Let’s learn about forensic science

Crime scene investigators analyze evidence with science, to connect criminals to crimes. And it’s often slower and different from what you see on TV.

Humans

Brainwaves of people with coarse, curly hair are now less hard to read

Electrodes weren’t designed for people with coarse, curly hair. A redesign was needed, scientists say.

Earth

Scientists Say: Jurassic

During this time from about 200 million to 145 million years ago, dinosaurs reigned and many animals evolved, including birds and some early mammals.
