You Never Have to Eat, But You Have a Greenish Tinge

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. The zebrafish didn't get enough energy from the cyanobacteria to survive without other energy sources, but the researchers are working on that.
