This is the first ever scanning electron microscope image of a strand of DNA, and it shows the structure of the minuscule string of molecules that encodes all life.
It’s tiny — that little scale bar in the bottom right corner measures just 20 nanometres — but it definitely shows the characteristic double helix that makes DNA iconic. Those red arrows point out the spacing between the strands as they twirl around the axis. They’re separated by just 2.7 nanometers. Watson and Crick must be proud. [Nanoletters]

No sorry (I’m on Win7). Maybe try the age old turning it off and on again?
And Franklin, lets not forget her! Also, I only found out a couple of years ago that Watson is a bit of a racist not to mention really fond of genetically screening everyone into the perfect human being…
