Why Do We Celebrate Groundhog Day?

On this week's show, Victoria kicks things off with a discussion of Chirality and how the study of the "handedness" of molecules could actually lead to the creation of completely new forms of life. It's a bizarre thought experiment with very real and dangerous consequences.

Rachel brings us a creature feature, the fish-scaled gecko. This strange creature has an amazing defense mechanism that is both fascinating and gross.

Kirk ends things with a salute to Groundhog Day and he dives into the possible science behind why we think these giant ground squirrels can predict the weather.
