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.

Football: Singapore, Thailand vie for record fourth title

SINGAPORE: Singapore and Thailand will vie for the honour of becoming Southeast Asia's first four-time champions when the AFF Suzuki Cup final gets under way on Wednesday.

Both teams have won the title three times, during a period in which they shared it for the first six editions, and they are reunited in the two-legged final after both failed to reach the semis at the last tournament in 2010.

But two years after those disappointing campaigns, normal service has been resumed as they topped their respective groups before battling through tricky semi-finals to reach the final once again.

The Thais have done it in impressive fashion, winning all of their group games against the Philippines, Myanmar and Vietnam before disposing of defending champions Malaysia 3-1 on aggregate in the last four.

The "War Elephants" have not won the regional title in a decade but Winfried Schaefer's vibrant side will be favourites after netting 12 times in five games with striker Teerasil Dangda bagging a tournament-leading five goals.

And in Datsakorn Thonglao, they have a talented and combative midfielder who is determined to lift the title after finishing with runners-up medals in 2007 and 2008.

"I have never been on the winning side in the AFF Suzuki Cup. It is a gap in my career. I want to put that right this year," said the 28-year-old.

Datsakorn will be gunning to avenge the loss to Singapore in the 2007 final when Khairul Amri's thunderbolt with nine minutes left in the second leg gave the Lions a 3-2 aggregate victory.

Amri has been hobbled by a series of injuries in the past four years but he netted the only goal over two legs in a hard-fought semi-final victory against the Philippines.

That followed a group stage in which Singapore stunned neighbours Malaysia 3-0 and lost 1-0 to Indonesia, before they came from two goals down to beat unfancied Laos 4-3.

Captain Shahril Ishak has led by example by scoring four goals while 42-year-old Aleksandar Duric, set to retire after the tournament, became the competition's oldest goal-scorer when he found the net against Malaysia.

"Like us, Thailand have a good mixture of old and young players and I think that it will be a great final with the two best teams playing for the most prestigious trophy in Southeast Asian football," said the veteran striker.

"For me, playing my last game at the Jalan Besar Stadium for the national team will be a special moment for me. I have two games left and I will be enjoying every moment especially knowing that it is the final."

The first leg will be played on the artificial pitch of Singapore's Jalan Besar venue on Wednesday, with the return game at Bangkok's Supachalasai Stadium on Saturday.

More details about Newtown school gunman emerge

NEWTOWN, Conn. -- Like a lot of people who interacted with Lanza, Dot Stansy said he was "just quiet"

"On one side, he did something unspeakable, but on the other, that's not how I remember him," Stansy said. "I remember him as the nice kid that, you know, I sat near to in class. We'd joked, he'd laugh, that kind of thing."

"We were all hanging out outside of class afterwards one night, and he walked by and we were like, 'Hey, do you want to grab a drink with us?' And he said, 'No, I can't, I'm 17.'"

Lanza was also being home-schooled at the time.

He took seven college-level courses between the summers of 2008 and 2009, receiving several As in computer classes and also one in American history. His overall GPA was 3.26.

Dot Stasny remembers meeting Adam Lanza's mother.

"[She] introduced herself, said he was sick, asked where the classroom was, and when we walked in, she was getting his assignments from the teacher," Stansy said.

Nancy Lanza's friends, told CBS News' Scott Pelley on "60 Minutes" that she told them Adam had Asperger's syndrome and taking care of him was a full-time job.

"I mean, I know he was on he was on medication and everything, but she home-schooled him at home cause he couldn't deal with the school classes sometimes," Louise said. "So she just home-schooled Adam at home. And that that was her life."

Ryan Kraft, who babysat for the Lanza's when Adam was just about 10 years old, got a glimpse of how difficult he could be.

"I received instructions from Nancy to always supervise Adam at all times and to never turn my back on him," Kraft said.

Adam Lanza's parent divorced in 2009. CBS News spoke to a mediator in that divorce, who said his parents seemed to love him and only wanted the best for him.

Newtown Boy Remembered as 'Old Soul'

Dec 17, 2012 6:02pm

Though he was only in first grade, Daniel Barden was very much an “old soul,” his family said today.  He was one of the 20 children who died Friday at Sandy Hook Elementary School in Newtown, Conn.

At the age of 4, he displayed an empathy for others remarkable for a child so young.  It didn’t go unnoticed — teachers chose Daniel to be paired with a special education student at his school.

His mother, Jackie Barden, said she was always struck by “how unusual he was.”

“Our neighbors always said, ‘He’s like an old soul,’” Barden said during an interview on “Katie.”

He carried that kindness with him as he got older.

“He would hold doors open for adults all the time,” said his father, Mark Barden.

He laughed, remembering the times he’d be “halfway” across a parking lot and see his son still holding a door for strangers.

“Our son had so much love to give to this world,” Barden said. “He was supposed to have a whole lifetime of bringing that light to the world.”

Complete Coverage: Sandy Hook Elementary School Shooting

Daniel had two older siblings, James, age 12, and Natalie, age 10, who doted on their little brother.

“He was just so sweet and kind and thoughtful,” James said.

On Friday, 7-year-old Daniel, who was one of the 20 young victims at Sandy Hook Elementary School, woke up early.  He played foosball with his mother.

As usual, Daniel won, she said. The score was 10 to 8.

His father also taught him how to play “Jingle Bells” on the piano that morning.

“We did a lot in that half hour,” he said.

A celebration of Daniel’s life will be held Tuesday at St. Rose of Lima Catholic Church. A funeral is scheduled for Wednesday.

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.

N. Korea mourns late leader

SEOUL: North Korea on Monday mourned the death one year ago of leader Kim Jong-Il, with its rocket scientists taking pride of place at a special memorial ceremony led by his son and successor Kim Jong-Un.

Kim Jong-Il died of a heart attack on December 17, 2011, although his death was only announced two days later.

Monday's ceremony, attended by hundreds of top party and military cadres, was held in the Kumsusan Palace of the Sun in Pyongyang, which houses the embalmed bodies of Kim Jong-Il and his father and founding president Kim Il-Sung.

In the city's main square, people left floral tributes at the foot of giant statues of the two Kims, with state media saying at least 750,000 mourners had paid their respects on Sunday alone.

The official mourning -- broadcast live on state TV -- saw Kim Jong-Un and his wife Ri Sol-Ju lead rows of officials in bowing deeply to two giant statues of his father and grandfather inside the memorial hall.

The stone-faced officials clad in black were led by goose-stepping soldiers carrying a big floral tribute with a ribbon message reading, "The great comrades Kim Jong-Il and Kim Il-Sung stay with us forever."

A group of scientists who worked on the North's successful long-range rocket launch last week were among the first to pay tribute.

"These are scientists who made great contributions to the successful launch of our Kwangmyongsong-3 satellite and helped showcase the nation's scientific technologies to the whole world," the TV announcer said.

The Kim family has ruled the isolated, impoverished but nuclear-armed nation for more than six decades with an iron fist and a pervasive personality cult.

Newtown church evacuated after phone threat

NEWTOWN, Conn. Police say there's no danger at a Connecticut church following a phoned-in threat days after 20 children and six adults were massacred at a school.

Deborah Metz, a Trumbull police officer on the scene, gave the all-clear after an hour in which armed police in SWAT gear searched the St. Rose of Lima Roman Catholic Church and adjacent buildings.

The evacuation unnerved worshipers in the wake of the worst shooting of school-age children in U.S. history.

Victims of Conn. school shooting

Brian Wallace, director of communications for Diocese of Bridgeport, said people were asked to leave shortly after the call came in during the homily.

To interrupt people trying to heal, Wallace said, is a very "tragic and difficult thing."

The St. Rose school, church and rectory were all searched. The police said they feel "very comfortable" that everything is secure.

Since Friday's shooting, the church has been open 24 hours for people to come and pray. Police say the church will be on lockdown for the rest of the day.

Wallace said the church should reopen tomorrow.

Shooter Adam Lanza, his mother and eight of the child victims attended St. Rose of Lima. It is a Roman Catholic Church with an adjacent school, which Lanza attended briefly.

It will be the site of funerals for eight of the murdered children, and possibly one of the teachers, sources told CBS News.

Anna Wood, who was inside the church, described the scene as "surreal" to CBS News.

Wood said she was from Oxford, Conn., but came to St. Rose because of the shooting, and said the church was packed, including children.

She said no one seemed scared as they left the church, and that one boy who asked why people were asked to leave was told they were in recess.
