Harvard's Pamela Silver is studying cyanobacteria to figure out how to use them to produce fuel, but also for "a more fantastical use," reports Technology Review's blog. As Silver reported at a recent conference, her team inserted cyanobacteria that was labeled fluorescently into zebrafish embryos and watched the fish — and bacteria — grow. "When we put E. coli into fish, they blew up, but they are extremely tolerant of cynabacteria," Silver said, according to Tech Review.
