Troops, tanks patrol in northeast Nigeria (Reuters)

MAIDUGURI, Nigeria (Reuters) ? Heavily armed troops and tanks patrolled the streets of Maiduguri in northeast Nigeria Sunday, witnesses said, after the president declared a state of emergency in parts of the north affected by an Islamist insurgency.

President Goodluck Jonathan imposed the state of emergency on the northeast, the conflict-prone central city of Jos, and part of Niger state near Abuja Saturday, and closed the borders with Cameroon, Chad and Niger in the northeast.

Nearly a week after the radical sect Boko Haram set off a series of bombs across Nigeria on Christmas Day, including one at a church that killed at least 37 people and wounded 57, Jonathan told state television his aim was to restore security in troubled parts of the north.

A Reuters reporter in Maiduguri, a remote city in the northeast and the center of the Boko Haram insurgency, saw several tanks patrolling the city and groups of a dozen or more soldiers at a time out on foot patrol.

"We woke up this morning only to see armed soldiers all over the place and some tanks patrolling. We fear what may happen next," said Maiduguri resident Buba Guduf.

Jonathan said he had told his chief of defense staff to take other "appropriate" measures, including setting up a special counter-terrorism force.

The blasts at churches have raised fears that Boko Haram, a movement styled on the Taliban, is trying to ignite sectarian strife in Nigeria, Africa's most populous nation and top oil producer.

Jonathan has been criticized by the opposition and Christian groups for what they said was a slow response to the bombings.

CLASHES FEARED

Residents of Maiduguri, located on the threshold of the Sahara Desert, have borne the brunt of previous clashes between Boko Haram, whose name means "Western education is forbidden," and security forces.

Friday three explosions struck Maiduguri shortly after Muslim prayers but caused no casualties, and gunmen shot dead three members of a Muslim cleric's family.

Gun battles between security forces and Boko Haram killed at least 68 people in two days of fighting in the nearby city of Damaturu on December 22 and 23.

"The soldiers have intensified their patrol in our area and most people prefer to remain indoors for fear of the unknown," Ibrahim Usman, from the Gwange ward of Maiduguri, told Reuters by telephone.

"We are just doing our normal duty," said an officer for the Joint Military Taskforce for Maiduguri, who could not be named because he was not authorized to speak.

The bomb attacks by Boko Haram have strained Nigeria's already fractious north-south divide.

Jonathan, a Christian from the south, upset many northerners by running for and winning the presidency in April, tearing up what many saw as a tacit deal to rotate the top job between a northerner and a southerner every two terms.

More than 500 people were killed in post-election violence in the north after Jonathan's victory, reflecting long-standing northern grievances about perceived alienation and exclusion by the government from the fruits of the oil wealth that is concentrated in the south.

Saturday, Jonathan visited the scene of the deadliest Christmas attack, on St. Theresa's Catholic church in Madalla, on the outskirts of Abuja.

"We will crush the terrorists," he told weeping relatives of the victims gathered in the church for a vigil.

In a separate, unrelated incident, clashes between rival ethnic groups in southeastern Ebonyi state Saturday killed at least 50 people, and police said mobile units had been sent there to quell the violence.

Those clashes are likely to add to Jonathan's woes at a time when his forces are already stretched.

Molecular mechanism links temperature with sex determination in some fish species

ScienceDaily (Dec. 29, 2011) ? A study led by the CSIC's Institute of Marine Sciences, in collaboration with researchers from the Centre for Genomic Regulation (CRG), has found the epigenetic mechanism that links temperature and gonadal sex in fish. High temperature increases DNA methylation of the gonadal aromatase promoter in female.

The environmental temperature has effects on sex determination. There are species, such as the Atlantic silverside fish, whose sex determination depends mainly on temperature. And there are other species whose sex determination is written within its DNA but still temperature can override this genetic 'instruction'.

Previous studies with the European sea bass, a fish whose sex determination depends on a combination of genetic and environmental factors, had shown that starting with a normal sex ratio population -equal proportions of male and females, it was possible to obtain an all-male group just through an increase in water temperature during a critical period of early development.

The most intriguing observation was that effects of temperature were maximum at a moment when gonads were not differentiated nor had they even started to form. Why was this happening, what makes temperature override the genetic component and so early was, until now, a long-standing puzzle.

Now, a research lead by the Spanish National Research Council (CSIC) has found out the answer. The team, lead by Francesc Piferrer, a CSIC professor at the Institute of Marine Sciences, in Barcelona, describes the mechanism which is induced by increased temperatures and triggers aromatase gene silencing.

Aromatase is an enzyme that transforms androgens into estrogens, which are essential for the development of ovaries in all non-mammalian vertebrates. If there is no aromatase there are no estrogens, and without estrogens the development of ovaries is not possible. The research, that has been realized with the contribution of the Center for Genomic Regulation, in Barcelona, is being published this week in PLos Genetics.

Early effects

In the experiment, scientists exposed two groups of European seabass larvae at different temperatures, normal and high temperature, during their first weeks of life.

Results show that high temperature increases the DNA methylation of the gonadal aromatase promoter (cyp19a), which, in turn drives its silencing as its transcriptional activation is inhibited. In the group exposed to high temperature there were genetic females that were only partially affected and yet developed as females. However, there were other genetic females with the highest level of DNA methylation that therefore developed as males because aromatase was fully inhibited.

This is the first time that an epigenetic mechanism linking an environmental factor to a cellular mechanism related to the sexual determination has been described in any animal. Previously, only a similar mechanism had been described in some plants.

As researcher Francesc Piferrer points out, 'animals are affected very soon, before differences between females and males become visible in histological samples, which happens on the 150th day of life, and even before the gonads start to form, which happens on the 35th day of life'.

This work explains why a few degrees of temperature rise masculinize these animals, something relevant in a context of global change.

It also explains why many fishes raised on farms are males, since farmers raise larvae in warmer waters in order to accelerate their growth. Piferrer adds that 'sex determination by temperature is very common in reptiles. It will be interesting to see if a similar mechanism to the one described exists in this group of vertebrates'.

Sooners? coach to meet alma mater in Insight Bowl

TEMPE, Ariz. ? As Oklahoma?s defensive captain and one of the most eloquent players on either side of the ball, Travis Lewis had become a go-to guy for reporters, someone who could provide a non-slanted assessment of the team.

So when the senior linebacker zipped up over the final six weeks of the season, it was a pretty good indication of just how disappointing the year had gone for the Sooners.

?Everybody knew the expectations going into this season ? the fans did, we did, the coaches did,? Lewis said after breaking his silence on Wednesday. ?The most disappointing thing is we felt like we had that team. We felt like we had all the pieces in place this year. And we didn?t meet expectations.?

When Oklahoma (9-3) faces Iowa in today?s Insig3ht Bowl at Sun Devil Stadium, it will be the Sooners? 13th straight bowl ? every year since coach Bob Stoops took over the program ? and give them a chance at a nation-leading 33rd season with at least 10 wins.

Nice accomplishments, just not what was expected coming out of Norman.

Armed with one of the nation?s best quarterbacks Landry Jones and receivers in Ryan Broyles, with talented players at pretty much every position and a No. 1 ranking, the Sooners had aspirations of earning their second national title under Stoops and eighth overall.

They got off to a solid start, bumping off Florida State and Texas while winning their first six games. A 41-38 home loss to Texas Tech on Oct. 22 hurt, but, if the rest of the season unfolded just right, Oklahoma could still be right in the thick of the national-championship chase.

Following a resounding win over No. 8 Kansas State the next week, the Sooners? season started to unravel.

Broyles, an All-American and the NCAA?s all-time leader in receptions, tore a knee ligament against Texas A&M the following week. Oklahoma won that game, but followed with a loss to Baylor and ended the regular season two weeks later with a deflating 44-10 rout to Bedlam rival Oklahoma State.

A year after rolling over Connecticut in the Fiesta Bowl, the Sooners are back in the desert trying to put a strong finish on what?s been a frustrating season.

?Every year you are not going to be in the national championship game, but you still have to try and win each and every game you play,? Stoops said. ?That?s what we are trying to do.?

Iowa (7-5) doesn?t figure to be a walkover for the Sooners.

The Hawkeyes barely won half their games, but played a brutal schedule that included seven ranked teams. Iowa also has a bit of confidence in bowls, having won a school-record three straight, including 27-24 over Missouri in last year?s Insight Bowl.

The Hawkeyes entered last year?s game as underdogs and had to switch gears when their top running back was suspended. They enter this year?s game with almost identical circumstances: Oklahoma is favored by 14 and Iowa will be without running back Marcus Coker, who was suspended for violating the university?s student-athlete code of conduct.

?It is almost scary how similar the circumstances are,? Iowa coach Kirk Ferentz said.

The Insight Bowl will be the culmination of a long difficult year at Iowa.

During the offseason, the Hawkeyes had 13 players hospitalized for a muscle disorder called rhabdomyolysis that was caused by a team workout, leading to criticism of Ferentz and the program.

Iowa had some rough stretches during the regular season, losing two of its final three games, had defensive line coach Rick Kaczenski leave the program to pursue another coaching job and will be playing its final game with defensive coordinator Norm Parker, who?s retiring.

On top of that, they?ll try to replace Coker?s 1,384 yards and 15 touchdowns with a group of unproven running backs ? none of whom have more than 18 carries.

?We better be motivated and to have a chance in this game, we will have to play our absolute best in all three phases,? Ferentz said. ?We can?t open the door anywhere and expect to win.?

Especially with Oklahoma and Lewis looking to emphatically close the door on its season.

?I thought, maybe if I just quit the talking, my team would focus on playing and start winning ballgames,? Lewis said. ?I didn?t want to make excuses for our wins, for our losses. I wanted to just practice and play and let everything take care of itself.?

HBT: Ex-Red Sox reliever Okajima going to Yanks

Hideki Okajima spent nearly all of last season in the minors despite being paid $1.75 million by the Red Sox and now the veteran reliever will try to make it back to the majors with the Yankees.

David Waldstein of the New York Times reports that Okajima has agreed to a minor-league contract with the Yankees that includes an invitation to spring training.

At age 36 the odds are against Okajima reestablishing himself as a quality setup man, but he pitched very well at Triple-A with a 2.29 ERA and 48/9 K/BB ratio in 51 innings and if nothing else could be useful as a situational left-hander.

Okajima provided an excellent return on the Red Sox?s investment after signing out of Japan in 2006, throwing 246 innings with a 3.11 ERA while being paid around $8.5 million.

Asian stocks down on mixed US, Japan economic news

BANGKOK --?

World stocks markets fell Wednesday, with trading thinned by year-end holidays and mixed economic news out of the U.S. and Japan.

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

European stocks dropped in early trading. Britain's FTSE 100 fell 0.2 percent to 5,501.25. Germany's DAX was 0.9 percent lower at 5,839.98 and France's CAC-40 lost 0.4 percent to 3,092.01. Wall Street also appeared headed for a lower opening. Dow Jones industrial futures rose 0.2 percent to 12,199 while S&P 500 futures dipped 0.3 percent to 1,256.60.

Earlier in Asia, trading was subdued, as it typically is between the Christmas holiday and New Year's.

Japan's Nikkei 225 index fell 0.2 percent to close at 8,423.62. Hong Kong's Hang Seng Index fell 0.6 percent to 18,518.67, while South Korea's Kospi lost 0.9 percent to 1,825.12. Australia's S&P ASX 200 lost 1.3 percent to 4,088.80. Benchmarks in Singapore, Taiwan and Indonesia were also lower.

Japan's industrial output dropped a seasonally adjusted 2.6 percent last month - the first decline in two months. But the negative news was mitigated by expectations of rebounding manufacturing and production this month and next, which helped to mute stock market losses.

The Shanghai Composite Index reversed course after early losses, rising 0.2 percent to 2,170.01. But the smaller Shenzhen Composite Index sank 0.5 percent at 849.76.

Some investors were "dumping shares" because Beijing has failed to take steps they expected to stimulate slowing economic growth, said Peter Lai, investment manager for DBS Vickers in Hong Kong.

"Some investors believed there would be a reduction in interest rates or the bank reserve ratio. But this hasn't happened," Lai said.

Tokyo Electric Power plunged 11.8 percent, a day after Japanese Industry Minister Yukio Edano suggested that the embattled utility be put under temporary state control and warned the company against resorting to electricity bill hikes.

TEPCO operates the Fukushima Dai-ichi nuclear power plant, which was heavily damaged in the March earthquake and tsunami, and owes massive compensation payments to people and companies harmed by a nuclear disaster at the plant.

Hong Kong-listed property shares also slumped. China Overseas Land & Investment slid 3 percent. China Resources Land lost 2.7 percent.

China Mengniu Dairy, the country's biggest dairy company, plummeted 24 percent in Hong Kong after acknowledging that a cancer-causing toxin had been found in milk produced by the company. Mengniu apologized and said no tainted milk had made it to the market. The government blamed the problem on bad feed given to cows.

Retail shares also slid on growing anxiety over the global economy in 2012. Hong Kong-listed jewelry retailer Chow Sang Sang shed 4 percent. Australian department store chain David Jones fell 2.1 percent and Woolworth's lost 0.9 percent.

On Wall Street on Tuesday, the Dow Jones lost less than 0.1 percent to close at 12,291.35. The S&P 500 was up marginally to 1,265.43. The Nasdaq composite rose 0.3 percent to 2,625.20.

U.S. consumer confidence surged to an eight-month high, but home prices fell in 19 of the 20 cities tracked by the Standard & Poor's/Case-Shiller index. That report dampened investors' enthusiasm about a jump in consumer confidence to the highest level since April.

Benchmark crude oil rose 2 cents to $101.36 per barrel in electronic trading on the New York Mercantile Exchange. The contract rose $1.66 to finish at $101.34 per barrel on the Nymex on Tuesday.

In currency trading, the euro fell to $1.3075 from $1.3069 late Tuesday in New York. The euro has been weak because of worries about Europe's government debt crisis. It is still trading just above an 11-month low of $1.2943 reached on Dec. 14.

The dollar fell to 77.73 yen from 77.85 yen.

(AP) ? Four-star general-turned-CIA director David Petraeus was urged to resign as Afghanistan war commander over President Barack Obama's decision to quickly withdraw surge forces, according to a new insider's look at Petraeus' 37-year Army career.

Conservative writer Max Boot had urged he take that course of action, but Petraeus decided that resigning would be a "selfish, grandstanding move with huge political ramifications" and that now was "time to salute and carry on," according to a forthcoming biography.

"Director Petraeus has publicly stated that he never contemplated resignation," CIA spokeswoman Jennifer Youngblood said Thursday.

Author and Petraeus confidante Paula Broadwell had extensive access to the general in Afghanistan and Washington for "All In: The Education of General David Petraeus," due from Penguin Press in January. The Associated Press was given an advance copy.

The account traces Petraeus' career from military academy cadet to his command of two wars deemed unwinnable: Iraq and Afghanistan. Co-authored with The Washington Post's Vernon Loeb, the nearly 400-page biography is part history lesson through Petraeus' eyes, part hagiography and part defense of the counterinsurgency strategy he applied in both wars.

Critics of counterinsurgency argue the strategy has not yet proved a success, with violence spiking in Iraq after the departure of U.S. troops, and Afghan local forces deemed ill-prepared to take over by the 2014 deadline.

The book unapologetically casts Petraeus in the hero's role, as in this description of the Afghanistan campaign: "There was a new strategic force released on Kabul: Petraeus' will."

Broadwell does acknowledge that Petraeus rubs some people the wrong way.

"His critics fault him for ambition and self-promotion," she writes. But she adds that "his energy, optimism and will to win stand out more for me."

The book also is peppered with Petraeus quotes that sound like olive branches meant to soothe Obama aides who feared Petraeus would challenge their boss for the White House.

"Petraeus tried to make clear that he and Obama were in synch," Broadwell writes of Petraeus' Senate testimony on the Afghan war.

The book describes Petraeus' frustration at still being labeled an outsider from the Obama administration, even as he retired from the military at Obama's request before taking the job last summer as the CIA's 20th director.

The book depicts Petraeus' rise at an unrelenting, near-superhuman pace. He starts his career as a fiercely competitive cadet known as "Peaches," where he famously wooed the school superintendent's daughter, Holly Knowlton. He went on to command the 101st Airborne Division as part of the invasion of Iraq, then masterminded the rewrite of the Army and Marine Corps' counterinsurgency training manual before returning to command the surge in Baghdad. He was then appointed to head Central Command, overseeing the campaigns in Iraq and Afghanistan as well as military affairs across much of the Gulf and the Mideast.

He accepted a cut in authority and pay to lead the Afghanistan war campaign when Gen. Stanley McChrystal was forced to resign after a Rolling Stone magazine article that "scorched the general (McChrystal) and his aides, caricaturing them as testosterone-addled frat boys as they insulted Obama" and other officials, Broadwell writes.

She describes how Petraeus' first act was to lift McChrystal's restrictions on the use of force ? especially on airstrikes ? if civilians were nearby.

"There is no question about our commitment to reducing civilian loss of life," Petraeus told his staff. There was, however, "a clear moral imperative to make sure we are fully supporting our troops in combat."

Broadwell adds that the problem, according to Petraeus, was less McChrystal's order than how it was even more strictly re-interpreted by lower commanders.

In her account, Petraeus also faults McChrystal for overpromising and underdelivering in places like Taliban-riddled Marjah in the south, producing months of embarrassing headlines that hurt the war effort back in Washington.

But the book also includes Petraeus' own Rolling Stone-esque moment, when he was quoted badmouthing the White House in Bob Woodward's latest book, "Obama's Wars." A frustrated Petraeus is described as telling his inner circle, on a flight after a glass of wine, that "the administration was (expletive) with the wrong guy."

"Petraeus later expressed his displeasure to all of them for betraying his confidence," Broadwell wrote. "But he knew he was ultimately responsible for making the intemperate remark," a candid admission, through Broadwell, of his lapse in judgment.

He also concedes the Afghan war is not yet won.

"He had wanted to hand (Marine Corps Gen. John) Allen ... a war that had taken a decisive turn," Broadwell writes of what had been Petraeus' goal for his successor. "He knew that, despite the hard-fought progress, that wasn't yet the case."

Yet that admission also presents a get-out clause when combined with the book's account that he considered resigning over the rapid drawdown of troops, neatly removing Petraeus from responsibility if the war goes wrong.

And the account does nothing to puncture the mythology his troops built up around him, something an early mentor, retired Gen. Jack Galvin, told Petraeus to embrace.

"They want you to be bigger than you are, so they magnify you," Galvin said in an interview with Broadwell. "Live up to it all with the highest standards of integrity. You become part of a legend."

"All In" fits neatly into that.___
