What? Me, a headache?


After my recent posts on the climate crisis, zoonotic disease, and the planet's loss of biodiversity, you'll likely welcome a lighter bit of news. I know I do!


An article in Scientific American caught my eye, partly because in an earlier life I did a small study of pileated woodpeckers. Those flying jackhammers, and their relatives, have continued to intrigue me.


The article explains why woodpeckers can hammer away thousands of times per day without addling their brains. And it's not because they have shock absorbers in their skulls!
