This week, in addition to listening to the winds of Titan, we will train our ears on the winds of change here on Earth. The first human-animal chimeras have emerged in laboratories around the world and with them a new debate in bioethics. Biology continues to merge with silicon-based technology. And if you think science fiction becoming science fact is unsettlingly, then you may not want to listen to my commentary on transhumanism and rumors of current life on Mars.
