D. from Stanford and made his breakthrough almost immediately after starting his own lab in 2004, taking advantage of a 2002 discovery of light-sensitive proteins in green algae called channelrhodopsins.
He uses an improbable combination of green algae, blue lasers, gene therapy and fiber optics to map neural circuits deep inside the brain with a precision that has never been possible before.
We were surprised to learn that a biologist at the Argonne National Laboratory is transforming the data found in blue-green algae into music, while researchers at Michigan State discovered that super-strong bacteria can produce nuggets of gold.
The whole concept of creating a company built around the astounding properties of a variety of green algae called nannochloropsis smacks uncomfortably of the 1973 Charlton Heston flick Soylent Green, in which the namesake food product at the heart of the story is supposedly made from plankton but is actually made from spoiler alert!
