15th Sep Current Affairs News Analysis | Prelims & Mains 2020



Recently, the inflation data for the month of August 2020 was released.

      WHY IN NEWS:

The inflation data includes retail inflation and wholesale inflation data.




  • The retail inflation is measured by the Consumer Price Index (CPI).
  • The wholesale price-based inflation is measured by Wholesale Price Index (WPI).


  • The retail inflation growth dipped to 6.69% in the month of August. It was at 6.73% in July 2020.
  • However, the retail inflation continued to grow beyond the Reserve Bank of India’s (RBI) upper margin of 6%.
  • The Central government has mandated the RBI to keep inflation within the range of 4±2%.
  • This inflation range (4% within a band of +/- 2%) was recommended by the committee headed by Urjit Patel in 2014.

The growth in retail inflation was primarily due to a rise in meat and fish prices that saw a 16.50% on-year rise in August.

  • The Consumer Food Price Index (CFPI) or the inflation in the food basket eased to 9.05% in the month of August. It was at 9.27% in July 2020.
  • The wholesale price-based inflation rose to 0.16% in August as food items and manufactured products turned costlier.
  • The WPI inflation was in the negative territory for four straight months — April (-) 1.57%, May (-) 3.37%, June (-) 1.81% and July (-) 0.58%.


  • Inflation is a quantitative measure of the rate at which the average price level of a basket of selected goods and services in an economy increases over some period of time.

It is the rise in the general level of prices where a unit of currency effectively buys less than it did in prior periods.

  • Often expressed as a percentage, inflation thus indicates a decrease in the purchasing power of a nation’s currency.
  • In India, inflation is primarily measured by two main indices — WPI (Wholesale Price Index) and CPI (Consumer Price Index) which measure wholesale and retail-level price changes, respectively.

      IASbhai WINDUP: 

  • Inflation in food articles during August stood at 3.84%.
  • However, fuel and power inflation fell 9.68% in August.

Graphene mask inactivates coronaviruses


New research: Graphene mask inactivates coronaviruses under sunlight

      WHY IN NEWS:

This is hot from IE

SYLLABUS COVERED: GS 3: Diseases : Science


Initial tests on two human coronavirus species showed the graphene inactivated over 90 per cent of the virus in five minutes and almost 100 per cent in 10 minutes under sunlight.

  • City University of Hong Kong Researchers have produced graphene masks with an anti-bacterial efficiency of 80 per cent.
  • They say can be raised to almost 100 per cent with exposure to sunlight for 10 minutes.


  • Most carbon-containing materials can be converted into graphene using a commercial CO2 infrared laser system.
  • Initial tests showed promising results in the deactivation of two coronavirus species.

Graphene is known for anti-bacterial properties.

  • The researchers created a laser-induced form of graphene and tested it on E coli.
  • It showed anti-bacterial efficiency of about 82 per cent.
  • Most of the E coli were dead after 8 hours.

      IASbhai WINDUP: 

The team also plans to test the graphene on the Covid-19 virus.
