When T. rex Dominated, Medium-Sized Predators Disappeared – Replaced by Juvenile Tyrannosaurs

New research from UMD shows ecology changed for tyrannosaurs as they grew up. Slender, agile young tyrannosaurs (left) hunted different prey and did so in a different fashion than the much larger, powerful jawed adults (right).

Structural Changes Identified in COVID Alpha and Beta Variants – Suggests Need for Updated Vaccine Booster

Structural Changes Identified in COVID Alpha and Beta Variants – Suggests Need for Updated Vaccine Booster

Mutations in the SARS-CoV-2 variants cause changes in the electrostatic potential (electric charge at rest) on the spike surface. Here, positively charged areas are shown in blue and negatively charged areas in red. In the Beta variant, the receptor-binding domain (RBD) and N-terminal domain (NTD) have changed substantially, affecting the ability of antibodies to bind…

“Invisible” Gold – Scientists Discover “Fool’s Gold” Is Not So Foolish After All

Curtin University research has found tiny amounts of gold can be trapped inside pyrite, commonly known as ‘fool’s gold’, which would make it much more valuable than its name suggests. This study, published in the journal Geology in collaboration with the University of Western Australia and the China University of Geoscience, provides an in-depth analysis…
