Saturday Citations: Einstein revisited (again); Atlantic geological predictions; how the brain handles echoes

Einstein's inexhaustible field equations just keep on predicting weird stellar objects, and the latest one is a doozy—so strap on your helmet, inside of which is another helmet, encasing still yet another helmet. This headgear is modeled on a weird solution to the field equations described below, along with an interesting neural study involving human speech in reverberant environments and predictions for the Atlantic Ocean over the next 20-odd-million years.
