X-ray ‘eyes’
Movie directors often make “short” subjects, flicks running sometimes just a few minutes or so. But scientists have begun making much quicker “shorts,” essentially nanofilms. Their goal: catching science in action.

Self-forming envelope holds fluids
These plastic-laced water molecules can create their own protective shell. That can make capsules for holding drugs or for hosting chemical reactions.

Grape scents repel mosquitoes
Safer than DEET, the new compounds could lead to insect repellents that would be affordable even in poor regions where mosquitoes carry malaria.

Cyberspace chemistry earns a Nobel
The achievements behind the 2013 Nobel Prize in chemistry relied on a lot of complex physics. But the computer techniques pioneered by these three men are now saving chemists a lot of work.

Cool Jobs: Repellent chemistry
Chemistry is just one way to repel water in nature. Structure, or the shape of things, is another. To excel at water repellency, the lotus leaf relies on both.

A penny for your health?
Copper is best known as the reddish metal used to make pennies, electrical wiring and weather vanes. But two teen scientists think copper should find its way into medical settings as well. Their data suggest the metal — in bandages or on surfaces — could play a major role in killing some types of bacteria responsible for serious infections.
