DNA Machine May Advance Genetic Sequencing for Patients

A new kind of machine for decoding DNA may help bring costs so low that it would be feasible to decode an individual’s DNA for medical reasons. The machine, developed by 454 Life Sciences of Branford, Conn., was used to resequence the genome of a small bacterium in four hours, its scientists report in an article published online today by the journal Nature.
In 1995, when the same bacterium was first sequenced, by Claire M. Fraser, it required 24,000 separate operations spread over four to six months, she said in an e-mail message. [New York Times]
