DNA stories

 
Dark matter makes up about 84% of the universe, which is strange, since we have no idea what it is and we've never seen any of it before. A new type of directional dark matter detector has the potential to spot the signature of dark matter coming from the center of our galaxy, and it's made out of customized strands of DNA and sheets of solid gold.
 
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.
