Without aggressive climate mitigation, nearly all tropical western Atlantic coral reefs will be eroding, not growing, by 2100, according to a new study.

As Seas Rise, Corals Can't Keep Up - Eos

Coral reef growth rates in the tropical western Atlantic have slowed to a fraction of what they once were, erasing coastal protection benefits they once offered.

Scientists simulated Enceladus's radiation environment and produced key organic compounds, calling for caution in attributing molecules’ origins.

Space Radiation Can Produce Some Organic Molecules Detected on Icy Moons - Eos

As missions prepare to visit ocean worlds like Enceladus and Europa, new findings show scientists must first learn to distinguish between radiation-made organics and those born in a subsurface sea.
