Researchers have discovered evidence of water — enough to fill oceans — embedded in minerals deep beneath the surface of the United States that could alter the current understanding of Earth’s composition and how it was formed. Were this water in liquid form, which it is not, the discovery could be considered the planet’s largest underground water reservoir, researchers said. The team of researchers, led by geophysicist Steve Jacobsen and seismologist Brandon Schmandt, has found pockets of magma about 400 miles beneath Earth’s surface — clear signs of the presence of water, though not in its familiar liquid form. Here is hydrous ringwoodite synthesized from olivine in Jacobson’s laboratory.

A sea creature previously thought to be a sea anemone belongs to an order of it’s own, researchers found. The Relicanthus daphneae lives near deep sea thermal vents in the Pacific and had been considered a giant sea anemone because of it’s boneless, immobile carnivorous state. But while the anemone lost it skeleton over millions of years of evolution, R. daphneae never had them.
