Nobel Prize In Chemistry Shared By 3 For Cryo-Electron Microscopy (www.cbc.ca)
Dave Knott writes: The Nobel Prize in Chemistry was awarded on Wednesday to researchers who developed cryo-electron microscopy, which is described as a way to create detailed images of the molecules that drive life -- a technology that allows scientists to visualize molecular processes they had never previously seen. This is decisive for both the basic understanding of life's chemistry and for the development of pharmaceuticals. From the Nobel committee's press release: "Electron microscopes were long believed to only be suitable for imaging dead matter, because the powerful electron beam destroys biological material. But in 1990, Richard Henderson succeeded in using an electron microscope to generate a three-dimensional image of a protein at atomic resolution. This breakthrough proved the technology's potential. Joachim Frank made the technology generally applicable. Between 1975 and 1986 he developed an image processing method in which the electron microscope's fuzzy two-dimensional images are analyzed and merged to reveal a sharp three-dimensional structure. Jacques Dubochet added water to electron microscopy. Liquid water evaporates in the electron microscope's vacuum, which makes the biomolecules collapse. In the early 1980s, Dubochet succeeded in vitrifying water -- he cooled water so rapidly that it solidified in its liquid form around a biological sample, allowing the biomolecules to retain their natural shape even in a vacuum. Following these discoveries, the electron microscope's every nut and bolt have been optimized. The desired atomic resolution was reached in 2013, and researchers can now routinely produce three-dimensional structures of biomolecules."
Who is going to win the Peace Prize this year? I'm voting for BeauHD.

Seriously , that motherfucker BeauHD, Beau Hamilton, is the worst editor fuckin ever.
Slashdot is like a shit repost of reddit and hackernews.
Its not so bad as going the way of kuro5hin or digg, but its fuckin bad.
We have the technology to see Twitler's hands. Or his penis.
Also his brain.
Did you know Twitler's speech on the Las Vegas massacre was a lip sync job? I mean honestly, does anyone think he could have stayed on topic for so long, and without once talking about how great he was.
Microscopy is a smal sea, like your DAMN balls
I think I have seen images like this before. I always assumed they were just mathematically constructed models, not actual images of these molecules (even if there is some images processing). Pretty cool stuff.
If the biomolecules are not metallic then the electron microscopy is not properly adequate for it.
Somehow I missed knowing that we could do this. It is amazingly cool, and is absolutely a Nobel level advance.

Freezing water, even instantly, changes the chemistry. This work is no doubt fundamental, but far from complete.
I applaud this work, and based on what we *knew* before is it is certainly worthy of worldwide recognition, however we still have a long way to go before we truly understand, let alone control it.
If anyone does ever truly understand it, only God(TM, patent pending) could save the rest of us.

It's not quite clear why there are different people for both pizes, though.

Presumably this means cells don't get damaged when frozen using his method? One less barrier so people could be frozen and re-animated! ;-)
"Dubochet succeeded in vitrifying water -- he cooled water so rapidly that it solidified in its liquid form around a biological sample, allowing the biomolecules to retain their natural shape even in a vacuum"
Method isn't used on cells. It's used on purified biomolecules like proteins and nuclei acids.
Every year I always look forward to this prize. Great work, scientists! https://williamreview.com/vids...

I am guessing this will help to analyse gases which have been super cooled to a liquid state, superfluids?
