Moran Cerf: This scientist can hack your dreams

18:00 minutes · Filmed Feb 2016 · Posted May 2016 · TED2016

What if we could peek inside our brains and see our dreams -- or even shape them? Studying memory-specific brain cells, neuroscientist (and ex-hacker) Moran Cerf found that our sleeping brains retain some of the content we encounter when we're awake and that our dreams can influence our waking actions. Where could this lead us? "Neuroscientists are now giving us a new tool to control our dreams," Cerf says, "a new canvas that flickers to life when we fall asleep."

Anyone who has lost a loved one to pancreatic cancer knows the devastating speed with which it can affect an otherwise healthy person. TED Fellow and biomedical entrepreneur Laura Indolfi is developing a revolutionary way to treat this complex and lethal disease: a drug delivery device that acts as a cage at the site of a tumor, preventing it from spreading and delivering medicine only where it's needed. "We are hoping that one day we can make pancreatic cancer a curable disease," she says. Watch »

Sebastian Junger has seen war up close, and he knows the impact that battlefield trauma has on soldiers. But he suggests there's another major cause of pain for veterans when they come home: the experience of leaving the tribal closeness of the military and returning to an alienating and bitterly divided modern society. "Sometimes, we ask ourselves if we can save the vets," Junger says. "I think the real question is if we can save ourselves." (This talk comes from the PBS special TED Talks: War & Peace, which premieres Monday, May 30.) Watch »

Everyone has an opinion about how to legislate sex work (whether to legalize it, ban it or even tax it) ... but what do workers themselves think would work best? Activist Toni Mac explains four legal models that are being used around the world, and shows us the model that she believes will work best to keep sex workers safe and offer greater self-determination. "If you care about gender equality or poverty or migration or public health, then sex worker rights matter to you," she says. "Make space for us in your movements." (Adult themes) Watch »

In the US, the press has a right to publish secret information the public needs to know, protected by the First Amendment. But government surveillance has made it ever more dangerous for whistleblowers, the source of virtually every important story about national security since 9/11, to share information. In this concise, informative talk, Freedom of the Press Foundation co-founder and TED Fellow Trevor Timm traces the recent history of government action against individuals who expose crime and injustice, and advocates for technology that can help them do it safely and anonymously.

Quote of the Week


Charles Darwin said, 'I sometimes think that general and popular treatises are almost as important for the progress of science as original work.' In fact, Origin of Species was written for a general and popular audience, and was widely read when it first appeared. Darwin knew what we seem to have forgotten, that science is not only for scientists."
