Hobbits, superheroes put magic in NZ film industry

WELLINGTON, New Zealand (AP) — A crate full of sushi arrives. Workers wearing wetsuit shirts or in bare feet bustle past with slim laptops. With days to go, a buzzing intensity fills the once-dilapidated warehouses where Peter Jackson's visual-effects studio is rushing to finish the opening film in "The Hobbit" trilogy.

The fevered pace at the Weta Digital studio near Wellington will last nearly until the actors walk the red carpet Nov. 28 for the world premiere. But after "The Hobbit: An Unexpected Journey" hits theaters, there's more work to be done.

Weta Digital is the centerpiece of a filmmaking empire that Jackson and close collaborators have built in his New Zealand hometown, realizing his dream of bringing a slice of Hollywood to Wellington. It's a one-stop shop for making major movies — not only his own, but other blockbusters like "Avatar" and "The Avengers" and hoped-for blockbusters like next year's "Man of Steel."

Along the way, Jackson has become revered here, even receiving a knighthood. His humble demeanor and crumpled appearance appeal to distinctly New Zealand values, yet his modesty belies his influence. He's also attracted criticism along the way.

The special-effects workforce of 150 on "The Lord of the Rings" trilogy a decade ago now numbers 1,100. Only five of Weta Digital's workers are actual employees, however, while the rest are contractors. Many accept the situation because movie work often comes irregularly but pays well. Union leaders, though, say the workers lack labor protections existing in almost any other industry.

Like many colleagues, Weta Digital's director, Joe Letteri, came to New Zealand in 2001 to work on the "Rings" trilogy for two years. The work kept coming, so he bought a house in Wellington and stayed.

"People come here because they know it's their chance to do something really great and to get it up on the screen," he said in a recent interview. "And you want to do it in these next two weeks, because the two weeks after the movie's finished are useless."

Jackson, who declined to be interviewed for this story, launched Weta in 1993 with fellow filmmakers Jamie Selkirk and Richard Taylor. Named after an oversized New Zealand insect, the company later was split into its digital arm and Weta Workshop, which makes props and costumes.

Loving homages to the craft are present in Weta Digital's seven buildings around the green-hilled suburb of Miramar. There are old-time movie posters, prop skulls of dinosaurs and apes, and a wall of latex face impressions of actors from Chris O'Donnell to Tom Cruise.

Its huge data center, with the computing power of 30,000 laptops, resembles a milk-processing plant because only the dairy industry in New Zealand knew how to build cooling systems on such a grand scale.

Little of Weta's current work was visible. Visitors must sign confidentiality agreements, and the working areas of the facilities are off-limits. The company is secretive about any unannounced projects, beyond saying Weta will be working solidly for the next two years, when the two later "Hobbit" films are scheduled to be released.

The workforce has changed from majority American to about 60 percent New Zealanders. The only skill that's needed, Letteri says, is the ability to use a computer as a tool.

Beyond having creativity as a filmmaker, Jackson has proved a savvy businessman, Letteri says.

"The film business in general is volatile, and visual effects has to be sitting right on the crest of that wave," Letteri says. "We don't get asked to do something that somebody has seen before."

The government calculates that feature films contribute $560 million each year to New Zealand's economy. Like many countries, New Zealand offers incentives and rebates to film companies and will contribute about $100 million toward the $500 million production costs of "The Hobbit" trilogy. Almost every big budget film goes through Jackson's companies.

"New Zealand has a good reputation for delivering films on time and under budget, and Jackson has been superb at that," says John Yeabsley, a senior fellow at New Zealand's Institute of Economic Research. "Nobody has the same record or the magic ability to bring home the bacon as Sir Peter."

"You cannot overestimate the fact that Peter is a brand," says Graeme Mason, chief executive of the New Zealand Film Commission. "He's built this incredible reputational position, which has a snowball effect."

Back in 2010, however, a labor dispute erupted before filming began on "The Hobbit." Unions said they would boycott the movie if the actors didn't get to collectively negotiate. Jackson and others warned that New Zealand could lose the films to Europe. Warner Bros. executives flew to New Zealand and held a high-stakes meeting with Prime Minister John Key, whose government changed labor laws overnight to clarify that movie workers were exempt from being treated as regular employees.

Helen Kelly, president of the New Zealand Council of Trade Unions, says a compromise could easily have been reached. She says the law changes amounted to unnecessary union-busting and a "gross breach" of employment laws.

"I was very disappointed at Peter Jackson for lobbying for that," she says, "and I was furious at the government for doing it."

Weta Digital's general manager Tom Greally compared it to the construction industry, where multiple contractors and mobile workers do specific projects and then move on.

Animal rights activists said last week they plan to picket the premiere of "The Hobbit" after wranglers alleged that three horses and up to two dozen other animals died in unsafe conditions at a farm where animals were boarded for the movies. Jackson's spokesman Matt Dravitzki acknowledged two horses died preventable deaths at the farm but said the production company worked quickly to improve animal housing and safety. He rejected claims any animals were mistreated or abused.

Jackson's team pointed out that 55 percent of animal images in "The Hobbit" were computer generated at Weta. The People for the Ethical Treatment of Animals (PETA) have asked Jackson in the future to create all his animals in the studio.

Controversies aside, the rise of Weta and the expat American community in and around Miramar is visible in everything from a Mexican restaurant to yoga classes. On Halloween, which in the past was not much celebrated in New Zealand, hundreds of costumed children roamed about collecting candy. Americans gave the tradition a boost here, but the locals have embraced it.

The National Business Review newspaper estimates Jackson's personal fortune to be about $400 million, which could rise considerably if "The Hobbit" franchise succeeds. Public records show Jackson has partial ownership stakes in 21 private companies, most connected with his film empire. He's spent some of his money on philanthropy, helping save a historic church and a performance theater.

For all his influence, Jackson maintains a hobbit-like existence himself, preferring a quiet home life outside of work. In the end, many say, he seems to be driven by what has interested him from the start: telling great stories on the big screen.

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.

Social Security benefits: Five tips

(Bradley C Bower, Associated Press / February 10, 2005)

By Scott Wilson, Los Angeles Times

November 25, 2012

Deciding when to start collecting Social Security retirement benefits is one of the most important financial decisions Americans face. Beginning too soon — or too late — can end up costing you tens of thousands of dollars, depending on how long you live. Some key things to consider:

• You can start receiving Social Security payments at age 62, but the amount will be reduced 25% to 30% from what it would be at your "full" retirement age. If you were born in 1960 or later, your full retirement age is 67. For those born from 1943 to 1959, it's somewhere from age 66 to 66 years and 10 months. See http://www.ssa.gov/retire2/agereduction.htm.

•You may want to put off Social Security beyond your full retirement age. "You can get 32% more than your full benefit by waiting until you're 70 to begin collecting," author Jonathan Peterson wrote in "Social Security for Dummies." There's no reason, though, to wait beyond age 70 — your payments won't increase.

•Estimate your benefits. You can get a personalized estimate of your Social Security benefits, based on your lifetime earnings, by setting up an online account at http://www.ssa.gov/mystatement. A simpler but less accurate option is to use the Social Security quick calculator at http://www.ssa.gov/OACT/quickcalc/.

•Get a ballpark idea of how long you'll live by checking an online life expectancy calculator. "Also consider how old your parents lived to be and your personal health, including chronic conditions that may shorten your life span," Peterson said. Generally, the longer you expect to live, the more delaying the start of retirement benefits makes sense.

•Remember other factors. Your Social Security benefit is only one part of your financial equation. Consider your pension, 401(k), savings and medical needs, and how long you plan to keep working. Also consider your spouse's finances and the age when he or she will start receiving Social Security benefits.

Dave Roberts brings diversity to the San Diego County supervisors

DEL MAR — In January, when he joins the San Diego County Board of Supervisors, Dave Roberts will be the only Democrat among four Republicans, the first Democrat on the board in more than two decades.

He will also be the first new supervisor in 18 years. And he will be the only one who is not a graduate of San Diego State. He has three degrees from American University in Washington, D.C.

He's also gay and married to a retired Air Force master sergeant. The two are adoptive parents to five former foster children, ages 4 to 17, who call them Daddy Dave and Daddy Wally.

With Roberts' election to a district representing a portion of San Diego and several seaside communities north of the city, diversity has arrived for the Board of Supervisors, long one of the region's most homogenous governing bodies.

"I'm going to bring some unique characteristics," Roberts, 51, said with a laugh during a family outing on the beach here.

Roberts hopes to concentrate on the same issues he focused on while serving on the Solana Beach City Council, where he is currently deputy mayor: regional fire protection, expansion of the San Dieguito River Park and "sensible" growth.

Roberts is a Democrat in the style of Republican-leaning northern San Diego County: fiscally conservative. He worked as a budget analyst for the Department of Defense and as a corporate vice president for the La Jolla-based defense contractor SAIC. He was a Republican until some in the GOP took exception to a gay man working in the Pentagon.

"The Republicans wanted me to be fired," Roberts said. "That's when I changed political parties."

Some of his first experience in government came from working as a staffer to Sen. Lowell Weicker, a Republican from Connecticut. "I learned from working for Sen. Weicker that you can make change if you're in the right place," Roberts said.

In 2009, Democratic party officials encouraged Roberts to seek the party's nomination to face incumbent Brian Bilbray (R-Carlsbad) in the 50th Congressional District.

On the verge of declaring his candidacy, Roberts was alerted by social workers about two children who needed a "forever" home. He decided that the adoption process took precedence over his political career.

Now there are five children in the two-story home in Solana Beach once owned by singer Patti Page: Robert, 17; Alex, 12; Julian, 8; Joe, 5; and Natalee, 4. Three of the children have taken the last name Roberts, and two took his spouse's last name, Oliver.

"We don't like double names," Roberts said.

Roberts and Wally Oliver, 55, have been together for 14 years. They had a commitment ceremony in 1998 and married in July 2008 in the brief period when county clerks in California were allowed to issue same-sex marriage licenses.

The family may soon expand.

"Wally would like a baby," Roberts said. "We're not Jewish, but we believe in the Jewish proverb: 'If you can save one soul, you can save the world.'"

During his race against a Republican opponent, Roberts was endorsed by the retiring incumbent, Pam Slater-Price. He has also begun discussions with Supervisor Dianne Jacob, possibly the most fiscally conservative member of the board.

He also looks forward to working with Supervisor Bill Horn, an ex-Marine who supported Proposition 8, the measure to ban same-sex marriage, and has said he opposes gays in the military. "He says things from time to time that remind me of my father," Roberts said.

For all of their fiscal conservatism, the supervisors have not dabbled much in social issues in a way that might satisfy some elements in the GOP. The board took no position on Proposition 8. Health clinics in gay neighborhoods and AIDS prevention programs are funded without controversy.

Roberts may be different in another respect from his colleagues: He will not be assigning a staff member to send out his Twitter messages. He sends out his own tweets — lots of them, on topics political and personal.

Last week, among many tweets, was one announcing that he has hired his predecessor's chief-of-staff, praising him for his "broad experience, management style and network of contacts."

And the next tweet: "Took the kids out for frozen yogurt at Seaside Yogurt in Del Mar for a treat."

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.

'Dallas' star Larry Hagman dies in Texas

J.R. Ewing was a business cheat, faithless husband and bottomless well of corruption. Yet with his sparkling grin, Larry Hagman masterfully created the charmingly loathsome oil baron — and coaxed forth a Texas-size gusher of ratings — on television's long-running and hugely successful nighttime soap, "Dallas."

Although he first gained fame as nice guy Capt. Tony Nelson on the fluffy 1965-70 NBC comedy "I Dream of Jeannie," Hagman earned his greatest stardom with J.R. The CBS serial drama about the Ewing family and those in their orbit aired from April 1978 to May 1991, and broke viewing records with its "Who shot J.R.?" 1980 cliffhanger that left unclear if Hagman's character was dead.

The actor, who returned as J.R. in a new edition of "Dallas" this year, had a long history of health problems and died Friday due to complications from his battle with cancer, his family said.

"Larry was back in his beloved hometown of Dallas, re-enacting the iconic role he loved the most. Larry's family and closest friends had joined him in Dallas for the Thanksgiving holiday," the family said in the statement, which was provided to The Associated Press by Warner Bros., producer of the show.

The 81-year-old actor was surrounded by friends and family before he passed peacefully, "just as he'd wished for," the statement said.

Linda Gray, his on-screen wife and later ex-wife in the original series and the sequel, was among those with Hagman in his final moments in a Dallas hospital, said her publicist, Jeffrey Lane.

"He brought joy to everyone he knew. He was creative, generous, funny, loving and talented, and I will miss him enormously. He was an original and lived life to the fullest," the actress said.

Years before "Dallas," Hagman had gained TV fame on "I Dream of Jeannie," in which he played an astronaut whose life is disrupted when he finds a comely genie, portrayed by Barbara Eden, and takes her home to live with him.

Eden recalled late Friday shooting the series' pilot "in the frigid cold" on a Malibu beach.

"From that day, for five more years, Larry was the center of so many fun, wild and sometimes crazy times. And in retrospect, memorable moments that will remain in my heart forever," Eden said.

Hagman also starred in two short-lived sitcoms, "The Good Life" (NBC, 1971-72) and "Here We Go Again" (ABC, 1973). His film work included well-regarded performances in "The Group," ''Harry and Tonto" and "Primary Colors."

But it was Hagman's masterful portrayal of J.R. that brought him the most fame. And the "Who shot J.R.?" story twist fueled international speculation and millions of dollars in betting-parlor wagers. It also helped give the series a place in ratings history.

When the answer was revealed in a November 1980 episode, an average 41 million U.S. viewers tuned in to make "Dallas" one of the most-watched entertainment shows of all time, trailing only the "MASH" finale in 1983 with 50 million viewers.

It was J.R.'s sister-in-law, Kristin (Mary Crosby) who plugged him — he had made her pregnant, then threatened to frame her as a prostitute unless she left town — but others had equal motivation.

Hagman played Ewing as a bottomless well of corruption with a charming grin: a business cheat and a faithless husband who tried to get his alcoholic wife, Sue Ellen (Gray), institutionalized.

"I know what I want on J.R.'s tombstone," Hagman said in 1988. "It should say: 'Here lies upright citizen J.R. Ewing. This is the only deal he ever lost.'"

On Friday night, Victoria Principal, who co-starred in the original series, recalled Hagman as "bigger than life, on-screen and off. He is unforgettable, and irreplaceable, to millions of fans around the world, and in the hearts of each of us, who was lucky enough to know and love him."

Ten episodes of the new edition of "Dallas" aired this past summer and proved a hit for TNT. Filming was in progress on the sixth episode of season two, which is set to begin airing Jan. 28, the network said.

There was no immediate comment from Warner or TNT on how the series would deal with Hagman's loss.

In 2006, he did a guest shot on FX's drama series "Nip/Tuck," playing a macho business mogul. He also got new exposure in recent years with the DVD releases of "I Dream of Jeannie" and "Dallas."

The Fort Worth, Texas, native was the son of singer-actress Mary Martin, who starred in such classics as "South Pacific" and "Peter Pan." Martin was still in her teens when he was born in 1931 during her marriage to attorney Ben Hagman.

As a youngster, Hagman gained a reputation for mischief-making as he was bumped from one private school to another. He made a stab at New York theater in the early 1950s, then served in the Air Force from 1952-56 in England.

While there, he met and married young Swedish designer Maj Axelsson. The couple had two children, Preston and Heidi, and were longtime residents of the Malibu beach colony that is home to many celebrities.

Hagman returned to acting and found work in the theater and in such TV series as "The U.S. Steel Hour," ''The Defenders" and "Sea Hunt." His first continuing role was as lawyer Ed Gibson on the daytime serial "The Edge of Night" (1961-63).

He called his 2001 memoir "Hello Darlin': Tall (and Absolutely True) Tales about My Life."

"I didn't put anything in that I thought was going to hurt someone or compromise them in any way," he told The Associated Press at the time.

Hagman was diagnosed in 1992 with cirrhosis of the liver and acknowledged that he had drank heavily for years. In 1995, a malignant tumor was discovered on his liver and he underwent a transplant.

After his transplant, he became an advocate for organ donation and volunteered at a hospital to help frightened patients.

"I counsel, encourage, meet them when they come in for their operations, and after," he said in 1996. "I try to offer some solace, like 'Don't be afraid, it will be a little uncomfortable for a brief time, but you'll be OK.' "

He also was an anti-smoking activist who took part in "Great American Smoke-Out" campaigns.

Funeral plans were not immediately announced.

"I can honestly say that we've lost not just a great actor, not just a television icon, but an element of pure Americana," Eden said in her statement Friday night. "Goodbye, Larry. There was no one like you before and there will never be anyone like you again."

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.

How I Made It: Attorney Hal Rosner

The gig: Hal Rosner is a partner at San Diego's Rosner, Barry & Babbitt, one of the largest law firms in the country specializing entirely in consumer auto fraud cases. Founded by Rosner in 1985, the firm employs 10 full-time attorneys and reviews 200 to 400 potential cases a month, taking on about 10% of them. To date, Rosner has handled more than 1,000 auto fraud cases in the Golden State, winning millions of dollars for his clients. It has won him begrudging respect from the auto industry; last year the head of the California New Car Dealers Assn. said Rosner "has about every car dealer in the state scared silly."

Born to litigate: Some boys like baseball, some like comics. Rosner went in for arguing. The cake for his fifth birthday party said: "Happy Birthday Lawyer Hal." While other kids read Hardy Boys mysteries, Rosner was diving into biographies of his hero, Clarence Darrow. And when he graduated from high school in San Jose, friends wrote, "good luck suing companies" in Rosner's yearbook. So it came as a surprise to no one when, after graduating from UC Berkeley with a double major in rhetoric and economics, he enrolled in law school at the University of San Diego.

A new mentor: In law school, Rosner traded in his dreams of handling the next Scopes Monkey Trial. Under the tutelage of Bob Fellmeth, a consumer attorney known for his pioneering work with Ralph Nader in the 1960s and '70s, Rosner became captivated with the idea of representing regular folks in fights with big companies. The two were inseparable and even went into practice together, briefly, after Rosner graduated. Fellmeth helped Rosner take on his first auto case, using California's landmark 1983 lemon law. The car in question: Rosner's own.

Today, Rosner is an adjunct professor at UC San Diego and also instructs Marine Corps and Navy attorneys at Camp Pendleton on consumer protection issues. "It's upsetting that almost no law schools teach consumer law these days," Rosner said. "You can get pet law classes, but nothing for consumers."

A breakthrough: For years, Rosner ran a fairly broad practice, taking cases against banks, telephone companies and other utilities. That all went out the window about a dozen years ago, when Rosner took on Thompson vs. 10,000 RV Sales Inc., which involved improper disclosure by the dealer of trade-in value in the sale of a recreational vehicle.

In the case, Rosner dusted off the law books to try an innovative — and risky — strategy, applying California's Automotive Sales Finance Act, a decades-old statute that grants unusually large attorneys' fees and damages with a favorable verdict. If Rosner lost, it could cost him a lot of money, but if he won, he'd be opening the door to take on countless fraud cases involving sums normally too small for lawyers working on contingency to handle. Rosner prevailed. "That changed everything," he said. "It tipped me off to focus my practice on the way vehicles are financed."

At 'war': A huge portion of dealership profits — and some say shenanigans — take place in the windowless finance rooms in the back of every lot. Known as the "F&I Office" or "the box," it's where insurance policies, extended warranties and undercoat are packed into deals, and where Rosner contends that consumers can get robbed blind without realizing it if they're not careful. Few lawyers take on such cases because they're technical and the laws are arcane, but it's fertile terrain for the right lawyer. And that just happens to be Rosner's sweet spot.

"In the last decade I've been in a massive war with the auto industry when it comes to finance issues," Rosner said. "I'm willing to bet that I can find something illegal in 10% to 20% of all car sale contracts."

Making friends: Rosner's aggressive tactics haven't won him many fans among dealers. After a lengthy dispute with a San Diego area dealership over backdated sales contracts, Rosner took the same argument to court against a sister lot owned by the same company in Riverside County. That case, now on appeal, provoked the dealership's general manager to launch a website criticizing Rosner and his tactics: http://www.halrosner.com. Rosner acknowledged he should have grabbed that URL a long time ago, but shrugs off the site. "It goes with the territory," he said.

When court is not in session: The 6-foot-2 Rosner calls himself a "basketball addict" and, at 54 years old, still plays in two tournaments a year. A bruising small forward who likes a lot of contact, he said he "can still touch rim" and works out regularly with his 14-year-old son — when he isn't taking his 12-year-old daughter shopping. Rosner's other hobby is poker; the game has taught him a lot about his day job, which he said benefits from poker-style analysis of changing odds.

"Cases are like Texas hold 'em. I know what my first two cards are, but a bad card can come at any time," Rosner said. "I play poker for fun but I gamble for a living."

Lining up even earlier for Black Friday becomes a shop priority

In a tradition that seems to take a bigger slice of Thanksgiving every year, hordes of deal-sniffing shoppers descended on Southland stores Thursday, elbowing their way in search of toys, video games and that time-honored Black Friday symbol: cut-rate television sets. As nightfall came, they huddled in long lines, clutching coupons and hatching shopping strategies.

Rebecca Abbott, 42, of Torrance had it down to a science Thursday night. The accountant said she was out the door of the local Toys R Us store in 20 minutes with a shopping cart full of Christmas gifts for her two daughters. 

Her fourth time shopping on Black Friday, Abbott had spent a few hours in Toys R Us the day before scoping out her plan of attack. The first item on her list: a Rockstar Mickey Mouse doll, normally priced at $59.99 but selling for just $19.99.

"You have to have a strategy for this Black Friday madness," she said as she headed for the door. "First-timers will walk around all day looking at deals," Abbott said. "I got in, grabbed my stuff and got out." Her cart was overflowing with large toys — primarily Barbie and Mickey Mouse items.

At a Wal-Mart in Panorama City, just after 8 p.m., "it was really crazy, but you could still walk," said Marya Huaman, 23, as she left the store with her dad, her two infant sons and three bags full of Fisher-Price toys.

"No, you couldn't," scoffed her father, Edward Huaman. "I didn't see anyone fighting, but they will be soon. This is madness."

Last year, Thanksgiving night was marred by a pepper spray "shopping rage" incident at a Wal-Mart in Porter Ranch that injured at least seven people and forced employees to evacuate part of the store. One person was hospitalized.

Los Angeles Police Cmdr. Andy Smith said Thursday that the night appeared to be running smoothly across Los Angeles. "In general, I think things have gone really well," he said. "It sounds like the stores have taken proper precautions and everyone is aware of the hazards of Black Friday."

After retailers last year moved the opening bell for Black Friday sales to midnight, this year there were even more customers eager to get a jump on the traditional kickoff to the holiday shopping season. Wal-Mart, Sears and Toys R Us began rolling out their door busters at 8 p.m. on Turkey Day, followed by Target at 9 p.m. Macy's, Kohl's and Best Buy were set to open at midnight.

A handful of chains such as Kmart and Old Navy also had daytime hours on Thursday. And online merchants were touting bargains all day and night.

About 147 million shoppers are expected this all-important holiday weekend, with more logging in for online specials by Cyber Monday, according to the National Retail Federation. In all, the trade group estimated that holidays sales will rise 4.1% this year, to $586 billion.

"Though the Black Friday tradition is here to stay, there's no question that it has changed in recent years," NRF Chief Executive Matthew Shay said in a statement.

Many shoppers were perfectly content to queue up. At Best Buy electronic stores across the Southland, people waited for hours — and sometimes days — in tents before the midnight opening.

But many workers were angry about spending Turkey Day away from loved ones.

Frustrated retail employees and families have taken to creating online petitions at Change.org to beg companies not to cut into Thanksgiving dinners. More than 20 online petitions have popped up in recent weeks. Lines grew throughout the afternoon and into the evening as anxious shoppers surveyed the competition in line.

Throughout Southern California there were reports of lines wrapped around stores. In Glendale, more than 750 shoppers were lined up outside the Target at the Galleria.

For shoppers who just couldn't wait until Thursday night — much less Black Friday — some retailers opened their doors all day on Thanksgiving.

The sales weren't quite as glorious as the Black Friday specials that stores promise to roll out later. But they were pretty good nonetheless, shoppers said.

JoAnne Garcia walked into Kmart in Burbank in search of a roasting pan in which to cook her turkey. She walked out 90 minutes later, having shelled out $491, including $329 for an RCA 39-inch LCD flat-panel TV.

"The roasting pan was $14.99," Garcia said, laughing at how much she spent as she rolled her cart to the parking lot.

To the 53-year-old aerospace machinist, shopping on Thanksgiving made perfect sense.

Standing near a store display touting "Freak Out Pricing," Garcia explained her theory about shopping while cooking. "You get up, throw your turkey in the oven, and you come back and it's all done."

Halle Berry's ex arrested after fight at her house

LOS ANGELES (AP) — Halle Berry's ex-boyfriend Gabriel Aubry was arrested for investigation of battery Thursday after he and the Oscar-winning actress's current boyfriend got into a fight at her Hollywood Hills home, police said.

Aubry, 37, was booked for investigation of a battery, a misdemeanor, and released on $20,000 bail, according to online jail records. He's scheduled to appear in court Dec. 13.

Aubry came to Berry's house Thanksgiving morning and police responded to a report of an assault, said Los Angeles Police Officer Julie Boyer. Aubry was injured in the altercation and was taken to a hospital where he was treated and released.

Emails sent to Berry's publicist, Meredith O'Sullivan, and Aubry's family law attorney, Gary Fishbein, were not immediately returned.

Berry and Aubry have been involved in a custody dispute involving their 4-year-old daughter, Nahla. The proceedings were sealed because the former couple are not married. Both appeared in the case as recently as Nov. 9, but neither side commented on the outcome of the hearing.

Berry has been dating French actor Olivier Martinez, and he said earlier this year that they are engaged.
