Team Drills Where Asteroid Hit, Killing Dinosaurs
Geologists are drilling below the seabed of a prehistoric crater created by an asteroid in Mexico that is believed to have killed the dinosaurs.

Scientists hope that retrieved rock cores will contain clues to how life came back in the wake of the cataclysm, and whether the crater itself could have been a home for novel microbial life.
