Fifty-nine years after James Watson and Francis Crick deduced the double-helix structure of DNA, a scientist has captured the first direct photograph of the twisted ladder that props up life.

Enzo Di Fabrizio, a physics professor at Magna Graecia University in Catanzaro, Italy, snapped the picture using an electron microscope.

I'm on the other end of the spectrum... I'm amazed!
But I do dig what could be disappointing with the image, after all the models and artist renditions done.

"But Di Fabrizio and his colleagues developed a plan to bring DNA out of hiding. They built a nanoscopic landscape of extremely water-repellant silicon pillars. When they added a solution that contained strands of DNA into this scene, the water quickly evaporated and left behind cords of bare DNA that stretched like tightropes between the tiny mesas"

Cool enough for me!

It is sort of disappointing, after all of those intricate models built. But still, great to have it captured and see how it looks like.

I was a bit disapointed by the photo but this the first time this has been done and I am looking forward to improvements to image of DNA in the future photos

That is incredibly brilliant.  Here is a close-up of the close-up...it doesn't show anything more really...but it's bigger and bigger is better I think with some things like inconceivably small things like DNA.

Disapointed it wasn't pretty colour or anything fancy? wtf, It's because of comments like that, that the government thinks making ciggerettes plain packaged will stop people from smoking.

TBH It's a Infrared photo done with nanotechnology, be appreciative they even revealed that they had anything at all let alone a picture.

Top work Science world. cheers to ya :D

wait, how is this the first time? I'm amazed that with all the work that has been done sequencing and studying genes in intricate detail that somehow no one ever took a few happy snaps with it.

As electron microscope images of atomic structures go, I'm sure I've seen better... I'm guessing they couldn't really get the DNA into an ideal position. Or maybe all electron microscopes aren't created equal.

I'm in the slightly disappointed camp, seeing as it's mostly just pixel noise... but er... well done chaps. :tu:

Wait a second... I photographed DNA years ago, well that is, if it stands for "Dirty Naked Allison"  ??

Maybe Diseased Nude Aliens? Dog Nosed Adults? Dorky Nerdy Agrophobes? Demonic Nosy Angels? Dusty Nylon Apples? Dark Nutty Acorns? Disorder Nut Affliction?
