DNA stories

The first human genome cost $3 billion to sequence back in 2003. By 2009, the cost to sequence someone's genome had dropped to more like $50,000. Next year, the target is a mere $1,000, and it'll only take two hours to completely identify all six billion of the base pairs in your DNA to tell you what you're likely to die from first.
Researchers from Ohio State University have figured out how the enzyme responsible for repairing tissues damaged by radiation does its work. Specifically, we're talking about the type of the radiation burns that we all get from time to time: sunburns, and this discovery could mean a lotion that doesn't just make sunburns feel better, but actually cures them.
