RBI Notifications

RBI’s Monetary Policy Committee (MPC) Decisions

Why in the News?

The RBI, in its Monetary Policy Committee (MPC) meeting, cut the Cash Reserve Ratio (CRR) by 1% to release ₹2.5 lakh crore into the banking system by November 2025.

Key Changes Announced:

  • Cash Reserve Ratio (CRR) reduced by 1% in four tranches, bringing it down to 3% by November 29, 2025.
  • This CRR cut will release ₹2.5 lakh crore liquidity into the banking system by December 2025.
  • Statutory Liquidity Ratio (SLR) remains unchanged at 18% of Net Demand and Time Liabilities (NDTL).

Key terms related to the MPC instruments:

Explanation
Cash Reserve Ratio (CRR)
  • CRR is the percentage of a bank’s total deposits that must be maintained as liquid cash with the RBI.
  • Banks cannot use this amount for lending or investment. No interest is earned on CRR.
  • It is used to control liquidity and inflation in the economy.
  • Increasing CRR reduces bank lending capacity; decreasing it increases liquidity.
  • Current CRR is 4.5% of Net Demand and Time Liabilities (NDTL).
Statutory Liquidity Ratio (SLR)
  • SLR is the minimum percentage of NDTL that banks must maintain in liquid form.
  • It includes cash, gold, or approved government securities, kept with the bank itself.
  • It helps ensure bank solvency and restricts excessive credit growth.
  • Raising SLR reduces funds available for lending; lowering it boosts credit and growth.
  • It also helps the government ensure demand for its securities.
Net Demand and Time Liabilities (NDTL)
  • It includes public deposits and balances held with other banks.
  • It excludes deposits the bank itself has with other banks.
  • Demand liabilities include current accounts and demand drafts.
  • Time liabilities include fixed deposits and recurring deposits.
  • CRR and SLR are calculated as a percentage of NDTL.
Repo Rate
  • The repo rate is the rate at which the RBI lends short-term funds to commercial banks against government securities.
  • Banks sell securities to RBI with an agreement to repurchase them later.
  • Lower repo rate makes borrowing cheaper and boosts liquidity.
  • Higher repo rate makes borrowing costlier, reducing liquidity.
  • It is a key monetary policy tool to regulate inflation and money supply.
Variable Rate Repo (VRR) Auction
  • VRR auction is a method where RBI conducts repo operations at variable interest rates.
  • Interest rate is determined through competitive bidding by banks.
  • It reflects real-time demand and supply of liquidity.
  • Enables more flexible and efficient liquidity management by RBI.
Standing Deposit Facility (SDF)
  • SDF allows banks to deposit surplus funds with the RBI without providing any collateral.
  • Banks earn interest at a rate set by the RBI.
  • It is used to absorb excess liquidity from the system.
  • Part of RBI’s liquidity management framework.
Weighted Average Call Rate (WACR)
  • WACR is the weighted average interest rate at which banks borrow and lend overnight funds in the interbank call money market.
  • It is an important indicator of short-term liquidity conditions.
  • RBI monitors WACR to guide monetary policy decisions.

 

[UPSC 2020] If the RBI decides to adopt an expansionist monetary policy, which of the following would it not do?

1. Cut and optimise the Statutory Liquidity Ratio.

2. Increase the Marginal Standing Facility Rate.

3. Cut the Bank Rate and Repo Rate.

Select the correct answer using the code given below:

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

Global Energy Investment Report, 2025

Why in the News?

China will lead global energy investments in 2025, making up over a quarter of total spending, says the International Energy Agency’s (IEA) 10th edition Global Energy Investment Report, 2025.

Back2Basics: International Energy Agency (IEA)

  • Establishment: The IEA was formed in 1974 under the Organization for Economic Cooperation and Development (OECD) in response to the 1973 oil crisis, with headquarters in Paris, France.
  • Membership: It has 31 member countries (e.g., US, UK, France, Japan) and 11 association countries like India, China, and Brazil.
  • India’s Role: India joined as an Association Country in 2017, gaining access to data-sharing, policy support, and technical cooperation.
  • Expanded Mission: The IEA now supports energy security, clean energy transitions, emissions tracking, and policy development.
  • Global Influence: Its major reports—World Energy Outlook, Net Zero by 2050, and Energy Technology Perspectives—guide governments and investors worldwide.

About the Global Energy Investment Report:

  • Origin and Purpose: Officially titled World Energy Investment Report, is the IEA’s flagship annual publication.
  • Published since 2016: To assess investment flows across the global energy system.
  • Scope of Coverage: It tracks investments in fossil fuels, renewables, electricity supply, critical minerals, energy efficiency, R&D, and innovation financing.
  • Strategic Value: The report helps determine if current investments support climate goals and universal energy access.

Global Energy Investment Report, 2025

Key Highlights from the 2025 Report:

  • China’s Role: China will account for over 25% of global energy investment, with over $625 billion in clean energy, though it also approved 100 GW of new coal plants in 2024.
  • Global Trends: Clean energy investment will hit $2.2 trillion, over twice the amount spent on fossil fuels, yet still falls short of COP28 targets.
  • Africa’s Investment Gap: Africa’s fossil fuel investment dropped from $125 billion to $54 billion, and it still receives only 2% of global clean energy funds, mainly due to debt burdens.
  • India’s Position: India’s renewables investment rose from $13 billion (2015) to $37 billion (2025), while fossil fuel investment also increased. However, grid and storage spending declined to $25 billion.
  • Financing Barriers: India’s high cost of capital—80% above advanced economies—limits clean energy growth. The “Baku to Belem Roadmap” seeks to mobilize $1.3 trillion by 2035 for such regions.
  • Global Mismatch: While $1 trillion is spent annually on power generation, only $400 billion goes to grid infrastructure, affecting distribution capacity.

Tiger Conservation Efforts – Project Tiger, etc.

State of Tigers Prey in India

Why in the News?

For the first time, India has conducted a detailed assessment of ungulate species (mammals with hoofs on their foot, like deer, pigs, antelopes, and bison), which are vital prey for tigers and important for forest ecosystems.

About Status of Tiger Prey in India:

  • The report titled “Status of Ungulates in Tiger Habitats of India” was released by the Wildlife Institute of India (WII) and the National Tiger Conservation Authority (NTCA), using data from the 2022 All-India Tiger Estimation.
  • This is the first national-level assessment of ungulates, the hoofed mammals like chital, sambar, gaur, wild pig, nilgai, which form the core prey base of tigers.
  • Ungulates are essential not only for tiger survival but also for maintaining healthy forest ecosystems, supporting biodiversity, and promoting soil and vegetation health.
  • The study stresses that tiger numbers alone are not enough; prey density and habitat quality must also be monitored to assess ecosystem health.
  • It establishes that 30 ungulates per sq km are needed to support 4 tigers per 100 sq km, but growth is constrained by territoriality, interspecies competition, and habitat fragmentation.

Key Highlights:

  • Prey Decline in East-Central India: Significant decline in Odisha, Jharkhand, and Chhattisgarh due to habitat loss, deforestation, urbanization, mining, subsistence hunting, civil unrest, and Left Wing Extremism.
  • Thriving Regions: Healthier prey populations in the Shivalik-Gangetic Plains (Uttarakhand, UP, Bihar), Madhya Pradesh, Maharashtra, the Western Ghats, and Northeast India.
  • Species Trends:
    • Chital is the most widespread and adaptable species.
    • Sambar and gaur remain stable in central and southern forests.
    • Hog deer and barasingha show sharp decline due to wetland degradation and habitat isolation.
  • Human-Wildlife Conflict:
    • In low-prey areas like Tadoba and Ratapani, tigers prey on livestock, increasing conflict.
    • Wild pigs and nilgai damage crops, leading to retaliatory killings and local resentment.
  • Conservation Measures:
    • On-site prey breeding in predator-proof enclosures
    • Forest restoration and better habitat connectivity
    • Focused protection of sanctuaries and buffer zones
    • Reducing habitat fragmentation caused by roads, railways, and power lines

About Tiger Conservation in India

  • Declared National Animal of India in 1972 by the Indian Board for Wildlife (IBWL).
  • Largest population in India; also found in Bangladesh, Nepal, Bhutan, China, and Myanmar. India harbours 75% of the world’s wild tigers.
  • Occupies habitats such as high mountains, mangrove swamps, grasslands, deciduous forests, evergreen, and shola forests.
  • Ecological Significance:
    • Flagship species: Essential for conservation efforts.
    • Umbrella species: Protecting tigers helps conserve other species.
  • Key driver of ecotourism and related industries.
  • Cultural & Spiritual Significance: Symbolizes power and strength.
  • Protection Status:
    • Indian Wildlife (Protection) Act, 1972: Schedule I.
    • IUCN Red List: Endangered.
    • CITES: Listed in Appendix I.
  • Project Tiger is a wildlife conservation initiative in India that was launched in 1973.

Global Geological And Climatic Events

Massive eruption of Italy’s Mount Etna

Why in the News?

Mount Etna, Europe’s largest active volcano, has erupted sending ash, smoke, and rock fragments several kilometres into the sky.

Why do Volcanoes Erupt?

  • Magma Formation: Deep within Earth, high temperature and pressure melt rocks into magma.
  • Gas Expansion: Magma contains gases like water vapor, CO, and SO. As magma rises, the pressure drops, allowing these gases to form bubbles, increasing internal pressure.
  • Crustal Weaknesses: At tectonic boundaries or mantle plumes, cracks and faults in Earth’s crust provide pathways for magma to escape.
  • Eruption Mechanism:
    • As pressure builds, magma is pushed upwards.
    • If blocked, the gas expansion can explode through the crust, ejecting lava, ash, and gases.
  • Signals: If magma flow is suddenly stopped by solid rock, it may create low-frequency seismic waves (pre-eruption tremors).

Next Census to conclude by March 2027

About Mount Etna:

  • Location: Situated on the east coast of Sicily, Italy, near the city of Catania.
  • Type: Mount Etna is a stratovolcano (also called a composite volcano), which is formed from layers of hardened lava, volcanic ash, and rocks.
  • Height: It stands at approximately 3,300 meters, making it the tallest volcano in Europe south of the Alps.
  • Recognition: Declared a UNESCO World Heritage Site in 2013, with documented volcanic activity for at least 2,700 years.
  • Eruption Record: Etna is almost constantly active. Notable eruptions have occurred in 1400 B.C., 1669, 2001, 2018, 2021, 2024, and 2025.
  • Volcanic Activity Style: Known for Strombolian and effusive eruptions, with occasional Plinian eruptions (rare and more explosive).

Reasons Behind the June 2025 Eruption:

  • Nature of Eruption: The eruption is classified as either Strombolian or possibly Plinian, depending on interpretation:
    • Strombolian Eruption: Characterized by moderate explosive bursts, caused by gas bubbles in magma suddenly bursting at the surface.
    • Plinian Eruption: Some volcanologists suggest this classification due to the large ash column that may have reached the stratosphere.
  • Eruption Trigger: The eruption likely began due to pressure buildup from gas within the magma chamber, leading to collapse of the southeast crater and lava flows.
[UPSC 2024] Consider the following:

1. Pyroclastic debris

2. Ash and dust

3. Nitrogen compounds

4. Sulphur compounds

How many of the above are products of volcanic eruptions?

Options: (a) Only one (b) Only two (c) Only three (d) Only four*

Air Pollution

Rising ‘Black Carbon’ heating Himalayan Snow: Study

Why in the News?

A recent study by the think-tank Climate Trends has revealed that levels of black carbon in the Himalayas have been rising steadily over the past two decades.

About Black Carbon (BC):

  • What is it: Black carbon is a fine particulate pollutant formed from the incomplete combustion of biomass and fossil fuels.
  • Impact: It is a short-lived climate pollutant and the second-largest contributor to global warming after carbon dioxide.
  • Lifespan: Unlike CO₂, black carbon stays in the atmosphere for short periods and can be quickly reduced if emissions stop.
  • Warming Mechanism: As an aerosol, it absorbs sunlight, heats the atmosphere, and reduces albedo when deposited on snow and ice, leading to faster melting.
  • Health Effects: Exposure increases the risk of heart disease, birth complications, and premature death.
  • Major Sources in India:
    • Residential Biomass Burning: Accounts for 47% of BC emissions, including cow dung and straw burning.
    • Industries and Vehicles: Industries contribute 22%, while diesel vehicles add 17%.
    • Other Sources: Open burning contributes 12%, and other minor sources 2%.
    • High-Emission States: Madhya Pradesh and Maharashtra are major emitters due to agricultural and forest fires.
    • Biofuel Usage: Alone contributes nearly 42% of India’s total BC emissions.

Key Findings from the Study (2000–2023):

  • Snow Temperature Rise: Himalayan snow surface temperature rose from -11.27°C to -7.13°C over two decades.
  • Regional Trends: The Eastern Himalayas were warmest, followed by the Central and Western regions.
  • BC Influence: Deposits of black carbon lower snow reflectivity, increase heat absorption, and accelerate glacier melt.
  • Population Risk: Glacier loss threatens the freshwater supply for nearly 2 billion people downstream.
  • Increase in Snow Depth: Despite warming, average snow depth rose from 0.059 m to 0.117 m.
  • Reasons: This is due to more snowfall, changing precipitation, and wind redistribution.
  • Regional Comparison: The Western Himalayas showed highest snow depth, linked to elevation and winter storms, while the Eastern and Central Himalayas had less snow due to proximity to BC sources.
[UPSC 2017] Consider the following statements:

1. Climate and Clean Air Coalition (CCAC) to Reduce Short-Lived Climate Pollutants is a unique initiative of G20 group of countries;

2. The CCAC focuses on methane, black carbon and hydrofluorocarbons.

IISc develops Nanozyme to prevent Abnormal Blood Clotting

Why in the News?

Researchers at the Indian Institute of Science (IISc) have created an artificial metal-based nanozyme that can help prevent dangerous blood clotting, especially in conditions like pulmonary thromboembolism (PTE) and COVID-19.

What is Blood Clotting?

  • About: When we get a cut or injury, our body quickly stops the bleeding by forming a blood clot. This is done by special blood cells called platelets that stick together and seal the wound.
  • Control mechanism: This natural process is called blood clotting or haemostasis and is controlled by certain chemicals in our body like collagen and thrombin.
  • Post covid issues: But in some illnesses like pulmonary thromboembolism (PTE) or COVID-19, the body sends too many signals to make clots, even when there is no injury.
  • Oxidative Stress: This creates a problem called oxidative stress, where harmful molecules called Reactive Oxygen Species (ROS) build up in the blood. These ROS molecules over-activate the platelets, causing them to make too many clots inside blood vessels.
  • Hazards: This can block blood flow, leading to serious health issues like heart attacks, strokes, or lung problems. This condition is called thrombosis, and it can be life-threatening.

Vanadium-Based Nanozyme and Its Features:

  • Purpose and Design: Scientists at IISc developed vanadium-based nanozymes to mimic natural antioxidant enzymes that reduce ROS levels.
  • How they work: The nanozymes control oxidative stress by copying glutathione peroxidase, an enzyme that removes ROS and protects platelets.
  • Optimal Structure: Spherical-shaped vanadium pentoxide (VO) nanozymes were found to be the most effective.
  • Test Results in Mice: These nanozymes reduced blood clots and improved survival in PTE-affected mice with no toxicity signs over five days.
  • Next Steps: Scientists plan to test the nanozyme in ischemic stroke and are optimistic about human clinical trials after promising lab results with human platelets.
[UPSC 2015] With reference to the use of nano-technology in health sector, consider the following statements:

1. Targeted drug delivery is made possible by nanotechnology.

2. Nanotechnology can largely contribute to gene therapy.

Judicial Appointments Conundrum Pre-NJAC Verdict

Appointment and Removal of High Court Judges

Why in the News?

The Centre will bring a motion of removal against a Judge of the Allahabad High Court and has initiated the process of building an all-party consensus for this action.

Qualifications of Judges of High Court:

  • Article 217(2) of the Constitution states that a person is qualified if:
    • They have held judicial office in India for at least 10 years, or
    • Have been an advocate in a High Court (or more than one in succession) for at least 10 years.
  • Tenure: As per Article 217(1), a High Court judge holds office till the age of 62 years.
  • Disputes over Age: Under Article 217(3), if a question arises regarding a judge’s age, the President, in consultation with the CJI, makes the final decision.

Appointment Process of High Court Judges:

  • Constitutional Basis: The Article 217 of the Constitution provides that High Court judges are appointed by the President of India after consultation with the Chief Justice of India (CJI), the Governor of the state, and, in the case of judges (not Chief Justices), the Chief Justice of the High Court concerned.
  • Role of the Collegium System: The Collegium, comprising the CJI and 2 senior-most judges of the Supreme Court, plays a key role in recommending names for appointments. It ensures collaborative decision-making and maintains the independence of the judiciary.
  • Procedure:
    1. The Chief Justice of the High Court initiates the recommendation.
    2. The proposal is forwarded to the Chief Minister, who advises the Governor.
    3. The Governor sends it to the Union Law Minister, who places it before the Prime Minister, and then the President for final approval.
  • Policy for Chief Justices: To prevent local bias, Chief Justices of High Courts are generally appointed from outside the state.
  • Appointments and Transfers: The CJI and senior judges of the Supreme Court also decide on transfers of High Court judges, ensuring judicial autonomy and minimizing executive influence.

Removal:

  • Process: Judges of the High Court (and Supreme Court) can only be removed through removal, not by executive action.
    • Requires a motion signed by at least 100 Lok Sabha MPs or 50 Rajya Sabha MPs.
    • The motion is examined by a three-member committee.
    • If the committee finds grounds, the motion is debated and must be passed by a two-thirds majority in both Houses of Parliament.
  • Legal Framework: The Judges (Inquiry) Act, 1968 outlines the detailed procedure for investigating and acting upon misconduct by judges.
  • In-House Inquiry Mechanism: For internal disciplinary matters:
    • The CJI may order a preliminary inquiry based on credible complaints.
    • A three-judge panel is constituted if allegations are serious.
    • If the committee confirms misconduct, the CJI may ask the judge to resign.
    • If the judge refuses, the judicial work is withdrawn, and removal may be considered.

Historical Removal Efforts:

  • No judge has been impeached in India, though attempts have been made, including the failed motions against Justice V Ramaswami (1993) and Justice Soumitra Sen (2011).
  • Justice V Ramaswami (1993): Faced removal for financial misconduct, but the motion failed in the Lok Sabha.
  • Justice Soumitra Sen (2011): Resigned after removal proceedings for misappropriating funds.
  • Justice K Veeraswamy: Chief Justice of Madras HC, investigated for corruption but challenged the investigation. The case remained unresolved until his death in 2010.
  • Justice Shamit Mukherjee (2003), Justice Nirmal Yadav (2008), and Justice SN Shukla (2017): Faced criminal charges for corruption after in-house inquiries found substantial evidence against them.

 

[UPSC 2007] Consider the following statements:

1. The mode of removal of a Judge of a High Court in India is the same as that of the removal of a Judge of the Supreme Court. 2. After retirement from office, a permanent Judge of a High Court cannot plead or act in any court or before any authority in India.

Which of the statements given above is/are correct?

Options: (a) 1 only*  (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

Judicial Reforms

Making a Law cannot amount to Contempt of Court: Supreme Court

Why in the News?

The Hon’ble Supreme Court has ruled that any law passed by Parliament or a State Legislature cannot be considered an act of contempt of court.

Supreme Court’s Verdict on the Issue:

  • Context: The Court heard a 2012 contempt plea, alleging that the Chhattisgarh government violated its 2011 ruling against supporting Salwa Judum and arming tribals as SPOs.
  • Disputed Law: Petitioners argued the Chhattisgarh Auxiliary Armed Police Force Act, 2011 violated the earlier ruling.
  • Court’s Clarification: Passing a new law is within the plenary powers of legislatures and cannot be treated as contempt unless declared unconstitutional.
  • Proper Remedy: The correct approach is to challenge the law’s validity, not to file for contempt.
  • Separation of Powers: The Court upheld that legislature can modify or override judgments through new laws, if they respect constitutional boundaries.

About Contempt of Court:

  • Purpose: Contempt of court refers to actions or behaviors that are disrespectful to, or that obstruct or interfere with, the administration of justice by a court. It protects the authority and dignity of the judiciary from acts that obstruct or interfere with justice.
  • Constitutional Basis:
    • Article 129 allows the Supreme Court to punish for its own contempt.
    • Article 215 grants the same power to High Courts.
    • Article 19(2) permits reasonable speech restrictions for contempt cases.
  • Legal Definition: The Contempt of Courts Act, 1971 defines contempt; the 2006 amendment allows truth and good faith as defences.
  • Types:
    • Civil Contempt is the wilful disobedience of court orders.
    • Criminal Contempt involves actions that scandalise the court, interfere with proceedings, or obstruct justice.
  • Punishment: Offenders may face up to 6 months imprisonment, or a ₹2,000 fine, or both.
  • What Is Not Contempt: Fair reporting and genuine criticism of judgments after disposal are not considered contempt.

National Polio Surveillance Network (NPSN)

Why in the News?

The Indian government has proposed a phased winding down of the National Polio Surveillance Network (NPSN), a WHO-established network critical to tracking and eliminating polio in India.

About National Polio Surveillance Network (NPSN):

  • Launch : The NPSN was established in 1997 as a collaboration between the World Health Organization (WHO) and the Ministry of Health and Family Welfare (MoHFW), Government of India.
  • Objective: Its main goal is to detect and monitor the poliovirus in India to enable quick response and containment.
  • Operational Structure: The network functions under the National Polio Surveillance Project (NPSP) and includes over 200 field surveillance units across the country.
  • Methodology: The core method is Acute Flaccid Paralysis (AFP) surveillance, which tracks sudden paralysis in children under 15 — a key indicator of polio.
  • Environmental Surveillance: The NPSN also tests sewage and water samples to detect silent circulation of the virus.
  • Laboratory Support: A network of WHO-accredited laboratories confirms virus presence through testing of stool and water samples.
  • Rapid Response: Every suspected case is quickly investigated, and public health teams are deployed for control and containment.
  • Expanded Role: Over time, NPSN has also supported surveillance for measles, rubella, DPT, and helped train health workers on new vaccines.

Polio and Its Eradication in India:

  • About: Polio is a highly infectious viral disease primarily affecting children under 5, potentially causing paralysis or death.
  • Transmission: The disease spreads via the faecal-oral route, mostly through contaminated water or food.
  • Types of Polioviruses:
    • WPV1 still exists in Pakistan and Afghanistan.
    • WPV2 and WPV3 have been eradicated globally.
  • Infection Mechanism: Once inside the body, the virus multiplies in the intestines and may attack the nervous system, causing permanent paralysis.
  • Prevention through Vaccination:
    • Oral Polio Vaccine (OPV) is given at birth, 6, 10, and 14 weeks, with a booster at 16–24 months.
    • Injectable Polio Vaccine (IPV) is administered with the third DPT dose under the Universal Immunization Programme (UIP).
  • Pulse Polio Campaign (1995): India launched the Pulse Polio Immunization Campaign, providing oral polio drops to all children under 5.
  • Eradication Milestones: The last wild polio case in India was reported in 2011, and in 2014, WHO officially declared India polio-free.
  • Role of NPSN: The success was enabled by strong surveillance, mass immunization, and dedicated work by NPSN and its partners.
[UPSC 2016] ‘Mission Indradhanush’ launched by the Government of India pertains to:

(a) Immunization of children and pregnant women*

(b) Construction of smart cities across the country

(c) India’s own search for the Earth-like planets in outer space

Thermophilic Bacteria in Rajgir Hot Spring could help fight Deadly Infections

Why in the News?

Researchers from the Vellore Institute of Technology (VIT) have discovered antibiotic-producing bacteria in the Rajgir hot spring in Nalanda, Bihar.

What are Thermophilic Bacteria?

  • About: Thermophilic bacteria, or thermophiles (meaning “heat lovers”), are microorganisms that thrive in high-temperature environments ranging from 45°C to 70°C.
  • Adaptation: These temperatures can cause third-degree burns in humans, but thermophiles are biologically adapted to survive and grow in such conditions.
  • Habitats: They are commonly found in hot springs, deep-sea hydrothermal vents, and compost piles, which are mineral-rich and have low microbial competition.
  • Advantages: Some thermophiles produce potent antibiotics to outcompete other microbes and dominate their niche.
  • Global Example: Thermophiles from hot springs in Saudi Arabia have shown antibacterial activity against gram-positive pathogens.

Key Findings from India:

  • Sampling Challenge: Samples were collected from water and soil at 43°C–45°C, making fieldwork difficult.
  • Microbial Analysis: In the sample, Actinobacteria made up 40–43% of the microbial population, double the typical amount in hot springs.
  • Significance: Actinobacteria are well known for producing key antibiotics like streptomycin and tetracycline.
  • AMR Context: The findings are crucial in the fight against antimicrobial resistance (AMR), which could cost $1 trillion globally by 2050, according to the WHO.
  • Antibiotic Potential:
    • Lab Testing: Seven Actinobacteria strains were found to inhibit pathogens such as E. coli, Salmonella, Klebsiella, Pseudomonas, and Staphylococcus aureus.
    • Compound Discovery: Scientists identified diethyl phthalate using GC-MS, which showed effectiveness against Listeria monocytogenes, a deadly foodborne pathogen.
    • Future Scope: The compound has potential for antibiotic development, but not all thermophiles produce antibiotics, so screening is essential.
  • Uses:
    • Industrial Use: The enzyme Taq polymerase, used in PCR tests (including during COVID-19), is derived from a thermophile called Thermus aquaticus.
    • Agricultural Use: A 2018 BHU study showed thermophiles from Chumathang hot springs (Leh) promote plant growth, revealing wider industrial and ecological value.
[UPSC 2023] Consider the following statements:

1. Some microorganisms can grow in environments with temperature above the boiling point of water.

2. Some microorganisms can grow in environments with temperature below the freezing point of water.

3. Some microorganisms can grow in highly acidic environment with a pH below 3. How many of the above statements are correct?

Options: (a) Only one (b) Only two (c) Only three* (d) All four

Air Pollution

Expert Committee recommends ending mandatory Flue Gas Desulphurisation (FGD) 

Why in the News?

A high-powered committee chaired by Principal Scientific Advisor (PSA) Ajay Sood has proposed that India should discontinue the mandatory use of Flue Gas Desulphurisation (FGD) units in most coal-fired Thermal Power Plants (TPPs).

Why mandatory FGDs are opposed?

  • Low SO Levels: India’s SO₂ levels (10–20 µg/m³) are already below the permissible limit of 80 µg/m³.
  • Low Sulphur Coal: Indian coal naturally has low sulphur content.
  • Minimal Impact: Studies show no major air quality difference between plants with and without FGDs.
  • Limited PM Reduction: FGDs have minimal effect on particulate matter levels.
  • Environmental Trade-Offs:
    • CO Increase: Installing FGDs would add 69 million tonnes of CO₂ emissions (2025–2030).
    • SO Reduction: Emissions would fall by 17 million tonnes, but the climate cost outweighs the benefit.

About Flue Gas Desulphurisation (FGD):

  • Purpose: FGD is a technology used to remove sulphur dioxide (SO) from flue gases produced by burning coal and oil, especially in thermal power plants.
  • Environmental Benefit: It helps prevent acid rain, which harms crops, buildings, soils, and aquatic ecosystems.
  • Chemicals Used: Common absorbents include limestone (CaCO), lime (CaO), and ammonia (NH).
  • Types of Systems:
    1. Dry Sorbent Injection: Cost-effective, but less efficient.
    2. Wet Limestone-Based: Effective and used in large plants, produces gypsum.
    3. Seawater-Based: Uses alkaline seawater, ideal for coastal areas.

FGD Mandate in India:

  • Current Status: FGD units are being installed in 537 coal-based thermal power units, but 92% of India’s 600 plants still lack them.
  • Committee Recommendation: An expert panel advised exempting 80% of plants from FGD requirements due to feasibility issues.
  • Implementation Barriers: Limited vendors available; High costs and risk of increased electricity tariffs.
[UPSC 2023] Consider the following:

1. Carbon monoxide 2. Nitrogen oxide 3. Ozone 4. Sulphur dioxide Excess of which of the above in the environment is/are cause(s) of acid rain?

Options: (a) 1, 2 and 3 (b) 2 and 4 only* (c) 4 only (d) 1, 3 and 4

‘Bharat Gen’ AI-based multimodal LLM for Indian languages launched

Why in the News?

Union Minister of State for Science & Technology has launched ‘Bharat Gen’, India’s first indigenously developed AI-based Large Language Model (LLM) tailored for Indian languages.

About Bharat Gen:

  • What is it: Bharat Gen is India’s first homegrown AI-based multimodal large language model (LLM) supporting 22 Indian languages.
  • Developed By: Created under the National Mission on Interdisciplinary Cyber-Physical Systems (NM-ICPS) and implemented by the TIH Foundation for IoT and IoE at IIT Bombay.
  • Key Features:
    • Understands text, speech, and image inputs.
    • Works across India’s diverse languages and cultures.
    • Designed to be ethical, inclusive, and culturally rooted.
  • Support and Collaboration: Backed by the Department of Science and Technology (DST) and developed in collaboration with top academic and AI institutions.
  • Bharat Data Sagar: A national effort to collect language data for lesser-known Indian languages to train future AI tools.
  • Real-World Use: In places like Udhampur, an AI doctor powered by Bharat Gen is helping patients in their native language.

What are Large Language Models (LLMs)?

  • LLMs are computer programs that can read, understand, and write language like humans. They can answer questions, explain topics, write stories, translate languages, and more.
  • Why are they called “large”?
    • They are trained using a huge amount of text from books, websites, newspapers, etc.
    • They also have billions of settings (called parameters) that help them understand words and sentences better.
  • How do they work?
    • LLMs break your sentence into small parts (called tokens).
    • They guess the next word in the sentence, one by one, using what they’ve learned.
    • This is how they create full and meaningful answers.
  • How are they trained?
    1. Step 1 – Pre-training: The LLM reads lots of text and learns how language works.
    2. Step 2 – Fine-tuning: It is then taught how to do specific tasks like summarising or translating.
    3. Step 3 – Human Help: People check the answers and give feedback, so the LLM learns to give better responses.
  • How do LLMs understand language so well? They use a special model called a transformer, which has tools to:
    • Focus on important words in a sentence (self-attention).
    • Understand the order of words (positional encoding).
    • Learn patterns and meaning using neural networks (like a brain made of computer code).

 

[UPSC 2020] With the present state of development, Artificial Intelligence can effectively do which of the following?
