This week, in honor of Halloween, we're presenting two classic stories about facing fears for science.

Part 1: As a newly minted PhD student in geology, Erik Klemetti starts to question his decisions when Aucanquilcha, a 20,000-foot volcano in Chile, proves difficult to tame.

Part 2: Explorer George Kourounis finds himself growing increasingly anxious as he prepares to enter a fiery sinkhole known as the “Doorway to Hell.”

Erik Klemetti is an associate professor of Geosciences and volcanologist at Denison University. He works on volcanoes all over the planet, from Chile to New Zealand to the Cascades of Oregon and California. His research focuses on how crystals record the events inside a volcano before and between eruptions. For the past 9 years, he’s been teaching all the “hard rock” classes at Denison. He also writes for Discover Magazine. His blog, Rocky Planet, have been running since Fall 2017. Before that, he wrote Eruptions, a blog about volcanoes, for Wired Science for 9 years. You can also find him on Twitter (@eruptionsblog), variously tweeting about volcanoes, baseball (mostly Red Sox and Mariners) and his love of punk.

George Kourounis is a renowned global explorer and storm chaser who specializes in documenting extreme forces of nature including: tornadoes, hurricanes, volcanoes, deserts, caves, avalanches and more. He is an Explorer In Residence for The Royal Canadian Geographical Society, served as the Chairman of the Explorers Club Canadian Chapter, and has received several awards and medals for his efforts. He frequently finds himself driving into the eye of fierce storms, or descending ropes into actively erupting volcanic craters, often while hosting television programs including “Angry Planet” and others. He has given five TEDx talks, and has addressed the United Nations Environmental Emergencies Forum. George’s expeditions have taken him to over 80 countries on all seven continents to such far-flung places as: Madagascar, Turkmenistan, Vanuatu, Greenland, North Korea, Myanmar, and Antarctica.

In this week’s episode, both of our storytellers learn the hard way that getting high doesn’t always mean having a good time.

Part 1: At his friend’s bachelor party, Andrew McGill joins in on a mushroom trip that quickly spirals out of control.

Part 2: In an attempt to calm his nerves about going on an Alaskan cruise, Will Clegg turns to marijuana.

Andrew McGill is a storyteller born and raised in Brooklyn, NY when not on stage is a English teacher at a high school in Brooklyn.

Will Clegg is a filmmaker, storyteller, and new dad living in Westfield, NJ. He’s the co-creator and sometimes host of the long-running storytelling show “Awkward Teenage Years” as well as the writer and performer of two solo shows: “The Lonely Road” and “Syncope.”

In honor of OCD Awareness Week, this episode features two deeply personal stories about living with obsessive compulsive disorder.

Part 1: For Hannah Hedelius, a classmate’s hiccups trigger an overwhelming reaction she can’t hold back.

Part 2: As a graduate student, Rachel Hostetler begins to realize that her intrusive thoughts may be more than just regular stress.

Hannah Hedelius was born and raised in Idaho. She received her Bachelors of Psychology from Boise State University and is currently working on her Masters in Biomolecular Sciences. Hannah plans to attend medical school where she will work towards a dual doctorate for a career as a medical scientist. Hannah is a graduate assistant for the Dean of Students Office where she works in substance misuse prevention. She focuses on creating alcohol and other drugs education and awareness. Hannah is also doing research at Boise State where she studies cholera toxin and its potential in treatment of inflammatory bowel diseases. In her free time, Hannah enjoys reading and spending time with her family.

Rachel Hostetler is a scientist at the Allen Institute for Brain Science and her role focuses on providing scientific training to users of the institute’s tools and datasets. Prior to working at the institute, she completed a Ph.D. in Neuroscience at West Virginia University, where she used many Allen Institute datasets to guide her research on somatostatin inhibitory interneuron diversity. She completed her B.S. at the University of Minnesota, double-majoring in Neuroscience and German Studies. Now living in Seattle, she yells out in excitement whenever she sees a mountain (not just Mt. Rainier but literally any mountain) after growing up in the Midwest. When not yelling at mountains, she spends her free time trying new seafood restaurants with her partner, snuggling with their very needy cat, and exploring the beauty of the PNW.
