We all think we know the story of pregnancy. Sperm meets egg, followed by nine months of nurturing, nesting, and quiet incubation. this story isn’t the nursery rhyme we think it is. In a way, it’s a struggle, almost like a tiny war. And right on the front lines of that battle is another major player on the stage of pregnancy that not a single person on the planet would be here without. An entirely new organ: the placenta.In this episode, which we originally released in 2021, we take you on a journey through the 270-day life of this weird, squishy, gelatinous orb, and discover that it is so much more than an organ. It’s a foreign invader. A piece of meat. A friend and parent. And it’s perhaps the most essential piece in the survival of our kind.Special thanks to Diana Bianchi, Julia Katz, Sam Behjati, Celia Bardwell-Jones, Mathilde Cohen, Hannah Ingraham, Pip Lipkin, and Molly Fassler.EPISODE CREDITS: Reported by – Heather Radke and Becca Bresslerwith help from – Molly WebsterProduced by – Becca Bresslerwith help from – Pat Walters, Maria Paz GutierrezEPISODE CITATIONS:Articles:Check out Harvey’s latest paper published with Julia Katz.Sam Behjati's latest paper on the placenta as a "genetic dumping ground". Signup for our newsletter!!

The universe is put together like Swiss cheese – some regions are the cheese; others are the holes. The “cheese” consists of clusters and superclusters of galaxies. The “holes” are just that – cosmic voids. The largest voids span more than a billion light-years. Cosmic voids were discovered half a century ago. Astronomers were looking deep enough into the universe to map its structure on the largest scale. They’d expected the universe to look the same in all directions – a smooth blend of galaxies. Instead, they found a web – overlapping filaments of galaxies, with big spaces between. The voids might be there because there were tiny differences in the density of matter in the early universe – especially dark matter. The gravity in the denser regions pulled material together to make stars and galaxies. That left the less-dense regions almost empty. They contain a few galaxies, some gas and dust, and some dark matter, but not much else. More than 6,000 voids have been cataloged. They clump together to make supervoids. One of the closest is the Boštes Void – “the Great Nothing.” It’s centered about 700 million light-years away, and it spans more than 300 million light-years – a giant “hole” in the universe. Boštes climbs into view in early evening. Look for the bright yellow-orange star Arcturus, which is low in the east by 9 or 10 o’clock. The Great Nothing stretches to the upper left of Arcturus.
