Fed minutes short-circuit Wall Street rally

NEW YORK (Reuters) - U.S. stocks dipped on Thursday after signs the Federal Reserve has growing concern about its highly stimulative monetary policy, giving investors reason to pull back after a two-day rally.

The minutes from the Fed's December policy meeting, released on Thursday, showed increasing reticence about adding to the central bank's $2.9 trillion balance sheet, which it expanded sharply in response to the financial crisis and recession of 2007-2009.

Some policymakers thought asset buying should be slowed or stopped before the end of 2013 while others highlighted the need for further stimulus. The Fed's policy of easy credit has helped push the S&P 500 to a 13.4 percent gain in 2012. Ending that policy would remove an incentive for investors to purchase riskier assets like stocks.

"The surprise was the changes to duration and extent of that program in 2013, but given the tone in previous Fed meeting minutes, it should not have been an entire surprise," said Fred Dickson, chief market strategist at D.A. Davidson & Co. in Lake Oswego, Oregon.

Despite the concerns about the effects of its asset purchases, the Fed look set to continue its open-ended stimulus program for now.

Stocks pushed the S&P 500 index 4.3 percent higher in the previous two sessions. On Thursday investors turned their focus to coming battles in Congress, including the likelihood of bitter fights over budget cuts and raising the federal debt ceiling.

"We were definitely technically extended and ripe for a little bit of a consolidation and today is very orderly - traders and investors are still trying to digest the language and the details from the 2012 taxpayer act," Dickson said.

The Dow Jones industrial average <.dji> dropped 21.19 points, or 0.16 percent, to 13,391.36. The Standard & Poor's 500 Index <.spx> shed 3.05 points, or 0.21 percent, to 1,459.37. The Nasdaq Composite Index <.ixic> lost 11.70 points, or 0.38 percent, to 3,100.57.

Economic data showed U.S. private-sector employers shrugged off a looming budget crisis and stepped up hiring in December, offering further evidence of underlying strength in the economy as 2012 ended.

The government's broader monthly payrolls report, due on Friday, is expected to show the economy created 150,000 jobs compared with 146,000 in November, according to a Reuters poll. The U.S. unemployment rate is seen holding steady at 7.7 percent.

Retailers advanced after several major companies in the sector beat expectations of modest sales increases in December, with the S&P retail index <.spxrt> up 0.4 percent.

Shares in Costco Wholesale Corp rose 1 percent to $102.49 after the company reported a better-than-expected 9 percent rise in December sales at stores open at least a year.

Gap Inc stock climbed 2.3 percent to $32.09 following news that the retailer will buy women's fashion boutique Intermix Inc, the Wall Street Journal reported.

Family Dollar Stores Inc stumbled 13 percent to $55.74 on the company's report of lower-than-expected quarterly profit.

Volume was relatively strong, with about 6.68 billion shares traded on the New York Stock Exchange, NYSE MKT and Nasdaq, slightly above the 2012 daily average of 6.42 billion.

Advancing stocks outnumbered declining ones on the NYSE by 1,692 to 1,321, while on the Nasdaq, decliners beat advancers 1,287 to 1,187.

Hezbollah Leader Urges Lebanon to Aid in a Solution for Syria

BEIRUT, Lebanon — Hassan Nasrallah, the leader of Hezbollah, openly urged the Lebanese government on Thursday to take a more active role in finding a political solution to the civil war in neighboring Syria and to open its border to refugees to avert further bloodshed.

Mr. Nasrallah, the head of the Shiite militant movement in Lebanon, addressed a ceremony in the town of Baalbek, near the Syrian border, by video link, underscoring the urgency of the need for a resolution. “I call on the Lebanese government to develop its position on the Syrian crisis,” Mr. Nasrallah said, speaking in observance of Arbaeen, the end of a 40-day mourning period for the death of Hussein, a grandson of the Prophet Muhammad. “Lebanon must exert pressure for a political solution and a political dialogue in Syria. If military operations continue in Syria, it will be a long and bloody battle.”

Mr. Nasrallah has only occasionally commented on events in Syria during speeches.

After the Syrian uprising started in March 2011, the prime minister of Lebanon, Najib Mikati, declared that the country would pursue a line of “disassociation” from either side, a position apparently aimed at keeping the fighting from spilling across the border. Nevertheless, there have been occasional flare-ups inside Lebanon and episodes of cross-border shelling.

Mr. Nasrallah also spoke as reports emerged of the escalating death toll among civilians. As the conflict now approaches the end of its second year, multiple reports flow in daily of civilian casualties from airstrikes, gunfire and shelling. This week, the Syrian Observatory for Human Rights, a rebel group that tracks the war from Britain, reported 45,000 deaths, mostly civilian, since the conflict began, while United Nations’ human rights chief, Navi Pillay, set the number at more than 60,000, based on a new analysis of the broadest data to date.

Mr. Nasrallah also touched on the refugee problem. Last month the United Nations appealed for $1.5 billion in new aid to handle the humanitarian crisis created by the violence and predicted that the number of Syrian refugees would double to more than one million in the next six months. There are now about 160,000 registered refugees in Lebanon alone. Jordan has at least 150,000, Turkey has 140,000, Iraq more than 65,000, and Egypt more than 10,000. How many more are unregistered is uncertain.

While Mr. Nasrallah said that the best solution for the refugees would be a halt to the violence, he said: “We should deal with the Syrian refugees with purely humanitarian responsibility, without politicization of the issue. Attention must be paid to the displaced families, whatever their political background.”

“We, as Lebanon, cannot close the border with Syria, with our understanding of the political, security and economic risks for this massive displacement,” he said.

Mr. Nasrallah also emphasized the deep connections between Lebanon and Syria.

“We must recognize that Lebanon is a country mostly affected by what is going on around it, especially in Syria, because of sectarian and political diversity, and conflict of interest,” he said.

Mr. Nasrallah and the Hezbollah group have kept their loyalty to Syria’s president, Bashar al-Assad, an Alawite, relatively low key. Fighters from the movement cross the border to fight for the president, and some have been sent to protect areas important to Shiites, analysts say. With the frontier between Syria and Lebanon weakly controlled, there are concerns that it could be the focus of confrontations with Sunni fighters in a possible regional conflict.

Hezbollah officials strongly deny that the group is fighting in Syria, although Mr. Nasrallah has said that Hezbollah was providing assistance to help protect villagers of Lebanese heritage in Syrian villages along the border.

Efforts to find a political solution in Syria by Russia, the United Nations’ special envoy and others have appeared to founder in recent days as neither Mr. Assad nor his opponents have expressed a willingness to make concessions to end the bloody conflict. Nor has there been any change in the case of James Foley, a freelance reporter for Agence France-Presse, the Global Post Web site and other media outlets who was kidnapped on Nov. 22 by unidentified gunmen in northwest Syria. His family made his disappearance public on Wednesday. Mr. Foley had survived detention by government forces in Libya while covering the conflict there.

Samsung and Apple are still the only winners in the mobile market

The duopoly of the U.S. mobile market intensified dramatically in 2012. Despite increased efforts from Motorola, LG (066570), HTC (2498), Nokia (NOK) and Microsoft (MSFT) to gain market share, Samsung (005930) and Apple (AAPL) continue to steal customers away from every other company. During a three-month period ending in November, comScore found that Samsung’s lead in the U.S. smartphone market increased 1.2 percentage points for a controlling 26.9% share. Apple’s smartphone market share grew from 17.1% to 18.5%, gaining 1.4 points following the launch of the iPhone 5. Rounding out the top-five were LG, Motorola and HTC, all of which saw their market shares decrease from August. LG fell 0.7 points to 17.5%, Motorola dropped 0.8 points to 10.4% and HTC’s market share decreased from 6.3% to 5.9%.

[More from BGR: Samsung confirms plan to begin inching away from Android]

[More from BGR: ‘iPhone 5S’ to reportedly launch by June with multiple color options and two different display sizes]

The research firm found that 123.3 million people in the U.S. owned smartphones during the period, an increase of 6% since August. A majority of devices, 53.7%, were powered by Google’s (GOOG) Android operating system, which saw growth of 1.1 percentage points. Apple’s iOS market share increased 0.7 percentage points to 35%.

2012 was a transitional year for Research in Motion (RIMM) and Microsoft. Both companies spent most of the year preparing new operating systems. RIM will unveil its BlackBerry 10 operating system later this month and devices powered by Windows Phone 8 launched this past November. As a result, both companies saw lost share toward the end of 2012; RIM’s BlackBerry platform ranked third with a 7.3% share, down from 8.3% in August, and Microsoft’s operating system dropped 0.6 percentage points to a 3% share of the market.

Anne Hathaway Says Falling Fast for Adam Shulman Was 'Scary'

By Andrea Billups

01/03/2013 at 05:45 PM EST

Adam Shulman and Anne Hathaway

Dave Allocca/Startraks

Anne Hathaway believes in love at first sight – in fact, she experienced it with her husband, Adam Shulman.

"I knew from the second I met him that he was the love of my life," the Les Miserables star says in an interview with Harper's Bazaar UK. "I also knew that I couldn't have met him at a worse time."

Hathaway says the timing was bad because she found it difficult to trust after a previous breakup.

"I took my trust out for a ridiculous joyride with him," Hathaway, 30, told the magazine for its February issue of falling for Shulman, 31. "It was scary. But as the days wore on it kept getting better and better. I found that the love I found for him made me more trusting of everyone, and the more I started to see who I had become."

Since marrying in Big Sur, Calif., in September, Hathaway says she's as happy as ever.

"He walks into a room, and I light up. I can't help it," says the Golden Globe nominee. "A few days into [filming Les Miserables], I said, 'I'm having too much fun, I just want to play with you and I need to be really sad right now.' "

Hathaway, who looks sexy in a strapless gown on the cover of Harper's Bazaar UK, says she never loved her good-girl image.

"I'm not Rihanna; I'm not cool," she says. "I was seen as this bizarre-world, good-girl cartoon that I in no way identified with – very vanilla, very sweet, very accessible and not interesting. I had no grit, no sex appeal."

Brain image study: Fructose may spur overeating

This is your brain on sugar — for real. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating.

After drinking a fructose beverage, the brain doesn't register the feeling of being full as it does when simple glucose is consumed, researchers found.

It's a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role. These sugars often are added to processed foods and beverages, and consumption has risen dramatically since the 1970s along with obesity. A third of U.S. children and teens and more than two-thirds of adults are obese or overweight.

All sugars are not equal — even though they contain the same amount of calories — because they are metabolized differently in the body. Table sugar is sucrose, which is half fructose, half glucose. High-fructose corn syrup is 55 percent fructose and 45 percent glucose. Some nutrition experts say this sweetener may pose special risks, but others and the industry reject that claim. And doctors say we eat too much sugar in all forms.

For the study, scientists used magnetic resonance imaging, or MRI, scans to track blood flow in the brain in 20 young, normal-weight people before and after they had drinks containing glucose or fructose in two sessions several weeks apart.

Scans showed that drinking glucose "turns off or suppresses the activity of areas of the brain that are critical for reward and desire for food," said one study leader, Yale University endocrinologist Dr. Robert Sherwin. With fructose, "we don't see those changes," he said. "As a result, the desire to eat continues — it isn't turned off."

What's convincing, said Dr. Jonathan Purnell, an endocrinologist at Oregon Health & Science University, is that the imaging results mirrored how hungry the people said they felt, as well as what earlier studies found in animals.

"It implies that fructose, at least with regards to promoting food intake and weight gain, is a bad actor compared to glucose," said Purnell. He wrote a commentary that appears with the federally funded study in Wednesday's Journal of the American Medical Association.

Researchers now are testing obese people to see if they react the same way to fructose and glucose as the normal-weight people in this study did.

What to do? Cook more at home and limit processed foods containing fructose and high-fructose corn syrup, Purnell suggested. "Try to avoid the sugar-sweetened beverages. It doesn't mean you can't ever have them," but control their size and how often they are consumed, he said.

A second study in the journal suggests that only severe obesity carries a high death risk — and that a few extra pounds might even provide a survival advantage. However, independent experts say the methods are too flawed to make those claims.

The study comes from a federal researcher who drew controversy in 2005 with a report that found thin and normal-weight people had a slightly higher risk of death than those who were overweight. Many experts criticized that work, saying the researcher — Katherine Flegal of the Centers for Disease Control and Prevention — painted a misleading picture by including smokers and people with health problems ranging from cancer to heart disease. Those people tend to weigh less and therefore make pudgy people look healthy by comparison.

Flegal's new analysis bolsters her original one, by assessing nearly 100 other studies covering almost 2.9 million people around the world. She again concludes that very obese people had the highest risk of death but that overweight people had a 6 percent lower mortality rate than thinner people. She also concludes that mildly obese people had a death risk similar to that of normal-weight people.

Critics again have focused on her methods. This time, she included people too thin to fit what some consider to be normal weight, which could have taken in people emaciated by cancer or other diseases, as well as smokers with elevated risks of heart disease and cancer.

"Some portion of those thin people are actually sick, and sick people tend to die sooner," said Donald Berry, a biostatistician at the University of Texas MD Anderson Cancer Center in Houston.

The problems created by the study's inclusion of smokers and people with pre-existing illness "cannot be ignored," said Susan Gapstur, vice president of epidemiology for the American Cancer Society.

A third critic, Dr. Walter Willett of the Harvard School of Public Health, was blunter: "This is an even greater pile of rubbish" than the 2005 study, he said. Willett and others have done research since the 2005 study that found higher death risks from being overweight or obese.

Flegal defended her work. She noted that she used standard categories for weight classes. She said statistical adjustments were made for smokers, who were included to give a more real-world sample. She also said study participants were not in hospitals or hospices, making it unlikely that large numbers of sick people skewed the results.

"We still have to learn about obesity, including how best to measure it," Flegal's boss, CDC Director Dr. Thomas Frieden, said in a written statement. "However, it's clear that being obese is not healthy - it increases the risk of diabetes, heart disease, cancer, and many other health problems. Small, sustainable increases in physical activity and improvements in nutrition can lead to significant health improvements."

Wall Street starts new year with a bang after "cliff" deal

NEW YORK (Reuters) - Stocks kicked off the new year with their best day in over a year on Wednesday, sparked by relief over a last-minute deal in Washington to avert the "fiscal cliff" of tax hikes and spending cuts that threatened to derail the economy's growth.

In 2013's first trading session, the S&P 500 achieved its biggest one-day gain since December 20, 2011, pushing the benchmark index to its highest close since September 14.

Concerns over Washington's ability to sidestep the cliff had driven the S&P 500 down for five straight sessions, before signs that a resolution was near sent the benchmark index higher on the final trading session of 2012.

The CBOE Volatility Index or the VIX <.vix>, Wall Street's favorite gauge of investor anxiety, dropped 18.5 percent to 14.68 at the close. The VIX has fallen 35.4 percent over the past two sessions, the biggest 2-day percentage drop in the history of the index.

The Dow Jones industrial average <.dji> jumped 308.41 points, or 2.35 percent, to 13,412.55 at the close. The Standard & Poor's 500 Index <.spx> gained 36.23 points, or 2.54 percent, to finish at 1,462.42. The Nasdaq Composite Index <.ixic> climbed 92.75 points, or 3.07 percent, to end at 3,112.26.

U.S. markets were closed on Tuesday for New Year's Day.

Market breadth reflected the strong rally, with 10 stocks rising for every one that fell on the New York Stock Exchange. All 10 of the S&P 500 industry sector indexes gained at least 1 percent. The S&P financial index <.gspf> shot up 2.9 percent.

The S&P Information Technology index <.gspt> gained 3.2 percent, including Hewlett-Packard , which climbed 5.4 percent to $15.02. HP's gain followed a miserable 2012 when the stock fell nearly 45 percent as one of the S&P 500's worst performers for 2012.

On Tuesday, Congress passed a bill to prevent huge tax hikes and delay spending cuts that would have pushed the world's largest economy off a "fiscal cliff" and possibly into recession.

The vote avoided steep income-tax increases for a majority of Americans, but failed to resolve a major showdown over cutting the budget deficit, leaving investors and businesses with only limited clarity about the outlook for the economy. Spending cuts of $109 billion in military and domestic programs were temporarily delayed, and another fight over raising the U.S. debt limit also looms.

"We got through the fiscal cliff. The next big thing, and probably more contentious thing, is negotiating the debt ceiling and possibly entitlement reform in early 2013," said Jim Russell, senior equity strategist for U.S. Bank Wealth Management in Cincinnati.

Hard choices about budget cuts and the critical need to raise the debt ceiling will confront Congress about the same time in two months "so the fur will be flying," Russell said.

U.S. stocks ended 2012 with the S&P 500 up 13.4 percent for the year, as investors largely shrugged off worries about the fiscal cliff. For the year, the Dow gained 7.3 percent and the Nasdaq jumped 15.9 percent.

Bank shares rose following news that U.S. regulators are close to securing another multibillion-dollar settlement with the largest banks to resolve allegations that they unlawfully cut corners when foreclosing on delinquent borrowers.

Bank of America Corp rose 3.7 percent to $12.03 and Citigroup Inc gained 4.3 percent to $41.25. The KBW bank index <.bkx> rose 3.2 percent.

Shares of Zipcar Inc surged 47.8 percent to $12.18 after Avis Budget Group Inc said it would buy Zipcar for about $500 million in cash to compete with larger rivals Hertz and Enterprise Holdings Inc. Avis advanced 4.8 percent to $20.77.

Shares of Apple rose 3.2 percent to $549.03, helping to lift the S&P information technology index <.gspt> up 3.2 percent following a report that the most valuable tech company has started testing a new iPhone and a new version of its iOS software.

Economic data from the Institute for Supply Management showed U.S. manufacturing ended 2012 on an upswing despite fears about the fiscal cliff, but the Commerce Department reported that construction spending fell in November for the first time in eight months.

Volume was heavy, with about 7.8 billion shares traded on the New York Stock Exchange, the NYSE MKT and the Nasdaq, well above the 2012 daily average of 6.42 billion.

Dozens of Syrians Killed in Explosions Around Damascus

Andoni Lubaki/Associated Press

Rebel fighters patrol a neighborhood in Aleppo on Wednesday.

BEIRUT, Lebanon — Dozens of Syrians were killed or wounded in an explosion at a gas station east of Damascus, the Syrian capital, on Wednesday, and explosions in another Damascus suburb killed at least six people and wounded many more, including women and children, according to videos and reports from antigovernment activists.

The violence came as the United Nations released a study showing that more than 60,000 people had been killed in Syria’s 22-month-old conflict, a third higher than estimates by antigovernment activist groups.

Also on Wednesday, the family of James Foley, a reporter for the Global Post Web site, announced that Mr. Foley had been kidnapped on Nov. 22 by unidentified gunmen in northwest Syria. Mr. Foley had survived an abduction in Libya while covering the conflict there.

A recent flurry of diplomatic activity by Russia, the United Nations’ special envoy and others aimed at finding a political solution appeared to founder in recent days as neither Bashar al-Assad, the Syrian president, nor his opponents expressed a willingness to make concessions to end the bloody conflict.

The explosion near Damascus, which witnesses blamed on an airstrike, took place in a heavily contested suburban area. It hit a gas station where scores of people had lined up for fuel, which had just become available there after about a month, residents said. Videos posted by antigovernment activists showed charred bodies.

One man, using the nickname Abu Fuad, said in a telephone interview that he had just filled up his gas tank and was driving away when he heard the screech of fighter jets.

He was less than a quarter mile away when he heard the explosions, he said.

“There were many cars waiting their turn,” he said. “Yesterday, we heard that the government sent fuel to the gas station here, so all the people around came to fill up their cars.”

In a sign of the depth of distrust the conflict has spawned, Abu Fuad suggested that restocking the station was a government ruse. “They sent fuel as a trap,” he said.

In northern Syria, rebels used rockets to attack the Taftanaz military airport, a long-contested area in the province of Idlib, activists reported. Rebels have also stepped up attacks on airports in the neighboring province of Aleppo, trying to disrupt the warplanes and helicopters that government forces increasingly rely on for attacks, and even for supply lines, in the north.

The United Nations study suggested that the human toll of the war was even greater than previously estimated. Two days ago, the Syrian Observatory for Human Rights, a rebel group that tracks the war from Britain, reported 45,000 deaths, mostly civilian, since the conflict began in March 2011.

“The number of casualties is much higher than we expected, and is truly shocking,” the United Nations high commissioner for human rights, Navi Pillay, said in a statement after her agency released the study.

“We must not compound the existing disaster by failing to prepare for the inevitable — and very dangerous — instability that will occur when the conflict ends,” she added. To avoid repeating the experience of collapsed states like Afghanistan, Iraq and Somalia, she said, “serious planning needs to get under way immediately, not just to provide humanitarian aid to all those who need it, but to protect all Syrian citizens from extrajudicial reprisals and acts of revenge.”

The study’s surprisingly high death toll reflected only those killings in which victims had been identified by their full name, and the date and location of their death had been recorded, leaving the possibility of many more dead.

Independent researchers compiled reports of more than 147,000 killings in Syria’s conflict from seven sources, including the government. When duplicates were removed, there remained a list of 59,648 people killed between March 2011 and the end of November.

Meanwhile, John Foley, James Foley’s father, stressed that his son was an “objective journalist” and issued a plea to his captors to contact the family so that they can work for his release.

“We want Jim to come safely home, or at least we need to speak with him to know he’s O.K.,” John Foley said. “Jim is an objective journalist and we appeal for the release of Jim unharmed. To the people who have Jim, please contact us so we can work together toward his release.”

Ubuntu se mete en los celulares con un sistema operativo propio

Al igual que otras plataformas que buscan una convergencia entre el mundo móvil y la PC, Canonical confirmó el arribo de su sistema operativo Ubuntu a los dispositivos móviles. Disponible en una primera instancia como una instalación no oficial para la línea de smartphones Nexus 3, la versión de Linux utilizada en más de 20 millones busca posicionarse como una alternativa ante un mercado dominado por compañías como Apple y Google, junto a las propuestas de Microsoft con Windows Phone y Research in Motion con sus teléfonos BlackBerry.

La compañía dio un primer paso en febrero de 2012 con Ubuntu for Android , una distribución para “mejorar” el Android convencional.

La versión actual es un sistema operativo que sólo comparte con Android el uso de sus drivers (ambos están basados en Linux), pero no usa una máquina virtual Java, por lo que los 700.000 programas con las que cuenta Android no estarán disponibles directamente. Ubuntu tendrá su propia suite de aplicaciones, y permitirá la suma de nuevas que estén programadas en HTML5 o sean nativas.

Canonical también planea lanzar un teléfono de diseño propio que llegaría al mercado en 2014, pero no brindó mayores detalles sobre el fabricante involucrado. Los recientes cambios en la interfaz de Ubuntu, denominada Unity, marcaron una tendencia en la distribución hacia la interacción en pantallas sensibles al tacto, y este lanzamiento representa un primer paso de la distribución para ingresar en el mundo móvil de los smartphones y las tabletas.

Las prestaciones de una PC, en un dispositivo de bolsillo

Según Mark Shuttleworth, CEO de Canonical, en un principio esta versión de Ubuntu apunta a los entusiastas de la plataforma, pero con una rápida expansión hacia el resto de los usuarios. “Por primera vez en la historia los usuarios de los teléfonos celulares pueden tener las prestaciones completas que tiene en una PC, y tenemos una ventaja en esto”, dijo el ejecutivo.

Así lo explica Mark Shuttleworth en video, mostrando los gestos que permiten controlar Ubuntu móvil:

El concepto se asemeja a la modalidad presentada por Motorola con su teléfono Atrix , que se convertía en una PC al ser conectado en una base que servía de conexión con un monitor. A su vez, el móvil también podía ser utilizado como una notebook mediante un dispositivo denominado lapdock.

Aún no disponible para su descarga, la presentación formal de Ubuntu para teléfonos ante el público será en la feria Consumer Electronic Show de Las Vegas, en donde LA NACION estará presente para la cobertura de los primeros lanzamientos del año que realizará la industria.

En busca del podio móvil

Con los dispositivos basados en iOS y Android, varias compañías disputan ser la alternativa a las plataformas dominantes. Microsoft busca de la mano de Nokia posicionar a Windows Phone junto a fabricantes como HTC y Samsung. La compañía de Redmond también desea aprovechar la integración con Windows 8 para sacar provecho de su dominio en el mundo de las PC, un segmento en lento retroceso frente a los teléfonos inteligentes y tabletas.

En este punto, la integración entre las PC y los dispositivos móviles también forman parte de los objetivos de Apple, que replicó el exitoso modelo App Store en su línea de computadoras con Mac OS X, utilizado en el iPhone y la tableta iPad, mientras que Google mantiene su apuesta en su plataforma basada en la nube con servicios como Gmail y Drive, entre otros.

Por su parte, Research in Motion presentará su nueva plataforma BB10 , un demorado lanzamiento que tendrá lugar a fines de este mes y con el que busca recuperar el terreno perdido en los últimos años con un renovado teléfono móvil tactil basado en el sistema operativo QNX, utilizado en su tableta Playbook.

Dentro de este pelotón de contendientes también se encuentra Firefox OS , un competidor que más se asemeja a la filosofía de la plataforma de Canonical y que ofrece un sistema operativo basado en el navegador web de la fundación Mozilla. Cuenta con el apoyo de las principales operadoras de telecomunicaciones y apunta a contar con un teléfono de costo accesible para mercados emergentes.

Por su parte, un grupo de desarrolladores responsables de Meego, la plataforma utilizada por Nokia para el N9, se reunieron para presentar a Sailfish OS , un sistema operativo basado en Linux que se encuentra en una incipiente etapa de desarrollo y que planea tener también, al igual que Firefox OS y Ubuntu, un teléfono para mediados de este año.

Julianne Hough: I Was Physically Abused as a Child

By Mike Fleeman

01/02/2013 at 04:45 PM EST

When Julianne Hough was 10 years old, she lived in London, away from her parents in Utah, studying dance.

That's when the abuse began, she says.

"I was abused, mentally, physically, everything," she says in Cosmopolitan's February issue, on newsstands Jan. 8.

While attending the prestigious Italia Conti Academy of Arts, she says the adults around her took advantage of her being without parental supervision: "I was 10 years old looking like I was 28, being a very sensual dancer."

"I was a tormented little kid who had to put on this sexy façade because that was my job and my life," she adds. "But my heart was the same, and I was this innocent little girl. I wanted so much love."

The actress, now 24, says the abuse became worse "when I started hitting puberty, when I started becoming a woman and stopped being a little girl."

Her classmates included future Dancing with the Stars pros Mark Ballas and Julianne's brother Derek Hough, both also children at the time. They had formed their own pop music group when Julianne was 12 performing in the U.S. and the U.K.

Hough declines to say who abused her or provide other details.

"I'm a very forgiving person, and I don't want to hurt anybody," she says. "What's past is past."

But the painful emotions surfaced during filming of her latest movie, Safe Haven, opening Feb. 14, about a girl who survives an abusive ex-boyfriend and accepts the love of a widower, played by Josh Duhamel.

During one particularly difficult scene, she says, "I went from bawling to containing to laughing to crying again. Josh was crying. I think it was the most therapeutic moment of my life."

As for her own love life, Hough says that she and boyfriend Ryan Seacrest work to find time for each other around their busy schedules.

"We love what we do," she says. "We take pride in giving it our all, but then when we're alone, we really focus in on going to dinners and being extra-romantic and affectionate and just being there for each other."

Brain image study: Fructose may spur overeating

This is your brain on sugar — for real. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating.

After drinking a fructose beverage, the brain doesn't register the feeling of being full as it does when simple glucose is consumed, researchers found.

It's a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role. These sugars often are added to processed foods and beverages, and consumption has risen dramatically since the 1970s along with obesity. A third of U.S. children and teens and more than two-thirds of adults are obese or overweight.

All sugars are not equal — even though they contain the same amount of calories — because they are metabolized differently in the body. Table sugar is sucrose, which is half fructose, half glucose. High-fructose corn syrup is 55 percent fructose and 45 percent glucose. Some nutrition experts say this sweetener may pose special risks, but others and the industry reject that claim. And doctors say we eat too much sugar in all forms.

For the study, scientists used magnetic resonance imaging, or MRI, scans to track blood flow in the brain in 20 young, normal-weight people before and after they had drinks containing glucose or fructose in two sessions several weeks apart.

Scans showed that drinking glucose "turns off or suppresses the activity of areas of the brain that are critical for reward and desire for food," said one study leader, Yale University endocrinologist Dr. Robert Sherwin. With fructose, "we don't see those changes," he said. "As a result, the desire to eat continues — it isn't turned off."

What's convincing, said Dr. Jonathan Purnell, an endocrinologist at Oregon Health & Science University, is that the imaging results mirrored how hungry the people said they felt, as well as what earlier studies found in animals.

"It implies that fructose, at least with regards to promoting food intake and weight gain, is a bad actor compared to glucose," said Purnell. He wrote a commentary that appears with the federally funded study in Wednesday's Journal of the American Medical Association.

Researchers now are testing obese people to see if they react the same way to fructose and glucose as the normal-weight people in this study did.

What to do? Cook more at home and limit processed foods containing fructose and high-fructose corn syrup, Purnell suggested. "Try to avoid the sugar-sweetened beverages. It doesn't mean you can't ever have them," but control their size and how often they are consumed, he said.

A second study in the journal suggests that only severe obesity carries a high death risk — and that a few extra pounds might even provide a survival advantage. However, independent experts say the methods are too flawed to make those claims.

The study comes from a federal researcher who drew controversy in 2005 with a report that found thin and normal-weight people had a slightly higher risk of death than those who were overweight. Many experts criticized that work, saying the researcher — Katherine Flegal of the Centers for Disease Control and Prevention — painted a misleading picture by including smokers and people with health problems ranging from cancer to heart disease. Those people tend to weigh less and therefore make pudgy people look healthy by comparison.

Flegal's new analysis bolsters her original one, by assessing nearly 100 other studies covering almost 2.9 million people around the world. She again concludes that very obese people had the highest risk of death but that overweight people had a 6 percent lower mortality rate than thinner people. She also concludes that mildly obese people had a death risk similar to that of normal-weight people.

Critics again have focused on her methods. This time, she included people too thin to fit what some consider to be normal weight, which could have taken in people emaciated by cancer or other diseases, as well as smokers with elevated risks of heart disease and cancer.

"Some portion of those thin people are actually sick, and sick people tend to die sooner," said Donald Berry, a biostatistician at the University of Texas MD Anderson Cancer Center in Houston.

The problems created by the study's inclusion of smokers and people with pre-existing illness "cannot be ignored," said Susan Gapstur, vice president of epidemiology for the American Cancer Society.

A third critic, Dr. Walter Willett of the Harvard School of Public Health, was blunter: "This is an even greater pile of rubbish" than the 2005 study, he said. Willett and others have done research since the 2005 study that found higher death risks from being overweight or obese.

Flegal defended her work. She noted that she used standard categories for weight classes. She said statistical adjustments were made for smokers, who were included to give a more real-world sample. She also said study participants were not in hospitals or hospices, making it unlikely that large numbers of sick people skewed the results.

"We still have to learn about obesity, including how best to measure it," Flegal's boss, CDC Director Dr. Thomas Frieden, said in a written statement. "However, it's clear that being obese is not healthy - it increases the risk of diabetes, heart disease, cancer, and many other health problems. Small, sustainable increases in physical activity and improvements in nutrition can lead to significant health improvements."
