| Caribbean coral reefs have been warming for at least 100 years Posted: 09 Mar 2022 11:09 AM PST A new analysis outlines 150 years of sea-surface temperature history throughout the Greater Caribbean region, highlighting significant warming trends that have disrupted coral reef ecosystems. |
| Office buildings with infrequent water use may have poor water quality Posted: 09 Mar 2022 11:08 AM PST Low-consumption office buildings with infrequent water use could have chemical and microbiological safety issues, according to a new study. The research could have implications for office buildings used less frequently during pandemic lockdowns, and suggests that regular water testing in commercial buildings may be needed. |
| Giant impact crater in Greenland occurred a few million years after dinosaurs went extinct Posted: 09 Mar 2022 11:08 AM PST Danish and Swedish researchers have dated the enormous Hiawatha impact crater, a 31 km-wide meteorite crater buried under a kilometer of Greenlandic ice. The dating ends speculation that the meteorite impacted after the appearance of humans and opens up a new understanding of Earth's evolution in the post-dinosaur era. |
| Stalagmites trace climate history and impact from volcanic eruptions Posted: 09 Mar 2022 10:18 AM PST The soils and vegetation of Patagonia's fjord regions form a unique and highly sensitive ecosystem that is closely linked to marine ecosystems, sediment deposition and carbon storage in the ocean. A research team has been working on reconstructing the climate history of this region in this extremely wet, rainy and inaccessible fjord and island zone of the Patagonian Andes in southern Chile. Due to its location, the area is a key region for understanding the history of the southern westerly wind belt within the global climate system. |
| Physics and biology explore together the mechanisms of life Posted: 09 Mar 2022 07:44 AM PST Each of our cells contains about 40 million proteins that together perform all the tasks the cell needs to survive. For a smooth action, the right proteins must be concentrated in specific amounts, at a specific time and at a specific location. However, establishing such a delicate distribution requires an extremely precise process, happening at tiny spatial resolutions that standard cell biology tools are often unable to detect. To understand how this mechanism works, researchers have developed a new approach combining genetics and cell biology experiments with physical modelling. Using specific algorithms, they simulated the formation of protein gradients in 3D and throughout time and were able to explain these complex mechanisms. Moreover, their innovative model can be adapted to other biology systems to investigate protein dynamics. |
| Innovative solution for thermal energy storage Posted: 09 Mar 2022 07:44 AM PST A new research article features one major challenge overcome through a remarkably simple idea, opening the door to expanded use of PCMs for energy-efficient heating and cooling. |
| Preparing for when lightning strikes the same place twice, then strikes again Posted: 08 Mar 2022 12:56 PM PST Disasters such as hurricanes, wildfires, floods, tornadoes, and droughts are not only increasing in intensity and frequency, they are also striking the same place multiple times. Yet, to date, disaster research largely focuses on individual events, and fails to account for legacy effects that leave people vulnerable in the wake of repeated disasters. To improve predictive capacity to better prepare for future disasters, an interdisciplinary team of researchers has developed a novel framework for improving scientific understanding of 'recurrent acute disasters' (RADs). Their work was published today in Science Advances. |
