encode communicative signals in their auditorysystems. In paper 4aPP1, Bradford May of Johns Hopkins University ( firstname.lastname@example.org )will discuss a study of how cats convert vowel sounds into patterns of nerve-cell firings for varying leve...
Protein Implicated In Multiple Sclerosis

MS symptoms, Trotterhas shown. The protein has been largely ignored, however, because it doesn'tdissolve in water and therefore is hard to study. In 1991, Trotter's group was the first to show that human white bloodcells or lymphocytes recogn...

in South America andAfrica to be more closely related. But this animal found in Madagascar -- anisland off the southeast coast of Africa -- is more closely related to animalsfound half way around the world." The researchers suspect that a la...
