Leader of Toots and the Maytals injured at concert
RICHMOND, Va. (AP) ? Officials say the leader of the reggae band Toots and the Maytals was injured when a 19-year-old man threw a bottle and hit the singer during a concert in Richmond.
Police said Sunday the man has been charged with aggravated assault. Authorities have not identified him.
The Richmond Times-Dispatch reports that (http://bit.ly/17PhlkD ) Frederick "Toots" Hibbert was treated at a hospital for a cut to his head and released.
Hibbert was hit by a glass bottle thrown from the crowd Saturday night as the band was performing at the Dominion Riverrock outdoor sports and music festival. The band stopped playing after he was hit.
Festival organizers say Hibbert was in good spirits despite the traumatic event and regretted that the concert had to be stopped early.

Volcano ash 15,000 feet high: Could Pavlof eruption affect air travel?
For the second time in a month, a volcano in Alaska's remote Aleutian chain has erupted, spotlighting America's most active portion of the Ring of Fire.
In early May, Cleveland Volcano saw three quick explosions ? part of a pattern of increased activity since 2011. Reports suggest that it is still rumbling, with lava flows recorded as recently as Tuesday. But no ash clouds have been seen for a week.
Now, Pavlof Volcano is erupting, and local reports suggest that it might be just getting started.
RECOMMENDED: Are you scientifically literate? Take our quiz
The event began on Monday, with ash clouds reaching 15,000 feet. By Wednesday, the ash had hit 20,000 feet, and the National Weather Service had designated the eruption a "significant meteorological event" that could disrupt local air traffic.
The ash from Pavlof would have to reach 35,000 feet to disrupt international flights that use Alaskan airspace as a corridor for traffic between Asia and North America. For now, that is not forecast, but the eruption bears watching, experts say.
Pavlof has "reared its ugly head a couple times in the last 14 years, but nothing this significant," Theo Chesley, a pilot for a local air taxi who flew by the volcano twice Thursday, told Alaska Dispatch Saturday.

The eruption could go on for months, said Jeff Freymueller, coordinating scientist at the Alaska Volcano Observatory, in the Alaska Dispatch report. "At this point we're assuming that it's going to be at least weeks."
Ninety percent of air freight from Asia to Europe and North America flies over Alaska airspace, scientist Steve McNutt told CNN.
"We think of the Aleutian Islands as being remote and desolate, but when you come up to 30,000 feet we are talking about 20 to 30,000 people there every single day," said John Power, a scientist from the US Geological Survey, in the CNN report.
Pavlof is an 8,261-foot cone near the tip of the Alaska Peninsula ? a long, thin finger of land that extends southwest from the Alaska mainland. From there, the Aleutian Islands sweep out into the Pacific toward Russia in a 1,200-mile chain of volcanic islands. Cleveland Volcano, which reaches an elevation of 5,676 feet, is on uninhabited Chuginadak Island.
Cleveland and Pavlof "are very similar, and both have the ability to erupt," said Dr. Power.
The Aleutians and the southern coast of Alaska make up the northern edge of the Ring of Fire ? an area of heightened volcanic and seismic activity that circles the Pacific from New Zealand to the Philippines to Mexico to Chile.
Though the Ring of Fire also includes parts of Washington, Oregon, and California, Alaska is by far the most volcanically active area in the United States. The state's 40 active volcanoes account for more than 80 percent of the active volcanoes in the country.
Pavlof last erupted in 2007 and is "one of the most historically active volcanoes in the Northern Hemisphere," Power told CNN.
About 40 miles southwest in Cold Bay, Alaska (population 108), residents are worried about the potential ash fall, which could damage power generators. Currently, winds are blowing the ash away from the village.
??Everybody is thinking about it,?? local air traffic controller John Maxwell told the Associated Press. ??Not that anybody is afraid they?re going to be like Mount Vesuvius and turned into little mummies.??

INDIANAPOLIS (AP) ? Point guard George Hill will be a game-time decision as the Pacers try to close out the Knicks.
After Indiana's shootaround Saturday morning, coach Frank Vogel did not say whether Hill had passed his concussion tests. Hill must do so before returning to action. Vogel says he is preparing to be without Hill for Game 6 on Saturday night.
Hill missed Game 5 after complaining of headaches. Trainers later diagnosed him with a concussion, holding him out of a game the Pacers lost 85-75. They still lead the best-of-seven Eastern Conference semifinals 3-2 and play at home Saturday. The Pacers are 5-0 in home playoff games this season, winning each by at least 11 points.
The Pacers started D.J. Augustin in Hill's spot Thursday night.

Spacewalkers hopeful new pump control fixes space station coolant leak
Flakes of ammonia were discovered leaking out of the cooling system on International Space Station, and two astronauts are taking a spacewalk to repair it. NBC's Tom Costello reports.
By Tariq Malik, Space.com
Two spacewalking astronauts may have fixed an ammonia leak outside the International Space Station Saturday, perhaps bringing the outpost's vital cooling system back up to full strength.
Clad in bulky spacesuits, NASA astronauts Chris Cassidy and Tom Marshburn replaced a pump control box thought to be responsible for the?leak of ammonia, which cools down the orbiting lab's systems. It looks like this fix did the trick, as no ammonia flakes were seen streaming into space when Mission Control turned on the newly installed gear.
"We're not seeing anything," Cassidy said at around 12:35 p.m. EDT (1635 GMT), several minutes after the pump was turned on. "No snow." [Emergency Spacewalk to Fix Space Station Leak in Photos]
NASA TV
NASA astronaut Chris Cassidy (striped spacesuit) holds an ammonia pump control box during a spacewalk to hunt for an ammonia leak outside the International Space Station on May 13, 2013. The spacesuit of astronaut Tom Marshburn can be seen behind him.
NASA officials stopped short of declaring total victory, however, saying that time will tell if the fix holds.
"It will take some diagnostics, still, over the course of the next several days by the thermal systems specialists to fully determine that we have solved the problem of the?ammonia leak,"?NASA spokesperson Rob Navias?said during live mission commentary. "But so far, so good."?
An emergency spacewalk?
Cassidy and Marshburn floated outside the space station at 8:44 a.m. EDT (1244 GMT) today, beginning what officials described as a six-hour detective's investigation to find ? and hopefully fix ? the ammonia leak.
Cassidy, who led the spacewalk, reported seeing "no smoking gun" as he and Marshburn began their inspection of the old ammonia pump control box, one of several on the space station's far left segment, known as the Port 6 truss. It is part of the cooling system for the two wing-like solar arrays extending from the Port 6 segment.
Upon removing the box, the spacewalkers still saw no signs of ammonia flakes.
"It looks really, really clean, surprisingly so," Cassidy said while peering deep inside the box using what looked like a dentist's mirror.
NASA
Location on International Space Station where spacewalkers worked to replace the pump control box.
The ammonia leak was first spotted by space station astronauts last Thursday, when the crew reported seeing flakes of frozen coolant floating outside. They recorded video of the ammonia leak and sent it down to Mission Control for analysis.
While the leak posed no danger to the space station's crew, it could have impacted the amount of power available for daily operations on the orbiting laboratory if left unchecked, NASA officials said. So Cassidy and Marshburn were sent out on an emergency spacewalk to attempt a fix.
The roughly 48-hour turnaround made this the?fastest spacewalk plan of its kind?ever devised for a space station crew, mission managers have said.
By about 1:00 p.m. EDT (1700 GMT), a little more than four hours into the spacewalk, Cassidy and Marshburn were getting ready to head back to a space station airlock, where they must clean their spacesuits to make sure they don't bring any toxic ammonia into the orbiting lab.
A history of ammonia leaks
This is not the first time astronauts have had to tackle ammonia leaks in the?space station's cooling system?during a spacewalk.
Last year, astronauts Sunita Williams of NASA and Akihiko Hoshide of Japan performed a spacewalk to fix a leak that was also found on the Port 6 truss. That ammonia leak was in the same coolant loop as the current leak, but engineers do not yet know if the two leaks are related.
The station's Port 6 truss is the oldest piece of the space station's scaffolding-like backbone and carries two of the outpost's eight wing-like solar arrays. It launched in November 2000 and was originally installed on the station's roof, towering over the orbiting lap. In 2007, visiting shuttle astronauts relocated the P6 truss to its final location on the station's far left side.
NASA
Expedition 35 crew members Chris Cassidy and Tom Marshburn participated in a "precedent-setting" spacewalk on May 11, the fourth extra-vehicular outing for both men.
This was the fourth spacewalk for both Marshburn and Cassidy, and the 168th total to support space station assembly and maintenance. Inside the?International Space Station, commander Chris Hadfield of Canada and Russian cosmonauts Roman Romanenko, Alexander Misurkin and Pavel Vinogradov followed the spacewalkers' progress.
Today's spacewalk comes just two days before Hadfield, Marshburn and Romanenko are due to return to Earth to end their five-month mission in space.
The three men are due to leave the space station on Monday and land on the steppes of Kazakhstan in Central Asia. Those plans are still going forward, space station mission managers said.

Police: 17 wounded in Mother's Day parade shooting
NEW ORLEANS (AP) ? Gunmen opened fire on dozens of people marching in a Mother's Day second-line parade in New Orleans on Sunday, wounding at least 17 people, police said.
Police spokeswoman Remi Braden said in an email that many of the 17 victims were grazed and most of the wounds weren't life-threatening. No deaths were reported.
Police Superintendent Ronal Serpas told reporters that a 10-year-old girl was grazed in the shooting around 2 p.m. She was in good condition. He said three or four people were in surgery, but he didn't have their conditions.
Officers were interspersed with the marchers, which is routine for such events. As many as 400 people joined in the procession that stretched for about 3 blocks, though only half that many were in the immediate vicinity of the shooting, Serpas said.
Police saw three suspects running from the scene in the city's 7th Ward neighborhood. No arrests had been made as of late afternoon.
Second-line parades are loose processions in which people dance down the street, often following behind a brass band. They can be impromptu or planned and are sometimes described as moving block parties.
A social club called The Original Big 7 organized Sunday's event. The group was founded in 1996 at the Saint Bernard housing projects, according to its MySpace page.
The neighborhood where the shooting happened was a mix of low-income and middle-class row houses, some boarded up. As of last year, the neighborhood's population was about 60 percent of its pre-Hurricane Katrina level.
Police vowed to make swift arrests.
"We'll get them. We have good resources in this neighborhood," Serpas said.

How to Pull Off a $45 Million Global ATM Heist
Want to pull off your own $45 million worldwide ATM heist? It might not be that easy, experts say.
The spectacular global scheme uncovered yesterday (May 9) by federal prosecutors was cinematically epic, involving hacked prepaid debit cards, dozens of "cashers" simultaneously hitting ATMs in two dozen countries, a staggering cash payoff and an equally movie-ready mob hit.
But for anyone seeking to replicate the feat, it could take months of planning, deep insider knowledge of financial databases and top-notch technical abilities.
"On a scale of one to 10, this is a nine," said Ori Eisen, founder and CEO of San Jose, Calif.-based security firm Fourth Parameter. "This specific attack requires a very high level of sophistication and perhaps some inside help. It requires organization and planning, and you can't execute it every day."
Tip of the iceberg
The indictments unveiled by Loretta E. Lynch, U.S. Attorney for the Eastern District of New York, involved only the local New York cashing crew, the low end of the totem pole.
Still unnamed are the masterminds of the entire operation and their locations, and the hackers they paid to break into the computer systems of card-payment processors in the United States and India.
The hackers, or possibly bank employees who were paid off, raised the account balances on between 10 and 20 prepaid debit cards so that the cards, and any copies of them, could be used to make unlimited ATM cash withdrawals.
"The attack is really quite specific in what it targeted," said Roel Schouwenberg, a senior anti-virus researcher with digital-security firm Kaspersky Lab. "I wouldn't be surprised if there was an insider component to this story. The global nature also meant the withdrawal part of the operation had to be very coordinated."
The eight men named in the indictments, all residents of Yonkers, N.Y., just north of New York City, made maximum withdrawals using "cloned" debit cards from hundreds of Manhattan ATMs in two separate sprees in December 2012 and February 2013 that lasted only a few hours each.
Their withdrawals were timed with other sprees using the same card numbers in several other countries.
"It took a well-coordinated and very busy industrious criminal gang ? a directed mob," said George Smith, senior fellow with Washington, D.C.-based think tank GlobalSecurity.org.
"If you have such a similar mob you can put together, you can think about trying to duplicate this type of thing," Smith said. "But you'll have to have some startup capital, since it's not quite something you can just walk out the door and assemble off the cuff."
[5 Steps to Better Credit-Card Security]
Regional representatives
In the February cashing binge, two of the New York men made their way down Broadway for several hours, hitting every ATM from the Upper West Side to Union Square, netting approximately $2 million in cash. They then took photos of themselves posing next to a stack of bills.
"The picture of two of the New York errand boys flaunting their stack of bundled cash in the car won't strike anyone as being from the high end of innovation and thinking," Smith pointed out.?
Hiring local petty criminals to do the dirty work also increases the risk of exposure, said Sean Sullivan, a security adviser with the F-Secure security firm in Helsinki, Finland.
"The need to have lots of money mules to withdraw all the cash seems to be the big complication in getting away with the crime. That leaves a trail for law enforcement," Sullivan said. "I'm sure there are similar hacks by smarter players that don't overdo it ? and so don't make it a federal case."
"The good news is that it's not individuals who are having money stolen from their accounts, but rather the financial institutions," said Graham Cluley, a senior technology consultant with the Sophos security firm in Abingdon, England. "Mind you, ultimately, they pass the costs of such things on to the general public."
Can anyone do this?
One might imagine there are thousands of small-time crooks around the world reading about the heist and wondering, "How can I pull this off?"
"You can't, unless you have an insider at the financial institution who will help cover it up, and raise the credit lines without tripping any fraud detection," Eisen said.
"The scale and nature of this operation can't be executed by low to mid-level gangs," he said. "This is the high end of organized cybercrime ? the loot is usually commensurate with the sophistication of the criminal."
The alleged leader of the New York crew, Alberto Yusi Lajud-Pe?a, wasn't around to be indicted with the other accused cashers. He was murdered in late April in the Dominican Republic, where he had fled after arrests of his alleged accomplices began in late March.
According to Dominican press reports cited by Wired magazine, two masked men burst into a room where Lajud-Pe?a was playing dominoes, shot his companions in the legs and then killed him. The gunmen didn't touch a manila envelope containing $100,000 in cash.
"There are likely to be gangs of other people outside the United States who were involved in this, and it will be interesting to see if there are further arrests overseas," Cluley said.
[Top Mobile Banking Security Tips]
Financial safeguards aren't perfect
Despite the layers of security around modern financial computer systems, enterprising criminals can often find a way in, Smith said.
"The worldwide network of global money card transactions is so omnipresent and complicated there are always openings, banks and repositories which cannot secure things," he said.
Robert Graham, CEO of Errata Security in Atlanta, noted that the banks that had issued the prepaid cards were in the United Arab Emirates and neighboring Oman.
"Banks in Third World countries have horrible cybersecurity, so it's pretty easy to break in and steal information," Graham said. "All it takes is the very simplest hacks, like SQL injection or phishing."
"We don't know how they managed to break into the card processors' network to remove the spending limits on the prepaid cards," Cluley said. "For obvious reasons, the organizations concerned aren't offering details ? but hopefully, they are investigating and tightening their systems for their own sakes."
The one part you can pull off
There was, however, one simple aspect of the operation. Cloning credit or debit cards, especially the old-fashioned magnetic-stripe version still used in the U.S., is commonplace.
"A magnetic-stripe writer costs $200," Graham said. "With such a device, you can easily program any credit card in your wallet to one of the stolen accounts."
In fact, almost any magnetic-stripe card can become a "clone" of a credit card or debit card ? a library card, a hotel-room key, a store membership card. Blanks can also be obtained easily.
The card cloning in such schemes is usually left to the local cashing crews, who have been electronically provided with the card account details and ATM PIN numbers, security researcher Paul Ducklin explained on Sophos' Naked Security blog.
In Europe, magnetic-stripe cards have been replaced with EMV, or chip-and-PIN, cards that contain a computer chip and electronically interact with the card reader. It's still possible to clone those, but it takes more sophistication and pricier equipment.
"Having EMV chip cards could really help here, and that's something where the U.S. is very seriously lagging behind," Schouwenberg said. "They've been the standard in Canada and Europe for some years now, but [are] virtually non-existent over here."
Penalties and punishments
Authorities in several countries are trying to work their way up the chain of command to nail the masterminds of this scheme, but if history is any indication, the top conspirators may get off scot-free.
Sullivan and Ducklin pointed out that in a similar scheme in 2009, cybercriminals netted $9 million through hacked payroll debit cards, yet the head of a Chicago-based cashing crew that acted as part of the scheme was sentenced to only 30 months in prison.
The St. Petersburg-based mastermind of the 2009 scheme was given no prison time ? only probation ? by Russian authorities in exchange for his cooperation.
In the case announced yesterday, the seven surviving members of the New York crew face maximum sentences of 10 years for each count of money laundering and 7.5 years for each count of conspiracy. It's not clear how many counts each individual has been slapped with.
Compare those penalties with the 35-month federal sentence handed down in March to hacker Andrew "Weev" Auernheimer for accessing account information posted on a public website, or with the 50 years in prison digital-rights activist Aaron Swartz faced for downloading archived academic journals.
Or, as a commenter on Slashdot wryly observed, "This is not how bank fraud should be done. The right and proper way is to become too big to fail, too big to jail, rig the LIBOR rates, create systematic rigging, award oneself huge salaries and bonuses, threaten worldwide economic collapse, hold governments to ransom and get huge bailout money."

Toshiba Excite 10 SE
A year ago, Android tablet manufacturers built and priced their high-end options to compete with the Apple iPad. That ill-fated endeavor has largely come to an end. A more common trend these days is repackaging and repurposing what were once high-end models and offering them at more palatable prices. The Toshiba Excite 10 SE is a perfect example, with nearly identical specs as last year's $600 Toshiba Excite 10, but now at a more reasonable price ($349.99/16GB, $399.99/32GB list). Some sacrifices had to be made, like ditching the aluminum build for plastic, but the quad-core Tegra 3 chip remains, and it's now running Android 4.1 "Jelly Bean." That said, the Excite 10 SE is a fine Android tablet, but there are still better options, like the versatile Asus Transformer Pad TF300 or the easy-to-use Amazon Kindle Fire HD 8.9", for those who don't need a traditional Android experience.
Design and Features
The Excite 10 SE is nearly identical to the original Excite 10, except for one key feature: The SE swaps out the aluminum back for a plastic one. Even the texture is the same, and the plastic is rigid enough to keep the Excite 10 SE from feeling flimsy. At 10.3 by 7.1 by 0.4 inches (HWD) and 1.41 pounds, the 10 SE is also a bit thicker and heavier than the original (10.3 by 7.0 by 0.35 inches and 1.32 pounds). Another key difference is port selection: The Excite 10 included micro USB and micro HDMI ports, as well as a full-sized SD card slot, while the 10 SE has only a micro USB port and a microSD card slot. It's still nice to have storage expansion options, but the omission of micro HDMI out, for connecting the tablet to an HDTV, is a bummer. On the bright side, the 10 SE sheds the proprietary power connector, using the micro USB port for charging and data transfer. ?
You still get two stereo speakers along the bottom edge, which get loud for tablet speakers, but still sound harsh and lack bass punch. There's a front-facing 1.2-megapixel camera centered above the screen and a rear-facing 3-megapixel camera on the top left corner of the back.
The 10.1-inch display is the same 1,280-by-800-pixel IPS panel found on the original Excite 10. That's a good thing, as the screen looks sharp, colors are vibrant, and viewing angles are wide. It's also not as sharp as the Nexus 10's?1080p display, and it's not the brightest display; the Asus TF300 trumps the Excite 10 SE here.? Like some other features of the Excite 10 SE, the display is good, but it doesn't truly excel against the competition.
The Excite 10 SE is a Wi-Fi-only tablet that connects to 802.11b/g/n networks on the 2.4GHz frequency. Not only is access to the faster 5GHz frequency omitted, but during testing I noticed that the Excite 10 SE sometimes took a long time to reconnect to Wi-Fi networks when woken from sleep. You also get GPS, along with Bluetooth 3.0, which let me pair the tablet with wireless headphones easily.
Toshiba offers 16GB and 32GB models for $349.99 and $399.99 respectively. For expansion, the open microSD card slot accepted our 32 and 64GB SanDisk cards without a problem.
Performance and Android
The Excite 10 SE is equipped with the same quad-core 1.3GHz Nvidia Tegra 3 processor found in the original Excite 10. That was the fastest chip available last year, but SoC's have progressed since then, with tablets like the Nexus 10 powered by the faster Samsung Exynos 5250 1.7GHz dual-core ARM Cortex-A15 processor. The Excite 10 SE slightly edged out the Asus Transformer Pad TF300, which is also powered by a quad-core Tegra 3 chip, in our benchmarks, but in day-to-day use, these two tablets offer comparable performance. Web browsing is smooth, apps open quickly, and even graphically intensive games like Shadowgun THD run without a hitch on the Excite 10 SE.
Toshiba used a very lightly skinned version of Android 4.1.1 "Jelly Bean" in the Excite 10 SE. In fact, the only modifications you'll find are SRS audio enhancements and a Balanced Power mode. Playing with the SRS settings yielded subtle changes in audio output. I found the Volume Boost setting to be the most useful. It does what it says, but also makes things sound a bit harsher. Balanced Power mode isn't the same as Asus's varying power modes on its Transformer line of tablets. Instead of reigning in the processor, the only noticeable difference I could see in Balanced Power mode was slightly dimmed display brightness.
While Toshiba made only minor modifications to Android, it loaded up the Excite 10 SE with a good deal of bloatware. Aside from some useful Toshiba branded apps, like the file manager and media player apps, there are useless and undeletable apps like eBay, a redundant Toshiba app store, and a slew of Wild Tangent linked games. The Google Play app store is here, granting access to more than 800,000 apps and a growing selection of media content.
Media support is good. In my tests, the Excite 10 SE played H.264, MPEG4, WMV, DivX, and Xvid videos smoothly at up to 1080p resolution without a hitch. For audio, the tablet can handle WMA, OGG, WAV, MP3, FLAC, and AAC formats.
The 3-megapixel rear-facing camera is a downgrade from the 5-megapixel camera on the original Excite 10. The Excite 10 captured average, if somewhat noisy images, and the Excite 10 SE fairs even worse. Indoors and under low lighting, images are a grainy mess with dull colors and noise wiping away fine detail. Outdoors and under good lighting images improve, but not by much. Video tops out at 640 by 480 pixels, with slow, jerky frame rates. Performance is underwhelming, but that's the case with most tablet cameras.
In our battery rundown test, which loops a video with screen brightness set to maximum and Wi-Fi on, the Excite 10 SE lasted 7 hours, 37 minutes. The 10-inch Transformer T300 turned in a slightly better 7 hours, 53 minutes, while the same-size Iconia Tab A510 turned in 9 hours, 34 minutes on the same test.
Conclusions
The Toshiba Excite 10 SE is a fine Android tablet, it just lacks the stand-out features or low price that set most top-notch competitors apart. The Asus Transformer Pad TF300 offers the same performance for the same price, but also has the ability to add on an excellent keyboard dock, turning it into a productivity powerhouse. Android enthusiasts will likely be happier spending $50 more for the Nexus 10, while those who don't care either way should check out the Amazon Kindle Fire HD 8.9". The Barnes & Noble Nook HD+ could even make a nice alternative with a lower price tag, sharp display, and recent addition of Google Play.?

Russia points to discord over proposed Syria peace process
MADRID (Reuters) - Spanish MotoGP rider Hector Barbera and his girlfriend were charged on Friday following a domestic dispute, court sources said after a hearing in Jerez. The 26-year-old FTR Moto rider was ordered to do community service while the girlfriend, who was not identified by name, had her sentence suspended because she had no previous convictions, according to the sources. "I would like to make clear that it was nothing more than a domestic argument which has already been resolved by the court in Jerez and which both parties have accepted," Barbera said in a later statement. ...

Ouya raises $15 million, delays game console launch until June ...
The makers of the Ouya $99 video game console have raised $15 million from investors, which the company promises to use to increase production of the little game console.
On the other hand, customers who have pre-ordered will still have to wait a little longer than planned. Originally the first Ouya devices sold through retail channels were expected to ship June 4th. Now that date has been pushed back to June 25th.
Ouya says pushing back the launch date by 3 weeks will help the company meet the larger-than-anticipated demand. But according to Joystiq, the Ouya team is also using the extra time to revamp the design of the game console?s wireless gamepad a bit.
Many folks who donated to Ouya?s fundraising campaign on Kickstarter have been using pre-release hardware for the last few weeks, and one of the top complaints has been that some of the buttons on the controller can get stuck.
The Ouya game console features an NVIDIA Tegra 3 quad-core processor and Android-based software. While it?s based on Android, it has a custom user interface and game store.
The goal of the project wasn?t just to release an inexpensive game console, but also to lower the barriers for game developers looking to write software that you can play on a television screen. So while the Ouya console might not have the same kind of power (or the same level of games) as the latest PlayStation or Xbox consoles, it does offer a new kind of living room gaming experience.
Early reviews of the pre-release hardware have been supportive of the device?s potential, but critical of the current state of the platform. But many of the issues people have had seem like they could be addressed by software and hardware updates.
Ouya is continuing to ship devices to backers of its Kickstarter campaign. You can pre-order a retail unit for delivery in late June from Amazon

Injectable nano-network controls blood sugar in diabetics for days at a time

In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests. The work was done by researchers at North Carolina State University, the University of North Carolina at Chapel Hill, the Massachusetts Institute of Technology and Children's Hospital Boston.
"We've created a 'smart' system that is injected into the body and responds to changes in blood sugar by releasing insulin, effectively controlling blood-sugar levels," says Dr. Zhen Gu, lead author of a paper describing the work and an assistant professor in the joint biomedical engineering program at NC State and UNC Chapel Hill. "We've tested the technology in mice, and one injection was able to maintain blood sugar levels in the normal range for up to 10 days."
When a patient has type 1 diabetes, his or her body does not produce sufficient insulin, a hormone that transports glucose ? or blood sugar ? from the bloodstream into the body's cells. This can cause a host of health effects. Currently, diabetes patients must take frequent blood samples to monitor their blood-sugar levels and inject insulin as needed to ensure their blood sugar levels are in the "normal" range. However, these injections can be painful, and it can be difficult to determine the accurate dose level of insulin. Administering too much or too little insulin poses its own health risks.
The new, injectable nano-network is composed of a mixture containing nanoparticles with a solid core of insulin, modified dextran and glucose oxidase enzymes. When the enzymes are exposed to high glucose levels they effectively convert glucose into gluconic acid, which breaks down the modified dextran and releases the insulin. The insulin then brings the glucose levels under control. The gluconic acid and dextran are fully biocompatible and dissolve in the body.
Each of these nanoparticle cores is given either a positively charged or negatively charged biocompatible coating. The positively charged coatings are made of chitosan (a material normally found in shrimp shells), while the negatively charged coatings are made of alginate (a material normally found in seaweed).
When the solution of coated nanoparticles is mixed together, the positively and negatively charged coatings are attracted to each other to form a "nano-network." Once injected into the subcutaneous layer of the skin, the nano-network holds the nanoparticles together and prevents them from dispersing throughout the body. Both the nano-network and the coatings are porous, allowing blood ? and blood sugar ? to reach the nanoparticle cores.
"This technology effectively creates a 'closed-loop' system that mimics the activity of the pancreas in a healthy patient, releasing insulin in response to glucose level changes," Gu says. "This has the potential to improve the health and quality of life of diabetes patients."
Gu's research team is currently in discussions to move the technology into clinical trials for use in humans.
