In brewing rivalry, Instagram trims ties to Twitter

SAN FRANCISCO (Reuters) – Facebook Inc’s recently acquired photo-sharing service Instagram removed a key element of its integration with Twitter, signaling a deepening rift between two of the Web’s dominant social media companies.

Instagram Chief Executive Kevin Systrom said Wednesday his company turned off support for Twitter “cards” in order to drive Twitter users to Instagram’s own website. Twitter “cards” are a feature that allows multimedia content like YouTube videos and Instagram photos to be embedded and viewed directly within a Twitter message.

The move marked the latest clash between Facebook and Twitter since April, when Facebook, the world’s no. 1 social network, outbid Twitter to nab fast-growing Instagram in a cash-and-stock deal valued at the time at $ 1 billion. The acquisition closed in September for roughly $ 715 million, reflecting Facebook’s recent stock drop.

The companies’ ties have been strained since. In July, Twitter blocked Instagram from using its data to help new Instagram users find friends.

Beginning earlier this week, Twitter’s users began to complain in public messages that Instagram photos did not seem to display properly on Twitter’s website.

Systrom confirmed Wednesday that his company had decided its users should view photos on Instagram’s own Web pages and took steps to change its policies.

“We believe the best experience is for us to link back to where the content lives,” Systrom said in a statement, citing recent improvements to Instagram’s website.

“A handful of months ago, we supported Twitter cards because we had a minimal Web presence,” Systrom said, noting that the company has since released new features that allow users to comment about and “like” photos directly on Instagram’s website.

The move escalates a rivalry in the fast-growing social networking sector, where the biggest players have sought to wall off access to content from rival services and to their ranks of users.

“They’re both competing for slices of the same pie, the pie being users’ attention,” said Ray Valdes, an analyst with research firm Gartner.

If Facebook decides to offer advertising on Instagram, it’s important that the users visit Instagram’s own website, said Valdes. “If the eyeballs are elsewhere, you have less to work with in terms of monetization,” he said.

Photos are among the most popular features on both Facebook and Twitter, and Instagram’s meteoric rise in recent years has further proved how picture-sharing has become a key front in the battle for social Internet supremacy.

Instagram, which has 100 million users, allows consumers to tweak the photos they take on their smartphones and share the images with friends, a feature that Twitter has reportedly also begun to develop. Twitter’s executive chairman, Jack Dorsey, was an early investor in Instagram and had hoped to acquire it before Facebook CEO Mark Zuckerberg made a successful bid.

When Zuckerberg announced the acquisition in an April blog post, he highlighted Instagram’s inter-connectivity with other social networks.

“We think the fact that Instagram is connected to other services beyond Facebook is an important part of the experience,” Zuckerberg wrote. “We plan on keeping features like the ability to post to other social networks.”

A Twitter spokesman declined comment Wednesday, but a status message on Twitter’s website confirmed that users are “experiencing issues,” such as “cropped images” when viewing Instagram photos on Twitter.

Alpha /Landov; Inset:Allpix/ plash News Online

The Duchess of Cambridge had more hospital visitors on Wednesday.

Just two days after husband Prince William, 30, was photographed leaving the King Edward VII Hospital in Central London where a pregnant Kate, 30, was admitted for hyperemesis gravidarum, her sister, Pippa Middleton, brother James and mom Carole (not pictured), also dropped by to keep the mom-to-be company.

Pippa was bundled up in a coat, sporting a tan-colored ensemble, while her brother was casually dressed in jeans and layered tops.

The Palace announced the Duchess's pregnancy Monday in a statement. "Their Royal Highnesses The Duke and Duchess of Cambridge are very pleased to announce that The Duchess of Cambridge is expecting a baby," it said. "The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall and Prince Harry and members of both families are delighted with the news."

Study could spur wider use of prenatal gene tests

A new study sets the stage for wider use of gene testing in early pregnancy. Scanning the genes of a fetus reveals far more about potential health risks than current prenatal testing does, say researchers who compared both methods in thousands of pregnancies nationwide.

A surprisingly high number — 6 percent — of certain fetuses declared normal by conventional testing were found to have genetic abnormalities by gene scans, the study found. The gene flaws can cause anything from minor defects such as a club foot to more serious ones such as mental retardation, heart problems and fatal diseases.

"This isn't done just so people can terminate pregnancies," because many choose to continue them even if a problem is found, said Dr. Ronald Wapner, reproductive genetics chief at Columbia University Medical Center in New York. "We're better able to give lots and lots of women more information about what's causing the problem and what the prognosis is and what special care their child might need."

He led the federally funded study, published in Thursday's New England Journal of Medicine.

A second study in the journal found that gene testing could reveal the cause of most stillbirths, many of which remain a mystery now. That gives key information to couples agonizing over whether to try again.

The prenatal study of 4,400 women has long been awaited in the field, and could make gene testing a standard of care in cases where initial screening with an ultrasound exam suggests a structural defect in how the baby is developing, said Dr. Susan Klugman, director of reproductive genetics at New York's Montefiore Medical Center, which enrolled 300 women into the study.

"We can never guarantee the perfect baby but if they want everything done, this is a test that can tell a lot more," she said.

Many pregnant women are offered screening with an ultrasound exam or a blood test that can flag some common abnormalities such as Down syndrome, but these are not conclusive.

The next step is diagnostic testing on cells from the fetus obtained through amniocentesis, which is like a needle biopsy through the belly, or chorionic villus sampling, which snips a bit of the placenta. Doctors look at the sample under a microscope for breaks or extra copies of chromosomes that cause a dozen or so abnormalities.

The new study compared this eyeball method to scanning with gene chips that can spot hundreds of abnormalities and far smaller defects than what can be seen with a microscope. This costs $1,200 to $1,800 versus $600 to $1,000 for the visual exam.

In the study, both methods were used on fetal samples from 4,400 women around the country. Half of the moms were at higher risk because they were over 35. One-fifth had screening tests suggesting Down syndrome. One-fourth had ultrasounds suggesting structural abnormalities. Others sought screening for other reasons.

"Some did it for anxiety — they just wanted more information about their child," Wapner said.

Of women whose ultrasounds showed a possible structural defect but whose fetuses were called normal by the visual chromosome exam, gene testing found problems in 6 percent — one out of 17.

"That's a lot. That's huge," Klugman said.

Gene tests also found abnormalities in nearly 2 percent of cases where the mom was older or ultrasounds suggested a problem other than a structural defect.

Dr. Lorraine Dugoff, a University of Pennsylvania high-risk pregnancy specialist, wrote in an editorial in the journal that gene testing should become the standard of care when a structural problem is suggested by ultrasound. But its value may be incremental in other cases and offset by the 1.5 percent of cases where a gene abnormality of unknown significance is found.

In those cases, "a lot of couples might not be happy that they ordered that test" because it can't give a clear answer, she said.

Ana Zeletz, a former pediatric nurse from Hoboken, N.J., had one of those results during the study. An ultrasound suggested possible Down syndrome; gene testing ruled that out but showed an abnormality that could indicate kidney problems — or nothing.

"They give you this list of all the things that could possibly be wrong," Zeletz said. Her daughter, Jillian, now 2, had some urinary and kidney abnormalities that seem to have resolved, and has low muscle tone that caused her to start walking later than usual.

"I am very glad about it," she said of the testing, because she knows to watch her daughter for possible complications like gout. Without the testing, "we wouldn't know anything, we wouldn't know to watch for things that might come up," she said.

The other study involved 532 stillbirths — deaths of a fetus in the womb before delivery. Gene testing revealed the cause in 87 percent of cases versus 70 percent of cases analyzed by the visual chromosome inspection method. It also gave more information on specific genetic abnormalities that couples could use to estimate the odds that future pregnancies would bring those risks.

The study was led by Dr. Uma Reddy of the National Institute of Child Health and Human Development.

Wall Street slips as investors seek cliff progress

NEW YORK (Reuters) - Stocks finished slightly lower in a quiet session on Tuesday as the back-and-forth wrangling over the "fiscal cliff" gave investors little reason to act.

Trading volume was light as legislators continue to negotiate a deal to avoid a $600 billion package of tax hikes and federal spending cuts that would begin January 1 and could push the economy into recession.

Just 5.86 billion shares changed hands on the New York Stock Exchange, the Nasdaq and the NYSE MKT, below the year's daily average of 6.48 billion shares.

A key measure of investor anxiety has remained muted. The CBOE Volatility Index or VIX <.vix>, a gauge of market anxiety, was at 17.12, up 2.9 percent. It has not traded above 20 since July.

Optimism for progress was dented after remarks by President Barack Obama, who rejected a Republican proposal to resolve the crisis as "out of balance" and said any deal must include a rise in income tax rates on the wealthiest Americans.

"People don't know if what's going on is political posturing or real negotiations that represent progress," said Bernard Baumohl, managing director and chief global economist at the Economic Outlook Group in Princeton, New Jersey.

Expectations of higher taxes on dividends beginning in 2013 have pushed many companies to pay special dividends this year or advance their next payback to investors. Coach became the latest to move up the date of its next dividend payment, and the news lifted shares of the upscale leather-goods maker earlier in the session. By the close, though, Coach was down 1.2 percent at $57.52.

One of the S&P 500's top sectors for the day was health care <.gspa>, considered a defensive group.

The Dow Jones industrial average <.dji> fell 13.82 points, or 0.11 percent, to 12,951.78 at the close. The Standard & Poor's 500 Index <.spx> dipped 2.41 points, or 0.17 percent, to 1,407.05. The Nasdaq Composite Index <.ixic> shed 5.51 points, or 0.18 percent, to close at 2,996.69.

The market has been sensitive to rhetoric from Washington, as a failure to reach an agreement could send the U.S. economy back into recession. Still, many expect a resolution to be found, which could extend the S&P 500's rally of 12 percent so far this year.

Differences within the Republican Party came to the fore on Tuesday as one senator opposed to raising taxes lashed out at Republican House Speaker John Boehner for proposing to increase revenue by closing some tax loopholes.

Congressional Republicans recently proposed steep spending cuts to bring down the budget deficit, but gave no ground on Obama's call to raise tax rates on the rich. The proposal was quickly dismissed by the White House.

"We're on hold trying to figure it out, but investors are stressed since they have to make decisions soon about how to proceed with their investments if taxes are indeed going up. We could see a real pick-up in volume over the next week or so," Baumohl said.

Netflix Inc was the S&P 500's top percentage gainer, advancing 14 percent to $86.65 after Walt Disney Co agreed to give the company exclusive TV distribution rights to its movies, starting in 2016.

Intel Corp shares rose 2.2 percent to $19.97 after the top chipmaker sold $6 billion in bonds to fund stock buybacks and other business activities.

Darden Restaurants Inc shares plunged 9.6 percent to $47.40 as the S&P 500's worst performer after the company warned that its latest quarter would miss expectations after unsuccessful promotions led to a decline in sales at its Olive Garden, Red Lobster and LongHorn Steakhouse chains.

In contrast, Big Lots Inc surged 11.5 percent to $31.27 after the close-out retailer posted a smaller-than-expected loss and boosted its full-year adjusted earnings forecast.

MetroPCS Communications shares tumbled 7.5 percent to $9.96 after Sprint Nextel appeared unlikely to make a counter-offer for the wireless service provider.

Almost half of the stocks traded on the New York Stock Exchange closed lower, while 50 percent of Nasdaq-listed shares closed in negative territory.

After the closing bell, Pandora Media Inc

shares plunged 23 percent after the company reported its third-quarter results.

Dispute Flares Over Energy Exploration in South China Sea

BEIJING — China and two of its neighbors, Vietnam and India, were locked in a new dispute on Tuesday over energy exploration in the South China Sea, a signal that Beijing plans to continue its hard line in the increasingly contentious waterway.

Vietnam accused a Chinese fishing boat of cutting a seismic cable attached to one of its vessels exploring for oil and gas near the Gulf of Tonkin, an act apparently intended to inhibit Vietnam from pursuing energy deposits.

Vietnam said Tuesday that in retaliation, it would send out new patrols, which would include the marine police, to guard against increasing encroachment by Chinese fishing boats in the South China Sea. India, which operates several joint ventures with Vietnam’s national energy company, Petro Vietnam, said it would consider sending navy vessels to protect its interests in the South China Sea.

The latest episode followed an announcement by Hainan Province in southern China last week that Chinese vessels would board and search ships in contested areas of the waterway, which includes vital shipping lanes through which more than a third of global trade moves.

The new tensions among China, Vietnam and India illustrate in stark terms the competition in the South China Sea for what are believed to be sizable deposits of oil and gas.

Some energy experts in China see the sea as an important new energy frontier close to home that could make China less dependent on its huge oil imports from the Middle East.

On Monday, China’s National Energy Administration named the South China Sea as the main offshore site for natural gas production. Within two years, China aims to produce 150 billion cubic meters of natural gas from fields in the sea, a significant increase from the 20 billion cubic meters produced so far, the agency said.

Earlier this year, China’s third-largest energy company, the state-owned China National Offshore Oil Corporation, began drilling with a rig in deep water in nondisputed waters off the southern coast of China.

The escalation in the South China Sea comes less than a month after Xi Jinping took office as China’s leader. Mr. Xi appears to have taken a particular interest in the South China Sea and the serious dispute between China and Japan over the islands known as Diaoyu in China and as Senkaku in Japan. Whether any of China’s most recent actions in the South China Sea were associated with Mr. Xi was not clear.

But Mr. Xi does lead a small group of policy makers clustered in the Maritime Rights Office, which serves to coordinate agencies within China, according to Zhu Feng, a professor of international relations at Peking University, and other Chinese experts. The unit is part of the office of the Foreign Affairs Leading Small Group, Mr. Zhu said. The leading small group, now headed by Mr. Xi, is widely believed to be China’s central policy-making group.

China’s Foreign Ministry reiterated on Tuesday that China opposed oil and gas development by other countries in disputed waters of the sea. China maintains that it has “undisputed” sovereignty over the South China Sea, and that only China is allowed to develop the energy resources.

“We hope that concerned countries respect China’s position and rights,” said the Foreign Ministry spokesman, Hong Lei.

Vietnam, which has long been wary of China but enjoys a relationship through its governing Communist Party, summoned the Chinese ambassador on Monday to protest the cutting of the seismic cable, the Vietnamese news media reported.

A Web site run by Petro Vietnam, the oil company, reported that the company’s exploration vessel Binh Minh 02 had its seismic cable severed by a Chinese fishing vessel on Friday. In May 2011, the Vietnamese authorities said a similar cable of the Binh Minh 02 was cut by three Chinese surveillance ships, resulting in weeks of anti-China protests in Hanoi.

In its decree on the new patrols, Vietnam said that civilian ships, supported by the marine police and a border force, would be deployed starting next month to stop foreign vessels that violate fishing laws in waters claimed by Vietnam.

A senior official of Petro Vietnam, Pham Viet Dung, was quoted in the Vietnamese news media as saying that large numbers of Chinese fishing boats, many of them substantial vessels, had recently entered waters claimed by Vietnam. The fishing vessels interfered with the operations of the oil company, he said.

India, whose state-run oil company, the Oil and Natural Gas Corporation, has a 45 percent interest in exploration with Petro Vietnam, also reacted strongly.

The head of the Indian Navy, Adm. D. K. Joshi, said that India was prepared to send navy vessels to protect its interests in the sea. “Now, are we preparing for it? Are we having exercises of that nature? The short answer is ‘yes,’ ” Admiral Joshi told reporters in India.

The most recent moves by China in the South China Sea have not won total support at home. Mr. Zhu, the professor, said he did not believe that China had become more assertive in the South China Sea.

But, he said, “the cable cutting is really unfriendly.”

Bree Feng contributed reporting.

Study: Drug coverage to vary under health law

WASHINGTON (AP) — A new study says basic prescription drug coverage could vary dramatically from state to state under President Barack Obama's health care overhaul.

That's because states get to set benefits for private health plans that will be offered starting in 2014 through new insurance exchanges.

The study out Tuesday from the market analysis firm Avalere Health found that some states will require coverage of virtually all FDA-approved drugs, while others will only require coverage of about half of medications.

Consumers will still have access to essential medications, but some may not have as much choice.

Connecticut, Virginia and Arizona will be among the states with the most generous coverage, while California, Minnesota and North Carolina will be among states with the most limited.

Wall Street sours on weak domestic factory data

NEW YORK (Reuters) - Stocks struggled to extend the previous week's gains, dropping on Monday as disappointing U.S. factory numbers dampened optimism about China's economic growth.

The declines broke a three-day streak of gains for the S&P 500, keeping it shy of its 50-day moving average of about 1,420, a level that the index has been below since October 22, and now serving as a key resistance point for investors.

Manufacturing activity in the United States surprisingly contracted in November, the Institute for Supply Management said, dropping to its lowest level in more than three years. Economic data has been mixed in recent months, fanning worries about the pace of growth at a time when investors are already concerned about the "fiscal cliff" issue in Washington.

The ISM number "was below expectations that were already conservative, and that puts an exclamation point on the concern many of us have about the cliff's impact on the economy," said Leo Grohowski, chief investment officer at BNY Mellon Wealth Management in New York.

Markets had opened higher as output by China's factories grew in November for the first time in more than a year, data showed. Investors look to strength from China, the world's second-largest economy, to offset weak growth in the United States and Europe.

Still, the fiscal cliff remains investors' primary focus, with political haggling continuing over how to deal with large automatic spending cuts and tax hikes scheduled to kick in next year. The worry is that the combination of reduced spending and higher taxes could tip the U.S. economy back into recession.

While off its highs for the year, the S&P 500 is still up 12.1 percent for 2012.

"This could be the last opportunity for investors to take profits" after an unexpectedly strong year, said Grohowski, who helps oversee about $170 billion in assets.

Materials were the weakest sector on Monday, led lower by Newmont Mining after the company said its CEO resigned. Newmont's stock fell 3 percent to $45.69. Dow component DuPont dropped 1.7 percent to $42.39. An S&P materials index <.gspm> lost 1.8 percent.

The Dow Jones industrial average <.dji> fell 59.98 points, or 0.46 percent, to 12,965.60 at the close. The Standard & Poor's 500 Index <.spx> declined 6.72 points, or 0.47 percent, to 1,409.46. The Nasdaq Composite Index <.ixic> dropped 8.04 points, or 0.27 percent, to end at 3,002.20.

U.S. Treasury Secretary Timothy Geithner pushed Republicans on Sunday to offer specific ideas to cut the deficit. He predicted that they would agree to raise tax rates on the rich to obtain a year-end deal to avoid the fiscal cliff.

Among other factors serving to offset the ISM report on U.S. factories were two developments in the euro zone: Spain formally requested the disbursement of more than $50 billion of European funds to recapitalize its crippled banking sector, while Greece said it would spend 10 billion euros ($13 billion) to buy back bonds in a bid to reduce its ballooning debt.

The PHLX Europe sector index <.xex> added 0.1 percent.

Dell shares gained 4.4 percent to $10.06. The stock was one of the biggest percentage gainers in both the S&P 500 and Nasdaq 100 <.ndx> after Goldman Sachs upgraded the stock to "buy" from "sell.

Advanced Micro Devices was the S&P's top gainer, rising 7.3 percent to $2.36. Options traders appeared to be betting on further gains ahead. Early options order flow was focused on upside April calls, including a sweep of 3,594 April $3.50 strike calls for 16 cents per contract when the market was 14 cents to 16 cents, said WhatsTrading.com options strategist Frederic Ruffy.

Retail stocks were among the weakest of the day, with J.C. Penney Co off 3.2 percent at $17.36 and Staples Inc off 2.3 percent at $11.43. Consumer discretionary names tend to underperform during periods of economic uncertainty as consumers focus on core purchases.

Volume was light, with about 5.58 billion shares traded on the New York Stock Exchange, the Nasdaq and the NYSE MKT, well below last year's daily average of 7.84 billion.

Decliners outnumbered advancers on the NYSE by a ratio of 3 to 2, while on the Nasdaq, about 14 stocks fell for every 11 that rose.

Syrian Government Beset by Battles and Diplomatic Setbacks

Narciso Contreras/Associated Press

A kitchen in a residence in Aleppo, Syria, damaged Sunday in fighting between Free Syrian Army fighters and government forces.

BEIRUT, Lebanon — Fierce fighting on the battlefield and setbacks on the diplomatic front increased pressure on the embattled Syrian government on Monday as fresh signs emerged of a worsening battle for control of the capital.

A senior Turkish official said that Russia had agreed on Monday to a new diplomatic approach that would seek ways to persuade President Bashar al-Assad to relinquish power, a possible weakening in Russia’s steadfast support for the government. Fighting raged around Damascus, the Syrian capital, and its airport, disrupting commercial flights for a fourth straight day.

A prominent Foreign Ministry spokesman was said to have left the country amid reports of his defection, and both President Obama and Secretary of State Hillary Rodham Clinton issued warnings that any use of chemical weapons by a desperate government would be met with a strong international response. A Western diplomat confirmed that there were grave concerns in United States intelligence circles that Syrian leaders could resort to the use of the weapons as their position deteriorates.

The Syrian Foreign Ministry, repeating earlier statements, told state television that the government “would not use chemical weapons, if it had them, against its own people under any circumstances.”

The United Nations said it was withdrawing nonessential international staff from Syria, and the European Union said it was reducing activities in Damascus “to a minimum,” as security forces pummeled the suburbs with artillery and airstrikes in a struggle to seal off the city from its restive outskirts and control the airport road. A senior Russian official spoke for the first time in detail about the possibility of evacuating Russian citizens.

Mr. Assad has held on longer than many had predicted at the start of the 21-month uprising. He still has a strong military advantage and undiminished support from his closest ally, Iran. Military analysts doubt the rebels are capable of taking Damascus by force, and one fighter interviewed on Monday said the government counteroffensive was inflicting heavy losses. There were still no firm indications from Russia that it was ready to join Turkey and Western nations in insisting on Mr. Assad’s immediate departure.

But the latest grim developments follow a week of events that suggested the Assad government was being forced to fight harder to keep its grip on power. Rebels threatened its vital control of the skies, using surface-to-air missiles to down a fighter plane and other aircraft. The opposition also gained control of strategic military bases and their arsenals, and forced the government to shut down the Damascus airport periodically. The Internet was off for two days.

A Russian political analyst with contacts at the Foreign Ministry said that “people sent by the Russian leadership” who had contact with Mr. Assad two weeks ago described a man who has lost all hope of victory or escape.

“His mood is that he will be killed anyway,” Fyodor Lukyanov, editor of a Russian foreign affairs journal and the head of an influential policy group, said in an interview in Moscow, adding that only an “extremely bold” diplomatic proposal could possibly convince Mr. Assad that he could leave power and survive.

“If he will try to go, to leave, to exit, he will be killed by his own people,” Mr. Lukyanov said, speculating that security forces dominated by Mr. Assad’s minority Alawite sect would not let him depart and leave them to face revenge. “If he stays, he will be killed by his opponents. He is in a trap. It is not about Russia or anybody else. It is about his physical survival.”

Many observers — United Nations personnel in Syria, Arab diplomats and opposition activists — stress that it is difficult to reliably assess the state of the government. But taken together, the day’s events suggested that the government’s position was declining more sharply than it had in months and that an international scramble to find a solution to the crisis was intensifying.

Nabil al-Araby, the head of the Arab League, said on Monday that the government could fall at “any time,” Agence France-Presse reported.

“I think there will be something soon,” he said. “Facts on the ground indicate very clearly now that the Syrian opposition is gaining, politically and militarily.”

The Arab League has long called for Mr. Assad to step down. But Russia, Mr. Assad’s most powerful ally, has held out the possibility of his staying in power during a transition, so the Russian government’s apparent shift of emphasis carried more weight.

Anne Barnard reported from Beirut, Lebanon, and Ellen Barry from Moscow. Reporting was contributed by Sebnem Arsu in Istanbul, Peter Baker in Washington, Hwaida Saad, Neil MacFarquhar and Hania Mourtada in Beirut and Christine Hauser in New York.
