Hard-fought victory assures Irish spot in national title game

LOS ANGELES — Deliverance arrived on a crisp southern California night, welcomed in a frenzy of leaps and hugs and arms wind-milling helmets and cathartic screams. Notre Dame waited decades for this, all right, the end to the interminable search for its long-lost promise. It just needed to climb to the top of college football to find it.

The Irish will play for a national championship in January, inextricably No. 1 and 12-0 after a 22-13 victory over USC before 93,607 witnesses Saturday night at Los Angeles Memorial Coliseum, a sparkling moment of rapture in the City of Angels. Whether Notre Dame is back maybe isn't the point right now. It's that the Irish have arrived.

"We had a dream," linebacker Manti Te'o said, "and we put in the work to make sure that dream came true."

It was a grinding, imperfect but relentless effort Saturday to get there, and maybe there couldn't be any other way. Everett Golson, the redshirt freshman quarterback, cramped up but cut loose for 217 yards passing and was mistake-free. Theo Riddick, the senior tailback who was a slot receiver at this time last year, stampeded to 146 yards and a score.

And the Heisman hopeful, Te'o, picked off another pass and helped spearhead another adrenalized, fourth-quarter goal-line stand that stomped out USC's last hope and created a save-the-date for Jan. 7. There Notre Dame will play in the BCS title game, almost assuredly against the winner of the SEC, becoming the most galvanizing foil yet to that league's dominance.

"The way it's set up, only two teams can play for a national championship," Irish coach Brian Kelly said. "It feels great that you have that opportunity."

One game now, to look upon everyone else from the summit for the first time since 1988.

"Ecstatic," Irish safety Zeke Motta said. "There's no other feeling like it that I could have ever imagined. You think about the hard work and the competing that we did in the offseason, and to witness it pay off, and to be in this position we're in right now, there's no other feeling like it."

There were other, substantially less exultant feelings swirling in the same stadium tunnel a scant four years ago. Athletic director Jack Swarbrick could laugh about that Saturday night: About being pinned against a wall to discuss the downward spiral of the Charlie Weis era then, and being cornered to talk about a head-spinning revival now.

A year after that utter demolition by USC in 2008, Swarbrick made his coaching change and brought in Kelly. He brought in his program-builder. He thought it was the perfect fit. He also thought it would take longer than this.

"I gotta tell you, I always thought it was next year," Swarbrick said. "From Day 1, I thought it was next year. So it's cool. It's cool to be ahead of schedule."

In fact, maybe the only guy not taken aback was the guy responsible for it all.

"You get this far into it, and now you start to look up and go, oh, we're 11-0 — you want to finish it off," Kelly said.

"It's easy to say well, yeah, I'm surprised. But when you go in that locker room and you're around the guys I'm around, you're not surprised. What they've done, the commitment they've made, they've done everything I've asked them to do. Everything. So it doesn't surprise me anymore."

Notre Dame had USC where it wanted the Trojans early, on-heels and tested, on the spot to demonstrate any mettle or desire at the end of a season gone wrong and going nowhere. The Irish thundered to a 10-0 first-quarter lead, first scoring on a Kyle Brindza 27-yard field goal and then a Riddick 9-yard score.

If this was the last hurdle to the BCS title game, it appeared knee-high. But USC showed it could be resolute, swiftly moving to an 11-yard Robert Woods touchdown reception to reignite some drama. From there, it was field goal after field goal after field goal for both sides, a constant thrust and parry, all the way to a Brindza 33-yarder that made it a 19-10 lead entering the fourth quarter.

"We understood that it was going to be a dogfight, and that's what it was," Te'o said.

Then Notre Dame watched in glee as USC coach Lane Kiffin began exacting self-torture. First came the pre-snap timeout that might have wiped out a touchdown catch, only to watch the ensuing pass sail out of the end zone.

And after the fifth Brindza field goal created a two-score cushion with six minutes left, the pain became excruciating. A 53-yard Marqise Lee reception after a long kickoff return set up a goal-to-go situation for the Trojans. Two pass interference penalties put them on the 1-yard line. They ran once. They ran again. They ran again. Then they threw an incomplete pass.

Notre Dame had made its stand, everyone exploding off the sideline and into celebration.

"If you have followed us all year, that's how we play," Kelly said. "We come up big defensively at some time during the game. We did that again."

All that remained were 21/2 minutes to burn. Irish fans in attendance counted down the Coliseum clock, as if it was New Year's Eve.

And then the celebration began, wild and joyous, for a date decades in the making. Players bobbed and chanted in front of the fans. Te'o grabbed Kelly in the tunnel in a spontaneous embrace, telling his coach he loved him.

Notre Dame will play for a national title. A moment so many waited for, and never saw coming.

"I haven't really grasped the whole situation," Riddick said, sitting on a table in a Coliseum tunnel. "What can I say? We're going to Miami."

M.I.T. Lab Hatches Ideas, and Companies, by the Dozens

HOW do you take particles in a test tube, or components in a tiny chip, and turn them into a $100 million company?

Dr. Robert Langer, 64, knows how. Since the 1980s, his Langer Lab at the Massachusetts Institute of Technology has spun out companies whose products treat cancer, diabetes, heart disease and schizophrenia, among other diseases, and even thicken hair.

The Langer Lab is on the front lines of turning discoveries made in the lab into a range of drugs and drug delivery systems. Without this kind of technology transfer, the thinking goes, scientific discoveries might well sit on the shelf, stifling innovation.

A chemical engineer by training, Dr. Langer has helped start 25 companies and has 811 patents, issued or pending, to his name. That’s not too far behind Thomas Edison, who had 1,093. More than 250 companies have licensed or sublicensed Langer Lab patents.

Polaris Venture Partners, a Boston venture capital firm, has invested $220 million in 18 Langer Lab-inspired businesses. Combined, these businesses have improved the health of many millions of people, says Terry McGuire, co-founder of Polaris.

Along the way, Dr. Langer and his lab, including about 60 postdoctoral and graduate students at a time, have found a way to navigate some slippery territory: the intersection of academic research and the commercial market.

Over the last 30 years, many universities — including M.I.T. — have set up licensing offices that oversee the transfer of scientific discoveries to companies. These offices have become a major pathway for universities seeking to put their research to practical use, not to mention add to their revenue streams.

In the sciences in particular, technology transfer has become a key way to bring drugs and other treatments to market. “The model of biomedical innovation relies on research coming out of universities, often funded by public money,” says Josephine Johnston, director of research at the Hastings Center, a bioethics research organization based in Garrison, N.Y.

Just a few of the products that have emerged from the Langer Lab are a small wafer that delivers a dose of chemotherapy used to treat brain cancer; sugar-sequencing tools that can be used to create new drugs like safer and more effective blood thinners; and a miniaturized chip (a form of nanotechnology) that can test for diseases.

The chemotherapy wafer, called the Gliadel, is licensed by Eisai Inc. The company behind the sugar-sequencing tools, Momenta Pharmaceuticals, raised $28.4 million in an initial public offering in 2004. The miniaturized chip is made by T2Biosystems,  which completed a $23 million round of financing in the summer of 2011.

“It’s inconvenient to have to send things to a lab,” so the company is trying to develop more sophisticated methods, says Dr. Ralph Weissleder, a co-founder, with Dr. Langer and others, of T2Biosystems and a professor at Harvard Medical School.

FOR Dr. Langer, starting a company is not the same as it was, say, for Mark Zuckerberg with Facebook. “Bob is not consumed with any one company,” says H. Kent Bowen, an emeritus professor of business administration at Harvard Business School who wrote a case study on the Langer Lab. “His mission is to create the idea.”

Dr. Bowen observes that there are many other academic laboratories, including highly productive ones, but that the Langer Lab’s combination of people, spun-out companies and publications sets it apart. He says Dr. Langer “walks into the great unknown and then makes these discoveries.”

Dr. Langer is well known for his mentoring abilities. He is “notorious for replying to e-mail in two minutes, whether it’s a lowly graduate school student or the president of the United States,” says Paulina Hill, who worked in his lab from 2009 to 2011 and is now a senior associate at Polaris Venture Partners. (According to Dr. Langer, he has corresponded directly with President Obama about stem cell research and federal funds for the sciences.)

Dr. Langer says he looks at his students “as an extended family,” adding that “I really want them to do well.”

And they have, whether in business or in academia, or a combination of the two. One former student, Ram Sasisekharan, helped found Momenta and now runs his own lab at M.I.T. Ganesh Venkataraman Kaundinya is Momenta’s chief scientific officer and senior vice president for research.

Hongming Chen is vice president of research at Kala Pharmaceuticals. Howard Bernstein is chief scientific officer at Seventh Sense Biosystems, a blood-testing company. Still others have taken jobs in the law or in government.

Dr. Langer says he spends about eight hours a week working on companies that come out of his lab. Of the 25 that he helped start, he serves on the boards of 12 and is an informal adviser to 4. All of his entrepreneurial activity, which includes some equity stakes, has made him a millionaire. But he says he is mainly motivated by a desire to improve people’s health.

Operating from the sixth floor of the David H. Koch Institute for Integrative Cancer Research on the M.I.T. campus in Cambridge, Mass., Dr. Langer’s lab has a research budget of more than $10 million for 2012, coming mostly from federal sources.

The research in labs like Dr. Langer’s is eyed closely by pharmaceutical companies. While drug companies employ huge research and development teams, they may not be as freewheeling and nimble, Dr. Langer says. The basis for many long-range discoveries has “come out of academia, including gene therapy, gene sequencing and tissue engineering,” he says.

He has served as a consultant to pharmaceutical companies. Their large size, he says, can end up being an impediment.

“Very often when you are going for real innovation,” he says, “you have to go against prevailing wisdom, and it’s hard to go against prevailing wisdom when there are people who have been there for a long time and you have some vice president who says, ‘No, that doesn’t make sense.’ ”

Pharmaceutical companies are eager to tap into the talent at leading research universities. In 2008, for example, Washington University in St. Louis announced a $25 million pact with Pfizer to collaborate more closely on biomedical research.

But in some situations, the close — critics might say cozy — ties between business and academia have the potential to create conflicts of interest.

There was a controversy earlier this year when it was revealed that the president of the University of Texas M.D. Anderson Cancer Center owned stock in Aveo Oncology, which had announced earlier that the university would be leading clinical trials of one of its cancer drugs.  Last month, the University of Texas announced that he would be allowed to keep his ties with three pharmaceutical companies, including Aveo Oncology; his holdings will be placed in a blind trust.

Rosenthal: Big Ten getting too big for its own good?

There's a lesson the empire builders at Big Ten Conference headquarters in Park Ridge would do well to heed if they can be convinced to stop peering out to the distant horizon:

Growth through acquisition is fraught with peril.

"In the business world you acquire new companies and you have to deal with different corporate cultures, different priorities and so forth," Robert Arnott, chairman of Research Affiliates LLC, an investment firm, said in an interview. "Merging them is often very messy and often fails. Here you're merging two teams into an existing conference and it creates risks. … Even college football teams have different cultures, different ways of thinking about how to win and different standards."

There undoubtedly was a logic behind each acquisition as the old Sears sought to expand and diversify its corporate profile. By the time the Chicago-area company's portfolio grew to include Allstate insurance, Coldwell Banker real estate and Dean Witter Reynolds stock brokerage, it was clear the increase in size was in no way matched by an increase in strength.

Rather than an all-powerful Colossus astride many sectors at once, it was reduced to an unfocused blob, bereft of identity, covering plenty of ground but hardly standing tall. Years after shedding its far-flung holdings, Sears has yet to regain its muscle, mojo or market share.

"It's hard to find a better example of a company that lost its mission and focus in the quest for growth," Arnott said.

"(Growth) may be partly a defensive move. It may be ego driven. In the corporate arena, you certainly see that in spades," he said. "When growth is through acquisition, you have to figure out what the real motivation is. Is it synergy, the most overused word in the finance community, or is it ego?"

Adding the University of Maryland and New Jersey's Rutgers University in 2014 will push the Big Ten to 14 schools and far beyond the Midwestern territory for which it's known. But doing so may not achieve what its backers envision.

Rather than spread the conference's brand, it may merely dilute it. The fit may be corrosive, not cohesive.

There is a school of thought that this is but the latest evidence that the Big Ten is not about athletics, academics or even the Midwest. Instead, it is just a television network, the schools content providers and student-athletes talent.

As it is, the overall TV payout is said to give each of the 12 current Big Ten schools about $21 million per year. They point to the Big Ten's lucrative deals with ESPN and its own eponymous cable network, a partnership with News Corp. They note that public schools Rutgers and Maryland are near enough to New York, Baltimore and Washington, D.C., to drive a better bargain with cable carriers.

To Big Ten Commissioner Jim Delany, a New Jersey native, the addition is more the result of a paradigm shift that has redrawn the college sports map over the past decade. Some conferences splinter. Others seize new turf. The result: Idaho's Boise State football team is poised to join the Big East Conference next year.

"Institutions that get together for academics or athletics have got to be cognizant that they are competing for students, they are competing for student athletes, they are competing for research dollars," Delany told reporters.

"When you see a Southern conference in the Midwest or you see a Southern conference in the Plains states or whether you see other conferences in the Midwest or Northeast, it impacts your recruitment. ... It impacts everything you do," he said. "At a certain point you get to a tipping point. The paradigm has shifted, and you decide on a strategy to basically position yourself for the next decade or half-century."

Big has always meant more than 10 in the Big Ten, an intercollegiate entity formed by seven Midwestern universities that now boasts 12 with the bookends of Penn State and Nebraska added in 1990 and last year, respectively. Last week's announcement of adding schools 13 and 14 was just a reminder that the conference has only had 10 member schools for 70 of its 116 years and won't again for the foreseeable future.

Rutgers President Robert Barchi said his school looked "forward as much to the collaboration and interaction we're going to have as institutions as we do to what I know will be really outstanding competition on our field of play."

But make no mistake, the Big Ten was born out of sports, specifically football. A seven-school 1896 meeting at Chicago's Palmer House had Northwestern among those still stinging from a scathing Harper's Weekly critique of college sports abuses, the Tribune reported at the time.

A prohibition on allowing scholarship and fellowship students to compete was shot down. But "a move towards the coordination of Faculty committees" in terms of standards and enforcement passed and the precursor to the Big Ten was born.

Along the way, the conference has added member schools and come to recognize that the Big Ten's image has much to say about how those institutions are perceived. Scandals already are no stranger to the Big Ten. But whether you play in a stadium or on Wall Street, the bigger one gets, the bigger target one becomes.

"Whoever's biggest draws scrutiny," said Arnott, co-author of a research paper, "The Winners Curse: Too Big to Succeed." "That means politicians, regulators, the general public generally don't root for the biggest. They look to take them down a notch, so it's harder to succeed as the largest. It's also harder to move the dial and move from success to success as you get really big."

Everyone talks about becoming too big to fail, but there's also too big to scale, companies that are unable to capitalize on the efficiencies of their increased size ostensibly because they are so big that they cannot be managed adequately.

"People talk about economies of scale. There are also vast diseconomies of scale, mostly in bureaucracies," Arnott said. "The more people you have involved, the more people you have who feel they have to have their views reflected in whatever's done. So you wind up with innovation by committee."

That's deadly. That's why companies break up, citing the need to get smaller so they can grow.

"If you break up companies into operating entities that are more nimble," Arnott said, "the opportunities to grow are no longer hamstrung by centralized bureaucracies that have to pursue synergies that don't exist."

Size matters in all fields of play. Sometimes smaller is better.

Larry Hagman dies at 81; TV's J.R. Ewing

Fervor for the television show “Dallas” was intense in 1980, when the Queen Mother met actor Larry Hagman and joined the worldwide chorus asking: “Who shot J.R.?”

“Not even for you, ma’am,” replied Hagman, who portrayed villainous oil baron J.R. Ewing at the center of the popular prime-time soap from 1978 until 1991.

An estimated 300 million viewers in 57 countries had seen J.R. get shot by an unseen assailant, a season-ending plot twist that is credited with popularizing the cliffhanger in television series.

Hagman, who became a television star in the 1960s starring in the sitcom “I Dream of Jeannie,” died Friday at a Dallas hospital, said a spokesman for actress Linda Gray, his longtime co-star on “Dallas.” He was 81.

A year ago, Hagman announced his second bout with cancer. He had spoken candidly about decades of drinking that led to cirrhosis of the liver and, in 1995, a life-saving liver transplant.

“He was the pied piper of life and brought joy to everyone he knew,” Gray said in a statement. “He was creative, generous, funny, loving and talented.... an original and lived life to the full.”

For years, he was considered the unofficial mayor of Malibu, where he lived for decades in an oceanfront home. He often led impromptu ragtag parades on the sand while wearing outlandish costumes and flew a flag from his deck that declared “Vita Celebratio Est” — “Life is a celebration.”

As an actor, Hagman came with a serious pedigree. He was the son of Mary Martin, a legendary star of Broadway musicals best known for originating the role of Peter Pan in the 1950s.

On “Dallas,” Hagman's J.R. Ewing was “the man viewers loved to hate,” according to critics, a scheming Texan in a land of plenty. Much of the show's run paralleled the nation's fascination with big money and big business in the 1980s, and the role made him an international star.

“Here is a man born to play villainy,” former Times TV critic Howard Rosenberg wrote soon after the show's debut. “His performance on ‘Dallas’ is a salute to slime.”

A Texas native, Hagman often said he played the character as a composite of “all those good old boys” he had known growing up, “who caught more flies with honey instead of vinegar.”

He approached the role as “a cartoon,” Hagman once said of the role that earned him two Emmy nominations. “It was outrageous comedy to me.”

By his own admission, Hagman drank his way through “Dallas.” Champagne was “his poison” — he would uncork a bottle by 9 a.m. and keep the bubbly flowing all day. He once poured bourbon on his cornflakes.

“The drinking sometimes made it harder to remember lines, but I liked that constant feeling of being mildly loaded,” Hagman said in 1995 in People magazine.

Diagnosed with cirrhosis of the liver during a checkup in 1992, Hagman said he became an instant teetotaler. After developing a cancerous tumor on his liver, he underwent a liver transplant three years later.

“I'm often asked how my liver transplant operation changed my life. Aside from saving it, nothing changed,” he wrote in his 2001 autobiography, “Hello Darlin’.” “It confirmed what I've always tried to do — live my life as fully as possible before the clock runs out.”

When Hagman arrived in Hollywood in the 1960s, he had already appeared in a half-dozen Broadway plays and spent two years on the daytime television soap opera “The Edge of Night.”

From five television pilots, Hagman chose to read for the part of astronaut Tony Nelson on “I Dream of Jeannie.” Created by Sidney Sheldon, the show plugged into the nation’s space mania and owed a creative debt to another hit series, “Bewitched.”

Jeannie was played by Barbara Eden, who complicates the life of uptight Nelson after he aborts a mission on a desert island and unleashes her character — a magical and alluring genie — from a bottle.

Secret message found with carrier pigeon may never be deciphered

British man finds carrier pigeon skeleton in his fireplace with unbreakable secret code (Reuters)

Before military forces had secure cell phones and satellite communications, they used carrier pigeons. The highly trained birds delivered sensitive information from one location to another during  World War II. Often, the birds found the intended recipient. But not always.

A dead pigeon was recently discovered inside a chimney in Surrey, England. There for roughly 70 years, the bird had a curious canister attached to its leg. Inside was a coded message that has stumped the experts.

The code features a series of 27 groups of five letters. According to Reuters, nobody from Britain’s Government Communications Headquarters has been able to decipher it. The message was sent by a Sgt. W. Scott to someone or something identified as “Xo2.”

A spokesperson remarked, “Although it is disappointing that we cannot yet read the message brought back by a brave carrier pigeon, it is a tribute to the skills of the wartime code-makers that, despite working under severe pressure, they devised a code that was indecipherable both then and now.”

The bird was discovered by a homeowner doing renovations earlier this month. In an interview with Reuters, David Martin remarked that bits of birds kept falling from the chimney. Eventually, Margin saw the red canister and speculated that it might contain a secret message. And it seems as if the message will always be secret.

Carrier pigeons played a vital role in wars due to their incredible homing skills. All told, U.K. forces used about 250,000 of the birds during World War II.

Larry Hagman dead at 81, portrayed notorious TV villain J.R. Ewing

(Reuters) – Larry Hagman, who created one of American television’s most supreme villains in the conniving, amoral oilman J.R. Ewing of “Dallas,” died on Friday, the Dallas Morning News reported. He was 81.

Hagman died at a Dallas hospital of complications from his battle with throat cancer, the newspaper said, quoting a statement from his family. He had suffered from liver cancer and cirrhosis of the liver in the 1990s after decades of drinking.

Hagman’s mother was stage and movie star Mary Martin and he became a star himself in 1965 on “I Dream of Jeannie,” a popular television sitcom in which he played Major Anthony Nelson, an astronaut who discovers a beautiful genie in a bottle.

“Dallas,” which made its premiere on the CBS network in 1978, made Hagman a superstar. The show quickly became one of the network’s top-rated programs, built an international following and inspired a spin-off, imitators and a revival in 2012.

“Dallas” was the night-time soap-opera story of a Texas family, fabulously wealthy from oil and cattle, and its plot brimmed with back-stabbing, double-dealing, family feuds, violence, adultery and other bad behavior.

In the middle of it all stood Hagman’s black-hearted J.R. Ewing – grinning wickedly in a broad cowboy hat and boots, plotting how to cheat his business competitors and cheat on his wife. He was the villain TV viewers loved to despise during the show’s 356-episode run from 1978 to 1991.

“I really can’t remember half of the people I’ve slept with, stabbed in the back or driven to suicide,” Hagman said of his character in Time magazine.

In his autobiography, “Hello Darlin’: Tall (and Absolutely True) Tales About My Life,” Hagman wrote that J.R. originally was not to be the focus of “Dallas” but that changed when he began ad-libbing on the set to make his character more outrageous and compelling.

‘WHO SHOT J.R.?’

To conclude its second season, the “Dallas” producers put together one of U.S. television’s most memorable episodes in which Ewing was shot by an unseen assailant. That gave fans months to fret over whether J.R. would survive and who had pulled the trigger. In the show’s opening the following season, it was revealed that J.R.’s sister-in-law, Kristin, with whom he had been having an affair, was behind the gun.

Hagman said an international publisher offered him $ 250,000 to reveal who had shot J.R. and he considered giving the wrong information and taking the money, but in the end, “I decided not to be so like J.R. in real life.”

The popularity of “Dallas” made Hagman one of the best-paid actors in television and earned him a fortune that even a Ewing would have coveted. He lost some of it, however, in bad oil investments before turning to real estate.

“I have an apartment in New York, a ranch in Santa Fe, a castle in Ojai outside of L.A., a beach house in Malibu and thinking of buying a place in Santa Monica,” Hagman said in a Chicago Tribune interview.

An updated “Dallas” series began in June 2012 on the TNT network with Hagman reprising his J.R. role with original cast members Linda Gray, who played J.R.’s long-suffering wife, Sue Ellen, and Patrick Duffy, who was his brother Bobby. The show was to focus on the sons of J.R. and Bobby.

Hagman had a wide eccentric streak. When he first met actress Lauren Bacall, he licked her arm because he had been told she did not like to be touched and he was known for leading parades on the Malibu beach and showing up at a grocery store in a gorilla suit. Above his Malibu home flew a flag with the credo “Vita Celebratio Est (Life Is a Celebration)” and he lived hard for many years.

In 1967, rock musician David Crosby turned him on to LSD, which Hagman said took away his fear of death, and Jack Nicholson introduced him to marijuana because Nicholson thought he was drinking too much.

Hagman had started drinking as a teenager and said he did not stop until the moment in 1992 when his doctor told him he had cirrhosis of the liver and could die within six months. Hagman wrote that for the past 15 years he had been drinking about four bottles of champagne a day, including while on the “Dallas” set.

LIVER TRANSPLANT

In July 1995, he was diagnosed with liver cancer, which led him to quit smoking, and a month later he underwent a liver transplant.

After giving up his vices, Hagman said he did not lose his zest for life.

“It’s the same old Larry Hagman,” he told a reporter. “He’s just a littler sober-er.”

Hagman was born on September 21, 1931, in Weatherford, Texas, and his father was a lawyer who dealt with the Texas oil barons Hagman would later come to portray. He was still a boy when his parents divorced and he went to Los Angeles with Martin, who would become a Broadway and Hollywood musical star.

Hagman eventually landed in New York to pursue acting, making his stage debut there in “The Taming of the Shrew.” In New York, he married Maj Axelsson in 1954 while they were in a production of “South Pacific. The marriage produced two children, Heidi and Preston.

Hagman served in the Air Force, spending five years in Europe as the director of USO shows, and on his return to New York he took a starring role in the daytime soap “The Edge of Night.” His breakthrough came in 1965 when he landed the “I Dream of Jeannie” role opposite Barbara Eden.

In his later years, Hagman became an advocate for organ transplants and an anti-smoking campaigner. He also was devoted to solar energy, telling the New York Times he had a $ 750,000 solar panel system at his Ojai estate, and made a commercial in which he portrayed a J.R. Ewing who had forsaken oil for solar power. He was a longtime member of the Peace and Freedom Party, a minor leftist organization in California.

Hagman told the Times that after death he wanted his remains to be “spread over a field and have marijuana and wheat planted and harvest it in a couple of years and then have a big marijuana cake, enough for 200 to 300 people. People would eat a little of Larry.”

Scientists See Advances in Deep Learning, a Part of Artificial Intelligence

Hao Zhang/The New York Times

A voice recognition program translated a speech given by Richard F. Rashid, Microsoft’s top scientist, into Mandarin Chinese.

Using an artificial intelligence technique inspired by theories about how the brain recognizes patterns, technology companies are reporting startling gains in fields as diverse as computer vision, speech recognition and the identification of promising new molecules for designing drugs.

The advances have led to widespread enthusiasm among researchers who design software to perform human activities like seeing, listening and thinking. They offer the promise of machines that converse with humans and perform tasks like driving cars and working in factories, raising the specter of automated robots that could replace human workers.

The technology, called deep learning, has already been put to use in services like Apple’s Siri virtual personal assistant, which is based on Nuance Communications’ speech recognition service, and in Google’s Street View, which uses machine vision to identify specific addresses.

But what is new in recent months is the growing speed and accuracy of deep-learning programs, often called artificial neural networks or just “neural nets” for their resemblance to the neural connections in the brain.

“There has been a number of stunning new results with deep-learning methods,” said Yann LeCun, a computer scientist at New York University who did pioneering research in handwriting recognition at Bell Laboratories. “The kind of jump we are seeing in the accuracy of these systems is very rare indeed.”

Artificial intelligence researchers are acutely aware of the dangers of being overly optimistic. Their field has long been plagued by outbursts of misplaced enthusiasm followed by equally striking declines.

In the 1960s, some computer scientists believed that a workable artificial intelligence system was just 10 years away. In the 1980s, a wave of commercial start-ups collapsed, leading to what some people called the “A.I. winter.”

But recent achievements have impressed a wide spectrum of computer experts. In October, for example, a team of graduate students studying with the University of Toronto computer scientist Geoffrey E. Hinton won the top prize in a contest sponsored by Merck to design software to help find molecules that might lead to new drugs.

From a data set describing the chemical structure of 15 different molecules, they used deep-learning software to determine which molecule was most likely to be an effective drug agent.

The achievement was particularly impressive because the team decided to enter the contest at the last minute and designed its software with no specific knowledge about how the molecules bind to their targets. The students were also working with a relatively small set of data; neural nets typically perform well only with very large ones.

“This is a really breathtaking result because it is the first time that deep learning won, and more significantly it won on a data set that it wouldn’t have been expected to win at,” said Anthony Goldbloom, chief executive and founder of Kaggle, a company that organizes data science competitions, including the Merck contest.

Advances in pattern recognition hold implications not just for drug development but for an array of applications, including marketing and law enforcement. With greater accuracy, for example, marketers can comb large databases of consumer behavior to get more precise information on buying habits. And improvements in facial recognition are likely to make surveillance technology cheaper and more commonplace.

Artificial neural networks, an idea going back to the 1950s, seek to mimic the way the brain absorbs information and learns from it. In recent decades, Dr. Hinton, 64 (a great-great-grandson of the 19th-century mathematician George Boole, whose work in logic is the foundation for modern digital computers), has pioneered powerful new techniques for helping the artificial networks recognize patterns.

Modern artificial neural networks are composed of an array of software components, divided into inputs, hidden layers and outputs. The arrays can be “trained” by repeated exposures to recognize patterns like images or sounds.

These techniques, aided by the growing speed and power of modern computers, have led to rapid improvements in speech recognition, drug discovery and computer vision.

Deep-learning systems have recently outperformed humans in certain limited recognition tests.

Last year, for example, a program created by scientists at the Swiss A. I. Lab at the University of Lugano won a pattern recognition contest by outperforming both competing software systems and a human expert in identifying images in a database of German traffic signs.

The winning program accurately identified 99.46 percent of the images in a set of 50,000; the top score in a group of 32 human participants was 99.22 percent, and the average for the humans was 98.84 percent.

Walmart protests draw crowds, shoppers largely unfazed

Dozens of local workers, and hundreds nationally, took advantage of Black Friday crowds and camera crews at major retailers like Walmart to call for wage increases.

But there was little evidence that the chanting disrupted holiday shoppers.

Steven Restivo, a spokesman for Wal-Mart Stores, said the chain had done its "best Black Friday event ever" despite protests organized by the United Food and Commercial Workers International Union in Chicago and other cities.

At a Walmart in Chicago's Chatham neighborhood on the south side, only one of the store's 500 employees took part in the demonstration, the Bentonville, Ark.-based retailer said. "Almost all the folks you'll see protesting today are not Walmart associates," Restivo said. "I guess you can't believe everything you read in a union press release."

According to the union, protests took place in Miami and Washington, D.C., with additional events planned at Midwestern and Southern stores.

Walmart has so far avoided a union presence, which has become cumbersome for competitors like Jewel-Osco and Dominick's Finer Foods. Those chains have been closing stores as Walmart has expanded locally.

Separately Friday, dozens of members of the Workers Organizing Committee of Chicago and its supporters marched from the Loop to the Magnificent Mile to demand a $15 minimum wage and union contracts for downtown workers. Organized on November 15, the union has about 150 members and has received financial support from Service Employees International Union, Action Now and Stand Up Chicago.

Deborah Sims, marching Friday, said she worked at Macy's for 12 years, eventually making $13 an hour, before losing her job during the recession. She was rehired last holiday season, but at $8.50 an hour, with no benefits.

Sims said she expects retailers to turn to younger, less-experienced workers because "$8.25 an hour is going to look good to them."

Macy's did not respond to a request for comment.

Peter Gill, a spokesman for the Illinois Retail Merchants Association, called the demand for a $15 minimum wage dangerous "because people are out looking for jobs and it's tough in this economy."

He explained that if retailers were forced to nearly double the starting hourly wage, "you're going to have to cut the number of employees."
