False memories prime immune system for future attacks

IN A police line-up, a falsely remembered face is a big problem. But for the body's police force – the immune system – false memories could be a crucial weapon.

When a new bacterium or virus invades the body, the immune system mounts an attack by sending in white blood cells called T-cells that are tailored to the molecular structure of that invader. Defeating the infection can take several weeks. However, once victorious, some T-cells stick around, turning into memory cells that remember the invader, reducing the time taken to kill it the next time it turns up.

Conventional thinking has it that memory cells for a particular microbe only form in response to an infection. "The dogma is that you need to be exposed," says Mark Davis of Stanford University in California, but now he and his colleagues have shown that this is not always the case.

The team took 26 samples from the Stanford Blood Center. All 26 people had been screened for diseases and had never been infected with HIV, herpes simplex virus or cytomegalovirus. Despite this, Davis's team found that all the samples contained T-cells tailored to these viruses, and an average of 50 per cent of these cells were memory cells.

The idea that T-cells don't need to be exposed to the pathogen "is paradigm shifting," says Philip Ashton-Rickardt of Imperial College London, who was not involved in the study. "Not only do they have capacity to remember, they seem to have seen a virus when they haven't."

So how are these false memories created? To a T-cell, each virus is "just a collection of peptides", says Davis. And so different microbes could have structures that are similar enough to confuse the T-cells.

To test this idea, the researchers vaccinated two people with an H1N1 strain of influenza and found that this also stimulated the T-cells to react to two bacteria with a similar peptide structure. Exposing the samples from the blood bank to peptide sequences from certain gut and soil bacteria and a species of ocean algae resulted in an immune response to HIV (Immunology, doi.org/kgg).

The finding could explain why vaccinating children against measles seems to improve mortality rates from other diseases. It also raises the possibility of creating a database of cross-reactive microbes to find new vaccination strategies. "We need to start exploring case by case," says Davis.

"You could find innocuous pathogens that are good at vaccinating against nasty ones," says Ashton-Rickardt. The idea of cross-reactivity is as old as immunology, he says. But he is excited about the potential for finding unexpected correlations. "Who could have predicted that HIV was related to an ocean algae?" he says. "No one's going to make that up!"

US cruise ship passengers' parting gift: bathrobes

WASHINGTON: The 4,000-plus exhausted passengers who lived a hellish four-day ordeal aboard the powerless and drifting Carnival Triumph cruise ship won't be left completely empty handed.

The cruise company is making a gift to the travelers of the bathrobes they were using on the ship, the company announced Friday.

"Of course the bathrobes for the Carnival Triumph are complimentary," it said in a tweet on the official @carnivalcruise account.

But the announcement has been received with less than full-throated cheers.

"Who wants a stinky robe?!" tweeted a reporter in North Carolina, Astrid Martinez, while another user of the social media site, Natalie Eshaya, enthused sarcastically, "Oh how generous."

Another skeptic, Paul Nather, wondered "What do you think the going rate for a Carnival cruise bathrobe will be on eBay tomorrow?"

The white bathrobe has become an unlikely symbol of the nightmare of the cruise-goers, who donned them to attract attention as they stood on the drifting ship.

Others used the white terrycloth as a canvas to write messages, with one passenger proclaiming, "I survived Carnival's triumph redbags" -- a reference to the bags that substituted for toilets.

The Triumph docked Friday morning in the port of Mobile, Alabama. It had originally been scheduled to return to port early Monday after a weekend stop in Cozumel in Mexico, before an engine room blaze left the massive vessel without electricity to power the kitchens, toilets, and other necessities.

Man arrested in Alaska Coast Guard base deaths

ANCHORAGE, Alaska An Alaska man was arrested Friday in last year's shooting deaths at a Coast Guard air station on Kodiak Island that left two employees dead, the U.S. attorney said.

James Michael Wells of Kodiak is accused in a federal murder complaint of killing Petty Officer 1st Class James Hopkins and retired Chief Boatswain's Mate Richard Belisle on April 12.

Another Coast Guard member found the victims shortly after the two would have arrived for work at the station, which monitors radio traffic from ships and planes and is home to cutters, helicopters and rescue swimmers that aid mariners in the Bering Sea and Pacific Ocean. Their bodies were found in the rigger building, where antennas are repaired.

FBI agents immediately flew to Kodiak Island from Anchorage, about 250 miles away, to investigate the case as a double homicide. Few details were released in the weeks after the deaths.

Wells' arrest came after "an extensive investigation" led by the FBI and the Coast Guard Investigative Service, with help from the Alaska State Troopers, U.S. Attorney Karen Loeffler said in a statement.

Wells is expected to appear in court next week in Anchorage, Loeffler said.

No one was immediately reachable by phone Friday evening at the U.S. attorney's office to provide additional details.

Hopkins, 41, was an electronics technician from Vergennes, Vt. Belisle, 51, was a former chief petty officer who continued service to the Coast Guard as a civilian employee.

Carnival Cruise Ship Hit With First Lawsuit

The first lawsuit against Carnival Cruise Lines has been filed and it is expected to be the beginning of a wave of lawsuits against the ship's owners.

Cassie Terry, 25, of Brazoria County, Texas, filed a lawsuit today in Miami federal court, calling the disabled Triumph cruise ship "a floating hell."

"Plaintiff was forced to endure unbearable and horrendous odors on the filthy and disabled vessel, and wade through human feces in order to reach food lines where the wait was counted in hours, only to receive rations of spoiled food," according to the lawsuit, obtained by ABCNews.com. "Plaintiff was forced to subsist for days in a floating toilet, a floating Petri dish, a floating hell."

The filing also said that during the "horrifying and excruciating tow back to the United States," the ship tilted several times "causing human waste to spill out of non-functioning toilets, flood across the vessel's floors and halls, and drip down the vessel's walls."

Terry's attorney Brent Allison told ABCNews.com that Terry knew she wanted to sue before she even got off the boat. When she was able to reach her husband, she told her husband and he contacted the attorneys.

Allison said Terry is thankful to be home with her husband, but is not feeling well and is going to a doctor.

"She's nauseated and actually has a fever," Allison said.

Terry is suing for breach of maritime contract, negligence, negligent misrepresentation and fraud as a result of the "unseaworthy, unsafe, unsanitary, and generally despicable conditions" on the crippled cruise ship.

"Plaintiff feared for her life and safety, under constant threat of contracting serious illness by the raw sewage filling the vessel, and suffering actual or some bodily injury," the lawsuit says.

Despite having their feet back on solid ground and making their way home, many passengers from the 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.

Sand-grain-sized drum extends reach of quantum theory

The banging of a tiny drum heralds the intrusion of the weird world of quantum mechanics into our everyday experience. Though no bigger than a grain of sand, the drum is the largest object ever to have been caught obeying the uncertainty principle, a central idea in quantum theory.

As well as extending the observed reach of quantum theory, the finding could complicate the hunt for elusive gravitational waves : it suggests that the infinitesimal motion caused by these still-hypothetical ripples in spacetime could be overwhelmed by quantum effects.

The uncertainty principle says that you cannot simultaneously determine both a particle's exact position and momentum. For example, bouncing a photon off an electron will tell you where it is, but it will also change the electron's motion, creating fresh uncertainty in its speed.

This idea limits our ability to measure the properties of very small objects, such as electrons and atoms. The principle should also apply to everyday, macroscopic objects, but this has not been tested – for larger objects, the principle's effects tend to be swamped by other uncertainties in measurement, due to random noise, say.

Quantum drum

To extend the known reach of the uncertainty principle, Tom Purdy and colleagues of the University of Colorado, Boulder, created a drum by tightly stretching a 40-nanometre-thick sheet of silicon nitride over a square frame with sides of half a millimetre – about the width of a grain of sand. They placed the drum inside a vacuum chamber cooled to a few degrees above absolute zero, minimising any interference by random noise.

By continuously firing a stream of photons at the drum they were able to get increasingly precise measurements of the position of the skin at any moment. However, this also caused the skin to vibrate at an unknown speed. When they attempted to determine its momentum, the error in their measurement had increased – just as the uncertainty principle predicts.

"You don't usually have to think about quantum mechanics for objects you can hold in your hand," says Purdy.

That the uncertainty principle holds sway at such a large scale could affect the hunt for gravitational waves, which are predicted by Einstein's theory of general relativity but have never been detected.

Mitigation strategy

Gravitational wave detectors look for very slight changes in the distance between two test masses caused by passing spacetime ripples. Purdy says his team's experiment confirms long-held suspicions that quantum uncertainty could overwhelm these very small changes.

Now he and others can use the drum to explore more advanced measurement techniques to mitigate the effects. For example, uncertainty in an object's momentum could lead to future uncertainty in its position and there should be ways to minimise such knock-on effects. "You can't avoid the uncertainty principle, but you can in some clever ways make it [such that] increasing the momentum doesn't add back to the uncertainty in position at a later time," says Purdy.

His experiment is a neat demonstration of the breakdown of the traditional notion that the atomic world is quantum while the macroscopic world is classic, says Gerard Milburn of the University of Queensland in Brisbane, Australia, who was not involved in the work. Previous, attempts to blur the quantum-classical divide have involved entangling diamonds and demonstrating quantum superposition in a strip of metal.

Despite these feats, Milburn doesn't rule out the prospect of a breakdown on really large scales. "Of course maybe one day we will see quantum mechanics fail at some scale. Testing it to destruction is a good motivation for going down this path," he says.

Smoking out tobacco: The rise of the e-cig

PARIS: The camera zooms in on a bearded man dragging on a cigarette and blowing out a thick cloud of smoke with what seems to be great satisfaction.

It resembles the TV smoking ads of yesteryear, now banned in most of the world, yet this modern-day offering is approved for American television viewers.

"You know what the most amazing thing about this cigarette is? It isn't one," explains a narrator as the modern-day Marlboro Man fixes the viewer with a broody stare before returning the reusable smoke to a container that resembles the traditional pocket-sized cardboard pack.

The NJOY "cigarette" is electronic -- its tip lights up with the help of an LED and what appears to be smoke is actually water vapour.

The actor is not smoking, but "vaping".

"Cigarettes, you have met your match," proclaims the ad for a product that claims to mimic "the look, feel and flavour of the real thing" -- minus the tar, ash, smoke and most toxins.

NJOY is one of a flurry of e-cigs entering the market as tobacco prices skyrocket and smokers become ever more concerned about the toxins they inhale.

But the jury is still out on whether the gadgets are safe or not.

"Without question, e-cigarettes are safer than traditional tobacco cigarettes," said Joel Nitzkin, of the American Association of Public Health Physicians.

"They deliver nicotine, with only the tiniest traces of other toxic chemicals."

But there are concerns that these battery-driven alternatives, officially called electronic nicotine delivery systems (ENDS), may pose health hazards we are not even aware of yet -- just like cigarettes before their ill-effects became clear.

"The safety of ENDS has not been scientifically demonstrated," the World Health Organisation said in response to a query.

"The potential risks they pose for the health of users remain undetermined."

The UN's health organ said some testing "suggests the presence of other toxic chemicals, aside from nicotine", and "strongly advised" consumers not to use them.

E-cigs first emerged in China in 2003 as an alternative to tobacco, which kills nearly six million people each year.

Just like their predecessors in the 1950s and 60s, electronic cigarettes are being advertised with attractive women and rugged, virile men -- hinting at a better, more popular you.

It's a strategy that seems to work.

A study in the American Journal of Preventive Medicine (AJPM) last month said 80 percent of users questioned in the United States, Britain, Canada and Australia believed e-cigarettes to be less harmful than their tobacco counterparts.

NJOY chief executive Craig Weiss told AFP that industry predictions are for electronic cigarette sales, which have doubled in the United States every year since 2008, to reach $1 billion (about 750,000 euros) in 2013.

"Growth in the category has occurred as a result of the millions of smokers who are actively seeking an alternative to cigarettes," he said by email.

The company would not comment on the health aspects.

According to Nitzkin, the hazard posed by traditional tobacco cigarettes is about 100 times higher than today's smokeless tobacco alternatives.

"When burned, cigarettes create a tarry residue that sticks to the inside of the smallest bronchial tubes of the lungs and in the alveoli, where the body absorbs the oxygen and releases the carbon dioxide.

"This tarry residue stays in place 24 hours a day, seven days a week for the life of the smoker," he said -- a side-effect that ENDS do not have.

Yet the European Respiratory Society said this month it could not classify e-cigs as a safe alternative to smoking, and stressed the principle that tobacco users "should not trade one carcinogenic product for another".

Last month, the UK's Advertising Standards Authority banned an ad for an e-cigarette, Nicolites, saying: "claims that the product was not harmful had not been substantiated".

Some researchers have also expressed concerns that non-smokers may get hooked on nicotine through e-cigarette use, or that the gadget would keep people addicted to nicotine who might otherwise have quit.

Nicotine can be harmful to children, pregnant women and adults with heart disease.

A recent study among 3,400 high school pupils in France showed that 12 percent of 15-to-16-year-olds who claimed never to have smoked before had experimented with ENDS, and 19 percent of 17-year-olds.

"As a doctor, I cannot recommend the electronic cigarette," lung specialist Bertrand Dautzenberg told AFP recently at the Pitie-Salpetriere hospital in Paris.

"But I would not interfere with a smoker who wants to take it up. With a cigarette, there is a 50 percent chance of killing oneself. With the electronic cigarette, we aren't too sure yet, but it is probably less," he said.

Mom of boy held in bunker is worried

STORY HIGHLIGHTS

• Phil McGraw speaks with mother of former Alabama child hostage


• She tells him she worried about trying to put him back on a school bus


• Ethan told her the Army killed the 'bad man'


• The 6-year-old tells his mom that 'My bus driver is dead'

(CNN) -- Jennifer Kirkland says she caught her 6-year-old son Ethan just staring at a school bus the other day.

He was mesmerized, his eyes locked on the yellow vehicle. He didn't say a thing, and she didn't know what to say to him.

The last time he was on a bus, he was sitting just behind the driver -- as he always did -- waiting for his stop so he could go home.

But the "bad man" got on, and killed the driver, his buddy Mr. Poland.

Appearing on the "Dr. Phil" show, Kirkland told Phil McGraw she was worried how her little boy was going to react the next time she tried to put him on the bus to school.

After being kidnapped, the recovery ahead

Photos: Alabama bunker standoff

HIDE CAPTION

Ethan has been having a hard time sleeping, she told the psychologist turned syndicated daytime talk show host.

He thrashes his arms, tosses and turns and sometimes he calls out.

It has only been almost 10 days since the FBI sent a rescue team into the bunker in Midland City, Alabama, where Ethan was held hostage for nearly a week by Jimmy Lee Dykes.

His mother hasn't asked Ethan what happened when he was there.

"I have not talked to Ethan about it," she said in an interview aired Wednesday. "I don't know how to. As a mother I want him to know that I'm there if he needs to talk. I don't know how to respond because I have never been through this."

Inside the bunker: From storm shelter to boy's prison

Ethan has seen two people shot to death. Dykes shot bus driver Charles Poland several times before he carried Ethan, who had fainted, off the bus and into an underground bunker Dykes had built on his property.

Then the FBI killed Dykes when negotiations broke down and authorities felt they had to rescue the boy before Dykes, who had a handgun, did something rash.

"The Army came in and shot the bad man," Kirkland said Ethan told her.

Kirkland said she had hoped Dykes wouldn't be harmed.

"From the very beginning, I had already forgiven Mr. Dykes even though he had my child," she said. "I could not be angry through this. My job was to be the mother."

She thinks Dykes had a soft spot for Ethan because he has disabilities. Dykes took care of her boy as best he could, she said.

He even fried chicken for the boy.

Still, as the crisis continued, she worried that Dykes might be spooked by something her child did -- or that he had enough supplies to stay down there for months. She worried her boy would think she had abandoned him.

She asked authorities to let her speak to Dykes.

"That's my baby. He's my world. He's my everything," she said. "Everything I do I do for him. And I was afraid I wasn't going to get him back."

When she did get him back, he was in the hospital, putting stickers on everyone in sight.

"Hey, bug, I sure have missed you," she recounted.

"I missed you, too," he answered.

FBI: Bombs found in Alabama kidnapper's bunker

Now she worries that even though he seems like the same playful little boy, there is an emotional storm ahead.

McGraw told her to talk to Ethan about his feelings, not what happened to him in the bunker.

"Let that decay in his young mind," he said.

McGraw asked Ethan a few questions, but as 6-year-olds are apt to do, he answered most with a "Yes" or a "No."

But when the doctor asked him how he got to school, Ethan said, "On my bus, but my ..."

Then he walked over to his mother and as if telling a secret, whispered in her ear, "But my bus driver is dead."

Kirkland told McGraw that it was Poland who helped Ethan conquer his fear of descending the steep school bus steps. Poland would cheer Ethan on and one day when the child hesitated and the mother went to help, the driver said, "Let him do it."

Since then, Ethan has had no problem.

But now his cheerleader won't be there, and Kirkland is anguished about her boy.

"Mr. Poland put him behind him so he could keep a good eye on him," she said.

Ethan hasn't been back to school yet. He's been busy opening birthday presents and playing with his favorite toys. On Wednesday, he made a new friend in Gov. Robert Bentley.

There's a picture from the event where little Ethan is sitting underneath the governor's desk. The child is beaming.

"Ethan is a loving, forgiving child," Kirkland said. "He is easy to go up to a perfect stranger and say, 'Can I have a hug?'"

That was the boy who went into that bunker. She is concerned it's not the child who came out.

Cruise passenger: People thought ship was "going to tip over"

(CBS News) Four thousand people who have been adrift at sea for four days are finally nearing shore Thursday night. This evening, the Carnival cruise ship named Triumph is being towed into Mobile Bay, Ala., and is expected to dock by midnight.

She left Galveston, Texas, a week ago, loaded with her maximum 3,143 passengers and crew of 1,100. The brochure described a four-day cruise in the Caribbean, but an engine room fire left her adrift and powerless.

All aboard have suffered in squalid conditions, stranded as Carnival slowly brought the ship in.

When CBS News flew over the Carnival Triumph, it was within sight of shore -- but still seven hours away from the dock.

Inside Carnival cruise nightmare: Passenger describes deteriorating conditions

From up there we could see people waving, some with signs that appear to be made out of bed sheets. One said "SOS" -- save our ship -- but at this point it's not the ship that needs saving, it's the passengers.

The ship has been without power since an engine room fire five days ago. CBS News reached passenger Jacob Combs on the phone.

"The really bad part is there was no running water and toilets for almost the first 30 hours," Combs said. "Once they finally did get running water, the toilets only worked in certain places. I would say it's the worst smell imaginable."

Emailed photos (above) reveal squalid conditions. Many passengers used red plastic bags as toilets. Hundreds slept in hallways or topside to escape the foul and stagnate air below deck.

Carnival CEO Jerry Cahill insists passengers were never at risk. But 22-year old Leslie Mayberry disagreed.

"It was leaning to one side it was literally like walking up hill whenever the boat was leaning," she said. "I mean it was very scary," Mayberry said. "I mean a lot of people thought it was going to tip over and sink. And then you look out on the deck and you see the ocean and there is no one, you are just by yourself and you are so alone, even though you are around 3,000 other people on this boat."

The towline pulling the 14-story tall ship snapped, delaying Thursday's operation. It was re-attached, but it will be nightfall before the ship arrives at the terminal. Nellie Betts came from Tupelo, Miss., to meet her daughter.

"There's no reason why those people should be out there as long as they have. Why? I want to understand why," she said. "What is taking them so long to get them out?"

Once the ship arrives at the terminal, Carnival plans to put most of those passengers on a two-hour bus rid to New Orleans or even to Galveston, Texas, but some already are saying, "no thanks" - they have relatives picking them up in Mobile so they can go straight home.

Disabled Cruise Ship Reaches Port in Mobile, Ala.

The ordeal of the disabled Carnival Triumph cruise ship carrying 4,000 passengers and crew appears to be almost over, with relatives waving at passengers on board as the ship reached port in Mobile, Ala.

After the ship arrived around 9:30 p.m. local time (10:30 p.m. ET), Carnival president and CEO Gerry Cahill thanked the ship's crew for coping with the situation and told reporters that he was headed on board to apologize directly to its passengers.

The Carnival Triumph departed Galveston, Texas, Thursday and lost power Sunday after a fire in the engine room disabled the vessel's propulsion system and knocked out most of its power.

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 the ship squabbling over scarce food.

"I know the conditions on board were very poor," Cahill said. "I know it was very difficult, and I want to apologize again for subjecting our guests for that. ... Clearly, we failed in this particular case."

Once the ship is secured, passengers were expected to be able to begin disembarking within 15 to 30 minutes, said Terry Thornton, Carnival's senior vice president of marketing.

It could take up to five more hours to get everybody off the huge ship.

"Inside the terminal, there's also warm food available," Thornton said. "There are blankets, there are cell phones and refreshments available for the guests that need that or want that assistance.

Passengers will have the options of boarding buses to Houston or Galveston, Texas, about seven hours away, or New Orleans, about two hours away, officials said.

"We have gotten our guests back to land," Cahill said. "Now, we need to get them home. ... The full resources of Carnival are working from here to get them home as quickly as we possibly can."

At an earlier news conference this afternoon, Thornton said that anyone with special needs and children will be the first to get off the boat. He said the company's number one priority is to make the process as "quick, efficient and comfortable" for guests as possible.

"There are some limitations. We know that up front," Thornton said. "The ship still does not have power. We only have one functioning elevator aboard."

Click here for photos of the stranded ship at sea.

The passengers were achingly close to port about noon today as the ship began to enter the channel and proceed to the cruise terminal. At 1 p.m., the lead tow boat had a tow gear break, so a spare tug boat that was on standby had to be sent in to replace it.

But once the second tug was in position and the lines were re-set, the towing resumed only briefly before the tow line snapped.

"We had to replace that tow line so the ship did not begin progressing back into the cruise terminal until 2 p.m.," Thornton said

Passengers desperate to get off the vessel 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 Friday 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."

Alabama State Port Authority Director Jimmy 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."

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 was assisting and there were multiple generators on board. Customs officials were to board the ship while it was being piloted to port to accelerate the embarkation, officials said.
