The researchers from the university's Bloomberg School of Public Health studied nearly 300 Wild Norway rats -- also called wharf rats, sewer rats or brown rats -- that they trapped from 11 residential areas of the city. They then conducted genetic studies to see how the rats were related. The scientists found that East Baltimore rats...

Britain's poison-resistant rat population has risen to an estimated 80 million -- an increase of more than 200 percent since 2007, scientists said. Genetic mutations have produced super rats with DNA that protects against common pesticides, said Robert Smith, a researcher at the University of Huddersfield. Natural selection means that when you have a rat population in your town, poison will kill the ones that aren't resistant, the ones that survive may have the gene, they then have babies who...

Improving the environment in which rats are reared can significantly strengthen the physiological process of wound healing, according to a report in the online, open-access, peer-reviewed journal PLoS ONE. Researchers from the Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital (MGH) and Shriners Burns Hospital found that giving rats living in isolation the opportunity to build nests led to faster and more complete healing of burn injuries than was seen in...

Students and faculty at Kentucky's Spalding University marked the end of finals week with the annual Running of the Rodents, a race exclusively for rats. The race, which has been a tradition at the school for 37 years, involves rats trained by teams of students and faculty to race around a small oval track for a rodent-friendly prize -- a garland made from fruit-flavored cereal, the Louisville (Ky.) Courier-Journal reported Thursday. This year's event, dubbed CelebRATy, bore a Hollywood theme...

Researchers have discovered a new species of rat in the mountains of the southern Philippines. Discovered in 2006 by US and Filipino researchers, Hamiguitan batomys, also known as hairy-tailed rat, weighs about 6.2 ounces and lives 3,117 feet above sea level on Mount Hamiguitan on Mindanao island. "The unusual geological history of eastern Mindanao leads us to predict that additional species currently unknown to anyone except local residents are likely to live there," Lawrence Heaney,...

A research project at Rice University has brought scientists to the brink of comprehending a long-standing medical mystery that may link cardiovascular disease, osteoporosis and perhaps even Alzheimer's disease. And for that, we can thank the rat.The recent paper in Artery Research by Rice evolutionary biologist Michael Kohn and his team reports they have found that common rats with a genetic mutation have developed a resistance to rat poison, aka warfarin. That's good news for the rats,...
