The world's longest treasure hunt
After 31 years, a mammoth treasure hunt consisting of solving eleven cryptic clues has finally concluded. A replica of the final prize \u2013 a golden owl \u2013 was dug up in France, leaving fellow treasure hunters both disappointed and relieved.
Inspired by this pursuit, the Unexpected Elements team unearth some of science\u2019s hidden gems. From the potential resurrection of ancient healing tree balm to the world\u2019s rarest stone, and even how cats could help solve crimes. The team are also joined by astrobiologist Nathalie Cabrol to speak about the potential treasures hiding on another moon in our solar system. Along the way, our panel have their own clues to crack as they take on a mini hunt of their own to find the location of a scientific golden nugget.
Plus, we solve the mystery of a moth which ended up 4000 miles from home, hear what our brains see when we can\u2019t and talk about returning treasures to where they came from.
