For a long time scientists have been trying to figure out what was been behind the extinction of the dinosaurs. Here is the latest theory - it's all about dust.

A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.
