Newfound desert soil community lives on sips of fog
Lichens and other fungi and algae team up to form a 'grit-crust' on the parched soil of Chile’s Atacama Desert. Those species slake their thirst with moisture from coastal fog.

Small swimmers may play huge role in churning the seas
Hoards of migrating shrimp and krill can cause large-scale water movements in the ocean, a new study suggests.

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.
