Legionnaire’s Disease

Legionnaire’s Disease

Legionnaires' Disease Latest News

A Legionnaires’ disease outbreak has prompted a health alert in Sydney’s central business district recently, with authorities urging people to remain vigilant for symptoms.

About Legionnaires' Disease

  • It is a severe form of a lung infection (pneumonia) caused by a bacterium known as legionella.
  • The disease got its name when a group of people at an American Legion convention became ill with this type of pneumonia in 1976.

Legionnaires' Disease Transmission

  • Legionella is found naturally in freshwater, such as lakes and rivers. It can also be found in soil. 
  • Most people who catch Legionnaires’ disease breathe in the bacteria from water or soil. 
  • You usually can’t get infected by drinking water that contains the bacteria unless you aspirate it (accidentally breathe the water into your lungs).
  • It is not contagious, meaning it is not spread from person to person.
  • Older adults, people with weakened immune systems, and people who smoke have a higher risk of getting Legionnaires’ disease.

Legionnaires' Disease Symptoms

  • Legionnaires’ disease causes pneumonia-like symptoms that start two to 14 days after exposure to Legionella. 
  • Patients usually present with fever, cough, shortness of breath, tiredness, headache, muscle pain, and may have gastrointestinal symptoms such as abdominal pain and diarrhoea. 
  • In severe cases, neurological symptoms (e.g., confusion) and respiratory failure may occur, and some cases may result in death.

Legionnaires' Disease Treatment

  • Treating right away with antibiotics most often cures Legionnaires’ disease.
  • But some people still have problems after treatment.
  • Currently, there is no vaccine available for LD.

Gas Hydrates

Gas Hydrates

Gas Hydrates Latest News

A reserve of natural gas bubbling from a cage of ice discovered on the ocean floor to the west of Greenland may be the deepest gas hydrate cold seep on record, and it happens to be teeming with animal life.

About Gas Hydrates

  • Gas hydrates are ice-like crystalline structures that form when a low-density gas, like methane, ethane, or carbon dioxide, combines but does not chemically bond with water and freezes into a solid under low temperature and moderate pressure conditions. 
  • Most gas hydrates are formed from methane (CH4), which has led to the terms “gas hydrate” and “methane hydrate” often being used interchangeably.
  • They are classified as clathrates, compounds formed by the inclusion of one molecule within cavities in the crystal lattice of another.  
    • A unique property of clathrates is the absence of chemical bonding, which makes it possible to separate them relatively easily. 
  • For example, when methane hydrates are warmed or depressurized, it will revert back to water and natural gas.
  • On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost. 
  • They are also speculated to form on other planets.
  • Gas Hydrates are important for a variety of reasons:
    • Gas hydrate deposits may contain roughly twice the carbon contained in all reserves of coal, oil, and conventional natural gas combined, making them a potentially valuable energy resource.
    • Their decomposition can release large amounts of methane, which is a greenhouse gas that could impact Earth’s climate.
    • Sudden release of pressurized methane gas may cause submarine landslides, which in turn can trigger tsunamis.
    • Gas hydrates in the ocean can be associated with unusual and possibly unique biological communities that use hydrocarbons or hydrogen sulfide for carbon and energy via a process known as chemosynthesis.

Gas Hydrates FAQs

Q1: What are gas hydrates?

Ans: Gas hydrate is a crystalline solid, its building blocks consist of a gas molecule surrounded by a cage of water molecules.

Q2: Which gas is most commonly involved in the formation of gas hydrates?

Ans: Methane is the most common gas involved in the formation of gas hydrates.

Q3: Where do gas hydrates occur naturally on Earth?

Ans: Gas hydrates occur naturally in some marine sediments and within or beneath permafrost regions.

Q4: Why are gas hydrates considered a potential energy resource?

Ans: Because gas hydrate deposits may contain roughly twice the carbon found in all reserves of coal, oil, and conventional natural gas combined.

Q5: How can gas hydrates influence Earth’s climate?

Ans: Gas hydrates can influence the climate because their decomposition releases methane, a potent greenhouse gas.

India’s Clean Energy Transition - Manufacturing Push, Market Paradoxes and Structural Bottlenecks

Context

  • India is accelerating its clean energy transition to meet climate commitments (NDCs), reduce import dependence, and position itself as a global renewable energy and green hydrogen hub.
  • Recent gains in domestic solar manufacturing and clean energy investments signal momentum, but deep structural challenges persist across manufacturing, finance, grid infrastructure, and emerging technologies.

Key Developments

  • Solar manufacturing - From import dependence to domestic capacity

    • For years, India relied heavily on Chinese solar imports. In 2024, domestic firms added 25.3 GW of module manufacturing capacity, nearly doubling national capacity.
    • The Production Linked Incentive (PLI) scheme catalysed private investment, and signalled India’s intent to move up the global value chain.
    • Adoption of TOPCon (Tunnel Oxide Passivated Contact) cells reflects a shift toward higher-efficiency, higher-value innovation.
  • Structural contradictions in solar supply chain

    • Despite capacity expansion, India imported about 66 GW of solar modules and cells in 2024, while exports marginally declined.
    • Upstream integration is weak - only 2 GW wafer capacity commissioned, compared to nearly 80 GW downstream module capacity.
    • Absence of polysilicon and wafer manufacturing risks dependency substitution, not elimination, highlighting the missing middle of manufacturing.
  • Clean energy investment boom with financial stress

    • $3.4 billion FDI attracted in the first nine months of FY2025 (over 80% of power sector inflows).
    • Competitive auctions pushed tariffs to record lows, making renewables among the cheapest electricity sources
    • However, DISCOM financial distress (unpaid dues), post-auction contract renegotiations in some states, undermine contractual sanctity and investor confidence.
  • Grid and transmission constraints

    • Nearly 60 GW of renewable capacity is stranded due to inadequate transmission infrastructure.
    • Issues include - Grid congestion, curtailment without compensation, etc.
    • Consequences:
      • Difficulty in financial modelling.
      • Higher risk premiums.
      • India’s renewable financing costs are about 80% higher than advanced economies.
    • National Green Hydrogen Mission (NGHM) - Strategic promise, economic hurdles:
      • India currently consumes about 5 million tonnes of grey hydrogen.
      • Target under NGHM: 5 million metric tonnes of green hydrogen annually by 2030. Pilot projects in steel, refining, transport (hard-to-abate sectors).
      • Challenges:
        • Current costs of $4.1–$5.0 per kg is projected to be around $2.4 per kg by 2030, which remains uncompetitive without subsidies, carbon pricing, and regulatory mandates.
        • Infrastructure gaps in storage, transport, and end-use.
        • Chicken-and-egg problem - No demand without supply certainty, no supply without assured demand.

Challenges and Way Ahead

  • Weak upstream solar manufacturing (polysilicon, wafers): Promote end-to-end solar value chain integration.
  • Regulatory uncertainty and contract renegotiation: Ensure contractual sanctity to protect investor confidence.
  • Transmission bottlenecks and uncompensated curtailment: Synchronise transmission expansion with renewable capacity addition. Establish clear curtailment compensation frameworks.
  • Green hydrogen’s cost and demand uncertainty: For green hydrogen -
    • Adopt realistic timelines.
    • Create demand through mandates, incentives, and carbon markets.
    • Invest in shared infrastructure for storage and transport.

Conclusion

  • India’s clean energy transition reflects both ambition and complexity.
  • While manufacturing gains, low tariffs, and green hydrogen vision signal leadership potential, unresolved structural bottlenecks threaten sustainability.
  • Addressing grid, financial, and supply-chain weaknesses—while safeguarding policy credibility—will determine whether India emerges merely as a large clean energy market or as a global model for energy transition in the developing world.

India’s Clean Energy Transition FAQs

Q1. How has the PLI scheme contributed to India’s solar manufacturing ecosystem?

Ans. It has catalysed private investment, doubled domestic module capacity in 2024, etc.

Q2. Why does India’s solar manufacturing expansion still risk continued import dependence?

Ans. The absence of upstream manufacturing in polysilicon and wafers has created a value-chain imbalance.

Q3. What are the major financial and regulatory risks affecting India’s renewable energy sector?

Ans. DISCOM payment delays, post-auction contract renegotiations, and regulatory uncertainty undermine contractual sanctity.

Q4. How do transmission constraints impact renewable energy deployment in India?

Ans. Inadequate transmission infrastructure leads to curtailment without compensation, stranded capacity, etc.

Q5. What are the key challenges to the commercial viability of green hydrogen under India’s National Green Hydrogen Mission?

Ans. High production costs, underdeveloped infrastructure, and a demand–supply coordination gap necessitate subsidies.

Alleged Fake Rabies Vaccines: A Test for India’s Health Governance

Fake Rabies Vaccine

Fake Rabies Vaccine Latest News

  • Health authorities in Australia have advised citizens vaccinated for rabies in India to check whether they require replacement doses, following concerns about counterfeit rabies vaccines.
  • Similar advisories have been issued by the United Kingdom and the United States.
  • This episode highlights critical issues of drug supply chain integrity, regulatory enforcement, and public confidence in vaccines—especially significant for India, which bears a high rabies burden and plays a key role in global vaccine supply.

Rabies: Transmission and Prevention

  • Rabies is a viral infection transmitted through the saliva of infected animals. 
  • Human infection can occur through bites, scratches, or saliva contact with open wounds, commonly involving dogs, cats, monkeys, and bats. 
  • Symptoms range from fever, headache, and nausea to excessive salivation, hydrophobia (fear of water), hallucinations, and partial paralysis.
  • Importantly, rabies is preventable through timely post-exposure vaccination, which is why prompt medical treatment after animal exposure is essential.

India’s Rabies Burden

  • According to India’s National Rabies Control Programme, 6,644 clinically suspected human rabies cases and deaths were reported between 2012 and 2022, though this is believed to be an under-estimate. 
  • The World Health Organisation estimates 18,000–20,000 rabies deaths annually worldwide, with one-third to two-thirds occurring in children under 15 years.
  • India alone accounts for nearly 36% of global rabies deaths, highlighting the public health significance of vaccine safety and regulatory oversight.

Background: Concerns Over Abhayrab Vaccine

  • Health authorities in Australia, the UK, and the US have issued advisories urging citizens who received rabies vaccinations in India to verify whether they require replacement doses. 
  • The alerts point to possible circulation of counterfeit rabies vaccines in India since 2023.
  • The advisories stem from concerns that fake batches of Abhayrab, a rabies vaccine manufactured by the Human Biologicals Institute (a key division of PSU Indian Immunologicals), may be in circulation. 
  • The issue has triggered international alarm because rabies is almost 100% fatal once symptoms appear, making vaccine efficacy critical.

Company’s Response and Identification of Counterfeit Batch

  • Indian Immunologicals Limited (IIL) stated that in January 2025, it detected one counterfeit batch (#KA24014) with altered packaging.
  • The company informed Indian regulators and law enforcement immediately.
  • It maintains that no other counterfeit batches have been found.

Nature of the Counterfeit: Packaging Diversion, Not Fake Vaccine

  • Investigations revealed that:
    • Counterfeit products were detected in Delhi, Mumbai, Agra, Lucknow, Kanpur, and Patna.
    • Raids were conducted in Delhi, Mumbai, and Agra.
    • Tests conducted at the Central Drug Testing Laboratory, Kasauli, found the seized vaccines to contain the genuine product.
  • Experts clarified that the issue involved tampered outer packaging, allegedly used to divert government-supplied vaccines into the open market, rather than fake or substandard vaccine contents.

Why Abhayrab Is Central to the Concern

  • Abhayrab is among the most widely used rabies vaccines in India, holding around 40% market share.
  • IIL is the largest rabies vaccine producer globally, supplying vaccines for over 25 years.
  • Company officials warned that international advisories could fuel vaccine hesitancy, particularly in rural areas where Abhayrab may be the only available option.

Expert Reassurance on Public Health Impact

  • Experts in India sought to allay fears:
    • In India, patients usually receive five doses of rabies vaccine after an animal bite.
    • Even if one dose were ineffective, protection is likely ensured through remaining doses and rabies immunoglobulin.

WHO-Recommended Vaccination Protocol

  • As per World Health Organisation guidelines:
  • Unimmunised persons: At least three intramuscular doses or Two intradermal doses, plus immunoglobulin on day zero.
  • Previously immunised persons: Only two booster doses are required.

Recent Rabies Cases and Vaccine Failure Concerns

  • In Kerala, a spike in rabies deaths was reported in 2022, raising public concern as several deceased individuals had reportedly received rabies vaccines. 
  • This led to suspicions of vaccine failure or ineffective vaccines.

Findings of the Union Health Ministry Committee

  • A committee constituted by the Union Health Ministry investigated the cases and ruled out vaccine failure as the primary cause. 
  • It concluded that deaths occurred due to:
    • Improper wound washing after animal bites
    • Non-administration of rabies immunoglobulin in Category 3 bites
      • Category 3 bites include multiple bites or scratches breaking the skin, or situations where broken skin is licked by an animal, which carry the highest risk of infection.
  • The committee highlighted limited availability of rabies immunoglobulin and vaccines as a major systemic challenge, which compromised timely and complete post-exposure prophylaxis.

Aravalli Hills and Environmental Protection – Explained

Aravalli Hills

Aravalli Hills Latest News

  • The Supreme Court has paused its earlier judgment accepting a restrictive definition of the Aravalli Hills and has proposed a re-examination through a high-powered expert committee.

About the Aravalli Mountain Range

  • The Aravalli Mountain Range is one of the oldest surviving fold mountain systems in the world, with geological origins dating back nearly 1.5 billion years. 
  • Stretching over 690 km, the range runs from Gujarat through Rajasthan and Haryana to Delhi, forming a crucial natural barrier in north-western India.
  • Ecologically, the Aravallis play a vital role in:
    • Preventing the eastward expansion of the Thar Desert
    • Regulating regional climate and rainfall patterns
    • Recharging groundwater aquifers
    • Acting as a green buffer against air pollution, particularly for the Delhi-NCR region
  • The hills host tropical dry deciduous forests, support diverse flora and fauna, and sustain rural livelihoods. 
  • Despite their importance, the Aravallis have faced severe degradation due to mining, urbanisation, and infrastructure expansion, making legal and policy protection critical.
  • Over the years, multiple court orders and expert committees have attempted to define and protect the Aravallis, but ambiguities in their legal definition have remained a major challenge.

Legal Background to the Aravalli Definition Issue

  • Environmental protection of the Aravallis has largely evolved through judicial interventions rather than a single comprehensive statute. Courts have relied on:
  • However, the absence of a scientifically precise and uniform definition of what constitutes the Aravalli range has led to disputes over which areas qualify for environmental protection.
  • In November 2025, the Supreme Court upheld a government expert panel’s definition that restricted the Aravallis to:
    • Hills with an elevation of 100 metres or more
    • Hill clusters, slopes, and hillocks located within 500 metres of each other
    • This definition significantly narrowed the geographical scope of the protected area.

News Summary

  • In December 2025, the Supreme Court kept its own November judgment in abeyance, citing serious environmental and regulatory concerns. Key developments include:
    • The Court directed that no irreversible administrative or ecological actions should be taken based on the restrictive definition until further review.
    • Fresh or renewed mining leases in the Aravalli region were prohibited without prior approval of the apex court.
    • Widespread public concern was noted that the 100-metre elevation rule could exclude a large number of ecologically significant hills, particularly in Rajasthan, Haryana, Uttar Pradesh, and Delhi.
    • The Court observed that if lower hill ranges were excluded, it could create a “significant regulatory lacuna”, enabling unregulated mining and environmental degradation.
  • The Bench proposed constituting a high-powered expert committee to:
    • Reassess whether “regulated” or “sustainable” mining in newly excluded areas could still harm ecological integrity
    • Evaluate the short-term and long-term environmental impacts of the restrictive definition
    • Examine whether the 500-metre clustering rule creates a structural paradox, where ecologically contiguous hills remain unprotected due to technical gaps
  • The Court emphasised that any final definition must be based on exhaustive scientific and geological assessment, ensuring holistic protection of the entire mountain system rather than fragmented pockets.

Environmental and Policy Implications

  • Over-reliance on technical definitions can undermine ecological objectives
  • Mining regulation must balance economic activity with inter-generational environmental equity
  • Judicial oversight remains critical in the absence of comprehensive legislative clarity
  • For policymakers, the issue underscores the need for scientifically grounded, ecosystem-based approaches rather than narrow physical thresholds.

Magnetic Levitation (Maglev) Technology

Maglev Technology

Magnetic Levitation Technology Latest News

Recently, Chinese scientists have achieved a milestone in magnetic levitation (Maglev) technology by successfully propelling a one-tonne vehicle to 700 kilometers per hour in just two seconds.

About Magnetic Levitation Technology

  • It is a transportation technology which uses electromagnets to lift, guide and propel trains without wheels, allowing the cars to levitate slightly above the tracks.
  • It is achieved through magnets in the guideway walls interacting with magnets on the train, move the train forward in an almost frictionless environment.

Working of Magnetic Levitation Technology

  • Maglev trains operate using two key electromagnetic principles: magnetic attraction and repulsion. 
  • The system typically consists of three main components:
    • Levitation: Magnets lift the train above the track, ensuring there is no physical contact. This minimizes wear and tear while providing a smooth ride.
    • Guidance: Electromagnets stabilize the train laterally, keeping it centered on the track.
    • Propulsion: Linear motors generate magnetic fields that push and pull the train along the track. This replaces the need for traditional engines or fuel.
  • The tracks, known as guideways, are embedded with powerful electromagnets, while the trains themselves contain superconducting magnets or electromagnets. 
  • By carefully controlling the magnetic fields, maglev trains achieve levitation and propulsion with minimal energy loss.

Benefits of Magnetic Levitation Technology

  • Reduced Friction: With no physical contact between train and track, maglev systems have significantly lower maintenance costs and higher energy efficiency.
  • Eco-Friendly: Maglev trains produce zero direct emissions and can be powered by renewable energy sources, making them a sustainable alternative to fossil fuel-based transport.

Spinal Muscular Atrophy

Spinal Muscular Atrophy

Spinal Muscular Atrophy Latest News

Recently, Abu Dhabi’s Sheikh Khalifa Medical City has become the first hospital globally to administer ITVISMA, a one-time gene therapy for spinal muscular atrophy (SMA).

About Spinal Muscular Atrophy

  • It is a rare and progressive neuromuscular disorder that leads to muscle weakness and can cause life-threatening complications. 
  • It is a debilitating genetic condition which affects motor neurons that control movement, and leads to progressive muscle weakening.
  • Cause: Most forms of SMA are caused by mutations of the survival motor neuron 1 gene (SMN1) on the fifth chromosome, resulting in insufficient expression levels of the SMN protein.
  • Types of SMA: There are five subtypes of SMA- type 0, 1, 2, 3, 4. Healthcare providers classify them based on the age of onset, as well as the severity and life expectancy.

Symptoms of Spinal Muscular Atrophy

  • Its symptoms vary and may be mild or disabling, but involve a weakness of the muscles that control movement.
  • The weakness in SMA tends to be more severe in the muscles that are close to the center of your body than in the muscles farther away from your body’s center.
  • Treatment: Unfortunately, there isn’t a cure for SMA. Treatment for SMA mainly seeks to manage symptoms and prevent complications.
