Cameroon, Nigeria officials deny French hostages freed

YAOUNDE (Reuters) - The fate of seven French tourists seized in Cameroon by suspected Nigerian Islamist militants was unclear on Thursday after government officials denied French media reports that they had been freed.

The hostages, four children and three adults, were captured this week while on an excursion to the Waza national park near Cameroon's border with Nigeria.

Several French media reported earlier on Thursday that the hostages had been found alive in a house in northern Nigeria and freed.

"The hostages are safe and sound and are in the hands of Nigerian authorities," BFMTV quoted a Cameroon army officer as saying.

"This is a crazy rumor that we cannot confirm. We do not know where is it coming from," Cameroon Communications Minister Issa Tchiroma Bakary said by telephone from the capital Yaounde.

Sagir Musa, a spokesman for Nigeria's military, told Reuters the report was "not true."

Kader Arif, France's minister for veterans' affairs, told parliament on Thursday that the seven hostages had been released but retracted his statement minutes later, saying he had been quoting media reports and there was no official confirmation.

It was the first case of foreigners being seized by suspected Islamist militants in the mainly Muslim north of Cameroon, a former French colony.

The region is seen as being within the operational sphere of Nigerian sect Boko Haram and another Islamist militant group, Ansaru.

The threat to French nationals in the region has grown since France deployed thousands of troops to nearby Mali to root out al Qaeda-linked Islamists who took control of the country's north last year.

The kidnapping in Cameroon brought to 15 the number of French citizens being held in West Africa.

French diplomatic sources said the government would not confirm the hostages had been released until it had physical proof, or until they were in French hands.

Oscars Flashback: Catherine Zeta-Jones 2003

Catherine Zeta-Jones had quite possibly the best year of her adult life in 2003. Following the rampant success of her musical film Chicago, the Welsh actress was nominated for her first Oscar. However, an Oscar wasn't the only award that life adorned her with that year.

Zeta-Jones arrived to the 2003 Oscars eight months pregnant with her second child. While she was less than a month away from giving birth, she nevertheless performed a number from Chicago with her co-star Queen Latifah, which made it an even more memorable night for her.

After performing, Zeta-Jones was granted the Oscar for which she was nominated and was on cloud nine in the press room after receiving the award.

"I'm still in shock," the then-33-year-old actress says. "...I just know that a dream came true for me tonight. ...I'm dumbstruck. ...Without anyone seeing this movie, it was probably the most amazing experience of my life, and this [award going] part and parcel with that experience is just overwhelming."

Knowing that it would prove to be a once-in-a-lifetime experience, she wanted to cherish every moment of it.

"I need to write it all down tomorrow to remember this night," she adds. "I can't even remember my own name right now."

A month from giving birth to her second child, Zeta-Jones, the second child of Patricia and David James Jones, reveals that she had just gotten off with her mom in her native Wales, where it was well into the early hours of the morning.

"My mother's still awake. I just spoke to her and it's some god-awful hour," she says. "This is something that I'll be taking back home with me and showing it off to all my family and friends in Wales."

That wouldn't be the only thing she would be showing off to her loved ones back home.

Adults get 11 percent of calories from fast food

ATLANTA (AP) — On an average day, U.S. adults get roughly 11 percent of their calories from fast food, a government study shows.

That's down slightly from the 13 percent reported the last time the government tried to pin down how much of the American diet is coming from fast food. Eating fast food too frequently has been seen as a driver of America's obesity problem.

For the research, about 11,000 adults were asked extensive questions about what they ate and drank over the previous 24 hours to come up with the results.

Among the findings:

— Young adults eat more fast food than their elders; 15 percent of calories for ages 20 to 39 and dropping to 6 percent for those 60 and older.

— Blacks get more of their calories from fast-food, 15 percent compared to 11 percent for whites and Hispanics.

— Young black adults got a whopping 21 percent from the likes of Wendy's, Taco Bell and KFC.

The figures are averages. Included in the calculations are some people who almost never eat fast food, as well as others who eat a lot of it.

The survey covers the years 2007 through 2010 and was released Thursday by the Centers for Disease Control and Prevention. The authors couldn't explain why the proportion of calories from fast food dropped from the 13 percent found in a survey for 2003 through 2006.

One nutrition professor cast doubts on the latest results, saying 11 percent seemed implausibly low. New York University's Marion Nestle said it wouldn't be surprising if some people under-reported their hamburgers, fries and milkshakes since eating too much fast food is increasingly seen as something of a no-no.

"If I were a fast-food company, I'd say 'See, we have nothing to do with obesity! Americans are getting 90 percent of their calories somewhere else!'" she said.

The study didn't include the total number of fast-food calories, just the percentage. Previous government research suggests that the average U.S. adult each day consumes about 270 calories of fast food — the equivalent of a small McDonald's hamburger and a few fries.

The new CDC study found that obese people get about 13 percent of daily calories from fast food, compared with less than 10 percent for skinny and normal-weight people.

There was no difference seen by household income, except for young adults. The poorest — those with an annual household income of less than $30,000 — got 17 percent of their calories from fast food, while the figure was under 14 percent for the most affluent 20- and 30-somethings with a household income of more than $50,000.

That's not surprising since there are disproportionately higher numbers of fast-food restaurants in low-income neighborhoods, Nestle said.

Fast food is accessible and "it's cheap," she said.

Bulgarian government resigns amid growing protests

SOFIA (Reuters) - Bulgaria's government resigned on Wednesday after violent nationwide protests against high power prices, joining a long list of European administrations felled by austerity during Europe's debt crisis.

Prime Minister Boiko Borisov, a former bodyguard who swept to power in 2009 on pledges to root out corruption and raise living standards in the European Union's poorest member, now faces a tough task to prop up eroding support ahead of a probable early election.

Wage and pension freezes and tax hikes have bitten deep in a country where living standards are less than half the EU average and tens of thousands of Bulgarians have rallied in protests that have turned violent, chanting "Mafia" and "Resign".

On Tuesday, 11 people were hospitalized - including one man bleeding heavily from the head - and 11 arrested after protesters threw flares at police, who fought demonstrators with shields and truncheons.

"I will not participate in a government under which police are beating people," Borisov, who began his career guarding the Black Sea state's communist dictator Todor Zhivkov, said as he announced his resignation on Wednesday.

Parliament is expected to accept the resignation later in the day.

The spark for the protests was high electricity bills, after the government raised prices by 13 percent last July. But it quickly spilled over into wider frustration with Borisov's domineering manner and unpredictable decision making.

The prime minister made sacrifices in an attempt to cling on, sacking his finance minister, cutting power prices and risking a diplomatic row with the Czech Republic by punishing foreign-owned companies, a move that conflicted with EU norms on protection of investors and due process.

Borisov's rightist GERB party is the dominant faction in parliament but will not take part in talks to form a new government, Interior Minister Tsvetan Tsvetanov said, indicating that an election planned for July will now be held early.

"He made my day," student Borislav Hadzhiev, 21, in central Sofia said, commenting on Borisov's resignation. "The truth is that we're living in an extremely poor country."

IRE

GERB's popularity has held up well and it still leads, just, in the polls, largely because budget cutbacks have been relatively mild compared with those in many other European countries. Salaries and pensions were frozen rather than cut.

But the last opinion poll, taken before protests grew last weekend already showed the opposition Socialists were nearly tied with the ruling party and analysts said the protests had boosted the Socialists' chances.

Unemployment in the country of 7.3 million is far from the highs hit in the decade after the end of communism but remains at 11.9 percent and average salaries are stuck at around 800 levs ($550) a month.

Millions have emigrated in search of a better life, leaving swathes of the country depopulated and little hope for those who remain.

The measures announced this week has also put the country on a collision course with the EU and financial investors without easing the tension at home.

Czech Prime Minister Petr Necas demanded an explanation from Bulgaria and accused it of "politicizing" the power sector by threatening to revoke the electricity distribution license of central Europe's largest listed company CEZ, 70 percent of which is owned by the Czech state.

There have also been fines for another Czech company, Energo-Pro and Austria's EVN.

The precedent is unlikely to encourage other foreign investors, who already have to navigate complicated bureaucracy and widespread corruption and organized crime if they want to take advantage of Bulgaria's 16-percent flat tax rate.

"The resignation is the only responsible move," said Kantcho Stoychev, an analyst with pollster Gallup International. "It also gives Borisov some legitimacy to stay in political life in the future, despite the violent police actions last night."

Future science: Using 3D worlds to visualize data

CHICAGO (AP) — Take a walk through a human brain? Fly over the surface of Mars? Computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality with a wraparound virtual world where a researcher wearing 3D glasses can do all that and more.

In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, conveying a dizzying sense of being able to touch what's not really there.

As far back as 1950, sci-fi author Ray Bradbury imagined a children's nursery that could make bedtime stories disturbingly real. "Star Trek" fans might remember the holodeck as the virtual playground where the fictional Enterprise crew relaxed in fantasy worlds.

The Illinois computer scientists have more serious matters in mind when they hand visitors 3D glasses and a controller called a "wand." Scientists in many fields today share a common challenge: How to truly understand overwhelming amounts of data. Jason Leigh, co-inventor of the CAVE2 virtual reality system, believes this technology answers that challenge.

"In the next five years, we anticipate using the CAVE to look at really large-scale data to help scientists make sense of that information. CAVEs are essentially fantastic lenses for bringing data into focus," Leigh said.

The CAVE2 virtual world could change the way doctors are trained and improve patient care, Leigh said. Pharmaceutical researchers could use it to model the way new drugs bind to proteins in the human body. Car designers could virtually "drive" their new vehicle designs.

Imagine turning massive amounts of data — the forces behind a hurricane, for example — into a simulation that a weather researcher could enlarge and explore from the inside. Architects could walk through their skyscrapers before they are built. Surgeons could rehearse a procedure using data from an individual patient.

But the size and expense of room-based virtual reality systems may prove insurmountable barriers to widespread use, said Henry Fuchs, a computer science professor at the University of North Carolina at Chapel Hill, who is familiar with the CAVE technology but wasn't involved in its development.

While he calls the CAVE2 "a national treasure," Fuchs predicts a smaller technology such as Google's Internet-connected eyeglasses will do more to revolutionize medicine than the CAVE. Still, he says large displays are the best way today for people to interact and collaborate.

Believers include the people at Marshalltown, Iowa-based Mechdyne Corp., which has licensed the CAVE2 technology for three years and plans to market it to hospitals, the military and in the oil and gas industry, said Kurt Hoffmeister of Mechdyne.

In Chicago, researchers and graduate students are creating virtual scenarios for testing in the CAVE2. The Mars flyover is created from real NASA data. The brain tour is based on the layout of blood vessels in a real patient.

Brain surgeon Ali Alaraj remembered the first time he viewed the brain using the CAVE2.

"You can walk between the blood vessels," said the University of Illinois College of Medicine neurosurgeon. "You can look at the arteries from below. You can look at the arteries from the side.... That was science fiction for me."

Would doctors process information faster with fewer errors using CAVE2? That's the question behind a proposed study that would compare CAVE2 to conventional methods of detecting brain aneurysms and determining proper treatment, said Andreas Linninger, UIC professor of bioengineering, chemical engineering and computer science.

But it's not all serious business at the lab.

In his spare time during the past two years, research assistant Arthur Nishimoto has been programming the CAVE2 computer with the specifications for the fictional Starship Enterprise. He now can walk around his life-size recreation of the TV spacecraft.

The original technology, introduced in the early 1990s, was called CAVE, which stood for Cave Automatic Virtual Environment and also cleverly referred to Plato's cave, the philosopher's analogy about shadows and reality. It was named by former lab co-directors Tom DeFanti and Dan Sandin.

The second generation of the CAVE, invented by Leigh and his collaborator Andy Johnson, has higher resolution. The project was funded by the National Science Foundation and the Department of Energy.

"It's fantastic to come to work. Every day is like getting to live a science fiction dream," Leigh said. "To do science in this kind of environment is absolutely amazing."

Wall Street set for flat open after data, Fed minutes on tap

NEW YORK (Reuters) - U.S. stock index futures edged lower on Wednesday, ahead of data on the housing market and inflation, as well as minutes from the Federal Open Market Committee's January meeting.

Housing starts and permits for January along with the January producer price index are due at 8:30 a.m. (1330 GMT).

Economists in a Reuters survey forecast the housing starts data to show a 925,000-unit annualized rate in January versus 954,000 in December, and a total of 915,000 permits in January compared with 909,000 in the prior month.

PPI is expected to show a 0.4 percent rise after a 0.3 percent drop in December. Excluding volatile food and energy items, PPI is expected to rise 0.2 percent versus a 0.1 percent increase in December.

Later in the session, investors will look to the minutes from the Fed's January meeting for any clues on how long the current monetary policy will remain in effect.

"We have several economic pieces of news today and of course the one that is eyed the most is going to be the FOMC minutes," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.

"Housing starts is in play and the earlier data probably will set the stage for the market to perhaps continue yesterday's rally but the key will be the FOMC minutes."

U.S. stocks moved closer to all-time highs on Tuesday, as the ongoing flurry of merger activity to start the year has helped buoy equities from a pullback.

An expected deal that helped lift the market on Tuesday was confirmed on Wednesday when Office Depot Inc said it had reached a definitive deal to buy smaller rival OfficeMax Inc in a bid to get more clout with suppliers and better compete against rival Staples Inc .

Office Depot shares jumped 14.5 percent to $5.75 before the opening bell while OfficeMax surged 15.4 percent to $15. Staples shares gained 2.7 percent to $15.05.

The S&P 500 <.spx> is up 7.4 percent for the year, fueled by legislators' ability to sidestep an automatic implementation of spending cuts on tax hikes on January 1, better-than-expected corporate earnings and modestly improving economic data that has been tepid enough for the Fed to maintain its stimulus policy.

S&P 500 futures slipped 1.4 points and were slightly below fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures lost 1 point, and Nasdaq 100 futures shed 3.75 points.

As earnings season winds down, S&P 500 companies set to report include Devon Energy Corp and Fluor Corp .

Toll Brothers Inc lost 4.6 percent to $35.20 in premarket trade after the largest luxury homebuilder in the United States, reported first-quarter results well below analysts' estimates.

SodaStream dropped 5 percent to $49.82 in premarket after the seller of home carbonated drink maker machines posted fourth-quarter earnings and provided a 2013 outlook.

According to Thomson Reuters data through Tuesday morning, of the 391 companies in the S&P 500 that have reported results, 70.1 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.6 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

European shares dipped on Wednesday, consolidating after a steep rally in the previous session as investors were confronted with news of weak earnings, though some expected further near-term gains. <.eu/>

Asian shares scaled their highest levels since August 2011 after an improving global economic outlook whetted investor appetite for risk, while the yen firmed amid doubts over Japan's commitment to drastic reflation.

Venezuela's Maduro would win if Chavez goes: poll

CARACAS (Reuters) - Venezuelan Vice President Nicolas Maduro would comfortably win a presidential election should his boss Hugo Chavez's cancer force him out of power, according to an opinion poll.

The first survey on such a scenario, by local pollster Hinterlaces, gave Maduro a potential 50 percent of votes, compared to 36 percent for opposition leader Henrique Capriles.

Chavez returned to Venezuela on Monday after a long stay in Cuba to continue treatment at home for the disease that is jeopardizing his 14-year socialist rule of the South American OPEC nation.

He has named 50-year-old former bus driver and union activist Maduro as his preferred successor. But Capriles, 40, a center-left state governor who lost to Chavez in a presidential vote last year, would likely run again.

Chavez still has not said a word in public since his December 11 operation in Cuba, and Venezuelans were debating on Tuesday the various possible scenarios after his homecoming - from full recovery, to resignation, or even death from the cancer.

Should Chavez be forced out, Venezuela's constitution stipulates an election must be held within 30 days.

Capriles, who crossed swords with Hinterlaces at various points during the presidential election, again mocked its director, Oscar Schemel, as being biased against him.

"That man is not a pollster, he's on the government's payroll," Capriles told local TV.

"He said in December I would lose the Miranda governorship," he added, referring to his defeat of government heavyweight Elias Jaua, now foreign minister, in that local race.

Opinion surveys are notoriously controversial and divergent in Venezuela, with both sides routinely accusing pollsters of being in the pocket of the other.

Hinterlaces surveyed 1,230 people between January 30-February 9.
