Restoring land after dam removal, and phonons as a basis for quantum computing 

First up on this week’s show, planting in the silty soil left behind after a dam is removed and reservoirs recede. Contributing Correspondent Warren Cornwall joins host Sarah Crespi to talk about the world's largest dam removal project and what ecologists are doing to revegetate 36 kilometers of new river edge.

Next up on the show, freelance producer and former guest Tanya Roussy. She talks with Andrew Cleland, a professor at the University of Chicago, about a Science paper from this summer on using the phonon—a quantum of sound energy—as the basis of quantum computers.

This week’s episode was produced with help from Podigy.
