Content : Ladakh gets new policies on quota, domicile status IISc researchers develop artificial metal-based nanozyme that prevents excess blood clotting A ban, a split verdict, and a health concern Does the civil services examination need reform? No contempt if Parliament or legislatures make laws: SC ‘Sulphur-cleaning device in coal plants not necessary’ EC introduces new tech-driven system to update voter turnout Bacteria found at Rajgir hot spring lake shows antimicrobial activity Ladakh gets new policies on quota, domicile status Context & Background Ladakh became a Union Territory (UT) after the abrogation of Article 370 in August 2019. Local civil society groups have long demanded constitutional safeguards for Ladakh’s culture, demography, land, and jobs (similar to Article 371 or Sixth Schedule protections). The Centre has now introduced several key policy reforms in response. Relevance : GS 2(Federalism , Governance) Reservation Policy Changes Total Reservation Cap Raised: Earlier: Capped at 50% (as per 2004 J&K Reservation Act). Now: Raised to 85%, excluding EWS quota. With 10% for EWS, the total reservation hits 95%, among the highest in India. Scheduled Tribes Focus: 80% of jobs likely to be reserved for STs, reflecting Ladakh’s majority tribal population. Comparison: Meghalaya: 85% for SCs/STs. Arunachal Pradesh: 80% for STs. Domicile Policy To qualify as a domicile: One must have resided in Ladakh continuously for 15 years since October 31, 2019 (UT foundation day). Applies even to children of Central government officials. Implication: Tightens eligibility for government jobs and other benefits. Aimed at preserving Ladakhi identity and limiting demographic changes. Language Policy Official languages of Ladakh now include: English, Hindi, Urdu, Bhoti, and Purgi. Bhoti and Purgi are local languages, reflecting the cultural and linguistic diversity of the region. Changes in Hill Council Composition One-third reservation for women in hill councils (LAHDC Leh and Kargil). To be implemented on a rotational basis. Boosts women’s political representation in Ladakh’s local governance. Broader Significance Responds to the socio-political concerns of Ladakhi stakeholders. Enhances affirmative action, local autonomy, and cultural preservation. Indicates Centre’s decentralized approach to governance in tribal-majority UTs. Could serve as a model for region-specific governance policies elsewhere in India. IISc researchers develop artificial metal-based nanozyme that prevents excess blood clotting Research Context & Objective Conducted by: IISc researchers, led by Prof. G. Mugesh (Dept. of Inorganic and Physical Chemistry). Objective: To prevent abnormal blood clotting (thrombosis) linked to conditions like pulmonary thromboembolism (PTE) and COVID-19. Relevance : GS 2(Health) ,GS 3(Technology) Understanding the Problem Normal Blood Clotting (Haemostasis): Triggered by injury to blood vessels. Platelets cluster to form a clot, activated by agonists like collagen and thrombin. Abnormal Clotting (e.g., in PTE, COVID-19): Caused by oxidative stress and excess Reactive Oxygen Species (ROS). ROS leads to over-activation of platelets, forming harmful clots (thrombosis). Thrombosis contributes to ischemic events, strokes, and deaths. Nanozyme Development Developed: Redox-active nanomaterials mimicking natural antioxidant enzymes. Function: Scavenge ROS to regulate oxidative stress and prevent platelet over-activation. Synthesis: Achieved via controlled chemical reactions using small molecular building blocks. Key Findings Tested different sizes, shapes, and morphologies of nanozymes. Platelets were isolated and activated using physiological agonists in lab settings. Spherical-shaped Vanadium Pentoxide (V₂O₅) nanozymes showed the highest efficacy in preventing excess aggregation. Medical Significance Potential to treat or prevent: Pulmonary Thromboembolism (PTE) Thrombosis linked to COVID-19 Ischemic stroke (next phase of research) Offers an alternative to conventional anticoagulants with a more targeted approach via ROS modulation. Wider Implications Represents a biomimetic therapeutic approach — using synthetic materials to mimic natural enzyme functions. Opens avenues in nanomedicine for targeted, controlled therapies. Can reduce side-effects typically associated with broad-spectrum blood thinners. A ban, a split verdict, and a health concern Mustard Oil in India: Context Third-most consumed edible oil in India. Extracted from Indian mustard crop, high in erucic acid (40–54%). Health concerns exist due to high erucic acid, especially in Western countries. Relevance : GS 2(Governance) ,GS 3(Agriculture) Two Major Policy/Judicial Decisions FSSAI Ban (2021): Banned blending of mustard oil with other edible oils. Aim: To prevent adulteration and boost domestic mustard production. Blending allowed under law up to 20% but was misused (industry blends up to 50%). Supreme Court Verdict (2024): Struck down approval of GM mustard (DMH-11). Reason: Insufficient health impact assessment. Split verdict; health safety concerns cited by one of the judges. Health Concern: Erucic Acid Present in high quantity in Indian mustard oil (40–54%). International limit: Less than 5% (U.S., Canada, Europe). Animal studies: High erucic acid linked to heart issues, liver and kidney damage. Human impact: No conclusive evidence, but stigma and strict regulations abroad. Alternative abroad: Canola oil (developed in Canada) with <2% erucic acid. GM Mustard (DMH-11): Prospects and Benefits Lower erucic acid content (30–35% vs 40–54%). Higher yield potential. Reduces need for blending and dependency on imported edible oils. India’s edible oil import bill: $20.56 billion (NITI Aayog). Scientific achievement: Comparable to Western low-erucic cultivars. Needs further R&D to bring levels below 5%. Blended Mustard Oil: Pros and Cons Advantages: Dilutes erucic acid content. Rich in unsaturated fats → improves cholesterol profile (↑ HDL, ↓ LDL). Practical in absence of low-erucic domestic cultivars. Concerns: Rampant adulteration (FSSAI 2020 survey: 24.21% samples failed quality checks). Mustard oil had highest adulteration rates. Artificial flavors and toxic substances used. Policy Recommendations Allow blended mustard oil sales in packaged and branded form with clear labelling. Enforce blending limits (currently often breached). Strengthen State-level food safety mechanisms (health is a State subject). Prioritize development of low-erucic GM mustard varieties with <5% content. Take a holistic view — blend health, economic, and scientific perspectives in policymaking. Does the civil services examination need reform? Historical Background The structure of the civil services exam is rooted in the Macaulay Report of 1854 which emphasized merit-based selection. The Kothari Committee (1975) formalized the three-tier structure: Prelims, Mains, and Interview. Relevance : GS 2(Education ) Evolution of Preliminary Exam Earlier format: Optional subject + General Studies with a 2:1 weightage. Results were opaque; only names of qualifiers were published—no marks or cut-offs were revealed. This ‘black box’ model limited aspirants’ ability to question results. Transparency and Reform Pressure Post-RTI Act (2005): UPSC had to disclose evaluation methods. Growing scrutiny led to formation of the S.K. Khanna Committee (2010). Major reform (2011): Optional paper removed. Prelims restructured to: Paper I: GS Paper II: CSAT (aptitude, reasoning, English) Issues with CSAT (Paper-II) Originally, CSAT marks were counted, favoring urban, English-medium, science/engineering students. This triggered protests, particularly from rural/Humanities background aspirants. Change made: CSAT became a qualifying paper (33% minimum), marks not counted for merit. Main Exam Concerns Restructured in 2013 after Nigvekar Committee recommendations. GS papers now cover wide topics: polity, governance, economy, etc. Current issues: Short-answer focus (20 questions) encourages rote memorization over analysis. No long-form questions that test deep analytical or problem-solving abilities. Optional subject choices driven by scoring trends, not academic background—misaligns intent. Prelims as a ‘Gatekeeper’ Prelims now functions more as a screening tool, cutting ~5 lakh applicants to ~10,000. Paper-I (GS) is highly unpredictable, making preparation uncertain. Paper-II still favors science/engineering students, even though it’s qualifying. Opportunity cost is high for serious aspirants investing years into uncertain outcomes. Suggested Reforms Re-evaluate the role of Prelims: Ensure it tests potential, not just elimination. Revamp GS Mains papers: Include long-form analytical questions. Replace the optional subject with two papers on governance and public policy to ensure relevance. Improve alignment between the exam structure and the qualities expected in civil servants. Conclusion The current system, though evolved, still reflects structural distortions. A comprehensive reform is needed to: Reduce unfair filtering, Promote diversity, Encourage analytical thinking over rote learning, And better align aspirants’ capabilities with administrative roles. No contempt if Parliament or legislatures make laws: SC Background of the Case Petitioners: Nandini Sundar (sociologist) and others filed a contempt petition (2012). Target: Chhattisgarh government’s alleged non-compliance with the SC’s 2011 order. The SC in 2011 had directed the State to disband vigilante groups (like Salwa Judum) and stop arming tribals as Special Police Officers (SPOs). Relevance : GS 2(Polity , Judiciary) Petitioners’ Allegations The State bypassed the SC’s directions by: Enacting Chhattisgarh Auxiliary Armed Police Force Act, 2011 — legalising SPOs. Not vacating schools/ashrams occupied by security forces. Failing to compensate victims affected by Salwa Judum and SPO actions. Supreme Court’s Ruling (May 15, 2024) Law made by legislature ≠ contempt of court. Legislatures have plenary powers to make laws. Unless a law is declared unconstitutional, it remains valid and cannot be equated with defiance of court orders. Contempt plea dismissed. Key Judicial Observations Balance of powers must be maintained between judiciary and legislature. A law passed post-court order is not contempt unless: It directly disobeys the order. It is declared ultra vires the Constitution. Remedy against an unconstitutional law lies in challenging it in a constitutional court, not through contempt proceedings. Broader Concerns & Directions Recognised the prolonged unrest in Chhattisgarh due to Maoist violence. Urged specificpeace and rehabilitation measures by: State government Union government Cited Article 315: Responsibility lies with both governments to ensure law and order and welfare of residents. Legal and Constitutional Significance Reiterates legislative supremacy in its domain unless judicially struck down. Clarifies that legislative action isn’t inherently contemptuous of earlier court orders. Strengthens separation of powers and checks and balances in governance. ‘Sulphur-cleaning device in coal plants not necessary’ Context FGD (Flue Gas Desulphurisation) units are used to reduce sulphur dioxide (SO₂) emissions from coal-fired thermal power plants (TPPs). These were made mandatory in 2015 as part of stricter environmental norms. Despite repeated extensions, 92% of India’s 600 units still haven’t installed FGDs. Relevance : GS 3(Environment an dEcology) Committee Recommendation High-powered expert committee chaired by PSA Ajay Sood recommends FGDs are unnecessary for 80% of plants. Suggests FGDs be mandatory only in Category A plants: Within 10 km of NCR and cities with 1 million+ population. Out of 66 such plants, only 14 have FGDs installed. Scientific Rationale Behind the Recommendation Ambient SO₂ levels across India are between 10–20 µg/m³, well below the national standard of 80 µg/m³. Indian coal is naturally low in sulphur content. Cities with FGDs and without FGDs show negligible difference in ambient SO₂ levels. SO₂ levels in general do not exceed permissible limits, hence do not justify nationwide FGD installation. Operational & Economic Considerations High capital costs and few vendors for FGD installation. Potential rise in electricity tariffs if cost passed to consumers. COVID-19 disruptions cited as a reason for delays in FGD compliance. Historical deadline extensions by the Ministry of Power due to implementation hurdles. Environmental Compliance Committee clarifies: TPPs must still meet standards for: Particulate Matter (PM) emissions. Freshwater consumption. SO₂ stack emission limits can be relaxed, as long as National Ambient Air Quality (NAAQ) standards are met. NAAQ standards, not stack norms, are the primary metric for protecting public health. Institutions Involved Reports considered from: CSIR-NEERI National Institute of Advanced Studies IIT Delhi All supported the view that FGDs are not essential across all plants. Policy Implications Marks a major reversal of India’s 2015 emission control policy. Likely cost savings for power producers, but raises concerns over long-term air quality safeguards. Reflects a shift towards region-specific environmental regulation rather than blanket norms. EC introduces new tech-driven system to update voter turnout Context The Election Commission (EC) has introduced a technology-based system to provide real-time updates on voter turnout. Comes amid opposition concerns over alleged discrepancies and delays in previous turnout data reporting. To be implemented before the Bihar Assembly elections later this year. Relevance : GS 2(Elections , Reforms) Key Features of the New System Presiding officers at each polling station will directly enter turnout data every two hours into the ECINET app. Data is automatically aggregated at the constituency level. Reduces dependence on manual reporting via calls, SMS, or WhatsApp. Improvements Over Previous Method Earlier method involved: Manual recording by sector officers. Delays of 4–5 hours, with some updates arriving next day. New system aims for: Near real-time updates every two hours. Final turnout data entered at polling station itself before presiding officers leave. Tech Implementation Uses the ECINET app for data entry. Becomes a core part of ECINET infrastructure. The Voter Turnout App will reflect constituency-wise data updates. Offline mode available; data syncs once network is restored. Advantages Faster transparency, reducing data discrepancy allegations. Greater accountability of presiding officers at the booth level. Enhances public trust in the polling process. Reduces manual errors and communication lags. Challenges & Conditions Network connectivity in rural or remote polling booths may delay real-time data. Continued need for training of polling staff in app usage. Approximate data still subject to minor post-poll adjustments. Broader Implications Reinforces EC’s commitment to transparent, tech-driven elections. Reflects the increasing role of digital infrastructure in electoral processes. Sets precedent for future state and national elections. Bacteria found at Rajgir hot spring lake shows antimicrobial activity Scientific Background & Relevance Thermophiles are bacteria that thrive in high temperatures (45–70°C), intolerable for most life forms. Hot environments like hot springs, deep-sea vents, compost piles are rich in minerals but have fewer life competitors. Thermophiles often produce potent antibiotics to outcompete other organisms in these harsh niches. Relevance : GS 3(Environment and Ecology) Study at Rajgir Hot Spring Lake (Nalanda, Bihar) Conducted by Vellore Institute of Technology (VIT), Tamil Nadu. Marked as one of India’s first microbiological investigations into the Rajgir hot spring. Temperature of water and soil samples ranged between 43–45°C. Key Findings Used 16S rRNA metagenomics to analyze microbial diversity. Found Actinobacteria dominated (40–43%) of the microbial population. Significant since most hot springs globally have <20% Actinobacteria. Known for producing important antibiotics (e.g., streptomycin, tetracycline). Antibacterial Potential Isolated seven strains of Actinobacteria that showed potent antibacterial activity. Tested against pathogens like E. coli, Salmonella, Klebsiella, Pseudomonas, Staphylococcus. Identified antibacterial activity by observing growth inhibition on culture plates. Discovery of New Antimicrobial Compound Diethyl phthalate extracted using Gas Chromatography-Mass Spectrometry (GC-MS). Sourced from Actinomycetales bacterium spp. Effective against Listeria monocytogenes, a deadly foodborne pathogen causing listeriosis. Broader Implications Urgent need for new antibiotics due to rising antimicrobial resistance (AMR). WHO projects $1 trillion global healthcare cost by 2050 due to AMR. Discovery at Rajgir highlights the untapped potential of Indian hot springs in antibiotic research. Industrial & Agricultural Applications Thermophiles also produce enzymes and compounds useful in: PCR testing (e.g., enzyme from Thermus aquaticus used in COVID testing). Agriculture: e.g., Leh hot springs’ bacteria shown to promote plant growth. Challenges & Gaps Indian hot springs are still understudied despite their potential. Field sampling in extreme temperatures is logistically difficult. Identifying active compounds from a microbial pool remains a time-intensive process.
