Electrical experiments with plants that count and communicate

Von Plicatus EN in Wissenschaft & Technik 1394 Aufrufe 13th November 2017 Video Dauer: N/A
Neuroscientist Greg Gage takes sophisticated equipment used to study the brain out of graduate-level labs and brings them to middle- and high-school classrooms (and, sometimes, to the TED stage.) Prepare to be amazed as he hooks up the Mimosa pudica, a plant whose leaves close when touched, and the Venus flytrap to an EKG to show us how plants use electrical signals to convey information, prompt movement and even count.

How do we make sense of today's political divisions? In a wide-ranging conversation full of insight, historian Yuval Harari places our current turmoil in a broader context, against the ongoing disruption of our technology, climate, media -- even our notion of what humanity is for. This is the first of a series of TED Dialogues, seeking a thoughtful response to escalating political divisiveness. Make time (just over an hour) for this fascinating discussion between Harari and TED curator Chris Anderson.

World Humanitarian Day 2016 United Nations
United Nations - Every day, humanitarian aid workers stand on the front lines of war and disaster, braving tremendous dangers and difficulties to deliver assistance to those who need it most. World Humanitarian Day (WHD), which takes place every year on 19 August, recognizes the aid workers who risk their lives in humanitarian service, and mobilizes people to advocate for humanitarian action. The day was designated by the General Assembly seven years ago to coincide with the anniversary of the 2003 bombing of the United Nations headquarters in Baghdad, Iraq. This World Humanitarian Day, the UN and its partners are calling for global solidarity with the more than 130 million people around the world who need humanitarian assistance to survive. Under the theme of ‘One Humanity’, World Humanitarian Day will highlight how the world came together in Istanbul for the World Humanitarian Summit earlier this year, and made commitments to support people affected by crisis and ensure that aid workers can safely and more effectively deliver to those in need.
