The Supreme Court invalidated key provisions of the Tribunal Reforms Act 2021 on grounds that they violated judicial independence and the constitutional separation of powers.

• Provisions invalidated:
  • Four-year tenure for tribunal members. The Court held that shorter tenures reduce the effective independence of quasi-judicial bodies from executive pressure.
  • Minimum age of 50 for appointments. The Court found this restriction arbitrarily narrows the pool of qualified candidates without constitutional justification.
  • Executive appointment control provisions that gave the government disproportionate influence over selection processes.
• Constitutional principle: the Court applied the doctrine of separation of powers and reaffirmed that tribunal members exercise judicial functions. Their independence must be structurally guaranteed and cannot depend on executive goodwill.
• Remedial direction: the Court directed the government to establish a National Tribunal Commission within four months. The Commission would independently manage tribunal appointments, tenure, and administration.
• Consequential abolitions under the 2021 Act: the Tribunal Reforms Act 2021 had already abolished the Film Certification Appellate Board (now called Film Certification Appellate Tribunal) and the Intellectual Property Appellate Board. The Act's tenure and appointment provisions were the contested portions.
• Background: the Supreme Court has repeatedly struck down executive dilution of tribunal independence. Rojer Mathew v. South Indian Bank (2019) and Madras Bar Association v. Union of India (2021) are the immediate precedents.

The legal and policy framework for transgender rights in India rests on a foundational Supreme Court judgment and a 2019 Act.

• Population data: the Census 2011 recorded 4.87 lakh individuals who self-identified as transgender. This is considered an undercount.
• NALSA Judgment (2014): National Legal Services Authority v. Union of India. The Supreme Court recognised transgender persons as the "third gender," affirmed their right to self-identification without surgery or medical certification, and held that they are entitled to all fundamental rights.
• Constitutional backing: Articles 14 (equality before law), 15 (non-discrimination), 16 (equal opportunity in public employment), 19 (freedoms), and 21 (right to life and dignity) collectively protect transgender persons.
• Transgender Persons (Protection of Rights) Act 2019: provides a legal definition of transgender persons, establishes anti-discrimination protections in education, employment, healthcare, and public services, and mandates a certificate of identity process.
• National Portal for Transgender Persons: enables online self-identification and issue of the identity certificate mandated under the 2019 Act.
• SMILE Scheme 2022: Support for Marginalised Individuals for Livelihood and Enterprise. Provides livelihood support, scholarships, and inclusion in Ayushman Bharat health coverage through a dedicated component called TG Plus.

IUCN data shows declining dugong populations in Indian waters across the Gulf of Kutch, Gulf of Mannar, and Andaman and Nicobar Islands.

• IUCN Red List status: Vulnerable globally. Indian populations are considered to be in decline.
• Domestic legal protection: Schedule I of the Wildlife (Protection) Act 1972.
• Physical characteristics: adults weigh 300 to 420 kg and reach up to 3 metres in length.
• Diet and ecological role: consume 30 to 40 kg of seagrass daily. This grazing maintains seagrass meadow health, making dugongs ecosystem engineers. Seagrass beds in turn serve as nursery habitat for fish and sequester carbon.
• Lifespan: up to 70 years, which is long for a marine mammal.
• Reproduction rate: females give birth only once every 3 to 7 years. This slow reproduction makes population recovery from declines extremely difficult.
• Major threats:
  • Habitat loss from seagrass degradation caused by coastal construction and water pollution.
  • Fisheries bycatch (accidental entanglement in fishing gear).
  • Marine pollution involving heavy metals including arsenic, cadmium, mercury, and lead. These bioaccumulate in dugong tissue.
• India's dugong conservation programme: India designated the Gulf of Mannar as a Dugong Conservation Reserve in 2021.

The traditional brass military bugle handcrafted in Meerut received a Geographical Indication tag from the GI Registry in Chennai.

• Product: a brass wind instrument used in Indian military parades, ceremonial occasions, and regimental functions.
• Historical origin: the Meerut bugle tradition dates to the late 19th century under the British colonial administration. Meerut was a major cantonment town and military manufacturing centre.
• Craft process: handcrafted using high-quality brass. Artisans in Meerut have maintained the craft across generations within the same families and localities.
• GI Registry: the Geographical Indications Registry operates under the Department for Promotion of Industry and Internal Trade (DPIIT). Its office is in Chennai.
• India's GI tally: India now holds 605 GI-tagged products across handicrafts, food, agricultural products, and manufactured goods.
• Prelims distinction: a GI tag is granted under the Geographical Indications of Goods (Registration and Protection) Act 1999. It protects the name of a product from being used by others outside the designated geographic origin.

BIRSA 101 is India's first indigenous CRISPR-based gene therapy for Sickle Cell Disease. It was developed jointly by CSIR-IGIB and the Serum Institute of India.

• Developing institutions: CSIR-Institute of Genomics and Integrative Biology (IGIB) and Serum Institute of India.
• Disease target: Sickle Cell Disease (SCD), an inherited blood disorder in which red blood cells become rigid and sickle-shaped, blocking blood flow and causing severe pain, organ damage, and anaemia.
• Technology platform: enFnCas9, a fully indigenous CRISPR gene editing system developed by CSIR-IGIB. This is distinct from the SpCas9 system used in most global CRISPR therapies. India's indigenous platform matters for patent independence.
• Mechanism: the therapy edits the patient's own stem cells to correct or compensate for the defective haemoglobin gene. The corrected cells are reinfused into the patient.
• Name significance: named after Birsa Munda to mark his 150th birth anniversary. Sickle Cell Disease disproportionately affects tribal communities in India, including communities in Jharkhand and central India who are historically associated with Birsa Munda.
• Cost comparison: global CRISPR-based SCD treatments (such as Casgevy) cost Rs 20 to 25 crore per patient. BIRSA 101 is intended as an affordable alternative for India's patient population.
• Policy alignment: supports India's "Sickle Cell-Free by 2047" mission, which aims to eliminate SCD through screening, counselling, and treatment by the centenary of Indian independence.

Scientists at the Kodaikanal Solar Observatory reconstructed 118 years of the Sun's polar magnetic history from archival images. The data will help forecast Solar Cycle 25 and predict solar storms.

• Establishment: 1899. Over 125 years of continuous operation.
• Systematic imaging programme: solar imaging in the Ca II K (calcium ionised) wavelength began in 1904. This is the oldest continuous solar photographic record in Asia.
• Research finding (2025): scientists reconstructed the Sun's polar magnetic field history from 1904 to 2022. This 118-year dataset provides a baseline for understanding the solar dynamo and predicting future cycles.
• Application: the data improves forecasts for Solar Cycle 25 (the current cycle, which began in December 2019 and is expected to peak around 2025). Better cycle predictions help anticipate solar storms that disrupt satellites, power grids, and communications.
• Location: Palani Hills, Tamil Nadu.
• Administering body: field station of the Indian Institute of Astrophysics (IIA), Bengaluru.
• Prelims hook: the Indian Institute of Astrophysics is an autonomous institution under the Department of Science and Technology. Its other major observatory is the Vainu Bappu Observatory at Kavalur, Tamil Nadu.

The United States designated Saudi Arabia as a Major Non-NATO Ally (MNNA), extending the list to 20 countries.

• MNNA total: 20 nations now hold the designation. Earlier MNNA countries include Japan, Australia, Israel, South Korea, New Zealand, Brazil, and Pakistan.
• Benefits of MNNA status:
  • Priority access to surplus US defence equipment under the Excess Defence Articles programme.
  • Eligibility for US War Reserve Stockpiles pre-positioned abroad.
  • Joint research and development agreements on defence technology.
  • Enhanced military training access.
• India's distinct category: India is not an MNNA. Instead, India holds Major Defence Partner (MDP) status, a unique designation created by the US Congress specifically for India in the National Defence Authorisation Act 2017. MDP provides similar cooperation benefits without the alliance terminology.
• Strategic context: Saudi Arabia's designation signals US intent to formalise and deepen defence cooperation in the Gulf amid Iran's nuclear programme and regional instability. It also has implications for India's West Asian engagement.

A wild tiger permanently settled at Ratanmahal Wildlife Sanctuary in Gujarat, staying continuously for nine months. This is the first permanent tiger settlement in the sanctuary in decades.

• Location: Dahod district, central Gujarat. The sanctuary sits along the Gujarat-Madhya Pradesh border.
• Area: 65 square kilometres of reserve forest.
• Sanctuary declaration: declared a wildlife sanctuary in March 1982.
• Tiger significance: the tiger appears to have dispersed from Madhya Pradesh, where tiger populations have grown beyond the carrying capacity of some reserves.
• Three big cats coexisting: Ratanmahal reportedly supports Asiatic lion, Indian leopard, and tiger. This makes it potentially unique in India, as it is the only reserve that could host all three of India's major big cat species simultaneously. Asiatic lions are found only in and around Gir, Gujarat.
• Conservation implication: natural tiger dispersal into Gujarat expands the species' range and supports genetic connectivity between central Indian tiger populations.

Seventeen countries including France, Brazil, Belgium, Canada, and Singapore joined the Blue NDC Challenge at COP30 to integrate ocean climate action into national climate plans.

• Platform: Blue NDC Challenge, launched at COP30 in Belem, Brazil.
• Joining countries: 17 nations including France, Brazil, Belgium, Canada, and Singapore.
• Oceans and emissions: the ocean economy has the technical potential to deliver up to 35% of the global emission reductions needed to keep warming within 1.5 degrees Celsius.
• Current finance gap: ocean climate finance represents less than 1% of total global climate finance despite the ocean's large mitigation and adaptation potential.
• Five focus sectors:
  • Marine conservation and ecosystem restoration.
  • Ocean food systems (sustainable fisheries and aquaculture).
  • Offshore renewable energy.
  • Shipping decarbonisation.
  • Coastal and marine tourism (managed sustainably).
• NDC integration significance: Nationally Determined Contributions under the Paris Agreement currently have weak ocean chapters. The Blue NDC Challenge asks countries to explicitly include ocean-based targets and finance in their revised NDCs.
• India context: India has a significant coastline of 7,516 km and a large Exclusive Economic Zone. Ocean-based mitigation sectors (offshore wind, seagrass restoration) are directly relevant to India's revised NDC targets.
