Cops bark like dogs, trick burglary suspects into surrendering

Some cops in Connecticut are more bark than bite. But their animal instincts were exactly what was called for in order to bring down a pair of suspected criminals.

WFSB reports on a pair of masked burglary suspects who had holed up inside a home in Connecticut and were refusing to cooperate with authorities. So, the cops decided the next logical move was issuing a threat to release dogs from their K-9 unit.

However, there was just one problem: None of the dogs were actually on the scene or available to be dispatched in the effort.

So, the New Have Police Department made due with their resources on hand; enlisting several of the dozen officers on site who barked like dogs in an effort to convince the two suspects that a pack of vicious dogs were chomping at the bit, just waiting to be unleashed.

And, in a surprising development, it actually worked. After the men heard the cops barking, they emerged from the home and surrendered to police.

Needless to say, McGruff the Crime Dog would be proud.

?These cops were trained to do stuff like that, right?? said an impressed sounding local resident, Gideon Gurley after witnessing the incident. "I guess that was the best technique to do what they needed to do to get people out."

The suspects, Kwame Wells-Jordan, 20, and Norman Boone, 23, have been charged with car theft and burglary with additional charges expected to be forthcoming.

UCLA hires Steve Alford as new basketball coach

LOS ANGELES (AP) ? UCLA hired Steve Alford as basketball coach on Saturday, luring him from New Mexico days after he signed a new 10-year deal with the Lobos.

Athletic director Dan Guerrero said Alford is "the perfect fit for UCLA" because he connects with a new generation of players and brings an up-tempo and team-oriented style of play to Westwood.

The 48-year-old coach succeeds Ben Howland, who was fired last weekend after 10 years and a 233-107 record that included three consecutive Final Four appearances and four Pac-12 titles. The Bruins were 25-10 this season, which ended with a 20-point loss to Minnesota in the second round of the NCAA tournament.

Alford led New Mexico to a 29-6 record this season that included the Mountain West regular-season and tournament titles. But the Lobos were upset by Harvard in the second round of the NCAAs shortly after Alford's new deal with the school had been announced.

Alford will be introduced at UCLA on Tuesday.

"I have been so fortunate and blessed in my life, and an opportunity to lead one of the greatest programs in college basketball history is once-in-a-lifetime," he said in a statement.

Alford had a 155-52 record in six years at New Mexico, with the Lobos making three trips to the NCAA tournament. He was selected Mountain West coach of the year three times.

His other head coaching stints were at Iowa (2000-07), Missouri State (1996-99) and Manchester College (1992-95) in his native Indiana.

Alford is a legend in the Hoosier state, where he starred at Indiana University from 1984-87 under coach Bob Knight. The Hoosiers won the national championship in his senior year. He also played on the gold medal-winning 1984 U.S. Olympic basketball team in Los Angeles as a college sophomore. Knight coached that team.

Alford was drafted by the Dallas Mavericks in 1987 and played four years in the NBA before starting his head coaching career at tiny Manchester.

Pope's foot-washing final blow for traditionalists

VATICAN CITY (AP) ? Pope Francis has won over many hearts and minds with his simple style and focus on serving the world's poorest, but he has devastated traditionalist Catholics who adored his predecessor, Benedict XVI, for restoring much of the traditional pomp to the papacy.

Francis' decision to disregard church law and wash the feet of two girls ? a Serbian Muslim and an Italian Catholic ? during a Holy Thursday ritual has become something of the final straw, evidence that Francis has little or no interest in one of the key priorities of Benedict's papacy: reviving the pre-Vatican II traditions of the Catholic Church.

One of the most-read traditionalist blogs, "Rorate Caeli," reacted to the foot-washing ceremony by declaring the death of Benedict's eight-year project to correct what he considered the botched interpretations of the Second Vatican Council's modernizing reforms.

"The official end of the reform of the reform ? by example," ''Rorate Caeli" lamented in its report on Francis' Holy Thursday ritual.

A like-minded commentator in Francis' native Argentina, Marcelo Gonzalez at International Catholic Panorama, reacted to Francis' election with this phrase: "The Horror." Gonzalez's beef? While serving as Cardinal Jorge Mario Bergoglio, Francis' efforts to revive the old Latin Mass so dear to Benedict and traditionalists were "non-existent."

The night he was chosen pope, March 13, Francis emerged from the loggia of St. Peter's Basilica without the ermine-rimmed red velvet cape, or mozzetta, used by popes past for official duties, wearing instead the simple white cassock of the papacy.

He also received the cardinals' pledges of obedience after his election not from a chair on a pedestal as popes normally do but rather standing, on their same level. In the days since, he has called for "intensified" dialogue with Islam ? a gesture that rankles some traditionalists because they view interfaith dialogue as a sign of religious relativism.

This year's Good Friday procession at Rome's Colosseum, which re-enacts Jesus Christ's crucifixion, was dedicated to the plight of Mideast Christians, with prayers calling for an end to "violent fundamentalism."

Francis, however, chose to stress Christians' positive relations with Muslims in brief remarks the end of the ceremony. He recalled Benedict's 2012 visit to Lebanon when "we saw the beauty and the strong bond of communion joining Christians together in that land and the friendship of our Muslim brothers and sisters and so many others."

Francis also raised traditional eyebrows when he refused the golden pectoral cross offered to him right after his election by Monsignor Guido Marini, the Vatican's liturgy guru who under Benedict became the symbol of Benedict's effort to restore the Gregorian chant and heavy silk brocaded vestments of the pre-Vatican II liturgy to papal Masses.

Marini has gamely stayed by Francis' side as the new pope puts his own stamp on Vatican Masses with no-nonsense vestments and easy off-the-cuff homilies. But there is widespread expectation that Francis will soon name a new master of liturgical ceremonies more in line with his priorities of bringing the church and its message of love and service to ordinary people without the "high church" trappings of his predecessor.

There were certainly none of those trappings on display Thursday at the Casal del Marmo juvenile detention facility in Rome, where the 76-year-old Francis got down on his knees and to wash the feet of 12 inmates, two of them women. The rite re-enacts Jesus' washing of the feet of his 12 apostles during the Last Supper before his crucifixion, a sign of his love and service to them.

The church's liturgical law holds that only men can participate in the rite, given that Jesus' apostles were all male. Priests and bishops have routinely petitioned for exemptions to include women, but the law is clear.

Francis, however, is the church's chief lawmaker, so in theory he can do whatever he wants.

"The pope does not need anybody's permission to make exceptions to how ecclesiastical law relates to him," noted conservative columnist Jimmy Akin in the National Catholic Register. But Akin echoed concerns raised by canon lawyer Edward Peters, an adviser to the Vatican's high court, that Francis was setting a "questionable example" by simply ignoring the church's own rules.

"People naturally imitate their leader. That's the whole point behind Jesus washing the disciples' feet. He was explicitly and intentionally setting an example for them," he said. "Pope Francis knows that he is setting an example."

The inclusion of women in the rite is problematic for some because it could be seen as an opening of sorts to women's ordination. The Catholic Church restricts the priesthood to men, arguing that Jesus and his 12 apostles were male.

Francis is clearly opposed to women's ordination. But by washing the feet of women, he jolted traditionalists who for years have been unbending in insisting that the ritual is for men only and proudly holding up as evidence documentation from the Vatican's liturgy office saying so.

"If someone is washing the feet of any females ... he is in violation of the Holy Thursday rubrics," Peters wrote in a 2006 article that he reposted earlier this month on his blog.

In the face of the pope doing that very thing, Peters ? like many conservative and traditionalist commentators ? have found themselves trying to put the best face on a situation they don't like lest they be openly voicing dissent with the pope.

By Thursday evening, Peters was saying that Francis had merely "disregarded" the law ? not violated it.

The Rev. John Zuhlsdorf, a traditionalist blogger who has never shied from picking fights with priests, bishops or cardinals when it concerns liturgical abuses, had to measure his comments when the purported abuser was the pope himself.

"Before liberals and traditionalists both have a spittle-flecked nutty, each for their own reasons, try to figure out what he is trying to do," Zuhlsdorf wrote.

But, in characteristic form, he added: "What liberals forget in their present crowing is that even as Francis makes himself ? and the church ? more popular by projecting (a) compassionate image, he will simultaneously make it harder for them to criticize him when he reaffirms the doctrinal points they want him to overturn."

One of the key barometers of how traditionalists view Francis concerns his take on the pre-Vatican II Latin Mass. The Second Vatican Council, the 1962-65 meetings that brought the church into the modern world, allowed the celebration of the Mass in the vernacular rather than Latin. In the decades that followed, the so-called Tridentine Rite fell out of use almost entirely.

Traditionalist Catholics who were attached to the old rite blame many of the ills afflicting the Catholic Church today ? a drop in priestly vocations, empty pews in Europe and beyond ? on the liturgical abuses that they say have proliferated with the celebration of the new form of Mass.

In a bid to reach out to them, Benedict in 2007 relaxed restrictions on celebrating the old Latin Mass. The move was aimed also at reconciling with a group of schismatic traditionalists, the Society of St. Pius X, who split from Rome precisely over the Vatican II reforms, in particular its call for Mass in the vernacular and outreach to other religions, especially Judaism and Islam.

Benedict took extraordinary measures to bring the society back under Rome's wing during his pontificate, but negotiations stalled.

The society has understandably reacted coolly to Francis' election, reminding the pope that his namesake, St. Francis of Assisi, was told by Christ to go and "rebuild my church." For the society, that means rebuilding it in a pre-Vatican II vision.

The head of the society for South America, the Rev. Christian Bouchacourt, was less than generous in his assessment of Francis.

"He cultivates a militant humility, but can prove humiliating for the church," Bouchacourt said in a recent article, criticizing the "dilapidated" state of the clergy in Buenos Aires and the "disaster" of its seminary. "With him, we risk to see once again the masses of Paul VI's pontificate, a far cry from Benedict XVI's efforts to restore to their honor the worthy liturgical ceremonies."

FBI UFO memo is bureau's most viewed public record

FBI UFO memo: The Federal Bureau of Investigation says that its Hottel memo, which reports on an alleged flying saucer sighting, has been viewed nearly a million times since 2011.

By Megan Gannon,?LiveScience.com / March 27, 2013

A single-page March 22, 1950, memo by Guy Hottel, special agent in charge of the Washington Field Office, regarding UFOs is the most viewed document in the FBI Vault, an online repository of public records.

The FBI says its most viewed public record is a memo from 1950 recounting a strange story someone told an agent about three "flying saucers" that were allegedly recovered in New Mexico.

The so-called?Hottel memo?was first released in the late 1970s under the Freedom of Information Act, but it's been viewed nearly a million times since 2011, when the FBI launched an online database of public records called the Vault.

Dated March 22, 1950, the memo was addressed to FBI Director J. Edgar Hoover and written by Guy Hottel, then head of the Bureau's field office in Washington, D.C. Hottel was reporting what an Air Force investigator said that someone else told him about the crashed saucers.

The following details of the report have perhaps fueled the hopes of those who want to believe: "They [the saucers] were described as being circular in shape with raised centers, approximately 50 feet in diameter. Each one was occupied by three bodies of human shape but only three feet tall, dressed in metallic cloth of a very fine texture. Each body was bandaged in a manner similar to the blackout suits used by speed fliers and test pilots."

For the record, FBI officials said in a statement on Monday (March 25) that the Hottel memo "does not prove the?existence of UFOs; it is simply a second- or third-hand claim that we never investigated."

Bureau officials also say there is no reason to believe that the story has anything to do with the infamous?1947 Roswell crash?in New Mexico.?Hoover did actually order his agents?to verify any?UFO sightings?after the?Roswell incident and until?July 1950. That?the Hottel report was never investigated suggests "our Washington Field Office didn't think enough of that flying saucer story to look into it," the FBI statement says.

Sharapova reaches Key Biscayne final for 5th time

KEY BISCAYNE, Fla. (AP) ? Maria Sharapova swept the first 10 points Thursday, then hardly let up from there. If she can keep it going for one more round, she'll finally have that elusive Sony Open title.

The four-time runner-up advanced to another Key Biscayne final by beating Jelena Jankovic 6-2, 6-1.

With a victory Saturday, the No. 3-seeded Sharapova would plug one of the few holes in her resume. She completed a career Grand Slam by winning the French Open last year but has never won the tournament near downtown Miami.

"It would mean so much to me," the Russian said. "I absolutely love this city. It's the first city I landed in when I came to the United States as a little girl."

Sharapova will face the winner of Thursday night's match between five-time champion Serena Williams and defending champ Agnieszka Radwanska.

Andy Murray, the 2009 champion and runner-up last year, advanced to the semifinals by beating No. 9 Marin Cilic 6-4, 6-3. Murray's opponent Friday night will be the winner of the match Thursday night between No. 4 Tomas Berdych and No. 8 Richard Gasquet.

No. 3 David Ferrer will play 34-year-old Tommy Haas in the other semifinal.

On a sunny, mild afternoon, Sharapova won seven consecutive games during one stretch against the No. 22-seeded Jankovic. Sharapova committed only 10 unforced errors from the baseline in 88 points while breaking serve six times.

Sharapova took the Indian Wells title two weeks ago and has won 22 consecutive sets, a career best, while winning 11 matches in a row. But she endured a sloppy quarterfinal against Sara Errani, winning despite 57 unforced errors, including 13 double-faults.

She double-faulted only three times against Jankovic and won 23 of 25 points on her first serve.

"I just really thought I needed to step it up from my last match and play a little better," she said. "I was really happy with the way I focused."

Jankovic, playing for the second time in less than 18 hours, was repeatedly a step late trying to reach Sharapova's shots.

"I wasn't moving," she said. "I felt heavy on the court. I felt really tired and exhausted."

Jankovic questioned scheduling that forced her to play in consecutive sessions while Williams and Radwanska had a day off before the semifinals.

"Kind of crazy," she said. "I had a couple of hours of sleep, and then I had to be back on the court."

Sharapova looked fresh even though she has played a lot of tennis lately. She's bidding to become the third woman to win Indian Wells and Key Biscayne in the same year.

Steffi Graf did it in 1994 and 1996, and Kim Clijsters won both in 2005.

"Winning a title on its own, whether it's here or Indian Wells, is a great achievement," Sharapova said. "To be able to come back from that and recover in just a few days and come back to the final here, it's great. Physically, many years ago I wouldn't be able to do that, so I'm very proud of the way I have recovered."

Sharapova has lost the Key Biscayne final to four different players ? Clijsters in 2005, Svetlana Kuznetsova in '06, Victoria Azarenka in '11 and Radwanska last year.

This is the Modem World: Nerds in rabbit holes

Each week Joshua Fruhlinger contributes This is the Modem World, a column dedicated to exploring the culture of consumer technology.

DNP This is the Modem World Nerds in Rabbit Holes

I have many interests: mountain biking, martial arts, video games, running, reading, cooking and horror movies. For each one of these, there is an internet rabbit hole so deep, so full of information and compatriots that it's a miracle I ever actually follow through on them. Ask yourself this: Do you do what you say you do online?

The internet is great at allowing people to nerd out on their particular interests. While it serves up news and media like a champ, many of us spend our time deep-diving into whatever rabbit hole interests us. When we nerd out about technology here at Engadget, for instance, we're getting a double dose: reading about technology in a tech environment. It's a beautiful thing; it's addictive and we lose sight of reality while we're going deep. We could be in a bar, at home, at the office -- wherever it is, we lose sense of our environment.

Court approves American Airlines-US Airways merger

A judge on Wednesday approved AMR Corp's plan to merge with US Airways Group , a step toward creating the world's largest airline.

AMR, parent of American Airlines and in bankruptcy since November 2011, must still construct a formal restructuring plan incorporating the merger that meets court and creditor approval before the airline can emerge from bankruptcy.

American Airlines announced the plan to combine with US Airways last month, a deal that also requires regulatory approval.

In a crowded Manhattan courtroom on Wednesday, U.S. Bankruptcy Judge Sean Lane declined to approve, for now, a planned $19.9 million severance package for Tom Horton, AMR's outgoing chief executive.

Lane said he was uncertain as to whether the severance package requires his approval at all, or whether the matter is more appropriate for inclusion in AMR's formal restructuring plan.

That plan, which all debtors in bankruptcy must propose, will lay out how creditors will get paid back, and will require creditor approval.

The fate of the severance payment is unclear. The version of the merger agreement that earned the judge's approval may have to be amended to remove it.

Jack Butler, a lawyer for AMR's creditors' committee, said it was too early to tell how the parties will deal with the severance issue.

"The companies said they were prepared to amend the merger agreement in any respect, and I expect that there will be an amendment," Butler said after the hearing.

AMR filed for bankruptcy citing untenable labor costs after years of futile attempts to negotiate cost savings from its unionized workforce. It had been the last major U.S. carrier to go through bankruptcy, after its competitors underwent the same process in the last decade.

Wednesday's approval was a key moment in AMR's 16-month odyssey through reorganization under Chapter 11 of the bankruptcy code. Stephen Karotkin, a lawyer for AMR, called Wednesday's hearing a "watershed event" that moves AMR a step closer to exiting bankruptcy.

The airline began its bankruptcy process flatly opposed to merging while still in bankruptcy, but eventually relented to pressure from its creditors' committee, represented by Butler and Jay Goffman, both lawyers at Skadden Arps Slate Meagher & Flom.

US Airways Chief Executive Doug Parker wooed AMR aggressively, taking advantage of AMR's labor relations problems to appeal to its unions.

US Airways hammered out a tentative deal with the unions last April, before formal merger talks between the two companies' management teams had gone into full swing.

The creditors' committee eventually convinced AMR to adopt a protocol to evaluate a merger, and played a large role in analyzing the net savings and benefits from a merger.

AMR's current shareholders are expected to receive a 3.5 percent equity stake in the new firm, which would make it one of the few major bankruptcies in which equity holders earn some recovery.

The Skadden legal team advising the creditors' committee also played a central part in negotiating the new management structure, including the details of Horton's severance package.

Parker will serve as CEO of the combined carrier, while Horton, who became AMR's CEO when it filed for bankruptcy, will serve as chairman of the airline through the first annual meeting of shareholders. After that Parker will take on the chairman role.

The merger is expected to close in the third quarter.

The case is In re AMR Corp et al, U.S. Bankruptcy Court, Southern District of New York, No. 11-15463.

Better-educated parents feed children fewer fats and less sugar

Mar. 27, 2013 ? The level of education of parents has an influence on the frequency with which their children eat foods linked to obesity. The children of parents with low and medium levels of education eat fewer vegetables and fruit and more processed products and sweet drinks.

An international group of experts from eight European countries have analysed the relation between parents' levels of education and the frequency with which their children eat food linked to overweight.

The Identification and prevention of dietary- and lifestyle-induced health effects in children and infants (IDEFICS) study includes data from 14,426 children aged between two and nine from eight European countries: Italy, Estonia, Cyprus, Belgium, Sweden, Hungary, Germany and Spain.

The results published in the journal Public Health Nutrition confirm that parents with a lower level of education feed their children food rich in sugars and fats more often than those parents with a higher level of education, who feed their children more products of a higher nutritional quality, including vegetables, fruit, pasta, rice and wholemeal bread.

"The greatest differences among families with different levels of education are observed in the consumption of fruit, vegetables and sweet drinks," explains Juan Miguel Fern?ndez Alvira, the author of the work and researcher from the University of Zaragoza to SINC.

For the authors, this implies a greater risk of developing overweight and obesity in children from less advantaged socio-cultural groups. "The programmes for the prevention of childhood obesity through the promotion of healthy eating habits should specifically tackle less advantaged social and economic groups, in order to minimise inequalities in health," concludes Fern?ndez Alvira.

Childhood nutrition

Childhood, from two to fourteen years old, is a growth period during which the requirements for energy and nutrients increase. Nevertheless, the World Health Organisation warns of the importance of monitoring the diet of the youngest members of society, as almost 40 million children under the age of five suffered from overweight in 2010.

In fact, recommendations for children over two do not differ greatly from those for adults. Their diet should include cereals, fruit, vegetables, dairy products, lean meats, fish, poultry, eggs and nuts.

Dieticians and nutritionists recommend that parents offer children a wide variety of foods and avoid using food as a method to award or punish behaviour. Experts believe that this age group can decide how much to eat, provided the food is always healthy and nutritious.

The Weinstein Company buys Nicole Kidman as Grace Kelly

By Lucas Shaw

NEW YORK (TheWrap.com) - The Weinstein Company has acquired domestic distribution rights to "Grace of Monaco," an upcoming biopic starring Nicole Kidman as Hollywood star-turned-princess Grace Kelly, the independent distributor announced on Monday.

Weinstein will release the film December 27 in limited markets, just in time for it to qualify for the 2014 Academy Awards.

Arash Amel wrote the script for the film, which focuses on Kelly's marriage to Prince Rainier III of Monaco (played by Tim Roth) and a dispute between the prince and French leader Charles De Gaulle.

Kelly appeared in 11 films before that marriage, including "High Society," "To Catch a Thief" and Alfred Hitchock's "Rear Window" and "Dial M for Murder."

Olivier Dahan directed the biopic, which also features Frank Langella, Parker Posey and Paz Vega. Amel, Uday Chopra and Pierre-Ange Le Pogram produced the film, which TWC executives saw earlier this month in London.

"More than 30 years after her death, Grace Kelly's story continues to be one of insurmountable allure, and we are so happy Olivier Dahan has brought it new life," TWC Co-Chairman Harvey Weinstein said in a statement. "As always, Nicole Kidman's commanding performance is the perfect portrait of a woman who was not only royalty but who also remains a legend of the silver screen and fashion icon."

TWC's David Glasser and Mical Steinberg made the deal with CAA and Le Pogam.

"It has been a wonderful experience to be working with Nicole, Tim, Frank and the whole group," Dahan said in a statement. "I am very happy now to share the experience with Monsieur Weinstein and the whole team at TWC."

Prince Harry to tour Hurricane Sandy damage in US visit

Chris Jackson / Getty Images

By Eun Kyung Kim, TODAY contributor

Prince Harry plans to visit the United States on an official multi-stop journey that will include a visit to wounded veterans.

The prince will be in America from May 9-15, the palace said in a briefing Monday. His trip will include a stop in Washington, D.C., where he will visit the Walter Reed National Military Medical Center, a facility for wounded service members.

Harry, an officer in the British Army, recently returned from a second tour of duty in Afghanistan.

The prince also plans to visit a Capitol Hill exhibit on landmine clearance, a campaign passionately taken up by his mother, Princess Diana.

Harry also will tour areas hit by Hurricane Sandy in New York and New Jersey, along with a visit to Greenwich, Conn., to attend a polo match. Denver also will be on his tour stop.

The May trip will be an official visit on behalf of England, unlike the last time the prince visited the United States in August 2012 following the Summer Olympics. He spent several days in Las Vegas, where he was famously photographed nude by friends he met at the time. Harry later said he showed poor judgment, and that ?I let my family down; I let other people down? with the incident.

Significant insights into common form of autism: Study identifies genetic connections in 15q duplication syndrome

Mar. 26, 2013 ? A new study published in the March issue of Autism Research from the University of Tennessee Health Science Center and Le Bonheur researchers is making the genetic connections between autism and Chromosome 15q Duplication Syndrome (Dup15q).

The Memphis researchers determined that the maternally derived or inherited duplication of the region inclusive of the UBE3A gene (also known as the Angelman/Prader-Willi syndrome locus) are sufficient to produce a phenotype on the autism spectrum in all ten maternal duplication subjects. The number of subjects was too small to determine if parental duplications do not cause autism. The team assembled the largest single cohort of interstitial 15q duplication subjects for phenotype/genotype analysis of the autism component of the syndrome.

Chromosome 15q Duplication Syndrome (Dup15q) results from duplications of chromosome 15q11-q13. Duplications that are maternal in origin often result in developmental problems. The larger 15q duplication syndrome, which includes individuals with idic15, manifests itself in a wide range of developmental disabilities including autism spectrum disorders; motor, cognitive and speech/language delays; and seizure disorders among others. While there is no specific treatment plan, therapies are available to address or manage symptoms.

Previous research suggests that as many as 1,000 genes may contribute to autism phenotypes, but as much as 1-3 percent of all autism spectrum disorder cases may be a result of 15q11-q13 duplication alone.

The researchers also found through EEG evaluations a pattern that looks like the type of signal you see when individuals take GABA promoting drugs (benzodiazepines). The lead researcher on this study, Lawrence T. Reiter, PhD, says this signal gives clinicians a clue about what types of anti-seizure medication may be most useful in children with 15q duplications.

Reiter says genetic testing can help families connect to resources, like the Dup15q Alliance. Reiter is an associate professor in Department of Neurology with an adjunct appointment in Pediatrics at UTHSC.

"If a pediatrician suspects autism due to hypotonia and developmental delay, I highly recommend they order an arrayCGH test. Duplication 15q is the second most common duplication in autism. The test will help families in future treatments specific to this sub-type of autism," he said.

Reiter collaborated with UTHSC and Le Bonheur Neurologist Kathryn McVicar, MD, and Geneticist Eniko K. Pivnick, MD. The study was funded by the Herbert and Mary Shainberg Neuroscience Fund. Reiter serves on the scientific advisory board for the Duplication 15q Alliance and Idic15 Canada.

Playboy magazine founder Hugh Hefner and Crystal Harris, his new wife.

By Allison Takeda, Us Weekly

Everyone comes with baggage from past relationships, but Hugh Hefner's romantic history is a little -- OK, a lot -- more crowded than others'. In a new interview with Esquire magazine, the 86-year-old Playboy founder confesses to sleeping with many, many women over the years. Too many to count, in fact.

PHOTOS: Hugh Hefner's girlfriends

"How could I possibly know? Over a thousand, I'm sure," the mogul says of the number of ladies he's taken to bed. "There were chunks of my life when I was married, and when I was married I never cheated. But I made up for it when I wasn't married. You have to keep your hand in."

Hefner's hand is out of the game now, thanks to the magazine publisher's relationship with wife Crystal Harris. Speaking about his 26-year-old bride, whom he wed in December, the multi-millionaire gushes that he's a happy, committed, one-woman man.

"All our friends think it's made in heaven," he tells Esquire of his third marriage. (Hef was wed twice before, to Mildred Williams from 1949 to 1959, and to Kimberley Conrad from 1989 to 2010.) "It's only people who don't know us, who simply see us as stereotypes in terms of age and beauty."

"I just feel very, very fortunate to have found her at this stage in my life. I saved the best till last," he says of the model.

Later, musing about his plans for the future, he adds: "I want the rest of my life to be very much like it is now. I want it to be like this."

Egypt's president hints on Twitter of taking defensive action

CAIRO (AP) ? Egypt's president warns he may be about to take measures he did not specify to "protect this nation."

Mohammed Morsi's warning came in a series of tweets posted on Sunday, two days after violent clashes between supporters of his Muslim Brotherhood and opposition protesters in Cairo. At least 200 people have been injured, some seriously, outside the Cairo headquarters of the Brotherhood, Egypt's most dominant political group.

An Islamist elected in June, Morsi also warned that "appropriate measures" would be taken against politicians found to be behind Friday's violence, regardless of their seniority. Anyone found to be using the media to "incite violence" will also be held accountable, he added.

Friday's clashes followed an assault a week earlier by Brotherhood supporters on protesters painting hostile graffiti outside the group's headquarters.

Hawaii Wedding Photographers

Obviously not all couples are the same which works well for the Hawaii wedding packages market. Many services allow for customization based on the client's needs since all are different and people desire ceremonies that cater to their own ideals. The extravagance of a ceremony is really based on not only the customer's wants, but also their budget. For those interested in the idea yet not certain as to what might be affordable, the internet can be a useful tool. There are a plethora of Hawaii wedding packages websites which offer advice and prices on everything from flowers to location. Some packages even include suggestions on accommodations for the wedding party, families and guests, and in many cases the accommodations are included in the overall cost of the package.

Research is key for couples who want to find the package that is right for them. Hawaiian ceremonial services know that there are clients who want everything which is why there are packages that provide onsite coordinators, flowers, minister, solo musicians, a professional Hawaiian wedding photographer, limo, cake, chairs and an arbor for the beach, and more. For those willing to spend a little extra, the can receive a reception, complete photography session while touring an island, massage, hair and makeup for bride, a wedding certificate, the list goes on offering weddings as diverse as the couples.

The average price for all inclusive services can run upwards of four thousand dollars. There are companies that take into consideration that some clients will desire more finery, while others want more of the basics. For that reason many services usually include at least two different packages for clients to choose from. For example, one option allows for the clients to stay a resort style condominium, and another offer a resort grade hotel. Options such as these help the clients to feel more relaxed as the duration of the stay is similar to that of a Hawaiian vacation. Prices that include accommodations such as these often incorporate an entire package and can range anywhere from one hundred twenty a night to over four thousand.

The most popular locations for the exchanging of vows in the Hawaiian Islands are Maui, Oahu, and Kauai, with Maui being the most sought after. The Hawaiian Islands are so appealing because of the tropical setting and gorgeous landscapes. The Island's histories are steeped in myths and legends which provide an essence of mystery and romance. The Island's mysticism attracts many people, especially those who are seeking a beautiful location for starting their lives together. Included among the diverse Hawaii wedding packages some can be found that advertises by way of encouraging customers to incorporate the spirit of Hawaii into the ceremony, one that honors the island's heritage, traditions, and myths. Ceremonies such as these have taken into consideration that not everyone desires all the bells and whistles and would rather incorporate more if the Island's natural beauty. For couples who want an exotic setting yet not a lot of flare, packages can be found which provide low-key and informal ceremonies that include wedding services or simply just vow renewal. Companies such as these provide the necessities, such as the minister and a small set up on a beach. For a little extra cost clients can choose to have photos taken and leis for the bride and groom.

Most packages include Hawaii wedding photographers for recording the entirety of the service, or simply for capturing those special moments. A fact couples should keep in mind when planning a tropical ceremony is that top wedding photographers can be booked up to a year in advance, so planning ahead is important. Wedding photography began as an art form in the 1820's. People did not commonly pose for pictures during the ceremony or for documenting the service at all until the late nineteenth century. This was mainly due to the photographer's large and rather cumbrous equipment. Traditionally, recording the entirety of the event did not come into vogue until the advent of more streamlined camera equipment in the 1970's. This paved the way for the wedding photographers in places such as Hawaii by allowing for more ease of transporting equipment on beaches.

Two different types of photography are popular for ceremonies which are traditional and photo journalistic. Traditional are more classic in nature and focus on capturing the overall scenes of the ceremony, while photo journalistic tend to focus more on capturing emotions and telling a story. Hawaii wedding photographers are very popular among people that flock to the islands. When choosing a photographer, potential clients can choose to look through portfolios to find a look that is right for them. Many can be found through the internet and allow clients to peruse portfolios with ease and get a taste for all the beautiful landscapes and settings of the islands for truly, "The heavens declare the glory of God; and the firmament sheweth his handywork" (Psalm 19:1). While gaining a sense of the memories of the ceremony, Hawaii wedding photographers can help to preserve those special moments in breathtaking ways.

Researchers use metamaterials to observe giant photonic spin hall effect

Friday, March 22, 2013

Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials ? artificial nanoconstructs whose optical properties arise from their physical structure rather than their chemical composition. Engineering a unique two-dimensional sheet of gold nanoantennas, the researchers were able to obtain the strongest signal yet of the photonic spin Hall effect, an optical phenomenon of quantum mechanics that could play a prominent role in the future of computing.

"With metamaterial, we were able to greatly enhance a naturally weak effect to the point where it was directly observable with simple detection techniques," said Xiang Zhang, a faculty scientist with Berkeley Lab's Materials Sciences Division who led this research. "We also demonstrated that metamaterials not only allow us to control the propagation of light but also allos control of circular polarization. This could have profound consequences for information encoding and processing."

Zhang is the corresponding author of a paper describing this work in the journal Science. The paper is titled "Photonic Spin Hall Effect at Metasurfaces." Co-authors are Xiaobo Yin, Ziliang Ye, Jun Sun Rho and Yuan Wang.

The spin Hall effect, named in honor of physicist Edwin Hall, describes the curved path that spinning electrons follow as they move through a semiconductor. The curved movement arises from the interaction between the physical motion of the electron and its spin ? a quantized angular momentum that gives rise to magnetic moment. Think of a baseball pitcher putting spin on a ball to make it curve to the left or right.

"Light moving through a metal also displays the spin Hall effect but the photonic spin Hall effect is very weak because the spin angular momentum of photons and spin-orbit interactions are very small," says Xiaobo Yin, a member of Zhang's research group and the lead author of the Science paper. "In the past, people have managed to observe the photonic spin Hall effect by generating the process over and over again to obtain an accumulative signal, or by using highly sophisticated quantum measurements. Our metamaterial makes the photonic spin Hall effect observable even with a simple camera."

Metamaterials have garnered a lot of attention in recent years because their unique structure affords electromagnetic properties unattainable in nature. For example, a metamaterial can have a negative index of refraction, the ability to bend light backwards, unlike all materials found in nature, which bend light forward. Zhang, who holds the Ernest S. Kuh Endowed Chair Professor of Mechanical Engineering at the University of California (UC) Berkeley, where he also directs the National Science Foundation's Nano-scale Science and Engineering Center, has been at the forefront of metamaterials research. For this study, he and his group fashioned metamaterial surfaces about 30 nanometers thick (a human hair by comparison is between 50,000 and 100,000 nanometers thick). These metasurfaces were constructed from V-shaped gold nanoantennas whose geometry could be configured by adjusting the length and orientation of the arms of the Vs.

"We chose eight different antenna configurations with optimized geometry parameters to generate a linear phase gradient along the x direction," says Yin. "This enabled us to control the the propagation of the light and introduce strong photon spin-orbit interactions through rapid changes in direction. The photonic spin Hall effect depends on the curvature of the light's trajectory, so the sharper the change in propagation direction, the stronger the effect."

Since the entire metasurface sample measured only 0.3 millimeters, a 50-millimeter lens was used to project the transmission of the light through the metamaterial onto a charge-coupled device (CCD) camera for imaging. From the CCD images, the researchers determined that both the control of light propagation and the giant photonic spin Hall effect were the direct results of the designed meta-material. This finding opens up a wealth of possibilities for new technologies.

"The controllable spin-orbit interaction and momentum transfer between spin and orbital angular momentum allows us to manipulate the information encoded on the polarization of light, much like the 0 and 1 of today's electronic devices," Yin says. "But photonic devices could encode more information and provide greater information security than conventional electronic devices."

Yin says the ability to control left and right circular polarization of light in metamaterial surfaces should allow for the formation of optical elements, like highly coveted "flat lenses," or the management of light polarization without using wave plates.

"Metamaterials provide us with tremendous design freedom that will allow us to modulate the strength of the photonic spin Hall effect at different spatial locations," Yin says. "We knew the photonic spin Hall effect existed in nature but it was so hard to detect. Now, with the right metamaterials we can not only enhance this effect we can harness it for our own purposes."
