Rivals pass on criticizing Gingrich's marital woes

(AP) ? Newt Gingrich's Republican rivals are not eager to criticize him on his marital woes.

Gingrich's ex-wife says in an interview with ABC News that the former House speaker asked her for an open marriage.

In a nationally televised debate Thursday night, Mitt Romney, Rick Santorum and Ron Paul were asked whether Gingrich's past infidelity is relevant to the campaign.

Romney says it's time to get on to the real issues.

Santorum says the U.S. is a forgiving country and that no one is perfect. He adds that it's up to voters in South Carolina to decide if the matter is relevant.

Paul says the attacks on Gingrich are being generated by the media. But he adds that he's proud his wife of 54 years is with him.

Taylor Swift and Zac Efron: Spotted! Giggling!


Might we soon need to Tac a new young power couple in Hollywood on to the board?

According to the latest issue of Us Weekly, Taylor Swift and Zac Efron (aka Tac, according to certain opening sentences) dined together at an Italian restaurant in Los Angeles.

Witnesses say the superstar singer and former High School Musical star "were deep in conversation and very giggly," even arriving together in the latter's Audi.

A source shoots down dating rumors between this pair, simply saying Taylor and Zac "were in L.A. doing press stuff together, and after they were done, they decided to grab dinner."

And, yes, it is true that they are starring in The Lorax together. But what fun is that? Two professionals exchanging career-oriented talk and mere friendly banter?

It's far more enjoyable to play this out in our minds and imagine Swift penning her next heartbreaking album about Efron, isn't it?

Pakistan crisis: PM faces top court in contempt case

Pakistan's prime minister made a rare appearance before the Supreme Court Thursday in attempt to avoid being held in contempt for refusing to reopen an old corruption case against the president.

Prime Minister Yousuf Raza Gilani told the court that he believes the president cannot being prosecuted because he enjoys immunity while in office.

The court launched contempt proceedings against Gilani earlier in the week for failing to obey a long-standing order to write a letter to Swiss authorities asking them to reopen a graft case against President Asif Ali Zardari dating back to the late 1990s.

"It is my conviction that he (Zardari) has complete immunity inside and outside the country," Gilani told the court. "In the constitution, there is complete immunity for the president. There is no doubt about that."

The immediate battle is about Gilani, but the larger political crisis is about Zardari and the fate of his government, the longest-running civilian administration in Pakistan's coup-marred history.

If Gilani is charged with contempt of court for failing to follow court orders, he could be disqualified from office and forced to resign.

That would further increase the pressure on the unpopular civilian government and the risk of instability in the nuclear-armed ally in America's war on militancy.

Thursday's adjournment did nothing to settle the issue, and was mainly to allow Gilani to explain his position.

After the hearing, a confident-looking Gilani appeared outside the court smiling and waving.

If found in contempt, Gilani could face up to six months in prison and be disqualified from holding office.

The court will resume hearing the case against Gilani on Feb. 1.

Gilani's legal troubles are the latest blow for the civilian administration which also faces pressure from the military over a mysterious memo seeking U.S. help to avert an alleged coup last year.

Gilani won a unanimous vote of confidence in parliament when he became prime minister nearly four years ago, and has been known as a peacemaker even among the ruling Pakistan People's Party's most bitter enemies. Unlike Zardari, he was seen as having smooth ties with the military before the latest turmoil.

But his diplomatic skills may not be enough to fend off both the Supreme Court and Pakistan's generals, who have ruled the country for more than half of its 64 years history through coups, and from behind the scenes.

"The fact is that it's not just the anger of the judges against the PM, it's the anger of the army against the PM as well," said Ayesha Siddiqa, a prominent defense analyst.

Paleozoic predator predates the dinosaurs

Voltaire Neto

The mammal-like creature known as Pampophoneus biccai takes on a plant-eating Paleozoic creature called a pareiasaur in this artist's conception.

By Alan Boyle

Paleontologists have found the skull of a weird but deadly mammal-like?monster that terrorized Brazil long before dinosaurs ruled the earth.

The specimen is from the Permian period, more than 260 million years ago. The complete skull measures about 13 inches (35 centimeters) in length and was?discovered in 2008 during a scientific excavation on a farm in the pampas region of Rio Grande do Sul in southern Brazil. The skull came from a creature that was part of a class of long-extinct?vertebrates called dinocephalian therapsids, which predated the dinosaurs and were distantly related to mammals.


In an interview with Discovery News, lead researcher Juan Carlos Cisneros of Brazil's?Federal University of?Piaui said the critter was a cross between "a tiger and a Komodo dragon, if you can imagine that." A report about the fossil was published?online today in the Proceedings of the National Academy of Sciences.

The creature has been dubbed Pampaphoneus biccai: The Latin-derived genus name roughly translates as "pampas killer," and the species name pays tribute to Jose Bicca, the landlord?of the farm where the skull was found. The fossil site was identified through an analysis of satellite imagery from Google Earth.

Juan Carlos Cisneros

A photo and a drawing show the skull discovered on a Brazilian farm.

Cisneros told me in an emailed statement that the find is important for two reasons: First,?Pampaphoneus is?the first Paleozoic terrestrial carnivore discovered in South America. Combining this find with earlier discoveries of plant-eaters from the same time frame will help paleontologists "picture a more complete ecosystem during the Permian period," the statement said.

Second, the skull suggests that this South American species was a close relative to similar dinocephalians previously found in Russia and South Africa. That supports the idea that?therapsids were able to disperse easily from one part of the Pangaea supercontinent to the other, during an age?when most of?Earth's modern-day land masses were linked together.

The therapsids were dealt a heavy blow 250 million years ago?in?an extinction event known as the "Great Dying." During the Triassic period?that followed, they gave way to the dinosaurs ??but their distant?relatives?in the mammalian tribe once again rule the earth.

Update for 7:51 p.m. ET: Brian Switek adds to the Permian picture in his Wired Science posting on the "Terrible Heads."

More about the days before the dinosaurs:


In addition to Cisneros, the authors of "Carnivorous Dinocephalian from the Middle Permian of Brazil and Tetrapod Dispersal in Pangaea" include Fernando Abdala, Saniye Atayman-G?ven, Bruce Rubidge, A.M. Sel?l Seng?r and Cesar Schultz.

Pakistani court clashes with weakened government (AP)

ISLAMABAD ? The political crisis engulfing Pakistan deepened Monday when the nation's top court clashed with a beleaguered government already under attack from the powerful army ? a combined assault that could bring down the U.S.-backed administration.

The Supreme Court launched contempt proceedings against Prime Minister Yousuf Raza Gilani for failing to carry out its order to reopen a corruption case against President Asif Ali Zardari and demanded Gilani make a rare appearance before the judges Thursday. If the court convicts Gilani of contempt, he could serve up to six months in prison and be disqualified from holding office.

The nuclear-armed country is already grappling with an ailing economy and a violent Islamist insurgency. The latest clash could also complicate U.S. efforts to get Pakistan to cooperate on the war in neighboring Afghanistan, especially peace talks with the Taliban ? although Washington had made little headway on that even before this crisis.

"The Supreme Court and the government are in an open clash now, and it seems fairly obvious the court is unwilling to back off," said Cyril Almeida, a lawyer and columnist for Pakistan's Dawn newspaper.

Even before the latest clash with the court, the government was locked in a bitter conflict with the army over a secret memo sent to Washington last year aimed at stopping a supposed military coup.

The Supreme Court ruling boosted the sense that the administration could fall, squeezed between the court and Pakistan's powerful generals. Some observers have speculated the army is working behind the scenes with the court to oust the government by constitutional means.

"Once the Supreme Court, the army and the political opposition agree the government needs to go sooner rather than later, it seems very difficult for the government to stay on," Almeida said.

Still the court could have its own reasons for stepping up pressure on the government. Supreme Court Justice Mohammad Iftikhar Chaudhry has clashed with Zardari in the past, and the judges could be fed up with the government defying its order to reopen the corruption case against the president.

Gilani promised to appear before the Supreme Court on Thursday but warned both the judges and the army that they must protect democracy.

"It cannot happen that they derail system," said Gilani after a majority in parliament ? mostly the ruling party and its allies ? passed a resolution supporting the government.

The resolution said the balance of powers "must be fully respected and adhered to and all state institutions must strictly function within the limits imposed on them by the constitution."

Critics have predicted the civilian government's demise many times since it was elected in 2008 after 10 years of military rule, and it has always defied the forecasts. But this time around, the crisis has drawn the army in more directly, and the court seems to be in no mood to compromise

Since Pakistan was founded in 1947, no civilian government has ever completed a full five-year term before being toppled by a military coup or forced to call early elections. There have been three coups over that period, and while a fourth is considered unlikely, early polls look increasingly possible because of the rising tension.

The Supreme Court has ordered the government to ask Swiss authorities to reopen a corruption case against the president that dates back to the 1990s. The case centers on $60 million in kickbacks that Zardari and his late wife, former Prime Minister Benazir Bhutto, allegedly received from Swiss cargo companies.

The government has refused to reopen the case, saying Zardari has immunity, and supporters say the court is pursuing a vendetta against the civilian leadership.

Zardari has been vulnerable to prosecution since 2009 when the Supreme Court struck down an amnesty granting him and other leading political figures immunity from past graft cases. The court deemed the amnesty, which was granted in 2008, as unconstitutional.

The court initiated contempt proceedings against the prime minister on Monday after the government failed to respond to an order outlining a series of punitive options the judges could take if the government did not reopen the case against Zardari. Attorney General Maulvi Anwarul Haq told the court he had not received instructions from the country's leaders on how to respond to the order ? a response that clearly angered the judges.

Faced with going to jail, Gilani may tell the court during his appearance Thursday that he intends to write the letter to Swiss authorities authorizing them to reopen the case against Zardari, but that could come with a serious political cost.

Zardari stated in an interview last week that he would never send the letter, saying it would dishonor his late wife. Last year, Swiss prosecutors told reporters they couldn't reopen the case because Zardari had immunity.

The prime minister has also clashed with army ? the strongest institution in the country ? over the memo scandal.

The army was outraged by the memo, which was allegedly sent by the government and offered the U.S. a raft of favorable security policies in exchange for reining in the military.

The army pushed the Supreme Court to open an inquiry into the scandal last month against the wishes of the government, which has denied any connection to the memo and argued the matter was already being probed by parliament.

Gilani criticized the army last week for cooperating with the Supreme Court probe, saying the standoff was nothing less than a choice between "democracy and dictatorship." The prime minister's comments followed a warning from the generals of possible "grievous consequences" ahead if the government did not stop its criticism of the army.

Gilani warned members of parliament Thursday, especially in the opposition, of serious consequences if they didn't stand by the government in supporting democracy.

"If there is no democracy, everything will be finished," said Gilani. "If there is no democracy, we will all go together."

Asia stocks rise, focus on China monetary policy

BANGKOK (AP) ? Asian stock markets rose, focused on expectations that China will loosen its monetary policy to boost growth. But European shares slid in early trading as the continent's debt crisis once again moved to the forefront.

Benchmark oil hovered near $101 per barrel while the dollar fell against the euro and the yen.

Britain's FTSE 100 fell 0.6 percent to 5,662.19. Germany's DAX slipped 0.5 percent to 6,304.31 and France's CAC-40 shed 0.6 percent to 3,250.74. On Wall Street, Dow Jones industrial futures fell 0.1 percent to 12,403 while S&P 500 futures lost 0.2 percent at 1,287.40.

Investor were jittery over Greece, which is running out of time to avoid becoming the first country that uses the euro to default on its debts and potentially trigger a chain reaction that could ultimately destabilize the global economy.

Athens was to resume negotiations later Wednesday with the Institute of International Finance, which represents bondholders. Talks stalled on Friday after disagreement erupted over the terms of new bonds that Greece would issue to replace expiring bonds that it cannot afford to pay off.

Asian stocks fared better amid confidence in the Chinese economy.

Japan's Nikkei 225 index rose 1 percent to close at 8,550.58. Hong Kong's Hang Seng added 0.3 percent to 19,686.92. South Korea's Kospi was nearly unchanged at 1,892.39, while Australia's S&P/ASX 200 was up slightly at 4,217.90. Benchmarks in Taiwan, Indonesia and Malaysia also rose.

Mainland Chinese shares fell on profit-taking after a brisk day of trade Tuesday that saw the biggest gains in 27 months. The Shanghai Composite Index lost 1.4 percent to 2,266.38, while the Shenzhen Composite Index dropped 2.7 percent to 837.40.

Investors cheered news out of China on Tuesday when the government said its economy slowed less dramatically in the fourth quarter than feared ? but still enough of a slowdown to persuade investors that Beijing will pursue a pro-growth monetary policy, analysts said.

"People have been buying stocks in anticipation of a relaxation in monetary policy by the Chinese government," said Derek Cheung, chief investment officer at Neutron INV Partners Ltd. in Hong Kong. "The market expects this around Chinese New Year. If China doesn't loosen around the new year, the market may come under pressure." The holiday begins Jan. 23.

China is one of the biggest importers and slower growth could have global repercussions if it cuts demand for iron ore, industrial components and other goods from Australia, Brazil, Southeast Asia and elsewhere.

It would also mean less demand for U.S. and European capital goods for Chinese factories and construction sites, and smaller profits for U.S. and European companies that do business in China. The luxury goods industry would also feel a significant pinch, since China is just about its only growth market.

Commodity shares jumped on the growth data out of China. In Australia, miners Fortescue Metals Group soared 5.2 percent and Rio Tinto Ltd. added 1.4 percent after both companies reported target-beating production figures.

But financial shares came under pressure on weak quarterly earnings from some U.S. banks, including Citigroup Inc., which said its fourth-quarter income fell 11 percent due in part to lower investment banking income and an accounting charge.

Australia & New Zealand Banking Group fell 1.2 percent and Hong Kong-listed Agricultural Bank of China lost 1.6 percent.

South Korean high-tech shares lost ground. Samsung Electronics Co., the top global manufacturer of flat screen televisions, memory chips and liquid crystal displays, fell 0.6 percent. LG Electronics shed 1.5 percent, and Hynix Semiconductor was 1.2 percent lower.

Benchmark crude for February delivery was up 8 cents to $100.79 per barrel in electronic trading on the New York Mercantile Exchange. The contract finished at $100.71 per barrel in New York on Tuesday.

In currency trading, the euro rose to $1.2755 from $1.2722 late Tuesday in New York. The dollar fell to 76.68 yen from 76.82 yen.

Stomach cells may give rise to esophageal cancer

Stomach cells may give rise to esophageal cancer [ Back to EurekAlert! ] Public release date: 17-Jan-2012

A new study is providing clues that may answer a decades-old question about the cells that give rise to a particularly lethal form of esophageal cancer. The research, published by Cell Press in the January 17th issue of the journal Cancer Cell, links inflammation and bile acid reflux with migration of cancer-causing stomach cells into the esophagus and may help guide future strategies for early therapeutic intervention.

Esophageal adenocarcinoma is a cancer of the esophagus that is associated with acid reflux disease and Barrett esophagus (BE). BE is characterized by abnormal changes in the cells that line the lower esophagus, very close to the junction with the stomach. In BE, the normal flat esophageal cells are replaced by taller cells resembling those that line the stomach or intestine. Previous research has suggested that BE may be caused by acid reflux disease and chronic inflammation, but many questions about the disease remain unanswered.

"The precise origin of both esophageal adenocarcinoma and BE has been difficult to discern, in part because of the absence of useful experimental model systems that are genetically based," explains study author Dr. Timothy C. Wang, from Columbia University. "A major unanswered question that has been debated for decades is whether BE cells originate from the lining of the esophagus itself or from the region of the stomach called the cardia that is adjacent to the esophagus."

Dr. Wang, coauthor Dr. Michael Quante from the Technical University of Munich, and colleagues used a transgenic mouse model of BE and adenocarcinoma that closely resembles human disease to explore the pathogenesis of the disease. The mice were engineered to express a specific molecule (interleukin-1) associated with chronic esophageal inflammation. The researchers discovered that inflammation and bile acid caused immature cells from the cardia to migrate to the esophagus and give rise to the taller "columnar" cells characteristic of BE. They went on to identify the specific signaling pathway that appeared to regulate differentiation of the cardia cells into columnar cells, and that was associated with the origination of cancer in mice and humans.

Taken together, the findings suggest that the abnormal cells associated with BE and esophageal adenocarcinoma actually originate in the cardia of the stomach and not the esophagus. "The fact that BE always begins precisely at the junction where the esophagus meets the stomach has never been explained, and now it seems clear that special consideration should be given to inflammation of the gastric cardia as it may represent a precursor of BE and esophageal adenocarcinoma," concludes Dr. Wang.
