Science & Technology Current Affairs - 2020

Science & Technology Current Affairs 2019-2020 category comprises current affairs with all important national / international updates in science and tech and events for the year 2019-2020 for UPSC, States, Civil services, SSC and other competitive examinations of India and States.

Funding approved by DST to develop Nasal Passage Gel for COVID-19

The Department of Biosciences and Bioengineering and IIT Madras have developed a nasal passage gel that will inactivate COVID1-9. The funding to support the technology is to be provided by SERB (Science and Engineering Research Board), a statutory body operating under Department of Science and Technology.

What is the plan?

The team formed from the two institutes will work on two approaches. They are as follows

Plan I

Under one approach, the plan is to create a causative agent that will prevent the virus from binding to the host cells. This method will reduce the probability of the host cells being infected. Later the viruses are inactivated using a drug or other technology. This technology will only support prevention of binding.

Plan II

Another approach is to inactivate the virus by trapping them. This method traps the virus similar to that of detergents. Through the method, the team intends to develop gels that can be applied in the nasal cavity.

The technologies are to be completed in 9 months-time.

India begins working on Genome Sequencing of COVID-19

The CCMB (Centre for Cellular and Molecular Biology), CSIR (Council of Scientific and Industrial Research) and IGIB (Institute of Genomics and Integrative Biology) are working on genome sequencing of COVID-19.

Highlights

The Genome Sequencing is being done to understand the evolution of the virus. This will help to learn about the future aspects. The blood samples of COVID-19 positive patients are to be collected and sent to the centres. The sequencing process requires large amount data. Currently, GoI is stepping into the phase of collection of data. It is expected that in another 3 to 4 weeks the researchers will isolate at least 200 to 300 strands.

The National Institute of Virology, that was first in the country to isolate the virus has been requested with to provide virus samples collected from different places.

About Genome Sequencing

The Genome Sequencing is used to determine complete DNA Sequence of an organism. The Genome Sequencing will also help to learn about family tree of the virus. The virus are classified based on their morphology, mode of replication, nucleic acid type, host organism and type of diseases caused by them.
