Dengue fever emerges as major health threat in Gulf coast cities

Several cases of dengue fever, a potentially fatal viral disease transmitted by the bite of urban dwelling Aedes aegypti and Aedes albopictus mosquitoes, have recently been reported in the continental United States. Prevalent in Central America and the Caribbean, dengue fever's most common symptoms include fever, chills, headache, and body aches lasting several days. The disease's more threatening form, dengue hemorrhagic fever, can cause internal bleeding, loss of blood pressure, and death. Over the past five years, outbreaks of both forms of the disease have been reported in Texas and Florida.

Predator-released chemicals function as warning signals for egg-laying mosquitoes

A scientific breakthrough might assist in the fight against mosquitoes. New research carried out at the University of Haifa in collaboration with researchers from other universities has chemically identified, for the first time, compounds released by mosquitoes' natural aquatic predators that function as warning signals for egg laying mosquitoes. Introducing these natural chemicals into mosquito breeding sites will cause the mosquitoes to sense risk of predation to their progeny and avoid laying their eggs there.

Human impact on health of soil, and impact of unhealthy soil on society are intertwined, says LSU researcher

It may sound counterintuitive, but LSU Associate Professor of Chemistry Robert Cook has made a career out of studying the ways organic materials found in the environment, including soils, can either get dirty or stay clean. In fact, the National Science Foundation, or NSF, was so impressed with his efforts that the funding institute awarded Cook one of its most prestigious awards - the NSF CAREER award.

Greenwire/New York Times examine dengue vaccine development

Greenwire/New York Times reports on the growing number of cases of dengue worldwide, including the CDC's report last month that the virus has now been locally acquired in the continental U.S. for the first time in 65 years. "While a few cases were reported earlier, they were primarily in Americans who had caught the virus abroad or at the Texas-Mexico border," the news service writes.

Florida seeks new tools to stop dengue outbreak

While all eyes are on the Gulf oil spill, another natural disaster worsens as Key West Florida battles the first U.S. outbreak of dengue in 75 years. With over 30 confirmed cases (27 in 2009, 8 in 2010) and 5% of residents showing exposure to the mosquito-spread disease, Florida is seeking new tools to stop the emerging threat. Aiming to enhance their existing control program, the Florida Keys Mosquito Control District turned to SpringStar Inc in Woodinville, WA.

New method to synthesize drug candidates for testing

Some drugs may be more effective the longer they last inside the body. To prevent such drugs from being broken down too rapidly, pharmaceutical manufacturers often attach a fluorine-containing structure called a trifluoromethyl group. However, the processes now used require harsh reaction conditions or only work in a small number of cases, limiting their usefulness for synthesizing new drug candidates for testing.

New study that describes sequencing and analysis of body louse genome published

A global research team led by scientists from the J. Craig Venter Institute today published a new study in the Proceedings of the National Academy of Sciences describing the sequencing and analysis of the body louse genome. Lead author, Ewen Kirkness, Ph.D., JCVI, directed the sequencing and gene-finding efforts in the project. Detailed analysis of the genome was then conducted by a large international group of 71 scientists, coordinated by Barry Pittendrigh, University of Illinois, and Professor Evgeny Zdobnov, University of Geneva Medical School.

Parkinson’s disease linked to gene variant and pesticide: Study

Researchers from France reported in their new study that bad genes and exposure to certain banned pesticides could be blamed for development of Parkinson’s disease in men. In their study, published in the Archives of Neurology journal they show that men exposed to pesticides such as DDT and who had inherited genes for Parkinson’s disease were three and a half times more likely to develop Parkinson's than those with the normal version of the gene.

New bacterial strain could help in long-term cleanup of oil spills

Researchers have discovered a new strain of bacteria that can produce non-toxic, comparatively inexpensive "rhamnolipids," and effectively help degrade polycyclic aromatic hydrocarbons, or PAHs - environmental pollutants that are one of the most harmful aspects of oil spills.
