15-year-old Indian-American Gitanjali Rao, a "brilliant" young scientist and inventor, has been named by TIME magazine as the first-ever 'Kid of the Year' for her "astonishing work" using technology to tackle issues ranging from contaminated drinking water to opioid addiction and cyberbullying.

"The world belongs to those who shape it. And however uncertain that world may feel at a given moment, the reassuring reality seems to be that each new generation produces more of what these kids have already achieved: positive impact, in all sizes," Time said.
