A science series from PRX.

Transistor is a transformative STEM podcast from PRX. Three scientist hosts — a biologist, an astrophysicist, and a neuroscientist — report on conundrums, curiosities, and current events in and beyond their fields. Sprinkled among their episodes are the winners of the STEM Story Project, a competition we held for unique science radio.

Much as the transistor radio was a new technical leap, this Transistor features new women voices and sounds from new science producers.

PRX presents Transistor, applying our storytelling and podcast experience to science. The Sloan Foundation powers Transistor with funding and support.

Transistor is supported by the Alfred P. Sloan foundation, enhancing public understanding of science, technology, and economic performance. Learn more at
