Meet the youngest-ever mayor in Japan's history | Ryosuke Takashima
TED Fellow Ryosuke Takashima is the youngest-ever mayor in Japan's history — but he doesn't consider himself a politician. His approach to leadership is simple: listen to as many voices as possible (from students to elders) in order to figure out what needs fixing. Hear why he thinks inviting citizens to participate in reforming their own communities is the best way to get things done.

The gravity-defying future of manufacturing | Schendy Kernizan
3D printing promised to reinvent how we make things, but it's mostly stuck producing prototypes with a high level of waste. Designer and TED Fellow Schendy Kernizan found a different way — by printing objects directly into a tub of gel. He explains how this technique eliminates the constraints of gravity, pushing the limits of how we can manufacture objects across medicine, fashion, space travel and more.

What's In The Air We Breathe
2017 has seen Indian metros take the title of cities with the worst air quality, with Delhi, the national capital, closing down schools and offices for a week. Dr. Sarath Guttikunda talks about what causes a worsening in air quality and how to deal with it ranging from green solutions to making diamonds from dust in the air. We also get to meet his comic avatar at http://urbanemissions.blogspot.in/2009/04/you-want-me-to-walk-cartoon-by.html

The untapped genius that could change science for the better | Jedidah Isler
Jedidah Isler dreamt of becoming an astrophysicist since she was a young girl, but the odds were against her: At that time, only 18 black women in the United States had ever earned a PhD in a physics-related discipline. In this personal talk, she shares the story of how she became the first black woman to earn a PhD in astrophysics from Yale -- and her deep belief in the value of diversity to science and other STEM fields. "Do not think for one minute that because you are who you are, you cannot be who you imagine yourself to be," she says. "Hold fast to those dreams and let them carry you into a world you can't even imagine."

The real-life superheroes helping Syrian refugees
Society has a set of stories it tells itself about who refugees are and what they look like, says documentarian and TED Fellow Feras Fayyad. With his films, he's on a mission to separate the facts about refugees from fiction, as a form of resistance -- for himself, his daughter and the millions of other Syrian refugees across the world. A harrowing account, a quest to end injustice and a testament to the power of storytelling.

How hip-hop helps us understand science | Danielle N. Lee
In the early 1990s, a scandal rocked evolutionary biology: scientists discovered that songbirds -- once thought to be strictly monogamous -- engaged in what's politely called "extra-pair copulation." In this unforgettable biology lesson on animal infidelity, TED Fellow Danielle N. Lee shows how she uses hip-hop to teach science, leading the crowd in an updated version of Naughty by Nature's hit "O.P.P." Hosted on Acast. See acast.com/privacy for more information.

Why violence is rising with global temperatures | Peter Schwartzstein
Climate change doesn't just melt ice caps, it also fuels conflict, corruption and division worldwide, explains TED Fellow and journalist Peter Schwartzstein. From droughts in Syria to rising seas in Bangladesh, he explores how climate stress escalates existing social instabilities — and underscores why every effort to curb a warming world matters, no matter how small.

Medical tech designed to meet Africa's needs | Soyapi Mumba
In sub-Saharan Africa, power outages, low technology penetration, slow internet and understaffed hospitals plague health care systems. To make progress on these problems in Malawi, TED Fellow Soyapi Mumba and his team created a new system from scratch -- from the software that powers their electronic health records to the infrastructure used to support it. In this quick, hopeful talk, Mumba shares how his jack-of-all-trades mindset can help reshape health care in low-resource environments.

Why are these 32 symbols found in ancient caves all over Europe?
Written language, the hallmark of human civilization, didn't just suddenly appear one day. Thousands of years before the first fully developed writing systems, our ancestors scrawled geometric signs across the walls of the caves they sheltered in. Paleoanthropologist, rock art researcher and TED Senior Fellow Genevieve von Petzinger has studied and codified these ancient markings in caves across Europe. The uniformity of her findings suggest that graphic communication, and the ability to preserve and transmit messages beyond a single moment in time, may be much older than we think.

How community-led research drives social change
What's the best way to develop and implement solutions to social problems? TED Fellow and human rights activist Monica Malta discusses why traditional, top-down policymaking often fails by excluding key voices and missing root causes. She shows why community-based participatory research — a method that empowers communities to co-create solutions to their own challenges — taps into the resilience and strength of everyday people to be leaders of change.

Simple Artificial Brains to Govern Complex Tasks
A 1mm-long nematode worm is the world’s best understood animal and with a simple brain of only 302 nerve cells, it can produce complex behavior that current artificial intelligence (AI) systems cannot. Ramin and his team is investigating the nervous system of the C. elegans worm from a machine learning perspective, as an ideal instance of the Simplexity concept, to create simple and transparent AI agents for the control of complex tasks. More information on http://www.tedxvienna.at Ramin is a PhD research assistant in Computer Science at TU Wien, Austria, where he works on developing interpretable artificial intelligence (AI) algorithms for real-world applications. By bringing insights from neuroscience to machine learning he is improving the functional transparency and robustness of AI systems. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
