Tens of thousands in Spain protest economic policy, corruption

MADRID (Reuters) - Tens of thousands of Spaniards marched through cities across the country on Saturday to protest deep austerity, the privatization of public services and political corruption.

Gathering under the banner of the "Citizen Tide", students, doctors, unionists, young families and pensioners staged rowdy but non-violent demonstrations as a near five-year economic slump shows no sign of recovery and mass unemployment rises.

"I'm here to add my voice. They're cutting where they shouldn't cut; health, education ... basic services. And the latest corruption scandal is just the tiniest tip of a very large iceberg," said Alberto, 51, an account administrator for a German multinational in Madrid, who preferred not to give his surname.

Protests in Spain have become commonplace as the conservative government passes measures aimed at shrinking one of the euro zone's highest budget deficits and reinventing an economy hobbled by a burst housing bubble.

Prime Minister Mariano Rajoy has introduced some of the deepest budget cuts in Spain's democratic history in an attempt to convince investors the country can weather the economic crisis without falling back on international aid.

But, with more than half of the country's young people out of work and growth not expected until sometime next year, the measures have only scratched the surface of the budget shortfall which is expected to be more than double the target in 2014.

Meanwhile, corruption scandals which have hit the ruling party as well as the once-popular royal family has left many Spaniards disenchanted with their leaders on all sides of the political spectrum.

In Madrid, under a clear, cold winter sky, Saturday's marches convened from four different points by early evening in Neptune Square, between the heavily policed and barricaded parliament, the Ritz Hotel and the stock exchange.

Carrying placards which condemned everything from cuts in the health sector to massive bailouts granted to Spain's banking system, crowds banged drums and chanted, while dozens of riot police stood on the sidelines.

The march coincided with the anniversary of a failed coup attempt in 1981 by Civil Guard officers who stormed Parliament and held deputies hostage until the next day.

Paying People to Play Video Games

House Speaker John Boehner tweets that the Obama administration is spending $ 1.2 million “paying people to play video games.” That’s misleading. The government did pay $ 1.2 million for university research that includes the study of how video games can stimulate the cognitive abilities of seniors. A fraction of that cost went to compensate seniors who participated in the study, researchers say.

Boehner was one of several prominent Republican congressmen who sent out a flurry of tweets – hashtag #cutwaste – distorting the research. Some Republicans said the money was spent to play the video game World of Warcraft. That’s wrong. World of Warcraft is not part of research funded by the federal government, although the study does use, in part, the Wii game Boom Blox.

We take no position on whether spending $ 1.2 million studying ways to improve the cognitive abilities of seniors is a waste of taxpayer money. But the Republicans should call it what it is and not distort the facts – even if they get only 140 characters to make their case against it.

But before we get into the facts of the research project, let’s dissect the anatomy of this Republican talking point.

The first volley in the “World of Warcraft” Twitter campaign appears to have come from House Majority Leader Eric Cantor on Feb. 19.

Cantor, Feb. 19: President Obama wants to raise your taxes so he can pay people $ 1.2 million to play World of Warcraft. http://1.usa.gov/Y3NGOH

The link goes to a press release from Cantor’s office listing a number of examples of “federal government waste,” including: “The National Science Foundation spent $ 1.2 million paying seniors to play ‘World of Warcraft’ to study the impact it had on their brain.” That’s not exactly right, but even that incomplete description gets further distorted in a series of tweets from Cantor and other House Republicans on Feb. 20.

Cantor, 10:56 a.m.: Federal Government spends $ 1.2 million paying people to play World of Warcraft video games. Instead of raising taxes, let’s #CutWaste

Speaker John Boehner, 10:57 a.m.: Pres Obama wants more tax hikes, refuses to #cutwaste like $ 1.2M spent paying people to play video games #Obamaquester

GOP Whip Rep. Kevin McCarthy, 11:01 a.m.: Not a kid’s fairytale: fed gov’t actually pays ppl w taxpayer dollars to play video games. Time to #CutWaste. http://1.usa.gov/Y3NH4U

Rep. Ann Wagner, 11:01 a.m.: Did you know the govt paid $ 1.2 million to pay people to play World of Warcraft? http://tinyurl.com/bg8njug Instead of tax hikes #CutWaste

Rep. Diane Black, 11:03 a.m.: Waste of the Day: $ 1.2 million tax dollars used to pay people to play World of Warcraft http://bit.ly/UIG5oK #CutWaste don’t raise taxes

Rep. Renee Ellmers, 11:08 a.m.: Tax dollars at work: govt paid $ 1.2 million to study seniors playing World of Warcraft http://tinyurl.com/bg8njug Instead of tax hikes #CutWaste

Rep. Darrell Issa, 11:46 a.m.: That awkward moment when @BarackObama says “We don’t have a spending problem” then it comes out the Gov paid $ 1.2 mil to play video games…

Rep. David McKinkley, 12:15 p.m.: Did you know the govt paid $ 1.2 million to pay people to play World of Warcraft? http://tinyurl.com/bg8njug Instead of tax hikes #CutWaste

How did this research grant suddenly become the poster child for government waste? It traces its roots to “Wastebook 2012,” Sen. Tom Coburn’s list of 100 wasteful government expenditures. The project in question was No. 87.

Coburn, Wastebook 2012: 87) Should grandparents play World of Warcraft ? — (NC) $ 1.2 million

Soon, grandma may have to skip dinner to join her World of Warcraft guild in a dungeon raid. Researchers believe they have found another means to help our memories as we age: the “World of Warcraft,” a fantasy video game featuring characters like orcs, trolls, and warlocks. The team of academics used part of $ 1.2 million in grants from the National Science Foundation to continue a video game study this year.

The study asked 39 adults ages 60 to 77 to play “World of Warcraft” for two hours a day over two weeks. In the game, players choose a character and rove around the virtual world participating in guild (group) missions, casting spells, and defeating evil creatures.

Millions of people around the world play, with the average player spending almost 11 hours per week playing.

At the end of the two-week study period, researchers found no cognitive improvement in older people who already scored well on cognitive tests. People who started out with lower initial results, however, experienced some improvements.

It’s true that the National Science Foundation — using funds from the economic stimulus — funded two grants totaling $ 1.2 million to study the ways in which the use of some video games by older people can improve their cognitive and everyday abilities, such as memory and reasoning. You can read the abstracts for the two grant awards here and here.

More broadly, according to the abstract, the researchers hope to “advance the knowledge and understanding of how cognitive training reduces age-related decline.”

The project is being led by Anne McLaughlin and Jason Allaire, both at the North Carolina State University’s Gains Through Gaming Lab, which is “dedicated to conducting applied research examining the relationship between playing commercially available video games and important psychological constructs” and specifically “how video games can improve cognitive functioning.”

We spoke to McLaughlin about the way her research was being characterized by Republican leaders in the House.

“Misleading doesn’t describe it,” McLaughlin said. “It is entirely inaccurate.”

For starters, she said, the research that included the World of Warcraft game was not funded by the National Science Foundation, though it helped to set the stage for the federally funded project.

The initial study looked at the effects of playing an “attentionally demanding game” — in this case, World of Warcraft — on the cognitive abilities of seniors. For the uninitiated, World of Warcraft is a massively multiplayer online role playing game (MMORPG). (It’s the game featured in episodes of “South Park” and the sitcom “Big Bang Theory.”)

The study cost a total of $ 5,000 and was funded entirely by N.C. State, McLaughlin said. It was initiated as a pilot and showed some promising results in improving the cognitive abilities of some seniors, particularly those who scored poorly in the cognitive pre-tests. Results of this study were featured in stories by the Los Angeles Times, Time magazine and CBS News, as well as in a press release from N.C. State.

Spurred by those results, McLaughlin and Allaire sought and were awarded two grants from the NSF to perform a much larger series of studies — in part employing the interactive Wii game Boom Blox.

By manipulating various aspects of the game, they are trying to pinpoint what kinds of game play best improve cognition and functioning for older adults, McLaughlin said, as well as determining the effects of playing alone versus in groups.

That’s just the first phase. Then, in collaboration with computer whizzes at Georgia Tech, they hope to develop guidelines for games for older players that will lead to “a new class of ‘brain games’ with reliable effectiveness,” according to the abstract.

“The whole purpose of this is to generalize beyond any game and promote cognitive improvement,” McLaughlin said.

Begun in 2009, the research is still in progress, McLaughlin said.

For the record, McLaughlin said, “We don’t pay anyone to play video games. We pay them to participate in a study.”

Participants first take a three-hour cognitive test to use as a baseline. Then they are asked to come back and play a video game for an hour a day for 15 straight days. Then they are given another three-hour cognitive test immediately afterward, and then two more tests — one three months later and the last a year later. The amount of the $ 1.2 million grant money spent on paying the participants of the study is a small fraction of the overall cost, McLaughlin said.

We initially were led to the grants after making an inquiry with Cantor’s office seeking backup material for claims about the federal government spending $ 1.2 million for people to play World of Warcraft.

In addition to passing along links to the study abstracts, Megan Whittemore, Cantor’s press secretary, offered this response: “The President of the United States said he was going to have to turn criminals loose on the street. Clearly, he created a false choice between raising taxes or near-apocalyptic conditions. In reality, we need to make choices on how the federal government spends taxpayers’ hard earned dollars. While some of these programs may have some merit to some people, should they be saved before preventing the drastic scenario the President painted this week?”

Again, as independent fact-checkers, we take no position about whether these grants are a worthwhile use of taxpayer money. Cutting budget deficits — a stated goal of both Republicans and Democrats — is going to require some tough choices. But the facts simply get in the way of this Republican talking point. Paying people $ 1.2 million to play video games sounds a lot more outrageous than studying ways to improve the cognitive abilities of seniors. And it misleadingly twists what the grants are all about.

Sean Lowe Reveals His Feelings as The Bachelor Winds Up

TV Watch
People Exclusive

By Carrie Bell

02/23/2013 at 05:30 PM EST

As another Bachelor journey races to a dramatic finish, PEOPLE figured it was time to check in with Sean Lowe to get his exclusive thoughts on the recently eliminated, the final three, the all-important overnight dates in Thailand – and the accompanying sex speculation, Tierra's engagement and the Women Tell All reunion.

After pegging Des as "the one," her dismissal still comes as a shock.
Des had the second one-on-one of the season, and I thought after that date that she would most likely be the one. From the very beginning, we got along so well. … But as the season progressed, she started to doubt our relationship a little bit, and that was cause for concern. I felt like Des had a tendency to hide things behind her smile and, after hearing about her childhood … I think a lot of times she probably had to put on a brave face when she probably just wanted to let go and be emotional.

Choosing to send someone home is also having to decide to keep others. Why did you choose the final three?
I can go down the line. Lindsay was sweet, supportive, an incredible girl, and we get along so well together. She was someone I could picture marrying. AshLee has everything I'm looking for. Despite everything she went through as a child, she came out this strong, confidant woman. She truly has a heart where she just wants to love a man, and I can tell she will be a wonderful mother. And Catharine fits the best friend mold. … We have fun together, can be passionate at times and she's also very intellectual, which is an attractive quality to me.

Catherine's family seemed to be discreetly warning you that she might not be ready for marriage and kids right now, like you seem to be.
Let me clarify. I'm not in a hurry to be a dad. I'm looking forward to that next chapter because I've been a single guy for so long. But kids can wait for a while as we get to know each other. I do want someone who shares the same vision of the future as I do. That's a no-brainer.

Did her family's comments seem to contradict that plan?
It was cause for concern. Her sisters made comments like she wants to pursue her career in New York. I'm all for that, but I thought it was odd that she didn't bring that to me herself.

So, after hometowns came the overnights and fantasy suites. How did you feel when you were about to have those dates?
Going into the overnight dates in Thailand, I was stressed out because I had no idea how the three remaining women stacked up. I didn't have them ranked 1,2,3. It was like splitting thirds, because I was falling for all of them for different reasons. They are all wonderful girls with their own unique and special qualities. … At the end of the week, I had to make a decision And ultimately I would end up breaking one of their hearts.

Did you learn something on the overnight dates that made it clear to you who to send home?
No. I was hoping that might be the case, and I wish it had been, but it wasn't.

AshLee proclaimed her love for you early. Did that spook you?
No, not really. I know Ashley is a passionate person, and that translates into being very emotional. She admitted early on that she has a hard time trusting guys because she has abandonment issues. So she let me take control, and … it was comforting to know that we'd already reached that level.

Is the drama over?
There is so much more drama left. I wouldn't consider myself a very emotional person. Outside of Ashley telling me the story of meeting her father for the first time, I couldn't tell you the last time I cried before that. But before the next episode's rose ceremony, I remember putting my suit on, getting ready to face the day and I broke down. I realized the magnitude of the day. It hit me all at once.

Are you looking forward to the reunion special and facing all your castoffs?
For the most part, I am anxious and eager to see the girls. I have such great memories of all of them.

What is your final take on Tierra and all the hate flowing her direction?
I do feel bad for Tierra. She is clearly not an evil person. She was always sweet around me. Granted, she handled herself so poorly and was completely different around the women. She shouldn't have done this show. If you can't get along with your peers, this is going to be hell for you. But she doesn't deserve a lot of the stuff I've read being said about her. It's just hateful. Although her eyebrows are getting some love. Their blog has like 25,000 followers.

And she's now engaged.
So I heard.

How does it feel that speculation over what happened behind closed doors on the overnights is a huge topic of conversation?
It's annoying and tiring. I don't like dealing with those headlines and that gossip because frankly it's none of their business. And two, out of all things you can focus on, there's so much more to talk about.

Well, maybe people like to picture you naked.
I don't know why.

FDA approves new targeted breast cancer drug

WASHINGTON (AP) — The Food and Drug Administration has approved a first-of-a-kind breast cancer medication that targets tumor cells while sparing healthy ones.

The drug Kadcyla from Roche combines the established drug Herceptin with a powerful chemotherapy drug and a third chemical linking the medicines together. The chemical keeps the cocktail intact until it binds to a cancer cell, delivering a potent dose of anti-tumor poison.

Cancer researchers say the drug is an important step forward because it delivers more medication while reducing the unpleasant side effects of chemotherapy.

"This antibody goes seeking out the tumor cells, gets internalized and then explodes them from within. So it's very kind and gentle on the patients — there's no hair loss, no nausea, no vomiting," said Dr. Melody Cobleigh of Rush University Medical Center. "It's a revolutionary way of treating cancer."

Cobleigh helped conduct the key studies of the drug at the Chicago facility.

The FDA approved the new treatment for about 20 percent of breast cancer patients with a form of the disease that is typically more aggressive and less responsive to hormone therapy. These patients have tumors that overproduce a protein known as HER-2. Breast cancer is the second most deadly form of cancer in U.S. women, and is expected to kill more than 39,000 Americans this year, according to the National Cancer Institute.

The approval will help Roche's Genentech unit build on the blockbuster success of Herceptin, which has long dominated the breast cancer marketplace. The drug had sales of roughly $6 billion last year.

Genentech said Friday that Kadcyla will cost $9,800 per month, compared to $4,500 per month for regular Herceptin. The company estimates a full course of Kadcyla, about nine months of medicine, will cost $94,000.

FDA scientists said they approved the drug based on company studies showing Kadcyla delayed the progression of breast cancer by several months. Researchers reported last year that patients treated with the drug lived 9.6 months before death or the spread of their disease, compared with a little more than six months for patients treated with two other standard drugs, Tykerb and Xeloda.

Overall, patients taking Kadcyla lived about 2.6 years, compared with 2 years for patients taking the other drugs.

FDA specifically approved the drug for patients with advanced breast cancer who have already been treated with Herceptin and taxane, a widely used chemotherapy drug. Doctors are not required to follow FDA prescribing guidelines, and cancer researchers say the drug could have great potential in patients with earlier forms of breast cancer

Kadcyla will carry a boxed warning, the most severe type, alerting doctors and patients that the drug can cause liver toxicity, heart problems and potentially death. The drug can also cause severe birth defects and should not be used by pregnant women.

Kadcyla was developed by South San Francisco-based Genentech using drug-binding technology licensed from Waltham, Mass.-based ImmunoGen. The company developed the chemical that keeps the drug cocktail together and is scheduled to receive a $10.5 million payment from Genentech on the FDA decision. The company will also receive additional royalties on the drug's sales.

Shares of ImmunoGen Inc. rose 2 cents to $14.32 in afternoon trading. The stock has ttraded in a 52-wek range of $10.85 to $18.10.

Wall Street rebounds on HP results, Fed officials' views

NEW YORK (Reuters) - U.S. stocks rose on Friday as Dow component Hewlett-Packard surged on strong results and comments from Fed officials allayed fears that the central bank would curtail its stimulus measures.

Federal Reserve Chairman Ben Bernanke downplayed worries that the Fed has fueled asset bubbles that could hurt the economy in a private meeting with bond dealers and investors earlier this month, Bloomberg reported on Friday.

Bernanke's view helped ease fears that the central bank may end its easy money policies. Minutes from the Federal Reserve's January meeting hit markets on Wednesday as investors interpreted divergent opinions on the benefit of stimulus as a sign the measures may be halted sooner than thought.

"They are in uncharted territory with divergent views," said Jack Ablin, chief investment officer at BMO Private Bank in Chicago. "I could see some pretty heated opinions on what the ultimate outcome is, so I do believe there is dissension."

Hewlett-Packard Co shares jumped more than 12 percent and gave one of the biggest boosts to both the Dow and the S&P 500 after the personal computer maker's quarterly revenue and forecasts beat expectations. Hewlett-Packard's stock rose to $19.20 at the close, up 12.3 percent for the day.

The Dow Jones industrial average <.dji> gained 119.95 points, or 0.86 percent, to 14,000.57 at the close. The Standard & Poor's 500 Index <.spx> rose 13.18 points, or 0.88 percent, to 1,515.60. The Nasdaq Composite Index <.ixic> added 30.33 points, or 0.97 percent, to end at 3,161.82.

With Bernanke's reported comments much on their minds in Friday's session, investors will want the Fed chairman to reiterate his remarks publicly when he speaks before the Senate Banking Committee on Tuesday. That would echo comments made by two top Fed officials on Friday.

Boston Fed President Eric Rosengren and Fed Governor Jerome Powell both defended the U.S. central bank's asset-buying program, arguing that the policy helps the U.S. economy.

The S&P 500 shed 1.9 percent over the previous two sessions, its worst two-day drop since early November, following the release of the Fed's minutes on Wednesday. The selloff marked the end of seven back-to-back weeks of gains for stocks.

For the week, the S&P 500 slipped 0.3 percent and the Nasdaq lost nearly 1 percent. Only the Dow ended the week with a gain - up just 0.1 percent.

HP's results come near the end of a relatively strong earnings season in which 70 percent of S&P 500 companies beat analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters, according to Thomson Reuters data.

"Overall, the earnings supports were better than expected in this cycle," said Peter Jankovskis, co-chief investment officer at OakBrook Investments LLC in Lisle, Illinois. "We may see the market rising during the month of March."

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 6 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

But with only a handful of companies left to report earnings, investors are looking ahead to the possibility of hefty automatic budget cuts that could happen on March 1.

A large option investor appeared to be adjusting a bearish view on the SPDR S&P 500 Trust fund while locking in previously established gains, in a possible hedge ahead of the automatic budget cuts that are set to take effect at the beginning of next month. The play involved weekly puts, expiring next Friday.

"An institutional investor appears to be rolling down and increasing in size a defensive hedge timed to match the March 1 deadline for the sequester," said Henry Schwartz, president of options analytics firm Trade Alert.

The trader sold 132,000 $149 to $150 weekly put spreads for 22 cents as shares of the exchange-traded fund had traded near $151.14 on Friday morning. The transaction entailed the sale of $150 weekly puts to buy the $149 weekly puts. In addition, the investor purchased another 42,000 $149 weekly puts, which increases the size of the hedge to 174,000 contracts.

"It is likely this large position protects an existing underlying long position in a portfolio," Schwartz said.

In another political risk factor, Italians go to the polls this weekend in an election that could threaten reforms in the indebted country. Silvio Berlusconi's resurgence has thrown the vote wide open, with deep uncertainty over whether the poll can produce the strong government the country needs.

Inconclusive Greek elections last year sparked a protracted selloff and a period of uncertainty in markets.

In the tech sector, Marvell Technology Group Ltd forecast results this quarter that were largely above analysts' expectations. Marvell gained market share in the hard-disk drive and flash-storage businesses. The stock rose 4.4 percent to $9.89.

Texas Instruments Inc raised its dividend by a third and boosted its stock-buyback program, driving its stock up 5.2 percent to $34.18.

The PHLX semiconductor index <.sox> gained 2.1 percent.

"Dividends growing are another way the market's level is justified, if not especially attractive at these levels," said Rex Macey, chief investment officer of Wilmington Trust in Atlanta, who manages about $20 billion in assets.

On the downside, Abercrombie & Fitch dropped 4.5 percent to $46.86 after the youth-oriented clothing retailer reported a drop in fourth-quarter comparable sales, even as its latest quarterly earnings topped estimates.

Insurer American International Group Inc posted fourth-quarter results that beat analysts' expectations. AIG's stock advanced 3.1 percent to $38.45.

About three stocks rose for every one that fell on both the New York Stock Exchange and Nasdaq.

Around 5.8 billion shares changed hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, below the 20-day moving average of around 6.51 billion shares.

The Hunger Games: Katniss & Peeta's Victory Tour Look Revealed

02/22/2013 at 06:00 PM EST

They survived the Hunger Games – but will they survive the Victory Tour?

Sporting bridal-like attire, Katniss (Jennifer Lawrence and Peeta (Josh Hutcherson) pose for a promotional poster for the Victory Tour – which – in the Hunger Games universe – is when the victor of the annual Hunger Games tournament visits each of the fictional Panem's districts.

As true Hunger Games fans know, there is usually only one victor – but Katniss and Peeta rebelled against the Capitol in the first movie, originally opting for joint suicide instead of murder.

The softer look is a deliberate statement, meant to continue the charade that Katniss and Peeta were blinded by love when they rebelled against the rules in the arena.

The second film, Catching Fire, hits theaters Nov. 22.

Flu shot doing a poor job of protecting elderly

ATLANTA (AP) — It turns out this year's flu shot is doing a startlingly dismal job of protecting senior citizens, the most vulnerable age group.

The vaccine is proving only 9 percent effective in people 65 and older against the harsh strain of the flu that is predominant this season, the Centers for Disease Control and Prevention said Thursday.

Health officials are baffled as to why this is so. But the findings help explain why so many older people have been hospitalized with the flu this year.

Despite the findings, the CDC stood by its recommendation that everyone over 6 months get flu shots, the elderly included, because some protection is better than none, and because those who are vaccinated and still get sick may suffer less severe symptoms.

"Year in and year out, the vaccine is the best protection we have," said CDC flu expert Dr. Joseph Bresee.

Overall, across the age groups studied, the vaccine's effectiveness was found to be a moderate 56 percent, which means those who got a shot have a 56 percent lower chance of winding up at the doctor with the flu. That is somewhat worse than what has been seen in other years.

For those 65 and older, the vaccine was only 27 percent effective against the three strains it is designed to protect against, the worst level in about a decade. It did a particularly poor job against the tough strain that is causing more than three-quarters of the illnesses this year.

It is well known that flu vaccine tends to protect younger people better than older ones. Elderly people have weaker immune systems that don't respond as well to flu shots, and they are more vulnerable to the illness and its complications, including pneumonia.

But health officials said they don't know why this year's vaccine did so poorly in that age group.

One theory, as yet unproven, is that older people's immune systems were accustomed to strains from the last two years and had more trouble switching gears to handle this year's different, harsh strain.

The preliminary data for senior citizens is less than definitive. It is based on fewer than 300 people scattered among five states.

But it will no doubt surprise many people that the effectiveness is that low, said Michael Osterholm, a University of Minnesota infectious-disease expert who has tried to draw attention to the need for a more effective flu vaccine.

Among infectious diseases, flu is considered one of the nation's leading killers. On average, about 24,000 Americans die each flu season, according to the CDC.

This flu season started in early December, a month earlier than usual, and peaked by the end of year. Hospitalization rates for people 65 and older have been some of the highest in a decade, at 146 per 100,000 people.

Flu viruses tend to mutate more quickly than others, so a new vaccine is formulated each year to target the strains expected to be the major threats. CDC officials have said that in formulating this year's vaccine, scientists accurately anticipated the strains that are circulating this season.

Because of the guesswork involved, scientists tend to set a lower bar for flu vaccine. While childhood vaccines against diseases like measles are expected to be 90 or 95 percent effective, a flu vaccine that's 60 to 70 percent effective in the U.S. is considered pretty good. By that standard, this year's vaccine is OK.

For senior citizens, a flu vaccine is considered pretty good if it's in the 30 to 40 percent range, said Dr. Arnold Monto, a University of Michigan flu expert.

A high-dose version of the flu shot was recently made available for those 65 and older, but the new study was too small to show whether that has made a difference.

The CDC estimates are based on about 2,700 people who got sick in December and January. The researchers traced back to see who had gotten shots and who hadn't. An earlier, smaller study put the vaccine's overall effectiveness at 62 percent, but other factors that might have influenced that figure weren't taken into account.

The CDC's Bresee said there is a danger in providing preliminary results because it may result in people doubting — or skipping — flu shots. But the figures were released to warn older people who got shots that they may still get sick and shouldn't ignore any serious flu-like symptoms, he said.

Wall Street ends lower on growth worries

NEW YORK (Reuters) - U.S. stocks fell for a second straight day on Thursday and the S&P 500 posted its worst two-day loss since November after reports cast doubt over the health of the U.S. and euro-zone economies.

But a late-day rally helped stocks erase some of their losses with most of the pullback concentrated in the technology- heavy Nasdaq. The move suggested investors were still willing to buy on dips even after the sharp losses in the last session.

In Europe, business activity indexes dealt a blow to hopes that the euro zone might emerge from recession soon, showing the downturn across the region's businesses unexpectedly grew worse this month.

"The PMI numbers out of Europe were really a blow to the market," said Jack De Gan, chief investment officer at Harbor Advisory in Portsmouth, New Hampshire. "The market was expecting signs that recovery is still there, but the numbers just highlighted that the euro-zone problem is still persistent."

U.S. initial claims for unemployment benefits rose more than expected last week while the Federal Reserve Bank of Philadelphia said its index of business conditions in the U.S. mid-Atlantic region fell in February to the lowest in eight months.

Gains in Wal-Mart Stores Inc shares helped cushion the Dow. The shares gained 1.5 percent to $70.26 after the world's largest retailer reported earnings that beat expectations, though early February sales were sluggish.

The Dow Jones industrial average <.dji> fell 46.92 points, or 0.34 percent, to 13,880.62 at the close. The Standard & Poor's 500 Index <.spx> lost 9.53 points, or 0.63 percent, to 1,502.42. The Nasdaq Composite Index <.ixic> dropped 32.92 points, or 1.04 percent, to close at 3,131.49.

The two-day decline marked the U.S. stock market's first sustained pullback this year. The Standard & Poor's 500 has fallen 1.8 percent over the period and just managed to hold the 1,500 level on Thursday. Still, the index is up 5.3 percent so far this year.

The abrupt reversal in markets, which started on Wednesday after minutes from the Federal Reserve's January meeting suggested stimulus measures may end earlier than thought, looks set to halt a seven-week winning streak for stocks that had lifted the Dow and the S&P 500 close to all-time highs.

Wall Street will soon face another test with the upcoming debate in Washington over the automatic across-the-board spending cuts put in place as part of a larger congressional budget fight. Those cuts, set to kick in on March 1 unless lawmakers agree on an alternative, could depress the economy.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.9 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Berry Petroleum Co jumped 19.3 percent to $46.02 after oil and gas producer Linn Energy LLC said it would buy the company in an all-stock deal valued at $4.3 billion, including debt. Linn Energy shares advanced 2.8 percent to $37.68.

French, Malian forces fight Islamist rebels in Gao

GAO, Mali (Reuters) - French and Malian troops fought Islamists on the streets of Gao and a car bomb exploded in Kidal on Thursday, as fighting showed little sign of abating weeks before France plans to start withdrawing some forces.

Reuters reporters in Gao in the country's desert north said French and Malian forces fired at the mayor's office with heavy machineguns after Islamists were reported to have infiltrated the Niger River town during a night of explosions and gunfire.

French Defense Minister Jean-Yves Le Drian told a news conference in Brussels that Gao was back under control after clashes earlier in the day.

"Malian troops supported by French soldiers killed five jihadists and the situation is back to normal," he said.

In Kidal, a remote far north town where the French are hunting Islamists, residents said a car bomb killed two. A French defense ministry source reported no French casualties.

French troops dispatched to root out rebels with links to al Qaeda swiftly retook northern towns last month. But they now risk being bogged down in a guerrilla conflict as they try to help Mali's weak army counter bombings and raids.

"There was an infiltration by Islamists overnight and there is shooting all over the place," Sadou Harouna Diallo, Gao's mayor, told Reuters by telephone earlier in the day, saying he was not in his office at the time.

Gao is a French hub for operations in the Kidal region, about 300 km (190 miles) northeast, where many Islamist leaders are thought to have retreated and foreign hostages may be held.

"They are black and two were disguised as women," a Malian soldier in Gao who gave his name only as Sergeant Assak told Reuters during a pause in heavy gunfire around Independence Square.

Six Malian military pickups were deployed in the square and opened fire on the mayor's office with the heavy machineguns. Two injured soldiers were taken away in an ambulance.

French troops in armored vehicles later joined the battle as it spilled out into the warren of sandy streets, where, two weeks ago, they also fought for hours against Islamists who had infiltrated the town via the nearby river.

Helicopters clattered over the mayor's office, while a nearby local government office and petrol station was on fire.

A Gao resident said he heard an explosion and then saw a Malian military vehicle on fire in a nearby street.

Paris has said it plans to start withdrawing some of its 4,000 troops from Mali next month. But rebels have fought back against Mali's weak and divided army, and African forces due to take over the French role are not yet in place.

Islamists abandoned the main towns they held but French and Malian forces have said there are pockets of Islamist resistance across the north, which is about the size of France.

CAR BOMB

Residents reported a bomb in the east of Kidal on Thursday.

"It was a car bomb that exploded in a garage," said one resident who went to the scene but asked not to be named.

"The driver and another man were killed. Two other people were injured," he added.

A French defense ministry official confirmed there had been a car bomb but said it did not appear that French troops, based at the town's airport, had been targeted.

Earlier this week, a French soldier was killed in heavy fighting north of Kidal, where French and Chadian troops are hunting Islamists in the Adrar des Ifoghas mountains, which border Algeria.

Operations there are further complicated by the presence of separatist Tuareg rebels, whose rebellion triggered the fighting in northern Mali last year but were sidelined by the better-armed Islamists.

Having dispatched its forces to prevent an Islamist advance south in January, Paris is eager not to become bogged down in a long-term conflict in Mali. But their Malian and African allies have urged French troops not to pull out too soon.
