A tropical tree-dwelling lizard has succeeded in a problem-solving test by learning to associate the color of a cap with a food reward, contesting the stereotype that reptiles are extremely limited cognitively compared to birds and mammals. The cognitive abilities of reptiles have rarely been studied.

In a color discriminating task, the lizards learned to flip over the correctly colored cap to reveal a worm hidden underneath. The experiment was conducted at Duke University and the results, published in the Royal Society journal Biology Letters, suggest that the problem-solving abilities of reptiles may be greater than previously thought.

The Puerto Rican lizard, (an anole), used in the study, is a well-studied species, known to excel at foraging food by being acutely aware of movement. Several lizards of this species were collected from Puerto Rico for the experiment.

Researches first wanted to determine if the six lizards used in the study were able to figure out how to flip off the cap to obtain the food. The agile reptiles quickly learned to use one of two ways to move the cap: they closed their jaws on the edge of the cap and dragged it off the food, or ran into the cap with their heads, tipping it over and grabbing the food.

The lizards were then given a choice between two caps; one was blue and the other was yellow and blue; under only one was the food reward of a worm. They quickly learned to distinguish which cap had the reward.

“They learned to associate the color of the [cap] with a food reward,” said Manual Leal, the Duke University researcher who led the study. Their success on a test that is based on worms and usually used on birds was “completely unexpected,” he said.

The lizards solved the problem in fewer tries than birds needed to flip the correct cap and pass the test, Leal explained. Lizards get just one chance per day because they eat less, while birds usually get up to six chances a day. Thus a mistake by a lizard means it must remember until the next day how to correct the mistake, Leal said.

And when the color of the caps was switched, after a few mistakes two of the lizards were able to figure out the trick. “We named these two Plato and Socrates,” said Leal.

Jonathan Losos, a biologist at Harvard University not involved in the study, said Leal’s experiment demonstrates that when faced with a new situation, most of the lizards were able to solve the problem. They had the ability to figure out the trick and disregard their previous learning; a sign of a cognitively advanced animal that some mammalian species cannot easily do.

The results “should cause researchers to re-evaluate what they think they know about the evolution of animal cognition,” Losos said.

Japanese multinational company Fujitsu launched a website for a dog pedometer which allows customers to monitor their dog’s health online. The device measures data while attached to the dog’s collar. Customers are also able to add more data to the website manually, then it displays the complete set of data graphically. Fujitsu launched the website today (Tuesday) and plans to start the sales in Japan tomorrow (Wednesday).

The pedometer is called “Wandant”, from Japanese “Wan” equivalent to “woof”, and the “dant” of “pendant”. The latter refers to the pedometer, because it is attached to a dog collar. The users can transfer data to an Android phone using a touch-card to make it available online.

Fujitsu said Wandant would be the first cloud-based dog health-care service.

The data include walking, temperature, and shaking motion statistics. The users can manually enter additional data such as food quantities, weight, custom notes, and photos.

Fujitsu said, “The data are presented graphically on a custom website that makes trends in the dog’s activities easy to understand at a glance. This helps owners get a stronger sense of their dog’s health, while enabling communication with the dog.”

Three men are currently seeking the presidential nomination of the Reform Party of the United States of America: small business owner Andre Barnett, Earth Intelligence Network CEO Robert Steele, and former college football coach Robby Wells. Wikinews reached out to these candidates and asked each of them five questions about their campaigns. There were no space limits placed on the responses, and no candidate was exposed to another’s responses before making their own. The answers are posted below in unedited form for comparison of the candidates.

The Reform Party is a United States third party that was founded in 1995 by industrialist Ross Perot. Perot ran as the party’s first presidential nominee in 1996, and won over eight percent of the popular vote, the highest percentage for a third party candidate since. In 1998, professional wrestler Jesse Ventura ran on the Reform Party ticket and was elected Governor of Minnesota. The party fell in prominence during the lead-up to the 2000 presidential election when it was plagued by infighting between ideological factions. In 2000, paleoconservative Pat Buchanan won the presidential nomination, and went on to receive only 0.4 percent of the popular vote in the general election. In 2004, the party opted to endorse consumer advocate Ralph Nader, but ended the year nearly bankrupt. In 2008, Ted Weill won the party’s presidential nomination, but appeared on the ballot in only one state and won a total of 481 votes.

The party is currently trying to rebuild and has opened several new state chapters. They will attempt to appear on the ballot in more states for the 2012 presidential election. The party is expected to nominate its presidential ticket during the National Convention this summer.

Maureen Faibish of 711 Lincoln Way San Francisco, CA was arrested on June 24, 2005 on the charge of child endangerment in the actions leading up to the death of her son, 12-year-old Nicholas Faibish, who was mauled by one or both of her two pit bull dogs, Rex 2 and Ella.

Nicholas was discovered dead in the front bedroom of her home at approximately 15:15 PDT on June 3, 2005, by his mother, who had left the house to run some errands. She had locked her son in the basement to keep him away from the dogs. “I put him down there, with a shovel on the door.”, Faibish said in a telephone interview to the San Francisco Chronicle. “He had a bunch of food. And I told him, ‘Stay down there until I come back.’ Typical Nicky, he wouldn’t listen to me.”

Faibish stated that she believes that her son had walked in when Rex 2, a male pit bull, was attempting to mate with Ella, a female pit bull who was in heat at the time. She stated that Rex 2 had been acting possessively prior to the incident. A police officer shot and killed Ella in order to gain entry to the apartment. Rex 2 was captured and removed to an animal shelter. “The police killed the wrong dog if you ask me.”, Faibish said.

A 1965 Volkswagen minibus that was stolen in 1974 has been recovered by customs agents in Los Angeles. The vintage minibus was in pristine condition, valued at $25,000, and was found during a routine inspection of a shipping container scheduled for departure to The Netherlands. A routine computer database search on its vehicle identification number flagged it as having been stolen from a vehicle upholstery shop in Spokane, Washington on July 12, 1974. A custom restoration business in Arizona was attempting to deliver it to overseas clients last month when authorities intercepted the vehicle.

The theft appeared on the National Insurance Crime Bureau database, which is used by border authorities and contains all stolen vehicle records. Most police databases remove unsolved vehicle thefts after five years.

The California Highway Patrol does not suspect the restorer of wrongdoing, according to investigating officer Mike Maleta. Possession of the vehicle apparently changed several times. Police in Spokane have not yet located the rightful owner, whose identity has not been released to the press. Maleta hopes that a trail of registration documents and interviews will uncover the thief.

The Allstate insurance company paid $2500 shortly after the theft occurred and wants to take possession of the vintage minibus. Allstate spokeswoman Megan Brunet expects that after the necessary paperwork is processed the firm will sell it at auction.
