Context NASA has developed ExoMiner++, an AI tool to more accurately identify exoplanets by analysing space-telescope data, reducing false detections and speeding up planet discovery. Summary • ExoMiner++: A deep-learning AI model by NASA to detect and validate exoplanets.• Data used: Kepler and TESS missions.• How it works (Transit Method): When a planet passes in front of its star, it causes a small dip in brightness; ExoMiner++ analyses these light-curves.• Why important: Distinguishes true planets from false positives (binary stars, noise); more accurate and explainable than earlier models.• Achievements: Helped validate hundreds of exoplanets; identified ~7,000 candidates in TESS data. Key Terms • Exoplanet: A planet outside our solar system, orbiting another star.• TESS: Transiting Exoplanet Survey Satellite (NASA), scans nearby bright stars to find exoplanets using the transit method.
Right to Vote in India: Statutory Nature and Supreme Court Views
Right to Vote in India — Core Position • Right to vote is a statutory right, not a fundamental right.• It is created and regulated by the Representation of the People Act, 1951. Constitutional Link • Article 326: Provides the basis of elections (universal adult suffrage) but does not confer an individual fundamental right to vote.• Voting flows from statute; elections flow from the Constitution. Key Supreme Court Judgments • N.P. Ponnuswami (1952): Right to vote is purely statutory.• Jyoti Basu (1982): Voting is not a common law or fundamental right; it exists only by statute.• PUCL v.

GIG Economy
India’s gig economy has emerged as a powerful employment engine in an era of digital platforms and app-based services. However, behind the promise of flexibility and entrepreneurship lies a deep structural contradiction. The sector suffers from weak labour protection, income insecurity, and absence of enforceable rights, raising serious concerns about worker dignity and long-term sustainability. Legal Challenge: Worker or Contractor? Core Legal Tension Absence of Collective Voice Economic Reality: Long Hours, Unstable Income Flexibility vs Compulsion Income Volatility Social Impact: Insecurity and Human Cost Absence of Social Protection Unsafe and Stressful Work Environment Technology as Control: The Algorithmic Workplace Algorithm as Employer Lack of Due Process Key Demands Emerging from the Workforce Gig worker collectives have consistently raised the following demands: Government Response: Promise vs Practice Policy Intent Implementation Deficit Way Forward: Building a Fair Gig Framework To ensure inclusive growth of the gig economy, the following steps are critical: Conclusion India’s gig economy stands at a decisive moment. While it offers scale, innovation, and employment, ignoring its structural inequities risks institutionalising precarious labour. Sustainable digital growth requires moving beyond informal arrangements toward a rights-based framework that balances platform efficiency with worker security. Without timely intervention, the gig economy risks becoming a symbol not of opportunity, but of exclusion in the digital age.
Urban Co-operative Banks (UCBs)
Meaning Urban Co-operative Banks (UCBs) are co-operative credit institutions that primarily operate in urban and semi-urban areas, providing banking and credit facilities mainly to small borrowers, middle-income groups, MSMEs, traders, and salaried persons. They function on the principles of co-operation, mutual help, and democratic management, while also performing core banking activities like deposits and lending. Legal Framework UCBs are governed under a dual regulatory structure: Nature and Features Types of UCBs Functions Regulatory Reforms and Strengthening Recent reforms aim to improve governance, transparency, and stability: Capital and Prudential Norms Supervisory Mechanism Role in Financial System Challenges Way Forward Urban Co-operative Banks continue to be important grassroots banking institutions, especially for urban informal and semi-formal sectors, and ongoing reforms aim to make them safer, stronger, and more accountable.

Dollar-Based Settlement System
The dollar-based settlement system refers to the global practice of conducting international trade, financial transactions, and cross-border payments primarily in US dollars (USD). It is a core pillar of the post-Second World War international monetary order and underpins today’s global financial architecture. In a dollar-based settlement system: Historical Evolution Key Features Advantages of the Dollar-Based System Strategic Implications Challenges and Criticisms Emerging Alternatives and De-Dollarisation Efforts Despite these efforts, no alternative currency currently matches the dollar’s scale, liquidity, and trust. Conclusion The dollar-based settlement system remains the backbone of global finance due to historical momentum, institutional strength, and market confidence. While its dominance is increasingly questioned amid geopolitical shifts and de-risking strategies, any transition away from the dollar is likely to be gradual, fragmented, and partial, rather than abrupt. For the foreseeable future, the dollar will continue to play a central role in international economic relations.
Article 51 of the UN Charter – Right of Self-Defence
Text and Core Principle Article 51 of the UN Charter recognizes the inherent right of individual or collective self-defence if an armed attack occurs against a UN Member State, until the United Nations Security Council takes necessary measures to maintain international peace and security. This provision affirms that the UN Charter does not abolish the natural right of self-defence, but regulates its exercise within the collective security framework of the United Nations. Key Elements of Article 51 1. Inherent Right 2. Trigger: Armed Attack 3. Individual and Collective Self-Defence 4. Temporary Nature 5. Mandatory Reporting Conditions Governing Self-Defence (Customary Law) International law, particularly the Caroline Doctrine (1837), lays down three essential conditions: These principles continue to guide interpretation of Article 51. Judicial Interpretation and Case Laws Nicaragua v. United States (ICJ, 1986) Oil Platforms Case (Iran v. USA, 2003) Advisory Opinion on Wall in Occupied Palestinian Territory (2004) Article 51 and Non-State Actors Relationship with Article 2(4) Contemporary Relevance Conclusion Article 51 strikes a careful balance between state sovereignty and collective security. While it preserves the natural right of self-defence, it subjects that right to strict legal limits, oversight by the Security Council, and evolving norms of international law.
