Researchers develop framework for databasing properties of crystal defects

Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in semiconductors like silicon are the backbone of modern technology. Despite their importance, point defects are notoriously difficult to simulate and characterize, particularly across wide regions of the…

Australian Marsupials Fear Humans Far More Than Any Other Predator, New Study Shows

Scientists have experimentally demonstrated that kangaroos, wallabies and other Australian marsupials most fear the human ‘super predator,’ fleeing humans 2.4 times more often than any other predator. The post Australian Marsupials Fear Humans Far More Than Any Other Predator, New Study Shows appeared first on Sci.News: Breaking Science News.  Scientists have experimentally demonstrated that kangaroos,…

Drones validate walrus counts in satellite images from space

In the first successful attempt to calibrate walrus counts from satellite imagery, scientists used drones to validate animal counts in Svalbard, Norway. On this International Day for Biological Diversity, the researchers describe how this study is a big step towards using satellite imagery as a non-invasive method to monitor walruses in the Arctic. In the first…
