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."

Autopsy confirms Mindy McCready's death as suicide

HEBER SPRINGS, Ark. (AP) — Authorities in Arkansas say preliminary autopsy results confirm country music singer Mindy McCready's death was a suicide.

The Cleburne County sheriff said in a statement Wednesday that preliminary autopsy results from Arkansas' state crime lab show McCready's death was a suicide from a single gunshot wound to the head.

Investigators have said McCready apparently shot and killed her late boyfriend's dog before she turned the gun on herself Sunday at her home in Heber Springs, Ark. Authorities found McCready's body and the dog on the front porch where her longtime boyfriend, musician David Wilson, died last month of a gunshot wound to the head.

Authorities are investigating Wilson's death as a suicide but haven't determined an official cause of death yet.

Office Depot to buy OfficeMax, really

Office Depot to buy Office Max as an attempt to compete with Staples.

Office Depot Inc. will buy Naperville-based Office Max Inc. in a $1.17 billion stock transfer, the companies announced Wednesday, ending nearly two hours of confusion about whether a deal had been reached

After days of speculation that a deal was close, a draft of a press release announcing the news was posted prematurely on Office Depot's website early Wednesday morning. More than an hour after it came out, there was still no mention of the merger on either company's website nor on the SEC or other investor websites. Sources cited by the New York Times Wednesday morning said negotiations were ongoing.

The companies then sent a joint statement at 9:30 a.m. EST that a deal had in fact been reached.

Office Depot will issue 2.69 new shares of common stock for each outstanding common share of OfficeMax. At Tuesday's closing prices, the deal is valued at $13.50 per share, or $1.17 billion, based on 86.7 million shares outstanding as of Oct. 26.

After the merger is completed, Office Depot's board will consist of an equal number of directors chosen by that company and OfficeMax.

Although the actual announcement didn’t go as planned, the deal has been rumored for years as the struggling office supply sector deals with fickle consumers and businesses that are conserving costs and doing more online.

Analysts say they expect far less pushback from antitrust authorities for this deal than what Office Depot faced in the 1990s, when it tried to merge with Staples, given the changes in the office supply market since then.

Underscoring how tough that business has become, Office Depot reported a fourth-quarter net loss, hurt by a 6 percent decrease in comparable sales at its North American stores and a revenue drop at its unit that serves North American businesses.

Office supply retailers, which are often seen as reflecting overall economic health, have suffered as demand for their products fell in the years after the last U.S. recession led companies to cut spending.

They also face strong competition from the likes of Amazon and Wal-Mart Stores Inc in selling everything from pens and notebooks to furniture and break room supplies to government, businesses and individuals.

SMALL PREMIUM

The offer represented a premium of just under 4 percent to OfficeMax's $13 close. It was not immediately clear if that was enough to satisfy one of the company's largest shareholders, Neuberger Berman, which said earlier this week it would support a deal depending on the terms.

OfficeMax shares rose 9.2 percent to $14.20 in premarket trading. Office Depot was up 10 percent at $5.52, meaning that OfficeMax was still trading below the value of the bid.

The deal, considered long overdue by many on Wall Street, will also give Office Depot and OfficeMax a chance to save hundreds of millions of dollars by closing stores, cutting advertising costs and streamlining their supply chain.

Industry experts have long hoped Office Depot would join hands with OfficeMax to take on Staples, which boosted its international business and clout with suppliers by buying Dutch rival Corporate Express in 2008.

BB&T Capital Markets analyst Anthony Chukumba said the Office Depot-OfficeMax combination would help Staples, however.

"Clearly, you can't make this deal work unless you close a bunch of stores," he said. "Store rationalization is long overdue, and Staples will clearly benefit from just having fewer stores to compete with."

Staples has 39.9 percent of the U.S. office supply market, Office Depot 19.2 percent and OfficeMax holds 15.7 percent, according to Euromonitor International.

2 teens die in Antioch crash: 'I just saw headlights spin'

Two teenagers were killed when their SUV crashed into a tree in Antioch in heavy rain, authorities said.

Joel Wittkamp, 16, and Ashley Seay, 17, were traveling west when their Chevrolet Trailblazer left the road in the 27000 block of Wilmot Road around 7 p.m. Monday, according to the Lake County sheriff's office. The SUV went through a yard before hitting the tree, the office said.

Both teens died on the scene. Joel, who was driving, was from Antioch and Ashley was from Lindenhurst, according to the Lake County coroner's office.

Authorities said they believe weather contributed to the crash. A man who lives where the crash occurred said it was raining hard when the accident occurred.

"It was pouring," said Tim Staples.

Staples said he was home when "I just saw the headlights spin ... We ran out and you could see the car was in the tree, the tree was on the car ... a mangled car I couldn't recognize."

"We checked the scene," he said. "We had flashlights and we looked inside. It didn't look promising, it looked really bad."

He said firefighters reached the scene in 7 or 8 minutes. "It took them an hour to get them out. They had to take the top of the car off."

Staples said the car hit a tree he had planted on his property 30 years ago.

Joel attended Antioch High School, officials said.

"We have counselors who are available," said Principal John Whitehurst. "Someone is following the young man’s schedule. If there were kids close to him, we are identifying who they are."

Whitehurst noted an earlier tragedy last November, when freshman Nicole Parfitt, 14, and her father were killed in a plane crash. "I know this is going to bring back some really unfortunate memories with kids intimately familiar with the incident," he said.

Ashley Seay came from a large family, with younger twin sisters and a few older siblings who have already graduated from Lakes Community High School, said Steve Plank, principal of the Lake Villa campus.

"There was a deep connection between the family, the school and community," he said.

Ashley was a cosmetology student who attended the high school until about noon, then spent her afternoons at the Lake County High Schools Technology Campus in Grayslake.

"That was a passion of hers," Plank said.

Counselors were available when classes began today, for students and staff.

"We have a number of faculty who are deeply affected by this, who have also needed support," he said. "It's kind of tough to come to school in the morning and realize there's a hole in your classroom."

At both high schools, an adult followed the schedule of Ashley and Joel, sitting in their seats for each class.

"We put an adult who is part of our human services team to sit in the seat," said Plank. "When kids show up to class and that seat is empty, it's a tough situation."

Burger King takes down Twitter account after hack attack

NEW YORK (Reuters) - Hackers breached the Twitter account of fast-food chain Burger King, posting the online equivalent of graffiti and sometimes making little sense.

Burger King Worldwide Inc suspended its Twitter account about an hour after it learned of the attack at 12:24 p.m. EST on Monday, company spokesman Bryson Thornton said in an email.

"It has come to our attention that the Twitter account of the BURGER KING® brand has been hacked," the company said in a statement. "We have worked directly with administrators to suspend the account until we are able to re-establish our legitimate site and authentic postings."

Several tweets carried the logo of Burger King's larger rival McDonald's, but spelled the latter company's name incorrectly. Others sought to tarnish Burger King, the third-largest U.S. hamburger chain, and its employees.

"Just got sold to McDonalds," one tweet said, adding "FREDOM IS FAILURE".

Pistorius: Thought lover an intruder in shooting

PRETORIA, South Africa (AP) — Oscar Pistorius wept Tuesday as his defense lawyer read the athlete's account of how he shot his girlfriend to death on Valentine's Day, claiming he had mistaken her for an intruder.

Prosecutors, however, told a packed courtroom that the double-amputee known as the Blade Runner intentionally and mercilessly shot and killed 29-year-old Reeva Steenkamp model as she cowered inside a locked bathroom.

Pistorius told the Pretoria Magistrate's Court at a bail hearing he felt vulnerable in the presence of an intruder inside the bathroom because he did not have on his prosthetic legs on, and fired into the bathroom door.

In a major point of contention that has already emerged, prosecutor Gerrie Nel said Pistorius took the time to put on his prostheses, walked seven meters (yards) from the bed to the enclosed toilet inside his bathroom and only then opened fire. Three of the bullets hit Steenkamp of the four that were fired into the door, Nel said.

Pistorius said in his sworn statement that after o0pening fire, he realized that Steenkamp was not in his bed.

"It filled me with horror and fear," Pistorius said. The 26-year-old Olympian said he put on his prosthetic legs and tried to kick down the door before finally giving up and bashing it in with a cricket bat. Inside, he said he found Steenkamp, slumped over. He said he lifted her bloodied body into his arms and tried to carry her downstairs to seek medical help.

But by then, it was too late.

"She died in my arms," the athlete said.

The Valentine's Day shooting death hocked 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.

Nel charged Pistorius with premeditated murder and said the athlete opened fire after they engaged in a shouting match.

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

A conviction of premeditated murder carries a mandatory sentence of life in jail.

Chief Magistrate Desmond Nair ruled that Pistorius must face the harshest bail requirements available in South African law. That means Pistorius' lawyers must offer "exceptional" reasons for the athlete to be free before trial, besides simply giving up his two South African passports and posting a cash bond.

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."

Pistorius' emotional outbursts again played a part in how the hearing progessed, as it did during an initial hearing Friday. At one point, Nair stopped the hearing after Pistorius wept as Roux read a portion of the athlete's statement describing how Steenkamp bought him a Valentine's Day present, but wouldn't let him open it the night before.

"Maintain your composure," the magistrate said. "You need to apply your mind here."

Pistorius' voice quivered when he answered: "Yes, my lordship."

Affidavits from friends of Pistorius and Steenkamp read out by Roux in the hearing described the two as a charming, happy couple. The night before the killing, they said, Pistorius and Steenkamp had canceled separate plans in order to spend the night before Valentine's Day together at his home, in a gated neighborhood of Pretoria.

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

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.

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 Mike Steenkamp, the family's spokesman, 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 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.'"

And Clarins Group, which owns Thierry Mugler Perfumes, said in an email that "out of respect and compassion for the families involved in this tragedy, Thierry Mugler Perfumes have taken the decision to withdraw all of their advertising campaigns featuring Oscar Pistorius."

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.

Clive Davis reveals in memoir that he's bisexual

NEW YORK (AP) — Record executive Clive Davis says he's bisexual.

In his new memoir, out Tuesday, the 80-year-old, who is twice divorced, reveals that he had sex with a man in the 1970s. Davis writes in "The Soundtrack of My Life" that he hadn't been repressed or confused during his marriages and that sex with a man "provided welcome relief."

He also writes that he started dating a man from 1990 to 2004, which he says was a "tough adjustment" for his son Mitchell. He says after "one trying year," he and his son worked things out. Davis is the father of three children.

Davis is the chief creative officer of Sony Music Entertainment. He writes that he's been in a "strong monogamous relationship" with a man for the last seven years.

2nd major hotel for McCormick Place

The agency that owns McCormick Place announced Tuesday that it will build a second hotel near the convention center complex, with plans calling for a 1,200-room facility that can serve as a headquarters for trade shows and conventions.

The Metropolitan Pier and Exposition Authority, also known as McPier, said it is acquiring land for the project, which will cost $400 million to build and will be located immediately west of the convention center's newest facility, the West Building. A skywalk would connect the two.

McPier is in talks with the site owners, affiliated with McHugh Construction Co., for the L-shaped parcel, said Jim Reilly, chief executive of the state-city authority.

"We think that will work out," he said. "If for some reason it doesn't, the city is prepared to use its eminent domain power. But we hope we won't have to do that."

He declined to comment on the potential deal cost, but said it would be a fraction of the construction cost. McPier and the site owners are discussing the possibility of a land swap, in which McPier would trade some land it owns on a nearby block.

A representative of McHugh Construction could not be reached for immediate comment.

The McPier proposal comes as key parcels just north of the West Building are moving toward auction. Those sites have been viewed as potential locations for more hotels and entertainment, and possibly an arena for DePaul University's Blue Demons basketball team.

Reilly declined to comment on where things stand in talks with DePaul. But he said McPier's latest hotel proposal would not stand in the way of other hotels being developed nearby, noting a 2009 study found potential demand for up to 8,000 hotel rooms in the area. The area will need some lower priced options too, he said. 

"I don't see this as competing (with other projects), he said. "This will give us 2,400 rooms, and we could easily use more than 2,400 rooms."

McPier owns the 800-room McCormick Place Hyatt Regency, which is undergoing a 460-room expansion due to be completed this summer at a cost of nearly $90 million.

The two hotels will operate cooperatively, McPier said. 

The latest project, to be between Indiana and Michigan, along the south side of Cermak, was announced jointly with Mayor Rahm Emanuel and Gov. Pat Quinn. Both said, in prepared statements, that the project would stimulate the local economy and make the city more competitive in the race for trade shows.

McPier will immediately seek proposals from design/build teams, hotel operators, and financial advisers and underwriters, Reilly said.  Construction should begin in the last quarter of 2014, with completion set for the end of 2016, he said.

As it did with its first hotel, McPier intends to finance the project in the construction phase through revenue bonds that would be paid back by hotel operating proceeds. At a later stage, it may add more financing through its expansion project debt structure, in which bonds are paid back with tourism taxes.

The hotel will have a Michigan Avenue address, which will connect it to the downtown in visitors' minds, and which should help foster entertainment development in the surrounding neighborhood, a historic strip known as Motor Row, Reilly said.

"I have long said I want there to be nightlife (in the area)," he said.

The hotel also would be two blocks from a planned new station on the CTA's green line, which should add to its appeal, he said.

International trade show visitors "love using mass transit," he said.

Country singer Mindy McCready dead in apparent suicide: officials

LITTLE ROCK, Arkansas —

Troubled country music star Mindy McCready, whose platinum singing career was shadowed by substance abuse and suicide attempts, was found dead on Sunday of an apparent self-inflicted gunshot wound, an Arkansas sheriff said. She was 37.

McCready's body was found on the porch of a house in Heber Springs, Arkansas, on Sunday afternoon. She was pronounced dead at the scene "from what appears to be a single self-inflicted gunshot wound," the Cleburne County Sheriff's Office said in a statement.

Deputies had been dispatched to the area following reports of "shots fired," the sheriff's office said.

McCready, whose albums include "Ten Thousand Angels" and "If I Don't Stay the Night," had a complicated personal life, marked by a history of substance abuse, suicide attempts, family disputes and tragedy

In January, the singer’s boyfriend, David Wilson, was found dead of an apparent self-inflicted gunshot wound. But questions surrounding the circumstances of the shooting led authorities to keep his death under investigation.  

In an interview with "Dateline" in late January, McCready denied any involvement in her live-in boyfriend's death after Canning asked her whether she had shot him.

"Oh my God, no. Oh my God, no," she responded. "He was my life. We were each other's life. There's no way to tell where one of us began and the other ended. We slept together every night holding hands."

Reaction to her death

For All-Star pitcher Roger Clemens issued a statement this morning that he heard McCready was trying to get "peace and in her life," according to USA Today. "The few times that I had met her and her manager/agent they were extremely nice," the statement read.

The New York Daily News in 2008 reported that Clemens and McCready had a decade-long affair that started when the singer was only 15. McCready never refuted the report, and in fact said she had "known Roger Clemens for a long time." Later, she confirmed the relationship with Clemens was sexual, but not until after she was 18.

Some fellow musicians paid tribute to McCready on Twitter as news of her death spread.

"My thoughts and prayers go out to Mindy McCready and her family today," country singer Tracy Lawrence tweeted.

Country star Carrie Underwood wrote, "I grew up listening to Mindy McCready... so sad for her family tonight. Many prayers are going out to them."

Born in Fort Myers, Florida, McCready learned to sing as a child at her local Pentecostal church. She moved to Nashville, Tennessee, to break into the country music business at the age of 18, according to allmusic.com.

She achieved early success with her 1996 debut album, "Ten Thousands Angels," which sold 2 million copies. Four other studio albums followed.

While successful in her career, McCready's personal life had begun to unravel in recent years.

In 2004 she was convicted of prescription drug fraud and placed on parole. Three years later she spent time in jail for violating her parole terms.

She had two young sons. Her first, Zander, was born in 2006. As her personal problems deepened, she became embroiled in a legal dispute over custody.

In November 2011, she left Florida with Zander and fled to Arkansas. McCready's mother, who had custody of the child, filed a missing person report against her daughter, and regained custody.

Her son with Wilson, Zayne, was born last year.

McCready appeared on the television show "Celebrity Rehab with Dr. Drew."

According to the biography posted on VH1's website as part of her appearance on the show, McCready said that she believed her only true addiction was to violent relationships.

In 2011 McCready appeared on HBO's show "Celebrity Close Calls" about life and death situations. That same year she also appeared on the network's "Celebrity Ghost Stories."

Her fifth album, "I'm Still Here," was released to acclaim in 2010.

The sheriff's office said McCready's body would be taken to the Arkansas State Crime Lab for an autopsy, adding that "the matter will be fully investigated."
