The Underocean

Whitecoats discover a huge underground ocean that's several times the total volume of the surface oceans, (which is really just one big ocean when you think about it). It's not nearly as fascinating as it first seems, however, since most of the water is locked up as moisture in rocks. No strange, undiscovered creatures swimming about in eternal darkness or underground civilizations or anything cool like that.

The new research lends credence to theories that our oceans originated on Earth.

Um... as opposed to where, exactly? Look, I understand that good science doesn't take anything on assumption, but it seems pretty bloody obvious the oceans formed as part of the planet. Unless it was those space whales from Star Trek who brought all the water here. I rather liked them; they tried to destroy San Francisco, after all.
