Transistor

Scents and tastes are powerfully evocative -- one whiff of perfume or cooking aromas can transport you back to a particular moment, a particular place, a particular person. Dr. Wendy Suzuki speaks with neuroscientist Howard Eichenbaum, an expert on olfactory memory, and together with chemist Kent Kirshenbaum, sits down to a meal with Chef Anita Lo to hear how she plays with our senses and our memories in her delicious creations.

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?

Looking through a telescope is like being inside a time machine -- you are seeing light from the past. And some space telescopes allow astronomers to see light that is billions of years old and existed before there was an Earth or sun. Astrophysicist Michelle Thaller introduces us to scientists who started two of the most powerful telescopes, the Hubble, which launched 25 years ago, and the James Webb Space Telescope, being built right now.

In the fall of 1902, twelve young men in suits regularly gathered for dinners in the basement of a government building in Washington, D.C. The men ate what they were served, even though they knew that their food was spiked with poison. The mastermind behind these experiments was Harvey Washington Wiley. Before you condemn him, though, you’d be surprised to know that you probably owe him a debt of gratitude. Incidentally, Wiley is the founding father of the Food and Drug Administration.

Many depictions of amnesia in TV, movies and even in cartoons are just plain wrong -- some laughably so. Host Dr. Wendy Suzuki talks with Prof. Neal Cohen, a Neuroscientist from the University of Illinois Urbana-Champaign. For 20 years, Neal has used bad examples of amnesia that abound as well as the rare accurate depictions as a powerful tool in his popular course about amnesia in pop culture. Neal entertains and educates with examples from Futurama, Memento, and 50 First Dates, and more, and we'll hear some of those clips.

Everybody knows about white noise -- that sound that comes out of your TV when it's not working quite right. But there are many other colors of noise, too: pink, brown, blue, and purple. Marnie Chesterton brings us this story on the colorful science of sound.

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 really 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?

Space scientists are acutely aware of what can happen when climates change in other parts of our solar system. Take Venus, where it rains sulfuric acid and is 900°F on the surface, but it wasn’t always that way. Astrophysicist Michelle Thaller talks with a NASA expert on Venus about how it became a hellscape. And she talks with the Library of Congress’ inaugural chair of astrobiology about how to grasp this new geologic era where humans cause rapid change.

Imagine remembering your childhood, your parents, the history you learned in school, but never being able to form a new long term memory after the age of 27. Welcome to the life of the famous amnesic patient “HM”. Neuroscientist Suzanne Corkin studied HM for almost half a century, and considered him a friend, even though he could never remember how he knew her. Suzanne gives us a glimpse of what daily life was like for him, and his tremendous contribution to our understanding of how our memories work.

In her episodes of Transistor, neuroscientist Wendy Suzuki introduces us to scientists who have uncovered some of the deepest secrets about how our brains make us who we are. She begins by talking with groundbreaking experimental psychologist Brenda Milner, who in the 1950s, completely changed our understanding of the parts of the brain important for forming new long-term memories.
