Let’s learn about the Nobel Prize
Nobel Prizes are the highest honors in science. But the prizes are far from perfect measures of scientific impact.
- Space
Spacecraft need an extra boost to travel between stars
Star Wars makes space travel look easy by breaking the laws of physics. Off-screen, the technology for spacecraft to reach other worlds doesn’t exist yet.
- Archaeology
Scientists Say: Stone Age
This vast, mysterious stretch of time marks the dawn of human civilizations.
- Microbes
More than 100 types of bacteria found living in microwave ovens
More than 30 microwave ovens were sampled in a range of different settings. The microbes in them included ones that can cause food poisoning in people.

Explainer: Anatomy of a heartbeat
Here’s how the heart pumps blood to each and every cell of the body. It beats roughly 60 times every minute, starting before we’re born.
- Brain
Zap, zap, zap! Our bodies are electric
Electricity powers key functions in the brain, heart and bone. Scientists are working to understand those currents to improve our health and moods.
