Washington, May 27 (ANI): In what may have important implications for controlling diseases that spread from rats to humans, Johns Hopkins scientists have found that rodents spend the majority of their lives close to their homes.
The researchers have also observed that some rodents may, in the face of danger, travel as far as seven miles to repopulate abandoned areas.
Wild Norway rats-also called wharf rats, sewer rats or brown rats-can weigh nearly 2 pounds and transmit a variety of diseases to humans.
Even though expensive eradication efforts have been made in Baltimore, point out the researchers, the number of rats there has remained unchanged over the past 50 years.
With a view to finding out why such drives have failed to eradicate rats from Baltimore, the researchers trapped about 300 rats from 11 residential areas and conducted genetic studies to see how the rats were related.
They found that East Baltimore rats are separated from their unrelated West-side counterparts by a large waterway known as the Jones Falls. Within these hemispheres, rat families form smaller communities of about 11 city blocks.
Each community is further divided into neighborhoods that span little more than the length of an average alley. And to a city rat, this is home sweet home.
Based on their observations, the researchers have come to the conclusion that while rats rarely migrate, neighborhood eradication efforts may backfire by encouraging the rodents to repopulate other areas and further spread disease.
They believe that the best solution may be to tackle the problem on a much larger scale-perhaps by targeting entire families at once.

Obama says poor bowling skills make him a likely candidate for Special Olympics
Washington, Mar.20 (ANI): President Barack Obama has attracted controversy again by saying that his poor bowling skills make him a likely candidate for the Special Olympics.
His spokesman, however, quickly said Obama did not mean any offense by his comment.
According to Politico, the late-night turn is a political risk for a president overseeing a recession.
Obama has attracted some criticism for it already, but he shrugged it off just a few hours before he appeared on “The Tonight Show” with Jay Leno in California.
Obama sought to mock his lackluster bowling skills by saying that he recently bowled a score of 129 in the White House bowling alley.
After the show’s taping and en route back to Washington on Air Force One, Deputy Press Secretary Bill Burton told reporters that Obama had “made an offhand remark making fun of his own bowling that was in no way intended to disparage the Special Olympics.”
“He thinks that the Special Olympics are a wonderful program that gives an opportunity to shine to people with disabilities from around the world,” Burton said.
Obama’s comments came on the same day that he had appeared with California First Lady Maria Shriver, an early supporter, whose mother Eunice Kennedy Shriver founded the athletic competition for the disabled in 1968.
Obama used much of his appearance on the comedy show to discuss the economy but sought to get in some light-hearted quips toward the end of the taping.
He said he had been working on his bowling game just below his new residence and recently rolled a 129.
“That’s very good, Mr. President,” cracked host Jay Leno
“It’s like – it was like Special Olympics, or something,” the president replied. (ANI)
