Colossal, a genetics startup, has birthed three pups that contain ancient DNA retrieved from the remains of the animal’s ...

A research team linked nearby stellar explosions to at least one, possibly two, mass die-offs after calculating the supernova rate of stars closest to the sun in the past 1 billion years.

They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.

They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.

Deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in ...

Instead, the team hypothesized a stellar explosion may have been a potential factor in the Late Devonian extinction event 372 million years ago and one at the end of the Late Ordovician 445 ...
