Lab Life

Where new life begins?
In true sci-fi fashion, a team of researchers from The Scripps Research Institute (TSRI) in La Jolla, Calif., has created a brand-new bacteria based on a genetic structure found nowhere on Earth.

According to lead researcher Floyd Romesberg, the feat involved artificially engineering a unique combination of DNA material -- a combination not found in any living creature -- and then successfully inserting it into a living cell that usually contains only natural combinations of DNA.

"Life on Earth in all its diversity is encoded by only two pairs of DNA bases, A-T and C-G," Romesberg explained in an institute news release. "And what we've made is an organism that stably contains those two plus a third, unnatural pair of bases."
