La Salle, James Madison advance from First Four

DAYTON, Ohio (AP) ? Guards, guards everywhere. And they can shoot.

La Salle gets to take its uncharacteristic approach ? not much size but lots of shots and lots of points ? back to a city that has a little nostalgia for the Explorers.

Tyrone Garland led the guard-driven offense with 22 points, and the Explorers wrapped up the NCAA tournament's First Four by getting the better of an old-fashioned shootout, beating Boise State 80-71 on Wednesday night.

It was a notable moment for the 13th-seeded Explorers (22-9), who hadn't even been in the tournament for 21 years. Now, they head to Kansas City to play fourth-seeded Kansas State on Friday.

Kansas City? That's the place where they beat Bradley to win the national title in 1954.

"Unbelievable tradition here," coach John Giannini said. "I think people have tended to have forgotten what a basketball power La Salle was for over four decades. So it's a big deal. It's a big deal to re-establish that. It's a big deal for people who attended La Salle and love La Salle, who had great basketball, and certainly they've longed for that."

In the first game, A.J. Davis stepped in for James Madison's suspended leading scorer and had 20 points, leading the Dukes to a 68-55 win over LIU Brooklyn.

James Madison (21-14), which won its first NCAA tournament game in 30 years, next takes on top-seeded Indiana, also in Dayton.

The Dukes were without suspended starter Rayshawn Goins for the first half, but built a big lead. After the Blackbirds (20-14) rallied to take a brief lead, the Dukes surged again to win going away by closing the game on a 10-2 run.

Davis opened the game with an emphatic 3 as if to say this was his time. And he didn't let up.

"Coach said, 'Don't do anything outside of your character, just be humble and play your game,'" Davis said. "While Rayshawn was sitting out, a couple of guys came off the bench and stepped up for us."

Charles Cooke, who hadn't scored in three of his last four games, added 15 points and defensive specialist Andre Nation added 14 for the Dukes, who were winless in the NCAA tournament since 1983.

Jamal Olasewere had 20 points and 10 rebounds and C.J. Garner 16 points for the Blackbirds, who have lost in their first game in each of their six trips to the tournament, including the last three years.

Goins, JMU's leading scorer (12.7) and rebounder (7.4), was suspended for the first half following a weekend arrest. Police in Harrisonburg, Va., said they were called to break up a party early Sunday morning and Goins was shouting obscenities at them. He looked out of synch when he got into the game, but later added four points in the decisive run that put the game out of reach.

Now, the Dukes have taken a step toward reminding people how dangerous they used to be.

Lou Campanelli coached the Dukes to mammoth NCAA upsets over Georgetown in 1981, Ohio State in 1982 and West Virginia in 1983. The 1982 team lost to eventual national champion North Carolina ? led by Michael Jordan, James Worthy and Sam Perkins ? 52-50 in the final minute.

But James Madison's last appearance came with Lefty Driesell prowling the sideline in 1994.

Coach Matt Brady figured his Dukes have one huge advantage over Indiana since they've already played on the court. And they're already in Dayton.

"I'm hoping they haven't arrived in town just yet and they get here right before the game starts," he said with a laugh.

La Salle was in a mood to remember history, too. And, maybe to make a little more as well.

It'll be tough to play any better on offense in KC than they did Wednesday night.

Ramon Galloway, one of the Atlantic 10's top scorers, added 21 points in a fast-paced offense that did pretty much whatever it wanted. The Explorers shot a season-high 63 percent from the field ? 16 of 22 in the second half.

Garland went 9 of 11 from the field ? his best shooting game of the season ? and the Explorers were 11 of 21 behind the arc.

"It's an unbelievable feeling," Garland said. "When I came here, coach told me I could help him win games and get him to the next step."

Thirteenth-seeded Boise State (21-11) got its first at-large bid and was looking for the first NCAA tournament win in its history. The Broncos were up to it in a game of try-to-top-this shooting, falling to 0-6 in the tournament.

Anthony Drmic had a game-high 28 points for the Broncos, who shot 49 percent but trailed most of the way.

"They shot incredible tonight," Drmic said. "All credit to them."

Panel: Thumbs down on anthrax vaccine test in kids

WASHINGTON (AP) ? Don't look for testing of the anthrax vaccine to begin in children any time soon.

Controversy arose last year as experts debated whether such studies should be done to learn how to treat children in case of a bioterror attack.

But a presidential commission says the government would have to take multiple steps ? including more safety research in young adults ? before it would be ethical to consider tests in children.

"The safety of our children is paramount, and we have to get this precisely right," said Dr. Amy Gutmann, who chairs the Presidential Commission for the Study of Bioethical Issues, which released its report Tuesday.

More than a decade after the anthrax attacks, the government has a multibillion-dollar stockpile of drugs and vaccines to fight an array of threats. There's no information on whether those so-called countermeasures would work in children like they're expected to help their parents, or even what dose to use. Yet if a large attack were to occur, children undoubtedly would receive those untested products.

Worried about how to handle an emergency, a government advisory group recommended studying the anthrax vaccine in children if independent ethics experts agreed it could be done appropriately. The Obama administration put that question to the panel.

Tuesday's answer: Children don't gain any benefit from pre-attack research with the anthrax vaccine or other countermeasures. So the panel said such studies would be ethical only if they presented no more than minimal risk to participants ? like the risk from a routine medical check-up. Determining that would require, among other things, more testing in adults, the panel added. Something that proved safe in 18-year-olds, for example, might be a candidate to study next in 16- and 17-year-olds.

However, the government should plan now for how it would study children who receive those treatments in the event of an attack, the panel said.

The Health and Human Services Department, which requested the advice, said it would review the findings.

Ex-Elmo puppeteer faces new sex, drug claims

Updated, 2:40 p.m. ET: Kevin Clash, the ex-Elmo puppeteer who previously faced allegations of sex abuse, is once again at the center of a lawsuit. The man behind the iconic "Sesame Street" character is named in a sexual abuse lawsuit filed by Sheldon Stephens, who was the first individual to accuse Clash of abuse in 2012.

Stephens claims in a new complaint filed Monday in Middle District Court of Pennsylvania that he and Clash met in 2004 through a social networking event for models and actors. According to a press release sent by Stephens' attorney Jeff Herman, the complaint includes accusations that Clash and Stephens began having sexual intercourse when Stephens was 16. It details an occasion when Stephens was still 16 and Clash hosted a "crystal meth sex party" at his apartment. The complaint also accuses Clash of doing meth at that party, giving the drugs to Stephens, and engaging in sexual contact with the then-teenager.

Michael Berger, an attorney for Clash, issued a statement Tuesday calling the lawsuit "meritless" and "barred by the statute of limitations." In the statement, Berger writes that Stephens has "already admitted in writing that he had 'an adult consensual relationship' with Mr. Clash. Mr Clash continues to deny any wrongdoing, and we intend to defend this case forcefully."

Clash resigned from Sesame Workshop in 2012.

Leaping lunar dust: Electrically charged dust near shadowed craters can get lofted above Moon's surface

Mar. 18, 2013 ? Electrically charged lunar dust near shadowed craters can get lofted above the surface and jump over the shadowed region, bouncing back and forth between sunlit areas on opposite sides, according to new calculations by NASA scientists.

The research is being led by Michael Collier at NASA's Goddard Space Flight Center, Greenbelt, Md., as part of the Dynamic Response of the Environment At the Moon (DREAM) team in partnership with the NASA Lunar Science Institute (NLSI), managed at NASA's Ames Research Center, Moffett Field, Calif.

"The motion of an individual dust particle is like a pendulum or a swing," says Collier. "We predict dust can swarm like bees around a hive over partially shaded regions on the moon and other airless objects in the solar system, such as asteroids. We found that this is a new class of dust motion. It does not escape to space or bounce long distances as predicted by others, but instead stays locally trapped, executing oscillations over a shaded region of 1 to 10 meters (yards) in size. These other trajectories are possible, but we now show a third new motion that is possible." Collier is lead author of a paper on this research published October 2012 in Advances in Space Research.

This effect should be especially prominent during dusk and dawn, according to the team, as regions become partially illuminated while features like mountains and crater rims cast long shadows.

"The dust is an indicator of unusual surface electric fields," says William Farrell of NASA Goddard, a co-author on the paper and lead of the NLSI DREAM team. "In these shaded regions, the surface is negatively charged compared to the sunlit regions. This creates a locally complex, larger electric field with separate positively and negatively charged regions, called a dipole field, over the shaded region. The dust performed its swinging motion under the influence of this dipole. Such a surface process occurring on the moon at the line where night transitions to day, called the terminator, might also occur at small bodies like asteroids. It might be a fundamental process occurring at airless rocky bodies."

There is evidence that dust actually moves this way over the lunar surface. "There are hints for this type of dust swarm in Surveyor images. A twilight was observed over the landed platforms during dusk and dawn. This was surprising at first because the moon does not have a dense enough atmosphere to scatter light when the sun is below the horizon. It was long considered to be light scattered from lifted dust. This model suggests the dust is really leaping or swarming overtop a large number of shaded regions that would exist along the lunar dusk/dawn line, called the lunar terminator. It's a natural fit. Charged lunar dust transport is also believed responsible for the Apollo 17 Lunar Ejecta and Meteorites (LEAM) experiment's observation of highly charged dust near the terminator," adds Collier.

To our eyes, the moon has no apparent activity and seems dead. However, because it has almost no atmosphere, the moon is exposed to the solar wind, a thin stream of electrically conducting gas called plasma blown off the surface of the sun at around a million miles per hour. The effects of sunlight and the solar wind generate a bustle of unseen commotion at the moon. On the day-lit side, sunlight knocks negatively charged electrons off the surface, giving it a positive charge. On the night side or in shadow, electrons from the solar wind rush in, giving the surface a negative charge.

The exact mechanism for launching lunar dust is not uniquely known. Micro-meteoroid impacts can transfer energy to the surface to launch particulates. Also, a rough surface has small, localized concentrations of electric fields that could lift dust electrostatically from the surface. The pendulum motion then happens because sunlit areas on the moon tend to get positively charged, while shaded areas become negatively charged. Since like charges repel each other, a positively charged dust grain in a sunlit area gets pushed away from the positively charged surface. If there were no negatively charged area nearby, the dust grain would rise straight up. However, since opposite charges attract, the positively charged dust gets pulled toward the negatively charged crater floor, bending its path over the crater. Dust launched from the sunlit area with just the right speed will pass over the shaded floor of the crater to the sunlit area on the other side, where the positively charged surface there will reflect it back over the crater again. When many particles do this, the model predicts there should be a swarm or canopy of dust over the crater.

If there were no complications, the particle could continue to bounce between sunlit areas on opposite sides of the crater indefinitely. However, in reality, things like differences in crater rim height, roughness on the crater floor, and interference from the solar wind that weakens the electric field produced by the surface charges can alter the particle's path. These perturbations cause the dust to eventually either fall into the crater or be launched away. "This model provides a natural explanation for the observation of dust ponds inside craters on the asteroid Eros," says Collier.

"Calculating how these complications will affect the path of a dust particle on the moon and around asteroids are good areas for future research," says Collier. "Additionally, we're not sure how many particles get charged and move like this -- is it something like one in a thousand, one in a million, or one in a billion? We'd like to do more studies to see how likely it is that a particle will behave this way. Since most of the lunar surface is covered in dust, even one in a billion would still be significant." The team is also planning on examining Apollo-era images to evaluate possible evidence for dust canopies over shadowed craters.

The team includes Collier, Farrell, and Timothy Stubbs, also at NASA Goddard. The research was funded by the NLSI.

Self-assembled nanostructures enable a low-power phase-change memory for mobile electronic devices

Mar. 18, 2013 ? Nonvolatile memory that can store data even when not powered is currently used for portable electronics such as smart phones, tablets, and laptop computers. Flash memory is a dominant technology in this field, but its slow writing and erasing speed has led to extensive research into a next-generation nonvolatile memory called Phase-Change Random Access Memory (PRAM), as PRAM's operating speed is 1,000 times faster than that of flash memory.

PRAM uses reversible phase changes between the crystalline (low resistance) and amorphous (high resistance) state of chalcogenide materials, which corresponds to the data "0" and "1," respectively. Although PRAM has been partially commercialized up to 512 Mb by Samsung Electronics Co., Ltd., its writing current should be decreased by at least one-third of its present level for the mass production of mobile electronics applications.

A team of Professors Keon Jae Lee and Yeon Sik Jung in the Department of Materials Science and Engineering at KAIST has developed phase-change memory with low power consumption (below 1/20th of its present level) by employing self-assembled block copolymer (BCP) silica nanostructures.

BCP is the mixture of two different polymer materials, which can easily create self-ordered arrays of sub-20 nm features through simple spin-coating and plasma treatments. PRAM can lower switching power consumption by making the contact area smaller between the heating layer and phase change materials. Professor Lee's team successfully decreased the size of the contact area and the level of power consumption by incorporating self-assembled silica nanostructures on top of conventional phase-change materials. Interestingly, these self-assembled nanomaterials are able to reduce power much more than expected with localized nano-switching mechanisms.

Professor Keun-Jae Lee said, "This is a very good example that self-assembled, bottom-up nanotechnology can actually enhance the performance of electronic devices. We also achieved a significant power reduction through a simple process that is compatible with conventional device structures and existing lithography tools."

The research team is currently investigating self-assembled BCP applications for resistive random access memory and flexible electronic devices.

DUBLIN (AP) ? Never mind the fickle Irish weather. A chilly, damp Dublin celebrated St. Patrick's Day with artistic flair anyway Sunday as the focal point for a weekend of Irish celebrations worldwide.

More than 250,000 revelers braved the occasionally snowy, sleety skies to line the streets for the traditional holiday parade, a 3-kilometer (2-mile) jaunt through the city's heart involving performers from 46 countries.

Unusually, 8,000 tourists in town for the festivities led this year's procession in a "people's parade." Many donned leprechaun costumes or deployed banners and flags of their home nations or U.S. states, with the Texans making the biggest impression as they sported "Happy St. Paddy's Day, Y'All!" T-shirts.

One marcher, a 22-year-old engineer from Calgary, Canada, defiantly showed it wasn't so nippy at all ? by doing the hour-long walk shirtless, with only a painted-on shamrock covering his chest.

"It's not cold!" Oliver Feniak declared as he, like many in the leisurely paced 2 1/2-hour parade, stopped to shake hands with onlookers standing five-deep on O'Connell Bridge spanning the River Liffey.

Sunday's decision to put tourists in the vanguard was connected to a year-long tourism promotion called The Gathering that is organizing hundreds of clan reunions nationwide in hopes of boosting the economy. That's sorely needed in an Ireland struggling with 14 percent unemployment, heavy emigration and a household-debt crisis following the 2008 collapse of its Celtic Tiger boom.

St. Patrick's Day always marks the start of Ireland's full-court press for tourists. Since 1997 Dublin has expanded the holiday into a multi-day festival featuring special children's playgrounds, street amusement parks, concerts and walking tours. Irish President Michael D. Higgins is hosting a nationally televised TV show Monday night featuring many of Ireland's top artists and musicians, including Bono and Nobel-winning poet Seamus Heaney.

"We cherish the creativity, community spirit and rich culture for which we, as a nation, are renowned," Higgins said in a speech after the parade. "I have said on many occasions that while the experience of the so-called Celtic Tiger failed to live up to the best versions of Irishness, we have not been failed by our artists. In fact, our artists are a huge moral resource and great reputational asset for Ireland."

St. Patrick's Day is being marked in skylines across the world as part of a global campaign to floodlight landmarks green at night. This year the pyramids of Giza, the leaning tower of Pisa, Niagara Falls, and the Christ the Redeemer statue overlooking Rio are among dozens of iconic spots going green for the occasion.

While tens or thousands of foreigners have made a beeline for Dublin, practically the entire Irish government has gone the other direction, sending 19 ministers to 21 countries to capitalize on a marketing opportunity unique among nations.

Prime Minister Enda Kenny marched in Saturday's biggest U.S. parade in New York and is scheduled to meet President Obama at the White House on Tuesday, when the U.S. political establishment marks the Irish holiday.

It hasn't all gone smoothly. The government deputy leader, Foreign Minister Eamon Gilmore, caused diplomatic waves in Atlanta, Georgia, by snubbing the second-biggest American parade in nearby Savannah ? because, Gilmore said, he didn't want to attend a dinner hosted by an Irish-American group that bans women from attending.

Most of Irish-America marked the holiday a day early, reflecting the view that such a notoriously boozy holiday shouldn't happen on a Sunday. But the Irish diaspora in most of the rest of the world stuck to marking St. Patrick's Day on March 17 as usual.

Many of Sunday's revelers suggested they were in Dublin specifically to soak up the pub atmosphere.

"We came all the way from Kansas City to drink some Guinness!' declared one banner on the parade route displayed by John Mullen, a 46-year-old lawyer, and his 17-year-old son Jack.

The senior Mullen, whose roots lie in the western county of Mayo, said he and his boy actually were golfing their way through Ireland, not drinking. He said the key to enjoying Ireland was to soak up the locals' exceptionally good conversation regardless of the foul weather.

"Yesterday we got rained on, sleeted on, snowed on as we golfed. There was even some sun here and there. It was four seasons in one round," Mullen said. "People back home say I've got the gift of the gab, but I've got no game here. The conversations here are magnificent. But you sometimes wonder how you've ever going to get out of them!"

In the world's first major St. Patrick's party Sunday, about 30,000 spectators soaked up the sun as Sydney's Irish-Australians paraded through the city. Australia always marks St. Patrick's Day on a Sunday. After the event, partiers rallying at the city's Hyde Park saw 45 Irish men and women receive Australian citizenship. That's increasingly common as tens of thousands of Irish job-seekers have made Australia a favored new home while Ireland's own economy remains in the doldrums.
