A team of researchers from multiple institutions have successfully come up with a novel way of transforming an otherwise less-conducting organic material into an efficient conductor of electricity for electronic application. This paves the way for development of cost-effective, structurally and functionally amenable semiconductor devices, thus marking the dawn of a new era in semiconductor technology.
From Cat's-Whisker detectors in the early 1900s to electronic circuit chips in modern-day mobile phones, electronic devices have been modified in myriad.

2021 marks the 50th anniversary of the manufacture of the first digital computer in India
The year 2021 marks the 50th anniversary of the manufacture of the first digital computer in India. After being indigenously developed at the Bhabha Atomic Research Centre in 1969, the computer, TDC-12, was made by Electronics Corporation of India Ltd. (ECIL) in Hyderabad in 1971.
The efforts put in by ECIL in hardware and software development while bringing out a series of digital computers subsequently were phenomenal and laid the foundations for India’s computer industry.
Some states have raised the issue of vaccine shortages. Vaccine manufacturers are facing problems in procuring adjuvants from the US to further expand production capacity. The imposition of the Defence Production Act by the US can be one reason. Regardless, there has been no curtailment of supplies to states.
View: States are not facing a shortage of Covid vaccines, but there is a demand-supply mismatch
Wastage in India is witnessed primarily at the level of distribution. These are all operational management issues, and not intractable.
