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 dips on weakness in energy

DEAR ABBY: My boyfriend, "Doug" (24), and I (22) have been in a long-distance relationship for a year, but we were friends for a couple of years before that. I had never had a serious relationship before and lacked experience. Doug has not only been in two other long-term relationships, but has had sex with more than 15 women. One of them is an amateur porn actress.I knew about this, but it didn't bother me until recently. Doug had a party, and while he was drunk he told one of his buddies -- in front of me -- that he should watch a certain porn film starring his ex-girlfriend. ...

French Family of 7 Kidnapped in Cameroon

PARIS (AP) — A French family of seven — including four children — was kidnapped on Tuesday in northern Cameroon, and officials suggested that the Islamic extremist sect Boko Haram was behind it.

Details of the kidnapping were not immediately clear. However, President Francois Hollande, speaking during a visit to Greece, noted that France is engaged in a military campaign in Mali to rout out jihadists who had taken control of the north. Terrorists, he said, "are not just in Mali."

Hollande warned French citizens in the region to avoid putting themselves in dangerous situations.

A total of 15 French citizens are currently being held in western Africa — one other in Nigeria and seven thought to be in northern Mali.

A French official close to the embassy in Cameroon said the family was believed to have been taken from northern Cameroon to Nigeria, where on Monday a little-known extremist group called Ansaru claimed responsibility for a separate abduction of seven foreigners.

Boko Haram — which means "Western education is sacrilege" — has launched a guerrilla campaign of bombings and shootings across Nigeria's predominantly Muslim north. It is blamed for at least 792 killings last year alone, according to an AP count. It is known to have ties to al-Qaida in the Islamic Maghreb, or AQIM, an Algerian-based group that opened a front in Mali.

"If everything is confirmed, this signifies that the fight against terrorist groups is a necessity," Foreign Minister Laurent Fabius said in Paris. "There is a battle to be led by the international community against terrorist groups and narco-terrorists," a reference to the trafficking in drugs, cigarettes and other commodities that has flourished in northern Mali under the extremists.

The latest kidnappings have added to fears of instability and danger toward Westerners. Before Tuesday, there were eight French citizens being held in the region, including one who was taken in Nigeria.

An analysis published Monday by Stratfor, a U.S.-based private global intelligence firm, warned that there likely will be more attacks by Ansaru targeting Westerners and Western interests in Nigeria, as well as neighboring nations.

Mindy McCready Made Heartbreaking Video for Suicide Prevention

By Patrick Gomez and Champ Clark

02/19/2013 at 11:40 AM EST

Just days before her apparent suicide, Mindy McCready was ready to release a suicide-prevention video dedicated to her deceased boyfriend David Wilson.

As she sings "I'll See You Yesterday," a song intended for her next album, a photo of a rural scene transitions to pictures of McCready and Wilson, followed by contact information for suicideispreventable.org. It had been intended to be used as a PSA.

"She told me that it was beautiful, it made her cry and was exactly what she wanted," says Dan "Danno" Hanks, a private investigator friend who produced the video. "I asked her if I could post it and Mindy's answer was, 'You'll know when it's right.' In hindsight she was having me produce her suicide video."

Hanks posted the video on YouTube on Sunday after McCready was found dead on the porch of her Arkansas home after apparently shooting herself. Last month, Wilson was found dead in the same house, also with a gunshot wound to the head.

The song, written by McCready pal Courtney Dashe and co-writer Jason Walker, is about remembering the good in relationships that had gone sour.

"We know she has been through a lot and the song clearly resonated with her," says Dashe, who watched McCready cry after hearing the song for the first time in 2009. "[Danno] said the song had been really helping her cope with the loss of her boyfriend."

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.

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?

Danica Patrick Makes History as First Woman to Win Daytona 500 Pole Slot

By Andrea Billups

02/18/2013 at 11:30 AM EST

Danica Patrick made racing history on Sunday, becoming the first woman to win the coveted pole position for this year's Daytona 500 in just her second season of racing NASCAR after years as an IndyCar driver.

"I was brought up to be the fastest driver, not the fastest girl," Patrick, 30, told CBS News. "That was instilled in my from very young, from the beginning.

"I've been lucky in my career to be with good teams and have good people around me," Patrick said. "I don't think any of it would have been possible without that."

Patrick started in eighth position in qualifying rounds on Sunday, clocking her fastest lap at 196.434 mph in her No. 10 Chevrolet SS stock car at the Daytona International Speedway in Florida. Two hours and 37 other competitive drivers later, her time put her on top, letting her start the famed race, set for Feb. 24, in the most-coveted position.

Patrick posted photos of her Pole Award on her Facebook page. She crashed last year in her first Daytona 500 try.

Previously, the photogenic Patrick, who has modeled and directed TV ads, became the first woman to win an IndyCar race, when she led the pack in 2008 in Japan.

Her personal life faced scrutiny last year when she announced her split from husband Paul Hospenthal, 47, a physical therapist and personal training expert for golfers. The couple had been married for seven years.

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.

Yen resumes fall after G20, U.S. holiday thins trade

LONDON (Reuters) - The yen resumed falling on Monday after Japan signaled it would push ahead with expansionist monetary policies having escaped criticism from the world's 20 biggest economies at the weekend.

Industrial metals also dipped and European shares were soft on lingering worries about the economic outlook, especially for the euro zone. While the risk of an inconclusive outcome in Italy's forthcoming election added to investor concerns.

However, activity was curtailed by the closure of markets in the United States for the Presidents' Day holiday.

The yen, which has dropped 20 percent against the dollar since mid-November, fell further after financial leaders from the G20 promised not to devalue their currencies to boost exports and avoided singling out Japan for any direct criticism.

The dollar rose 0.5 percent to 93.95 yen, near a 33-month peak of 94.47 yen set a week ago. The euro added 0.3 percent to 125.40 yen, to be midway between Friday's two-week low of 122.90 and a 34-month high of 127.71 yen hit earlier this month.

Strategists said the yen was likely to stay weak, though its decline could lose momentum until it becomes clear who will be taking the helm at the Bank of Japan when the current governor steps down on March 19.

"The yen probably will weaken a little further in anticipation of more aggressive easing under a new leadership team at the Bank of Japan," said Julian Jessop, chief global economist at Capital Economics.

Japan's Prime Minister Shinzo Abe is poised to nominate the new governor in the next few days. Sources have told Reuters that former financial bureaucrat Toshiro Muto, considered likely to be less radical than other candidates, was leading the field.

Meanwhile the euro dipped slightly against the dollar when European Central Bank president Mario Draghi said the currency's recent gains made any rise in inflation less likely and added that he had yet to see any improvement in the euro zone economy.

Speaking before the European Parliament, Draghi said the euro's exchange rate was not a policy target but was important for growth and stability, adding that appreciation of the euro "is a risk".

The comments left the euro down 0.2 percent at $1.3334.

Elsewhere in the currency market, sterling hit a seven-month low against the dollar, after a key policymaker made comments about the need for further weakness and recent poor data which has kept alive worries of another British recession.

Sterling fell 0.25 percent to $1.5476 having earlier touched $1.5438, its lowest since July 13.

DATA LOOMS

A big week for data on the outlook for the world's economy weighed on other riskier asset markets following the recent dire fourth-quarter growth numbers for the euro zone and Japan, along with Friday's soft U.S. manufacturing figures.

In European markets, attention is focused on the euro area Purchasing Managers' Indexes for February and German sentiment indices due later in the week which could affect hopes for a recovery this year.

Analysts expect Thursday's euro area flash PMI indices, which offer pointers to economic activity around six months out, to show growth stabilizing across the recession-hit region, leaving intact hopes for a recovery in the second half of 2013.

Concerns over an inconclusive outcome in the Italian election on Sunday and Monday have added to the weaker sentiment as a fragmented parliament could hamper a future government's efforts to reform the struggling economy.

The worries about the outlook for Italy were encouraging investors back into safe-haven German government bonds on Monday, with 10-year Bund yields easing 3.5 basis points to be around 1.63 percent.

"Political uncertainty will keep Bunds well bid this week," ING rate strategist Alessandro Giansanti said, adding that only better than expected economic data could create selling pressure on German debt in the near term.

Italian 10-year yields were 4 basis points higher on the day at 4.41 percent.

EARNINGS HIT

European equity markets were taking their lead from corporate earnings reports which have been reflecting the sluggish economic conditions across the region.

Danish brewer Carlsberg , which generates just over 60 percent of its sales in western Europe, became the latest to report a weaker-than-expected quarterly profit, sending its shares to their lowest level in almost a month.

The 5.8-percent drop for shares in the world's fourth biggest brewery helped send the FTSEurofirst 300 index <.fteu3> of top European shares down 0.2 percent. Germany's DAX <.gdaxi>, France's CAC-40 <.fchi> and Britain's FTSE-100 <.ftse> ranged between 0.4 percent up and 0.15 percent lower.

Earlier, the G20 statement and subsequent comment from Prime Minster Abe indicating a renewed drive to stimulate the Japanese economy lifted the Nikkei stock index <.n225> by 2.1 percent, near to its highest level since September 2008.

MSCI's world equity index <.miwd00000pus> was flat as markets extended a two-week period of consolidation that has followed the big run-up in January, when demand was buoyed by the efforts of central banks to stimulate the world economy.

Data from EPFR Global, a U.S.-based firm that tracks the flows and allocations of funds globally, shows investors pulled $3.62 billion from U.S. stock funds in the latest week, the most in 10 weeks after taking a neutral stance the prior week.

But demand for emerging market equities remained strong, with investors putting $1.81 billion in new cash into stock funds, the fund-tracking firm said.

CHINA RETURN

In the commodity markets, traders played catch-up after a week-long holiday last week in China, the world's second biggest consumer of many raw materials, which had kept activity subdued, with worries about the economic outlook weighing on sentiment.

Copper, for which China is the world's largest consumer, dipped to a near three-week low at $8,125.25 a metric ton (1.1023 tons) on the London futures market. Benchmark tin and nickel also touched three-week lows.

Gold managed to edge away from six-month lows as jewelers in China returned to the physical market after the Lunar New Year holiday but a lack of demand from U.S. markets saw the precious metal slip back to be down 0.1 percent to $1,607.06 an ounce.

Crude oil markets were mostly steady after the weak U.S. industrial production data on Friday [ID:nL1N0BF44A] was seen dampening demand, while tensions in the Middle East lent some support.

"We continue to see a mixed picture out of the United States. Industry output was lower than expected but that shouldn't affect the general upward direction," Olivier Jakob, analyst at Geneva-based Petromatrix, said.

Brent crude was down 20 cents at $117.46 a barrel after posting its first weekly loss since the first half of January. U.S. crude slipped 24 cents to $95.62.

IHT Rendezvous: Should Common Plastics Be Labeled Toxic?

THE HAGUE — Hoping to reduce one of the most ubiquitous forms of waste, a global group of scientists is proposing that certain types of plastic be labeled hazardous.

The group, led by two California scientists, wrote in this week’s issue of the scientific journal Nature:

We believe that if countries classified the most harmful plastics as hazardous, their environmental agencies would have the power to restore affected habitats and prevent more dangerous debris from accumulating.

While 280 million tons of plastic were produced globally last year, less than half of that plastic has ended up in landfills or was recycled, according to the scientists’ data. Some of the unaccounted for 150 million tons of plastic is still in use, but much of it litters roadsides, cities, forests, deserts, beaches and oceans. (Just think of the great floating garbage patches at sea).

Unlike other forms of solid waste, such as uneaten food, scrap metal or last year’s clothes, plastics take an especially long time to break down. And when they finally do, they create hazardous, even toxic particles that can harm wildlife, ecosystems and humans.

For now, the group — led by Chelsea M. Rochman of the School of Veterinary Medicine at the University of California, Davis, and Mark Anthony Browne at the National Center for Ecological Analysis and Synthesis in Santa Barbara, California — is calling for the reclassification of plastics that are particularly difficult to recycle and that are most toxic when degrading: PVC, polystyrene, polyurethane and polycarbonate.

The scientists say these types of plastics — used in construction, food containers, electronics and furniture — make up an estimated 30 percent of all plastics produced.

Join our sustainability conversation. Does it make sense to re-classify common plastics as hazardous, or are there better ways to reduce the amount of plastics we throw out?
