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. (IANS)

Delhi to get new QR-based driving livenses and registration certificates.

In a step towards digitisation of the system, Delhi Transport Department will soon issue QR based Smart cards for driving licenses (DLs) and registration certificates (RCs).

As per a statement, the new driving licence will have an advanced microchip with features like Quick Response (QR) code and Near Field Communication (NFC). The new RC will have the owner's name printed on the front while the microchip and the QR code would be embedded at the back of the card.

The cards earlier had embedded chips, but chip reader machines were not available in the required quantity with both the Delhi Traffic Police and the Enforcement Wing of the Transport Department. Moreover, chips were designed and implemented by the states concerned, which resulted in difficulties in reading the chip and retrieving information, especially in case of defaulters.

"Now with the QR based smart card, this issue is resolved. This will enable unification in linking and validating one's information to smart cards with Sarathi and Vahan, the two web-based databases of all driving licenses and vehicle registrations," the release added.

The QR is also being implemented nationwide, the QR code reader is easily procurable and will do away with the requirement of any manual intervention altogether. The new cards will also allow two specific materials for their card manufacturing -- PolyVinyl Chloride or PVC, or PolyCarbonate which is slightly more expensive but more durable. (Card Size - 85.6mm x 54.02 mm; Thickness minimum 0.7 mm)

An October 2018 notification of the Ministry of Road Transport and Highways (MoRTH) had made changes to the Driving License and Registration Certificate. The new Smart card based DL and RC, will have chip based/ QR code based recognition system. At the same time, documents such as driving license or registration certificates in electronic formats on DigiLockers and mParivahan were also made valid in place of physical documents and treated at par with original documents.

The QR code also has an added advantage of acting as a safety feature on the smart card. The department will be able to retain records and penalties of the DL holder for up to 10 years on the VAHAN database as soon as a driver/ owner's Smart card is confiscated. The new DLs will also help the government in maintaining records of differently-abled drivers, any modifications made to the vehicles, emission standards and the person's declaration to donate organs.

LONDON — A work by British street artist Banksy that sensationally shredded itself just after it sold at auction three years ago fetched almost 18.6 million pounds ($25.4 million) on Thursday — a record for the artist, and close to 20 times its pre-shredded price.

"Love is in the Bin" was offered by Sotheby's in London, with a presale estimate of 4 million pounds to 6 million pounds ($5.5 million to $8.2 million).

WASHINGTON — Suspected ransomware payments totaling $590 million were made in the first six months of this year, more than the $416 million reported for all of 2020, U.S. authorities said on Friday, as Washington put the cryptocurrency industry on alert about its role in combating ransomware attacks.

The U.S. Treasury Department said the average amount of reported ransomware transactions per month in 2021 was $102.3 million, with REvil/Sodinokibi, Conti, DarkSide, Avaddon, and Phobos the most prevalent ransomware strains reported.
