Last May, two research groups announced a breakthrough: they each grew human embryos, in the lab, longer than ever before. In doing so, they witnessed a period of human development no one had ever seen. But in the process, they crashed up against something called the '14-day rule,' a guideline set over 30 years ago that dictates what we do, and possibly how we feel, about human embryos in the lab. On this episode, join producer Molly Webster as she peers down at our very own origins, and wonders: what do we do now? This piece was produced by Molly Webster and Annie McEwen, with help from Matt Kielty. Special thanks goes to the Bioethics Research Library at Georgetown University; Omar Sultan Haque, Kevin Fitzgerald, SJ, and Josephine Johnston; Charlie McCarthy; Elizabeth Lockett, Mark Hill, and Robert Cork; plus, Eric Boodman, Lauren Morello, and Martin Pera. Producer's note about the image: Check out the super cool picture that's running with this piece. Scientist Gist Croft sent it to me a couple of weeks after my visit to the Rockefeller lab: it’s an image of the very embryo I looked at under the microscope - a twelve-day old human embryo - but with all the detail highlighted using fluorescent dye. (When I looked in person, we were using a light microscope that showed everything in black and white, with not nearly that precision.) The neon green bits are what's called the epiblast, the clump of cells from which the entire human body develops. See how it looks like it's pulling apart in to two? The scientists don’t know for sure, but they think this embryo might have been on it's way to becoming TWO embryos. Twinning! In action!

An update on Ross McNutt and his superpower — he can zoom in on everyday life, then rewind and fast-forward to solve crimes in a shutter-flash. But should he? In 2004, when casualties in Iraq were rising due to roadside bombs, Ross McNutt and his team came up with an idea. With a small plane and a 44 mega-pixel camera, they figured out how to watch an entire city all at once, all day long. Whenever a bomb detonated, they could zoom onto that spot and then, because this eye in the sky had been there all along, they could scroll back in time and see - literally see - who planted it. After the war, Ross McNutt retired from the Air Force, and brought this technology back home with him. Manoush Zomorodi and Alex Goldmark from the podcast “Note to Self” give us the lowdown on Ross’s unique brand of persistent surveillance, from Juarez, Mexico to Dayton, Ohio. Then, once we realize what we can do, we wonder whether we should.

In today’s episode, we meet a young woman from Texas, born and raised, who can’t prove that she exists. Alecia Faith Pennington was born at home, homeschooled, and never visited a dentist or a hospital. By both chance and design she is completely invisible in the eyes of the state. We follow Faith as she struggles to free herself from one restrictive world only to find that she is trapped in another. In her journey to prove her American citizenship she attempts to answer the age-old question: who am I? Reported and produced by Alexandra Leigh Young. Produced by Andy Mills and Brenna Farrell. Special thanks to Savannah Escobar, Nick Reed, Chris Van Deusen, David Glenn, Zen Allegra, Russell Whelan, Rachel Coleman and Lake Travis Zipline Adventures. Correction: An earlier version of this episode's web copy incorrectly stated that Faith Pennington was born on a farm. Pennington was born at home in Houston, TX, then she and her family moved to a farm in Kerrville, TX, where she was raised.  Faith’s original Youtube video is posted here: https://www.youtube.com/watch?v=CPtpKNyaO0U For updates on Faith’s journey, visit her Facebook page Help Me Prove It: https://www.facebook.com/Help-Me-Prove-It-882732628415890/ Support Radiolab by becoming a member today at Radiolab.org/donate.
