Physicists Create a Working Transistor From a Single Atom
I am not going to pretend that I fully understand any of this, but the potential for this should be quite amazing, yes?

As for quantum computing... this may help solve the problem of scalability (assuming we don't see issues from the above concern though I'd imagine it would likely be controllable with extensive cooling) but the largest hurdle for a *good* quantum computer remains in the issues of decoherence and the ability for gate logic to be resolved before the decoherence time runs out. Plants can do it, I'm sure we'll figure it out one day too.

OPERA reports two possible errors with their measurement that could take the neutrino results in two different directions.
Now, this might not be the exact best place for my question but given what's going on with OPERA, I have a question. This is a fiber-optics issues as far as I'm aware (from what little detail there is at the moment) but all reports say that *tightening* the cable yields 60 ns of lost time (or the time by which the neutrinos exceed the speed of light) but my gut is looking at that number and saying: "That's 18 meters!" How loose was this cable? Because 18 meters is a helluva distance for something to be considered "loose" and my personal experience with fiber optics usually falls on the picosecond scales where adjustments become a real pain in the rear. Or am I forgetting something in my midnight stupor for which I will be embarrassed come tomorrow since I work with optics (woo! AMO) on a regular basis. (I can understand if the cable were bent or the connector were bent such that the light reflected internally a bunch of times, but just a loose cable is confusing me.)

Twists to quantum technique for secret messaging give unanticipated power
"Quantum cryptography is the ultimate secret message service. Now new research,
to be presented at the 2012 AAAS Annual Meeting, shows it can counter even the ultimate paranoid scenario: when the equipment or even the operator is in the control of a malicious power." See: http://www.spacedaily.com/reports/Tw...power_999.html |

Prosthetics Breakthrough Might Fuse Nerves With Fake Limbs
"The body’s own nerves are arguably the biggest barrier towards turning the
dream of lifelike replacements into a reality. Peripheral nerves, severed by amputation, can no longer transmit or receive any of the myriad sensory signals we rely on every day. Trying to fuse them with robot limbs, to create a direct neural-prosthetic interface, is no easy task. But now a team of scientists believe they’ve overcome that massive barrier. Their research is still in the early stages. But if successful, it’d yield artificial arms and legs that can move with agility; discern hot from lukewarm from freezing; and restore even the subtlest sensations of touch."

Nokia unveils a 41 megapixel phone at MWC.
Well that's a bit misleading. The camera sensor is 41MP, but the best feature of it is the oversampling that produces an incredibly nice 3/5/8 MP picture, with noise effectively eliminated. You can make super high MP pictures as output, but it would look rather crappy. The downside is that it is a Symbian phone. But Nokia is certainly going to port it to Windows in the future. |

There is a HUGE difference between "Japanese, American, or Korean product manufactured in China under the company's supervision and quality testing" and "Chinese product made in China".

I am not a huge fan of them - they blatantly copied stuff from Cisco routers in the early 2000s and there are rumours of them selling those at the time at the local PC Shows. Of course, there is this yesterday : Creative sues Huawei over tech contract The lawsuit is not going to go through I bet.

Canada's northernmost research lab PEARL will be closed due to lack of government funding.
All hail our Conservative Overlords who value political interests over science and research. |
