The universe is repulsive, but in a good way. In 2008, while studying bursts of light emitted from exploding stars, newly named Nobel Laureates Adam Riess, Saul Perlmutter and Brian P. Schmidt discovered one of the most mysterious, yet prevalent, components of our universe: dark energy. The three were using the brightness and color from supernovae to determine the speed with which the universe expanded in the past, versus how fast it is expanding now. What they discovered completely transformed how astronomers view the evolution of space. The growth of our universe through time is accelerating. The culprit? Dark energy.

As EARTH explores in Cold Case Files: Forging Forensic Isoscapes," the potential usefulness of isoscapes is wide-ranging and thrilling: By measuring the isotopic ratios in anything from bones to hair to plants to gems, and then comparing those values (perhaps even changing over time, as bones, plants and teeth grow) with an isoscape, it might be possible to track human geographic origins, identify the source of illicit drugs, detect counterfeit food products and follow the migration of wildlife."

In the Witwatersrand goldfields, not far from bustling Johannesburg, South Africa, more than a century of mining has left the region littered with mounds of waste and underlain by a deep underground network of abandoned mine shafts, which are gradually filling with water. Today, the mines are producing less and less gold and more and more sulfuric acid.
