Innovators are changing our world as we know it. Their inventions open up a new area for others and achieves an innovation that lasts for decades.

Historic innovations contributed to human evolution in significant ways. They changed how we move, what we do and how fast we accomplish what we set out to do.

In recent times, young innovators are also contributing enormously to solve global issues to make our lives better.

The innovators listed below illustrate the most important emerging technologies of the moment. In biomedicine, for example, several people are figuring out in detail how the brain works and how we might stave off mental disorders.

Others are unearthing knowledge about cancer that might open new avenues for treatment. Meanwhile, as robotics and artificial intelligence make astonishing progress, innovators in those fields are showcased here. So are people who are cleverly taking advantage of the falling cost of sensors and bandwidth.

This is MIT Technology Review’s 35 under 35. They are young leaders developing new technologies to solve the major global challenges of today in remarkably different ways. Read their complete profiles here.
