The search for life's building blocks on Enceladus just got more complicated. Experiments show that radiation can also produce organics from ingredients found on the icy moon. 🔭 🧪 eos.org/articles/spa...

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.

Without aggressive climate mitigation, nearly all tropical western Atlantic coral reefs will be eroding, not growing, by 2100, according to new research in @nature.com. 🪸🧪 eos.org/articles/as-...

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.
