Episode 5: Converging

Well, friends, this is our last episode for the summer, which is fine because everywhere EXCEPT Stanford is back to school right about now. If that’s you, maybe you can give this a listen to get your mind sharp before you ease back into things. We’re here talking about the computations that go on inside your eyeball to give you clear, reliable color vision!

This graph shows the spectrum of visible light and the differing sensitivities of your blue, green, and red cones (rods, too, for vision in dim light!).

In Converging, student host Anthony Agbay talks with Dr. Levi Gadye, whose expertise is in the stem cells that live in your nose. They discuss the retina, the ethics of animal research, genes, tumors, and more! For show and tell, Levi brings a study he encountered as a wee first-year graduate student. This is an impressionable and hopeful time for a scientist, and so we think it makes for a nice end to the summer, yes?

We’ll be back in the fall with more new episodes. If you’re a Stanford student and want to host an episode or a local scientist with a communicative streak, please get in touch!
