Researchers from Taiwan developed a vaccine using DNA of coronavirus spike protein and tested its efficacy on Mice and Hamsters. This technique is different than mRNA vaccines.


What is DNA Vaccine?

DNA vaccine is thermally stable and no cold chain-needed in such vaccines. It can induce high levels of long-lasting neutralising antibody against SARS-CoV-2.  It can be produced quickly at lower cost. Several clinical trials have indicated the efficacy of DNA vaccines in treating infections like Zika, HIV-1, Ebola and influenza viruses.

What is mRNA-based vaccines?

Most of the available Covid-19 vaccines is based on mRNA strands. Such vaccines teach human immune system to recognize SARS-CoV-2 virus.

Similarity between both vaccines

Both DNA based and mRNA-based vaccines use genetic material encoding part of virus to draw out an immune response.

National Highways Authority of India (NHAI) issued guidelines for Toll centres to reduce waiting time to 10 seconds per vehicle at any point of time.

What is yellow line?

According to the guidelines, yellow lines at toll plazas will reduce the waiting queue of vehicles to 100 metres even during peak hours. If queue is beyond 100 metres, vehicles at the front will pass without paying toll.


NHAI highlights, it has successfully transitioned to 100 per cent cashless tolling from February 2021. Overall FASTag penetration has reached to 96 per cent to 99 per cent penetration. As the Electronic Toll Collection (ETC) penetration is increasing in India, NHAI is emphasising to have a new design and construct upcoming toll plazas based on traffic projections for next 10 years.

What is electronic toll collection?

It is a wireless system that automatically collect usage fee or toll charged to vehicles using toll roads, toll bridges, HOV lanes and toll tunnels. It is a faster alternative unlike toll booths, where vehicles stop and driver manually pays toll with cash or card.  FASTag is one such example.

About FASTag

This electronic toll collection system in India is operated by NHAI. It uses Radio Frequency Identification (RFID) technology to make toll payments directly from prepaid or savings account linked to it. The tag is affixed on windscreen of vehicle and enables to drive through toll plazas without stopping for transactions. State-run oil marketing companies like IOC, BPCL and HPCL signed MoUs in 2019 to enable use of FASTag to do purchases at petrol pumps.

Massachusetts Institute of Technology (MIT) has designed clothing which use special fibres to sense movement of person via touch.


Researchers from MIT also showed their clothes determined things such as if the person is sitting, walking, or doing any particular pose. Group from MIT’s Computer Science and Artificial Intelligence Lab (CSAIL) highlighted, their clothes can be used for athletic training and rehabilitation. These clothes can even help in monitoring health of residents in assisted-care facilities, with the permission of patients, and can determine things like- if the person has fallen or is unconscious.  

What researchers have developed?

Researchers have developed prototypes ranging from socks and gloves to a full vest. It uses a mix of more typical textile fibres and a small amount of custom-made functional fibers which can sense pressure from person wearing the cloth. Socks predict motion by examining different sequences of tactile footprints related to different poses when user transitions from one to another pose. Similarly, full-sized vest can determine wearers’ pose, activity and texture of contracted surfaces.

Significance of development

Unlike existing wearable electronics, smart cloth can be incorporated into traditional large-scale clothing production. These machine-knitted tactile textiles are soft, breathable, stretchable and can any forms.

Global Annual to Decadal 10-year Climate Update was released by United Kingdom’s Met Office led by World Meteorological Organisation.

Key Findings
