Using video, images and music, professional skeptic Michael Shermer explores these and other phenomena, including UFOs and alien sightings. He offers cognitive context: In the absence of sound science, incomplete information can combine with the power of suggestion (helping us hear those Satanic lyrics in Led Zeppelin). In fact, he says, humans tend to convince ourselves to believe: We overvalue the “hits” that support our beliefs, and discount the more numerous “misses.”... Read More إقرأ المزيد | Share it now!

http://www.ted.com In this hopeful talk, 2006 TED Prize winner Jehane Noujaim unveils her wish: a global acceptance of diversity, mediated through the power of film. The first step? Getting people to understand each other. In 2003, Noujaim gained access to both sides of the story of the Iraq war for her film Control Room, a dichotomy she illustrates with provocative clips of Al Jazeera journalist Sameer Khader and U.S. press officer Josh Rushing. Noujaim ends by outlining her plans for Pangea Day, an event in which people all over the world can watch the same films at the same time. (Contains strong language.)...

http://www.ted.com Alan Russell studies regenerative medicine — a breakthrough way of thinking about disease and injury by helping the body to rebuild itself. He shows how engineered tissue that “speaks the body’s language” has helped a man regrow his lost fingertip, how stem cells can rebuild damaged heart muscle, and how cell therapy can regenerate the skin of burned soldiers. This new, low-impact medicine comes just in time, Russell says — our aging population, with its steeply rising medical bills, will otherwise (and soon) cause a crisis in health care systems around the world. Some graphic medical imagery.... Read More إقرأ المزيد | Share it now!
