Ouya Android Gaming Console Coming in June for $99

Ouya, the Android-based home gaming console, is coming to stores in June. Nearly a year after it originally appeared on Kickstarter, the $99 console will be on sale in big-box retails stores such as Best Buy and Target in addition to GameStop and Amazon.com. Pre-orders have also opened, so eager gamers can reserve their console.

Gamers that jumped on the Kickstarter bandwagon won?t have to wait as long. According to CNET, Ouya CEO Julie Uhrman has announced that Kickstarter backers can expect to receive their consoles sometime in March. Those that can?t wait until June can order from Ouya?s website for an April release.

The console will be outfitted with an Nvidia Tegra 3 quad-core CPU, 1GB of RAM, 8GB of storage and will run on Android 4.1 (Jelly Bean). It will also have HDMI, Ethernet and a single USB 2.o port. Developers have been busy creating titles for the new system and it has a confirmed list of 24 titles including Square Enix?s ?Final Fantasy III? and Cliffhanger Studios? ?Shadowrun Online.?

When Ouya ships, it will include one controller. Additional controllers are going for the ?steep price of $49.99. Why so much? According to Uhrman, the controller will feature a touchpad, which makes it a ?premium? product.?

Using single quantum dots to probe nanowires

Feb. 5, 2013 ? Modern telecommunications happens because of fast electrons and fast photons. Can it get better? Can Moore's law -- the doubling of computing power ever 18 months or so -- be sustained? Can the compactness (nm-scale components) of electronics be combined with the speed of photonics? Well, one such hybrid approach is being explored at the Joint Quantum Institute, where scientists bring together three marvelous physics research fields: microfluidics, quantum dots, and plasmonics to probe and study optical nanostructures with spatial accuracy as fine as 12 nm.

Plasmonics

When light strikes a strip of metal an electron wave can be excited in the surface. Is this "surface plasmon" a bit of light or electricity. Well, it's a bit of both. The wavelength of this electromagnetic wave is shorter and the energy density higher than that of the incoming laser light; the plasmon is thus tightly localized light constrained to propagate along the meal surface. The science of "plasmonics" has arisen to capitalize on various imaging, sensing, and processing abilities inherent in plasmons. To start with, though, one needs to know exactly what happens at that laser-excited metallic surface. That light is converted into the plasmonic wave; later the energy can be reconverted into light.

Here's where the JQI experiment comes in. The main result of the work, published February 5 in the journal Nature Communications, is to provide a map showing how the metal strip, in this case a silver wire 4 microns long and 100 nm wide, lights up.

Microfluidics and Quantum Dots

The other two chief components of the experiment, in addition to plasmonics, are microfluidics and quantum dots. Microfluidics, a relatively new science all by itself, features the movement of nanoliter volumes of fluids through channels defined on microchips, analogous to the conducting paths strung across microprocessors for carrying electrical currents. Quantum dots, nanometer-sized semiconductor balls, are tailored to possess a specified set of allowed energy states; in effect the dots are artificial atoms that can be moved around. In the JQI experiment the 10-nm-wide dots (the important cadmium-selenide layer is only 3 nm thick) float in a fluid whose flow can be controlled by varying an applied voltage. The dots are drawn up close to the nanowire as if they were mines next to a submarine.

Indeed the dot is there precisely to excite the wire. The dot is fluorescence machine -- in a loose sense a nanoscopic lightbulb. Striking it with green laser light, it quickly re-emits red light (one photon at a time), and it is this radiation which excites waves in the nearby wire, which acts like an antenna. But the interaction is a two-way street; the dot's emissions will vary depending on where along the length of the wire it is; the end of the wire (like any pointy lightning rod on a barn) is where electrical fields are highest and this attracts the most emission from the dot.

A CCD camera captures light coming from the dots and from the wire. The camera qualities, the optical properties of the dot, the careful positioning of the dot, and the shape and purity of the nanowire combine to provide an image of the electric field intensity of the nanowire with 12-nm accuracy. The intensity map shows that the input red light from the quantum dot (wavelength of 620 nm) has effectively been transformed into a plasmonic wavelength of 320 nm.

Chad Ropp is a graduate student working on the project and the lead author on the paper. "Plasmonic maps have been resolved before, but the quantum mechanical interactions with a single emitter have not, and not with this degree of accuracy," said Ropp.

Possible Applications

In an actual device, the quantum dot could be replaced by a bio-particle which could be identified through the nanowire's observed effect on particle's emissions. Or the dot-wire duo could be combined in various configurations as plasmonic equivalents of electronic circuit components. Other uses for this kind of nanowire setup might exploit the high energy density in the plasmonic state to support nonlinear effects. This could enable the nanowire-dot combination to operate as an optical transistor.

Battle-scarred skull of suspected King Richard III revealed

A battle-scarred skull discovered beneath a parking lot in England could be that of King Richard III, who died in battle in 1485.

The University of Leicester released the skull image ? the first photo of the human remains that may belong to the English monarch ? ahead of a big announcement on the identity of the bones, scheduled for Monday (Feb. 4) morning.

"The skull was in good condition, although fragile, and was able to give us detailed information about this individual," Jo Appleby, an archaeologist at the University of Leicester, said in a statement.

Archaeologists had unearthed the skeleton, including its skull, last year in the choir of what was the medieval church Grefriars, which had been buried under a parking lot. Historical records suggested King Richard III was buried there after he died at the Battle of Bosworth Field, during the War of the Roses, an English civil war.

To get as close a look as possible at the skull, and find out whether it once held the English crown, researchers used computed tomography (CT) scanning.

"In order to determine whether this individual is Richard III we have built up a biological profile of its characteristics. We have also carefully examined the skeleton for traces of a violent death," Appleby said. [See Images of the Skull & Search for Richard III's Grave]

Skeletal signs

Appleby and colleagues had good reasons to think the remains came from the famous king, best known through William Shakespeare's fictional account of him in "Richard III." For instance, not only was the skeleton male, it was found in the church choir area where historical records would suggest Richard III was buried. The skull also showed signs of being wounded, as if it were cut clean off his body with an axe or sword, something consistent with a battle death.

Scientists also found a barbed arrowhead in the skeleton's spine, which showed signs of scoliosis. Such an abnormally curved spine would've made its owner's right shoulder sit higher than the left, matching contemporary portrayals of Richard III. However, unlike some later accounts, the king was not a hunchback.

The CT scans will allow scientists to create a 3-D image of the body, over which they can place flesh; same goes for the skull, which the team plans to reconstruct to show what the man's face would've looked like, though this procedure can be somewhat unreliable. The team also said they would analyze any DNA recovered from the bones. Such results could then be compared to those of a direct descendant of Richard's sister, who was uncovered by John Ashdown-Hill, author of "The Last Days of Richard III." From those remains, scientists have mitochondrial DNA, or the DNA inside the cell's energy-making structures, which gets passed down only by mothers.

Strange tales

Richard III ruled from 1483 to 1485, becoming the last English king to die in battle. Though it was known the king was buried at the Franciscan Friary (known as Greyfriars) in Leicester, the grave and church itself were eventually lost. Even so, interest in the king led to some far-fetched grave tales about the grave's whereabouts, including one purporting the bones were thrown into the Soar River. "Other fables, equally discredited, claimed that his coffin was used as a horse-trough," Philippa Langley, a Richard III Society member, said in a statement.

The researchers started digging beneath the Leicester City Council parking lot on Aug. 25. Since then, they have found the church and a 17th-century garden marked by paving stones. Records suggest mayor of Leicester Robert Herrick built a mansion and garden on the medieval church site years after the king's death, reportedly placing in the garden a stone pillar inscribed with, "Here lies the body of Richard III sometime King of England." [10 Weirdest Ways We Deal With the Dead]

If the bones turn out to belong to King Richard III, where will they be re-interred? The University of Leicester has jurisdiction over the remains, and had said last year the remains would be buried under Leicester Cathedral.

However, other interested parties have their own opinions: The Richard III Foundation and the Society of Friends of Richard III, based in York, England, argue the remains should be reburied in York, since the king was fond of that city. The Richard III Society has remained officially neutral. Meanwhile, some online petitions have argued the reburial should take place at Westminster Abbey or Windsor Castle.

"If the identity of the remains is confirmed, Leicester Cathedral will continue to work with the Royal Household, and with the Richard III Society, to ensure that his remains are treated with dignity and respect and are reburied with the appropriate rites and ceremonies of the church," the Very Reverend Vivienne Faull, the Dean of Leicester, said in a statement.

2012 Directors Guild Award Winner Announced

Janson Jinnistan

You know directors direct actors, not write stories. Affleck had no responsibility for writing the "story" of "Argo", but he was responsible for directing performances and choosing the best takes. The best directors this year were not nominated here - the Andersons, Dominik, Carax and Tarantino. Out of the nominees, I'd say it was probably Lee who deserves it most.
