Japan summons China envoy in island row

TOKYO: Tokyo summoned China's envoy Tuesday in protest after what it says was another incursion into its territorial waters around islands at the centre of a bitter dispute with Beijing.

"The foreign ministry summoned the Chinese ambassador over ships entering the waters near Senkaku islands," said a foreign ministry official, referring to a chain claimed as the Diaoyus by Beijing.

The move comes after Chinese state vessels spent much of Monday in waters around the islands and as the two sides show no sign of backing down in a dispute that has badly affected trade between Asia's two largest economies.

Two maritime surveillance boats arrived in the area shortly before 9:30 am (0130 GMT), the Japanese coastguard said, with Kyodo News reporting they had remained there for around 14 hours.

Chinese ships have repeatedly ventured into the waters, in what observers say is Beijing's bid to create a "new normal" in which Tokyo does not have effective control over the archipelago.

A Chinese government plane entered the chain's airspace in December, setting off sorties by Japanese fighter jets.

In recent weeks both countries have dispatched military planes to the region, although there have been no clashes.

But analysts say the ramping up of rhetoric and the more frequent confrontations raise the risk of an accidental armed conflict.

Alleged T-Mobile roadmap shows LTE devices arriving March 27

T-Mobile's LTE launch plans revealed?

TMO News)

T-Mobile is reportedly readying a harvest of LTE-enabled devices this spring, suggesting that T-Mobile's 4G LTE network will be operational by that time

The wireless carrier is expected to release the
BlackBerry Z10, Samsung Galaxy Exhibit, and Sonic 2.0 LTE mobile hotspot on March 27, according to a purported roadmap leaked to TMO News. A screenshot of the roadmap also lists an LTE-enabled Samsung Galaxy S3 launching either March 27 or April 3.

Pricing for the devices was not included.

T-Mobile, which does not yet currently offer 4G LTE, has said before that it will develop a 4G LTE network. It currently offers 4G (HSPA+), which it says is fast enough to be called 4G.

CNET has contacted T-Mobile for comment and will update this report when we learn more.

The BlackBerry Z10, which was announced last week, is reportedly off to a strong sales start in several countries around the world. The device runs the company's latest operating system,
BlackBerry 10, and comes with a full, 4.2-inch touch screen.

The U.K. seems to be BlackBerry's best market, according to Jefferies analyst Peter Misek. "Initial checks" had found that Carphone Warehouse, a company that sells handsets, "is seeing widespread sellouts," Misek said in a research note obtained this morning by CNET. U.K. carriers O2, Vodafone, Orange, and EE "are seeing robust demand," he said.

Space Pictures This Week: A Space Monkey, Printing a Moon Base

Illustration courtesy Foster and Partners/ESA

The European Space Agency (ESA) announced January 31 that it is looking into building a moon base (pictured in an artist's conception) using a technique called 3-D printing.

It probably won't be as easy as whipping out a printer, hooking it to a computer, and pressing "print," but using lunar soils as the basis for actual building blocks could be a possibility.

"Terrestrial 3-D printing technology has produced entire structures," said Laurent Pambaguian, head of the project for ESA, in a statement.

On Earth, 3-D printing, also known as additive manufacturing, produces a three-dimensional object from a digital file. The computer takes cross-sectional slices of the structure to be printed and sends it to the 3-D printer. The printer bonds liquid or powder materials in the shape of each slice, gradually building up the structure. (Watch how future astronauts could print tools in space.)

The ESA and its industrial partners have already manufactured a 1.7 ton (1.5 tonne) honeycombed building block to demonstrate what future construction materials would look like.

Boy Safe, Kidnapper Dead After Hidden Camera Tip

A week-long standoff in Alabama, where a retired trucker held a 5-year-old boy hostage in an underground bunker, has ended with the kidnapper dead and the child safe, according to law enforcement.

Officials had been able to insert a high-tech camera into the bunker to monitor the movements of the suspect, Richard Lee Dykes, and they had become increasingly concerned that he might act out, according to a law enforcement source with direct knowledge.

"FBI agents safely recovered the child who's been held hostage for nearly a week," FBI Special Agent Steve Richardson said at a news conference.

The agent said negotiations with Dykes "deteriorated" in the past 24 hours.

"Mr. Dykes was observed holding a gun," Richardson said. "At this point, the FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."

The boy, identified only as Ethan, "appears physically unharmed" and is being treated at a hospital, authorities said.

Dykes, 65, is dead, but officials have not yet provided details on how he died.

"Right now, FBI special agent bomb technicians are in the process of clearing the property for improvised explosive devices," the FBI said in a written statement. "When it is safe to do so, our evidence response teams, paired with state and local crime scene technicians, will process the scene."

PHOTOS: Worst Hostage Situations

Dykes allegedly shot and killed a school bus driver last week and threatened to kill all the children on the bus before taking the boy, one of the students on the bus said.

"He said he was going to kill us, going to kill us all," Tarrica Singletary, 14, told ABC News.

Dykes had been holed up in his underground bunker near Midland City, Ala., with the abducted boy for a week as police tried to negotiate with him through a PVC pipe. Police had used the talks to send the child comfort items, including a red Hot Wheels car, coloring books, cheese crackers, potato chips and medicine.

Dykes was a decorated Vietnam vet who grew up in the area. He lived in Florida until two years ago, the AP reported, and has an adult daughter, but the two lost touch years ago, neighbor Michael Creel said. When he returned to Alabama, neighbors say he once beat a dog with a lead pipe and had threatened to shoot children who set foot on his property.

Bug protects itself by turning its environment to gold

Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch.

Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic.

To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells.

"This could have potential for gold extraction," says Nathan Magarvey of McMaster University in Hamilton, Ontario, who led the team that uncovered the bugs' protective trick. "You could use the bug, or the molecules they secrete."

He says the discovery could be used to dissolve gold out of water carrying it, or to design sensors that would identify gold-rich streams and rivers.

The protective chemical is a protein dubbed delftibactin A. The bugs secrete it into the surroundings when they sense gold ions, and it chemically changes the ions into particles of gold 25 to 50 nanometres across. The particles accumulate wherever the bugs grow, creating patches of gold.

Deep purple gold

But don't go scanning streams for golden shimmers: the nanoparticle patches do not reflect light in the same way as bigger chunks of the metal – giving them a deep purple colour.

When Magarvey deliberately snipped out the gene that makes delftibactin A, the bacteria died or struggled to survive exposure to gold chloride. Adding the protein to the petri dish rescued them.

The bacterium Magarvey investigated is one of two species that thrive on gold, both identified a decade or so ago by Frank Reith of the University of Adelaide in Australia. In 2009 Reith discovered that the other species, Cupriavidus metallidurans, survives using the slightly riskier strategy of changing gold ions into gold inside its cells.

"If delftibactin is selective for gold, it might be useful for gold recovery or as a biosensor," says Reith. "But how much dissolved gold is out there is difficult to say."

Beyonce brings out Destiny's Child for Super Bowl thrill

NEW ORLEANS, Louisiana: Pop diva Beyonce thrilled the Super Bowl crowd Sunday with a pyrotechnic half-time spectacular that doubled as a much-anticipated Destiny's Child reunion.

Fireworks burst into the sky from the Superdome field just vacated by the game-leading Baltimore Ravens and lagging San Franciso 49s as the 31-year-old chart-topper took the stage with "Crazy in Love".

Blowing a kiss to the live television camera after her opening number, she looked relieved to get the much-hyped, 15-minute show underway, but the real treat came when Destiny's Child bandmates Kelly Rowland and Michelle Williams joined her on stage.

They appeared in matching Rubin Singer black leather warrior-woman bodysuits and dizzying stilettos as did an ever-growing, all-female army of dancers, with musicians cast off on the sidelines.

"Bootylicious", "Halo", and "Single Ladies (Put a Ring on It)" rounded out the greatest-hits performance with a sci-fi edge that set it apart from Madonna's hyperactive Super Bowl half-time effort last year.

"Thank you for this moment," a beaming Beyonce told the cheering crowd at the conclusion, "God bless you all."

Beyonce had promised to sing live at the Super Bowl, acknowledging that she had sung over a pre-recorded version of "The Star-Spangled Banner" at President Barack Obama's second-term inauguration on January 21.

Singing the pre-game national anthem Sunday was Alicia Keys, performing solo at a grand piano, after Jennifer Hudson and the Sandy Hook Elementary School choir from Newtown, Connecticut sang "America the Beautiful".

The school was the scene of one of the worst mass murders in US history in December when a lone young gunman cut down 20 pupils and six teachers before taking his own life. He had earlier killed his mother at their home.

Super Bowl play stopped for 34 minutes as Superdome lost power

The Superdome after a sudden power outage in the second half during Super Bowl XLVII.

Ezra Shaw/Getty Images)

As the second half got underway at the Super Bowl, old-fashioned technology got in the way of play. Power at the Superdome reportedly surged, knocking out a majority of lights as well as CBS' play-by-play announcers. According to Entergy, which supplies the power to the Superdome, the issue is on the "customer's side."

An outside power feed coming to the stadium got disrupted according to NFL officials, said CBS's announcer on the sidelines Steve Tasker. Play-by-play announcers Jim Nance and Phil Simms were off the air for more than 30 minutes. Power was restored and play resumed after a 34-minute delay.

The Twitter football fans watching the game had some fun while waiting for the game to resume:

Pictures We Love: Best of January

Photograph by Dieu Nalio Chery, AP

The magnitude 7 earthquake that struck near Port au Prince, Haiti, in January 2010 so devastated the country that recovery efforts are still ongoing.

Professional dancer Georges Exantus, one of the many casualties of that day, was trapped in his flattened apartment for three days, according to news reports. After friends dug him out, doctors amputated his right leg below the knee. With the help of a prosthetic leg, Exantus is able to dance again. (Read about his comeback.)

Why We Love It

"This is an intimate photo, taken in the subject's most personal space as he lies asleep and vulnerable, perhaps unaware of the photographer. The dancer's prosthetic leg lies in the foreground as an unavoidable reminder of the hardships he faced in the 2010 earthquake. This image makes me want to hear more of Georges' story."—Ben Fitch, associate photo editor

"This image uses aesthetics and the beauty of suggestion to tell a story. We are not given all the details in the image, but it is enough to make us question and wonder."—Janna Dotschkal, associate photo editor

Two worms, same brains – but one eats the other

IF TWO animals have identical brain cells, how different can they really be? Extremely. Two worm species have exactly the same set of neurons, but extensive rewiring allows them to lead completely different lives.

Ralf Sommer of the Max Planck Institute for Developmental Biology in Tübingen, Germany, and colleagues compared Caenorhabditis elegans, which eats bacteria, with Pristionchus pacificus, which hunts other worms. Both have a cluster of 20 neurons to control their foregut.

Sommer found that the clusters were identical. "These species are separated by 200 to 300 million years, but have the same cells," he says. P. pacificus, however, has denser connections than C. elegans, with neural signals passing through many more cells before reaching the muscles (Cell, doi.org/kbh). This suggests that P. pacificus is performing more complex motor functions, says Detlev Arendt of the European Molecular Biology Laboratory in Heidelberg, Germany.

Arendt thinks predators were the first animals to evolve complex brains, to find and catch moving prey. He suggests their brains had flexible wiring, enabling them to swap from plant-eating to hunting.
