  • Optical Computing and AI with Light

    Why in the News?

    Finnish researchers showed that nonlinear optical fibres can perform AI tasks efficiently, advancing optical computing.

    About Optical Computing:

    • Overview: A computer that uses light (photons) instead of electricity (electrons) to process data.
    • Why Important: Light is faster, makes less heat, and carries more data at once.
    • Technology Used: Runs through optical fibres, the same cables that carry internet data.
    • Main Challenge: Hard to control how light behaves, especially when it gets very strong and non-linear (changes colour, merges, or spreads).

    Recent Breakthrough:

    • Research:
      • Turned images into light pulses.
      • Sent them through optical fibre where the light changed.
      • These changes acted like a hidden computing layer.
      • The system read the light at the other end to classify the images.
    • Results: Reached 91–93% accuracy, close to normal AI computers.

    How can it help AI working?

    • Energy-efficient AI hardware: Can make faster and greener AI systems in the future.
    • Tech needs: New tools like photonic chips and optical neural networks before large-scale use.

    About Typhoon & Super Typhoon:

    • Typhoon: A tropical cyclone forming in the Western Pacific Ocean and China Sea, usually above sea temperatures of 27°C.
    • Formation: Warm, moist air rises and creates a low-pressure system with spiralling winds.
    • Super Typhoon: Defined by the US Joint Typhoon Warning Center (JTWC) as sustained winds of ≥240 km/h (some agencies use 185 km/h).
    • Structure:
      • Eye: Calm centre.
      • Eyewall:  Strongest winds and rainfall.
      • Spiral Rainbands: Bands of showers spreading outward.
    • Impacts: Can cause storm surges, coastal flooding, landslides, and destruction of infrastructure, agriculture, and homes.

    Back2Basics: Tropical Cyclones

    • What is it: Large low-pressure systems over warm oceans, marked by rotating winds, heavy rain, and storm surges.
    • Conditions: Form when ocean temps >27°C, with moist rising air releasing latent heat to fuel convection.
    • Rotation: Driven by the Coriolis force – anticlockwise in Northern Hemisphere, clockwise in Southern.
    • Structure: Eye (calm), Eyewall (violent winds/rains), Rainbands (widespread showers).
    • Regional Names: Typhoons (Pacific), Hurricanes (Atlantic/Caribbean), Cyclones (Indian Ocean).
    • Drivers & Frequency: Common in Southeast Asia due to warm Pacific waters, El Niño/La Niña cycles, and climate change.
    • Impacts: Loss of life, property damage, flooding, soil salinisation, displacement, and disease outbreaks.
    • Climate Change Link: Global warming is making tropical cyclones stronger, less predictable, and more frequent, raising risks for coastal populations.

    1. Jet streams occur in the Northern Hemisphere only.

    2. Only some cyclones develop an eye.

    3. The temperature inside the eye of a cyclone is nearly 10°C lesser than that of the surroundings.

    Which of the statements given above is/are correct?

    Options: (a) 1 only (b) 2 and 3 only (c) 2 only * (d) 1 and 3 only

     

  • Earth gains new tiny ‘Quasi-Moon’ 2025 PN7

    Earth gains new tiny 'Quasi-Moon' 2025 PN7

    Why in the News?

    Astronomers have confirmed the discovery of asteroid 2025 PN7, Earth’s latest quasi-moon.

    About Quasi-Moon 2025 PN7:

    • Discovery: First detected on 2 August 2025 by the Pan-STARRS 1 telescope in Hawaii; confirmed in September 2025 as Earth’s newest quasi-satellite.
    • Orbit: Circles the Sun, not Earth, but remains near Earth due to a 1:1 orbital resonance – meaning it completes one solar orbit in the same time as Earth.
    • Distance from Earth: At closest, ~299,000 km, similar to the Moon’s distance.
    • Physical Traits: Roughly 19 metres wide, very faint (magnitude 26.4), requiring large telescopes to track.
    • Orbital Parameters: Semi-major axis 1.003 AU (same as Earth), eccentricity 0.108 (slightly oval), inclination just under .
    • Arjuna Nature: Fits the Arjuna asteroid class criteria – extremely Earth-like orbit, low eccentricity, and low inclination, making it appear as a temporary companion.
    • Stability: Expected to remain a quasi-satellite for ~128 years before shifting into another orbital configuration.

    What is the Arjuna Asteroid Class?

    • Overview: A rare group of near-Earth objects (NEOs) with orbits closely matching Earth’s path around the Sun.
    • Etymology: Originated with the discovery of asteroid 1991 VG by astronomer Robert H. McNaught at the Siding Spring Observatory in Australia in 1991.
    • Name Origin: Inspired by Arjuna from the Mahabharata – symbolising fast-moving and elusive objects.
    • Special Traits:
      • Can approach Earth more closely than most asteroid families.
      • Sometimes become temporary mini-moons or quasi-satellites.
      • Have relatively low relative velocities, making them attractive for spacecraft missions.
    • Scientific Importance:
      • Offer natural laboratories for studying orbital resonance and gravitational effects.
      • Useful for testing asteroid mining and redirection technologies.
      • Significant for planetary defence, since tracking their movements refines collision risk predictions.

  • [22nd September 2025] The Hindu Op-ed: Uranium unrest: On uranium mining in Meghalaya

    PYQ Relevance

    [UPSC 2018] Policy contradictions among various competing sectors and stakeholders have resulted in inadequate ‘protection and prevention of degradation’ to the environment. Comment with relevant illustration

    Linkage: The uranium mining push in Meghalaya illustrates a clear policy contradiction, India’s strategic and energy security imperatives versus constitutional safeguards for Scheduled/Tribal Areas and environmental sustainability. The Centre’s OM exempting uranium from public consultation shows how national security priorities often override local consent and ecological concerns, leading to inadequate protection. Thus, it serves as a live illustration of competing sectoral interests producing environmental degradation risks.

    Mentor’s Comment

    India’s renewed push for uranium mining in Meghalaya, despite strong tribal opposition, has reopened debates on resource governance, environmental justice, and constitutional safeguards. For UPSC aspirants, this case is not only about Meghalaya but about how India manages its uranium reserves, balances national security with sustainability, and navigates the tensions between state imperatives and community consent. This article integrates the editorial’s concerns with a broader analysis of uranium mining in India and its implications.

    Introduction

    The Union Environment Ministry’s office memorandum (OM) exempting uranium and other strategic minerals from public consultation has intensified unrest in Meghalaya. Tribal Khasi groups, opposing uranium extraction since the 1980s, see this as a denial of their constitutional and cultural rights. At the same time, India’s nuclear ambitions make uranium strategically vital. This tension between energy security and indigenous consent places India at a crucial crossroads of democratic governance and resource management.

    Why is this in the news?

    The Centre’s attempt to mine uranium in Meghalaya, against the backdrop of decades-long opposition, is a landmark moment in India’s mineral politics. For the first time, an executive order (OM) has bypassed community consultations for uranium mining. Given the toxic environmental footprint of uranium mining and its irreversible impact on tribal lands, the issue has become both a governance crisis and an ecological flashpoint.

    What is the history of uranium mining resistance in Meghalaya?

    1. Khasi opposition since the 1980s: Resistance in Domiasiat and Wahkaji has endured for four decades.
    2. Distrust from Jharkhand experience: Singhbhum mines faced protests due to radiation exposure and livelihood loss.
    3. Procedural unfairness: Hearings often conducted in unfamiliar languages, ignoring objections.

    Why is the new Office Memorandum controversial?

    1. Exempts strategic mineral mining from public consultation, silencing affected communities.
    2. Issued without parliamentary scrutiny, showing executive overreach.
    3. Weakens constitutional safeguards, turning stewards of the land into bystanders in decisions affecting their survival.

    What constitutional and legal protections are at stake?

    1. Sixth Schedule: Khasi Hills Autonomous District Council may invoke its autonomy.
    2. Judicial precedents: Niyamgiri (2013) recognized the primacy of tribal consent.
    3. Fifth and Sixth Schedules: Provide a strong legal basis for resistance.
    4. Global principle of FPIC (Free, Prior, and Informed Consent): Ignored in this decision.

    Why is uranium mining a risky proposition?

    1. Environmental hazards: Radioactive waste and contamination of water sources.
    2. Human health risks: Increased cases of radiation-linked illnesses reported in Singhbhum.
    3. Cultural disruption: Tribal communities lose ancestral land and cultural heritage.
    4. Short-term security vs long-term sustainability: Overemphasis on uranium undermines renewable energy pathways.

    Uranium Mining in India – An Overview

    Where is uranium mined in India?

    1. Jharkhand (Singhbhum district): Oldest uranium mines; key hub of Uranium Corporation of India Limited (UCIL).
    2. Andhra Pradesh (Tummalapalle, Kadapa district): Estimated to be one of the world’s largest uranium reserves (~150,000 tonnes).
    3. Telangana (Nalgonda district): Lambapur-Peddagattu reserves.
    4. Meghalaya (Domiasiat, Wahkaji): Rich reserves but stalled due to tribal opposition.
    5. Rajasthan (Rohil in Sikar district): Exploratory work underway.

    What are the requirements and process of uranium mining?

    1. Requirement of Environmental Clearances: Normally includes public consultation, impact assessments, and Forest Rights Act compliance (bypassed in the new OM).
    2. Mining process:
      • Open-cast mining: Surface excavation, highly polluting.
      • Underground mining: Safer but expensive.
      • Processing: Crushing ore, followed by leaching (acid/alkaline) to extract uranium oxide (yellowcake).
      • Radiation management: Requires robust safeguards in waste disposal, tailing ponds, and worker protection—areas where India has faced criticism.

    India’s standing in global uranium context

    1. Global reserves: Australia, Kazakhstan, Canada, Russia dominate.
    2. India’s share: About 1-2% of world reserves, modest compared to global leaders.
    3. Import dependence: Despite domestic efforts, India imports uranium from Kazakhstan, Russia, Uzbekistan, Canada.
    4. Nuclear energy contribution: Currently ~3% of India’s electricity; goal is 9-10% by 2040.

    Implications for India

    1. Energy security: Indigenous uranium critical for India’s nuclear power expansion under India’s three-stage nuclear program.
    2. Geopolitical leverage: Imports expose India to supply shocks and diplomatic constraints.
    3. Environmental justice: Mining projects risk alienating tribal populations and worsening ecological fragility.

    How should the state respond?

    1. Withdraw the OM to restore procedural legitimacy.
    2. Respect community consent to prevent democratic erosion.
    3. Explore alternatives like thorium-based nuclear energy (where India has rich reserves) and renewable energy strategies.
    4. Promote dialogue, not coercion, to avoid long-term alienation of tribal groups.

    Conclusion

    The uranium debate in Meghalaya is about much more than mining, it is about the soul of Indian democracy. By sidelining constitutional protections and environmental concerns, the state risks sacrificing long-term legitimacy for short-term gains. India’s future energy security cannot come at the cost of tribal survival, ecological stability, and democratic consent. A sustainable pathway lies in inclusive governance, diversified energy strategies, and respect for constitutional safeguards.

  • U.K, Australia and Canada recognise Palestine state in seismic shift

    Introduction

    On September 22, 2025, Britain, Australia, and Canada formally recognised Palestine as a sovereign state, a step that Portugal and potentially France are expected to follow at the UN General Assembly. This unprecedented shift, especially by G-7 members like the U.K. and Canada, alters decades of Western foreign policy and signals mounting pressure on Israel after nearly two years of the Gaza war that began with Hamas’s October 7, 2023 attack. While hailed as historic by Palestinians, Israel’s Prime Minister Benjamin Netanyahu condemned the move as an “absurd reward for terrorism.”

    Why is this development historic?

    1. First G-7 recognition: U.K. and Canada became the first G-7 nations to officially recognise Palestine, breaking with the long-standing Western alignment with Israel.
    2. Sharp contrast with past policy: For decades, Western countries had deferred recognition pending a negotiated two-state solution; this marks a direct policy shift.
    3. Conflict backdrop: The recognition comes amid international outrage over prolonged violence in Gaza since 2023, highlighting the urgency for peace.
    4. Special burden: The U.K.’s Deputy PM admitted Britain carries a “special responsibility” due to the 1917 Balfour Declaration, which paved the way for Israel’s creation.

    Why did the U.K., Australia, and Canada take this step?

    1. Reviving peace hopes: Leaders like Keir Starmer emphasised the recognition as a way to keep the two-state solution alive.
    2. International pressure: Growing calls for humanitarian accountability in Gaza pushed these governments to act.
    3. Alignment with Europe: Portugal announced recognition the same day, and France is expected to follow, indicating a coordinated Western European push.

    What has been Israel’s reaction?

    1. Harsh opposition: PM Netanyahu warned that calls for Palestinian statehood “endanger Israel’s existence.”
    2. Terrorism narrative: Israel frames recognition as a “reward for terrorism” in reference to Hamas’s October 7, 2023 attack.
    3. UN strategy: Netanyahu vowed to fight this recognition diplomatically at the ongoing UN General Assembly.

    What role does history play in this debate?

    1. Balfour Declaration, 1917: U.K.’s role in facilitating Israel’s creation still casts a shadow over West Asia’s conflict.
    2. Decades of stalemate: Palestinian statehood has been promised but deferred since the Oslo Accords of the 1990s.
    3. Burden of colonial legacy: Britain’s recognition is seen as part-redressal for its historical role.

    How does this reshape global geopolitics?

    1. U.S.–Western divide: Recognition creates divergence between U.S. policy (still opposed) and its closest allies like the U.K. and Canada, weakening the coherence of the Western bloc.
    2. Global South solidarity: Developing nations, many of whom already recognise Palestine, view this as overdue Western alignment, strengthening South–North convergence on justice and decolonisation.
    3. UN spotlight: With the General Assembly opening, Palestine’s legitimacy is expected to dominate the global agenda, elevating the conflict as a test case for multilateralism.
    4. Regional fault lines: Arab states may gain renewed diplomatic leverage, while Israel risks isolation beyond its traditional U.S. support base, potentially altering Middle East power balances.
    5. Strategic recalibration for India and Asia: Asian powers like India and China will have to navigate between historical solidarity with Palestine and strong bilateral partnerships with Israel, testing their strategic autonomy.
    6. Narrative of international law and legitimacy: Recognition by major Western democracies strengthens the normative argument for Palestinian statehood, challenging Israel’s framing of the issue as a security-only concern.

    Conclusion

    The recognition of Palestine by the U.K., Australia, and Canada is more than symbolic; it could catalyse a chain reaction of Western nations acknowledging Palestinian sovereignty. While it reignites hope for a two-state solution, it also risks deepening fault lines with Israel and the U.S.

    PYQ Relevance

    [UPSC 2018] India’s relations with Israel have, of late, acquired a depth and diversity, which cannot be rolled back.” Discuss

    Linkage: The recognition of Palestine by U.K., Australia, and Canada highlights how global powers are recalibrating their West Asia policies, creating new pressures on countries like India. While India recognised Palestine in 1988, it has simultaneously built deep and diverse ties with Israel in defence, agriculture, and technology. This mirrors the PYQ’s core theme—India’s Israel relationship is now structurally entrenched, even as balancing Palestine’s cause remains a diplomatic necessity.

  • Why low inflation is the problem

    Introduction

    Inflation in India has sharply declined in recent months, with CPI inflation at 2.27% (Aug 2024) and WPI inflation at just 0.52%. While households welcome subdued prices, this development has unsettled the government’s fiscal math. Nominal GDP growth, which forms the base for budget projections, has weakened. As a result, targets for revenue, deficit, and debt are under stress. This shift highlights the complex relationship between inflation, nominal GDP, and fiscal sustainability.

    The Problem with Low Inflation

    Why is low inflation in the news?

    India is currently witnessing one of the weakest inflation trajectories in recent years, with both CPI and WPI at historic lows. This is striking because inflation had been consistently higher earlier, often troubling households and RBI alike. Now, for the first time in years, inflation is falling so low that it is below the government’s own expectations, threatening fiscal stability. While consumers benefit from cheaper goods, the government risks losing lakhs of crores in projected revenue.

    Breaking Down the Fiscal Arithmetic

    What is the link between inflation and government finances?

    1. GDP measure: Nominal GDP = monetary value of goods/services at current prices, before adjusting for inflation.
    2. Government’s reliance: Budget estimates are framed on nominal GDP, not real GDP.
    3. Importance: Nominal GDP forms the denominator for deficit and debt ratios, making it central to fiscal health.

    How is low inflation disrupting budget math?

    1. Union Budget FY25-26 assumption: Nominal GDP growth at 10.5%, implying GDP of ₹357 lakh crore.
    2. Reality: Q1 nominal GDP growth just 8%, well below target.
    3. Revenue impact: FY26 central govt. net tax revenue projected at ₹33.1 lakh crore; lower inflation could cut receipts by ₹57,314 crore.

    Why is nominal GDP growth so crucial?

    1. Fiscal deficit & debt ratio: Targets (fiscal deficit 4.4%, debt-GDP ratio 56.1%) are achievable only if nominal GDP grows as expected.
    2. Current scenario: With weak inflation, nominal GDP falls, making deficit/debt appear larger relative to GDP.
    3. Result: Fiscal stress and need for adjustments in spending or borrowing.

    Is low inflation always bad?

    1. Positive side: Consumers enjoy stable prices, reduced cost of living, relief from food price spikes.
    2. Negative side: Weak inflation = lower nominal GDP = poor revenue realization for the government.
    3. RBI view: Deputy Governor (May 2024) warned that while lower prices help consumers, oversupply and weak pricing power can dampen private investment and industrial margins.

    What are the long-term risks?

    1. Corporate health: Lower pricing power can affect profits, discouraging capex.
    2. Employment: Weak demand growth can limit job creation.
    3. Cycle of slowdown: Weak inflation → lower nominal GDP → fiscal squeeze → reduced spending → slower growth.

    Conclusion

    Low inflation, though a blessing for households, poses structural challenges for India’s fiscal health. When inflation falls below government assumptions, it erodes revenue potential and distorts deficit ratios, threatening fiscal sustainability. Policymakers thus face the paradox of balancing consumer welfare with fiscal prudence. For India, the task ahead is not merely curbing inflation but maintaining it at an optimal, stable level to sustain growth, revenue, and investment.

    PYQ Relevance

    [UPSC 2019] Do you agree with the view that steady GDP growth and low inflation have left the Indian economy in good shape? Give reasons in support of your arguments.

    Linkage: The question assumes that low inflation alongside steady GDP growth indicates economic strength. However, as the article shows, low inflation with weak nominal GDP growth can actually strain fiscal math, reduce revenues, and slow investment. Thus, while consumers benefit, the economy may not necessarily be in “good shape” if fiscal sustainability and growth momentum are undermined.

  • Centre to simplify Quality Control Order (QCO) framework

    Why in the News?

    A NITI Aayog panel has proposed easing India’s Quality Control Orders (QCOs) by simplifying certification, assessments, and inspections to support MSMEs amid domestic and global criticism.

    About Quality Control Orders (QCOs):

    • Overview: Issued under the Bureau of Indian Standards (BIS) Act, 2016, QCOs make Indian Standards compulsory for specific products in public interest (health, environment, security, fair trade).
    • Voluntary vs. Mandatory: Normally BIS certification is voluntary, but under QCOs manufacturers/importers must obtain a BIS licence or Certificate of Conformity before production, imports, or sales.
    • Standard Mark: Products under QCOs carry the ISI mark (or Hallmark for jewellery) to indicate conformity.
    • Legal Backing: Governed by BIS (Conformity Assessment) Regulations, 2018; violation punishable with fines or imprisonment.
    • Imports: Applies equally to foreign manufacturers via the Foreign Manufacturers Certification Scheme (FMCS).
    • Coverage: Of ~23,000 BIS standards, only 187 QCOs covering 770 products exist; 84 QCOs covering 343 products issued in the last three years.
    • Example: QCOs for compressors & ACs (2023) boosted compressor output from <2 million (2021–22) to 8 million (2023–24); ACs to 12 million+ units.

    Challenges Related to QCOs:

    • High Costs: Certification involves inspections, documents, and assessments—burdening MSMEs.
    • Non-Tariff Barrier Issues: US, EU, UK, NZ claim India’s QCOs exceed global norms. USTR (2025) flagged BIS marks even for chemicals, requiring site visits.
    • Industry Pushback: MSMEs fear inflationary costs; imports of cheaper raw materials/components restricted.
    • Limited Enforcement: Only 187 of 23,000 standards notified, mainly steel, electronics, chemicals.
    • Implementation Delays: Licence approvals slow; procedures disrupt production and supply chains.
    • Conflicting Views: Some MSMEs benefit (e.g., Birla Aircon turnover jumped ₹7 crore to ₹42 crore after QCO on water coolers), others call it “malign intervention” (NITI Aayog VC Suman Berry).

    Steps Taken by Government:

    • Digitisation: Simplified certification covering 750+ products; licences granted in 30 days.
    • MSME Outreach:
      • Jan Sunwai: Online open-house thrice weekly.
      • Manak Manthan: BIS field initiative for MSME support.
      • Regional Conferences: Led by Department of Consumer Affairs to resolve issues.
    • Capacity Building: Of 50,753 BIS certifications, ~40,000 (≈80%) issued to MSMEs; 24,625 voluntarily obtained for credibility/exports.
    • Trade Readiness: Govt projects QCOs as tools to raise quality and global competitiveness.
    • WTO Consistency: Justified if linked to health, safety, environment, deceptive trade, or security, in line with WTO Technical Barriers to Trade (TBT) Agreement.

  • Extreme Nuclear Transients (ENTs) and the Big Bang

    Extreme Nuclear Transient

    Why in the News?

    New research by the University of Hawaii has discovered Extreme Nuclear Transients (ENTs), the most powerful explosions since the Big Bang, surpassing even gamma-ray bursts (GRBs) in energy output.

    Back2Basics: Big Bang

    • Proponent: In 1927 by Georges Lemaître.
    • Timeline: Universe originated ~13.7–13.8 billion years ago from a singularity.
    • Phases: Began with cosmic inflation, followed by expansion, cooling, and formation of matter, light, and four fundamental forces.
    • Cosmic Evolution: Led to atoms, stars, galaxies, and planets; universe still expanding.
    • Evidence: Supported by cosmic microwave background radiation and Hubble’s observations of galaxy redshifts.

    About Extreme Nuclear Transients (ENTs):

    • Discovery: First reported by astronomers at the University of Hawaii’s Institute for Astronomy (IfA).
    • Cause: Triggered when massive stars (≥3 times Sun’s mass) are torn apart by supermassive black holes at galactic centers.
    • Energy Output: Release ten times more energy than gamma-ray bursts (GRBs), earlier considered the brightest cosmic events.
    • Duration: Remain luminous in radio wavelengths for years, unlike short-lived bursts.

    How ENTs differ from other cosmic events?

    • Gamma-Ray Bursts (GRBs): They come from collapsing stars or mergers; short-lived but highly energetic. ENTs are more powerful and last longer.
    • Tidal Disruption Events (TDEs): TDEs also shred stars, but ENTs involve larger black holes and massive stars, making them rarer.
    • Fast X-ray Transients (FXTs): They are faint, brief X-ray bursts from trapped jets in supernovae. ENTs are brighter, multi-wavelength, and more energetic.

    Scientific Importance of ENTs:

    • Most Energetic Events: Represent the most powerful class of transients ever observed.
    • Black Hole Studies: Offer insights into supermassive black hole dynamics and their role in galactic evolution.
    • Early Universe Clues: Help probe massive stars soon after galaxy formation.
    • Future Observations: Key targets for next-generation telescopes like the Vera C. Rubin Observatory and Nancy Grace Roman Space Telescope.
    [UPSC 2012] Which of the following is/are cited by the scientists as evidence for the continued expansion of the universe?

    1. Detection of microwaves in space

    2. Observation of redshift phenomenon in space

    3. Movement of asteroids in space

    4. Occurrence of supernova explosions in space

    Select the correct answer using the code given below:

    (a) 1 and 2 * (b) 2 only (c) 1, 3 and 4 (d) None of the above.
