In May, researchers from the J. Craig Venter Institute a not-for-profit, genomic- focused basic research organization, reported the successful construction of a first self-replicating, synthetic bacterial cell. They copied and modified an entire genome of a small bacterial cell, inserted it into a living cell of another species, and by doing so created a new, synthetic organism.

«This is the first self-replicating species that we’ve had on the planet whose parent is a computer,» U.S. scientist Craig Venter who led the team said. «It also is the first species to have its own website encoded in its genetic code.» Scientists hope to patent the organism called Mycoplasma laboratorium and engineer it to manufacture cheap biofuels, medicines and other useful compounds.

However, critics argue the move will stifle future science relying on an artificial microbes. U.S. President Obama has asked the Presidential Commission for the Study of Bioethical Issues to study the implications of synthetic biology after proponent, however, no federal regulations has been issued yet.
