Talk of the week Daniel Levitin: How to stay calm when you know you'll be stressed 12:20 minutes · Filmed Sep 2015 · Posted Oct 2015 · TEDGlobal>London You're not at your best when you're stressed. In fact, your brain has evolved over millennia to release cortisol in stressful situations, inhibiting rational, logical thinking but potentially helping you survive, say, being attacked by a lion. Neuroscientist Daniel Levitin thinks there's a way to avoid making critical mistakes in stressful situations, when your thinking becomes clouded -- the pre-mortem. "We all are going to fail now and then," he says. "The idea is to think ahead to what those failures might be." Watch now »

More from TED.com Cesar Harada moved his science class into an industrial mega-space where imaginative kids work with wood, metal, chemistry, biology, optics and, occasionally, power tools to build cool new projects with a purpose: solving the threats facing the world's oceans. There, he instills a universal lesson that his own parents taught him: "You can make a mess, but you have to clean up after yourself." Watch » In this wonderful talk, artist Christine Sun Kim, who is deaf, invites us to open our eyes and ears and participate in the rich treasure of visual language. She shows us how sound doesn't have to be known solely through the ears -- it can be felt, seen and experienced as an idea. Watch » In 2013, the world learned how the NSA and GCHQ spied on the German government through rooftop antennas. And Mathias Jud and Christoph Wachter thought: Well, if they're listening ... let's talk to them. Mounting their own antennas on the roof of the Swiss Embassy, they set up an open network that let the world send messages to US and UK spies listening nearby. It's one of three bold, often funny, and frankly subversive projects in this talk, which challenges surveillance and closed networks. Watch » When a family falls into crisis -- thanks to unemployment, drugs, bad relationships, bad luck -- the social services system is supposed to help them get back on track. In the UK, a typical family in crisis is eligible for services from more than 70 different agencies -- yet it's unlikely that any one of them can really make a difference, says Hillary Cottam. She asks us: How can we help the helpers? Watch »

Quote of the Week “ I propose that we can use psychology to solve problems that we didn't even realize were problems at all. This is my suggestion for getting people to finish their course of antibiotics: Don't give them 24 white pills. Give them 18 white pills and six blue ones and tell them to take the white pills first and then take the blue ones. It's called chunking. The likelihood that people will get to the end is much greater when there is a milestone somewhere in the middle." Rory Sutherland Perspective is everything

Talk of the week Jennifer Doudna: We can now edit our DNA. But let's do it wisely 15:53 minutes · Filmed Sep 2015 · Posted Oct 2015 · TEDGlobal>London Jennifer Doudna is co-inventor of a groundbreaking new technology for editing genes. The tool, referred to as CRISPR-Cas9, allows scientists to make precise edits to DNA strands. It could lead to treatments for genetic diseases … but could also be used to create so-called "designer babies." Doudna clearly explains how CRISPR-Cas9 works -- and then asks the scientific community to pause and discuss the ethics of this new tool. Watch now »

More from TED.com Cave explorer and geologist Francesco Sauro travels to the hidden continent under our feet, surveying deep, dark places inside the earth that humans have never been able to reach before. In the spectacular tepuis of South America, he finds new minerals and insects that have evolved in isolation. (And he uses his knowledge of these alien worlds to train astronauts to travel into equally isolated places.) Watch » Investigative journalist Will Potter is the only reporter who has been inside a Communications Management Unit, or CMU, within a US prison. These secret units change how prisoners are treated -- even preventing them from hugging their children. Potter, a TED Fellow, shows us who is imprisoned here, and how the government is trying to keep them hidden. "The message was clear," he says. "Don’t talk about this place." Watch » + Find sources for this talk at willpotter.com/cmu   Don't you love having access to all the information in the world? And yet, don't you kind of hate being glued to your screen all the time? Designer Tom Uglow imagines a future without screens -- in which our love for simple tools can coexist with our need for information and connection. "Reality is richer than screens," he says. "We can have a happy place filled with the information we love that feels as natural as switching on a light bulb." Watch » ICYMI: this classic TED Talk on the subject of race -- with a new lens to open the conversation. Because it can be touchy; as finance executive Mellody Hobson says, it's a "conversational third rail." But, she says, that's exactly why we need to start talking about it in smarter ways. In this engaging talk, Hobson makes the case that speaking openly about race -- and particularly about diversity in hiring -- makes for better business, better ideas and a better society. Watch »

Quote of the Week “ The role of a teacher is to facilitate learning. That's it. But the dominant culture of education has come to focus on not learning, but testing. So in place of curiosity, what we have is a culture of compliance. Our children and teachers are encouraged to follow routine algorithms rather than to excite their power of imagination and curiosity."   Sir Ken Robinson How to escape from education's death valley
