It’s that time of year again, where Harvard mammalogist and milk researcher Katie Hinde (who we met in Episode 56) pits mammals from across the world against one another to find out who will reign supreme! She gave Breaking Bio the scoop on who’s in and who’s out this year, along with some of the new rules and prizes!

This year’s brackets have just been announced, so go visit Katie’s blog (Mammals Suck), fill out your bracket, and join in the fun! The competition begins Monday, March 10th, so be sure to subscribe to Katie’s blog to catch the nightly matchups, and watch #2014MMM on Twitter for all the action!

Once you’ve made your picks, don’t be afraid to tag Breaking Bio and talk some smack. Who will be the maddest mammal of them all? Stay-tuned to find out!
