Turtles are built like tiny tanks—ancient, armored, and famously tough. But in the modern world, that toughness may be their greatest vulnerability. In part two of our turtle two-parter, we dive into the shadowy world of turtle trafficking, where backyard collectors, international smugglers, and unsuspecting pet owners all play a role. From sting operations to turtle triage, we meet the unlikely defenders working to stop t...

Turtles have been around for 200 million years—outliving dinosaurs, surviving ice ages, and basically minding their own business the whole time. Tough on the outside, chill on the inside, they seem built to last. So why are they suddenly disappearing? In part one of this two-part series, we hit the trail in search of one surprisingly elusive reptile: the eastern box turtle. These ancient creatures may seem slow, but their ...

Leeches don’t get a lot of love. They’re slimy, wriggly, and, well, they suck—blood that is. But there’s a lot to learn about the lowly leech. Led by a troupe of Smithsonian experts, we’ll discover how these toothy hangers-on wormed their way into medical practices, performance art, and EVERY human cavity. Yes, even that one. It's a journey of discovery from the swamp to the stage and deep into the vaults of the Smithsonia...

The Gilded Age was a time of unparalleled wealth and prosperity in America — but it was also a time of staggering inequality, corruption, and unchecked power. Among its richest figures was Andrew Carnegie, the steel magnate who built his fortune on the backs of low-paid workers, only to give it away — earning him the nickname the Godfather of American Philanthropy. He didn’t just fund libraries and universities — he champi...

If you were curating a mixtape that might be heard by aliens billions of years from now - but definitely would be seen by your fellow Earthlings - what would you put on it? In 1977, two Voyager spacecraft launched from Cape Canaveral on a journey that would take them beyond our solar system. Affixed to the side of these two planetary explorers was the Voyager Golden Record — the ultimate mixtape of humanity — containing 27...

The Curious Case of the Dizzy Kudu. Rhinos with an unexplained skin disease. A lion that could barely chew. Who do you call when there's a mystery at the zoo? The Smithsonian National Zoo and Conservation Biology Institute's anatomical pathologists. These highly-skilled vets search for clues to investigate animal disease and death — sometimes encountering bizarre phenomena. 

So, grab your microscope and get ready to head th...

From the time we’re old enough to hold a crayon, it feels instinctive to draw on the wall. But for MISS CHELOVE – also known as Cita Sadeli – this instinct became a calling. Through bold color and layered symbolism, she transforms everyday public spaces into deeply personal statements, inspiring some passers-by to wonder: what is the role of the public artist? And how can public art both reflect and shape a community's ide...

Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office or simply obliterate your niece at Words with Friends. And it's all made possible by rocks formed millions of years ago, deep underground. Join us as we bust open our devices to figure out how these stones power our phones.

The United States has more martial arts schools than any other country – by far. Chances are you or someone you know practiced karate or another martial art growing up. While martial arts gained popularity in the U.S. for many reasons, one name stands out: Jhoon Rhee. Known as the Father of American Taekwondo, Rhee famously taught Bruce Lee how to kick and Muhammed Ali how to punch. His bare-knuckled American dream made an...

A billion-dollar spacecraft, a daring deep-space mission, and one of humanity’s biggest questions: Where did we come from? NASA’s OSIRIS-REx set out to collect a pristine sample from asteroid Bennu, a cosmic time capsule that may hold clues to the origins of life in our solar system. But the journey was anything but easy.

When we think of serial killers, we tend to think of men—Ted Bundy, Jeffrey Dahmer, Jack the Ripper. But in the 1800s, the deadliest killers often wore corsets. In fact, so many women were arrested for serial poisoning that the era became known as the “Golden Age of Arsenic.” Journey back in time to trace the crimes of Lydia Sherman, a Victorian Era femme fatale who left a trail of bodies in her wake. How did she — and wom...

There was a time, before Neil Armstrong set foot on the moon, when some researchers believed women were better suited for space than men. In 1961, a group of female pilots—today known as the Mercury 13—quietly aced NASA’s toughest astronaut tests, even outperforming the Mercury men in some areas. But with the space race heating up, their mission was grounded— but not by science. But what became of America’s first female as...

Beyoncé is one of the most well-known and appreciated Black women in music today, but to understand her work, we need to look at who came before her and what those women contributed to the story of Black women on stage. In this special guest episode, curator Krystal Klingenberg introduces a new season of Collected, a podcast from the Smithsonian’s National Museum of American History, all about Black women in music.

Whether it's live on the Smithsonian National Zoo's panda cam or in front of a crowd, possibly no other animal's sex life is as closely watched as the giant pandas' is. And there's a reason. These cuddly-looking black and white bears just can't figure out how to mate. But, with a little help from science, the once-endangered giant panda is making a comeback. To honor the arrival of the National Zoo's newest giant pandas, w...

Children say it every day in school, but have you ever wondered why we recite the pledge of allegiance? We journey back to the late 1800s to understand how a massive wave of immigration and sagging magazine subscriptions gave rise to this vow of patriotism. From the Civil War to anti-immigrant nativism and Cold War politics, this one pledge tells many stories.

"I’m not superstitious, but I’m a little stitious.” As the New Year approaches, this iconic line from The Office feels more relatable than ever. From gulping grapes in Spain to donning yellow underwear in South America and practicing Scotland’s ancient “first-footing” tradition, people around the world embrace odd – and oddly meaningful - rituals to ensure good luck in the year ahead. Join us as we travel around the Smiths...

Sojourner Truth was a women's rights advocate known best for her famous speech "Ain't I a Woman." But Truth never actually said these words. In fact, much of the Truth we know… is fiction. Depictions from different artists and journalists have tweaked Truth's legacy to fit their messages, giving her a “kaleidoscopic reputation,” according to Nell Irvin Painter, author of Sojourner Truth: A Life, A Symbol.  

So how did a spe...

Edmonia Lewis was the first sculptor of African American and Native American (Mississauga) descent to achieve international fame. Her 3,000-pound masterwork, “The Death of Cleopatra,” commemorated another powerful woman who broke with convention… and then the sculpture disappeared. On this return episode of Sidedoor, we find them both. 

You can see "The Death of Cleopatra" at the Smithsonian American Art Museum. The new exh...

Imagine this: invisible robbers break into a bank and steal massive sacks of cash, but instead of running away with it they set their haul on the front stoop of the bank in a glass case. Everyone can see the money, but only the robbers can get to it. That’s how IRS Special Agent Chris Janczewski describes the 2016 Bitfinex heist – when mystery hackers made out with over $70 million in Bitcoin. By 2020, their loot had ballo...
