As part of Doug Emlen’s biology lab at the University of Montana in Missoula, Jillian del Sol was no stranger to bug battles. Year after year, study after study, species after species, students in Emlen’s lab have revealed the dramatic effects of sexual selection on male biological weaponry. So when she travel to East Asia to witness the tree trunk battles of the rhino beetles as part of her Ph.D. research, she came prepared to document the ecological conditions that influence chitinous combat. To her surprise, the successful male beetles didn’t just claim their prize after ousting their foes. Instead, they began to sing- or rather chirp and chitter at the females. This acoustic courtship continued even as they mated. Clearly, there was more to this mating system than just an escalating arms race between males. Now equipped with 150 beetles from field sites from Japan, del Sol aims to record these acoustic mating rituals in detail to hopefully discover why this bruiser bug suddenly turns from fighter to lover.

In a basement laboratory at the University of Pennsylvania, two roboticists have harnessed the innate sensing, swimming, and swarming abilities of bacteria to power microscopic robots. Even though their work sounds like the prologue to a dark science fiction film, Ph.D. students Elizabeth Beattie and Denise Wong hope these initial experiments with nano bio-robots will provide a platform for future medical and micro-engineering endeavors.

Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn’t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we’re going to take a look a couple modern computing problems like sorting and graph search, and show how we’ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell... or like a restaurant or something.

Ps. Have you had the chance to play the Grace Hopper game we made in episode 12. Check it out here! http://thoughtcafe.ca/hopper/

What high-tech materials are required to make a robotic hand that can pick up almost anything? Coffee grounds and a latex balloon. The design comes from a team of researchers including Heinrich Jaeger of The University of Chicago and John Amend, who is now trying to sell these grippers through Empire Robotics. But you can make your own version at home with some simple materials. The only tricky-to-find object you'll need is a vacuum pump (I got mine from here: https://www.sparkfun.com/products/10398, where you can also find an excellent instructional video).

By studying tiger and cat tongues, Alexis Noel of Georgia Institute of Technology has discovered some surprising uses for their infamously raspy licking apparatuses. Noel research has demonstrated that not only do their tongues tenderize meat, but the conical and scoop-like form of their papillae are optimized for depositing allergen infused saliva baths. So basically every time you pet your cat you are just rubbing your hand over their evenly-distributed saliva.

As the Roman Empire fell, so did the theater. If there's anyone who hates theater and actors more than Romans, it's early Christians. As Christianity ascended in the west, theater declined. But, fear not. This isn't the end of the series. Theater would be back, and in the best subversive theater-y fashion, it would return via the Catholic mass!
