The 2025 Nobel Prize in Physics was awarded to John Clarke, Michel Devoret, and John Martinis for their groundbreaking work on macroscopic quantum tunnelling. Their experiments in the 1980s proved that quantum mechanical laws, usually associated with subatomic particles, could govern entire electrical circuits visible to the naked eye. By using Josephson junctions and superconductors, they demonstrated that current could 'tunnel' through barriers even at zero voltage. This discovery laid the foundation for modern quantum computing, specifically the development of superconducting qubits, and advanced our understanding of quantum states in larger systems.
The laureates proved that electrical circuits can obey quantum mechanical laws rather than just classical physics.
They used Josephson junctions to observe tunnelling and energy quantisation in superconducting circuits.
Their findings are fundamental to the operation of superconducting qubits used in today's quantum computers.
Exam Points
Laureates: John Clarke (UC Berkeley), Michel Devoret (Yale), and John Martinis (UC Santa Barbara).
Prize amount: 11 million Swedish kroner (approx. ₹1 crore).

The detention of climate activist Sonam Wangchuk and other peaceful protesters from Ladakh under the National Security Act (NSA) has sparked significant debate. Wangchuk was leading a march to Delhi demanding statehood and Sixth Schedule status for Ladakh. The editorial argues that using the NSA, a law intended for threats to national security and public order, against peaceful dissenters is a misuse of power. It emphasizes that the Supreme Court distinguishes between 'law and order' issues and 'public order' threats. The government is urged to engage in meaningful dialogue rather than using preventive detention to stifle legitimate democratic aspirations.
Sonam Wangchuk was detained while advocating for Ladakh's inclusion in the Sixth Schedule and statehood.
The National Security Act (NSA) is meant to address acts that disturb the 'even tempo of the life of the community'.
The Supreme Court has clarified that a clear distinction must be made between 'law and order' and 'public order'.
Exam Points
Relevant Law: National Security Act (NSA).
Constitutional Provision: Sixth Schedule of the Indian Constitution.
Despite achieving significant tactical victories against Hamas and Hezbollah, Israel remains caught in a 'strategic labyrinth'. The conflict, which escalated after the October 7 attacks, has seen Israel dismantle much of Hamas's military infrastructure and eliminate key leaders. However, the broader goal of regional stability remains elusive. The Abraham Accords and the proposed India-Middle East-Europe Economic Corridor (IMEEC) are under threat as Arab nations reassess their security ties. The article suggests that without a political solution to the Palestinian issue, Israel's military gains may not translate into long-term security, as regional players like Iran continue to pose challenges.
Israel has achieved tactical success by degrading Hamas and Hezbollah's capabilities but lacks a clear 'end plan' for Gaza.
The conflict has stalled regional integration projects like the Abraham Accords and the IMEEC.
Saudi Arabia and other Gulf monarchies are diversifying their security partnerships due to perceived shifts in U.S. regional commitment.
India holds approximately 25,000 tonnes of gold in private hands, valued at $2.4 trillion, yet remains a major importer, contributing significantly to the trade deficit. The article advocates for a revitalized, trust-based gold monetisation scheme to unlock this 'under-the-pillow' wealth. By creating a transparent ecosystem with hallmarking centers and digital gold accounts, the government can mobilize domestic capital for infrastructure and innovation. This shift would reduce reliance on volatile foreign investment and external debt. Transforming gold from a passive asset into a productive economic tool is seen as essential for India's journey toward 'Atmanirbharta' (self-reliance).
Indian households hold nearly $2.4 trillion worth of gold, which is larger than the total credit extended by Indian banks.
Gold imports account for roughly 8% of India's total import bill, creating a persistent trade deficit.
A successful gold monetisation scheme requires infrastructure for trusted valuation, seamless logistics, and tax-free incentives for depositors.
Exam Points
Estimated private gold holdings: 25,000 tonnes.
Value of holdings: ~$2.4 trillion.
Gold's share in India's trade deficit (2010-2013): Almost one-third.
Recent changes in U.S. immigration policies, including a proposed $100,000 visa fee for new H-1B workers, are creating hurdles for international STEM talent, particularly from India. Data shows that while the U.S. IT sector has grown significantly, the growth of home-grown STEM talent has not kept pace with demand. Non-residents earn a disproportionately high number of STEM Master’s and Doctoral degrees in the U.S. As the U.S. tightens its borders, countries like China, the U.K., and Germany are actively vying for this talent. This shift could potentially lead to a 'brain drain' from the U.S., impacting its long-term technological edge.
The U.S. relies heavily on foreign-born talent, with non-residents earning 55% of STEM Master’s degrees in 2020-21.
Proposed high visa fees and restrictive policies may push skilled Indian professionals to look for opportunities in other countries.
Computer and mathematical occupations in the U.S. grew by 40% between 2016 and 2024, far outstripping domestic talent supply.
Exam Points
Proposed H-1B fee: $100,000.
Non-resident share of U.S. STEM Master's degrees: 55%.
Growth in U.S. computer/math jobs (2016-2024): 40%.
Despite the Union Health Ministry's efforts to upgrade pharmaceutical standards, no Indian state has fully complied with the Corrective and Preventive Action (CAPA) guidelines. These guidelines are a crucial part of the revised Schedule M of the Drugs and Cosmetics Rules, aimed at ensuring global quality standards. While 18 states have adopted the Online National Drugs Licensing System (ONDLS), the implementation of CAPA remains voluntary and slow. This lack of compliance is concerning given recent international incidents involving adulterated Indian-made cough syrups. The Ministry emphasizes that CAPA is essential for systematic investigation and resolution of manufacturing defects.
The revised Schedule M is a critical update to India’s pharmaceutical manufacturing regulations to ensure safety and quality.
CAPA (Corrective and Preventive Action) is a universal quality management methodology for process improvement in the pharma industry.
The ONDLS is a single-window digital platform developed by CDAC and CDSCO for transparent drug licensing across India.
Exam Points
Regulatory Framework: Revised Schedule M of Drugs and Cosmetics Rules.
Digital Platform: Online National Drugs Licensing System (ONDLS).

The World Bank has upgraded India's GDP growth outlook for the financial year 2025-26 to 6.5%, up from its previous estimate of 6.3%. This upgrade is attributed to resilient domestic conditions, strong private consumption, and the positive impact of GST reforms. However, the forecast for 2026-27 has been slightly lowered to 6.3% due to potential headwinds from U.S. tariffs on Indian exports. Despite global uncertainties, India is expected to remain the world's fastest-growing major economy. The report also noted that rural wage growth and agricultural output have performed better than expected.
India's real GDP growth reached 7.8% in the April-June 2025 quarter, exceeding initial expectations.
The World Bank credits GST reforms, including simplified compliance and reduced tax brackets, for supporting economic activity.
Potential U.S. tariffs (up to 50%) on three-quarters of India's goods exports are a significant risk factor for future growth.
Exam Points
FY26 Growth Forecast: 6.5%.
April-June 2025 Quarter Growth: 7.8%.
Potential U.S. Tariff Impact: 50% on ~75% of exports.
As the global economy enters a period of uncertainty due to trade fluctuations and tariffs, the article emphasizes the need for Indian private capital to invest domestically. Despite record profits, private investment has not kept pace, with many firms looking toward foreign markets. The author argues that relying on external demand is risky and that the focus should shift to stimulating domestic demand and enhancing internal productivity. Furthermore, India's gross expenditure on R&D remains low at 0.64% of GDP, mostly funded by the government. A shift toward private sector-led innovation is crucial for long-term economic resilience.
Private capital expenditure in India has remained sluggish despite high corporate profits and government incentives like PLI schemes.
India's R&D spending is significantly lower than global peers (e.g., China at 2.1% of GDP), with the private sector contributing very little.
The current global environment of 'de-globalisation' makes it imperative for Indian capital to unlock domestic wealth for local growth.
Exam Points
India's R&D expenditure: 0.64% of GDP.
China's R&D expenditure: 2.1% of GDP.
CAGR of India's outward FDI: 12.6%.
