TED Talks Science and Medicine Folgen

In this perspective-shifting talk, Danny Hillis prompts us to approach global issues like climate change with creative scientific solutions. Taking a stand for solar geoengineering, he looks at controversial solutions with open-minded curiosity.

Each year, the world loses enough food to feed half a billion people to fungi, the most destructive pathogens of plants. Mycologist and TED Fellow Mennat El Ghalid explains how a breakthrough in our understanding of the molecular signals fungi use to attack plants could disrupt this interaction -- and save our crops.

"Hold your breath," says inventor Tom Zimmerman. "This is the world without plankton." These tiny organisms produce two-thirds of our planet's oxygen -- without them, life as we know it wouldn't exist. In this talk and tech demo, Zimmerman and cell engineer Simone Bianco hook up a 3D microscope to a drop of water and take you scuba diving with plankton. Learn more about these mesmerizing creatures and get inspired to protect them against ongoing threats from climate change.
