Future science: Using 3D worlds to visualize data

CHICAGO (AP) — Take a walk through a human brain? Fly over the surface of Mars? Computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality with a wraparound virtual world where a researcher wearing 3D glasses can do all that and more.

In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, conveying a dizzying sense of being able to touch what's not really there.

As far back as 1950, sci-fi author Ray Bradbury imagined a children's nursery that could make bedtime stories disturbingly real. "Star Trek" fans might remember the holodeck as the virtual playground where the fictional Enterprise crew relaxed in fantasy worlds.

The Illinois computer scientists have more serious matters in mind when they hand visitors 3D glasses and a controller called a "wand." Scientists in many fields today share a common challenge: How to truly understand overwhelming amounts of data. Jason Leigh, co-inventor of the CAVE2 virtual reality system, believes this technology answers that challenge.

"In the next five years, we anticipate using the CAVE to look at really large-scale data to help scientists make sense of that information. CAVEs are essentially fantastic lenses for bringing data into focus," Leigh said.

The CAVE2 virtual world could change the way doctors are trained and improve patient care, Leigh said. Pharmaceutical researchers could use it to model the way new drugs bind to proteins in the human body. Car designers could virtually "drive" their new vehicle designs.

Imagine turning massive amounts of data — the forces behind a hurricane, for example — into a simulation that a weather researcher could enlarge and explore from the inside. Architects could walk through their skyscrapers before they are built. Surgeons could rehearse a procedure using data from an individual patient.

But the size and expense of room-based virtual reality systems may prove insurmountable barriers to widespread use, said Henry Fuchs, a computer science professor at the University of North Carolina at Chapel Hill, who is familiar with the CAVE technology but wasn't involved in its development.

While he calls the CAVE2 "a national treasure," Fuchs predicts a smaller technology such as Google's Internet-connected eyeglasses will do more to revolutionize medicine than the CAVE. Still, he says large displays are the best way today for people to interact and collaborate.

Believers include the people at Marshalltown, Iowa-based Mechdyne Corp., which has licensed the CAVE2 technology for three years and plans to market it to hospitals, the military and in the oil and gas industry, said Kurt Hoffmeister of Mechdyne.

In Chicago, researchers and graduate students are creating virtual scenarios for testing in the CAVE2. The Mars flyover is created from real NASA data. The brain tour is based on the layout of blood vessels in a real patient.

Brain surgeon Ali Alaraj remembered the first time he viewed the brain using the CAVE2.

"You can walk between the blood vessels," said the University of Illinois College of Medicine neurosurgeon. "You can look at the arteries from below. You can look at the arteries from the side.... That was science fiction for me."

Would doctors process information faster with fewer errors using CAVE2? That's the question behind a proposed study that would compare CAVE2 to conventional methods of detecting brain aneurysms and determining proper treatment, said Andreas Linninger, UIC professor of bioengineering, chemical engineering and computer science.

But it's not all serious business at the lab.

In his spare time during the past two years, research assistant Arthur Nishimoto has been programming the CAVE2 computer with the specifications for the fictional Starship Enterprise. He now can walk around his life-size recreation of the TV spacecraft.

The original technology, introduced in the early 1990s, was called CAVE, which stood for Cave Automatic Virtual Environment and also cleverly referred to Plato's cave, the philosopher's analogy about shadows and reality. It was named by former lab co-directors Tom DeFanti and Dan Sandin.

The second generation of the CAVE, invented by Leigh and his collaborator Andy Johnson, has higher resolution. The project was funded by the National Science Foundation and the Department of Energy.

"It's fantastic to come to work. Every day is like getting to live a science fiction dream," Leigh said. "To do science in this kind of environment is absolutely amazing."

L.A. Regional Food Bank is thriving at 40

David Navarro drove south from the Los Angeles Boys & Girls Club in Lincoln Heights on a recent sun-drenched day, headed to his weekly destination in a dust-gray Ford pickup.

As usual, he couldn't simply cruise into the crowded parking lot of the Los Angeles Regional Food Bank on 41st Street near Alameda. He was stopped by an employee who works miracles in the lot, arranging rigs in jigsaw patterns as drivers wait their turn to make food pickups.

The Salvation Army was already there, along with the Good News Central Church and the Episcopal Diocese of Los Angeles. Hollywood West Tenant Action Council was pulling in behind Navarro.

"I'll go in now and see what they have today," said Navarro, who told me that back at the Boys & Girls Club, people would be lining up for whatever he brought back.

Once inside the sprawling warehouse, Navarro moved as if he was in a race, trying to get his hands on as many perishables as he could before other drivers claimed them.

"They like any nice vegetables like this," he said, hoisting several crates of firm, stout zucchini onto his pushcart.

Over the course of an hour, Navarro worked up a sweat gathering boxes of bread and mounds of bananas, apples, lettuce and tomatoes. All of this tipped the scales at 556 pounds, and Navarro pushed the teetering cargo outside and loaded it onto his truck.

I thought he was done, but no.

"Now I go back," he said, "and fill the cart again."

In a region of staggering abundance, there is still desperate need. In a culture that wastes tons of food, there is still considerable hunger. And no charitable organization does more to balance the scales than the food bank, which began exactly 40 years ago, on Feb. 20, 1973.

It all began with a Pasadena cook named Tony Collier, who hated seeing perfectly good food getting thrown out at the recovery center where he worked. He began redistributing it to those in need, and the operation just kept growing. Today, it distributes some 200,000 pounds of food daily. A staff of 106 is backed up by 32,000 volunteers who pitch in at least one day a year, sorting food that includes non-perishables such as canned corn, as well as foods such as navel oranges and frozen chicken that have to be turned around quickly, before they go bad.

Each morning, a convoy of food bank trucks retrieves surplus food from farms, supermarket chains and other donors and brings it back to the warehouse, where it is picked up by about 650 agencies. Another 600 groups are on a waiting list to be included in the daily giveaway.

"Four hundred thousand of the 1 million people we serve each year are kids," said Michael Flood, president and chief executive of the food bank.

The challenge of the food bank has been to hook up with farmers whose harvest is sometimes bigger than the demand, or with supermarkets that have stocked more perishable food than they can sell. Ralphs and Vons are among the biggest donors to the food bank.

Still, billions of dollars worth of food ends up in dumpsters every year in the U.S., Flood said. He encourages citizens to be more conscious of waste and get involved in food donations or volunteering at a local pantry or the food bank (for more information, http://www.lafoodbank.org).

If you do happen to wander into the food bank, watch your step or you could get run over by a forklift. They zip around like bumper cars, honking horns as they wheel hulking loads toward the exits. And one of the employees who supervises the flow from delivery trucks to conveyor belts to palates is Valerie Rodriguez.

Rodriguez, like the food she processes, didn't get where she was supposed to go on the first try. The food bank is her second chance. As a teen growing up in South El Monte, she got it all wrong, becoming a drug addict, getting married way too young, losing kids she couldn't care for, and ending up in rehab at several skid row agencies, including the L.A. Mission and Union Rescue Mission.

But then she began straightening herself out, and as part of a welfare-to-work program, Rodriguez was assigned to volunteer at the food bank, not knowing anything about it. That's when she saw the trucks roll in from the missions and made the connection:

The food she'd eaten at the missions came from the food bank. She'd gone from recipient to supplier. And the food bank liked her so much that she was offered a temp job.

"It was after about a year of volunteering here," Rodriguez said.

Later, she was promoted to full time, and she's since remarried and regained custody of her children.

"It's still a struggle," she said. "But my hope and dream and desire is to save and buy a home. I want to have a home for my kids to grow up in."

While Rodriguez supervised volunteers, David Navarro finished loading his pickup and drove north from the food bank with more than 1,000 pounds of food. That evening, volunteers bagged the goods as men and women inched closer to the door of the Boys & Girls Club, eagerly awaiting their care packages.

Jo Ellen Kitchen, a volunteer at the club since the 1980s, told me she'd heard that the country has started to see an economic recovery.

"But it never really seems to get here."

It was Valentine's Day, and 20 people were in line. As dusk drew in around them, Alvina Rodriguez and Teresa Olmeda talked about the challenges of temporary work, low pay and hungry children. On this night, they and the others would go home with dinner because a simple act of compassion 40 years ago keeps rippling across the city.

IHT Rendezvous: As Europe Moves to Cap Bonuses, Britain Hesitates

LONDON — It is hard to imagine any European politician losing votes these days by promising to curb bankers’ pay, which may explain why members of the European Parliament are enthusiastically pushing for the toughest restrictions on bank bonuses since the 2008 financial crisis.

Representatives of the Parliament and of the 27 European Union governments were meeting on Tuesday to finalize a deal on banking law that would include pegging bankers’ bonuses at no more than their annual salaries.

The Parliament’s demands for a bonus cap reflect public outrage at continued revelations of huge payouts to bankers. But a side effect has been to hold up enactment of global banking regulations designed to strengthen the capacity of banks to withstand a future crisis.

A majority of member states have come around to supporting the bonus cap. Germany, a late convert to the idea, is prepared to compromise on the issue in order to ensure the wider banking changes are adopted by the elected European Parliament.

The debate has left the British government out on a limb, as it fights a possibly doomed rearguard action to protect the interests of the City of London, Europe’s biggest financial center.

The Conservative-led government believes the bonus cap could have the perverse effect of increasing bankers’ fixed pay, while allowing less opportunity to claw back variable bonuses in the event of poor performance.

Boris Johnson, the outspoken Conservative mayor of London, was quoted on Tuesday as saying, “we don’t need Europe butting in on bonuses,” as he attacked the European proposals as a threat to the City’s international competitiveness.

In the light of popular anti-banker sentiment, however, the British government has been relying on quiet diplomacy to argue its case with European partners in order to avoid the perception that it pushing the agenda of “fat cat” bankers.

It has been left largely to the business media to press the case against a bonus cap. Allister Heath, writing at the City A.M. Web site on Tuesday, suggested that a cap would be a “disaster for London.”

In an editorial this week, which said adoption of the bonus cap would be a defeat for common sense, the Financial Times wrote: “The parliamentarians’ pet idea is a result of populism mixed with ignorance of how banking works.”

“A cap on the ratio of variable to fixed pay will do little to lower total compensation (which is what outrages voters sick of bailing out failed banks),” according to the Financial Times. “It will just encourage higher fixed salaries to compensate for the lack of bonuses that tend to be far larger.”

Mr. Heath, in his City A.M. column, suggested that George Osborne, the British finance minister, was “seemingly too frightened by anti-City sentiment” to block the Brussels proposals.

“The cap will lead to further boosts to base pay, increasing fixed costs and risk,” Mr. Heath wrote. “When business volumes drop, the only answer will be to sack people, rather than cutting bonuses.”

“The fact is U.K. regulators have already created a bonus framework that is tough but fair,” according to Nick Goodway, writing in the London Evening Standard. “Europe is trying to bring in one that could have dire consequences for London’s status as one of the world’s top three financial centers.”

Does this all amount to special pleading on behalf of overpaid bankers? Or do the opponents of the bonus cap have a point? Is the European Parliament guilty of populism, or simply displaying good sense with its proposals to outlaw excessive bonuses?

Michael Jackson's son, Prince Michael, stepped into a world his late father knew well, becoming a special correspondent for Entertainment Tonight.

Mentored by the show's Brooke Anderson, the 16-year-old interviewed actors James Franco, Zach Braff and director Sam Raimi for their new film Oz the Great and Powerful for shows airing this week.

"We have a mutual connection, and I have been working to do something with him for a while," Anderson tells PEOPLE. "I thought interviewing the cast of Oz the Great and Powerful would be the perfect opportunity, because he's a fan of The Wizard of Oz, his dad was in The Wiz and he wants to get into directing, producing and acting one day."

So how were his reporting chops?

"He showed me up big time," Anderson says. "Ultimately, he didn't really need too much guidance. I gave him pointers, but he was a natural."

Hip implants a bit more likely to fail in women

CHICAGO (AP) — Hip replacements are slightly more likely to fail in women than in men, according to one of the largest studies of its kind in U.S. patients. The risk of the implants failing is low, but women were 29 percent more likely than men to need a repeat surgery within the first three years.

The message for women considering hip replacement surgery remains unclear. It's not known which models of hip implants perform best in women, even though women make up the majority of the more than 400,000 Americans who have full or partial hip replacements each year to ease the pain and loss of mobility caused by arthritis or injuries.

"This is the first step in what has to be a much longer-term research strategy to figure out why women have worse experiences," said Diana Zuckerman, president of the nonprofit National Research Center for Women & Families. "Research in this area could save billions of dollars" and prevent patients from experiencing the pain and inconvenience of surgeries to fix hip implants that go wrong.

Researchers looked at more than 35,000 surgeries at 46 hospitals in the Kaiser Permanente health system. The research, published Monday in JAMA Internal Medicine, was funded by the U.S. Food and Drug Administration.

After an average of three years, 2.3 percent of the women and 1.9 percent of the men had undergone revision surgery to fix a problem with the original hip replacement. Problems included instability, infection, broken bones and loosening.

"There is an increased risk of failure in women compared to men," said lead author Maria Inacio, an epidemiologist at Southern California Permanente Medical Group in San Diego. "This is still a very small number of failures."

Women tend to have smaller joints and bones than men, and so they tend to need smaller artificial hips. Devices with smaller femoral heads — the ball-shaped part of the ball-and-socket joint in an artificial hip — are more likely to dislocate and require a surgical repair.

That explained some, but not all, of the difference between women and men in the study. It's not clear what else may have contributed to the gap. Co-author Dr. Monti Khatod, an orthopedic surgeon in Los Angeles, speculated that one factor may be a greater loss of bone density in women.

The failure of metal-on-metal hips was almost twice as high for women than in men. The once-popular models were promoted by manufacturers as being more durable than standard plastic or ceramic joints, but several high-profile recalls have led to a decrease in their use in recent years.

"Don't be fooled by hype about a new hip product," said Zuckerman, who wrote an accompanying commentary in the medical journal. "I would not choose the latest, greatest hip implant if I were a woman patient. ... At least if it's been for sale for a few years, there's more evidence for how well it's working."

Garcetti and Greuel trade shots in mayoral candidates debate

Los Angeles City Councilman Eric Garcetti disparaged rival Wendy Greuel's record as city controller and mocked her campaign platform Monday night in a feisty debate that highlighted the intensifying clash between the top two contenders in the race for mayor.

Greuel defended her record and agenda, but declined to take direct shots at Garcetti. Instead, she accused the entire City Council of failing to act on her findings of waste, fraud and abuse at City Hall.

"They can attack me," she said. "They can attack my numbers. They can attack my auditors. But the one thing they haven't done is attack the problem."

Garcetti's aggressive posture in the Cal State L.A. debate reflects the increasing pressure he faces as Greuel reaps the benefits of more than $1 million in advertising by independent committees funded by public employee unions and other supporters.

It also overshadowed efforts by three other candidates — Councilwoman Jan Perry, entertainment lawyer Kevin James and former tech executive Emanuel Pleitez — to decisively break from the pack during the 90-minute debate, televised live on KABC-TV Channel 7. Voters go to the polls in two weeks.

Garcetti began his assault by challenging as "simply not true" Greuel's frequent statements that she identified $160 million in squandered city money.

"It rests on an accounting maneuver and on unrealistic projections," he said, citing a Times review of audits by Greuel's office.

"What is real," he added, "is real pension reform like we've done the last few years, real cuts and consolidations — the tough choices — not just identifying potential savings, but actually enacting them."

Greuel told viewers that two former controllers, Laura Chick and Rick Tuttle, were supporting her.

"They told me that City Hall would try and kill the messenger, and that's what they're trying to do," she said. "And apparently my opponents don't feel there is any waste. I know there is and I'm going to do something about it."

Garcetti's offensive left James, a former federal prosecutor, in the unfamiliar role of watching another candidate play attack dog.

Nonetheless, he said large raises for city employees — approved by Garcetti, Perry and Greuel when she was on the City Council — show that three longtime officials were "too cozy with the union leaders that have run City Hall."

"We'll talk about cozy later, Mr. James," Perry responded. She too portrayed herself as independent.

"I'm not the favorite of the political power-brokers or insiders because I've never been willing to cut backroom deals or make promises to special interests," said Perry, whose campaign mailers have accused Greuel of selling out to the union representing DWP workers in return for support.

Pleitez struck similar notes, saying he was "tired of the same politicians saying what they're doing, yet the results — there's nothing to show for them."

"Let's take our city in a new direction," said Pleitez.

But it was Garcetti's attacks that stood out.

Alluding to $700,000 spent by the city utility employees' union to benefit Greuel, Garcetti asked, "Do you want a DWP union to buy this election by spending a million dollars on Ms. Greuel's campaign? Or do you want a mayor who is independent enough to make the right decisions and to preserve our democracy?"

Taking aim at her plan to hire more than 2,000 new police officers and 700 new firefighters and paramedics by 2020, Garcetti cited Supervisor Zev Yaroslavsky's criticism of the plan as unrealistic, given the city's budget troubles.

Greuel defended her plan and attacked the council for cutting the Fire Department's budget after the recession hit. She also noted her endorsements by public safety unions.

"The police officers and the firefighters had a choice," she said. "They chose me."

IHT Rendezvous: Human Rights and Sports Events

Earlier this month, President Vladimir V. Putin of Russia sacked a senior Russian Olympic Committee official over rising costs and a delay in the construction work for the 2014 Winter Olympics.

Page Two

Posts written by the IHT’s Page Two columnists.

The cost of the games, to be held in the southern resort of Sochi, is expected to reach the equivalent of $50 billion. Mr. Putin said corruption had pushed up costs.

For human rights organizations, the issue is not cost or corruption. It is the principle of holding such a prestigious event in Russia as the Kremlin implements tough measures against nongovernmental organizations and clamps down on the opposition.

Why, ask human rights organizations, should Russia host such an event when even punk singers, such as some members of the Pussy Riot band, languish in prison? And why should neighboring Belarus be allowed to host the 2014 World Hockey Championships when the regime has imprisoned pro-democracy activists?

Despite the support by some political parties in Europe, human rights organizations have been unable to prevent high-profile events taking place in autocratic countries.

Last April, the Grand Prix was held in Bahrain, the subject of my latest Letter from Europe.

This was despite the fact that the regime had already imprisoned hundreds and killed at least 50 people after the short-lived Arab Spring of February 2011, according to Human Rights Watch. To this day, pro-democracy activists are detained or constantly under surveillance.

It was the same in Azerbaijan, which hosted the Eurovision Song Contest in May 2012. Human rights organizations and some European politicians had called for the event to be held elsewhere because of Azerbaijan’s appalling human rights record. The event went ahead.

A few months later, the European Football Championships were held in Poland and Ukraine. Again, there were calls by pro-democracy activists but also German politicians, to boycott the matches in Ukraine because of the continuing imprisonment of the former prime minister, Yulia Timoshenko. The matches went ahead.

Some politicians argue that it is far better to allow these events to take place in these countries. They put the spotlight on conditions there. But once the event is over, the spotlight moves elsewhere.

Maybe it is time that the international sports federations and the Olympic Committee established democracy criteria for holding such events. They will, no doubt, immediately respond that this is introducing politics into sports. But was there ever a time when sports was innocent?

Kate, Back from Babymoon, Resumes Royal Duties

By Simon Perry

02/18/2013 at 09:20 AM EST

Five months into her pregnancy and just back from a Caribbean "babymoon" in Mustique, the Duchess of Cambridge is stepping up her work as she returns to her royal duties.

Kate, 31, is set for a visit to the port of Grimsby, about 180 miles from London in north eastern England, where she will be shown the local work of one of her father-in-law Prince Charles's best known charities, the Prince's Trust.

On the March 5 "away day," she will also see a local school and take in a history lesson on the local fishing industry when she tours the town's museum.

With the fashion-conscious princess also thinking about her maternity wear, she's reportedly turned to friends Natasha Rufus Isaacs and Lavinia Brennan at Beulah London for some frocks, it was reported Monday – though the company did not wish to comment.

On Tuesday of this week, Kate will return to public work by visiting a treatment center run by one of her charities, Action on Addiction, a women's-only project in Clapham, London.

"These women would have chosen to have some time out of the company of men and they need to focus on themselves," charity chief executive Nick Barton tells PEOPLE. "This is more about the longer term, helping people sustain their recovery and think about the things that makes them vulnerable to relapse."

Royal aides tell PEOPLE that Kate is set to pick some new patronages in the coming weeks, to add to the several she adopted in January 2012.

As it is, the non-profit group 100 Women in Hedge Funds – already associated with Prince William – has announced it will partner with Action on Addiction for Kate's first year of her patronage.

Study: Better TV might improve kids' behavior

SEATTLE (AP) — Teaching parents to switch channels from violent shows to educational TV can improve preschoolers' behavior, even without getting them to watch less, a study found.

The results were modest and faded over time, but may hold promise for finding ways to help young children avoid aggressive, violent behavior, the study authors and other doctors said.

"It's not just about turning off the television. It's about changing the channel. What children watch is as important as how much they watch," said lead author Dr. Dimitri Christakis, a pediatrician and researcher at Seattle Children's Research Institute.

The research was to be published online Monday by the journal Pediatrics.

The study involved 565 Seattle parents, who periodically filled out TV-watching diaries and questionnaires measuring their child's behavior.

Half were coached for six months on getting their 3-to-5-year-old kids to watch shows like "Sesame Street" and "Dora the Explorer" rather than more violent programs like "Power Rangers." The results were compared with kids whose parents who got advice on healthy eating instead.

At six months, children in both groups showed improved behavior, but there was a little bit more improvement in the group that was coached on their TV watching.

By one year, there was no meaningful difference between the two groups overall. Low-income boys appeared to get the most short-term benefit.

"That's important because they are at the greatest risk, both for being perpetrators of aggression in real life, but also being victims of aggression," Christakis said.

The study has some flaws. The parents weren't told the purpose of the study, but the authors concede they probably figured it out and that might have affected the results.

Before the study, the children averaged about 1½ hours of TV, video and computer game watching a day, with violent content making up about a quarter of that time. By the end of the study, that increased by up to 10 minutes. Those in the TV coaching group increased their time with positive shows; the healthy eating group watched more violent TV.

Nancy Jensen, who took part with her now 6-year-old daughter, said the study was a wake-up call.

"I didn't realize how much Elizabeth was watching and how much she was watching on her own," she said.

Jensen said her daughter's behavior improved after making changes, and she continues to control what Elizabeth and her 2-year-old brother, Joe, watch. She also decided to replace most of Elizabeth's TV time with games, art and outdoor fun.

During a recent visit to their Seattle home, the children seemed more interested in playing with blocks and running around outside than watching TV.

Another researcher who was not involved in this study but also focuses his work on kids and television commended Christakis for taking a look at the influence of positive TV programs, instead of focusing on the impact of violent TV.

"I think it's fabulous that people are looking on the positive side. Because no one's going to stop watching TV, we have to have viable alternatives for kids," said Dr. Michael Rich, director of the Center on Media and Child Health at Children's Hospital Boston.

Major donor to GOP helping L.A. mayoral candidate Kevin James

Dallas billionaire Harold Simmons and Los Angeles mayoral candidate Kevin James crossed paths just once.

It was an intimate cocktail fundraiser for James in the tony Montecito enclave near Santa Barbara, where Simmons owns a weekend retreat and counts Oprah Winfrey among his neighbors. Simmons, one of the top donors to Republican "super PACs" in 2012, turned to the candidate and asked, "What on Earth can you do to save L.A.?"

James, recounting the exchange, said he launched into his political pitch, railing against the city's flirtation with bankruptcy and the power of its labor unions. "I remember him telling me he was impressed," James said.

Later, when James made formal remarks to the group, which included a few of Simmons' fellow Texans, the industrial magnate stood up and announced that he would give. By mid-January, Simmons had given $600,000 to an independent group backing James, making him the largest single contributor to any political committee affiliated with the L.A. mayor's race — a sphere most often dominated by labor unions.

His contributions made it possible for a super PAC known as Better Way LA, created by GOP ad man Fred Davis, to buy half a million dollars of TV ad time last week promoting James, the only Republican in the race.

But that political help could come at a price in a city as liberal and Democratic as Los Angeles, where James needs to win over moderates, as well as conservatives, to reach a two-way runoff in May. In recent years, Simmons has funded some of the most controversial conservative groups in presidential politics, and last year he called President Obama "the most dangerous American alive."

Simmons' interest in city politics and a long shot like James remains something of a mystery. A corporate investor whose net worth was valued at $7.1 billion by Forbes last September, Simmons declined to be interviewed. He votes in Texas and has not contributed to any other Los Angeles city candidates in recent years, according to election records.

By the standards of his past political giving, Simmons' support for the pro-James super PAC has been small.

In last year's presidential race, Simmons, his wife, his companies and their employees gave $31 million to a network of super PACs that proliferated after the Supreme Court's 2010 Citizens United ruling, which loosened the reins on political spending by corporations and labor unions, according to the Center for Responsive Politics.

"This is one of a handful of mega-donors in U.S. politics who has given extraordinary sums of money over many, many years," said Sheila Krumholz, the center's executive director who has monitored Simmons' political giving for two decades. "He's a savvy donor, somebody who is very familiar with how this game is played at the highest levels and on down."

James, an openly gay Republican, said he knew of no specific business that Simmons has before the city. And Simmons did not mention any particular Los Angeles issue, he said.

James suggested that Simmons, 81, may be interested in elevating a moderate Republican voice statewide. Simmons has contributed to another California moderate, former Gov. Arnold Schwarzenegger, and told the Wall Street Journal last year that he was "probably pro-choice."

"For donors who are looking for the Republican Party to be able to plant a flag again in California," James said, "I'm the kind of Republican that's a bigger-tent Republican."

In that rare interview he granted the Wall Street Journal last year, Simmons said he wanted to make the U.S. tax and regulatory structure more friendly to business by electing Republicans at all levels of government. He said he hoped like-minded individuals would make political donations to help counter spending by labor unions.

In 2004, Simmons donated $3 million to Swift Boat Veterans for Truth, a group that ran ads accusing then-Democratic presidential candidate John Kerry of exaggerating his record in the Vietnam War. And during President Obama's first run, Simmons was the sole funder of the American Issues Project, which ran TV ads tying Obama to a founder of the Weather Underground, which planned a series of bombings to protest the Vietnam War.

In his interview with the Journal, Simmons described Obama as "a socialist" who "would eliminate free enterprise in this country."

At times, Simmons' political contributions have tracked closely with his business interests — a network of companies that include hazardous waste disposal and metal component manufacturers.

He was a generous backer of Texas Gov. Rick Perry at a time when one of those companies, Waste Control Specialists, needed the governor's backing to build a low-level radioactive waste disposal site, the nation's first such new facility in three decades.

After a fierce lobbying campaign, Perry signed a law opening the way for the proposal. Perry appointees later approved the license for the $500-million site in West Texas despite concerns of some state environmental experts about potential harm to aquifers near the site. Simmons' spokesman has said that Simmons' connections to Perry did not work to his company's advantage and in fact increased the state's scrutiny of the deal.

Krumholz said Simmons' companies span so many fields that it has been difficult to trace possible ties between his business interests and his giving even at the federal level.

"He's kind of like the AT&T of individual donors," said Krumholz, noting that the telecommunications giant has interests in defense contracting and other industries. "He might have reason to be involved at various levels of government and in specific races because his investments are so diverse."
