Researchers have developed a Covid-19 testing strategy that can streamline the process of identifying cases, tracking variants, and detecting co-infecting viruses. Currently, separate assays and complex workflows are involved in each of the diagnostic procedures, with analyses typically performed in highly specialized facilities.

The team from the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia has now combined all three kinds of tests into a single procedure that should allow for point-of-care tracking of Covid-19 and the many emerging variants of SARS-CoV-2.

“Our all-in-one test provides a promising integrated solution for rapid field-deployable detection and mutational surveillance of pandemic viruses,” said the study’s lead author Mo Li, a stem cell biologist from KAUST.

The new test takes advantage of a recent genetic method (called recombinase polymerase amplification) and a next-generation portable sequencer to quickly detect the presence of viral sequences and provide read-outs — in up to 96 patient samples at a time.
Li’s team, in collaboration with researchers from Saudi Arabia, the US, and Spain, designed the test to decode five segments of the SARS-CoV-2 genome, each chosen to help guide variant track. They also incorporated assays for three common respiratory viruses that can cause symptoms similar to Covid-19.

The team validated the technique — termed NIRVANA — using nose and throat swabs from people suspected of having SARS-CoV-2 infection. They also tested wastewater samples collected from municipal sewage at KAUST to show how the method could allow for population-level surveillance of SARS-CoV-2 and other viruses.

“NIRVANA can rapidly diagnose multiple viral infections in a high-throughput manner, it can simultaneously detect the virus and report its mutations,” said Chongwei Bi, a doctoral student at KAUST. (IANS/JC)

Killer Smog in Delhi.

Developed by the Indian Institute of Tropical Meteorology (IITM), Pune, a Decision Support System (DSS) that extends the ability of the existing air quality early warning system (AQEWS) to have decision-making capability for air quality management in Delhi-NCR was launched on Tuesday.

The website for the DSS (https://ews.tropmet.res.in/dss/) is designed to help the Commission for Air Quality Management for NCR and Adjoining Areas (CAQM) by delivering quantitative information about the contribution of emissions from Delhi and its 19 surrounding districts; the contribution of emissions from eight different sectors in Delhi; and the contribution from biomass-burning activities in the neighbouring states.

These information would assist in managing the air quality in a timely manner, a release from the Ministry of Earth Sciences said.

The need was stated by the CAQM, which was formed by the Ministry of Environment, Forest and Climate Change, during a meeting held in January 2021.

Recently, the Commission reviewed the progress made by IITM and had in principle approved the current version of DSS for air quality management in the Delhi-NCR. The IITM has also developed a new website for DSS with the entire system made operational, the release said.

Union Minister of State for Earth Sciences, Jitendra Singh, while launching the website for AQEWS on the occasion of 'Azadi Ka Amrit Mahotsav' week organised by the Ministry of Earth Sciences, said, "DSS is a significant contribution to 'Azadi Ka Amrit Mahotsav' on behalf of MoES and IITM and suggestions are invited on this issue."

The website also has a feature whereby the users can create their own emission reduction scenarios (from 20 different districts, including Delhi) so as to examine the possible projected improvement in air quality in Delhi for the next five days.

"This information would explicitly highlight the most important emission sources responsible for the degradation of air quality in Delhi and suggest possible solutions to ameliorate the same. With a plethora of quantitative data, the AQEWS integrated with DSS could become a user-friendly tool for air-quality management in and around Delhi," the release said. (IANS/JB)

On the first day of the two-day meeting of BJP and Rashtriya Swayamsevak Sangh (RSS) leaders on Tuesday, discussions were held on important issues related to education and the National Education Policy-2020

On the first day of the two-day meeting of BJP and Rashtriya Swayamsevak Sangh (RSS) leaders on Tuesday, discussions were held on important issues related to education and the National Education Policy-2020. Apart from senior RSS leader Suresh Soni, representatives of various organisations associated with the Sangh Parivar -- working in the field of education -- were present in the meeting in New Delhi.

According to sources, Union Education Minister Dharmendra Pradhan, who attended the meeting on behalf of the government, shared information related to the National Education Policy-2020 and the government's policy on important issues related to the education sector. Pradhan also shared details of the efforts being made by the government in the field of education.

Discussions were also held regarding the impact of the situation arising out of Corona and how much it has affected the education sector. In the meeting, the RSS leaders asked several questions and provided suggestions to the Union Minister regarding the education policy of the government.

According to the sources, RSS wants the policy to be implemented expeditiously. All aspects related to the policy were discussed in Tuesday's meeting. On the second and the last day of the meeting on Wednesday, special issues related to education will be discussed in which representatives of various organisations of the Sangh, Union Ministers and several BJP leaders will be take part.

Meanwhile, in order to convey its point of view to the government on various issues, the Sangh keeps on calling such coordination meetings related to specific issues, in which RSS representatives -- working in that particular area -- provide feedback to the government. (IANS/JB)
