If you have arachnophobia, consider this your opportunity to try exposure therapy: A new study suggests that 415 million years ago, in modern-day England and Wales, a scorpion the length of a golden retriever was scurrying around, complete with 6-inch pincers. Flora talks with lead study author Richie Howard about the finding.

If you’re grossed out by a 3-foot scorpion, you’re not alone. But, scorpion researcher Lauren Esposito says we’ve got it all wrong—scorpions are wonderful and caring creatures.
