Published August 26, the paper highlights how daily commuting patterns in mega-cities may be a critically overlooked factor in understanding the resurgence of mosquito-borne diseases such as dengue fever, infecting 50-100 million people annually.
"Even a small number of infected people who remain active can move a virus such as dengue between different parts of the community, where it will be picked up by mosquitos and, after an incubation period, be passed on to another unsuspecting passerby," says Kapan. "Our research examined whether the standard practice of eliminating mosquito vectors at residences would be sufficient to control dengue if other areas in the community still had several large patches of mosquitos that could become infected by commuters."
To undertake this study, Kapan teamed up with mathematician Ben Adams from the University of Bath (UK), with support of UH Mânoa's Pacific Center for Emerging Infectious Diseases Research Center of Biomedical Research Excellence program (http://www.hawaii.edu/pceidr/), and as participating faculty in UH Mânoa's National Science Foundation Integrative Graduate Research Traineeship (IGERT) in Ecology, Conservation and Pathogen Biology (http://www2.jabsom.hawaii.edu/igert/).
"Our primary objective with this paper is to prompt researchers, public health practitioners and others concerned with vector control to look beyond the traditional epidemiological definition of a transmission cluster based on home address, and consider novel ways to control community transmission of vector-borne diseases that account for great morbidity and mortality worldwide," says Kapan. "Even a short visit to an infected patch of mosquitos, say at a lunch venue or open market, may be enough to keep the virus circulating."
Adds Adams, "When someone gets infected we need to look at their recent travel patterns to figure out from which group of mosquitoes they got the disease, and to which groups they may have passed it on."
Kapan works on this and other transdisciplinary research focused on applied evolution, ecology and insect genomics at the Center for Conservation and Research Training (CCRT), a research and training arm of the UH Mânoa Pacific Biosciences Research Center.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
