A single chemical may draw lonely locusts into a hungry swarm
Swarms of locusts can destroy crops. Scientists have discovered a chemical that might make locusts come together in huge hungry swarms.
- Agriculture
Scientists Say: Carbohydrate
Carbohydrates are molecules with carbon, oxygen and hydrogen. Animals break down these chemicals in food to get energy.

Working up a sweat may one day power up a device
Tech that turns sweat into power may make for greener gadgets. A new device uses perspiration to charge a supercapacitor and run a sensor.
- Chemistry
Scientists Say: Polymer
Polymers can be natural or man-made, but they are all big molecules made up of smaller units linked together.
