Keeping wine fine for a longer time
Trace metals in wine can be oxidized, producing browning and a nasty smell. A new study shows how we might be able to keep wine fine using chelators. The catch? You may not be able to drink it.
- Life
To cook up life, just add citrate
The theory that RNA spawned the first organisms gets a boost from a common compound.
- Materials Science
Material inspired by dragonfly wings bursts bacteria
Silicon studded with nanostructures could act as antimicrobial coating on medical devices.

Why death smells so deadly
Pinning down animals' odor detectors gives researchers a way to study aversion or attraction to certain objects. And understanding how these behavioral responses work will help researchers clarify why humans feel disgust.

Qingsongite
This newly christened mineral has an atomic structure that’s similar to diamond and nearly as hard.
- Chemistry
Floating beads of water act as tiny test tubes
Chemists exploit pH and ion charge in superheated water drops to create nanoparticles.
- Chemistry
Oxygen shapes growth of graphene
The number of atoms on a copper surface changes the size and rate of the material's crystal development.
- Chemistry
Water squishes into stable shapes, no container required
Nanoparticles lock together to hold water in place for more than a month.
- Planetary Science
