Naked and Afraid: Last One Standing Survivalist's Weekly PSR Ratings

Let’s say one day astronomers announce that our worst nightmare has come true: a large object is headed towards the Earth with a significant chance of impact. What do we do?

National Insect week occurs between June 20 -26. The week focuses on the importance of insects within ecosystems, nature, and wildlife. Insects do have a bad reputation, as some are a nuisance, and some are scary, but each plays a key role in maintaining order in nature. In celebration of the hard-working insects that you may see in your backyard, here’s a list of the ones you won’t be seeing. The rarest insects on the planet.

Host Luke Tipple is joined this week by renowned Harvard professor, Dr. Avi Loeb, who recently led a deep-sea expedition to discover if evidence for advanced alien life crash-landed off the coast of Papua New Guinea in 2014. They discuss the recent Congressional UFO hearings, how the last seventy years of research into extraterrestrial life has been potentially misguided, and the challenges of searching for tiny objects on the bottom of the ocean.

Shark Week’s Luke Tipple tackles the question “How can I work with sharks?” alongside two experts in the field – and their answers are not always the obvious ones. Luke is joined first by Kelly Link, Associate Curator of the Georgia Aquarium who talks about what it’s like to be an aquarist, how it differs from field work, and how to get yourself noticed. The second guest is Dr. Neil Hammerschlag who goes into detail on what it takes to become a prominent scientist, and what other paths you can take if a PhD isn’t for you. And at the end, researcher Sierra stops by to tell us about the world’s smallest shark.
