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.

KSRTC introduces gender ticketing in buses across Kerala
Thiruvananthapuram (PTI): The KSRCTC on Saturday began implementing gender ticketing in buses operating across the state.
According to a Kerala State Road Transport Corporation (KSRTC) circular issued on Friday, the gender ticketing system is intended to record whether a passenger is a woman, a man or a child in tickets issued on KSRTC buses from Saturday.
To facilitate the system, Electronic Ticketing Machines (ETMs) have been updated.
The circular stated that conductors in all KSRTC depots should record the gender category of passengers while issuing tickets through the ETMs.
Options for women, men, and children have been included in the ETMs to identify passenger categories when issuing tickets.
The printed tickets generated by the ETMs will also indicate the passenger's category, officials said.
The UDF had promised free KSRTC travel for women across the state during the Assembly election campaign.
UDF, which won 102 of 140 seats, would soon form the government after the Congress party finalises the discussion on the next Chief Minister.
The introduction of gender ticketing is being viewed as an effort to estimate the number of women travelling daily on KSRTC buses before implementing the poll promise.
Some conductors have reportedly raised concerns over the additional time required to record passenger details, especially during rush hours.
