Post No Evil
Back in 2008 Facebook began writing a document. It was a constitution of sorts, laying out what could and what couldn’t be posted on the site. Back then, the rules were simple, outlawing nudity and gore. Today, they’re anything but. How do you define hate speech? Where’s the line between a joke and an attack? How much butt is too much butt? Facebook has answered these questions. And from these answers they’ve written a rulebook that all 2.2 billion of us are expected to follow. Today, we explore that rulebook. We dive into its details and untangle its logic. All the while wondering what does this mean for the future of free speech? This episode was reported by Simon Adler with help from Tracie Hunte and was produced by Simon Adler with help from Bethel Habte. Special thanks to Sarah Roberts, Jeffrey Rosen, Carolyn Glanville, Ruchika Budhraja, Brian Dogan, Ellen Silver, James Mitchell, Guy Rosen, and our voice actor Michael Chernus.

The Bad Show
With all of the black-and-white moralizing in our world today, we decided to bring back an old show about the little bit of bad that's in all of us...and the little bit of really, really bad that's in some of us. Cruelty, violence, badness... in this episode we begin with a chilling statistic: 91% of men, and 84% of women, have fantasized about killing someone. We take a look at one particular fantasy lurking behind these numbers, and wonder what this shadow world might tell us about ourselves and our neighbors. Then, we reconsider what Stanley Milgram's famous experiment really revealed about human nature (it's both better and worse than we thought). Next, we meet a man who scrambles our notions of good and evil: chemist Fritz Haber, who won a Nobel Prize in 1918...around the same time officials in the US were calling him a war criminal. And we end with the story of a man who chased one of the most prolific serial killers in US history, then got a chance to ask him the question that had haunted him for years: why? This episode was produced with help from Carter Hodge. Support Radiolab today at Radiolab.org/donate.
Gonads: Sex Ed
If there’s one thing Gonads taught us, it’s just how complicated human reproduction is. All the things we thought we knew about biology and sex determination are up for debate in a way that feels both daunting and full of potential. At the same time, we're at a moment where we’re wrestling with how to approach conversations around sex, consent, and boundaries, at a time that may be more divisive than ever. So host Molly Webster thought: what if we took on sex ed, and tried to tackle questions from listeners, youth, reddit (oh boy), and staff. But instead of approaching these questions the way your high school health teacher might’ve (or government teacher, who knows), Molly invited a cast of storytellers, educators, artists, and comedians to grapple with sex ed in unexpected and thoughtful ways. To help us think about how we can change the conversation. In this episode, an edited down version of a Gonads Live show, Molly's team takes a crack at responding to the intimate questions you asked when you were younger but probably never got a straight answer to. Featuring: How Do You Talk About Condoms Without Condom Demonstrations? Sanford Johnson. Wanna see how to put on a sock? What Are Periods? Sindha Agha and Gul Agha. Check out Sindha's photography here. Is Anything Off-Limits? Ericka Hart, Dalia Mahgoub, and Jonathan Zimmerman Why Do We Do This Anyway? And Other Queries from Fifth Graders Jo Firestone "Sex Ed" is an edited* recording of a live event hosted by Radiolab at the Skirball Center in New York City on May 16, 2018. Radiolab Team Gonads is Molly Webster, Pat Walters, and Rachael Cusick, with Jad Abumrad. Live music, including the sex ed questions, and the Gonads theme song, were written, performed, and produced by Majel Connery and Alex Overington. One more thing!

Gonads: Dana
When Dana Zzyym applied for their first passport back in 2014, they were handed a pretty straightforward application. Name, place of birth, photo ID -- the usual. But one question on the application stopped Dana in their tracks: male or female? Dana, technically, wasn’t either. In this episode, we follow the story of Dana Zzyym, Navy veteran and activist, which starts long before they scribble the word "intersex” on their passport application. Along the way, we see what happens when our inner biological realities bump into the outside world, and the power of words to shape us. This episode is a companion piece to Gonads, Episode 4, Dutee. "Dana" was reported by Molly Webster, and co-produced with Jad Abumrad. It had production help from Rachael Cusick, and editing by Pat Walters. Wordplay categories were written, performed, and produced by Majel Connery and Alex Overington.

Gonads: X & Y
A lot of us understand biological sex with a pretty fateful underpinning: if you’re born with XX chromosomes, you’re female; if you’re born with XY chromosomes, you’re male. But it turns out, our relationship to the opposite sex is more complicated than we think. And if you caught this show on-air, and would like to listen to the full version of our Sex Ed Live Show, you can check it out here. This episode was reported by Molly Webster, and produced by Matt Kielty. With scoring, original composition and mixing by Matt Kielty and Alex Overington.

Annie would come to find out she had Stage 4 non-Hodgkin's lymphoma. It was so aggressive, there was a real chance she might die. Her oncologists wanted her to start treatment immediately. Like, end-of-the-week immediately. But before Annie started treatment, she walked out of the doctor’s office and crossed the street to see a fertility doctor doing an experimental procedure that sounded like science fiction: ovary freezing.

Birthstory
We originally posted this episode in 2015, and it inspired producer Molly Webster to take a deep dive into the wild and mysterious world of human reproduction. Starting next week, she’ll be taking over the Radiolab podcast feed for a month to present a series of mind-bending stories that make us rethink the ways we make more of us. You know the drill - all it takes is one sperm, one egg, and blammo - you got yourself a baby. Right? Well, in this episode, conception takes on a new form - it’s the sperm and the egg, plus: two wombs, four countries, and money. Lots of money. At first, this is the story of an Israeli couple, two guys, who go to another continent to get themselves a baby - three, in fact - by hiring surrogates to carry the children for them. As we follow them on their journey, an earth shaking revelation shifts our focus from them, to the surrogate mothers. Unfolding in real time, as countries around the world consider bans on surrogacy, this episode looks at a relationship that manages to feel deeply affecting, and deeply uncomfortable, all at the same time. Birthstory is a collaboration with the brilliant radio show and podcast Israel Story, created to tell stories for, and about, Israel. Go check ‘em out! Israel Story's five English-language seasons were produced in partnership with Tablet Magazine and we highly recommend you listen to all of their work at http://www.tabletmag.com/tag/israel-story This episode was produced and reported by Molly Webster. Special thanks go to: Israel Story, and their producers Maya Kosover, and Yochai Maital; reporters Nilanjana Bhowmick in India and Bhrikuti Rai in Nepal plus the International Reporting Project; Doron Mamet, Dr Nayana Patel, and Vicki Ferrara; with translation help from Aya Keefe, Karthik Ravindra, Turna Ray, Tom Wasserman, Pradeep Thapa, and Adhikaar, an organization in Ridgewood, Queens advocating for the Nepali-speaking community.

Audio Extra: Tal and Amir had a chance to meet each surrogate once - just after the deliveries, after all the paperwork was sorted out, and before any one left Nepal. As Amir says, they wanted to say "a big thank you." These meetings between intended parents, surrogate, and new babies are a traditional part of the surrogacy process in India and Nepal, and we heard reports from the surrogates that they also look forward to them. These moments do not stigmatize, reveal the identity of, or endanger the surrogates. Tal and Amir provided the audio for this web extra.
