Nobel Prize In Chemistry Awarded To Trio For Microscope Advancement
The 2014 Nobel Prize in Chemistry has been awarded to Eric Betzig, Stefan W. Hell, and William E. Moerner for their work in bypassing the limits of traditional optical microscopy. Hell developed a method called Simulated Emission Depletion microscopy, which uses one laser beam to cause a collection of molecules to fluoresce, and another laser beam to cancel out that fluorescence everywhere other than a nanometer-sized volume. Repeating this process over an entire sample provides nanometer resolution for the resulting image. Betzig and Moerner did important work on Single-Molecule microscopy. "The method relies upon the possibility to turn the fluorescence of individual molecules on and off. Scientists image the same area multiple times, letting just a few interspersed molecules glow each time. Superimposing these images yields a dense super-image resolved at the nanolevel." The three scientists' work was pivotal to enabling nano-scale microscopy and allowing detailed study of objects at the molecular level.

Oh, sorry, I misread.
Everything I write is lies, read between the lines.
Nothing simulated about it. ;)
This seems more "Physics", even though the techniques will be used by chemists.

Another Chemistry Nobel award goes to physics researchers. May the besotted and cigarette-smoke wreathed shade of RB Woodward haunt the Committee.
If Slashdot were chemistry it would look like this:Cadaverine
Not surprising that Hell got it.
No idea why Moerner got the Nobel for this, he did a bunch of single molecule work, but not really anything in super res itself. Both X. Zhuang and S. Hess are far more deserving of the prize than that chap.
Also, it's odd: Nobel prizes used to be given to things which hae proven their worth. Super-res microscopy while cool and wile showing a *lot* of promise has not yet reached the stage where it looks more than "very very promising".

Actually STED (stimulated emission depletion) microscopy does NOT "cancel out the fluorescence everywhere other than a nanometer-sized volume," it makes it fluoresce at another color so that you can spectrally distinguish the different areas. To do this you need two lasers, one is a focused to a regular spot (Gaussian beam) and the other has a profile that's more like a donut (see: Laguerre-Gauss beams). When you overlap these two lasers and excite the right molecules, the molecules that are in the ring formed by the donut fluoresce at one color (ie. at the same wavelength as the donut beam) and the ones that are right in the middle fluoresce at another color so with the right spectral filters you can effectively go beyond the diffraction limit with this technique.
Semiconductor manufacturers don't just look at things with sub wavelength resolution, they build things with sub wavelength resolution.
