DNA imaged with electron microscope for the first time
It's the most famous corkscrew in history. Now an electron microscope has captured the famous Watson-Crick double helix in all its glory, by imaging threads of DNA resting on a silicon bed of nails. The technique will let researchers see how proteins, RNA and other biomolecules interact with DNA.

1. First time ? Hardly. Maybe at the best resolution so far.

Google "DNA electron microscope", there are lots of DNA images out there. When I first entered grad school in 1981 this was already being discussed in Molecular Biology classes for undergrads. Why the journo would have thought this is the first such image, I don't know -- perhaps it's the first one without metal coating (normally used to enhance scattering)? Not enough detail in this short article to tell.
