The artificial muscles that will power robots of the future | Christoph Keplinger

Robot brains are getting smarter and smarter, but their bodies are often still clunky and unwieldy. Mechanical engineer Christoph Keplinger is designing a new generation of soft, agile robot inspired by a masterpiece of evolution: biological muscle. See these "artificial muscles" expand and contract like the real thing and reach superhuman speeds -- and learn how they could power prosthetics that are stronger and more efficient than human limbs.

How risk-taking changes a teenager's brain | Kashfia Rahman

Why do teenagers sometimes make outrageous, risky choices? Do they suddenly become reckless, or are they just going through a natural phase? To find out, Kashfia Rahman -- winner of the Intel International Science and Engineering Fair (and a Harvard freshman) -- designed and conducted an experiment to test how high school students respond to and get used to risk, and how it changes their still-developing brains. What she discovered about risk and decision-making could change how we think about why teens do what they do.

Wearable tech that helps you navigate by touch | Keith Kirkland

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.
