Image of the Week: Bacteria and Lightbulbs

Three enterprising students from the University of Wisconsin, Madison are trying to create a light bulb powered entirely by E.coli. “But, wait!” You might say. “E.coli doesn’t bioluminesce!” In order to overcome this slight hurdle, the students plan on inserting a strip of DNA into the bacteria’s genome which will enable the bug to glow in the dark. The light bulb itself will contain the modified bacteria, the necessary growth medium, and a set of specific microbes capable of recycling light to provide nutrients and eliminate waste – all of which together would produce a bulb which glows without electricity, aptly dubbed Biobulb (pictured below).
