Washing your jeans too much might pose risks to the environment
Jeans shed thousands of denim fibers in every wash. Those fibers, and the chemicals used to treat them, now are showing up in even the Arctic Ocean.

New solution for carbon dioxide: Turn it into ‘green’ fuel
Chemists have created a new way to convert carbon dioxide into ethanol. It might one day help remove excess CO2 — a greenhouse gas — from the air.

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.
