Greener planet is goal for 3 startups

If the glut of companies billing themselves as "solutions" providers is any indication, the world has no shortage of problems.

Green tech companies take on some of the most complicated, difficult problems to solve. They tend to be problems created by our mere existence, chief among them our massive demand for energy. The more we rely on energy to power our electronics, our vehicles and our lives, the more pollution we churn into our land, water and air.

The Tribune checked in with three local green tech startups at various stages of development. They haven't changed the world yet, but they're working on it.

COMPANY: LanzaTech

PROBLEM TO BE SOLVED: Global warming, a huge challenge as energy demand is expected to double within 40 years.

FUNDS RAISED: $100 million

It may sound like sci-fi, but LanzaTech produces gas-eating "bugs" that don't require oxygen to survive.

In April, the company's microscopic bacteria began ingesting carbon monoxide from a steel mill in China. Carbon monoxide goes in one end of the bacteria and ethanol comes out the other.

With a few genetic tweaks, the bug can produce a wide range of fuels and chemicals from gases that companies spend money to get rid of. The idea, says Jennifer Holmgren, the company's chief executive, is to trap nasty gases that float from steel mills, power plants and chemical factories, turning them into products that are useful and profitable.

The company recently inked a deal with Petronas, the national oil company of Malaysia, to develop a modified version of the bug that takes in carbon dioxide and produces acetic acid, a chemical companies need to produce polymers used in plastics.

"Rather than trying to sequester carbon deep into the earth, we will 'bury' it in a chemical," Holmgren said. "In this way, companies can not only comply with emissions reduction requirements, but also generate revenue along the way."

When Holmgren talks about the technology's potential, she pulls up a map of the world, showing partnerships and agreements the company has with companies from Boeing Co. in Chicago and Kansas-based Invista, the world's largest nylon producer, to Indian Oil Co. in New Delhi and Mitsui & Co. Ltd. in Japan.

Out of the company's various projects, the carbon monoxide-eating bacteria are the furthest along in the path toward commercialization. This month, LanzaTech finished a demonstration project for China's largest steel manufacturer, Baosteel, at a plant near Shanghai.

LanzaTech successfully produced the equivalent of more than 100,000 gallons of ethanol per year from just a fraction of the carbon monoxide the company creates in the steel-making process.

"You're literally driving for miles watching this steel mill," Holmgren said, explaining its vast size — and its potential to produce hundreds of millions of gallons of ethanol per year.

The technology creates a financial incentive to trap the gas rather than flare it, a common practice that produces carbon dioxide, which contributes to global warming. Through a series of pipes, the gas enters a vessel filled with the organism, which is floating in water. Fuel comes out the back end and is pumped through a distiller to create pure ethanol.

Because of the success of that demonstration, the steel company has ordered the first of what will eventually be three or four units, each about $80 million, that are each expected to produce 30 million to 50 million gallons of ethanol per year. Each unit pays itself back in under five years, Holmgren said.

"We don't want it to be green for green's sake. If it is, no one is going to use it," she said.

With 140 employees worldwide, LanzaTech doesn't have any revenues to report yet. Holmgren said LanzaTech expects to grow to profitability between 2013 and 2015.

Obama: 'Our hearts are broken'

A man killed his mother at their home and then opened fire Friday inside an elementary school, massacring 26 people, including 20 children, as youngsters cowered in fear to the sound of gunshots reverberating through the building and screams echoing over the intercom.

The 20-year-old killer, carrying at least two handguns, committed suicide at the school, bringing the death toll to 28, authorities said.

The rampage, coming less than two weeks before Christmas, was the nation's second-deadliest school shooting, exceeded only by the Virginia Tech massacre that claimed 33 lives in 2007.

"Our hearts are broken today," a tearful President Barack Obama, struggling to maintain his composure, said at the White House. He called for "meaningful action" to prevent such shootings, saying, "As a country, we have been through this too many times."

Police shed no light on the motive for the attack. The gunman, Adam Lanza, was believed to suffer from a personality disorder and lived with his mother, said a law enforcement official who was briefed on the investigation but was not authorized to discuss it.

Panicked parents looking for their children raced to Sandy Hook Elementary in Newtown, a prosperous New England community of about 27,000 people 60 miles northeast of New York City. Police told youngsters at the kindergarten-through-fourth-grade school to close their eyes as they were led from the building so that they wouldn't see the blood and broken glass.

Schoolchildren -- some crying, others looking frightened -- were escorted through a parking lot in a line, hands on each other's shoulders.

Law enforcement officials speaking on condition of anonymity said that Lanza killed his mother, Nancy Lanza, then drove to the school in her car with at least three guns, including a high-powered rifle that he apparently left in the back of the vehicle, and shot up two classrooms around 9:30 a.m.

A custodian ran through the halls, warning of a gunman on the loose, and someone switched on the intercom, alerting people in the building to the attack -- and perhaps saving many lives -- by letting them hear the hysteria going on in the school office, a teacher said. Teachers locked their doors and ordered children to huddle in a corner or hide in closets as shots echoed through the building.

Authorities gave no details on exactly how the attack unfolded, but police radio traffic indicated the shooting lasted only a few minutes. State police Lt. Paul Vance said officers arrived instantaneously, immediately entered the school, searched it completely and found Lanza dead.

In addition to the 20 children, six adults were killed at the school; the principal was believed to be among the dead. A woman who worked at Sandy Hook Elementary was wounded.

A law enforcement official speaking on condition of anonymity said investigators believe Lanza attended the school several years ago but appeared to have no recent connection to the place.

At least one parent said Lanza's mother was a substitute teacher there. But her name did not appear on a staff list. And the law enforcement official said investigators were unable to establish any connection so far between her and the school.

Lanza's older brother, 24-year-old Ryan, of Hoboken, N.J., was being questioned, but a law enforcement official said he was not believed to have had a role in the rampage. Investigators were searching his computers and phone records, but he told law enforcement he had not been in touch with his brother since about 2010.

The officials spoke on the condition of anonymity because they were not authorized to discuss the unfolding investigation.

At one point, a law enforcement official mistakenly identified the gunman as Ryan Lanza. Brett Wilshe, a friend of Ryan Lanza's, said Lanza told him the gunman may have had his identification. Ryan Lanza apparently posted Facebook page updates Friday afternoon that read, "It wasn't me" and "I was at work."

Robert Licata said his 6-year-old son was in class when the gunman burst in and shot the teacher. "That's when my son grabbed a bunch of his friends and ran out the door," he said. "He was very brave. He waited for his friends."

He said the shooter didn't utter a word.

Stephen Delgiadice said his 8-year-old daughter heard two big bangs. Teachers told her to get in a corner, he said. "It's alarming, especially in Newtown, Connecticut, which we always thought was the safest place in America," he said. His daughter was uninjured.

Owner of Rivera plane being investigated by DEA

PHOENIX (AP) — The company that owns a luxury jet that crashed and killed Latin music star Jenni Rivera is under investigation by the U.S. Drug Enforcement Administration, and the agency seized two of its planes earlier this year as part of the ongoing probe.

DEA spokeswoman Lisa Webb Johnson confirmed Thursday the planes owned by Las Vegas-based Starwood Management were seized in Texas and Arizona, but she declined to discuss details of the case. The agency also has subpoenaed all the company’s records, including any correspondence it has had with a former Tijuana mayor who U.S. law enforcement officials have long suspected has ties to organized crime.

The man widely believed to be behind the aviation company is an ex-convict named Christian Esquino, 50, who has a long and checkered legal past. Corporate records list his sister-in-law as the company’s only officer, but insurance companies that cover some of the firm’s planes say in court documents that the woman is merely a front and that Esquino is the one in charge.

Esquino’s legal woes date back decades. He pleaded guilty to a fraud charge that stemmed from a major drug investigation in Florida in the early 1990s and most recently was sentenced to two years in federal prison in a California aviation fraud case. Esquino, a Mexican citizen, was deported upon his release. Esquino and various other companies he has either been involved with or owns have also been sued for failing to pay millions of dollars in loans, according to court records.

The 43-year-old California-born Rivera died at the peak of her career when the plane she was traveling in nose-dived into the ground while flying from the northern Mexican city of Monterrey to the central city of Toluca early Sunday morning. She was perhaps the most successful female singer in grupero, a male-dominated Mexico regional style, and had branched out into acting and reality television.

It remained unclear Thursday exactly what caused the crash and why Rivera was on Esquino’s plane. The 78-year-old pilot and five other people were also killed. Esquino was not on the plane.

The late singer’s brother, Pedro Rivera Jr., said that he didn’t know anything about the owner or why or how she ended up in his plane.

Esquino told the Los Angeles Times in a telephone interview from Mexico City earlier this week that the singer was considering buying the aircraft from Starwood for $ 250,000 and the flight was offered as a test ride. He disputed reports that he owns Starwood, maintaining that he is merely the company’s operations manager “with the expertise.”

In response to an email from The Associated Press, Esquino said he did not want to comment. Calls to various phone numbers associated with him rang unanswered.

Esquino is no stranger to tangles with the law. He was indicted in the early 1990s along with 12 other defendants in a major federal drug investigation that claimed the suspects planned to sell more than 480 kilograms of cocaine, according to court records. He eventually pleaded guilty to conspiring to conceal money from the IRS and was sentenced to five years in prison, but much of the term was suspended for reasons that weren’t immediately clear.

He served about five months in prison before being released.

Cynthia Hawkins, a former assistant U.S. attorney who handled the case and is now in private practice in Orlando, remembered the investigation well.

“It was huge,” Hawkins said Thursday. “This was an international smuggling group.”

She said the case began with the arrest of Robert Castoro, who was at the time considered one of the most prolific smugglers of marijuana and cocaine into Florida from direct ties to Colombian drug cartels in the 1980s. Castoro was convicted in 1988 and sentenced to life in prison, but he then began cooperating with authorities, leading to his sentence being reduced to just 10 years, Hawkins said.

“Castoro cooperated for years,” she said. “We put hundreds of people in jail.”

He eventually gave up another smuggler, Damian Tedone, who was indicted in the early 1990s along with Esquino and 11 others in a conspiracy involving drug smuggling in Florida in the 1980s at a time when the state was the epicenter of the nation’s cocaine trade.

Tedone also cooperated with authorities and has since been released from prison. Telephone messages left Thursday for both Tedone and Castoro were not returned.

Esquino eventually pleaded guilty to the lesser offense of concealing money from the IRS.

Joseph Milchen, Esquino’s attorney at the time, said Thursday the case eventually revolved around his client “bringing money into the United States without declaring it.”

However, Milchen acknowledged that a plane purchased by Esquino was “used to smuggle drugs.”

He denied his former client has ever had anything to do with illegal narcotics.

“The only thing he has ever done is with airplanes,” Milchen said.

Court filings also indicate Esquino was sentenced to two years in federal prison after pleading guilty in 2004 to committing fraud involving aircraft he purchased in Mexico, then falsified the planes’ log books and re-sold them in the United States.

Also in 2004, a federal judge ordered him and one of his companies to pay a creditor $ 6.2 million after being accused of failing to pay debts to a bank.

As the years passed, Esquino’s troubles only grew.

In February this year, a Gulfstream G-1159A plane the government valued at $ 500,000 was seized by the U.S. Marshals Service on behalf of the DEA after landing in Tucson on a flight that originated in Mexico

Four months later, the DEA subpoenaed all of Starwood’s records dating to Dec. 13, 2007, including federal and state income tax documents, bank deposit information, records on all company assets and sales, and the entity’s relationship with Esquino and more than a dozen companies and individuals, including former Tijuana Mayor Jorge Hank-Rhon, a gambling mogul and a member of one of Mexico’s most powerful families. U.S. law enforcement officials have long suspected Hank-Rhon is tied to organized crime but no allegations have been proven. He has consistently denied any criminal involvement.

He was arrested in Mexico last year on weapons charges and on suspicion of ordering the murder of his son’s former girlfriend. He was later freed for lack of evidence.

The subpoena was obtained by the U-T San Diego newspaper.

A Starwood attorney listed on the subpoena, Jeremy Schuster, declined Thursday to provide details.

“We don’t comment on matters involving clients,” he said.

In September, the DEA seized another Starwood plane — a 1977 Hawker 700 with an insured value of $ 1 million — after it landed in McAllen, Texas, from a flight from Mexico.

Insurers of both aircraft have since filed complaints in federal court in Nevada seeking to have the Starwood policies nullified, in part, because they say Esquino lied in the application process when he noted he had never been indicted on drug-related criminal charges. Both companies said they would not have issued the policies had he been truthful.

Another attorney for Starwood has not responded to phone and email messages seeking comment, and no one was at the address listed at its Las Vegas headquarters. The address is a post office box in a shipping and mailing store located between a tuxedo rental shop and a supermarket in a shopping center several miles west of the Las Vegas Strip.

Life Expectancy Rises Around World, Study Finds

A sharp decline in deaths from malnutrition and infectious diseases like measles and tuberculosis has caused a shift in global mortality patterns over the past 20 years, according to a report published on Thursday, with far more of the world’s population now living into old age and dying from diseases mostly associated with rich countries, like cancer and heart disease.

Children in Nairobi, Kenya. Sub-Saharan Africa lagged in mortality gains, compared with Latin America, Asia and North Africa.

The shift reflects improvements in sanitation, medical services and access to food throughout the developing world, as well as the success of broad public health efforts like vaccine programs. The results are striking: infant mortality declined by more than half from 1990 to 2010, and malnutrition, the No. 1 risk factor for death and years of life lost in 1990, has fallen to No. 8.

At the same time, chronic diseases like cancer now account for about two out of every three deaths worldwide, up from just over half in 1990. Eight million people died of cancer in 2010, 38 percent more than in 1990. Diabetes claimed 1.3 million lives in 2010, double the number in 1990.

“The growth of these rich-country diseases, like heart disease, stroke, cancer and diabetes, is in a strange way good news,” said Ezekiel Emanuel, chairman of the department of medical ethics and health policy at the University of Pennsylvania. “It shows that many parts of the globe have largely overcome infectious and communicable diseases as a pervasive threat, and that people on average are living longer.”

In 2010, 43 percent of deaths in the world occurred at age 70 and older, compared with 33 percent of deaths in 1990, the report said. And fewer child deaths have brought up the mean age of death, which in Brazil and Paraguay jumped to 63 in 2010, up from 30 in 1970, the report said. The measure, an average of all deaths in a given year, is different from life expectancy, and is lower when large numbers of children die.

But while developing countries made big strides the United States stagnated. American women registered the smallest gains in life expectancy of all high-income countries’ female populations between 1990 and 2010. American women gained just under two years of life, compared with women in Cyprus, who lived 2.3 years longer and Canadian women who gained 2.4 years. The slow increase caused American women to fall to 36th place in the report’s global ranking of life expectancy, down from 22nd in 1990. Life expectancy for American women was 80.5 in 2010, up from 78.6 in 1990.

“It’s alarming just how little progress there has been for women in the United States,” said Christopher Murray, director of the Institute for Health Metrics and Evaluation, a health research organization financed by the Bill and Melinda Gates Foundation at the University of Washington that coordinated the report. Rising rates of obesity among American women and the legacy of smoking, a habit women formed later than men, are among the factors contributing to the stagnation, he said. American men gained in life expectancy, to 75.9 years from 71.7 in 1990.

Health experts from more than 300 institutions contributed to the report, which provided estimates of disease and mortality for populations in more than 180 countries. It was published in The Lancet, a British medical journal.

The World Health Organization issued a statement on Thursday saying that some of the estimates in the report differed substantially from those done by United Nations agencies, though others were similar. All comprehensive estimates of global mortality rely heavily on statistical modeling because only 34 countries — representing about 15 percent of the world’s population — produce quality cause-of-death data.

Sub-Saharan Africa was an exception to the trend. Infectious diseases, childhood illnesses and maternity-related causes of death still account for about 70 percent of the region’s disease burden, a measure of years of life lost due to premature death and to time lived in less than full health. In contrast, they account for just one-third in South Asia, and less than a fifth in all other regions. Sub-Saharan Africa also lagged in mortality gains, with the average age of death rising by fewer than 10 years from 1970 to 2010, compared with a more than 25-year increase in Latin America, Asia and North Africa.

Globally, AIDS was an exception to the shift of deaths from infectious to noncommunicable diseases. The epidemic is believed to have peaked, but still results in 1.5 million deaths each year.

Over all, the change means people are living longer, but it also raises troubling questions. Behavior affects people’s risks of developing cancer, heart disease and diabetes, and public health experts say it is far harder to get people to change their ways than to administer a vaccine that protects children from an infectious disease like measles.

“Adult mortality is a much harder task for the public health systems in the world,” said Colin Mathers, a senior scientist at the World Health Organization.

Tobacco use is a rising threat, especially in developing countries, and is responsible for almost six million deaths a year globally. Illnesses like diabetes are also spreading fast.

Push for minimum wage hike intensifies

NEW YORK — Before the recession, Amie Crawford was an interior designer, earning $50,000 a year patterning baths and cabinets for architectural firms.

Now, she's a "team member" at the Protein Bar in Chicago, where she makes $8.50 an hour, slightly more than minimum wage. It was the only job she could find after months of looking. Crawford, now 56, says she needed to take the job to stop the hemorrhaging of her retirement accounts.

In her spare time, Crawford works with a Chicago group called Action Now, which is staging protests to raise the minimum wage in a state where it hasn't been raised since 2006.

"Thousands of workers in Chicago, let alone in the rest of the country, deserve to have a livable wage, and I truly believe that when someone is given a livable wage, that is going to bolster growth in communities," she said.

If it seems that workers such as Crawford are more prevalent these days, protesting outside stores including Wal-Mart, McDonald's and Wendy's to call for higher wages, it may be because there are more workers in these jobs than there were a few years ago.

Quiz: How much do you know about the 'fiscal cliff'?

Of the 1.9 million jobs created during the recovery, 43% of them have been in the low-wage industries of retail, food services and employment services, whose workforces include temporary employees who often work part time and without benefits or health insurance, according to a study by Annette Bernhardt, policy co-director of the National Employment Law Project in New York.

At the same time, many workers such as Crawford who have been displaced from their jobs are experiencing significant earnings losses after getting a new job. About one-third of the 3 million workers displaced from their jobs from 2009 to 2011 and then reemployed said their earnings had dropped 20% or more, according to the Bureau of Labor Statistics.

"What these protests are signaling are that working families are at breaking point after three decades of rising inequality and stagnant wages," Bernhardt said.

The rise of low-paying jobs in the recovery, experts said, has cut the spending power of workers who once worked in middle-class occupations. Construction workers who made $30 an hour, for example, during the housing boom may now find themselves working on a temporary basis.

"You see workers trading down their living standards," said Joseph Brusuelas, a senior economist for Bloomberg who studies the U.S. economy.

Now, Brusuelas said, there's an oversupply of workers and they're willing to take any job in a sluggish economy, even if they're overqualified. That includes temporary jobs without benefits, and minimum wage positions such as the one Crawford took.

Although the 2012 election might have brought the idea of income inequality to the forefront of voters' minds, efforts to increase wages for these workers are sputtering in an era of austerity when businesses say they are barely hiring, much less paying workers more.

The New Jersey state legislature handed Gov. Chris Christie a bill to raise the state's minimum wage to $8.50 an hour from the federal minimum of $7.25 this month, but he hasn't signed it and has signaled he might not. An earlier effort in New Jersey to tie the minimum wage to the consumer price index was vetoed by the governor.

Democratic lawmakers in Illinois are also trying to push a bill that would increase the minimum wage — an earlier effort this year failed. The Legislature last voted to raise its minimum wage in 2006, before the recession, and the governor agreed.

"A higher minimum wage means a person has to pay more for each worker," said Ted Dabrowski, vice president of policy at the Illinois Policy Institute, which opposes raising the minimum wage. "Companies have a few choices — increase prices, reduce the number of people they hire, cut employee hours or reduce benefits. When employees become too expensive, they have no choice but to reduce the number of workers."

The Center for Economic and Policy Research in Washington, D.C., however, says there is little indication from economic research that increases in the minimum wage lead to lower employment, and, because higher wages mean workers have more money to spend, employment can actually increase.

A bill to raise the federal minimum wage was introduced to the U.S. Senate by Tom Harkin (D-Iowa) in July and referred to committee, where it has sat ever since.

"Business lobbyists are aware of the campaign and are aggressively working to stop it," said Madeline Talbott, the former lead organizer of Chicago's Action Now. "We've had a hard time getting our legislature to approve it."

But Talbott and other advocates say that the protests that have spread throughout Illinois and the country in recent weeks might force the issue to its head.

"You saw it happening 18 months ago when Occupy started — workers are now realizing that they have rights too in the workplace," said Camille Rivera, executive director of United NY, one of the groups working to raise the minimum wage in New York. "It's a good time for us to be fighting these issues, when companies are making millions of dollars in profits."

The protests are bringing out people who might not usually participate, including Marcus Rose, 33. Rose, who has worked the grill at a Wendy's for 21/2 months, was marching outside that Wendy's in Brooklyn recently on a day of protests, responding as organizers shouted lines such as "Wendy's, Wendy's, can't you see, $7.25 is not for me."

"If you don't stand up for nothing, you can't fall for anything," he said.

Talbott, the Action Now organizer, says that people such as Rose may make a difference in whether lawmakers at the state and national level will listen to the protests. The Obama victory energized the working class to believe that they could fight against big-money interests and win, she said.

"It comes down to the traditional situation — whether the power is in the hands of organized money or of organized people," she said. "The organized money side tends to win, but it doesn't have to win. The more people you are, the more chance you have against money."

Smokestack victim's aunt: 'He was a very happy-go-lucky kid'

Chicago firefighter Kevin Krasneck talks about the rescue attempt of Nicholas Wieme, who died after falling down the Hotel Intercontinental's smokestack.

Nicholas Wieme loved making short films when he was growing up in a small town in Minnesota, a theatrical passion that would lead him to Chicago.

On Wednesday evening, the 23-year-old climbed onto the roof of the InterContinental Chicago hotel, with its famed onion-shaped dome, to take photographs when the night went terribly wrong.

Wieme fell into a smokestack and became wedged, beginning an elaborate, hourslong rescue attempt by firefighters that ultimately proved futile.

Friends and family mourned Thursday a young man they said was a creative force, an aspiring comedian and improv actor who had so impressed his coaches at iO Chicago, an improv theater, that they made him a regular on a team.

"He was a force to watch. He was a terrific artist," said Matt Higbee, Wieme's coach at iO Chicago for the last eight months.

Wieme, who lived on the North Side, had been dining with a friend at Michael Jordan's restaurant in the Michigan Avenue hotel when, police said, they decided to "explore" the building. Wieme and the woman took an elevator to the top floor and walked onto the rooftop deck, a restricted area, through an unsecured door, officials said.

Firefighters later learned that Wieme had fallen down the smokestack, according to Fire Department spokeswoman Meg Ahlheim.

Firefighters wrapped ropes around a structure in the roof dome and lowered a single man, a firefighter/paramedic, to Wierme's aid, and determined he was unconscious.

Crews used an electric handsaw to drill through the quarter-inch steel duct on the 39th floor, stirring up dust from insulation and soot from years of chimney buildup. They secured two wooden planks that would stop Wieme if he fell further, officials said.

"It turned very precarious because two feet after where we made the hole was a drop that would have went 42 floors to the basement," Special Operations Chief Michael Fox said. "So it took us a little time to cut the hole in the right spot and shore it up so when we brought him out he would not fall into the basement."

The paramedic in the chimney secured Wieme to a rescue board attached to a rope, and firefighters slowly lowered him to crews on the 39th floor. He was pulled out of the chimney just after 4:30 a.m. and taken to Northwestern Memorial Hospital. There, he was pronounced dead at 5:15 a.m. An autopsy will be conducted Friday.

Raymond Vermolen, general manager of the hotel, released a statement saying InterContinental "holds the safety, comfort and well-being of our guests and employees as our top priority and concern. Our thoughts and prayers are with the family and friends of the guest at this difficult time. The hotel staff will continue to cooperate fully with authorities in their investigation. All further questions should be directed to the Chicago Police Department."

Friends and family recalled Thursday how Wieme had long wanted to be a performer and later a director, and started making his own films when he was 16. Wieme grew up in Pipestone, Minn., a small town near the South Dakota border, the son of a radio announcer. There he worked in the town's movie theater.

"I think that's what sparked him," said his aunt, Linda Wieme, of Balaton, Minn.

Linda Wieme said his comedy reflected his character.

"He was a bubbly kid. I don't think I ever saw him upset," she said. "He always had some joke or something to lift your spirits. ... That's the reason he was a comedian, he was a very happy-go-lucky kid."

His brother Jamie Wieme said Nick "began taking up the hobby of stand-up comedy" while at Minnesota State University in Moorhead. Comedy led to acting, which led to Chicago and the improv scene, his brother said.

"Those that watched him perform often attested that Nick had a way of unintentionally stealing the show," his brother told the Minneapolis Star Tribune. Wieme had fierce loyalty to his family and friends and would do anything for anyone, he said.

Higbee said he first noticed Wieme when he was affiliated with iO as a student and saw him earn a coveted spot there as a performer.

"He had such a joyousness," Higbee added, "and you couldn't help but watch him."

Wieme is survived by his parents, two brothers, a sister-in-law and a niece.

Tribune reporter Jeremy Gorner and Minneapolis Star Tribune reporter Paul Walsh contributed.

Facebook, Google tell the government to stop granting patents for abstract ideas

Facebook (FB), Google (GOOG) and six other tech companies have petitioned the courts to begin rejecting lawsuits that are based on patents for vague concepts rather than specific applications, TechCrunch reported. The agreement, which was cosigned by Zynga (ZNGA), Dell (DELL), Intuit (INTU), Homeaway (AWAY), Rackspace (RAX), and Red Hat (RHT), notes the only thing these abstract patents do is increase legal fees and slow innovation in the industry. The companies claim that “abstract patents are a plague in the high tech sector” and force innovators into litigation that results in huge settlements or steep licensing fees for technology they have already developed on their own, which then leads to higher prices for consumers.

“Many computer-related patent claims just describe an abstract idea at a high level of generality and say to perform it on a computer or over the Internet,” the briefing reads. “Such barebones claims grant exclusive rights over the abstract idea itself, with no limit on how the idea is implemented. Granting patent protection for such claims would impair, not promote, innovation by conferring exclusive rights on those who have not meaningfully innovated, and thereby penalizing those that do later innovate by blocking or taxing their applications of the abstract idea.”

The companies conclude, “It is easy to think of abstract ideas about what a computer or website should do, but the difficult, valuable, and often groundbreaking part of online innovation comes next: designing, analyzing, building, and deploying the interface, software, and hardware to implement that idea in a way that is useful in daily life. Simply put, ideas are much easier to come by than working implementations.”

Paper Links Nerve Agents in ’91 Gulf War and Ailments

Reviving a 20-year debate over illnesses of veterans of the 1991 Persian Gulf war, a new scientific paper presents evidence that nerve agents released by the bombing of Iraqi chemical weapons depots just before the ground war began could have carried downwind and fallen on American troops staged in Saudi Arabia.

The paper, published in the journal Neuroepidemiology, tries to rebut the longstanding Pentagon position, supported by many scientists, that neurotoxins, particularly sarin gas, could not have carried far enough to sicken American forces.

The authors are James J. Tuite and Dr. Robert Haley, who has written several papers asserting links between chemical exposures and gulf war illnesses. They assembled data from meteorological and intelligence reports to support their thesis that American bombs were powerful enough to propel sarin from depots in Muthanna and Falluja high into the atmosphere, where winds whisked it hundreds of miles south to the Saudi border.

Once over the American encampments, the toxic plume could have stalled and fallen back to the surface because of weather conditions, the paper says. Though troops would have been exposed to low levels of the agent, the authors assert that the exposures may have continued for several days, increasing their impact.

Though chemical weapons detectors sounded alarms in those encampments in the days after the January 1991 bombing raids, they were viewed as false by many troops, the authors report.

But a significant number of medical experts have cast doubts on the sarin gas theory over the years, and several said Thursday that the new paper did little to change their minds.

Dr. John Bailar, an emeritus professor at the University of Chicago who led a group that studied gulf war illnesses in 1996, said there was still no clear evidence that troops might have been exposed to levels of sarin significant enough to have a biological effect.

Dr. Bailar said that the stress of war rather than chemical agents might be a more likely cause of the veterans’ problems. “Gulf war syndrome is real,” he said, using the term for a constellation of symptoms. “And the veterans who have it deserve appropriate medical care. But we should not kid ourselves about its causes or about the most effective means of treatment.”

Nearly half of the 700,000 service members who were deployed in 1990 and 1991 for the gulf war have filed disability claims with the Department of Veterans Affairs, and more than 85 percent of those have been granted benefits, the department has reported.

Many of those veterans have reported long-lasting problems, including chronic pain, memory loss, persistent fatigue and diarrhea, some of which had no clear causes. Many veterans insist that their problems are not the result of stress but have a biological basis.

Paul Sullivan, a gulf war veteran who has advocated for more research into the illnesses, said the new paper provided “overwhelming scientific evidence” that exposure to chemical agents sickened those troops and that the Department of Veterans Affairs should ensure that all receive health care and benefits.

Panels of medical experts have come down on both sides of the issue, with one group in 2000 questioning whether low levels of sarin could cause long-term health problems and another in 2004 concluding that toxic chemicals had caused neurological damage in many troops.

The Pentagon has acknowledged that the postwar demolition of a chemical weapons depot at Kamisiya, in southern Iraq, may have exposed 100,000 troops to nerve gas. But the military has said it was unlikely that nerve gas caused long-term illnesses in troops, a position it reiterated on Thursday.

Illinois foreclosures up for 11th month

Foreclosure activity in Illinois posted the 11th straight year-over-year increase in November, but compared with a month earlier, filings are trending in the right direction, according to new data released Thursday.

RealtyTrac said the 13,520 properties within the state that received a foreclosure notice last month was a decrease of 9 percent from October but up 9 percent from November 2011. last month's activity, which equated to one out of every 392 homes in the state receiving a notice, gave Illinois the nation's third-highest state foreclosure rate, surpassed by only Florida and Nevada.

In the Chicago-area counties of Cook, DuPage, Kane, Kendall, Lake and Will, almost 11,000 homes received a foreclosure notice in November, a decrease of 10.5 percent from October's level of activity but up 1.6 percent from November 2011

Most of that activity was in Cook County, where about 2,299 homes received initial notices of default, another 2,651 homes were scheduled for court-ordered sales and 2,086 homes were repossessed by lenders.

Among the nation's metropolitan areas, Rockford and Chicago ranked 11th and 13th, respectively, in terms of their foreclosure rates.

Nationally, the number of homes that were repossessed by lenders and became bank-owned rose on a year-over-year basis for the first time  since October 2010, the company said. In November, more than 59,000 homes across the country were repossessed, an increase of 11 percent from October and 5 percent from November 2011.

"The drop in overall foreclosure activity in November was caused largely by a 71-month low in foreclosure starts for the month, more evidence that we are past the worst of the foreclosure problem brought about by the housing bubble bursting six years ago," said Daren Blomquist, a company vice president. "But foreclosures are continuing to hobble the U.S. housing market as lenders finally seize properties that started the process a year or two ago, and much longer in some cases."
