Jamelle Bouie explains to Sarah what the Reconstruction era was, why it remains relevant today, and how this history lesson is one that could get some high school teachers into legal trouble due to passage of anti-CRT laws.
S2 Ep 24. The world’s most efficient swimmer is the moon jellyfish! It’s the inspiration for a soft underwater robot that is safe enough to use in fragile environments like coral reefs and aquatic archaeological sites. By contracting a ring of muscle, the jellyfish can push water out of their bell-shaped bodies, thrusting them forwards without using much energy at all.

Masks, you may not have worn them before 2020 but now we?re all at it. With the rise of the Omicron variant countries have scrambled to reintroduce public health policies, among them mask wearing. Health officials and scientists agree that masks help reduce the incidence of covid19 infections ? but by how much is still debated. Several newspapers recently reported that masks could cut Covid-19 infections by 53%, we look at how they came to this number and whether we should be believe it.
Banning books from classrooms and school libraries is nothing new, but it's recently become a topic of considerable political debate. How should parents react to this news, and to the books their children are reading?
In this episode of NPR's It's Been A Minute senior editor Barrie Hardymon and Traci Thomas, host of The Stacks podcast, joined guest host Ayesha Rascoe to talk about banned book lists.The three talk about why it's important for kids to discover books freely, even if that means starting a hard conversation with them. They also discuss their favorite — and least favorite — books that often show up on banned book lists.
The Lightning Network is arguably the most anticipated scaling solution for Bitcoin to date. Why isn’t everyone using it?
“Speaking of Bitcoin” hosts Adam B. Levine, Andreas M. Antonopoulos and Stephanie Murphy are joined by Rene Pickhardt, Bitcoin and Lightning Network Developer. The four lead a conversation on the still in development yet rapidly growing Lightning Network. It's a second-layer network that enables fast, secure, private and inexpensive payments that don't make sense to store on bitcoin's base layer. But while that might sound ideal, it's not simple in practice. A scrappy community of companies and developers have been pushing the tech consistently forward as the number of hard problems still to solve ticks down.
Even as early as we are, Lightning has proven to be a radical improvement on the user experience of bitcoin. On the bitcoin network, fees vary but typically range from $1–5 and complete with confirmation in an average of ten minutes. With Lightning, fees and transaction times drop dramatically: the transaction fees are generally 1/100th or 1/10th of a penny and take just seconds.
If the improvements of Lightning are clear, why isn’t everyone using it today? Listen to hear more about the challenges and solutions coming to this rapidly-evolving aspect of bitcoin.

South Africa announced their discovery of the Omicron variant to the world as quickly as they could. The response from many nations was panic and the closure of transport links with southern Africa. Tulio de Oliveira who made the initial announcement and leads South Africa’s Centre for Epidemic Response and Innovation tells us this is now having a negative effect on the country, with cases rising but vital supplies needed to tackle the virus not arriving thanks to the blockade.
Omicron contains many more mutations than previous variants. However scientists have produced models in the past which can help us understand what these mutations do. Rockefeller University virologist Theodora Hatziioannou produced one very similar to Omicron and she tells us why the similarities are cause for concern.

Laura Figueroa from University of Massachusetts in Amhert in the US, has been investigating bees’ digestive systems. Though these are not conventional honey bees, they are Costa Rican vulture bees. They feed on rotting meat, but still produce honey.
And, What makes things sticky? Listener Mitch from the USA began wondering while he was taking down some very sticky wallpaper. Our world would quite literally fall apart without adhesives. They are almost everywhere – in our buildings, in our cars and in our smartphones. But how do they hold things together?
To find out, presenter Marnie Chesterton visits a luthier, Anette Fajardo, who uses animal glues every day in her job making violins. These glues have been used since the ancient Egyptians –but adhesives are much older than that. Marnie speaks to archaeologist Dr Geeske Langejans from Delft University of Technology about prehistoric glues made from birch bark, dated to 200,000 years ago. She goes to see a chemist, Prof Steven Abbott, who helps her understand why anything actually sticks to anything else. And she speaks to physicist Dr Ivan Vera-Marun at the University of Manchester, about the nanotechnologists using adhesion at tiny scales to make materials of the future.
