Yep, you nailed it. That way you can have a wave propagate it's phase faster than light. The tunnel effect experiments I have seen all relate to this phase velocity. And really nothing new. A wave propagating in a gold or silver film will also see the real part of the refractive index being lower than one, and thus go faster than C. However, information can not go faster than light. The article mentioned here, is just a case of successful scientific advertising. It looks good, sounds good but really nothing new.

I am completely tired of this Assange guy. What should I care about big drama show?

It is cheaper, or the cost is lower. You can not have a cheaper cost! Nor can you have cold temperatures for that matter.

We do the concentrating, they do the camping.

to make yourself completely ridiculous.

I work in this line physics, which is really a lot of fun. But: The idea that a practical quantum computer will be around in the foreseeable future is jus plain silly. To worry how such a device would be integrated with the cloud is just absolutely bonkers. What a waste of time this all is.

No, quantum theory does not explain consciousness. That was an easy one. Next!

So, the sample must sit on a very narrow area on the plate with the diffuser. Mah looks like we did not break free from the real limitations then. If we could do this in the middle of a cell, that may be something. The point they make is that you can use this diffuser as a - perfect- lens because one can compensate the phase distortion really well. The image they get is in resolution close to the theoretical wave limit. The surprise is that this works better than the classical approach of making optics: trying to fight off spherical aberration by making good multi-element lenses. So, nice job compensating. But that's it The sample still needs to sit on a small confined are on their plate. There are other techniques that will show the sample with visible light with way more resolution, in particular Scanning Near Field Optical Microscopy will go down to a few nm! So, in my opinion nice work, good prank, but way way over sold. This would have done nice in optics express but seems out of place in Phys Ref letters.

Belgisch? Ja nu ik er aan denk, als we met die stomme Amerikanen hebben afgerekend zijn de Belgen aan de beurt. Of zouden ze in Belgie ook ergens zo'n leuke steen hebben, dat is echt wat voor ze.

OK vaderlanders, het is nu tijd om ten stijde te trekken en dat stelltje eilandbewoners een flink pak slaag te geven! Oranje boven, maar laten we eerst even lekker een pintje pakken. The text above is a call in Dutch to go kick all your American asses, after we had a nice beer that is!

I agree completely. The number 230 is complete and utter Hogwash. What I would like to know as a consumer how well does this car work on gas, and how well on electric charge. Hey the electricity also costs money too, to make it they use fuel, etc! Just more of the bad old GM stuff we all have learned to hate so much (think of the CAFE agreement/program which was complete bull too). Now for the good part, the Volt may be a very nice car, it's a kind of a Prius with a wall plug, I get it. I even may want to have one, but how will I ever find out now the smoke and mirrors have been put up. Bad job GM!

I did not use the Yahoo search engine, actually I don't know why. I tried to use Bing but it is very aggressive in promoting commercial sites, annoying. Did like the video search demo though. Too bad I never search for videos. So what do I care that one engine I don't use gets replaced with an other one I don't use either? Tell me something I do care about...

Now Google came out with their free OS with browser MS is striking back. They will now retaliate with their own free OS and browser system. MS is so competitive, they can not loose, they will dominate the free market, if necessary by bribing their way in. You may have vacuum on your head, but we have more vacuum in our heads.

Maybe we are forgetting that China also has access to the IP addresses allocated to Tibet, Hong Kong and even Taiwan! Now we know why they are occupying these territories, it's all about IPv4!
