What Lives in Your Gut?

As we enter a new year, many of us will start thinking—if only temporarily—about improving our diet and lifestyle habits. Maybe you'll resolve to drink more water, eat less fat, get more exercise.

But what does your gut want? A new citizen science project aims to find out.

"What diet should you be eating to achieve an optimal, healthy microbiome in your gut? We don't know yet but finding out could be the key to helping people overcome many chronic diseases," said Jeff Leach, co-founder of the American Gut project.

(Read about the secret world of microbes in the January 2013 issue of National Geographic magazine.)

The concept of the crowd-funded project is simple: Pay $99, get a sample collection kit, and mail back a test tube containing "a little bit of brown" swabbed from your used toilet paper. Participants will also be asked to log their food intake for three days and answer a detailed questionnaire about how and where they live.

"Are you a vegetarian? Were you born via C-section? Do you live in a rural or urban area? Do you have dogs? All of these things can influence your microbiome," Leach said.

In return, participants will receive an analysis revealing what organisms dwell in their gut and showing how their own microbial ecosystem compares to others—including a group of hunter-gatherers Leach has been studying in Tanzania. (That research has not yet been published, but he says it reveals "big differences" between the guts of people who consume a Western diet of highly processed foods and those who eat more traditional diets.)

"There's been a lot of research about the human microbiome recently, but the general public never gets to figure out what's in their gut unless you do something like this," said Leach.

Microbes play several vital roles in the gut, including maintaining the mucosal lining of the gastrointestinal tract, protecting against pathogens, and helping the body harvest calories and digest fiber.

Having too much or too little of certain bacteria could contribute to inflammation, a key factor in many chronic diseases. Recent studies have linked diabetes and obesity to imbalances in gut bacteria.

"We want people to understand that this is a major aspect of their health that's in their control," Leach said. "You're born with your genes, but you can shift your microbiome through diet and lifestyle changes."

About a thousand people have joined the project so far, and Leach is hoping another 3,000 or more will sign up to receive a kit before the February 1 deadline.

Quadruple Amputee Gets Two New Hands on Life

It's the simplest thing, the grasp of one hand in another. But Lindsay Ess will never see it that way, because her hands once belonged to someone else.

Growing up in Texas and Virginia, Lindsay, 29, was always one of the pretty girls. She went to college, did some modeling and started building a career in fashion, with an eye on producing fashion shows.

Then she lost her hands and feet.

Watch the full show in a special edition of "Nightline," "To Hold Again," TONIGHT at 11:35 p.m. ET on ABC

When she was 24 years old, Lindsay had just graduated from Virginia Commonwealth University's well-regarded fashion program when she developed a blockage in her small intestine from Crohn's Disease. After having surgery to correct the problem, an infection took over and shut down her entire body. To save her life, doctors put her in a medically-induced coma. When she came out of the coma a month later, still in a haze, Lindsay said she knew something was wrong with her hands and feet.

"I would look down and I would see black, almost like a body that had decomposed," she said.

The infection had turned her extremities into dead tissue. Still sedated, Lindsay said she didn't realize what that meant at first.

"There was a period of time where they didn't tell me that they had to amputate, but somebody from the staff said, 'Oh honey, you know what they are going to do to your hands, right?' That's when I knew," she said.

After having her hands and feet amputated, Lindsay adapted. She learned how to drink from a cup, brush her teeth and even text on her cellphone with her arms, which were amputated just below the elbow.

"The most common questions I get are, 'How do you type,'" she said. "It's just like chicken-pecking."

Despite her progress, Lindsay said she faced challenges being independent. Her mother, Judith Aronson, basically moved back into her daughter's life to provide basic care, including bathing, dressing and feeding. Having also lost her feet, Lindsay needed her mother to help put on her prosthetic legs.

"I've accepted the fact that my feet are gone, that's acceptable to me," Lindsay said. "My hands [are] not. It's still not. In my dreams I always have my hands."

Through her amputation recovery, Lindsay discovered a lot of things about herself, including that she felt better emotionally by not focusing on the life that was gone and how much she hated needing so much help but that she also truly depends on it.

"I'm such an independent person," she said. "But I'm also grateful that I have a mother like that, because what could I do?"

Lindsay said she found that her prosthetic arms were a struggle.

"These prosthetics are s---," she said. "I can't do anything with them. I can't do anything behind my head. They are heavy. They are made for men. They are claws, they are not feminine whatsoever."

For the next couple of years, Lindsay exercised diligently as part of the commitment she made to qualify for a hand transplant, which required her to be in shape. But the tough young woman now said she saw her body in a different way now.

Male lynxes duel to the death

These male lynxes were fighting for control of the lands behind them, and the females that live in it. In this case both survived, but they were lucky. In the previous two battles for this territory, the incumbent male was killed.

Between 2002 and 2011, this territory changed paws three times. The first male was killed in 2002, and his killer took over the area. He was in turn killed and supplanted in 2005.

His usurper, who had the code-name L-03134, held the territory until 2008 when he was driven out. L-03134 is on the left in the photo, losing to the male who went on to take his territory. The new male has since held off a challenger who tried to claim the territory in 2011.

Long-lived animals rarely fight to the death, because it often makes more sense for the weaker animal to give up the fight and try somewhere else. But in northern Sweden, male Eurasian lynxes face intense struggles for territory. They often hold their territories for years, partly because they are rarely hunted by humans, so challengers are forced to fight particularly hard if they are to have any hope of mating.

Football: AC Milan storm off pitch after racist chants

ROME: AC Milan striker Kevin-Prince Boateng stormed off the pitch on Thursday forcing the suspension of a friendly match against fourth-tier Pro Patria after racist chants from a group of fans for the opposing team.

"Pulling out was the right choice with something like this," Milan trainer Massimiliano Allegri said after the match was stopped in the 26th minute.

"We have to stop it with these uncouth acts. Italy as a country has to improve and become more civilised and intelligent," he told reporters.

Squad captain Massimo Ambrosini said: "That was intolerable, it was only a friendly! We couldn't have gone on like that, we had to give a signal."

Boateng picked up the ball, kicked it towards the Pro Patria stands and walked off the pitch of Pro Patria's home town of Busto Arsizio.

His teammates joined him despite Pro Patria players begging them to stay and whistles from many of the Pro Patria fans against the racists.

The 25-year-old Boateng, who has Ghanaian citizenship and played for Ghana at the 2010 World Cup, was previously at Tottenham, Borussia Dortmund and Portsmouth.

Apple said to be eyeing new display tech for next iPhone

Apple's iPhone 5.

CNET)

Apple's use of the so-called "in-cell" touch technology in the
iPhone 5 could be short-lived according to a new report that claims the company is already eyeing alternatives for its next iPhone model.

Citing supply chain rumors, The China Times (translation) says Apple is currently evaluating technology called Touch On Display from Innolux, the company formerly named Chimei Innolux which Apple last year listed as one of its component suppliers.

The reason for the change, the report claims, is due to interference with the current in-cell technology where both the display and touch are embedded in the same panel. By comparison, the Touch On technology offers "good" touch sensitivity with minimal thickness, something that's become increasingly import as mobile phones get thinner.

Display technology has been a major feature of the iPhone since Apple's first model, which at 3.5-inches was considerably larger than most competing smartphones when it was released. Apple later increased the pixel density while keeping the 3.5-inch size, technology it called the Retina Display. That same technology ended up on the
iPad and high-end versions of Apple's
MacBook Pro notebooks.

The display continues to be one of the most expensive parts of the iPhone. A virtual teardown by IHS iSuppli last September estimated the combined display and touchscreen to cost Apple $44, putting it well ahead of the components for wireless antennas, NAND flash memory, and the A-series processor.

Rumors have swirled in recent weeks that Apple is preparing an intermediary upgrade to the iPhone 5 for release as soon as this Spring. Alleged shots of its rear casing cropped up last month on a French technology blog that's been known to get accurate shots of Apple components in the past. Topeka Capital Markets analyst Brian White this week said that he expects the company to roll out a "5S" model in May or June with "more color patterns and screen sizes," similar to what Apple offers on its latest iPod touch models.

Pictures: Errant Shell Oil Rig Runs Aground Off Alaska, Prompts Massive Response

Waves lash at the sides of the Shell* drilling rig Kulluk, which ran aground off the rocky southern coast of Alaska on New Year's Eve in a violent storm.

The rig, seen above Tuesday afternoon, was "stable," with no signs of spilled oil products, authorities said. But continued high winds and savage seas hampered efforts to secure the vessel and the 150,000 gallons (568,000 liters) of diesel fuel and lubricants on board. The Kulluk came to rest just east of Sitkalidak Island (map), an uninhabited but ecologically and culturally rich site north of Ocean Bay, after a four-day odyssey, during which it broke free of its tow ships and its 18-member crew had to be rescued by helicopter.

The U.S. Coast Guard, state, local, and industry officials have joined in an effort involving nearly 600 people to gain control of the rig, one of two that Shell used for its landmark Arctic oil-drilling effort last summer. "This must be considered once of the largest marine-response efforts conducted in Alaska in many years," said Steve Russell, of Alaska's Department of Environmental Conservation.

The 266-foot (81-meter) rig now is beached off one of the larger islands in the Kodiak archipelago, a land of forest, glaciers, and streams about 300 miles (482 kilometers) south of Anchorage. The American Land Conservancy says that Sitkalidak Island's highly irregular coastline traps abundant food sources upwelling from the central Gulf of Alaska, attracting large numbers of seabirds and marine mammals. The largest flock of common murres ever recorded by the U.S. Fish and Wildlife Service was in Sitkalidak Strait, which separates the island from Kodiak. Sitkalidak also has 16 wild salmon rivers and archaeological sites tied to the Alutiiq native peoples dating back more than 7,000 years.

Shell incident commander Susan Childs said Monday night that the company's wildlife management team had started to assess the potential impact of a spill, and would be dispatched to the site when the weather permitted. She said the Kulluk's fuel tanks were in the center of the vessel, encased in heavy steel. "The Kulluk is a pretty sturdy vessel," she said. " It just remains to be seen how long it's on the shoreline and how long the weather is severe."

Senate Swears in Historic 20th Female Senator

Today the Senate will make history, swearing in a record-breaking 20 female senators -- four Republicans and 16 Democrats -- in office.

As the 113th Congress is sworn in today on Capitol Hill, ABC "World News" anchor Diane Sawyer has an exclusive joint interview with the historic class of female senators.

Diane Sawyer's complete interview will air on "World News" and "Nightline" tonight.

"I can't tell you the joy that I feel in my heart to look at these 20 gifted and talented women from two different parties, different zip codes to fill this room," Sen. Barbara Mikulksi, D-Md., said while surrounded by the group of women senators. "In all of American history only 16 women had served. Now there are 20 of us."

Senator-elect Deb Fischer, R-Neb., today becomes the first women to be elected as a senator in Nebraska.

"It was an historic election," Fischer said, "But what was really fun about it were the number of mothers and fathers who brought their daughters up to me during the campaign and said, "Can we get a picture? Can we get a picture?' Because people realize it and -- things do change, things do change."

Tammy Baldwin Becomes First Openly Gay Senator Watch Video

Elizabeth Warren Wins Massachusetts Senate Race Watch Video

The women senators all agree that women will be getting things done in this new Congress, a sign of optimism felt for the new Congress, after the bruising battles of the 112th Congress.

"We're in force and we're in leadership positions, but it's not just the position that we hold. I can tell you this is a can-do crowd," Mikulski said of both Democrats and Republican senators in the room. "We are today ready to be a force in American politics."

And while the number of women in the Senate today makes history, many of the women agreed that they want to keep fighting to boost those numbers.

Sen. Barbara Boxer, D-Calif., said that women are still "underrepresented" in the Senate.

"I think that until we get to 50, we still have to fight because it's still a problem," Boxer said. "I think this class as you look around, Republicans and Democrats. ... I think that because of this new class and the caliber of the people coming and the quality of the people coming, I think that hopefully in my lifetime -- and I really do hope and pray this is the case -- we will see 50 percent. "

No Sorority Here, Even With the Will to Work Together

The cooperation does not make them a "sorority," Sen. Dianne Feinstein, D-Calif., says. There are real differences in ideology and personality and they don't want their gender to define them as senators.

But the women also admit that they believe having more women in the room would help in fierce negotiations, compromise and legislating on Capitol Hill, traits they say do not come as naturally to their male colleagues in the Senate. That sentiment enjoys bipartisan support among the women of the Senate.

"What I find is with all due deference to our male colleagues, that women's styles tend to be more collaborative," Sen. Susan Collins, R-Maine, said.

Sen. Claire McCaskill, D-Mo., said by nature women are "less confrontational." Sen-elect Mazie Hirono, D-Hawaii, says that women are "problem solvers."

Sen. Amy Klobuchar, D-Minn., says that women have a camaraderie which helps in relationships that are key to negotiations on Capitol Hill, something she says comes natural to women more than men.

"I think there's just a lot of collaboration between the women senators and... advice and really standing up for each other that you don't always see with the men," she said.

Ice sheets of West Antarctica are warming fast

THE ice sheets of West Antarctica are warming much faster than we thought, suggesting swathes of it could melt and send global sea levels soaring.

Climatologists have struggled to work out whether Antarctica is warming, and how quickly, because it has few weather stations and the records from some are incomplete.

David Bromwich of Ohio State University in Columbus and his colleagues filled in the gaps for one key station using statistics and data from a climate model. They conclude that temperatures since 1958 have risen about 0.46 °C per decade - more than twice as fast as previously thought (Nature Geoscience, doi.org/j351).

But Michael Mann at Penn State University in University Park says that warmer ocean water flooding in underneath the sheet poses a greater threat.

US manufacturing rebounds in December

WASHINGTON: US manufacturing activity expanded slightly in December after contracting the previous month, the ISM monthly survey showed on Monday.

The Institute for Supply Management's manufacturing sector index rose to 50.7 last month from 49.5 in November, with 50 the break-even line between growth and contraction.

The index has hovered around that line for the past six months, the ISM said, reflecting weakness in both US and global economic growth.

Only seven of 18 manufacturing industries covered in the ISM survey actually reported growth in the month, and overall production growth slowed.

But the employment sub-index rose to 52.7 from 48.4, showing the industry returned to hiring at a modest clip in December.

Amazon Instant Video deal: 22 popular movies for $5 each

Want to rent a movie from Amazon Instant Video? Usually it'll cost you $4-5, depending on whether you choose the SD or HD version.

Today only, Amazon is letting you buy
22 popular movies for under $5 each.

And by "popular" I don't mean "Weekend at Bernies 2" and other Z-grade flicks you usually see at this price point. This sale includes Academy Award winners, personal favorites, and titles you'll find on AFI top-100 lists.

For example, you can get "Batman Begins" and "The Dark Knight" for $4.98 apiece (or $3.99 for the SD versions). Other good choices for action fans: "300" and "The Matrix."

If you're into drama, check out "The Blind Side," "The Departed," "The Town," and one of my top-five favorite movies of all time, "The Shawshank Redemption."

Like classics? How about "Casablanca," "Gone with the Wind," and "Singin' in the Rain"? Like comedy? There's "The Hangover" and "National Lampoon's Christmas Vacation" (which I always thought was a little overrated, but to each his own). Got kids? Let 'em watch and rewatch "The Goonies" and "Happy Feet."

Like I said, there's some mighty good stuff here, and if you were to buy these flicks from, say,
iTunes, most of them would cost you $15 each. (As of tomorrow, that's probably what they'll cost again on Amazon as well.)

Needless to say, if you're looking to expand your digital video library, this is a rare opportunity to score some big hits on the cheap.
