Aris Venetikidis: Making sense of maps


Map designer Aris Venetikidis is fascinated by the maps we draw in our minds as we move around a city -- less like street maps, more like schematics or wiring diagrams, abstract images of relationships between places. How can we learn from these mental maps to make better real ones? As a test case, he remakes the notorious Dublin bus map. (Filmed at TEDxDublin)

Thomas P. Campbell: Weaving narratives in museum galleries


As the director of the Metropolitan Museum of Art in New York, Thomas P. Campbell thinks deeply about curating—not just selecting art objects, but placing them in a setting where the public can learn their stories. With glorious images, he shows how his curation philosophy works for displaying medieval tapestries—and for the over-the-top fashion/art of Alexander McQueen. (From The Design Studio session at TED2012, guest-curated by Chee Pearlman and David Rockwell.)

TEDMED 2012

Ben Goldacre: What doctors don't know about the drugs they prescribe


When a new drug gets tested, the results of the trials should be published for the rest of the medical world -- except much of the time, negative or inconclusive findings go unreported, leaving doctors and researchers in the dark. In this impassioned talk, Ben Goldacre explains why these unreported instances of negative data are especially misleading and dangerous.

TEDxBoston 2012

Andrew McAfee: Are droids taking our jobs?


Robots and algorithms are getting good at jobs like building cars, writing articles, translating -- jobs that once required a human. So what will we humans do for work? Andrew McAfee walks through recent labor data to say: We ain't seen nothing yet. But then he steps back to look at big history, and comes up with a surprising and even thrilling view of what comes next. (Filmed at TEDxBoston.)

Read Montague: What we're learning from 5,000 brains


Mice, bugs and hamsters are no longer the only way to study the brain. Functional MRI (fMRI) allows scientists to map brain activity in living, breathing, decision-making human beings.

TEDGlobal 2012

Shimon Schocken: The self-organizing computer course


Shimon Schocken and Noam Nisan developed a curriculum for their students to build a computer, piece by piece. When they put the course online -- giving away the tools, simulators, chip specifications and other building blocks -- they were surprised that thousands jumped at the opportunity to learn, working independently as well as organizing their own classes in the first Massive Open Online Course (MOOC). A call to forget about grades and tap into the self-motivation to learn.

TEDGlobal 2012

Amy Cuddy: Your body language shapes who you are


Body language affects how others see us, but it may also change how we see ourselves. Social psychologist Amy Cuddy shows how “power posing” -- standing in a posture of confidence, even when we don’t feel confident -- can affect testosterone and cortisol levels in the brain, and might even have an impact on our chances for success.

Ellen Jorgensen: Biohacking -- you can do it, too


We have personal computing, why not personal biotech? That’s the question biologist Ellen Jorgensen and her colleagues asked themselves before opening Genspace, a nonprofit DIYbio lab in Brooklyn devoted to citizen science, where amateurs can go and tinker with biotechnology. Far from being a sinister Frankenstein's lab (as some imagined it), Genspace offers a long list of fun, creative and practical uses for DIYbio.

Julian Treasure: Why architects need to use their ears


Because of poor acoustics, students in classrooms miss 50 percent of what their teachers say and patients in hospitals have trouble sleeping because they continually feel stressed. Julian Treasure sounds a call to action for designers to pay attention to the “invisible architecture” of sound.

Sarah-Jayne Blakemore: The mysterious workings of the adolescent brain


Why do teenagers seem so much more impulsive, so much less self-aware than grown-ups? Cognitive neuroscientist Sarah-Jayne Blakemore compares the prefrontal cortex in adolescents to that of adults, to show us how typically “teenage” behavior is caused by the growing and developing brain.

TEDGlobal 2012

Susan Solomon: The promise of research with stem cells


Calling them "our bodies' own repair kits," Susan Solomon advocates research using lab-grown stem cells.

Scott Fraser: Why eyewitnesses get it wrong

TEDxUSC

Scott Fraser: Why eyewitnesses get it wrong


Scott Fraser studies how humans remember crimes -- and bear witness to them. In this powerful talk, which focuses on a deadly shooting at sunset, he suggests that even close-up eyewitnesses to a crime can create "memories" they could not have seen. Why? Because the brain abhors a vacuum. Editor's note: In the original version of this talk, Scott Fraser misspoke about available footage of Two World Trade Center (Tower 2). The misstatement has been edited out for clarity.

Vikram Patel: Mental health for all by involving all


Nearly 450 million people are affected by mental illness worldwide. In wealthy nations, just half receive appropriate care, but in developing countries, close to 90 percent go untreated because psychiatrists are in such short supply.

Shyam Sankar: The rise of human-computer cooperation


Brute computing force alone can’t solve the world’s problems.
