...restaurants led the pack with 63 violations among them, most of which had to do with unclean food surfaces; other transgressions included spoiled food and inadequate hand-washing by employees. Austin, Texas, eateries came in second, with 58 violations, including a leaking roof over a food-prep area and rodent droppings on utensils. Most of the city's violations, however, had to do with food kept at improper temperatures...
...Over the past 60 years, scientists have figured out what works best in what models. The vast majority of animal testing [today] is in rodents, either rats or mice. Rodents, particularly mice, have very short life spans, so you can see how a compound would react in a young animal, then in the same geriatric animal, and then in the next-generation animal, all in a time frame that is reasonable. Then if a product or a compound is determined to be safe in a rodent, another species is used. For example, if it's a neurological compound, oftentimes...
Plague lives in many rodent species, and is most often transferred to humans by the animals' fleas. Scientists know which regions of the world harbor infected animals, but they are only just beginning to understand the dynamics of plague infection. Its spread depends not just on Yersinia pestis but also on interactions among rodents and, crucially, on contact between humans and wildlife. Madagascar is a good example. For decades, plague was restricted to the highlands, according to a 2004 paper by researchers in Madagascar, Senegal and France. But it showed up on the coast in 1991, when the Asian shrew...
...issues are the task of any local government. But few places bring quite as much passion to the day-to-day problems of city life as Cambridge does. Case-in-point: the rat problem. Though the councillors themselves have rarely delved into discussions of the city’s rodent infestation in the past two years, citizen speakers are often eager to bring the pest problem to the councillors’ attention. The Cambridge Department of Public Works (DPW) operates a rat hotline, where citizens can report rat sightings or get help keeping rats from entering their house. DPW also...
...crops, unwittingly creating an alluring new habitat for the vole. "Since the late 1980s we have seen occasional cycles in which large numbers of voles, drawn by these new food sources, have appeared in the northern part of Castilla-León," says biologist Juan José Luque, a rodent specialist at the University of Valladolid. "What's extraordinary this year is that, instead of declining over the winter, the population exploded...
