I had the pleasure of chatting with Maggie Koerth-Baker again for Bloggingheads Science Saturday, this time talking about the future of energy, how biotechnology might play a role in that future, and the risks involved in new technologies as well as the risks of sticking to old ones. Biosafety and risk assessment are huge and complex issues (and have been in the news recently) and we were only able to scratch the surface here so I hope that we can keep this discussion going!
