Super-Heisenberg scaling
Spanish scientists have produced more precise measurements [with interferometers] than those predicted by Heisenberg's Uncertainty Principle.....big woop?
This does not remove deities(s) with dice, it just shows reduction in certian cases(in this case a "beam of photons to measure the small magnetic field produced by a gas made up of a million ultra-cold rubidium atoms".)

link to paper at nature
...not really related, however, I remember during quantum electro dynamics lectures my professor saying that the Gyromagnetic ratio was the most accurately measured constant and the best confirmation of QED to date, that was 15 years ago...

Mostly webby type tools to scrape data from sites or logs - file2text looks OK (OCR text from images)
screenr session recorder
I'm often looking for ways to record desktop sessions, for example
I mostly use Xvidcap or Istanbul(ogg format can be iffy to convert to mpeg/avi for YT upload (need transcoder - I use ffmeg ) Anywho.... this is a great idea >> SCREENR <<

A few things to try and avoid at a prospective employer....
Here is a wordle of traits I think I should try and avoid at a prospective employer
BAD-STUFF
In a nushell its all Capability Immaturity Model CIM stuff
Rules over results type thinking....
CIM -1 : Obstructive
Processes, however inappropriate and ineffective, are implemented with rigor and tend to obstruct work. Adherence to process is the measure of success in a Level -1 organization. Any actual creation of viable product is incidental. The quality of any product is not assessed, presumably on the assumption that if the proper process was followed, high quality is guaranteed.
Paradoxically, Level -1 organizations believe fervently in following defined procedures, but lacking the will to measure the effectiveness of the procedures they rarely succeed at their basic task of creating...
Agile in its many forms seems to be on the money with this culture and values to get stuff done eg http://agilemanifesto.org/

if you get this you get it...no biggie
\funny a coffee stain for your next (or 1st) scientific paper

The building block of a quantum photon switch
Matthew A. Hall, Joseph B. Altepeter, and Prem Kumar from the Center for Photonic Communication and Computing at Northwestern University in Illinois have constructed a switch which fulfills these requirements and characterize its performance at the single photon level; it exhibits a 200-ps switching window, a 120:1 contrast ratio, 1.5 dB loss, and induces no measurable degradation in the switched photons entangled-state fidelity -less than 0.002
In other words the basic building block for a quantum photon switch

Physical review letter is available to buy here

Solution to Erdös' Distinct Distances Problem has been found
Poincaré conjecture was proved [and confirmed in 2006] and now another of mathematics' holy grails falls by the way side.
While not one of the Millennium problems its very significant none the less...

Information converted to energy
Physicists in Japan have (kind of) built a Maxwell's daemon ( http://en.wikipedia.org/wiki/Maxwell's_demon ) that (kind of) converts information into energy
http://physicsworld.com/cws/article/news/44385
This does not violate the second law of thermodynamics as far more energy is used in the supporting apporatus than is gained in the experiment.
