Analyze This: Puppies naturally mimic human actions
Unlike cats, whose ancestors hunted alone, dogs evolved from a species that hunted in packs. Being social might explain why pups copy humans.

This biologist uses microwave radiation to save endangered species
Pei-Chih Lee works to preserve genetic material that can help researchers learn more about endangered animals, such as pandas and clouded leopards.
- Environment
Sea life may suffer as plastic bits alter metals in water
This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.
