  • FOIP combines Two Continents: Asia that is rapidly growing and Africa that possess huge potential of growth; and TwoOceans”: Free and open Pacific Ocean and Indian Ocean.

FOIP strategy consists of three pillars

  • Promotion and establishment of rule of law, freedom of navigation and free trade, etc.

Nobel Peace Prize

  • Two Journalists, Maria Ressa of Philippines and Dmitry Muratov of Russia, were awarded theNobel Peace Prize 2021 by the Norwegian Nobel Committee for their efforts to safeguard freedom of expression, which is a precondition for democracy and lasting peace.
  • Maria Ressa, co-founder of a digital media company Rappler, uses freedom of expression to expose abuse of power, use of violence and growing authoritarianism in her native country, thePhilippines.
  • Dmitry Muratov, co-founder of newspaper Novaya Gazeta, has been defending freedom of speech in Russia for decades under increasingly challenging conditions.


Decentralised Finance

  • Decentralised Finance (DeFi) is a system that allows financial products to appear on a public blockchain network which is not regulated by a central bank or intermediary.


  • It is built on blockchain applications that can used for remitting money or buying insurance or even borrowing money against cryptocurrencies.
  • Currently, very few platforms are offering these services but many Indian apps are exploring launching DeFi services industry trackers.
  • The first wave of DeFi innovation came in the form of Initial Coin Offerings (ICOs). These allowed companies to swap corporate entities and bank accounts for smart contracts and blockchain-based tokens, and raise millions in funding without any need for the gatekeepers of traditional finance.
  • Since then, the innovation hasn’t stopped. DeFi developers have been busy building an infrastructure for a whole new world of blockchain-based services:
  1. Decentralised exchanges such as Uniswap allow anyone to trade from anywhere with an internet connection. Anyone can swap assets directly with a smart contract, without needing a centralized exchange with an order book.
  2. Lending protocols like Aave and Compound are the blockchain-based equivalent of pawn shops. Users can stash their crypto in a smart contract and borrow against it without credit checks.
  3. DeFirobo-advisors such as Yearn act as decentralised financial advisors, automatically allocating digital assets across different DeFi protocols to earn the highest yield.



  • On May 22, 2012, a large meteor shower occurred near the town of Katol in Nagpur.
  • As it happened at noon, the villagers missed the light show but the shower caused sonic booms or thunder-like noises, initially spreading rumours that an aircraft had crashed.
  • The next day, researchers from the Geological Survey of India collected about 30 meteorite fragments with the largest weighing around a kilogram.
  • Initial studies revealed that the host rock was mainly composed of olivine, an olive-green mineral.
  • Olivine is the most abundant phase in our Earth’s upper mantle. Our Earth is composed of different layers including the outer crust, followed by the mantle and then the inner core. You can reach the upper mantle if you drill for about 410 kilometers.
  • Now, by studying the composition of these meteorite fragments, researchers have unravelled the composition expected to be present in the Earth’s lower mantle which is at about 660 km deep.
  • The paper published this month in PNAS reports the first natural occurrence of a mineral called bridgmanite. The mineral was named in 2014 after Prof. Percy W. Bridgman, recipient of the 1946 Nobel Prize in Physics.
  • Various computational and experimental studies have shown that about 80% of the Earth’s lower mantle is made up of bridgmanite. By studying this meteorite sample, scientists can decode how bridgmanite crystallized during the final stages of our Earth’s formation.

  • India football team captain Sunil Chhetri equalled the legendary Pele with his 77th international goal as his 83rd minute strike helped India beat Nepal 1-0 and saved his side from the verge of elimination in the SAFF Championships.
