Silicon Valley breeds the kind of people that create computers that fit in the palm of our hands, electric cars that can go hundreds of miles on a single charge and plans to launch tiny satellites across the globe to bring everyone in the world Internet access.
Biotechnology is now taking shape alongside those other big ideas, thanks to reduced costs in robotics, machine learning and some innovative Silicon Valley thinkers. Investors poured more than $3.9 billion into U.S. life sciences in 2014, and there are a growing number of startups in the field.
