What DNA actually looks like

Researchers at the Istituto Italiano di Tecnologia strung a molecule between two nano-towers and subjected it to transmission electron microscopy at extreme magnification. Until last week the double helix model had been an indirect inference, albeit an extremely robust one, from techniques like crystallography. The new paper, in Nano Letters, is just the thing for those who like to see evidence with their own eyes.
