Iowa Derecho, Showering And Hygiene, Parasites. August 21, 2020, Part 2

Dealing With The Aftermath Of Iowa’s Devastating Derecho  It’s been more than a week since the state of Iowa was hit by a surprise visitor: a line of thunderstorms with unusual power and duration, known as a derecho. The storms swept from South Dakota to Ohio in the course of a day. At its most powerful, the derecho hit Iowa’s Linn County and surroundings with hurricane-force winds amid the rain. Crops like corn and soybeans were flattened, while thousands of homes were damaged—if not completely destroyed.  Ira talks to Iowa Public Radio reporter Kate Payne and University of Northern Iowa meteorology professor Alan Czarnetzki about the devastating effects and unpredictable power of last week’s storm. An Argument For The Benefits Of—Not Bathing COVID has us all taking personal hygiene a lot more seriously these days. But for some, staying home during the pandemic has them rethinking their hygiene routines, including not showering. If the idea of not showering every day makes you feel icky, how about not showering for years? Writer James Hamblin says he stopped showering five years ago and never looked back. He says his skin has never been better, thanks to his healthy, well-functioning skin microbiome.  In his new book Clean: The New Science of Skin, Hamblin challenges the conventional wisdom about staying clean, and digs into the history of why we started showering in the first place. He discovered our modern notions of cleanliness have more to do with marketing and advertising than what’s really good for your skin. Hamblin joins Ira to talk about breaking the rules when it comes to cleanliness and discovering the benefits of skipping that shower.  Should We Conserve Parasites? Some Scientists Say Yes The idea of a parasite—an organism that needs a host organism—has always captured our attention and has been the theme of countless movies, from the sci-fi horror film Alien to the Oscar-winning movie Parasite. But a group of scientists say that parasites undeservedly get a bad reputation, and that some of them should even be conserved. They published their 12-point parasite conservation plan in the journal Biological Conservation. Parasite ecologist Skylar Hopkins and museum curator Kayce Bell, who are both authors on the recent article, talk about the role of parasites in the ecosystem and how a conservation plan might work.  Subscribe to this podcast.
