Wall Street ends flat as rally slows, earnings eyed

NEW YORK (Reuters) - Stocks ended little changed on Friday as investors took a step back from buying ahead of next week's busy corporate earnings calendar.

Overall earnings are expected to grow by just 1.9 percent in this season, according to Thomson Reuters data. Analysts say that, with the bar low, there's room for companies to beat expectations, and that may have contributed to the rise in stocks so far in 2013.

That rally has slowed in the last few days.

"It's a market that is waiting for more of a catalyst from earnings," said Quincy Krosby, market strategist at Prudential Financial in Newark, New Jersey.

The S&P 500 index has gained 5 percent over the last two weeks to take the benchmark to five-year highs.

Wells Fargo & Co set a weak tone Friday after it reported results. It showed lower fourth-quarter net interest margin - a key measure of how much money banks make from loans - even as profit jumped.

The bank, which was the first major financial institution to report results this earnings season, also made fewer mortgage loans than in the third quarter.

Wells Fargo ended down 0.8 percent at $35.10, off its lows for the day, while bank shares weighed on the broader market. The S&P 500 financial sector index <.gspf> fell 0.3 percent after rallying more than 1 percent on Thursday.

Bank of America Corp , JPMorgan Chase & Co and Citigroup Inc are due to report results next week, as are other major companies including General Electric and Intel .

An agreement reached in Washington at the start of the year over the "fiscal cliff" saw investors in U.S.-based funds add $7.53 billion to stock mutual funds in the week ended Jan 9, the most since 2001, data from Thomson Reuters' Lipper service showed.

"The money poured into the market at the beginning of the year and you're going to need new money to bring this market higher," said Krosby. She said that in the short-term the market has a bias toward moving higher, even though it is overbought.

The Dow Jones industrial average <.dji> gained 17.21 points, or 0.13 percent, to 13,488.43. The Standard & Poor's 500 Index <.spx> dipped 0.07 points to 1,472.05. The Nasdaq Composite Index <.ixic> added 3.88 points, or 0.12 percent, to 3,125.64.

For the week, the S&P and Dow both gained 0.4 percent and the Nasdaq rose 0.8 percent.

Boeing weighed on the Dow after a cracked cockpit window and an oil leak on separate flights in Japan added to problems with some of its Dreamliner 787 jets, compounding safety concerns about the new aircraft.

The U.S. Department of Transportation said the jet would be subject to a review of its critical systems by regulators. Boeing was the biggest loser on the Dow, falling 2.5 percent to $75.16.

Best Buy rallied after its results showed a small turnaround in U.S. stores, though same-store sales were flat during the key holiday season. Its shares jumped 16.4 percent to $14.21, making it the best performer on the S&P 500.

Dendreon Corp surged 21 percent to $6.17 after Sanford C. Bernstein upgraded the drugmaker's stock to "outperform" from "market-perform" and said it could be one of the best performers in 2013.

Volume was below the 2012 average of 6.42 billion shares traded a day, with roughly 5.93 billion shares changing hands on the New York Stock Exchange, the Nasdaq and the NYSE MKT.

Advancers outpaced decliners on the New York Stock Exchange by 1,578 to 1,393, while advancers narrowly outnumbered decliners on the Nasdaq by 1,228 to 1,223.

Flu Activity Still High: How Long Will it Last?

Most of the country is seeing elevated levels of flu, a trend that may continue for several weeks, according to a new report released today by the Centers for Disease Control and Prevention (CDC).

As of Jan. 5, 47 states were reporting widespread flu activity, meaning more than 50 percent of regions in those states are experiencing flu, the CDC said. That’s up from 41 states the week before. [What You Can Do About the Raging Flu.]

However, flu activity did appear to be declining in some parts of the country, such as the South and Southwest.

Only time will tell whether flu activity in these areas of the country has reached a peak, and will start to decline, or whether visits to the doctor for flu-related symptoms will spike again in the coming weeks. The latest numbers from the CDC are from the last week of December, a time when doctors’ visits might have decreased due to the holiday season, said Dr. Tom Frieden, director of the CDC.

Nationally, the percentage of people visiting the doctor for flulike illness was 4.3 percent, down from 5.6 percent the week before, but above the level of flu activity typically seen during the summer months.

Twenty-four states are reporting high levels of flu activity — down from 29 states the previous week —  and 16 states are reporting moderate levels.

Flu season is unpredictable, so it’s not clear how much longer it will last, but typically, flu activity remains high for 12 weeks before peaking. So far this season, flu activity has remained elevated for five consecutive weeks.

This year’s flu vaccine is moderately effective at protecting against the flu, the CDC said. People who have been vaccinated are 62 percent less likely to visit the doctor for the flu than those who have not been vaccinated, Frieden said. This level of effectiveness is what researchers would expect in a year when the flu strains in the vaccine are closely matched to the strains in circulation.

While the flu vaccine is not perfect, it is the best tool we have to protect against the flu, Frieden said.

Vaccine shortages have been reported in some areas, and people who want to get vaccinated now may have to call or visit several places to find out where the vaccine is available, Frieden said.

Flu vaccination is recommended for everyone ages 6 months and older.

Alabama's Lacy, Milliner, Fluker enter NFL draft

TUSCALOOSA, Ala. (AP) — Alabama tailback Eddie Lacy, cornerback Dee Milliner and right tackle D.J. Fluker are entering the NFL draft after helping lead the Crimson Tide to a second straight national title.

Lacy and Milliner announced their plans to skip their senior seasons Friday at a news conference. Fluker couldn't be there for the announcement because he was traveling.

It's another exodus of talented underclassmen for a team that has won three of the past four national championships. Most of the four first-round picks in each of the past two drafts that left Alabama were underclassmen.

"I appreciate what they've done for the University of Alabama but we also acknowledge the fact that from a business standpoint, these guys are making good decisions about their future and what they can do," coach Nick Saban said.

Unlike recent groups of departing juniors from Alabama, only Milliner is pegged as a sure first-round pick.

He was a Jim Thorpe Award finalist and unanimous All-American after recording two interceptions and 22 pass deflections. He and guard Chance Warmack, who was a senior, are projected as the Tide's top current prospects.

"I think while I was here, I met all the goals and team affirmations that I set for myself as a freshman by winning a championship, becoming an All-American, just being part of a team that always loved to win," Milliner said. "I think I fulfilled all my goals and am ready and prepared to go to the next level."

Lacy was MVP of the national championship game against Notre Dame after rushing for 140 yards and scoring two touchdowns. He said he wasn't 100 percent healthy all season until the title game Monday night, but Lacy still ran for 1,322 yards and 17 touchdowns while averaging 6.5 yards per carry.

"We don't have a lot of years to play this position, so you have to go while you can," Lacy said. "I would love to come back. This is a great place. We have the best fans, but I really didn't want to risk coming back and not having such a good year or maybe even risking injury. I've had my share of injuries this year. I feel like you've got to get out while you can."

Lacy thinks he "made a pretty solid statement" in the title game, when he made a spin move into the end zone on a TD catch and on another run pushed 248-pound linebacker Danny Spond away with one hand.

Lacy was recruited in the same class as Trent Richardson, last year's No. 3 pick by Cleveland, but redshirted and then spent two seasons as a backup. He's not widely projected to follow Richardson and 2009 Heisman Trophy winner Mark Ingram into the first round. Lacy said he was projected as a second- or third-round pick in feedback from the NFL, but was impressive in the finale. Ordinarily, Saban only recommends projected first-round picks leave early.

"I'm fully supportive of what Eddie's doing," Saban said. "It's a little bit of a different situation than we've had in the past, but it's a little bit unique as well. Every one of these situations is unique to that particular individual and what his situation is. "

The 6-foot-6, 335-pound Fluker started 35 games for the Tide and was a second-team Associated Press All-American.

He was one of the Tide's top-rated signees in 2009 but came in overweight at about 395 pounds and was redshirted.

"I certainly feel like this year has been his best year as a player, and I feel that he's made a good decision about what he wants to do," said Saban, adding that Fluker has improved as much as any player on the team.

The mammoth Fluker, who wears a size-22 shoe, said in a statement that leaving early "is never an easy decision when you are playing at a place like Alabama."

"''These four years in Tuscaloosa have been the best four years of my life and I appreciate everyone who helped me along the way," he said.

Quarterback AJ McCarron, All-America linebacker C.J. Moseley and guard Anthony Steen have already said they're returning for their senior seasons. Saban didn't rule out other juniors possibly declaring for the draft before Tuesday's deadline.

The Tide does have promising players who have logged plenty of playing time behind Lacy and Milliner, especially. Two freshmen — tailback T.J. Yeldon (1,108 yards, 12 touchdowns) — and cornerback Geno Smith saw significant action.

"You've got people that are going to go to the NFL each year and you've got people behind them that are going to do the same things when their time comes," Milliner said.

Saudi execution: Brutal and illegal?

STORY HIGHLIGHTS

• Saudi authorities beheaded Rizana Nafeek, a Sri Lankan woman


• She was convicted of killing a baby of the family employing her as a housemaid


• This was despite Nafeek's claims that the baby died in a choking accident


• Becker says her fate "should spotlight the precarious existence of domestic workers"

Jo Becker is the Children's Rights Advocacy Director for Human Rights Watch and author of 'Campaigning for Justice: Human Rights Advocacy in Practice.' Follow Jo Becker on Twitter.

(CNN) -- Rizana Nafeek was a child herself -- 17 years old, according to her birth certificate -- when a four-month-old baby died in her care in Saudi Arabia. She had migrated from Sri Lanka only weeks earlier to be a domestic worker for a Saudi family.

Although Rizana said the baby died in a choking accident, Saudi courts convicted her of murder and sentenced her to death. On Wednesday, the Saudi government carried out the sentence in a gruesome fashion, by beheading Rizana.

Read more: Outrage over beheading of Sri Lankan woman by Saudi Arabia

Rizana's case was rife with problems from the beginning. A recruitment agency in Sri Lanka knew she was legally too young to migrate, but she had falsified papers to say she was 23. After the baby died, Rizana gave a confession that she said was made under duress -- she later retracted it. She had no lawyer to defend her until after she was sentenced to death and no competent interpreter during her trial. Her sentence violated international law, which prohibits the death penalty for crimes committed before age 18.

Rizana's fate should arouse international outrage. But it should also spotlight the precarious existence of other domestic workers. At least 1.5 million work in Saudi Arabia alone and more than 50 million -- mainly women and girls -- are employed worldwide according to the International Labour Organization (ILO).

Again according to the ILO, the number of domestic workers worldwide has grown by more than 50% since the mid-1990s. Many, like Rizana, seek employment in foreign countries where they may be unfamiliar with the language and legal system and have few rights.

When Rizana traveled to Saudi Arabia, for example, she may not have known that many Saudi employers confiscate domestic workers' passports and confine them inside their home, cutting them off from the outside world and sources of help.

It is unlikely that anyone ever told her about Saudi Arabia's flawed criminal justice system or that while many domestic workers find kind employers who treat them well, others are forced to work for months or even years without pay and subjected to physical or sexual abuse.

Conditions for migrant domestic workers in Saudi Arabia are among some of the worst, but domestic workers in other countries rarely enjoy the same rights as other workers. In a new report this week, the International Labour Organization says that nearly 30% of the world's domestic workers are completely excluded from national labor laws. They typically earn only 40% of the average wage of other workers. Forty-five percent aren't even entitled by law to a weekly day off.

Last year, I interviewed young girls in Morocco who worked 12 hours a day, 7 days a week for a fraction of the minimum wage. One girl began working at age 12 and told me: "I don't mind working, but to be beaten and not to have enough food, this is the hardest part."

Many governments have finally begun to recognize the risks and exploitation domestic workers face. During 2012, dozens of countries took action to strengthen protections for domestic workers. Thailand, and Singapore approved measures to give domestic workers a weekly day off, while Venezuela and the Philippines adopted broad laws for domestic workers ensuring a minimum wage, paid holidays, and limits to their working hours. Brazil is amending its constitution to state that domestic workers have all the same rights as other workers. Bahrain codified access to mediation of labor disputes.

Perhaps most significantly, eight countries acted in 2012 to ratify -- and therefore be legally bound by -- the Domestic Workers Convention, with more poised to follow suit this year. The convention is a groundbreaking treaty adopted in 2011 to guarantee domestic workers the same protections available to other workers, including weekly days off, effective complaints procedures and protection from violence.

The Convention also has specific protections for domestic workers under the age of 18 and provisions for regulating and monitoring recruitment agencies. All governments should ratify the convention.

Many reforms are needed to prevent another tragic case like that of Rizana Nafeek. The obvious one is for Saudi Arabia to stop its use of the death penalty and end its outlier status as one of only three countries worldwide to execute people for crimes committed while a child.

Labor reforms are also critically important. They may have prevented the recruitment of a 17 year old for migration abroad in the first place. And they can protect millions of other domestic workers who labor with precariously few guarantees for their safety and rights.

Ald. Sandi Jackson resigns from Chicago City Council

Ald. Sandi Jackson has resigned from the Chicago City Council.

The 7th Ward alderman submitted her resignation letter to Mayor Rahm Emanuel today. It is effective Tuesday.

"After much consideration and while dealing with very painful family health matters, I have met with my family and determined that the constituents of the 7th Ward, as well as you Mr. Mayor, and my colleagues in the City Council deserve a partner who can commit all of their energies to the business of the people. Therefore, it is with a heavy heart that I tender my resignation as Alderman of 7th Ward, effective January 15, 2013," reads the letter released by the mayor's office.

Ald. Jackson's resignation comes after her husband, Jesse Jackson Jr., resigned from Congress before Thanksgiving amid federal ethics probes and a diagnois of bipolar depression.

Talk swirled around City Hall that Ald. Jackson also would step down, but she remained on the council until Friday afternoon.

Emanuel put out a statement about the resignation.

"As Sandi takes this time to focus on her family, we give her our deepest thanks and support for her service to our City and the residents of her ward.  Her leadership has been greatly appreciated in the Chicago City Council," the statement read.

"The process to identify a replacement for Alderman Jackson to serve and represent the residents of Chicago’s 7th ward will be announced early next week."

A month ago, amid rumors that she was considering a run to replace her husband in Congress, Jackson denied she was interested in the job and said she wouldn’t resign from the City Council unless "something catastrophic happens.”
 
At the same time, she also said she was undecided about whether to move back to Chicago from Washington, D.C., where the couple lives with their children.

"I will finish my term. I intend to finish my term," Ald. Jackson said then. "Unless something catastrophic happens -- I could step outside and get hit by a bus today."

Her husband, in his resignation letter to House Speaker John Boehner in November, appeared to try to shield his wife in the federal ethics investigation. "I am doing my best to address the situation responsibly, cooperate with the investigators, and accept responsibility for my mistakes, for they are my mistakes and mine alone," the former congressman wrote. "None of us is immune from our share of shortcomings or human frailties, and I pray that I will be remembered for what I did right."
 
The former congressman paid his wife hundreds of thousands of dollars in campaign funds to act as his political consultant.

Obama, Karzai agree to speed up Afghan military transition

WASHINGTON (Reuters) - President Barack Obama and Afghan President Hamid Karzai agreed on Friday to speed up the handover of combat operations in Afghanistan to Afghan forces this year, underscoring Obama's determination to move decisively to wind down the long, unpopular war.

Signaling a narrowing of differences, Karzai appeared to give ground in White House talks on U.S. demands for immunity from prosecution for any U.S. troops who stay in Afghanistan beyond 2014, a concession that could allow Obama to keep at least a small residual force there.

Both leaders also threw their support behind tentative Afghan reconciliation efforts with Taliban insurgents. They each voiced support for the establishment of a Taliban political office in the Gulf state of Qatar in hopes of bringing insurgents to inter-Afghan talks.

Karzai's visit, which follows a year of growing strains in U.S.-Afghan ties, comes amid stepped-up deliberations in Washington over the size and scope of the U.S. military role in Afghanistan once the NATO-led combat mission concludes at the end of next year.

The Obama administration has been considering a residual force of between 3,000 and 9,000 troops in Afghanistan to conduct counterterrorism operations while providing training and assistance for Afghan forces.

But a top Obama aide said this week that the administration does not rule out a complete withdrawal after 2014, a move that some experts say would be disastrous for the still-fragile Afghan government and its fledgling security apparatus.

Saying that Afghan forces were being trained and were "stepping up" faster than expected, Obama said Afghan troops would take over the lead in combat missions across the country this spring, rather than waiting until the summer, as was originally planned.

"Starting this spring, our troops will have a different mission: training, advising, assisting Afghan forces," Obama said. "It will be a historic moment and another step toward full Afghan sovereignty."

There are some 66,000 U.S. troops currently in Afghanistan. NATO allies have also been steadily reducing their troop numbers there with the aim of ending the foreign combat role in 2014, despite doubts about the ability of Afghan forces to shoulder full responsibility for security.

Obama said final decisions on this year's troop reductions and the post-2014 U.S. military role were still months away, but his comments raised the prospects of an accelerated withdrawal timetable as the security transition proceeds.

Precisely how much of an acceleration was unclear.

For his part, Karzai voiced satisfaction over Obama's agreement to turn over control of detention centers to Afghan authorities, a source of dispute between their countries.

The two leaders, who have had a tense relationship in the past, stood side by side in the White House East Room, nodding occasionally as the other spoke.

Obama once called Afghanistan a "war of necessity," but he is heading into a second term looking for an orderly way out of the conflict, which was sparked by the September 11, 2001 attacks by al Qaeda on the United States.

Wall Street climbs as China data puts S&P back at five-year high

NEW YORK (Reuters) - Stocks rose on Thursday and the S&P 500 ended at a fresh five-year high as stronger-than-expected exports from China spurred optimism about global growth prospects.

Buying accelerated late in the day after the S&P 500 broke through technical resistance at 1,466.47, which was the market's closing level last Friday and the highest level since December 2007.

"Historically, January is a positive month for the market and you're seeing that play out," said Michael Sheldon, chief market strategist at RDM Financial in Westport, Connecticut.

Financial and energy stocks were the day's top gainers. The financial sector index <.gspf> rose 1.4 percent and the energy sector <.gspe> was up 1 percent.

Analysts cited economic data out of China as the day's catalyst, which showed the country's export growth rebounded sharply to a seven-month high in December, a strong finish to the year after seven straight quarters of slowdown.

"It is being interpreted positively that they've stopped the downturn (in growth)," said Kurt Brunner, portfolio manager at Swarthmore Group in Philadelphia.

"If they continue to produce good growth, that's going to be supportive of our global manufacturers."

Wall Street's fear gauge, the CBOE Volatility Index <.vix> suggested markets were relatively calm. The VIX was down 2.3 percent at 13.49.

At Thursday's close, the S&P sits about 6 percent below its all-time closing high of 1,565.15, hit in October 2007.

The Dow Jones industrial average <.dji> gained 80.71 points, or 0.60 percent, to 13,471.22. The Standard & Poor's 500 Index <.spx> rose 11.10 points, or 0.76 percent, to 1,472.12. The Nasdaq Composite Index <.ixic> added 15.95 points, or 0.51 percent, to 3,121.76.

Thursday's session had earlier included a dip that traders said was triggered by a trade in the options market that prompted a large amount of S&P futures to hit the market at the same time. That sent the S&P 500 index down rapidly but those losses were reversed through the afternoon.

Financials benefited from events this week that added clarity to mortgage rules and banks' potential exposure to the housing market.

The U.S. government's consumer finance watchdog announced mortgage rules on Thursday that will force banks to use new criteria to determine whether a borrower can repay a home loan.

Earlier this week, several big mortgage lenders reached a deal with regulators to end a review of foreclosures mandated by the government.

"It's a resolution. It's not hanging over their heads," said Brunner.

Bank of America gained 3.1 percent to $11.78, while Morgan Stanley was up 3.7 percent at $20.34, one day after sources said the bank plans to cut jobs.

Shares of upscale jeweler Tiffany dropped 4.5 percent to $60.40 after it said sales were flat during the holidays.

Herbalife Ltd stepped up its defense against activist investor Bill Ackman, stressing it was a legitimate company with a mission to improve nutrition and help public health. The stock ended down 1.8 percent at $39.24 after a volatile day.

After the closing bell, American Express said it would cut about 5,400 jobs, and take about $600 million in after-tax charges in the fourth quarter. The stock added 0.7 percent to $61.20 in after-hours trade.

Volume was above the 2012 average of 6.42 billion shares traded a day, with roughly 6.77 billion shares changing hands on the New York Stock Exchange, the Nasdaq and the NYSE MKT.

Advancers outnumbered decliners on the NYSE by 1,916 to 1,039, while advancers also outpaced decliners on the Nasdaq by 1,439 to 1,036.

What Will It Take to Solve Climate Change?

Australia had to add a new color to its weather maps this week. Meteorologists used royal purple to denote an off-the-charts high temperature of 50 degrees Celsius (122 degrees Fahrenheit), part of an unprecedented heat wave and ongoing wildfires occurring down under this month. On the other side of the globe, 2012 proved the hottest year on record in the contiguous U.S., surpassing the previous record-holder by a full degree F (0.6 deg C). In short, global warming is continuing to turn up the heat–so what are we going to do about it?The goal is simple: reduce greenhouse gas emissions to restrain future warming or even begin to draw down carbon dioxide concentrations in the atmosphere. But the challenge of achieving that goal is large–greenhouse gas emissions are intimately related to fossil fuel combustion, which is the motor of the global economy.One idea to begin to solve this problem, mooted in 2004 by Princeton University mechanical engineer Robert Socolow and ecologist Stephen Pacala, was to identify what the scientists dubbed ” wedges”–one billion metric ton reductions in carbon emissions that could be maintained for the next 50 years. So, for example, stopping any further increase in greenhouse gas emissions could be done by employing several of these wedges, such as doubling vehicle fuel efficiency or replacing coal-fired power plants with nuclear ones. Employ enough of these wedges–seven in the estimation of Socolow and Pacala–and the problem of climate change begins to dissipate. And the researchers offered 15 potential wedges–ranging from carbon capture and storage to ending deforestation–to achieve the goal. As the co-authors put it in the paper presenting the idea published in Science: “Humanity already possesses the fundamental scientific, technical, and industrial know-how to solve the carbon and climate problem.”Great! The only problem is: if we do indeed possess the know-how, we have yet to employ it. Eight years later, global greenhouse gas emissions continue to grow faster than ever. We have lost time, and that time will cost us, both in terms of the cost of combating climate change and the ultimate impacts.According to a new analysis published online in Environmental Research Letters on January 9, the world now likely needs 12 wedges just to get back to the business-as-usual scenario outlined by Socolow and Pacala in 2004. Add another nine billion ton wedges if you want to stabilize emissions at last year’s levels, and add another 10 if you’d like to keep greenhouse gas concentrations from rising above 500 parts-per-million. Already, concentrations are at 394 ppm, up from 280 ppm before the dawn of widespread fossil fuel burning. That’s if you also want the global economy to continue to grow at the same time.Such global growth may be vital as societies strive to bring modern energy to the 2 billion or so people still reliant on wood, dung and kerosene for their cooking and lighting needs. Even more challenging, the key to reducing emissions is reducing the burning of fossil fuels, or at least the impacts of that burning–and all the technologies needed to do that are stalled (CCS), slow-moving (nuclear) or immature (renewables). The world will need to deploy “tens of terawatts of carbon-free energy in the next few decades,” as the researchers write in Environmental Research Letters.What such a “transformation” would mean specifically remains entirely undiscussed in the analysis, as Socolow notes in a written critique of the paper shared this week with journalists. Regardless, that kind of energy revolution certainly seems challenging, which is why some have begun to wonder whether it’s time to at least explore technologies that might reduce the worst of global warming, collectively known as geoengineering, such as fertilizing the ocean with iron or artificial volcanoes. Of course, such solutions present their own challenges like: who controls the planetary thermostat? “The stricter the [climate] goal, the greater the risk of recklessness,” such as ill-considered geoengineering schemes, warns Socolow.Or, as earth system scientist Stephen Davis of the University of California, Irvine, and lead author of the wedges reanalysis argues: “The only real solution to climate change is to stop dumping CO2 into the atmosphere altogether.” If we want to begin to restrain global warming, we better get started–and soon.

Researchers: NFL's Seau had from brain disease

When he ended his life last year by shooting himself in the chest, Junior Seau had a degenerative brain disease often linked with repeated blows to the head.

Researchers from the National Institutes of Health said Thursday the former NFL star's abnormalities are consistent with chronic traumatic encephalopathy, or CTE.

The hard-hitting linebacker played for 20 NFL seasons with San Diego, Miami and New England before retiring in 2009. He died at age 43 of a self-inflicted gunshot in May, and his family requested the analysis of his brain.

"We saw changes in his behavior and things that didn't add up with him," his ex-wife, Gina, told The Associated Press. "But (CTE) was not something we considered or even were aware of. But pretty immediately (after the suicide) doctors were trying to get their hands on Junior's brain to examine it."

The NIH, based in Bethesda, Md., studied three unidentified brains, one of which was Seau's, and said the findings on Seau were similar to autopsies of people "with exposure to repetitive head injuries."

"It was important to us to get to the bottom of this, the truth," Gina Seau added, "and now that it has been conclusively determined from every expert that he had obviously had CTE, we just hope it is taken more seriously. You can't deny it exists, and it is hard to deny there is a link between head trauma and CTE. There's such strong evidence correlating head trauma and collisions and CTE."

In the final years of his life, Seau had wild behavioral swings, according to Gina and to 23-year-old son, Tyler, along with signs of irrationality, forgetfulness, insomnia and depression.

"He emotionally detached himself and would kind of 'go away' for a little bit," Tyler Seau said. "And then the depression and things like that. It started to progressively get worse."

He hid it well in public, they said, but not when he was with family or close friends.

Seau joins a list of several dozen football players who were found to have CTE. Boston University's center for study of the disease reported last month that 34 former pro players and nine who played only college football suffered from CTE.

The NFL faces lawsuits by thousands of former players who say the league withheld information on the harmful effects of concussions. According to an AP review of 175 lawsuits, 3,818 players have sued. At least 26 Hall of Famer members are among the players who have done so.

The National Football League, in an email to the AP, said: "We appreciate the Seau family's cooperation with the National Institutes of Health. The finding underscores the recognized need for additional research to accelerate a fuller understanding of CTE.

"The NFL, both directly and in partnership with the NIH, Centers for Disease Control and other leading organizations, is committed to supporting a wide range of independent medical and scientific research that will both address CTE and promote the long-term health and safety of athletes at all levels."

NFL teams have given a $30 million research grant to the NIH.

The players' union called the NIH report on Seau "tragic."

"The only way we can improve the safety of players, restore the confidence of our fans and secure the future of our game is to insist on the same quality of medical care, informed consent and ethical standards that we expect for ourselves and for our family members," the NFLPA said in a statement.

"This is why the players have asked for things like independent sideline concussion experts, the certification and credentialing of all professional football medical staff and a fairer workers compensation system in professional football," it said.

Seau is not the first former NFL player who killed himself and later was found to have had CTE. Dave Duerson and Ray Easterling are the others.

Before shooting himself, Duerson, a former Chicago Bears defensive back, left a note asking that his brain be studied for signs of trauma. His family filed a wrongful-death suit against the NFL, claiming the league didn't do enough to prevent or treat the concussions that severely damaged his brain.

Easterling played safety for the Falcons in the 1970s. After his career, he suffered from dementia, depression and insomnia, according to his wife, Mary Ann. He committed suicide last April.

Mary Ann Easterling is among the plaintiffs who have sued the NFL.

Tyler Seau played football through high school and for two years in college. He says he has no symptoms of brain trauma.

"I was not surprised after learning a little about CTE that he had it," Tyler said. "He did play so many years at that level. I was more just kind of angry I didn't do something more and have the awareness to help him more, and now it is too late."

Gina Seau's son Jake, now a high school junior, played football for two seasons but has switched to lacrosse and has been recruited to play at Duke.

"Lacrosse is really his sport and what he is passionate about," she said. "He is a good football player and probably could continue. But especially now watching what his dad went through, he says, 'Why would I risk lacrosse for football?'

"I didn't have to have a discussion with him after we saw what Junior went through."

Her 12-year-old son Hunter has shown no interest in playing football.

"That's fine with me," she said.

'Lincoln' leads Academy Award contenders with 12 nominations

With a conspicuous diss of Kathryn Bigelow, the un-nominated director of “Zero Dark Thirty,” the Academy Awards nominations were announced Thursday morning.

“Zero Dark Thirty” was one of nine films given the best picture nomination nod. The others: “Beasts of the Southern Wild”; “Silver Linings Playbook”; “Lincoln”; “Les Miserables”; “Life of Pi”; “Amour”; “Django Unchained”; and “Argo.” With 12 nominations total, director Steven Spielberg’s “Lincoln” led this year’s pack, unusually full of films that have reached a broad mainstream audience. “Life of Pi” came in with 11 nominations; “Silver Linings Playbook” and “Les Miserables” received eight.

The best actress Oscar nominees include the oldest-ever performer in that category (Emmanuelle Riva, 85, for “Amour”) as well as the youngest (Quvenzhane Wallis, 9, “Beasts of the Southern Wild”). They’ll compete for the Feb. 24 Oscars against Naomi Watts (“The Impossible”), Jessica Chastain (“Zero Dark Thirty”) and Jennifer Lawrence (“Silver Linings Playbook”).

To the surprise of no one on this planet or any other, Daniel Day-Lewis led the best actor competition for “Lincoln.” His fellow nominees: Denzel Washington, “Flight”; Hugh Jackman, “Les Miserables”; Bradley Cooper, “Silver Linings Playbook”; and in the year’s most unsettling performance, Joaquin Phoenix, “The Master.”

“Silver Linings Playbook” fared well, against some predictions, scoring a supporting actor nomination for Robert De Niro and a supporting actress nod for Jacki Weaver. Other supporting actors nominated include Christoph Waltz for “Django Unchained”; Philip Seymour Hoffman, “The Master”; Alan Arkin, “Argo”; and Tommy Lee Jones,” Lincoln.” All have won Oscars before.

Along with Weaver, Sally Field received a supporting actress nomination, hers for “Lincoln.” The competition: Anne Hathaway, singing her guts out all the way to the podium on Feb. 24 (I’m guessing) for “Les Miserables”; Helen Hunt for “The Sessions” (more of a leading role, in fact); and Amy Adams as the Lady Macbeth of the action in “The Master.”

It’s a huge showing for “Beasts of the Southern Wild,” whose director, Benh Zeitlin, goes toe to toe against his fellow directing nominees David O. Russell (“Silver Linings Playbook”), Ang Lee (“Life of Pi”), Michael Haneke (“Amour”) and Spielberg. Along with “Zero Dark Thirty” director Bigelow, “Argo” helmer Ben Affleck, widely expected to be nominated ... wasn’t.
