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.

Remains of man in armour found at "Pompeii of Japan"

TOKYO: The remains of a high-caste man wearing armour who was buried by hot ash -- possibly as he tried to calm the wrath of an erupting volcano -- have been found in an area known as the "Pompeii of Japan".

Archaeologists say they have unearthed the well-preserved body of a sixth-century man who had apparently turned to face a flow of molten rock as it gushed through his settlement.

"Under normal circumstances, you would flee if pyroclastic flows are rushing toward you and bringing waves of heat. But this person died facing it," said Shinichiro Ohki, of Gunma Archaeological Research Foundation.

"Maybe, if he were someone of a high position, he might have been praying, or doing something in the direction of the volcano and attempting to appease its anger," Ohki told AFP on Monday.

The remains, along with a part of an infant's skull, were found in the Kanai Higashiura dig in Gunma prefecture, roughly 110 kilometres (70 miles) northwest of Tokyo, at the site of the volcanic Mount Haruna.

The find comes from an area known to enthusiasts as the "Pompeii of Japan" a reference to the Roman city near modern-day Naples buried by the eruption of Mount Vesuvius in 79 AD.

The body is clad in a relatively sophisticated kind of armour made by craftsmen who bound small iron plates with thin leather strips, which would have represented the latest technological import from the Korean Peninsula.

It may have been brought to Japan after the practice of horse riding was introduced in the late fifth century, Ohki said, adding that the armour was much more sophisticated than the single-plate type common in the period.

"It indicates the person wearing it was someone of a high position, like a regional leader," Ohki told AFP, adding studies would be carried out to see if the man was related to occupants of ancient tombs dotting the region.

Archaeologists will also examine the bones to determine whether the man and the child were related.

"If possible, we would like to study their DNA. Were they related? Why and how did they die there?" Ohki said.

Samsung loses bid for new trial after Apple's $1B verdict

A federal judge today denied Samsung's request for a new trial against based on allegations of jury misconduct.

The South Korean electronics giant had asked that Apple's billion-dollar verdict be thrown out and the case be heard again, arguing it was tainted by the jury foreman's failure to disclose previous litigation with Seagate Technology, a company in which Samsung is a major investor, as well as an alleged bias made evident by statements made to the media after the verdict.

In seeking to have an August 24 verdict overturned that found Samsung liable for about $1.05 billion in damages arising from software patents on mobile devices, Samsung argued that jury foreman Velvin Hogan was deliberately dishonest during jury questioning. Samsung said Hogan should have revealed to the judge during jury selection that he had been sued by Seagate -- his former employer -- which led to his filing for personal bankruptcy in 1993.

"Samsung has a substantial strategic relationship with Seagate, which culminated last year in the publicized sale of a division to Seagate in a deal worth $1.375 billion, making Samsung the single largest direct shareholder of Seagate," the company said in its October motion. "Mr. Hogan's failure to disclose the Seagate suit raises issues of bias that Samsung should have been allowed to explore in questioning."

Samsung also pointed to statements made by Hogan in a post-verdict interviews with Reuters in which he said "the jury 'wanted to send a message to the industry at large that patent infringing is not the right thing to do, not just Samsung,'" and that the "message [the jury] sent was not just a slap on the wrist."

However, Lucy Koh, the U.S. District Court judge presiding over the patent case, noted that anything Hogan said about legal standards used during deliberations, or the jurors' mental process, were barred by federal evidence rules. The 20-page judgment (see below) was part of a pair of rulings Koh handed down late this evening. She also denied Apple's bid to ban a number of Samsung's devices from sale in the U.S.

"Even if the standards related by Mr. Hogan were completely erroneous, those statements would still be barred, by Federal Rule of Evidence 606(b) and cannot be considered in deciding whether to hold an evidentiary hearing," Koh said.

In regards to the disclosure issue, Koh also blamed Samsung for not asking Hogan the proper questions to reveal any alleged bias against Seagate.

"Samsung could have uncovered the Seagate lawsuit, or at least Mr. Hogan's feelings regarding Seagate, had it exercised reasonable diligence in questioning Mr. Hogan during its allotted time in voir dire," she said. "Moreover, even without asking Mr. Hogan directly, Samsung could have exercised reasonable diligence outside of trial and could have discovered the lawsuit by requesting the bankruptcy file, exactly as Samsung did later, when it became motivated to do so."

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

The orders represent the first major ones to come out of the court since the trial wrapped up in August. Still expected is a ruling from Koh that could change the damages tally. During the three and a half hour long hearing earlier this month, Apple made its bid to increase damages while Samsung predictably argued to lower them."

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.

AIG moves to sell final shares in AIA

HONG KONG: US insurance giant American International Group (AIG) will sell its remaining stake in Asian insurer AIA, in a deal that could raise up to $6.5 billion.

The sale will mark AIG's total exit from AIA after the US insurer, which was bailed out by Washington during the financial crisis, sold two-thirds of the unit in a Hong Kong listing in 2010 to help repay the financial aid.

The Hong Kong initial public offering in 2010 raised US$20.5 billion, making it one of the world's biggest.

AIG, which holds 13.69 per cent in AIA, started selling 1.65 billion shares at a price range of HK$29.65-HK$30.65 ($3.82-$3.95), Dow Jones Newswires said, quoting a term sheet.

In a short statement AIA said trading in it had been suspended in Hong Kong on Monday pending the potential sale by AIG on a "significant portion" of its stake.

AIA said it expects the trading to resume no later than Tuesday.

AIG has sold off assets as it restructured itself back to a path of profitability, and raising money to repay the $182 billion bailout it received from the US government four years ago.

It has sold AIA shares twice this year, raising a total of $8 billion.

The move also comes a week after the US Treasury sold off all of its remaining shares in AIG, earning the government $7.6 billion from the sale and taking the government's net profit on the AIG bailout to $22.7 billion.

Suspected security hole found in many Samsung devices

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 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."
