Why onions make us cry
Researchers add another piece to the molecular puzzle biochemists have tried to solve for decades — why onions can make our eyes tear up.

Scientists Say: Capsaicin
This chemical is produced by pepper plants and gives them their hot flavor.

Meet the world’s smallest monster trucks
These DNA-scale nano-vehicles surprised chemists. The bonds that hold their atomic building blocks in place grip the wheels more strongly than anyone had expected.
- Chemistry
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.

New ‘magnet’ pulls pesky nonstick pollutants from drinking water
Chemicals that help make pans nonstick can themselves stick around forever in the environment. But a new material can remove them from drinking water.
- Chemistry
Scientists Say: Photochromic
Photochromic chemicals change shape when exposed to a specific wavelength of light. The shape change changes the chemical’s color.
- Chemistry
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.
