• Fluoride: Is Your Water Safe?

  The battle over whether we should be putting fluoride in our water has reached fever pitch. We’ve got U.S. Health Secretary Robert F. Kennedy Jr. and anti-fluoride activists saying it’s a neurotoxin that’s lowering our IQs. But supporters say that fluoride is a safe and effective way to protect our teeth from cavities, and that stopping water fluoridation would lead to a spike in tooth decay. To find out who’s right, we talk to epidemiologist Dr. Ashley Malin and community health scientist Professor Lindsay McLaren.  Find our transcript here: https://bit.ly/ScienceVsFluoride  In this episode, we cover: (00:00) Chapter 1: Why did we start water fluoridation?  (07:00) Chapter 2: What can fluoride do at really high levels?  (11:18) Chapter 3: Can low doses of fluoride affect the brain?  (20:41) Chapter 4: Anything else to worry about? (24:53) Chapter 5: Does fluoride in the water protect our teeth? This episode was produced by Meryl Horn, with help from Wendy Zukerman, Rose Rimler, Michelle Dang, and Ekedi Fausther-Keeys.

• Squirting: What's Really Happening?!

  [Video available on Spotify] To start off the new season we’re getting into the science of one of the most controversial and taboo sex topics around. Squirting! For some people, it’s a major sex goal — but for others, it’s a source of major embarrassment. And it turns out that people have been writing or talking about squirting and female ejaculation for CENTURIES. So in this episode, we’re going to find out: what IS squirting (like, what is this fluid??), how common is it, and if you want to start doing it … how can you? We’ll hear from Sex Educator and World Record Holder, Lola Jean. As well as Professor Caroline Pukall, Dr. Nan Wise, Professor Helen O’Connell, and Dr. Samuel Salama.  UPDATE, April 4, 2025: An earlier version of this episode mistakenly said that usually a person cannot pee with an erect penis. While it can be difficult, it is possible (as anyone who's had a morning glory will know!). The episode has been updated. Find our transcript here: bit.ly/4iIVQcc In this episode, we cover: (00:00) Welcome to Cirque du Squirt (08:26) History of female ejaculation (13:18) Suspect 1: Vaginal lubrication (15:55) Suspect 2: Pee (24:41) Suspect 3: Chemical X?
