  1. Flemmie Kittrell and the Preschool Experiment

    Flemmie Kittrell and the Preschool Experiment

    Alexis Pedrick joins Katie Hafner to bring you an episode from The Lost Women of Science Initiative, a non-profit educational organization dedicated to telling the forgotten or untold stories of remarkable female scientists and their groundbreaking work through history.  The episode, which originally aired in October 2023, is about Flemmie Kittrell, the first Black woman to earn a PhD in Home Economics. In the early 1960s, Flemmie decided to see what would happen if you gave poor kids a boost early in life, in the form of a really great preschool. Every day for two years, parents would get free childcare, and their kids would get comprehensive care for body and mind—with plenty of nutritious food, fun activities, and hugs. What kind of difference would that make? And would it matter later on?

  2. The CRISPR Babies

    The CRISPR Babies

    In 2018 news broke that a Chinese scientist, He Jiankui, had used CRISPR to edit human embryos, and twin girls had been born as a result. The story set off an explosive bioethical controversy. As gene editing expert Kiran Musunuru put it, "He Jiankui's genetic misadventures were the biggest medical story of the century so far." Both scientists and the public had a lot of questions. What was the unmet medical need that justified the gene editing? Was the science ready for prime time? And, if it was, was He Jiankui the right scientist to do it? Seven years later these questions are far from resolved.

    Humans and Monsters: An Interview with Surekha Davies

    The fears about genetic engineering were stoked when experiments took off in the 1970s. From lab leaks to disease epidemics to the ability to make "Frankenstein creations," many of those fears are still with us today. We talk to author Surekha Davies about her latest book, why she thinks of monsters as category breakers and why blurring boundaries can be so terrifying for us, but maybe doesn't have to be.

She tells us about the history of IVF, from the first known artificial insemination by donor produced in Philadelphia in the 19th century to the scientific race in the 1960s and 1970s that resulted in the first so-called "test-tube baby."

  5. Gene Therapy's Families

    Gene Therapy's Families

    When Rebekah and Evan Lockard's daughter, Naomi, was diagnosed with a devastating ultra-rare genetic disease, they didn't know where to turn. Then they found Terry Pirovolakis, an IT professional who had made a gene therapy for his son with the same disease. But the process of getting Naomi treated has been an uphill battle, full of financial and logistical obstacles. The Lockard's story flips the question we've been asking all season on its head. Instead of wondering, "if we could do something, should we," we're now asking, "if we can do something that helps patients, should we do it at any cost?" And this question isn't for scientists or researchers, it's for the rest of us.

  6. Gene Therapy's Dark Ages

    AUG 19

    Gene Therapy's Dark Ages

    Gene therapy is based on a simple-sounding, yet deceptively complicated premise: adding or replacing faulty genes to fix medical problems. A compelling idea that came out of breakthroughs in DNA research, the field grew lightning fast. But the death of teenager Jesse Gelsinger after a gene therapy clinical trial left the public and scientists questioning the field's promise.  Why did researchers push ahead with clinical trials despite gene therapy still being  in its infancy? What does the Jesse Gelsinger story tell us about the personal risk behind medical breakthroughs?

    The People vs. Recombinant DNA

    In 1976, Harvard University wanted to build a specialized lab for recombinant DNA research. But first, it had to get permission from the city of Cambridge. The resulting city council hearings drew TV stations and captured the attention of the whole country. At the center of the controversy? A wise-talking mayor, a young outspoken molecular biologist, and an important question: in scientific research, how much say should the public have?
