Antler tissue is the fastest growing animal tissue on the planet. It grows faster than a human embryo, faster even than a cluster of cancer cells. On a hot summer day, some antlers can grow as much as one inch per day! And buried inside them is a cocktail of nutrients that both animals and humans are itching to get their paws on. In summary: Antlers are freaking amazing. So in this episode of Outside/In, we’ve invented a new segment just to highlight them. We’re calling it Holy Scat! and it’s our way of exploring all the things about the natural world that make us totally geek out. For our inaugural adventure, we learn about how antlers grow so fast, meet a collector who covers hundreds of miles searching for them, AND find out why scientists hope antlers could unlock new treatments for osteoporosis. Plus, we’ll tell you a whole herd of awesome deer factoids, and answer the eternal question: are Santa’s reindeer males or females?  Featuring Henry Ahern, Will Staats, Brendan Lee, and Tomas Landete-Castillejos.
