B Vitamins May Reduce Risk of Colorectal Cancer

Involving a total of 88,045 postmenopausal women who were recruited between 1993 and 1998; The Women's Health Initiative Observational Study covers the time period in which the United States introduced mandatory fortification of grain products with folic acid (a bioavailable form of folate).? Stefanie Zschabitz, from Fred Hutchinson Cancer Research Center (Washington, USA), and colleagues analyzed the diagnosis of 1,003 incident colorectal cancer cases in the study group that were ascertained as of 2009. The researchers observed that women with the highest average intakes of riboflavin (vitamin B2, over 3.97 mg per day) were at a 20% lower risk of colorectal cancer (as compared to women with the lowers average intakes at less than 1.8 mg).? Additionally, the highest intakes of pyridoxine (Vitamin B6, over 3.88 mg per day) were found to lower the risk by 20%? (as compared to women with the lowers average intakes at less than 1.52 mg).? The study authors conclude that: ?Vitamin B-6 and riboflavin intakes from diet and supplements were associated with a decreased risk of [colorectal cancer] in postmenopausal women.?

A bounce-house addition to the International Space Station?

NASA and Bigelow Aerospace plan to add a $17.8 million inflatable room to the International Space Station. The Bigelow Expandable Activity Module, or BEAM, will house astronauts, and is built to withstand heat, radiation, debris and other assaults.

NASA is partnering with a commercial space company in a bid to replace the cumbersome "metal cans" that now serve as astronauts' homes in space with inflatable bounce-house-like habitats that can be deployed on the cheap.

A $17.8 million test project will send to the International Space Station an inflatable room that can be compressed into a 7-foot tube for delivery, officials said Wednesday in a news conference at North Las Vegas-based Bigelow Aerospace.

If the module proves durable during two years at the space station, it could open the door to habitats on the moon and missions to Mars, NASA engineer Glen Miller said.

The agency chose Bigelow for the contract because it was the only company working on inflatable technology, said NASA Deputy Administrator Lori Garver.

Founder and President Robert Bigelow, who made his fortune in the hotel industry before getting into the space business in 1999, framed the gambit as an out-of-this-world real estate venture. He hopes to sell his spare tire habitats to scientific companies and wealthy adventurers looking for space hotels.

NASA is expected to install the 13-foot, blimp-like module in a space station port by 2015. Bigelow plans to begin selling stand-alone space homes the next year.

The new technology provides three times as much room as the existing aluminum models, and is also easier and less costly to build, Miller said.

Artist renderings of the module resemble a tinfoil clown nose grafted onto the main station. It is hardly big enough to be called a room. Miller described it as a large closet with padded white walls and gear and gizmos strung from two central beams.

Garver said Wednesday that sending a small inflatable tube into space will be dramatically cheaper than launching a full-sized module.

"Let's face it; the most expensive aspect of taking things in space is the launch," she said. "So the magnitude of importance of this for NASA really can't be overstated."

The partnership is another step toward outsourcing for NASA, which no longer enjoys the budget and public profile of its heyday. The agency has handed off rocket-building to private companies, retired it space shuttles in 2011 and now relies on Russian spaceships to transport American astronauts to and from the space station.

Astronauts will test the ability of the bladder, known as the Bigelow Expandable Activity Module, or BEAM, to withstand heat, radiation, debris and other assaults. Some adventurous scientists might also try sleeping in the spare room, which is the first piece of private real estate to be blasted into space, Garver said.

Bigelow said the NASA brand will enable him to begin selling Kevlar habitats several times the size of the test module.

"This year is probably going to be our kickoff year for talking to customers," he said. "We have to show that we can execute what we're talking about."

Bigelow, who launched a small prototype of the module in 2006 after licensing the patent from NASA, will rely on Boeing Co. and Southern California rocket developer Space Exploration Technologies to provide transportation.

A 60-day stay will cost $25 million, which doesn't include the $27.5 million it costs to get there and back.

Bigelow predicted that the primary customers will be upwardly mobile countries including Brazil, Singapore and the United Arab Emirates that "have a difficult time getting their astronauts into orbit" and could use a private space station to barter and build up prestige.

The biggest technological challenge will be transporting the collapsed module through the sub-zero temperatures of space without tearing or cracking any part of it, Miller said.

When it arrives at the space station in 2015, scientists will blow it up and let it sit for a few days to test for leaks. If it does not hold as promised, NASA will take back a portion of the already bargain basement price it paid Bigelow.

Standing beside scale models of research stations on Mars and the moon, Miller said the project will encourage commercial ventures to follow the path NASA blazes into space.

He added that it could also help achieve the holy grail of space exploration: missions that send astronauts out of orbit for more than a year.

"The only way to do that is to expand it out and voila you have living space for three people to go to Mars," he said. "You can get three times the volume of a metallic can, and you can go up in the same ferry."

Quinton ?Rampage? Jackson is so over the UFC

Quinton "Rampage" Jackson will fight Glover Teixiera at UFC on Fox 6. If Jackson stays true to his word, it will be his last fight in the UFC. He has complained about being a part of the UFC time and time again. He reiterated on a pre-fight press call that he is done, done, done with the UFC. This is the last fight of his contract, and he has no plans to renegotiate with them.

"I think the UFC don't know how to treat the athletes, in my opinion," he said. "I feel like the fighters do a lot for the sport and I feel like we're not taken care of well enough. I feel like they're getting rich off all of us."

His cries are starting to sound like the lyrics to a Taylor Swift song. Jackson and the UFC are never ever ever getting back together. But if he doesn't fight for the UFC, his options for high-level MMA are limited. He said he could try other combat sports like kickboxing or boxing. Bellator could be an option, but one of Jackson's beefs with the UFC has been their matchmaking. The tournament set-up could be tough for him to deal with.

Either way, enjoy Jackson in the UFC while you can, because it's over for real this time.

VATICAN CITY (AP) ? U.S. Defense Secretary Leon Panetta, the leader of the world's largest military, met Pope Benedict XVI, the world's best known advocate for peace, at the Vatican on Wednesday.

Panetta was in the front row at Wednesday's weekly general audience in the Vatican auditorium. About 1,000 people were crowded into the room.

After the Pope addressed the gathering, Panetta and several staff members lined up to meet the pontiff, who gave them rosaries.

Panetta kissed the Pope's hand, and the Pope said, "Thank you for helping to protect the world."

The Pentagon boss responded, "Pray for me."

Panetta, a staunch Catholic, is in Rome as part of a weeklong swing across Europe, meeting with defense ministers to talk about ongoing conflicts in Afghanistan and Mali. This is expected to be Panetta's last overseas trip as Pentagon chief, as he long has planned to step down once his replacement is confirmed.

The pontiff has been outspoken in pressing for peace, issuing urgent appeals to end the violence in Syria and urging the international community to spare no effort in seeking a political settlement to the conflict. Most recently he used his annual New Year's speech at the Vatican to call for an end to Syria's civil war. He has also pushed for peace in the Middle East, saying he hopes Jerusalem will one day become "a city of peace and not of division."

Wednesday's Vatican visit is Panetta's third papal audience.

The Italian-American Panetta, who was born in California, made the first trip to Italy in the 1950s, traveling with his parents to visit his grandparents. During that trip, Panetta made his first visit to St. Peter's Basilica.

Panetta made subsequent trips to Rome as a member of Congress, and had an audience with Pope John Paul II when he traveled to Rome with then-President Bill Clinton. He later had a second audience with Pope John Paul II in Washington.

While director of the CIA, Panetta visited the Vatican, but did not see the Pope.

On his overseas trips, Panetta often will go to Catholic mass at a local church.

Panetta, who often works his Italian ancestry into his speeches, told reporters traveling with him that this visit to Italy has a "lot of tremendous personal meaning for me, since I'm the son of Italian immigrants." He often talks about his parents' decision to come to America so that they could provide a better life for their children.

Lutheran college opens the door to same-sex wedding

When Eric Palmer came to Augustana College four years ago, he wasn't expecting to fall in love. And he certainly wasn't expecting to be a pioneer when he requested to use the chapel to declare his devotion to his fiance.

But his betrothed is Ethan Tarvin, also a senior at the liberal arts college, which is affiliated with the Evangelical Lutheran Church in America. When the Rock Island, Ill., school recently decided to allow its chapel to be used for the blessings of same-sex unions, another barrier quietly fell.

"I didn't have to wrestle with this. ... It was a matter of integrity," said President Steve Bahls, citing the school's anti-discrimination policy. "If you say you don't discriminate based on sexual orientation but you can't use our chapel, then you're a hypocrite."

A decade ago, Bahls said he would have rejected such a request. Even if he did agree, he would have faced swarms of angry alumni ? instead of the overwhelming support he received for what is believed to be the first of 26 ELCA colleges nationwide to take such a stand, he said.

Still, the issue of religiously affiliated colleges opening their facilities to same-sex weddings and commitment ceremonies can be tricky for administrators. Some Christian denominations don't recognize gay marriage while others require permission from higher authorities, such as local bishops.

Then, there's the issue of what to even call these rituals. Augustana is a 10-minute drive from Iowa, where same-sex couples can legally tie the knot. Illinois doesn't recognize such unions, though legislation has recently gained momentum and could be taken up in Springfield during the spring session.

For Palmer and Tarvin, their choice of venue for a fall 2013 wedding wasn't about activism, but deep ties to the campus where many life-changing experiences occurred.

"Augustana is just a very sentimental place for us," said Palmer, who met Tarvin in 2011, when he registered him to vote. The two hit it off and got engaged last April Fools' Day.

Said Tarvin: "I met Eric on campus, proposed on campus and it seemed only logical to have the ceremony in the chapel. ... It really represents my personal, professional and religious life."

They took the request to their college pastor, the Rev. Richard Priggie, who was cautiously optimistic, but who said he needed approval from higher up ? which is how the request landed on the president's desk.

In a 2009 statement, the churchwide assembly acknowledged that consensus on this matter doesn't exist in the ELCA and allowed congregations that choose to do so to find ways to recognize and support same-sex, monogamous relationships, according to the Rev. Mark Wilhelm, program director for ELCA colleges.

"The statement acknowledges that members of our church hold various convictions ? and Augustana is reflecting one angle on this," Wilhelm said.

Because the college is affiliated with the ELCA, but not a congregation, the final decision rested with the 58-year-old Bahls. "I asked myself: Is this consistent with church doctrine? Yes. Is it consistent with Augustana's doctrine. Yes. So, to give life to our anti-discrimination policy, I had to make it available to all."

Bahls informed the local bishop and the board of trustees, but did not issue a press release. The news leaked out in November and he braced himself for a firestorm ? which never happened.

"That was probably the biggest surprise is how this has been overwhelmingly accepted ? not unanimously, but for every negative comment, I received a dozen that were positive," said Bahls, who called each critic to discuss his verdict.

It's a far cry from an earlier era at religious colleges, where Scripture-quoting staff made sure that even heterosexual dancing was discouraged and curfews were strictly enforced. Some see Augustana's action as a sign that the pendulum has swung too far in the other direction.

"It's clear that Augustana and the ELCA has made a decision about this that most Christians in the world wouldn't agree with, although you wouldn't know it from this country," said the Rev. Paul Ulring of Lutheran CORE, a conservative umbrella organization.

It's not that the third-generation pastor is against change. In fact, he led the battle for social dancing ? and lost ? at his alma mater, Waldorf College, in 1967. But the lack of outcry over the legitimacy of same-sex unions is "telling," he said.

"It's a sad reality ... those who have objected have left the denomination," Ulring said.

For the newlyweds-to-be, however, the future holds nothing but joy. They'll graduate in May ? Palmer in political science and economics, Tarvin in music education ? and the world is a more welcoming place today than just a few years ago.

Palmer came out at age 15 in a small town in western Illinois. He was routinely ridiculed and one friend's mother even took him to an exorcist, he said.

Life wasn't much easier for Tarvin in suburban Milwaukee. He was raised in the Missouri Synod Lutheran Church, a traditional branch of Lutheranism, and waited until he arrived in Rock Island to live openly gay.

"I was very self-conscious of my sexuality and felt that I would not be welcome in my home congregation," Tarvin said. "I was genuinely surprised at the openness of the Augustana community."

"And now to have our ceremony here is just perfect," Palmer said.

Bahls says other leaders of ELCA-affiliated colleges could follow suit.

"I was first to make this decision because we had a request, but I'd like to think many of my colleagues would make the same decision," he said. "Our society and our colleges are changing and for that, I'm proud to be a symbol."

Smoking intensity and cancer markers predict seriousness of bladder cancer

Jan. 9, 2013 ? Smoking not only causes bladder cancer -- it also affects its course, in that people who smoke more have greater likelihood of developing more aggressive and deadly disease. That is one of the conclusions of a new study published early online in Cancer, a peer-reviewed journal of the American Cancer Society. The study also found that a panel of bladder cancer markers can predict which particular cases are at the highest risk for a fatal outcome.

Researchers have known that smoking is one of the most common causes of bladder cancer, but they've wondered whether it also affects how the disease progresses. To investigate, Richard J. Cote, MD, of the University of Miami Miller School of Medicine, and Anirban Mitra, MD, PhD, of the Keck School of Medicine of the University of Southern California, led a team that analyzed bladder tumors and smoking history in 212 multi-ethnic patients recruited through the Los Angeles County Cancer Surveillance Program between 1987 and 1996.

The researchers found that the bladder cancers that developed in individuals who smoked intensely were more likely to be deadly than bladder cancers that developed in those who never smoked, or who smoked less. The study also revealed that changes in particular proteins are often present in bladder cancers that have become deadly. "We have identified a panel of nine molecular markers that can robustly and reproducibly predict bladder cancer prognosis independent of standard clinical criteria and smoking history," said Dr. Mitra. Patients with alterations in six to nine markers had a very poor outcome, raising the hypothesis that these individuals could have benefited from more aggressive treatments.

Because the number of changes in these proteins was directly proportional to patients' health outcomes in a progressive fashion, the findings confirm the theory that an accumulation of changes is more important than individual changes in determining the characteristics of a given cancer. The link between smoking intensity and prognosis found in this study points to the incrementally harmful effects of smoking.

"The study's findings are extremely clinically relevant as bladder cancer is one of the most expensive malignancies to treat," said Dr. Cote, who is Director of the Genitourinary Malignancies Program at University of Miami's Sylvester Comprehensive Cancer Center. "Personalized patient management is urgently needed for this disease as current clinical stratification cannot predict outcomes of individual patients."
