👁How space changes an astronaut’s body
🧠Tejal Gala
🗣Subnoscript: 🇬🇧English

👣Imagine a scientist who has teleported to space. His spacesuit’s pressurized air protects his bodily fluids from vaporization, its oxygen tank keeps him breathing, and the insulation prevents him from freezing. But although these features thwart an immediate tragedy, space is still an incredibly dangerous place. So, what does a prolonged stay in space do to the human body? Tejal Gala investigates. [Directed by Henrique Barone, narrated by Jack Cutmore-Scott, music by Jan Willem de With].

👁The surprising reason zebras have stripes
🧠Cella Wright
🗣Subnoscript: 🇬🇧English | 🇹🇷Turkish

👣Zebras belong to the same equine family as horses and donkeys. After their lineage entered Africa, they evolved into three zebra species, lived in social herds, grazed on grasses, and evaded fierce predators. One mystery that has perplexed prominent scientists for decades is the matter of their coats: why are they striped? Cella Wright digs into the common theories about the unique patterning. [Directed by Sharon Colman, narrated by Addison Anderson, music by Jarrett Farkas].

👁What does appendix pain feel like?
🧠David R. Flum
🗣Subnoscript: 🇬🇧English | 🇹🇷Turkish

👣In 1961, an Antarctic expedition took a harrowing turn: Dr. Leonid Rogozov began feeling feverish, with an excruciating pain in his right side. It soon became clear that he had appendicitis. While Rogozov’s predicament was extreme, appendicitis is not uncommon; affecting roughly one in 12 people. So, what causes appendicitis? And why is this organ so prone to bursting? David R. Flum investigates. [Directed by Igor Ćorić, Artrake Studio, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].

👁How do animals regrow their limbs? And why can't humans do it?
🧠Jessica Whited
🗣Subnoscript: 🇬🇧English

👣For some animals, losing a limb is a decidedly permanent affair. But for salamanders, particularly axolotls, amputation is just a temporary affliction. Not only can they grow back entire limbs in as little as six weeks, they can also regenerate heart and even brain tissue. So, how does this astonishing adaptation work? Jessica Whited explores the incredible regenerative capacity of salamanders. [Directed by Anton Bogaty, narrated by Jack Cutmore-Scott, music by Cem Misirlioglu, WORKPLAYWORK].

👁A mouse with two dads — and a new frontier for biology
🧠Katsuhiko Hayashi
🗣Subnoscript: 🇬🇧English

👣You're familiar with the story: a sperm and an egg meet to create an embryo, which has the potential to give rise to new life. But what if you could create a sperm or egg from any cell, even a single skin cell? Biologist Katsuhiko Hayashi discusses the science of in vitro gametogenesis (IVG) — an experimental technique for creating lab-made sperm or eggs out of just about any type of cell — and explores its implications for endangered species, human reproduction and more.

👣Andre and Leslie are a deaf couple who have decided to have a child, and they’re considering using a process to ensure deafness in their child. As deaf parents, they feel they could provide better guidance to a child that would share their lived experience and grow up immersed in deaf culture. But is this genetic intervention ethical?

👁Why animals help each other
🧠Ashley Ward
🗣Subnoscript: 🇬🇧English | 🇹🇷Turkish

👣Charles Darwin introduced the notion of “survival of the fittest,” where the fittest animals are those who can survive long enough to produce healthy offspring. The fittest animal can also be the most stealthy, resourceful, or even the most cooperative. So what exactly does cooperation look like in the wild?

👁Can you figure out the savanna mystery?
🧠Cella Wright
🗣Subnoscript: 🇬🇧English | 🇹🇷Turkish

👣In the early 2000s, one of the world’s most widespread invasive species landed in Kenya’s Laikipia Plateau: big-headed ants. They expanded rapidly into super-colonies, preying on other insects, spiders, and even small birds. Their presence has wreaked havoc on the ecosystem and significantly changed the landscape. So, how did these tiny creatures have such a huge impact? Cella Wright investigates. [Directed by Steve West, Lazy Chief, narrated by Addison Anderson, music by George Rodriguez].

👁How does light therapy help treat seasonal depression?
🧠Kelly Rohan
🗣Subnoscript: 🇬🇧English | 🇹🇷Turkish

👣As winter approaches, shorter days spark a cascade of changes within the brains of animals. As a result, groundhogs retreat to their burrows for hibernation, weasels’ coats turn from brown to white, and birds cease their singing. And scientists are finding that seasonal behavioral changes similarly happen for some humans. Kelly Rohan digs into what we know about seasonal affective disorder.
