Iraq's Christians face hardship, but peaceful Easter also highlights promise

War and persecution by newly empowered Islamist forces drove Iraq's Christians away, halving the population of the once-thriving community. But a new Christian leader vows to rebuild.

Iraqi Christians celebrated a largely peaceful Easter under heavy security as a newly-elected Catholic leader pledged to try to stop an exodus from the Middle East and rebuild the battered church community.

Soldiers and federal policemen in armored vehicles were posted outside churches and security patrols were increased in Christian areas. Because of Baghdad?s fragile security, at many churches the main Easter service traditionally ending at dawn Sunday morning was held Saturday night.

Iraq?s Christian population, which was believed to top 1 million before the war, dropped to half that as Christians fled attacks on their neighborhoods and churches. Many of them have resettled in the west. Tens of thousands of Christians who went to neighboring Syria for safety or to apply for refugee status are just now beginning to return as fighting rages in that country.

On Sunday morning in Baghdad, church bells rang out as families with children dressed in new Easter clothing greeted each other on the steps in the spring sunshine. The?post-Saddam?Iraqi government has continued a decades-long tradition of granting Christian government workers a two-day holiday for Easter.

At the main Chaldean Catholic mass late last night, the new Chaldean patriarch, dressed in a red cape and gold-embroidered, stone-encrusted headdress celebrated Easter with a few hundred parishioners in a mass carried live on state television.?

Louis Raphael Sako was elected last month by a conference of bishops in Rome to head the Chaldean Catholic church, the largest of the Christian denominations in Iraq and Syria. The patriarch, whose official title is Patriarch of Babylon, is the most senior religious official of the church. It traces its roots back to Jesus's apostle St. Thomas,? who preached the gospel as he traveled through Iraq and Syria on his way to India.

Mr. Sako, who met Iraqi Prime Minister Nouri al-Maliki last week to urge him to meet with political opponents, called in his sermon yesterday for Iraqis to unite to help build prosperity and stability.

In an interview this week, Sako made clear that, after what he described as several years of stagnation, the church would focus on making it safe enough for Christians to remain in Iraq and on strengthening ties with the Muslim community.

?We must stay. This is our history. This is our patrimony. When we leave everything will leave with us,? says Sako. ?Other Iraqis are also persecuted, not only Christians, so there is a solidarity among us? They have to stay to struggle with the others.?

Christian exodus

More than 1,000 Christians have been killed in the past 10 years and 60 churches have been attacked since Saddam Hussein was toppled, according to Sako. Although that is only a fraction of the number of Muslim victims, it is a much larger percentage of the overall community.

In the worst of the attacks, gunmen and suicide bombers stormed Our Lady of Salvation Syriac Catholic church during mass in 2010, killing 58 people, including priests. A group affiliated with Al Qaeda in Iraq claimed responsibility for the attack.? The church has re-opened but is now hidden behind high concrete walls, guarded by soldiers, and closed to all but regular parishioners.

That attack and fragile security in Baghdad, Mosul, and other centers with large Christian communities, sparked a new exodus.?

A lack of priests has left only 18 Chaldean parishes, down from 30. In some areas where large numbers of Christians have been displaced and there are no priests, mass is held only once a month instead of daily or weekly.

The Chaldean population in Syria doubled to about 30,000?as Iraqi Christians fled there when it was safer. Some are now beginning to come back?as their country of refuge falls apart.

?Sako says emigration from Iraq mirrors the movement of?Christians from other countries, where the Arab Spring has toppled dictators, but?also removed much of the protection for Middle East Christians.?

?They are scared ? all Christians, not only Chaldeans,? says Sako. ?The Arab spring is not a spring. It has changed even in Egypt, in Tunisia, in Algeria, in Libya. Now the Islamists have the power ? the authority.?

?People are afraid of a kind of Islamic state as it was in the Seventh century where Christians would be considered a second class citizen...We want to keep?[Iraq's Christians]?? to convince them that they can stay here and to live a good life,? he says.?

Still 'more freedom' here

While some are still trying to leave Iraq, many of those who stayed form a tight-knit community,?remembering the diverse, more tolerant country that existed before the war and determined not to leave it.

?I will never leave Iraq. We have more freedom here than any other country in the region,? says a retired academic attending mass at St. Joseph?s last night. However, the woman said she did not want her name used because she lives in Mosul, the site of many of the attacks on priests and parishioners. Her sister and brother-in-law were wounded in the attack at Our Lady of Salvation and are still undergoing medical treatment in France.

At the Easter ceremony at St. Joseph?s, a female parishioner delivered the reading from the gospel while altar girls joined boys in the procession. Young women in tight jeans with long, flowing hair stood next to older women in black with lace scarves on their heads. ?

Sako ? who has studied Islam and speaks French, English, Italian, and German in addition to Arabic and the Aramaic spoken by most Chaldeans ? was known for building strong ties with Muslim religious and political officials when he was archbishop of Kirkuk before being elected patriarch.?

Kirkuk, in the middle of Iraq?s northern oil fields, is?disputed territory,?claimed by the central government, as well as Kurds and Turkmen.

He says Christians have been swept into the wider struggle for power in Iraq, which includes sectarian violence as well as conflict between the Kurdish and central governments.

?Shiites, Sunnis, Christians are also a victim of this conflict ? we don?t understand why they are attacking Christians because we don?t have any political ambition,? he says. ?We don?t want to set up a Christian regime in Iraq but there is a struggle between Shiite and Sunni ? and between the Kurds. The future is not known.??

Allergy season off to a bad start - HealthyLife

The sneezing, the itching, the watery eyes?oh my! Experts say the 2013 allergy season could start sooner and last longer in many parts of the country.

Dr. Kris Saririan of Certified Allergy & Asthma Consultants in Albany says a relatively mild winter, combined with a warm, wet spring, could create the perfect storm for those who suffer from seasonal allergies.

?We recommend that people get diagnosed and treated early to prevent the onset of symptoms. It is much more difficult to control the symptoms once the allergic reaction has begun,? said Dr. Saririan.

Symptoms of seasonal allergies include:

  • Runny nose & watery eyes
  • Sneezing & coughing
  • Itchy eyes, nose and throat

Dr. Saririan says it?s important for people to educate themselves about the symptoms associated with seasonal allergies. ?Unlike the common cold, which typically last 7-10 days, seasonal allergies can last several months.?

He also offered the below Healthy Tips for season allergy sufferers:

  • Get diagnosed
  • Begin treatment BEFORE allergy season begins
  • Stay indoors, shut windows, use air conditioning (when possible)
  • Avoid going outside on windy, dry days
  • Bathe at night to prevent bringing pollen into bed

Pregnant Man: Judge Refuses To Grant Thomas Beatie's Divorce

PHOENIX -- An Arizona judge on Friday refused to grant a divorce for a transgender Arizona man who gave birth to three children after beginning to change his sex from female.

Maricopa County Family Court Judge Douglas Gerlach ruled that Arizona's ban on same-sex marriages prevents Thomas Beatie's nine-year union from being recognized as valid.

Thomas Beatie was born a woman and underwent a double-mastectomy but retained female reproductive organs and gave birth to three children.

Gerlach said he had no jurisdiction to approve a divorce because there's insufficient evidence that Beatie was a man when he married Nancy Beatie in Hawaii.

Beatie is eager to end his marriage, but the couple's divorce plans stalled last summer when Gerlach said he was unable to find legal authority defining a man as someone who can give birth.

"The decision here is not based on the conclusion that this case involves a same-sex marriage merely because one of the parties is a transsexual male, but instead, the decision is compelled by the fact that the parties failed to prove that (Thomas Beatie) was a transsexual male when they were issued their marriage license," he wrote in Friday's ruling.

Gerlach's ruling also said it didn't address whether Arizona law allows a person who was born female to marry another female after undergoing a sex change operation.

The National Center for Lesbian Rights, which isn't involved in the Beatie divorce case, has said courts have declared marriages involving a transgender person invalid in a handful of cases across the country, but that those cases had different factual and legal issues than those in the Beatie case.

Thomas Beatie, known as "The Pregnant Man," was born Tracy Lehuanani Lagondino in Oahu, Hawaii. He began testosterone treatments in 1997 and underwent double mastectomy and chest reconstruction surgery in 2002. He changed his Hawaii driver's license to say he was a man and had a Hawaiian court approve his name change to Thomas.

Gerlach's ruling noted that Thomas Beatie halted the testosterone treatments and that he didn't provide documentation for any additional non-surgical efforts.

Thomas Beatie married his partner Nancy in early 2003 in Honolulu and became pregnant because Nancy was unable to have children. Thomas Beatie conceived with donated sperm and gave birth to children who are now 4, 3 and 2 years old. The couple eventually moved to Arizona.

Beatie has garnered a range of media attention, making the rounds on talk shows such as Larry King and Oprah Winfrey and winning a spot on Barbara Walters' list of "10 Most Fascinating People" in 2008, alongside President Barack Obama, conservative commentator Rush Limbaugh and swimmer Michael Phelps. He also published a book, "Labor Of Love: The Story of One Man's Extraordinary Pregnancy," the cover displaying an image of a shirtless Thomas sporting facial hair and holding a hand over his bare pregnant belly.

(AP) ? U.S. special operations forces handed over their base in a strategic region of eastern Afghanistan to local Afghan commandos on Saturday, a senior U.S. commander said. The withdrawal from Nirkh district meets a demand by Afghan President Hamid Karzai that U.S. forces leave the area after allegations that the Americans' Afghan counterparts committed human rights abuses there.

"We're coming out of Nirkh," said Maj. Gen. Tony Thomas, the top U.S. special operations commander in Afghanistan, in an interview with The Associated Press.

Attaullah Khogyani, spokesman for the governor of Wardak province outside Kabul in which Nirkh is located, confirmed that U.S. special operations forces withdrew and were replaced by a joint Afghan security forces team.

The transfer of authority ends a controversial chapter in which Karzai accused U.S. troops and an interpreter working with them of torture, kidnapping and summary execution of militant suspects in Nirkh ? charges U.S. officials including top commander in Afghanistan Gen. Joseph Dunford firmly denied.

The incident shows the larger struggle of Karzai's government to assert its authority over security matters, even as its green security forces try to assume control of much of the country from coalition forces on a rushed timeline, ahead of the scheduled withdrawal of most of coalition forces by December 2014.

Karzai had originally demanded the U.S. special operations forces pull out from the entire province, a gateway and staging area for Taliban and other militants for attacks on the capital Kabul. But he scaled down his demands to just the single district after negotiations with Dunford and other U.S. officials.

"President Karzai was specific, it's only for Nirkh, that was a provocative point," Thomas said. "American special operations forces are integral in the defense of Wardak from now until the foreseeable future."

U.S. commandos will also continue to visit the Afghan team in Nirkh.

"We're going to support them from a distance," Thomas said. "The reality is there was such a groundswell of support (from locals) in Wardak after the initial allegations that we're keeping several teams down there to work with the Afghan security forces for the future, with an idea that we'll transition over time."

The Americans are paired with and live alongside locally recruited and trained teams known as Afghan local police. Thomas said most of the local police will be paired with Afghan security forces by the end of the summer, with the Americans making occasional visits as they will do in Nirkh, to assess whether they need logistic or other support.

One Wardak government official expressed relief that the agreement crafted with Karzai did not mean the complete pullout of U.S. forces from the province, saying that local officials were worried their new forces would not yet be able to keep hardcore insurgents out of the area.

The official spoke on condition of anonymity because his comments run counter to public statements made by Karzai, that the Afghan security forces are ready for complete independence in Wardak.

UPS pays $40M to end online pharmacies probe

SAN FRANCISCO (AP) ? Shipping company UPS has agreed to pay $40 million to end a federal criminal probe connected to its work for online pharmacies.

The U.S. Department of Justice announced Friday that the Atlanta-based company would also "take steps" to block illicit online drug dealers from using their delivery service.

The DOJ says the fine amount is the money UPS collected from suspect online pharmacies.

UPS won't be charged with any crimes. Its biggest rival, FedEx Corp., has also been a target of the federal investigation.

The investigation of the two companies stems from a global campaign to shutter illicit online pharmacies launched in 2005. Since then, dozens of arrests have been made and thousands of websites closed worldwide as investigators continue to broaden the probe beyond the operators.

When cash is no longer legal tender

Workers at the Bureau of Engraving and Printing surrounded by piles of money (Discovery)Have you ever wondered what happens to all of the damaged dollar bills floating around the economy? How long does paper money actually last before it disintegrates into torn shreds or a pulpy mass that is indistinguishable from regular old paper? And at what point is paper money just too damaged to be used as legal tender?

On March 30 9 p.m. ET/PT, the Discovery Channel will give viewers an inside look at ?The Secret Life of Money,? which seeks to answer these questions along with offering many other insights into the world of money, including the history of how gold became a standard form of currency around the world.

David Kestenbaum and Jacob Goldstein from NPR?s "Planet Money" contributed to the special and chatted with Yahoo News about some of the stranger things they?ve learned about cash.

?To me, what?s most interesting is that there is a bigger idea at work here: Money is this thing that we take for granted,? Goldstein said. ?When you stop and think about money, it gets really weird, really fast.?

For example, if your money is damaged, you can legally exchange it with the Bureau of Engraving and Printing. But only to a point. The bureau says it receives upwards of 300 envelopes per day, containing ?torn, blackened, blood-soaked, shrunken or otherwise maimed money.? However, so long as 51 percent of that blood-soaked bill remains intact, you can get a freshly issued replacement bill.

?It?s not paper the way we normally think of paper. It?s 75 percent cotton and 25 percent linen. It?s like a T-shirt,? Kestenbaum says, explaining why money is actually more physically durable than some might think.

Still, that hasn?t stopped thousands of people each year from testing its limits in strange ways.

For example, one Florida man attempted to dry his money after it became wet by putting it in the microwave. But instead of returning to its crisp, clean form, the money was crisped and burst into flames.

These sort of incidents resulted in the bureau exchanging $28 million worth of paper money in 2011 alone.

Of course, Goldstein and Kestenbaum note that similar incidents are on the decline as money moves toward becoming a predominantly electronic transaction between buyer and seller.

?There is no truck full of dollar bills going from my employer?s bank to my bank,? Goldstein says, noting that the very basic idea of money is really more about trust than physical value. ?The U.S. dollar is already basically an electronic currency.?

And with the advent of independent currency providers such as Bitcoin, some people are trying to establish that trust without relying on a government.

Still, Kestenbaum says that for all its shortcomings, paper money is likely to stay with us for years to come. ?I am more bearish on the future of physical money,? he said. ?At some point, we won?t be using cash at all. Not in the next year, but in 50 years? Probably.?

Ironically, one of the reasons Goldstein and Kestenbaum say the U.S. dollar has a future in its physical form is its popularity outside of America. They note that there are currently more $100 bills outside the U.S. than within the borders of the country that printed them.

If you add up all of the cash, "there?s a lot missing because of how much is used overseas,? Kestenbaum said.

Smoking immediately upon waking may increase risk of lung and oral cancer

The sooner a person smokes a cigarette upon waking in the morning, the more likely he or she is to acquire lung or oral cancer, according to Penn State researchers.

"We found that smokers who consume cigarettes immediately after waking have higher levels of NNAL -- a metabolite of the tobacco-specific carcinogen NNK -- in their blood than smokers who refrain from smoking a half hour or more after waking, regardless of how many cigarettes they smoke per day," said Steven Branstetter, assistant professor of biobehavioral health.

According to Branstetter, other research has shown that NNK (4-(methylnitrosamino)-1-[3-pyridyl]-1-butanone) induces lung tumors in several rodent species. Levels of NNAL (4-(methylnitrosamnino)-1-(3-pyridyl)-1-butanol) in the blood can therefore predict lung cancer risk in rodents as well as in humans. In addition, NNAL levels are stable in smokers over time, and a single measurement can accurately reflect an individual's exposure.

Branstetter and his colleague Joshua Muscat, professor of public health sciences, examined data on 1,945 smoking adult participants from the National Health and Nutrition Examination Survey who had provided urine samples for analysis of NNAL. These participants also had provided information about their smoking behavior, including how soon they typically smoked after waking.

The researchers found that around 32 percent of the participants they examined smoked their first cigarette of the day within 5 minutes of waking; 31 percent smoked within 6 to 30 minutes of waking; 18 percent smoked within 31 to 60 minutes of waking; and 19 percent smoked more than one hour after waking. In addition, the researchers found that the NNAL level in the participants' blood was correlated with the participants' age, the age they started smoking, their gender and whether or not another smoker lived in their home, among other factors.

The team published its results in the March 29 issue of the journal Cancer, Epidemiology, Biomarkers and Prevention.

"Most importantly, we found that NNAL level was highest among people who smoked the soonest upon waking, regardless of the frequency of smoking and other factors that predict NNAL concentrations," Branstetter said. "We believe these people who smoke sooner after waking inhale more deeply and more thoroughly, which could explain the higher levels of NNAL in their blood, as well as their higher risk of developing oral or lung cancer. As a result, time to first cigarette might be an important factor in the identification of high-risk smokers and in the development of interventions targeted toward early-morning smokers."

The researchers found that around 32 percent of the participants they examined smoked their first cigarette of the day within 5 minutes of waking; 31 percent smoked within 6 to 30 minutes of waking; 18 percent smoked within 31 to 60 minutes of waking; and 19 percent smoked more than one hour after waking. In addition, the researchers found that the NNAL level in the participants' blood was correlated with the participants' age, the age they started smoking, their gender and whether or not another smoker lived in their home, among other factors.

The team published its results in the March 29 issue of the journal Cancer, Epidemiology, Biomarkers and Prevention.

"Most importantly, we found that NNAL level was highest among people who smoked the soonest upon waking, regardless of the frequency of smoking and other factors that predict NNAL concentrations," Branstetter said. "We believe these people who smoke sooner after waking inhale more deeply and more thoroughly, which could explain the higher levels of NNAL in their blood, as well as their higher risk of developing oral or lung cancer. As a result, time to first cigarette might be an important factor in the identification of high-risk smokers and in the development of interventions targeted toward early-morning smokers."

Visualized: step inside CERN's particle-detecting Compact Muon Solenoid

Visualized Step inside CERN's particle detecting Compact Muon Solenoid

It's spring maintenance time over at the Large Hadron Collider, and the folks at CERN have seen fit to crack open the Compact Muon Solenoid to get at some of its loose connectors. You see, after three years, 99-percent of the the lead tungstate-based electromagnetic calorimeter's channels are currently operational -- but its keepers think it can do better, working on a less than reliable connection that has the preshower down to a paltry 97-percent. Naturally, they've cracked the thing open and thankfully given us a peek inside the beast.

Marquette marches on with 71-61 win over Miami

WASHINGTON (AP) ? After sweating through a pair of edge-of-your-seat comebacks, Marquette's first Sweet 16 victory in a decade was as straight and smooth as the 15-foot step-back jumper that Vander Blue nailed at the end of the first half.

It helped that the Golden Eagles ran into an out-of-sorts Miami team that, in an echo of its bus ride to the Verizon Center, was able to make as much headway as a frustrated commuter in rush-hour traffic.

Marquette is in the Elite Eight for the first time since 2003, getting there with an emphatic 71-61 win over Miami on Thursday night. The Golden Eagles were never threatened after taking a double-digit lead in the first half, quite the contrast from their rallies that beat Davidson by one and Butler by two earlier in the NCAA tournament.

"It's fantastic. It feels good not to have to worry about, are you going to lose on a last-second shot or are you going to win on a last-second shot?" said Jamil Wilson, who had 16 points and eight rebounds. "To have a cushion like that, these guys played with tremendous heart, and we did it all game."

Blue, who made the shot that beat Davidson and led the comeback against Butler, finished with 14 points. He wasn't Marquette's leading scorer, but his offensive and defensive energy pushed the Golden Eagles to a big lead early. It's a good thing he got his buzzer-beater before halftime ? for a change, Marquette didn't need one at the end of the game.

"We're so used to people not giving us credit. ... That fuels our fire," Blue said.

The third-seeded Golden Eagles (26-8) will face Big East rival Syracuse, the No. 4 seed, in the East Regional final on Saturday, aiming for a spot in the Final Foul for the first time since the 2003 team led by current Miami Heat star Dwyane Wade. Marquette was knocked out in the round of 16 the past two years.

"after 3 tries in the sweet 16 we finally figured it out. Congrts," Wade tweeted after the game.

Syracuse beat top-seeded Indiana 61-50 in the other East Regional semifinal.

This one wasn't hard to decipher. Marquette could shoot; Miami couldn't. The Hurricanes (29-7) had sentiment on their side, returning to the arena where coach Jim Larranaga led mid-major George Mason to the Final Four seven years ago, but they made only 35 percent of their field goals and missed 18 of 26 3-pointers.

"You ever have days where you're just out of sync or things just don't run along smoothly?" Larranaga said. "Almost like our trip over here. Our hotel is a mile and a half, it took us 45 minutes to get here. We had to go on nine different streets, weaving our way in and out of traffic and everything. And that's the way it seemed on the court. We were trying to find our way and never could. Never could get in rhythm offensively, and defensively. I don't think we communicated like we have been doing all season long."

Shane Larkin scored 14 points to lead the No. 2 seed Hurricanes, whose NCAA run to the round of 16 matched the best in school history.

"I think what we did this year was lay a foundation of what the program could be like," Larranaga said. "We're not anywhere near where I would like to be."

Marquette, meanwhile, shot 54 percent, a stark turnaround from its 38 percent rate from the first two games in the tournament. Davante Gardner added 14 points, with 12 coming in the second half when the Golden Eagles were comfortably ahead.

Comfortable being a relative term. Coach Buzz Williams, who relishes the Golden Eagles' underdog status, hardly seemed to know how to take such an easy win. He didn't look or sound like a winning coach afterward.

"Because of my path to this point, I do have an edge, and I probably need to have better wisdom as to how to handle that edge," Williams said. "But it's really delicate because our edge is why we win."

Blue got going when he picked off a pass and converted the steal into a one-handed jam to give Marquette an 8-4 lead. His running one-hander made it 12-4. Blue and Junior Cadougan forced a steal, getting Larkin to commit his second foul in the process.

Blue ended the half with an exclamation point, hitting the jumper just before the horn to give Marquette a 29-16 lead at the break. He drained the shot, strutted backward downcourt, cocked his right arm and gave Wilson a chest bump.

Meanwhile, the Hurricanes couldn't sink anything. They started 2 for 12, including 0 for 6 from 3-point range, and Larkin's 3-pointer more than 11 minutes into the game was the first Hurricanes field goal scored by anyone other than Kenny Kadji.

In the second half, Blue's basket with 10:03 to play gave Marquette a 51-30 lead. The Hurricanes, who by then had started to press full court, then put together their best sequence of the night, a 7-0 run that cut the lead to 14 with 8? minutes left.

But Wilson's dunk and Gardner's inside basket stretched the lead back to 18. Gardner became the scene-stealer late, thumping his chest to the Marquette fans after a dunk in the final four minutes.

The Hurricanes played without backup center Reggie Johnson, who had surgery Tuesday for a minor knee injury. Johnson was averaging seven rebounds, but he would have helped only if he could've put the ball in the basket.

"There are only two things you have to do in basketball ? one, put the ball in the basket, two, stop the other team from putting the ball in the basket. We weren't able to do either," Larranaga said.

What the justices said?and how often

By Simon Evans MEXICO CITY, March 27 (Reuters) - United States central defenders Omar Gonzalez and Matt Besler went into Tuesday's game against Mexico at the Azteca Stadium with just two World Cup qualifying starts between them, but looked like they had been alongside each other for years in a spirited 0-0 draw. Gonzalez, making his third start in a qualifier and Besler making his first, held Mexico at bay in front of more than 95,000 fans as the U.S earned just their second point ever at the home of their arch-rivals. ...

'Gang of 8' senators see Border Patrol in action

Four of the U.S. senators leading the charge on immigration reform got more than they expected today when they came to Nogales, Ariz., to check on border security.

Just a few steps away from where they stood with Customs and Border Patrol officials, the problem facing the nation unfolded before their eyes: A young woman was sprinting her way out of Mexico, then climbing a security fence, only to be caught by the border patrol within seconds.

Sen. John McCain, R-Ariz., soon tweeted about the event, saying: "Just witnessed a woman successfully climb an 18-ft bollard fence a few yards from us in Nogales. And Border Patrol successfully apprehended her, but incident is another reminder that threats to our border security are real."

Arizona's Senate delegation, McCain and Sen. Jeff Flake, both Republicans, hosted Sen. Charles Schumer, D-N.Y., and Sen. Michael Bennet, D-Colo., for a tour along the border in Nogales, part of the Tucson sector. All four senators are members of the so-called "Gang of Eight" that is working on a solution to the nation's immigration issues.

ABC News was at the scene of the apprehension exclusively and later asked the senators from out of state what they thought of the experience.

"Well, I'd have to know all the details there to give you a judgment," Schumer said. "One of the things we learned is that a lot of people cross the border are doing it for drug purposes, too. But I don't know what happened in this situation."

The incident was "surprising" to Bennet.

"I just have never seen it before," he said.

For McCain, the incident was all-too-normal.

"One of the sad things about all of this is that most of those people who jump over the fence are doing that because they want a better life," he said at the news conference following the tour. "And I understand that. So we separate the drug cartels from individuals or somebody trying to cross over so they improve their lives."

The Border Patrol has more agents than ever, nearly 22,000, with 651 miles of fence along the 1,969-mile-long border.

Technology assists the boots on the ground, with 125 airplanes and six drones patrolling the Mexican frontier all working together to make crossing the border illegally more difficult than ever.

In fact, apprehensions like the ones the senators saw today are down 78 percent from their peak in 2000.

President Obama, in interviews with ABC News' partner, Univision, said today he thinks the border is secure enough to begin the reforms that would bring the 11 million undocumented immigrants out of the shadows.

"It's never going to be 110-percent perfect, but what we can do is to continue to improve it and, at the same time, provide a clear pathway for those who are already here and who've invested their lives here," the president said.

RELATED: President Obama Expects Immigration Bill in April

Counter to stereotype, six of the nation's 10 safest cities are on or near the border. El Paso, Texas, which sits just a few miles from Juarez, Mexico, has the lowest crime rate in the nation three years running.

El Paso Mayor John Cook said it's time to start immigration reform now "because [the] border is secure."

RELATED: 'Gang of Eight' to Tour Arizona-Mexico Border

"For the most part, people who come into the United States don't want to get in trouble. They don't want to commit crimes," he said. "They just want to make a living. I call them economic refugees [because] they just came to try to secure the American dream and a better life for their families, not to commit crimes."

Back in Arizona, McCain was in his home state to convince skeptics from his base that border security is improving. He gave this qualified endorsement.

"With the proper use of technology, with the proper coordination between different agencies, [I believe] that we will be able to say that we have a degree of border security that would allow people to move forward to a path of citizenship," McCain said.

The senators said they hope to have an agreement on an immigration reform bill soon.

"We hope to have a bill agreed to and done the day we come back," Schumer said.

Both McCain and Schumer recognized that compromise was key.

"With this legislation, no one will be totally happy because we are having to make compromises, and that's what makes for good legislation, is compromise that brings everybody together," McCain said.

They added that the reforms cannot be passed piecemeal and will need to be passed as a complete unit.

The four senators who did not make the tour hope to make one in the near future. They already had plans for the recess when it was organized.

(AP Photo/Carolyn Kaster)

(AP) ? In a major gay rights case, the Supreme Court indicated Wednesday it could strike down the law that prevents legally married gay couples from receiving a range of federal benefits that go to other married people.

Justice Anthony Kennedy, often the decisive vote in close cases, joined the four more liberal justices in raising questions about a provision of the federal Defense of Marriage Act that is being challenged at the court.

Kennedy said the law appears to intrude on the power of states that have chosen to recognize same-sex marriages. Other justices said the law creates what Justice Ruth Bader Ginsburg called two classes of marriage, full and "skim-milk marriage."

The federal law affects a range of benefits available to married couples, including tax breaks, survivor benefits and health insurance for spouses of federal employees.

It still is possible the court could dismiss the case for procedural reasons, though that prospect seemed less likely than it did in Tuesday's argument over gay marriage in California.

The motivation behind the 1996 federal law, passed by large majorities in Congress and signed by President Bill Clinton, was questioned repeatedly by Justice Elena Kagan.

She read from a House of Representatives report explaining that the reason for the law was "to express moral disapproval of homosexuality." The quote produced an audible reaction in the courtroom.

Paul Clement, representing the House Republican leadership in defending the law, said the more relevant question is whether Congress had "any rational basis for the statute." He supplied one, the federal government's interest in treating same-sex couples the same no matter where they live.

Clement said the government does not want military families "to resist transfer from West Point to Fort Sill because they're going to lose their benefits." The U.S. Military Academy at West Point is in New York, where same-sex marriage is legal, and Fort Sill is in Oklahoma, where gay marriages are not legal.

Opposing Clement was the Obama administration's top Supreme Court lawyer, Donald Verrilli, who said the provision of DOMA at issue, Section 3, impermissibly discriminates against gay people.

"This statute is not called the Federal Uniform Benefits Act," Verrilli said. The administration wants the court to apply a level of scrutiny it applies to discrimination against other disadvantaged groups and that makes it harder for governments to justify those laws.

Both Verrilli and Roberta Kaplan, the lawyer for the 83-year-old New Yorker who sued over DOMA, told the court that views about gay people and marriage have shifted dramatically since 1996.

"Why are you so confident in that judgment? How many states" allow same-sex unions? Justice Antonin Scalia asked Kaplan.

Nine, she said.

"So there's been a sea change since 1996," Scalia said, doubtfully.

But Chief Justice John Roberts jumped on the idea of a rapid shift in opinion to suggest that perhaps gays and lesbians do not need special protection from the court.

"As far as I can tell, political leaders are falling all over themselves to endorse your side of the case," Roberts said.

The justices stepped into the dispute after lower federal courts ruled against the measure.

The DOMA argument followed Tuesday's case over California's ban on same-sex marriage, a case in which the justices indicated they might avoid a major national ruling on whether America's gays and lesbians have a right to marry. Even without a significant ruling, the court appeared headed for a resolution that would mean the resumption of gay and lesbian weddings in California.

Marital status is relevant in more than 1,100 federal laws that include estate taxes, Social Security survivor benefits and health benefits for federal employees. Lawsuits around the country have led four federal district courts and two appeals courts to strike down the law's Section 3, which defines marriage. In 2011, the Obama administration abandoned its defense of the law but continues to enforce it.

Same-sex marriage is legal in nine states and the District of Columbia. The states are Connecticut, Iowa, Maine, Maryland, Massachusetts, New Hampshire, New York, Vermont and Washington. It was legal in California for less than five months in 2008.

The justices chose for their review the case of Edith Windsor, 83, of New York, who sued to challenge a $363,000 federal estate tax bill after her partner of 44 years died in 2009.

Windsor, who goes by Edie, married Thea Spyer in 2007 in Canada after doctors told them that Spyer would not live much longer. She suffered from multiple sclerosis for many years. Spyer left everything she had to Windsor.

There is no dispute that if Windsor had been married to a man, her estate tax bill would have been zero.

The U.S. 2nd Circuit Court of Appeals in New York agreed with a district judge that the provision of DOMA deprived Windsor of the constitutional guarantee of equal protection of the law.

Like the Proposition 8 case from California, Windsor's lawsuit could falter on a legal technicality without a definitive ruling from the high court.

The House Republicans, the Obama administration and a lawyer appointed by the court especially to argue the issue spent the first 50 minutes Wednesday discussing whether the House Republican leadership can defend the law in court because the administration decided not to, and whether the administration forfeited its right to participate in the case because it changed its position and now argues that the provision is unconstitutional.

If the Supreme Court finds that it does not have the authority to hear the case, Windsor probably would still get her refund because she won in the lower courts. But there would be no definitive decision about the law from the nation's highest court, and it would remain on the books.

Roberts and Scalia seemed most interested in this sort of outcome.

On Tuesday, the justices weighed a fundamental issue: Does the Constitution require that people be allowed to marry whom they choose, regardless of either partner's gender? The fact that the question was in front of the Supreme Court at all was startling, given that no state recognized same-sex unions before 2003 and 40 states still don't allow them.

But it was clear from the start of that argument in a packed courtroom that the justices, including some liberals who seemed open to gay marriage, had doubts about whether they should even be hearing the challenge to California's Proposition 8, the state's voter-approved gay marriage ban.

Kennedy suggested the justices could dismiss the case with no ruling at all.

Such an outcome would almost certainly allow gay marriages to resume in California but would have no impact elsewhere.

There was no majority apparent for any particular outcome, and many doubts were expressed by justices about the arguments advanced by lawyers for the opponents of gay marriage in California, by the supporters and by the Obama administration, which is in favor of same-sex marriage rights. The administration's entry into the case followed President Barack Obama's declaration of support for gay marriage.

Reflecting the high interest in the cases, the court released an audio recording of Wednesday's argument, just as it did Tuesday.

Wednesday's audio can be found at: http://tinyurl.com/d626ybg ; Tuesday's at: http://tinyurl.com/dxefy2a.

A somewhat smaller crowd gathered outside the court Wednesday, mainly gay marriage supporters who held American and rainbow flags. "Two, four, six, eight, we do not discriminate," a group chanted at one point. "If this isn't the time, when is the time? When does equality come into play?" asked Laura Scott, 43, of Columbia, Md.

Artifacts shed light on social networks of the past

Mar. 25, 2013 ? Researchers studied thousands of ceramic and obsidian artifacts from A.D. 1200-1450 to learn about the growth, collapse and change of social networks in the late pre-Hispanic Southwest.

The advent of social networking sites like Facebook and Twitter have made us all more connected, but long-distance social networks existed long before the Internet.

An article published this week in the Proceedings of the National Academy of Sciences sheds light on the transformation of social networks in the late pre-Hispanic American Southwest and shows that people of that period were able to maintain surprisingly long-distance relationships with nothing more than their feet to connect them.

Led by University of Arizona anthropologist Barbara Mills, the study is based on analysis of more than 800,000 painted ceramic and more than 4,800 obsidian artifacts dating from A.D. 1200-1450, uncovered from more than 700 sites in the western Southwest, in what is now Arizona and western New Mexico.

With funding from the National Science Foundation, Mills, director of the UA School of Anthropology, worked with collaborators at Archeology Southwest in Tucson to compile a database of more than 4.3 million ceramic artifacts and more than 4,800 obsidian artifacts, from which they drew for the study.

They then applied formal social network analysis to see what material culture could teach them about how social networks shifted and evolved during a period that saw large-scale demographic changes, including long-distance migration and coalescence of populations into large villages.

Their findings illustrate dramatic changes in social networks in the Southwest over the 250-year period between A.D. 1200 and 1450. They found, for example, that while a large social network in the southern part of the Southwest grew very large and then collapsed, networks in the northern part of the Southwest became more fragmented but persisted over time.

"Network scientists often talk about how increasingly connected networks become, or the 'small world' effect, but our study shows that this isn't always the case," said Mills, who led the study with co-principal investigator and UA alumnus Jeffery Clark, of Archaeology Southwest.

"Our long-term study shows that there are cycles of growth and collapse in social networks when we look at them over centuries," Mills said. "Highly connected worlds can become highly fragmented."

Another important finding was that early social networks do not appear to have been as restricted as expected by settlements' physical distance from one another. Researchers found that similar types of painted pottery were being created and used in villages as far as 250 kilometers apart, suggesting people were maintaining relationships across relatively large geographic expanses, despite the only mode of transportation being walking.

"They were making, using and discarding very similar kinds of assemblages over these very large spaces, which means that a lot of their daily practices were the same," Mills said. "That doesn't come about by chance; it has to come about by interaction -- the kind of interaction where it's not just a simple exchange but where people are learning how to make and how to use and ultimately discard different kinds of pottery."

"That really shocked us, this idea that you can have such long distance connections. In the pre-Hispanic Southwest they had no real vehicles, they had no beasts of burden, so they had to share information by walking," she said.

The application of formal social network analysis -- which focuses on the relationships among nodes, such as individuals, household or settlements -- is relatively new in the field of archaeology, which has traditionally focused more on specific attributes of those nodes, such as their size or function.

The UA study shows how social network analysis can be applied to a database of material culture to illustrate changes in network structures over time.

"We already knew about demographic changes -- where people were living and where migration was happening -- but what we didn't know was how that changed social networks," Mills said. "We're so used to looking traditionally at distributions of pottery and other objects based on their occurrence in space, but to see how social relationships are created out of these distributions is what network analysis can help with."

One of Mills's collaborators on the project was Ronald Breiger, renowned network analysis expert and a UA professor of sociology, with affiliations in statistics and government and public policy, who says being able to apply network analysis to archaeology has important implications for his field.

"Barbara (Mills) and her group are pioneers in bringing the social network perspective to archaeology and into ancient societies," said Breiger, who worked with Mills along with collaborators from the UA School of Anthropology; Archaeology Southwest; the University of Wisconsin, Milwaukee; Hendrix College; the University of Colorado, Boulder; the Santa Fe Institute; and Archaeological XRF Laboratory in Albuquerque, N.M.

"What archaeology has to offer for a study of networks is a focus on very long-term dynamics and applications to societies that aren't necessarily Western, so that's broadening to the community of social network researchers," Breiger said. "The coming together of social network and spatial analysis and the use of material objects to talk about culture is very much at the forefront of where I see the field of social network analysis moving."

Going forward, Mills hopes to use the same types of analyses to study even older social networks.

"We have a basis for building on, and we're hoping to get even greater time depth. We'd like to extend it back in time 400 years earlier," she said. "The implications are we can see things at a spatial scale that we've never been able to look at before in a systematic way. It changes our picture of the Southwest."

Swedish scientist to head U.N. Syria chemical weapons probe

By Louis Charbonneau and Michelle Nichols

UNITED NATIONS (Reuters) - U.N. Secretary-General Ban Ki-moon has named Swedish scientist Ake Sellstrom to head a U.N. investigation into allegations that chemical weapons were used in Syria, Ban's spokesman said on Tuesday.

"He is an accomplished scientist with a solid background in disarmament and international security," U.N. spokesman Martin Nesirky said.

The United Nations said last week it would investigate Syrian allegations that rebels used chemical arms in an attack near the northern city of Aleppo, but Western countries sought a probe of all claims about the use of such arms, including rebel charges that government forces used them.

If an investigation adds credibility to the rebels' claims that the government has used chemical weapons, it would represent another blow to Bashar al-Assad's efforts to retain power. If it turned out the rebels have used them, it could make countries even more reluctant to support the opposition.

It was not immediately clear who else would be on Sellstrom's team. Russia said on Monday that Russian and Chinese experts should be part of the investigation, but Moscow's U.N. Ambassador Vitaly Churkin said on Tuesday that Russia would "most likely not" be represented.

Sellstrom was a chief inspector for UNSCOM, the U.N. inspection team that investigated and dismantled Iraq's biological and chemical weapons programs in the 1990s.

Sellstrom also worked with UNMOVIC, the U.N. group that returned to Iraq in 2002 and found no solid evidence that Baghdad had revived its weapons-of-mass-destruction programs before the 2003 U.S.-led invasion as Washington and London alleged at the time.

Nesirky said Sellstrom's investigation would be a technical, not a criminal, investigation, looking at whether chemical weapons were used and not at who may have used them.

U.S. and European officials say there is no evidence of a chemical weapons attack, but the allegations of the rebels are worth taking seriously. If one were to be confirmed, it would be the first use of such weapons in the two-year-old Syrian conflict, which the United Nations says has cost 70,000 lives.

France and Britain wrote to Ban on Thursday to draw his attention to rebel allegations of an attack near Damascus, as well as one in Homs in late December. The rebels blame Syria's government for those incidents as well as the Aleppo attack.

EXPANDING THE INVESTIGATION?

Ban made clear on Thursday that the investigation would initially focus on the Aleppo incident, in which the government and rebels accuse each other of firing a missile laden with chemicals, killing 26 people.

But he has left open the possibility that the investigation could be broadened. In a letter to the Security Council on Friday, Ban said he had asked Britain, France and Syria for further information on the other alleged chemical attacks "with a view to verifying any alleged use of chemical weapons in Syria."

Britain's U.N. Ambassador Mark Lyall Grant told reporters on Tuesday that he has provided Ban's office with "further information" about the alleged chemical attacks in Syria. He declined to provide details.

The suggestion that the investigation may go beyond the Aleppo attack has infuriated Russia. Security Council diplomats told Reuters on condition of anonymity that the Russian U.N. mission went so far as to ask Ban to withdraw his Friday letter.

Russia's U.N. mission had no response on Monday when asked to comment on the alleged request that Ban withdraw his letter. Russian Ambassador Vitaly Churkin said on Monday that the Anglo-French call for a broader investigation was an attempt to "delay and possibly derail" the U.N. probe.

Russia has criticized Western and Arab calls for Assad to leave power and, together with China, has blocked three U.N. Security Council resolutions meant to pressure him to end violence. It has also differed with the West over which side was to blame for alleged massacres and other atrocities in Syria.

A member of the Syrian opposition said Sellstrom's investigation would not be hindered by the rebels.

"We can guarantee him (Sellstrom) safe passage in the areas where the incidents took place in northern Syria," Wael Merza, an adviser to the Syrian coalition's new interim Prime Minister Ghassan Hitto, told Reuters on sidelines of an Arab summit in Doha.

Merza said there were at least two known cases where they suspect chemical weapons were used by forces loyal to Assad.
