(Newser) – The first artificial life could be created within months as researchers emboldened by "species transplant" experiments prepare to insert synthetic genomes into a host bacterium, the Daily Telegraph reports.

One scientist likened the transformation to "changing a Macintosh computer into a PC by inserting a new piece of software." The team hopes to use the technology to engineer microorganisms capable of producing biofuels or eating toxic waste, but they acknowledge their research raises serious ethical questions and has the potential to launch a new generation of bioweapons.
