‘Chaos terrains’ on Jupiter’s moon Europa, grasshopper teeth, and a new biopolymer.

An artist’s interpretation of liquid water on the surface of the Europa spewing from cryovolcanoes (left) and pooling beneath chaos terrain (right). A recent study led by The University of Texas at Austin examined how water associated with chaos terrains could help transport oxygen from the moon’s surface to its liquid water ocean.
