Axolotls are nature’s great regenerators. They are able to grow back not just their tails, but also legs, arms, even parts of vital organs, including their hearts. This remarkable ability is one of several traits that turned the axolotl into a scientific superstar. The axolotl is one of the most abundant laboratory animals in biology. They can be found swimming in tanks at universities all around the world. But in the wild they’ve only ever been found in one place: Mexico City.

In 2015 the world was divided into two warring factions overnight. And at the center of this schism was a single photograph. Cecilia Bleasdale took a picture of a dress that she planned to wear to her daughter's wedding and that photo went beyond viral. Some saw it as blue with black trim; others as white with gold trim. For his part, Wired science writer Adam Rogers knew there was more to the story -- a reason different people looking at the same object could come to such radically divergent conclusions about something as simple as color.

Rogers recently wrote a book titled Full Spectrum: How the Science of Color Made Us Modern. In this episode, Roman Mars talks with the author about how the pursuit to organize, understand, and create colors has been one of the driving forces shaping human history, starting with the story of this hotly debated piece of apparel from 2015 then winding back through built environments of global World's Fairs.

What does water mean to you? In this feature, author Bonnie Tsui (Why We Swim), actress Joy Bryant, submarine pilot Erika Bergman, figure skater Elladj Baldé, 85-year-old synchronized swimmer Barbara Eison-White, professional mermaid Olivia Gonzales, and others share stories about the many ways water influences our lives.

From Pop-Up Magazine, creators of this Field Guide series: "We recommend listening outside, near water if you can. Head to the ocean if you’re on the coast. Or walk to a nearby pond or creek. Sit by a fountain at a park. Or just pour yourself a glass of water."

Plus, an excerpt of Roman Mars On The Anatomy Of A Good Story (w/ Michelle Fournet, Roman Mars, Pedro Pascal), part of the Periodic Talks podcast. It's a show about what gets people curious, from virtual experiences to celestial bodies, with Gillian Jacobs (Community, Netflix's LOVE) and Diona Reasonover (NCIS)

When Roman Mars and Kurt Kohlstedt were promoting The 99% Invisible City in late 2020, one question came up over and over again in conversations and interviews about our built environment: in what ways will the COVID pandemic change cities long term? Realistically, it's hard to answer a question about the future while in the midst of a crisis, but we can look to and extrapolate from precedents, like: designs born out of past disasters.

Officially titled The Book of Tasty and Healthy Food, it was often known simply as “Kniga” (translated: "book") because it was one of the only cookbooks to exist in the Soviet Union. The volume is peppered with glossy photographs of really lavish spreads and packed with text as well. There are recipes for lentils and crab salad and how to cook buckwheat nine different ways. But this book was meant to do so much more than show people how to make certain dishes — it's a Stalinist document aimed at addressing hunger itself in the USSR. "The book" was at the vanguard of a radical Soviet food experiment that, despite its numerous obstacles, transformed Russian cuisine.

Britt Young is a geographer and tech writer based in the Bay Area. She also has what's called a "congenital upper limb deficiency." In other words, she was born without the part of her arm just below her left elbow. She's used different sorts of prosthetic devices her whole life, and in 2018, she celebrated the arrival of a brand new, multi-articulating prosthetic hand. This prosthetic hand has a sleek carbon fiber casing, with specific pre-programmed grips that she can control just by flexing the muscles in her residual limb. She can use a precision pinch to pick a hairpin off of the table, or a Hulk-style power fist to squeeze objects. This kind of assistive technology has been life-changing for a lot of people who have limb differences. But for Britt, in particular, it hasn't been life-changing at all. In fact, her cutting-edge bionic arm has been a pretty major disappointment. "It's just not what you imagine. It's not like I'm like everyone else now, it's something different."

Hanko, sometimes called insho, are the carved stamp seals that people in Japan often use in place of signatures. Hanko seals are made from materials ranging from plastic to jade and are about the size of a tube of lipstick. The end of each hanko is etched with its owner’s name, usually in the kanji pictorial characters used in Japanese writing. This carved end is then dipped in red cinnabar paste and impressed on a document as a form of identification. Hanko seals work like signatures, only instead of signing on a dotted line, you impress your hanko in a small circle to prove your identity. But unlike a signature, which you can make with any old pen or touch screen, in Japan you need to have your own personal hanko with you whenever you stamp something, and you have to stamp it in person.

Throughout its reign, the British Empire stole a lot of stuff. Today those objects are housed in genteel institutions across the UK and the world. They usually come with polite plaques. The ABC podcast Stuff the British Stole is a six episode series about the not-so-polite history behind a few of those objects.

We’re going to play the first episode and Roman talks to the presenter and creator Marc Fennell about the series.

Every year, fights break out on airplanes. They happen between the people who lean back in their seats, and the people who get their knees smooshed. Sometimes planes have to be grounded because of these arguments. If you think about it, these arguments are the result of confusion. Both people paid for a seat on the airplane, but it's unclear who owns the space behind it. Jim Salzman and Michael Heller are law professors and the authors of a new book called Mine! How the Hidden Rules of Ownership Control Our Lives. They write about these common instances where ownership is not clear cut. According to Salzman and Heller, confusing ownership rules are often the result of poor ownership design. This is true not just for airplane seats, but also for battles over digital privacy, climate change, and wealth inequality.

We revisit Katie Mingle's Right to Roam episode as we say goodbye

In the United Kingdom, the freedom to walk through private land is known as “the right to roam.” The movement to win this right was started in the 1930s by a rebellious group of young people who called themselves “ramblers” and spent their days working in the factories of Manchester, England.
