A new DNA-based cell-transformation method could be a simpler, safer way to convert cells into beating heart cells, according to researchers at Johns Hopkins Medical Institutions. It involves no viruses and is a foolproof method to create cardiac cells that beat, they say.
For the first time, scientists have discovered evidence of a human DNA fragment in the genome of bacteria, shedding light on why this particular bug is so adept at surviving in human hosts. The bacteria in question is Neisseria gonorrhoeae, which causes gonorrhea.
Last year an analysis of every gene in your body would have taken more than six months and cost roughly $25 million. The new desktop Genome Sequencer 20 System from 454 Life
Sciences can do it in less than a month for about $300,000. The breakthrough is a fiber-optic chip about the size of a business card that is embedded with 1.6 million wells, each a quarter the size of a human hair. The chip holds hundreds of thousands of DNA fragments.
