Chimps: Ability to 'think about thinking' not limited to humans

Apr. 3, 2013 ? Humans' closest animal relatives, chimpanzees, have the ability to "think about thinking" -- what is called "metacognition," according to new research by scientists at Georgia State University and the University at Buffalo.

Michael J. Beran and Bonnie M. Perdue of the Georgia State Language Research Center (LRC) and J. David Smith of the University at Buffalo conducted the research, published in the journal Psychological Science of the Association for Psychological Science.

"The demonstration of metacognition in nonhuman primates has important implications regarding the emergence of self-reflective mind during humans' cognitive evolution," the research team noted.

Metacognition is the ability to recognize one's own cognitive states. For example, a game show contestant must make the decision to "phone a friend" or risk it all, dependent on how confident he or she is in knowing the answer.

"There has been an intense debate in the scientific literature in recent years over whether metacognition is unique to humans," Beran said.

Chimpanzees at Georgia State's LRC have been trained to use a language-like system of symbols to name things, giving researchers a unique way to query animals about their states of knowing or not knowing.

In the experiment, researchers tested the chimpanzees on a task that required them to use symbols to name what food was hidden in a location. If a piece of banana was hidden, the chimpanzees would report that fact and gain the food by touching the symbol for banana on their symbol keyboards.

But then, the researchers provided chimpanzees either with complete or incomplete information about the identity of the food rewards.

In some cases, the chimpanzees had already seen what item was available in the hidden location and could immediately name it by touching the correct symbol without going to look at the item in the hidden location to see what it was.

In other cases, the chimpanzees could not know what food item was in the hidden location, because either they had not seen any food yet on that trial, or because even if they had seen a food item, it may not have been the one moved to the hidden location.

In those cases, they should have first gone to look in the hidden location before trying to name any food.

In the end, chimpanzees named items immediately and directly when they knew what was there, but they sought out more information before naming when they did not already know.

The research team said, "This pattern of behavior reflects a controlled information-seeking capacity that serves to support intelligent responding, and it strongly suggests that our closest living relative has metacognitive abilities closely related to those of humans."

The research was supported in part by the National Institutes of Health and the National Science Foundation.

White House tries its hand at April Fools' joke

WASHINGTON (AP) ? The White House, busy with its annual Easter Egg Roll, also managed to pull off an April Fools' prank.

The White House Twitter account announced earlier Monday to be on the lookout for a "special video message from the president."

Instead, viewers got a surprise visitor to the press briefing room.

The piece began with a shot of the familiar lectern regularly used by press secretary Jay Carney. It was empty as the presidential entrance march played. Then a small head peeked over the edge of the stand.

"It looks like you were expecting somebody else."

Indeed. It was Robby Novak, who plays "Kid President" in a series of popular YouTube videos. "April Fools' on all of you all," he said.

Dissident Cuban blogger gets warm reception from Miami exiles

By David Adams

MIAMI (Reuters) - Cuba's best-known dissident, independent journalist and blogger Yoani Sanchez, received a hero's welcome on Monday from the Cuban-American exile community in Miami, her latest stop in an 80-day tour of more than a dozen countries.

In was the largest and most politically unified reception in at least a decade for a dissident from the island by Miami's Cuban-American exile community, which has often clashed with opposition figures in Cuba over political tactics and goals.

With many leaders of Miami's Cuban-exile community in attendance, Sanchez was introduced as "an authentic defender and heroine" of human rights in Cuba by Eduardo Padron, the president of Miami Dade College, which hosted the event.

She was greeted by about 1,000 invitees with a standing ovation accompanied by shouts of "Freedom! Freedom!" as she took the stage at Miami's iconic Freedom Tower, a one-time processing center in the 1960s for Cuban refugees.

Seemingly surprised by the warmth and size of the reception, she smiled and flashed the V for victory sign in response, before receiving the keys to the city of Miami.

Sanchez, a slender 37-year-old Havana resident with striking waist-length hair, has incurred the wrath of Cuba's government for constantly criticizing its communist system in her "Generation Y" blog and using Twitter to denounce repression.

The blog has won several top international journalism prizes and is translated into 20 languages, while her Twitter account has nearly 500,000 followers. Few of these though are in Cuba, where the government severely restricts the Internet.

In a prepared speech, Sanchez described in often poignant terms her empathy with the pain felt by many Cuban exiles who have left the island over the last half century following the 1959 revolution that swept Fidel Castro to power.

Sanchez blamed the Castro government for dividing the country and called for unity between exiles and Cubans still living on the island.

"That's why I am here today with you so that nobody again can divide us," she said to roars of approval. "Without you (exiles) our country would be incomplete, like someone missing an amputated limb," she added.

CUBA'S BERLIN WALL

Sanchez compared Cuba to Germany before the Berlin Wall was brought down in 1990. Unlike the Berlin wall, Cuba's was "not made of concrete but of lies," she said, to another standing ovation.

Sanchez defended her highly publicized criticism of the longstanding U.S. economic embargo against Cuba, saying it provided the Cuban government with a convenient excuse for tough living conditions on the island under communist rule.

"There are much more important things (than the embargo)," she said. "The (Cuban) government has exaggerated its importance," she added, saying different opinions about the embargo among opponents of the Cuban government were not a reason for division.

Unlike other dissidents, who have been received with suspicion in Miami, Sanchez appears to have won the exile community over with her charm and wit, as well as her straight-talking blog.

"No one has been more effective in denouncing what's going on in Cuba and the myths of the Cuban regime," said Carlos Alberto Montaner, a prominent Cuban exile politician and journalist.

"I don't know of any dissident from the island who has been this warmly received," said Felice Gorordo, co-founder of Roots of Hope, a group of young, Cuban American professionals and university students. "She has the ability to speak to the pain of the exiles and to the daily struggles of life in Cuba."

REFORM IN CUBA

Sanchez's case is viewed as a test of the Cuban government's commitment to free travel under reforms announced late last year that require only a passport, renewed every two years, to leave the country.

It is the first time Cuban authorities have allowed Sanchez to leave the island since 2004, when she returned from a two-year stay in Switzerland and began launching a string of digital publications.

Cuba's leaders consider dissidents traitorous mercenaries in the employ of the United States and other enemies. Official bloggers regularly charge that Sanchez's international renown has been stage-managed by Western intelligence services.

Asked on Monday how she has been able to finance her trip crisscrossing the Atlantic several times between the United States, Europe and Latin America, Sanchez praised the generosity of friends and universities that have invited her to speak.

"The Cuban government says I am a millionaire. It's true. I have millions of friends," she said.

Sanchez is in Miami this week for a string of public appearances at local universities and a family reunion with her sister, a pharmacist, and brother-in-law, as well as her niece, whom she has not seen since they left Cuba two years ago.

She arrived in Miami after stops in Washington and New York that followed visits to Brazil and Mexico. She leaves for Peru on Thursday before returning to Europe, including stops in Germany.

Mexican drug cartel agents infiltrate U.S.

CHICAGO (AP) ? Mexican drug cartels whose operatives once rarely ventured beyond the U.S. border are dispatching some of their most trusted agents to live and work deep inside the United States ? an emboldened presence that experts believe is meant to tighten their grip on the world's most lucrative narcotics market and maximize profits.

If left unchecked, authorities say, the cartels' move into the American interior could render the syndicates harder than ever to dislodge and pave the way for them to expand into other criminal enterprises such as prostitution, kidnapping-and-extortion rackets and money laundering.

Cartel activity in the U.S. is certainly not new. Starting in the 1990s, the ruthless syndicates became the nation's No. 1 supplier of illegal drugs, using unaffiliated middlemen to smuggle cocaine, marijuana and heroin beyond the border or even to grow pot here.

But a wide-ranging Associated Press review of federal court cases and government drug-enforcement data, plus interviews with many top law enforcement officials, indicate the groups have begun deploying agents from their inner circles to the U.S. Cartel operatives are suspected of running drug-distribution networks in at least nine non-border states, often in middle-class suburbs in the Midwest, South and Northeast.

"It's probably the most serious threat the United States has faced from organized crime," said Jack Riley, head of the Drug Enforcement Administration's Chicago office.

The cartel threat looms so large that one of Mexico's most notorious drug kingpins ? a man who has never set foot in Chicago ? was recently named the city's Public Enemy No. 1, the same notorious label once assigned to Al Capone.

The Chicago Crime Commission, a non-government agency that tracks crime trends in the region, said it considers Joaquin "El Chapo" Guzman even more menacing than Capone because Guzman leads the deadly Sinaloa cartel, which supplies most of the narcotics sold in Chicago and in many cities across the U.S.

Years ago, Mexico faced the same problem ? of then-nascent cartels expanding their power ? "and didn't nip the problem in the bud," said Jack Killorin, head of an anti-trafficking program in Atlanta for the Office of National Drug Control Policy. "And see where they are now."

Riley sounds a similar alarm: "People think, 'The border's 1,700 miles away. This isn't our problem.' Well, it is. These days, we operate as if Chicago is on the border."

Border states from Texas to California have long grappled with a cartel presence. But cases involving cartel members have now emerged in the suburbs of Chicago and Atlanta, as well as Columbus, Ohio, Louisville, Ky., and rural North Carolina. Suspects have also surfaced in Indiana, Michigan, Minnesota and Pennsylvania.

Mexican drug cartels "are taking over our neighborhoods," Pennsylvania Attorney General Kathleen Kane warned a legislative committee in February. State Police Commissioner Frank Noonan disputed her claim, saying cartels are primarily drug suppliers, not the ones trafficking drugs on the ground.

For years, cartels were more inclined to make deals in Mexico with American traffickers, who would then handle transportation to and distribution within major cities, said Art Bilek, a former organized crime investigator who is now executive vice president of the crime commission.

As their organizations grew more sophisticated, the cartels began scheming to keep more profits for themselves. So leaders sought to cut out middlemen and assume more direct control, pushing aside American traffickers, he said.

Beginning two or three years ago, authorities noticed that cartels were putting "deputies on the ground here," Bilek said. "Chicago became such a massive market ... it was critical that they had firm control."

To help fight the syndicates, Chicago recently opened a first-of-its-kind facility at a secret location where 70 federal agents work side-by-side with police and prosecutors. Their primary focus is the point of contact between suburban-based cartel operatives and city street gangs who act as retail salesmen. That is when both sides are most vulnerable to detection, when they are most likely to meet in the open or use cellphones that can be wiretapped.

Others are skeptical about claims cartels are expanding their presence, saying law-enforcement agencies are prone to exaggerating threats to justify bigger budgets.

David Shirk, of the University of San Diego's Trans-Border Institute, said there is a dearth of reliable intelligence that cartels are dispatching operatives from Mexico on a large scale.

"We know astonishingly little about the structure and dynamics of cartels north of the border," Shirk said. "We need to be very cautious about the assumptions we make."

Statistics from the DEA suggest a heightened cartel presence in more U.S. cities. In 2008, around 230 American communities reported some level of cartel presence. That number climbed to more than 1,200 in 2011, the most recent year for which information is available, though the increase is partly due to better reporting.

Dozens of federal agents and local police interviewed by the AP said they have identified cartel members or operatives using wiretapped conversations, informants or confessions. Hundreds of court documents reviewed by the AP appear to support those statements.

"This is the first time we've been seeing it ? cartels who have their operatives actually sent here," said Richard Pearson, a lieutenant with the Louisville Metropolitan Police Department, which arrested four alleged operatives of the Zetas cartel in November in the suburb of Okolona.

People who live on the tree-lined street where authorities seized more than 2,400 pounds of marijuana and more than $1 million in cash were shocked to learn their low-key neighbors were accused of working for one of Mexico's most violent drug syndicates, Pearson said.

One of the best documented cases is Jose Gonzalez-Zavala, who was dispatched to the U.S. by the La Familia cartel, according to court filings.

In 2008, the former taxi driver and father of five moved into a spacious home at 1416 Brookfield Drive in a middle-class neighborhood of Joliet, southwest of Chicago. From there, court papers indicate, he oversaw wholesale shipments of cocaine in Illinois, Wisconsin and Indiana.

Wiretap transcripts reveal he called an unidentified cartel boss in Mexico almost every day, displaying the deference any midlevel executive might show to someone higher up the corporate ladder. Once he stammered as he explained that one customer would not pay a debt until after a trip.

"No," snaps the boss. "What we need is for him to pay."

The same cartel assigned Jorge Guadalupe Ayala-German to guard a Chicago-area stash house for $300 a week, plus a promised $35,000 lump-sum payment once he returned to Mexico after a year or two, according to court documents.

Ayala-German brought his wife and child to help give the house the appearance of an ordinary family residence. But he was arrested before he could return home and pleaded guilty to multiple trafficking charges. He will be sentenced later this year.

Socorro Hernandez-Rodriguez was convicted in 2011 of heading a massive drug operation in suburban Atlanta's Gwinnett County. The chief prosecutor said he and his associates were high-ranking figures in the La Familia cartel ? an allegation defense lawyers denied.

And at the end of February outside Columbus, Ohio, authorities arrested 34-year-old Isaac Eli Perez Neri, who allegedly told investigators he was a debt collector for the Sinaloa cartel.

An Atlanta attorney who has represented reputed cartel members says authorities sometimes overstate the threat such men pose.

"Often, you have a kid whose first time leaving Mexico is sleeping on a mattress at a stash house playing Game Boy, eating Burger King, just checking drugs or money in and out," said Bruce Harvey. "Then he's arrested and gets a gargantuan sentence. It's sad."

Because cartels accumulate houses full of cash, they run the constant risk associates will skim off the top. That points to the main reason cartels prefer their own people: Trust is hard to come by in their cutthroat world. There's also a fear factor. Cartels can exert more control on their operatives than on middlemen, often by threatening to torture or kill loved ones back home.

Danny Porter, chief prosecutor in Gwinnett County, Ga., said he has tried to entice dozens of suspected cartel members to cooperate with American authorities. Nearly all declined. Some laughed in his face.

"They say, 'We are more scared of them (the cartels) than we are of you. We talk and they'll boil our family in acid,'" Porter said. "Their families are essentially hostages."

Citing the safety of his own family, Gonzalez-Zavala declined to cooperate with authorities in exchange for years being shaved off his 40-year sentence.

In other cases, cartel brass send their own family members to the U.S.

"They're sometimes married or related to people in the cartels," Porter said. "They don't hire casual labor." So meticulous have cartels become that some even have operatives fill out job applications before being dispatched to the U.S., Riley added.

In Mexico, the cartels are known for a staggering number of killings ? more than 50,000, according to one tally. Beheadings are sometimes a signature.

So far, cartels don't appear to be directly responsible for large numbers of slayings in the United States, though the Texas Department of Public Safety reported 22 killings and five kidnappings in Texas at the hands of Mexican cartels from 2010 through mid- 2011.

Still, police worry that increased cartel activity could fuel heightened violence.

In Chicago, the police commander who oversees narcotics investigations, James O'Grady, said street-gang disputes over turf account for most of the city's uptick in murders last year, when slayings topped 500 for the first time since 2008. Although the cartels aren't dictating the territorial wars, they are the source of drugs.

Riley's assessment is stark: He argues that the cartels should be seen as an underlying cause of Chicago's disturbingly high murder rate.

"They are the puppeteers," he said. "Maybe the shooter didn't know and maybe the victim didn't know that. But if you follow it down the line, the cartels are ultimately responsible."

It being the day it is, let?s round up some of the better bits of airline news and writing today:

?

? Delta Air Lines is introducing double-decker armrests.

?Say goodbye to confusing elbow etiquette. Introducing the new Double Decker Armrest. More arm space, less elbow rubbing ? middle seats will never be the same again.?

? Southwest Airlines unveiled a hot air balloon?for commercial air transportation.

Said the carrier: ??Enjoy taking it slow with a scenic view while traveling from Boston to Denver. You will have a full 31 hours of seemingly never-ending ground-peeping, star-gazing, and gusty nap time. (DISCLAIMER: Travel time greatly depends on wind speed).?

? JetBlue Airways announced service to three new destinations: April River Airport (APR) in?Papua New Guinea; Ilford Airport (ILF) in?Manitoba, Canada; and Gold Coast Airport (OOL) in Coolangatta,?Australia. Put those three bag tags together, and you?re on quite a journey.

?They asked and we listened,? said Shirley Eugest, director of miscellaneous for?JetBlue?Airways. ?We?re all about meeting demand and our loyal customers told us they wanted to fly to these locales. We?re looking forward to serving these three new routes and introducing our signature product to the people of?Papua,?Ilford, and Coolangatta.?

? The website gadling.com has a series of exclusives, including that Hawaii wants to move to the other side of international date line, that Loch Ness travel officials made up the monster stories to attract tourists, that hotel mints are helping make us obese and that hunting humans is the No. 3 sport for the ultrawealthy.

? Gadling.com also has US Airways chairman and CEO Doug Parker announcing that he?s decided to call off the merger with American Airlines because he couldn?t deal with the issue of the airplane livery post-merger.

Among other goodies:

? Virgin America on its website says it?ll offer Main Canine Select for its animal friends. For dogs, it will provide special vents to reproduce that head-out-the-window feeling. In addition, ?Socialize at ?open air? lavatories, complete with mood-lit fire hydrants designed by Frank Gehry.?

Flying in a ?V? formation enables aircraft to utilize wake from the lead aircraft to pull the following aircraft ahead and reduce fuel burn. Flights first to depart PHX will take the ?lead bird? position, and as they reach their destinations, will drop from the formation and the next arriving aircraft will take the lead position in the ?V.? It is anticipated the new procedure will save approximately one million gallons of fuel a year. The test will run for one day only ? today, April Fools Day.?

? Oh, and JetBlue announced a no-joke special for the day: ?If you?re named April and flying JetBlue today, you?ll receive a JetBlue credit equal to the amount of the fare you paid for today?s flight, because JetBlue understands that this should be your day, not the fools. No fooling!?

(AP) ? After one of his assistant prosecutors was gunned down in January, Kaufman County District Attorney Mike McLelland carried a gun everywhere, even when walking the dog.

He was extra careful when answering the door at his home outside of Forney, about 20 miles east of Dallas. And a neighbor said a sheriff's deputy was stationed outside the home for about a month after the killing.

On Saturday, McLelland and his wife, Cynthia, were found shot to death in their house. Authorities haven't said much about their investigation, including whether they have any leads or a theory about why the couple was killed. But law enforcement throughout Texas is on high alert, and steps are being taken to better protect other DAs and their staffs.

Tarrant County District Attorney Joe Shannon said his staff has been cautioned, but he declined to discuss the specific security measures that have been taken. Dallas County District Attorney Craig Watkins declined to comment on the issue, citing safety concerns.

Harris County District Attorney Mike Anderson said he accepted the Houston sheriff's offer of 24-hour security for him and his family after learning about the slayings, mostly over concerns for his family's safety. Anderson said he also would take precautions at his office, the largest one in Texas, which has more than 270 prosecutors.

"I think district attorneys across Texas are still in a state of shock," Anderson said Sunday.

Kaufman County Sheriff David Byrnes said little at a brief news conference Sunday about the McLelland investigation, and he deflected questions about possible suspects. He said security would be stepped up at the courthouse in Kaufman, but he declined to say what other steps might be taken to protect the other prosecutors in McLelland's office. The DA's Office will remain closed Monday.

McLelland, 63, is the 13th prosecutor killed in the U.S. since the National Association of District Attorneys began keeping count in the 1960s.

The couple's slayings came less than two weeks after Colorado's prison chief was shot to death at his front door, apparently by an ex-convict, and a couple of months after Kaufman County Assistant District Attorney Mark Hasse was killed in a parking lot a block from his courthouse office. No arrests have been made in Hasse's slaying Jan. 31.

Byrnes would not give details Sunday of how the killings unfolded and said there was nothing to indicate for certain whether the DA's slaying was connected to Hasse's.

El Paso County, Colo., sheriff's spokesman Sgt. Joe Roybal said investigators had found no evidence so far connecting the Texas killings to the Colorado case, but added: "We're examining all possibilities."

Colorado's corrections director, Tom Clements, was killed March 19 when he answered the doorbell at his home outside Colorado Springs. Evan Spencer Ebel, a white supremacist and former Colorado inmate suspected of shooting Clements, died in a shootout with Texas deputies two days later about 100 miles from Kaufman.

McLelland himself, in an Associated Press interview shortly after the Colorado slaying, raised the possibility that Hasse was gunned down by a white supremacist gang.

McLelland, elected DA in 2010, said his office had prosecuted several cases against racist gangs, who have a strong presence around Kaufman County, a mostly rural area dotted with subdivisions, with a population of about 104,000.

"We put some real dents in the Aryan Brotherhood around here in the past year," he said.

In recent years, the DA's office also prosecuted a case in which a justice of the peace was found guilty of theft and burglary and another case in which a man was convicted of killing his former girlfriend and her 10-year-old daughter.

McLelland said he carried a gun everywhere around town, a bedroom community for the Dallas area. He figured assassins were more likely to try to attack him outside. He said he had warned all his employees to be constantly on the alert.

"The people in my line of work are going to have to get better at it," he said of dealing with the danger, "because they're going to need it more in the future."

The number of attacks on prosecutors, judges and senior law enforcement officers in the U.S. has spiked in the past three years, according to Glenn McGovern, an investigator with the Santa Clara County, Calif., district attorney's office who tracks such cases.

For about a month after Hasse's slaying, sheriff's deputies were parked in the district attorney's driveway, said Sam Rosander, a McLelland neighbor.

The FBI and the Texas Rangers joined the investigation into the McLellands' deaths.

McLelland and his wife, Cynthia, 65, were the parents of two daughters and three sons. One son is a police officer in Dallas. The couple had moved into the home a few years ago, Forney Mayor Darren Rozell said.

"Real friendly, became part of our community quickly," Rozell said. "They were a really pleasant, happy couple."
