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."

Wall Street little changed after data, Fed minutes on tap

NEW YORK (Reuters) - Stocks were little changed on Wednesday after housing and inflation data pointed to a continuation of modest economic improvement and ahead of the minutes from the Federal Open Market Committee's January meeting later in the session.

Groundbreaking to build new U.S. homes fell 8.5 percent in January but new permits for construction rose to a 4 1/2-year high while producer prices rose in January for the first time in four months.

The data should enable the Fed to maintain its easy monetary policy in its efforts to stimulate the economy.

Later in the session, investors will look to the minutes from the Fed's January meeting for any indication as to how long the current monetary policy will remain in effect.

"It's hard in any given data point to take a strong conclusion that we are moving dramatically forward, but over time, clearly things are getting better," said Robert Lutts, chief investment officer at Cabot Money Management in Salem, Massachusetts.

Lutts described an economy that was addicted to stimulus.

"The bottom line is the economy is on heroin today and we will at one time move to a diluted form of heroin, but it's very important for people to remember we are still on an unbelievably aggressive, never-seen-before accommodative policy and this economy is going to improve."

The S&P 500 <.spx> is up more than 7 percent for the year, fueled by legislators' ability to sidestep an automatic implementation of spending cuts on tax hikes on January 1, better-than-expected corporate earnings and modestly improving economic data that has been tepid enough for the Fed to maintain its stimulus policy.

The Dow Jones industrial average <.dji> dropped 5.99 points, or 0.04 percent, to 14,029.68. The Standard & Poor's 500 Index <.spx> lost 2.60 points, or 0.17 percent, to 1,528.34. The Nasdaq Composite Index <.ixic> shed 3.12 points, or 0.10 percent, to 3,210.48.

U.S. oil and gas producer Devon Energy Corp reported a fourth-quarter loss as it wrote down the value of its assets by $896 million due to weak gas prices. Shares dipped 1.6 percent to $59.60.

OfficeMax Inc and Office Depot Inc shares were halted as the companies announced a merger agreement. An earlier online statement of the deal was pulled down as an agreement had not yet been struck.

Toll Brothers Inc lost 4 percent to $35.43 after the largest luxury homebuilder in the United States, reported first-quarter results well below analysts' estimates.

SodaStream dropped 3.2 percent to $50.79 after the seller of home carbonated drink maker machines posted fourth-quarter earnings and provided a 2013 outlook.

According to Thomson Reuters data through Tuesday morning, of the 391 companies in the S&P 500 that have reported results, 70.1 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.6 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Bulgarian government resigns amid growing protests

SOFIA (Reuters) - Bulgaria's government resigned on Wednesday after mass protests against high power prices and falling living standards, joining a long list of European administrations felled by austerity during four years of debt crisis.

Prime Minister Boiko Borisov, an ex-bodyguard who took power in 2009 on pledges to root out graft and raise incomes in the European Union's poorest member, faces a tough task of propping up eroding support ahead of an expected early election.

Wage and pension freezes and tax hikes have bitten deep in a country where earnings are less than half the EU average and tens of thousands of Bulgarians have rallied in protests that have turned violent, chanting "Mafia" and "Resign".

Moves by Borisov on Tuesday to blame foreign utility companies for the rise in the cost of heating homes was to no avail and an eleventh day of marches saw 15 people hospitalized and 25 arrested in clashes with police.

"My decision to resign will not be changed under any circumstances. I do not build roads so that blood is shed on them," said Borisov, who began his career guarding the Black Sea state's communist dictator Todor Zhivkov.

A karate black belt, Borisov has cultivated a Putin-like "can-do" image since he entered politics as Sofia mayor in 2005 and would connect with voters by showing up on the capital's rutted streets to oversee the repair of pot-holes.

But critics say he has often skirted due process, sometimes to the benefit of those close to him, and his swift policy U-turns have wounded the public's trust.

The spark for the protests was high electricity bills, after the government raised prices by 13 percent last July. But it quickly spilled over into wider frustration with Borisov and political elites with perceived links to shadowy businesses.

"He made my day," said student Borislav Hadzhiev in central Sofia, commenting on Borisov's resignation. "The truth is that we're living in an extremely poor country."

POLLS, PRICES

The prime minister's final desperate moves on Tuesday included cutting power prices and risking a diplomatic row with the Czech Republic by punishing companies including CEZ, moves which conflicted with EU norms on protection of investors and due process.

CEZ officials were hopeful on Wednesday that it would be able to avoid losing its distribution license after all and officials from the Bulgarian regulator said the company would not be punished if it dealt with breaches of procedure.

But shares in what is central Europe's largest publicly-listed company fell another 1 percent on Wednesday.

If pushed through, the fines for CEZ and two other foreign-owned firms will not encourage other investors in Bulgaria, who already have to navigate complicated bureaucracy and widespread corruption and organized crime to take advantage of Bulgaria's 10-percent flat tax rate.

Financial markets reacted negatively to the turbulence on Wednesday. The cost of insuring Bulgaria's debt rose to a three-month high and debt yields rose some 15 basis points, though the country's low deficit of 0.5 percent of gross domestic product means there is little risk to the lev currency's peg against the euro.

Borisov's interior minister indicated that elections originally planned for July would probably be pulled forward by saying that his rightist GERB party would not take part in talks to form a new government.

MILLIONS GONE

GERB's woes have echoes in another ex-communist EU member, Slovenia, where demonstrators have taken to the streets and added pressure to a crumbling conservative government.

A small crowd gathered in support of Borisov outside Sofia's parliament, which is expected to approve his resignation on Thursday, while bigger demonstrations against the premier were expected in the evening.

Unemployment in the country of 7.3 million is far from the highs hit in the decade after the end of communism but remains at 11.9 percent. Average salaries are stuck at around 800 levs ($550) a month and millions have emigrated, leaving swathes of the country depopulated and little hope for those who remain.

GERB's popularity has held up well and it still led in the latest polls before protests grew in size last weekend, but analysts say the opposition Socialists should draw strength from the demonstrations.

The leftists, successors to Bulgaria's communist party, have proposed tax cuts and wage hikes and are likely to raise questions about public finances if elected.

Michelle Obama: My Bangs Were a 'Midlife Crisis'

Taylor Hill/WireImage

When you’re the First Lady of the United States, you don’t have many options if you’re looking to act on a midlife crisis.

So Michelle Obama did what any woman looking to shake things up (within Secret Servce-approved parameters, of course) would do: cut her bangs.

“This is my midlife crisis, the bangs,” Obama joked on The Rachael Ray Show. “I couldn’t get a sports car. They won’t let me bungee-jump. So instead, I cut my bangs.”

And unlike many midlife crises, this one has gotten a big thumbs up from her spouse. “I love her bangs!” President Barack Obama said shortly after she cut them on her 49th birthday. “She always looks good.”

Not that she needed her husband’s approval, of course; though President Obama may be the leader of the free world, his wife is strictly the boss of her own hair. “I can do this,” she told Ray, smiling and gesturing to her new cut. “This is all mine.”

Tell us: Have you ever changed up your look impulsively? What do you think of Obama’s “midlife crisis”?

UK patient dies from SARS-like coronavirus

LONDON (AP) — A patient being treated for a mysterious SARS-like virus has died, a British hospital said Tuesday.

Queen Elizabeth Hospital in Birmingham, central England, said the coronavirus victim was also being treated for "a long-term, complex unrelated health problem" and already had a compromised immune system.

A total of 12 people worldwide have been diagnosed with the disease, six of whom have died.

The virus was first identified last year in the Middle East. Most of those infected had traveled to Qatar, Saudi Arabia, Jordan or Pakistan, but the person who just died is believed to have caught it from a relative in Britain, where there have been four confirmed cases.

The new coronavirus is part of a family of viruses that cause ailments including the common cold and SARS. In 2003, a global outbreak of SARS killed about 800 people worldwide.

Health experts still aren't sure exactly how humans are being infected. The new coronavirus is most closely related to a bat virus and scientists are considering whether bats or other animals like goats or camels are a possible source of infection.

Britain's Health Protection Agency has said while it appears the virus can spread from person to person, "the risk of infection in contacts in most circumstances is still considered to be low."

Officials at the World Health Organization said the new virus has probably already spread between humans in some instances. In Saudi Arabia last year, four members of the same family fell ill and two died. And in a cluster of about a dozen people in Jordan, the virus may have spread at a hospital's intensive care unit.

Wall Street gains on M&A optimism, health insurers weigh

NEW YORK (Reuters) - U.S. stocks advanced on Tuesday after the long holiday weekend and a seven-week winning streak for the S&P 500 as merger activity buoyed investor optimism, but health insurer shares muted gains.

Office Depot Inc surged 21.6 percent to $5.58 after a person familiar with the matter said the No. 2 U.S. office supply retailer is in advanced talks to merge with smaller rival OfficeMax Inc . A deal could come as early as this week.

OfficeMax shares jumped 28.8 percent to $13.85 while larger rival Staples Inc shot up 15.1 percent to $14.91 as the best performer on the S&P 500.

"M&A is providing an enormous amount of enthusiasm in pockets and it is really a function of the cost of money, the cost of borrowing. It is a sign there is a shift going on in the economy that is very, very positive," said Peter Kenny, managing director at Knight Capital in Jersey City, New Jersey.

"At the same time, if you take the M&A activity out of the picture, you will see that many on the Street are expecting a pullback.

The Dow Jones industrial average <.dji> rose 59.94 points or 0.43 percent, to 14,041.7, the S&P 500 <.spx> gained 6.62 points or 0.44 percent, to 1,526.41 and the Nasdaq Composite <.ixic> added 12.01 points or 0.38 percent, to 3,204.04.

U.S. markets were closed on Monday for the Presidents Day holiday.

Health insurer stocks tumbled, led lower by a 9 percent drop in Humana Inc to $70.98 after the company said the government's proposed 2014 payment rates for Medicare Advantage participants were lower than expected and would hurt its profit outlook.

UnitedHealth Group lost 2.9 percent to $55.68 as the biggest drag on the Dow. The Morgan Stanley healthcare payor index <.hmo> dropped 2.8 percent.

The benchmark S&P index is up 7 percent for the year and is coming off its longest weekly winning streak since January 2011.

The strong start was fueled by legislators in Washington temporarily averting automatic spending cuts and tax hikes as well as by stronger-than-expected earnings and economic data. The Federal Reserve's stimulus policy has also been a major factor.

But further gains for the S&P 500 have been a struggle as investors look for new catalysts to lift the index, which hovers near five-year highs.

The compromise by lawmakers on across-the-board spending cuts, known as sequestration, only postponed the matter, and Democrats and Republicans have until March 1 to resolve differences or the cuts, which are predicted to damage the economy, will take effect.

The uptick in merger and acquisition activity, a sign of optimism about the outlook on Wall Street, has resulted in more than $158 billion in deals announced so far in 2013.

Last week, deals were reached for the acquisition of H.J. Heinz Co by Berkshire Hathaway and the sale by General Electric of its remaining stake in NBCUniversal to Comcast Corp .

Economic data showed the NAHB/Wells Fargo Housing Market index edged down to 46 in February from 47 in the prior month and below expectations of 48 as builders faced higher material costs.

Express Scripts rose 2.6 percent to $57 after the pharmacy benefits manager posted fourth-quarter earnings.

According to the Thomson Reuters data through Monday morning, of the 391 companies in the S&P 500 that have reported results, 70.1 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.6 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Venezuela's Maduro would win vote if Chavez goes: poll

CARACAS (Reuters) - Venezuelan Vice President Nicolas Maduro would win a presidential vote should his boss Hugo Chavez's cancer force him out, according to the first survey this year on such a scenario in the South American OPEC nation.

Local pollster Hinterlaces gave Maduro 50 percent of potential votes, compared to 36 percent for opposition leader Henrique Capriles.

Chavez made a surprise return to Venezuela on Monday, more than two months after cancer surgery in Cuba, to continue treatment at home for the disease that is jeopardizing his 14-year socialist rule.

He has named Maduro, 50, a former bus driver and union activist, as his preferred successor.

Capriles, 40, a center-left state governor who lost to Chavez in a presidential vote last year, likely would run again.

Chavez still has not spoken in public since his December 11 operation in Cuba. Venezuelans were debating on Tuesday the various possible scenarios after his homecoming - from full recovery to resignation or even death from the cancer.

There was widespread expectation Chavez would soon be formally sworn in for his new six-year term at the Caracas military hospital where officials said he was staying. The January 10 ceremony was postponed while he was in Cuba.

"The president's timeline is strictly linked to his medical evolution and recovery," said Rodrigo Cabezas, a senior member of Chavez's ruling Socialist Party who, like other officials, would not comment on when he might be sworn in.

CAPRILES ANGRY

Should Chavez be forced out, Venezuela's constitution stipulates an election must be held within 30 days, giving Capriles and the opposition Democratic Unity coalition another chance to end the socialists' lengthy grip on power.

Capriles, who crossed swords with Hinterlaces at various points during the presidential election, again accused its director, Oscar Schemel, of bias in the latest survey.

"That man is not a pollster, he's on the government's payroll," Capriles told local TV.

"He said in December I would lose the Miranda governorship," he added, referring to his defeat of government heavyweight Elias Jaua, now foreign minister, in that local race.

Opinion surveys are notoriously controversial and divergent in Venezuela, with both sides routinely accusing pollsters of being in the pocket of the other. But Hinterlaces successfully forecast Chavez's win with 55 percent of the vote in October.

Its latest poll was of 1,230 people between January 30-February 9.

Polls last year showed Capriles - an energetic basketball-playing lawyer who admires Brazil's centrist mix of free-market economics with strong social welfare policies - as more popular than any of Chavez's senior allies.

But Chavez's personal blessing of Maduro, on the eve of his last cancer surgery, has transformed his status and made him the heir apparent for many of the president's supporters.

As de facto leader since mid-December, Maduro also has built up a stronger public profile, copying the president's techniques of endless live TV appearances, especially to inaugurate new public works or promote popular policies like subsidized food.

He lacks Chavez's charisma, however, and opponents have slammed him as a "poor imitation" and incompetent.

EMOTION

Local analyst Luis Vicente Leon said that should Chavez die, Maduro would benefit from the emotion unleashed among his millions of passionate supporters in Venezuela.

"The funeral wake for Chavez would merge into the election campaign," he told a local newspaper, noting how Argentine President Cristina Fernandez's popularity surged when her husband and predecessor Nestor Kirchner died in 2010.

Maduro already has implemented an unpopular devaluation of the local currency and said more economic measures are coming this week in what local economists view as austerity measures after blowout spending prior to last year's election.

In Caracas, the streets were quieter after tumultuous celebrations of Chavez's homecoming by supporters on Monday. A few journalists stood outside the military hospital.

Prayer vigils were planned in various parts of Venezuela.

"We hope Chavez will stay governing because he is a strong man," supporter Cristina Salcedo, 50, said in Caracas.

Student demonstrators who had chained themselves near the Cuban Embassy last week, demanding more information on Chavez's condition, called off their protest after his return.

Until photos were published of him on Friday, the president had not been seen by the public since his six-hour December 11 operation, the fourth since cancer was detected in mid-2011.

The government has said Chavez is breathing through a tracheal tube and struggling to speak.

Bolivian President Evo Morales arrived in Caracas on Tuesday in the hope of visiting his friend and fellow leftist.

Reeva Steenkamp's Mom Wants Answers: 'Why My Little Girl?'

By Andrea Billups and Peter Cox

02/18/2013 at 10:30 AM EST

Reeva Steenkamp and Oscar Pistorius

Gallo Images/REX USA

As "Blade Runner" Oscar Pistorius prepares to return to court on Tuesday, where he will likely seek bail, the grieving mother of his dead girlfriend, model Reeva Steenkamp, has called for answers in the case, asking, "Why my little girl?"

June Steenkamp, in an interview with the Times newspaper of South Africa, wonders "Why did he do this? … She loved like no one else could love. Just like that, she is gone."

Pistorius's agent, Pete van Zyl, visited him in jail over the weekend and told PEOPLE it was too early to determine what the charges might mean for the star's running career. He would not comment on the case and said he was there to lend support to Pistorius and update him on sponsorship, contracts and future races.

"I can tell you that we have had overwhelming support from Oscar from a lot of fans on a global scale, really on a global scale. South African fans, international fans from literally all over the world," van Zyl told PEOPLE. "He knows it. I have given him that message."

Meanwhile, new details continue to emerge surrounding Steenkamp's death. Citing a police official close to the case, CNN reports that Steenkamp, 30, was shot through the bathroom door inside Pistorius's house.

She reportedly also was alive after the shooting, with Pistorius carrying her downstairs in a frantic effort to save her life. Local media in his hometown of Pretoria have reported that Pistorius, 26, thought Steenkamp was an intruder and shot her by accident.

Monday's Today show reported that Pistorius called friends around 4 a.m. the day of the shooting to ask for help, telling them there had been a terrible accident and that Steenkamp had been shot. (Neighbors who had reportedly heard commotion at the Olympian's home, called police.)

Reuters, citing an eyewitness account published in the Sunday Argus of a paramedic on the scene, said Steenkamp was already dead when he arrived.

The reports said she had been shot once in the head and in the arm, where the bullet broke the bone, and was lying at the bottom of the stairs wearing a black sweatshirt and long pants, but without shoes. When told she could not be revived, Pistorius began to cry, the medic said.

Through his agent, Pistorius has rejected any suggestion that Steenkamp was murdered. The couple had been dating since November. Her publicist told Today that the couple had "seemed happy."

Prosecutors said on Friday that they planned to pursue a charge of premeditated murder. If convicted on that charge, Pistorius would face life in prison.

Pistorius' father, Henke Pistorius, told the Sunday Telegraph that his family thinks the shooting was an accident based on their son's thinking Steenkamp was an intruder inside his home.

"When you are a sportsman, you act even more on instinct," said Henke Pistorius. "It's instinct – things happen and that's what you do."

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.
