What does it mean to be alive? Our origins are the horizon of our understanding, and as with the physical horizon, our approach brings us no closer. The more we learn, the more mysterious it all becomes. What if we’re asking the wrong questions? Maybe life did not begin at all, but rather coalesced piecemeal, a set of properties contingent and convergent, plural, more than once? Maybe the origin of life is happening right now, just over the horizon, forming something new anew. Let’s get into the weeds and see if we can find a continuity between biology and physics.

Welcome to COMPLEXITY, the official podcast of the Santa Fe Institute. I’m your host, Michael Garfield, and every other week we’ll bring you with us for far-ranging conversations with our worldwide network of rigorous researchers developing new frameworks to explain the deepest mysteries of the universe.

This week we speak with Kate Adamala, synthetic biologist and professor at the University of Minnesota, about her research to produce synthetic minimal cells that are not technically alive but can perform myriad biological processes. Along the way the distant past and future meet. Can we build life? Or can we grow machines?
