Which country does the most good for the world? – Simon Anholt – video

Simon Anholt: Which country does the most good for the world?

It’s an unexpected side effect of globalization: problems that once would have stayed local—say, a bank lending out too much money—now have consequences worldwide. But still, countries operate independently, as if alone on the planet. Policy advisor Simon Anholt has dreamed up an unusual scale to get governments thinking outwardly: The Good Country Index.

In a riveting and funny talk, he answers the question, “Which country does the most good?” The answer may surprise you (especially if you live in the US or China).

Russell Foster: Why do we sleep?

Published on Aug 14, 2013 — Russell Foster is a circadian neuroscientist:  He studies the sleep cycles of the brain. And he asks: What do we know about sleep? Not a lot, it turns out, for something we do with one-third of our lives. In this talk, Foster shares three popular theories about why we sleep, busts some myths about how much sleep we need at different ages — and hints at some bold new uses of sleep as a predictor of mental health.

Parkinson’s, depression and the switch that might turn them off – TED video

Parkinson’s, depression and the switch that might turn them off  – TED talk by Andres Lozano

Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down — like a radio dial or thermostat — to correct dysfunction. Andres Lozano offers a dramatic look at emerging techniques, in which a woman with Parkinson’s instantly stops shaking and brain areas eroded by Alzheimer’s are brought back to life. (Filmed at TEDxCaltech.)

The chair of neurosurgery at the University of Toronto, Andres Lozano has pioneered the use of deep brain stimulation for treating Parkinson’s, depression, anorexia and Alzheimer’s disease. Full bio »

Juan Enriquez: Will our kids be a different species? video

Juan Enriquez: Will our kids be a different species?

Throughout human evolution, multiple versions of humans co-existed. Could we be mid-upgrade now? At TEDxSummit, Juan Enriquez sweeps across time and space to bring us to the present moment — and shows how technology is revealing evidence that suggests rapid evolution may be under way.

Juan Enriquez thinks and writes about profound changes that genomics will bring in business, technology, and society. His TED Book, “Homo Evolutis,” explores those changes.
“Since the 1940s, we’ve been saying there are no differences, we [humans] are all identical. We’re going to know at year end if that is true.”   Full bio »
