(AP) ? The last U.S. soldiers rolled out of Iraq across the border into neighboring Kuwait at daybreak Sunday, whooping, fist bumping and hugging each other in a burst of joy and relief. Their convoy's exit marked the end of a bitterly divisive war that raged for nearly nine years and left Iraq shattered, with troubling questions lingering over whether the Arab nation will remain a steadfast U.S. ally.

The mission cost nearly 4,500 American and well more than 100,000 Iraqi lives and $800 billion from the U.S. Treasury. The question of whether it was worth it all is yet unanswered.

After a ceremony Thursday in Baghdad formally marking the end of the war, the timing and all other details of the departure of the last convoy were kept under tight secrecy out of security concerns for about 500 troops and more than 110 vehicles that were part of it. The low-key end to the war was just another reminder of how dangerous Iraq remains, even though violence is lower now than at any other time since the 2003 invasion.

The last convoy of MRAPs, heavily armored personnel carriers, made a largely uneventful journey out except for a few equipment malfunctions along the way. It was dark and little was visible through the MRAP windows as they cruised through the southern Iraqi desert. The 210-mile trip from a base in southern Iraq took about five hours.

When the convoy crossed the border into Kuwait around 7:45 a.m. local time, the atmosphere was subdued inside one of the vehicles, with no shouting or yelling. Along the road, a small group of Iraqi soldiers waved to the departing American troops.

"My heart goes out to the Iraqis," said Warrant Officer John Jewell, acknowledging the challenges ahead. "The innocent always pay the bill."

Soldiers standing just inside the crossing on the Kuwaiti side of the border waved and snapped photos as the final trucks rumbled over.

"I'm pretty excited," said Sgt. Ashley Vorhees. "I'm out of Iraq. It's all smooth sailing from here."

The war that began in a blaze of aerial bombardment meant to shock and awe the dictator Saddam Hussein and his loyalists ended quietly and with minimal fanfare.

President Barack Obama stopped short of calling the U.S. effort in Iraq a victory in an interview taped Thursday with ABC News' Barbara Walters.

"I would describe our troops as having succeeded in the mission of giving to the Iraqis their country in a way that gives them a chance for a successful future," Obama said.

In the final days, U.S. officials acknowledged the cost in blood and dollars was high, but tried to paint a picture of victory ? for both the troops and the Iraqi people now freed of a dictator and on a path to democracy. But gnawing questions remain: Will Iraqis be able to forge their new government amid the still stubborn sectarian clashes? And will Iraq be able to defend itself and remain independent in a region fraught with turmoil and still steeped in insurgent threats?

Many Iraqis, however, are nervous and uncertain about the future. Their relief at the end of Saddam, who was hanged on Dec. 30 2006, was tempered by a long and vicious war that was launched to find nonexistent weapons of mass destruction and nearly plunged the nation into full-scale sectarian civil war.

Some criticized the Americans for leaving behind a destroyed country with thousands of widows and orphans, a people deeply divided along sectarian lines and without rebuilding the devastated infrastructure.

"We are glad to see the last U.S. soldier leaving the country today. It is an important day in Iraq's history, but the most important thing now is the future of Iraq," said 25-year-old Said Hassan, the owner of money exchange shop in Baghdad. "The Americans have left behind them a country that is s falling apart and an Iraqi army and security forces that have a long way ahead to be able to defend the nation and the people."

Some Iraqis celebrated the exit of what they called American occupiers, neither invited nor welcome in a proud country.

Others said that while grateful for U.S. help ousting Saddam, the war went on too long. A majority of Americans would agree, according to opinion polls.

The quiet exit stood in sharp contrast to the high-octane start of the war, which began before dawn on March 20, 2003, with an airstrike in southern Baghdad where Saddam was believed to be hiding. U.S. and allied ground forces then stormed across the featureless Kuwaiti desert, accompanied by reporters, photographers and television crews embedded with the troops.

The last few thousand U.S. troops left in orderly caravans and tightly scheduled flights. They pulled out at night in hopes it would be more secure and left in time for at least some of the troops to join families at home for the Christmas holidays.

The final convoys began to leave on Saturday evening from Camp Adder base near Nasiriyah, about 200 miles (320 kilometers) southeast of Baghdad. The vehicles lined up in an open field to prepare and soldiers went through last-minute equipment checks to make sure radios, weapons and other gear were working.

Gen. Lloyd Austin, the commanding general for Iraq, walked through the rows of vehicles, talking to soldiers over the low hum of the engines. He thanked them for their service and reminded them to stay vigilant on their final mission.

"I wanted to remind them that we have an important mission left in the country of Iraq. We want to stay focused and we want to make sure that we're doing the right things to protect ourselves," Austin said.

Austin also presided over the last casing ceremony in Iraq for the battalion that made up the bulk of the people leaving on the last convoys. In the ceremony, the unit puts away their flags or "cases" them in preparation for departure.

After the ceremony on Saturday evening, the commander of the Special Troops Battalion, Lt. Col. Jack Vantress told his soldiers:

"We are closing the book on an operation that has brought freedom to a country that was repressed. When the sun comes up, we'll be across the berm. Laser focus. Laser focus. You've got time, hours of road to go. There are people out there who still want to hurt you."

The final troops completed the massive logistical challenge of shuttering hundreds of bases and combat outposts, and methodically moving more than 50,000 U.S. troops and their equipment out of Iraq over the last year ? while still conducting training, security assistance and counterterrorism battles.

As of Thursday, there were two U.S. bases and less than 4,000 U.S. troops in Iraq ? a dramatic drop from the roughly 500 military installations and as many as 170,000 troops during the surge ordered by President George W. Bush in 2007, when violence and raging sectarianism gripped the country. All U.S. troops were slated to be out of Iraq by the end of the year, but officials are likely to meet that goal a bit before then.

"The biggest thing about going home is just that it's home," Staff Sgt. Daniel Gaumer, 37, from Ft. Hood, Texas said before the convoy left Camp Adder. "It's civilization as I know it, the Western world, not sand and dust and the occasional rain here and there. It's home."

Spc. Jesse Jones, a 23-year-old who volunteered to be on the last convoy, said: "It's just an honor to be able to serve your country and say that you helped close out the war in Iraq. ... Not a lot of people can say that they did huge things like that that will probably be in the history books."

The total U.S. departure is a bit earlier than initially planned, and military leaders worry that it is premature for the still maturing Iraqi security forces, who face continuing struggles to develop the logistics, air operations, surveillance and intelligence-sharing capabilities they will need in what has long been a difficult region.

Obama's earlier contention that all American troops would be home for Christmas, at least 4,000 forces will remain in Kuwait for some months. The troops will be able to help finalize the move out of Iraq, but could also be used as a quick reaction force if needed.

The U.S. plans to keep a robust diplomatic presence in Iraq, foster a deep and lasting relationship with the nation and maintain a strong military force in the region.

U.S. officials were unable to reach an agreement with the Iraqis on legal issues and troop immunity that would have allowed a small training and counterterrorism force to remain. U.S. defense officials said they expect there will be no movement on that issue until sometime next year.

Obama met in Washington with Iraqi Prime Minister Nouri al-Maliki last week, vowing to remain committed to Iraq as the two countries struggle to define their new relationship.

Ending the war was an early goal of the Obama administration and will allow the president to fulfill a crucial campaign promise during a politically opportune time. The 2012 presidential race is roiling and Republicans are in a ferocious battle to determine who will face off against Obama in the election.

Capt. Mark Askew, a 28-year-old from Tampa, Florida who was among the last soldiers to leave, said the answer to the question of whether the Iraq war was worth the cost will depend on what type of country and government Iraq ends up with years from now, whether they are democratic, respect human rights and are considered an American ally.

"It depends on what Iraq does after we leave," he said, speaking before the final convoy departed. "I don't expect them to turn into South Korea or Japan overnight."

Russia sells new batch of fighter jets to India (AP)

MOSCOW ? Russia signed a deal Friday to provide India with 42 fighter jets, but the two nations have failed to strike a deal on a controversial nuclear power plant.

Indian Prime Minister Manmohan Singh said that New Delhi will fit the Sukhoi Su-30MKI fighter jets with additional locally produced electronics. The jets will be assembled in India.

India had earlier signed several contracts for the delivery of 230 Su-30MKIs, most of which are being assembled locally. The long-range jets are custom-designed for the Indian Air Force.

India has been a leading customer for Russian weapons since the Soviet times, buying combat jets, missiles, navy ships and other weapons worth billions of dollars. Russian weapons still acount for the bulk of the Indian military arsenals.

Indian and Russian officials, however, failed to sign a deal to complete the Koodankulam nuclear plant in the southern Indian state of Tamil Nadu.

Russia had pledged to build two of the four reactors at the $3 billion plant, but the construction has been delayed due to protests by local residents concerned about the plant's safety.

As part of his two-day visit to Russia, Singh met with Russian President Dmitry Medvedev. Both leaders pledged to strengthen the decades-old bilateral ties.

Syrians protest against Assad after Russia UN move (Reuters)

BEIRUT (Reuters) ? Syrian forces killed 13 people on Friday during widespread protests against President Bashar al-Assad, activists said, a day after Syria's big power ally Russia sharpened its criticism of Damascus in a draft United Nations resolution.

Most of the deaths were in the city of Homs, they said, a hotbed of resistance to a crackdown on nine months of protests which has killed 5,000 people according to the United Nations and provoked Western and Arab League sanctions on Damascus.

State media said there were no deaths or injuries on Friday, despite what they said were attacks by "armed terrorist groups" on security forces. Syria has barred most independent media, making it hard to verify accounts by activists and authorities.

About 200,000 people marched in separate districts of Homs, the British-based Syrian Observatory for Human Rights said, and footage broadcast by Al Jazeera television showed mock gallows where effigies were hanged, including two of Assad and his father, who seized power in Syria four decades ago.

If confirmed, it would be one the biggest turnouts by demonstrators for several weeks.

Russia presented a new, beefed-up draft resolution on the violence to the U.N. Security Council on Thursday, offering a chance for the 15-nation panel to overcome deadlock and deliver its first statement of purpose on Assad's crackdown.

The council has been split, with Western countries harshly critical of Syria pitted against Russia, China and non-aligned countries that have avoided blaming Assad for the violence.

France, which has led Western rebukes of Assad, welcomed what it said was Moscow's recognition of the deteriorating situation in Syria, but said Russia was wrong to equate Assad's crackdown with violence perpetrated by his opponents.

Assad has denied that Syrian forces have been ordered to kill demonstrators, blaming armed groups for the bloodshed. He said 1,100 soldiers and police have been killed since the uprising erupted in March, inspired by other unrest in the Arab world that has toppled three autocratic leaders this year.

An armed insurgency has begun to eclipse civilian protests, raising fears Syria could descend into civil war. On Thursday army deserters killed 27 soldiers and security personnel in the southern province of Deraa, an activist group said.

State news agency SANA reported that security forces defused several explosives in Damascus and Hama provinces on Friday.

It is the most serious challenge to the 11-year rule of Assad, 46, whose family is from the minority Alawite sect and has ruled majority Sunni Muslim Syria since 1970.

The United States and European Union have imposed sanctions and called on Assad to step down. Neighboring Turkey has taken similar steps and even the Arab League has declared sanctions against Syria, although it has several times extended a deadline for Syria to approve a formula for ending the crisis.

In the latest sign of the heavy economic price Syria is paying for its repression of dissent, Turkey said on Friday that Damascus would lose more than $100 million a year in transport revenue as Ankara bypasses the turbulent country by opening alternative export routes to the Middle East and Gulf.

"ARAB LEAGUE IS KILLING US"

Arab governments called off a foreign ministers' meeting due to discuss a response on Saturday to Assad's iron fist policy towards unrest, Egypt's state news agency MENA reported.

A source at Arab League headquarters in Cairo gave no reason for the cancellation. A lower-level meeting of its ministerial committee on Syria will go ahead in Qatar on Saturday, the source said. The committee includes the foreign ministers of Egypt, Sudan, Oman, Qatar and Algeria.

Friday's protests were held under the slogan of "The Arab League is Killing us," reflecting demonstrators' frustration at what they see as the organization's ineffective response.

At the U.N. Security Council in October, Russia and China vetoed a European draft resolution that threatened sanctions. Russia has circulated its own draft twice but it was criticized by Western nations for blaming the violence equally on the government and opposition.

The draft floated unexpectedly by Russia on Thursday expands and toughens Moscow's previous text, adding a new reference to "disproportionate use of force by Syrian authorities.

Obtained by Reuters, the draft also "urges the Syrian government to put an end to suppression of those exercising their rights to freedom of expression, peaceful assembly and association."

Reports by Human Rights Watch and a U.N.-backed independent investigation have concluded that Syrian government forces were given "shoot to kill" orders when confronting demonstrators.

STRONGER TEXT

Russia's U.N. Ambassador, Vitaly Churkin, told reporters that the latest draft resolution "considerably strengthens all aspects of the previous text" and that "clearly the Syrian authorities are singled out in a number of instances."

He said Russia did not believe both sides in Syria were equally responsible for violence, but acknowledged the text called on all parties to halt violence and contained no threat of sanctions, which he said Moscow continued to oppose.

Western officials welcomed the move but Paris said the draft "has elements that are not acceptable in their current form."

"For France, it is a positive development that Russia has decided to recognize that the serious deterioration of the situation in Syria merits a Security Council resolution," Foreign Ministry spokesman Bernard Valero told a news briefing.

Calling the council's inaction scandalous, Valero said a resolution should be swiftly adopted to condemn crimes against humanity in Syria and back a credible political solution.

U.S. Defence Secretary Leon Panetta told reporters in Ankara that the Russian draft showed the international community was increasingly coming together to "say to Syria and to the Assad regime that we can no longer tolerate the kind of killings that have gone on...(and) that Assad needs to step down."

Square Enix servers hacked, 1.8 million users affected (Digital Trends)

final fantasy 7This is shaping up to the year of high-profile hacker attacks in the gaming world, as game developer Square Enix announced this week that 1.8 million user accounts were compromised as a result of a recent online security breach.

The developers responsible for the Final Fantasy and Dragon Quest game franchises reported yesterday that a hacker ?may have gained unauthorized access to a particular Square Enix server? and took its websites in Japan and the U.S. offline in order to assess the extent of the attack. Subsequent reports indicate that one million Japanese users? accounts were affected, as well as those of 800,000 users in the U.S.

Fortunately, the accounts affected by the hack contained no credit card information, but they did contain customers? names, email addresses, postal addresses, and phone numbers.

?There is no possibility of any credit card information leak,? stated Square Enix in its official statement regarding the security breach. ?We have asked our customers to be aware of the incident in case they receive suspicious messages using our name.?

This is the second attack on Square Enix servers this year. Back in May, a hacker breached security on the developer?s European servers and leaked the email addresses of 25,000 customers and the resumes of 250 job applicants.

Shape, fit of reproductive organs evolve quickly and in concert, leaving size behind

BLOOMINGTON, Ind. -- Believed critical for determining which individuals can -- or cannot -- successfully reproduce with each other, genitalia not only figure prominently in the origin of new species, but are also typically the first type of trait to change as new species form.

Today, new international research led by Indiana University shows that as populations and species diversify, the exact shape and fit of genitalia steals the show over size.

In data gathered from populations isolated for less than 50 years, to species separated for millions of years, researchers studying scarab beetles have shown that both male and female genitalia have evolved extremely rapidly and have done so along parallel timetables. But most surprisingly, this codivergence occurred much faster in, or was even restricted to, genital shape rather than size.

"Parallel evolutionary divergence in male and female genitalia was something scientists long suspected or assumed, but we've had little or no data to support this assumption," said lead author Armin Moczek, an associate professor in the IU Bloomington College of Arts and Sciences' Department of Biology. "But to see that this parallel divergence is so much faster for genital shape than size is a big surprise."

Too much focus in past research on sizes, rather than shapes of genitalia -- which is much harder to measure in arthropods -- may have misled past research in judging how genitalic evolution may enable diverging populations to evolve into separate species unable to hybridize.

Just as interesting is the remarkably short time frame -- as short as populations being separated by 50 years -- that would support the notion that it may be surprisingly easy for the genitalia of males and females to evolve concomitantly, and for males and females of different populations to diverge from each other to a degree approximating what is normally seen only between species separated for more than 10,000 years.

"If it is correct that such divergences aid in establishing reproductive isolation -- something we did not test, but which is widely assumed -- then by extension this finding suggests that evolving new species, or at least getting populations started in the process, may be much easier and faster than we generally assume," Moczek said.

In this research, the team examined the female genital tract and the male copulatory organs of eight populations of five different species of Onthophagus beetles, including three populations in the Eastern U.S., Western Australia and Eastern Australia which were established from an ancestral Mediterranean population in the 1970s as part of a biocontrol program.

The researchers focused on male and female genitalic parts that interact physically during copulation -- the female pygidium, a moveable plate that provides grooves and pits that serve as anchor points for the correct positioning of male genitalia, and the male parameres, part of the male copulatory organ, which includes projections that fit into said grooves and pits of the female pygidium.

The research team then examined how shapes and sizes of these interacting female and male copulatory structures had diverged across populations and species using landmark-based geometric morphometric tools, a key methodology that enabled the team to examine differences in shape irrespective of differences in size.

"Once we compared the patterns of divergence across sexes we found that the relative sizes of male and female copulatory organs do evolve, but do so independent of each other. But for genital shape, we found a striking signature of parallel divergence, suggesting that male and female copulatory structures that are linked mechanically during copulation may diverge in concert with respect to their shapes," Moczek said. "Our results also suggest that genital divergence in general, and co-divergence of male and female genital shape in particular, can evolve over an extraordinarily short time frame."

###

The National Science Foundation's support of Moczek's research in the evolutionary developmental biology of horned beetles has provided much of the infrastructure that enabled this study.

Co-authors with Moczek on the research article "Shape -- but Not Size -- Codivergence Between Male and Female Copulatory Structures in Onthophagus Beetles," first available online here Dec. 14, in PLoS ONE, were Anna L. M. Macagno, Astrid Pizzo, Claudia Palestrini and Antonio Rolando of Universit degli Studi di Torino; and Harald F. Parzer, also of IU's Department of Biology.

With the Black Eyed Peas recently announcing their hiatus after a star-studded sendoff show in Miami, the band's members are not wasting time getting busy.

Leader will.i.am. has already dropped the eye-popping video for "T.H.E. (The Hardest Ever)," the electro-fueled first single from his new solo album, while member apl.de.ap is focusing on non-musical ventures.

Apl announced the launch of this week of the "Charity Dreams" auction benefiting education in his native Philippines. The rapper, who is an educational ambassador for the island nation, is upping the ante on celebrity auctions in a major way with the "We Can Be Anything" event.

The auction — which begins pre-registration this week at CharityDreams.com and lasts through 9 p.m. ET Wednesday — allows fans to start the bidding at just 99 cents for a huge prize package that may end up being the most affordable donation on the planet.

Not only will the winner get a private-jet flight out to Los Angeles to spend time in the studio to watch as Apl creates a custom track in their honor, but the BEP rapper will also cut a custom disc of the session and serve as the DJ at the winner's birthday party, where he will spin the song for the top prize-getter and 50 of his or her friends. The winning bidder will also get a 2012 collector's edition Ferrari, $250,000 in cash and a trip to Las Vegas with 10 friends to spend New Year's Eve with Fergie while staying in the "Real World" penthouse suite.

Once 1 million people pre-register and the bidding begins, all the money donated in bids will go toward building 10,000 classrooms in the Philippines and improving education in the nation. And even before the first brick is laid, bidders will be able to join together to help build "virtual classrooms."

According to a release announcing the effort, every bid will allow users to buy virtual books, pencils, chairs, desks, etc., and help build virtual classrooms in an effort to combine gaming, social networking and philanthropy. Each time a bidder finishes a virtual classroom, an actual classroom will be named for that bidder once construction is completed on the new schools.

In a unique twist, the initial fee to place a charity bid is 99 cents, with the bidding price beginning at $0. Organizers expect the final package to go for no more than a few hundred dollars thanks to a system in which each bid increases the top price by just a fraction of a penny.

Each bid will also entitle users to an app, music download or play list curated by Apl and featuring an exclusive song or the chance to have Apl follow you on Twitter.
