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.
- Genetics
Experiment: Are fingerprint patterns inherited?
Let’s investigate whether fingerprint patterns are created randomly or whether they are influenced by genetics.

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.
- Physics
A powerful laser can control the paths that lightning takes
In a mountaintop experiment, a laser beamed at the sky created a virtual lightning rod that snagged several bolts.
