Fungal frog killer hops into crayfish

Crayfish are vulnerable to the same fungus that is killing frogs all over the world. The discovery helps explain how the disease spreads even after all the amphibians in an area have been wiped out. Worryingly, chemicals released by the fungus may alone be enough to kill.

Taegan McMahon of the University of South Florida, Tampa, and colleagues discovered infected crayfish in field surveys in Louisiana and Colorado. They found that up to 29 per cent of the animals carried the chytrid fungus Batrachochytrium dendrobatidis. Lab studies proved that crayfish can become infected and die, the first time this has been shown in non-amphibians.

Infected crayfish can pass the disease to tadpoles, and crayfish exposed to water from which the fungus had been filtered still died. McMahon says the distribution of crayfish around the world may explain why the fungus is so widespread.

She adds that it is "is certainly possible" that other invertebrates might carry the fungus. Her team are currently investigating this and are working on possible ways to stop the spread of the toxin.

"It's very compelling, their evidence for crayfish as a disease vector and for a toxic effect secreted in the water," says Trenton Garner at London's Institute of Zoology.

Indonesia blames pilot error for plane crash that killed 45

JAKARTA: Indonesian investigators blamed pilot error on Tuesday for a Sukhoi Superjet crash that killed all 45 onboard an exhibition flight that slammed into a Javanese volcano in May.

The National Transport Safety Committee (KNKT) found that the terrain awareness and warning system (TAWS) was functioning and that the pilot had switched it off before the crash.

"The TAWS had sent a 'terrain ahead' warning before the crash, followed by six 'avoid terrain' warnings. The pilot in command switched the TAWS off as he assumed there was a database problem," KNKT chief Tatang Kurniadi said.

He said there was a "diversion of attention" in the cockpit before the Sukhoi Superjet 100 crashed into the 7,200-foot (2,200-metre) dormant Mount Salak volcano.

"The crash could have been avoided if a recovery action was carried out within 24 seconds from the first warning," he told reporters.

The flight was scheduled to be a 40-minute hop to showcase the new Russian plane to prospective buyers in Indonesia, where the aviation industry is booming.

The Superjet accident was taken as a blow to the Russian aviation industry, which was hoping the twin-engine plane, the first new civilian aircraft built in post-Soviet Russia, would improve its image.

Celebrity hacker gets 10 years prison for e-mail hack

The man targeted in "Operation Hackerazzi" is now behind bars.

Hacker Christopher Chaney was sentenced to 10 years in prison today by U.S. District Judge James Otero, according to the Associated Press. Chaney pled guilty to hacking into dozens of celebrities' e-mail accounts and posting their private information on the Internet. Among his victims were Mila Kunis, Scarlett Johansson, Christina Aguilera, Simone Harouche, and Renee Olstead.

"It's hard to fathom the mindset of a person who would accomplish all of this," Otero said, according to the Associated Press. "These types of crimes are as pernicious and serious as physical stalking."

Chaney, 35 of Jacksonville, Fla., was nabbed last year following an 11-month investigation that federal officials named "Operation Hackerazzi." After the bust, Chaney initially pled not guilty, but he later struck a plea deal and ended up agreeing to nine counts, including identity theft, wiretapping, and unauthorized access of protected computers. He also agreed to surrender his computers, external drives, and cell phone.

More than 50 victims from the entertainment industry were connected with the case, but only a handful agreed to be identified by name with the hope of garnering awareness about online information theft. Chaney admitted to hacking into their accounts, obtaining private e-mails and confidential documents, publicizing their personal information, and sending photos to two celebrity Web sites. Some of the photos of Johansson were nude photos she took privately to send to her then-husband Ryan Reynolds.

Chaney gained access to the accounts by using the "Forgot your password?" feature in their e-mail accounts. He then would reset the passwords by answering security questions from public information he found by searching the Web. According to his plea agreement, Chaney received thousands of e-mails from the victims' accounts.

According to the Associated Press, Otero heard a videotaped statement from Johansson, in which she said, "I have been truly humiliated and embarrassed. I find Christopher Chaney's actions to be perverted and reprehensible."

Chaney faced up to 60 years in prison and prosecutors fought to get him at least six. Otero ruled to give him ten years because he believed Chaney would not control his behavior and showed a "callous disregard" for his actions, according to the Associated Press. The judge also ruled that Chaney will get three years of supervised probation after he serves his time.

GRAIL Mission Goes Out With a Bang

Jane J. Lee

On Friday, December 14, NASA sent their latest moon mission into a death spiral. Rocket burns nudged GRAIL probes Ebb and Flow into a new orbit designed to crash them into the side of a mountain near the moon's north pole today at around 2:28 p.m. Pacific standard time. NASA named the crash site after late astronaut Sally Ride, America's first woman in space.

Although the mountain is located on the nearside of the moon, there won't be any pictures because the area will be shadowed, according to a statement from NASA' Jet Propulsion Laboratory in California.

Originally sent to map the moon's gravity field, Ebb and Flow join a long list of man-made objects that have succumbed to a deadly lunar attraction. Decades of exploration have left a trail of debris intentionally crashed, accidentally hurtled, or deliberately left on the moon's surface. Some notable examples include:

Ranger 4 - Part of NASA's first attempt to snap close-up pictures of the moon, the Ranger program did not start off well. Rangers 1 through 6 all failed, although Ranger 4, launched April 23, 1962, did make it as far as the moon. Sadly, onboard computer failures kept number 4 from sending back any pictures before it crashed. (See a map of all artifacts on the moon.)

Fallen astronaut statue - This 3.5-inch-tall aluminum figure commemorates the 14 astronauts and cosmonauts who had died prior to the Apollo 15 mission. That crew left it behind in 1971, and NASA wasn't aware of what the astronauts had done until a post-flight press conference.

Lunar yard sale - Objects jettisoned by Apollo crews over the years include a television camera, earplugs, two "urine collection assemblies," and tools that include tongs and a hammer. Astronauts left them because they needed to shed weight in order to make it back to Earth on their remaining fuel supply, said archivist Colin Fries of the NASA History Program Office.

Luna 10 - A Soviet satellite that crashed after successfully orbiting the moon, Luna 10 was the first man-made object to orbit a celestial body other than Earth. Its Russian controllers had programmed it to broadcast the Communist anthem "Internationale" live to the Communist Party Congress on April 4, 1966. Worried that the live broadcast could fail, they decided to broadcast a recording of the satellite's test run the night before—a fact they revealed 30 years later.

Radio Astronomy Explorer B - The U.S. launched this enormous instrument, also known as Explorer 49, into a lunar orbit in 1973. At 600 feet (183 meters) across, it's the largest man-made object to enter orbit around the moon. Researchers sent it into its lunar orbit so it could take measurements of the planets, the sun, and the galaxy free from terrestrial radio interference. NASA lost contact with the satellite in 1977, and it's presumed to have crashed into the moon.

Conn. Kids Laid to Rest: 'Our Hearts Are With You'

Visibly shaken attendees exiting the funeral today for 6-year-old Noah Pozner, one of 20 children killed in the Connecticut school massacre last week, said they were touched by a story that summed up the first-grader best.

His mother, Veronique, would often tell him how much she loved him and he'd respond: "Not as much as I [love] you," said a New York man who attended the funeral but was not a member of the family.

Noah's family had been scheduled to greet the public before the funeral service began at 1 p.m. at the Abraham L. Green & Son Funeral Home in Fairfield, Conn. The burial was to follow at the B'nai Israel Cemetery in Monroe, Conn. Those present said they were in awe at the composure of Noah's mother.

Rabbi Edgar Gluck, who attended the service, said the first person to speak was Noah's mother, who told mourners that her son's ambition when he grew up was to be either a director of a plant that makes tacos -- because that was his favorite food -- or to be a doctor.

Outside the funeral home, a small memorial lay with a sign reading: "Our hearts are with you, Noah." A red rose was also left behind along with two teddy bears with white flowers and a blue toy car with a note saying "Noah, rest in peace."

Sandy Hook Victims: Jack Pinto's Funeral Held Watch Video

First Sandy Hook Shooting Victims to Be Buried Watch Video

The funeral home was adorned with white balloons as members of the surrounding communities came also to pay their respects, which included a rabbi from Bridgeport. More than a dozen police officers were at the front of the funeral home, and an ambulance was on standby at a gas station at the corner.

U.S. Sen. Richard Blumenthal, U.S. Rep. and Sen.-Elect Chris Murphy and Gov. Dannel P. Malloy, all of Connecticut, were in attendance, the Connecticut Post reported.

Noah was an inquisitive boy who liked to figure out how things worked mechanically, The Associated Press reported. His twin sister, Arielle, was one of the students who survived when her teacher hid her class in the bathroom during the attack.

CLICK HERE for a tribute to the shooting victims.

The twins celebrated their sixth birthday last month. Noah's uncle Alexis Haller told the AP that he was "smart as a whip," gentle but with a rambunctious streak. He called his twin sister his best friend.

"They were always playing together, they loved to do things together," Haller said.

The funeral for Jack Pinto, 6, was also held today, at the Honan Funeral Home in Newtown. He was to be buried at Newtown Village Cemetery.

Jack's family said he loved football, skiing, wrestling and reading, and he also loved his school. Friends from his wrestling team attended his funeral today in their uniforms. One mourner said the message during the service was: "You're secure now. The worst is over."

Family members say they are not dwelling on his death, but instead on the gift of his life that they will cherish.

The family released a statement, saying, Jack was an "inspiration to all those who knew him."

"He had a wide smile that would simply light up the room and while we are all uncertain as to how we will ever cope without him, we choose to remember and celebrate his life," the statement said. "Not dwelling on the loss but instead on the gift that we were given and will forever cherish in our hearts forever."

Jack and Noah were two of 20 children killed Friday morning at Sandy Hook Elementary School in Newtown, Conn., when 20-year-old Adam Lanza sprayed two first-grade classrooms with bullets that also killed six adults.

Zebrafish made to grow pre-hands instead of fins

PERHAPS the little fish embryo shown here is dancing a jig because it has just discovered that it has legs instead of fins. Fossils show that limbs evolved from fins, but a new study shows how it may have happened, live in the lab.

Fernando Casares of the Spanish National Research Council and his colleagues injected zebrafish with the hoxd13 gene from a mouse. The protein that the gene codes for controls the development of autopods, a precursor to hands, feet and paws.

Zebrafish naturally carry hoxd13 but produce less of the protein than tetrapods - all four-limbed vertebrates and birds - do. Casares and his colleagues hoped that by injecting extra copies of the gene into the zebrafish embryos, some of their cells would make more of the protein.

One full day later, all of those fish whose cells had taken up the gene began to develop autopods instead of fins. They carried on growing for four days but then died (Cell, DOI: 10.1016/j.devcel.2012.10.015).

"Of course, we haven't been able to grow hands," says Casares. He speculates that hundreds of millions of years ago, the ancestors of tetrapods began expressing more hoxd13 for some reason and that this could have allowed them to evolve autopods.

Testing time for China's migrant millions

BEIJING: Dozens of frustrated parents crowded into a Beijing office, surrounding an education official and brandishing copies of the constitution to demand their children be allowed to take an exam.

Mothers and fathers around the world fight to send their children to the best schools they can, in the hopes of drastically improving their futures.

But China's migrant families are victims of a decade-old residency system that denies urban incomers equal access to advantages from jobs and healthcare to the right to buy a home or car -- and education.

Chinese university admission is based on a single test, the "gaokao".

Cities such as Beijing that host China's best universities -- and large incomer populations -- only allow those with official residency permits, or "hukou", to take their exam and benefit from preferential quotas for places.

Around a third of the capital's 20 million population are migrants, but many of their families become split by rules requiring their children to go to their "home" provinces -- even if they have never lived there -- sometimes for years, to study for and take the test, which varies by location.

Even then, because of the quota system they will have to score higher to win places at top schools.

"Either you let the country share in your education resources or you accept the reality that outsiders are stuck in your education gutter," said Du Guowang, a 12-year Beijing resident from Inner Mongolia.

He and dozens of parents packed Beijing's education bureau each week hoping -- in vain -- it would let their children take next year's exam. But registration closed last week.

"This will directly affect their studies and their future prospects so of course it's unfair," said Xu Zhiyong, a prominent legal activist who has assisted the parents.

Over the past three decades more than 230 million people -- four times the entire population of Britain -- have moved to China's cities in a phenomenal mass migration.

The hukou system restrictions date back to 1958, when the government sought, among its many controls, to designate where people should farm in rural areas, and work or live for those in towns.

It has loosened the rules in recent decades to encourage urbanisation, and acknowledges the need to better accommodate newcomers -- especially as resentment mounts over China's widening rural-urban inequality.

At a key gathering of the ruling Communist Party last month, President Hu Jintao urged officials to "accelerate" hukou reform and work to "ensure that all permanent urban residents have access to basic urban public services".

But bigger cities are less willing to share residency or benefits, fearing doing so would burden their already strained resources and spur a new influx.

Some point to congested roads and overcrowded hospitals to argue that cities cannot handle larger loads.

But critics say the system is discriminatory.

Full reform would need years, but should begin sooner to defuse resentment, said Wang Zhenyu, deputy director of a public policy research centre at China University of Political Science and Law.

"From the basics like education and healthcare to social security to employment to buying a home or car, hukou-based discrimination covers every aspect," he said, "Your hukou will affect you your entire life."

Despite years of lobbying national and city education officials, the migrant parents in Beijing have received noncommittal answers -- along with occasional warnings. Their website, where they posted their demands, stopped working recently.

"Whatever we ask, it's always: 'We are studying the matter and are not ready to respond'," Du said of the official who usually receives them, "We have memorised his words."

The national education ministry has urged local governments to address the issue, and less-competitive areas have agreed to accept outside test-takers, but the capital, with its highly prized schools, has yet to act.

A Beijing education bureau official told AFP to wait for any policy announcements, adding that the office was open to parents once a week for a few hours to let them present their case.

But a mother, who wanted to be identified only by her online name "Hu Yang", said her daughter's teacher sent her a message a few weeks ago to stop making trouble.

She said she told her daughter: "I'm not making trouble for you to be able to go to school. It's for all children fighting for the right for equal education," she said.

"When they grow up they will contribute to society and to the country."

Josh Miller/CNET)

A suspected security hole affecting a handful of Samsung smartphones could give apps access to user data and leave the handset vulnerable to malicious apps and bricking, according to a developer.

The vulnerability, which was discovered and detailed by an XDA member with the handle "alephzain," lies in Exynos 4, the ARM-based system-on-chip typically found in Samsung smartphones and
tablets. Alephzain developed an exploit he said bypasses the system permissions, allowing any app to extract data from the device's RAM or inject malicious code into the kernel.

Alephzain said that he stumbled upon the vulnerability while trying to find a new way to root his Galaxy S3, but that the exploit affects the Galaxy S2,
Galaxy Note, and Meizu MX as well. However, the
Nexus 10 is unaffected as it uses the Exynos 5 chip.

"The good news is we can easily obtain root on these devices and the bad is there is no control over it," alephzain writes.

CNET has contacted Samsung for comment for comment and will update this report when we learn more.

The aurora borealis, also known as the northern lights, illuminates the Arctic sky in a recent picture by National Geographic photographer Mike Theiss.

A storm chaser by trade, Theiss is in the Arctic Circle on an expedition to photograph auroras, which result from collisions between charged particles released from the sun's atmosphere and gaseous particles in Earth's atmosphere.

After one particularly amazing show, he wrote on YouTube, "The lights were dancing, rolling, and twisting, and at times looked like they were close enough to touch!" (Watch his time-lapse video of the northern lights.)

Obama: Nation Faces 'Hard Questions' After Shooting

President Barack Obama said at an interfaith prayer service in this mourning community this evening that the country is "left with some hard questions" if it is to curb a rising trend in gun violence, such as the shooting spree Friday at Newtown's Sandy Hook Elementary School.

After consoling victims' families in classrooms at Newtown High School, the president said he would do everything in his power to "engage" a dialogue with Americans, including law enforcement and mental health professionals, because "we can't tolerate this anymore. These tragedies must end. And to end them we must change."

Sandy Hook Elementary Shooting: Remembering the Victims Watch Video

The president was not specific about what he thought would be necessary and did not even use the word "gun" in his remarks, but his speech was widely perceived as prelude to a call for more regulations and restrictions on the availability of firearms.

The grieving small town hosted the memorial service this evening as the the nation pieces together the circumstances that led to a gunman taking 26 lives Friday at the community's Sandy Hook Elementary School, most first graders.

"Someone once described the joy and anxiety of parenthood as the equivalent of having your heart outside your body all of the time, walking around," he said, speaking of the joys and fears of raising children.

"So it comes as a shock at a certain point when you realize no matter how much you love these kids you can't do it by yourself," he continued. "That this job of protecting kids and teaching them well is something we can only do together, with the help of friends and neighbors, with the help of a community, and the help of a nation."
