Novelties: Single-Incision Surgery, Via New Robotic Systems

SURGEONS once made incisions large enough to get to a gallbladder or other organs by using conventional tools they held in their own hands. Today, many sit at a computer console instead, guiding robotic arms that enter the patient’s body through small openings not much larger than keyholes.

But even this minimally invasive surgery usually requires multiple incisions: one for the camera system showing the way to the surgeon at the console, and others for each of the robotic arms that do the cutting and stitching.

Now there are robotic systems — one on the market, others in development — that are even less intrusive. They require only a single, small incision through which the robotic arms and camera enter.

This could lead to faster recovery, said Dr. Michael Hsieh, a Stanford professor and a urologist at Lucile Packard Children’s Hospital and Stanford Hospital. “There’s only one wound to heal with this procedure, rather than three,” he said.

Dr. Hsieh, who performs abdominal surgery on small children, uses minimally invasive techniques that typically now require three incisions. His patients generally go home a day or two after surgery, he said, “but I think they would recover more quickly if I could reduce my multiple incisions to just one,” he said. “And there will be less scarring, or even no scarring, if you enter through the navel.”

He will soon have a chance to try out the new method on his patients. Stanford Hospital is buying a system from Intuitive Surgical called Single-Site that requires only a single incision of about one inch. The system, approved by the Food and Drug Administration only for gallbladder removal, is used as an add-on to a basic robotic system from Intuitive, known as the da Vinci Si.

The Si costs $1.3 million to $2.2 million, said Angela Wonson, a spokeswoman for Intuitive, based in Sunnyvale, Calif. The Single-Site can add $60,000 or more to the bill, or far less, depending in part on the equipment that hospitals might already have.

The East Jefferson General Hospital in Metairie, La., has bought a Single-Site system. Seated at a computer there, Dr. Joseph Uddo Jr. can control the instruments, which can enter the body by way of one incision in the navel. Surgical instruments like scissors are at the ends of the robotic arms. “To change a tool, you take out one instrument and load in another,” he said.

ANOTHER surgical robotic system, now in development, enters the body through a remarkably small incision — six-tenths of an inch, or 15 millimeters. The robot was designed by Drs. Dennis Fowler and Peter Allen of Columbia University and Dr. Nabil Simaan of Vanderbilt University. Once inside the body, it unfolds to reveal a camera system and two snakelike arms that perform the surgery. The system has been licensed to Titan Medical in Toronto.

Minimally invasive surgery through a single incision can also be performed with long, thin laparoscopic tools that surgeons wield as they watch a video monitor. But single-incision laparoscopic surgery with hand-held instruments can have problems, said Dr. Adrian Park, chairman of the department of surgery at the Anne Arundel Medical Center in Annapolis, Md., who specializes in minimally invasive gastrointestinal surgery. One difficulty is its ergonomic challenge to doctors, while another is the pressure that the tools place on tissue during single-incision operations.

Robotic systems, by contrast, are likely to ease single-incision surgery, said Jeffrey J. Tomaszewski, a fellow in urologic oncology at the Fox Chase Cancer Center in Philadelphia.

“Robots are an extension and multiplier of our own surgical hands,” Dr. Tomaszewski said. He has done traditional laparoscopic surgery with hand-held instruments, including operations through a single incision. “But you can be working at constrained angles,” he said. “A robot can improve the angle of workability.”

Robotic systems, though, have yet to show that they are always worth the extra money they cost. Such proof will take time, said Allison Okamura, an associate professor of mechanical engineering at Stanford who directs the Collaborative Haptics and Robotics in Medicine Lab. “The jury is still out because of the longevity of the studies that are required,” she said.

Dr. Tomaszewski agreed. “We surgeons love using the robot,” he said. “But the question is, and what we all have to fight hard to do, is to determine for what procedure the robotic approach provides the best benefit.”

Dr. Hsieh says he hopes that single-site robotic systems will someday bring a benefit he’s long dreamed about.

“We may get to the point where we do outpatient, scarless robotic surgery,” he said. “That’s what I’m shooting for.”

You for Sale: Your Online Attention, Bought in an Instant by Advertisers

Monica Almeida/The New York Times

Frank Addante, 36, chief executive of the Rubicon Project, says that 97 percent of American Internet users encounter its electronic ad sales system every month. And most aren’t even aware of it.

YOU can be sold in seconds.

Beverly Orr

“Online consumers are being bought and sold like chattel,” says Jeffrey Chester, executive director of the Center for Digital Democracy.

No, wait: make that milliseconds.

The odds are that access to you — or at least the online you — is being bought and sold in less than the blink of an eye. On the Web, powerful algorithms are sizing you up, based on myriad data points: what you Google, the sites you visit, the ads you click. Then, in real time, the chance to show you an ad is auctioned to the highest bidder.

Not that you’d know it. These days in the hyperkinetic world of digital advertising, all of this happens automatically, and imperceptibly, to most consumers.

Ever wonder why that same ad for a car or a couch keeps popping up on your screen? Nearly always, the answer is real-time bidding, an electronic trading system that sells ad space on the Web pages people visit at the very moment they are visiting them. Think of these systems as a sort of Nasdaq stock market, only trading in audiences for online ads. Millions of bids flood in every second. And those bids — essentially what your eyeballs are worth to advertisers — could determine whether you see an ad for, say, a new Lexus or a used Ford, for sneakers or a popcorn maker.

One big player in this space is the Rubicon Project. Never heard of it? Consider this: Rubicon, based in Los Angeles, has actually eclipsed Google in one crucial area — the percentage of Internet users in the United States reached by display ads sold through its platform, according to comScore, a digital analytics company.

Rubicon is among a handful of technology companies that have quietly developed automated ad sales systems for Web site operators. The bidders are marketers seeking to identify their best prospects and pitch them before they move to the next Web page. It is a form of high-frequency trading — that souped-up business of algorithm-loving Wall Streeters. But in this case, the prize is the attention of ordinary people. And it all depends on data-mining to instantly evaluate the audiences available to see those online display ads, the ones that appear on Web sites next to or around content.

In industry parlance, each digital ad space is an impression. The value of an impression depends on several factors, like the size of the ad, the type of person who is available to see it and that person’s location.

“The first impression seen by a high-value person on the opening page of a major newspaper first thing in the morning has a different value than a user from China who is 12 and has been on the Web all day long playing games,” says Frank Addante, the founder and chief executive of Rubicon.

Yet for most of us, real-time bidding is invisible. About 97 percent of American Internet users interact with Rubicon’s system every month, Mr. Addante says, and most of them aren’t aware of it.

That worries some federal regulators and consumer advocates, who say that such electronic trading systems could unfairly stratify consumers, covertly offering better pricing to certain people while relegating others to inferior treatment. A computer-generated class system is one risk, they say, of an ad-driven Internet powered by surveillance.

“As you profile more and more people, you’ll start to segregate people into ‘the people you can get money out of’ and ‘the people you can’t get money out of,’ ” says Dan Auerbach, a staff technologist at the Electronic Frontier Foundation, a digital civil rights group in San Francisco, who formerly worked in digital ad data-mining. “That is one of the dangers we should be worried about.”

Of course, ad agencies and brands can tailor ads to Web users without real-time bidding. They can also buy ads without aiming them at narrow audience groups. But for marketers, the marriage of ad- and audience-buying is one of the benefits of real-time bidding.

Not so long ago, they simply bought ad spaces based on a site’s general demographics and then showed every visitor the same ad, a practice called “spray and pray.” Now marketers can aim just at their ideal customers — like football fans who earn more than $100,000 a year, or mothers in Denver in the market for an S.U.V. — showing them tailored ads at the exact moment they are available on a specific Web page.

“We are not buying content as a proxy for audience,” says Paul Alfieri, the vice president for marketing at Turn, a data management company and automated buy-side platform for marketers based in Redwood City, Calif. “We are just buying who the audience is.”

Still, for many consumer advocates, real-time bidding resembles nothing so much as a cattle auction.

“Online consumers are being bought and sold like chattel,” says Jeffrey Chester, the executive director of the Center for Digital Democracy, a consumer group in Washington that has filed a complaint about real-time bidding with the Federal Trade Commission. “It’s dehumanizing.”

FRANK ADDANTE is 36 years old and given to wearing black shirts with a white Rubicon logo on the front. Rubicon is the fifth company he has started or helped to found.

In 1996, in his dorm room at the Illinois Institute of Technology, he developed and introduced a search engine. He later helped found L90, a digital ad technology company that went public and was later acquired by DoubleClick. His fourth enterprise, StrongMail Systems, provides e-mail delivery infrastructure to large companies.

Gaza Clash Escalates With Deadliest Israeli Strike

Bernat Armangue/Associated Press

Smoke rose over Gaza City on Sunday, as Israel widened its range of targets to include buildings used by the news media.

CAIRO — Emboldened by the rising power of Islamists around the region, the Palestinian militant group Hamas demanded new Israeli concessions to its security and autonomy before it halts its rocket attacks on Israel, even as the conflict took an increasing toll on Sunday.

Pavel Wolberg for The New York Times

 A woman and her child took cover in the southern Israeli town of Ashod, which was the target of several missiles on Sunday.

After five days of punishing Israeli airstrikes on the Hamas-controlled Gaza Strip and no letup in the rocket fire in return, representatives of Israel and Hamas met separately with Egyptian officials in Cairo on Sunday for indirect talks about a truce.

The talks came as an Israeli bomb struck a house in Gaza on Sunday afternoon, killing 11 people, in the deadliest single strike since the conflict between Israel and Hamas escalated on Wednesday. The strike, along with several others that killed civilians across the Gaza Strip, signaled that Israel was broadening its range of targets on the fifth day of the campaign.

By the end of the day, Gaza health officials reported that 70 Palestinians had been killed in airstrikes since Wednesday, including 20 children, and that 600 had been wounded. Three Israelis have been killed and at least 79 wounded by unrelenting rocket fire out of Gaza into southern Israel and as far north as Tel Aviv.

Hamas, badly outgunned on the battlefield, appeared to be trying to exploit its increased political clout with its ideological allies in Egypt’s new Islamist-led government. The group’s leaders, rejecting Israel’s call for an immediate end to the rocket attacks, have instead laid down sweeping demands that would put Hamas in a stronger position than when the conflict began: an end to Israel’s five-year-old embargo of the Gaza Strip, a pledge by Israel not to attack again and multinational guarantees that Israel would abide by its commitments.

Prime Minister Benjamin Netanyahu of Israel stuck to his demand that all rocket fire cease before the air campaign lets up, and Israeli tanks and troops remained lined up outside Gaza on Sunday. Tens of thousands of reserve troops had been called up. “The army is prepared to significantly expand the operation,” Mr. Netanyahu said at the start of a cabinet meeting.

Reda Fahmy, a member of Egypt’s upper house of Parliament and of the nation’s dominant Islamist party, who is following the talks, said Hamas’s position was just as unequivocal. “Hamas has one clear and specific demand: for the siege to be completely lifted from Gaza,” he said. “It’s not reasonable that every now and then Israel decides to level Gaza to the ground, and then we decide to sit down and talk about it after it is done. On the Israeli part, they want to stop the missiles from one side. How is that?”

He added: “If they stop the aircraft from shooting, Hamas will then stop its missiles. But violence couldn’t be stopped from one side.”

Hamas’s aggressive stance in the cease-fire talks is the first test of the group’s belief that the Arab Spring and the rise in Islamist influence around the region have strengthened its political hand, both against Israel and against Hamas’s Palestinian rivals, who now control the West Bank with Western backing.

It also puts intense new pressure on President Mohamed Morsi of Egypt, a former leader of the Muslim Brotherhood who was known for his fiery speeches defending Hamas and denouncing Israel. Mr. Morsi must now balance the conflicting demands of an Egyptian public that is deeply sympathetic to Hamas and the Palestinian cause against Western pleadings to help broker a peace and Egypt’s need for regional stability to help revive its moribund economy.

Indeed, the Egyptian-led cease-fire talks illustrate the diverging paths of the Muslim Brotherhood and Hamas, a Palestinian offshoot of the original Egyptian Islamist group. Hamas has evolved into a more militant insurgency and is labeled a terrorist organization by the United States and Israel, while the Brotherhood has effectively become Egypt’s ruling party. Mr. Fahmy said in an interview in March that the Brotherhood’s new responsibilities required a step back from its ideological cousins in Hamas, and even a new push to persuade the group to compromise.

The iEconomy: As Boom Lures App Creators, Tough Part Is Making a Living

Daniel Rosenbaum for The New York Times

Shawn and Stephanie Grimes’s efforts have cost $200,000 in lost income and savings, but their apps have earned less than $5,000 this year.

ROSEDALE, Md. — Shawn and Stephanie Grimes spent much of the last two years pursuing their dream of doing research and development for Apple, the world’s most successful corporation.

But they did not actually have jobs at Apple. It was freelance work that came with nothing in the way of a regular income, health insurance or retirement plan. Instead, the Grimeses tried to prepare by willingly, even eagerly, throwing overboard just about everything they could.

They sold one of their cars, gave some possessions to relatives and sold others in a yard sale, rented out their six-bedroom house and stayed with family for a while. They even cashed in Mr. Grimes’s 401(k).

“We didn’t lose any sleep over it,” said Mr. Grimes, 32. “I’ll retire when I die.”

The couple’s chosen field is so new it did not even exist a few years ago: writing software applications for mobile devices like the iPhone or iPad. Even as unemployment remained stubbornly high and the economy struggled to emerge from the recession’s shadow, the ranks of computer software engineers, including app writers, increased nearly 8 percent in 2010 to more than a million, according to the latest available government data for that category. These software engineers now outnumber farmers and have almost caught up with lawyers.

Much as the Web set off the dot-com boom 15 years ago, apps have inspired a new class of entrepreneurs. These innovators have turned cellphones and tablets into tools for discovering, organizing and controlling the world, spawning a multibillion-dollar industry virtually overnight. The iPhone and iPad have about 700,000 apps, from Instagram to Angry Birds.

Yet with the American economy yielding few good opportunities in recent years, there is debate about how real, and lasting, the rise in app employment might be.

Despite the rumors of hordes of hip programmers starting million-dollar businesses from their kitchen tables, only a small minority of developers actually make a living by creating their own apps, according to surveys and experts. The Grimeses began their venture with high hopes, but their apps, most of them for toddlers, did not come quickly enough or sell fast enough.

And programming is not a skill that just anyone can learn. While people already employed in tech jobs have added app writing to their résumés, the profession offers few options to most unemployed, underemployed and discouraged workers.

One success story is Ethan Nicholas, who earned more than $1 million in 2009 after writing a game for the iPhone. But he says the app writing world has experienced tectonic shifts since then.

“Can someone drop everything and start writing apps? Sure,” said Mr. Nicholas, 34, who quit his job to write apps after iShoot, an artillery game, became a sensation. “Can they start writing good apps? Not often, no. I got lucky with iShoot, because back then a decent app could still be successful. But competition is fierce nowadays, and decent isn’t good enough.”

The boom in apps comes as economists are debating the changing nature of work, which technology is reshaping at an accelerating speed. The upheaval, in some ways echoing the mechanization of agriculture a century ago, began its latest turbulent phase with the migration of tech manufacturing to places like China. Now service and even white-collar jobs, like file clerks and data entry specialists or office support staff and mechanical drafters, are disappearing.

“Technology is always destroying jobs and always creating jobs, but in recent years the destruction has been happening faster than the creation,” said Erik Brynjolfsson, an economist and director of the M.I.T. Center for Digital Business.

Still, the digital transition is creating enormous wealth and opportunity. Four of the most valuable American companies — Apple, Google, Microsoft and I.B.M. — are rooted in technology. And it was Apple, more than any other company, that set off the app revolution with the iPhone and iPad. Since Apple unleashed the world’s freelance coders to build applications four years ago, it has paid them more than $6.5 billion in royalties.

The Neediest Cases: Emerging From a Bleak Life to Become Fabulous Phil

For years, Phillip Johnson was caught in what seemed like an endless trench of bad luck. He was fired from a job, experienced intensifying psychological problems, lost his apartment and spent time in homeless shelters. At one point, he was hospitalized after overdosing on an antipsychotic drug.

“I had a rough road,” he said.

Since his hospital stay two years ago, and despite setbacks, Mr. Johnson, 27, has been getting his life on track. At Brooklyn Community Services, where he goes for daily counseling and therapy, everybody knows him as Fabulous Phil.

“Phillip is a light, the way he evokes happiness in other people,” his former caseworker, Teresa O’Brien, said. “Phillip’s character led directly to his nickname.”

About six months ago, with Ms. O’Brien’s help, Mr. Johnson started an event: Fabulous Phil Friday Dance Party Fridays.

One recent afternoon at the agency, 30 clients and a few counselors were eating cake, drinking soft drinks and juice, and grooving for 45 minutes to Jay-Z and Drake pulsating from a boom box.

Mr. Johnson’s voice rose with excitement when he talked about the party. Clients and counselors, he said, “enjoy themselves.”

“They connect more; they communicate more,” he continued. “Everybody is celebrating and laughing.”

The leadership Mr. Johnson now displays seems to be a far cry from the excruciatingly introverted person he was.

As an only child living with his single mother in public housing in Bedford-Stuyvesant, Brooklyn, he said, he tended to isolate himself. “A lot of kids my age would say, ‘Come outside,’ but I would always stay in my room,” he said. He occupied himself by writing comic books or reading them, his favorites being Batman and Spiderman because, he said, “they were heroes who saved the day.”

After graduating from high school in 2003, he worked odd jobs until 2006, when he took a full-time position at a food court at La Guardia Airport, where he helped to clean up. The steady paycheck allowed him to leave his mother’s apartment and rent a room in Queens.

But the depression and bleak moods that had shadowed him throughout middle and high school asserted themselves.

“My thinking got confused,” he said. “Racing thoughts through my mind. Disorganized thoughts. I had a hard time focusing on one thing.”

In 2008, after two years on the job, Mr. Johnson was fired for loud and inappropriate behavior, and for being “unpredictable,” he said. The boss said he needed counseling. He moved back in with his mother, and in 2009 entered a program at an outpatient addiction treatment service, Bridge Back to Life. It was there, he said, that he received a diagnosis of schizophrenia and help with his depression and marijuana use.

But one evening in May 2010, he had a bout with insomnia.

He realized the antipsychotic medication he had been prescribed, Risperdal, made him feel tired, he said, so he took 12 of the pills, rather than his usual dosage of two pills twice a day. When 12 did not work, he took 6 more.

“The next morning when I woke up, it was hard for me to breathe,” he said.

He called an ambulance, which took to Woodhull Hospital. He was released after about a month.

Not long after, he returned to his mother’s apartment, but by February 2011, they both decided he should leave, and he relocated to a homeless shelter in East New York, where, he said, eight other people were crammed into his cubicle and there were “bedbugs, people lying in your bed, breaking into your locker to steal your stuff.”

In late spring 2011, he found a room for rent in Manhattan, but by Thanksgiving he was hospitalized again. Another stint in a shelter followed in April, when his building was sold.

Finally, in July, Mr. Johnson moved to supported housing on Staten Island, where he lives with a roommate. His monthly $900 Social Security disability check is sent to the residence, which deducts $600 for rent and gives him $175 in spending money; he has breakfast and lunch at the Brooklyn agency. To assist Mr. Johnson with unexpected expenses, a grant of $550 through The New York Times Neediest Cases Fund went to buy him a bed and pay a Medicare prescription plan fee for three months.

“I was so happy I have a bed to sleep on,” he said about the replacement for an air mattress. “When I have a long day, I have a bed to lay in, and I feel good about that.”

Mr. Johnson’s goals include getting his driver’s license — “I already have a learner’s permit,” he said, proudly — finishing his program at the agency, and then entering an apprenticeship program to become a plumber, carpenter or mechanic.

But seeing how his peers have benefited from Fabulous Phil Fridays has made him vow to remain involved with people dealing with mental illnesses or substance abuse.

He was asked at the party: Might he be like the comic-book heroes he loves? A smile spread across his face. He seemed to think so.

Israel Steps Up Aerial Strikes in Gaza

Tyler Hicks/The New York Times

A man injured by bombing in the Zaitoun neighborhood of Gaza City on Saturday that also killed one person.

GAZA CITY — Israel broadened its assault on the Gaza Strip on Saturday from mostly military targets to centers of government infrastructure, obliterating the four-story headquarters of the Hamas prime minister with a barrage of five bombs before dawn.

The attack, one of several on government installations, came a day after the prime minister, Ismail Haniya, hosted his Egyptian counterpart in that very building, a sign of Hamas’s new legitimacy in a radically redrawn Arab world. That stature was underscored Saturday by a visit to Gaza from the Tunisian foreign minister and the rapid convergence in Cairo of two Hamas allies, the prime minister of Turkey and the crown prince of Qatar, for talks with the Egyptian president and the chairman of Hamas on a possible cease-fire.

But as the fighting ended its fourth day, with Israel continuing preparations for a ground invasion, the conflict showed no sign of abating. Gaza militants again fired long-range missiles at Tel Aviv, among nearly 60 that soared into Israel on Saturday. Israel said it hit more than 200 targets overnight in Gaza, and continued with afternoon strikes on the home of a Hamas commander and on a motorcycle-riding militant.

The White House reiterated its strong support for Israel, with Ben Rhodes, the deputy national security adviser, describing rocket fire from Gaza as “the precipitating factor for the conflict.”

“We believe Israel has a right to defend itself, and they’ll make their own decisions about the tactics that they use in that regard,” Mr. Rhodes told reporters on Air Force One en route to Asia.

Hamas health officials said 45 Palestinians had been killed and 385 wounded since Wednesday’s escalation in the cross-border battle. In Israel, 3 Israeli civilians have died and 63 have been injured. Four soldiers were also wounded on Saturday.

Two rockets were fired at Tel Aviv on Saturday. One landed harmlessly, probably at sea. The other was intercepted by the Iron Dome defense system in the sky above the city. An Iron Dome antimissile battery had been hastily deployed near the city on Saturday in response to the threat of longer-range rockets.

Since Wednesday, Iron Dome has knocked 245 rockets out of the sky, the military said, while 500 have struck Israel. The American-financed system is designed to intercept only rockets streaking toward towns and cities and to ignore those likely to strike open ground.

There have been failures — on Saturday a rocket crashed into an apartment block in the southern port city of Ashdod, injuring five people — but officials have put its success rate at 90 percent.

Analysts said there is no clear end to the conflict in sight, since Israel neither wants to re-engage in Gaza nor to eliminate Hamas and leave the territory to the chaos of more militant factions.

“Ultimately,” said Efraim Halevy, a former chief of Israel’s intelligence service, “both sides want Hamas to remain in control, strange as it sounds.”

But Mkhaimar Abusada, a political science professor at Al Azhar University here, cautioned that “there is no military solution to the Gaza problem.”

“There has to be a political settlement at the end of this,” he said. “Without that, this conflict is just going to go on and on.”

President Mohamed Morsi of Egypt said late Saturday night that “there could be a cease-fire soon,” after he and other members of his government spent the day in meetings with the Turkish premier, the Qatari prince, the political leaders of Hamas and other Gaza factions. But Mark Regev, a spokesman for Prime Minister Benjamin Netanyahu of Israel, denied reports that a truce was imminent.

It was unclear whether the deal under discussion would solely suspend the fighting or include other issues. Hamas — which won elections in Gaza in 2006 and took full control in 2007 but is considered a terrorist organization by Israel and the United States — wants to turn its Rafah crossing with Egypt into a free-trade zone and seeks Israel’s withdrawal from the 1,000-foot buffer it patrols on Gaza’s northern and eastern borders.

Mr. Rhodes said the Turkish and Egyptian leaders “have the ability to play a constructive role in engaging Hamas and encouraging a process of de-escalation.”

Mr. Netanyahu, for his part, spoke with the leaders of Britain, Germany, Italy, Greece, Poland, Portugal, Bulgaria and the Czech Republic, according to a statement from his office.

Jodi Rudoren reported from Gaza City, and Isabel Kershner from Jerusalem. Reporting was contributed by Fares Akram and Tyler Hicks from the Gaza Strip, Carol Sutherland and Iritz Pazner Garshowitz from Jerusalem, and David D. Kirkpatrick and Mayy El Sheikh from Cairo.

DealBook: As Labor Talks Collapse, Hostess Turns Out Lights

What might be the last Twinkie in America — at least for a while — rolled off a factory line Friday morning. It was just like the millions that had come before it, golden, cream-filled empty calories, a monument to classic American junk food.

But it is likely to be the last under the current management. After not one but two bankruptcies, Hostess Brands, the beleaguered purveyor of Twinkies, Ho Hos, Sno Balls and Wonder bread, announced plans to wind down operations and sell off its brands.

Since filing for Chapter 11 bankruptcy protection in January, Hostess has been trying to renegotiate its labor contracts in a bid to cut costs. But the talks fell apart, and last week one union went on strike.

The so-called liquidation will probably spell the end of Hostess, an 82-year-old company that has endured wars, countless diet fads and even an earlier Chapter 11 filing. Although the company could theoretically negotiate a last-minute deal with the union, Hostess is moving to shut factories and lay off a large majority of its 18,500 employees.

But Twinkies and the other well-known brands could eventually find new life under a different owner. As part of the process, Hostess is looking to auction off its assets, and suitors could find value in the portfolio.

“The potential loss of iconic brands is difficult,” said the company’s chief executive, Gregory F. Rayburn. “But it’s overshadowed by the 18,500 families that are out of work.”

The company’s current problems stem, in part, from the legacy of its past.

An amalgam of brands and businesses, the company has evolved over the years through acquisitions. In the 1960s and 1970s, the company, then called Interstate, bought more than a dozen regional bakeries scattered across the country. A couple of decades later, it paid $330 million for the Continental Baking Company, picking up a portfolio of brands like Wonder and Hostess.

As the national appetite for junk food waned, the company fell on hard times, struggling against rising labor and commodity costs. In 2004, it filed for bankruptcy for the first time.

Five years later, the company emerged from Chapter 11 as Hostess Brands, so named after its most prominent division. With America’s new health-conscious attitude, it sought to reshape the business to changing times, introducing new products like 100-calorie Twinkie Bites.

But the new private equity backers loaded the company with debt, making it difficult to invest in new equipment. Earlier this year, Hostess had more than $860 million of debt.

The labor costs, too, proved insurmountable, a situation that has been complicated by years of deal-making. The bulk of the work force belongs to 12 unions, including the International Brotherhood of Teamsters and the Bakery, Confectionery, Tobacco Workers and Grain Millers International Union.

The combination of debt and labor costs has hurt profits. The company posted revenue of $2.5 billion in the fiscal year 2011, the last available data. But it reported a net loss of $341 million.

With profits eroding, the company filed for Chapter 11 in January. It originally hoped to reorganize its finances, seeking lower labor costs, including an immediate 8 percent pay cut.

The negotiations have been contentious.

The Teamsters, which has 6,700 members at Hostess, said it played an instrumental role in ousting Hostess’s previous chief executive, Brian J. Driscoll, this year after the board tripled his compensation to $2.55 million. The union also hired a financial consultant, Harry J. Wilson, who had worked on the General Motors restructuring.

While highly critical of management missteps, the Teamsters agreed in September to major concessions, including cuts in wages and company contributions to health care. As part of the deal, the union was to receive a 25 percent share of the company’s stock and a $100 million claim in bankruptcy.

“The objective was to preserve jobs,” said Ken Hall, the Teamsters’ general secretary-treasurer. “When you have a company that’s in the financial situation that Hostess is, it’s just not possible to maintain everything you have.”

But Hostess reached an impasse with the bakery union. Frank Hurt, the union’s president, seemed to lose patience with Hostess’s management, upset that it was in bankruptcy for the second time despite $100 million in labor concessions. He saw little promise that management would turn things around.

“Our members decided they were not going to take any more abuse from a company they have given so much to for so many years,” said Mr. Hurt. “They decided that they were not going to agree to another round of outrageous wage and benefit cuts and give up their pension only to see yet another management team fail and Wall Street vulture capitalists and ‘restructuring specialists’ walk away with untold millions of dollars.”

About a month ago, Mr. Rayburn said, the bakers union stopped returning the company’s phone calls altogether. For its part, the bakery union said the company had taken an overly aggressive approach. David Durkee, the union’s secretary-treasurer, said Hostess had given an ultimatum. “They said, ‘If you do not ratify this, we are going to liquidate based on your vote.’ ”

With the company standing firm, the bakery union struck last week, affecting nearly two-thirds of the company’s factories across the country. The Teamsters drivers honored the picket line, further shutting down the operations. The company gave union members until 5 p.m. on Thursday to return to work.

Mr. Rayburn said the financial strain of the strike was too much for the company, which had already reached the limits of its bankruptcy financing. Over the last week, Hostess lost tens of millions of dollars as many customers’ orders went unfilled. And its lenders would not open their wallets one more time.

By Thursday morning, Hostess’s executives were ensconced in the company’s headquarters in Irving, Tex., still hoping that enough employees would return to work to resume production. A small number of workers had already crossed the picket lines that had sprung up at most of the baker’s factories, but more than 10 plants remained well below their necessary capacity.

Mr. Rayburn’s deadline of 5 p.m. passed without either side backing down. Soon after, executives asked the company’s legal advisers to finish the court motions that would begin the liquidation. Papers had been drawn up well before that afternoon.

Around 7 p.m., Mr. Rayburn had his final discussions with the company’s board and his senior managers and made the call to begin winding down.

“We were trying to focus on where people were having success, but I had to make a call,” Mr. Rayburn said.

N.F.L. Paid Millions Over Brain Injuries, Article Says

Three retired N.F.L. players received at least $2 million in disability payments as a result of brain trauma injuries from their playing days, according to an article by ESPN and the PBS series “Frontline.”

The payments were made in the 1990s and early 2000s by the Bell/Rozelle N.F.L. Player Retirement Plan, a committee comprising representatives of the owners, players and the N.F.L. commissioner.

The N.F.L. is being sued by several thousand retired players who accuse the league of concealing a link between head hits and brain injuries. The league denies the accusation and has said it did not mislead its players.

The article, however, cites a letter written in 2000 from the director of the retirement plan who stated that Mike Webster, who retired in 1990, had a disability that was “the result of head injuries he suffered as a football player with the Pittsburgh Steelers and the Kansas City Chiefs.”

Webster died in 2002. The article cites similar payments to Gerry Sullivan, a Browns lineman, and a third, unnamed player.

The article provides more details than were known about Webster’s case; his fight for disability benefits was known. The retired players say in their complaint that “the N.F.L.’s own physician independently examined Webster and concluded that Webster was mentally ‘completely and totally disabled as of the date of his retirement and was certainly disabled when he stopped playing football sometime in 1990.’ ”

However, Greg Aiello, an N.F.L. spokesman, said that the ESPN report “underscores that we have had a system in place with the union for many years to address player injury claims on a case-by-case basis.” The disability plan, he said, was “collectively bargained with the players.”

“All decisions concerning player injury claims are made by the disability plan’s board, not by the N.F.L. or by the Players Association,” Aiello said.

The board has seven members: three owner representatives, three player representatives and one nonvoting representative of the commissioner.

The disclosures in the article came a day after Commissioner Roger Goodell spoke at the Harvard School of Public Health, where he trumpeted the league’s efforts to increase the safety of its players and proclaimed that “medical decisions override everything else.”

Jeffrey Standen, a law professor at Willamette University in Oregon, said the details about Webster’s disability payments did not amount to a smoking gun. The plan’s determination that Webster sustained head injuries is not the same as the N.F.L. making that decision.

“The problem is the N.F.L. didn’t make the admission; it was the board,” Standen said. “They’re not the same body. As a legal matter, the fact that they paid Webster is not going to matter much in legal terms. But it’s evidence to throw in front of a jury.”
