  There may be extraterrestrial life in our solar system - Augusto Carballido 17.09.2026 8分

  Is there extraterrestrial life in our solar system? Or are we alone? Take a journey to the ocean worlds on Jupiter and Saturn to investigate the possibility. --Deep in our solar system, a new era of exploration is unfolding. Beneath the thick ice of Europa; in the vapor plumes on Enceladus; and within the methane lakes of Titan, scientists are hunting for extraterrestrial life. These moons are ‘ocean worlds’— they contain liquid oceans, which can support the formation of life. Does life exist on ocean worlds? Augusto Carballido explores the possibility.Lesson by Augusto Carballido, directed by Artrake Studio.Sign up for our newsletter: http://bit.ly/TEDEdNewsletterSupport us on Patreon: http://bit.ly/TEDEdPatreonFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagramView full lesson: https://ed.ted.com/lessons/there-may-be-extraterrestrial-life-in-our-solar-system-augusto-carballidoThank you so much to our patrons for your support!

  How does alcohol lead to blackouts? - Shannon Odell 17.09.2026 6分

  Explore how alcohol interacts with your brain, and how it can interrupt the brain’s memory networks, leading to blackouts.--Alcohol has been shown to have strange and selective effects on the brain.

  Can sunlight improve your heart health? - Richard Weller 17.09.2026 16分

  Our bodies get Vitamin D from the sun, but as dermatologist Richard Weller suggests, sunlight may confer another surprising benefit too. New research by his team shows that nitric oxide, a chemical transmitter stored in huge reserves in the skin, can be released by UV light, to great benefit for blood pressure and the cardiovascular system. What does it mean? Well, it might begin to explain why Scots get sick more than Australians ... Talk by Richard Weller. Learn more about your ad choices. Visit megaphone.fm/adchoices

  The asteroid that came close to erasing life on Earth - Sean P. S. Gulick 17.09.2026 8分

  Dig into what happened after the Chicxulub asteroid hit the Earth, and how it caused a mass extinction— including dinosaurs.--Sixty-six million years ago, near what’s now the Yucatán Peninsula, a juvenile sauropod feasted on horsetail plants on a riverbank. Earth was a tropical planet. Behemoth and tiny dinosaurs alike soared its skies and roamed its lands while reptiles and tentacled ammonites swept its seas. But, in an instant, everything would change. Sean P. S. Gulick details one of Earth's most devastating periods.Lesson by Sean P. S.

  View full lesson: http://ed.ted.com/lessons/is-there-a-difference-between-art-and-craft-laura-morelliWas da Vinci an artistic genius? Sure, but he was also born in the right place at the right time -- pre-Renaissance, Western artists got little individual credit for their work. And in many non-Western cultures, traditional forms have always been prized over innovation. So, where do we get our notions of art vs. craft?

  What's the science behind whale communication? - David Gruber and Shane Gero 17.09.2026 8分

Within just a few years, whalers saw a 58% drop in their successful strikes. Sperm whales had suddenly become harder to kill— they had begun fleeing the boats instead of forming their usual defensive circles. Were whales communicating new strategies to each other?

  Can planting trees actually cool the planet? - Carolyn Beans 17.09.2026 8分

  Dig into common mistakes that tree-planting programs make, and explore strategies that can successfully re-green the planet.--In fighting climate change, few solutions are discussed more than planting lots and lots of trees.
