Meet the next generation of world changers.

MIT Tech Review revealed its 35 Innovators Under 35 today, highlighting disruptors and advanced thinkers in a variety of fields. The science- and tech-focused list included several winners in the health and medicine fields, plus a few people innovating in rapidly expanding fields like drones and artificial intelligence.

It also includes an inventor who happens to combine those last two: Adam Bry, co-founder of Skydio, is building a consumer-focused drone that operates autonomously and can safely navigate around trees and people.

Oriol Vinyals, currently a Google DeepMind employee, developed artificial intelligence that allows a computer to accurately write descriptions of images. The technology is now being used to caption photos throughout the web and improve Google's image search.

Muyinatu Bell, a doctor at Johns Hopkins, invented a machine that produces clearer ultrasound images and increases the likelihood of detecting cancer in its early stages. The system is especially useful for obese patients, since fat tissue can distort ultrasound waves.

Several of the problems solved are environmental ones: USC assistant professor Kelly Sanders came up with a system (about which she briefed Congress) that better analyzes and helps regulate how much water is consumed by power plants. And Kenra Kuhl, co-founder of scientific tech startup Opus 12, created a reactor that turns carbon dioxide into chemicals that can be safely reused by scientists.

Other winners include Alex Hegyi, who invented an advanced consumer camera that detects things like counterfeit drugs and spoiled food, and Ronaldo Tenório, who created an app that acts as a sign language translator--and has already been downloaded by one in 10 deaf people in his native Brazil.

This is MIT Tech Review's 16th annual list. Nominees go through an application process and are chosen by a panel of judges that includes experts from around the world and some of the magazine's editors.
