Study: People worldwide living longer, but sicker

LONDON (AP) — Nearly everywhere around the world, people are living longer and fewer children are dying. But increasingly, people are grappling with the diseases and disabilities of modern life, according to the most expansive global look so far at life expectancy and the biggest health threats.

The last comprehensive study was in 1990 and the top health problem then was the death of children under 5 — more than 10 million each year. Since then, campaigns to vaccinate kids against diseases like polio and measles have reduced the number of children dying to about 7 million.

Malnutrition was once the main health threat for children. Now, everywhere except Africa, they are much more likely to overeat than to starve.

With more children surviving, chronic illnesses and disabilities that strike later in life are taking a bigger toll, the research said. High blood pressure has become the leading health risk worldwide, followed by smoking and alcohol.

"The biggest contributor to the global health burden isn't premature (deaths), but chronic diseases, injuries, mental health conditions and all the bone and joint diseases," said one of the study leaders, Christopher Murray, director of the Institute of Health Metrics and Evaluation at the University of Washington.

In developed countries, such conditions now account for more than half of the health problems, fueled by an aging population. While life expectancy is climbing nearly everywhere, so too are the number of years people will live with things like vision or hearing loss and mental health issues like depression.

The research appears in seven papers published online Thursday by the journal Lancet. More than 480 researchers in 50 countries gathered data up to 2010 from surveys, censuses and past studies. They used statistical modeling to fill in the gaps for countries with little information. The series was mainly paid for by the Bill & Melinda Gates Foundation.

As in 1990, Japan topped the life expectancy list in 2010, with 79 for men and 86 for women. In the U.S. that year, life expectancy for men was 76 and for women, 81.

The research found wide variations in what's killing people around the world. Some of the most striking findings highlighted by the researchers: — Homicide is the No. 3 killer of men in Latin America; it ranks 20th worldwide. In the U.S., it is the 21st cause of death in men, and in Western Europe, 57th.

— While suicide ranks globally as the 21st leading killer, it is as high as the ninth top cause of death in women across Asia's "suicide belt," from India to China. Suicide ranks 14th in North America and 15th in Western Europe.

— In people aged 15-49, diabetes is a bigger killer in Africa than in Western Europe (8.8 deaths versus 1 death per 100,000).

— Central and Southeast Asia have the highest rates of fatal stroke in young adults at about 15 cases per 100,000 deaths. In North America, the rate is about 3 per 100,000.

Globally, heart disease and stroke remain the top killers. Reflecting an older population, lung cancer moved to the 5th cause of death globally, while other cancers including those of the liver, stomach and colon are also in the top 20. AIDS jumped from the 35th cause of death in 1990 to the sixth leading cause two decades later.

While chronic diseases are killing more people nearly everywhere, the overall trend is the opposite in Africa, where illnesses like AIDS, malaria and tuberculosis are still major threats. And experts warn again shifting too much of the focus away from those ailments.

"It's the nature of infectious disease epidemics that if you turn away from them, they will crop right back up," said Jennifer Cohn, a medical coordinator at Doctors Without Borders.

Still, she acknowledged the need to address the surge of other health problems across Africa. Cohn said the agency was considering ways to treat things like heart disease and diabetes. "The way we treat HIV could be a good model for chronic care," she said.

Others said more concrete information is needed before making any big changes to public health policies.

"We have to take this data with some grains of salt," said Sandy Cairncross, an epidemiologist at the London School of Hygiene and Tropical Medicine.

He said the information in some of the Lancet research was too thin and didn't fully consider all the relevant health risk factors.

"We're getting a better picture, but it's still incomplete," he said.

Adele, Carly Rae top music; Birds rule 2012 apps

NEW YORK (AP) — It may be 2012, but it's a repeat of 2011 for Adele: Once again, she has the year's top-selling album on iTunes.

Her "21," which recently passed the 10 million mark in sales, topped the list even though it was first released in January 2011. It remained popular this year, particularly after she nabbed six Grammy Awards in February.

Coming in second was Taylor Swift's "Red," which wasn't released until October. Rounding out the top five: Mumford & Sons' "Babel," One Direction's "Up All Night" and fun.'s "Some Nights."

Carly Rae Jepsen had the song of the year with "Call Me Maybe" — and so it was also tops on iTunes, followed by Goyte's "Somebody That I Used to Know," fun.'s "We Are Young," Maroon 5's "Payphone" with Wiz Khalifa and Nicki Minaj's "Starships."

In the world of apps, "Angry Birds Space" was king of the top-paid iPhone and iPad apps, while those looking for freebies made YouTube the top iPhone app and Skype the most popular iPad app.

The top-selling movie was "The Hunger Games"; the best-selling TV show was an episode of "The Walking Dead" from season three; and the top TV series purchased for a season and a season's pass was "Downton Abbey," season two.

The erotic sensation "Fifty Shades of Grey" was the top-paid fiction book, followed by the rest of the trilogy in the next two slots. The best-selling nonfiction book was Mark Owen and Kevin Maurer's "No Easy Day," about the killing of Osama bin Laden.

The iTunes store is also playing tastemaker once again, determining its own "best of" lists. Frank Ocean was named top artist, while the Grizzly Bear's "Shields" was named best album and fun.'s "We Are Young" was named best song. Other iTunes bests: Action Movie FX was named iPhone app of year, "Breaking Bad" as best TV show and "The Avengers" as the "best blockbuster."

Illinois foreclosures up for 11th month

Foreclosure activity in Illinois posted the 11th straight year-over-year increase in November, but compared with a month earlier, filings are trending in the right direction, according to new data released Thursday.

RealtyTrac said the 13,520 properties within the state that received a foreclosure notice last month was a decrease of 9 percent from October but up 9 percent from November 2011. last month's activity, which equated to one out of every 392 homes in the state receiving a notice, gave Illinois the nation's third-highest state foreclosure rate, surpassed by only Florida and Nevada.

In the Chicago-area counties of Cook, DuPage, Kane, Kendall, Lake and Will, almost 11,000 homes received a foreclosure notice in November, a decrease of 10.5 percent from October's level of activity but up 1.6 percent from November 2011

Most of that activity was in Cook County, where about 2,299 homes received initial notices of default, another 2,651 homes were scheduled for court-ordered sales and 2,086 homes were repossessed by lenders.

Among the nation's metropolitan areas, Rockford and Chicago ranked 11th and 13th, respectively, in terms of their foreclosure rates.

Nationally, the number of homes that were repossessed by lenders and became bank-owned rose on a year-over-year basis for the first time  since October 2010, the company said. In November, more than 59,000 homes across the country were repossessed, an increase of 11 percent from October and 5 percent from November 2011.

"The drop in overall foreclosure activity in November was caused largely by a 71-month low in foreclosure starts for the month, more evidence that we are past the worst of the foreclosure problem brought about by the housing bubble bursting six years ago," said Daren Blomquist, a company vice president. "But foreclosures are continuing to hobble the U.S. housing market as lenders finally seize properties that started the process a year or two ago, and much longer in some cases."

Police: Oregon mall shooting victims identified

The gunman who killed two people and himself in a shooting rampage at an Oregon mall was 22 years old and used a stolen rifle from someone he knew, authorities said Wednesday.

Jacob Tyler Roberts had armed himself with an AR-15 semiautomatic rifle and had several fully loaded magazines when he arrived at a Portland mall on Tuesday, said Clackamas County Sheriff Craig Roberts.

The sheriff said the rifle jammed during the 22-year-old's attack, but he managed to get it working again. He later shot himself. Authorities don't yet have a motive but don't believe he was targeting specific people.

Two people — a 54-year-old woman and a 45-year-old man — were killed, and another, Kristina Shevchenko, 15, was wounded and in serious condition on Wednesday.

Roberts, wearing a hockey-style face mask, parked his 1996 green Volkswagen Jetta in front of the second-floor entrance to Macy's and walked briskly through the store, into the mall and began firing randomly, police said.

He fatally shot Steven Mathew Forsyth of West Linn and Cindy Ann Yuille of Portland, the sheriff said.

Roberts then fled along a mall corridor and into a back hallway, down stairs and into a corner where police found him dead from an apparent self-inflicted gunshot, authorities said.

People at the mall were heroic in helping get shoppers out of the building, including medical personnel who rendered aid, Roberts said.

In response to previous mass shootings elsewhere, the first arriving officers were trained to form teams and go inside instead of waiting for SWAT. Employees at the mall also received training to handle such a situation.

"This could have been much, much worse," Roberts said.

The first 911 call came at 3:29 p.m. Tuesday and officers arrived a minute later. By 3:51 p.m., all the victims and the gunman and rifle had been found. Four SWAT teams spent hours clearing the 1.4 million square-foot mall, leaving shoppers and workers to hide in fear.

Roberts rented a basement room in a modest, single-story Portland home and hadn't lived there long, said a neighbor, Bobbi Bates. Bates said she saw Roberts leave at 1:30 p.m. Tuesday wearing a dark jacket and jeans, carrying a guitar case. An occupant at the house declined to comment.

The mall Santa, Brance Wilson, was waiting for the next child's Christmas wish when shots rang out, causing the mall to erupt into chaos.

About to invite a child to hop onto his lap, Wilson instead dove for the floor and kept his head down as he heard shots being fired upstairs in the mall.

"I heard two shots and got out of the chair. I thought a red suit was a pretty good target," said Wilson, 68. Families waiting for Santa scattered. More shots followed, and Wilson crept away for better cover.

Witnesses heard the gunman saying, "I am the shooter," as he fired rounds from a semi-automatic rifle inside the Clackamas Town Center, a popular suburban mall several miles from downtown Portland.

Some were close enough to the shooter to feel the percussion of his gun.

Kayla Sprint, 18, was interviewing for a job at a clothing store when she heard shots.

"We heard people running back here screaming, yelling '911,'" she told The Associated Press.

Facebook unveils new privacy controls

SAN FRANCISCO (Reuters) - Facebook Inc began rolling out a variety of new privacy controls on Wednesday, the company's latest effort to address user concerns about who can see their personal information on the world's largest social network.

New tools introduced on Wednesday will make it easier for Facebook's members to quickly determine who can view the photos, comments and other information about them that appears on different parts of the website, and to request that any objectionable photos they're featured in be removed.

A new privacy "shortcut" in the top-right hand corner of the website provides quick access to key controls such as allowing users to manage who can contact them and to block specific people.

The new controls are the latest changes to Facebook's privacy settings, which have been criticized in the past for being too confusing.

Facebook Director of Product Sam Lessin said the changes were designed to increase users' comfort level on the social network, which has roughly one billion users.

"When users don't understand the concepts and controls and hit surprises, they don't build the confidence they need," said Lessin.

Facebook, Google Inc and other online companies have faced increasing scrutiny and enforcement from privacy regulators as consumers entrust ever-increasing amounts of information about their personal lives to Web services.

In April, Facebook settled privacy charges with the U.S. Federal Trade Commission that it had deceived consumers and forced them to share more personal information than they intended. Under the settlement, Facebook is required to get user consent for certain changes to its privacy settings and is subject to 20 years of independent audits.

Facebook's Lessin said some users don't understand that the information they post on their Timeline profile page is not the only personal information about them that may be viewable by others. Improvements to Facebook's so-called Activity Log will make it easier for users to see at a glance all the information that involves them across the social network.

Facebook also said it is changing the way that third-party apps, such as games and music players, get permission to access user data. An app must now provide separate requests to create a personalized service based on a user's personal information and to post automated messages to the Facebook newsfeed on behalf of a user - previously users agreed to both conditions by approving a single request.

The revamped controls follow proposed changes that Facebook has made to its privacy policy and terms of service. The changes would allow Facebook to integrate user data with that of its recently acquired photo-sharing app Instagram, and would loosen restrictions on how members of the social network can contact other members using the Facebook email system.

Nearly 600,000 Facebook users voted to reject the proposed changes, but the votes fell far short of the roughly 300 million needed for the vote to be binding, under Facebook's existing rules. The proposed changes also would eliminate any such future votes by Facebook users.

Williams testified he wanted to stop bounties

Former New Orleans defensive coordinator Gregg Williams testified that he tried to shut down the team's bounty system when the NFL began investigating but was overruled by interim Saints head coach Joe Vitt, according to transcripts from appeals hearings obtained by The Associated Press.

According to the transcripts, Williams said that then-assistant Vitt responded to a suggestion that the pay-for-pain setup be abandoned with an obscenity-filled speech about how NFL Commissioner Roger Goodell "wasn't going to ... tell us to ... stop doing what won us the Super Bowl. This has been going on in the ... National Football League forever, and it will go on here forever, when they run (me) out of there, it will still go on."

Williams and Vitt were among a number of witnesses whose testimony was heard by former NFL Commissioner Paul Tagliabue, who on Tuesday overturned four player suspensions in the case. Tagliabue was appointed by Goodell to handle the final round of appeals. The AP obtained transcripts of Tagliabue's closed-door hearings through a person with a role in the case.

Vitt was a Saints assistant who was banned for six games for his part in the scandal but now is filling in for head coach Sean Payton, who was suspended for the entire season. Williams was suspended indefinitely by Goodell. Others who testified included former defensive assistant Mike Cerullo, the initial whistleblower and considered a key NFL witness.

Transcripts portray the former coaching colleagues, all part of the Saints' 2010 Super Bowl championship, as bitterly disagreeing with one another and occasionally contradicting how the NFL depicted the bounty system.

Vitt, Williams and Cerullo appeared separately before Tagliabue and were questioned by lawyers for the NFL and lawyers representing the players originally suspended by Goodell: Jonathan Vilma, Will Smith, Scott Fujita and Anthony Hargrove.

Tagliabue's ruling found that "Saints' coaches and managers led a deliberate, unprecedented and effective effort to obstruct the NFL's investigation. ..."

The transcripts, which could be entered as evidence in Vilma's pending defamation case against Goodell, include numerous testy, and sometimes humorous, exchanges between witnesses and attorneys — and between Tagliabue and the attorneys.

Offering to take a lie detector test, Vitt challenged versions given by Williams and Cerullo. Vitt vowed to sue Cerullo and described Williams as "narcissistic." He referred to both as disgruntled former employees who were fired, even though, publicly, the Saints said Williams' departure for St. Louis was by mutual agreement. Vitt depicted Cerullo as incompetent and said he missed work numerous times and offered bizarre, fabricated excuses for his absences.

Vitt was asked whether he oversaw Cerullo's attempts to destroy evidence related to bounties, which the NFL determined the Saints sanctioned from 2009 to 2011, with thousands of dollars offered for hits that injured opponents and knocked them out of games.

"No. The answer is no," Vitt said. "Cerullo is an idiot."

Williams referred to the case as "somewhat of a witch hunt." He said he wants to coach in the NFL again, "took responsibility so that nobody else had to," and that Vilma has "been made a scapegoat."

Williams stood by his earlier sworn statement that Vilma pledged a $10,000 bounty on quarterback Brett Favre in the Saints' game against the Minnesota Vikings for the NFC championship. But Williams also said that the performance pool he ran was aimed at team bonding, not bounties, and that he saw a difference between asking players to hit hard legally, which he said he did, and asking them to purposely injure an opponent, which he said no one in the organization condoned.

"The game is about a mental toughness on top of a physical toughness," Williams testified at one point. "You know, it's not golf."

Williams, however, acknowledged he suggested Favre should be knocked out of the game.

"We want to play tough, hard-nosed football and look to get ready to play against the next guy. ... Brett is a friend of mine, and so that's just part of this business," Williams said. "You know, at no time, you know, are we looking to try to end anybody's career."

Williams described player pledges to the pool as "nominal" and said they rarely kept the money they earned, either putting it back in the pool or offering it as tips to equipment personnel. In the case of the large amounts pledged during the playoffs, Williams described it as "air" or "funny money" or "banter," adding that he never actually saw any cash collected or distributed and had no idea what would have happened to the money if Cerullo collected it.

Cerullo testified that league investigators misrepresented what he told them, and that, during the playoffs following the 2009 regular season, he kept track of large playoff pledges on note pads but didn't collect the money.

Cerullo said hits for cash started with Williams telling the staff that "Sean kind of put him in charge of bringing back a swagger to the defense ... so he wanted to brainstorm with us as coaches what we thought we could do. ... At one point in one of those meetings, Joe Vitt suggested (his previous teams) had a pay-for-play, pay-for-incentive program that the guys kind of bought into and kind of had fun with, and, you know, that was his suggestion. At that point, Gregg also admitted that other places he was at, they had the same type of thing. And at that point, Gregg kind of ran with it."

Cerullo described pregame meetings during the playoffs, when the Saints faced quarterback Kurt Warner of the Arizona Cardinals and then Favre.

He said Vitt told players Warner "should have been retired" and "we're going to end the career tomorrow of Kurt Warner." Cerullo also quoted Vitt as saying of Favre: "That old man should have retired when I was there. Is he retiring, isn't he retiring — that whole (thing) is over, you know, tomorrow. ... We'll end the career tomorrow. We'll force him to retire. ..."

Cerullo testified that, once word came that the NFL was investigating, Williams told him to delete computer files about bounty amounts and that Vitt checked on his progress.

Asked what motivated him to come forward as a whistleblower with an email to the league in November 2011, Cerullo replied: "I was angry for being let go from the Saints."

Later, he testified: "I was angry at Joe Vitt, and I wanted to show that I was fired for lying and I witnessed Joe Vitt lying and he still had a job. So, that was my goal of reaching out to the NFL."

The transcripts also portray Tagliabue's command of the proceedings, including his efforts to rein in the lawyers.

"I'm going to intervene much more significantly, going forward," Tagliabue interjected at one point, "because I am extremely concerned that this is getting to be cumulative, confusing and useless, and I do not preside over proceedings that are cumulative, confusing and useless."

There also were lighter moments, such as when Tagliabue announced: "I thought I was going to get through this proceeding only by drinking coffee. I'm getting to the point where I need a Bloody Mary."

How “Life of Pi” animators visualized Ang Lee’s blank slate

LOS ANGELES (TheWrap.com) – “Life of Pi” is a movie that has the proverbial cast of thousands… of animals, that is. In one shot set on the ocean, there are 40,000 flying fish. In another one set on a floating island, there are 60,000 meerkats. And not one of them was living and breathing, of course.

“No real meerkats were used,” senior animation supervisor Erik-Jan De Boer told the audience at an effects-themed Q&A following TheWrap’s screening of the movie at the Landmark Theatre on Monday night. “Except of course we went to meerkat sanctuaries and zoos to shoot a lot of reference footage…”

“And the two of us watched every episode of ‘Meerkat Manor,’” interrupted visual effects supervisor Bill Westenhofer. “We were gonna watch one, but it gets addictive.”

That was about all the time these two had to indulge in reality TV during the long gestation and post-production of Pi, which establishes a new benchmark for awe-inspiring digital trickery – particularly in 3D, or “stereo,” as Westenhofer and De Boer refer to the effects-complicating process.

“In total,” De Boer told TheWrap’s editor-in-chief Sharon Waxman, “we animated 580 animals in about 290 shots for the movie, which includes a giraffe, a fox, a fish, and of course the hyena and orangutan.” Not to mention the little matter of the tiger, “Richard Parker,” whose appearances as one of the movie’s co-leads are 15 percent real, 85 percent digital.

That’s not including the aforementioned meerkat and flying fish extras, brought to life via a software program appropriately titled Massive. (If only it had been around in Cecil B. DeMille‘s day.)

“The flying fish sequence is where we start to take some artistic liberties, since Pi’s telling you a tale,” said Westenhofer. “Maybe there were a thousand flying fish in reality, or even a hundred, but you’re seeing his mind’s eye, which saw this multitude, so we have 40,000 in one particular spot. The Massive software is almost artificial intelligence, where you write a little program that’s the brain for each individual fish, and it decides if it’s going to hop out of the water, and how long it’s going to fly; if it sees someone in its path, it does avoidance.”

But before any of that was animated, there was the live-action filming that took place on a 70 meter-by-30 meter wave tank that director Ang Lee had specially built for the film. And there, said Westenhofer, “you had (star) Suraj Sharma on a boat with two guys in rubber rafts just chucking rubber fish at him as hard as they possibly can. It’s a good mixture of the low-tech and the high-tech.”

Of course, it wasn’t fish but previous experience with big cats that got Rhythm & Hues the assignment from Lee to go from lions to tigers and Pi. “He knew we had done the lion in the first Narnia movie. He asked, ‘Does a digital character look more or less real in 3D?’ We looked at each other and thought that was a pretty good question.”

As well as a leading one, since Lee had already made the decision at that point, in 2009, to shoot in 3D. “We took one of the shots and rendered it in stereo and said ‘Yeah, it gives it a little more presence and makes it more real.’” Good answer! “That was the start of our relationship with him.”

Although “Life of Pi” doesn’t exactly go for documentary-style realism, every effort was made to keep the tiger’s actions and reactions to what experts and trainers told them a creature would really do in those situations. Not having him spout any Aslan-style aphorisms was a nice start on that de-anthropomorphizing.

“We always strive for photorealism,” said De Boer – even when they’re working on a Narnia or Cats and Dogs. “Motion-wise we strive for perfect physicality and try to get that animal to behave as characteristically as possible – and then we always have to make them talk or dance or do something really weird, and the realism goes out the window and everybody knows that we were there. For me what was really cool about this movie is not only do we stick with the real animal but we also have to intercut it with a live-action animal, so that made the challenge for us that much bigger.”

Added Westenhofer, “We told the crew we wanted to work ourselves out of any recognition by making it look as real as possible.”

It was at least as big of a challenge, as far as Westenhofer was concerned, to make the digital waves match or amplify the real tank waves – and to create the film’s skies completely from scratch. “There’s not many films where we spend this much time on the water. I think ‘Old Man and the Sea’ harkens back! But even with ‘Titanic,’ you’ll see the water and then go inside.” For much of “Life of Pi,” “inside” amounts to a few furtive peeks under a tarp.

Hence what, on a project like this, becomes a fine line where digital effects providers are also, to some extent, taking over the role of cinematography and art direction. Going to work on filling up these blue-screen shots, the Rhythm & Hues people might well have been humming Bruce Springsteen’s “Empty Sky” to themselves.

“What I’m absolutely most proud of is with these visual effects is that we were given a blank slate for a lot of these shots,” Westenhofer told the audience. “We were given a boat in front of a blue screen, and it was the visual effects team who really were a lot of the creative innovators on the movie. Certainly it was Ang’s vision we were creating. But we’d start a shot, and though Ang absolutely knows what he wants, his communication is sometimes not as specific as you want. Instead of saying ‘I want a three-quarters cloudy sky with yellow over here and some blue,’ he’d say ‘I want a pensive sky.’

Or, ‘I want it to be operatic.’ So it would be our job to go translate that, and the team did a great job of supplying that.

“And Claudio Miranda did an awesome, awesome job on the cinematography, but a lot of the cinematography on the ocean is digital effects.”

Congress examines science behind HGH test for NFL

WASHINGTON (AP) — A congressional committee has opened a hearing to examine the science behind a human growth hormone test the NFL wants to start using on its players.

Nearly two full seasons have passed since the league and the players' union signed a labor deal that set the stage for HGH testing.

The NFL Players Association won't concede the validity of a test that's used by Olympic sports and Major League Baseball, and the sides haven't been able to agree on a scientist to help resolve that impasse.

Among the witnesses before the House Oversight and Government Reform Committee on Wednesday is Pro Football Hall of Fame member Dick Butkus. In his prepared statement, Butkus writes: "Now, let's get on with it. The HGH testing process is proven to be reliable."

Shhhh! A new law says TV ads can't blare anymore

NEW YORK (AP) — TV viewing could soon sound a little calmer. The CALM Act, which limits the volume of TV commercials, goes into effect on Thursday.

CALM stands for Commercial Advertisement Loudness Mitigation. The act is designed to prevent TV commercials from blaring at louder volumes than the program content they accompany. The rules govern broadcasters as well as cable and satellite operators.

The rules are meant to protect viewers from excessively loud commercials.

The Federal Communications Commission adopted the rules a year ago, but gave the industry a one-year grace period to adopt them.

Suspected violations can be reported by the public to the FCC on its website.

Fed adds another $45B per month in stimulus

The Federal Reserve ramped up its stimulus to the economy on Wednesday, expressing disappointment with the pace of recovery in employment as contentious U.S. budget talks heighten uncertainty about the outlook.

The central bank replaced a more modest stimulus program due to expire at year-end with a fresh round of Treasury purchases that will increase its balance sheet. It committed to monthly purchases of $45 billion in Treasuries on top of the $40 billion per month in mortgage-backed bonds it started buying in September.

In a surprise move, the Fed also adopted numerical thresholds for policy, a step that had not been expected until early next year. In particular, the Fed said it will likely keep official rates near zero for as long as unemployment remains above 6.5 percent, inflation between one and two years ahead is projected to be no more than 2.5 percent, and long-term inflation expectations remain contained.

The Fed noted unemployment remains elevated and that inflation is running somewhat below policymakers' 2 percent objective.

"The Committee remains concerned that, without sufficient policy accommodation, economic growth might not be strong enough to generate sustained improvement in labor market conditions," the Fed said in a statement.

Policymakers also repeated a pledge to keep buying bonds until the labor market outlook improves substantially. A drop in the jobless rate to 7.7 percent in November from 7.9 percent in October was driven by workers exiting the labor force, and therefore did not come close to satisfying that condition.

Under the "Operation Twist" program that will expire at the end of the month, the Fed was buying $45 billion in longer-term Treasuries with proceeds from the sale of short-term debt. The new round of government bond-buying it announced on Wednesday will be funded by essentially creating new money, further expanding the Fed's $2.8 trillion balance sheet.

Fed Chairman Ben Bernanke will discuss the central bank's latest decision at a news conference at 2:15 p.m. (1915 GMT).

SWEATING A WEAK RECOVERY

The Fed cut overnight interest rates to near zero in December 2008 and has bought about $2.4 trillion in bonds in a further effort to push borrowing costs lower and spur a stronger recovery.

Despite the unconventional and aggressive efforts, U.S. economic growth remains tepid. GDP grew at a 2.7 percent annual rate in the third quarter, but it now appears to be slowing sharply. According to a Reuters poll published on Wednesday, economists expect the economy to expand at just a 1.2 percent pace in the current quarter.

Businesses have hunkered down, fearful of a tightening of fiscal policy as politicians in Washington wrangle over ways to avoid a $600 billion mix of spending reductions and expiring tax cuts set to take hold at the start of 2013.

Bernanke has warned that running over this "fiscal cliff" would lead the economy into a new recession.

Fed officials will release a new set of quarterly economic and interest rate projections at 2 p.m. (1900 GMT) that could show yet another round of downward revisions to future growth prospects.

Back in September, the Fed predicted the U.S. economy would expand 2.5 percent to 3 percent in 2013, but even that modest rate is looking potentially rosy. The Reuters poll showed a median U.S. growth estimate of 2.1 percent for next year on the same fourth quarter over fourth quarter basis.
