Scientists have long determined what extinct animals ate by analyzing carbon isotopes locked inside their fossil teeth. Recently researchers have discovered that the isotopic record depends on the animal’s body mass.

In a new study in Science Advances, researchers at Columbia University show that machine learning algorithms could pick out different types of earthquakes from three years of earthquake recordings at Geysers in California. The repeating patterns of earthquakes appear to match the seasonal rise and fall of water-injection flows into the hot rocks below, suggesting a link to the mechanical processes that cause rocks to slip or crack, triggering an earthquake.
