Meet the youngest-ever mayor in Japan's history | Ryosuke Takashima

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.

How we use astrophysics to study earthbound problems
To study a system as complex as the entire universe, astrophysicists need to be experts at extracting simple solutions from large data sets. What else could they do with this expertise? In an interdisciplinary talk, TED Fellow and astrophysicist Federica Bianco explains how she uses astrophysical data analysis to solve urban and social problems -- as well as stellar mysteries.

How a handful of fishing villages sparked a marine conservation revolution | Alasdair Harris
We need a radically new approach to ocean conservation, says marine biologist Alasdair Harris. In a visionary talk, he lays out a surprising solution to the problem of overfishing that could both revive marine life and rebuild local fisheries -- all by taking less from the ocean. “When we design it right, marine conservation reaps dividends that go far beyond protecting nature,” he says.

But they also pose safety risks and accessibility issues for many of their passengers, especially women. Bringing a feminist perspective, activist and TED Fellow Naomi Mwaura calls for a revolution in public transportation by making routes transparent, protecting passengers from harassment and paving a career path for women in the industry.

Could tissue engineering mean personalized medicine?
Each of our bodies is utterly unique, which is a lovely thought until it comes to treating an illness -- when every body reacts differently, often unpredictably, to standard treatment. Tissue engineer Nina Tandon talks about a possible solution: Using pluripotent stem cells to make personalized models of organs on which to test new drugs and treatments, and storing them on computer chips. (Call it extremely personalized medicine.)

Play with smart materials
Ink that conducts electricity; a window that turns from clear to opaque at the flip of a switch; a jelly that makes music. All this stuff exists, and Catarina Mota says: It's time to play with it. Mota leads us on a tour of surprising and cool new materials, and suggests that the way we'll figure out what they're good for is to experiment, tinker and have fun.

The secret US prisons you've never heard of before
Investigative journalist Will Potter is the only reporter who has been inside a Communications Management Unit, or CMU, within a US prison. These units were opened secretly, and radically alter 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."

Everyone deserves to be safe
What does a woman never leave home without? A safety pin, a pointed nail file, red chili powder -- some small weapon to fight off unwanted touches and grabs in public. When artist Jasmeen Patheja asked women to share this intimate detail of their lives, it made her point: everyone deserves safety. Her project, Blank Noise, helps to reclaim public safety for everyone through public projects that build trust and independence for everyone. Watch to the end for a thoughtful dialogue with host Shah Rukh Khan.
