1. FLIP MUTATION (Syllabus: GS Paper 3 - Sci and Tech)

Context: Recently, researchers at the University of Tokyo revealed that the omicron subvariant JN.1, with a notable mutation in its spike protein known as L455S or "FLip" mutation, is poised to emerge as the predominant lineage of the SARS-CoV-2 virus globally.

Mutation

• About: A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
• Types of Chromosomal Mutations: Deletion, Duplication, Inversion, and Translocation.
• Causes: DNA replication errors, Exposure to mutagens, Errors during DNA repair, and Environmental factors.
• Examples: Sickle Cell Anemia, Melanism, and Antibiotic Resistance.

Flip Mutation

• About: This mutation occurs through binary crossover, where a randomly chosen bit within a chromosome is inverted.
• Referred to as "FLip" mutations: Such as L455S and L455F, they are named for their role in swapping the positions of amino acids F and L on the spike protein, thereby enhancing transmissibility.
• Example of the “FLip” Mutation: F456L, which was found in several XBB descendant strains developed this year, such as XBB.1.5.10, FE.1, and FD.1.1.

United Nations High Commissioner for Refugees (UNHCR)

• About: UNHCR is a worldwide organization committed to saving lives, protecting rights, and fostering a brighter future for refugees, forcibly displaced communities, and stateless individuals.
• Supportive Initiatives: UNHCR actively aids these populations in their voluntary repatriation, resettlement, or local integration efforts, promoting stability and well-being.
• Headquarters: Geneva, Switzerland,
• Legal Foundation: The 1951 Refugee Convention and its 1967 Protocol constitute the fundamental legal framework that underpins the mission and actions of UNHCR, guiding its efforts to address the needs of displaced and stateless individuals worldwide.

4. BOOSTING OF PULSE PRODUCTION (Syllabus: GS Paper 3 – Economy)

Conext: To ensure that farmers get remunerative prices and build up the buffer, the government will soon start procurement of tur dal which is currently ruling above the minimum support price (MSP) through a ‘dynamic pricing’ formula.

Boosting Domestic Pulse Production for Self-Reliance

• Signaling Increased Production: Allowing tur dal to be sold above the Minimum Support Price (MSP) acts as a signal to farmers, encouraging them to enhance production and consequently reducing the country's dependence on imports.
• Replication for Urad Dal:
• A similar procurement mechanism will be applied to urad dal, ensuring consistency in the effort to bolster domestic pulse production.
• Pulse Inflation Statistics: In November, inflation in the pulses category surged to 20.23%, up from 18.7% in October. Notably, arhar pulses experienced a substantial price increase of 42%.
• Tur Dal Imports: In the fiscal year 2022-23, India imported 0.9 million tonnes (MT) of tur dal. Notably, in the current fiscal (April-October), imports have already exceeded 0.45 MT.
• Major Imported Pulses: Tur, urad, and masoor (lentils), predominantly sourced from countries such as Mozambique, Malawi, Tanzania, Myanmar, Canada, and Australia.

.Minimum Support Price (MSP)

• About: MSP serves as a government-established rate at which crops are bought from farmers, providing them with protection against significant declines in agricultural prices.
• Announced by: The Commission for Agricultural Costs & Prices (CACP) recommends MSPs for 22 mandated crops and Fair and Remunerative Prices (FRP) for sugarcane.
• Origin of Concept: MSP was initially introduced in 1966, drawing inspiration from the Green Revolution.
• Crops covered: 7 types of cereals (paddy, wheat, maize, bajra, jowar, ragi and barley)

5. STAGFLATION (Syllabus: GS Paper 3 – Economy)

Context: Reserve Bank of India (RBI) officials believe the risk of stagflation — a portmanteau of economic stagnation with high inflation — has lowered further to 1% compared with 3% in August based on available data, using two approaches.

Stagflation

• About: Stagflation is a state characterized by a simultaneous increase in prices and stagnation of economic growth.
• Coined Term: The term "Stagflation" was introduced by Iain Macleod, a Conservative Party MP in the United Kingdom, in November 1965.
• Economic Situation Description: Stagflation is depicted as an economic scenario where the growth rate slows down, unemployment remains persistently high, and inflation or price levels remain elevated simultaneously.
• Economic Peril: Stagflation poses a significant threat to the economy.
• Economic Stimulus: In situations of typically low growth, central banks and governments often attempt to stimulate the economy through increased public spending and lower interest rates to boost demand.
• Challenge in Economic Tools: However, these measures, while aiming to spur growth, may also contribute to higher prices and inflation. Consequently, breaking out of the low growth-high inflation trap becomes challenging when inflation is already prevalent.
