Sonoluminescence: When Sound Creates Light
So, a mantis shrimp's claws are pretty strong... so strong that they can produce a bubble that's about as hot as the sun and collapses with a flash of light when they snap... and scientists aren't quite sure how they do it!

The Future of CubeSat Propulsion
CubeSats have a lot of advantages, but they need a way to move and still stay small, and that means new miniaturized propulsion systems that can help us get these tiny spacecraft out into the universe.
