Meet one of the ‘world’s most interesting’ mathematicians

Angela Tabiri uses her enthusiasm for math to inspire young people — and to highlight African female mathematicians on a YouTube channel.

Fossils

Could Spinosaurus swim? That would make it a game changer

Spinosaurus fossils are challenging the longstanding claim that ancient dinosaurs were never fully aquatic. And some paleontologists still aren’t convinced.

Physics

Much of the sun’s light is green. Why does it look yellow?

Sunlight's peak intensity is at a green wavelength. Here’s why it doesn’t appear that way to us.

Humans

Explainer: What is cancer?

Cancer is a whole collection of diseases with one thing in common: all develop when the body’s cells start dividing out of control.

Materials Science

A beautiful blue butterfly wing offers a new way to study cancer

Once a morpho butterfly wing is placed atop a thin slice of tissue, shining polarized light through it can help reveal how likely breast cancer is to spread.

Brain

Let’s learn about memory

Brain injuries, drug use and other factors can impair our memory. But targeted practice and healthy habits can boost our ability to remember.
