A delightful way to teach kids about computers | Linda Liukas

Computer code is the next universal language, and its syntax will be limited only by the imaginations of the next generation of programmers. Linda Liukas is helping to educate problem-solving kids, encouraging them to see computers not as mechanical, boring and complicated but as colorful, expressive machines meant to be tinkered with. In this talk, she invites us to imagine a world where the Ada Lovelaces of tomorrow grow up to be optimistic and brave about technology and use it to create a new world that is wonderful, whimsical and a tiny bit weird.

Our campaign to ban plastic bags in Bali | Melati and Isabel Wijsen

Plastic bags are essentially indestructible, yet they're used and thrown away with reckless abandon. Most end up in the ocean, where they pollute the water and harm marine life; the rest are burned in garbage piles, where they release harmful dioxins into the atmosphere. Melati and Isabel Wijsen are on a mission to stop plastic bags from suffocating their beautiful island home of Bali. Their efforts -- including petitions, beach cleanups, even a hunger strike -- paid off when they convinced their governor to commit to a plastic bag-free Bali by 2018.

A robot that runs and swims like a salamander | Auke Ijspeert

Roboticist Auke Ijspeert designs biorobots, machines modeled after real animals that are capable of handling complex terrain and would appear at home in the pages of a sci-fi novel. The process of creating these robots leads to better automata that can be used for fieldwork, service, and search and rescue. But these robots don't just mimic the natural world -- they help us understand our own biology better, unlocking previously unknown secrets of the spinal cord.

How I took on the gene patent industry -- and won | Tania Simoncelli

Are human genes patentable? Back in 2005, when Tania Simoncelli first contemplated this complex question, US patent law said they were -- which meant patent holders had the right to stop anyone from sequencing, testing or even looking at a patented gene. Troubled by the way this law both harmed patients and created a barrier to biomedical innovation, Simoncelli and her colleagues at the ACLU challenged it. In this riveting talk, hear the story of how they took a case everybody told them they would lose all the way to the Supreme Court.

Glow-in-the-dark sharks and other stunning sea creatures | David Gruber

Just a few meters below the waves, marine biologist and explorer-photographer David Gruber discovered something amazing -- a surprising new range of sea creatures that glow in many colors in the ocean's dim blue light. Join his journey in search of biofluorescent sharks, seahorses, sea turtles and more, and learn how these light-up creatures could illuminate a new understanding of our own brains.

Capitalism will eat democracy -- unless we speak up | Yanis Varoufakis

Have you wondered why politicians aren't what they used to be, why governments seem unable to solve real problems? Economist Yanis Varoufakis, the former Minister of Finance for Greece, says that it's because you can be in politics today but not be in power -- because real power now belongs to those who control the economy. He believes that the mega-rich and corporations are cannibalizing the political sphere, causing financial crisis.

The unheard story behind the Sistine Chapel | Elizabeth Lev

The Sistine Chapel is one of the most iconic buildings on earth -- but there's a lot you probably don't know about it. In this tour-de-force talk, art historian Elizabeth Lev guides us across the famous building's ceiling and Michelangelo's vital depiction of traditional stories, showing how the painter reached beyond the religious iconography of the time to chart new artistic waters. Five hundred years after the artist painted it, says Lev, the Sistine Chapel forces us to look around as if it were a mirror and ask, "Who am I, and what role do I play in this great theater of life?"

How I turned a deadly plant into a thriving business | Achenyo Idachaba

The water hyacinth may look like a harmless, even beautiful flowering plant -- but it's actually an invasive aquatic weed that clogs waterways, stopping trade, interrupting schooling and disrupting everyday life. In this scourge, green entrepreneur Achenyo Idachaba saw opportunity. Follow her journey as she turns weeds into woven wonders.

Can a computer write poetry? | Oscar Schwartz

If you read a poem and feel moved by it, but then find out it was actually written by a computer, would you feel differently about the experience? Would you think that the computer had expressed itself and been creative, or would you feel like you had fallen for a cheap trick? In this talk, writer Oscar Schwartz examines why we react so strongly to the idea of a computer writing poetry -- and how this reaction helps us understand what it means to be human.

How we can make crops survive without water | Jill Farrant

As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land. Molecular biologist Jill Farrant studies a rare phenomenon that may help: "resurrection plants" -- super-resilient plants that seemingly come back from the dead. Could they hold promise for growing food in our coming hotter, drier world?
