US Airways CEO hoping for furlough resolution soon

By Karen Jacobs

SCOTTSDALE, Arizona (Reuters) - US Airways Group Chairman and Chief Executive Doug Parker said he was hopeful government leaders would come to a solution that would halt the travel disruptions in wake of U.S. staff cuts of air traffic controllers.

"It's untenable as it is," Parker said in an interview on Wednesday in Scottsdale, Arizona, where US Airways held briefings with media.

"We can't do this for long without having major disruption to the flying public. And nobody wants that. We're highly hopeful something will get resolved soon."

U.S. air travelers have endured delays at some airports this week as furloughs of air traffic controllers started. Airlines have forecast hundreds of millions of dollars in lost revenue from the furloughs that have been imposed by the Federal Aviation Administration.

The FAA has outlined plans to idle 47,000 workers for up to 11 days through the end of September as part of its plan to meet required spending curbs. Nearly 13,000 of those staffers are air traffic controllers.

The airline industry has expressed concern that delays from the furloughs could depress travel as the critical summer season gets underway.

Parker said he spent a lot of his personal time in the past week calling government officials in his carrier's hub markets to stress the need to end the furloughs.

"Everyone understands the severity of the situation," Parker said. "Good-minded people are trying to figure out ways to stop it. We don't need finger-pointing, we need solutions."

US Airways plans to merge with American Airlines parent AMR Corp this year and form the world's biggest carrier. The company said on Wednesday it expected the combination to close by the end of September.

Parker will be chief executive of the new American Airlines once the merger closes. The $11 billion all-stock merger would finalize the consolidation of legacy U.S. airlines that has helped put the industry on more solid financial footing.

The tie-up would help US Airways and American better compete with United Continental Holdings and Delta Air Lines , both the products of mergers.

Internet sales tax bill advances in Senate

WASHINGTON (Reuters) - Wider U.S. tax collections on Internet sales moved another step closer to reality on Wednesday as legislation in the U.S. Senate cleared another procedural hurdle.

The 75-22 Senate vote cleared the way for consideration of a bill that would empower U.S. states to require out-of-state retailers to collect online sales taxes from customers.

A vote on passage of the measure could come this week.

Supporters include brick-and-mortar retailers such as Wal-Mart Stores Inc and Best Buy Co Inc, as well as cash-strapped state governments.

Amazon.com Inc, which hopes to simplify its U.S. state retail tax situation, also backs the legislation.

Opponents include many online merchants, including eBay Inc and Overstock.com Inc.

Prospects for passage are murky in the Republican-controlled House of Representatives, where some Republicans view it as a tax increase.

George leads Pacers past Hawks 113-98 for 2-0 lead

(AP) ? Paul George followed his triple-double by scoring a playoff career-high 27 points to lead Indiana past Atlanta 113-98 on Wednesday night.

The Pacers lead the best-of-seven first-round series 2-0 and have won four straight home games over the Hawks. It's the first time Indiana has held a 2-0 series lead since the 2004 Eastern Conference semifinals.

George, playing in his first game since being named the league's Most Improved Player, was 11 of 21 from the field, had eight rebounds, three assists and four steals and again played well defensively. George Hill had 22 points.

Atlanta was led by Devin Harris with 17 points. Jeff Teague and Josh Smith both had 16. The Hawks head home for Game 3 on Saturday.

Indiana again took control late in the first quarter and never trailed again.

The Hawks did play with more passion after being chastised by coach Larry Drew for not playing through calls and getting "manhandled" by the Pacers in Game 1.

The problem on Wednesday was that they got too aggressive at times. Josh Smith drew two fouls in the first 2 minutes and spent most of the game in foul trouble. An angry Al Horford charged toward an official in the second quarter after already picking up one technical and, fortunately for the Hawks, Harris grabbed Horford with two hands and pulled him away ? keeping Horford and the Hawks in the game. Atlanta's other big inside players, Johan Petro and Ivan Johnson got into foul trouble in the second half, too.

It resulted in a second straight double-digit loss for the Hawks ? a game in which the Pacers produced their highest postseason point total since a 120-87 rout of the Los Angeles Lakers in the 2000 NBA Finals.

In many ways, Wednesday's game looked awfully similar to what happened Sunday.

After scoring the first six points in Game 1, Atlanta opened Wednesday's game with the first five points. Then, just like Sunday, the Pacers rallied to take the lead after one quarter and didn't allow the Hawks to catch up. Indiana extended its 25-19 lead to 59-50 at halftime and to 16 late in the third quarter.

The Hawks did get within 88-76 after three, then watched Indiana go on a 9-0 run midway through the fourth quarter to take a 104-85 lead with 5:41 to go and the Hawks never challenged again.

Notes: Injured Pacers guard Danny Granger presented his friend George with the NBA's Most Improved Player trophy at midcourt before tip-off. ... Indiana has lost 11 straight at Atlanta. ... Indiana lost starting guard Lance Stephenson late in the first quarter when he landed hard on his right hip after being called for a charge. He was diagnosed with a bruised right hip and did not return until the start of the second half. Hill, the Pacers' other starting guard, appeared to hurt his right elbow late. ... Indiana is 51 of 63 from the free-throw line over the first two games. Atlanta is just 18 of 34.

Bomb suspect influenced by mysterious radical

WASHINGTON (AP) ? In the years before the Boston Marathon bombings, Tamerlan Tsarnaev fell under the influence of a new friend, a Muslim convert who steered the religiously apathetic young man toward a strict strain of Islam, family members said.

Under the tutelage of a friend known to the Tsarnaev family only as Misha, Tamerlan gave up boxing and stopped studying music, his family said. He began opposing the wars in Afghanistan and Iraq. He turned to websites and literature claiming that the CIA was behind the terrorist attacks of Sept. 11, 2001, and Jews controlled the world.

"Somehow, he just took his brain," said Tamerlan's uncle, Ruslan Tsarni, who recalled conversations with Tamerlan's worried father about Misha's influence. Efforts over several days by The Associated Press to identify and interview Misha have been unsuccessful.

Tamerlan's relationship with Misha could be a clue in understanding the motives behind his religious transformation and, ultimately, the attack itself. Two U.S. officials say he had no tie to terrorist groups.

Throughout his religious makeover, Tamerlan maintained a strong influence over his siblings, including Dzhokhar, who investigators say carried out the deadly attack by his older brother's side, killing three and injuring 264 people.

"They all loved Tamerlan. He was the eldest one and he, in many ways, was the role model for his sisters and his brother," said Elmirza Khozhugov, 26, the ex-husband of Tamerlan's sister, Ailina. "You could always hear his younger brother and sisters say, 'Tamerlan said this,' and 'Tamerlan said that.' Dzhokhar loved him. He would do whatever Tamerlan would say.

"Even my ex-wife loved him so much and respected him so much," Khozhugov said. "I'd have arguments with her and if Tamerlan took my side, she would agree: 'OK, if Tamerlan said it.'"

Khozhugov said he was close to Tamerlan when he was married and they kept in touch for a while but drifted apart in the past two years or so. He spoke to the AP from his home in Almaty, Kazakhstan. A family member in the United States provided the contact information.

Tamerlan Tsarnaev was killed in a police shootout Friday. Dzhokhar Tsarnaev was charged Monday with using a weapon of mass destruction to kill, and he could face the death penalty if convicted.

"Of course I was shocked and surprised that he was Suspect No. 1," Khozhugov said, recalling the days after the bombing when the FBI identified Tamerlan as the primary suspect. "But after a few hours of thinking about it, I thought it could be possible that he did it."

Based on preliminary written interviews with Dzhokar in his hospital bed, U.S. officials believe the brothers were motivated by their religious views. It has not been clear, however, what those views were.

As authorities try to piece together that information, they are touching on a question asked after so many terrorist plots: What turns someone into a terrorist?

The brothers emigrated in 2002 or 2003 from Dagestan, a Russian republic that has become an epicenter of the Islamic insurgency that spilled over from the region of Chechnya.

They were raised in a home that followed Sunni Islam, the religion's largest sect. They were not regulars at the mosque and rarely discussed religion, Khozhugov said.

Then, in 2008 or 2009, Tamerlan met Misha, a slightly older, heavyset bald man with a long reddish beard. Khozhugov didn't know where they'd met but believed they attended a Boston-area mosque together. Misha was an Armenian native and a convert to Islam and quickly began influencing his new friend, family members said.

Once, Khozhugov said, Misha came to the family home outside Boston and sat in the kitchen, chatting with Tamerlan for hours.

"Misha was telling him what is Islam, what is good in Islam, what is bad in Islam," said Khozhugov, who said he was present for the conversation. "This is the best religion and that's it. Mohammed said this and Mohammed said that."

The conversation continued until Tamerlan's father, Anzor, came home from work.

"It was late, like midnight," Khozhugov said. "His father comes in and says, 'Why is Misha here so late and still in our house?' He asked it politely. Tamerlan was so much into the conversation he didn't listen."

Khozhugov said Tamerlan's mother, Zubeidat, told him not to worry.

"'Don't interrupt them,'" Khozhugov recalled the mother saying. "'They're talking about religion and good things. Misha is teaching him to be good and nice.'"

As time went on, Tamerlan and his father argued about the young man's new beliefs.

"When Misha would start talking, Tamerlan would stop talking and listen. It upset his father because Tamerlan wouldn't listen to him as much," Khozhugov said. "He would listen to this guy from the mosque who was preaching to him."

Anzor became so concerned that he called his brother, worried about Misha's effects.

"I heard about nobody else but this convert," Tsarni said. "The seed for changing his views was planted right there in Cambridge."

It was not immediately clear whether the FBI has spoken to Misha or was attempting to.

Tsarnaev became an ardent reader of jihadist websites and extremist propaganda, two U.S. officials said. He read Inspire magazine, an English-language online publication produced by al-Qaida's Yemen affiliate.

Tamerlan loved music and, a few years ago, he sent Khozhugov a song he'd composed in English and Russian. He said he was about to start music school.

Six weeks later, the two men spoke on the phone. Khozhugov asked how school was going.

"I quit," Tamerlan said.

"Why did you quit?" Khozhugov asked. "You just started."

"Music is not really supported in Islam," he replied.

"Who told you that?"

"Misha said it's not really good to create music. It's not really good to listen to music," Tamerlan said, according to Khozhugov.

Tamerlan took an interest in Infowars, a conspiracy theory website. Khozhugov said Tamerlan was interested in finding a copy of the book "The Protocols of the Elders of Zion," the classic anti-Semitic hoax, first published in Russia in 1903, that claims a Jewish plot to take over the world.

"He never said he hated America or he hated the Jews," Khozhugov said. "But he was fairly aggressive toward the policies of the U.S. toward countries with Muslim populations. He disliked the wars."

One of the brothers' neighbors, Albrecht Ammon, recently recalled an encounter in which Tamerlan argued about U.S. foreign policy, the wars in Afghanistan and Iraq, and religion.

Ammon said Tamerlan described the Bible as a "cheap copy" of the Quran, used to justify wars with other countries.

"He had nothing against the American people," Ammon said. "He had something against the American government."

Khozhugov said Tamerlan did not know much about Islam beyond what he found online or what he heard from Misha.

"Misha was important," he said. "Tamerlan was searching for something. He was searching for something out there."

3 Stacks Smoke and Tap House in Frisco, Texas treated doctors at Massachusetts General Hospital to a barbecue lunch, April 23, 2013, a thank-you for sending pizza and an encouraging note to Hillcrest Hospital, which treated 28 patients after the Texas fertilizer plant explosion. (Credit: Courtesy 3 Stacks Smoke and Tap House)

It all started when ?Dr. Chris Kabrhel, an emergency room physician??at Massachusetts General Hospital in Boston, ?sent pizza to the Hillcrest Hospital staff members in Waco, Texas, to thank them ?for their hard work after the fertilizer plant explosion that killed 14 people and injured hundreds of others 20 miles away in West, Texas.

Kabrhel sent the pizza to Texas Friday night even though his own hospital had received 29 Boston marathon bombing victims earlier in the week ?and were working ?with a smaller staff ?Friday because of the citywide lockdown that continued till the early evening.

?Thanks for all of your hard work,? the handwritten note says in black marker. ?From one member of the E. R. family, Chris Kabrhel?- Mass General Hospital.?

When Trace Arnold, who owns a newly opened?barbecue?joint, heard about it, he decided to return the favor ? Texas style.

?For the medical staff in Boston to be so thoughtful in the middle of their own city?s tragedy and think about us down here in Texas was just awesome,? Arnold said in a statement.

Courtesy of his new restaurant, 3 Stacks Smoke and Tap House in Frisco, Arnold flew about five coolers of ribs to MGH today. It arrived ?along with a giant, green Hillcrest Hospital flag that had been signed by 300 hospital employees offering words of encouragement.

?Literally, you can?t believe,? Dr. Paul Biddinger, who directs emergency operations at MGH, said as he spoke to ABCNews.com just before tucking into a plate of ribs. ?You can?t believe the smiles on our staff?s faces right now.?

Five ?bomb victims remain ?at MGH. Of the 28 patients admitted to Hillcrest Hospital on the Wednesday after the plant explosion, 24 have been discharged.

iPhone 5 vs. BlackBerry Q10: Which should you buy?

The BlackBerry Q10 represents the return of the original BlackBerry. And unabashedly so. Sure it runs the same BlackBerry 10 operating system as the full touchscreen BlackBerry Z10, but it packs it into the classic, keyboard package every hardcore communicator and enterprise accomplisher knows and loves. But how does it compare to the iPhone 5, and if you're considering both -- which one should you get?

And you know what? For what it is, it's really really good. I've been using BlackBerry 10 on the Z10 for a month or so, and I've been using Kevin Michaluk's BlackBerry Q10 review unit quite a bit this week. And the experience translates pretty well to the smaller 720x720 display on the Q10. The keyboard is everything you'd expect from the people who pretty much perfected it. It's a real BlackBerry in every way that matters.

On the other hand, the OLED display is sub-optimal and a compromise. It's a concession to battery life, which is the entire focus of a workhorse phone like the Q10. Apps are still sparse, and Android emulation is a stop-gap at best.

It's also a brand new OS, so while it has all the basics, and carries over a lot of the smart ideas from the Z10, but it's still first generation and that means it squeaks a little when it turns around too fast. But that's okay. Every modern mobile OS has been there.

The truth is, the Q10 is a hold-over from a time gone by, and hardware keyboards aren't a growth market anymore. Kids growing up today will be touch-screen native, and the Q10-style BlackBerry will fade as the Z10-style grows to take it's place.

But right now, today, I don't care. Right now, today, it's like watching your favorite hero from the past come out of retirement to kick ass one last time. And it's a hell of a thing to watch.

No one who wants an iPhone will want a Q10, but everyone who wants the BlackBerry will love it.

Go check out CrackBerry's coverage, then come back here and tell me what you think.

Some visible signs of Lyme disease are easily missed or mistaken

Apr. 22, 2013 ? When a person contracts Lyme disease, quick diagnosis and treatment are essential to avoiding long term complications. But the diagnostic process may be delayed if a physician does not recognize a skin rash caused by Lyme disease because it does not have the bull's-eye appearance that is best known to physicians and the public. In a Research Letter just published in the journal Emerging Infectious Diseases, a prominent research team led by Steven E, Schutzer, MD, Professor of Medicine at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School, confirms findings of Lyme disease in patients with skin lesions that more closely resemble the classic signs of conditions such as contact dermatitis, lupus, common skin infections, or insect or spider bites. Based on these findings they urge doctors to consider Lyme disease as the cause when presented with such lesions, particularly when the patient was in an area where Lyme disease is endemic.

The team describes 14 patients enrolled in an ongoing prospective trial which includes an advanced diagnostic technique that employs a selective "molecular culture-like" amplification of DNA from Borrelia burgdorferi, the bacterium that causes Lyme disease, followed by polymerase chain reaction (PCR) testing, all designed to detect even small numbers of multiple strains of the Lyme agent. The technique was first described in May 2012 in an article published in the journal PLoS One by a team that included several of the same researchers, including Schutzer. Unlike existing methods used to diagnose Lyme disease, the new experimental technique is able to detect evidence of B. burgdorferi early, even in cases where the bacterium is still at low levels in the bloodstream, and sooner than traditional antibody tests, which may require several weeks before becoming positive. It also is able to distinguish between new infections and prior exposure to B. burgdorferi.

Of the patients analyzed, ten found by the experimental technique to have strong microbiologic evidence of Lyme disease had presented with skin lesions that differed markedly from the classic bull's-eye pattern. The researchers note that multiple textbooks and websites prominently feature the bull's-eye image as a visual representation of Lyme disease. They write, "This emphasis on target-like lesions may have inadvertently contributed to an underappreciation for atypical skin lesions caused by Lyme disease."

Not all patients with Lyme disease will have a rash. Schutzer cautioned that "these studies are preliminary and the impetus for further investigation." However, based on this finding, Schutzer adds, "Doctors who see a rash in a patient who has been in an area where Lyme disease frequently occurs should be alert to the fact that the Lyme disease rash does not have to look like a bull's-eye, ring-within-a ring. The rash may look different. Doctors should search carefully both for other signs that might suggest Lyme disease, such as flu-like symptoms, and equally for signs that may point towards other conditions. Early diagnosis of most diseases gives the best chance for a cure. This is especially true for Lyme disease." Schutzer said.

"The ongoing work has the potential to improve clinical research in Lyme disease by objectively defining a group of patients who assuredly were infected with the Lyme disease bacterium," said Dr. James G. Krueger, Head of the Laboratory for Investigative Dermatology at The Rockefeller University and co-investigator.

In addition to Schutzer and Krueger, investigators are: Bernard W. Berger a prominent dermatologist in private practice in Southampton, N.Y.; Mark W. Eshoo and David J. Ecker of Ibis Biosciences, Inc., Carlsbad, Calif.; and John N. Aucott of Johns Hopkins University.

Funding for the cited study was provided in part by a grant from the National Institute of Allergy and Infectious Diseases, National Institutes of Health.

Boston Marathon bombing: what the suspects' arsenal reveals

The quality and quantity of the Boston bombing suspects' armaments suggest a future attack was planned, but don't answer the question of whether they had outside help.

By Mark Trumbull,?Staff writer / April 22, 2013

This combination of undated file photos show Boston Marathon boming suspects Tamerlan Tsarnaev (l.) and Dzhokhar Tsarnaev. The brothers allegedly used handguns and a rifle during their confrontation with police, but had no firearms registered with local authorities.

The Lowell Sun & Robin Young/AP

The alleged Boston Marathon bombers had an arsenal of weapons that went beyond the explosive devices used at the marathon ? and which could have been intended for use in subsequent terror attacks.

That?s the picture that has been emerging from law enforcement officials one week after the deadly attack at Boston?s marathon finish line.

A criminal complaint against Dzhokhar Tsarnaev, filed Monday as he was being cared for at a Boston hospital, allege that he and his brother, now dead, wielded guns and numerous explosives as they were being pursued by police days after the initial bomb attacks.

"We have reason to believe, based upon the evidence that was found at that scene ? the explosions, the explosive ordnance that was unexploded and the firepower that they had ? that they were going to attack other individuals," Boston Police Commissioner Edward Davis said in an interview on CBS News Sunday. "That's my belief at this point.?

The brothers allegedly used handguns and a rifle during their confrontation with police, but had no firearms registered with local authorities. The New York Times identified the rifle as an M-4 carbine, a weapon capable of firing in multi-bullet bursts. ?

The Tsarnaev brothers also threw or dropped explosive devices, apparently loaded from their Cambridge, Mass., apartment into a hijacked car, Commissioner Davis said. The devices caused "one extremely loud explosion? and several others, he said.

Some news reports have also said the suspects made pipe bombs, although those were not mentioned in the criminal complaint against the surviving brother, filed Monday by FBI Special Agent Daniel Genck in US District Court in Massachusetts.

The substantial arsenal doesn?t answer the question of whether the perpetrators acted alone or had aid or instruction from others. Terrorism experts have expressed mixed views on that question.

Some have criticized Boston Mayor Thomas Menino for publicizing the idea that the brothers probably acted alone, while others have embraced that same idea ? saying the deeds could be done on their own even if there was one or more additional individual who influenced the ?radicalization? of thought that led to the attacks.

Special Agent Genck described the marathon-day devices as ?low-grade? explosives housed in pressure cookers. He says a device deployed at the scene of a shootout with the Tsarnaevs later last week in the Boston suburb of Watertown used the same brand of pressure cooker and the same kind of green hobby fuse.

Some terrorism experts say the know-how to make such explosive devices is obtainable on the Internet, while others say it's likely that some training was behind the building of these improvised explosive devices (IEDs). Investigators have recovered at least two unexploded devices from the shootout scene, as well as pieces of exploded devices, to analyze.

Davis of the Boston Police said the federal officials are now trying to trace where the firearms used in the gun battle came from.

The shootout has brought out familiar views on gun control. Gun-rights proponents argue that criminals will always circumvent restrictions. But proponents say a tighter system of oversight on gun purchases would make these weapons harder to acquire and impose greater accountability on those who sell guns.

Ant family tree constructed: Confirms date of evolutionary origin, underscores importance of Neotropics

Apr. 22, 2013 ? Anyone who has spent time in the tropics knows that the diversity of species found there is astounding and the abundance and diversity of ants, in particular, is unparalleled. Scientists have grappled for centuries to understand why the tropics are home to more species of all kinds than the cooler temperate latitudes on both sides of the equator. Several hypotheses have been proposed to explain the higher species numbers in the tropics, but these hypotheses have never been tested for the ants, which are one of the most ecologically and numerically dominant groups of animals on the planet.

New research by evolutionary biologists Dr. Corrie Moreau of Chicago's Field Museum and Dr. Charles Bell of the University of New Orleans is helping answer these questions. Their findings are presented this week in the journal Evolution.

The scientists used DNA sequence data to build the largest ant tree-of-life to date. This tree-of-life, or family tree of ants, not only allowed them to better understand which ant species are related, but also made it possible to infer the age for modern ants because information from the fossil record in the form of geologic time was included in the research.

This ant tree-of-life confirmed an earlier surprising finding that two groups of pale, eyeless, subterranean ants, which are unlike most typical ants, are the earliest living ancestors of the modern ants. The time calibrated ant tree-of-life showed that the ants found on the planet today can trace their evolutionary origins back to between 139 and158 million years ago -- during the time the dinosaurs walked the Earth (a finding in line with previous studies).

But why are there more species of ants in the tropics? To explain this pattern of higher species diversity for many tropical organisms, biologists have used the analogies of the tropics acting as a "museum" or "cradle" for speciation. In the case of the museum analogy, the tropical climates have more species because this is where the oldest groups persist throughout evolutionary time. The converse of this explanation is that the tropics are a cradle where new species are more likely to be generated.

To better understand where on the planet the ants arose and if any single geographic area was more important for their evolutionary origins, Moreau and Bell reconstructed the biogeographic history of the ants. These analyses found that the Neotropics of South America were vital to the deep and continued evolutionary origin of the ants. This finding suggests that for the ants the rainforests of the Neotropics are both a museum, protecting many of the oldest ant groups, and also a cradle that continues to generate new species.

As ants are one of the most ecologically important groups of terrestrial organisms, these findings suggest that protecting the rainforests of the Neotropics are vital to the health and success of both the ants that live in them and all the other animals, plants, fungi, and microbes worldwide that rely on ants to survive.

Congress pushes for ?Internet Freedom? as U.N. showdown looms

The House is pushing forward in an effort to block a United Nations-related group from potentially allowing countries to censor the Internet, before an international showdown this fall.

Internet_Archive_mirror_serversThe House Energy and Commerce Committee approved a draft bill, with little fanfare last week, that repeated a claim that ?it is the policy of the United States to preserve and advance the successful multi-stakeholder model that governs the Internet.?

Congress had passed a resolution to that effect last year, but now it?s seeking to get an official law on the books before a big international conference in October in South Korea.

Some contentious language was struck from the bill that might have affected the current policy of net neutrality, which allows the federal government to make sure Internet providers provide equal access to companies that want to stream video and other content.

But the basic gist of the bill was to make sure a message was sent to U.N.-sponsored International Telecommunications Union (ITU).

Last December, the United States and its key allies didn?t sign a draft ITU treaty in Dubai that proposed that individual nations had the power to potentially censor the Internet.

The last-second addition of wording about the rights of all nations to have a role in controlling the Internet sparked outrage from Western nations.

This February, departing Federal Communications Commissioner Robert McDowell warned the House committee that the ITU had plans that weren?t in the best interest of the United States.

?Last year?s bipartisan and unanimous congressional resolutions clearly opposing expansions of international powers over the Internet reverberated throughout the world and had a positive and constructive effect,? he said.

?The dramatic encroachments on Internet freedom secured in Dubai will serve as a stepping stone to more international regulation of the Internet in the very near future. The result will be devastating even if the United States does not ratify these toxic new treaties,? he added.

McDowell said the meeting this fall in South Korea will be ?literally a constitutional convention? to ?define the ITU?s mission for years to come. Its constitution will be rewritten and a new Secretary General will be elected. This scenario poses both a threat and an opportunity for Internet freedom. The outcome of this massive treaty negotiation is uncertain, but the momentum favors those pushing for more Internet regulation.?

The ITU is seeking to update a 1988 document called the International Telecommunication Regulations Treaty. It is considering controls over the Internet as an expansion of its current mandate over telephones, television, and radio networks.

A late nonbinding provision tacked on to the treaty last year stated: ?The Internet is a central element of the infrastructure of the information economy, and recognizes that all governments should have an equal role and responsibility for international Internet governance, the security and stability of the Internet, and its future development.?

The addendum was sponsored by a bloc of African nations, and Iran led the effort to get it passed by a majority vote.

At the time, former U.S. ambassador Terry Kramer bluntly said his country had no interest in signing the treaty.

?The Internet has given the world unimaginable economic and social benefit during these past 24 years. All without U.N. regulation,? Kramer said.

The event was serious enough that in a highly charged partisan environment of Washington, the Obama administration, top Republicans and Democrats in Congress, and even top tax fighter Grover Norquist all agreed the Internet should be kept free when it comes to access and taxes.

In reality, some countries already block Web access, but an official mandate to let ITU members control how Internet access points are assigned and monitored would make the whole process much easier to manage?and censor.

The Internet Corporation for Assigned Names and Numbers (ICANN) manages domains and controls the Internet?s backbone. ICANN operates as a nonprofit company at the direction of the U.S. Department of Commerce. (Prior to 1998, the U.S. government managed Internet domain names directly.)

Some critics say the real issue is a power grab by the ITU (and the U.N.) to take ICANN away from any swaying influence exerted on it by the U.S. government.

Using black holes to measure the universe's rate of expansion

Apr. 22, 2013 ? Radiation emitted in the vicinity of black holes could be used to measure distances of billions of light years, says TAU researcher

A few years ago, researchers revealed that the universe is expanding at a much faster rate than originally believed -- a discovery that earned a Nobel Prize in 2011. But measuring the rate of this acceleration over large distances is still challenging and problematic, says Prof. Hagai Netzer of Tel Aviv University's School of Physics and Astronomy.

Now, Prof. Netzer, along with Jian-Min Wang, Pu Du and Chen Hu of the Institute of High Energy Physics of the Chinese Academy of Sciences and Dr. David Valls-Gabaud of the Observatoire de Paris, has developed a method with the potential to measure distances of billions of light years with a high degree of accuracy. The method uses certain types of active black holes that lie at the center of many galaxies. The ability to measure very long distances translates into seeing further into the past of the universe -- and being able to estimate its rate of expansion at a very young age.

Published in the journal Physical Review Letters, this system of measurement takes into account the radiation emitted from the material that surrounds black holes before it is absorbed. As material is drawn into a black hole, it heats up and emits a huge amount of radiation, up to a thousand times the energy produced by a large galaxy containing 100 billion stars. For this reason, it can be seen from very far distances, explains Prof. Netzer.

Solving for unknown distances

Using radiation to measure distances is a general method in astronomy, but until now black holes have never been used to help measure these distances. By adding together measurements of the amount of energy being emitted from the vicinity of the black hole to the amount of radiation which reaches Earth, it's possible to infer the distance to the black hole itself and the time in the history of the universe when the energy was emitted.

Getting an accurate estimate of the radiation being emitted depends on the properties of the black hole. For the specific type of black holes targeted in this work, the amount of radiation emitted as the object draws matter into itself is actually proportional to its mass, say the researchers. Therefore, long-established methods to measure this mass can be used to estimate the amount of radiation involved.

The viability of this theory was proved by using the known properties of black holes in our own astronomical vicinity, "only" several hundred million light years away. Prof. Netzer believes that his system will add to the astronomer's tool kit for measuring distances much farther away, complimenting the existing method which uses the exploding stars called supernovae.

Illuminating "Dark Energy"

According to Prof. Netzer, the ability to measure far-off distances has the potential to unravel some of the greatest mysteries of the universe, which is approximately 14 billion years old. "When we are looking into a distance of billions of light years, we are looking that far into the past," he explains. "The light that I see today was first produced when the universe was much younger."

One such mystery is the nature of what astronomers call "dark energy," the most significant source of energy in the present day universe. This energy, which is manifested as some kind of "anti-gravity," is believed to contribute towards the accelerated expansion of the universe by pushing outwards. The ultimate goal is to understand dark energy on physical grounds, answering questions such as whether this energy has been consistent throughout time and if it is likely to change in the future.

Boston bombing suspect awake

Dzhokhar Tsarnaev (AP/File)

Boston Marathon bombing suspect Dzhokhar Tsarnaev is awake and "responding sporadically in writing to questions ... about other cell members and other unexploded bombs, " law enforcement sources told ABC News on Sunday evening.

Authorities had been waiting to question the 19-year-old, who is accused of helping to carry out the attack, which killed three people and wounded 180 others, many of them critically, near the finish line of Monday's race.

Earlier Sunday, the FBI said Tsarnaev remains in serious condition at the heavily-guarded Beth Israel Deaconess Medical Center, and a federal official told Yahoo News that Tsarnaev was sedated and unable to speak.

Tsarnaev was brought by ambulance to the facility after he was captured in Watertown, Mass., on Friday, following an intense manhunt that included at least two shootouts with police and ended with the bloodied suspect taken into custody from a tarp-covered boat he had been hiding in. He apparently suffered gunshot wounds to the neck and leg.

Tsarnaev's 26-year-old brother, Tamerlan, the other suspect wanted by the FBI, was killed during a late-night firefight with police in Watertown. Tsarnaev managed to escape on foot, prompting a citywide lockdown as police conducted a house-by-house search for the alleged killer.

[Related: Arrest presents intelligence opportunity]

The Tsarnaev brothers, who were born in the former Russian territory known as Kyrgyzstan and are of Chechen descent, lived in Cambridge, Mass., for several years. Dzhokhar became a naturalized American citizen last year.

Under U.S. law, authorities have 72 hours after Tsarnaev's arrest to file a criminal complaint against him. When they do, Tsarnaev is expected to face terror charges that could bring the death penalty.

"I hope that the U.S. attorney, Carmen Ortiz, takes him on the federal side and throws the book at him," Boston Mayor Thomas Menino said on ABC's "This Week With George Stephanopoulos" on Sunday.

Richard Roper, a former U.S. District Attorney in the Northern District of Texas, told Yahoo News Dzhokhar could be charged in his hospital room.

?Then when he?s better, he can make an appearance in court,? Roper said.

[Slideshow: 'We Got Him': Newspaper covers capture dramatic arrest]

Hours after the FBI made a public plea to help identify the suspects from video and photos at the marathon, the brothers allegedly shot and killed an MIT police officer and wounded a transit cop. Authorities said the pair launched explosives during a dramatic high-speed chase in residential Watertown early Friday.

No motive has been revealed for Monday?s attack.

Immediately after Dzhokhar?s capture, federal prosecutors stirred controversy in legal circles by refusing to grant Dzhokhar his Miranda rights against self-incrimination, citing public safety concerns.

"He is not going to be read the Miranda warnings," ABC News Senior Justice Correspondent Pierre Thomas said Sunday. "They are going to use the Public Safety Exception, and dive in without advising him of his right to remain silent. They are taking this extraordinary step because there could be an imminent threat still out there. ... There's deep, deep concern about the amount of ammunition, guns and working bombs these men had."

Boston Police commissioner Ed Davis told "Fox News Sunday" that the amount of explosives police found suggested that the brothers may have been planning another attack.

"We are hoping, for a host of reasons, that the suspect survives," Massachusetts Gov. Deval Patrick said Saturday. "Because we have a million questions, and those questions need to be answered."

Boston nurses tell of bloody marathon aftermath

(AP) ? The screams and cries of bloody marathon bombing victims still haunt the nurses who treated them one week ago. They did their jobs as they were trained to do, putting their own fears in a box during their 12-hour shifts so they could better comfort their patients.

Only now are these nurses beginning to come to grips with what they endured ? and are still enduring as they continue to care for survivors. They are angry, sad and tired. A few confess they would have trouble caring for the surviving suspect, 19-year-old Dzhokhar Tsarnaev, if he were at their hospital and they were assigned his room.

And they are thankful. They tick off the list of their hospital colleagues for praise: from the security officers who guarded the doors to the ER crews who mopped up trails of blood. The doctors and ? especially ? the other nurses.

Nurses from Massachusetts General Hospital, which treated 22 of the 187 victims the first day, candidly recounted their experiences in interviews with The Associated Press. Here are their memories:

THEY WERE SCREAMING

Megann Prevatt, ER nurse: "These patients were terrified. They were screaming. They were crying ... We had to fight back our own fears, hold their hands as we were wrapping their legs, hold their hands while we were putting IVs in and starting blood on them, just try to reassure them: 'We don't know what happened, but you're here. You're safe with us.' ... I didn't know if there were going to be more bombs exploding. I didn't know how many patients we'd be getting. All these thoughts are racing through your mind."

SHRAPNEL, NAILS

Adam Barrett, ICU nurse, shared the patient bedside with investigators searching for clues that might break the case. "It was kind of hard to hear somebody say, 'Don't wash that wound. You might wash evidence away.'" Barrett cleaned shrapnel and nails from the wounds of some victims, side by side with law enforcement investigators who wanted to examine wounds for blast patterns. The investigator's request took him aback at first. "I wasn't stopping to think, 'What could be in this wound that could give him a lead?'"

THEIR FACES, THEIR SMILES

Jean Acquadra, ICU nurse, keeps herself going by thinking of her patients' progress. "The strength is seeing their faces, their smiles, knowing they're getting better. They may have lost a limb, but they're ready to go on with their lives. They want to live. I don't know how they have the strength, but that's my reward: Knowing they're getting better."

She is angry and doesn't think she could take care of Tsarnaev, who is a patient at another hospital, Beth Israel Deaconess Medical Center: "I don't have any words for him."

THE NEED FOR JUSTICE

Christie Majocha, ICU nurse: "Even going home, I didn't get away from it," Majocha said. She is a resident of Watertown, the community paralyzed Friday by the search for the surviving suspect. She helped save the lives of maimed bombing victims on Monday. By week's end, she saw the terror come to her own neighborhood. The manhunt, she felt, was a search for justice, and was being carried out directly for the good of her patients.

"I knew these faces (of the victims). I knew what their families looked like. I saw their tears," she said. "I know those families who are so desperate to see this end."

On Friday night, she joined the throngs cheering the police officers and FBI agents, celebrating late into the night even though she had to return to the hospital at 7 a.m. the next day.

Paraguayans vote for president; Colorado favored

ASUNCION, Paraguay (AP) ? Paraguayans are voting for president, congress and governors in elections they hope will end the country's isolation from regional groups that challenged last year's impeachment of President Fernando Lugo as a threat to the democracies of neighboring countries.

Most pre-election polls are giving the lead in Sunday's contest to wealthy businessman Horacio Cartes of the Colorado Party. Leading challenger Efrain Alegre of the Radical Liberals says he might not accept the results until votes are certified in May.

The initial count is to be announced Sunday night by Paraguay's Supreme Electoral Court.

Nobel Peace Prize Winner laureate Oscar Arias is leading an observer mission from the Organization of American States. He says he has complete confidence in the results that will be released by the electoral court.

Iraqis vote in first local ballot since U.S. withdrawal

By Patrick Markey

BAGHDAD (Reuters) - A dozen small bombs exploded and mortar rounds landed near polling centers in Iraq on Saturday, wounding at least four people during voting in the country's first provincial elections since the departure of U.S. troops.

Two mortar rounds injured three voters and a policeman at a school used as a voting centre in Latifiya, south of Baghdad, soon after the start of the ballot that will measure parties' political strength before parliamentary elections in 2014.

Attacks have surged since the start of the year with a local al-Qaeda wing and Sunni Islamists stepping up their campaign to undermine the Shi'ite-led government and stoke confrontation among the country's combustible sectarian and ethnic mix.

Small bombs exploded in Tuz Khurmato, Tikrit and Samarra in the north and six more mortar rounds landed in a town near the southern city of Hilla, without causing any injuries, said police.

Iraqi politics is deeply split along sectarian lines with Prime Minister Nuri al-Maliki's government mired in crisis over how to share power between majority Shi'ite Muslims, Sunnis and Kurds who run their own autonomous enclave.

For Maliki, a strong showing by his Shi'ite State of Law alliance may open the way for a shot at a third term in 2014 elections when he has hinted at plans to abandon Iraq's unwieldy power-sharing deal to form a majority government.

Sunni rivals, deeply divided over how to work with his government, and the premier's Shi'ite rivals, anti-U.S. cleric Moqtada al-Sadr and the ISCI movement, will look to chip away at Maliki's sway over provincial councils.

Security was tight across Iraq with more than 8,000 hopefuls running for nearly 450 seats on provincial councils which select local governors. More than a dozen candidates, mostly Sunnis, were killed during campaigning.

Early turnout at polling stations in Baghdad, and cities like Basra, Tikrit and Baquba appeared light, according to Reuters reporters.

Many Iraqis are frustrated with insecurity, unemployment, rife corruption and the lack of basic services a decade after the invasion that ousted Saddam Hussein and helped trigger sectarian bloodshed that killed tens of thousands in 2006-2007.

Attacks on a Sunni and a Shi'ite mosque on Friday killed at least eight. A suicide bomber killed 32 people in a blast at a popular cafe in a mostly Sunni neighborhood in Baghdad a day before.

Since American troops left in December 2011, Iraqi politics has been paralyzed by infighting over power-sharing agreements with Maliki's rivals accusing the Shi'ite premier of consolidating power at the expense of Sunni and Kurdish partners.

"I took part in past elections, but all those we elected did nothing for the people," said Ali Hussein Sharqi, voting in the southern oil hub of Basra. "We want people who will offer jobs to the jobless."

SUNNI DISCONTENT

Three provinces in Iraq's autonomous Kurdistan region, run by ethnic Kurds since 1991, and the ethnically mixed, disputed city of Kirkuk, will not be voting on Saturday.

Washington weighed into the election process, asking the government not to alienate Sunni voters after the Cabinet postponed voting in two mostly Sunni provinces because local officials warned they could not provide security there.

Since December, tens of thousands of Sunni Muslim protesters have taken to the streets each week to demonstrate against what they say is the marginalization of their minority sect.

Election authorities say suspended voting in Anbar and Nineweh provinces may go ahead in a month.

But ten years after the invasion, many Iraqi Sunnis feel they have been sidelined by the country's majority Shi'ite leadership and discriminated against by Iraqi security forces and tough anti-terrorism laws.

"Suspending elections was the coup de grace for the demonstrations. We've as lost everything," said Maitham Jalal, a college student in Anbar province. "Elections are a legitimate right which was taken away by the government without any fear."

Sunni-backed Iraqiya block has struggled to stay united with its leadership split over how to manage relations with Maliki. Those divisions are likely to play out in the provincial election results.

"Overall the elections are likely to see Iraq stumble further along the trajectory on which is has already been headed for some time: to stratified, sectarian politics," Eurasia Group analyst Crispin Hawes wrote in a report.

Extra security in place as London Marathon begins

(AP) ? The London Marathon started as planned on a glorious sunny morning Sunday despite concerns raised by the bomb attacks on the Boston Marathon six days ago.

Some 36,000 runners are expected to take part, with extra layers of security added by police and race organizers as a precautionary measure.

Police said they planned to add 40 percent more officers and extra surveillance, and police helicopters were in the air as the race got under way.

London's is the first major international marathon since the double bomb attack near the finish line in Boston. One suspect was killed during police attempts to capture him, while a second was later arrested.

London police and organizers said the extra measures would assure safety at the starting and finishing points of the popular event, which usually draws tens of thousands of fans to the city streets.

A 30-second moment of silence was held before the start of the event to honor those injured in the Boston Marathon. In addition, the marathon organizers plan to donate money to a Boston fund set up to help victims there.

The Monday bombing there left three people dead and more than 170 injured, including many who are still hospitalized. In addition, a policeman was killed during the search for the two suspected bombers.

Runner Martin Connell, 42, wore a picture of 8-year-old Boston bombing victim Martin Richard on his jersey in tribute to his young namesake.

"It's a sign of peace and goodwill," said the runner, an IT worker from near Liverpool.

The organizers of the London Marathon said they did not consider canceling the event, which is a highlight of the sporting calendar.

'Real Housewives of New Jersey' Season 5 promo: The family tree is ...


Season 5 of "The Real Housewives of New Jersey" is only a few months away (premiering June 2 at 8 p.m. ET) and, if this first promo is any indication, the family drama is only growing.

The trailer, released on Friday (April 19) by Bravo, finds Garden State beauties Melissa Gorga, Jacqueline Laurita and Kathy Wakile pretending to plant a tree and watch it grow, before Teresa Giudice can carve her and husband Joe's initials into the full-grown plant while no-nonsense Caroline Manzo looks on disapprovingly.

"Family is a force of nature," the tagline reads, while a bolt of lightning strikes the tree, spitting it in half.

The trailer marks the second series in the franchise to receive a big-budget trailer for a new season, something the network began with Season 3 of "Real Housewives of Beverly Hills" last fall.

Be sure to watch the full trailer above. Is it June yet?

Study finds scientific basis for 'chemo brain' in breast cancer patients

Study Finds Scientific Basis for ?Chemo Brain? in Breast Cancer Patients




By Janice Wood Associate News Editor

chemo brainWhile breast cancer patients often report difficulties with memory, concentration and other cognitive functions following treatment, there?s been a debate in the medical community as to whether this mental fogginess is psychosomatic or a symptom of changes in brain function.

Now, a new study has shown a correlation between poorer performance on neuropsychological tests and memory complaints in post-treatment, early-stage breast cancer patients, particularly those who have undergone chemotherapy and radiation.

?The study is one of the first to show that such patient-reported cognitive difficulties ? often referred to as ?chemo brain? in those who have had chemotherapy ? can be associated with neuropsychological test performance,? said Dr. Patricia Ganz, director of cancer prevention and control research at the University of California-Los Angeles?s Jonsson Comprehensive Cancer Center.

Ganz and her colleagues looked at 189 breast cancer patients who enrolled in the study about a month after completing their initial breast cancer treatments and before beginning endocrine hormone-replacement therapy. Two-thirds had breast-conserving surgery, more than half had received chemotherapy, and three-quarters had undergone radiation therapy. Average age of the women was 52.

Because cognitive complaints following cancer treatment have often been associated with anxiety and depressive symptoms, the researchers excluded women with serious depressive symptoms. They also took into account the cancer treatments used and whether menopause and hormonal changes could be influencing the cognitive complaints. A group of healthy women of about the same age was used as a control group.

The researchers gave a self-reporting questionnaire to the women and found that those with breast cancer reported more severe complaints than normal ? 23.3 percent had higher complaints about their memory, and 19 percent reported higher complaints about higher-level cognition, such as problem-solving and reasoning.

The researchers noted that the breast cancer patients who reported more severe memory and higher-level cognition problems were more likely to have undergone both chemotherapy and radiation.

The UCLA researchers found that even when patients reported subtle changes in their memory and thinking, neuropsychological testing showed detectable differences.

For instance, they discovered that poorer performance on the neuropsychological test was associated with higher levels of cognitive complaints and with combined radiation and chemotherapy treatment, as well as with symptoms related to depression.

?In the past, many researchers said that we can?t rely on patients? self-reported complaints or that they are just depressed, because previous studies could not find this association between neuropsychological testing and cognitive complaints,? Ganz said. ?In this study, we were able to look at specific components of the cognitive complaints and found they were associated with relevant neuropsychological function test abnormalities.?

The findings are part of an ongoing study that seeks to examine the extent to which hormone therapy contributes to memory and thinking problems in breast cancer survivors, she said. This latest study provided a pre-hormone therapy assessment, which was able to separate the effects of initial treatments on these cognitive problems, she said. Earlier post-treatment studies of breast cancer patients were difficult to interpret, as they included women already taking hormone therapy, she noted.

?As we provide additional reports on the follow-up testing in these women, we will track their recovery from treatment, as well as determine whether hormone therapy contributes to worsening complaints over time,? Ganz said.

The study was published in the Journal of the National Cancer Institute.

The Trouble With Turning a Camera on Washington

Toward the end of Wednesday night?s ?Sidecar Conversation Series? on the love/hate relationship between Hollywood and D.C. ? a discussion which was, at turns, self-congratulatory and hyper critical ? moderator Ron Brownstein asked the entertainment-savvy panelists to name the defining political flick.

Our own Neda Semnani originally blurted out ?The Candidate,? but then amended her choice to tout ?Inherit the Wind?:

?Chasing the Hill? creator and NBC alumnus Brent Roske kept it in the family, tossing his support behind ?The West Wing?:

Bono proxy Michael Elliott made a case for Robert Altman?s hippie, trippy ?Nashville?:

?House of Cards? Executive Producer Beau Willimon went big, giving Orson Welles mad props for ?Citizen Kane?:

Brownstein, meanwhile, sang the praises of ?The Man Who Shot Liberty Valance?:

While many of the aforementioned efforts attempt to expose the underbelly of politics via one trope or another, we would argue that the seminal Tinsel Town-Washington tryst never sizzled across the silver screen. No, the most honest moment between our seedy universes played out, as is so often the case on Capitol Hill, right under everyone?s noses:

As for the heated debate about the entertainment industry?s continuously dismissive treatment of female reporters, we?ll let ?Saturday Night Live? have the last word on that:

Laser optics plus ultrasound imaging holds promise as a noninvasive test for prostate cancer

Multispectral photoacoustic imaging, which combines laser optics and ultrasound imaging technologies, can reliably distinguish between benign and malignant prostate tissue, a new study indicates.

Researchers at the University of Rochester looked at 42 prostatectomy specimens using the new imaging technique. Multispectral photoacoustic imaging, still in its infancy, predicted 25 out of 26 benign tissues correctly and 13 out of 16 malignant tissues correctly, said Dr. Vikram Dogra, lead author of the study.

Lipids, water, oxyhemoglobin and deoxyhemoglobin in the blood all respond to laser light, said Dr. Dogra. "By observing increases and decreases in these four things, we can tell if the tissue is malignant or benign, he said. "Deoxyhemoglobin is the biggest distinguisher between malignant and benign. If deoxyhemoglobin increases even slightly in intensity, the odds that the tissue is malignant increases dramatically," he said.

Prostate cancer is the second leading cause of cancer death in American men. Transrectal ultrasound, the current gold standard to diagnose prostate cancer, has an overall success rate of about 70%, said Dr. Dogra. "Transrectal ultrasound is an invasive procedure and most men do not like it. There is a need for a new imaging technique," Dr. Dogra said. "We expect this technique to be clinically available in about five years," he added.

Dr. Dogra will present his study at the ARRS annual meeting on April 18 in Washington, DC.
