A promising step toward controlling Zika virus and dengue fever

UCLA scientists and colleagues identify structure of a molecule that kills mosquitoes carrying malaria and West Nile

Five UCLA researchers were part of an international team that has used X-rays to reveal the structure of a molecule that is toxic to disease-carrying mosquitoes. The findings move the scientific world one step closer to genetically engineering a toxin that would be lethal to species that carry dengue fever and the Zika virus. (more…)

Creating a malaria test for ancient human remains

Ancient malaria patients, the anthropologist will see you now.

A Yale University scientist has developed a promising new method to identify malaria in the bone marrow of ancient human remains. It is the first time researchers have been able to establish a diagnostic, human skeletal profile for the disease, which is transmitted by mosquitoes and continues to infect millions of people a year.

Breaking Dengue Fever

Like malaria, dengue fever is an infectious disease transmitted by mosquitoes. Unlike malaria, there is no vaccine for it. As many as 100 million people contract dengue each year, but MSU researcher Zhiyong Xi is working to change that.

Among the estimated 2.5 billion people at risk for dengue, more than 70 percent live in Asia Pacific countries, which spurred Xi to establish a collaborative research institute at Sun Yat-sen University in Guangzhou, China. (more…)

Making Blood-Sucking Deadly for Mosquitoes

*Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a UA team of biochemists found.*

Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered.

The approach could be used as an additional strategy in the worldwide effort to curb mosquito-borne diseases like dengue fever, yellow fever and malaria. (more…)

West Nile Virus More Prevalent in Low-income Neighborhoods, Study Finds

Low-income neighborhoods appear to be the most susceptible to West Nile virus, a mosquito-transmitted disease that is linked to more than 1,000 deaths since in the United States since 1999, according to new UCLA-lead research.

Using data on infected humans and mosquitoes from the West Nile virus hotspot of Orange County, Calif., from 2005-08, scientists found that per-capita income and other economic conditions were the single greatest predictor of occurrence, explaining 85-95 percent of the variation. While economic conditions have previously been linked to disease, the study is the first to use a rigorous statistical model.  (more…)
