ATM Gene Linked To Increased Pancreatic Cancer Risk

A study in Cancer Discovery says mutations in the ATM gene may increase the hereditary risk for pancreatic cancer.

Pancreatic cancer is one of the most morbid cancers, with less than 5 percent of those diagnosed with the disease surviving to five years. Approximately 10 percent of patients come from families with multiple cases of pancreatic cancer.

Using next-generation sequencing, including whole genome and whole exome analyses, they identified ATM gene mutations in two kindreds with familial pancreatic cancer. When those initial findings were examined in a large series for patients, ATM mutations were present in four of 166 subjects with pancreatic cancer but were absent in 190 spousal control subsets.?

Knowledge of the presence of the ATM gene could lead to better screening for pancreatic cancer, the fourth most common cause of cancer-related death, but there are currently no recommended screening tests. Many doctors use endoscopy as a screening tool for pancreatic cancer, but researchers are still evaluating this technique in clinical trials.

"There was significant reason to believe this clustering was due to genetics, but we had not, to this point, been able to find the causative genes that explained the cluster of pancreatic cancer for a majority of these families," said lead author Alison Klein, Ph.D., associate professor of oncology at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins and director of the National Familial Pancreas Tumor Registry.

Bleakest outlook takes prize for forecasting

By Martin Wolk

For msnbc.com's panel of economic forecasters, the most pessimistic were the most accurate this year as the economy failed to meet even the relatively modest expectations of most experts.

David Rosenberg, the Canadian economist frequently known for his bearish views, takes the prize this year for the closest forecast among the 12 economists on our panel.

Gluskin Sheff

David Rosenberg says "retirement will become an increasingly elusive dream for many."

Rosenberg, chief economist for Gluskin Sheff & Associates, a wealth management firm, wins honors mainly because he correctly anticipated a year ago that 2011 would be a year of slow growth. Rosenberg projected U.S. economic growth of 2.3 percent for this year, compared with current projections that put GDP growth at just 1.7 percent for the year.

Rosenberg sees plenty of peril in the year ahead, especially with Europe in the midst of what he describes as a recession and China coming down from a heady period of rapid growth.

"2012 is probably going to be even more of a challenging year than 2011," he said.

While industrial companies have been driving the weak economic recovery for the past two years, they will be pressured this year by the strengthening dollar and the weakening of their primary markets in Asia and Europe, he said.

The expected expiration of Bush-era tax cuts at the end of 2012 also will cause anxiety and dampen consumer spending as Americans boost their personal savings in anticipation of lower take-home pay, he said.

While the labor market is "healing," most of the growth is in low-wage industries such as retail and hospitality, while high-paying industries such as?manufacturing and finance are laying off workers, Rosenberg said. As for housing, sales activity has picked up but prices are still declining, which has a negative impact on consumer confidence and perceptions of wealth.

Rosenberg just barely beat UCLA's Ed Leamer, another frequently bearish forecaster. Our methodology looked at how accurately forecasters predicted overall economic growth, consumer inflation, unemployment and short-term interest rates.

Most panelists, including Rosenberg, were overly pessimistic about the employment market, which has been weak but not?quite as bad as some had feared. Most economists predicted the unemployment rate would remain above 9 percent for the full year, but a sharp drop last month puts the current rate at 8.6 percent.

Most economists on our panel badly underestimated inflation, predicting consumer prices would rise less than 1 percent in 2011, compared with the actual 2.2 percent rate, excluding volatile food and energy prices.

Most economists predicted correctly that the Federal Reserve would leave interest rates at their current level of about zero percent, which the central bank has now virtually promised to leave in place through at least mid-2013.

With this ninth edition of our annual economic roundtable we are suspending the feature, although we continue to turn to our experts frequently for their regular analysis of the economy.

This year, for a change, we are turning to a different kind of expert and asking small business owners what they think about the prospects for the economy. We will be checking back with them often for their views on the economy.

Sea snails help scientists explore a possible way to enhance memory

ScienceDaily (Dec. 27, 2011) ? Efforts to help people with learning impairments are being aided by a species of sea snail known as Aplysia californica. The mollusk, which is used by researchers to study the brain, has much in common with other species including humans. Research involving the snail has contributed to the understanding of learning and memory.

At The University of Texas Health Science Center at Houston (UTHealth), neuroscientists used this animal model to test an innovative learning strategy designed to help improve the brain's memory and the results were encouraging. It could ultimately benefit people who have impairments resulting from aging, stroke, traumatic brain injury or congenital cognitive impairments.

The proof-of-principle study was published on the Nature Neuroscience website on Dec. 25. The next steps in the research may involve tests in other animal models and eventually humans.

The strategy was used to identify times when the brain was primed for learning, which in turn facilitated the scheduling of learning sessions during these peak periods. The result was a significant increase in memory.

"We found that memory could be enhanced appreciably," said John H. "Jack" Byrne, Ph.D., senior author and chair of the Department of Neurobiology and Anatomy at the UTHealth Medical School.

Building on earlier research that identified proteins linked to memory, the UTHealth investigators created a mathematical model that tells researchers when the timing of the activity of these proteins is aligned for the best learning experience.

Right now, the scheduling of learning sessions is based on trial and error and is somewhat arbitrary. If the model proves effective in follow-up studies, it could be used to identify those periods when learning potential is highest.

"When you give a training session, you are starting several different chemical reactions. If you give another session, you get additional effects. The idea is to get the sessions in sync," Byrne said. "We have developed a way to adjust the training sessions so they are tuned to the dynamics of the biochemical processes."

Two groups of snails received five learning sessions. One group received learning sessions at irregular intervals as predicted by a mathematical model. Another group received training sessions in regular 20-minute intervals.

Five days after the learning sessions were completed, a significant increase in memory was detected in the group that was trained with a schedule predicted by a computer. But, no increase was detected in the group with the regular 20-minute intervals.

The computer sorted through 10,000 different permutations in order to determine a schedule that would enhance memory.

To confirm their findings, researchers analyzed nerve cells in the brain of snails and found greater activity in the ones receiving the enhanced training schedule, said Byrne, the June and Virgil Waggoner Chair of Neurobiology and Anatomy at UTHealth.

"This study shows the feasibility of using computational methods to assist in the design of training schedules that enhance memory," Byrne said.

Other contributors from the UTHealth Department of Neurobiology and Anatomy include lead authors Yili Zhang, Ph.D., research fellow, and Rong-Yu Liu, Ph.D., senior research scientist, as well as George A. Heberton, medical student; Paul Smolen, Ph.D., assistant professor; Douglas A. Baxter, Ph.D., professor; and Len Cleary, Ph.D., professor.

The study, which is titled "Computational Design of Enhanced Learning Protocols," received support from the National Institutes of Health and the Keck Center National Library of Medicine Training Program in Biomedical Informatics of the Gulf Coast Consortia.

Deep-sea glow serves as bait

Marine bacteria light up to get a ride elsewhere

Web edition : 4:40 pm

Bioluminescent bacteria glow in the ocean for the same reason roadside eateries display neon signs: They want to attract hungry diners.

New laboratory experiments bolster the longstanding theory that marine bacteria light up to get themselves a free ride to other parts of the ocean in the digestive tracts of larger beasts, scientists from Israel and Germany report online December 27 in the Proceedings of the National Academy of Sciences.

?It?s terrific to see this experiment,? says J. Woodland Hastings, a bioluminescence expert at Harvard University who was not involved in the research. ?It?s nice to see these ideas confirmed.?

Many deep-sea creatures, from bacteria to fish to squid, are bioluminescent ? meaning they generate light inside their bodies through chemical reactions. Different organisms glow for different reasons; the anglerfish, for instance, can light up a lure to attract prey, while some plankton glow to signal possible danger when a boat or swimmer passes nearby.

Bioluminescent bacteria live throughout the ocean, and may have several reasons to explain their built-in glow. More than three decades ago, researchers suggested that one such reason could be to mark the presence of a floating food particle, so that a passing fish would see it and eat it. But no one had tracked this idea all the way to its logical conclusion ? until now.

Margarita Zarubin, a graduate student at the Interuniversity Institute for Marine Sciences in Eilat, Israel, started with a type of luminescent bacteria, Photobacterium leiognathi, found 600 meters deep in the Red Sea. She put one bag of glowing bacteria at one end of a seawater tank, and at the other end she put another bag of bacteria that had a genetic change that kept the microbes dark. Shrimp and other small animals clustered around only the glowing bacteria.

Next she let brine shrimp swim in water with the luminescent bacteria. After two and a half hours, the shrimp themselves began to glow from their microbial dinner. ?We could see the luminescence from inside their guts,? says Zarubin, who did the work while at the University of Oldenburg in Germany and is now with the Hebrew University of Jerusalem.

Then she dropped both glowing and dark shrimp into a flume so they were swept past a hungry cardinalfish; the fish ate only the luminescent shrimp. Finally, the scientists tested the fish feces, and found that the bacteria had passed unscathed through the fish guts and came out intact. The whole process spreads the bacteria through the water faster than they could move otherwise, Zarubin says.?

For their part, the shrimp must balance the benefit of eating a food particle that happens to glow against the drawback of becoming luminescent themselves, thus making themselves more vulnerable to predators. But in deep dark waters where food is scarce, the advantage of getting a snack probably outweighs the disadvantage of potentially being eaten, Zarubin says.

Some animals have pigment in their guts that can block light emission as they digest glowing particles, says Michael Latz, a marine biologist at the Scripps Institution of Oceanography in La Jolla, Calif. Only when the animal pops out a glowing fecal pellet do the bacteria become visible again, signaling another creature to eat them and keep the microbes on the move.

Such deep-sea bacterial recycling could be important for more than just understanding bioluminescence, Latz says. The guts of shrimp and other small marine creatures may serve as a highway for spreading bacterial pathogens throughout the sea, like the one that causes cholera.

IBM and University of Guadalajara create Smarter Cities Exploration Center; transportation pilot seeks to reduce commuting time in city by 15%

IBM and University of Guadalajara create Smarter Cities Exploration Center; transportation pilot seeks to reduce commuting time in city by 15%

IBM and the University of Guadalajara (UdeG) in Mexico have created a Smarter Cities Exploration Center. Supported by technical and intellectual guidance of IBM?s global research lab experts, the Center will be the first of its kind in Latin America, tasked with the mission to design solutions to tackle infrastructure challenges faced by Guadalajara?Mexico?s second-largest city?and other cities around the world.

Joint work between IBM and the University of Guadalajara will focus on research aimed at identifying ways to apply advances in technology to the high degrees of instrumentation and massive data volumes that comprise the core systems of a city such as transportation, healthcare, education, public safety, energy and water.

The center has already started the development of a transportation pilot that could reduce commuting time in the city by 15%, representing approximately US$ 90 million in savings per year by enabling citizens to use their time more productively and decrease carbon emissions.

This pilot?the first in a series of initiatives?will provide real-time analysis and forecasting of traffic behavior for 1.7 million vehicles in Guadalajara, enabled by supercomputing technology, analytics and web services connected to mobile devices feeding updates to users. The objective is to increase the efficiency of commuting alternatives, including a 17-km-long (or approximately 10 miles) north-to-south corridor that currently takes more than an hour to complete.

IBM and the University will share knowledge through the exchange of intellectual property among researchers, and the use of IBM?s data analytics, supercomputing and cloud computing capabilities to drive the development of new pilots and solutions.

The University will foster the assimilation of high-level competencies and expertise by its doctoral students and researchers, to support efforts designed to tackle issues that have a high social and economic impact for Latin America.

Intelligent Operations Center for Smarter Cities. Earlier this year, IBM introduced the Intelligent Operations Center for Smarter Cities, a new solution designed to help cities of all sizes gain a holistic view of information across city departments and agencies. By infusing analytical insights into municipal operations through one central point of command, cities are to be able to better anticipate problems, respond to crises, and manage resources.

IDC Government Insights estimates the new Smarter Cities information technology market opportunity at $34 billion in 2011, increasing more than 18% per year to $57 billion by 2014.

All cities are made up of a complex system of systems that are all inextricably linked. The Intelligent Operations Center for Smarter Cities recognizes the behavior of the city as a whole, thus providing more coordinated and timely decision-making based on deep insights into how each city system will react to a given situation. With more than 2,000 smarter cities engagements worldwide, we are now applying best practices and solutions that can be scaled to cities of all sizes around the globe.

?Anne Altman, general manager, Global Public Sector, IBM

As the majority of the world?s population moves to metropolitan areas, key city systems such as water, power and transportation are being severely strained. For citizens, a smarter city can mean automatically finding the fastest way to get to work, electricity and drinking water that can be counted on, and safer streets, to start.

The Intelligent Operations Center combines patented analytics technologies, created by IBM Research in collaboration with cities around the world, as well as leading edge technologies acquired in recent acquisitions. It is also designed to run on IBM workload-optimized systems.

SmarterCities Forum. In November, IBM hosted the SmarterCities Forum in Rio de Janeiro?an event that brought together 550 leaders of business, academia and government from various cities across Latin America and the globe to discuss models to make cities smarter.

To address issues that are common to the entire region, the SmarterCities Rio forum brought forth best practices and pragmatic suggestions for making city systems smarter in critical areas such as security, transportation, energy and construction, among others.

(AP) ? The FBI joined the search for a missing 9-year-old Indiana girl with physical and emotional problems Monday as agents descended on the mobile home park where she lived and that's a known haven for registered sex offenders.

About a half-dozen people in black windbreakers, several of whom identified themselves as FBI agents, were at the mobile home park Monday where Aliahna Lemmon went missing from a family friend's home on Friday. Some with search dogs were seen at a nearby storage facility.

Monday's renewed search came a day after local police declined to search Sunday. Allen County sheriff's department officials also originally had not planned to search Monday either, unless new leads arose through tips from the public or interviews, Cpl. Jeremy Tinkel, a department spokesman, said earlier in the day.

Local police haven't said what they think happened to Aliahna.

Meanwhile, agents at the scene Monday wouldn't say why the FBI was involved. An agency spokesman didn't immediately return phone calls and e-mails seeking comment.

More than 100 emergency workers conducted an extensive search Saturday for Aliahna around the rundown mobile home park on Fort Wayne's north side where she was last seen. No active search was done Sunday for the girl.

According to a state website, 15 registered sex offenders live at the mobile home park that numbers about two dozen homes.

Elizabeth Watkins, 52, who has lived at the park for six months with her 4-year-old granddaughter, said it's well-known that several sex offenders live in the neighborhood.

"It's scary," she said. "I don't know how a parent could leave their child alone."

Aliahna's mother, Tarah Souders, 28, told The Journal Gazette her daughter has vision and hearing problems and suffers from attention deficit disorder and emotional problems. She also has a history of sleepwalking, family members said.

Aliahna and her sisters were staying at a family friend's nearby home because their mother had been sick with the flu and Aliahna's stepfather works at night and sleeps during the day, The Journal Gazette reported Monday.

Mike Plumadore, 39, told the newspaper Sunday that he left the three girls in his mobile home about 6 a.m. Friday and went to a gas station about a mile away to buy a cigar. Authorities have said the store's surveillance video shows him there about that time.

"I had deadbolted the door," he said. "When I got back, all the girls was here."

He said he smoked his cigar and went back to sleep, then woke up about 10 a.m. when Aliahna's mother called. After that call, he realized the door to the home was unlocked and that Aliahna was gone. He said Aliahna's sisters, both 6 years old, told him that Aliahna had left with her mom.

Plumadore said it wasn't until he talked with Aliahna's mom about 8:30 p.m. that they realized she was missing and police were notified.

Plumadore is not listed on the state's website that lists registered sex offenders.

Tarah Souders said miscommunication between the two of them caused the delay in determining that Aliahna had vanished.

"She's never wandered off," Souders said. "She's never done anything like this before."

But Aliahna does have a history of sleepwalking, even unlocking doors and going outside while sleeping, said her grandmother, Amber Story.

"I just hope that she's not suffering or in pain," Story said.

Souders said her daughter also has vision and hearing problems and suffers from attention deficit disorder and emotional problems.

Republicans attempting to remove President Obama from Georgia ballot

This is disgraceful.

Five separate lawsuits have been filed to PREVENT President Obama from being on the 2012 ballot. While their arguments are foolish, it still requires a vigorous defense in the Georgia judicial system. If successful, Georgia would be the ONLY state to *not* have the President on the November ballot.

Democrats can?t allow our state to be America?s laughing stock. We have to fight these lawsuits, two of which are being represented by a sitting state legislator in the State Capitol.

Merry Christmas from the GA GOP.

(AP) ? A 9-year-old girl flying by herself to visit her grandmother had to change planes unexpectedly, sending her relatives into a panic when her original Southwest Airlines flight landed without her.

Chloe Boyce took off from Tennessee on Tuesday, bound for LaGuardia Airport in New York. Bad weather forced her plane to detour, and the passengers had to change planes. When the plane she was initially on arrived at LaGuardia, family members said it took close to an hour to locate her.

"When I got the text (from her mother) that she wasn't on the plane, and Southwest doesn't know where she is, I started freaking out," said Joseph Kerr, the girl's stepfather.

Southwest spokesman Brad Hawkins said the airline apologized to the family for not letting them know she had changed planes.

Chloe, of Clarksville, Tenn., was accompanied by Southwest employees during her trip, but she said she was a little nervous because nobody told her why she had to get off the plane in Baltimore.

"I was like 'I'm supposed to be getting off at LaGuardia. I'm not supposed to get off this plane,'" she said.

Chloe's journey started in Nashville. She was rerouted to Cleveland, then went to Columbus, Ohio, before landing in Baltimore. From there, she made it to New York, 3 ? hours later than scheduled. After meeting with her relatives, they drove to her grandmother's house in Danbury, Conn.

Her stepfather is an Army sergeant based at Fort Campbell, Ky., so she is used to traveling, her family said.

"She was definitely more calm than we were," said Elena Kerr, her mother, who reached Chloe by cell phone at the Baltimore airport when she did not show up on time in New York.

Southwest gave the family a $250 flight voucher and refunded the girl's ticket, but Chloe's family has not received an explanation for why the airline did not tell them about the changes. He said they plan to ask the Federal Aviation Administration to require airlines to notify guardians of any changes to flights carrying unaccompanied minors.

Hawkins, the Southwest spokesman, said the airline tries to notify parents of "irregular operations," even though it is not mandatory. He also said the airline tries to avoid such situations by booking unaccompanied minors on itineraries that don't require changing planes.

For the return trip, Joseph Kerr said they will be driving back.

"That way we know where she is, who she is with, and she is safe," he said.

Kindle Fire 6.2.1 update launches, brings Silk browser improvements (Digital Trends)

Mentioned two weeks ago by Amazon officials, the Internet company has started rolling out version 6.2.1 of the Kindle Fire software. Much of the user interface has been tweaked to become more responsive to screen tapping and navigation of content is much more fluid. The Silk browser is also smoother when moving through different Web pages and loading content. The update brings?customization to the tablet allowing users to hide items that appear on the?carousel as well as the ability to password protect?Wi-Fi access. By using a password on the device, tablet owners can prevent other users from purchasing content while browsing movies, books or other media.?To update your Kindle manually, connect to a Wi-Fi network and tap the Quick Settings icon in the upper right corner to find the ?Sync? option.?

Amazon-Kindle-FireThis update also?removes root privileges on tablets that have been rooted to replace the?operating system with custom firmware?as pointed out by Engadget. If a user is still using any Amazon software on a rooted tablet, they are?susceptible?to automatic updates when the device connects to any Wi-Fi network. Replacing the stock Amazon software with most forms of alternate software may void the warranty of the tablet and users are also likely to lose access to Amazon apps such as?Amazon Instant Video and the Lending Library feature. However, many developers creating software for rooted versions of the tablet have found the Kindle Fire relatively friendly when it comes to application development.?

According to a recent press release from Amazon, the Kindle Fire has been flying off the shelves and the company has sold about one million tablets per week during December. Amazon has also extended an offer of free two-day shipping on all Kindle models until?8 p.m. Pacific time on Dec. 21. This will allow any Kindle to arrive by December 23 and procrastinating Christmas shoppers will have enough time to receive the Kindle model on Friday to wrap it before the holiday on Sunday.?

Gaming's Best And Worst Star Wars Characters - Features - www ...

The cast of the Star Wars universe isn?t perfect. For every cool character like Darth Vader, fans have to endure a lame one like Jar Jar Binks, and that rule holds true for Star Wars games as well as the movies. Fortunately, games have given rise to some of the most memorable characters in the galaxy far, far away?even though it means putting up with some stinkers, too. In this feature, we examine gaming?s five most significant and five most shameful additions to the Star Wars fiction.

?By Joe Juba, Adam Biessener, Kyle Hilliard, Matt Miller, Ben Reeves, and Tim Turi

AWESOME: HK-47 (Knights of the Old Republic)

As an assassin droid, HK (which stands for ?Hunter-Killer,? by the way) isn?t just another robot built to make humans? lives easier. He has a hostile attitude toward all organic life, and gleefully describes the various killing methods he has employed (or would like to employ). HK takes great pride in his assassination skills, regularly refers to humans as ?meatbags,? and is generally just hilarious to interact with. A psychopathic robot may not seem like great company, but HK-47 is easily the best companion the KOTOR series has to offer.

LAME: Dash Rendar (Shadows of the Empire)

If you thought Link or Gordon Freeman epitomized the silent video game protagonist, then you haven?t met Dash Rendar. In fact, nobody has met Dash Rendar. He is an empty shell of a character with weird shoulder pads who wants so badly to be Han Solo that he even has a ship that looks like a miniature Millennium Falcon. It?s a wonder Lucas didn?t just call him San Holo. Here?s the good news: He dies in the end of Shadows of The Empire, and Luke and Leia barely feel the need to mourn. Spoiler alert, by the way, even though no one really cares.

AWESOME: Kyle Katarn (Dark Forces)

This Imperial defector?s colorful history makes him an ideal Star Wars hero. Originally a Stormtroomer, Katarn shed his white armor in favor of becoming a mercenary employed by the Rebellion. While in the Rebels? service, he not only single-handedly blasted his way through an Imperial base to secure Death Star plans, he also destroyed every trace of the empire?s diabolical Dark Trooper super-soldier program. As if these feats didn?t make him heroic enough, he also picked up a lightsaber, traveled to the Valley of the Jedi, and trained himself to become one of the best force-wielders in Star Wars history.

LAME: Juno Eclipse (The Force Unleashed)

A love story is a key part of both Star Wars film trilogies. In an effort to make The Force Unleashed feel like a real part of the mythology, the team at LucasArts threw together Juno Eclipse as romantic interest for Starkiller. However, her only defining characteristic is the fact that she speaks with a British accent ? players are given no clue as to why she is likable or how she and Starkiller develop a rapport. The relationship between Juno and Starkiller is even more poorly developed than the one between Anakin and Padme in Episode II, which we wouldn?t have thought was possible.

Suu Kyi's party registers to run in Myanmar polls (AP)

NAYPYITAW, Myanmar ? Opposition leader Aung San Suu Kyi formally registered her party Friday for any upcoming elections, returning the Nobel laureate to the political arena.

Suu Kyi decided last month to formally rejoin politics in the military-dominated country after recent reforms by the nominally civilian administration that took power this year. Suu Kyi, National League for Democracy leader Tin Oo and other party members registered the party at the Union Election Commission in the capital, Naypyitaw.

The party boycotted last year's general elections because of restrictive rules that among other things prevented Suu Kyi from being a candidate. The government has since lifted many of those restrictions.

The government had disqualified the NLD for boycotting the election.

NLD spokesman Nyan Win said the party will contest all vacant seats in an upcoming by-election and Suu Kyi will soon announce in which constituency she will run.

No date has been set for that election, but last week Election Commission Chairman Tin Aye said the government will announce it three months before the by-election, giving candidates time to campaign.

Allowing Suu Kyi's party back into the political fold will likely give the government greater legitimacy at home and abroad. It has already won cautious praise from international observers and critics including the United States, for introducing reforms.

During her visit to Myanmar early this month U.S. Secretary of State Hillary Rodham Clinton said she wants to ensure that future elections are "free, fair and credible in the eyes of the people."

The polls in November 2010 were Myanmar's first since the NLD overwhelmingly won a general election in 1990. The military junta at that time refused to honor the results.

The regime kept Suu Kyi under house arrest during different periods for a total of 15 years. She was released just after last year's elections and is now free to move about and meet people.

The government continues to hold hundreds of other political prisoners and Suu Kyi has said the NLD will continue to work for their release.

How diving marine mammals manage decompression

ScienceDaily (Dec. 21, 2011) ? Any diver returning from ocean depths knows about the hazard of decompression sickness (DCS) or "the bends." As the diver ascends and the ocean pressure decreases, gases that were absorbed by the body during the dive, come out of solution and, if the ascent is too rapid, can cause bubbles to form in the body. DCS causes many symptoms, and its effects may vary from joint pain and rashes to paralysis and death.

But how do marine mammals, whose very survival depends on regular diving, manage to avoid DCS? Do they, indeed, avoid it?

In April 2010, the Woods Hole Oceanographic Institution's Marine Mammal Center (MMC) invited the world's experts in human diving and marine-mammal diving physiology to convene for a three-day workshop to discuss the issue of how marine mammals manage gas under pressure. Twenty-eight researchers discussed and debated the current state of knowledge on diving marine mammal gas kinetics -- the rates of the change in the concentration of gases in their bodies.

The workshop resulted in a paper, "Deadly diving? Physiological and behavioural management of decompression stress in diving mammals," which was published Dec. 21, 2011, online in the Proceedings of the Royal Society B.

"Until recently the dogma was that marine mammals have anatomical and physiological and behavioral adaptations to make the bends not a problem," said MMC Director Michael Moore. "There is no evidence that marine mammals get the bends routinely, but a look at the most recent studies suggest that they are actively avoiding rather than simply not having issues with decompression."

Researchers began to question the conventional wisdom after examining beaked whales that had stranded on the Canary Islands in 2002. A necropsy of those animals turned up evidence of damage from gas bubbles. The animals had stranded after exposure to sonar from nearby naval exercises. This led scientists to think that diving marine mammals might deal with the presence of nitrogen bubbles more frequently than previously thought, and that the animals' response strategies might involve physiological trade-offs depending on situational variables. In other words, the animals likely manage their nitrogen load and probably have greater variation in their blood nitrogen levels than previously believed.

Because the animals spend so much time below the ocean's surface, understanding the behavior of diving marine mammals is quite challenging. The use of innovative technology is helping to advance the science. At WHOI, scientists have used a CT scanner to examine marine mammal cadavers at different pressures to better understand the behavior of gases in the lungs and "get some idea at what depth the anatomy is shut off from further pressure-kinetics issues," Moore said. For other studies, Moore and his colleagues were able to acquire a portable veterinary ultrasound unit to look at the presence or absence of gas in live, stranded dolphins.

There's still a lot to be learned, including whether live animals have circulating bubbles in their systems that they are managing. If they do, says Moore, noise impacts and other stressors that push the animal from a normal management situation to an abnormal situation become more of a concern. "When a human diver has some bubble issues, what will they do? They will either climb into a recompression chamber so that they can recompress and then come back more slowly, or they'll just grab another tank and go back down for a while and . . . and just let things sort themselves out. What does a dolphin do normally when it's surfaced? The next things to do is to dive, and the one place you can't do that is in shallow water or most particularly if you are beached."

APNewsBreak: US aid a step toward Korea nuke talks (AP)

The United States is poised to announce a significant donation of food aid to North Korea this week, the first concrete accomplishment after months of behind-the-scenes diplomatic contacts between the two wartime enemies. An agreement by North Korea to suspend its controversial uranium enrichment program will likely follow within days.

A broad outline of the emerging agreement has been made known to The Associated Press by people close to the negotiations.

Discussions have been taking place since summer in New York, Geneva and Beijing. They have already yielded agreements by North Korea to suspend nuclear and ballistic missile testing, readmit international nuclear inspectors expelled in 2009, and resume a dialogue between North Korea and South Korea, according to the people, who spoke on condition of anonymity because of sensitivity of the negotiations.

The announcement of the food aid, expected to take place as early as Monday in Washington, not only would be welcome news for North Korea, but also pave the way for another crucial U.S.-North Korea meeting in Beijing on Thursday. That meeting in turn could lead within weeks to the resumption of nuclear disarmament talks that would also include China, Japan, Russia and South Korea.

The so-called six-party talks were last held three years ago, and resuming them would amount to a foreign policy coup for the Obama administration.

Suspension of uranium enrichment by North Korea had been a key demand from both the U.S. and South Korea of the North, which has tested two atomic devices in the past five years.

The U.S. would provide 240,000 tons of high-protein biscuits and vitamins ? 20,000 tons a month for a year ? but not much-wanted rice, according to reports in the South Korean media. It would be the first food aid from the U.S. in nearly three years.

Negotiators have sought for two decades to convince North Korea to dismantle its plutonium-producing nuclear reactor at Yongbyon, which the government insists exists to generate much-needed power. But plutonium can be used to make atomic bombs, and North Korea also stands by its right to develop missiles to defend itself against the nuclear-armed United States.

In 2009, North Korea tested a missile capable of reaching U.S. shores, earning widespread condemnation and strengthened U.N. sanctions. An incensed North Korea, which insisted the rocket launch was designed to send a satellite into space, walked away from ongoing nuclear disarmament talks in protest.

In the weeks that followed, North Korea tested a nuclear device and announced it would begin enriching uranium, which would give it a second way to make atomic weapons.

"North Korea's disclosure of a uranium enrichment program was bait" for negotiations and aid, said Jeung Young-tae, an analyst with the Korea Institute for National Unification in Seoul. "And the United States grabbed that bait."

With little arable land and outdated agricultural practices, North Korea has long struggled to feed its people. Flooding and a harsh winter further destroyed crops. The World Food Program issued a plea earlier this year for $218 million in humanitarian help to feed the most vulnerable.

As donations trickled in, Washington deliberated for months on whether to contribute food aid.

Then, in July, U.S. and North Korean negotiators met in New York, and again in Geneva in November. Two days of discussion on food aid last week in Beijing led up to this week's expected announcement of a food-aid package.

This diplomatic dance has unfolded as North Korea prepares for two milestone events for its citizens: the 100th anniversary of the April 1912 birth of President Kim Il Sung, who is officially regarded as the nation's "eternal president" long after his death, and a movement to prepare Kim Jong Un, son of current leader Kim Jong Il, to become the next ruler.

A peace treaty with the U.S. to formally end the Korean War and ensure stability on the Korean peninsula has remained a key goal for the North Korean leadership. The war that erupted in 1950 was suspended with an armistice in 1953, but tensions on the Korean peninsula have remained high ever since.

A technical state of war remains, and the U.S. maintains a garrison of 28,500 troops in South Korea to protect its ally against aggression.

More recently, the deadly March 2010 sinking of a South Korean warship and a November 2010 artillery attack on a front-line South Korean island populated by civilians only deepened tensions between North Korea and the West.

Besides a food aid deal, another tangible sign of diplomatic progress has been North Korea's recent willingness to discuss letting U.S. military officials into North Korea to recover remains of U.S. servicemen killed ? a project suspended by Washington in 2005. North Korea has agreed to allow a first U.S. team into the country in the spring, officials said.

But overlying all of this is a desire by the U.S. and its allies to restart nuclear disarmament negotiations.

In Washington, State Department spokeswoman Victoria Nuland said Friday that there was no announcement yet on food aid or further U.S. talks with North Korea.

However, those with knowledge of the negotiations told the AP an announcement was expected as soon as Monday, and would include a provision for better monitoring of food distribution to allay concerns that aid meant for the most needy is diverted to North Korea's powerful military.

Nuland, who has said the government wants to ensure the food goes to the needy, "not to the regime, and not to go locked up in storehouses," has said the food in question is better characterized as "nutritional assistance."

"When you think about food, you think about sacks of rice, cans of food, things that might easily be diverted to the wrong purpose," she said Thursday.

"When you talk about nutritional assistance, it could be that, but it could also be things like vitamin supplements to populations in need, like women and children; it could be high protein biscuits or other things." The concern, she said, is that items intended for starving women and children "not find themselves on some leader's banquet table."
