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.

Tarantino film latest to be pulled after US shooting

LOS ANGELES: A Hollywood premiere of notoriously violent director Quentin Tarantino's latest film "Django Unchained" was canceled Monday, the latest such response to the Connecticut school massacre.

A string of movies and TV shows have been pulled or postponed since Friday's shootings, while sporting events have held moments of silence and players have worn black armbands to honor the victims, 20 of whom were young children.

The Weinstein Company said that a premiere scheduled Tuesday in Los Angeles of "Django Unchained" - which is due to open on Christmas Day in US theaters - had been called off.

"Our thoughts and prayers go out to the families of the tragedy in Newtown, Connecticut, and in this time of national mourning we have decided to forgo our scheduled event," said a Weinstein Company spokesperson.

The studio will still hold a screening for cast and crew and their friends and families, industry daily "Variety" reported.

Tarantino is known for screen violence, in movies from 1992's "Reservoir Dogs" to 2009's "Inglorious Basterds."

In his new film, a slave-turned-bounty hunter sets out to rescue his wife from a brutal plantation owner.

The move came after the weekend premiere of Tom Cruise's latest movie, "Jack Reacher" - about a homicide investigator probing a trained military sniper who shot five random victims - was postponed.

"Our hearts go out to all those who lost loved ones," said studio Paramount, adding that it took the action "out of honor and respect for the families of the victims whose lives were senselessly taken."

Fox canceled a weekend red carpet event and after-party for "Parental Guidance" starring Bette Midler and Billy Crystal "in light of the horrific tragedy."

The studio also replaced planned broadcasts Sunday of episodes of "Family Guy" and "American Dad" to avoid any insensitivities to the massacre.

A moment of silence was observed at National Football League (NFL) games across the country Sunday to remember those killed in the normally peaceful town of Newtown, Connecticut.

While some events were canceled because of content, others did not appear to be.

PG-rated "Parental Guidance" got its parental warning for some rude humor, not for violence, according to the IMDb industry website.

Veteran crooner Barry Manilow postponed a planned Friday night show in Palm Desert, California until Sunday, saying on his website: "Perhaps this small gesture of solidarity will help support these families on this terrible day."

Celebrities were quick to join online expressions of shock and sympathy.

Pop star Justin Bieber tweeted: "My prayers go out to all those suffering in this tragedy. it's just wrong. Everyone please pray for them."

"God have mercy!!!! No one deserves this! Praying for the families of the victims of the Connecticut shooting!! What a Christmas it will be," added singer Rihanna on the micro-blogging site.

Apple loses bid for permanent ban on Samsung phones in U.S.

A U.S. District Court judge denied Apple's bid to ban a number of Samsung's devices from sale in the U.S., a little more than a week after a hearing on the matter.

In a late ruling Monday, Judge Lucy Koh -- who presided over the entire trial between the two tech giants -- denied Apple's bid for a sales ban, saying that any infringing features were just part of a larger feature set, making a sales ban too broad.

"The phones at issue in this case contain a broad range of features, only a small fraction of which are covered by Apple's patents," Koh wrote. "Though Apple does have some interest in retaining certain features as exclusive to Apple, it does not follow that entire products must be forever banned from the market because they incorporate, among their myriad features, a few narrow protected functions."

CNET has contacted both Apple and Samsung, and will update this post when we hear back.

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.

Karena Lam pregnant again

HONG KONG: Hong Kong actress Karena Lam revealed Saturday during a publicity event that she is pregnant with her second child, reported Hong Kong media.

The actress, who is married to advertisement director Steve Yuen, gave birth to their first, daughter Kayla, in 2010.

Lam expressed that she has asked actor Ekin Cheng, who was also at the event, to be her unborn child's godfather.

"We are discussing whether I can be the child's godfather, but we'll have to ask her husband first," said Cheng, adding that he hoped it will be a boy, and would teach the child martial arts if it turns out to be a boy.

"If it's a boy, I hope he is not as naughty as you," Lam quipped.

Cheng appeared very happy for his old friend, and posed like a pregnant mother in a goofy photo with her, which she promptly put up on her micro blog.

iPhone 5 sales in China surpass 2 million in first weekend

Apple's iPhone 5.

CNET)

It's been just three days since Apple's iPhone 5 launch in China and already 2 million devices have already been sold. The tech giant announced today that this latest model of its popular smartphone is selling faster than ever in the Far East country.

"Customer response to
iPhone 5 in China has been incredible, setting a new record with the best first weekend sales ever in China," Apple CEO Tim Cook said in a statement. "China is a very important market for us and customers there cannot wait to get their hands on Apple products."

The iPhone 5 went on sale on Thursday in China and even before people could get their hands on the smartphone, hundreds of thousands of online reservations were already made for the device. The device is available through carriers China Telecom and China Unicom and, as of now, it's still not being offered on China Mobile -- the country's largest carrier.

China is of huge significance for Apple, it is the company's second biggest market -- after the U.S. -- and already accounted for about 15 percent ($23.8 billion) of the company's revenue for its fiscal year that ended in September.

When the iPhone 5 first launched in the U.S. in September, its sales topped 5 million units over first weekend -- which was a million higher than the
iPhone 4S. According to analysts at investment bank Canaccord Genuity, it is expected that Apple will sell 47.5 million iPhones in the current quarter, up from its prior forecast for 45 million. However, estimates for the first quarter of 2013 have been slightly lowered -- now 46 million instead of 47.5 million -- as the earlier-than-expected China launch is most likely pulling sales into this quarter.

Besides China, the iPhone 5 will also be on sale in more than 100 other countries by the end of the month. According to Apple, this makes the iPhone 5 the fastest iPhone rollout ever.

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 Offers Newtown 'Love and Prayers of a Nation'

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."
