Using robotics, laser rangefinders, GPS and smart feedback tools, Dennis Hong is building a car for drivers who are blind. It's not a "self-driving" car, he's careful to note, but a car in which a non-sighted driver can determine speed, proximity and route- and drive independently. [9:09]

How can animation convey complex, intangible concepts? A visual metaphor, or an idea represented through imagery, can take an idea as massive as Big Data and tie it to the familiar depiction of a growing tree. TED-Ed animators explain how to make an abstract idea come alive visually. [5:03]

There's been a lot of talk and research interest around the possibility of resurrecting certain organisms (or, at least their genomes) from extinction, with Woolly Mammoths being prime candidates for such an endeavor. But what about a closely related group, like the Mastodons? What's the criteria for possible 'de-extinction'? The Brain Scoop takes a look. [3:57]
