The oldest water, found buried in a mine, serves as a time capsule of the environment that existed 2.6 billion years ago. An interesting video explores science news from 2013—more specifically, the oldest water ever discovered and the discovery of astatine's ionization potential. These discoveries are important because one reinforces that life on other planets could be buried (as the water was), and the astatine potential is important in the treatment of cancers.
