The most detailed map of galaxies, black holes and stars ever made | Juna Kollmeier

6/7/2019
More
Humans have been studying the stars for thousands of years, but astrophysicist Juna Kollmeier is on a special mission: creating the most detailed 3-D maps of the universe ever made. Journey across the cosmos as she shares her team's work on the Sloan Digital Sky Survey, imaging millions of stars, black holes and galaxies in unprecedented detail. If we maintain our pace, she says, we can map every large galaxy in the observable universe by 2060. "We've gone from arranging clamshells to...

What it takes to launch a telescope | Erika Hamden

5/30/2019
More
TED Fellow and astronomer Erika Hamden leads the team building FIREBall, a telescope that hangs from a giant balloon at the very edge of space and looks for clues about how stars are created. She takes us inside the roller-coaster, decade-long journey to get the telescope from an idea into orbit -- and shows how failure is inevitable when you're pushing the limits of knowledge.

Can we cure genetic diseases by rewriting DNA? | David R. Liu

4/23/2019
More
In a story of scientific discovery, chemical biologist David R. Liu shares a breakthrough: his lab's development of base editors that can rewrite DNA. This crucial step in genome editing takes the promise of CRISPR to the next level: if CRISPR proteins are molecular scissors, programmed to cut specific DNA sequences, then base editors are pencils, capable of directly rewriting one DNA letter into another. Learn more about how these molecular machines work -- and their potential to treat or...

Wearable tech that helps you navigate by touch | Keith Kirkland

4/10/2019
More
Keith Kirkland is developing wearable tech that communicates information using only the sense of touch. He's trying to figure out: What gestures and vibration patterns could intuitively communicate ideas like "stop" or "go"? Check out his team's first product, a navigation device for the blind and visually impaired, and learn more about the entirely new "haptic language" he's creating to power it.

How to keep human bias out of AI | Kriti Sharma

3/15/2019
More
AI algorithms make important decisions about you all the time -- like how much you should pay for car insurance or whether or not you get that job interview. But what happens when these machines are built with human bias coded into their systems? Technologist Kriti Sharma explores how the lack of diversity in tech is creeping into our AI, offering three ways we can start making more ethical algorithms.

The self-assembling computer chips of the future | Karl Skjonnemand

2/27/2019
More
The transistors that power the phone in your pocket are unimaginably small: you can fit more than 3,000 of them across the width of a human hair. But to keep up with innovations in fields like facial recognition and augmented reality, we need to pack even more computing power into our computer chips -- and we're running out of space. In this forward-thinking talk, technology developer Karl Skjonnemand introduces a radically new way to create chips. "This could be the dawn of a new era of...

How do we learn to work with intelligent machines? | Matt Beane

2/4/2019
More
The path to skill around the globe has been the same for thousands of years: train under an expert and take on small, easy tasks before progressing to riskier, harder ones. But right now, we're handling AI in a way that blocks that path -- and sacrificing learning in our quest for productivity, says organizational ethnographer Matt Beane. What can be done? Beane shares a vision that flips the current story into one of distributed, machine-enhanced mentorship that takes full advantage of AI's...

How to be "Team Human" in the digital future | Douglas Rushkoff

12/13/2018
More
Humans are no longer valued for our creativity, says media theorist Douglas Rushkoff -- in a world dominated by digital technology, we're now just valued for our data. In a passionate talk, Rushkoff urges us to stop using technology to optimize people for the market and start using it to build a future centered on our pre-digital values of connection, creativity and respect. "Join 'Team Human.' Find the others," he says. "Together let's make the future that we always wanted."
