  • India’s 16-year wait ends: 26/11 conspirator Tahawwur Rana flown to Delhi, will face trial

    Why in the News?

    Over 16 years after the 26/11 Mumbai terror attacks, Tahawwur Rana, a key planner, was finally brought back to India from the US to face trial.

    Who is Tahawwur Rana? 

    Tahawwur Hussain Rana is a Pakistani-Canadian terrorist, businessman and former military doctor, who is known for his involvement in terrorism-related activities.

    What role did he play in the 26/11 Mumbai terror attacks?

    • Cover Identity: Tahawwur Rana provided a false business cover to David Headley, enabling him to enter India multiple times without raising suspicion. Eg: Rana’s immigration company, First World Immigration Services, was used to justify Headley’s visits to India as “business trips” while he was actually surveying 26/11 attack targets like the Taj Mahal Hotel and Chabad House.
    • Operational Support: Rana helped facilitate key documentation and communication links between Headley and terrorist organizations. Eg: He assisted Headley in obtaining a new passport with a false identity and supported contacts with Lashkar-e-Taiba (LeT) operatives, maintaining secrecy for the attack planning.
    • Logistical and Financial Assistance: Rana’s actions indirectly enabled the planning and execution of the attacks through financial backing and logistical coordination. Eg: He supported Headley’s multiple reconnaissance trips to Mumbai and funded arrangements that helped terrorists carry out the coordinated assault which killed 166 people and injured over 238.
    Note: David Headley is a Pakistani-American terrorist who conducted reconnaissance for the 26/11 Mumbai attacks on behalf of Lashkar-e-Taiba.

    What is the extradition treaty between India and the USA?

    • Bilateral Legal Framework: It is a formal agreement signed in 1997 that allows both countries to request and surrender individuals accused or convicted of serious crimes. Eg: India requested the extradition of Tahawwur Rana under this treaty for his role in the 26/11 Mumbai terror attacks.
    • Dual Criminality Principle: A person can be extradited only if the offense is a crime in both India and the United States. Eg: Conspiracy to commit terrorism is punishable in both countries, fulfilling the condition for Rana’s extradition.
    • Judicial and Diplomatic Process: The extradition process involves legal scrutiny by courts and coordination between diplomatic and law enforcement agencies of both nations. Eg: US courts reviewed Rana’s case and, after rejecting multiple appeals, extradited him with cooperation from the US Department of Justice.

    What legal processes did Tahawwur Rana undergo in the US before being extradited to India?

    • Extradition Hearing: A US District Court evaluated India’s request to determine if the charges met the treaty’s conditions and legal standards. Eg: In May 2023, the District Court for the Central District of California approved Rana’s extradition after reviewing evidence and charges.
    • Appeals and Legal Challenges: Rana filed multiple appeals to delay extradition, including petitions in higher courts and emergency applications. Eg: He moved the Ninth Circuit Court of Appeals and later the US Supreme Court with habeas corpus petitions, all of which were denied.
    • Final Clearance and Custody Transfer: After exhausting all legal options, US authorities coordinated with Indian officials to hand over Rana formally. Eg: The US Department of Justice and US Sky Marshal teams worked with Indian NIA and MEA for his secure transfer to Delhi.

    What is the role of the Unlawful Activities (Prevention) Act (UAPA)? 

    • Legal Designation of Terrorist Organizations: UAPA provides the legal framework to declare organizations as terrorist outfits and take action against their members and supporters. Eg: Lashkar-e-Taiba (LeT) and Harkat-ul-Jihadi Islami (HUJI), associated with Rana and Headley, are banned under UAPA.
    • Prosecution of Conspirators and Supporters: UAPA enables prosecution not only of terrorists but also of individuals who aid, abet, or conspire in terrorist acts. Eg: Tahawwur Rana is being charged under UAPA for facilitating logistics and shelter to Headley, who conducted reconnaissance for the 26/11 attacks.
    • Empowering NIA to Investigate: UAPA empowers the National Investigation Agency (NIA) to investigate and prosecute terrorism cases across India. Eg: The NIA formally arrested Rana under UAPA after his extradition, and is now interrogating him to expose the full conspiracy.

    Way forward: 

    • Strengthen International Counter-Terror Cooperation: Enhance collaboration on intelligence sharing, joint operations, and faster legal coordination under extradition treaties. Eg: Streamlined communication between NIA and FBI can prevent delays in apprehending fugitives and tracking transnational terror networks.
    • Fast-Track Trial and Victim Justice: Ensure expedited judicial proceedings to bring long-pending terrorism cases like 26/11 to closure and deliver justice to victims. Eg: A special fast-track court under the NIA Act can help conclude Rana’s trial swiftly, reinforcing public trust and legal deterrence.

    Mains PYQ:

    [UPSC 2021] Analyse the complexity and intensity of terrorism, its causes, linkages and obnoxious nexus. Also, suggest measures required to be taken to eradicate the menace of terrorism.

    Linkage: The issue of terrorism, its multifaceted nature, and the measures needed to combat it, which aligns with the context of the 26/11 attacks.

  • CPCB revises Classification of Industries

    Why in the News?

    The Central Pollution Control Board (CPCB) has recently updated its classification of industries, introducing a new category known as the ‘Blue Category.’

    Classification of Industries by CPCB:

    • The CPCB classifies industries based on their environmental impact, focusing on air pollution, water pollution, and hazardous waste generation.
    • Industries are classified using the Pollution Index (PI), which is calculated by considering air, water, and waste pollution, with equal weight given to each factor.
    • PI Categories:
      1. White: PI < 25 (least polluting industries)
      2. Green: 25 ≤ PI < 55
      3. Orange: 55 ≤ PI < 80
      4. Red: PI > 80 (most polluting industries)
    • This system helps determine industry locations, inspection norms, and pollution-related health impacts.
    • It is regulated by the Ministry of Environment, Forests, and Climate Change (MoEFCC) to improve environmental standards.
    • Presently 419 industrial sectors are categorized into Red, Orange, Green, White, and Blue.

    About the ‘Blue’ Category (Newly Introduced):

    • The Blue Category was introduced for industries providing Essential Environmental Services (EES) like pollution management and waste control.
    • It recognizes industries involved in critical environmental management, such as waste-to-energy plants, sewage treatment plants, and landfill management.
    • Industries in the Blue category receive a 2-year extension on their consent to operate as an incentive for their role in managing pollution.
    • Scope: Includes industries that manage waste from both domestic and industrial sources, such as:
      • Waste-to-Energy (WTE) Plants: Now in the Blue category despite their high PI, due to their role in waste energy recovery.
      • Compressed Biogas (CBG) Plants: Classified as Blue for their low environmental impact when processing municipal waste and agro residue.
      • Sewage Treatment Plants & Landfills: These facilities manage environmental hazards through controlled waste disposal.
    • Blue category industries must comply with all environmental norms, and their Pollution Index is still calculated as per the standard formula.
    • Industries showing successful management may receive extended operating permits and other incentives.

  • Extinct Dire Wolf species returns after 12,500 years

    Why in the News?

    Colossal Biosciences, a biotech firm based in US, has successfully bred the extinct Dire Wolf pups using gene-editing technologies.

    About Dire Wolf (Aenocyon dirus)

    • The dire wolf lived during the Pleistocene Epoch, approximately 6 million to 11,700 years ago, and went extinct around 13,000 years ago.
    • Physical Characteristics and Behaviour:
      • It was larger than the modern gray wolf, standing about 5 feet tall at the shoulder and weighing up to 150 pounds, significantly heavier than the average gray wolf.
      • It had a stockier body, a robust skull, and powerful jaws, adapted for hunting and consuming large prey. It likely had light or white fur, unlike the gray, black, or white coats of modern wolves.
      • As an apex predator, the dire wolf primarily preyed on large mammals like bison and horses.
      • While it did not hunt in packs as effectively due to its size, it was capable of cooperative hunting when needed.
    • Extinction:
      • The species went extinct likely due to a combination of prey depletion, climate change, and the impact of human activities.
      • Fossils have been found across a wide geographical range, from the La Brea Tar Pits in California to the Mississippi River Valley.
    • Genomic Comparison:
      • The gene-edited pups share 99.5% DNA of gray wolves but differ in the remaining 0.5%, which accounts for the dire wolf traits.
      • These pups are not exact clones of the dire wolf but are considered “dire wolves” based on their physical resemblance.

    Extinct Dire Wolf species returns after 12,500 years

    Technologies Used for Resurrection:

    • Ancient DNA Extraction & Analysis: DNA from 13,000 to 72,000-year-old fossils was sequenced to identify key genetic traits.
    • Gene Editing (CRISPR): Scientists used CRISPR to edit gray wolf DNA, introducing features like size, fur color, and muscular traits to resemble the dire wolf.
    • Somatic Cell Nuclear Transfer (SCNT): Edited somatic cells from gray wolves were used to create embryos implanted in dog surrogates. Genetically modified pups were born after 62 days.
    • Embryo Implantation: The gene-edited embryos developed into the first de-extinct dire wolf pups.
    [UPSC 2018] The term “”sixth mass extinction/sixth extinction”” is often mentioned in the news in the context of the discussion of:

    (a) Widespread monoculture practices in agriculture and large-scale commercial farming with indiscriminate use of chemicals in many parts of the world that may result in the loss of good native ecosystems.

    (b) Fears of a possible collision of a meteorite with the Earth in the near future in the manner it happened 65 million years ago that caused the mass extinction of many species including those of dinosaurs.

    (c) Large scale cultivation of genetically modified crops in many parts of the world and promoting their cultivation in other parts of the world which may cause the disappearance of good native crop plants and the loss of food biodiversity.

    (d) Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change.

     

  • Iron inside the Sun is more opaque than expected

    Why in the News?

    Recent findings have revealed that iron’s opacity inside the Sun may be much higher than previously predicted, challenging current solar models.

    Iron Inside the Sun:

    • Iron makes up approximately 0.14% of the Sun’s mass, which is significantly less than hydrogen (~74%) and helium (~24%).
    • Despite its small percentage, iron plays a crucial role in the Sun’s opacity. In the Sun, opacity influences how energy moves from the core to the surface.
    • The higher the opacity, the more energy is trapped, impacting the Sun’s temperature, density, and fusion rates.

    Highlights of the New Study:

    • A 2025 study published in Physical Review Letters revealed that iron’s opacity in the Sun’s interior is 30-400% higher than previously predicted by models.
    • Researchers exposed a thin iron sample to X-rays and used spectrometers to measure the shadow cast by the sample.
    • By analyzing how strongly the iron absorbed the radiation, they were able to infer the element’s opacity.
    • Significance:
      • This discovery has important implications for how solar models are constructed.
      • By correcting the opacity of iron, models of the Sun’s temperature profile, fusion rates, and energy distribution may need to be revised.
      • This will lead to a more accurate understanding of stellar behaviour and energy transfer.

    Back2Basics: Composition of the Sun

    • The Sun primarily comprises hydrogen and helium, but other elements such as oxygen, carbon, neon, and iron also play significant roles.

    Element

    Composition by Mass (%)

    Key Role
    Hydrogen (H) 74% The primary fuel for nuclear fusion in the Sun’s core. It undergoes fusion to form helium, releasing energy that powers the Sun.
    Helium (He) 24% A byproduct of hydrogen fusion, helium helps maintain the Sun’s stability and supports continued fusion processes.
    Oxygen (O) ~0.8% Oxygen contributes to the Sun’s opacity, assisting in the transport of energy within the star. It also plays a role in nucleosynthesis, where heavier elements are formed in the Sun’s core.
    Carbon (C) ~0.3% Carbon is involved in nucleosynthesis and plays a significant role in determining the Sun’s opacity and energy transport mechanisms.
    Neon (Ne) ~0.2% Neon is found in the Sun’s atmosphere and is involved in the absorption of radiation, affecting the Sun’s energy output and behavior.
    Iron (Fe) ~0.14% Although small in mass, iron significantly impacts the Sun’s opacity, scattering and absorbing radiation, which influences energy transfer. Iron’s opacity affects the Sun’s temperature, density, and fusion rates.
