Roughly 80 million years ago in the shallow inland sea that once split North America into eastern and western land masses, a fearsome 33-foot-long (10-meter-long) marine reptile with powerful jaws and tremendous bite-force was one of the apex predators. A type of seagoing lizard called a mosasaur that ruled the oceans at the same time dinosaurs dominated the land, it has now been given a name...

Once it’s gone, the asteroid won’t be back to Earth's neighborhood until...

Johnson & Johnson on Wednesday kicked off a final 60,000-person trial of a single-shot COVID-19 vaccine that potentially would simplify distribution of millions of doses compared with leading rivals using two doses. The company expects results of the Phase III trial by year end or early next year, Dr. Paul Stoffels, J&J's chief scientific officer, said in a joint press conference with officials...

For all the recent talk of global warming, climate historians hunting for past temperature extremes have unearthed what the U.N. weather agency calls a new record low in the Northern Hemisphere — nearly -70 degrees Celsius (-93 F) was recorded almost three decades ago in Greenland. The World Meteorological Organizations publicly confirmed Wednesday the all-time cold reading for the hemisphere:...
