A new weapon in the fight against superbugs | David Brenner

vor 3 Stunden 3 Minuten
Since the widespread use of antibiotics began in the 1940s, we've tried to develop new drugs faster than bacteria can evolve -- but this strategy isn't working. Drug-resistant bacteria known as superbugs killed nearly 700,000 people last year, and by 2050 that number could be 10 million -- more than cancer kills each year. Can physics help? In a talk from the frontiers of science, radiation scientist David Brenner shares his work studying a potentially life-saving weapon: a wavelength of ultraviolet light known as far-UVC, which can kill superbugs safely, without penetrating our skin. Followed by a Q&A with TED Curator Chris Anderson.

Success stories from Kenya's first makerspace | Kamau Gachigi

Dezember 13, 2017 - 16:02
Africa needs engineers, but its engineering students often end up working at auditing firms and banks. Why? Kamau Gachigi suspects it's because they don't have the spaces and materials needed to test their ideas and start businesses. To solve this problem, Gachigi started Gearbox, a makerspace and hardware accelerator that provides a rapid prototyping environment for both professionals and people with no formal engineering background. In this forward-thinking talk, he shares some of the extraordinary projects and innovations coming out of his Kenyan fab lab.

Lessons from a solar storm chaser | Miho Janvier

Dezember 12, 2017 - 15:00
Space physicist Miho Janvier studies solar storms: giant clouds of particles that escape from the Sun and can disrupt life on Earth (while also producing amazing auroras). How do you study the atmosphere on the Sun, which burns at temperatures of up to around 10 million degrees Kelvin? With math! Join the TED Fellow as she shares her work trying to better understand how the Sun affects us here on Earth.

A bold plan to house 100 million people | Gautam Bhan

Dezember 11, 2017 - 15:00
Mumbai, Delhi, Chennai, Kolkata -- all the major cities across India, have one great thing in common: they welcome people arriving in search of work. But what lies at the other end of such openness and acceptance? Sadly, a shortage of housing for an estimated 100 million people, many of whom end up living in informal settlements. Gautam Bhan, a human settlement expert and researcher, is boldly reimagining a solution to this problem. He shares a new vision of urban India where everyone has a safe, sturdy home.

Adventures of an interplanetary architect | Xavier De Kestelier

Dezember 11, 2017 - 13:00
How will we live elsewhere in the galaxy? On Earth, natural resources for creating structures are abundant, but sending these materials up with us to the Moon or Mars is clunky and cost-prohibitive. Enter architect Xavier De Kestelier, who has a radical plan to use robots and space dust to 3D print our interplanetary homes. Learn more about the emerging field of space architecture with this fascinating talk about the (potentially) not-too-distant future.

The secret language of letter design | Martina Flor

Dezember 5, 2017 - 15:00

In a warm, personal talk, he shares his effort to reconcile who he is with who the world tells him a man should be. And he has a challenge for men: "See if you can use the same qualities that you feel make you a man to go deeper," Baldoni says. "Your strength, your bravery, your toughness: Are you brave enough to be vulnerable? Are you strong enough to be sensitive? Are you confident enough to listen to the women in your life?"

A Republican mayor's plan to replace partisanship with policy | G.T. Bynum

November 30, 2017 - 15:00
Conventional wisdom says that to win an election, you need to play to your constituencies' basest, most divisive instincts. But as a candidate for mayor of Tulsa, Oklahoma, G.T. Bynum decided to skip the smear campaigns and trash talk and instead focus on results. He told Tulsa's voters exactly what he wanted to accomplish if elected and gave them transparent ways to measure his success, and it led him to win the election. In a hopeful, funny talk, Bynum shares how he's now using data and evaluation to tackle his city's most pressing issues -- and why we need to set aside our philosophical disagreements and focus on those aspirations that unite us.

Fashion has a pollution problem -- can biology fix it? | Natsai Audrey Chieza

November 29, 2017 - 16:01
Natsai Audrey Chieza is a designer on a mission -- to reduce pollution in the fashion industry while creating amazing new things to wear. In her lab, she noticed that the bacteria Streptomyces coelicolor makes a striking red-purple pigment, and now she's using it to develop bold, color-fast fabric dye that cuts down on water waste and chemical runoff, compared with traditional dyes. And she isn't alone in using synthetic biology to redefine our material future; think -- "leather" made from mushrooms and superstrong yarn made from spider-silk protein. We're not going to build the future with fossil fuels, Chieza says. We're going to build it with biology.

What makes our bodies age ... our skin wrinkle, our hair turn white, our immune systems weaken? Biologist Elizabeth Blackburn shares a Nobel Prize for her work finding out the answer, with the discovery of telomerase: an enzyme that replenishes the caps at the end of chromosomes, which break down when cells divide.
