In a new paper, he concludes that movement through dark matter may perturb the orbits of comets and lead to additional heating in the Earth’s core, both of which could be connected with mass ...

Two nearby supernovae that exploded about 2.5 and eight million years ago could have resulted in a staggered depletion of Earth's ozone layer, leading to a variety of repercussions for life on Earth.

Reefs have been called underwater cities built by the organisms that inhabit them. The term “reef” usually refers to a coral reef, because corals make the vast majority of reefs today, but in ...

A new study indicates that mass extinctions affect the pace of evolution, not just in the immediate aftermath of catastrophe, but for millions of years to follow. The study’s authors, University of ...
