The same family of chemical signals that attracts developing sensory nerves up the spinal cord toward the brain serves to repel motor nerves, sending them in the opposite direction, down the cord and away from the brain, report researchers at the University of Chicago in the September 2005 issue of Nature Neuroscience (available online August 14). The finding may help physicians restore function to people with paralyzing spinal cord injuries. [Medical News Today]

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]
