👁Why fish are better at breathing than you are
🧠Dan Kwartler
🗣Subtitle: 🇬🇧English

👣Recent studies found that elite runners can take in twice as much oxygen as non-runners. And it’s likely that this superhuman ability played a role in breaking the two-hour marathon barrier in 2019. But when it comes to breathing efficiently, not even the best runners can compete with the average fish. What makes fish some of the best breathers on Earth? Dan Kwartler explores the science of gills. [Directed by Denys Spolitak, narrated by Addison Anderson, music by Salil Bhayani, cAMP Studio].

👁Why do snakes have forked tongues?
🧠Cella Wright
🗣Subtitle: 🇬🇧English

👣An alligator snapping turtle lures its prey using a blood-engorged tongue that resembles a wriggling worm. And it’s far from the only animal doing tongue trickery. Tongues in the animal kingdom vary widely — from texture and length, to shape and dexterity. So, what's the point of having so many different kinds of tongues? Cella Wright explores how different species use the appendage to survive. [Directed by Igor Ćorić, Artrake Studio, narrated by Susan Zimmerman, music by Cem Misirlioglu].

👁Why are scientists shooting mushrooms into space?
🧠Shannon Odell
🗣Subtitle: 🇬🇧English

👣Astronauts aboard the space station Mir made a frightening discovery: several species of Earth-derived fungi were found growing throughout the shuttle, blanketing air conditioners and corroding control panels, putting both the station’s integrity and their lives at risk. How had the fungi survived the journey to space? Shannon Odell shares why fungi may be the key to our future on other planets. [Directed by Denys Spolitak, narrated by Alexandra Panzer, music by Stephen LaRosa].

👁The satellite helping slow climate change — right now
🧠Millie Chu Baird
🗣Subtitle: 🇬🇧English

👣Meet MethaneSAT: the satellite circling Earth right now to track global emissions from methane: a highly potent, short-term greenhouse gas. Environmental advocate Millie Chu Baird details the heat-trapping side effects of a planet full of methane — and explains why understanding where it comes from and taking steps to reduce it is the single most important thing we can do to affect climate change in our lifetimes. (MethaneSAT is part of the Audacious Project, TED's initiative to inspire and fund global change.)

👁Why does hitting your funny bone feel so horrible?
🧠Cella Wright
🗣Subtitle: 🇬🇧English

👣It's something we've all experienced: the back of your elbow smacks against a hard surface and the impact sends a sensation so distinctly disquieting shooting down your arm that it takes several moments to regain composure. So, why does hitting this spot on your elbow— commonly known as the funny bone— feel so weird? Cella Wright explains one of the most complicated joints in the body. [Directed by Anton Bogaty, narrated by Susan Zimmerman, music by Salil Bhayani, cAMP Studio].

👁The secret force for limitless energy? Lasers
🧠Tammy Ma
🗣Subtitle: 🇬🇧English

👣In 2022, physicist Tammy Ma and her team achieved a scientific breakthrough decades in the making: fusion ignition, or the combining of two atoms to generate more energy out of a reaction than was put in — recreating on Earth the same process that powers the Sun. She explains how they used a giant laser (way, way bigger than you're thinking) to catalyze this reaction and shares a vision for how this technology could change the world by creating limitless clean energy.

👁Quantum computers aren't what you think — they're cooler
🧠Hartmut Neven
🗣Subtitle: 🇬🇧English

👣Quantum computers obtain superpowers by tapping into parallel universes, says Hartmut Neven, the founder and lead of Google Quantum AI. He explains how this emerging tech can far surpass traditional computers by relying on quantum physics rather than binary logic, and shares a roadmap to build the ultimate quantum computer. Learn how this fascinating and powerful tech can help humanity take on seemingly unsolvable problems in medicine, sustainable energy, AI, neuroscience and more.

👁The most dangerous elements on the periodic table
🧠Shannon Odell
🗣Subtitle: 🇬🇧English | 🇹🇷Turkish

👣Within the periodic table loom many potential hazardous elements. Some elements are dangerous due to their toxicity. Others are dangerous because of how they respond, react, or even explode in the outside environment. And perhaps the most threatening elements are those that silently emit energy. So, which substances on the periodic table are the most dangerous? Shannon Odell investigates. [Directed by Anton Bogaty, narrated by Pen-Pen Chen, music by Cem Misirlioglu].

👁Why is it so dangerous to step on a rusty nail?
🧠Louise Thwaites
🗣Subtitle: 🇬🇧English | 🇹🇷Turkish

👣In the 5th century, a ship master was suffering from a nasty infection that caused his jaws to press together, his teeth to lock up, and the muscles in his neck and spine to spasm. Today we know this account to be one the first recorded cases of tetanus. So, what causes this peculiar infection? Louise Thwaites explores how tetanus affects our bodies, and how we can prevent it.
