Distraught father sobs on 911 after kids buried in collapse

STANLEY, N.C. (AP) ? A North Carolina man tearfully begged authorities to hurry to his house to rescue his daughter and her cousin, who were buried when the walls of a 24-foot deep pit he dug on his property collapsed.

Jordan Arwood, 31, was operating a backhoe Sunday night in the pit when the walls collapsed and he called 911.

Arwood's desperate voice is heard on a recording released by the Lincoln County Sheriff's Office on Monday, when the children's bodies were recovered.

"Please hurry ... My children are buried under tons of dirt ... They're buried under tons of clay ... It fell on top of them," he said sobbing.

When the dispatcher asked him if he could see the children, Arwood said he couldn't.

"The entire wall collapsed on them. Get a crane. Get a bulldozer. Get anything you can, please," he said. "There's no way they can breathe."

As the dispatcher began encouraging him ? and with people wailing in the background ? Arwood began praying.

"Lord lift this dirt up off these children ... so the children will be alive and well ... I have to get my kids. Lord, please," he said.

The bodies of the two young cousins, 6-year-old Chloe Jade Arwood and 7-year-old James Levi Caldwell, were dug out Monday.

Later on Monday, sheriff's deputies removed firearms and a marijuana plant from Arwood's mobile home. Arwood is a felon who is not allowed to have guns. He was convicted in 2003 for possession of a controlled substance with intent to sell.

The father had been digging with a backhoe on the site Sunday, Sheriff David Carpenter said. Investigators described the pit as 20 feet by 20 feet with a sloped entrance leading down to the 24-foot bottom. The children were at the bottom of the pit retrieving a child-sized pickaxe when the walls fell in on them, Carpenter said.

The sheriff would not say what Arwood was building or whether he had any professional help. He did say that investigators would be looking into reports from neighbors that Arwood had been building some sort of protective bunker.

"They were so distraught we hope to be able to talk to them today and come up with some information on that," Carpenter said. "It's a very large hole. It would look to be something like that, but I don't know. ... We're going to find out exactly what his intentions were."

He said deputies would be speaking with county planning and zoning officials about any potential building code violations at the site.

Andrew Bryant, a planner with the Lincoln County Planning & Inspections Department, said no permits had been issued.

On the tape, Arwood said he didn't know what happened.

"They were inside the hole helping to get something and the wall collapsed," he said.

At one point, the dispatcher warned him not to put pressure on the dirt. But Arwood said he had to reach the children.

"If this was you and your children in the dirt, you'd be moving the dirt, too," he said.

Arwood's house was at the end of a gravel-covered road dotted with modular and mobile homes. It's a tight-knit rural community where neighbors sit outside on front porches and look out for each other.

When word spread about the disaster, they ran to Arwood's house and began helping. On Monday, they were somber, saying they were heartbroken for the family. They said Arwood told them it happened without warning and that he tried to grab the children, but they were just beyond his reach.

It was no secret that Arwood was digging a two-story deep hole. Neighbors said it wasn't unusual to see children in the pit when the girl's father was working there.

Neighbor Bradley Jones, who works in construction, said there was no structure to support the pit's tall dirt walls and that there was some concrete on a ledge on top of the hole.

In recent days, the hole was muddy from the rain. He said he warned his daughter, Chelsea, who babysits for the children, not to go in.

"It was dangerous. There was nothing to reinforce those walls," he said.

Chelsea said Arwood told her that he was building the structure to "protect his family" - it was going to be a bunker.

"It's so sad," she said.

China steps up response to bird flu cases

SHANGHAI, China - Cities in eastern China where an H7N9 bird flu outbreak has killed six people moved Saturday to prevent the virus from spreading by banning live poultry trade and culling fowl.

Nanjing city shut markets selling live poultry to its more than eight million residents, while Hangzhou culled birds after discovering infected quail, the official Xinhua news agency said.

Two more people were confirmed to be infected with the virus in Shanghai, state media said late Saturday, bringing to 18 the total number of cases since authorities last week announced the virus had been detected in humans.

The human infections have been confined to eastern China, with Shanghai recording eight including four deaths, and the other two fatalities in the neighbouring province of Zhejiang.

Other cases are scattered across the provinces of Jiangsu and Anhui.

Shanghai had ordered a ban on live poultry trading and markets after culling more than 20,500 birds at an agricultural market in a western suburb on Friday.

At a local market in the city centre, two live poultry booths were dark and the cages within empty, as a uniformed worker sprayed disinfectant from a tank on his back.

"People are worried," said Yan Zhicheng, a retired factory manager who like many elderly people makes a daily trip to market.

"Shanghai people eat a lot of duck and chicken. Now we can't touch them."

Shanghai has also banned live poultry from other parts of China entering the city and the sale of wild birds, including those intended as pets, the local government said in a statement on its website.

But eggs remain on sale in the city, as well as fresh and frozen poultry meat, though officials encourage people to cook them well.

Chinese authorities maintain there is no evidence of human-to-human transmission, a conclusion echoed by the World Health Organization (WHO).

State media said the government had sought to improve transparency on the disease after being accused of covering up the 2003 outbreak of Severe Acute Respiratory Syndrome (SARS), which killed about 800 people globally.

"The government's response... is completely different from 10 years ago, when information disclosure systems were not established," Wang Yukai of the Chinese Academy of Governance told Xinhua.

But some of China's outspoken Internet users remained sceptical of government assurances.

"Get out of here. If it is not infectious then what are you doing shutting live poultry markets?" said Huang Kekedou in a microblog posting.

The US Centers for Disease Control and Prevention on Friday warned of the potential risk should the virus mutate.

"This is a 'novel' (non-human) virus and therefore has the potential to cause a pandemic if it were to change to become easily and sustainably spread from person-to-person," it said in a statement, adding that has not happened.

The US government on Friday advised American citizens living in China of the cases but said no travel or trade restrictions would be applied to the country based on the current situation.

In Shanghai, residents were taking no chances, turning to traditional medicine and donning face masks.

Drugstores were running short of banlangen, a traditional Chinese medicine for colds made from the roots of the woad plant, used as a blue dye from ancient times.

"No one knows what might happen with bird flu, so they are buying it," said a clerk at the Ren Shou Tang medicine store.

The United Nations on Friday drew up a list of recommendations to try to curb the spread of H7N9 including regular hand washing, keeping animals away from living areas and avoiding eating sick animals. - Rappler.com

(AP) ? Congress returns Monday from a two-week spring recess with gun control and immigration high on the Senate's agenda.

Senators could start debating Democratic-written gun legislation before week's end. But leaders also might decide to give negotiators more time to seek a deal on expanding background checks for firearms buyers.

Passing the expanded background checks would be viewed as a victory for gun-control advocates after Democratic leaders made it clear that supporters were nowhere close to getting a majority of votes in favor of reinstituting an assault weapons ban.

Both measures have been a priority for President Barack Obama since the Dec. 14 shooting at an elementary school in Newtown, Conn. On Monday Obama travels to Connecticut to again make the case for gun legislation, with a speech at the University of Hartford.

"He's been working with both sides to try to get the strongest bill we can that has enforceable background checks," White House senior adviser Dan Pfeiffer said Sunday on ABC's "This Week."

The National Rifle Association opposes both the assault weapons ban and the expanded background checks.

Short of unanimous support in their own party, Democratic senators have been unable to strike a deal with Republicans for the votes they would need to push background check legislation through the chamber. Senate Majority Leader Harry Reid, D-Nev., might delay debate to give bargainers more time, underscoring how crucial the proposal is to the gun control drive.

"If we go to the floor, I'm still hopeful that what I call the sweet spot ? background checks ? can succeed," Sen. Chuck Schumer, D-N.Y., said Sunday, referring to the start of debate by the full Senate. "We're working hard there."

Dan Gross, president of the Brady Campaign to Prevent Gun Violence, called the measure "the most pivotal piece" of Democrats' gun legislation.

Also high on Congress' agenda is immigration, where a decisive moment is approaching.

Bipartisan groups in the House and Senate are expected to present legislation as early as this week aimed at securing the U.S. border, fixing legal immigration and granting legal status to millions who are in the United States without authorization. That will open months of debate on the politically combustible issue, with votes by the Senate Judiciary Committee expected later this month.

The House is looking at a busy, if more low-profile agenda in the coming weeks.

In its first week back, the House will consider a bill that would prevent the National Labor Relations Board from issuing rules until a dispute over administration appointees is resolved.

Among the bills that could see action in later weeks is a measure requiring the Treasury to pay principle and interest on debt held by the public if the nation's borrowing limit is reached but not extended.

Other measures would prioritize pediatric research to assist children with autism and give workers greater flexibility to choose paid time off instead of overtime pay.

Lawmakers will devote much time to the 2014 budget proposal that Obama plans to release on Wednesday. It calls for both new tax increases, which Republicans oppose, and smaller annual increases in Social Security and other government benefit programs, over the objections of many of the president's fellow Democrats.

Even with a background check deal, Senate debate on gun legislation may begin at a slow crawl with some conservatives promising delays and forced procedural votes. Sen. John McCain, R-Ariz., on Sunday urged fellow Republicans to allow debate to go forward, even as he declined to express support for a background check bill.

"I don't understand it. The purpose of the United States Senate is to debate and to vote and to let the people know where we stand," McCain said, appearing alongside Schumer on CBS' "Face the Nation."

There's a strong chance the first votes won't occur until at least mid-April.

Until Democrats come out with the final shape of their background check measure, gun control advocates nervously are tracking the private negotiations, worried their allies might cut a deal that goes too far.

"We want a vote on the issues, we don't want them watered down so they're unrecognizable," said Joshua Horwitz, executive director of the Coalition to Stop Gun Violence. "If they can't vote for it, let the American people judge them on that. Don't let a dumbed-down bill be the outcome of this."

The Senate gun legislation would toughen federal laws against illegal firearms sales, including against straw purchasers, or those who buy firearms for criminals or others barred from owning them. The legislation also would provide $40 million a year, a modest increase from current levels of $30 million, for a federal program that helps schools take safety measures such as reinforcing classroom doors.

Omitted from the bill are bans on assault weapons and high capacity ammunition magazines, both factors in the shooting at Sandy Hook Elementary School. Those bans were approved last month by the Senate Judiciary panel. Reid has said he will allow both to be offered as amendments by their sponsor, Sen. Dianne Feinstein, D-Calif., but neither seems likely to survive.

Many experts agree that the proposal with the widest potential reach is a broadening of background checks, now required only for transactions by the roughly 55,000 federally licensed firearms dealers. Proponents want to cover private sales, such as those between individuals at gun shows or online.

One major hang-up has been Democrats' insistence on retaining records of private sales, which they say is the best way to ensure background checks are actually conducted. Sen. Tom Coburn, R-Okla., a leader of conservatives in the talks, has rejected that as excessive government intrusiveness.

The system is aimed at preventing guns from going to criminals, people with severe mental problems, some drug abusers and others.

The National Rifle Association and other critics say the checks are ignored by criminals, and they fear that expanding the system could be a prelude to the government maintaining files on gun owners. Current law forbids that. The government must destroy records of the checks within a day, though gun dealers must retain information on the transactions for 20 years.

"We remain committed in our opposition to expanding a broken system," said NRA lobbyist Chris W. Cox.

Justice Department figures show that from 1994 when the system began through 2010, 118 million would-be gun buyers were checked and 2.1 million were denied firearms. Defenders say the data proves the checks prevent many dangerous people from getting weapons.

The current background check measure, by Schumer, would expand the system to cover nearly all gun transactions, with narrow exceptions that include sales involving immediate relatives such as parents and children. Even without a bipartisan deal, Schumer is expected to expand the exemptions to more relatives, people with permits to carry concealed weapons and others.

Schumer and Sens. Joe Manchin, D-W.Va., and Mark Kirk, R-Ill., have been shopping alternatives in an effort for more GOP support. Democrats are sure to need 60 votes in the 100-member chamber to win, but there are just 53 Democratic senators plus two Democratic-leaning independents.

Democrats have considered requiring background checks for all gun show and online sales, but exempt face-to-face transactions between private individuals who do not run commercial gun enterprises.

A 'light switch' in the brain illuminates neural networks

Friday, April 5, 2013

There are cells in your brain that recognize very specific places, and have that as one of their main jobs. These cells, called place cells, are found in an area behind your temple called the hippocampus. While these cells must be sent information from nearby cells to do their job, so far no one has been able to determine exactly what kind of nerve cells, or neurons, work with place cells to craft the code they create for each location. Neurons come in many different types with specialized functions. Some respond to edges and borders, others to specific locations, others act like a compass and react to which way you turn your head.

Now, researchers at the Kavli Institute for Systems Neuroscience at the Norwegian University of Science and Technology have combined a range of advanced techniques that enable them to identify which neurons communicate with each other at different times in the rat brain, and in doing so, create the animal's sense of location. Their findings are published in the 5 April issue of Science.

"A rat's brain is the size of a grape. Inside there are about fifty million neurons that are connected together at a staggering 450 billion places (roughly)," explains Professor Edvard Moser, director of the Kavli Institute. "Inside this grape-sized brain are areas on each side that are smaller than a grape seed, where we know that memory and the sense of location reside. This is also where we find the neurons that respond to specific places, the place cells. But from which cells do these place cells get information?"

The problem is, of course, that researchers cannot simply cut open the rat brain to see which cells have had contact. That would be the equivalent of taking a giant pile of cooked spaghetti, chopping it into little pieces, and then trying to figure out how the various spaghetti strands were tangled together before the pile was cut up.

A job like this requires the use of a completely different set of neural tools, which is where the "light switches" come into play.

Neurons share many similarities with electric cables when they send signals to each other. They send an electric current in one direction ? from the "body" of the neuron and down a long arm, called the axon, which goes to other nerve cells. Place cells thus get their small electric signals from a whole series of such arms.

So how do light switches play into all of this?

"What we did first was to give these nerve arms a harmless viral infection," Moser says. "We designed a unique virus that does not cause disease, but that acts as a pathway for delivering genes to specific cells. The virus creeps into the neurons, crawls up to the nucleus of the cell, and uses the nerve cell's own factory to make the genetic recipe that we gave to the virus to carry."

The genetic recipe enabled the cell to make the equivalent of a light switch. Our eyes actually contain the same kind of biological light switch, which allows us to see. The virus infection converts neurons that have previously existed only in darkness, deep inside the brain, to now be sensitive to light.

Then the researchers inserted optical fibres in the rat's brain to transmit light to the different unidentified cells that now had light switches in them. They also implanted thin microelectrodes down between the cells so they could detect the signals sent through the axons every time the light from the optical fibre was turned on.

"Now we had everything set up, with light switches installed in cells around the place cells, a lamp, and a way to record the activity," Moser said.

The researchers then turned the lights on and off more than ten thousand times in their rat lab partners, while they monitored and recorded the activity of hundreds of individual cells in the rats' grape-sized brains. The researchers did this research while the rats ran around in a metre-square box, gathering treats. As the rats explored their box and found the treats, the researchers were able to use the light-sensitive cells to figure out which cells were feeding information to the place cells as the rat's brain created the map of where the rat had been.

When the researchers put together all the information afterwards they concluded that there is a whole range of different specialized cells that together provide place cells their information. The brain's GPS ? its sense of place ? is created by signals from head direction cells, border cells, cells that have no known function in creating location points, and grid cells. Place cells thus receive both information about the rat's surroundings and landmarks, but also continuously update their own movement, which is actually independent on sensory input.

"One mystery is the role that the cells that are not part of the sense of direction play. They send signals to place cells, but what do they actually do?" wonders Moser.

"We also wonder how the cells in the hippocampus are able to sort out the various signals they receive. Do they 'listen' to all of the cells equally effectively all the time, or are there some cells that get more time than others to 'talk' to place cells?"
