'Space Sex' Geckos Come Back Frozen to Death

Oops. A Russian space mission meant to test the effect of weightlessness on the gecko's reproductive system didn't quite go as planned.

How Whale-Watching Might Be Harming Whales

Gazing at whales from a boat may seem like an animal-friendly pursuit, but new research is questioning that idea. Why?
