Ashton Kutcher files for divorce from Demi Moore

LOS ANGELES (AP) — Ashton Kutcher filed court papers Friday to end his seven-year marriage to actress Demi Moore.

The actor's divorce petition cites irreconcilable differences and does not list a date that the couple separated. Moore announced last year that she was ending her marriage to the actor 15 years her junior, but she never filed a petition.

Kutcher's filing does not indicate that the couple has a prenuptial agreement. The filing states Kutcher signed the document Friday, hours before it was filed in Los Angeles Superior Court.

Kutcher and Moore married in September 2005 and until recently kept their relationship very public, communicating with each other and fans on the social networking site Twitter. After their breakup, Moore changed her name on the site from (at)mrskutcher to (at)justdemi.

Kutcher currently stars on CBS' "Two and a Half Men."

Messages sent to Kutcher's and Moore's publicists were not immediately returned Friday.

Moore, 50, and Kutcher, 34, created the DNA Foundation, also known as the Demi and Ashton Foundation, in 2010 to combat the organized sexual exploitation of girls around the globe. They later lent their support to the United Nations' efforts to fight human trafficking, a scourge the international organization estimates affects about 2.5 million people worldwide.

Moore was previously married to actor Bruce Willis for 13 years. They had three daughters together — Rumer, Scout and Tallulah Belle — before divorcing in 2000. Willis later married model-actress Emma Heming in an intimate 2009 ceremony at his home in Parrot Cay in the Turks and Caicos Islands that attended by their children, as well as Moore and Kutcher.

Kutcher has been dating former "That '70s Show" co-star Mila Kunis.

The divorce filing was first reported Friday by People magazine.

Genetic Gamble : Drugs Aim to Make Several Types of Cancer Self-Destruct

C.J. Gunther for The New York Times

Dr. Donald Bergstrom is a cancer specialist at Sanofi, one of three companies working on a drug to restore a tendency of damaged cells to self-destruct.

For the first time ever, three pharmaceutical companies are poised to test whether new drugs can work against a wide range of cancers independently of where they originated — breast, prostate, liver, lung. The drugs go after an aberration involving a cancer gene fundamental to tumor growth. Many scientists see this as the beginning of a new genetic age in cancer research.

Great uncertainties remain, but such drugs could mean new treatments for rare, neglected cancers, as well as common ones. Merck, Roche and Sanofi are racing to develop their own versions of a drug they hope will restore a mechanism that normally makes badly damaged cells self-destruct and could potentially be used against half of all cancers.

No pharmaceutical company has ever conducted a major clinical trial of a drug in patients who have many different kinds of cancer, researchers and federal regulators say. “This is a taste of the future in cancer drug development,” said Dr. Otis Webb Brawley, the chief medical and scientific officer of the American Cancer Society. “I expect the organ from which the cancer came from will be less important in the future and the molecular target more important,” he added.

And this has major implications for cancer philanthropy, experts say. Advocacy groups should shift from fund-raising for particular cancers to pushing for research aimed at many kinds of cancer at once, Dr. Brawley said. John Walter, the chief executive officer of the Leukemia and Lymphoma Society, concurred, saying that by pooling forces “our strength can be leveraged.”

At the heart of this search for new cancer drugs are patients like Joe Bellino, who was a post office clerk until his cancer made him too sick to work. Seven years ago, he went into the hospital for hernia surgery, only to learn he had liposarcoma, a rare cancer of fat cells. A large tumor was wrapped around a cord that connects the testicle to the abdomen. “I was shocked,” he said in an interview this summer.

Companies have long ignored liposarcoma, seeing no market for drugs to treat a cancer that strikes so few. But it is ideal for testing Sanofi’s drug because the tumors nearly always have the exact genetic problem the drug was meant to attack — a fusion of two large proteins. If the drug works, it should bring these raging cancers to a halt. Then Sanofi would test the drug on a broad range of cancers with a similar genetic alteration. But if the drug fails against liposarcoma, Sanofi will reluctantly admit defeat.

“For us, this is a go/no-go situation,” said Laurent Debussche, a Sanofi scientist who leads the company’s research on the drug.

The genetic alteration the drug targets has tantalized researchers for decades. Normal healthy cells have a mechanism that tells them to die if their DNA is too badly damaged to repair. Cancer cells have grotesquely damaged DNA, so ordinarily they would self-destruct. A protein known as p53 that Dr. Gary Gilliland of Merck calls the cell’s angel of death normally sets things in motion. But cancer cells disable p53, either directly, with a mutation, or indirectly, by attaching the p53 protein to another cellular protein that blocks it. The dream of cancer researchers has long been to reanimate p53 in cancer cells so they will die on their own.

The p53 story began in earnest about 20 years ago. Excitement ran so high that, in 1993, Science magazine anointed it Molecule of the Year and put it on the cover. An editorial held out the possibility of “a cure of a terrible killer in the not too distant future.”

Companies began chasing a drug to restore p53 in cells where it was disabled by mutations. But while scientists know how to block genes, they have not figured out how to add or restore them. Researchers tried gene therapy, adding good copies of the p53 gene to cancer cells. That did not work.

Then, instead of going after mutated p53 genes, they went after half of cancers that used the alternative route to disable p53, blocking it by attaching it to a protein known as MDM2. When the two proteins stick together, the p53 protein no longer functions. Maybe, researchers thought, they could find a molecule to wedge itself between the two proteins and pry them apart.

The problem was that both proteins are huge and cling tightly to each other. Drug molecules are typically tiny. How could they find one that could separate these two bruisers, like a referee at a boxing match?

In 1996, researchers at Roche noticed a small pocket between the behemoths where a tiny molecule might slip in and pry them apart. It took six years, but Roche found such a molecule and named it Nutlin because the lab was in Nutley, N.J.

But Nutlins did not work as drugs because they were not absorbed into the body.

Roche, Merck and Sanofi persevered, testing thousands of molecules.

At Sanofi, the stubborn scientist leading the way, Dr. Debussche, maintained an obsession with p53 for two decades. Finally, in 2009, his team, together with Shaomeng Wang at the University of Michigan and a biotech company, Ascenta Therapeutics, found a promising compound.

The company tested the drug by pumping it each day into the stomachs of mice with sarcoma.

Naomi Gleit helps keep Facebook growing

The gig: As senior director of Facebook Inc.'s growth, engagement and mobile team, Naomi Gleit helps grow the social network's 1-billion-plus user base.

Facebook employee No. 29: Few people outside Facebook have heard of Gleit, but she's the second-longest-serving Facebook employee, after Facebook founder Mark Zuckerberg. Gleit, 29, talked her way into a job at Facebook on July 18, 2005 — her birthday. She was Facebook's 29th employee, coming on board shortly after the company hit 1 million users and before anyone had an inkling of the colossus it would become.

Dogged spirit: Unlike most other early employees who eventually dispersed to seek new fortunes, Gleit says she has no intention of leaving Facebook. She gets that tenacity from her "tiger mom," a computer programmer who ferried her to ballet, piano, karate and Chinese lessons, and her Jewish father, an immigration lawyer who took her to Hebrew school, she said. "I know it sounds completely irrational, but I had no doubt in 2005 that Facebook would be something incredible in the future," she said.

Rival social networks: Her passion for Facebook began before she was hired, when she was a Stanford undergraduate studying science, technology and society, an interdisciplinary major. She wrote her senior thesis on why Facebook beat out rival college social networking site Club Nexus at Stanford. (Club Nexus was started by Stanford student and Turkish software engineer Orkut Büyükkökten, who went on to create Orkut, Google's first attempt at a social network.) Getting in on the ground floor at Facebook made her feel like she was taking part in something bigger than herself, the same feeling she got volunteering for six months in a refugee camp in Botswana, she said.

Growing with Facebook: Gleit helped Facebook push beyond colleges to high schools and eventually to everyone. In late 2007, when the torrid growth pace temporarily cooled, Zuckerberg tapped a team of five to reignite it and asked Gleit to lead product management. It fell to the growth team to identify the obstacles to the company's momentum. In a company ruled by engineers, Gleit, who never studied programming, earned respect with her analytical approach and intuitive understanding of people. "I always believed that growth was the most important thing, the most important way to impact the company," she said. There are now more than 150 people on the team. "It's been an incredible learning experience," she said. "Each year is different."

That magic moment: Those who work closely with Gleit say part of her success early on was her ability to seize on the "magic moment" that makes users fall in love with Facebook. She made it simpler to sign up, and she helped people find friends as soon as they joined. She also helped Facebook spread quickly to new countries by enlisting users to translate the service into more than 80 languages. Gleit helps her team parachute into new markets and traverse less-familiar languages and cultures. It's something that comes from her own passion to see the world and have new experiences. She has taught on a Navajo reservation and lived in a Buddhist monastery in Thailand.

One billion users: Around noon Sept. 14, Zuckerberg gathered with Gleit and dozens of employees in front of a big screen as the number of Facebook users crossed 1 billion. "The scale was insane," she said. "But that is not the goal. When Mark talks about his vision for Facebook, he talks about being able to connect everyone in the world to the people that they care about and provide some value for them every single day."

A problem solver: Zuckerberg calls on Gleit for high-profile projects. In May 2010, when Facebook was under siege because of how it was handling users' personal information, he put Gleit in charge of simplifying privacy settings. Last year she worked on a popular feature that lets users subscribe to a News Feed without having to become Facebook friends.

Betting on mobile: Now Gleit is focused on the future: mobile devices and how they can unlock emerging markets. Gleit knew back in 2011 that people would begin to log on to Facebook from mobile devices in greater numbers than from desktops, particularly in the developing world. So she traveled to Tel Aviv to buy Snaptu, which makes software that helps people on low-tech phones access Facebook, and she brought the whole team back to Silicon Valley with her. Now Facebook is surging in popularity on mobile devices in Tokyo and Nairobi, Kenya. "I have always been interested in technology and how it can be used to improve lives," Gleit said.

Prime Minister Mario Monti of Italy steps down

LONDON — Prime Minister Mario Monti, the technocrat who guided Italy through economic turbulence for 13 months after scandal-plagued Silvio Berlusconi left office, resigned Friday to make way for new elections.

Monti, a former economics professor and European Union commissioner, was appointed to the office, with a Cabinet of academics and economists and broad support to bring the country back from the brink of financial disaster.

"A year ago this government was launched, and today — not because of a Maya prophecy — we must bring it to an end," Monti quipped as he spoke to colleagues at an annual reception.

His resignation was provoked in part by Berlusconi's announcements this month that he was withdrawing his center-right Freedom Party's support for Monti's budget reforms and would return to the political arena, leading the party into elections.

Berlusconi's attempt to regain the prime minister's post comes despite his conviction in a corruption case and his ongoing trial on charges of paying for sex with a 17-year-old girl.

Monti's resignation followed Parliament's final approval of the last of his budgetary measures. He and his Cabinet will remain in power as caretakers until the elections, expected in mid-February.

The short run-up to the elections is fraught with questions. Monti, now a senator for life, could seek an active role in the coming government, though he has said that he has no such ambition.

He has not shown his hand yet but recently met with a new group of centrist and pro-European parties. However, such an alliance is expected to command no more than about 15% of an electorate fast losing faith in Monti's austerity cuts, seeing only Italy's rising unemployment and lack of growth.

He is expected to announce his decision Sunday.

The probable favorite in the upcoming election is a left-wing coalition under former communist politician Pier Luigi Bersani, leader of the Democratic Party, who is not opposed to Monti's reforms but must answer to powerful labor unions. According to recent polls, Bersani's coalition could attract support from about 30% of the voters.

The dwindling but still strong center-right vote is largely divided between the maverick anti-austerity Five Star Alliance movement led by TV comedian Beppe Grillo and Berlusconi's Freedom Party.

In a meeting with ambassadors Friday morning, Monti said that he thought Italy's standing had improved both economically and internationally in the last year and that he saw "an increase in Italy's authority and credibility on the international scene."

TSX ends flat as RIM buckles, gold miners bounce

TORONTO (Reuters) – Canada‘s main stock index ended little changed on Friday as gold miners gained on safe-haven buying amid U.S. budget uncertainty, while BlackBerry maker Research In Motion Ltd plunged more than 20 percent.

The index’s materials sector, which includes miners, rose 0.4 percent. Even though the price of gold was near its lowest level in four months, the gold-mining sub-sector added 0.9 percent as investors fretted over stalled U.S. budget talks that could throw Canada’s largest trading partner back into recession.

“As our tiptoes are over the (U.S.) fiscal cliff and we’re looking over the abyss, the markets are upset obviously, and this is sort of putting a damper on the stocks,” said John Ing, president of Maison Placements Canada.

“But we’ve had a mixed reaction in Canada, mainly because the resources have been much better, like gold for example, which is hedging into the uncertainty (around the budget talks),” he said, noting gold miners had been under pressure for the last two weeks.

Miner Barrick Gold Corp edged up 0.2 percent to C$ 33.29. Centerra Gold Inc jumped more than 3 percent to C$ 9.10.

Gold miners are playing catch-up after underperforming throughout the year and could rise further in 2013, said Gavin Graham, president at Graham Investment Strategy.

Shares of RIM dropped 22.2 percent to C$ 10.86 on fears that a new fee structure for its high-margin services segment could put pressure on the business that has set the company apart from its competitors.

The Toronto Stock Exchange‘s S&P/TSX composite index <.gsptse> fell 3.01 points, or 0.02 percent, to end at 12,385.70. It gained 0.7 percent for the week.</.gsptse>

Efforts to avoid the looming U.S. “fiscal cliff” were thrown into disarray on Friday with finger-pointing lawmakers fleeing Washington for Christmas vacations even as the year-end deadline for action edged ever closer.

Graham said that until a deal is reached in the U.S. budget talks, investors will avoid economically sensitive Canadian stocks and those most closely tied to the U.S. economy: auto parts manufacturers, forestry companies and resource stocks generally.

“The resource sectors in Canada, which is half of the index, is going to be adversely affected, correctly or not,” he said.

“Chinese demand is likely to pick up somewhat now with the new leadership there but people will be focused on the U.S. given that it is still by far the most important export market for Canada.”

The New Old Age Blog: The Ex-Wives Club

Weather permitting, Kappy Lundy and Barbara Thompson are heading out to Vancouver, Wash., on Saturday night to have a holiday dinner with the parents of their daughter’s husband.

Yes, these women both mothered the same children — now grown and with children of their own. Ms. Lundy is their biological parent; Ms. Thompson is the stepmother who married their father after he and Ms. Lundy divorced.

But that doesn’t really begin to describe their relationship. Over more than 40 years, these two have been friends and what they call “wife-in-laws,” in addition to moms-in-tandem. Now, they’re so close they feel like sisters, they say.

There’s yet another dimension to this relationship that makes it so unusual: Ms. Lundy, who is 71, has become a caregiver for Ms. Thompson, who’s 67 and was given a diagnosis of mild cognitive impairment in 2009.

One wife caring for another, through thick and through thin – think about that. It’s another example of how the new old age is spawning unusual — and creative — alliances.

Ms. Lundy went with Ms. Thompson to eight months of classes on memory loss offered by the Alzheimer’s Association chapter in Portland, Ore., where the two women live. And now they go together to monthly meetings of the Wild Bunch, a group of people with dementia and their caregivers who’ve come together to provide each other emotional support. (More on that group to come in a future post.)

Ms. Lundy talks to Ms. Thompson every day and tries to get together with her once a week.

“We’re just really good friends, and we want to know what’s going on, what are you doing, like everybody else,” said Ms. Thompson, who moved into an independent living facility in Portland nearly a year ago, after Ms. Lundy helped pack up her previous apartment.

Ms. Lundy, who lives across town, about 20 minutes away, said: “We’ll go to happy hour together and have a little toddy and maybe a nice meal. And crack up – she makes me laugh.”

Both women grew up in Eugene, Ore., but became friends later, after they moved to Portland in their 20s. Their favorite haunt was the Goose Hollow Inn, a tavern where artists, architects and writers would congregate. Ms. Lundy and her husband began to socialize regularly with Ms. Thompson and her first husband.

“She’s full of life and fun – a gypsy at heart,” is how Ms. Thompson describes Ms. Lundy.

“She’s funny and smart and a really good listener,” is how Ms. Lundy describes Ms. Thompson.

When Ms. Lundy’s marriage to Phil Thompson — a handsome bear of a man, with a charismatic personality and an artistic sensibility — began falling apart, both members of the couple turned to their friend Barbara for support. “She listened to me and my anger, and she listened to him about how he was hurting,” says Ms. Lundy, who was separated from her husband for a year before the divorce was official.

There were no hard feelings when Phil’s feelings toward Barbara turned romantic, Ms. Lundy says. But she didn’t see the couple much during subsequent years of work and travel abroad. During those years, her children, Jessica and David, stayed with their father in Portland.

Eventually, Ms. Lundy came home and was invited to holidays at the Thompson house. She grew close to Barbara again and let go of negative feelings toward her former husband, she said. Over time, they became bound together as family.

“It’s incredible,” their daughter said. “They’re just really caring for each other and not threatened by each other.

“My dad got a big kick out of it and would always introduce them as ‘my wives.’”

When Phil Thompson died in August 2008, both women were at his bedside. And when Ms. Thompson started having memory problems months later, Ms. Lundy was one of the first to notice. “We could see she wasn’t remembering things, but she said, ‘This is my grief,’” Ms. Lundy recalled. It became clear something else might be going on as problems persisted and a doctor’s evaluation yielded the mild cognitive impairment diagnosis.

Ms. Thompson described her reaction to that information: “It was scary. Very scary. I didn’t know if it meant the end of my freedom, of my ability to just live my own life.”

For her part, Ms. Lundy said: “The hardest thing for me from the very beginning was to see my party pal and my dear, dear friend changing. It was very frustrating to me. And very hurtful. I wanted to support her. But sometimes I didn’t have the patience. Because, you know, she wasn’t acting like Barbara. It’s taken a while, but slowly, slowly, slowly and surely, I’ve accepted that this is who Barbara is.”

Ms. Lundy isn’t the only caregiver for Ms. Thompson: Jessica and David, her stepchildren, and two close friends also help out, as needed.

For Ms. Lundy, the uncertainty associated with her friend’s mild cognitive impairment diagnosis is hard to live with. Will it progress to dementia? Will it stay stable, or even get better? The doctor can’t say, and “all that not-knowing business is unsettling,” she said.

Becoming a caregiver has “made our friendship even stronger, I think,” Ms. Lundy says. “We’re closer now. Even though we’ve been friends for years and years, I never felt responsible for her before.”

For Ms. Thompson, what’s hardest is living alone after nearly 30 years of being married to Phil and worrying about losing her independence — notably, her ability to continue driving.

“I feel isolated with the disease,” she said. “And being alone in a new apartment with lots of strangers here has been a little difficult.”

“I’m very grateful to Kappy,” Ms. Thompson said. “I didn’t used to feel that she would be this way. She was always doing her own thing. But she has definitely reached out, beyond what most people would do.”

On Christmas the two women will be at Jessica’s house, arriving at around noon, after the grandchildren have opened their presents, and staying through the late afternoon. After the holidays, Ms. Lundy says she plans to take Ms. Thompson out more often and “have a couple of beers and a laugh and be happy and just be Barbie and Kappy,” two old friends, enjoying each other’s company.

This is the one of the most unusual caregiving relationships I know of. It reaffirms what I’ve been told several times: You never know who will end up being there for you when you need help. Sometimes the people we expect will care for us don’t, and others step forward. Has that been your experience?

Stocks sink after Republicans cancel budget vote

Stocks are closing sharply lower after House Republicans called off a vote on tax rates.

That left federal budget talks in disarray 10 days before sweeping tax increases and government spending cuts are set to take effect.

The Dow Jones industrial average lost 120 points to close at 13,191 Friday. It had been down as much as 189.

The Standard & Poor's 500 index fell 13 points to 1,430. The Nasdaq composite index fell 29 to 3,021.

The House bill would have raised taxes on Americans making at least $1 million per year and locked in decade-old tax cuts for Americans making less.

Two stocks fell for every one that rose on the New York Stock Exchange. Volume was 4.7 billion shares, higher than the recent average.

Boehner rejects Democrats' push for immediate vote on gun bill

WASHINGTON -- House Speaker John A. Boehner rejected calls from Democrats to schedule a vote on new gun restrictions before the end of the year, saying he wants to wait for recommendations from a newly formed White House task force before committing to a legislative response to the mass shooting at a Connecticut school.

“When the vice president's recommendations come forward, we'll certainly take them into consideration,’’ Boehner (R-Ohio) said Thursday in his first public comments on calls for new gun legislation since the slaying of 20 students and six adults at Sandy Hook Elementary School. “But at this point I think our hearts and souls ought to be to think about those victims in this horrible tragedy.”

President Obama on Wednesday said he had asked Vice President Joe Biden to lead a task force to come up with initiatives to stem gun violence by the end of next month. House Democratic Leader Nancy Pelosi of San Francisco and fellow Democrats have pressed for an immediate vote on a long-stalled bill that would ban ammunition magazines containing more than 10 rounds.

Obama has outlined a slightly slower pace for action, urging Congress to hold a vote “in a timely manner” in the new year.

Both Obama and Democrats on Capitol Hill say they are trying to seize on what appears to be a burst of momentum behind gun legislation in the wake of the Newtown, Conn., tragedy. Similar efforts initiated after other high-profile shootings faltered after national attention veered elsewhere.

Biden held the first meeting of the task force Thursday, gathering several cabinet members and White House officials with a group of local law enforcement leaders. In remarks before the meeting, the vice president noted his work on the 1994 crime bill, which banned the sale of some assault weapons, and said he would again be working closely with police groups to craft proposals.

“What I think the public has learned about you is you have a much more holistic view of how to deal with violence on our streets and in our country that you’re ever given credit for,” Biden told the law enforcement officials. “I want to hear your views because, for anything to get done, we’re going to need your advocacy.”
