Amid streaks of lightning and startling thunder claps on a recent day, I head out into the middle of the marshy wetlands known as the Camargue. I'm with a group of tourists, piled on hay bales in the back of a flatbed trailer pulled by a massive tractor.
The delta in southern France where two branches of the Rhone River meet the sea, the Camargue is the biggest Mediterranean delta after the Nile. The stunning ecosystem is home to pink flamingos, rice paddies and salt, which has been harvested here since the Middle Ages.
Human DNA is the ultimate fingerprint. A single hair can contain enough information to determine someone's identity — a feature that's been invaluable for identifying the unnamed casualties of natural disasters and war. But forensic scientists who use DNA say the technology isn't always available where it's most needed, like in poor countries, or in war zones like Syria.
For several weeks now, two unmanned spy planes have been flying over the Atlantic on an unusual mission: gathering intelligence about tropical storms and hurricanes.
The two Global Hawk drones are a central part of NASA's five-year HS3 (Hurricane and Severe Storm Sentinel) Mission investigating why certain weather patterns become hurricanes, and why some hurricanes grow into monster storms.
