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.

Obama moves on taxes in latest "cliff" counter-proposal

President Obama gave up Monday on his demand for higher taxes on households earning $250,000 and upped it to $400,000 while embracing smaller cost-of-living Social Security raises in a counter-proposal to House Speaker John Boehner meant to narrow differences and forge a pre-Christmas "fiscal cliff" deal.

Mr. Obama and Boehner met for nearly an hour in the Oval Office on Monday and sources familiar with the talks released specific details of the White House proposal.

Boehner aides said it brought the two sides closer but said a deal was not at hand.

"Any movement away from the unrealistic offers the President has made previously is a step in the right direction, but a proposal that includes $1.3 trillion in revenue for only $930 billion in spending cuts cannot be considered balanced," said Brendan Buck, a Boehner spokesman.

Other senior Republican aides told reporters on Capitol Hill they are not rejecting the latest White House offer, but they also said that there is not parity or balance in the White House plan and substantive issues remain unresolved. One senior aide said the issues that they are talking about are not technically difficult to resolve, but they were wary the differences might be fundamental issues that are difficult to resolve.

But the depth, specificity and fine-grain nature of discussions over policy, tax revenue and spending cuts belied the tough rhetoric from the two sides in the negotiation. Signs point to a deal before the New Year's fiscal cliff deadline -- and possibly an announcement as early as Wednesday.

Boehner's "fiscal cliff" concessions come with a price

Talks picked up genuine momentum on Friday when Boehner agreed to higher income tax rates on households earning $1 million and above. Previously, Boehner opposed all income tax increases. He also gave in on raising the debt ceiling, a vote some Republicans wanted to use as leverage against Obama in 2013. Both gestures, top White House aides said, broke the logjam.

Mr. Obama responded with big concessions of his own on Monday. He offered a $400,000 income threshold for a Clinton-era top tax bracket of 39.6 percent. Boehner had proposed that tax rate for millionaires and a total 10-year tax revenue figure of $1 trillion. Obama wants $1.2 trillion in new revenue. Both sides look for hundreds of billions in new revenue in 2013 through a tax reform process that eliminates some tax deduction and closes loopholes.

The president also wants a two-year ceasefire on raising the debt ceiling. Boehner offered one year.

In addition to disagreement on income levels for tax rates or some other way to get more revenue, the two sides have not set in stone an actual tax reform process. It sounds like they are talking about creating a new sequester-like mechanism in 2014 as incentive for both tax reform and entitlement reforms.

Speaking of entitlements, Boehner also asked the White House to increase the eligibility age for Medicare but Mr. Obama again refused. This difference could loom large as Republicans want structural cost-saving changes in Medicare in exchange for raising income tax rates.

Mr. Obama has given ground on cost-of-living adjustments to Social Security and other federal benefits, but is trying to shield Medicare. Democrats have warned Obama they might bolt if he folds on raising Medicare's eligibility age. They have been less emphatic about cost-of-living adjustments.

Other components of the president's counter-proposal include:

• $1.2 trillion in new income tax revenue with a 39.6 percent (up from 35 percent) on income of $400,000 or more.
• $1.2 trillion in spending cuts divided this way: $800 billion in cuts; $290 billion in interest savings due to lower deficits; $130 billion in cost-of-living adjustments - - with specific protections to preserve increases for economically disadvantaged beneficiaries. Because changing cost-of-living adjustments would also affect where people fell in various tax brackets, this move would raise $90 billion
• The $800 billion in cuts would come from $400 billion in savings to health care entitlements like Medicare and Medicaid; $200 billion in better tax revenue collection, increased financial transaction fees and reduced federal employee benefits.
• $200 billion in domestic discretionary -- annual spending on basic government functions - divided equally between defense and non-defense programs.
• At least $50 billion devoted next year to infrastructure spending and more in latter years - figures still subject to negotiation.
• A one-year extension of unemployment insurance benefits.

Both sides have already agreed to create long-term solutions for the annual ritual of adjusting the Alternative Minimum Tax, the reimbursement formulas for Medicare physicians and a grab-bag of pro-business tax breaks.

Obama also did not ask for an extension of the temporary 2 percent payroll tax - a priority for some Democrats.

Funding for Superstorm Sandy will be handled separately from the emerging fiscal cliff package. The Senate is considering the administration's $60.4 billion request and the White House expects swift, bipartisan approval.

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.

Updated 11:48 p.m. ET

TOPEKA, Kan. Authorities say two Kansas police officers shot outside a grocery store have died at a hospital.

Police say the 22-year-old male suspect in Sunday evening's shooting in Topeka remains at large and is believed to still be armed.

CBS affiliate WIBW-TV in Topeka reports the name of the suspect being sought is David Edward Tiscareno, a Topeka resident.

The officers were shot when they responded to a report of a suspicious vehicle near the store. The officers have been identified as 50-year-old Cpl. David Gogian and 29-year-old Officer Jeff Atherly.

A witness told WIBW the shooting happened just outside the entrance of Dillons. The witness said he heard three gun clips emptied, then heard another series of shots.

A small crowd gathered for a candlelight vigil outside police headquarters as reporters nearby were given the news of the officers' deaths.

Gogian had been with the department since September 2004 and Atherly since April 2011.

Authorities found the reported vehicle outside a house 10 blocks from the store.

Officers searched the house but didn't find the suspect.

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."
