk of fire is growing, and a recent report warned that wildfires are on track to increase 50% by 2050. These fires destroy homes, plant life, and animals as they burn, but the risk doesn't stop there. Researchers detail how the brown carbon released by burning biomass in the northern hemisphere is accelerating warming in the Arctic and warn that this could lead to even more wildfires in the future. |
| Turning any camera into a polarization camera Posted: 18 Mar 2022 07:49 AM PDT Researchers have developed a metasurface attachment that can turn just about any camera or imaging system, even off-the-shelf systems, into polarization cameras.

This fundamentally new type of catalysis will offer chemists and biologists a tool for promoting and controlling molecular recognition and self-assembly, enabling them to build complex structures. |
| Industrial discharge is the dominant mercury source in Korea’s west coast Posted: 18 Mar 2022 06:21 AM PDT Researchers have used mercury (Hg) stable isotopes to verify the Hg sources in the sediment and fish along the west coast of Korea. |
| Visible ocean plastics just the tip of the iceberg Posted: 18 Mar 2022 06:21 AM PDT Simulating a half century of movement and degradation of plastic waste in the ocean, a new study estimates that nearly two-thirds of ocean plastics are outside the reach of current monitoring methods. Furthermore, the study suggests that the estimated 25.3 million metric tons of total ocean plastics may represent only 5% of all mismanaged plastic waste to date, with the rest still on land. |

| As oceans warm, marine cold spells are disappearing Posted: 17 Mar 2022 01:34 PM PDT Marine cold spells are cold versions of heat waves: periods of exceptionally cold water, able to hurt or help the ecosystems they hit. Today, the oceans experience just 25% of the number of cold spell days they did in the 1980s, and cold spells are about 15% less intense, researchers found. Weaker cold spells could mean they're less likely to cause mass die-off events, but having fewer cold spells also means refuges and recovery periods from marine heat waves are disappearing. |
