The Answer

PacSci-Doku: "Ancient Mystery" AnswerThe question in this edition is:

What substance recently uncovered a mystery at Stonehenge?

The answer: Strontium

The analysis of strontium in the skeletons of 25 individuals buried near Stonehenge shows that ten of them likely came from Wales 140 miles away. That doesn’t seem far today, but it was in 3,000 BC when Stonehenge was built. The strontium in the skeletons can be mapped to the level of the element found in different locations in the Britain, and the level of strontium is close to that found in Wales. The blue hue of the rocks making up Stonehenge suggest they came from Wales, so it now appears some of the workers who built Stonehenge probably did also.
