Context

Vice President Jagdeep Dhankhar recently criticised the Supreme Court for setting timelines for the President to grant assent to bills and described the Court’s use of Article 142 as a “nuclear missile against democratic forces.” These remarks revive the foundational debate on the doctrine of separation of powers enshrined in the Indian Constitution.

Legislature’s Perspective:

  • Legislative Sovereignty: Parliament is the primary law-making body in a representative democracy. It derives its legitimacy from the people. The Vice President’s concerns reflect fears that judicial actions are intruding into the legislative domain, affecting democratic processes.
  • Presidential Discretion and Executive Primacy: The legislature, through the Council of Ministers, advises the President. Article 74(1) mandates the President to act on this advice. Imposing judicial timelines on the President could be viewed as a restriction on executive functioning and an erosion of constitutional conventions.
  • Accountability vs Overreach: Elected representatives are directly accountable to the people through elections. If judges dictate legislative or executive timelines, it can shift the balance of accountability. The legislature fears it will be answerable for decisions not entirely under its control.

Judiciary’s Perspective:

  • Interpretation vs Legislation: While the judiciary cannot legislate, it has the power to interpret and enforce constitutional norms. In the Tamil Nadu case, it held that indefinite withholding of assent to bills violates the spirit of the Constitution — thus, it acted within its interpretative role.
  • Use of Article 142: Article 142 empowers the Supreme Court to deliver justice where the letter of the law is silent or insufficient. In the absence of a fixed time limit for gubernatorial assent, the Court filled the constitutional vacuum to uphold federalism and legislative supremacy of elected assemblies.
  • Judicial Independence: The judiciary’s role is to act as a check on potential executive or legislative excesses. It invokes constitutional morality to prevent misuse of authority, such as arbitrary delay in bill assent, which may undermine democratic processes in states ruled by opposition parties.

What is the ‘Core Issue’ (Inaction as Constitutional Evasion)?

  • Constitutional Silence ? Inaction License: Articles 200 and 201 do not prescribe a timeline for the Governor or President to act on bills. However, indefinite silence effectively amounts to a pocket veto, violating democratic and federal principles.
  • Federal Structure and Political Abuse: When a centrally appointed Governor stalls state bills, especially in opposition-ruled states, it raises serious questions on the misuse of constitutional positions. Judicial intervention seeks to protect states’ autonomy and the “will of the people.”
  • Invisibility of Inaction: Unlike active decisions, delays leave no paper trail and are harder to challenge. Courts stepping in to counter inaction is not overreach but a constitutional necessity to prevent paralysis of democratic governance.

Fact Box: Separation of Power

  • Separation of powers is a fundamental principle of democratic governance that involves distributing the functions of government among different branches:
    • Legislative: Parliament ( Lok Sabha and Rajya Sabha), State legislative bodies
    • Executive: President (central level), Governor (state level)
    • Judicial: Supreme Court, High Court and all other subordinate courts
  • This distribution aims to prevent the concentration of power in any single branch and to ensure that each branch operates independently yet cooperatively.
  • While the Indian Constitution does not explicitly use the term "separation of powers," it implicitly incorporates the concept by allocating distinct functions and powers to the Legislature, Executive, and Judiciary.
  • Separation of powers is not absolute. The Constitution establishes a functional overlap to ensure cooperation and checks.
Checks and Balances Mechanisms
  • Checks and balances are fundamental mechanisms within a democratic system that prevent any single branch of government from gaining too much power.
  • In India, these mechanisms are essential for maintaining a balanced governance structure where the Legislature, Executive and Judiciary operate independently yet interdependently.
  • The Indian Constitution’s Doctrine of Checks and Balance was introduced by the Supreme Court in the 1993 decision of Kannadasan v. Tamil Nadu State.

Legislative Checks

Executive Checks

Judicial Checks

  • No-Confidence Motions: The government must resign if it loses the confidence of the majority in Parliament.
  • Question Hour and Censure Motions: Ministers must answer questions posed by Parliament members, and Parliament can express disapproval of the Executive’s actions through censure motions.
  • Ordinances: The Executive can issue ordinances during Parliamentary recesses, though these must be approved by Parliament to remain effective.
  • The Executive operates within the framework set by the Legislature and is subject to judicial review of its actions.
  • Article 13: If a statute is arbitrary or unconstitutional, the judiciary has the authority to invalidate it.
    Additionally, it has the authority to deem unconstitutional presidential actions void.
  • Impeachment and Removal Procedures: Articles 61 and 124(4) of the Constitution detail the impeachment procedures for the President and Supreme Court judges, respectively.

The India Justice Report (IJR) 2025 has once again spotlighted the severe overcrowding in Indian prisons, the growing number of undertrial prisoners, and the persistent shortfalls in judicial, legal aid, and prison reforms. This is especially alarming as it comes amidst global scrutiny of India’s prison conditions, which has even impacted high-profile extradition cases.

Notably, two jails in Delhi's Tihar complex are operating at over 400% capacity, and across India, undertrials form 76% of the prison population, raising constitutional and human rights concerns.

Key Findings of the India Justice Report 2025 (IJR 2025)

  • Overcrowding and Infrastructure Crisis
    • 176 prisons have an occupancy rate of over 200%.
    • 12 prisons are running at 400% capacity or more.
    • Tihar Jail’s Central Jails 1 and 4 have occupancy rates of 411% and 467%, respectively.
    • National average prison overcrowding stands at 131%.
    • Only 68% of inmates have access to adequate sleeping space.
  • Undertrial Crisis: Undertrial inmates form 76% of the total prison population — the highest ever. In Delhi, undertrials make up 91% of the jail population. In 6 states and UTs, more than half the inmates have been in jail for over 3 years. Trial pendency is highest in Bihar (71%), followed by West Bengal and Odisha.
  • Legal Aid Gaps: 38% drop in paralegal volunteers since 2019. Despite new schemes like Legal Aid Defence Counsel (LADC) and jail clinics, resource allocation for community-based interventions is shrinking. Haryana showed the most improvement in legal aid delivery.
  • Judicial Infrastructure and Human Resource Deficit: India has only 15 judges per million people (against the Law Commission's 1987 recommendation of 50). Vacancies in lower judiciary are a key factor in trial delays and undertrial incarceration.
  • Budget Utilisation Paradox: Prison budget allocation increased by 156%, and budget for prisoners by 192% in the last decade. Per day expenditure per prisoner increased from Rs 62 to Rs 121. Despite this, fund utilisation is poor, and infrastructure has not kept pace with rising demand.

What Does the IJR 2025 Tell Us About Indian Prisons?

  • Chronic Overcrowding, a Structural Problem: The persistent overcrowding of jails is not just a symptom of crime, but a failure of legal processes, administrative delays, and judicial vacancies. The absence of effective bail systems, and lack of fast-track courts for petty offences, exacerbates this.
  • Undertrials:  The fact that 3 out of every 4 inmates are undertrials — presumed innocent in law — reflects a grave miscarriage of justice. This raises ethical, legal, and constitutional questions, particularly under Article 21 (Right to Life and Liberty).
  • Legal Aid Mechanism is Uneven and Underperforming: While initiatives like LADC systems and Lok Adalats are commendable, the erosion of paralegal and community legal networks shows a disconnect between policy vision and on-ground implementation.
  • Poor Prison Conditions Affect Diplomacy and Human Rights Image: As noted by former SC judge Justice Lokur, India’s poor prison conditions are cited in foreign courts to block extraditions — this has serious implications for transnational justice and India's international credibility.
  • Budget Increases Without Outcome-Focus is Futile: The near doubling of prisoner-related expenditure hasn't led to better living standards or rehabilitation programs. This points to poor planning, lack of monitoring, and absence of accountability in the prison administration system.
  • Gender & Diversity Improvements Are Welcome but Not Sufficient: Progress like a rise in women in policing and judiciary (38%) is notable. But the absence of adequate infrastructure, such as women’s help desks in all stations, separate facilities in jails, or rehabilitation for marginalized groups, makes such progress fragile.

Union Commerce and Industry Minister Piyush Goyal’s recent remarks at the Startup Mahakumbh 2025 have reignited a national debate: Are Indian startups innovating enough or merely scaling convenience? By highlighting concerns that startups are focusing excessively on low-tech services like grocery and ice-cream delivery, the Minister underscored a deeper tension within India’s economic trajectory—whether its startup ecosystem is pushing the frontier of innovation or plateauing in market replication.

The state of Indian Startups

  • India has earned its place as the 3rd largest startup hub globally, with over 100 unicorns shaping the future of innovation and entrepreneurship.
  • Recognised as a powerhouse of entrepreneurial spirit, the country boasts of 157,066 startups acknowledged by the department for promotion of industry and internal trade (DPIIT) with more than 1.6 million jobs created.
  • However, Indian startups for being too narrowly focused on low-tech, consumer-facing sectors like grocery and ice cream delivery, and not much focused on real ‘innovation’.

What counts as innovation?

  • Innovation in the startup context is not monolithic. It can be categorized as:
    • Incremental innovation (e.g., improving delivery logistics)
    • Disruptive innovation (e.g., ride-sharing or fintech platforms)
    • Deep-tech or science-led innovation (e.g., AI chips, quantum computing, 3D manufacturing)
  • Piyush Goyal’s critique is implicitly aimed at the lack of deep-tech innovation—where startups serve as bridges between fundamental science and commercial application.

Why is Deep-Tech Innovation Scarce?

  • High capital requirements
  • Long gestation periods
  • Absence of early revenue
  • Need for skilled researchers and advanced infrastructure
  • Lower risk appetite among Indian VCs and banks
    • Despite over 1,65,000 startups, only a small fraction operate in robotics, clean energy, AI/ML, or advanced manufacturing. This is not for lack of ambition, but due to ecosystem constraints—a classic structural bottleneck.
Innovation and the Role of Capital:
  • Domestic vs Foreign Capital Divide: India's startup ecosystem is primarily funded by foreign venture capital (VCs)—mostly from the U.S., Japan, and China. Domestic capital, especially risk capital from Indian investors or institutions, remains scarce. Piyush Goyal’s call for greater domestic investment points to a need for financial sovereignty and resilience.
  • Short-Termism in Indian Capital: Indian capital tends to chase:
    • Fast-scaling platforms
    • Low-capex ventures
    • Proven business models from the West
  • This short-term orientation undermines experimental and patient capital, which is essential for building futuristic technology and global competitiveness.
  • Structural Problem in VC Logic: Venture capital logic often requires:
    • Scalability within 3-5 years
    • Exit via acquisition or IPO
    • Demonstrable market traction
    • Deep tech doesn’t align neatly with this. Without IP-driven competitive advantage, investors will hesitate. Therefore, market failure in venture funding limits the types of innovation pursued.
Required Measures (Towards a Mature Innovation Ecosystem)
  • Strategic Deep Tech Missions: There is need to lnk startups to national missions (clean energy, space, semiconductors).
  • Reform Venture Funding Logic: Provide blended finance (government + VC) for patient capital in R&D.
  • Encourage Indian LPs (Limited Partners): The government should incentivise Indian family offices, banks, pension funds to invest in VC.
  • Decentralised Innovation Clusters: Build regional tech hubs linked with local universities.
  • IP and Patent Ecosystem: There is need to strengthen India's IP infrastructure and expedite patent approvals.
  • Regulatory Sandboxes: Let startups test products without full compliance during early stages.
  • Enhance Corporate Governance: Cases like Byju’s show the need for stronger transparency and audit norms.
Fact Box:  Comparison with China and the United States

China’s Model: Techno-Nationalism and Scale

  • Centralised planning
  • Heavy state subsidies for AI, EVs, chip fabrication
  • Protected domestic markets
  • Strong incentives for private players to align with national goals

India lacks such strategic clarity, though it aspires to technological self-reliance.

U.S. Model: Risk-Tolerant Capitalism

  • Deep and patient private capital
  • University-VC-startup triad
  • National procurement (NASA, DARPA) to support deep tech

India has parts of both models, but lacks the institutional cohesion and mission-driven orientation of either.

Context

In a significant development, a biotechnology firm in Texas (Colossal Biosciences), announced the birth of genetically modified wolf pups — claimed to be “resurrected” dire wolves, extinct for over 12,000 years.

What Has Been Achieved?

  • Colossal Biosciences used genome editing to make gray wolves genetically resemble the extinct dire wolf:
    • The gray wolf (Canis lupus) and the dire wolf (Aenocyon dirus) share 94% genetic similarity.
    • The company edited 20 loci across 14 genes in the gray wolf genome, focusing on traits like size and fur — largely cosmetic traits.
    • Embryos with edited DNA were implanted in dog surrogates, resulting in pups named Romulus and Remus.
  • However, only a fraction (possibly 0.02%) of the actual genetic difference between the two species was altered. Crucially, behavioral, social, and ecological traits are shaped by the entire genome and environment — not just appearance.
  • These are not true dire wolves, but genetically modified gray wolves engineered to look like

Why is De-Extinction Controversial?

  • Ecological Risks: Habitats have changed drastically since these species went extinct. Climate, prey species, and ecosystems have evolved — reintroducing ancient species may cause unintended disruptions.
  • Genetic Uncertainty: Partial genome editing can’t recreate the full complexity of extinct species. Behavioral traits, immunity, reproduction, and adaptability are unknown variables.
  • Ethical and Regulatory Concerns: Animal welfare during gene editing and surrogacy is questionable. May divert attention and funding from protecting endangered species and conserving ecosystems.
  • Policy Misuse: Colossal’s announcement was used to justify regulatory rollbacks in the U.S., as seen with the Trump-era rhetoric that "innovation, not regulation" would protect biodiversity.

Can Ancient Species Thrive in Today’s World?

  • Conservation is shifting toward high-tech interventions. Conservation efforts should prioritize ecosystem resilience, biodiversity corridors, and habitat protection — not nostalgia-driven rewilding of prehistoric species.
  • Ancient species evolved under specific environmental conditions — temperature, food sources, competitors — that no longer exist.
  • Modern human-dominated landscapes may not support their reintroduction.
  • Risk of becoming invasive species or failing to survive is high.
About Extinct Dire Wolf
  • The dire wolf was a very large carnivore that lived in the Americas about 10,000 years ago.
  • Anatomically, it resembled a big, muscular, extra-toothy grey wolf: the species alive today that everyone thinks of when they say “wolf”.
  • Dire wolves belong to a separate canid lineage, not closely related to modern wolves.
    • They have since been reclassified as Aenocyon dirus, not Canis dirus.
    • Their evolution, behavior, and ecological niche were fundamentally different from gray wolves.
De-Extinction
  • De-extinction, or resurrection biology, is the process of recreating extinct species using biotechnology. 
  • Methods:
    • Cloning: Cloning is creating a copy of cells.
    • Genome editing: Genome editing involves recreating extinct species by modifying the genome of a closely-related species, using the extinct species’ genome. Advanced biotechnology such as CRISPR-cas9 could be used.
    • Back-breeding: In back-breeding, ancestral phenotypes may be resurrected after many generations, but the genes that underlie these phenotypes may differ from those that were present in the extinct species. 
Genome Editing
  • Genome editing technology creates hybrids between living and extinct organisms. 
  • Scientists insert edited DNA from an extinct species into the nucleus of a reproducing cell.
  • They use this technique to resurrect more species, including those whose remains are not well-preserved.
  • Genome editing blends the desired traits that made the species unique with genes from the donor species.
  • That is why the resulting organism is not completely identical to the extinct species but is a hybrid.

A new study by the National Institute of Advanced Studies (NIAS), Bengaluru recommends a rollback of the Environment Ministry’s 2015 mandate requiring all 537 coal-fired power plants in India to install Flue Gas Desulphurisation (FGD) systems.

What is FGD?

  • Flue Gas Desulphurisation (FGD) is a pollution control technology that removes sulphur dioxide (SO?) from the exhaust flue gases of fossil-fuel power plants.
  • It was mandated in 2015 to tackle India’s rising SO? emissions. The deadline for installation was 2018, but due to slow compliance, it has been extended to 2027–2029, depending on plant category.
  • SO? contributes to acid rain, respiratory illnesses, and air pollution. FGDs were intended to curb these health and environmental risks.

What Does the NIAS Study Argue?

  • FGD Not Needed at All Plants: 92% of Indian coal is low-sulphur (0.3%–0.5%). Thus, FGD should only be mandated for plants using imported/high-sulphur coal.
  • Low Risk of Acid Rain in India: Acid rain is not a significant issue in India. Stack heights (minimum 220 m) and climatic conditions disperse SO? adequately.
  • Environmental Trade-Off: Installing FGDs would:
    • Increase CO? emissions by 69 million tonnes (2025–2030) due to higher energy and water use.
    • Reduce SO? by 17 million tonnes — but this trade-off may worsen global warming.
  • Focus on Particulate Matter (PM) Instead: PM pollution from coal plants is more harmful due to high ash content in Indian coal.

Fact Box: Sulphur dioxide (SO2)

  • Sulphur dioxide (SO2) is a heavy, colourless, and poisonous gas with a pungent and irritating odour. Its smell is often described similar to that of a burnt matchstick.
  • The gas forms secondary particulate matter (PM2.5) when it oxidizes to sulphuric acid (H2SO4) by combining with water vapour.
  • It also reacts with ammonia (NH3) to create another dangerous compound called ammonium sulphate ((NH4)2SO4).
  • SO2 also contributes to sulphurous smog, which results from a high concentration of sulfur oxides (SOx) in the atmosphere and is exacerbated by dampness and particulate matter (PM).
  • Health impact of sulphur dioxide: Lung function, worsen respiratory diseases, Wheezing, shortness of breath, chest tightness, Aggravation of asthma and chronic bronchitis, Inflammation of the respiratory tract (coughing, mucus secretion), Eye irritation
  • Environmental impact: Acid rain, Damaging of vegetation, Depriving soil of essential nutrients (calcium, aluminum, magnesium)

Scientists at the University of Cambridge, using data from NASA's James Webb Space Telescope (JWST), have detected potential biosignatures — molecules associated with life — in the atmosphere of exoplanet K2-18b, located 124 light years away. While not conclusive, this is the strongest signal yet in the search for extraterrestrial life.

What Did Scientists Detect?

  • The James Webb Space Telescope (JWST) has detected traces of Dimethyl Sulphide (DMS) and Dimethyl Disulphide (DMDS) in the planet’s atmosphere.
    • On Earth, DMS and DMDS are considered biosignatures — produced by simple life forms. If confirmed, this would be the first strong evidence of life beyond Earth.
  • On Earth, these gases are only produced by living organisms, especially marine phytoplankton and bacteria.
  • The detected quantity is thousands of times higher than levels on Earth—suggesting the possibility of abundant biological activity (if the source is life-related).
  • How Was This Detected? Using infrared spectroscopy, JWST studied how the planet’s atmosphere absorbs starlight. This absorption pattern gives scientists clues about what chemicals are present in the atmosphere.
  • Alternate Explanations: Gases could be produced through non-biological (abiotic) processes such as:
    • Geological reactions.
    • Molten oceans (not conducive to life).
    • Mini gas giant structure with no solid surface.

What is K2-18b?

  • K2-18b is an exoplanet (planet outside our solar system) orbiting a red dwarf star in the constellation Leo.
  • It is roughly 2.5 times the size of Earth.
  • It is located 124 light years (approx. 700 trillion miles) away.
  • It is likely situated within its star’s habitable zone — where conditions might allow for liquid water.
  • K2-18b is part of the “sub-Neptune” class of nearly 6,000 exoplanets that have been discovered beyond the solar system since the 1990s.

The Kerala State Electricity Board (KSEB) and IIT Bombay have launched a pilot project to explore V2G technology. The goal is to assess the feasibility of using electric vehicles (EVs) to support Kerala’s electricity grid, especially during peak demand hours.

What is V2G?

  • Vehicle-to-Grid (V2G) refers to a system where electric vehicles (EVs) not only consume electricity but also send power back to the grid when needed.
  • This is made possible through bi-directional chargers that allow EVs to both charge and discharge.
  • Key Modes:
  • G2V (Grid-to-Vehicle): EVs draw power from the grid to charge.
  • V2G (Vehicle-to-Grid): EVs supply power back to the grid.
  • Other variants:
    • V2H (Vehicle-to-Home): Powers household appliances.
    • V2V (Vehicle-to-Vehicle): Transfers charge between vehicles.

Global Applications:

  • It is widely tested in Europe, U.S., and Japan.
  • In countries like the U.K. and The Netherlands, EV users are paid for supplying electricity during peak hours.
  • California uses V2G for grid stability and emergency backup during climate disasters.
  • Electric buses have been successful in V2G pilot programs globally.

The Supreme Court, in State of Tamil Nadu vs. Governor of Tamil Nadu (2025), held that the Governor’s prolonged inaction on state bills was unconstitutional. Using Article 142, the Court deemed the bills to have received assent, restoring federal balance but raising debates on constitutional accountability and judicial overreach.

Judicial Intervention and Constitutional Inaction

  • Unequal Timelines – Contrasting Judicial Priorities: While the Supreme Court swiftly heard petitions against the Waqf (Amendment) Act 2025, it took five years to address the Governor's inaction on Tamil Nadu's pending bills from 2020.
  • Federal Erosion – Impact of Governor’s Inaction: Failure to assent to state legislation undermines elected governments, dilutes legislative intent, and distorts the federal framework, especially when Centre and State are politically opposed.
  • Legal Immunity – Challenges of Accountability: Governors enjoy constitutional immunity under Article 361; their inaction, being undocumented, often escapes judicial scrutiny, leaving states without legal recourse.

Article 142 and Judicial Remedy

  • No Pocket Veto – Interpreting Articles 200 and 201: The Court clarified that the Constitution does not allow indefinite withholding of assent; inaction beyond a reasonable period violates constitutional responsibility.
  • Extraordinary Remedy – Use of Article 142: Citing constitutional silence, the Supreme Court invoked Article 142 to do “complete justice,” deeming the bills assented, a first-of-its-kind intervention in legislative process.
  • Rapid State Action – Tamil Nadu’s Response: Following the ruling, the Tamil Nadu government immediately notified the Acts, implementing the legislative intent delayed by the Governor's withholding of assent.

Accountability and Constitutional Implications

  • Finding of Mala Fide – Governor’s Conduct Questioned: The Supreme Court held that the Governor acted without bona fides, disregarding Court directions and constitutional duties, severely breaching constitutional trust.
  • Political vs Legal Accountability – Quo Warranto as Option: Though political calls for resignation have been made, legal accountability could be sought through a writ of quo warranto, challenging the Governor’s continuance.
  • Subversion by Inaction – Growing Threat to Basic Structure: A trend of bypassing constitutional norms through inaction, rather than amendment, threatens constitutionalism and fuels calls to dismantle the Basic Structure doctrine and collegium system.
Practice Question:
Q. In light of the recent Supreme Court judgment in State of Tamil Nadu vs. Governor of Tamil Nadu, critically examine the constitutional position, powers, and accountability of Governors in India. How does judicial interpretation under Article 142 shape Centre-State relations?

An Olive Ridley turtle tagged as 03233, originally from Gahirmatha beach in Odisha, completed an extraordinary 4,500 km migratory journey to Guhagar beach in Maharashtra, leading to a successful nesting — a rare feat documented in turtle conservation history.

Conservation and Ecological Significance

  • New Migration Pattern – Shift in Conservation Maps: Turtle 03233's route expands known Olive Ridley migratory corridors beyond Odisha's mass nesting sites, warranting updates in marine conservation zones.
  • Cross-Coastal Ecology – India’s Marine Biodiversity: This journey, possibly circling Sri Lanka, underlines the need for integrated marine ecosystem policies across eastern and western coasts.
  • First-of-its-Kind Record – Scientific Breakthrough: If confirmed, this would be the first documented long-range migration among Olive Ridleys in the Indian Ocean, altering existing scientific assumptions.

Conservation Technology and Challenges

  • Tagging Tools – Cost-effective Tracking Methods: Titanium and inconel flipper tags, while affordable, offer limited accuracy compared to GPS, highlighting the need for scalable yet precise tracking technologies.
  • Data Gaps – Need for Research Infrastructure: The uncertainty in tracking underscores the need for long-term ecological monitoring systems and marine biodiversity data platforms.
  • Policy Implication – Protection Beyond Arribada Zones: Conservation efforts must extend to less-known nesting beaches like Guhagar, ensuring decentralised protection of turtle habitats.

Symbolism and Environmental Ethos

  • Endurance as Ecological Insight – Long-term Survival Strategies: The turtle’s solitary journey is a metaphor for resilience, reflecting species adaptation in unpredictable marine ecosystems.

Context

A paper co-authored by a Cambridge scientist suggested the presence of possible biosignatures like dimethyl sulphide (DMS) in the atmosphere of exoplanet K2-18b, raising cautious optimism about the possibility of life beyond Earth. The news made headlines but also highlighted issues of scientific uncertainty, media hype, and political threats to curiosity-driven research.

Scientific Discovery and Analysis

  • Exoplanet of Interest – K2-18b: Astronomers have long been interested in K2-18b due to its unique surface physiochemistry and habitable zone location around a red dwarf star.
  • Detected Compounds – Possible Biosignature: Researchers detected dimethyl sulphide or dimethyl disulphide in K2-18b’s atmosphere; on Earth, DMS is primarily produced by biological processes.
  • Scientific Temper – Need for Caution: Authors and external experts urge cautious interpretation, emphasizing data refinement, replication, and the high probability of overturning in such studies.

Challenges in the Practice of Science

  • Pattern of Overhype – Media vs Research: The paper’s conservative conclusions were overshadowed by sensational press headlines like “Strongest hints yet of biological activity,” distorting scientific discourse.
  • Vulnerability to Misinformation: When curiosity-driven science is sensationalized or politicized, it becomes susceptible to public misinformation and ideological manipulation.
  • Funding Threats – Undermining Free Inquiry: The politicization of scientific funding, especially in the U.S., affects global research agendas by selectively targeting institutions and subjects.

Political Interference in Scientific Funding

  • Trump’s Policies – Financial Sanctions on Academia: The Trump administration linked university funding with curtailment of DEI (Diversity, Equity, Inclusion) programs and protest activities, threatening institutional autonomy.
  • Budget Cuts – NASA and NOAA Impacted: The 2026 budget proposal includes a 27% cut to NOAA, major reductions to NASA’s Goddard Space Flight Center, and halving of its earth-science budget.
  • Ideological Bias – Republican State Doctrine: The funding redirection aims to suppress scientific disciplines not aligning with conservative ideology, constraining exploration in space, climate, and life sciences.
Practice Question:
Q. Scientific exploration in the 21st century increasingly finds itself constrained by political and ideological forces. Critically examine the implications of such constraints on curiosity-driven research, with suitable examples from space science and climate studies.
