How Fleas Work

Fleas are the bane of the existence of pet owners. From their eggs to their lifespan to their feeding habits, fleas are practically designed to be a nuisance. They are parasites, after all. Get down on flea level with Josh and Chuck in this episode.

The Best Stuff We've Read This Week

Each week, Chuck and Josh read tons of articles. Here are the best of the bunch. Enjoy them with our compliments.

The Black Death is now (Likely) Extinct (Perhaps)

You may now breathe a small sigh of relief; if you are the type to believe what you read in studies from the University of Tübingen, at least: The bacteria thought to be behind the Black Death plague that killed 50 million people in Europe and Asia in about five years in the middle of the 14th century is thought to now be extinct. Oh, there are related versions of the bacteria, Yersinia pestis, alive and well today. As many as 2,000 people die from it around the world each year. But the particularly virulent form that swept across the East like a black death, that one is probably no longer around.
