glowing bacterium

glowing bacterium glowing microbes clean up toxins

Researchers at the University of Aberdeen in Scotland have taken the gene that makes some marine life glow and inserted it into special bacteria. When those bugs are feeding on good soil, they emit a happy glow. But when the earth under them is a little toxic, the bacteria eventually go dark. Got a patch of suspect land? Sprinkle it with these bugs, watch them twinkle, and know where contamination begins.
