Seeing is believing

It was more than 50 years ago that scientists first figured out that DNA was a double helix. Figured out using some indirect measurements like the way X-rays bounced off of DNA and other things like that. Can we see DNA? Sure now with some pretty powerful microscopes. And just recently some scientists in Japan took a look at double stranded DNA and could tell the difference between that and single stranded DNA. The work could have a big impact on things like DNA sequencing.
