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

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.

Iceland's secret power - Jean-Baptiste P. Koehl

Explore how geothermal energy— the heat in the Earth’s crust— is being used to create renewable electricity and power. -- While the weather in Iceland is often cold, wet, and windy, a nearly endless supply of heat bubbles away below the surface. In fact, almost every building in the country is heated by geothermal energy in a process with virtually no carbon emissions. So how exactly does this renewable energy work? Jean-Baptiste P. Koehl explores the two primary models for harnessing the planet's natural heat. Lesson by Jean-Baptiste P. Koehl, directed by Charlotte Arene.

Creating a dinosaur from a chicken - Jack Horner

View full lesson: http://ed.ted.com/lessons/building-a-dinosaur-from-a-chicken-jack-horner [http://ed.ted.com/lessons/building-a-dinosaur-from-a-chicken-jack-horner] Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking living descendants of the dinosaur (chickens) and genetically engineering them to reactivate ancestral traits — including teeth, tails, and even hands — to make a "Chickenosaurus".

Deciphering a visible quantum object - Aaron O'Connell

Physicists are used to the idea that subatomic particles behave according to the bizarre rules of quantum mechanics, completely different to human-scale objects. In a breakthrough experiment, Aaron O'Connell has blurred that distinction by creating an object that is visible to the unaided eye, but provably in two places at the same time. In this talk he suggests an intriguing way of thinking about the result. Talk by Aaron O'Connell. Learn more about your ad choices. Visit megaphone.fm/adchoices [https://megaphone.fm/adchoices]
