First life with 'alien' DNA
An engineered bacterium is able to copy DNA that contains unnatural genetic letters.
For billions of years, the history of life has been written with just four letters — A, T, C and G, the labels given to the DNA subunits contained in all organisms. That alphabet has just grown longer, researchers announce, with the creation of a living cell that has two 'foreign' DNA building blocks in its genome.
“What we have now is a living cell that literally stores increased genetic information,” says Floyd Romesberg, a chemical biologist at the Scripps Research Institute in La Jolla, California, who led the 15-year effort. Their research appears online today in Nature1.

What could possibly go wrong? I sense a premise for some new sci-fi/horror scripts. Let's hope it goes no further than that.
In what is being called a major scientific breakthrough, researchers at the Scripps Research Institute say they created the first microbes containing artificial DNA. It could not only alter the basic genetic code, the fundamental building blocks of life, but also lead to new drugs and treatments.

well,now youze done it:
The creation of life
The first living organism to carry and pass down to future generations an expanded genetic code has been created by American scientists, paving the way for a host of new life forms whose cells carry synthetic DNA that looks nothing like the normal genetic code of natural organisms.

Nothing could possibly go wrong with people creating entirely new species of bacterium and viruses...containing designer DNA strands...for which no human would have antibodies...nothing at all.
