Darkness, not cold or acidification, was the main driver of marine extinctions after the asteroid that killed the dinosaurs.
When a 10-kilometer asteroid struck Earth 66 million years ago, the planet was plunged into darkness—and about 75% of species vanished, including marine life. Now, a new study reveals that the ...
A major Hayward fault quake could shake some Bay Area communities harder than expected because of the ground beneath them, new federal simulations show.
The asteroid impact that wiped out the dinosaurs didn’t keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years—and ...
In the long shadow of the asteroid that wiped out the dinosaurs, life appears to have bounced back with surprising speed. A new analysis of sedimentation rates suggests that the first wave of marine ...
Here’s what you’ll learn when you read this story: • Scientists discovered that life rebounded at extraordinary speed after the asteroid impact 66 million years ago, with new plankton species evolving ...
After the Dinosaur-Killing Asteroid Wrecked the Planet, Life May Have Bounced Back Surprisingly Fast

How do you know anything is real? Some things you can see directly, like your fingers. Other things, like your chin, you need a mirror or a camera to see. Other things can’t be seen, but you believe ...
New species may have evolved surprisingly quickly after the asteroid impact that wiped out the nonavian dinosaurs, researchers have found. New plankton species may have appeared less than 2,000 years ...
The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest ...
