Creationism Case: John Freshwater Lawyers Spar With Mount Vernon School Board In Ohio Bible Case

COLUMBUS, Ohio ? In a heated hour of arguments, Ohio Supreme Court justices sparred with lawyers Wednesday over the extent to which a now-fired public school science teacher had the right to push his personal religious beliefs in class.

A lawyer for the school board that dismissed John Freshwater in 2011 said he waved a Bible at his students, handed out religious pamphlets and espoused creationism in his evolution lessons.

Freshwater violated the constitutional separation between church and state and was rightfully fired, said David Smith, an attorney for the Mount Vernon School Board.

"You can't teach evolution from a Christian perspective" without violating constitutional protections against government establishment of religion, he said.

Freshwater's attorney, Rita Dunaway, said accounts of Freshwater's class conduct were exaggerated and that the instructor was exercising his academic freedom to explore controversial ideas.

"A Bible on a desk hidden amongst other clutter does not a religious display make," she said.

Dunaway said Freshwater had a laudable teaching record and his students scored well on standardized science tests.

Freshwater was dismissed in 2011 after investigators reported he preached Christian beliefs in class when discussing topics such as evolution and homosexuality and was insubordinate in failing to remove the Bible from his classroom.

Justices appeared perplexed, at times irritated, about what lawyers believed was the legal issue before them.

Justice Paul Pfeifer was incredulous when Smith argued that Freshwater's evolution class wouldn't have been covered under the school district's controversial-issues policy.

"So there's nothing controversial about evolution. It is a theory, isn't it?" he said.

Freshwater also had been accused of using a science tool to burn students' arms with the image of a cross, but that allegation was resolved and was not a factor in his firing.

Justices wanted to know Wednesday whether that incident played a role in Freshwater's dismissal. Smith speculated that attention surrounding that incident was what prompted the school board's investigation into Freshwater's 21-year career.

In its review, the board concluded Freshwater had used a high-frequency generator, which other teachers have used to demonstrate electrical current, to burn a cross onto a student's arm. The cross lasted a few weeks.

The student's family settled a federal lawsuit against the district in an effort to move on.

In his dismissal case, Freshwater is getting legal backing from the Charlottesville, Va.-based Rutherford Institute, a civil liberties group. Science education and humanist and secular groups have joined the side of the school board.

The school board argues that as far back as 1994, a middle school principal told Freshwater to stop distributing an "Answers in Genesis" pamphlet, which contained information about a creationist organization's seminar, according to a filing by board attorneys asking the court to uphold Freshwater's firing.

Freshwater also used a handout titled "Survival of the Fakest" to teach his students to doubt science, the board's attorneys said.

Two lower courts previously upheld Freshwater's dismissal.

At the back of the courtroom Wednesday, 17-year-old Esther Sorg and 18 other students from Wilmington Christian Academy about an hour southwest of Columbus were listening in as part of a school field trip.

Sorg said her science classes include evolution, and it seems public school classes could include the creationist perspective without harm.

"My eighth-grade science class was taught from a Christian perspective, but we discussed evolution as well," she said. "I thought that was good because I wanted to know what the current theories were."

Actor Dale Robertson dies in California hospital

OKLAHOMA CITY (AP) ? Dale Robertson, an Oklahoma native who became a star of television and movie Westerns during the genre's heyday, died Tuesday. He was 89.

Robertson's niece, Nancy Robertson, said her uncle died at Scripps Memorial Hospital in La Jolla, Calif., following a brief illness.

Dale Robertson had bit parts in films including "The Boy with the Green Hair" and the Joan Crawford vehicle "Flamingo Road" before landing more high-profile roles such as Jesse James in "Fighting Man of the Plains."

In the 1950s, he moved into television, starring in series such as "Tales of Wells Fargo" (1957-62), "Iron Horse" (1966) and "Death Valley Days" (1968-70).

Robertson continued to work in TV in the 1970s, and in the 1980s he landed roles in the popular night-time soap operas "Dallas" and "Dynasty."

In 1993, he took what would be his final role, as Zeke in the show "Harts of the West," before retiring from acting to spend more time at his ranch in Yukon, Okla., where he lived until moving to the San Diego area in recent months, Nancy Robertson said.

Dale Robertson would want to be remembered as a father, a grandfather and an Oklahoman, she said.

"He came back a lot when he was in Hollywood, and he came back (to Oklahoma) after retiring," she said.

"I remember him as a larger-than-life fellow," she said. "When he was in town it was always very exciting. It always meant something magical was going to happen," such as another actor or performing artist accompanying him on his visits.

Born Dayle Lymoine Robertson to Melvin and Vervel Robertson in Harrah, on July 14, 1923, Robertson attended Oklahoma Military College at 17 and boxed in professional prize fights to earn money.

He joined the U.S. Army and fought in North Africa and Europe during World War II. Robertson was wounded twice and awarded the Bronze and Silver Stars and the Purple Heart.

While stationed at San Luis Obispo, Calif., he had a photograph taken for his mother. A copy of the photo displayed in the photo shop window attracted movie scouts, and the 6-foot-tall, 180-pound Robertson soon was on his way to Hollywood.

Will Rogers Jr., son of fellow Oklahoma-born actor and writer Will Rogers, once told Robertson to avoid formal training and keep his own persona.

Robertson received the Golden Boot Award in 1985, and was inducted into the Hall of Great Western Performers and the Cowboy Hall of Fame in Oklahoma City.

He was married several times, most recently in 1980 to Susan Robbins, who survives him along with two children.

Nancy Robertson said her uncle will be cremated and that a memorial service will be held in a few weeks.

Work on a high-conductivity material demonstrates the role of oxygen ions in enhancing their capabilities

Yttria stabilized zirconia, also known as YSZ, is a material of great interest because of its relatively high oxygen-ion based conductivity. In particular, it finds applications in electrochemical devices, such as solid oxide fuel cells and oxygen sensors. In a study published in EPJ B, Kia Ngai, from the University of Pisa in Italy, and colleagues from the Complutense University in Madrid, Spain, devised a model of the oxygen-ion dynamics that contribute to the conductivity of YSZ.

The problem is that fuel cells currently operate above 700 C, which strongly limits their use. Understanding oxygen-ion diffusion is key to helping lower operating temperature down to room temperature. Previous attempts to do so were done with the so-called coupling model (CM), describing simple physical concepts related to ion-ion interaction. This helped uncover the importance of ion-ion correlation in limiting long-range ion mobility, and thus conductivity.

The trouble is that experiments show that ionic conductivity in YSZ requires an activation energy that is much higher than that supplied by computer simulations describing independent ion hopping. Relying on the CM model, the authors first established a quantitative description of the ion dynamics in YSZ. Then they compared the predictions of the CM with experimental results and with simulations, particularly those of nanometric-scale thin films, published in the last ten years.

Thus, in their model, they established the connection between the level of the energy barrier for independent ion-hopping simulations and the level of activation energy measured experimentally for long-range movement of oxygen ions. In addition, they attributed an increase of the conductivity in nanometers-thick YSZ films to a decrease in the ion-ion correlations. This model could also be used to study the conductivity relaxation of so-called molten, glassy and crystalline ionic conductors and ambient temperature ionic liquids.

(AP Photo/Robert S. Beckett)

LAS VEGAS (AP) ? Police said Monday they have a warrant for a 26-year-old ex-convict identified as the prime suspect in a shooting and fiery crash that killed three people last week on the Las Vegas Strip.

"We can say with certainty that Ammar Harris is the suspect who fired the fatal shots," Las Vegas police Capt. Chris Jones told reporters at an afternoon update about a manhunt that he said would be advertised on southern Nevada billboards.

Police previously released a photo of Harris taken after his arrest last year in Las Vegas in a 2010 prostitution case. It showed Harris with tattoos on his right cheek and words on his neck above an image that appeared to depict an owl with blackened eyes. Jones said Harris should be considered armed and dangerous.

Jones said investigators were looking everywhere Harris had lived in the past. He wasn't specific.

Public records show that Harris previously lived in South Carolina and Georgia, and told a police officer when he was arrested in Miami Beach last December that he had lived in Florida for about a year.

Harris was convicted in 2004 in Orangeburg, S.C., of felony possession with intent to sell a stolen pistol, Jones said. The conviction was not in California, as police said earlier.

Clark County District Attorney Steve Wolfson attended the news conference and said afterward that the case was getting top priority from prosecutors and he hoped Harris would turn himself in. He said the warrant was issued Friday.

"If Mr. Harris is listening, I would urge him to surrender," Wolfson said.

Harris used the name Ammar Asim Faruq Harris when he was arrested last May in Las Vegas in the June 2010 case. He was charged with robbery, sexual assault, kidnapping and coercion with a weapon.

Las Vegas police also sought pandering by force and ex-felon in possession of concealed weapon charges stemming from allegations that Harris was a pimp and attacked a woman.

Court records show the case was dismissed last June. The prosecutor and a public defender who handled the case didn't immediately respond to messages Monday.

In Miami Beach, Harris was arrested Dec. 7 after he was accused of driving a silver 2006 Hummer H3 the wrong way on a congested street at 2 a.m. The arresting officer said Harris produced a Florida state identification card and provided a Miami address. The status of the case in Miami-Dade courts was unclear Monday.

In Atlanta, Harris was arrested in June 2004 on a felony marijuana possession with intent to distribute charge. According to court records, he pleaded guilty to a misdemeanor marijuana possession charge and was sentenced to three months in jail.

Fulton County jail records show Harris spent about two weeks in jail in February 2008 after a misdemeanor battery arrest. The outcome of that case was not immediately clear Monday.

In Las Vegas, investigators say Harris was driving a black Range Rover SUV when he fired shots into a Maserati before dawn Thursday, killing an aspiring rapper and causing a crash that killed two people when the Maserati slammed into a taxi that exploded in a fireball at the heart of the Strip.

Police said several other people were with Harris in the SUV as it fled the scene of the six-vehicle, chain-reaction crash on Las Vegas Boulevard near the Bellagio, Caesars Palace, Bally's and Flamingo resorts.

Jones and police homicide Lt. Ray Steiber said they were confident that Harris was the only shooter. They didn't say whether police intend to prosecute anyone else in the SUV.

But, "To anyone who is aware of his location or is assisting Ammar Harris in any way, you will be arrested and prosecuted," Jones said. "You may think you're being a friend, but keep in mind Ammar Harris is wanted for the murder of three citizens."

The SUV was the focus of an intense search before it was found Saturday parked in the garage of a gated apartment complex just a couple of blocks east of the Strip. Harris wasn't found at a nearby apartment where he was believed to have been living.

Kenneth Wayne Cherry Jr. was mortally wounded when the dark gray Maserati he was driving was peppered by gunfire from the SUV. Taxi driver Michael Boldon, 62, of Las Vegas, and passenger Sandra Sutton-Wasmund, 48, of Maple Valley, Wash., died in the taxi.

Police say the triple homicide stemmed from an altercation between Cherry and Harris in a valet area of the upscale Aria resort a block south of the crash scene at Las Vegas Boulevard and Flamingo Road.

A passenger in the Maserati was wounded in the arm, and four people from four other vehicles were treated for non-life-threatening injuries after the crash.

Las Vegas police sought help during last week's search for the Range Rover from local and federal authorities in Nevada and neighboring states of Arizona, California and Utah.

The Magazine adds web subscriptions, full article sharing

Marco Arment's The Magazine is widely regarded as the best thing to happen to iOS' Newsstand to date, and now Arment is expanding it to take on the web as well. That includes both online subscriptions in addition to iOS, and the ability to share the full text of an article. Here's how Arment describes it on Marco.org:

[You] can now subscribe to The Magazine on the web, and you can sync subscriptions between the app and the website so you don?t need to pay twice. (I even implemented a crazy passwordless login system. Check it out. You can create an account on the site without subscribing if you want to see it.)

Non-subscribers can now also read one article a month, and even Instapaper that article if they like.

It?s a lot like the New York Times paywall, but with a limit of one free article per month. (We only publish about 11 articles per month, and we don?t run ads like they do, so higher limits would be problematic.)

Since launch, the quality of The Magazine's articles has remained top notch even as the scope has grown considerably. Informative, touching, entertaining, heart breaking, inspiring, and enlightening, they're delivered not only to your iPhone and iPad every two weeks, but now to your browser as well.

If you haven't checked The Magazine out already, check it out now. And for more on why Arment has made the changes he did, check out the rest of his post.

Ronda Rousey was more worried about her sports bra staying on than being submitted

During their main event bout at UFC 157, Liz Carmouche took Ronda Rousey's back and had her in a neck crank. The crank was so deep that Rousey inadvertently bit Carmouche's arm. But Rousey told the Fuel TV aftershow that she was never worried about submitting to Carmouche. Instead, she was concerned about a wardrobe malfunction.

?On the ground I feel so comfortable in every position, so I never feel in danger and I take a lot of risks. I felt fine with her on my back. I was more concerned with my sports bra staying on while she was choking me because I felt safe and in control," Rousey said.

Rousey won a bronze medal in the 2008 Olympics in judo, so submissions have been part of her life for a long time. In fact, Rousey has spoken often about how her mother taught her judo by waking her up with an armbar. While the neck crank was uncomfortable, it wasn't new.

What is new is having to worry about a sports bra not doing its job. Come on, sports bra. You had one job. Thankfully, it did stay in place, and Rousey went on to submit Carmouche seconds before the end of the first round.

Laser mastery narrows down sources of superconductivity

Feb. 24, 2013 ? Identifying the mysterious mechanism underlying high-temperature superconductivity (HTS) remains one of the most important and tantalizing puzzles in physics. This remarkable phenomenon allows electric current to pass with perfect efficiency through materials chilled to subzero temperatures, and it may play an essential role in revolutionizing the entire electricity chain, from generation to transmission and grid-scale storage. Pinning down one of the possible explanations for HTS -- fleeting fluctuations called charge-density waves (CDWs) -- could help solve the mystery and pave the way for rapid technological advances.

Now, researchers at the Massachusetts Institute of Technology and the U.S. Department of Energy's Brookhaven National Laboratory have combined two state-of-the-art experimental techniques to study those electron waves with unprecedented precision in two-dimensional, custom-grown materials. The surprising results, published online February 24, 2013, in the journal Nature Materials, reveal that CDWs cannot be the root cause of the unparalleled power conveyance in HTS materials. In fact, CDW formation is an independent and likely competing instability.

"It has been difficult to determine whether or not dynamic or fluctuating CDWs even exist in HTS materials, much less identify their role," said Brookhaven Lab physicist and study coauthor Ivan Bozovic. "Do they compete with the HTS state, or are they perhaps the very essence of the phenomenon? That question has now been answered by targeted experimentation."

Custom-grown Superconductors

Electricity travels imperfectly through traditional metallic conductors, losing energy as heat due to a kind of atomic-scale friction. Impurities in these materials also cause electrons to scatter and stumble, but superconductors can overcome this hurdle -- assuming the synthesis process is precise.

For this experiment, Bozovic used a custom-built molecular beam epitaxy system at Brookhaven Lab to grow thin films of LaSrCuO, an HTS cuprate (copper-oxide) compound. The metallic cuprates, assembled one atomic layer at a time, are separated by insulating planes of lanthanum and strontium oxides, resulting in what's called a quasi-two-dimensional conductor. When cooled down to a low enough temperature -- less than 100 degrees Kelvin -- strange electron waves began to ripple through that 2D matrix. At even lower temperatures, these films became superconducting.

Electron Sea

"In quasi-two-dimensional metals, low temperatures frequently bring about interesting collective states called charge-density waves," Bozovic said. "They resemble waves rolling across the surface of a lake under a breeze, except that instead of water, here we actually have a sea of mobile electrons."

Once a CDW forms, the electron density loses uniformity as the ripples rise and fall. These waves can be described by familiar parameters: amplitude (height of the waves), wavelength (distance between waves), and phase (the wave's position on the material). Detecting CDWs typically requires high-intensity x-rays, such as those provided by synchrotron light sources like Brookhaven's NSLS and, soon, NSLS-II. And even then, the technique only works if the waves are essentially frozen upon formation. However, if CDWs actually fluctuate rapidly, they may escape detection by x-ray diffraction, which typically requires a long exposure time that blurs fast motion.

Measuring Rolling Waves

To catch CDWs in action, a research group at MIT led by physicist Nuh Gedik used an advanced ultrafast spectroscopy technique. Intense laser pulses called "pumps" cause excitations in the superconducting films, which are then probed by measuring the film reflectance with a second light pulse -- this is called a pump-probe process. The second pulse is delayed by precise time intervals, and the series of measurements allow the lifetime of the excitation to be determined.

In a more sophisticated variant of the technique, largely pioneered by Gedik, the standard single pump beam is replaced by two beams hitting the surface from different sides simultaneously. This generates a standing wave of controlled wavelength in the film, but it disappears rapidly as the electrons relax back into their original state.

This technique was applied to the atomically perfect LaSrCuO films synthesized at Brookhaven Lab. In films with a critical temperature of 26 degrees Kelvin (the threshold beyond which the superconductivity breaks down), the researchers discovered two new short-lived excitations -- both caused by fluctuating CDWs.

Gedik's technique even allowed the researchers to record the lifetime of CDW fluctuations -- just 2 picoseconds (a millionth of a millionth of a second) under the coldest conditions and becoming briefer as the temperatures rose. These waves then vanished entirely at about 100 Kelvin, actually surviving at much higher temperatures than superconductivity.

Ruling out a Suspect

The researchers then hunted for those same signatures in cuprate films with slightly different chemical compositions and a greater density of mobile electrons. The results were both unexpected and significant for the future of HTS research.

"Interestingly, the superconducting sample with the highest critical temperature, about 39 Kelvin, showed no CDW signatures at all," Gedik said.

The consistent emergence of CDWs would have bolstered the conjecture that they play an essential role in high-temperature superconductivity. Instead, the new technique's successful detection of such electron waves in one sample but not in another (with even higher critical temperature) indicates that another mechanism must be driving the emergence of HTS.

"Results like this bring us closer to understanding the mystery of HTS, considered by many to be one of the greatest problems in physics today," Bozovic said. "The source of this extraordinary phenomenon is slowly but surely running out of places to hide."

U.S. urges Syrian opposition to attend Rome talks

LONDON (Reuters) - A senior U.S. official on Sunday urged the Syrian opposition to attend a planned international meeting in Rome this week, saying it was a chance for rebels to make their case for more support.

The official, speaking on condition of anonymity, said there was dissension among the opposition about the utility of such meetings and some members have signaled they may not attend.

Nearly 70,000 people have been killed in Syria's civil war in the last 22 months since fighting broke out between rebels trying to oust Syrian President Bashar al-Assad and government forces and allied militias.

There appear to be growing tensions between the fighters on the ground and opposition members outside the country.

"The Syrian opposition leadership is under severe pressure now from its membership, from the Syrian people, to get more support from the international community and in that context there's quite a bit of internal discussion about the value of going to international conferences," the official told reporters travelling with U.S. Secretary of State John Kerry.

"The point that we're trying to make ... is that they have an opportunity in Rome with the meeting that the Italians have offered to host to see the very countries that have been their greatest supporters," the official said.

The Syrian National Coalition said on February 22 that it had turned down invitations to visit Washington and Moscow to protest what it described as international silence over the destruction of the historic city of Aleppo by government missile strikes.

On Saturday, the U.S. State Department issued a statement condemning a Syrian army Scud missile attack that killed dozens of people on Friday in Aleppo, and invited the opposition for talks on finding a negotiated settlement to the conflict.

CHANCE TO MEET KERRY

Invitations from Washington and Moscow had been extended to opposition coalition leader Mouz Alkhatib after he met the Russian and U.S. foreign ministers in Munich earlier this month.

Alkhatib, a cleric from Damascus who has said he is morally obliged to try to seek an exit for Assad without more bloodshed, has been criticized by others in the SNC for acting alone.

Thursday's planned meeting, which Kerry is expected to attend along with European, Arab and Turkish officials, is a chance for the opposition "to make their case for where they are in terms of the support we are giving them, what more they think they need and why," the senior U.S. official said.

The talks would also allow the opposition to meet Kerry, who took office on February 1 and is making his first trip as secretary of state to Europe and the Middle East.

"They are obviously going to have to make (their own) decision but we very much hope that we'll have an opportunity to hear from them and to work with them going forward," the official said.

The official said U.S. Ambassador to Syria Robert Ford, who was withdrawn from the country more than a year ago because of the violence, was travelling to Cairo on Sunday night to meet the opposition while the top U.S. diplomat for the Middle East, Beth Jones, would soon fly to Rome.

Kerry arrived in London on Sunday and is scheduled to travel to Berlin, Paris, Rome, Ankara, Cairo, Riyadh, Abu Dhabi and Doha before returning to Washington on March

Rocket attacks on an eastern districts of Aleppo, Syria's industrial and commercial hub, killed at least 29 people on Friday and trapped a family of 10 in the ruins of their home, opposition activists in the city said.

Armani, Dior rack up fashion wins at Oscars

Forget glamour girls Jessica Chastain versus Jennifer Lawrence. By the end of a long Oscars telecast, the only person who could have stolen the fashion conversation was first lady Michelle Obama ? and she did.

She presented the best picture award almost at the stroke of midnight Sunday via video stream in a silver Naeem Khan gown. It was the sort of Cinderella style moment that red-carpet watchers hunger for.

Until then, the most heated chatter about the Academy Awards likely was the boldface battle between Giorgio Armani and Dior Haute Couture.

Armani could claim some big wins: the designer dressed Chastain, Naomi Watts and Quvenzhane Wallis. Dior dressed Lawrence and Charlize Theron ? both are spokesmodels ? who hit it right in white.

Chastain, in a glistening copper-tone strapless gown with mermaid hem, looked like an old-world glamorous movie star, especially with her oversized vintage Harry Winston diamond earrings and bright red lipstick.

"I chose it because to me it was a throwback to old Hollywood," she said. "It's a very 'Happy birthday, Mr. President' dress."

Watts wore a gunmetal beaded gown with a geometric cutout on the bodice, also by Armani.

Quvenzhane (kwuh-VEHN'-juh-nay), with a silver headband in her hair and carrying a bedazzled puppy purse, wore an Armani Junior navy-blue dress with black, navy and silver jewels scattered on the skirt and a big bow on the back. She had another Armani dress, a pink one, ready for the afterparty. "I liked it because it was sparkly and puffy."

Lawrence was the belle of the ball in a white-and-pale pink strapless gown with fitted bustier and poufy hemline, sophisticated pulled-back hair, diamond-ball earrings and a delicate long necklace that hung down in back. The long train gave her trouble as she went to accept her award for best actress. She stumbled as she approached the stage to accept her Oscar.

Theron was sleek in an angular strapless dress with a fashion-right peplum and a buzz-cut hairdo.

Christos Garkinos, longtime red-carpet watcher and owner of Decades vintage store in Los Angeles, said, "You could have turned the TV off right when Charlize Theron came on. She was perfect."

The more interesting chatter, however, could be about the Jane Fondas and Sally Fields of the world. Fonda wore bright taxicab yellow Versace and Sally Field was in bright red.

"Women of a certain age almost gave the feeling that the older you get, the bolder you get," Garkinos said.

Hal Rubenstein, editor at large of InStyle magazine, was pretty impressed by 86-year-old Emmanuelle Riva in Lanvin. "Jane Fonda looks amazing because she's Jane Fonda, but Emmanuelle Riva was so elegant."

Another look that had people talking was Anne Hathaway's pale pink Prada dress. Rubenstein called the dress and Tiffany & Co. necklace "an Audrey Hepburn moment."

Garkinos wasn't as kind. Thanks to some awkwardly placed darts in the bust, he said it was more like Gwyneth Paltrow's big Academy Awards moment, when she wore a lovely Ralph Lauren pink dress but the fit wasn't quite right.

Hathaway, before the show, said her dress with a seemingly sweet vibe but with a strategically open back and sexy sides, was a last-minute choice. "It fit my mood and place where I'm at right now."

It almost seemed there were two routes to the red carpet, said Rubenstein: incredibly beaded and eye-catching, worn by Nicole Kidman in L'Wren Scott, Halle Berry in Versace, and Stacy Keibler in Naeem Khan; or a simple color with a great silhouette. He puts Lawrence, Reese Witherspoon in a strapless royal-blue Louis Vuitton gown with a black strip at the bustline and Jennifer Aniston in a Valentino red strapless gown in that camp.

"For some, there was a pull back to not do a lot, and that's where fashion is as well," Rubenstein said.

Amanda Seyfried's metallic halter dress by Alexander McQueen with a keyhole opening was three months in the making, and Berry said she trusted Donatella Versace to dress her like the Bond girl that she has been on the big screen. She ended up in a silver beaded-and-black gown with long sleeves and V-neck.

Jennifer Hudson's shiny, second-skin blue Roberto Cavalli almost looked like an animal print.

Kristen Stewart had an even paler blush gown; hers a hand-beaded strapless with tulle inserts by Reem Acra. She accentuated her gown with a 19th-century Fred Leighton necklace with 91 graduated diamonds.

Jennifer Garner chose a violet-colored Gucci with cascading ruffles in the back. Her 200-carat diamond-and-dark platinum necklace from the Neil Lane archives was a big statement.

Beaded gowns had a strong presence, worn by Sandra Bullock, in a fully embroidered Elie Saab; Renee Zellweger, in a sleek Carolina Herrera; and Adele in Jenny Packham. Catherine Zeta-Jones was statuesque in an all-gold Zuhair Muhad. Queen Latifah's white V-neck tank dress by Badgley Mischka had a lot of sparkle on the straps.

Salma Hayek's midnight-blue velvet Alexander McQueen gown had a gold embellished collar, and she carried a gold skull box clutch.

Helen Hunt wore a little bit of her conscience along with her blue column gown. It was from fast-fashion retailer H&M. She chose it because it was both accessible and because the company has launched a substantial green initiative. She did wear it, however, with hundreds of thousands of dollars of borrowed jewels.

For the men, the trend was beards, with George Clooney, Bradley Cooper, Ben Affleck and Tommy Lee Jones, among them.

(AP) ? Will Italy stay the course with painful economic reform? Or fall back into the old habit of profligacy and inertia? These are the stakes as Italy votes in a watershed parliamentary election Sunday and Monday that could shape the future of one of Europe's biggest economies.

Fellow EU countries and investors are watching closely, as the decisions that Italy makes over the next several months promise to have a profound impact on whether Europe can decisively put out the flames of its financial crisis. Greece's troubles in recent years were enough to spark a series of market panics. With an economy almost 10 times the size of Greece's, Italy is simply too big a country for Europe, and the world, to see fail.

Leading the electoral pack is Pier Luigi Bersani, a former communist who has shown a pragmatic streak in supporting tough economic reforms spearheaded by incumbent Mario Monti. On Bersani's heels is Silvio Berlusconi, the billionaire media mogul seeking an unlikely political comeback after being forced from the premiership by Italy's debt crisis. Monti, while widely credited with saving Italy from financial ruin, is trailing badly as he pays the price for the suffering caused by austerity measures.

Then there's the wild card: comic-turned-politician Beppe Grillo, whose protest movement against the entrenched political class has been drawing tens of thousands to rallies in piazzas across Italy. If his self-styled political "tsunami" sweeps into Parliament with a big chunk of seats, Italy could be in store for a prolonged period of political confusion that would spook the markets.

While a man of the left, Bersani has shown himself to have a surprising amount in common with the center-right Monti ? and the two have hinted at the possibility of teaming up in a coalition. Bersani was Monti's most loyal backer in Parliament during the respected economist's tenure at the head of a technocratic government. And in ministerial posts in previous center-left governments, Bersani fought hard to free up such areas of the economy as energy, insurance and banking services.

But it's uncertain that Monti will be able muster the votes needed to give Bersani's Democratic Party a stable majority in both houses of Parliament.

"Forming a government with a stable parliamentary alliance may prove tricky after elections," said Eoin Ryan, an analyst with IHS Global Insight. "A surge in support for anti-austerity parties is raising chances of an indecisive election result and post-vote political instability."

Another factor is turnout. Usually some 80 percent of the 50 million eligible voters go to the polls but experts are predicting many will stay away in anger, hurting mainstream parties.

When Berlusconi stepped down in November 2011, newspapers were writing his political obituary. At 76, blamed for mismanaging the economy and disgraced by criminal allegations of sex with an underage prostitute, the billionaire media baron appeared finished as a political force.

But Berlusconi has proven time and again ? over 20 years at the center of Italian politics ? that he should never be counted out.

The campaign strategy that has allowed him to become a contender in these elections is a simple one: please the masses by throwing around cash.

Berlusconi has promised to give back an unpopular property tax imposed by Monti as part of austerity measures. Even his purchase of start striker Mario Balotelli for his AC Milan soccer team was widely seen as a ploy to buy votes. Berlusconi has also appealed to Italy's right-wing by praising Italy's former fascist dictator Benito Mussolini during a ceremony commemorating Holocaust victims.

The most recent polls show Bersani in the lead with 33 percent of the vote, against 28 percent for Berlusconi's coalition with the populist Northern League. Grillo's 5 Star movement was in a surprise third place, with 17 percent support, while Monti's centrist coalition was notching 13 percent. The COESIS poll of 6,212 respondents had a margin of error of plus or minus 1.2 percent.

Pollster Renato Mannheimer said among his biggest clients heading into the elections were foreign banks seeking to gauge whether to hold or sell Italian bonds.

"They are worried mostly about the return of Berlusconi," Mannheimer said.

Uncertainty over the outcome of the vote has pushed the Milan stock exchange down in the days running up to the vote and bumped up borrowing costs, as investors express concern that Italy may back down from a reform course to pull the country out of recession.

Mannheimer said many undecided voters ? who comprise around one-third of the total electorate ? identify with the center-right, and that may help Berlusconi. He said that the undecided vote may also tilt heavily toward Grillo's protest movement.

The professorial Monti looked uncomfortable at first as a candidate but has recently warmed to the role. Like the others, he has not shied away from name calling, warning that Berlusconi is a "charlatan" and saying his return would be "horrific."

Bond analyst Nicholas Spiro said the election "will deliver the most important verdict on the eurozone's three-year-old austerity focused policies."

But he is betting on a period of political instability after the vote.

"An upset victory by Mr. Berlusconi may be markets' nightmare scenario," he said, "but the prospects for a stable and harmonious Bersani-Monti coalition government ? still the mostly likely outcome in our view ? are bleak."

London Fashion Week taken to capital's streets

London Fashion Week taken to capital's streets

By Amy De-Keyzer
February 22, 2013

AN EPSOM photographer took to the streets of the capital this week as London Fashion Week?stepped out among the black cabs and red buses.

Cassandra Mayers, a photographer and event organiser,?arranged a unique and eye-catching show as 11 models strutted their stuff along the tarmac streets and busy pavements, from Somerset House in The Strand to Freemasons' Hall in Great Queen Street, dressed in designer Carlotta Actis Barone's clothes.

Miss Mayers' vision was to push the boundaries of conventional catwalk shows and introduce fashion to a new audience.

She said: "My idea behind the show was to take fashion out of its controlled environment and make it a little more spontaneous and unpredictable.

"I wanted to show how fashion can be presented in a different way other than a straight clean catwalk.

"Also I feel fashion is something that the public don't often get to see.

"They all know London Fashion Week is happening but without a pass they only get to read about it afterwards and see it in photographs. I wanted to bring the fashion show to a different audience."

The experienced fashion and catwalk photographer, who?has previously held shoots amongst commuters?on the London Underground, said it was great to see all the shocked faces and people taking pictures on their mobile phones.

She now plans to hold more live street fashion events.

Models in the street show, held on Tuesday (February 19), wore bright and neon outfits with vibrant make-up, bringing a burst of colour to central London.

The world's top fashion designers and runway models descend on London each year for the renowned Fashion Week event which takes place for two weeks, in February and September.
