SETI, Aliens and the Origins of Life

How do we look for life beyond Earth?  And how did it first get started down here?  To help us take on these big questions, we explore the science of SETI and the chemistry of creating life.  Plus, science gets cinematic as we meet the scientific adviser for Prometheus, and find out how his work could help us understand alien atmospheres.  In the news, how to sequence a baby using just the mother's blood, and the simple intervention that could prevent millions of malaria cases.  In Question of the Week, can we create life in the lab from just elements and heat?

    What is intelligent life?

  • 50:37 - Were Miller's results right- or left-handed??

    We know that the amino acids we use on Earth are all left handed. How about the molecules found in Stanley Millerís experiments? Were they of an even distribution of right and left handed forms or was there a bias?

  • 52:03 - What technology could help find alien life?

    What potential technologies for communication are out there that we are NOT using. Obviously there are optical and radio telescopes. Is there anything else we could try?

  • 54:52 - Can we create a living organism from basic elements?

    Hi Chris and other scientists. I listen to your podcast weekly. Love them. Has there been any progress in creating a living organism from basic elements (CHONPS) and some heat? Seems like with so many advances in human biology, science should be able to produce a simple organism...
