  • What psychiatric genetics can and cannot tell an Indian family

    Why in the news?

    Families of patients with psychiatric illness increasingly ask whether the condition is in their blood and whether a genetic test can settle their child’s future. There is a tension between the real progress of psychiatric genetics and its limited power to predict individual outcomes, especially for Indian populations underrepresented in genomic databases. The central point is that genes load the dice but do not determine destiny.

    What is a genome-wide association study (GWAS)?

    1. About: A GWAS compares millions of common genetic variants across very large groups of people with and without a condition, to find variants that appear more often in one group. . It compares DNA markers, most often single-nucleotide polymorphisms (SNPs, between individuals with a condition and healthy control groups.
    2. What it yields: It behaves like a satellite map highlighting genomic areas of interest, showing where to look for biological mechanisms rather than pinpointing a cause.

    What does polygenic risk mean?

    1. About: In common psychiatric disorders no single gene variant has a large effect, unlike single-gene diseases such as Tay-Sachs disease or Duchenne muscular dystrophy.
    2. Mechanism: Risk is polygenic, emerging from the combined influence of thousands of variants together with rare genetic changes, development, environment, and chance.

    What is a polygenic risk score?

    1. About: A polygenic risk score (PRS) compresses many small genetic effects into a single number meant to estimate a person’s inherited susceptibility.
    2. Limits: It cannot say whether a person will become ill, at what age, how severe it will be, or which medicine will work, because it captures only part of genetic liability.

    How Polygenic Risk Works

    1. Many small changes: Instead of one major gene causing an illness (like in cystic fibrosis), polygenic conditions involve hundreds or thousands of tiny DNA changes called single nucleotide polymorphisms
    2. Adding it up: Each individual variant adds or subtracts a tiny amount of risk; a PRS totals these up to estimate your overall genetic predisposition.
    3. Common conditions: It applies to complex diseases like heart disease, type 2 diabetes, schizophrenia, and certain common cancers

    What have the major GWAS findings shown?

    1. Schizophrenia: A 2022 landmark study identified associations at 287 genomic regions and pointed to genes active in neurons and synapses.
    2. Bipolar disorder: A large 2021 study identified 64 associated regions.
    3. Regulatory signals: Many signals lie in DNA that regulates when and where genes switch on, not in stretches that directly encode a protein.
    4. Shared risk: A December 2025 study in Nature reported that some inherited risk is shared across schizophrenia and bipolar disorder.

    Why is prediction unreliable, especially in India?

    1. Score does not contain life: A person with a higher score may remain well while a person with a lower score may fall ill, because the score does not contain childhood adversity, sleep disruption, substance use, medical illness, or access to care.
    2. Expert caution: The International Society of Psychiatric Genetics has cautioned that current scores for schizophrenia, bipolar disorder, and depression are not accurate enough for routine clinical prediction.
    3. Ancestry bias: Genomic databases have drawn disproportionately from people of European ancestry, so scores are often less accurate in other populations.
    4. Indian diversity: The GenomeIndia project generated whole-genome data from 10,000 healthy, unrelated Indians across 83 population groups and documented extraordinary genetic diversity, so a score developed elsewhere cannot simply be imported.

    What can genetics usefully change in the clinic today?

    1. Reduces blame: A mother did not cause schizophrenia by being too strict and a father did not transmit bipolar disorder through a moral failing, and biology matters.
    2. Avoids fatalism: Genetic vulnerability should not be converted into a verdict, and no test can declare a person safe or doomed.
    3. Focus on modifiable risk: The useful approach is to track early warning signs, avoid intoxicants, sleep well, seek help promptly, and focus on recovery.
    4. Visible risks: Many risks are visible without sequencing, such as lost sleep before a manic episode, escalating cannabis use, treatment stopped due to stigma, and distance from specialist care.

    Conclusion

    The central idea is that psychiatric genetics will not identify people before they fall ill, but it can replace superstition and blame with a more accurate account of vulnerability. Prediction will remain probabilistic even as datasets grow larger and more representative. The task is to keep probabilities from being misunderstood, stigmatised, or commercialised, and to involve diverse populations while protecting privacy.

  • The missing ‘reuse’ principle in India’s EV transition journey

    Why in the News?

    India’s electric mobility transition is gathering momentum as adoption rises and circular economy principles enter industrial policy. India’s policy has advanced the recycling tier of circularity through scrappage but neglected the higher priority reuse tier, exposing a gap where structurally sound vehicles are scrapped rather than retrofitted.

    What is the circular economy hierarchy?

    1. Definition: The circular economy is built on a hierarchy that prioritises reducing resource consumption, then reusing existing assets, and only recycling materials once products have genuinely reached the end of their useful life.
    2. Reuse versus recycle: Recycling recovers materials after a product becomes waste, while reuse preserves functionality before the asset becomes waste. Reuse sits higher in the hierarchy.

    What is vehicle retrofitment?

    1. What it is: Retrofitment replaces the internal combustion engine, fuel system, and related components of an existing vehicle with an electric powertrain, while retaining the core vehicle structure.
    2. Why it counts as reuse: By keeping a structurally sound chassis and body in service, it preserves and extends the value already embedded in the asset rather than recovering value only after the vehicle becomes waste.

    How far has India progressed on recycling?

    1. Rules framework: The Motor Vehicles (Registration and Functions of Vehicle Scrapping Facility) Rules, 2021, and the Environment Protection (End of Life Vehicles) Rules, 2025, strengthened responsible vehicle recycling and material recovery.
    2. Facilities on ground: As of January 2026, 129 Registered Vehicle Scrapping Facilities were operational across 21 States and Union Territories.
    3. Vehicles processed: About 4.3 lakh vehicles had been processed through these facilities, building a formal ecosystem for recycling and resource recovery.

    Why does retrofitment matter?

    1. Per vehicle waste: A single two wheeler generates approximately 90 kilograms of recyclable material and 18 kilograms of landfill waste when scrapped.
    2. Fleet scale burden: Scaled across India’s fleet of about 30 crore vehicles, a scrap first approach would generate 2.7 crore tonnes of recyclable material and 0.54 crore tonnes of landfill waste.
    3. SDG alignment: Retrofitment supports United Nations Sustainable Development Goal 12 on responsible consumption and production by reducing material demand and waste.
    4. Old but sound: A vehicle can be old yet retain a strong chassis, intact body, and years of service life, making retrofitting more circular than scrapping.

    What is the three pathway vehicle hierarchy?

    1. First pathway, continued use: Vehicles that remain safe, compliant, and efficient should keep operating with routine maintenance, since age alone should not trigger removal.
    2. Second pathway, retrofitment: Vehicles with sound structure but ageing or polluting powertrains can be converted to electric through certified processes, extending life while cutting emissions.
    3. Third pathway, scrappage: Vehicles with compromised safety, severe structural degradation, accident damage, or significant corrosion proceed to scrappage and recycling.

    The missing middle path

    1. Not a competition: Retrofitment is not a competing strategy to scrappage but the missing middle path that policy has not focused on yet.
    2. Condition over age: Treating every ageing vehicle as a disposal candidate overlooks the chance to extend asset life while accelerating electrification.
    3. Public acceptance: A condition assessed transition would make scrappage more acceptable, as citizens would see that older vehicles are assessed for transformation rather than dismissed indiscriminately.

    What are the challenges to a reuse led EV transition?

    1. Certification gap: Retrofitment needs robust certified conversion technology and testing standards to ensure safety.
    2. Cost and financing: Conversion costs can rival buying a new two wheeler, limiting uptake without incentives.
    3. Battery supply dependence: Electric powertrains depend on imported cells and critical minerals, a supply chain vulnerability.
    4. Policy bias toward scrappage: Existing incentives favour scrappage and new vehicle purchase, leaving reuse unsupported.
    5. Skilled workforce shortage: A trained network of certified retrofit workshops is largely absent at scale.
    6. End of life battery waste: Retrofitted vehicles eventually generate battery waste requiring recycling infrastructure.

    Conclusion

    India’s transport transition is a question of resource efficiency, not a contest between new electric vehicles and older ones. Adopting an age assessed pathway that distinguishes continued use, retrofitment, and scrappage would align the transition with genuine circular economy principles. This would prevent waste before it is created and confine recycling to vehicles that have truly reached the end of their useful life.

    What is Circular Economy? (Foundational Context)

    1. About: A circular economy keeps materials and products in use for as long as possible, extracting maximum value before recovery and regeneration, in contrast to the linear take, make, dispose model.
    2. Rationale: It exists to cut resource extraction, greenhouse gas emissions, and waste while sustaining economic value.
    3. Named hierarchy: It rests on reduce, reuse, and recycle in that order of priority, with reduce and reuse ranked above recycling.

    Key Concerns Regarding the Circular Economy

    1. Recycling bias: Policy attention concentrates on recycling while the higher value reduce and reuse tiers are neglected.
    2. Informal sector dominance: Much recycling occurs in the informal sector with poor environmental and safety standards.
    3. Extended producer responsibility gaps: Enforcement of producer take back obligations remains weak.
    4. Data deficits: Weak material flow data limits measurement of circularity outcomes.

    Back2Basics: Sustainable Development Goal 12

    1. What it is: SDG 12 is the goal on responsible consumption and production within the 2030 Agenda for Sustainable Development.
    2. Adopted: It was adopted by United Nations member states in 2015.
    3. Focus: It targets sustainable consumption patterns, resource efficiency, and reduced waste generation.
    4. Relevance: Vehicle retrofitment directly advances its call for better resource efficiency and reduced waste.

    Government Initiatives for EVs and Circularity

    1. PM E-DRIVE Scheme: Provides demand incentives for electric two and three wheelers and other electric vehicles.
    2. FAME India Scheme: Faster Adoption and Manufacturing of Electric Vehicles, supporting demand and charging infrastructure.
    3. Vehicle Scrappage Policy: Encourages phasing out of unfit and polluting vehicles through registered scrapping facilities.
    4. Battery Waste Management Rules, 2022: Mandate extended producer responsibility for battery recycling.
    5. PLI schemes: Production Linked Incentives for advanced chemistry cell batteries and automobiles.

    Way Forward

    1. National vehicle hierarchy: Adopt a framework treating vehicles by condition rather than age alone.
    2. Certified retrofit ecosystem: Standardise conversion technology and expand certified workshops.
    3. Incentivise reuse: Extend fiscal support to retrofitment on par with scrappage and new purchase.
    4. Strengthen battery circularity: Build reverse logistics and recycling for end of life batteries.
    5. Skilling: Train technicians for certified electric powertrain conversion.

    “[2025] Consider the following statements:

    Statement I: Circular economy reduces the emissions of greenhouse gases.

  • Evidence of non-Mendelian inheritance in mice

    Why in the News

    Researchers have reported evidence of non-Mendelian inheritance in mice, involving DNA methylation, genomic imprinting and paramutation. Nanopore sequencing helped detect these epigenetic marks.

    What is Epigenetic Inheritance?

    1. Definition: Transmission of heritable changes in gene activity without altering the underlying DNA sequence.
    2. Major mechanism: Chemical modifications such as DNA methylation can influence whether genes are switched on or off.
    3. Non-Mendelian: Unlike classical Mendelian inheritance, the inherited information is not limited to changes in the DNA sequence.
    4. Genomic imprinting: Expression of certain genes depends on whether they are inherited from the mother or father.
    5. Paramutation: One allele can induce a heritable change in the expression of another allele without changing its DNA sequence.
    6. Nanopore sequencing: Can detect certain DNA modifications, including methylation, while sequencing DNA.

    Why does it matter?

    • Expands inheritance theory: Heritable information can involve regulatory/epigenetic states in addition to DNA sequence.
    • Environment and inheritance: Some environmental factors can influence epigenetic states, though not every acquired epigenetic change is necessarily inherited.
    • Disease relevance: Abnormal epigenetic regulation is associated with cancers and other diseases.
    • Biotechnology: Advanced sequencing can help identify epigenetic modifications alongside DNA sequences.

    What is an AI Agent?

    • AI Agent: An AI system that can perceive, plan, decide and act toward a goal with limited human supervision.
    • Unlike a conventional AI model that mainly generates an output, an agent can use tools, access systems and execute actions.
    • Core feature: Autonomy + goal-directed action

    What did the Tests Reveal?

    • Agents sometimes acted beyond their given instructions.
    • Such behaviour indicates that increasing autonomy can create risks beyond conventional software bugs or model errors.
    • Findings involved OpenAI, Anthropic, Meta and the UK AI Security Institute.

    Alignment Failure vs Capability Failure

    Alignment Failure

    • AI’s behaviour or strategy conflicts with human intent.
    • The system may technically pursue its objective but do so in an unauthorised or undesirable manner.

    Capability Failure

    • AI fails because of inadequate capability, reasoning or execution.
    • The problem is inability rather than deliberate deviation from the intended objective.

  • RDI deep-tech fund: most beneficiaries linked to selection panel

    Why in the News

    An investigation found that 15 of the 22 companies receiving the first round of assistance from the Research, Development and Innovation (RDI) Fund had investment links with members of the fund’s selection committee. The panel approved Rs 2,192 crore in soft loans, raising concerns over conflict of interest and transparency.

    What is the Research, Development and Innovation (RDI) Fund?

    • Definition: A Rs 1 lakh crore fund to support private sector research in strategic and deep tech sectors.
    • Focus Areas: Artificial Intelligence, Quantum Technology, Space, Defence, Robotics, Clean Energy, Semiconductors and Digital Healthcare.
    • Financial Support: Collateral free loans up to 50% of project cost, at 2 to 4% interest for up to 15 years.
    • Custodian: Managed through a Special Purpose Fund under the Anusandhan National Research Foundation (ANRF).
    • Fund Managers: Loans are disbursed through Second Level Fund Managers (SLFMs), currently the Technology Development Board (TDB) and Biotechnology Industry Research Assistance Council (BIRAC).

    How are companies selected?

    • Investment Committees: Each SLFM forms an independent investment committee to evaluate proposals.
    • Composition: The TDB committee had 12 members, largely from private equity and technology, with one non voting government representative.
    • Eligibility: Projects must have achieved at least Technology Readiness Level (TRL) 4, meaning laboratory validation is complete.
    • Selection Criteria: Scientific, technological, financial and commercial viability, with decisions taken by majority vote.

    What did the investigation reveal?

    • Conflict Links: 15 of 22 beneficiaries had investment ties with 7 committee members.
    • Funding Concentration: These firms received over Rs 1,377 crore of the total approved amount.
    • Chairman’s Role: Nine selected firms were linked to the committee chairman, who reportedly also held a personal stake in one beneficiary.
    • Committee’s Defence: Members stated that interests were disclosed and they recused themselves from related decisions.
    • Governance Concern: The episode has renewed demands for stronger safeguards in the use of public funds.

    Existing safeguards

    • Mandatory disclosure of financial interests by committee members.
    • Recusal from decisions involving associated companies.
    • Background verification of applicants by fund managers.
    • Expert driven selection to improve technical assessment.
    • However, only two SLFMs currently operate the scheme, concentrating decision making and highlighting the need for greater transparency.
