It's another Lost in Science Triple Creature Feature! Claire talks to Vincent Raoult from the University of Newcastle about using magnets to repel sharks and rays from fish traps. Stu tells us about the fungus Massospora cicadina, which uses psychedelics to hijack cicadas before replacing their abdomens (pictures at https://www.nature.com/articles/s41598-018-19813-0, but be warned, they're disgusting). And Chris explains how wolf spiders in the Arctic could be helping to fight warming by changing their diet.
