In the first study of its kind, researchers at the Yerkes National Primate Research Center and Emory Vaccine Center, Emory University, have developed a multidisciplinary approach involving immunology, genomics and bioinformatics to predict the immunity of a vaccine without exposing individuals to infection.
Few things sting like a mosquito's bite -- especially if that bite carries a disease such as malaria. If researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well.
By Kevin Krolicki DETROIT (Reuters) - Louisiana, struggling to rebuild from Hurricane Katrina, now faces a potential scourge of mosquitoes as insects hatch in storm-created breeding grounds, scientists said on Monday.

In one of the first molecular studies of the human antibody response to yellow fever, Howard Hughes Medical Institute (HHMI) researchers and their colleagues have found the crucial bit of virus that people's immune systems need to spot and quash this often-fatal re-emerging disease.
For almost an hour at a time, twice a day, two days a week in the deep heat of a Louisiana summer, Dawn Wesson stands in an urban backyard like a human scarecrow, arms spread wide, trying to attract mosquitoes. The two species of mosquitoes that can transmit yellow fever and dengue fever will be attracted to her odor and try to land.
Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...
