“Glow little glow worm, glitter, glitter”, or so goes the old familiar song.  Now it appears this little ditty is fast becoming a reality for researchers at Oak Ridge National Laboratory, who have recently developed their own version of a glow worm that may help solve the problem of cleaning up toxic waste.  According to Science News, scientists have genetically engineered a new form of bacterium known as p. florescens.  This bacterium, which is created from a luminescent marine counterpart, has the peculiar feature of lighting up when it munches on hazardous waste.  Since recent field tests have proven successful, maybe it won’t be long until the scientists are also singing “you light up my life.”
