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."

Pistorius Shots Said to Come From High Angle

At the second day of a bail hearing for Olympian Oscar Pistorius, a South African investigator who arrived at the scene of the Feb. 14 fatal shooting said that Reeva Steenkamp was shot from a high angle, which prosecutors say contradicts the runner's account that he was not wearing his prosthetics when he shot his girlfriend to death.

Pistorius, a double-amputee who runs on carbon-fiber blades, appeared in court for the second day in a row after his arrest in the death of girlfriend Steenkamp at his gated home in Pretoria, South Africa.

Arresting officer Hilton Botha told the court today that the 26-year-old was standing in the master bathroom when he shot the supermodel, who was crouched in a defensive position behind a locked door in a smaller powder room. He also said that the bullets that were fired had been fired from high up, and the bullets seemed to be coming in a downward direction.

"[The angle] seems to me down. Fired down," Botha told the court.

Pistorius said Tuesday that he went to the bathroom and fired through the door before putting on his prosthetic legs.

He said he mistakenly shot his girlfriend, thinking she was an intruder.

Prosecutors also said that they found two boxes of testosterone in the bedroom, although the defense disputes that, saying it's just herbal supplements.

The court also heard that a witness, someone about 2,000 feet away from Pistorius' home, heard nonstop fighting the morning of the shooting.

"We have a witness who says she heard non-stop shouting and fighting between 2 and 3 a.m.," said prosecutor Gerrie Nel, who added that another witness saw lights on at the time of the gunshots.

Pistorius says he spent a quiet night with Steenkamp before the shooting.

Nel said that Pistorius' actions and phone calls on the night indicate pre-planning, and that there was a "deliberate aiming of shots at the toilet from about 1.5 meters [about 5 feet]."

He says Steenkamp was shot on the right side of her body.

Officer Botha also said Pistorius should be considered a flight risk because investigators discovered that he has offshore bank accounts and a house in Italy.

"I think it would be hard to get him back," Botha told the court. "This is a very serious crime, shooting an unarmed woman behind closed door."

Prosecutors also say they may file more charges for unlicensed ammunition, after a special-caliber .38 round was found in a safe in Pistorius' home.

Botha told the court today that he arrived at Pistorius' home at 4:15 a.m. Valentine's Day to find Steenkamp already dead, dressed in a white shorts and a black vest, and covered in towels. The only thing that Pistorius said was, 'I thought it was a burglar,'" according to Botha.

The 26-year-old sprinter Tuesday denied that he willfully killed Steenkamp, telling the court that he shot the woman through his bathroom door because he believed she was an intruder.

Botha said today that he attended Steenkamp's postmortem, and that she had three entrance wounds: one on the head, one in the elbow and one in the hip.

Describing the scene to the court, Botha said that the shots fired into the bathroom were aimed at the toilet bowl.

The shooter "would have to walk into the bathroom and turn directly at the door to shoot at the toilet the way the bullets went," he said.

Bulgarian government resigns amid growing protests

SOFIA (Reuters) - Bulgaria's government resigned on Wednesday after violent nationwide protests against high power prices, joining a long list of European administrations felled by austerity during Europe's debt crisis.

Prime Minister Boiko Borisov, a former bodyguard who swept to power in 2009 on pledges to root out corruption and raise living standards in the European Union's poorest member, now faces a tough task to prop up eroding support ahead of a probable early election.

Wage and pension freezes and tax hikes have bitten deep in a country where living standards 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".

On Tuesday, 11 people were hospitalized - including one man bleeding heavily from the head - and 11 arrested after protesters threw flares at police, who fought demonstrators with shields and truncheons.

"I will not participate in a government under which police are beating people," Borisov, who began his career guarding the Black Sea state's communist dictator Todor Zhivkov, said as he announced his resignation on Wednesday.

Parliament is expected to accept the resignation later in the day.

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's domineering manner and unpredictable decision making.

The prime minister made sacrifices in an attempt to cling on, sacking his finance minister, cutting power prices and risking a diplomatic row with the Czech Republic by punishing foreign-owned companies, a move that conflicted with EU norms on protection of investors and due process.

Borisov's rightist GERB party is the dominant faction in parliament but will not take part in talks to form a new government, Interior Minister Tsvetan Tsvetanov said, indicating that an election planned for July will now be held early.

"He made my day," student Borislav Hadzhiev, 21, in central Sofia said, commenting on Borisov's resignation. "The truth is that we're living in an extremely poor country."

IRE

GERB's popularity has held up well and it still leads, just, in the polls, largely because budget cutbacks have been relatively mild compared with those in many other European countries. Salaries and pensions were frozen rather than cut.

But the last opinion poll, taken before protests grew last weekend already showed the opposition Socialists were nearly tied with the ruling party and analysts said the protests had boosted the Socialists' chances.

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 and average salaries are stuck at around 800 levs ($550) a month.

Millions have emigrated in search of a better life, leaving swathes of the country depopulated and little hope for those who remain.

The measures announced this week has also put the country on a collision course with the EU and financial investors without easing the tension at home.

Czech Prime Minister Petr Necas demanded an explanation from Bulgaria and accused it of "politicizing" the power sector by threatening to revoke the electricity distribution license of central Europe's largest listed company CEZ, 70 percent of which is owned by the Czech state.

There have also been fines for another Czech company, Energo-Pro and Austria's EVN.

The precedent is unlikely to encourage other foreign investors, who already have to navigate complicated bureaucracy and widespread corruption and organized crime if they want to take advantage of Bulgaria's 16-percent flat tax rate.

"The resignation is the only responsible move," said Kantcho Stoychev, an analyst with pollster Gallup International. "It also gives Borisov some legitimacy to stay in political life in the future, despite the violent police actions last night."

Kurien writes to RS members on rape charges

NEW DELHI: Ahead of the Budget session of Parliament, Rajya Sabha Deputy Chairman P J Kurien has written to members of the House, saying three police inquiries and two judicial processes have cleared him in the 17-year-old Suryanelli rape case.

Kurien, who is under attack since the victim demanded recently that he be made an accused in the case, has attached an elaborate note on the sequence of events along with his appeal -- "kindly read in full and apply your judicious mind". The attempt by the senior Congress leader from Kerala to reach out to Rajya Sabha members assumes significance as it comes just ahead of the Budget session beginning tomorrow during which opposition is expected to rake up the issue with demands for his resignation.

The note titled "The Truth About Prof P J Kurien" reads-- "This false allegation was investigated three times by senior-level police officers (two under the Left Front governments). The Kerala high court has exonerated him and the Supreme Court confirmed the discharge in 2007. What more can Prof Kurien do to prove his innocence?" The note alleges that the CPI(M) was "propagating falsehood" by "trying to link" the recent Supreme Court judgment in the case to the exoneration given to Kurien by the Kerala high court which was upheld by the Supreme Court.

"The Supreme Court recently set aside the Kerala high court acquittal of 35 accused in the main Suryanelli case. It must be noted here that Prof Kurien was not at all an accused in this case," says the note. It says that the recent Supreme Court direction in the "main Suryanelli case" to Kerala High Court "does not involve (a) re-trial of the case, or (b) re-investigation of the case" and "it is only for re-hearing the appeal of the convicts, who were acquitted by the Kerala High Court".

"It is (a) reiterated that exoneration of Prof P J Kurien by the Kerala high court (in a private complaint filed by the girl) and the Kerala High Court's acquittal of the 35 accused persons, convicted by the trial court, were not linke at all," the note says.

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."

'Blade Runner' Denies Intentionally Killing Girlfriend

Olympian Oscar Pistorius today denied that he willfully killed his girlfriend, telling a South African court that he shot the woman through his bathroom door because he believed she was an intruder.

Pistorius, 26 and a double-amputee Olympian, was charged today with premeditated murder, or a Schedule 6 offense, which under South African law limits his chances for parole if convicted.

Pistorius, who gained worldwide fame for running on carbon-fiber blades and competing against able-bodied runners at the Olympics, is accused of shooting his girlfriend, Reeva Steenkamp, at his gated home in Pretoria, South Africa, Feb. 14.

PHOTOS: Paralympic Champion Charged in Killing

In a statement read by his lawyer, the runner said he and Steenkamp went to bed together before he was awoken by a noise he thought was an intruder coming from the bathroom.

Filled with a "sense of terror," he removed the 9-mm pistol he kept hidden under his bed and, without putting on his prosthetic legs, began shooting through the bathroom door, according to his statement.

It was only then that he realized Steenkamp was not in bed, he said in the statement. Fearing she was inside the bathroom, he says, he broke down the door using a cricket bat and carried the woman outside, where he called for help, and she soon died.

Pistorius appeared in court today for the first time since his Valentine's Day arrest, as prosecutors laid out their case, insisting that the runner could not have mistaken his girlfriend for an intruder.

"[Pistorius] shot and killed an innocent woman," Gerrie Nel, the senior state prosecutor, said in court, adding that there is "no possible explanation to support" the notion that Pistorius thought Steenkamp was an intruder.

Police responding to neighbors' calls about shouting and gunshots at Pistorius' home in the guarded and gated complex in the South African capital discovered Steenkamp's body. A 9-mm pistol was recovered at the home.

Prosecutors said Steenkamp had arrived at the house with the expectation of spending the night with Pistorius. They said that Steenkamp was shot while in the bathroom, which is about 21 feet from the main bedroom, and that the two rooms are linked by a passage. The door to the toilet was broken down from the outside, prosecutors said, implying that the bathroom door had been locked.

Prosecutors believe it's a case of premeditated murder because, they say, Pistorius had to stop, put on his prosthetic legs, grab a gun and then walk 21 feet to a bathroom.

The premeditated murder charge means that he would likely be sentenced to life in prison if convicted, and that he is likely to be denied bail, which is expected to be decided later today.

South Africa has moved away from the jury system, in light of its brutally racist past, so Pistorius' fate will rest in the hands of a judge and two magistrates.

The prosecution had said that the defense would no doubt argue for the charge to be downgraded to a Schedule 5 offense, but that was clearly wrong, according to the prosecution.

In a Schedule 5 offense, the onus is on the prosecution to prove that it would be in the interest of justice to keep the accused behind bars and not release him on bail. A Schedule 6 offense is a more serious category, wherein the defense has to prove that it would be in the interest of justice to release the accused person on bail.

Pistorius says no intentions to kill girlfriend

PRETORIA, South Africa (AP) — Oscar Pistorius told a packed courtroom Tuesday that he shot his girlfriend to death by mistake, thinking she was a robber. The prosecutor called it premeditated murder.

The double amputee said in an affidavit read by his lawyer at his bail hearing that he felt vulnerable because he did not have on his prosthetic legs when he pumped bullets into the locked bathroom door. Then, Pistorius said in the sworn statement, he realized that model Reeva Steenkamp was not in his bed.

"It filled me with horror and fear," he said.

He put on his prosthetic legs, tried to kick down the door, then bashed it in with a cricket bat to find Steenkamp, 29, shot inside. He said he ran downstairs with her, but "She died in my arms."

Prosecutor Gerrie Nel on Tuesday charged the 26-year-old athlete and Olympian with premeditated murder, alleging he took the time to put on his legs and walk some seven meters (yards) from the bed to the bathroom door before opening fire. A conviction of premeditated murder carries a mandatory sentence of life in jail.

The Valentine's Day shooting death has shocked South Africans and many around the world who idolized Pistorius for overcoming adversity to become a sports champion, competing in the London Olympics last year in track besides being a Paralympian. Steenkamp was a model and law graduate who made her debut on a South African reality TV program that was broadcast on Saturday, two days after her death.

The magistrate ruled that Pistorius faces the harshest bail requirements available in South African law.

Nel told the court that Pistorius fired into the door of a small bathroom where Steenkamp was cowering after a shouting match. He fired four times and three bullets hit Steenkamp, the prosecutor said.

"She couldn't go anywhere. You can run nowhere," prosecutor Nel argued. "It must have been horrific."

Pistorius sobbed softly as his lawyer, Barry Roux, insisted the shooting was an accident and that there was no evidence to substantiate a murder charge.

"Was it to kill her, or was it to get her out?" he asked about the broken-down door. "We submit it is not even murder. There is no concession this is a murder."

He said the state had provided no evidence that the couple quarreled nor offered a motive.

Nel rebutted: "The motive is 'I want to kill.'"

There were affadavits from friends of Pistorius and Steenkamp read out by defense lawyer Roux in the bail hearing.

The statements described a charming, happy couple. The night before the killing, they said, Pistorius and Steenkamp had canceled separate plans to spend the night before Valentine's Day together at his home.

As details emerged at the dramatic court hearing in the capital, Steenkamp's body was being cremated Tuesday at a memorial service in the south-coast port city of Port Elizabeth. The family said members had arrived from around the world. Six pallbearers carried her coffin, draped with a white cloth and covered in white flowers, into the church for the private service.

June Steenkamp, the mother, said the family wants answers.

"Why? Why my little girl? Why did this happen? Why did he do this?" she said in an interview published Monday in The Times newspaper.

Outside the court, several dozen singing women protested against domestic violence and waved placards urging Pistorius be refused bail. "Pistorius must rot in jail," one placard said.

South Africa has some of the world's worst rates of violence against females and the highest rate in the world of women killed by an intimate partner, according to a study by the Medical Research Council. Another council study estimates a child or woman is raped every four minutes. While homicide rates have dropped, the number of women killed by current or former partners has increased, said the council's Professor Rachel Jewkes. At least three women are killed by a partner every day in the country of 50 million, she said.

Steenkamp campaigned actively against domestic violence and had tweeted on Twitter that she planned to join a "Black Friday" protest by wearing black in honor of a 17-year-old girl who was gang-raped and mutilated two weeks ago.

What "she stood for, and the abuse against women, unfortunately it's gone right around and I think the Lord knows that statement is more powerful now," her uncle and the family spokesman Mike Steenkamp said after her memorial.

He said the family had planned a big get-together at Christmas but that had not been possible. "But we are here today as a family and the only one who's missing is Reeva," he said, breaking down and weeping.

Pistorius was born without fibula bones and had them amputated when he was 11 months.

The man known as the Blade Runner because of his running prostheses has lost several valuable sponsorships estimated to be worth more than $1 million a year.

On Tuesday, the athlete was ousted from a pro-gay campaign being launched in Cape Town, organizers said. In a video axed from the campaign, Pistorius says "You don't have to worry. You don't have to change. Take a deep breath and remember, 'It will get better.'"

SGX to review listing rules to protect retail investors of troubled firms

SINGAPORE: The Singapore Exchange (SGX) is looking at reviewing listing rules to better protect retail investors of troubled firms.

This was revealed in a letter to the Securities Investors Association (Singapore) (SIAS) from SGX deputy chief regulatory officer Richard Teng.

SGX was responding to SIAS' earlier proposals to safeguard investors of foreign issuers on the SGX.

The exchange said SIAS' proposals have been discussed and considered by its newly formed working committee to review the SGX listing rules.

Among the committee's proposals are to give SGX legal powers to appoint special auditors or other professionals to help or investigate troubled companies.

It added that there could also be a requirement that imposes a minimum notice period before board directors of listed companies can effectively resign.

In the meantime, SIAS said retail investors who own shares from foreign companies continue to face risks in recover their investments "should the untoward happen to any of the foreign issuers."

In a separate announcement, SGX said that it has formed a working committee to conduct a comprehensive review of the listing manual to enhance the robustness, efficacy and relevance of the listing framework in Singapore.

The new committee comprised capital market stakeholders, including representatives from the SGX, Association of Banks in Singapore, Singapore Institute of Directors, law firms, accounting firms and company secretarial firms.

The committee has commenced its review to identify areas of possible enhancements to strengthen Singapore's attractiveness as a capital market.

Dubai-based saviour of Youths suggstes information network for UAE goers

JALANDHAR: Dubai-based hotelier S P Singh Oberoi, who has returned with 17 Punjabi youths after saving them from gallows of Sharjah, has suggested to the NRI Sabha Punjab to have an "information and feedback offices" in every district of Punjab to guide youths who wanted to go to UAE for doing odd labour jobs.

During his visit to office of NRI Sabha Punjab, where he was felicitated on Monday late evening, Oberoi said that these offices of NRI Sabha should be approached by youths with names, addresses of the companies where the travel agents were assuring them to send and his UAE based organization 'Sarbat Da Bhalla' would get back within three days about the credentials of the companies.

"Most of the youths who go to UAE are from poor families and arrange loans to migrate there but when they don't get work in good companies or good salaries then they start trapped in illegal trades to save some money for repaying the loan," he said. "They are often misguided by travel agents and we can evolve a system of getting a reliable feedback from UAE then these youths can be saved from such entrapments which are leading them to jails," he said.

He said that several Punjabi youths were getting trapped in such illegal businesses and those he saved from gallows were caught there in similar conditions.
