Obama Hosts Kennedy Center Honorees

WASHINGTON, D.C. - Seven entertainment icons were hosted at the White House today for their contributions to the performing arts.

Actor Dustin Hoffman, blues guitarist Buddy Guy, ballerina Natalia Makarova, and comedian David Letterman were given a reception with the three surviving members of Led Zeppelin before the annual Kennedy Center Honors gala this evening. President Obama welcomed the performers before they were presented their awards at the event later inthe evening.

The president joked that the motley crew's presence continued "a tradition at the White house by honoring some extraordinary people with no business being on the same stage together."

"Here in America, more than any other place on Earth we are free to follow our own passions, explore our own gifts, wherever they may lead us," he said. "And people from all around the world come here to make sure that they too can provide us the incredible gifts that they have."

The individuals had one thing in common: all came from what the president called "humble beginnings."

"Growing up as the son of a share cropper in Louisiana, Buddy Guy made his first guitar out of wires from a window screen," he said, later adding the artist is now one of the "last guardians of the great American blues."

Makarova, on the other hand, defected from the Soviet Union in 1970 only to find her name excised from the record in her homeland.

"But no one can erase what takes hold in the heart," he continued. "In 1989 when the iron curtain opened, the Russian people welcomed her back with open arms. Over 2,000 people packed in the Kirov Theater where she had trained when she was younger. Another 20 people crammed in the orchestra."

While Dustin Hoffman and David Letterman started as a struggling young actor and weatherman respectively, Obama credited the surviving members of Led Zeppelin - Robert Plant, Jimmy Page and John Paul Jones - with redefining the rock genre and its lifestyle. The president said it was "fitting" the room had three-inch thick windows, given the band's history of trashing hotels.

Together, the talent assembled reminded the country of the "unique power that makes the arts so important," he concluded.

"Each of us can remember a moment when the people on this stage touched our lives," he said. "Maybe they didn't lead us to become performers ourselves. But maybe they inspired us to see things in a new way, to hear things differently, to discover something within us or to appreciate how much beauty there is in the world. It's that unique power that makes the arts so important."

Home of the National Symphony Orchestra, the John F. Kennedy Center for the Performing Arts is one of Washington's most recognizable institutions for the field. Their annual awards ceremony is a star-studded affair, bringing the elite of the music, dance, film, theater and TV worlds together with Washington high society.

The Kennedy Center Honors has no categories or competition, selecting recipients solely for lifetime contributions to entertainment culture. It is probably one of the few occasions where one would see awards given to both a Russian ballerina and a man known for airing "stupid pet tricks."

Obama and the first lady were also in attendance at the main event at the performing arts center.

Police: Hero instructor fought son in arrow attack

CASPER, Wyo. (AP) ? Gravely wounded by an arrow fired into his head, a Wyoming college instructor still managed to wrestle with his 25-year-old son who carried out the attack and give his students time to flee the classroom, say police who hailed the actions as heroic.

More grisly details of the horrific murder-suicide in Wyoming came to light Saturday, a day after the younger man killed his father's live-in girlfriend and then barged into his father's computer science class and shot him in the head with a high-powered bow and arrow.

As James Krumm, 56, then fought with son Christopher Krumm of Vernon, Conn., during Friday's attack, the handful of students in the Casper College classroom escaped.

Christopher Krumm had just stabbed to death 42-year-old Heidi Arnold at the home she shared with James Krumm two miles away.

When police arrived at the classroom, they found Christopher Krumm bleeding from self-inflicted knife wounds and taking his last breaths.

James Krumm was dead, Casper Police Chief Chris Walsh said.

"I can tell you the courage that was demonstrated by Mr. Krumm was absolutely without equal," he said, adding that the instructor's actions could offer some measure of comfort to those affected by the killings.

Authorities believe "around six" students were in the classroom when Christopher Krumm entered, Casper police spokesman Justin Smith said. No students were hurt.

Walsh said police still were trying to figure out what motivated Christopher Krumm to attack his father and Arnold, a math instructor at the college. Arnold died of multiple stab wounds.

After shooting his father with the arrow, Christopher Krumm stabbed himself, then fatally stabbed his father in the chest in a struggle in the classroom, Walsh said.

Police began getting reports about the attack on Arnold soon after they responded by the dozen to the campus attack. Authorities locked down the campus for two hours while they scoured the grounds for any other attackers. They were reassured that Christopher Krumm acted alone.

He had smuggled the compound bow ? a type much more powerful and effective for hunting than a simple, wooden bow ? onto campus beneath a blanket, Walsh said.

He said Christopher Krumm also had two knives with him, and the knife used was "very large."

Arnold's body was found in the gutter of her street, and evidence suggested much of the attack occurred outside the home, Walsh said.

Neighbor Heather Meier said she came home from work Friday afternoon after picking up her 7-year-old daughter from school, and the two saw Arnold's body still lying in the street.

"As soon as we got home, we just shut the curtains," she said Saturday. "You know, tried to just watch some TV, have some snacks, mind our own business."

Across the street from her home, crime tape cordoned off Krumm and Arnold's faded blue and yellow house and part of the street. Meier, who has lived in the neighborhood for two years, said she met Arnold and James Krumm only once a few months ago and described them as quiet and very private.

Casper College instructor Kevin McDermott said Arnold and James Krumm were well-liked on campus.

"I knew these people pretty well, so it's hurting me. ... It's breaking my heart," said McDermott, who teachers algebra and computer networking at the school. "They were really good, kind-hearted people. People like Jim and Heidi are what make Casper College such a great college."

McDermott described James Krumm as a "real kind and gentle-mannered guy" who was well-respected by his students.

"Computer science majors took most of their classes from Jim. He was their adviser, and he had a big impact on them," he said.

McDermott added Arnold was a great teacher who "taught the tough stuff" and maintained a sunny disposition ? "a person who always had a smile on her face."

Chris Unruh, a student in one of Arnold's pre-calculus classes this fall, said she was a kind instructor who was excited about recently getting two dogs.

"She cared about her students," said Unruh, 18. "She wanted all of them to succeed."

Investigators said Christopher Krumm had recently driven to Casper from Connecticut and had been staying at a local hotel. He had no significant history of encounters with police.

Authorities were uncertain what went awry in his relationship with his father.

"It's difficult to say. I don't think it was very close," Walsh said.

In Vernon, Conn., police Sgt. Timothy O'Connor said officers executed a search warrant at Christopher Krumm's last known address Friday to help authorities in Casper. He didn't know what investigators were looking for or may have found at the home.

"Whatever was recovered will be turned over to Wyoming because it is an active investigation," O'Connor said.

Christopher Krumm's previous addresses include one in the western Massachusetts city of Springfield and others in the Colorado cities of Golden, Fort Collins and Lakewood.

Casper, population 56,000, is about 250 miles northwest of Denver and Wyoming's second-largest city after the state capital, Cheyenne. Wyomingites refer to Casper as the "Oil City" because it is a hub of the state's oil industry.

Casper College is one of seven colleges in Wyoming's community college system. The campus was mostly quiet Saturday morning. Fathers and sons shot hoops in the school gym. A small group of drama students rehearsed a play in the school theater just across the street from the attack.

The building where the attack happened remained cordoned off by police tape that whipped in a brisk wind. A security guard let students back in, one at a time, to retrieve belongings they'd left behind.

Andra Charter, a 20-year-old sophomore, emerged with a coffee mug. She recalled hearing screams outside her biology class before getting word about what had happened.

"As we were walking out, there was a girl screaming, 'There's somebody stabbing Mr. Krumm!'" Charter said.

James Krumm was head of the college's computer science department. He was born north of London and also spent part of his childhood in Germany, according to the college website.

He held degrees from Casper College, a bachelor's degree and MBA from the University of Wyoming and a master's in computer science from Colorado State University.

Arnold held a master's degree in mathematics from the University of Oregon and a bachelor's degree in math from University of California Davis.

The college planned a candlelight vigil and memorial service Tuesday.

New Jersey bridge collapse derails freight train; chemical leaks

PAULSBORO, New Jersey (Reuters) - A rail bridge collapsed on Friday over a creek in southern New Jersey, causing a Conrail freight train to derail and spill hazardous chemicals into the air and water, authorities said.

One of four tanks of the freight train carrying vinyl chloride fell into Mantua Creek, and its contents leaked into the waterway, which feeds into the Delaware River near Philadelphia, according to the New Jersey Department of Environmental Protection.

Some 22 people were taken to a nearby hospital for precautionary examinations and were doing fine, said Larry Ragonese, a DEP spokesman who said the health danger and environmental impact was minimal.

"Initially there was a release of gas into the air that affected some nearby residents and people working right in that area," he said.

Exposure to vinyl chloride, a highly toxic and flammable industrial chemical, can cause burning eyes or respiratory discomfort, he said.

Authorities evacuated a half-mile (805-metre) area around the spill, which took place at about 7 a.m. EST (1200 GMT) in Paulsboro, New Jersey, just across the Delaware River from Philadelphia, the U.S. Coast Guard said.

Local schools were closed and students were sent home, authorities said.

The leak was contained and no longer posed a threat, and authorities were using booms to trap the chemical in the water, Ragonese said.

At the scene, one of the freight cars was nearly vertical, nose-down and partly submerged in the creek. Other cars lay jumbled on the embankment.

"It's part of living in Paulsboro, with refineries and trains. We accept it," said resident John Diamond, 53, who was taking photographs at the scene.

The area is thick with chemical plants, and two refineries, PBF Energy's Paulsboro and Nustar's Asphault, are nearby.

Locals fish and go crabbing and jet-ski in the creek in the warm months, Diamond said.

Air quality monitors in the area did not register any problem, said Lawrence Hajna, also with the state DEP.

"All the levels are coming in within our safety range," he said.

The swing bridge that collapsed underwent extensive repairs after getting damaged in a 2009 derailment of a coal freight train, said John Burzichelli, a state assemblyman and former mayor of Paulsboro.

New Jersey State Senate President Steve Sweeney, also on the scene, said a nearby homeowner reported hearing a "loud bang" from the bridge about two days ago, and Burzichelli said Conrail had come out to examine it in response.

"That bridge is very old. It's not a good day for Conrail," Burzichelli said.

Conrail officials could not be immediately reached for comment. Sweeney said he too was having trouble getting in contact with Conrail.

Conrail is jointly owned by rail operators CSX Corp and Norfolk Southern Corp.

The U.S. Coast Guard was responding to the accident along with the DEP.

NEW YORK (AP) ? Before purchasing a shirt, shoppers will run their hands over the fabric, look at the price tag and wonder how it will hold up in the washing machine. Some might even ask if it makes them look fat.

The one detail, however, that is rarely considered: What are the conditions like for the workers making the shirt?

A horrific fire that raced through a Bangladesh garment factory Saturday, killing 112 people, has put the spotlight ? at least temporarily ? back on those workers and their sometimes treacherous work environment.

The factory, owned by Tazreen Fashions Ltd., made clothing for several retailers around the globe including Wal-Mart, Sears and The Walt Disney Co. All three companies have distanced themselves from responsibility for the incident, saying they didn't know that their subcontractors were using the factory.

Holiday shoppers have also maintained their distance from the tragedy.

"Truthfully, I hadn't even thought about it," said Megan Miller of Philadelphia as she walked out of the Disney Store in Times Square. "I had Christmas on my mind and getting my kids something from New York."

Shoppers from Cincinnati to Paris to Singapore all said the same thing: They were aware of the fatal factory fire, but they weren't thinking about it while browsing stores in the days since. Brand name, fit and ? above all ? prices were on their minds.

"Either our pockets get lighter or we have to live with more blood on our hands," said Amy Hong, a college student who was at a store in Singapore. "I try not to think about it."

Experts who survey shoppers say the out of sight, out of mind attitude is nothing new.

"When you talk to them about their biggest concerns, where something is made, or the abuses in some country, almost never show up," said C. Britt Beemer, chairman of America's Research Group, which interviews 10,000 to 15,000 consumers a week, mostly on behalf of retailers. "The numbers are so small, I quit asking the question."

Convenience is much more important to shoppers.

Take Tammy Johnson who was at a Walmart in Bloomington, Minn. this week. She lives nearby and appreciates that the store has a large grocery section in addition to clothing and other goods.

"It's easier and it's cheaper," she said of her decision to shop there. "I hate that, but it is true."

Even those who want to make socially responsible purchases a priority have little information available to work with.

There's no widespread system in place to say where all the materials in a shirt come from let alone whether it was made in a sweatshop or not.

A label saying "Made in USA of imported fabrics" doesn't provide as much information to shoppers as they might think. Maybe tailors assembled it under good working conditions, but what about the people who wove the fabrics? Another label saying that a shirt is made from 100 percent organic cotton fails to say anything about the conditions of the factory in which it was made.

"What do they know at the point of sale about where it comes from, other than the tag?" said Paco Underhill, founder of Envirosell, which studies consumer behavior. "Our hearts are generally are in the right places. It's the question of making sure we have the knowledge and pocketbook to follow."

And it's not just clothing. It is hard to tell where televisions or laptop components are made.

Companies selling products say they even struggle to tell. Work is often given to subcontractors who themselves use subcontractors. While many major companies stipulate ethics and standards that their subcontractors must follow, policing them is a costly, time-consuming process that sounds easier than it is.

In the case of the Bangladesh factory, Wal-Mart said it had received a safety audit showing the factory was "high-risk" and had decided months before the blaze to stop doing business with Tazreen. But it said a supplier had continued to use Tazreen without authorization.

In recent years, consumers have become much more aware about the food they eat, and where it comes from.

Supermarkets are full of eggs laid by free-range chickens, organically-grown apples and beef from grass-fed, hormone-free cows. Some upscale restaurants now name the farm that provided them with pork chops. And customers pay a premium for these foods.

The difference: They perceive a direct benefit, since the food is going into their bodies.

Ethical choices when buying clothing ? or the latest version of Apple's iPhone ? are much more blurred.

Jean MacLeod, who was shopping at a Walmart on the south side of Indianapolis, is willing to pay more for goods if they are made in an ethically responsible manner and does it all the time when she buys food.

Walmart wants the best prices for its customers, she said, but the company also has power as a buyer to make sure factories have decent working conditions.

"They should be able to say, 'Look it, we don't want to buy from you unless you do things a little more our way,'" MacLeod said. "If they don't want to buy from them, then that means that factory will go out of business."

Arguments have been made that producing items with cheap labor isn't necessarily a bad thing.

Factories in the Third World can provide jobs with wages well above a region's average. They can help lift families out of severe poverty. The catch is that there are fewer safeguards to protect workers from being exploited from unscrupulous employers.

At the Bangladesh factory, locked exits prevented many workers from escaping after fire broke out.

It draws eerie parallels to New York's Triangle Shirtwaist Fire of 1911, where 146 people died within 18 minutes of a fire starting in a factory with locked exits.

That fire was the catalyst for widespread changes in labor laws in U.S. But in the 100 years since, the desire for cheap clothing hasn't abated and costly labor has just shifted to factories overseas.

"To put it maybe too frankly, profit and efficiency and competition always trump safety and health," said James A. Gross, a labor relations professor at Cornell University.

Not every company sees things that way.

Los Angeles-based American Apparel promotes itself as a line of "sweatshop free" clothing. Its founder and CEO, Dov Charney, said that companies can control working conditions ? they just need to bring production closer to home. American Apparel knits, dyes, cuts and sews all of its products in-house.

"When the company knows the face of its worker, that's important," Charney said. "You can control working conditions and quality."

Yes, American Apparel spends more on labor, but it isn't as much as you would expect. Charney estimates that an imported T-shirt selling for $6 at Walmart would cost about $6.30 if produced domestically thanks to the company's massive scale.

"The consumer can care. They can buy from companies that are committed to fair trade and try to seek out those companies," he said.

Take Nike.

In the mid-1990s, the sneaker giant came under pressure to change its ways after numerous reports of child labor, low wages and poor working conditions. Eventually wages climbed, minimum age requirements were put in place and Nike increased monitoring at its factories.

But such change only comes after persistent public pressure.

"Clothes makers will always do what they want, but the buyer should educate himself," said Paris shopper Pierre Lefebvre.

Not all buyers have that luxury. Family budgets are tight.

"Especially with this economy, we like our money to go as far as it can," said Lesley Schuldt, who left a Cincinnati Macy's this week with five shopping bags worth of jewelry, cookware and gifts. "I have no idea where half the stuff I bought was made, but I imagine it was not in the U.S."

Even brown dwarfs may grow rocky planets: Sizing up grains of cosmic dust around failed star

ScienceDaily (Nov. 30, 2012) ? Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time found that the outer region of a dusty disc encircling a brown dwarf contains millimetre-sized solid grains like those found in denser discs around newborn stars. The surprising finding challenges theories of how rocky, Earth-scale planets form, and suggests that rocky planets may be even more common in the Universe than expected.

Rocky planets are thought to form through the random collision and sticking together of what are initially microscopic particles in the disc of material around a star. These tiny grains, known as cosmic dust, are similar to very fine soot or sand. However, in the outer regions around a brown dwarf -- a star-like object, but one too small to shine brightly like a star -- astronomers expected that grains could not grow because the discs were too sparse, and particles would be moving too fast to stick together after colliding. Also, prevailing theories say that any grains that manage to form should move quickly towards the central brown dwarf, disappearing from the outer parts of the disc where they could be detected.

"We were completely surprised to find millimetre-sized grains in this thin little disc," said Luca Ricci of the California Institute of Technology, USA, who led a team of astronomers based in the United States, Europe and Chile. "Solid grains of that size shouldn't be able to form in the cold outer regions of a disc around a brown dwarf, but it appears that they do. We can't be sure if a whole rocky planet could develop there, or already has, but we're seeing the first steps, so we're going to have to change our assumptions about conditions required for solids to grow," he said.

ALMA's increased resolution compared to previous telescopes also allowed the team to pinpoint carbon monoxide gas around the brown dwarf -- the first time that cold molecular gas has been detected in such a disc. This discovery, and that of the millimetre-size grains, suggest that the disc is much more similar to the ones around young stars than previously expected.

Ricci and his colleagues made their finding using the partially completed ALMA telescope in the high-altitude Chilean desert. ALMA is a growing collection of high precision, dish-shaped antennas that work together as one large telescope to observe the Universe with groundbreaking detail and sensitivity. ALMA "sees" the Universe in millimetre-wavelength light, which is invisible to human eyes. Construction of ALMA is scheduled to finish in 2013, but astronomers began observing with a partial array of ALMA dishes in 2011.

The astronomers pointed ALMA at the young brown dwarf ISO-Oph 102, also known as Rho-Oph 102, in the Rho Ophiuchi star-forming region in the constellation of Ophiuchus (The Serpent Bearer). With about 60 times the mass of Jupiter but only 0.06 times that of the Sun, the brown dwarf has too little mass to ignite the thermonuclear reactions by which ordinary stars shine. However, it emits heat released by its slow gravitational contraction and shines with a reddish colour, albeit much less brightly than a star.

ALMA collected light with wavelengths around a millimetre, emitted by disc material warmed by the brown dwarf. The grains in the disc do not emit much radiation at wavelengths longer than their own size, so a characteristic drop-off in the brightness can be measured at longer wavelengths. ALMA is an ideal instrument for measuring this drop-off and thus for sizing up the grains. The astronomers compared the brightness of the disc at wavelengths of 0.89 mm and 3.2 mm. The drop-off in brightness from 0.89 mm to 3.2 mm was not as steep as expected, showing that at least some of the grains are a millimetre or more in size.

"ALMA is a powerful new tool for solving mysteries of planetary system formation," commented Leonardo Testi from ESO, a member of the research team. "Trying this with previous generation telescopes would have needed almost a month of observing -- impossibly long in practice. But, using just a quarter of ALMA's final complement of antennas, we were able to do it in less than one hour!" he said.

In the near future, the completed ALMA telescope will be powerful enough to make detailed images of the discs around Rho-Oph 102 and other objects. Ricci explained, "We will soon be able to not only detect the presence of small particles in discs, but to map how they are spread across the circumstellar disc and how they interact with the gas that we've also detected in the disc. This will help us better understand how planets come to be."
