In her episodes of Transistor, biologist Christina Agapakis is exploring the microbiome: the trillions of bacteria, fungi, and viruses that live in and on our body. She starts with food. Bacteria-rich foods such as tempeh, cheese, pickles and yogurt have long been praised for their probiotic effect. But can you really add enough good bacteria to your digestive system to outnumber the bad?
It still seems hard to believe, but for one disease, poop -- yes, human poop -- is nothing short a miracle cure. Microbiologist Christina Agapakis takes a look at Fecal Microbiota Transplants or FMT and what happens when you take the really complex gut microbiome from a healthy person and transplant it into the gut of a sick person. For patients suffering from a one of the most common and deadly hospital acquired infections, Clostridium Difficile, or C Diff, one poop transplant can cure them, sometimes within hours. But, why?
One of the things we assign to science is that there are true, absolute facts. But scientists are human and, it turns out, as prone to blind spots in their thinking as the rest of us, especially when cultural assumptions and biases get in the way. Biologist Christina Agapakis explores ways these blind spots, especially around gender and sexism, have affected research and women’s careers in science. She talks with one of her heroes, anthropologist Emily Martin, and Emily's husband, biophysicist Richard Cone, about Emily's 1991 article "The Egg & The Sperm." She also talks with anthropologist Kate Clancy, who has spent a lot of time thinking and writing about the ways women’s careers in science are different from men’s.
Your skin is your largest organ and is also is a thriving ecosystem, covered in bacteria. While many of us consider regular showers key to keeping our skin healthy, a group of scientists -- and artists -- are starting to ask: Could the future of skin care not be soap, but bacteria?
