Decoding dengue

(Duke-NUS Graduate Medical School Singapore  16 July 2014) Scientists have discovered a new pathway the dengue virus takes to suppress the human immune system. This new knowledge deepens our understanding of the virus and could contribute to the development of more effective therapeutics.

New potential way to control spread of insect-borne disease

EurekAlert 17-Jul-2014

A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.” The advance could potentially lead to powerful new ways of combating malaria and other insect-borne diseases, controlling invasive species and promoting sustainable agriculture.
Representing the Wyss Institute for Biologically Inspired Engineering at Harvard University, Harvard Medical School, Harvard School of Public Health, the Massachusetts Institute of Technology (MIT), Boston University, the Woodrow Wilson Center, and Arizona State University, the team includes scientists working in disciplines ranging from genome engineering to public health and ecology, as well as risk and policy analysis.

Scientists discover way to stop malaria parasite in its tracks

Sydney Morning Herald Bridie Smith July 17, 2014

The global race to develop the next generation of malaria drugs has been given a boost after Australian scientists discovered how to starve the malaria parasite of nutrients, effectively killing it before it takes hold.
The breakthrough, published in Nature on Thursday, comes at a time when the parasite has developed a resistance to anti-malarial drugs, with researchers and health care workers growing increasingly desperate for replacement treatments.

Control strategy for Dengue, malaria increases risk of West Nile virus

(Penn State 10 July 2014) Mosquitoes infected with the bacteria Wolbachia are more likely to become infected with West Nile virus and more likely to transmit the virus to humans, according to a team of researchers.

Malaria parasite ‘hides in the bone’

BBC News Helen Brigs 9 July 2014

Parasites infected with malaria can hide inside bone marrow and evade the body’s defences, research confirms.  The research, published in Science Translational Medicine, fills a “key knowledge gap” in the biology of the disease, say scientists at Harvard.

Torres spraying mission to tackle disease-spreading mosquitoes

ABC News July 3, 2014

The state and federal governments will spend $4 million trying to eradicate two disease-spreading mosquito species from the Torres Strait.

The Aedes Aegypti mosquito transmits dengue fever and the Asian Tiger mosquito can also infect people with chikungunya and Japanese encephalitis.  Continue reading…

Fine-scale climate model projections predict malaria at local levels

(Penn State 2 July 2014) Fine-scale climate model projections suggest the possibility that population centers in cool, highland regions of East Africa could be more vulnerable to malaria than previously thought, while population centers in hot, lowland areas could be less vulnerable, according to a team of researchers. The team applied a statistical technique to conventional, coarse-scale climate models to better predict malaria dynamics at local levels.
