Help NASA track mosquitoes, reduce disease outbreaks
Washington, July 3 : NASA has invited citizen scientists to help them track mosquitos known to carry and spread diseases like Zika, West Nile Virus and malaria to create new forecast models that can predict the spread of these diseases.
"We do not have enough information on the geographic distribution of mosquito and time-variation in their populations. If a lot of people participated in this citizen science initiative worldwide, it will help fill in gaps and that would help our work," Assaf Anyamba, a scientist from Universities Space Research Association at NASA's Goddard Space Flight Center in Greenbelt, Maryland, said in a statement.
NASA scientists have initiated the work with DEVELOP team -- part of NASA's Applied Sciences Programme, which addresses environmental and public policy issues -- to create the models.
The teams blended the citizen science data with NASA satellite observations of land surface temperatures, humidity, soil moisture, elevation, vegetation and precipitation.
The data were then used to create an interactive, open-source map on Google Earth Engine to improve prediction models for disease-carrying mosquitoes.
Early results have showed that vegetation, humidity and soil moisture made it easier for mosquitoes to thrive during the summer months. During the winter, elevation played a stronger role in creating mosquito-friendly habitats.
The public can help track mosquitoes by downloading an app called GLOBE Observer, and then collect data over the summer using the Mosquito Habitat Mapper tool in the app, NASA said.
The app guides users through the process of identifying and eliminating mosquito breeding sites in order to reduce mosquito populations in their immediate surroundings.
More citizen science data from more areas of the world could help, the US space agency noted.
"Knowing the mosquito species and their approximate populations at a given time provides useful information on the potential of occurrence of a particular pathogen, or disease transmission," Anyamba said.

Mumbai-Pune Expressway connecting link now fully operational
Mumbai (PTI): The Mumbai-bound carriageway of the Mumbai-Pune Expressway connecting link was opened to vehicular traffic on Saturday noon after a delay caused by the dismantling of inauguration infrastructure and cleaning work, a day after the Pune section became operational.
The 13.3 km-long "missing link", which bypasses a section of the Bhor Ghat stretch of the expressway and cuts travel time between Mumbai and Pune by 25 to 30 minutes, was inaugurated a day earlier by Chief Minister Devendra Fadnavis in the presence of Deputy CMs Eknath Shinde and Sunetra Pawar.
The Pune-bound carriageway of the corridor was opened to traffic immediately; however, the Mumbai-bound section remained closed to traffic for several hours after the inauguration.
An official of the Maharashtra State Road Development Corporation told PTI on Saturday that the opening of the Mumbai-bound carriageway was delayed mainly due to the dismantling of the inauguration infrastructure and cleaning work.
The removal of the stage and other decorations was completed in the morning. The work to load and transport the material slightly delayed the opening of the carriageway.
Vehicular movement on the carriageway began after all the remaining material was cleared and road cleaning was completed, the official added.
The expressway control room said that despite significant vehicular movement, the access-controlled highway has not witnessed any major traffic snarls since Friday evening, after the Pune-bound carriageway of the missing link was opened to traffic.
The Missing Link project connects Khopoli (in Raigad) on the Mumbai side to Kusgaon near Lonavala in Pune district and is expected to make the expressway fully access-controlled, easing congestion in the ghat section.
Developed by the MSRDC and dubbed an "engineering marvel", the project includes two tunnels, two viaducts and a cable-stayed bridge over Tiger Valley. It bypasses the steep, accident-prone ghat section, where frequent traffic snarls are reported during weekends and on public holidays.
