States' choices set up national health experiment


WASHINGTON (AP) — President Barack Obama's health care overhaul is unfolding as a national experiment with American consumers as the guinea pigs: Who will do a better job getting uninsured people covered, the states or the feds?


The nation is about evenly split between states that decided by Friday's deadline they want a say in running new insurance markets and states that are defaulting to federal control because they don't want to participate in "Obamacare." That choice was left to state governments under the law: Establish the market or Washington will.


With some exceptions, states led by Democrats opted to set up their own markets, called exchanges, and Republican-led states declined.


Only months from the official launch, exchanges are supposed to make the mind-boggling task of buying health insurance more like shopping on Amazon.com or Travelocity. Millions of people who don't have employer coverage will flock to the new markets. Middle-class consumers will be able to buy private insurance, with government help to pay the premiums in most cases. Low-income people will be steered to safety net programs like Medicaid.


"It's an experiment between the feds and the states, and among the states themselves," said Robert Krughoff, president of Consumers' Checkbook, a nonprofit ratings group that has devised an online tool used by many federal workers to pick their health plans. Krughoff is skeptical that either the feds or the states have solved the technological challenge of making the purchase of health insurance as easy as selecting a travel-and-hotel package.


Whether or not the bugs get worked out, consumers will be able to start signing up Oct. 1 for coverage that takes effect Jan. 1. That's also when two other major provisions of the law kick in: the mandate that almost all Americans carry health insurance, and the rule that says insurers can no longer turn away people in poor health.


Barring last-minute switches that may not be revealed until next week, 23 states plus Washington, D.C., have opted to run their own markets or partner with the Obama administration to do so.


Twenty-six states are defaulting to the feds. But in several of those, Republican governors are trying to carve out some kind of role by negotiating with federal Health and Human Services Secretary Kathleen Sebelius. Utah's status is unclear. It received initial federal approval to run its own market, but appears to be reconsidering.


"It's healthy for the states to have various choices," said Ben Nelson, CEO of the National Association of Insurance Commissioners. "And there's no barrier to taking somebody else's ideas and making them work in your situation." A former U.S. senator from Nebraska, Nelson was one of several conservative Democrats who provided crucial votes to pass the overhaul.


States setting up their own exchanges are already taking different paths. Some will operate their markets much like major employers run their health plans, as "active purchasers" offering a limited choice of insurance carriers to drive better bargains. Others will open their markets to all insurers that meet basic standards, and let consumers decide.


Obama's Affordable Care Act remains politically divisive, but state insurance exchanges enjoy broad public support. Setting up a new market was central to former Republican presidential candidate Mitt Romney's health care overhaul as governor of Massachusetts. There, it's known as the Health Connector.


A recent AP poll found that Americans prefer to have states run the new markets by 63 percent to 32 percent. Among conservatives the margin was nearly 4-1 in favor of state control. But with some exceptions, including Idaho, Nevada and New Mexico, Republican-led states are maintaining a hands-off posture, meaning the federal government will step in.


"There is a sense of irony that it's the more conservative states" yielding to federal control, said Sandy Praeger, the Republican insurance commissioner in Kansas, a state declining to run its own exchange. First, she said, the law's opponents "put their money on the Supreme Court, then on the election. Now that it's a reality, we may see some movement."


They're not budging in Austin. "Texas is not interested in being a subcontractor to Obamacare," said Lucy Nashed, spokeswoman for Gov. Rick Perry, who remains opposed to mandates in the law.


In Kansas, Praeger supported a state-run exchange, but lost the political struggle to Gov. Sam Brownback. She says Kansans will be closely watching what happens in neighboring Colorado, where the state will run the market. She doubts that consumers in her state would relish dealing with a call center on the other side of the country. The federal exchange may have some local window-dressing but it's expected to function as a national program.


Christine Ferguson, director of the Rhode Island Health Benefits Exchange, says she expects to see a big shift to state control in the next few years. "Many of the states have just run out of time for a variety of reasons," said Ferguson. "I'd be surprised if in the longer run every state didn't want to have its own approach."


In some ways, the federal government has a head start on the states. It already operates the Medicare Plan Finder for health insurance and prescription plans that serve seniors, and the Federal Employees Health Benefits Program. Both have many of the features of the new insurance markets.


Administration officials are keeping mum about what the new federal exchange will look like, except that it will open on time and people in all 50 states will have the coverage they're entitled to by law.


Joel Ario, who oversaw planning for the health exchanges in the Obama administration, says "there's a rich dialogue going on" as to what the online shopping experience should look like. "To create a website like Amazon is a very complicated exercise," said Ario, now a consultant with Manatt Health Solutions.


He thinks consumers should be able to get one dollar figure for each plan that totals up all their expected costs for the year, including premiums, deductibles and copayments. Otherwise, scrolling through pages of insurance jargon online will be a sure turn-off.

Cruise Ship Now Faces Expected Wave of Lawsuits












Despite having their feet back on solid ground and are making their way home, passengers from the Carnival Triumph cruise ship are still fuming over their five days of squalor on the stricken ship and the cruise ship company is likely to be hit with a wave of lawsuits.


"I think people are going to file suits and rightly so," maritime trial attorney John Hickey told ABCNews.com. "I think, frankly, that the conduct of Carnival has been outrageous from the get-go."


Hickey, a Miami-based attorney, said his firm has already received "quite a few" inquiries from passengers who just got off the ship early this morning.


"What you have here is a) negligence on the part of Carnival and b) you have them, the passengers, being exposed to the risk of actual physical injury," Hickey said.

The attorney said that whether passengers can recover monetary compensation will depend on maritime law and the 15-pages of legal "gobbledygook," as Hickey described it, that passengers signed before boarding, but "nobody really agrees to."


One of the ticket conditions is that class action lawsuits are not allowed, but Hickey said there is a possibility that could be voided when all the conditions of the situation are taken into account.


One of the passengers already thinking about legal action is Tammy Hilley, a mother of two, who was on a girl's getaway with her two friends when a fire in the ship's engine room disabled the vessel's propulsion system and knocked out most of its power.


"I think that's a direction that our families will talk about, consider and see what's right for us," Hilley told "Good Morning America" when asked if she would be seeking legal action.


While she said that she does not want to be greedy or exploit the situation, she does not feel that Carnival's $500 compensation is enough for the trauma passengers suffered.

"You talk about the emotional trauma and just last night, feeling what we went through last night while we were on land with our families and our insides just trembling," she said. "I don't think it begins to even say what is needed here."


In addition to the money, passengers will receive a full refund for the cruise, transportation expenses and vouchers for another cruise.


"We made our own nest [on deck] because we were just too terrified to go inside because of the smells and the germs, so we just banded together and made our own little nest and just survived," Hilley's friend Ann Barlow said.


Her friend Carolyn Klam said she got a stomach virus from drinking bad water once the power went out and friend Tammy Hilley said her cell phone was stolen this morning as the boat came into port.


"I think going back to our room was kind of traumatic and seeing that from day one we had no home, we were homeless," Hilley said. "We would go downstairs below deck and your feet could feel the sludge that you were walking through. The smells and the liquids draining from the ceiling and the stories of people sleeping in the hallways and the sanitary bags in the hallway, that was traumatic to just watch it start piling up."


The more than 4,000 passengers and crew began to disembark from the damaged ship around 10:15 p.m. CT Thursday in Mobile, Ala., amid cheers and tears. The last passenger left the ship at 1 a.m. CT, according to Carnival's Twitter handle.


Passenger Brandi Dorsett was thankful to be home, especially for her mother who was with her on the ship. Dorsett said she wasn't pleased with the doctor on staff.


"My mother is a diabetic, and they would not even come to the room because she cannot walk the stairs to help her with insulin. She hasn't had insulin in three days," Dorsett said.


The Carnival Triumph departed Galveston, Texas, last Thursday and lost power Sunday.

After power went out, passengers texted ABC News that sewage was seeping down the walls from burst plumbing pipes, carpets were wet with urine, and food was in short supply. Reports surfaced of elderly passengers running out of critical heart medicine and others on board squabbling over scarce food.


"It's degrading. Demoralizing, and then they want to insult us by giving us $500," Veronica Arriaga said after disembarking the ship.


As the ship docked, passengers lined the decks of the Triumph, waving and whistling to those on shore. "Happy V-Day" read a homemade sign made for the Valentine's Day arrival, while another sent a starker message: "The ship's afloat, so is the sewage."

Key U.S. general backs keeping Afghan forces at peak strength


WASHINGTON (Reuters) - The U.S. general nominated to oversee a vast region that includes Afghanistan on Thursday backed keeping Afghan forces at a peak strength of 352,000, contrary to current plans to shrink them after NATO declares the war over next year.


General Lloyd Austin, nominated to lead the U.S. military's Central Command, said at his Senate confirmation hearing that a more robust Afghan force, while more costly, would "hedge against any Taliban mischief" following America's longest war.


"Keeping the larger-size force would certainly reassure the Afghans, it would also reassure our NATO allies that we remain committed," Austin said.


The comments came two days after President Barack Obama announced in his State of the Union address that 34,000 U.S. troops - roughly half of the current U.S. force in Afghanistan - would be withdrawn by early 2014.


Obama reassured Americans that the costly, unpopular war was coming to an end, but he left unanswered bigger questions about America's exit strategy, including how many U.S. troops would stay in the country beyond 2014 to help train and advise the Afghans and to battle remnants of al Qaeda.


Obama also did not discuss the future size of the Afghan forces, although a White House fact sheet sent out after his address noted they would remain at 352,000 until "at least" early 2015.


Austin warned the Taliban would be waiting to test them.


"You could reasonably expect that an enemy that's been that determined, that agile, will very soon after we transition begin to try to test the Afghan security forces," Austin said.


Under current plans, the United States and its NATO allies will help build up the Afghan armed forces to 352,000 personnel, a number they are approaching, but the size of the force - which the allies will continue to fund - will be trimmed to 230,000 after 2015.


ECHOES OF IRAQ


The hearing frequently moved away from questions about the Afghan war and other current events to questions about Austin's past role as commander in Iraq, when a failure to strike an immunity deal for U.S. troops led to their total withdrawal in 2011.


Obama administration officials have warned that failure to strike an immunity deal with Afghanistan would also result in a pullout, but Afghan President Hamid Karzai and U.S. officials have expressed confidence a deal can be reached.


Republicans, who have criticized Obama's drawdown strategy in Afghanistan, noted that the president would have left a much smaller force in Iraq than Austin recommended, even if a deal had been struck.


Senator John McCain of Arizona lamented the lack of a U.S. presence in Iraq.


Pressed by Republicans, Austin acknowledged that the situation in Iraq was trending in a "problematic" direction, and agreed that a continued U.S. role would have helped bolster Iraqi forces.


When it came to Afghanistan, Senator Lindsay Graham of South Carolina warned Austin that if Obama sought an insufficient force for the post-2014 mission, he would refuse to vote for funding the war effort.


"It can be as low as 9 or 10,000, that I will stand with them," Graham said.


"If they overrule the commanders and create a force that cannot in my view be successful, I cannot in good conscience vote to continue this operation."


Graham said he would vote for Austin's confirmation once Austin spoke with the former commander of the Afghan mission, General John Allen, about his recommendations to Obama and reported back to the committee about his opinion.

US, UN urge Iran to ensure 'progress' at talks






WASHINGTON: Top US and EU leaders urged Iran on Thursday to help ensure "progress" in the next round of talks over its nuclear program, even as moves to boost UN inspections of Iranian sites failed.

US Secretary of State John Kerry cautioned the next negotiations, due on February 26 in Almaty, Kazakhstan, "can only make progress if the Iranians come to the table determined to make and discuss real offers."

And he warned as he met with UN chief Ban Ki-moon that the United States was determined not to get trapped in "a delay-after-delay process."

"Countries that have peaceful programs do not have problems proving to people that they are peaceful," Kerry told reporters.

"I think it is incumbent on the Iranians to prove that they are prepared to meet our willingness... to be open to a diplomatic resolution."

It took weeks of negotiations to agree on a date and venue for the next talks aimed at getting Tehran to rein in its nuclear enrichment program between the world powers, known as the P5+1, and Iran.

Ban also expressed hope that the P5+1 meetings would "bring fruitful progress."

And EU foreign policy chief Catherine Ashton, who met with Kerry separately Thursday at the State Department, said: "I always look for success... and I will do my best on behalf of the P5+1."

"It is important that we continue to track and make our efforts successful," she said.

But the chief UN atomic inspector said Thursday that separate talks with Iran had failed again to agree on enhanced inspections of its nuclear program.

"We had discussions on the structured approach document but could not finalize the document," Herman Nackaerts of the International Atomic Energy Agency told reporters after returning from Tehran.

"We will work hard now to resolve the remaining differences, but time is needed to reflect on the way forward."

Helicopter scam: Jaswant agrees change in specifications made during NDA rule

NEW DELHI: Even as the BJP kept up its attack on the government over alleged kickbacks in the VVIP chopper deal, senior party leader Jaswant Singh on Thursday agreed with former IAF chief S P Tyagi that the change in specifications of the helicopters was done at the behest of then national security adviser BrajeshMishra. Singh, however, defended the decision, saying it was done to avoid a single-vendor situation.

Singh also said the guilty in the matter was an Italian company and people had "forgotten them".

"We should not make wild allegations against a former IAF chief. It is not in the interest of both the air force and the country. The probe is on. As Mr Tyagi himself is saying, the probe should be held early. Why don't you agree to his suggestion," Singh told reporters.

Supporting Tyagi, who has been accused of taking bribes in the deal through his cousins, Singh said one should be careful while alleging "guilt through association". "Don't start judging people simply because of association or simply because former air chief marshal Tyagi has cousins who are also known as Tyagis," he said.

The former defence and external affairs minister added, "One of my own cousins, first cousin, he was known as a smuggler. Does that make me a smuggler? If another relative of mine commits a crime, does that make me a criminal?"

On its part, BJP demanded that the CBI probe into the Rs 3,600 crore deal should be monitored by a competent authority so that the investigation was not "delayed" as was done in the 2G case. "Ordering a mere CBI inquiry is not enough. It must be monitored. In the 2G spectrum case, CBI probe was ordered in 2009 but the agency did nothing for 15 months. It was only when the Supreme Court started monitoring the case suo motu that things started moving," party spokesperson Prakash Javadekar said.

He maintained that three questions were of utmost relevance in the probe -- when the order was placed, when the alleged kickbacks were paid and who recipients were.

Study: Fish in drug-tainted water suffer reaction


BOSTON (AP) — What happens to fish that swim in waters tainted by traces of drugs that people take? When it's an anti-anxiety drug, they become hyper, anti-social and aggressive, a study found. They even get the munchies.


It may sound funny, but it could threaten the fish population and upset the delicate dynamics of the marine environment, scientists say.


The findings, published online Thursday in the journal Science, add to the mounting evidence that minuscule amounts of medicines in rivers and streams can alter the biology and behavior of fish and other marine animals.


"I think people are starting to understand that pharmaceuticals are environmental contaminants," said Dana Kolpin, a researcher for the U.S. Geological Survey who is familiar with the study.


Calling their results alarming, the Swedish researchers who did the study suspect the little drugged fish could become easier targets for bigger fish because they are more likely to venture alone into unfamiliar places.


"We know that in a predator-prey relation, increased boldness and activity combined with decreased sociality ... means you're going to be somebody's lunch quite soon," said Gregory Moller, a toxicologist at the University of Idaho and Washington State University. "It removes the natural balance."


Researchers around the world have been taking a close look at the effects of pharmaceuticals in extremely low concentrations, measured in parts per billion. Such drugs have turned up in waterways in Europe, the U.S. and elsewhere over the past decade.


They come mostly from humans and farm animals; the drugs pass through their bodies in unmetabolized form. These drug traces are then piped to water treatment plants, which are not designed to remove them from the cleaned water that flows back into streams and rivers.


The Associated Press first reported in 2008 that the drinking water of at least 51 million Americans carries low concentrations of many common drugs. The findings were based on questionnaires sent to water utilities, which reported the presence of antibiotics, sedatives, sex hormones and other drugs.


The news reports led to congressional hearings and legislation, more water testing and more public disclosure. To this day, though, there are no mandatory U.S. limits on pharmaceuticals in waterways.


The research team at Sweden's Umea University used minute concentrations of 2 parts per billion of the anti-anxiety drug oxazepam, similar to concentrations found in real waters. The drug belongs to a widely used class of medicines known as benzodiazepines that includes Valium and Librium.


The team put young wild European perch into an aquarium, exposed them to these highly diluted drugs and then carefully measured feeding, schooling, movement and hiding behavior. They found that drug-exposed fish moved more, fed more aggressively, hid less and tended to school less than unexposed fish. On average, the drugged fish were more than twice as active as the others, researcher Micael Jonsson said. The effects were more pronounced at higher drug concentrations.


"Our first thought is, this is like a person diagnosed with ADHD," said Jonsson, referring to attention deficit-hyperactivity disorder. "They become asocial and more active than they should be."


Tomas Brodin, another member of the research team, called the drug's environmental impact a global problem. "We find these concentrations or close to them all over the world, and it's quite possible or even probable that these behavioral effects are taking place as we speak," he said Thursday in Boston at the annual meeting of the American Association for the Advancement of Science.


Most previous research on trace drugs and marine life has focused on biological changes, such as male fish that take on female characteristics. However, a 2009 study found that tiny concentrations of antidepressants made fathead minnows more vulnerable to predators.


It is not clear exactly how long-term drug exposure, beyond the seven days in this study, would affect real fish in real rivers and streams. The Swedish researchers argue that the drug-induced changes could jeopardize populations of this sport and commercial fish, which lives in both fresh and brackish water.


Water toxins specialist Anne McElroy of Stony Brook University in New York agreed: "These lower chronic exposures that may alter things like animals' mating behavior or its ability to catch food or its ability to avoid being eaten — over time, that could really affect a population."


Another possibility, the researchers said, is that more aggressive feeding by the perch on zooplankton could reduce the numbers of these tiny creatures. Since zooplankton feed on algae, a drop in their numbers could allow algae to grow unchecked. That, in turn, could choke other marine life.


The Swedish team said it is highly unlikely people would be harmed by eating such drug-exposed fish. Jonsson said a person would have to eat 4 tons of perch to consume the equivalent of a single pill.


Researchers said more work is needed to develop better ways of removing drugs from water at treatment plants. They also said unused drugs should be brought to take-back programs where they exist, instead of being flushed down the toilet. And they called on pharmaceutical companies to work on "greener" drugs that degrade more easily.


Sandoz, one of three companies approved to sell oxazepam in the U.S., "shares society's desire to protect the environment and takes steps to minimize the environmental impact of its products over their life cycle," spokeswoman Julie Masow said in an emailed statement. She provided no details.

Tempers and Compensation on Cruise Ship Rising













The 4,000 passengers and crew aboard the stricken Carnival Triumph cruise ship will disembark after dark tonight from the fetid cruiser dubbed "the poop deck" on social media, according to officials.


"It will come in. It will not stop," Alabama State Port Authority Director Jimmy Lyons said at a news conference today. "We're going to do everything we can from our standpoint to ensure that this is as smooth as possible."


He estimated the ship would arrive between 7 p.m. and 10 p.m. tonight.


Delighted passengers waved at media helicopters that flew out to film the ship and passenger Rob Mowlam told ABCNews.com by phone today that most of the passengers on board were "really upbeat and positive."


Nevertheless, when he gets off Mowlam said, "I will probably flush the toilet 10 times just because I can."


Mowlam, 37, got married on board the Triumph Saturday and said he and his wife, Stephanie Stevenson, 27, haven't yet thought of redoing the honeymoon other than to say, "It won't be a cruise."


Lyons said that with powerless "dead ships" like the Triumph, it is usually safer to bring them in during daylight hours, but, "Once they make the initial effort to come into the channel, there's no turning back."

"There are issues regarding coming into the ship channel and docking at night because the ship has no power and there's safety issues there," Richard Tillman of the Mobile Bay Convention and Visitors Bureau told ABCNews.com.


When asked if the ship could be disembarked in the dark of night, Tillman said, "It is not advised. It would be very unusual."


Carnival Cruise Senior Vice President of Marketing Terri Thornton, however, insisted during a news conference at the port of Mobile today, "Our understanding is it will be alongside this evening."


Thornton denied the rumors that there was a fatality on the ship. He said that there was one illness early on, a dialysis patient, but that passenger was removed from the vessel and transferred to a medical facility.


The U.S. Coast Guard is assisting now and there are multiple generators on board. And customs officials will board the ship while it is being piloted to port to accelerate the embarkation, officials said.


After eight miserable days at sea, the ship's owners have increased the compensation for what some on board are calling the vacation from hell.


All 3,143 passengers aboard the 900 foot colossus, which stalled in the Gulf of Mexico after an engine room fire early Sunday, were already being given a full refund for the cruise, transportation expenses and vouchers for a another cruise. Carnival Cruise Lines is now boosting that offer to include another $500 per person. Gerry Cahill, president and CEO of Carnival Cruise Lines, announced the additional compensation Wednesday.


"We know it has been a longer journey back than we anticipated at the beginning of the week under very challenging circumstances," he said in a statement. "We are very sorry for what our guests have had to endure. Therefore, in addition to the full refund and future cruise credit already offered, we have decided to provide this additional compensation."


Carnival also said that it has canceled a dozen planned voyages for the Triumph and acknowledged that the crippled ship had been plagued by other mechanical problems in the weeks before an engine-room fire left it powerless in the Gulf of Mexico.

EU must press ahead with bank oversight reforms: report






BRUSSELS: Europe has made real progress in setting up a single bank supervisory system but it is only a first step and provisions for winding up failed lenders and protecting depositors are urgently needed alongside it, a report prepared for the International Monetary Fund warned Wednesday.

In December, the eurozone agreed to set up a Single Supervisory Mechanism under the oversight of the European Central Bank as a first step toward a wider banking union, aiming to prevent any repeat of the debt crisis driven by the collapse of over-extended banks.

"Time is of the essence," with a banking union the "logical conclusion of the idea that integrated banking systems require integrated prudential oversight," said the report, written by IMF economists but which does not represent IMF policy.

Progress is necessary on all three elements -- supervision, winding up failed banks and depositor protection, it said, adding that the SSM must "ultimately supervise all banks".

The SSM negotiations were marked by sharp differences between France, which wanted all eurozone banks included, and Germany which wanted only several hundred of the biggest to be covered, at least initially.

Eurozone leaders also agreed on the need to set up a bank resolution and deposit protection system but there are concerns that with the debt crisis easing recently, the momentum for reform could slow.

The report said that if there is no provision for winding up banks and a safety net for depositors, "an SSM will do little to weaken vicious sovereign-bank links."

Failing banks were at the heart of the debt crisis as governments tried to keep them afloat with massive injections of capital, a step which only weakened their own financial position and in some cases, as in Ireland, forced them to seek an international bailout.

The report recommended that to head off fresh problems on this count, "it will be important to undertake as soon as possible direct recapitalisation of frail domestically systemic banks by the European Stability Mechanism."

The ESM, which became operational last year, is the eurozone's debt rescue backstop. Once the SSM is fully in place, expected by early 2014, the ESM will have the authority to intervene and inject funds into failing banks directly so as to head off any wider problems.

The report also picked up on importance of relations between the eurozone/SSM oversight system for the 17-nation eurozone and the 10 non-euro members, among them Britain which is home to one of the world's most important financial centres in London.

"A banking union is necessary for the euro area but accommodating the concerns of non-euro (members) ... will augur well for consistency with the EU single market," it said.

Clues to why most survived China melamine scandal


WASHINGTON (AP) — Scientists wondering why some children and not others survived one of China's worst food safety scandals have uncovered a suspect: germs that live in the gut.


In 2008, at least six babies died and 300,000 became sick after being fed infant formula that had been deliberately and illegally tainted with the industrial chemical melamine. There were some lingering puzzles: How did it cause kidney failure, and why wasn't everyone equally at risk?


A team of researchers from the U.S. and China re-examined those questions in a series of studies in rats. In findings released Wednesday, they reported that certain intestinal bacteria play a crucial role in how the body handles melamine.


The intestines of all mammals teem with different species of bacteria that perform different jobs. To see if one of those activities involves processing melamine, researchers from the University of North Carolina at Greensboro and Shanghai Jiao Tong University gave lab rats antibiotics to kill off some of the germs — and then fed them melamine.


The antibiotic-treated rats excreted twice as much of the melamine as rats that didn't get antibiotics, and they experienced fewer kidney stones and other damage.


A closer look identified why: A particular intestinal germ — named Klebsiella terrigena — was metabolizing melamine to create a more toxic byproduct, the team reported in the journal Science Translational Medicine.


Previous studies have estimated that fewer than 1 percent of healthy people harbor that bacteria species. A similar fraction of melamine-exposed children in China got sick, the researchers wrote. But proving that link would require studying stool samples preserved from affected children, they cautioned.


Still, the research is pretty strong, said microbiologist Jack Gilbert of the University of Chicago and Argonne National Laboratory, who wasn't involved in the new study.


More importantly, "this paper adds to a growing body of evidence which suggests that microbes in the body play a significant role in our response to toxicity and in our health in general," Gilbert said.

Charred Human Remains Found in Burned Cabin













Investigators have located charred human remains in the burned-out cabin where they believe suspected cop killer and ex-LAPD officer Christopher Dorner was holed up as the structure burned to the ground, police said.


The human remains were found within the debris of the burned cabin and identification will be attempted through forensic means, the San Bernardino County Sheriff-Coroner Department said in a news release early this morning.


Dorner barricaded himself in the cabin in the San Bernardino Mountains near Big Bear Tuesday afternoon after engaging in a gunfight with police, killing one officer and injuring another, the San Bernardino County Sheriff's Department said.


Cindy Bachman, a spokeswoman for the department, which is the lead agency in the action, said Tuesday night investigators would remain at the site all night.


FULL COVERAGE: Christopher Dorner Manhunt


When Bachman was asked whether police thought Dorner was in the burning cabin, she said, "Right. We believe that the person that barricaded himself inside the cabin engaged in gunfire with our deputies and other law enforcement officers is still inside there, even though the building burned."


Bachman spoke shortly after the Los Angeles Police Department denied earlier reports that a body was found in the cabin, contradicting what law enforcement sources told ABC News and other news organizations.


Police around the cabin told ABC News they saw Dorner enter but never leave the building as it was consumed by flames, creating a billowing column of black smoke seen for miles.


A news conference is scheduled for later today in San Bernardino.


One sheriff's deputy was killed in a shootout with Dorner earlier Tuesday afternoon, believed to be his fourth victim after killing a Riverside police officer and two other people this month, including the daughter of a former police captain, and promising to kill many more in an online manifesto.

Cops said they heard a single gunshot go off from inside the cabin just as they began to see smoke and fire. Later they heard the sound of more gunshots, which was the sound of ammunition being ignited by the heat of the blaze, law enforcement officials said.


Police did not enter the building, but shot tear gas inside.


One of the largest dragnets in recent history, which led police to follow clues across the West and into Mexico, apparently ended just miles from where Dorner's trail went cold last week.


It all began at 12:20 p.m. PT Tuesday, when a maid working at a local resort called 911, saying she and another worker had been tied up and held hostage by Dorner in a cabin, sources said.


The maid told police she was able to escape, but Dorner had stolen one of their cars, which was identified as a purple Nissan.


The San Bernardino Sheriff's Office and state Fish and Wildlife wardens spotted the stolen vehicle and engaged in a shootout with Dorner.


Officials say Dorner crashed the stolen vehicle and fled on foot only to commandeer Rick Heltebrake's white pickup truck on a nearby road a short time later.


"[Dorner] said, 'I don't want to hurt you, just get out and start walking up the road and take your dog with you.' He was calm. I was calm. I would say I was in fear for my life, there was no panic, he told me what to do and I did it," Heltebrake said.


"He was dressed in all camouflage, had a big assault sniper-type rifle. He had a vest on like a ballistic vest," Heltebrake added.


The white pickup truck bought Dorner extra time because police were still looking for the purple Nissan, California Department of Fish and Wildlife Lt. Patrick Foy told "Good Morning America" today.


"We were looking for a purple color Nissan and all of a sudden this white pickup starts coming by in the opposite direction. That's not the suspect's vehicle that we had been looking for," Foy said.


A warden with the Fish and Wildlife department noticed Dorner driving and the pursuit picked up again, Foy said.


"Ultimately, the officer who was driving that vehicle stopped and pulled out his patrol rifle and engaged probably 15 to 20 shots as Dorner was driving away," Foy said.


Dorner then ran on foot to the cabin in which he barricaded himself and got in a shootout with San Bernardino County sheriff's deputies and other officers who arrived.


The two deputies were wounded in the firefight and airlifted to a nearby hospital, where one died, police said. The second deputy was in surgery and was expected to survive, police said.


Police sealed all the roads into the area, preventing cars from entering the area and searching all of those on the way out. All schools were briefly placed on lockdown.


Believing that Dorner might have been watching reports of the standoff, authorities asked media not to broadcast images of police officers' surrounding the cabin, but sent him a message.


"If he's watching this, the message is: Enough is enough," Los Angeles Police Department spokesman Andy Smith told reporters at a news conference Tuesday. "It's time to turn yourself in. It's time to stop the bloodshed. It's time to let this event and let this incident be over."
