Waters could support isolated life

A team of scientists has mapped the location of hydrogen-rich waters found trapped kilometers beneath Earth's surface in rock fractures in Canada, South Africa and Scandinavia. Common in Precambrian Shield rocks -- the oldest rocks on Earth -- the ancient waters have a chemistry similar to that found near deep sea vents, suggesting these waters can support microbes living in isolation from the surface.
