Rocks hold clues to ancient die-offs
Rocks that formed during ancient mass-extinction show that the oceans back then had become very warm. That was the last time Earth spewed carbon dioxide into its atmosphere at a rate similar to what is happening today.

Zombie stars: A source of gravitational waves?
Scientists have found indirect evidence that the dense cores of dead stars are making ripples in space, known as gravitational waves. These waves have been predicted but never yet directly “seen.”
