End of the line for Roadrunner supercomputer

It's the end of the line for Roadrunner, a first-of-its-kind collection of processors that once reigned as the world's fastest supercomputer.

The $121 million supercomputer, housed at one of the nation's premiere nuclear weapons research laboratories in northern New Mexico, will be decommissioned Sunday.

The reason? The world of supercomputing is evolving and Roadrunner has been replaced with something smaller, faster, more energy efficient and cheaper. Still, officials at Los Alamos National Laboratory say it's among the 25 fastest supercomputers in the world.

"Roadrunner got everyone thinking in new ways about how to build and use a supercomputer," said Gary Grider, who works in the lab's high performance computing division. "Specialized processors are being included in new ways on new systems and being used in novel ways. Our demonstration with Roadrunner caused everyone to pay attention."

In 2008, Roadrunner was first to break the elusive petaflop barrier by processing just over a quadrillion mathematical calculations per second.

Los Alamos teamed up with IBM to build Roadrunner from commercially available parts. They ended up with 278 refrigerator-size racks filled with two different types of processors, all linked together by 55 miles of fiber optic cable. It took nearly two dozen tractor trailer trucks to deliver the supercomputer from New York to northern New Mexico.

The supercomputer has been used over the last five years to model viruses and unseen parts of the universe, to better understand lasers and for nuclear weapons work. That includes simulations aimed at ensuring the safety and reliability of the nation's aging arsenal.

As part of the U.S. nuclear stockpile stewardship program, researchers used Roadrunner's high-speed calculation capabilities to unravel some of the mysteries of energy flow in weapons.

Los Alamos has been helping pioneer novel computer systems for decades. In 1976, the lab helped with the development of the Cray-1. In 1993, the lab held the fastest supercomputer title with the Thinking Machine CM-5.

"And to think of where we're going to be in the next 10 to 15 years, it's just mindboggling," said lab spokesman Kevin Roark.

Right now, Los Alamos ? along with scientists at Sandia National Laboratories in Albuquerque and Lawrence Livermore National Laboratory in California ? is using a supercomputer dubbed Cielo. Installed in 2010, it's slightly faster than Roadrunner, takes up less space and came in at just under $54 million.

Roark said in the next 10 to 20 years, it's expected that the world's supercomputers will be capable of breaking the exascale barrier, or one quintillion calculations per second.

There will be no ceremony when Roadrunner is switched off Sunday, but lab officials said researchers will spend the next month experimenting with its operating system and techniques for compressing memory before dismantling begins. They say the work could help guide the design of future supercomputers.

Huntington Ingalls gets $2.6B Navy ship contract

NEWPORT NEWS, Va. (AP) -- Huntington Ingalls Industries said Friday that it has won a $2.6 billion contract to refuel and overhaul the U.S.S. Abraham Lincoln, a 25-year-old nuclear-powered Naval aircraft carrier.

The company said the ship arrived at its Newport News Shipbuilding division Thursday. Work began immediately and will be complete in November 2016. Huntington Ingalls will refuel the ship's reactors and modernize more than 2,300 compartments, 600 tanks, and hundreds of systems. It also will upgrade the flight deck, catapults, combat systems and the "island," the ship's command center for flight deck operations.

Huntington Ingalls said the price includes costs of the work as well as incentive fees.

The refueling and overhaul was scheduled to start in February, but it was delayed because of concerns about funding and the defense budget. Last week both houses of Congress passed a continuing resolution that will keep the government funded through September 30, the end of its current fiscal year. President Obama signed the stopgap funding measure on Tuesday. Huntington Ingalls said the law allowed the Navy and its shipbuilding division to move ahead with the work.

The Abraham Lincoln was built by Huntington Ingalls' Newport News Shipbuilding unit and launched in February 1988. Huntington Ingalls is the largest military shipbuilder in the U.S., and the company is the biggest industrial employer in Virginia. Newport News Shipbuilding is the nation's only builder of aircraft carriers and one of two submarine builders.

Pope presides over Easter vigil service

By Philip Pullella

VATICAN CITY (Reuters) - Pope Francis, leading the world's 1.2 billion Catholics into Easter for the first time, on Saturday urged those who have strayed from the faith to allow God back into their lives.

Francis, who was elected on March 13, presided at a solemn Easter vigil Mass in St. Peter' Basilica to usher the Catholic Church into the most important day of its liturgical calendar.

The immense basilica, the largest church in Christendom, was in the dark for the start of the service to signify the darkness in Jesus' tomb before what Christians believe was his resurrection from the dead three days after his crucifixion.

Some 10,000 faithful lit candles as Francis, the former Cardinal Jorge Bergoglio of Argentina, walked up the main aisle, and then the basilica's lights were turned on.

The 76-year-old Francis, wearing relatively plain white vestments - as opposed to the more elaborate robes preferred by his predecessor Benedict - delivered a simple homily recounting the Bible story of the women who went to Jesus' tomb but were surprised to find it empty.

He urged his listeners not to be "afraid of God's surprises," never to lose confidence during the trials and tribulations of daily life, and, if they have strayed, to let God back into their lives.

"Let the risen Jesus enter your life, welcome him as a friend, with trust: he is life! If up till now you have kept him at a distance, step forward. He will receive you with open arms," he said, speaking in Italian.

"If you have been indifferent, take a risk: you won't be disappointed. If following him seems difficult, don't be afraid, trust him, be confident that he is close to you, he is with you and he will give you the peace you are looking for and the strength to live as he would have you do," he said.

Another difference between Francis and his predecessor is that Francis reads his homilies standing behind a lectern like an ordinary priest instead of while seated on a throne.

He is still living in the same Vatican guesthouse where he stayed during the conclave that elected him the first non-European pope in 1,300 years instead of moving into the spacious and regal papal apartments in the Vatican's Apostolic Palace.

Francis has also been inviting ordinary people to his morning Mass at the guesthouse, including Vatican street sweepers and gardeners and staff of the guest house.

During Saturday night's service he presided at another Easter vigil tradition by baptizing four new adult members of the Church. They were from Italy, Albania, Russia and the United States.

Holy Saturday was the third of four hectic days leading up to Easter Sunday, the most important day in the Christian liturgical calendar.

On Easter Sunday he will celebrate another Mass and then deliver his first "Urbi et Orbi" (to the city and the world) message from the central balcony of St. Peter's Basilica to tens of thousands of people in the square below.

The balcony is the same spot where he first appeared to the world as pope on the night of March 13 after his election.

Leopards and humans peacefully coexist in India

By Becky Oskin, LiveScience

Leopards and humans peacefully share the same densely populated rural landscape in western India, a new camera trap survey shows.?

The cameras caught leopards and other jungle cats, as well as hyenas and jackals, prowling close to houses through the night in farmland in western Maharashtra, India. The carnivores and people shared the same paths ? so much so that the researchers had to turn off their camera traps during the day because of the human and livestock traffic.?

Yet the leopards went largely undetected by people, according to a statement from the Wildlife Conservation Society (WCS), which helped fund the study.?

"Human attacks by leopards were rare despite a potentially volatile situation considering that the leopard has been involved in serious conflict, including human deaths in adjoining areas," Ullas Karanth of the WCS, a study co-author, said in the statement. "The results of our work push the frontiers of our understanding of the adaptability of both humans and wildlife to each other's presence."?

The findings were published online March 6 in the journal PLOS One.?

The camera traps documented 10 large carnivores per 38 square miles (100 square kilometers) in the densely populated area ? five leopards and five hyenas. The human population density is more than 300 people per 38 square miles.

[ Images: Backyard Leopards Caught on Camera ]?

The discovery of so many large carnivores living in proximity to people highlights the need to focus on conservation outside of protected areas, the researchers said.?

The farming-intensive landscape lacks wilderness and wild herbivores for prey, and the region has only one protected area for wildlife, the Kalsubai Harishchandragarh Wildlife Sanctuary, the researchers said.?

Analysis: NKorea threat may be more bark than bite

SEOUL, South Korea (AP) ? Across North Korea, soldiers are gearing up for battle and shrouding their jeeps and vans with camouflage netting. Newly painted signboards and posters call for "death to the U.S. imperialists" and urge the people to fight with "arms, not words."

But even as North Korean leader Kim Jong Un is issuing midnight battle cries to his generals to ready their rockets, he and his million-man army know full well that a successful missile strike on U.S. targets would be suicide for the outnumbered, out-powered North Korean regime.

Despite the hastening drumbeat of warfare ? seemingly bringing the region to the very brink of conflict with threats and provocations ? Pyongyang aims to force Washington to the negotiating table, pressure the new president in Seoul to change policy on North Korea, and build unity inside the country without triggering a full-blown war.

North Korea wants to draw attention to the tenuousness of the armistice designed to maintain peace on the Korean Peninsula, a truce Pyongyang recently announced it would no longer honor as it warned that war could break out at any time.

In July, it will be 60 years since North Korea and China signed an armistice with the U.S. and the United Nations to bring an end to three years of fighting that cost millions of lives. The designated Demilitarized Zone has evolved into the most heavily guarded border in the world.

It was never intended to be a permanent border. But six decades later, North and South remain divided, with Pyongyang feeling abandoned by the South Koreans in the quest for reunification and threatened by the Americans.

In that time, South Korea has blossomed from a poor, agrarian nation of peasants into the world's 15th largest economy while North Korea is struggling to find a way out of a Cold War chasm that has left it with a per capita income on par with sub-Saharan Africa.

The Chinese troops who fought alongside the North Koreans have long since left. But 28,500 American troops are still stationed in South Korea and 50,000 more are in nearby Japan. For weeks, the U.S. and South Korea have been showing off their military might with a series of joint exercises that Pyongyang sees a rehearsal for invasion.

On Thursday, the U.S. military confirmed that those drills included two nuclear-capable B-2 stealth bombers that can unload the U.S. Air Force's largest conventional bomb ? a 30,000-pound super bunker buster ? powerful enough to destroy North Korea's web of underground military tunnels.

It was a flexing of military muscle by Washington, perhaps aimed not only at Pyongyang but at Beijing as well.

In Pyongyang, Kim Jong Un reacted swiftly, calling an emergency meeting of army generals and ordering them to be prepared to strike if the U.S. actions continue. A photo distributed by North Korea's official Korean Central News Agency showed Kim in a military operations room with maps detailing a "strike plan" behind him in a very public show of supposedly sensitive military strategy.

The head of Germany's foreign intelligence agency, the Federal Intelligence Service, told the Bild am Sonntag newspaper that North Korea's aggressive rhetoric is "not completely new," citing past provocations.

"To sum up: we assume that North Korea does not want a war," Gerhard Schindler was quoted as saying.

North Korea cites the U.S. military threat as a key reason behind its need to build nuclear weapons, and has poured a huge chunk of its small national budget into defense, science and technology. In December, scientists launched a satellite into space on the back of a long-range rocket using technology that could easily be converted for missiles; in February, they tested an underground nuclear device as part of a mission to build a bomb they can load on a missile capable of reaching the U.S.

However, what North Korea really wants is legitimacy in the eyes of the U.S. ? and a peace treaty. Pyongyang wants U.S. troops off Korean soil, and the bombs and rockets are more of an expensive, dangerous safety blanket than real firepower. They are the only real playing card North Korea has left, and the bait they hope will bring the Americans to the negotiating table.

White House spokesman Josh Earnest said North Korea's "bellicose rhetoric" would only deepen its international isolation, and that the U.S. has both the capability and willingness to defend its interests in the region.

Narushige Michishita, director of the Security and International Studies Program at Japan's National Graduate Institute for Policy Studies, isn't convinced North Korea is capable of attacking Guam, Hawaii or the U.S. mainland. He says Pyongyang hasn't successfully tested an intercontinental ballistic missile.

But its medium-range Rodong missiles, with a range of about 800 miles (1,300 kilometers), are "operational and credible" and could reach U.S. bases in Japan, he says.

More likely than such a strike, however, is a smaller-scale incident, perhaps off the Koreas' western coast, that would not provoke the Americans to unleash their considerable firepower. For years, the waters off the west coast have been a battleground for naval skirmishes between the two Koreas because the North has never recognized the maritime border drawn unilaterally by the U.N.

As threatening as Kim's call to arms may sound, its main target audience may be the masses at home in North Korea.

For months, the masterminds of North Korean propaganda have pinpointed this year's milestone Korean War anniversary as a prime time to play up Kim's military credibility as well as to push for a peace treaty. By creating the impression that a U.S. attack is imminent, the regime can foster a sense of national unity and encourage the people to rally around their new leader.

Inside Pyongyang, much of the military rhetoric feels like theatrics. It's not unusual to see people toting rifles in North Korea, where soldiers and checkpoints are a fixture in the heavily militarized society. But more often than not in downtown Pyongyang, the rifle stashed in a rucksack is a prop and the "soldier" is a dancer, one of the many performers rehearsing for a Korean War-themed extravaganza set to debut later this year.

More than 100,000 soldiers, students and ordinary workers were summoned Friday to Kim Il Sung Square in downtown Pyongyang to pump their fists in support of North Korea's commander in chief. But elsewhere, it was business as usual at restaurants and shops, and farms and factories, where the workers have heard it all before.

"Tensions rise almost every year around the time the U.S.-South Korean drills take place, but as soon as those drills end, things go back to normal and people put those tensions behind them quite quickly," said Sung Hyun-sang, the South Korean president of a clothing maker operating in the North Korean border town of Kaesong. "I think and hope that this time won't be different."

And in a telling sign that even the North Koreans don't expect war, the national airline, Air Koryo, is adding flights to its spring lineup and preparing to host the scores of tourists they hope will flock to Pyongyang despite the threats issuing forth from the Supreme Command.

War or no war, it seems Pyongyang remains open for business.

Epsom Salt Benefits Include Softer Skin, Fewer Blackheads And ... A Cleaner House

Epsom salt: Though it includes the name salt and is used in the bath, it's not of the zombie-transforming variety. It's not even salt, actually; it's a mineral comprised of magnesium and sulfate. And while we've long known that it's pretty amazing at easing sore muscles, it does a lot of other things pretty well.

This drugstore staple, which helps eliminate toxins in the body, can effectively multitask as a number of beauty products, as well as household cleaners. Here, five reasons why keeping a big, inexpensive bag around the house is not such a bad idea.

Face scrub: Add a tablespoon amount of epsom salt to your current face wash to create a gentle exfoliator. This recipe also doubles as a body scrub, just mix with olive oil instead for soft, hydrated skin.

Hair clarifier: To remove gunk from products and other hair stylers, mix lemon juice, water and epsom salt to create a pre-shampoo cleanser.

Blackhead fighter: Combine a cup of hot water, epsom salt and a few drops of iodine, then apply the solution to the area. This blend helps loosen dead skin and clears pores.

Splinter remover: According to AARP, epsom salt "increases osmotic pressure on the skin, which draws foreign bodies toward the surface." This works for splinters, as well. Soak the area in a cup of water and epsom salt.

Tile cleaner: Mix epsom salt with liquid dish detergent to create a tile and grout cleaning agent.

Meanwhile, check out eight food items that can double as beauty products:

  • Banana

    These creamy, sweet-smelling fruits make a surprisingly good moisturizing...shave "lotion"? Yes, it's true. Just mash up the banana, adding a little bit of water to achieve a spreadable consistency. Use as you would any other shaving product. The result: Seriously smooth legs. (We definitely recommend using an inexpensive disposable razor, however!) (Getty Photo)

  • Sugar

    Whether white, brown or unrefined, <a href="http://www.stylelist.com/chris-barnes/uses-for-sugar_b_1536525.html?ref=stylelist-home" target="_hplink">sugar makes an excellent exfoliator</a>. We like to mix in about a teaspoon into our usual face wash for a thick scrub. (Getty Photo)

  • Apple Cider Vinegar

    Hair product build-up can leave strands dull and lifeless. But a quick rinse with a 2:1 ratio of apple cider vinegar to water will clarify as well as any commercial product. And no, you won't smell like a salad bar. (Getty Photo)

  • Olive Oil

    Eye make-up removers can get pricey (if you love eyeliner, be prepared to buy a new bottle every 2 weeks), so we were happy to find out that olive oil works just as well. Just dab a little bit on a cotton ball, then wipe away that smoky eye. (Getty Photo)

  • Yogurt

    Spent a little too much time in the sun? Soothe the burn with plain yogurt. A thick mask made using non-flavored yogurt (greek is best) will ease the pain and calm redness. (Getty Photo)

  • Avocado

    It's not just for guacamole. Avocado makes a great hair mask, especially for thick or color-treated hair. Just mash, then work into the ends of hair (we don't recommend getting it on the scalp) and let sit for about 15 minutes. Then, rinse thoroughly. You'll feel the difference almost immediately. (Getty Photo)

  • Coconut Oil

    If you haven't heard the gospel of coconut oil, let us enlighten you now. There's really nothing this health food staple CAN'T do, in terms of beauty. It can bring a non-pore clogging glow to the face, repair split ends and bring parched skin back to life. A miracle, for sure. (Flickr Photo: <a href="http://www.flickr.com/photos/wrestlingentropy/6358525761/sizes/o/in/photostream/" target="_hplink">wrestlingentropy</a>)

  • Baking Soda

    Got dandruff? You're not alone. We put <a href="http://www.stylelist.com/2012/04/27/weird-ways-to-get-rid-of-dandruff_n_1456063.html" target="_hplink">anonymous testers to a 2-week trial of different, natural remedies</a>. The winning treatment? Baking soda. Applied to the scalp as a scrub every-other-day, it eliminated flakes entirely.

Gene responsible for short stature of dwarf pearl millet identified

Mar. 29, 2013 ? While pearl millet is a major food staple in some of the fastest growing regions on Earth, relatively little is known about the drought-hardy grain.

Recently, plant geneticists at the University of Georgia successfully isolated the gene that creates dwarfed varieties of pearl millet. It is the first time a gene controlling an important agronomic trait has been isolated in the pearl millet genome. Their work appeared in the March edition of the journal G3: Genes, Genomics, Genetics.

The dwarf varieties are economically important in the U.S., India and Africa, in particular.

The researchers, led by UGA's Katrien Devos, also were able to trace the dwarf gene to plants bred 50 years ago by Glenn Burton, a UGA plant breeder who worked on the College of Agricultural and Environmental Sciences' Tifton campus.

Knowing which gene controls the dwarfing trait will help plant breeders create more efficient, sustainable varieties of millet that have the short stature some farmers and ranchers want.

"Knowing the actual gene that reduces plant height has allowed us to develop markers that can be used by breeders to screen for the presence of the gene long before the effects of the gene can be visually observed," said Devos, a professor in the College of Agricultural and Environmental Sciences' Institute of Plant Breeding, Genetics and Genomics, housed in the department of crop and soil sciences, and the Franklin College of Arts and Sciences' department of plant biology.

"In the longer term, the knowledge gained in pearl millet will help to develop semi-dwarf lines with high agronomic performance in other cereal crops," she said.

Rajiv K. Parvathaneni, a doctoral student working in Devos' lab, was in charge of tracking down the gene, which works by controlling the flow of the growth hormone auxin through the plant.

He also wanted to understand the mechanism by which the gene controls auxin and to develop plant-breeder-friendly markers that would allow breeders to screen for the dwarfing gene before their plants matured.

The gene that Parvathaneni found affects the downward transport of auxin, which is made in the top part of the plant. If this gene is on, the auxin flows freely, and millet will grow to its full height, about 10 feet. If it is off, the millet plant may only grow to be 3 to 5 feet in height.

Parvathaneni and Devos' team first found which region of the pearl millet's genome contributed to growth and then compared that section to a similar section of DNA from sorghum. Sorghum is a grain related to pearl millet, and a complete map of its genome recently was released by Devos' UGA colleague Andy Patterson.

The comparison revealed that ABCB1, a gene controlling auxin transport and causing reduced plant height in sorghum, was the prime gene candidate controlling pearl millet dwarf stature, Devos said.

Comparative genome analysis, a process in which an unmapped genome is compared to the genome of a similar and more thoroughly described plant genome, is a common method to help identify the functions of specific genes, especially in crops for which little genetic resources are available.

The next step for Devos' team is to work with researchers in other states to understand more fully how auxin transport differs in tall and dwarf millet plants and to verify that ABCB1 is in fact the gene that controls dwarfism.

After Devos and Parvathaneni located the dwarfing gene, they tested pearl millet dwarfs from around the world. All dwarfs caused by a nonfunctional ABCB1 gene have the same mutation as the dwarfs that were first bred by Burton in the 1960s.

Dwarf varieties of pearl millet are not ideal for every planting situation. In Africa, many farmers prefer taller varieties because they use the long stalks for roofing thatch and other applications.

However, where millet is intensively cultivated, dwarf millet allows farmers to harvest the grain with mechanical threshers. Ranchers like dwarf millet as a forage plant because it has a high leaf-to-stem ratio, Devos said.

Knowing more about the plant in general is key to broadening production of the very drought-resistant, hardy grain.

"The crop itself has a future, a bright one-especially in regions where climate change may lead to more erratic rainfall patterns as pearl millet is highly drought tolerant. It already is a popular food crop in semi-arid regions of India and Africa and will likely gain interest from drought-prone regions of the developed world as an alternative to corn in animal feed," Parvathaneni said.

Kenyans await ruling in disputed presidential election

By Edmund Blair and Humphrey Malalo

NAIROBI (Reuters) - Kenya's Supreme Court said on Saturday it would issue its ruling no later than 1400 GMT (10 a.m. EDT) on legal challenges to Uhuru Kenyatta's win in a presidential election seen as a test of democracy, five years after vote disputes triggered widespread bloodshed.

The country's outgoing president called for calm ahead of a decision that will either confirm the victory of Kenya's richest man Kenyatta or force another vote.

Defeated candidate Raila Odinga says the March 4 poll was marred by technical problems and widespread rigging. Both politicians have promised to abide by the court's final word.

"Compatriots: The Supreme Court will deliver its decision not later than 5 p.m. today, Inshallah (God willing)," Chief Justice Willy Mutunga wrote on his Twitter account.

The ruling is expected to address a list of challenges to the result. It was not immediately clear if the timing announced referred to when the court would start reading details of its verdict or the time by which it expected to complete that task.

Police formed a security cordon around the court. Many ordinary Kenyans insist they will not allow a repeat of the violence that killed more than 1,200 people and hammered the economy following a dispute over the last election in 2007.

"We have moved on," said Monica Njagi, 28, owner of an Internet cafe in the port city of Mombasa. "Whatever the ruling, we shall go by it ... We have enough useful lessons from our past."

The peaceful voting in this year's election, and the fact that the dispute is being played out by lawyers not machete-wielding gangs, has already helped repair the image of east Africa's largest economy.

Saturday's ruling will test whether Kenyans trust their reformed judiciary and whether supporters of rival candidates accept the result quietly in a nation where tribal loyalties largely determine political allegiances.

"As the country awaits the Supreme Court ruling which is due this Easter weekend, I call upon all of us to accept the ruling and maintain peace," outgoing President Mwai Kibaki said in a message to mark the Christian Easter holiday.

"ESSENTIAL CONTACTS"

Kenyatta comfortably beat Odinga in terms of votes won, with 50.07 percent versus 43.28 percent, but only narrowly avoided a run-off by just edging above the 50 percent threshold.

Western donors are watching the fate of a regional trade partner and a country they see as vital to stability in a volatile area. They also face a headache if Kenyatta wins.

He is facing charges at the International Criminal Court of crimes against humanity, accused of helping incite the violence after the 2007 vote. Kenyatta denies the charges and has promised to cooperate with the court to clear his name.

Western nations have a policy of having only "essential contacts" with indictees of the court. They say that will not affect dealings with the Kenyan government as a whole, but will worry the issue could drive a long-time ally of the West closer to emerging powers such as China.

Neighboring African states are also keeping a careful eye on proceedings after they were hit by the knock-on effects when vital trade routes through Kenya were shut down five years ago.

Kenya's economy has yet to recover fully from the pummeling it took after the vote violence, with growth rates still yet to return to levels before that bloodshed.

"My worry is that if the court orders another election, tourism will suffer further," said Mohammed Hersi, general manager of the Whitesands hotel, a top Mombasa resort, saying clients were waiting to decide whether to come.

In the Supreme Court's hearing on Friday, the legal teams reviewed results of recounts ordered in 22 of the 33,400 polling stations after Odinga said more votes had been cast than there were registered voters. Both sides said the recounts supported their arguments.

Odinga's team argued that the failures undermined the vote. Rival lawyers said any irregularities or technical hiccups had an insignificant impact and did not change the overall outcome.

Smith leads Louisville to 77-69 victory over Ducks

INDIANAPOLIS (AP) ? Louisville coach Rick Pitino is baffled by Russ Smith.

Not by the star guard himself, who is managing to outdo himself each time he steps on the court. No, Pitino doesn't understand why the rest of the country isn't as impressed with Smith as he ? and every opponent who's faced him ? is.

"I look at (player of the year) lists, and I don't see Russ Smith. I don't see him on the All-America teams," Pitino said. "I'm baffled, just baffled, because it wasn't like he was a Johnny-come-lately. He carried us on his back to a Final Four last year."

And he's one game from doing it again.

With Louisville having a rare off night, Smith lifted the Cardinals to a 77-69 victory over Oregon on Friday that put them in the Midwest Region finals. He matched his career high of 31 points, including seven during what would wind up being the game's decisive run.

Smith is averaging 27 points through the first three games of the tournament.

"Russ Smith is a talented young man," Oregon coach Dana Altman said. "When he got going, we didn't have an answer."

Louisville (32-5) plays Duke on Sunday, the first time Pitino and Mike Krzyzewski have met in a regional final since Christian Laettner's shot in 1992.

The 12th-seeded Ducks managed to make a game of it, though, which is more than most of Louisville's recent opponents can say.

After Louisville went up 66-48 with 9:01 left, Oregon made six straight field goals to close to 70-64. But Kevin Ware scored on a layup and Chane Behanan threw down a monstrous dunk to put the game out of reach.

Ware finished with 11, topping his previous career best by one, and Gorgui Dieng had 10 points, nine rebounds and four blocked shots.

E.J. Singler's 15 points led five Ducks in double figures. But Damyean Dotson had an off night, held without a field goal until five minutes were gone in the second half, and Oregon could never recover from its poor start.

Early foul trouble didn't help, with Johnathan Loyd picking up his third before halftime and Dominic Artis and Carlos Emory playing the last six minutes of the half with two.

"If it wasn't for the beginning, it would have been a completely different game," Loyd said. "We just came out, we weren't ready and we got smacked. If we were playing the way were playing in the second half the whole game, it's a completely different story."

The Cardinals were barely tested in either of their first two games in the NCAA tournament, beating North Carolina A&T by 31 and Colorado State by 26. They set an NCAA tournament record with 20 steals against A&T, outrebounded one of the country's best rebounding teams in Colorado State and left both teams with ugly shooting lines.

But a hacking cough that Smith has had the last few days is making its way around the Louisville team, and it was clear from the start this wasn't going to be another juggernaut performance by the Cardinals.

Peyton Siva spent the last 15:19 of the first half on the bench after picking up his second foul, and Louisville wasn't nearly as stingy on defense as it's been. The Cardinals (13) actually had more turnovers than the Ducks (12), and Oregon is only the third team to shoot 44 percent or better during Louisville's winning streak.

Thanks to Smith, however, the Cardinals finished like they always do lately: with a win.

After Siva went out, Smith hit a 3 to spark a 14-3 run that put Louisville up 24-8. When he capped the spurt with a layup, it was Russ Smith 9, Oregon 8.

"We really dug ourselves a big hole," Singler said. "We tried to figure back as much as possible, but Louisville's a really, really good team. They just played better than us today."

But the Ducks aren't a team that gives in.

After losing six of their last 11 regular-season games, the Ducks have been on a tear. They won the Pac-12 tournament, then upset Oklahoma State and Saint Louis last weekend.

They went on a 16-4 run that cut Louisville's lead to six points, the smallest it had been since the opening minutes of the game.

"We watched film and seen how they run, and we kind of figured out that would happen," Chane Behanan said.

Instead of panicking, the Cardinals regrouped and regained control. After Ware and Behanan's baskets, Smith shot 3-of-4 from the line to seal the win.

"Coach has been telling me to fight through (his cold), fight through it, dig in. My teammates as well," Smith said. "We're fighting through it and just doing whatever we can to get a win."

Researchers engineer plant cell walls to boost sugar yields for biofuels

Mar. 29, 2013 ? When blessed with a resource in overwhelming abundance it's generally a good idea to make valuable use of that resource. Lignocellulosic biomass is the most abundant organic material on Earth. For thousands of years it has been used as animal feed, and for the past two centuries has been a staple of the paper industry. This abundant resource, however, could also supply the sugars needed to produce advanced biofuels that can supplement or replace fossil fuels, providing several key technical challenges are met.

One of these challenges is finding ways to more cost-effectively extract those sugars. Major steps towards achieving this breakthrough are being taken by researchers at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI).

"Through the tools of synthetic biology, we have engineered healthy plants whose lignocellulosic biomass can more easily be broken down into simple sugars for biofuels," says Dominique Loque, who directs the cell wall engineering program for JBEI's Feedstocks Division. "Working with the model plant, Arabidopsis, as a demonstration tool, we have genetically manipulated secondary cell walls to reduce the production of lignin while increasing the yield of fuel sugars."

JBEI is a scientific partnership led by Lawrence Berkeley National Laboratory (Berkeley Lab) whose mission is to advance the development of next generation biofuels that can provide the nation with clean, green and renewable transportation energy that will create jobs and boost the economy. Loque and his research group have focused on reducing the natural recalcitrance of plant cell walls to give up their sugars. Unlike the simple starch-based sugars in corn and other grains, the complex polysaccharide sugars in plant cell walls are locked within a robust aromatic polymer called lignin. Setting these sugars free from their lignin cage has required the use of expensive and environmentally harsh chemicals at high temperatures, a process that helps drive production costs of advance biofuels prohibitively high.

"By embedding polysaccharide polymers and reducing their extractability and accessibility to hydrolytic enzymes, lignin is the major contributor to cell wall recalcitrance," Loque says. "Unfortunately, most efforts to reduce lignin content during plant development have resulted in severe biomass yield reduction and a loss of integrity in vessels, a key tissue responsible for water and nutrient distribution from roots to the above-ground organs."

Lignin has also long posed problems for pulping and animal feed. To overcome the lignin problem, Loque and his colleagues rewired the regulation of lignin biosynthesis and created an artificial positive feedback loop (APFL) to enhance secondary cell wall biosynthesis in specific tissue. The idea was to reduce cell wall recalcitrance and boost polysaccharide content without impacting plant development.

"When we applied our APFL to Arabidopsis plants engineered so that lignin biosynthesis is disconnected from the fiber secondary cell wall regulatory network, we maintained the integrity of the vessels and were able to produce healthy plants with reduced lignin and enhanced polysaccharide deposition in the cell walls," Loque says. "After various pretreatments, these engineered plants exhibited improved sugar releases from enzymatic hydrolysis as compared to wild type plants. In other words we accumulated the good stuff -- polysaccharides -- without spoiling it with lignin."

Loque and his colleagues believe that the APFL strategy they used to enhance polysaccharide deposition in the fibers of their Arabidopsis plants could be rapidly implemented into other vascular plant species as well. This could increase cell wall content to the benefit of the pulping industry and forage production as well as for bioenergy applications. It could also be used to increase the strength of cereal straws, reducing crop lodging and seed losses. Since regulatory networks and other components of secondary cell wall biosynthesis have been highly conserved by evolution, the researchers feel their lignin rewiring strategy should also be readily transferrable to other plant species. They are currently developing new and even better versions of these strategies.

"We now know that we can significantly re-engineer plant cell walls as long as we maintain the integrity of vessels and other key tissues," Loque says.

A paper describing this research in detail has been published in Plant Biotechnology Journal. The paper is titled "Engineering secondary cell wall deposition in plants." Loque is the corresponding author.

After 40 years, Vietnam memories still strong

The last U.S. combat troops left Vietnam 40 years ago Friday, and the date holds great meaning for many who fought the war, protested it or otherwise lived it.

While the fall of Saigon two years later is remembered as the final day of the Vietnam War, many had already seen their involvement in the war finished ? and their lives altered ? by March 29, 1973.

U.S. soldiers leaving the country feared angry protesters at home. North Vietnamese soldiers took heart from their foes' departure, and South Vietnamese who had helped the Americans feared for the future.

Many veterans are encouraged by changes they see. The U.S. has a volunteer military these days, not a draft, and the troops coming home aren't derided for their service. People know what PTSD stands for, and they're insisting that the government takes care of soldiers suffering from it and other injuries from Iraq and Afghanistan.

Below are the stories of a few of the people who experienced a part of the Vietnam War firsthand.

___

'MORE INTERESTED IN GETTING BACK'

Dave Simmons of West Virginia was a corporal in the U.S. Army who came back from Vietnam in the summer of 1970. He said he didn't have specific memories about the final days of the war because it was something he was trying to put behind him.

"We were more interested in getting back, getting settled into the community, getting married and getting jobs," Simmons said.

He said he was proud to serve and would again if asked. But rather than proudly proclaim his service when he returned from Vietnam, the Army ordered him to get into civilian clothes as soon as he arrived in the U.S. The idea was to avoid confrontations with protestors.

"When we landed, they told us to get some civilian clothes, which you had to realize we didn't have, so we had to go in airport gift shops and buy what we could find," Simmons said.

Simmons noted that when the troops return today, they are often greeted with great fanfare in their local communities, and he's glad to see it.

"I think that's what the general public has learned ? not to treat our troops the way they treated us," Simmons said.

Simmons is now helping organize a Vietnam Veterans Recognition Day in Charleston that will take place Saturday.

"Never again will one generation of veterans abandon another. We stick with that," said Simmons, president of the state council of the Vietnam Veterans of America. "We go to the airport. ... We're there when they leave. We're there when they come home. We support their families when they're gone. I'm not saying that did not happen to the Vietnam vet, but it wasn't as much. There was really no support for us."

A RISING PANIC

Tony Lam was 36 on the day the last U.S. combat troops left Vietnam. He was a young husband and father, but most importantly, he was a businessman and U.S. contractor furnishing dehydrated rice to South Vietnamese troops. He also ran a fish meal plant and a refrigerated shipping business that exported shrimp.

As Lam, now 76, watched American forces dwindle and then disappear, he felt a rising panic. His close association with the Americans was well-known and he needed to get out ? and get his family out ? or risk being tagged as a spy and thrown into a Communist prison. He watched as South Vietnamese commanders fled, leaving whole battalions without a leader.

"We had no chance of surviving under the Communist invasion there. We were very much worried about the safety of our family, the safety of other people," he said this week from his adopted home in Westminster, Calif.

But Lam wouldn't leave for nearly two more years after the last U.S. combat troops, driven to stay by his love of his country and his belief that Vietnam and its economy would recover.

When Lam did leave, on April 21, 1975, it was aboard a packed C-130 that departed just as Saigon was about to fall. He had already worked for 24 hours at the airport to get others out after seeing his wife and two young children off to safety in the Philippines.

"My associate told me, 'You'd better go. It's critical. You don't want to end up as a Communist prisoner.' He pushed me on the flight out. I got tears in my eyes once the flight took off and I looked down from the plane for the last time," Lam recalled. "No one talked to each other about how critical it was, but we all knew it."

Now, Lam lives in Southern California's Little Saigon, the largest concentration of Vietnamese outside of Vietnam.

In 1992, Lam made history by becoming the first Vietnamese-American to elected to public office in the U.S. and he went on to serve on the Westminster City Council for 10 years.

Looking back over four decades, Lam says he doesn't regret being forced out of his country and forging a new, American, life.

"I went from being an industrialist to pumping gas at a service station," said Lam, who now works as a consultant and owns a Lee's Sandwich franchise, a well-known Vietnamese chain.

"But thank God I am safe and sound and settled here with my six children and 15 grandchildren," he said. "I'm a happy man."

ANNIVERSARY NIGHTMARES

Wayne Reynolds' nightmares got worse this week with the approach of the anniversary of the U.S. troop withdrawal.

Reynolds, 66, spent a year working as an Army medic on an evacuation helicopter in 1968 and 1969. On days when the fighting was worst, his chopper would make four or five landings in combat zones to rush wounded troops to emergency hospitals.

The terror of those missions comes back to him at night, along with images of the blood that was everywhere. The dreams are worst when he spends the most time thinking about Vietnam, like around anniversaries.

"I saw a lot of people die," Reynolds said.

Today, Reynolds lives in Athens, Ala., after a career that included stints as a public school superintendent and, most recently, a registered nurse. He is serving his 13th year as the Alabama president of the Vietnam Veterans of America, and he also has served on the group's national board as treasurer.

Like many who came home from the war, Reynolds is haunted by the fact he survived Vietnam when thousands more didn't. Encountering war protesters after returning home made the readjustment to civilian life more difficult.

"I was literally spat on in Chicago in the airport," he said. "No one spoke out in my favor."

Reynolds said the lingering survivor's guilt and the rude reception back home are the main reasons he spends much of his time now working with veteran's groups to help others obtain medical benefits. He also acts as an advocate on veterans' issues, a role that landed him a spot on the program at a 40th anniversary ceremony planned for Friday in Huntsville, Ala.

It took a long time for Reynolds to acknowledge his past, though. For years after the war, Reynolds said, he didn't include his Vietnam service on his resume and rarely discussed it with anyone.

"A lot of that I blocked out of my memory. I almost never talk about my Vietnam experience other than to say, 'I was there,' even to my family," he said.

NO ILL WILL

A former North Vietnamese soldier, Ho Van Minh heard about the American combat troop withdrawal during a weekly meeting with his commanders in the battlefields of southern Vietnam.

The news gave the northern forces fresh hope of victory, but the worst of the war was still to come for Minh: The 77-year-old lost his right leg to a land mine while advancing on Saigon, just a month before that city fell.

"The news of the withdrawal gave us more strength to fight," Minh said Thursday, after touring a museum in the capital, Hanoi, devoted to the Vietnamese victory and home to captured American tanks and destroyed aircraft.

"The U.S. left behind a weak South Vietnam army. Our spirits was so high and we all believed that Saigon would be liberated soon," he said.

Minh, who was on a two-week tour of northern Vietnam with other veterans, said he bears no ill will to the American soldiers even though much of the country was destroyed and an estimated 3 million Vietnamese died.

If he met an American veteran now he says, "I would not feel angry; instead I would extend my sympathy to them because they were sent to fight in Vietnam against their will."

But on his actions, he has no regrets. "If someone comes to destroy your house, you have to stand up to fight."

A POW'S REFLECTION

Two weeks before the last U.S. troops left Vietnam, Marine Corps Capt. James H. Warner was freed from North Vietnamese confinement after nearly 5 1/2 years as a prisoner of war. He said those years of forced labor and interrogation reinforced his conviction that the United States was right to confront the spread of communism.

The past 40 years have proven that free enterprise is the key to prosperity, Warner said in an interview Thursday at a coffee shop near his home in Rohrersville, Md., about 60 miles from Washington. He said American ideals ultimately prevailed, even if the methods weren't as effective as they could have been.

"China has ditched socialism and gone in favor of improving their economy, and the same with Vietnam. The Berlin Wall is gone. So essentially, we won," he said. "We could have won faster if we had been a little more aggressive about pushing our ideas instead of just fighting."

Warner, 72, was the avionics officer in a Marine Corps attack squadron when his fighter plane was shot down north of the Demilitarized Zone in October 1967.

He said the communist-made goods he was issued as a prisoner, including razor blades and East German-made shovels, were inferior products that bolstered his resolve.

"It was worth it," he said.

A native of Ypsilanti, Mich., Warner went on to a career in law in government service. He is a member of the Republican Central Committee of Washington County, Md.

A DIFFERENT RESPONSE

Chief Warrant Officer 5 Duane Johnson, who served in Afghanistan and is a full-time logistics and ordnance specialist with the South Carolina National Guard, said many Vietnam veterans became his mentors when he donned a uniform 35 years ago.

"I often took the time, when I heard that they served in Vietnam, to thank them for their service. And I remember them telling me that was the first time anyone said that to them," said Johnson, of Gaston, S.C.

"My biggest wish is that those veterans could have gotten a better welcome home," the 56-year-old said Thursday.

Johnson said he's taken aback by the outpouring of support expressed for military members today, compared to those who served in Vietnam.

"It's a bit embarrassing, really," said Johnson. "Many of those guys were drafted. They didn't skip the country, they went and they served. That should be honored."

ANTI-WAR ACTIVISM

John Sinclair said he felt "great relief" when he heard about the U.S. troop pull-out. Protesting the war was a passion for the counter-culture figure who inspired the John Lennon song, "John Sinclair." The Michigan native drew a 10-year prison sentence after a small-time pot bust but was released after 2 ? years ? a few days after Lennon, Stevie Wonder and others performed at a 1971 concert to free him.

"There wasn't any truth about Vietnam ? from the very beginning," said Sinclair by phone from New Orleans, where he spends time when he isn't in Detroit or his home base of Amsterdam.

"In those times we considered ourselves revolutionaries," said Sinclair, a co-founder of the White Panther Party who is a poet and performance artist and runs an Amsterdam-based online radio station. "We wanted equal distribution of wealth. We didn't want 1 percent of the rich running everything. Of course, we lost."

The Vietnam War also shaped the life of retired Vermont businessman John Snell, 64, by helping to instill a lifetime commitment to anti-war activism. He is now a regular at a weekly anti-war protest in front of the Montpelier federal building that has been going on since long before the start of the wars in Afghanistan and Iraq.

The Haslett, Mich., native graduated from high school in 1966 and later received conscientious objector status. He never had to do the required alternative service because a foot deformity led him to being listed as unfit to serve.

"They were pretty formative times in our lives and we saw incredible damage being done, it was the first war to really show up on television. I remember looking in the newspaper and seeing the names of people I went to school with as being dead and injured every single week," said Snell, who attended Michigan State University before moving to Vermont in 1977.

"Things were crazy. I remember sitting down in the student lounge watching the numbers being drawn on TV, there were probably 200 people sitting in this lounge watching as numbers came up, the guys were quite depressed by the numbers that were being drawn," he said. "There certainly were people who volunteered and went with some patriotic fervor, but by '67 or'68 there were a lot of people who just didn't want to have anything to do with it."

Rapper Gucci Mane denied bond in assault case

ATLANTA (AP) ? Gucci Mane has been denied bond on charges stemming from a fan's accusation that the rapper hit him in the head with a champagne bottle at an Atlanta nightclub.

A fan says the rapper, whose real name is Radric Davis, hit him in the club's V.I.P. area March 16 while he tried to take a picture with Gucci Mane. The fan, James Lettley, says he needed 10 stitches.

Davis was in custody on a charge of aggravated assault with a weapon and appeared in court Wednesday.

The rapper's attorney, Drew Findling, tells WSB-TV (http://bit.ly/XdhFoP ) that Davis' criminal history made it difficult for a judge to set bond. Fulton County jail records show Davis has been arrested 10 times since 2005.

    I am new to this forum so sorry if I do something wrong. I have a RichTextBox1 and RichTextBox2 on my form. RichTextBox1 is for the user to enter some text. RichTextBox2 is not visible on form. I am trying to get the code to take the users text and put in RichTextBox2 to be able to save all the text each time the user hits saved button. I am not sure the best way to go about this. My code below saves the text ok the first time the saved button is hit but when the user adds more text and save again, it is adding the new text and the old text again. I just want it to save the new text only along with the old text but not add the old text again.
    
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click         If RichTextBox1.Text.Length > 0 Then             RichTextBox2.AppendText(RichTextBox1.Text)             If RichTextBox2.Text = RichTextBox1.Text Then                 MessageBox.Show("Text was Saved")             End If          Else             'do nothing         End If     End Sub


    Is This A Good Question/Topic? 0

    Hello donna2002,
    You will need to save the text from textbox2 in a string variable and clear the text from textbox2 before saving the text from textbox1. Thats what it sounds like from the way your explaining it. Try this
    
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click         If RichTextBox1.Text.Length > 0 Then             Dim txt As String = RichTextBox2.Text             RichTextBox2.Clear()             RichTextBox2.Text = RichTextBox1.Text             If RichTextBox2.Text = RichTextBox1.Text Then                 MessageBox.Show("Text was Saved")             End If         End If     End Sub

    Thank you IronRazer for the reply. Yes, that does work but maybe I am not explaining too well. That code does work until the user deletes something or clears his text to start over. I need the RichTextBox2 to always keep the text when the save button is clicked even if the user clears his or does whatever it still needs to keep the old text and add only the new text to RichTextBox2. I am probably not explaining it well. In other words I need both RTB to compare to each other and if there is new text added to RTB1 then add only that text to RTB2 along with what is already in RTB2. I have tried different ways but keep getting RTB2 with too much text adding the old and new text together and having duplicates of the same text when the user only entered it once. I hope that clears it up some. I am not good explaining myself.

    Spat between two Dutch companies sparks record-breaking 300Gbps DDoS attack

    March 28 (Reuters) - Rory McIlroy, playing for the first time since losing his world number one ranking earlier this week, got off to a shaky start at the Houston Open on Thursday where he dropped three shots over his opening eight holes. The 23-year-old Northern Irishman, who was replaced atop the world rankings by Tiger Woods this week, struggled to find his rhythm on an ideal day for low scoring at the Redstone Golf Club in Humble, Texas. He bogeyed the par-four second hole and made a double-bogey seven on the eighth hole to limp to the turn at three-over. ...
