A Laser Built for Mars Has a New Gig: Authenticating Honey Slate

Scientists in England have found they can identify counterfeit honey using a laser originally built to explore the universe. Seven years ago at the Rutherford Appleton Laboratory in England, work began to build a laser that could identify isotopes in space. Specifically, the researchers wanted to get into the Martian atmosphere and investigate the Red Planet’s mysterious methane. Identifying carbon isotopic ratios, for instance, could set off a string of hyperbolic headlines here on Earth. As Dr. Damien Weidmann, Laser Spectroscopy Team Leader at RAL Space explained on their website, “If it’s bacterial in origin, it would mean a form of life occurred on Mars.”
