(PhysOrg.com) -- Bed bugs, once nearly eradicated in the built environment, have made a big comeback recently, especially in urban centers such as New York City. In the first study to explain the failure to control certain bed bug populations, toxicologists at the University of Massachusetts Amherst and Korea’s Seoul National University show that some of these nocturnal blood suckers have developed resistance to pyrethroid insecticides, in particular deltamethrin, that attack their nervous systems. http://phys.org/news150651765.html Biology Thu, 08 Jan 2009 15:42:45 EST news150651765 What if someone told you turkey doesn't make you tired, or that you nails really don't keep growing after you die? http://phys.org/news150573421.html Medicine & Health Wed, 07 Jan 2009 17:57:01 EST news150573421 An innovative approach for implanting a new aortic heart valve without open-heart surgery is being offered to patients at NewYork-Presbyterian Hospital/Columbia University Medical Center.
