Egypt protests set for showdown, violence feared

By Alastair Macdonald and Tom Perry

CAIRO (Reuters) - Mass demonstrations across Egypt on Sunday may determine its future, two and half years after people power toppled a dictator they called Pharaoh and ushered in a democracy crippled by bitter divisions.

The protesters' goal again is to unseat a president, this time their first freely elected leader, the Islamist Mohamed Mursi. Liberal leaders say nearly half the voting population - 22 million people - have signed a petition calling for change.

But with the long dominant, U.S-funded army waiting in the wings, and world powers fearing violence may unhinge an already troubled Middle East, Mursi's Muslim Brotherhood and militant allies pledge to defend what they say is the legitimate order.

Several people have been killed, including an American student, and hundreds were wounded in days of street fighting.

Mursi calls opponents bad losers backed by "thugs" from the rule of Hosni Mubarak. He is banking on the "Tamarud - Rebel!" coalition fizzling out, as other challenges in the streets have done since he took power a year ago on Sunday.

An economic crisis deepened by unrest and political deadlock may spur many less partisan Egyptians to join the rallies, due to start in the afternoon in Cairo. But many, too, are weary of turmoil and are skeptical that the opposition's demand to reset the rules of the new democracy is better than soldiering on.

U.S. President Barack Obama called on Egyptians to focus on dialogue. His ambassador to Egypt has angered the opposition by suggesting protests are not helping the economy.

Liberal leaders, fractious and defeated in a series of ballots last year, hope that by putting millions on the streets they can force Mursi to relent and hand over to a technocratic administration that can organize new elections.

"We all feel we're walking on a dead-end road and that the country will collapse," said Mohamed ElBaradei, former U.N. official, Nobel laureate and liberal party leader. "All Egypt must go out tomorrow to say we want to return to the ballot box, and build the foundations of the house we will all live in."

"CIVIL WAR"

Religious authorities have warned of "civil war". The army has said it will step in if violence gets out of control but insists it will respect the "will of the people".

Mursi, who on Saturday met the head of the military he appointed last year, interprets that to mean army support for election results. Opponents believe that the army may heed the popular will as expressed on the streets, as it did in early 2011 when the generals decided Mubarak's time was up.

That would depend on a massive turnout, which is uncertain. Islamists suspect that agents of the old order are intent on shedding blood to trigger a military intervention.

In Cairo, thousands of people gathered on Tahrir Square, the seat of the January 25 uprising of 2011, some saying they will camp out until Mursi goes. Others gathered outside the presidential palace several miles away, which was under heavy guard.

In a nearby suburban neighborhood, the Muslim Brotherhood and allies who include former militant organizations, have set up camp outside a mosque. Guarded by baton-wielding civilians in protective clothing, the Islamists say they will defend Mursi.

Both sides say they want to avoid violence but that has not prevented incidents in which the Brotherhood says several of its offices around the country have been attacked and at least five of its supporters killed in the past week.

"It will be imperative for peaceful protesters to clearly separate themselves from the thugs that use them as cover," an aide to Mursi said. "And it will be more important for the leaders calling for these protests to back away from the language of violence and demonization."

U.S. CONCERN

The United States has evacuated non-essential diplomatic staff and families and Obama said protecting U.S. missions was a priority. He was criticized at home when the ambassador to Libya was killed last year in an attack on the consulate in Benghazi.

The Egyptian army, half a million strong and financed by Washington since it backed a peace treaty with Israel three decades ago, says it has deployed to protect key installations.

Among these is the Suez Canal. Cities along the vital global waterway are bastions of anti-government sentiment. A bomb killed a protester in Port Said on Friday. Beyond the canal, in the Sinai peninsula which borders Israel and the Gaza Strip, a police general was gunned down in an ambush on Saturday.

Visiting the other end of Africa, Obama said in Pretoria: "Every party has to denounce violence ... We'd like to see the opposition and President Mursi engage in a more constructive conversation about how they move their country forward because nobody is benefiting from the current stalemate."

Mursi renewed an offer last week to include opponents in a new panel to review a controversial new constitution and has complained of a media campaign of vilification. The authorities have taken legal action against journalists and owners.

Opponents cite that among evidence that the Brotherhood, suppressed for decades under Mubarak, aims to use its organized, vote-winning power to entrench itself and its Islamic agenda deep in the state, in much the same way as the ousted leader.

Observers note similarities with protests in Turkey this month, where an Islamist prime minister with a strong electoral mandate has been confronted in the streets by angry secularists.

With much of the Arab world in turmoil after the uprisings that also brought sectarian civil war to Syria, the fate of its biggest nation may be determined by events in the coming days.

Daughter says Mandela "still there", raps media "vultures'

By Siphiwe Sibeko

PRETORIA (Reuters) - Former South African President Nelson Mandela is still clinging to life, his eldest daughter Makaziwe said on Thursday, but she criticised foreign media "vultures" for violating his privacy as he lay critically ill in hospital.

Makaziwe's outburst came as anxiety increased over the faltering health of the frail 94-year-old anti-apartheid hero, admired across the world as a symbol of resistance against injustice and of racial reconciliation.

Late on Wednesday, President Jacob Zuma's government reported a downturn in Mandela's condition after nearly three weeks of treatment in a Pretoria hospital for a lung infection.

This forced Zuma to cancel his participation in a regional summit in neighbouring Mozambique on Thursday.

But Zuma paid a second visit in 24 hours to Mandela on Thursday and was told by his doctors that he had improved overnight. "He remains critical but is now stable," presidency spokesman Mac Maharaj said in a statement.

"I won't lie, it doesn't look good," Mandela's daughter Makaziwe told state broadcaster SABC after visiting her father.

"But as I say, if we speak to him, he responds and tries to open his eyes. He's still there".

Accompanied by a group of grandchildren, she angrily criticised the "bad taste" of foreign media she said were intruding on the privacy of her father and his family.

"There's sort of a racist element with many of the foreign media, where they just cross boundaries," she said, after running the gauntlet of the pack of camera crews and reporters gathered outside the hospital.

"It's truly like vultures waiting when the lion has devoured the buffalo, waiting there for the last of the carcass. That's the image we have as a family," Makaziwe added.

Her criticism followed several sharp rebukes from Zuma's spokesman against some foreign media reports that have given alarming details of Mandela's deteriorating condition.

Maharaj declined to comment on the latest report by a major U.S. TV news network that South Africa's first black president was on life support. He said this was part of Mandela's confidential relationship with his doctors.

Daughter Makaziwe said: "If people say they really care about Nelson Mandela, then they should respect that. They should respect that there is a part of him that has to be respected."

She compared the massive media attention on Mandela, who has been in and out of hospital in the last few months with a recurring lung infection, with the coverage of the death in April of former British prime minister Margaret Thatcher.

"We don't mind the interest but I just feel it has gone overboard. When Margaret Thatcher was sick in hospital, I didn't see this kind of media frenzy around Margaret Thatcher," she said. "It is only God who knows when the time to go is."

OBAMA SAYS MANDELA "PERSONAL HERO"

Mandela's fourth hospitalisation in six months has forced a growing realisation among South Africans that the man regarded as the father of their post-apartheid "Rainbow Nation" will not be among them for ever.

"Mandela is very old and at that age, life is not good. I just pray that God takes him this time. He must go. He must rest," said Ida Mashego, a 60-year-old office cleaner in Johannesburg's Sandton financial district.

U.S. President Barack Obama, who is due to visit South Africa this weekend, said his thoughts and prayers were with the Mandela family and South Africans.

Speaking in Senegal, his first stop on a three-nation African tour, Obama said Mandela was a "personal hero" of his.

"Even if he passes on, his legacy will linger on," Obama said. He confirmed he still planned to travel to South Africa in the coming days, in response to speculation he might re-schedule his trip because of Mandela's deteriorating health.

Mandela is revered for his lifetime of opposition to the system of race-based apartheid rule imposed by the white minority government that sentenced him to 27 years in jail, more than half of them on the notorious Robben Island.

He is also respected for the way he preached reconciliation after the 1994 transition to multi-racial democracy following three centuries of white domination.

Well-wishers' messages, bouquets and stuffed animals have piled up outside Mandela's Johannesburg home and the wall of the hospital compound where he is being treated in the capital.

South Africans seemed resigned to the prospect of losing their hero, but expressed gratitude for what he had done.

"That great man who is in God's hands now fought so a black woman like me could move into this whites-only area in 1991," teacher Nthabi Chauke, 54, said outside the hospital. "Now I know what freedom feels like. I came here to say thank you."

Mandela stepped down in 1999 after one five-year term in office. Since then he has played little role in public life, dividing his time in retirement between his home in the wealthy Johannesburg suburb of Houghton and Qunu, the village in the impoverished Eastern Cape province where he was born.

3rd man held in Aaron Hernandez murder probe; Puma drops NFL star

Law enforcement officials have confirmed that Aaron Hernandez, who has been charged in the murder of Odin Lloyd, is also being investigated for two 2012 murders. NBC's Stephanie Gosk reports and NBC legal analyst Lisa Bloom discusses the revelations.

By Richard Esposito and Erin McClam, NBC News

A third man was in custody Friday in Florida in an expanding murder investigation swirling around Aaron Hernandez, the star NFL tight end accused of orchestrating the shooting death of a friend.

Massachusetts State Police

Ernest Wallace, 41, known as ?Fish,? turned himself in in the Miami suburb of Miramar, police said. Massachusetts police had said they were seeking him as an accessory after murder, and that he was considered armed and dangerous. They were on their way to Florida to pick him up, NBC affiliate WHDH in Boston reported.

Hernandez, an All-Pro who was released by the New England Patriots after his arrest earlier this week, is charged with first-degree murder in the execution of the friend, Odin Lloyd. He was denied a second request for bail Thursday.

Sources told NBC News that he was being investigated in another case ? the drive-by killings of two men in Boston last year. The men were shot to death in an SUV after leaving a nightclub.

Hernandez, who is being held in a Massachusetts jail, lost a second endorsement deal Thursday. The Puma sportswear company, which signed Hernandez to a two-year deal in April, told CNBC it was ending the relationship ?in light of the current situation.? CytoSport, maker of the Muscle Milk supplement drink, dropped Hernandez as a pitchman last week.

Authorities have said Hernandez took part in Lloyd?s killing in the early hours of June 17 after summoning two friends from out of state. Lloyd?s body was found in an industrial park near Hernandez?s home in North Attleborough, Mass. Hernandez has pleaded not guilty.

Connecticut authorities said Thursday that they had charged another man in connection with Lloyd?s killing ? Carlos Ortiz of Bristol, the city where Hernandez grew up. He was charged as a fugitive and agreed to return to Massachusetts, authorities said.

Authorities have not spelled out the connection they believe Wallace and Ortiz have to the killing. They have said Lloyd was killed by two shots fired from someone standing above him, but they have not said who they believe pulled the trigger.

Ortiz was being held on $1.5 million bail. His public defender declined comment on Thursday.

Prosecutors say that text messages ? including from Lloyd to his sister when he was worried about his safety ? and surveillance video are part of their case against Hernandez. The judge who denied his second request for bail, Renee Dupuis of Superior Court in Fall River, described the state?s case as ?circumstantial but very, very strong.?

Prosecutors said they had uncovered four new pieces of evidence in less than 24 hours after searching a condo leased by Hernandez. They said they had found ammunition, a clip and a picture of Hernandez with a Glock handgun.

William McCauley, an assistant district attorney, also said that Hernandez had interfered with the investigation by home surveillance-camera video and instructing his girlfriend not to talk to investigators.

?The evidence of his guilt is overwhelming,? prosecutor William McCauley said.

Hernandez?s lawyers argued that he deserved bail because of his upstanding character and clean record, and because he was not a risk to flee. They noted that he stayed put last week, when rumors circulated that Hernandez was about to be arrested.

(AP Photo/The Sun Chronicle, Mike George, Pool)

(AP) ? In the final minutes of his life, Odin Lloyd sent a series of texts to his sister.

"Did you see who I was with?" said the first, at 3:07 a.m. June 17. "Who?" she finally replied.

"NFL," he texted back, then added: "Just so you know."

It was 3:23 a.m. Moments later, Lloyd would be dead in what a prosecutor called an execution-style shooting orchestrated by New England Patriots tight end Aaron Hernandez because his friend talked to the wrong people at a nightclub. Hernandez was charged Wednesday with murder.

Hernandez was cut from the NFL team less than two hours after he was arrested and led from his North Attleborough home in handcuffs, and nine days after Lloyd's body was discovered by a jogger in a remote area of an industrial park not far from Hernandez's home. The 2011 Pro Bowl selection had signed a five-year contract last summer with the Patriots worth $40 million.

His attorney, Michael Fee, called the case circumstantial during a Wednesday afternoon court hearing packed with reporters, curiosity seekers and police officers. Fee said there was a "rather hysterical atmosphere" surrounding the case and urged the judge to disregard his client's celebrity status as he asked for Hernandez, 23, to be released on bail.

The judge, though, ordered Hernandez held without bail on the murder charge and five weapons counts. If convicted, Hernandez could get life in prison without parole.

Hernandez stood impassively with his hands cuffed in front of him as Bristol County Assistant District Attorney Bill McCauley laid out a detailed timeline of the events, cobbled together from sources including witnesses, surveillance video, text messages and data from cellphone towers.

Lloyd, 27, a semi-pro football player with the Boston Bandits, had known Hernandez for about a year and was dating the sister of Hernandez's fiancee, the mother of Hernandez's 8-month-old baby, McCauley said.

On June 14, Lloyd went with Hernandez to a Boston club, Rumor. McCauley said Hernandez was upset Lloyd had talked to people there with whom Hernandez had trouble. He did not elaborate.

Two days later, McCauley said, on June 16, Hernandez texted two unidentified friends. He asked them to hurry to Massachusetts from Connecticut. At 9:05 p.m., a few minutes after the first message to his friends, Hernandez texted Lloyd to tell him he wanted to get together, McCauley said.

Later, surveillance footage from Hernandez's home showed his friends arrive and go inside. Hernandez, holding a gun, then told someone in the house he was upset and couldn't trust anyone anymore, the prosecutor said.

At 1:12 a.m., the three left in Hernandez's rented silver Nissan Altima, McCauley said. Cell towers tracked their movements to a gas station off the highway. There, he said, Hernandez bought blue Bubblicious gum.

At 2:32 a.m., they arrived outside Lloyd's home in Boston and texted him that they were there. McCauley said Lloyd's sister saw him get into Hernandez's car.

From there, surveillance cameras captured images of what the prosecutor said was Hernandez driving the silver Altima through Boston. As they drove back toward North Attleborough, Hernandez told Lloyd he was upset about what happened at the club and didn't trust him, McCauley said. That was when Lloyd began sending texts to his sister.

Surveillance video showed the car entering the industrial park and at 3:23 a.m. driving down a gravel road near where Lloyd's body was found. Four minutes later, McCauley said, the car emerged. During that period, employees working an overnight shift nearby heard several gunshots, McCauley said.

McCauley said Lloyd was shot multiple times, including twice from above as he was lying on the ground. He said five .45 caliber casings were found at the scene.

Authorities did not say who fired the shots or identify the two others with Hernandez.

At 3:29 a.m., surveillance at Hernandez's house showed him arriving, McCauley said.

"The defendant was walking through the house with a gun in his hand. That's captured on video," he said.

His friend is also seen holding a gun, and neither weapon has been found, McCauley said.

Then, the surveillance system stopped recording, and footage was missing from the six to eight hours after the slaying, he said.

The afternoon of June 17, the prosecutor said, Hernandez returned the rental car, offering the attendant a piece of blue Bubblicious gum when he dropped it off. While cleaning the car, the attendant found a piece of blue Bubblicious gum and a shell casing, which he threw away. Police later searched the trash bin and found the gum and the casing. The prosecutor said it was tested and matched the casings found where Lloyd was killed.

As McCauley outlined the killing, Lloyd's family members cried and held each other. Two were so overcome that they had to leave the courtroom.

The Patriots said in a statement after Hernandez's arrest but before the murder charge was announced that cutting Hernandez was "the right thing to do."

"Words cannot express the disappointment we feel knowing that one of our players was arrested as a result of this investigation," it said.

Hernandez, originally from Bristol, Conn., was drafted by the Patriots in 2010 out of the University of Florida, where he was an All-American.

During the draft, one team said it wouldn't take him under any circumstances, and he was passed over by one club after another before New England picked him in the fourth round. Afterward, Hernandez said he had failed a drug test in college ? reportedly for marijuana ? and was up front with teams about it.

A Florida man filed a lawsuit last week claiming Hernandez shot him in the face after they argued at a strip club in February.

Hernandez became a father on Nov. 6 and said he intended to change his ways: "Now, another one is looking up to me. I can't just be young and reckless Aaron no more. I'm going to try to do the right things."

Lenovo IdeaPad S405


As a budget system, the Lenovo IdeaPad S405 comes with all the usual caveats: lower quality construction, fewer features, and good-enough hardware. That said, for an inexpensive laptop that will get you online and get you through your homework, the Lenovo IdeaPad S405 looks good, has passable performance, and does it all for an affordable price.

Design
The IdeaPad S405 looks sleek with a metallic finish, but it's superficial, with its 3.4 pound chassis made largely out of plastic. Measuring 0.83 by 13.2 by 9.5 inches (HWD), it is reasonably slim for a low-priced laptop, but the chassis flexes and bows noticeably whenever you pick up the laptop by the corner or type on the keyboard.

The 14-inch display offers standard 1,366-by-768 resolution, high enough for 720p video and side-by-side multitasking, but no support for full HD content. The TFT Color LCD display is best viewed head-on, as the viewing angles are quite narrow, and even when viewed at a slight angle?as one would when sharing a video with someone?I saw color distortion.

The keyboard, though made by Lenovo, doesn't feel as luxurious as on more expensive models, largely due to the all plastic construction. The keyboard flexes as you type, and the keys don't quite have the solid smooth feel experienced on other (pricier) IdeaPad laptops. That said, the sculpted keycaps and relatively smooth key movement is better than you'll get on most laptops in this price range.

The IdeaPad S405 is equipped with two-watt speakers and Dolby Advanced Audio v2, but sound quality was good, not great. When testing the bass with Silent Shout by the Knife, you could hear the bass, but it was empty. When testing treble and volume with Jimi Hendrix's Bold as Love instrumental, the speakers initially produced clear sound sound, but the clarity dropped off the higher the volume went. At full volume, there's enough oomph to fill a large room, but you won't be able to ignore the buzz that comes with it.

Features
The IdeaPad S405 is outfitted with a modest collection of ports, with two USB 2.0 ports, one USB 3.0 port, an HDMI port, SD card slot, and a compact Ethernet port. While you also have 802.11n Wi-Fi, you won't find Bluetooth?that's one of the compromises you'll make for the lower price. Lenovo also has built in its OneKey Recovery, which gives you a single button to restore your system in the event of a crash or other problem.

The IdeaPad S405 features a 500GB, 5,400 rpm hard drive, which isn't particularly large, but is a common size in value-priced systems. You won't have all 500GB available out of the box, however, with space being occupied by the operating system?Windows 8 (64-bit)?a recovery partition, and several preinstalled programs. On the start screen you'll find several apps, like AccuWeather, Kindle Reader, Rara Music, Evernote, and a 60-day trial of Microsoft Office 2013. Dig in further on the desktop side and you'll also find McAfee Internet Security, Lenovo Cloud Storage (with SugarSync), and Nitro Pro PDF reader. Lenovo covers the IdeaPad S405 with a one-year limited warranty on parts and labor.

Performance
Lenovo IdeaPad S405 The Lenovo IdeaPad S405 uses a 2.1GHz AMD A6-4455M APU paired with 4GB of RAM. AMD uses a slightly different take on the CPU, which AMD calls the APU, which puts the processor and the accompanying graphics processor?an AMD Radeon HD 7500G?on the same chip die. This isn't the newest processor to begin with (this same processor was actually used in the HP Envy Sleekbook 6z-1000 last August), and when stacked against the Intel Core processors used in competing systems, like the Acer Aspire V5-571-6891 and Toshiba Satellite C875-S7340, it has a tough time keeping up. In Cinebench, the IdeaPad S405 scored 0.79 points, falling far behind the Acer V5-571-6891 (1.80 points) and Toshiba C875-S7340 (2.41 points). Even the similarly-equipped HP Envy Sleekbook 6z-1000 pulled ahead (0.87 points).

Lenovo IdeaPad S405

This performance gap was made all the more obvious in our Handbrake and Photoshop tests, which the IdeaPad S405 crawled through in 4 minutes 14 seconds and 11:33, respectively. By comparison the Lenovo G580 completed those same tasks in less than half the time (1:18 Handbrake; 5:32 Photoshop), and the Toshiba C875-S7340 wasn't far behind (1:28 Handbrake; 5:47 Photoshop). The IdeaPad S405 will be fine for light productivity and Web browsing, but it will slow down dramatically in any processor intensive application.

Despite the inclusion of the AMD Radeon HD 7500G graphics processor, the IdeaPad S405 had somewhat limited graphics capability. Though sufficient for Web browsing and video playback, gaming performance will be limited to online and casual games, not the high-performance games often associated with a discrete graphics card.

The IdeaPad S405's 4-cell lithium-ion battery did reasonably well in our battery rundown test, lasting 4 hours 7 minutes, identical to the class-leading Acer V5-571-6891 (4:07). This is actually one area where the IdeaPad S405 outperformed its rivals, with the Toshiba C875-S7340 lasting a mere 2:39.

Conclusion
Some value-priced laptops offer more than simple affordability, with features and components that belie the budget-friendly price. While these systems may cut corners with wobbly construction or a trimmed down feature set, they do so while still delivering adequate performance. The Lenovo IdeaPad S405 is definitely affordable, but it comes with too many shortcomings to recommend?the sluggish performance and limited capability are too much to give up for the price. For a similar price without the compromises, we recommend the Editors' Choice Lenovo G580.

Op-Ed: Arts Education Is Critical to Student Success

Have you ever wondered what the world would look like if there were no artists? You would not have clothes, furniture, jewelry, electronics, transportation, cell phones, buildings, toys, or websites. The list goes on and on, yet art is often absent from our daily thoughts.

I teach a commercial art class. Last year I had a mother who took her daughter out of my class. She thanked me for teaching her daughter a nice hobby, but she wanted her to be able to get a real job.

Many people do not understand that art is a crucial component to a well-rounded education. Art education develops critical thinking, problem-solving and hand-eye coordination. It provides a vehicle to explore the possibilities and limitations of materials, and encourages children to use their imaginations. It is an outlet that lets children express how they feel, think, and view the world in ways they may not be able to say with words.


Visual arts teaches students that problems can have more than one solution, and questions can have more than one answer. Unlike academic curriculums in which correct answers and rules prevail, art is based on observational judgment rather than a scantron.

The National Art Education Association published the report?Learning in a Visual Age: The Critical Importance of Visual Arts Education. It states, ?Art education opens the possibility for creating new worlds, rather than simply accepting the world as it is?students learn a great deal in high-quality visual arts classes that is not captured on standardized tests? teaching students to be creative is a deliberate process, much like teaching students to be literate or to be able to solve mathematics problems.?

Years of research show that art education stimulates and develops the imagination and critical thinking, and refines cognitive and creative skills.


Many people in academia, and the business world, still may think that art is a cute hobby for old ladies and not see it as benefiting other subjects. As an art teacher, I know and have seen how art benefits my students. In one art lesson, I can teach mathematics, language arts, history, and world culture before any student picks up a paintbrush. I tell my students that drawing and painting is easy; it is developing the thought process that is challenging.

Many people know of Da Vinci?s famous Mona Lisa?or The Last Supper, but they don?t know that he was also an architect, engineer, and a scientist.? Think about what inspired Da Vinci?s inventions and how he translated them through his artwork.

A blog post on Psychology Today raised a question about the benefits of the arts in other subjects: ?Let?s see what happens when we start throwing out all the science and technology that the arts have made possible. The fact is that the arts foster innovation?almost all Nobel laureates in the sciences actively engage in arts.?

Art education has many obstacles to overcome, not the least of which is how it?s devalued by often not being required for graduation.?It will continue to face these challenges until it becomes a necessary part of school curriculum.?

Chicken in Teen Diet May Ward Off Colon Cancer

Eating chicken during high school may reduce the risk of a precancerous condition that may develop into colon cancer, a new study finds.

In a study of nearly 20,000 women, those who ate more chicken during their teen years had lower risks of developing colorectal adenomas, which are benign tumors that may progress into colon cancer.

The researchers didn't find a direct relationship between red meat intake and adenomas, but the results showed that replacing one serving per day of red meat with one serving of poultry or fish may reduce the risks of rectal and advanced adenomas by about 40 percent.

"Among different cancers, colorectal cancer is the most influenced by diet," said study researcher Dr. Katharina Nimptsch. "Compared to something like smoking, diet is not a large cancer risk factor, but it does have an impact."

Previous research has found that a diet high in red and processed meat may increase risks of colon cancer. Other risk factors for developing colon cancer include heavy alcohol consumption, lack of exercise, as well as diabetes and a diet rich in fat.

However, previous studies have investigated diet during adulthood, rather than focusing on what people eat earlier in life, and their future cancer risk.

"Colorectal carcinogenesis is a long process that can take several decades, and the initial steps of carcinogenesis may occur at young ages," the researchers wrote in their study.

In the study, 19,771 women ages 34 to 51 answered questions about their diet during high school. Over the following 10 years, 1,494 of the women were diagnosed with colorectal adenomas. Of these adenomas, 305 were in an advanced stage.

"Our findings do not suggest an association between red meat intake during adolescence and colorectal adenomas later in life, but higher poultry intake during this time was associated with a lower risk of colorectal adenomas," the researchers said.

Eating more poultry and fish in adulthood didn't seem to change the risk, according to the study.

The researchers found it surprising that the results didn't show a link between red meat and the risk of adenomas, Nimptsch said. "When you look at the amount of meat people ate, it was really high." However, there were few women in the study who ate very little red meat; perhaps there was not enough variation to see a significant difference in risk, she said.

As with other observational studies, the findings cannot show a cause-and-effect relationship. "Before recommendations are made based on these findings, it is necessary that results are confirmed," Nimptsch said.

The results add to previous evidence that eating poultry may decrease risk of colon cancer. However, what mechanism might underlie the link remains unclear.

The study was published June 19 in the American Journal of Epidemiology.

Russia defiant over NSA leaker

By Lidia Kelly and James Pomfret

MOSCOW/HONG KONG (Reuters) - Russia defied White House pressure on Monday to expel former U.S. spy agency contractor Edward Snowden to the United States before he flees Moscow on the next stop of his globe-crossing escape from U.S. prosecution.

Snowden, whose exposure of secret U.S. government surveillance raised questions about intrusions into private lives, was allowed to leave Hong Kong on Sunday after Washington asked the Chinese territory to arrest him on espionage charges.

The 30-year-old flew to Moscow as a transit stop before heading elsewhere, several sources said. But reports he would fly to Cuba were put in doubt when witnesses could not see him on the plane, despite heightened security before take-off.

Ecuador, which has sheltered the founder of the WikiLeaks anti-secrecy organization, Julian Assange, said it was considering Snowden's request for asylum. There is no direct flight to Quito from Moscow.

"He didn't take the flight (to Havana)," a source at Russia's national airline Aeroflot told Reuters.

As speculation mounted about where he would go next - Ecuador, Venezuela or Havana at a later date to escape the crowd of journalists on board Monday's flight - Washington was stung by Russian defiance.

Snowden's flight to Russia, which like China challenges U.S. dominance of global diplomacy, is an embarrassment to President Barack Obama who has tried to "reset" ties with Moscow and build a partnership with Beijing.

The White House said it expected the Russian government to send Snowden back to the United States and lodged "strong objections" to Hong Kong and China for letting him go.

But the Russian government ignored the appeal and President Vladimir Putin's press secretary denied any knowledge of Snowden's movements.

Asked if Snowden had spoken to the Russian authorities, Peskov said: "Overall, we have no information about him."

He declined comment on the expulsion request but other Russian officials said Moscow had no obligation to cooperate with Washington, after it passed legislation to impose visa bans and asset freezes on Russians accused of violating human rights.

U.S. HYPOCRISY

"Why should the United States expect restraint and understanding from Russia?" said Alexei Pushkov, the head of the foreign affairs committee in the lower house of parliament.

Putin has missed few chances to champion public figures who challenge Western governments and to portray Washington as an overzealous global policeman. But Russian leaders have not paraded Snowden before the cameras or trumpeted his arrival.

Since leaving Hong Kong, where he feared arrest and extradition, Snowden has been searching for a country that can guarantee his security.

Ecuadorean Foreign Minister Ricardo Patino, on a trip to Vietnam, said Quito would analyze his asylum request with a "lot of responsibility". He was expected to hold a news conference around 7 p.m. (1200 GMT) in Hanoi.

A source at Aeroflot said on Sunday Snowden was booked on the flight due to depart for Havana on Monday at 2:05 p.m. (1005 GMT). But a correspondent aboard could not see him and the seat he was supposed to occupy, 17a, was taken by another passenger.

A State Department official said Washington had told countries in the Western Hemisphere that Snowden "should not be allowed to proceed in any further international travel, other than is necessary to return him to the United States".

Despite the Kremlin denials, U.S. Senator Charles Schumer said Putin had probably known about and approved Snowden's flight to Russia.

"Putin always seems almost eager to stick a finger in the eye of the United States," Schumer, a senior Senate Democrat, told CNN's "State of the Union". He also saw "the hand of Beijing" in Hong Kong's decision to let Snowden leave.

But taking the higher ground after being accused of hacking computers abroad, the Chinese Foreign Ministry expressed "grave concern" over Snowden's allegations that the United States had hacked computers in China.

It said it had taken up the issue with Washington.

CHILL

Some Russians have praised Snowden's revelations. Others fear a new chill in relations with the United States.

"We are a pretty stubborn country and so is the United States. Both are mighty countries, so I would say this has a good potential to turn into a big fuss in bilateral relations," said Ina Sosna, manager of a Moscow cleaning company.

"I guess it would be best if they just let him move on from Russia to avoid any more controversy over him being here."

Snowden was assisted in his escape by WikiLeaks, whose founder Assange said he had helped to arrange documents from Ecuador.

Ecuador, like Cuba and Venezuela, is a member of the ALBA bloc, an alliance of leftist governments in Latin America that pride themselves on their "anti-imperialist" credentials. The Quito government has been sheltering Assange at its London embassy for the past year.

The New York Times quoted Assange as saying in an interview that his group had arranged for Snowden to travel on a "special refugee document" issued by Ecuador last Monday.

U.S. sources said Washington had revoked Snowden's passport. WikiLeaks said diplomats and Sarah Harrison, a British legal researcher working for the anti-secrecy group, accompanied him.

Snowden, who had worked at a U.S. National Security Agency facility in Hawaii, had been hiding in Hong Kong, a former British colony that returned to China in 1997, since leaking details about secret U.S. surveillance programs to news media.

Snowden has been charged with theft of federal government property, unauthorized communication of national defense information and willful communication of classified communications intelligence to an unauthorized person, with the latter two charges falling under the U.S. Espionage Act.

Snowden's stealthy exit: How WikiLeaks and maybe Russia helped

The NSA leaker is traveling to Moscow en route to a third country. Russian President Vladimir Putin's spokesman told journalists Sunday that he knows nothing of Snowden's travel plans.

Mr. Snowden left his temporary refuge in Hong Kong?Sunday?morning, just one day after the US government charged him with espionage and launched an urgent effort to extradite him from the former British colony. He boarded an Aeroflot flight to Moscow, and news reports say he has an onward ticket with the Russian national airline to fly to Cuba?on Monday.

In addition to the clear suggestion of official Russian aid with the fleeing whistleblower's logistics, Snowden appears to have received help from a more kindred source. WikiLeaks tweeted?Sunday?that it had "assisted Mr. Snowden's political asylum in a democratic country, travel papers and safe exit from Hong Kong."

Kremlin authorities earlier hinted that Russia might be willing to grant asylum to Snowden. But President Vladimir Putin's spokesman, Dmitry Peskov, told journalists?Sunday?that he knows nothing about the NSA leaker's travel plans.

Authorities in Hong Kong announced Snowden's departure?Sunday?in an official statement?that noted he had left "on his own accord for a third country through a lawful and normal channel," and added that US authorities had already been informed.

The statement said the urgent US warrant to arrest Snowden could not be carried out "since the documents provided by the US Government did not fully comply with the legal requirements under Hong Kong law.... ?As the HKSAR [Hong Kong] Government has yet to have sufficient information to process the request for provisional warrant of arrest, there is no legal basis to restrict Mr Snowden from leaving Hong Kong."

The statement included an extraordinary passage that may go far toward explaining why Hong Kong, which does have an extradition treaty and good relations with the US, appears to have turned so uncooperative in Snowden's case: "Meanwhile, the HKSAR Government has formally written to the US Government requesting clarification on earlier reports about the hacking of computer systems in Hong Kong by US government agencies. The HKSAR Government will continue to follow up on the matter so as to protect the legal rights of the people of Hong Kong."

Wikileaks founder Julian Assange said in a statement?Sunday?that his organization was providing legal and logistical help to move Snowden to a safe haven in a "democratic country."

"Mr. Snowden is flying in an Aeroflot aircraft over Russian airspace, accompanied by WikiLeaks legal advisers," Mr. Assange said.

Upon arrival in Moscow he will be "met by diplomats from the country that will be his ultimate destination. Diplomats from that country will accompany him on a further flight to his destination," he added. The third country is still not named, but experts say it's most likely to be Venezuela or Ecuador.

"Owing to WikiLeaks' own circumstances, we have developed significant expertise in international asylum and extradition law, associated diplomacy and the practicalities in these matters," Assange said.?"I have great personal sympathy for Ed Snowden's position. WikiLeaks absolutely supports his decision to blow the whistle on the mass surveillance of the world's population by the US government."

Snowden's latest revelations, published in Hong Kong's South China Morning Post?on Sunday, indicate that US intelligence agencies have been hacking Chinese mobile phone companies to steal millions of text messages.

Russian security expert Andrei Soldatov, who edits Agentura.ru, an online journal that focuses on the secret services, says that in addition to granting Snowden safe passage to Cuba on an Aeroflot jetliner, Russia may have played a deeper role in helping to arrange his flight.

He suggests that the Kremlin's English-language satellite news network, RT, which enjoys very close relations with WikiLeaks founder Julian Assange, could have used its offices to help Wikileaks hook up with Snowden in Hong Kong,?

"There are reports that Assange's assistant, Sarah Harrison, is flying on the same plane with Snowden," says Mr. Soldatov.?"Involvement of RT would make sense, since RT has close cooperation with Assange, and he did a series of programs for them last year [Russia gives WikiLeaks' Julian Assange a TV platform]. The involvement of WikiLeaks requires no explanation. It wants to maintain itself as the key center for all disclosures of the kind that Snowden brought to the world," he adds.?

Soldatov says Russian assistance is also logical, for wider reasons than just an opportunity to stick it to Uncle Sam.

"Russia and China have been involved in a so-far unsuccessful struggle to change the rules of the Internet, by taking control of it away from the US-based Internet Corporation for Assigned Names and Numbers (ICANN) and giving its functions to a wider, non-US-based entity," he says.

"The Russians and Chinese have been posing, for these purposes, as big defenders of Internet freedom. This political context helps to explain RT's close relations with WikiLeaks as well.... So, it makes sense for them to help Snowden too. Russian authorities see an opportunity to present themselves as the new center of refuge for whistleblowers against US dominance in Cyberspace. It's a coup for them," he adds.??

Iranian expectations soar after Rohani's election

As Iranians erupted in celebration over the victory of Hassan Rohani, they knew what they wanted from their president-elect: more social freedoms, a better economy, and less ?resistance? to the rest of the world.

The centrist cleric has promised them as much. But Iranian politics are an unruly tangle in which moderate agendas have often been wrecked by hard-line factions. Will Mr. Rohani be able to bring change without upending the Islamic Republic? Has this regime insider ? who declared in 1999 that student protesters ?would be punished as corrupt on earth who waged war on God? ? learned lessons from those chaotic days and those of the 2009 Green Movement protests? And will he have the mettle to achieve the promised transformation?

?It will be challenging for Rohani to make changes. People need to be more patient; they cannot expect to see immediate results,? says Azadeh, an engineer and mother in central Tehran who asked that only her first name be used. ?It?s not just up to the president. But because he is a strong personality and has a lot of support from influential politicians, he can succeed.?

Rohani was able to defeat the five conservative candidates in a surprise first-round win because of endorsements from two reformist former presidents: Mohammad Khatami, who won landslide victories in 1997 and 2001 on promises of change, and Akbar Hashemi Rafsanjani.

Their support ? and their apparent faith in an electoral process that many Iranians had given up on after the fraud-tainted 2009 vote ? swept Rohani to what he called a ?victory of wisdom and moderation? over extremism, although he remains close to supreme leader Ayatollah Ali Khamenei.

?People want more freedom and civil rights and economic prosperity,? says a bearded musician in Tehran who plays classical Persian music. ?I think that even with the factions within the establishment, Rohani will be able to fulfill his promises because the [ruling system?s] goal right now is to calm society.?

MIXED RECORD

Even though Rohani took an uncompromising line against pro-democracy protesters in 1999, his own children are believed to have links to the opposition Green Movement activities, as do the offspring of many senior officials.

Rohani never spoke out about the protest and crackdown in 2009, but he says he will work to release Green Movement leaders and former presidential candidates Mir Hossein Mousavi and Mehdi Karroubi from house arrest.

?In the suppression of the Green Movement, Rohani did not stand up for protesters,? notes Azadeh. ?Maybe it was his tactic to save face to become a presidential candidate. But let?s see what he does in the future.?

Those events were a learning experience for Rohani and to a degree Mr. Khamenei, reflected in his call just days before the election for those ?who don?t want to back Islamic system? to vote anyway, for the nation.

Rohani has promised a ?civil rights charter? and has spoken frequently about broader political and social rights and less government interference in people?s lives. The conservative establishment has lined up to praise his victory, and police have clearly been ordered not to prevent street celebrations.

?These are signs of wisdom, that they have learned from the previous mistakes,? says an Iranian analyst in Tehran. ?There is this strange capability of the Islamic regime for survival. Under tremendous pressures they get very close to the precipice, and something happens and they turn back ... to avoid very, very big disasters.?

?I don?t think Hassan Rohani is faking it,? says the analyst. ?The question is, will he make it? Will he be allowed ? or will he be able ? to have room enough to do that??

BALANCING ACT

The answer may depend on how Rohani balances competing pressures. He knows many Revolutionary Guard commanders from his role managing the 1980s Iran-Iraq War, but he is also close to figures like Mr. Rafsanjani, who were pilloried by hard-liners for fomenting the 2009 ?sedition? that shook the regime to the core.

?There has always been some apprehension about [Rohani] in the security and intelligence establishment, about his hard-line credentials being insufficient on national security,? says an Iranian political scientist in Washington. ?So he?s going to have some problems with those guys, no matter what.?

His tough approach to the 1999 student uprising came amid fear of ?chaos and a real collapse of the system,? says the academic. ?That position does not necessarily repudiate the overall moderate orientation [today]. The time was different, and of course [Rohani] has grown and changed.?

As for chances of a resurgence of the vigilante groups that were active during the Khatami era, and deployed in the 2009 crackdown?

?There is a growing sense among even hardcore conservatives that those tactics are no longer paying off or could be deployed,? says the political scientist. ?I?m not ruling out the possibility of those vigilantes regrouping and starting again; that depends very much on how Rohani reacts and how Rohani plays the game.?

The Monitor correspondent and sources have been left unnamed for security reasons.

Bristol Community College plans Taunton expansion

Bristol Community College plans to begin offering daytime classes in Taunton this fall.

The Taunton School Committee voted 7-1 Wednesday to allow Superintendent Julie Hackett?s administration to move forward with a plan to allow BCC to use space at the Cohannet School building.

?Taunton has a critical need for access to higher education in the city,? BCC President John J. Sbrega said. ?Taunton has always been an important part of our service area, and while we have provided direct services in the evening, it is clear from city officials and business leaders that there are residents who can benefit from college courses during the day. We are happy to serve those students.?

The community college plans to offer daytime general education courses in English, math, history and behavioral sciences at Cohannet in the fall. The credits from the courses will be able to be applied to any degree or certificate program, according to the college. Developmental courses will also be offered for students who need to improve their skills before doing college-level coursework.

?This is the start of bringing an institution of higher learning to downtown for all the citizens of Taunton,? School Committee member David Souza said.

The news comes just two weeks after Boston-based Bay State College got approval to relocate its Middleboro satellite to Myles Standish Industrial Park in Taunton.

BCC has a main campus in Fall River and satellites in New Bedford and Attleboro. The community college currently offers evening courses in Taunton at Friedman Middle School.

Cohannet, which was originally a middle school then served as the temporary home of Taunton District Court, currently houses Taunton?s alternative high school.

?We haven?t worked out any details,? Hackett said. ?What we would be talking about for a September start date would be a couple courses at a time. We?d have a small impact to begin with, then see how it goes.?

Josephine Almeida, who cast the lone vote opposing the plan to bring BCC to Cohannet in the fall, raised concerns about community college students and alternative high school students being in the building at the same time. She also said she thinks Cohannet School should be the future home of the superintendent?s office and central administration.

?I think BCC is a wonderful program, however, I don?t think September is the time to start it at Cohannet,? Almeida said.

Almeida complained that the School Committee hasn?t been given time to thoroughly discuss the proposal.

?There?s an old adage that you strike while the iron is hot. As far as I?m concerned the iron is hot right now,? Christine Fagan said. ?We should seize the opportunity here. It doesn?t come around very often that a high school can partner with a community college of BCC?s stature.?

Preliminary plans call for the a total of four classes to be offered, no more than two at any given time in the day. The classes, Hackett said, would end in the morning before the alternative high school?s day begins.

Sbrega credited state Sen. Marc Pacheco, D-Taunton, Mayor Thomas Hoye Jr. and Hackett for working to help launch the BCC day program.

?It?s going to be a tremendous shot in the arm for Taunton?s economic development and a great opportunity for students who may not have enjoyed those opportunities,? he said.

According to BCC?s enrollment data, approximately 10 percent of its 12,000 students are from the Greater Taunton area. Sbrega expects to see that number spike once day classes are established in the city, mirroring a trend he saw when the community college established programs in New Bedford and Attleboro.

?This is a great partnership with the city and with Bristol Community College, and it?s a great opportunity for our students,? Hackett said.

Efficient and inexpensive: Researchers develop catalyst material for fuel cells

June 17, 2013 ? Efficient, robust and economic catalyst materials hold the key to achieving a breakthrough in fuel cell technology. Scientists from J?lich and Berlin have developed a material for converting hydrogen and oxygen to water using a tenth of the typical amount of platinum that was previously required. With the aid of state-of-the-art electron microscopy, the researchers discovered that the function of the nanometre-scale catalyst particles is decisively determined by their geometric shape and atomic structure. This discovery opens up new paths for further improving catalysts for energy conversion and storage.

The results have been published in the current issue of the journal Nature Materials.

Hydrogen-powered fuel cells are regarded as a clean alternative to conventional combustion engines, as, aside from electric energy, the only substance produced during operation is water. At present, the implementation of hydrogen fuel cells is being hindered by the high material costs of platinum. Large quantities of the expensive noble metal are still required for the electrodes in the fuel cells at which the chemical conversion processes take place. Without the catalytic effect of the platinum, it is not currently possible to achieve the necessary conversion rates.

As catalysis takes place at the surface of the platinum only, material can be saved and, simultaneously, the efficiency of the electrodes improved by using platinum nanoparticles, thus increasing the ratio of platinum surface to material required. Although the tiny particles are around ten thousand times smaller than the diameter of a human hair, the surface area of a kilogram of such particles is equivalent to that of several football fields.

Still more platinum can be saved by mixing it with other, less valuable metals, such as nickel or copper. Scientists from Forschungszentrum J?lich and Technische Universit?t Berlin have succeeded in developing efficient metallic catalyst particles for converting hydrogen and oxygen to water using only a tenth of the typical amount of platinum that was previously required.

The new catalyst consists not of the round nanoparticles that were previously in widespread use, but of octrahedral-shaped nanoparticles of a platinum-nickel alloy. The researchers discovered that the unique manner in which the platinum and nickel atoms arrange themselves on the surfaces of these particles serves to optimally accelerate the chemical reaction between hydrogen and oxygen to form water. Round or cubic particles, on the other hand, have different atomic arrangements at the surface and are therefore less effective catalysts for the chemical reaction, something which would have to be compensated by using increased amounts of noble metal.

The way in which the life-cycle of the catalysts depends on and can be optimized by their atomic composition was the subject of the research team's investigation, which made use of ultrahigh-resolution electron microscopy at the Ernst Ruska-Centre (ER-C), a facility of the J?lich Aachen Research Alliance. "A decisive factor for understanding the life-cycle of the catalysts was the observation that nickel and platinum atoms prefer not to be evenly distributed at the surface of the nano-octahedra," explains Dr. Marc Heggen from ER-C and the Peter Gr?nberg Institute at Forschungszentrum J?lich. "Although this is advantageous for reactivity, it limits lifetime."

To identify the location of each element with atomic precision, the researchers used a method in which the electron beam of one of the world's leading ultrahigh-resolution electron microscopes is finely focused, sent through the specimen and, by interactions with the specimen, loses part of its energy. Each element in the specimen can thus be identified like a fingerprint. Conventional electron microscopes are not capable of detecting such chemical signatures with atomic resolution.

"This pioneering experimental work provides direct evidence for the fact that the choice of the correct geometric shape for the catalyst particles is as important for optimizing their function as the choice of their composition and size," says Prof. Peter Strasser from Technische Universit?t Berlin. "This provides researchers with new possibilities for further improving functional materials, especially catalysts, for energy storage." The latest experiments from Strasser's research group indicate that substantial increases in efficiency may also be possible for the reaction splitting water to produce oxygen in electrolysers, for which the even more expensive noble metal iridium is used.
