  [Bonus] When a Last Resort Antibiotic Fails: The Drugs That Shape Us 17.09.2026 14мин

  On this bonus episode we answer a listener's question about antibiotic resistance arising from agriculture by diving into the story of colistin, an antibiotic that is used as a last resort treatment. When colistin resistance was first reported in animals and humans, the public health community was understandably panicked, prompting governments to take action to regulate its use.

  From Insulin to GLP-1s — a Peptide Saga: The Drugs That Shape Us, Episode 4 03.09.2026 41мин

  If you’re on social media, you may feel bombarded by influencers promoting peptides for a range of ailments so broad it almost seems like a brand-new trend. But peptide-based therapies actually date back to 1922, when insulin was first administered to treat diabetes. But it wasn’t until semaglutide (better known as Ozempic) entered the market that peptides truly captured public attention. In today’s episode, we explore how what chemists and other scientists learned from insulin paved the way ...

  Three Theories of Depression and the Promise of Psychedelics: The Drugs That Shape Us, Episode 3 27.08.2026 56мин

  In the late 1950s, a tuberculosis drug was repurposed as the world’s first antidepressant. Then the selective serotonin reuptake inhibitor (SSRI) Prozac ushered in a new era of antidepressants. Today SSRIs are some of the most widely prescribed drugs in the country, but gaps still exist in our biological understanding of mental health, the overall efficacy of antidepressants, and predicting serious side effects. In response, some scientists and physicians are turning to different classes of d...

  [Bonus] From the Cutting Room Floor: Anthrax Decontamination Following the 2001 Attacks 28.05.2026 7мин

  In the inaugural “From the Cutting Room Floor” — where we take parts of interviews that didn’t quite fit in our regular episodes — we talk about anthrax. Well not exactly… we talk about what happens with the chemicals that we use to kill anthrax. In 2001, some high profile people like news anchors and senators received mail laced with anthrax — a spore-forming bacteria that can be deadly. Afterwards, there were many spaces that had to be decontaminated. And Richard Corsi was tapped to study t...

  Does Earth Have Limits?: The Chemistry of Pollution, Episode 4 14.05.2026 29мин

  Pollution is only one way humans are altering our planet. There’s climate change, sea level rise, biodiversity loss, and much more. Earth system scientists, including biological oceanographer Katherine Richardson, developed the nine planetary boundaries, a framework to understand what Earth systems are critical for life, and what will happen if human-caused changes to our planet continue. Katherine unpacks these boundaries, revealing how chemistry sits at the heart of both the problems and so...
