In cancer research, the “seed and soil” hypothesis posits that the tumor is like a seed of misbehaving cells taking root in the body. Whether it grows—and where it grows—depends on the conditions, or soil. Since this hypothesis was proposed more than 100 years ago, most research and treatments have focused on the seed, or tumor. For nearly 50 years, Rakesh Jain has been studying the soil. But in a seed-focused field, his work was seen as wasteful and radical. Now, that very same research has led to seven FDA-approved treatments for diseases including lung and liver cancer, and earned him a National Medal of Science in 2016. Host Flora Lichtman talks with Jain about how his fringe idea led to lifesaving cancer treatments. Guest: Dr. Rakesh K. Jain studies the biology of tumors at Harvard Medical School and Massachusetts General Hospital as a professor of radiation oncology.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

For many people, bubonic plague is an illness that seems squarely situated in medieval times. But each year, a handful of human cases pop up in the western United States. Plague can be treated successfully with modern medicine. But why does it still exist, and how should we think about it both locally and globally? Plague researcher Viveka Vadyvaloo joins Host Flora Lichtman to talk all things spread and containment.Guest: Dr. Viveka Vadyvaloo is a plague researcher and director of the Allen School for Global Health at Washington State University.Transcripts for each episode are available within 1-3 days at sciencefriday.com.  Subscribe to this podcast.

Today we’re spotlighting an underappreciated group of marine creatures: sea slugs. Don’t let their humble name fool you. They come in vivid neon colors, with patterns that rival the most beautiful butterflies and feather-like external gills and tentacles.There are an estimated 10,000 species of sea slugs and they are incredibly diverse. Some are smaller than a quarter. And one species can weigh more than a terrier, up to 30 pounds. Not to mention their contributions to brain research—understanding their neural networks was the basis for a Nobel Prize in 2000.  Marine biologist Patrick Krug joins Host Ira Flatow to dive into the slimy science of sea slugs. Guest: Dr. Patrick Krug is a sea slug researcher and professor of biological sciences at Cal State LA.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
