Scientists Say: Graphene
This is a single layer of carbon atoms, linked to each other in a flat sheet. It’s super strong, super flexible and conducts current, too.

Scientists Say: Photochromic
Photochromic chemicals change shape when exposed to a specific wavelength of light. The shape change changes the chemical’s color.

Scientists Say: Catalyst
Sometimes a chemical reaction can take a while. If speed is needed, a catalyst can help.

Trees can make summer ozone levels much worse
The greenery can release chemicals into the air that react with combustion pollutants to make ozone. And trees release more of those chemicals where it gets really hot, a new study finds.
