| Was Cascadia's 1700 earthquake part of a sequence of earthquakes? Posted: 20 Apr 2021 01:09 PM PDT The famous 1700 Cascadia earthquake that altered the coastline of western North America and sent a tsunami across the Pacific Ocean to Japan may have been one of a sequence of earthquakes, according to new research. |
| 'Dead clades walking': Fossil record provides new insights into mass extinctions Posted: 20 Apr 2021 01:09 PM PDT Mass extinctions are known as times of global upheaval, causing rapid losses in biodiversity that wipe out entire animal groups. Some of the doomed groups linger on before going extinct, and a team of scientists found these 'dead clades walking' (DCW) are more common and long-lasting than expected. |
| Fearsome tyrannosaurs were social animals Posted: 20 Apr 2021 09:14 AM PDT The fearsome tyrannosaur dinosaurs may not have been solitary predators as popularly envisioned, but social carnivores with complex hunting strategies like wolves. |
| Little Foot fossil shows early human ancestor clung closely to trees Posted: 20 Apr 2021 06:29 AM PDT The fossil provides the oldest, most intact example of the shoulder of a human ancestor ever found. The bones provide telltale clues of how the individual moved and was adapted to climbing, a research team reports. |
| Can extreme melt destabilize ice sheets? Posted: 20 Apr 2021 06:28 AM PDT Researchers have deciphered a trove of data that shows one season of extreme melt can reduce the Greenland Ice Sheet's capacity to store future meltwater - and increase the likelihood of future melt raising sea levels. |
| Rock glaciers will slow Himalayan ice melt Posted: 20 Apr 2021 06:28 AM PDT Some Himalayan glaciers are more resilient to global warming than previously predicted, new research suggests. |
| People have shaped Earth's ecology for at least 12,000 years, mostly sustainably Posted: 19 Apr 2021 03:21 PM PDT New research shows that land use by human societies has reshaped ecology across most of Earth's land for at least 12,000 years. Researchers, from over a dozen institutions around the world, assessed biodiversity in relation to global land use history, revealing that the appropriation, colonization, and intensified use of lands previously managed sustainably is the main cause of the current biodiversity crisis. |
