This Week I Learned

Ep. 72: This week I learned plants can smell predators coming, and more

Episode Summary

Plants can smell | Bacteria can feel | It snows sunscreen on a planet far, far away | The purpose of those silly little T. Rex arms

Episode Notes

This week I learned plants can sniff out their predators, bacteria have a sense of touch, there's a planet in another solar system where it snows sunscreen, and there might be a very good reason why the T. Rex had those comically short arms.
