This week Rachel kicks things off with a story about the amazingly fast growing invasive Japanese Knotweed. Our guest, Marika Bell then takes a fascinating look at how different animals perceive colors. Finally, Kirk rounds out the show describing a bizarre prehistoric fish that could cut you in half in less than the blink of an eye! We're all over the board this week and we couldn't be happier about it.
