Modern technology lets neuroscientists peer into the human brain, but can it also read minds? Armed with the device known as an electroencephalogram, or EEG, and some computing wizardry, our intrepid neuroscientists attempt to peer into a subject's thoughts.
Can the mind be manipulated to love a food we loathe? The evidence from fruit flies is compelling, and perhaps surprising. Our tag team of neuroscientists attempts to change a fly's preference for fruit over vegetables simply by shining a light on their brain.
Dragonflies can catch prey with near perfect accuracy, the best among all predators. But how does something with so few neurons achieve such prowess? Our intrepid neuroscientists explore how a dragonfly unerringly locks onto its preys and captures it within milliseconds using just sensors and a fake fly.
Thousands of years ago, ancient Nubians drew pictures on tomb walls of a terrible disease that turns the eyelids inside out and causes blindness. This disease, trachoma, is still a scourge in many parts of the world today -- but it's also completely preventable, says Caroline Harper. Armed with data from a global mapping project, Harper's organization Sightsavers has a plan: to focus on countries where funding gaps stand in the way of eliminating the disease and ramp up efforts where the need is most severe. Learn more about their goal of consigning trachoma to the history books -- and how you can help. (This ambitious idea is part of the Audacious Project, TED's initiative to inspire and fund global change.)
There's a creeping sameness in many of our newest urban buildings and streetscapes, says architect Vishaan Chakrabarti. And this physical homogeneity -- the result of regulations, mass production, safety issues and cost considerations, among other factors -- has blanketed our planet in a social and psychological homogeneity, too. In this visionary talk, Chakrabarti calls for a return to designing magnetic, lyrical cities that embody their local cultures and adapt to the needs of our changing world and climate.
Writer and artist James Bridle uncovers a dark, strange corner of the internet, where unknown people or groups on YouTube hack the brains of young children in return for advertising revenue. From "surprise egg" reveals and the "Finger Family Song" to algorithmically created mashups of familiar cartoon characters in violent situations, these videos exploit and terrify young minds -- and they tell us something about where our increasingly data-driven world is headed. "We need to stop thinking about technology as a solution to all of our problems, but think of it as a guide to what those problems actually are, so we can start thinking about them properly and start to address them," Bridle says.
What can we learn from the slimy, smelly side of life? In this playful talk, science journalist Anna Rothschild shows us the hidden wisdom of "gross stuff" and explains why avoiding the creepy underbelly of nature, medicine and technology closes us off to important sources of knowledge about our health and the world. "When we explore the gross side of life, we find insights that we never would have thought we'd find, and we even often reveal beauty that we didn't think was there," Rothschild says.
Netflix changed the world of entertainment -- first with DVD-by-mail, then with streaming media and then again with sensational original shows like "Orange Is the New Black" and "Stranger Things" -- but not without taking its fair share of risks. In conversation with TED curator Chris Anderson, Netflix co-founder and CEO Reed Hastings discusses the company's bold internal culture, the powerful algorithm that fuels their recommendations, the $8 billion worth of content they're investing in this year and his philanthropic pursuits supporting innovative education, among much more.
The global refugee crisis is a mental health catastrophe, leaving millions in need of psychological support to overcome the traumas of dislocation and conflict. To undo the damage, child psychiatrist and TED Fellow Essam Daod has been working in camps, rescue boats and the shorelines of Greece and the Mediterranean Sea to help refugees (a quarter of which are children) reframe their experiences through short, powerful psychological interventions. "We can all do something to prevent this mental health catastrophe," Daod says. "We need to acknowledge that first aid is not just needed for the body, but it has also to include the mind, the soul."
What happens when technology knows more about us than we do? Poppy Crum studies how we express emotions -- and she suggests the end of the poker face is near, as new tech makes it easy to see the signals that give away how we're feeling. In a talk and demo, she shows how "empathetic technology" can read physical signals like body temperature and the chemical composition of our breath to inform on our emotional state. For better or for worse. "If we recognize the power of becoming technological empaths, we get this opportunity where technology can help us bridge the emotional and cognitive divide," Crum says.
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.
When Gastón Acurio started his now world-famous restaurant Astrid & Gastón in the 1990s, no one suspected that he would elevate the Peruvian home-cooking he grew up with to haute cuisine. Nearly thirty years and a storied career later, the chef wants the rest of us to embrace our culinary roots and transform the world with the meals we prepare each day.

Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we're a small part of a complex, four-billion-year process -- and not the end of the line. "We're not the goal of evolution," Chakrabarty says. "Think of us all as young leaves on this ancient and gigantic tree of life -- connected by invisible branches not just to each other, but to our extinct relatives and our evolutionary ancestors."
In a poetic, personal talk, TED Fellow Katlego Kolanyane-Kesupile examines the connection between her modern queer lifestyle and her childhood upbringing in a rural village in Botswana. "In a time where being brown, queer, African and seen as worthy of space means being everything but rural, I fear that we're erasing the very struggles that got us to where we are now," she says. "Indigenizing my queerness means bridging the many exceptional parts of myself."
Robots are designed for speed and precision -- but their rigidity has often limited how they're used. In this illuminating talk, biomedical engineer Giada Gerboni shares the latest developments in "soft robotics," an emerging field that aims to create nimble machines that imitate nature, like a robotic octopus. Learn more about how these flexible structures could play a critical role in surgery, medicine and our daily lives.
Many artificial intelligence researchers expect AI to outsmart humans at all tasks and jobs within decades, enabling a future where we're restricted only by the laws of physics, not the limits of our intelligence. MIT physicist and AI researcher Max Tegmark separates the real opportunities and threats from the myths, describing the concrete steps we should take today to ensure that AI ends up being the best -- rather than worst -- thing to ever happen to humanity.
In this imaginative talk, neuroengineer Sam Rodriques takes us on a thrilling tour of the next 100 years in brain science. He envisions strange (and sometimes frightening) innovations that may be the key to understanding and treating brain disease -- like lasers that drill tiny holes in our skulls and allow probes to study the electrical activity of our neurons.
In her brutally honest, ironically funny and widely read meditation on death, "You May Want to Marry My Husband," the late author and filmmaker Amy Krouse Rosenthal gave her husband Jason very public permission to move on and find happiness. A year after her death, Jason offers candid insights on the often excruciating process of moving through and with loss -- as well as some quiet wisdom for anyone else experiencing life-changing grief.
Our leaders and institutions are failing us, but it's not always because they're bad or unethical, says venture capitalist John Doerr -- often, it's simply because they're leading us toward the wrong objectives. In this practical talk, Doerr shows us how we can get back on track with "Objectives and Key Results," or OKRs -- a goal-setting system that's been employed by the likes of Google, Intel and Bono to set and execute on audacious goals. Learn more about how setting the right goals can mean the difference between success and failure -- and how we can use OKRs to hold our leaders and ourselves accountable.
What will we find in the twilight zone: the vast, mysterious, virtually unexplored realm hundreds of meters below the ocean's surface? Heidi M. Sosik of Woods Hole Oceanographic Institution wants to find out. In this wonder-filled talk, she shares her plan to investigate these uncharted waters, which may hold a million new species and 90 percent of the world's fish biomass, using submersible technology. What we discover there won't just astound us, Sosik says -- it will help us be better stewards of the world's oceans. (This ambitious idea is part of the Audacious Project, TED's initiative to inspire and fund global change.)
When facts are false, decisions are wrong, says editor and TED Fellow Olga Yurkova. To stop the spread of fake news, she and a group of journalists launched StopFake.org, which exposes biased or inaccurate reporting in order to rebuild the trust we've lost in our journalists, leaders and institutions. Learn more about the fight against misinformation as well as two critical ways we can ensure we're not reading (or sharing) fake news.
What if we could save the fishing industry and protect the ocean at the same time? Marine ecologist Enric Sala shares his bold plan to safeguard the high seas -- some of the last wild places on earth, which fall outside the jurisdiction of any single country -- by creating a giant marine reserve that covers two-thirds of the world's ocean. By protecting the high seas, Sala believes we will restore the ecological, economic and social benefits of the ocean. "When we can align economic needs with conservation, miracles can happen," Sala says.
Can technology make people safer from threats like violent extremism, censorship and persecution? In this illuminating talk, technologist Yasmin Green details programs pioneered at Jigsaw (a unit within Alphabet Inc., the collection of companies that also includes Google) to counter radicalization and online harassment -- including a project that could give commenters real-time feedback about how their words might land, which has already increased spaces for dialogue. "If we ever thought that we could build an internet insulated from the dark side of humanity, we were wrong," Green says. "We have to throw our entire selves into building solutions that are as human as the problems they aim to solve."
