Do frogs get all high-voiced when they breathe in some helium, the way people do? A research study explores that very question, and we explore that study, in this week’s Improbable Research podcast.
This week, Marc Abrahams discusses a published helium-filled study, with dramatic readings from Dany Adams, a biology professor at Tufts University who uses electricity to make animals grow new limbs, and uses light to make cancer retreat in some animals.

The mysterious John Schedler or the shadowy Bruce Petschek perhaps did the sound engineering this week.
The Improbable Research podcast is all about research that makes people LAUGH, then THINK — real research, about anything and everything, from everywhere —research that may be good or bad, important or trivial, valuable or worthless. CBS distributes it, on the CBS Play.it web site, and on iTunes and Spotify).
