You're cruising down the highway when all of a sudden endless rows of brake lights appear ahead. There's no accident, no stoplight, no change in speed limit, or narrowing of the road. So why is there so much traffic? It's due to a phenomenon called a phantom traffic jam. Benjamin Seibold explains why it happens and how we might prevent it in the future. [Directed by Cris Wiegandt, narrated by Addison Anderson, music by André Aires, AIM Creative Studios].
A mountain separating two lakes. A room papered floor to ceiling with bridal satins. The lid of an immense snuffbox. These seemingly unrelated images take us on a tour of a sperm whale's head in Herman Melville's "Moby Dick." Though the book features pirates, typhoons, high-speed chases, and giant squid, it's anything but a conventional seafaring adventure. Sascha Morrell digs into the classic novel. [Directed by Martina Meštrović, narrated by Adrian Dannatt, music by Stephen LaRosa].
In the 16th century, physician Andreas Vesalius described how a suffocating animal could be kept alive by inserting a tube into its trachea and blowing air to inflate its lungs. Today, Vesalius's treatise is recognized as the first description of mechanical ventilation— a crucial practice in modern medicine. So how do our modern ventilators work? Alex Gendler explains the life-saving technology. [Directed by Artrake Studio, narrated by Addison Anderson].
The evil wizard MoldeVort has been trying to kill you for years, and today it looks like he's going to succeed. But your friends are on their way, and if you can survive until they arrive, they should be able to help stop him. Can you keep MoldeVort trapped long enough for help to arrive? Dan Finkel shows how. [Directed by Artrake Studio, narrated by Addison Anderson].
A new virus emerges and spreads like wildfire. In order to contain it, researchers must first collect data about who's been infected. Two main viral testing techniques are critical: one tells you if you have the virus and the other shows if you've already had it. So, how exactly do these tests work? Cella Wright explores the science of PCR tests and immunoassays. [Directed by Hype CG, narrated by Bethany Cutmore-Scott, music by Gabriel Maia].
For almost a decade, scientists chased the source of a deadly new virus through China's tallest mountains and most isolated caverns. They finally found it in the bats of Shitou Cave. The virus in question was a coronavirus that caused an epidemic of severe acute respiratory syndrome, or SARS, in 2003. So what exactly is a coronavirus, and how does it spread? Elizabeth Cox explains. [Directed by Anton Bogaty, narrated by Bethany Cutmore-Scott, music by Jarrett Farkas].
The midwife Xoquauhtli has a difficult choice to make. She owes a debt to her patron Teteoinnan, the female warrior goddess at the center of the Aztec seasonal festival, who must be kept happy or she will bring bad luck. Xoquauhtli should participate in the festival today, but one of her patients could go into labor any minute. Kay Read outlines a day in the life of an Aztec midwife. [Directed by AIM Creative Studios, narrated by Bethany Cutmore-Scott, music by André Aires].
In the 1980s and 90s, pharmaceutical companies began to market opioid painkillers aggressively, while actively downplaying their addictive potential. The number of prescriptions skyrocketed, and so did cases of addiction, beginning a crisis that continues today. What makes opioids so addictive? Mike Davis explains what we can do to reverse the skyrocketing rates of addiction and overdose. [Directed by Good Bad Habits, narrated by Addison Anderson, music by Landon Trimble/ Playdate].
Your hands, up close, are anything but smooth. With peaks and valleys, folds and rifts, there are plenty of hiding places for a virus to stick. If you then touch your face, the virus can infect you. But there are two extraordinarily simple ways you can keep that from happening: soap and water, and hand sanitizer. So which is better? Alex Rosenthal and Pall Thordarson investigate. [Directed by Artrake Studio, narrated by Addison Anderson].
You've been accused of a crime you did not commit. It's impossible to prove your innocence. If you insist that you're innocent anyway, you'll likely be found guilty and executed. But if you confess, apologize, and implicate others, you'll go free. This was the choice facing those accused of witchcraft in Salem, Massachusetts in the 17th century. How did this happen? Brian A. Pavlac investigates. [Directed by Lucy Animation Studio, narrated by Susan Zimmerman, music by Stephen LaRosa].
By 2050, it's estimated that over 65% of the world will be living in cities. We may think of nature as being unconnected to our urban spaces, but trees have always been an essential part of successful cities. Humanity has been uncovering these arboreal benefits since the creation of our first cities thousands of years ago. So what makes trees so important to a city's survival? Stefan Al explains. [Directed by Mette Ilene Holmriis, narrated by Addison Anderson, music by Bamm Bamm Wolfgang].
Australians call them "runners." The British know them as "trainers." Americans refer to them as "sneakers." Whatever you call them, these casual shoes are worn by billions of people around the world. Today, roughly 23 billion shoes are produced each year. So, how can we balance our love of sneakers with the need for sustainability? Angel Chang explores how shoe manufacturing impacts our planet. [Directed and animated by Ella Dobson, narrated by Addison Anderson, music by Stephen LaRosa].
A baby cursed at birth. A fierce battle of good and evil. A true love awoken with a kiss. Since premiering in 1890, "The Sleeping Beauty" has become one of the most frequently staged ballets in history. So what makes this piece so beloved? And what exactly does ballet bring to this— or any other— story? Ming Luke shares what makes ballet the perfect medium for stories old and new. [Directed by Visorama, narrated by Addison Anderson, music by Jarrett Farkas].
This is episode 8 of our animated series "Think Like A Coder." This 10-episode narrative follows a girl, Ethic, and her robot companion, Hedge, as they attempt to save the world. The two embark on a quest to collect three artifacts and must solve their way through a series of programming puzzles. [Directed by Kozmonot Animation Studio, narrated by Addison Anderson].
Aphids can reproduce incredibly fast: they can make 20 new generations within a single season. And that means lots of poop. Some aphid populations can produce hundreds of kilograms of poop per acre— making them some of the most prolific poopers on the planet. We know this poop as the sweet, syrupy liquid called honeydew. George Zaidan explores the wonderfully weird life of an aphid. [Directed by Hype CG, narrated by George Zaidan, music by Gabriel Maia].
Throughout her life, Rosa Parks repeatedly challenged racial violence and the prejudiced systems protecting its perpetrators. Her refusal to move to the back of a segregated bus ignited a boycott that lasted 381 days and helped transform civil rights activism into a national movement. But this work came at an enormous risk— and a personal price. Riché D. Richardson details the life of Rosa Parks. [Directed by Eido, narrated by Christina Greer, music by John Poon].
Ethanol: this molecule, made of little more than a few carbon atoms, is responsible for drunkenness. Often simply referred to as alcohol, ethanol is the active ingredient in alcoholic beverages. So how exactly does it cause drunkenness, and why does it have dramatically different effects on different people? Judy Grisel explores alcohol's journey through the body. [Directed by Anton Bogaty, narrated by Bethany Cutmore-Scott].
The Monkey King, a legendary troublemaker hatched from stone and schooled in divine magic, had stolen the Dragon Lord's most treasured weapon: a magical staff. Returning to his kingdom to show off his treasure to his tribe of warrior monkeys, he finds himself caught in the clutches of two soul collectors, dragging him to his death. Shunan Teng details the Monkey King's journey to the underworld. [Directed by Yijia Cao & Mohammad Babakoohi, narrated by Bethany Cutmore-Scott, music by Epidemic Sound].
It was one of the strangest trials in Dutch history. The defendant in a 1947 case was an art forger who had counterfeited millions of dollars worth of paintings. But he wasn't arguing his innocence— in fact, his life depended on proving that he had committed fraud. Who was this artist, and why was he on trial for his life? Noah Charney investigates the notorious Han van Meegeren. [Directed by Hype CG, narrated by Addison Anderson, music by Gabriel Maia].
According to legend, once every thousand years a host of sea monsters emerges from the depths to demand tribute from the floating city of Atlantartica. As the ruler of the city, you'd always dismissed the stories... until today, when they rose out of the roiling waters, surrounded your city and demanded a ransom of pearls. Can you figure out which chest of pearls is the ransom? Dan Finkel shows how. [Directed by Artrake Studio, narrated by Addison Anderson].
