6 Leaking Tanks Are Wash. Nuke Site's Latest Woe

Federal and state officials say six underground tanks holding a brew of radioactive and toxic waste are leaking at the country's most contaminated nuclear site in south-central Washington, raising concerns about delays for emptying the aging tanks.

The leaking materials at Hanford Nuclear Reservation pose no immediate risk to public safety or the environment because it would take perhaps years for the chemicals to reach groundwater, Washington Gov. Jay Inslee said Friday.

But the news has renewed discussion over delays for emptying the tanks, which were installed decades ago and are long past their intended 20-year life span.

"None of these tanks would be acceptable for use today. They are all beyond their design life. None of them should be in service," said Tom Carpenter of Hanford Challenge, a Hanford watchdog group. "And yet, they're holding two-thirds of the nation's high-level nuclear waste."

Just last week, state officials announced that one of Hanford's 177 tanks was leaking 150 to 300 gallons a year, posing a risk to groundwater and rivers. So far, nearby monitoring wells haven't detected higher radioactivity levels.

Inslee then traveled to Washington, D.C., to discuss the problem with federal officials, learning in meetings Friday that six tanks are leaking.

The declining waste levels in the six tanks were missed because only a narrow band of measurements was evaluated, rather than a wider band that would have shown the levels changing over time, Inslee said.

"It's like if you're trying to determine if climate change is happening, only looking at the data for today," he said. "Perhaps human error, the protocol did not call for it. But that's not the most important thing at the moment. The important thing now is to find and address the leakers."

Department of Energy spokeswoman Lindsey Geisler said there was no immediate health risk and that federal officials would work with Washington state to address the matter.

Regardless, Sen. Ron Wyden, the new chairman of the Senate Energy and Natural Resources Committee, will ask the Government Accountability Office to investigate Hanford's tank monitoring and maintenance program, said his spokesman, Tom Towslee.

The federal government built the Hanford facility at the height of World War II as part of the Manhattan Project to build the atomic bomb. The remote site produced plutonium for the bomb dropped on Nagasaki, Japan, and continued supporting the nation's nuclear weapons arsenal for years.

Today, it is the most contaminated nuclear site in the country, still surrounded by sagebrush but with Washington's Tri-Cities of Richland, Kennewick and Pasco several miles downriver.

Several years ago, workers at Hanford completed two of three projects deemed urgent risks to the public and the environment, removing all weapons-grade plutonium from the site and emptying leaky pools that held spent nuclear fuel just 400 yards from the river.

But successes at the site often are overshadowed by delays, budget overruns and technological challenges. Nowhere have those challenges been more apparent than in Hanford's central plateau, home to the site's third most urgent project: emptying the tanks.

Hanford's tanks hold some 53 million gallons of highly radioactive waste — enough to fill dozens of Olympic-size swimming pools — and many of those tanks are known to have leaked in the past. An estimated 1 million gallons of radioactive liquid has already leaked there.

First MRI movies capture fetal brain connecting up

Sandrine Ceurstemont, editor, New Scientist TV

It's the sequel to fertilisation:
the brains of unborn babies have now been imaged in action, showing how connections form.

This fMRI movie, produced by Moriah Thomason from Wayne State University in Detroit, Michigan, shows a fly-through of several fetuses in their third trimester. By comparing the scans at slightly different stages of development, Thomason was able to pinpoint when different parts of the brain wire up. "The connection strength increases with fetal age," writes Thomason.

By identifying how brain connectivity normally develops, the scans could help diagnose and treat conditions like schizophrenia and autism before birth. For more on this research, read our full-length news story, "First snaps made of fetal brains wiring themselves up".

Volkswagen says net profit up 40% in 2012

FRANKFURT: Volkswagen, Europe's biggest car manufacturer, said on Friday that its net profit zoomed ahead by more the 40 percent last year on higher vehicle sales.

VW said in a statement its net profit soared by 40.9 percent to a record 21.7 billion euros ($28.6 billion) in 2012 as revenues rose by 20.9 percent to 192.7 billion euros and deliveries to customers were up 12.2 percent at 9.276 million vehicles.

Underlying or operating profit rose by 2.1 percent to 11.51 billion euros.

The group said it would propose an increased dividend of 3.50 euros per share for 2012 compared with 3.00 euros per share a year earlier.

Looking ahead, VW said it expected to "outperform the market as a whole in a challenging environment" and deliveries to customers would increase year-on-year.

"However, we are not completely immune to the intense competition and the impact this has on business," it cautioned.

While 2013 sales revenues were expected to exceed the 2012 level, "given the ongoing uncertainty in the economic environment, our goal for operating profit is to match the prior-year level in 2013," VW said.

Despite the car manufacturer's strong 2012 performance, analysts had been expecting an even stronger gain in profits last year.

As a result, VW shares were the biggest losers on the Frankfurt stock exchange in afternoon trading, plummeting 4.26 percent while the overall market was showing a gain of 0.81 percent.

Apple users unable to access the App Store or iTunes yesterday should find those sites alive and well today.

The App Store, iTunes, iCloud, and the Mac App Store were inaccessible to many people throughout the day on Thursday, according to 9to5Mac.

Following a series of user complaints via Twitter, Apple eventually acknowledged the problem on its system status page, which indicated outages at various times for its online stores, Mail and Contacts via iCloud, and the Calendar app across different devices.

The status showed the iCloud outage ending at 4:40 p.m. But some people continued to bump into issues even beyond that point, 9to5Mac added.

Today, Apple's status page shows all of its online sites and services up and running again. But the page doesn't offer any details as to the cause of the outage.

CNET contacted Apple for comment and will update the story if the company responds.

Oldest Known Wild Bird Hatches Chick at 62

Wisdom, the oldest known wild bird, has yet another feather in her cap—a new chick.

The Laysan albatross (Phoebastria immutabilis)—62 years old at least—recently hatched a healthy baby in the U.S. Midway Atoll National Wildlife Refuge, her sixth in a row and possibly the 35th of her lifetime, according to the U.S. Geological Survey's (USGS) North American Bird Banding Program. (Related: "51-Year-Old Albatross Breaks N. American Age Record [2003].")

But Wisdom's longevity would be unknown if it weren't for a longtime bird-banding project founded by USGS research wildlife biologist Chandler Robbins.

Now 94, Robbins was the first scientist to band Wisdom in 1956, who at the time was "just another nesting bird," he said. Over the next ten years, Robbins banded tens of thousands of black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses as part of a project to study the behavior of the large seabirds, which at the time were colliding with U.S. Navy aircraft.

Robbins didn't return to the tiny Pacific island—now part of the U.S. Papahānaumokuākea Marine National Monument—until 2002, when he "recaptured as many birds as I could in hopes that some of them would be the old-timers."

Indeed, Robbins did recapture Wisdom—but he didn't know it until he got back to his office at the Patuxent Wildlife Research Center in Laurel, Maryland, and checked her band number in the database.

"That was real exciting, because we didn't think the chances of finding one that old would be that good," Robbins said Wednesday in an interview from his office at the Patuxent center, where he still works.

Albatrosses No Bird Brains

Bigger birds such as the albatross generally live longer than smaller ones: The oldest bird in the Guinness Book of Animal Records, a Siberian white crane (Leucogeranus leucogeranus), lived an unconfirmed 82 years. Captive parrots are known to live into their 80s. (See National Geographic's bird pictures.)

The Laysan albatross spends most of the year at sea, nesting on the Midway Atoll (map) in the colder months. Birds start nesting around five years of age, which is how scientists knew that Wisdom was at least five years old in 1956.

Because albatrosses defend their nests, banding them doesn't require a net or a trap as in the case of other bird species, Robbins said—but they're far from tame.

"They've got a long, sharp bill and long, sharp claws—they could do a job on you if you're not careful how to handle them," said Robbins, who estimates he's banded a hundred thousand birds.

For instance, "when you're not looking, the black-footed albatross will sneak up from behind and bite you in the seat of the pants."

But Robbins has a fondness for albatrosses, and Wisdom in particular, especially considering the new dangers that these birds face.

Navy planes are no longer a problem—albatross nesting dunes were moved farther from the runway—but the birds can ingest floating bits of plastic that now inundate parts of the Pacific, get hooked in longlines meant for fish, and be poisoned by lead paint that's still on some of Midway Atoll's buildings. (Also see "Birds in 'Big Trouble' Due to Drugs, Fishing, More.")

That Wisdom survived so many years avoiding all those hazards and is still raising young is quite extraordinary, Robbins said.

"Those birds have a tremendous amount of knowledge in their little skulls."

"Simply Incredible"

Wisdom's accomplishments have caught the attention of other scientists, in particular Sylvia Earle, an oceanographer and National Geographic Explorer in Residence, who said by email that Wisdom is a "symbol of hope for the ocean." (National Geographic News is part of the National Geographic Society.)

Earle visited Wisdom at her nest in January 2012, where she "appeared serenely indifferent to our presence," Earle wrote in the fall 2012 issue of the Virginia Quarterly Review.

"I marveled at the perils she had survived during six decades, including the first ten or so years before she found a lifetime mate. She learned to fly and navigate over thousands of miles to secure enough small fish and squid to sustain herself, and every other year or so, find her way back to the tiny island and small patch of grass where a voraciously hungry chick waited for special delivery meals."

Indeed, Wisdom has logged an estimated two to three million miles since 1956—or four to six trips from Earth to the moon and back, according to the USGS. (Related: "Albatross's Effortless Flight Decoded—May Influence Future Planes.")

Bruce Peterjohn, chief of the North American Bird Banding Program, called Wisdom's story "simply incredible."

"If she were human, she would be eligible for Medicare in a couple years—yet she is still regularly raising young and annually circumnavigating the Pacific Ocean," he said in a statement.

Bird's-Eye View

As for Robbins, he said he'd "love to get out to Midway again." But in the meantime, he's busy going through thousands of bird records in an effort to trace their life histories.

There's much more to learn: For instance, no one has ever succeeded in putting a radio transmitter on an albatross to follow it throughout its entire life-span, Robbins noted.

"It would be [an] exciting project for someone to undertake, but I'm 94 years old," he said, chuckling. "It wouldn't do much for me to start a project at my age."

Oscar Pistorius Granted Bail in Murder Case

Oscar Pistorius was granted bail today in a South African court, meaning he can be released from jail for the six to eight months before his trial for the allegedly premeditated killing of his girlfriend Reeva Steenkamp.

Magistrate Desmond Nair, in reading his lengthy decision, said, "The issue before me is whether this accused, being who is and the assets he has [here], would seek to duck and dive all over the world."
His conclusion:
"I cannot find that he is a flight risk."

Nair said, "The accused has made a case to be released on bail."

The judge also said he had to weigh whether Pistorius would be a danger to others. He noted that Pistorius has been accused of using foul language against people in arguments and once threatened to break someone's legs, but he said that was different from someone with an arrest record of violence.

"I appreciate that a person is dead, but I don't think that is enough," he said.

Nair also said he could not be influenced by the public's "shock and outrage" if Pistorius is released.

The judge's ruling came on the fourth and final day of the bail hearing for Pistorius, the Olympian accused of murdering his girlfriend on Valentine's Day.

Pistorius, who gained global acclaim for racing at the 2012 London Olympics, shot his model-girlfriend through a closed bathroom. He says he killed Reeva Steenkamp accidentally, but prosecutors alleged that he took a moment to put on his prosthetic legs, indicating that he thought out and planned to kill Steenkamp when he shot her three times through the bathroom door.

'Blade Runner' Shocker: Lead Detective Replaced Watch Video

Oscar Pistorius: Detective Facing Attempted Murder Charges Watch Video

Pistorius sobbed today in court. Barry Roux, his defense attorney, said the prosecution misinterpreted the assigning of intent, meaning that the runner's intent to shoot at a supposed intruder in his home cannot be transferred to someone else who was shot -- in this case, Steenkamp.

"He did not want to kill Reeva," Roux told the court.

PHOTOS: Paralympics Champion Charged in Killing

When Magistrate Nair, who overheard the bail hearing, asked Roux what the charges should be if Pistorius intended to kill an intruder, the defense attorney responded that he should be charged with culpable homicide.

Culpable homicide is defined in South Africa as "the unlawful negligent killing of a human being."

Roux also made light of the prosecution's argument that Pistorius is a flight risk, saying that every time the double-amputee goes through airport security, it causes a commotion. He said that Pistorius' legs need constant maintenance and he needs medical attention for his stumps.

The prosecution argued today that the onus was on Pistorius to provide his version of events, and his version was improbable.

Prosecutor Gerrie Nel also spoke of Pistorius' fame and his disability, even relating him to Wikipedia founder Julian Assange, who is now confined to Ecuador's London Embassy, where he has been granted political asylum.
"[Assange's] facial features are as well known as Mr. Pistorius' prostheses," Nel said.

Nel argued that Pistorius' prostheses do not set him apart, stating that it's no different to any other feature, and the court cannot be seen to treat people with disabilities accused of a crime, or famous people accused of crime, any differently.

Pistorius has said that in the early hours of Feb. 14 he was closing his balcony doors when he heard a noise from the bathroom. Fearing an intruder, and without his prosthetic legs on, he grabbed a gun from under his bed and fired through the closed bathroom door, he told the court.

But prosecutors say that's implausible, that the gun's holster was found under the side of the bed where Steenkamp slept, and that Pistorius would have seen she wasn't there. Prosecutors also say the angle at which the shots were fired shows Pistorius was already wearing his prosthetics when he fired.

Spinning camera gives a ball's-eye view of the game

Hal Hodson, technology reporter

The drama of that final pass is about to get a whole lot closer. A video camera built into the side of an football would normally just provide a dizzying swirl of images as the ball spirals through the air, but computer scientists at Carnegie Mellon University in Pittsburgh, Pennsylvania, and the University of Electro-Communications in Tokyo, Japan, have found a way to turn that whirling world into a steady stream of video framed on the field of play.

Project leader Kris Katani got the idea after coming across a 1938 Popular Mechanics article, in which a 16-millimetre film camera was mounted inside a balsa-wood football to record a throw from the air. Katani's method gets a much better result, capturing video at 120 frames per second and turning the spinning footage into a solid stream in a couple of minutes.

To do this, the software in the ball recognises common features of the ground below in each new frame of video. Images of the sky are discounted. It then knits the individual frames together to create a smooth sequence.

In a paper describing the ball camera, due to be presented at the Augmented Human conference in Stuttgart, Germany, next month, the group writes that the end goal is to "extend the frontiers of the spectator experienceby capturing the excitement of being on the field through the ball's first-person point of view".

Katani is confident the technique could be miniaturised and streamlined to fit unobtrusively into a US National Football League football, but suspects that the NFL's strict standards will hold the technology back in the near future. "If professional hardware were to come in, you'd be able to separate the lens from the recording device," he says, allowing for the recording device to be stored securely within the ball. "The technology is there."

International standard schools face shutdown after Indonesia court ruling

JAKARTA: Ten years ago, Indonesia set up international standard schools with the aim of producing globally-competitive students.

But some say the project was a failure... and the Constitutional Court has recently called for the schools to be disbanded, as they are now considered to be discriminatory.

Students in one of the classes are learning Chemistry... not in Bahasa Indonesia, but in English.

This is one out of over 1,300 public schools nationwide that run classes following international standards.

The project that began in 2003 was meant to groom Indonesian students to compete globally.

Besides the national curriculum, schools employ internationally-recognised curricula and set higher standards for student enrolment and teacher qualification.

Anwar Farid, Vice Principal of SMA 68 High School, said: "The standards set in the programme motivate teachers to get a Masters degree and reach a certain TOEFL score of English proficiency. It motivates teachers to reach a higher standard. The applied curriculum combines the national curriculum and the Cambridge curriculum. This enhances teachers' and students' knowledge."

In international standard classes, Science, Math, Chemistry, Physics and Biology are mostly taught in English.

Adam Abdullah, an SMA 68 high school student, said: "This is a globalisation era, we need to speak English everywhere, even in our own country."

But a recent Constitutional Court ruling will put an end to these international standard schools, as they are now considered to be unconstitutional and discriminatory.

Febri Hendri, Public Service Monitoring Division, Indonesia Corruption Watch, said: "International standard schools provoke discrimination against other schools and within the community. Discrimination comes from the government giving privilege and much financial assistance to international standard schools."

International Standard Schools or RSBI school get a block grant from the government ranging from US$20,000 to US$50,000 a year for the first three years.

They are also allowed to charge higher school fees - US$2,500 a year - that includes Cambridge curriculum books and annual exams.

Students at regular or "normal track" public schools don't have to pay any school fees.

Ridha Tobing, a SMA 68 high school student, said: "There are also bad things about maintaining this RSBI. It's making different social gaps in terms of our SMA 68 school and other schools that are non-RSBI schools. It makes us look better, more educated, and more skilful."

The Education and Culture Minister is devising a new plan to keep some of the programmes under the international standard school plan but didn't clarify how he'll be able to keep English as the primary language of instruction as it is now deemed illegal.

The Constitutional Court Chief Justice said the Ministry has until April to decide the status of the schools, but will allow international standard schools to operate normally until the end of the school year in June.

Saverin: Facebook's rapid growth is its 'biggest risk'

Facebook co-founder Eduardo Saverin.

Facebook co-founder Eduardo Saverin isn't convinced that the social network's fast-growing strategy is a good one.

Speaking at a conference in Singapore today, Saverin said that while growth is a "huge asset," it can lead to a very real problem that shouldn't be overlooked.

"The biggest risk is growing too fast," he said, according to Bloomberg, which was in attendance at the event. "When you grow too fast, it's hard to iterate, educate."

Facebook is making no secret that it wants to grow as quickly as possible. Last month, the company's CEO Mark Zuckerberg said that he planned to increase spending by 50 percent, or $1.4 billion. That came after the company boosted spending by 67 percent in the previous year. Facebook plans to spend a bulk of its cash on mobile initiatives and advertising -- two elements that will prove extremely important for future growth.

Still, there's a problem. As Wedbush analyst Michael Pachter told CNET last month, the social network needs to see revenue grow by 28 percent "just to keep net income flat" if it actually increases spending by 50 percent. And that might prove difficult.

Saverin, who netted a huge sum in Facebook's IPO, and has a net worth that exceeds $1 billion, has had his fair share of trouble with the company. Saverin years ago sued Facebook for his stake in the company. After a drawn out fight, the case was settled out of court and he was given a co-founder credit on Facebook's site.

Despite the risks, rapid growth is not something new for Facebook. The company currently has 1.1 billion active users and continues to see huge growth in several countries around the world. Perhaps that's why Facebook's plan for rapid growth isn't concerning the company -- it's the same old thing it's been dealing with since its founding.

NASA's Mars Rover Makes Successful First Drill

For the first time ever, people have drilled into a rock on Mars, collecting the powdered remains from the hole for analysis.

Images sent back from NASA's Mars rover Curiosity on Wednesday confirmed that the precious sample is being held by the rover's scoop, and will soon be delivered to two miniature chemical labs to undergo an unprecedented analysis. (Related: "Mars Rover Curiosity Completes First Full Drill.")

To the delight of the scientists, the rock powder has come up gray and not the ubiquitous red of the dust that covers the planet. The gray rock, they believe, holds a lot of potential to glean information about conditions on an early Mars. (See more Mars pictures.)

"We're drilling into rock that's a time capsule, rocks that are potentially ancient," said sampling-system scientist Joel Hurowitz during a teleconference from NASA's Jet Propulsion Laboratory in California.

A Place to Drill

The site features flat bedrock, often segmented into squares, with soil between the sections and many round gray nodules and white mineral veins.

Hurowitz said that the team did not attempt to drill into the minerals or the gray balls, but the nodules are so common that they likely hit some as they drilled down 2.5 inches (6.3 centimeters).

In keeping with the hypothesis that the area was once under water, Hurowitz said the sample "has the potential of telling us about multiple interactions of water and rock."

The drill, located at the end of a seven-foot (two-meter) arm, requires precision maneuvering in its placement and movement, and so its successful initial use was an exciting and welcome relief. The rover has been on Mars since August, and it took six months to find the right spot for that first drill. (Watch video of the Mars rover Curiosity.)

The flat drilling area is in the lower section of Yellowknife Bay, which Curiosity has been exploring for more than a month. What was previously identified by Curiosity scientists as the dry bed of a once-flowing river or stream appears to fan out into the Yellowknife area.

The bedrock of the site—named after deceased Curiosity deputy project manager John Klein—is believed to be siltstone or mudstone. Scientists said the veins of white minerals are probably calcium sulfate or gypsum, but the grey nodules remain something of a mystery.

Triumph

To the team that designed and operates the drill, the results were a triumph, as great as the much-heralded landing of Curiosity on the red planet. With more than a hundred maneuvers in its repertoire, the drill is unique in its capabilities and complexities. (Watch video of Curiosity's "Seven Minutes of Terror.")

Sample system chief engineer Louise Jandura, who has worked on the drill for eight years, said the Curosity team had made eight different drills before settling on the one now on the rover. The team tested each drill by boring 1,200 holes on 20 types of rock on Earth.

She called the successful drilling "historic" because it gives scientists unprecedented access to material that has not been exposed to the intense weathering and radiation processes that affect the Martian surface.

Mini-laboratories

The gray powder will be routed to the two most sophisticated instruments on Curiosity—the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin).

SAM, the largest and most complex instrument onboard, operates with two ovens that can heat the sample up to 1,800°F (982°C), turning the elements and compounds in the rock into gases that can then be identified. SAM can also determine whether any carbon-based organic material is present.

Organics are the chemical building blocks of life on Earth. They are known to regularly land on Mars via meteorites and finer material that rains down on all planets.

But researchers suspect the intense radiation on the Martian surface destroys any organics on the surface. Scientists hope that organics within Martian rocks are protected from that radiation.

CheMin shoots an X-ray beam at its sample and can analyze the mineral content of the rock. Minerals provide a durable record of environmental conditions over the eons, including information about possible ingredients and energy sources for life.

Both SAM and CheMin received samples of sandy soil scooped from the nearby Rocknest outcrop in October. SAM identified organic material, but scientists are still trying to determine whether any of it is Martian or the byproduct of organics inadvertently brought to Mars by the rover. (See "Mars Rover Detects Simple Organic Compounds.")

In the next few days, CheMin will be the first to receive samples of the powdered rock, and then SAM. Given the complexity of the analysis, and the track record seen with other samples, it will likely be weeks before results are announced.

The process of drilling and collecting the results was delayed by several glitches that required study and work-arounds. One involved drill software and the other involved a test-bed problem with a sieve that is part of the process of delivering samples to the instruments.

Lead systems engineer Daniel Limonadi said that while there was no indication the sieve on Mars was malfunctioning, they had become more conservative in its use because of the test bed results. (Related: "A 2020 Rover Return to Mars?")
