• Economy: HCES 2023-24 data showed rural poverty at 7.2% and urban poverty at 4.6%, far below 2011-12 figures.
• Health: Guillain-Barré Syndrome (GBS) outbreak in Pune drew attention. GBS is an autoimmune nerve disorder.
• Polity: Article 224A of the Constitution allows ad hoc appointments of retired High Court judges to address case backlogs.
• History: Iron Age in India may be 1,000 years older than previously thought. Tamil Nadu site Sivagalai yielded tools dated to 3,345 BCE.
• Health: NHM (National Health Mission) achievements: MMR fell 83% since 1990, U5MR fell 75%.

The Household Consumption Expenditure Survey (HCES) 2023-24 data showed a dramatic reported decline in poverty.

• Rural poverty (HCES 2023-24): 7.2% of rural population.
• Urban poverty: 4.6%.
• Previous benchmark (2011-12): Rural 25.7%, urban 13.7%.
• MPI (NITI Aayog, 2022-23): Multidimensional Poverty Index showed 11.28% poverty, down from 29.17% in 2013-14.
• Tendulkar poverty line: Rs 33 per day (urban), Rs 27 per day (rural), per 2011-12 prices. Used for 2011-12 measurements.
• Rangarajan Committee (2014): Set a higher poverty line of Rs 47 (urban) and Rs 32 (rural), giving a higher poverty headcount of 29.5% in 2011-12.
• Key welfare schemes credited: MGNREGA, PM Awas Yojana, PMJDY (Jan Dhan), Swachh Bharat Mission, PMUY (Ujjwala), Poshan Abhiyan.

The dramatic decline must be read alongside debates about methodology. The HCES uses consumption expenditure as a proxy for welfare, not direct income measurement.

A review of NHM (National Health Mission) outcomes covered 2021-24.

• Vaccination: 220 crore vaccine doses administered.
• MMR (Maternal Mortality Ratio): Declined 83% since 1990. From 130 per lakh live births (2014-16) to 97 per lakh live births (2018-20).
• U5MR (Under-5 Mortality Rate): Reduced 75% since 1990. From 45 (2014) to 32 per 1,000 live births (2020).
• TB incidence: From 237 per 1,00,000 (2015) to 195 per 1,00,000 (2023). India's Nikshay Poshan Yojana provides nutritional support to TB patients.
• Ayushman Arogya Mandirs: 1.72 lakh centres operational; 1.34 lakh providing all 12 services.
• U-WIN Platform: A digital vaccination registry launched in 65 districts.
• NQAS certified: 7,998 health facilities certified under the National Quality Assurance Standards.

The Supreme Court approved ad hoc appointments of retired High Court judges to address criminal case backlogs.

• Constitutional basis: Article 224A of the Constitution.
• Appointment: The Chief Justice of a High Court can request a retired judge of that court (or another High Court) to sit and act as a judge, with the President's consent.
• Purpose: Address pendency of criminal cases. India's courts have over 5 crore pending cases.
• Tenure: Typically 2-3 years per appointment.
• Eligibility: Retired High Court judges who are willing and fit to serve.
• Distinction from regular appointments: Regular judges are appointed under Article 217. Ad hoc judges are a temporary measure for backlog clearance.

GS area: Ancient Indian History

New excavation data pushed India's Iron Age origins back by approximately 1,000 years.

• Sivagalai site (Tamil Nadu): Iron tools dated to 3,345 BCE. This would place India's Iron Age among the earliest in the world.
• Mayiladumparai (Tamil Nadu): 2,172 BCE.
• Brahmagiri (Karnataka): 2,140 BCE.
• Gachibowli (Telangana): 2,200 BCE.
• Global context: The conventionally accepted global Iron Age start is approximately 1,200 BCE. Hittite Empire use of iron: approximately 1,380 BCE.
• Textual reference: The Atharvaveda mentions iron (syama ayas) in the late Vedic period.
• Significance: If confirmed, these dates would fundamentally revise the history of metallurgy and suggest indigenous iron-working traditions in South India.

A cluster of GBS cases in Pune drew national attention in January 2025.

• What is GBS: An autoimmune condition where the immune system attacks the peripheral nervous system (nerves outside the brain and spinal cord).
• Suspected cases (Pune): 67 as of the report date.
• Common triggers: Campylobacter jejuni bacterial infection (contaminated food), Epstein-Barr Virus (EBV), Cytomegalovirus (CMV).
• Symptoms: Progressive muscle weakness, starting in feet and moving upward; tingling; in severe cases, paralysis requiring ventilator support.
• Treatment: Intravenous immunoglobulin (IVIG) or plasmapheresis (filtering antibodies from blood).
• Recovery: Most patients recover over weeks to months; some have long-term weakness.

• Deep Ocean Mission: Launched in 2021 by Ministry of Earth Sciences. The Matsya6000 submersible can reach 6,000 metres depth. The Varaha mining system operated at 5,270 metres depth. Focus: polymetallic nodules, rare metals.
• Differential pricing (CCPA): The Central Consumer Protection Authority (CCPA) issued notices to Ola and Uber for charging different prices based on whether the user has an Apple or Android phone. This raises consumer protection concerns under the Consumer Protection Act, 2019.
