Wall Street flat after durable goods; Boeing supports

By Chuck Mikolajczak

NEW YORK (Reuters) - Stocks were little changed on Wednesday, after a disappointing durable goods report tempered recent enthusiasm over a relatively robust earnings season.

Economic data showed orders for long-lasting U.S. manufactured goods slumped 5.7 percent in March, the biggest drop in seven months, and far below expectations calling for a decline of 2.8 percent.

"It's basically just confirming what we've seen in the economic numbers so far this month, that basically, things weren't quite as good as we thought at the end of the first quarter," said Peter Jankovskis, co-chief investment officer at OakBrook Investments LLC in Lisle, Illinois.

"I don't expect there to be a massive selloff today but (the data) says the economy is having to work pretty hard to make progress."

But support for the Dow and S&P was provided Boeing Co , which jumped 4.2 percent to $91.92 as the top boost for each index after the aerospace giant reported first-quarter earnings.

Also offsetting results from Boeing were declines in Procter and Gamble Co , which lost 4.2 percent to $78.47 after reporting third-quarter results and issuing a profit outlook for the current quarter that fell short of Wall Street's expectations. The S&P consumer staples index <.splrcs> shed 0.5 percent.

Corning Inc gained 4 percent to $13.66 after the specialty glass maker's first-quarter profit beat analysts' estimates, helped by strong demand for its scratch-resistant Gorilla Glass used in smartphones and tablets.

According to Thomson Reuters data, 45 companies in the S&P 500 <.spx> are scheduled to report results Wednesday, including Dow component Aflac Inc , Qualcomm Inc and Citrix Systems Inc after the close.

Apple Inc shares lost 0.8 percent to $402.95 after the iPad maker bowed Tuesday to investors' demands to share more of its $145 billion cash pile, while posting its first quarterly profit decline in more than a decade.

The Dow Jones industrial average <.dji> dropped 2.30 points, or 0.02 percent, to 14,717.16. The Standard & Poor's 500 Index <.spx> gained 1.00 points, or 0.06 percent, to 1,579.78. The Nasdaq Composite Index <.ixic> slipped 1.57 points, or 0.05 percent, to 3,267.76.

Earnings season has been largely positive, with more than 68.9 percent of S&P 500 companies that have reported results so far beating expectations, according to Thomson Reuters data through Tuesday morning. Since 1994, 63 percent have surpassed estimates on average, while the beat rate is 67 percent for the past four quarters.

Analysts see earnings growth of 2.3 percent this quarter, up from expectations of 1.5 percent at the start of the month.

In merger news, OPKO Health Inc will buy Israel-based biopharmaceutical company Prolor Biotech Inc in an all-stock deal valued at $480 million to expand its portfolio of specialty drugs. OPKO shares dipped 1.6 percent to $6.95 while Prolor jumped 8.2 percent to $6.31.

'DWTS' destiny: Ortiz knew he was out

By Michael Maloney, TODAY contributor

Craig Sjodin / ABC

Victor Ortiz and his "Dancing With the Stars" pro partner Lindsay Arnold.

Former welterweight boxing champ Victor Ortiz knew he?d danced his last routine on "Dancing With the Stars" after performing a disappointing rumba with pro partner Lindsay Arnold on Monday night.

?My performance didn?t come through as it had in rehearsal,? Ortiz candidly shared with reporters after being eliminated Tuesday. "I accepted on Monday that we?d be eliminated.?

Ortiz said he doesn?t regret his "Dancing" run -- which included the video package that showed him opening up about a failed relationship. ?I don?t take any of this experience back,? he said. ?I loved every minute of it. I?m still winning because I made some great friends, and (met) a great gal, too. I?ll always be a fan of Miss Lindsay.?

Arnold, like other ejected pros, will return for results show performances. She also hopes to return next season with another star.

?I grew so much this season,? she said.

Meanwhile, Ortiz already has plans to return to the ring. ?I made a call a few weeks back because I had a feeling I?d be eliminated soon,? he revealed. ?I notified my management to get me a fight. I?ll be fighting again in the next couple of months for a world championship.?

Arnold and Ortiz will take to the dance floor one more time when all the ejected couples return for the season finale in May. While some eliminated stars don?t relish that thought, it?s actually fine with Ortiz. ?

?That?ll work to my advantage,? he said. ?I?ll have a break to do my thing for a while and then I?ll come back and say, ?Let?s charge at this!??

The crystal's corners: New nanowire structure has potential to increase semiconductor applications

Apr. 23, 2013 ? There's big news in the world of tiny things. New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with something that's 1,000 times thinner than the typical human hair -- a semiconductor nanowire.

UC's Jackson, Smith, recently graduated PhD student Melodie Fickenscher and physics doctoral student Teng Shi, as well as several colleagues from across the US and around the world recently have published the research paper "Optical, Structural and Numerical Investigations of GaAs/AlGaAs Core-Multishell Nanowire Quantum Well Tubes" in Nano Letters, a journal on nanoscience and nanotechnology published by the American Chemical Society. In the paper, the team reports that they've discovered a new structure in a semiconductor nanowire with unique properties.

"This kind of structure in the gallium arsenide/aluminum gallium arsenide system had not been achieved before," Jackson says. "It's new in terms of where you find the electrons and holes, and spatially it's a new structure."

EYES ON SIZE AND CORNERING ELECTRONS

These little structures could have a big effect on a variety of technologies. Semiconductors are at the center of modern electronics. Computers, TVs and cellphones have them. They're made from the crystalline form of elements that have scientifically beneficial electrical conductivity properties. Many semiconductors are made of silicon, but in this case they are made of gallium arsenide. And while widespread use of these thin nanowires in new devices might still be around the corner, the key to making that outcome a reality in the coming years is what's in the corner.

By using a thin shell called a quantum well tube and growing it -- to about 4 nanometers thick -- around the nanowire core, the researchers found electrons within the nanowire were distributed in an unusual way in relation to the facets of the hexagonal tube. A close look at the corners of the tube's facets revealed something unexpected -- a high concentration of ground state electrons and holes.

"Having the faceting really matters. It changes the ballgame," Jackson says. "Adjusting the quantum well tube width allows you to control the energy -- which would have been expected -- but in addition we have found that there's a highly localized ground state at the corners which then can give rise to true quantum nanowires."

The nanowires the team uses for its research are grown at the Australian National University in Canberra, Australia -- one partner in this project that extends to disparate parts of the globe.

AFFECTING THE SCIENCE OF SMALL IN A BIG WAY

The team's discovery opens a new door to further study of the fundamental physics of semiconductor nanowires. As for leading to advances in technology such as photovoltaic cells, Jackson says it's too soon to tell because quantum nanowires are just now being explored. But in a world where hundreds of dollars' worth of technology is packed into a 5-by-2.5 inch iPhone, it's not hard to see how small but powerful science comes at a premium.

The team at UC is one of only about a half dozen in the US conducting competitive research in the field. It's a relatively young discipline, too, Jackson says, and one that's moving fast. For such innovative science, he says it's important to have a collaborative effort. The team includes scientists from research centers in the Midwest, the West Coast and all the way Down Under: UC, Miami University of Ohio and Sandia National Laboratories in California here in the US; and Monash University and the Australian National University in Australia.

The team's efforts are another example of how UC not only stands out as a leader in top-notch science, but also in shaping the future of the discipline by providing its students with high-quality educational and research opportunities.

"We're training students in state-of-the-art techniques on state-of-the-art materials doing state-of-the-art physics," Jackson says. "Upon completing their education here, they're positioned to go out and make contributions of their own."

(AP) ? The minaret of a landmark 12th century mosque in the northern Syrian city of Aleppo was destroyed Wednesday, leaving the once-soaring stone tower a pile of rubble and twisted metal scattered in the tiled courtyard.

President Bashar Assad's regime and anti-government activists traded blame for the destruction to the Umayyad Mosque, which occurred in the heart Aleppo's walled Old City, a UNESCO World Heritage site.

It was the second time in just over a week that a historic Sunni mosque in Syria has been seriously damaged. Mosques served as a launching pad for anti-government protests in the early days of the country's 2-year-old uprising, and many have been targeted.

Syrian's state news agency SANA said rebels from the al-Qaida-linked Jabhat al-Nusra group blew it up, while Aleppo-based activist Mohammed al-Khatib said a Syrian army tank fired a shell that "totally destroyed" the minaret.

The mosque fell into rebel hands earlier this year after heavy fighting that damaged the historic compound. The area around it, however, remains contested. Syrian troops are about 200 meters (yards) away.

An amateur video posted online by the anti-government Aleppo Media Center activist group showed the mosque's archways, charred from earlier fighting, and a pile of rubble where the minaret used to be.

Standing inside the mosque's courtyard, a man who appears to be a rebel fighter says regime forces recently fired seven shells at the minaret but failed to knock it down. He said that on Wednesday the tank rounds struck their target.

"We were standing here today and suddenly shells started hitting the minaret," the man says. "They (the army) then tried to storm the mosque but we pushed them back."

The video appeared genuine and corresponded to other Associated Press reporting of the events depicted.

The destruction in Aleppo follows a similar incident in the southern city of Daraa, where the minaret of the historic Omari Mosque was destroyed more than a week ago. The Daraa mosque was built during the Islamic conquest of Syria in the days of Caliph Omar ibn al-Khattab in the seventh century.

In that instance as well, the opposition and regime blamed each other for the damage. SANA also accused Jabhat al-Nusra of positioning cameras around the area to record the event in that case.

Syria's civil war, with the use of everything from small arms to artillery and warplanes, poses a grave threat to the country's rich cultural heritage.

Last year, the medieval market in Aleppo, which is located near the Umayyad Mosque, was gutted by fire sparked by fighting last year.

Both rebels and regime forces have turned some of Syria's significant historic sites into bases, including citadels and Turkish bath houses, while thieves have stolen artifacts from museums.

Five of Syria's six World Heritage sites have been damaged in the fighting, according to UNESCO, the U.N.'s cultural agency. Looters have broken into one of the world's best-preserved Crusader castles, Crac des Chevaliers, and ruins in the ancient city of Palmyra have been damaged.

The damage is just part of the wider devastation caused by the country's crisis, which began more than two years ago with largely peaceful protests but morphed into a civil war as the opposition took up arms in the face of a withering government crackdown. The fighting has exacted a huge toll on the country, killing more than 70,000 people, laying waste to cities, towns and villages and forcing more than a million people to flee their homes and seek refuge abroad.

Aleppo, the country's largest city, and Damascus are two of the key fronts in the conflict, which pits the an Assad regime dominated by the president's Alawite sect, an offshoot of Shiite Islam, and a rebel movement drawn primarily from Syria's Sunni Muslim majority.

Aleppo has been carved into rebel- and regime-held zones, while Damascus remains firmly in government hands, although the rebels have established a foothold in the suburbs and hope to use their enclaves there to eventually push into the city itself.

On Wednesday, two mortar rounds slammed into the Damascus suburb of Jaramana, killing at least seven people and wounding dozens, state media and activists said.

The Britain-based Syrian Observatory for Human Rights said the shells hit near a municipality building and a school in Jaramana. The Observatory, which relies on reports from a network of activists on the ground, said 10 people were killed and 30 were wounded in the attacks.

Syrian state-run SANA news agency said seven people were killed in the attack.

The differences in the death tolls could not be immediately reconciled.

Also Wednesday, Syrian church officials said the whereabouts of two bishops kidnapped in northern Syria remain unknown, a day after telling reporters the priests had been released.

Bishop Tony Yazigi of the Damascus-based Greek Orthodox Church said Tuesday that the bishops, both of whom are based in the northern city of Aleppo, had been released. But later on Tuesday, the Syrian Orthodox Patriarchate in the capital said in a statement on its website that it had not received "any official document indicating the (bishops') release."

Gunmen pulled Bishop Boulos Yazigi of the Greek Orthodox Church and Bishop John Ibrahim of the Assyrian Orthodox Church from their car and killed their driver on Monday while they were traveling outside Aleppo. It was not clear who abducted the priests.

But Bishop Yazigi, who is the brother on one of the abductees, said the gunmen are believed to be Chechen fighters from Jabhat al-Nusra group, one of the most powerful of the myriad of rebel factions fighting in Syria. Yazigi declined to say what made it appear that the Nusra Front was involved.

That account corresponded to one provided by the Observatory, which said foreign fighters had abducted the bishops near a checkpoint outside Aleppo. Observatory director Rami Abdul-Rahman said Wednesday that activists in the area where the kidnapping took place say the gunmen were foreign fighters from the Caucuses.

However, the main opposition group, the Syrian National Coalition, condemned the kidnapping and blamed Assad's regime.

In Rome, Pope Francis called for the rapid release of the two bishops. In his appeal Tuesday, the pontiff called the abduction "a dramatic confirmation of the tragic situation in which the Syrian population and its Christian community is living."

There has been a spike in kidnappings in northern Syria, much of which is controlled by the rebels, and around Damascus in recent months. Residents blame criminal groups that have ties to both the regime and the rebels for the abductions of wealthy residents traveling to Syria from neighboring Turkey and Lebanon.
