The hidden identities of water molecules

All water drops might seem the same, but scientists can tell them apart based on something called their isotopic composition. Now, researchers are making maps of how water isotopes vary around the world, and it’s helping them do everything from track migratory animals to solve crimes. Learn more about isotopes and why scientists love them … More The hidden identities of water molecules

Granite planet

Granite is the most common rock in continental crust, but only on Earth. So far, scientists have not found significant amounts of granite on any other planets. What makes ours different? Water. Learn how our oceans have shaped the world we live on in my blog post for Nautilus.

Deep ocean minerals hold clues to the cosmos

The growth of ferromanganese crusts is one of the slowest processes known to science; these dull black minerals add just a few millimeters of girth per million years. That makes them excellent of archives of Earth history, and–if you know what to look for–excellent archives of cosmic history too. In their laminated layers, scientists have … More Deep ocean minerals hold clues to the cosmos
