This episode of the Voices from DARPA podcast takes listeners on a tour of an audacious, decade-long project to merge biology and engineering into one of the most powerful engines of molecular invention the world has known. Although plenty of work remains to be done, the program, Living Foundries, is winding down to a close. But not before its community of research performers and collaborators already has delivered a new and versatile biotechnology platform whose consequences have begun to ripple out. New companies. Follow-on investments. Chemical- and materials-based technologies for the Department of Defense … and perhaps one day for the public at large. Featured in the podcast are reflections form three of the program managers who have been stewards of the program, two research performers who helped make real the vision of Living Foundries, and even the sound of one potential Living Foundries product doing what it does best.
