The SARS-CoV-2 virus may enter and replicate in human cells by exploiting newly-identified sequences within cell receptors, according to work from two teams of scientists….
Over their entire late-Cretaceous reign, the total number of Tyrannosaurus rex that ever lived on Earth was roughly 2.5 billion individuals, according to a new…
In an analysis of thousands of fossil pollen and leaves spanning the Cretaceous-Paleogene (K/Pg) boundary, researchers found that the cataclysmic asteroid impact that resulted in…
Introducing a “bizarre” shark from the Late Cretaceous that, more than 66 million years ago, plied the seas feasting upon plankton while soaring through the…
Using both transit and radial velocity data, researchers discovered Gliese 486 b — a super-Earth exoplanet orbiting the nearby red dwarf star Gliese 486. At…
