Andy Yen: Think your email's private? Think again


Sending an email message is like sending a postcard, says scientist Andy Yen in this thought-provoking talk: Anyone can read it. Yet encryption, the technology that protects the privacy of email communication, does exist. It's just that until now it has been difficult to install and a hassle to use. Showing a demo of an email program he designed with colleagues at CERN, Yen argues that encryption can be made simple to the point of becoming the default option, providing true email privacy to all.

Jon Gosier: The problem with "trickle-down techonomics"


Hooray for technology! It makes everything better for everyone!! Right? Well, no. When a new technology, like ebooks or health trackers, is only available to some people, it has unintended consequences for all of us. Jon Gosier, a TED Fellow and tech investor, calls out the idea of "trickle-down techonomics," and shares powerful examples of how new tech can make things actually worse if it's not equally distributed. As he says, "the real innovation is in finding ways to include everyone."

In some parts of the world, half of the women lack basic reading and writing skills. The reasons vary, but in many cases, literacy isn't valued by fathers, husbands, even mothers.

Guy Winch: Why we all need to practice emotional first aid


We'll go to the doctor when we feel flu-ish or a nagging pain. So why don’t we see a health professional when we feel emotional pain: guilt, loss, loneliness? Too many of us deal with common psychological-health issues on our own, says Guy Winch. But we don’t have to. He makes a compelling case to practice emotional hygiene — taking care of our emotions, our minds, with the same diligence we take care of our bodies.

How do vaccines prevent disease -- even among people too young to get vaccinated?

Marc Kushner: Why the buildings of the future will be shaped by ... you


"Architecture is not about math or zoning -- it's about visceral emotions," says Marc Kushner. In a sweeping — often funny — talk, he zooms through the past thirty years of architecture to show how the public, once disconnected, have become an essential part of the design process. With the help of social media, feedback reaches architects years before a building is even created. The result? Architecture that will do more for us than ever before.

Jaap de Roode: How butterflies self-medicate


Just like us, the monarch butterfly sometimes gets sick thanks to a nasty parasite. But biologist Jaap de Roode noticed something interesting about the butterflies he was studying — infected female butterflies would choose to lay their eggs on a specific kind of plant that helped their offspring avoid getting sick. How do they know to choose this plant? Think of it as “the other butterfly effect” — which could teach us to find new medicines for the treatment of human disease.

Today, a single email can launch a worldwide movement. But as sociologist Zeynep Tufekci suggests, even though online activism is easy to grow, it often doesn't last. Why?

TEDxCanberra

Khadija Gbla: My mother’s strange definition of empowerment


Khadija Gbla grew up caught between two definitions of what it means to be an “empowered woman.” While her Sierra Leonean mother thought that circumsizing her — and thus stifling her sexual urges — was the ultimate form of empowerment, her culture as a teenager in Australia told her that she deserved pleasure and that what happened to her was called “female genital mutilation.” In a candid and funny talk, she shares what it was like to make her way in a “clitoris-centric society,” and how she works to make sure other women don’t have to figure this out. (Warning: This talk contains hard-to-hear details.)

Severine Autesserre: To solve mass violence, look to locals


Severine Autesserre studies the Democratic Republic of Congo, which is in the middle of the deadliest conflict since World War II; it's been called "the largest ongoing humanitarian crisis in the world.” The conflict seems hopelessly, unsolvably large. But her insight from decades of listening and engaging: The conflicts are often locally based. And instead of focusing on solutions that scale to a national level, leaders and aid groups might be better served solving local crises before they ignite.

Miguel Nicolelis: Brain-to-brain communication has arrived. How we did it


You may remember neuroscientist Miguel Nicolelis — he built the brain-controlled exoskeleton that allowed a paralyzed man to kick the first ball of the 2014 World Cup. What’s he working on now? Building ways for two minds (rats and monkeys, for now) to send messages brain to brain. Watch to the end for an experiment that, as he says, will go to "the limit of your imagination."

Morgana Bailey: The danger of hiding who you are


Morgana Bailey has been hiding her true self for 16 years. In a brave talk, she utters four words that might not seem like a big deal to some, but to her have been paralyzing. Why speak up?

In front of an audience of her co-workers, she reflects on what it means to fear the judgment of others, and how it makes us judge ourselves.
