Genetic risk for obesity found in many Mexican young adults

May 21, 2013 ? As many as 35 percent of Mexican young adults may have a genetic predisposition for obesity, said a University of Illinois scientist who conducted a study at the Universidad Aut?noma de San Luis Potos?.

"The students who inherited genetic risk factors from both parents were already 15? pounds heavier and 2 inches bigger around the waist than those who hadn't. They also had slightly higher fasting glucose levels," said Margarita Teran-Garcia, a U of I professor of food science and human nutrition.

In the study, 251 18- to 25-year-olds were tested for risk alleles on the FTO gene as part of the Up Amigos project, a collaboration of scientists at the U of I and the Mexican university. The researchers are following the 10,000 yearly applicants to the Universidad Aut?noma de San Luis Potos? to learn how changes in students' weight, body mass index (BMI), and eating and exercise habits affect their health over time.

According to Teran-Garcia, the FTO gene is associated with a predisposition to obesity, increased BMI, and increased waist circumference. These traits can in turn contribute to many health-related problems, including cardiovascular disease and diabetes.

Of the young adults tested in the study, 15 percent had inherited the genetic risk from both parents -- in other words, they carried two copies of the risk allele. Another 20 percent had inherited risk from one parent, meaning they had one copy of the risk allele. Sixty-five percent of the students in the study did not carry the risk allele.

"If young people realize early that they have this predisposition, they can fight against it. If they are at risk for obesity, eating a healthy diet and getting regular exercise is even more important for them," Teran-Garcia said.

She noted that 85 percent of Hispanics in the United States are of Mexican origin.

Although FTO markers and analysis are available for large groups of Caucasians, Asians, and African-Americans, few studies have examined the effects of this gene in Mexican and Mexican- American populations.

"This is the first study to target young adults in Mexico, although one other study has followed older Mexican adults who had already been diagnosed with diabetes, obesity, and obesity-related diseases," she said.

Scientists hypothesize that "fat" genes may be influenced by epigenetic modifications, she said. "So even if you have this predisposition, you may be able to change the way those genes behave by eating the right foods and getting more exercise. These good habits are especially important for young people who have a genetic risk for obesity."

"FTO genotype is associated with body mass index and waist circumference in Mexican young adults" is available online in the Open Journal of Genetics (2013, 3, 44-48). Co-authors are Teran-Garcia, Itzel Vazquez-Vidal, and Michelle Mosley, of the U of I Department of Food Science and Human Nutrition, Flavia C.D. Andrade of the U of I Department of Kinesiology and Community Health, and Eduardo Medina-Cerda and Celia Aradillas-Garcia of the Universidad Auton?ma de San Luis Potos? in Mexico.

Nintendo partners with Best Buy so you can play unreleased Wii U games in store during E3

There's nothing more frustrating than watching a product or service get announced, then having to wait an age to try it out. Nintendo hears that, and has announced via Nintendo Direct, that during E3 week, Best Buy will have playable demos of as-yet released Wii U games in 100 stores across the US and Canada. Given that no one was likely expecting any new hardware from the firm, it's clear the gaming stalwart is looking for other ways to stir-up some interest. There's no mention of titles, so we're left to assume they'd be the games announced at the show. Either way, scratch out that week in June to make sure you find out first hand. Scrub right to the end of the video past the break to see the announcement for yourself.

FBI searches apartment in ricin letter case

SPOKANE, Wash. (AP) ? Authorities in hazardous materials suits searched a downtown Spokane apartment Saturday, investigating the recent discovery of a pair of letters containing the deadly poison ricin.

Few details have been released in the case, and no arrests have been made. Federal investigators have been searching for the person who sent the letters, which were postmarked Tuesday in Spokane.

The letters were addressed to the downtown post office and the adjacent federal building, but authorities have not released a potential motive. They also have not said whether the letters targeted anyone in particular.

Ricin is a highly toxic substance made from castor beans. As little as 500 micrograms, the size of the head of a pin, can kill an adult if inhaled or ingested.

There have been no reports of illness connected to the letters.

FBI agents, Spokane police and U.S. Postal Service inspectors descended on the three-story apartment building Saturday morning and the investigation continued into the afternoon.

FBI spokeswoman Ayn Sandalo Dietrich would not say whether agents were questioning anyone in connection with the case.

"We are not actively looking for a subject," Sandalo Dietrich said. "We are not asking the public's help in bringing someone in."

Despite the hazmat suits, officials said apartment residents were not at risk, and people were seen coming in and out of the brick building in the city's historic Browne's Addition neighborhood.

"There's no public risk," Sandalo Dietrich said.

Scott Ward has lived in the building for three years, and lives on the second floor near the apartment that was being searched. He said he does not know the neighbor who lives in that apartment.

"He's a guy with a big beard," Ward said. "He sticks to himself."

"He doesn't talk," said Ward, who added he was awakened about 7 a.m. by the sounds of "banging and what sounded like a big vacuum."

Building resident Jim Lehman said he was asleep when he was called by a friend. "He said, 'hey Jim, you're surrounded,'" Lehman said. Lehman said he saw workers in hazardous material suits working in a second floor apartment.

"It was all gas masks and the door was open and there were hoses in there," Lehman said.

Sandalo Dietrich would not say specifically why the FBI was searching the apartment.

"Information we developed led us to believe this was a productive spot to search," she said.

Two letters containing the substance were intercepted at the downtown Spokane post office Tuesday.

The Postal Service has received no other reports of similar letters, said Jeremy Leder of the Postal Inspection Service on Saturday.

In a statement following the discovery, the Postal Service said the "crude form of the ricin suggests that it does not present a health risk to U.S. Postal Service personnel or to others who may have come in contact with the letter."

The Spokane investigation comes a month after letters containing ricin were addressed to President Barack Obama, a U.S. senator and a Mississippi judge. A Mississippi man has been arrested in that case.

Chinese premier visits India to boost ties

NEW DELHI (AP) ? Just weeks after a tense border standoff, China's new premier visited India on Sunday on his first foreign trip as the neighboring giants look to speed up efforts to settle a decades-old boundary dispute and boost economic ties.

China says Premier Li Keqiang's choice of India for his first trip abroad since taking office in March shows the importance Beijing attaches to improving relations with New Delhi.

"We think very highly of this gesture because it is our view that high-level political exchanges between our two countries are an important aspect and vehicle for our expanded cooperation," said India's external affairs ministry spokesman, Syed Akbaruddin.

Jasjit Singh, a defense analyst and director of the Center for Strategic and International Studies in New Delhi, said last month's border standoff was unlikely to overshadow Li's three-day visit, the first stop of a foreign tour in which he will also visit Pakistan, Switzerland and Germany.

Singh said Indian and Chinese leaders are likely to review border talks that have failed to produce a breakthrough despite 15 rounds of discussions over the past 10 years. The two sides also will probably discuss working together in Afghanistan after next year's U.S. pullout and cooperation with Southeast Asian countries, he said.

But tensions run high between the two nations. China already sees itself as Asia's great power, while India hopes its increasing economic and military might ? though still far below its neighbor's ? will eventually put it in the same league.

While China has worked to shore up relationships with Nepal and Sri Lanka in India's traditional South Asian sphere of influence, India has been venturing into partnerships with Southeast Asian nations.

Other irritants remain in the bilateral relationship. China is a longtime ally and weapons supplier to Pakistan, India's bitter rival. Also, the presence in India of Tibetan spiritual leader the Dalai Lama and the self-declared Tibetan government-in-exile is a source of tension. China accuses the Dalai Lama of wanting to split Tibet off from the rest of China, but he says he seeks more autonomy for Tibetans, not independence.

Unresolved border issues between the two nations have flared as well.

In last month's incident, India said Chinese troops crossed the countries' de facto border on April 15 and pitched camp in the Depsang valley in the Ladakh region of eastern Kashmir. New Delhi responded with diplomatic protests and then moved its soldiers just 300 meters (yards) from the Chinese position.

The two sides negotiated a peaceful end to the standoff by withdrawing troops to their original positions in the Ladakh area.

Gautam Bambawale, a senior external affairs ministry official, said Saturday that India and China are negotiating a Border Defense Cooperation Agreement, but declined to give details. Indian media reports said the agreement proposes a freezing of troop levels in the disputed border region as the two countries make efforts to settle the issue.

Bambawale also said Indian and Chinese officials recently held talks in Beijing on the future of Afghanistan. China, India and Russia have discussed the matter trilaterally with the idea of giving full support to Afghanistan's government as it makes the transition following the withdrawal of U.S. forces in 2014.

Li was to meet with Indian Prime Minister Manmohan Singh later Sunday and attend a dinner hosted by Singh.

Delegation-level talks between the two sides are scheduled for Monday. Li is to attend a business summit in Mumbai, India's financial capital, among other activities.

The border spat last month prompted the Indian opposition and media to pressure the government to take on China and call off Li's visit. The government, however, chose to go ahead with the trip, highlighting its policy of trying to widen areas of cooperation with China while attempting to resolve key differences.

China has become India's biggest trading partner, with two-way trade jumping from $5 billion in 2002 to nearly $75 billion in 2011, although that figure declined to $61.5 billion last year because of the global economic downturn. Trade remains heavily skewed in China's favor, another source of concern for India.

India and China have had chilly relations since they fought a brief but bloody border war in 1962.

India says China is occupying 38,000 square kilometers (15,000 square miles) of its territory in the Aksai Chin plateau in the western Himalayas, while China claims around 90,000 square kilometers (35,000 square miles) in India's northeastern state of Arunachal Pradesh.

Dorjee Tseten, director of Students for a Free Tibet, said Sunday that New Delhi police had declined permission for Tibetans to hold a demonstration against Li's visit.

"Tibetan activists are currently on the run evading imminent police arrest," he said in a statement, complaining of a heavy police presence in a New Delhi area where a large number of Tibetans-in-exile live.

Police detained a Tibetan man as he tried to burn the Chinese flag near China's embassy in the Indian capital.

Police, however, allowed about two dozen members of Shiv Sena, a Hindu right-wing political party, to demonstrate near India's Parliament, where they burned an effigy of the Chinese premier.

"Go back, go back," chanted the protesters, who also carried placards urging the Indian government to respond toughly to China's alleged border incursion. The powerful regional party held power in Mumbai from 1995 to 2000.

They battle it out weekly on the Billboard charts, and now they're competing at the Billboard Music Awards.

Today's biggest stars ? from Taylor Swift to fun. to Maroon 5 ? are the key finalists at Sunday's awards show, airing live from MGM Grand Garden Arena in Las Vegas on ABC. Those acts are up for 11 awards each; Rihanna, Carly Rae Jepsen and One Direction are up for 10, nine and eight trophies, respectively.

Most of the top stars will also blaze the stage, too, including Swift, Justin Bieber, Bruno Mars, Miguel, Macklemore & Ryan Lewis, Chris Brown, Selena Gomez and others.

Prince, who will receive the icon award, will also hit the stage, and Madonna, to be named top touring artist, will make an appearance.

Jepsen, whose nine nominations include top Hot 100 song for the ubiquitous "Call Me Maybe," top female artist and top new artist, will present an award this year.

"The Billboard Awards is kind of a nostalgic one for me because it was the first awards show I attended outside of Canada," the 27-year-old recalled in an interview. "I had never really done anything quite so big. And to be going back a year later, and to be nominated, and then to also being doing all the fun stuff like pick a dress, and see the party, and watch the show ? I feel just lucky to be involved."

Jepsen's mentor, Bieber, is up for the night's biggest award, top artist. Other nominees include Swift, Rihanna, One Direction and Maroon 5. Swift is the only U.S. act nominated for top Billboard 200 album for her multiplatinum "Speak Now," which will compete with One Direction's first and second albums ? "Up All Night" and "Take Me Home" ? Mumford & Sons' "Babel" and Adele's 10 million-selling "21," which won the award last year.

Bieber, Swift and Mars are also up for the fan-voted milestone award.

Comedian-actor Tracy Morgan will host the Billboard Music Awards, which is celebrating its third year back on the scene following a five-year break.

Jepsen, whose new single "Tonight I'm Getting Over You" features Nicki Minaj, said she's excited to see the rapper perform with Lil Wayne on Sunday, but she's also happy to be in her seat and not onstage.

"I can remember being like just a big bundle of nerves last time," she said. "I've had a year of experience under my belt, and I'll probably still be nervous, but I'll be way more excited than anything."

Jennifer Lopez, The Band Perry, Pitbull, Christina Aguilera, Ed Sheeran, David Guetta and Kacey Musgraves will also perform Sunday night. Presenters include Shania Twain, Psy, Celine Dion, Miley Cyrus and CeeLo Green.

Verizon cuts prepaid plan prices, piles on more data

BENGHAZI (Reuters) - Armed groups attacked military posts in Libya's second city Benghazi with bombs and a rocket-propelled grenade, an army commander said on Saturday. Nearly two years after the uprising that ended Muammar Gaddafi's 42-year rule, the government still exerts little control over the armed brigades that helped overthrow him. Oil-producer Libya is largely split into fiefdoms of such brigades that are competing for influence. No one was hurt in the four overnight attacks on three Benghazi army posts, said the military commander, Hamed Belkhair. ...

College Women Don't Need to Binge to Over-Drink

College guys may outdrink women on any given night, but new research finds that the ladies are more likely than their male counterparts to exceed weekly alcohol limits.

During the academic year, about 65 percent of the freshman women in the study drank more than the seven-drink weekly limit recommended for women by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), according to the new research published today (May 17) in the journal Alcoholism: Clinical and Experimental Research. In comparison, 60 percent of men exceeded their recommended limit of 14 drinks weekly.

Women also blew past their weekly limits more frequently than did men, with the average woman drinking more than the recommended amount in 15 percent of the weeks in a school year, By comparison, the average guy exceeded the limit during just 12 percent of the weeks in the school year.

The genders exceeded daily drinking limits by similar amounts, however, the researchers found. The NIAAA recommends women drink no more than three drinks daily, and men no more than four.

"We do know that women are much more likely to have risk for disease at much lower levels of alcohol consumption" than are men, study researcher Bettina Hoeppner, a psychologist at Harvard Medical School's Center for Addiction Medicine, told LiveScience. "I don't think that's information that's readily available to college students, or something they really think about." [10 Easy Paths to Self Destruction]

Drinking risks

The NIAAA ?based its recommendations on the fact that women absorb alcohol more efficiently than men, and have lower body weight, so on average, their limits are stricter.

College students are often warned of the dangers of binging on alcohol, but few programs warn that chronic drinking also comes with risks, such as liver disease, cancer and heart disease ? even if it doesn't include binge drinking.

Hoeppner and her colleagues wanted to understand how drinking behaviors change over the college years. They recruited 992 incoming freshman at three northeastern universities. Over the course of the entire academic year, the students filled out biweekly email surveys about their recent alcohol consumption.

The results revealed that exceeding alcohol guidelines is common for college students: About 65 percent did so at least once, and 85 percent of those who reported ever drinking said they had drunk to excess at some point. ?

The finding that women exceeded weekly limits more than men did was concerning, Hoeppner said, particularly because men became less and less likely to exceed those limits as the year wore on, while women showed no such decrease.

Alcohol education

Part of the problem may be the gap between what women are told is safe to drink daily, compared with what men are told. On a single day, women can drink 80 percent of what men drink (three drinks to men's four). Over the course of a week, though, a woman should drink no more than half of what's safe for a man, to avoid heightened risk of chronic disease, the NIAAA finds.

Since seven drinks is a woman's safe limit for the week, a nightly glass of wine with dinner, and two drinks each on Friday and Saturday night can send a woman over the top, Hoeppner said.

"They're not getting drunk at any point. They're not binge drinking," she said of such a pattern. The findings suggest, however, that students need more education on the health risks of chronic drinking, Hoeppner said.

"I think it's important to at least in some way provide some education so that women don't establish unhealthy drinking patterns as they leave college," Hoeppner said.

Streetlight Manifesto: Ungrateful

Streetlight Manifesto's new record, The Hands That Thieve, is an instant classic in the ever-shrinking world of really stellar ska music simply by virtue of being a Streetlight Manifesto album. But what "Ungrateful" brings to the table is something a little subtler; it's a great Catch 22 song.

"Ungrateful" harkens back to the spring of 1998 with a sort of alarming intensity. Its earnestly self-defeated lyrics contrasted against an utterly triumphant melody?mandatory shout-chorus included?check off all the most important of boxes on the ska-checklist. It's a delightfully pared-down ditty on an album otherwise filled with more characteristically (and characteristically awesome) Streetlight songs.

But basically what I am trying to say here is that this is a good song; listen to it. And if you're a fan, the rest of the album is fantastically catchy too. Check it out and you'll be glad you did. [Spotify, Amazon, iTunes]

Afghan police chief shot dead outside home

KABUL, Afghanistan (AP) ? Motorcycle-riding gunmen assassinated a police chief in front of his house after he led an anti-Taliban campaign in western Afghanistan, an official said Saturday.

Police Chief Abdul Ghani was leaving his driveway in his car outside his home in Farah province when the two raced up and opened fire.

Provincial spokesman Abdul Rahman Zhawandai said that Ghani was rushed to hospital after the attack Friday night but died of his wounds.

Ghani had recently launched a crackdown against insurgents in his district of Khaki Safad that resulted in the killing and capture of several Taliban leaders, Zhawandai said.

"Because he was an active commander in this district, he was a target of the Taliban," he said.

In the same province Saturday morning, four Afghan army soldiers died in Bakwa district when their vehicle hit a roadside bomb, the Defense Ministry said in a statement.

Afghan security forces and government officials are targeted by the Taliban to weaken the government of President Hamid Karzai ahead of the withdrawal of most international troops by the end of 2014.

Idaho man charged in Uzbekistan terrorism plot

BOISE, Idaho (AP) ? He was a Russian-speaking truck driver in Idaho, among hundreds of Uzbekistan natives for whom the state has become a sanctuary from violence in their home country in the past decade.

But federal officials say in an indictment that Fazliddin Kurbanov also was teaching people to build bombs that would target public transportation.

It's unclear whether those alleged targets were domestic or abroad ? or even how far Kurbanov would have gone. Prosecutors said Friday only that they believe he is no longer a threat.

Kurbanov, 30, was arrested Thursday during a raid of his small apartment south of Boise's downtown.

Prosecutors charged him with felonies in Idaho and Utah after an extensive investigation into his activities late last year and this year. They allege those activities included assisting a militant group in his home, Uzbekistan, a Central Asian country with a southern border with Afghanistan.

"Given his arrest, we believe any potential threat he posed has been contained," U.S Attorney Wendy Olson said. She noted the investigation is ongoing but declined to say whether federal agents are pursuing additional arrests.

Kurbanov said little Friday during his first court appearance, where he pleaded not guilty with help from an interpreter and a federally appointed defense attorney. Kurbanov, who wore a jail jumpsuit, had dark hair and a beard that was much shorter than the one pictured in his Idaho driver's license.

Kurbanov lists Uzbek as his first language and Russian as his second in court documents. Federal officials said they will enlist the help of an interpreter again Tuesday when he appears for his detention hearing.

Until then, Kurbanov will be held in the Ada County Jail. His trial on the three counts filed in Idaho is scheduled for July 2.

Richard Rubin, Kurbanov's lawyer, declined to comment.

Uzbeks began coming to Idaho's two refugee settlement centers, in Boise and Twin Falls, in 2003, said Jan Reeves, director of the Idaho Office for Refugees. The centers connect them with services such as language classes and help finding work.

There are now about 650 Uzbeks living in Idaho, largely split between the two cities.

Reeves declined to comment on Kurbanov but said the flow of immigrants from Uzbekistan escalated around 2005, when a violent clash between protesters and the government left several hundred dead.

Kurbanov was issued a Social Security number in Idaho in 2009. He has been living in the United States legally, federal officials said, but his immigration status and his reason for being in Idaho is unclear.

Kurbanov told authorities he had a job driving trucks and listed his only assets as used cars and a small amount of cash in checking and savings accounts.

On Friday, the apartment where he is believed to have lived had a sign on the door saying "Please respect our privacy." Nobody responded to a knock. Many immigrants from numerous countries live in the apartment complex, a series of two-level buildings across from a public high school.

Olson said she has seen Internet comments blaming Idaho's Muslim community since Kurbanov's arrest, something she called inappropriate. "These charges shouldn't be seen as a reflection on that community," Olson said.

About 90 percent of Uzbeks in their home country are Muslim.

Representatives of the Islamic Center of Boise, a meeting area for the region's Muslim community, didn't immediately return a phone call Friday.

The Idaho indictment charges Kurbanov with one count of conspiracy to provide material support to a foreign terrorist organization and one count of conspiracy to provide material support to terrorists and possession of an unregistered explosive device.

It alleges that between August and May, he knowingly conspired with others to provide resources, including computer software and money, to the Islamic Movement of Uzbekistan, which the U.S. has identified as a terrorist organization. The group's purpose is to overthrow the government of Uzbekistan, said David B. Barlow, U.S. attorney in Utah. The alleged co-conspirators were not named.

The indictment also alleges Kurbanov provided material support to terrorists, knowing it was to be used in preparation for a plot involving the use of a weapon of mass destruction.

On Nov. 15, Kurbanov possessed a series of parts intended to be converted into a bomb, including a hollow hand grenade and aluminum powder, according to the indictment.

A separate federal grand jury in Utah charged Kurbanov with distributing information about bombs. For 10 days in January, Kurbanov taught and demonstrated how to make an "explosive, destructive device and weapon of mass destruction," the document states.

The Utah indictment, to be handled separately after the Idaho prosecution is resolved, alleges Kurbanov provided recipes for how to make improvised explosive devices and went on instructional shopping trips in Utah to help illustrate how to make the devices, Barlow said. Kurbanov also showed Internet videos on the topic, Barlow said.

Although the Islamic Movement of Uzbekistan started in the 1990s with the stated aim of overthrowing the Uzbek regime and establishing an Islamic government, its goals have expanded to create a broader Islamic influence in Central Asia.

The movement's fighters have a presence in Afghanistan's northern provinces and in Pakistan's Waziristan province. U.S. and Afghan officials say al-Qaeda has been building ties with the IMU.

Last year, an Uzbek named Ulugbek Kodirov was sentenced to at least 15 years in prison in Alabama for plotting to shoot President Barack Obama. Kodirov pleaded guilty, saying he was acting for the IMU.

Two other Uzbek nationals were arrested in 2012, one in Colorado and another in Pennsylvania, on what the FBI said were related terrorism charges.

According to Idaho's courts, Kurbanov has no criminal convictions but was ticketed for speeding violations twice last year.

Agonizing family choice in Japanese film at Cannes festival

By Alexandria Sage

CANNES (Reuters) - A film about baby-switching by Japan's Kore-eda Hirokazu that ponders nature versus nurture premiered at the Cannes film festival on Saturday, joining an Iranian challenger as contenders for the top prize.

"Soshite Chichi Ni Naru" ("Like Father, Like Son") is one of two Japanese films out of the international roster of 20 vying to take home the Palme d'Or prize on May 26 from the world's largest film festival being held on the French Riviera.

Japan has won four times before, most recently in 1997 with Shohei Imamura's "Unagi" ("The Eel"). Its other offering this year is the stunt-filled police thriller "Wara No Tate" ("Shield of Straw") by Takashi Miike.

"Soshite Chichi Ni Naru" stars singer and actor Masaharu Fukuyama as workaholic Ryota who, along with his docile wife Midori, played by Machiko Ono, is grooming his 6-year-old son Keita for success.

Their outwardly picture-perfect family life is shattered one day after the hospital where Keita was born informs them they made a mistake and Keita is not their biological son.

"Why didn't I see it? I'm a mother!" laments Midori after the revelation, which forces the couple into an agonizing decision - whether to keep Keita as their own, or make a swap.

The film finds moments of humor and humanity when Ryota and Midori meet the couple, played by Yoko Maki and Lily Franky, who have brought up their biological son.

Shopkeepers from a different class, they horrify the sensibilities of Ryota, who sees them as bumbling simpletons incapable of rearing his son.

But the first impression is eclipsed by recognition of their kindness and obvious love for their children.

"I wanted to create this total upheaval in the morality of the main character," Kore-eda told journalists. "I wanted to create a real shock in his mind."

"Soshite Chichi Ni Naru" is Kore-eda's fourth film to compete at Cannes, his "Kuki Ningyo" ("Air Doll") having been included in the "Un Certain Regard" category for emerging directors in 2009.

Kore-eda's gentle film is a contrast to many over the first four days of competition that have been marked by violence.

Mexican film "Heli" includes a sickening torture sequence, while a man in Chinese film "Tian Zhu Ding" is driven to carry out a bloody rampage after failing to thwart corrupt officials.

"After suffering through a wash of nihilism in the official competition so far, it is a pleasure to experience a film-maker so at home to big-hearted humanism," wrote the Irish Times' Donald Clarke in a review.

A rival family drama, Le Passe ("The Past") by Iranian director Asghar Farhadi, also received critical praise after its premiere on Friday.

"The bookies probably still have Asghar Farhadi's The Past ahead in the race for the Palme d'Or," Clarke wrote.

He added that the warm reaction at a press screening of Kore-eda's film on Friday "suggests that the Japanese wizard may stand a sporting chance of taking home the trophy".

Rasmussen polls shows public knows little about immigration | The ...

Only ten percent of Americans know that 1 million legal immigrants arrive each year, according to a new poll.

One-in-eight Americans incorrectly believe the inflow of immigrants is only 250,000 people per year, while?56 percent of adults believe fewer legal immigrants arrive than than illegal immigrants, according to the May 16 poll by Rasmussen Reports.

In fact, the inflow of illegals from Mexico has dropped below 200,000, and may be less than the flow of illegal immigrants back home, according to a May report by the Pew Research Hispanic Center.

The inflow of illegal immigrants was roughly 600,000 persons a year during the boom period from 1995 to 2008, but has dropped since the economic crash in 2008, leaving the country with a population of at least 11 million illegal immigrants. Mexico provided roughly 70 percent of the illegal flow.

Companies bring in roughly 650,000 guest-workers each year to work for a few months or up to seven years, according to the Center for Immigration Studies. Another 50,000 guest-workers work in agriculture. The flow of guest workers ensures there?s a year-round population of more than 1 million guest workers in the country, most of whom have university degrees.

These big numbers rarely get published in articles about immigration, despite the controversy over the Senate?s pending rewrite of the immigration bill.

Advocates for the bill are reluctant to say how many people it will bring to the country.

But lead author Sen. Chuck Schumer, for example, says it will actually reduce the current inflow by reducing he arrival of illegal immigrants.?That?s the same pitch made by the Center for American Progress, a White House ally, which discounts the amnesty of 11 million illegal immigrants on the grounds that they?re already in the United States.

Opponents of the bill, such as Sen. Jeff Sessions, cite studies showing that the bill would boost the inflow beyond 30 million ? including at least 11 million illegal immigrants ? over the next decade, and roughly 1.5 million per year thereafter.

?It?s no surprise that voters don?t know a lot of specifics about immigration?policy? [because] what I?ve always found is that once people hear how high?immigration is, they get skeptical quick,? said Mark Krikorian, executive director of the Center for Immigration Studies.

Politicians have an incentive to talk about illegal immigration rather than legal immigration, he said. ?Politicians find it convenient to focus their rhetoric on illegal immigration while at the same time using legal immigration policy as a form of corporate welfare,? he said.

Thirty-two percent of Rasmussen?s respondents believe immigration is less than 1 million per year, and seven percent believe it is more than 2.5 million per year.?Fifty-one percent of 1,000 respondent in the poll said they don?t know how many people come into the country.

The sub-group with the most accurate understanding of the numbers is African-Americans, 23 percent of whom correctly estimated an inflow one million legal immigrants per year.

Stocks rise on hopeful signs for the US economy

(AP) ? Encouraging news about the U.S. economy extended the stock market's rally Friday.

Small-company stocks rose the most, a sign that investors are taking on more risk. Two companies soared in their stock-market debuts in the latest indication that the market for initial public offerings is reviving.

A gauge of future economic activity rose more than analysts had expected, as did a measure of consumer confidence, adding to evidence that the economy is steadily recovering.

Stocks closed higher for a fourth straight week. Indexes are at record levels after surging this year on optimism about the economy and record corporate earnings. The market is also being supported by ongoing stimulus from the Federal Reserve, which is keeping long-term borrowing costs at historically low levels.

"This slow but relatively steady growth, that keeps inflation in check and keeps interest rates low, is actually a pretty healthy environment for the stock market," said Liz Ann Sonders, chief investment strategist at Charles Schwab & Co. "Right now we are very optimistic."

General Motors rose $1.03, or 3.2 percent, to $33.42. The automaker's stock is trading above the $33 price of its November, 2010 initial public offering for the first time in two years.

Northrop Grumman gained $3.17, or 3.2 percent, to $82.19 after the defense contractor said its board approved the repurchase of another $4 billion in stock, and that it plans to buy back a quarter of its outstanding shares by the end of 2015.

The Dow Jones industrial average rose 121.18 points, or 0.8 percent, to 15,354.40. The index gained 1.6 percent for the week and is up 17.2 percent for the year.

The index started higher, then drifted through the rest of the morning. The index added to its gains in the afternoon, climbing about 70 points in the last two hours of the day.

The Standard & Poor' 500 index rose 15.65 points, or 1 percent, to 1,666.12. The gauge is up 2 percent this week and has gained 16.8 percent this year.

After some lackluster reports on the economy Thursday, including slowing manufacturing and an increase in applications for unemployment benefits, Friday's reports were a tonic for investors.

The Conference Board said its index of leading economic indicators rose 0.6 percent last month after a revised decline of 0.2 percent in March. The index is intended to predict how the economy will be doing in three to six months.

The University of Michigan's preliminary survey of consumer confidence climbed to 83.7. Economists had predicted that the gauge would climb to 76.8.

The strength of the rally in stocks has taken many by surprise, leaving investors waiting for a drop in prices to get into the market, said Jim Anderson, an investment specialist at JPMorgan. The S&P 500 index hasn't fallen for two consecutive days in a month.

"Everyone is waiting for a pullback," Anderson said. "Every client asks me, 'When are we getting a pullback?' With so many people waiting for it, and pouncing on it when it arrives, it's over so quickly."

As well as giving stocks a lift, the positive economic reports also pushed government bond yields higher. The yield on the 10-year Treasury rose to 1.96 percent from 1.88 percent Thursday as investors favored riskier assets.

The yield, which moves inversely to its prices, has jumped since May 3 after the government reported that hiring picked up sharply in April. The note started trading that day at 1.63 percent, its low for the year.

The move to riskier assets also gave small stocks a lift. The Russell 2000, an index of smaller companies, rose 10.94 points, or 1.1 percent, to 996.28. The index has surged this month and is performing better than both the Dow and the S&P 500 for the year. It's up 17.3 percent so far in 2013.

Small stocks are doing well partly because they are more focused on the U.S., which is recovering, and don't rely as much on sales from recession-plagued Europe, as larger companies do.

Gold fell for a seventh straight day, dropping $22.20, or 1.6 percent, to $1,364 an ounce. The precious metal is down almost 20 percent this year and has fallen out of favor as an alternative investment as the stock market has surged this year.

The demand for gold as an alternative asset is also being undermined by a recent surge in the U.S. dollar. The U.S. currency advanced against both the euro and the yen Friday. The ICE dollar index, which measures the strength of the U.S. currency against a group of six currencies, is at its highest in two years.

The price of oil rose 86 cents, or 0.9 percent, to $96.02 a barrel.

The Nasdaq composite climbed 33.72 points, or 1 percent, to 3,498. The technology-heavy stock index got a small boost from Facebook, which climbed 12 cents, or 0.5 percent, to $26.25 on the one-year anniversary of its initial public offering.

Facebook slumped in the first four months after its market debut on concern that it wasn't doing enough to develop mobile advertising. Despite recovering since then, it's still trading below its IPO price of $38.

Two software companies had more success in their stock market debuts on Friday. Marketo surged $10.10, or 77.7 percent, to $23.10 on its stock market debut. Tableau software rose $19.75, or 63.7 percent, to $50.75 on its first day of trading.

The standout performance made the two companies the two best performing IPOs of the year. So far, 22 companies have prices stock sales in May, making this the biggest month for stock market debuts since November 2007, according to Renaissance Capital.

Among other stocks making big moves;

? J.C. Penney fell 78 cents, or 4.2 percent, to $18.01 after the retailer reported a loss that was worse than analysts' already dismal estimates. The retailer is reeling from the fallout from a failed turnaround plan orchestrated by its former CEO Ron Johnson, who was ousted last month after less than a year and a half on the job.

? Autodesk fell $2.67, or 6.7 percent, to $37.11, after the design software company posted disappointing first-quarter results and lowered its forecasts for the year.

Afghan lawmakers block law on women's rights

(AP) ? Conservative religious lawmakers in Afghanistan blocked legislation on Saturday aimed at strengthening provisions for women's freedoms, arguing that parts of it violate Islamic principles and encourage disobedience.

The fierce opposition highlights how tenuous women's rights remain a dozen years after the ouster of the hard-line Taliban regime, whose strict interpretation of Islam once kept Afghan women virtual prisoners in their homes.

Khalil Ahmad Shaheedzada, a conservative lawmaker for Herat province, said the legislation was withdrawn shortly after being introduced in parliament because of an uproar by religious parties who said parts of the law are un-Islamic.

"Whatever is against Islamic law, we don't even need to speak about it," Shaheedzada said.

The Law on Elimination of Violence Against Women has been in effect since 2009, but only by presidential decree. It is being brought before parliament now because lawmaker Fawzia Kofi, a women's rights activist, wants to cement it with a parliamentary vote to prevent its potential reversal by any future president who might be tempted to repeal it to satisfy hard-line religious parties.

The law criminalizes, among other things, child marriage and forced marriage, and bans "baad," the traditional practice of exchanging girls and women to settle disputes. It makes domestic violence a crime punishable by up to three years in prison and specifies that rape victims should not face criminal charges for fornication or adultery.

Kofi, who plans to run for president in next year's elections, said she was disappointed because among those who oppose upgrading the law from presidential decree to legislation passed by parliament are women.

Afghanistan's parliament has more than 60 female lawmakers, mostly due to constitutional provisions reserving certain seats for women.

There has been spotty enforcement of the law as it stands. A United Nations analysis in late 2011 found only a small percentage of reported crimes against women were pursued by the Afghan government. Between March 2010 and March 2011 ? the first full Afghan year the decree was in effect ? prosecutors filed criminal charges in only 155 cases, or 7 percent of the total number of crimes reported.

The child marriage ban and the idea of protecting female rape victims from prosecution were particularly heated subjects in Saturday's parliamentary debate, said Nasirullah Sadiqizada Neli, a conservative lawmaker from Daykundi province.

Neli suggested that removing the custom ? common in Afghanistan ? of prosecuting raped women for adultery would lead to social chaos, with women freely engaging in extramarital sex safe in the knowledge they could claim rape if caught.

Another lawmaker, Mandavi Abdul Rahmani of Barlkh province, also opposed the law's rape provision.

"Adultery itself is a crime in Islam, whether it is by force or not," Rahmani said.

He said the Quran also makes clear that a husband has a right to beat a disobedient wife as a last resort, as long as she is not permanently harmed. "But in this law," he said, "It says if a man beats his wife at all, he should be jailed for three months to three years."

Lawmaker Shaheedzada also claimed that the law might encourage disobedience among girls and women, saying it reflected Western values not applicable in Afghanistan.

"Even now in Afghanistan, women are running from their husbands. Girls are running from home," Shaheedzada said. "Such laws give them these ideas."

More freedoms for women are one of the most visible ? and symbolic ? changes in Afghanistan since the 2001 U.S.-led campaign that toppled the Taliban regime. While in power, the Taliban imposed a strict interpretation of Islam that put severe curbs on the freedom of women.

For five years, the regime banned women from working and going to school, or even leaving home without a male relative. In public, all women were forced wear a head-to-toe burqa, which covers even the face with a mesh panel. Violators were publicly flogged or executed.

Since the U.S.-led invasion in 2001, women's freedoms have improved vastly, but Afghanistan remains a deeply conservative culture, especially in rural areas.

Saturday's failure of the legislation in parliament reflected the power of religious parties but changed little on the ground, since the decree is still the law of the land, however loosely enforced. Kofi said the parliament decided to send the legislation to committee, and it could come to a vote again later this year.

"We will work on this law," she said. "We will bring it back."

Some activists, however, worry about potential changes to the law. Bringing the legislation before parliament also opened it up to being amended, leaving the possibility that conservatives will seek to weaken it by stripping out provisions they dislike ? or even vote to repeal it.

"There's a real risk this has opened a Pandora's box, that this may have galvanized opposition to this decree by people who in principle oppose greater rights for women," said Heather Barr, a researcher for Human Rights Watch.

That's true for lawmaker Rahmani, who said President Hamid Karzai should never have issued the decree and wants it changed, if not repealed.

"We cannot have an Islamic country with basically Western laws," he said.

EF-4 Tornadoes Are Rare For North Texas

GRANBURY (CBSDFW.COM) - It was the deadliest tornado outbreak in North Texas in over 30 years, and Granbury was the hardest-hit area in all of DFW. The National Weather Service estimated that 16 twisters landed across North Texas, and some of them were EF-4 tornadoes.

What does that mean?

Storms of that strength are extremely rare. In the last 50 years, North Texas has only seen six EF-4 tornadoes, about one each decade. And even the total number of twisters was rare. In the last 50 years, there have only been seven days with 10 or more tornadoes.

The six fatalities on Wednesday made it the deadliest North Texas tornado day since April 1982, when a storm ripped through Paris.

A survey team from the National Weather Service walked through the damage on Thursday to determine the classification information. They look at several factors when trying to determine the strength of any particular storm. An EF-4 tornado has winds over 200 mph, and there can be signs that such a strong storm has passed through a neighborhood.

The survey team looked for the total loss of well-built homes and business structures, and large trucks that were either flipped repeatedly or moved short distances. They also looked for trees that were debarked and snapped close to the ground, or uprooted altogether.

An EF-4 tornado levels homes and practically requires a storm shelter in order to survive. And when you look at some of the damage done by these powerful twisters on Wednesday, it is almost unbelievable that there were not more deaths.

Beautiful 'flowers' self-assemble in a beaker

May 16, 2013 ? "Spring is like a perhaps hand," wrote the poet E. E. Cummings: "carefully / moving a perhaps / fraction of flower here placing / an inch of air there... / without breaking anything."

With the hand of nature trained on a beaker of chemical fluid, the most delicate flower structures have been formed in a Harvard laboratory -- and not at the scale of inches, but microns.

These minuscule sculptures, curved and delicate, don't resemble the cubic or jagged forms normally associated with crystals, though that's what they are. Rather, fields of carnations and marigolds seem to bloom from the surface of a submerged glass slide, assembling themselves a molecule at a time.

By simply manipulating chemical gradients in a beaker of fluid, Wim L. Noorduin, a postdoctoral fellow at the Harvard School of Engineering and Applied Sciences (SEAS) and lead author of a paper appearing on the cover of the May 17 issue of Science, has found that he can control the growth behavior of these crystals to create precisely tailored structures.

"For at least 200 years, people have been intrigued by how complex shapes could have evolved in nature. This work helps to demonstrate what's possible just through environmental, chemical changes," says Noorduin.

The precipitation of the crystals depends on a reaction of compounds that are diffusing through a liquid solution. The crystals grow toward or away from certain chemical gradients as the pH of the reaction shifts back and forth. The conditions of the reaction dictate whether the structure resembles broad, radiating leaves, a thin stem, or a rosette of petals.

It is not unusual for chemical gradients to influence growth in nature; for example, delicately curved marine shells form from calcium carbonate under water, and gradients of signaling molecules in a human embryo help set up the plan for the body. Similarly, Harvard biologist Howard Berg has shown that bacteria living in colonies can sense and react to plumes of chemicals from one another, which causes them to grow, as a colony, into intricate geometric patterns.

Replicating this type of effect in the laboratory was a matter of identifying a suitable chemical reaction and testing, again and again, how variables like the pH, temperature, and exposure to air might affect the nanoscale structures.

The project fits right in with the work of Joanna Aizenberg, an expert in biologically inspired materials science, biomineralization, and self-assembly, and principal investigator for this research.

Aizenberg is the Amy Smith Berylson Professor of Materials Science at Harvard SEAS, Professor of Chemistry and Chemical Biology in the Harvard Department of Chemistry and Chemical Biology, and a Core Faculty Member of the Wyss Institute for Biologically Inspired Engineering at Harvard.

Her recent work has included the invention of an extremely slippery material, inspired by the pitcher plant, and the discovery of how bacteria use their flagella to cling to the surfaces of medical implants.

"Our approach is to study biological systems, to think what they can do that we can't, and then to use these approaches to optimize existing technologies or create new ones," says Aizenberg. "Our vision really is to build as organisms do."

To create the flower structures, Noorduin and his colleagues dissolve barium chloride (a salt) and sodium silicate (also known as waterglass) into a beaker of water. Carbon dioxide from air naturally dissolves in the water, setting off a reaction which precipitates barium carbonate crystals. As a byproduct, it also lowers the pH of the solution immediately surrounding the crystals, which then triggers a reaction with the dissolved waterglass. This second reaction adds a layer of silica to the growing structures, uses up the acid from the solution, and allows the formation of barium carbonate crystals to continue.

"You can really collaborate with the self-assembly process," says Noorduin. "The precipitation happens spontaneously, but if you want to change something then you can just manipulate the conditions of the reaction and sculpt the forms while they're growing."

Increasing the concentration of carbon dioxide, for instance, helps to create 'broad-leafed' structures. Reversing the pH gradient at the right moment can create curved, ruffled structures.

Noorduin and his colleagues have grown the crystals on glass slides and metal blades; they've even grown a field of flowers in front of President Lincoln's seat on a one-cent coin.

"When you look through the electron microscope, it really feels a bit like you're diving in the ocean, seeing huge fields of coral and sponges," describes Noorduin. "Sometimes I forget to take images because it's so nice to explore."

In addition to her roles at Harvard SEAS, the Department of Chemistry and Chemical Biology, and the Wyss Institute, Joanna Aizenberg is Director of the Kavli Institute for Bionano Science and Technology at Harvard and Director of the Science Program at the Radcliffe Institute for Advanced Study.

Coauthors included Alison Grinthal, a research scientist at Harvard SEAS, and L. Mahadevan, who is the Lola England de Valpine Professor of Applied Mathematics at SEAS, Professor of Organismic and Evolutionary Biology and of Physics, and a Core Faculty Member at the Wyss Institute.

The project was supported by National Science Foundation grants to the Harvard Materials Research Science and Engineering Center (DMR-0820484) and the Harvard Center for Nanoscale Systems (ECS-0335765); and by the Netherlands Organization for Scientific Research.
