New theory may at last explain a swamp’s ghostly will-o’-the-wisps
Chemists have spotted tiny zaps of electricity moving between “swamp-gas” bubbles. Could they ignite methane gas to glow as dancing blue flames?

Could we ever build the tech to shrink ourselves?
The atoms that make us up couldn’t be shrunk or smashed closer together — at least, not without catastrophic consequences.

How to make a pitched ball curve to your will
A range of tricks pitchers use to get curve all come down to the thin layers of air next to the ball — and how a ball’s spin and seams affect them.

Lasers can eavesdrop on microbes, including viruses
They can sometimes identify not only the types, but also how many there are. One day, lasers might be able to keep track of what germs are around us.

This device creates rainbows of sound
A plastic structure separates the pitches in mixed sounds like white noise, much like a rainbow spreads out colors of light.

How polarized and UV-blocking sunglasses protect our eyes
Their filters can cut glare to help us see more clearly. The best ones also filter out the sun’s UV rays — even on cloudy days — to limit eye damage.
