The plumose anenome dines on a surprising menu item: ants. A new study digs into how they became part of a marine food chain.

"These incredibly abundant and ecologically-important marine animals have a neat trick to beat the physics of their environment..."

Roundup, one of the world's most popular weed killers, can make ecosystems more vulnerable to pollution and climate change.

Plankton fossils from the Pliocene, an era with CO2 levels similar to those today, may help scientist predict what's in store for our climate in the future.

As a runaway climate scenario looms, scientists are hurrying to fully understand Earth's largest carbon sink: its oceans.
