Brigitta Green from the perennial winter wonderland of Minnesota has a fitting question for us about ice. After a mysterious, late night howling sound caused “mass slight curiosity” on the streets of St. Paul last winter, she wants to know how it is that a frozen body of water can produce such an eery noise. Chris Polashenski, Arctic researcher and expert on all things cold, has our answer.

What's the coolest or weirdest official name for a species of plant or animal? And how do they get those funny sounding Latin names anyway?

Is a watermelon a vegetable? Biologically it’s logical, but does the answer depend where you live?

Zookeeper Rick asks why why animals see color differently? Dr. Jay Neitz of the University of Washington Department of Ophthalmology says there is more than one factor that accounts for how animals perceive color. Some plants and animals present vibrant colors we can’t even see and for reasons they don't want us to know.

Listener Ross Wintle, driving past a cemetery near his home, wonders if animals other than humans have rituals around death? Barbara J King, professor emerita of anthropology at the College of William and Mary and the author of How Animals Grieve reports that when it comes to animals and death, you’ve gotta look at elephants. However there are also some interesting reports about magpies, red foxes and dolphins showing some interacting with the dead in their groups. Appropriately in a Day of the Dead episode, The Completely Optional Knowledge podcast helps us understanding that death is a bit more universal experience in the animal kingdom than just to humans.

Listener Matthew Hollingshead, a skateboard enthusiast, asks why it’s so funny to watch people get hurt. We’re not necessarily talking about critical injuries, more like America’s Funniest Home Videos style failures, pain, and embarrassment. Caleb Warren, an Assistant Professor of Marketing at the University of Arizona helps us answer this question and feel a little better about finding joy in other people’s “hilarious misery”.

Listening to Shohini Ghose talk about what would happen if a human reached light speed in Episode 16, Fred Papon of Australia wanted to know more about her research into quantum teleportation. Ghose reveals that teleportation has already happened, but don’t expect someone on the train with you to disappear after saying “Beam me up Scotty.”

Dallas College professor Patrick Moore, seeing his dog Abbey eating her own poo and swallowing dirty socks, wonders how animal tastebuds work. Danielle Reed, associate director of the Monell Chemical Senses Center, takes a break from feeding her cat Diet Coke to talk about the chemical properties of taste. Both cheese and sweaty socks smell like isovaleric acid. Dogs being omnivores unconstrained by the social cues that govern human behavior are going to go ahead and see if that sock is food. Host Andrew Norton would rather have listeners thinking about Mac and Cheese but he has his own taste issues. Maybe it’s in genetics?
