Aren't these (http://www.washingtonpost.com/wp-dyn/content/article/2008/01/24/AR2008012402203.html?hpid=sec-health) guys just a tad bit behind the times? I mean, the world is already full of people who are artificial. Compared to that, fake microbes are small potatoes.
Scientists in Maryland yesterday said they had built from scratch an entire microbial chromosome, a loop of synthetic DNA carrying all the instructions that a simple cell needs to live and reproduce.
The feat marks the first time that anyone has made such a large strand of hereditary material from off-the-shelf chemical ingredients. Previous efforts had yielded DNA strands less than one-twentieth the size, and those pieces lacked many of the key biological programs that tell a cell how to stay alive.
On the basis of earlier experiments, the researchers believe the new, full-length loop would spontaneously "boot up" inside a cell, just as a downloaded operating system can awaken a computer -- a potentially historic event that would amount to the creation of the first truly artificial life form.
