Healthier schools: Goodbye candy and greasy snacks


WASHINGTON (AP) — Goodbye candy bars and sugary cookies. Hello baked chips and diet sodas.


The government for the first time is proposing broad new standards to make sure all foods sold in schools are more healthful, a change that would ban the sale of almost all candy, high-calorie sports drinks and greasy foods on campus.


Under new rules the Department of Agriculture proposed Friday, school vending machines would start selling water, lower-calorie sports drinks, diet sodas and baked chips instead. Lunchrooms that now sell fatty "a la carte" items like mozzarella sticks and nachos would have to switch to healthier pizzas, low-fat hamburgers, fruit cups and yogurt.


The rules, required under a child nutrition law passed by Congress in 2010, are part of the government's effort to combat childhood obesity. While many schools already have made improvements in their lunch menus and vending machine choices, others still are selling high-fat, high-calorie foods.


Under the proposal, the Agriculture Department would set fat, calorie, sugar and sodium limits on almost all foods sold in schools. Current standards already regulate the nutritional content of school breakfasts and lunches that are subsidized by the federal government, but most lunch rooms also have "a la carte" lines that sell other foods. And food sold through vending machines and in other ways outside the lunchroom has not been federally regulated.


"Parents and teachers work hard to instill healthy eating habits in our kids, and these efforts should be supported when kids walk through the schoolhouse door," said Agriculture Secretary Tom Vilsack.


Most snacks sold in school would have to have less than 200 calories. Elementary and middle schools could sell only water, low-fat milk or 100 percent fruit or vegetable juice. High schools could sell some sports drinks, diet sodas and iced teas, but the calories would be limited. Drinks would be limited to 12-ounce portions in middle schools, and 8-ounce portions in elementary schools.


The standards will cover vending machines, the "a la carte" lunch lines, snack bars and any other foods regularly sold around school. They would not apply to in-school fundraisers or bake sales, though states have the power to regulate them. The new guidelines also would not apply to after-school concessions at school games or theater events, goodies brought from home for classroom celebrations, or anything students bring for their own personal consumption.


The new rules are the latest in a long list of changes designed to make foods served in schools more healthful and accessible. Nutritional guidelines for the subsidized lunches were revised last year and put in place last fall. The 2010 child nutrition law also provided more money for schools to serve free and reduced-cost lunches and required more meals to be served to hungry kids.


Iowa Sen. Tom Harkin, a Democrat, has been working for two decades to take junk foods out of schools. He calls the availability of unhealthful foods around campus a "loophole" that undermines the taxpayer money that helps pay for the healthier subsidized lunches.


"USDA's proposed nutrition standards are a critical step in closing that loophole and in ensuring that our schools are places that nurture not just the minds of American children but their bodies as well," Harkin said.


Last year's rules faced criticism from some conservatives, including some Republicans in Congress, who said the government shouldn't be telling kids what to eat. Mindful of that backlash, the Agriculture Department exempted in-school fundraisers from federal regulation and proposed different options for some parts of the rule, including the calorie limits for drinks in high schools, which would be limited to either 60 calories or 75 calories in a 12-ounce portion.


The department also has shown a willingness to work with schools to resolve complaints that some new requirements are hard to meet. Last year, for example, the government relaxed some limits on meats and grains in subsidized lunches after school nutritionists said they weren't working.


Schools, the food industry, interest groups and other critics or supporters of the new proposal will have 60 days to comment and suggest changes. A final rule could be in place as soon as the 2014 school year.


Margo Wootan, a nutrition lobbyist for the Center for Science in the Public Interest, says surveys done by her organization show that most parents want changes in the lunchroom.


"Parents aren't going to have to worry that kids are using their lunch money to buy candy bars and a Gatorade instead of a healthy school lunch," she said.


The food industry has been onboard with many of the changes, and several companies worked with Congress on the child nutrition law two years ago. Major beverage companies have already agreed to take the most caloric sodas out of schools. But those same companies, including Coca-Cola and PepsiCo, also sell many of the non-soda options, like sports drinks, and have lobbied to keep them in vending machines.


A spokeswoman for the American Beverage Association, which represents the soda companies, says they already have greatly reduced the number of calories kids are consuming at school by pulling out the high-calorie sodas.

Gov's Handling of Sandusky Case Under Investigation













The newly-elected attorney general of Pennsylvania is going after the state's governor, Tom Corbett, who was attorney general when child sex allegations against Penn State coach Jerry Sandusky were first brought forward.


Kathleen Kane, a Democrat who was sworn in as attorney general on Jan. 15, said that she will name a special prosecutor in the coming days to investigate Corbett's handling of the Sandusky case. Corbett is a Republican.


The investigation will look specifically at why it took the attorney general's office three years to bring criminal charges against Sandusky while he continued to have access to children.


"Attorney General Kane will appoint a special prosecutor to lead the office's internal investigation into how the Sandusky child abuse investigation was handled by the Office of the Attorney General," Kane's office said in a statement released today.


Corbett's attorney general's office was first notified of the allegations against Sandusky in 2008 when a high school student told his mother and school that Sandusky had molested him. The local district attorney passed the allegation on to the attorney general, then Corbett. Corbett convened a grand jury.

It wasn't until 2011 that sex abuse charges were filed against Sandusky while Corbett had since become governor. Sandusky was convicted on 45 counts of sex abuse in June 2012.


The charges sent shockwaves throughout Pennsylvania, as Penn State's president, two top officials, and legendary coach Joe Paterno all lost their jobs over the scandal.


"Why did it take 33 months to get Sandusky off the streets? Was the use of a grand jury the right decision? Why were there so few resources dedicated to the investigation? Were the best practices implemented?" the statement from Kane's office read.


"At the end of this investigation, we will know the answers to these questions and be able to tell the people of Pennsylvania the facts and give them answers that they deserve," the statement said.


Describing an interview Kane gave the New York Times, the Times said Kane suggested that Corbett did not want to upset voters or donors in the Penn State community before his gubernatorial run in 2009.


Corbett has denied those suggestions. His office did not immediately return calls for comment.


Kane's office preemptively fought back against the idea that the investigation is politically motivated. Kane, a Democrat, defeated the incumbent attorney general, Linda Kelly, a Republican in November 2011. Corbett is a Republican.


"The speculation that this is about politics is insane," a staff member in Kane's office told ABC News today. "You go anywhere in Pennsylvania and anywhere across the country and you'll find individuals asking, 'why did it take three years? Why was there a grand jury? Why make these kids talk to 30 different people about what happened?"

Explosion at Mexican oil giant Pemex headquarters kills 25


MEXICO CITY (Reuters) - A powerful explosion rocked the Mexico City headquarters of state-owned oil giant Pemex on Thursday, killing at least 25 people, injuring more than 100 and trapping others inside.


The mid-afternoon blast in a neighboring building shattered the lower floors of the downtown tower, throwing debris into the streets and sending frightened workers running outside.


A government official, speaking on condition of anonymity, said a preliminary line of investigation was that the blast came from a gas boiler that exploded in the adjacent Pemex building. But the cause was still being determined, the official added.


The explosion at the building complex, where thousands of Pemex employees worked, was the latest in a series of serious safety problems to hit Mexico's national oil monopoly.


Interior Minister Miguel Angel Osorio Chong said the blast killed at least 25 people, injured over 100, and that the number of casualties could rise.


Rescue workers were still searching for employees trapped inside the Pemex skyscraper on Thursday night. At least one person had been rescued alive, Osorio Chong said.


Mauricio Parra, a paramedic at the scene, said that as many as 100 people could be trapped at the offices of Pemex, a national institution that President Enrique Pena Nieto's administration has pledged to reform this year.


Police quickly cordoned off the building, and television images showed the explosion caused major damage to the ground floor and blew out windows on the lower floors of the tower.


"You could feel it all through the building," said Mario Guzman, a Pemex worker who was on the 10th floor of the building, which is more than 50 stories high.


First mistaking the blast for an earthquake, Guzman, who said he escaped after running down the stairs, feared the building would collapse on top of him and his colleagues, "and that we would end up like a sandwich."


Pemex said initially the tower was evacuated due to a problem with its electricity supply. It then said there had been an explosion, but did not say what caused it.


The Pemex blast occurred shortly before many workers were due to end their shifts at the complex.


The company said its business would not be affected by the incident and that it would continue to operate normally.


FORCE OF LAW


Earlier in the evening, Pena Nieto, who took office in December, went to the scene and said the explosion would be thoroughly investigated. He vowed to apply "the force of the law" if anyone was found to be responsible for it.


Mexican media reported that after the blast, security officials carried out a precautionary search of Congress for explosive devices, but found nothing.


Asked about this, Osorio Chong said normal security procedures were being followed, but added that "additional care" was being taken while the blast was being cleared up.


Helicopters buzzed around the building and lines of fire trucks sped to the entrance, while emergency workers ferried injured people through wreckage strewn on the street.


Search-and-rescue dogs were sent into the skyscraper, a Mexico City landmark that sports a distinctive "hat" on top.


Some families of people working in the tower were impatient for news about missing relatives.


Gloria Garcia, 53, herself a Pemex worker who was not in the building during the explosion, came to see if she could track down her son, who worked in one of the floors hit.


"I'm calling his phone and he's not answering," Garcia said, weeping as she called repeatedly on her phone. "Nobody knows anything. They won't let me through. I want to see my son whatever state he's in."


DEADLY ACCIDENTS


Pemex has experienced a number of deadly accidents in recent years and lesser safety problems have been a regular occurrence. In September, 30 people died after an explosion at a Pemex natural gas facility in northern Mexico.


More than 300 were killed when a Pemex natural gas plant on the outskirts of Mexico City exploded in 1984.


Eight years later, about 200 people were killed and 1,500 injured after a series of underground gas explosions in Guadalajara, Mexico's second biggest city. An official investigation found Pemex was partly to blame.


Alberto Islas, a security analyst at consultancy Risk Evaluation, said the explosion at the Pemex offices was another blot against the company's safety record.


"We've seen this time and again at Pemex. They don't have a well-integrated policy," Islas said, noting it would probably take several hours before investigators would be able to determine the cause of the explosion.


Pemex, a symbol of Mexican self-sufficiency since the oil industry was nationalized in 1938, has been held back by inefficiency and corruption and by the burden it shoulders of providing about a third of federal tax revenues.


Pena Nieto has pledged to open up the company to more private investment to improve its performance.

Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos













Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.


The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."


Arias' attorneys introduced as evidence photos that Alexander took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.


Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.


Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.


"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.


"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Jodi Arias Murder Trial: Defense's First Day of Witnesses Watch Video





Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.


Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.


Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."


"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.


Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.


In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.


"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"


"She would not be ready to be baptized in that case," Freeman said.


"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.


"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."


Freeman said that Alexander never confessed to having a sexual relationship with Arias.


Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.


The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.

French troops deployed in last Mali rebel strongholds


DOUENTZA, Mali/PARIS (Reuters) - French troops seized the airport in Mali's northern town of Kidal, the last urban stronghold held by Islamist insurgents, as they moved to wrap up the first phase of a military operation to wrest northern Mali from rebel hands.


France has deployed some 4,500 troops in a three-week ground and air offensive to break the Islamist rebels' 10-month grip on major northern towns. The mission is aimed at heading off the risk of Mali being used as a springboard for jihadist attacks in the wider region or Europe.


The French military plans to gradually hand over to a larger African force, tasked with rooting out insurgents in their mountain redoubts near Algeria's border.


Defense Minister Jean-Yves Le Drian said French forces using planes and helicopters defied a sandstorm late on Tuesday to capture the airport but had been prevented by the bad weather from entering the town itself.


"The terrorist forces are pulling back to the Adrar des Ifoghas mountains which are difficult to access," Le Drian told a news conference. "There is support from Chadian and Nigerian troops coming from the south."


The deployment of French troops to remote Kidal puts them in direct contact with pro-autonomy Tuareg MNLA rebels, whose rebellion last year was hijacked by the Islamist radicals. Le Drian said France had established good relations with local Tuareg chieftains before sending in troops.


MNLA leaders say they are ready to fight al Qaeda but many Malians, including the powerful military top brass in the capital Bamako, blame them for the division of the country. They view Paris' liaisons with the Tuaregs with suspicion.


French and Malian troops retook the major Saharan trading towns of Gao and Timbuktu at the weekend.


There were fears that many thousands of priceless ancient manuscripts held in Timbuktu, a UNESCO World Heritage site, might have been lost during the rebel occupation, but experts said the bulk of the texts were safe.


The United States and European governments strongly support the Mali intervention and are providing logistical and surveillance backing but do not intend to send combat troops.


The MNLA rebels, who want greater autonomy for the desert north, said they had moved fighters into Kidal after Islamists left the town earlier this week.


"For the moment, there is a coordination with the French troops," said Moussa Ag Assarid, the MNLA spokesman in Paris.


A spokesman for the Malian army said its soldiers were securing Gao and Timbuktu and were not heading to Kidal.


The MNLA took up arms against the Bamako government a year ago, seeking to carve out a new independent desert state.


After initially fighting alongside the Islamists, by June they had been forced out by their better armed and financed former allies, who include al Qaeda North Africa's wing, AQIM, a splinter wing called MUJWA and Ansar Dine, a Malian group.


RISK OF ATTACKS, KIDNAPPINGS


As the French wind up the first phase of their offensive, doubts remain about just how quickly the U.N.-backed African intervention force can be fully deployed in Mali to hunt down the retreating al Qaeda-allied insurgents. Known as AFISMA, the force is now expected to exceed 8,000 troops.


Foreign Minister Laurent Fabius said France's military operation, codenamed Serval (Wildcat), was planned as a lightning mission lasting a few weeks.


"Liberating Gao and Timbuktu very quickly was part of the plan. Now it's up to the African countries to take over," he told the Le Parisien daily. "We decided to put in the means and the necessary number of soldiers to strike hard. But the French contingent will not stay like this. We will leave very quickly."


One French soldier has been killed in the mission, and Fabius warned that things could now get more difficult, as the offensive seeks to flush out insurgents with experience of fighting in the desert from their wilderness hideouts.


"We have to be careful. We are entering a complicated phase where the risks of attacks or kidnappings are extremely high. French interests are threatened throughout the entire Sahel."


An attack on the In Amenas gas plant in Algeria earlier this month by Islamist fighters opposing the French intervention in Mali led to the deaths of dozens of foreign hostages and raised fears of similar reprisal strikes across North and West Africa.


NEED FOR RECONCILIATION


The French operation has destroyed the Islamists' training camps and logistics bases but analysts say a long term solution for Mali hinges on finding a political settlement between the northern communities and the southern capital Bamako.


Interim President Dioncounda Traore said on Tuesday his government would aim to hold national elections on July 31. Paris is pushing strongly for Traore's government to hold talks with the MNLA, which has dropped its claims for independence.


"The Malian authorities must begin without delay talks with the legitimate representatives of the northern population and non-terrorist armed groups that recognize Mali's integrity," French Foreign ministry spokesman Philippe Lalliot said.


After months of being kept on the political sidelines, the MNLA said they were in contact with West African mediators who are trying to forge a national settlement to reunite Mali.


"We reiterate that we are ready to talk with Bamako and to find a political solution. We want self-determination, but all that will be up to negotiations which will determine at what level both parties can go," Ag Assarid said.


There have been cases in Gao and Timbuktu and other recaptured towns of reprisal attacks and looting of shops and residences belonging to Malian Tuaregs and Arabs suspected of sympathizing with the MNLA and the Islamist rebels.

Manufacturing business sentiments expected to remain weak: EDB






SINGAPORE: Business sentiments in Singapore's manufacturing sector are expected to remain weak in the first half of this year, as slow global economic growth continues.

According to the latest survey by the Economic Development Board, a net weighted balance of 10 per cent of manufacturers anticipate a less favourable business situation in the period January to June this year, compared to the fourth quarter of 2012.

Within the manufacturing sector, EDB said the biomedical cluster is the most optimistic, with a net weighted balance of 7 per cent of firms anticipating better business prospects in the months ahead. Part of this optimism stems from the pharmaceutical segment which is foreseeing higher demand from overseas.

In the general manufacturing industries cluster, a net weighted balance of just one per cent of businesses project an improved performance in the first half of the year. This is due mainly to the food, beverages and tobacco segment, which is anticipating stronger demand due to seasonal factors such as the Lunar New Year.

On the other hand, the electronics cluster is the least upbeat about business prospects in the next two quarters. A net weighted balance of 28 per cent of electronics firms expect weak demand conditions to persist amid slow economic growth in Europe and US.

The precision engineering segment is also projecting a less favourable outlook on the back of weak equipment spending and low demand for precision components.

Meanwhile, business outlook for the chemical cluster is also weak. This is largely due to the petroleum segment, which is expecting refining margins to come under pressure with increased capacity from new plants overseas.

EDB said a net weighted balance of 10 per cent of manufacturers expect output to decline in the first quarter this year.

It added that employment prospects in the manufacturing sector in the first quarter of 2013 are likely to remain similar to the fourth quarter of 2012.

In particular, the transport engineering and general manufacturing industries clusters are most optimistic about employment opportunities between January and March 2013.

A weighted 45 per cent of the manufacturers said there are no limiting factors which could affect their ability to obtain direct export orders in the first quarter.

The weighted 48 per cent of firms that indicated export constraints cited price competition from overseas competitors, and economic and political conditions abroad as the most important limiting factors.

Vishwaroopam row: Want to wait before going to Supreme Court, Kamal Haasan says

CHENNAI: Actor-filmmaker Kamal Haasan said Thursday that he doesn't want to move the Supreme Court as of now because he hopes for a positive outcome for his movie "Vishwaroopam".

"I still have hope things may be settled with Tamil Nadu government. For now, I may wait before moving to Supreme Court," said Kamal.

On Jan 30, a Madras HC bench chaired by Justice Dharma Rao re-imposed the ban on the film and nullified the revocation of an earlier ban on the film by Justice K. Venkataraman on Jan 29.

The final hearing on the case is due February 6.

The Rs 95 crore espionage thriller was originally scheduled to release in Tamil and Telugu on Jan 25, but a day before the screenings, the Tamil Nadu government imposed a two-week ban on the film after some Muslim groups complained that some scenes in the film portrayed the community in a bad light.

Kamal on Wednesday also agreed to cut a few scenes that were pointed out as controversial to him by his Muslim brothers.

"My Muslim brothers have pointed out few scenes in my film which I'm ready to cut in order to settle the matter between us amicably," said Kamal.

Kamal, 58, described the ban as "cultural terrorism" and added: "Any neutral and patriotic Muslim will surely feel pride on seeing my film. It was designed for that purpose."

"Vishwaroopam" was also initially banned in places such as Karnataka, Kerala, Andhra Pradesh and Malayasia.

Written, produced and directed by Kamal, "Vishwaroopam" features him in the title role. Other members of the cast include Pooja Kumar, Andrea Jeremiah, Rahul Bose, Shekhar Kapur and Jaideep Ahlawat. Its Hindi version "Vishwaroop" is slated to release Friday.

Sex to burn calories? Authors expose obesity myths


Fact or fiction? Sex burns a lot of calories. Snacking or skipping breakfast is bad. School gym classes make a big difference in kids' weight.


All are myths or at least presumptions that may not be true, say researchers who reviewed the science behind some widely held obesity beliefs and found it lacking.


Their report in Thursday's New England Journal of Medicine says dogma and fallacies are detracting from real solutions to the nation's weight problems.


"The evidence is what matters," and many feel-good ideas repeated by well-meaning health experts just don't have it, said the lead author, David Allison, a biostatistician at the University of Alabama at Birmingham.


Independent researchers say the authors have some valid points. But many of the report's authors also have deep financial ties to food, beverage and weight-loss product makers — the disclosures take up half a page of fine print in the journal.


"It raises questions about what the purpose of this paper is" and whether it's aimed at promoting drugs, meal replacement products and bariatric surgery as solutions, said Marion Nestle, a New York University professor of nutrition and food studies.


"The big issues in weight loss are how you change the food environment in order for people to make healthy choices," such as limits on soda sizes and marketing junk food to children, she said. Some of the myths they cite are "straw men" issues, she said.


But some are pretty interesting.


Sex, for instance. Not that people do it to try to lose weight, but claims that it burns 100 to 300 calories are common, Allison said. Yet the only study that scientifically measured the energy output found that sex lasted six minutes on average — "disappointing, isn't it?" — and burned a mere 21 calories, about as much as walking, he said.


That's for a man. The study was done in 1984 and didn't measure the women's experience.


Among the other myths or assumptions the authors cite, based on their review of the most rigorous studies on each topic:


—Small changes in diet or exercise lead to large, long-term weight changes. Fact: The body adapts to changes, so small steps to cut calories don't have the same effect over time, studies suggest. At least one outside expert agrees with the authors that the "small changes" concept is based on an "oversimplified" 3,500-calorie rule, that adding or cutting that many calories alters weight by one pound.


—School gym classes have a big impact on kids' weight. Fact: Classes typically are not long, often or intense enough to make much difference.


—Losing a lot of weight quickly is worse than losing a little slowly over the long term. Fact: Although many dieters regain weight, those who lose a lot to start with often end up at a lower weight than people who drop more modest amounts.


—Snacking leads to weight gain. Fact: No high quality studies support that, the authors say.


—Regularly eating breakfast helps prevent obesity. Fact: Two studies found no effect on weight and one suggested that the effect depended on whether people were used to skipping breakfast or not.


—Setting overly ambitious goals leads to frustration and less weight loss. Fact: Some studies suggest people do better with high goals.


Some things may not have the strongest evidence for preventing obesity but are good for other reasons, such as breastfeeding and eating plenty of fruits and vegetables, the authors write. And exercise helps prevent a host of health problems regardless of whether it helps a person shed weight.


"I agree with most of the points" except the authors' conclusions that meal replacement products and diet drugs work for battling obesity, said Dr. David Ludwig, a prominent obesity research with Boston Children's Hospital who has no industry ties. Most weight-loss drugs sold over the last century had to be recalled because of serious side effects, so "there's much more evidence of failure than success," he said.
