• Symbolism: Armenia is a designated global biodiversity hotspot. The official logo features the Yerevan Blue Butterfly, while its 23 distinct colours represent the 23 targets of the global framework.
• Attendance: Attended by representatives from 196 parties (195 states plus the European Union). Notably, the United States remains one of the only countries that has not ratified the treaty.

• The Convention on Biological Diversity (CBD) is a legally binding multilateral environmental treaty opened for signature at the Rio Earth Summit, 1992, and entered into force in 1993.
• It has 196 Parties, including countries and the European Union; the United States is a signatory but not a Party.
• Its three objectives are:
  • Conservation of biological diversity;
  • Sustainable use of its components;
  • Fair and equitable sharing of benefits arising from genetic resources.
• The CBD secretariat is located in Montreal, Canada.
• India is a Party to the CBD; domestic implementation is supported through the Biological Diversity Act, 2002 and the National Biodiversity Authority.

• The Kunming–Montreal Global Biodiversity Framework (KMGBF) was adopted at COP15 in Montreal in December 2022.
• It is the global roadmap to halt and reverse biodiversity loss by 2030 and put nature on a path to recovery by 2050.
• It contains 23 action-oriented targets for 2030 and four long-term goals for 2050.
• It also seeks to restore 30% of degraded ecosystems by 2030.
• Other targets address harmful subsidies, pollution, invasive alien species, climate-biodiversity linkages, sustainable agriculture, and benefit-sharing from genetic resources.

• The "30 by 30" Target: Ensuring countries remain legally bound and motivated to protect at least 30% of the Earth's land and sea ecosystems by 2030.
• Subsidy and Financial Reform: Reviewing plans to reform $500 billion per year in environmentally damaging subsidies and driving the transfer of $30 billion annually from developed nations to developing countries for conservation.
• The Cali Fund Test: Ironing out the mechanisms of the "Cali Fund"—a protocol to ensure that corporations profiting from the digital genetic data of nature pay a fair share into conservation projects.
• Empowering Indigenous Voices: Establishing a permanent decision-making body within the UN framework for Indigenous Peoples and Local Communities (IPLCs), who steward over 80% of the planet's remaining biodiversity.

• The summit is hosting two overlapping international meetings: the 12th meeting of the Parties to the Cartagena Protocol on Biosafety (CP-MOP-12) and the 6th meeting of the Parties to the Nagoya Protocol on access and benefit-sharing of genetic resources.

• Enormous Length: Scientists estimate the snake measured between 11 to 15 metres (36 to 50 feet) in length, making it longer than a T-Rex or a standard school bus.
• Immensely Heavy Build: It had a broad, cylindrical body approximately 17 inches wide, weighing an estimated 1 metric tonne.
• Fossil Evidence: The discovery is based on 27 exceptionally well-preserved pre-cloacal vertebrae, with individual vertebrae measuring up to 4.4 inches wide.

• Mythological Roots: The genus name Vasuki is named after the mythical serpent king from Hindu tradition, who is depicted coiled around the neck of Lord Shiva.
• Geographical Identity: The specific name indicus directly signifies India, the country of its discovery.

• The Eocene Epoch: It lived approximately 47 million years ago during the Middle Eocene period.
• Swampy Environment: During this period, the Kutch region of Gujarat was not a desert, but a hot, humid, tropical swamp landscape.
• Co-existing Species: It shared its ecosystem with primitive whales, turtles, crocodiles, and giant catfish.

• Madtsoiidae Family: It belonged to the Madtsoiidae family, an extinct lineage of terrestrial snakes that thrived for nearly 100 million years across Gondwanan landmasses (Africa, South America, India).
• Non-Venomous Constrictor: Much like modern pythons and anacondas, Vasuki indicus was non-venomous.
• Ambush Predator: Due to its colossal size, it was a slow-moving predator that ambushed its prey (likely hunting crocodilians and small mammals) and suffocated them using constriction.

• Ancient Climate Indicator: As a cold-blooded reptile, its massive size implies that the Middle Eocene tropics had high average annual temperatures (around 28°C / 82°F) to support its massive metabolic needs.
• Evolutionary Insights: The find provides critical information regarding the geographic distribution of ancient reptiles and how they migrated across continents when India collided with Eurasia roughly 50 million years ago.
• Extinction Cause: The lineage is believed to have eventually died out due to major global cooling events that occurred millions of years later.

• Oldest Quasi-Judicial Body: Established on January 25, 1941, under Section 5A of the Income Tax Act, 1922, it is famously referred to as the "Mother Tribunal" of India.
• Administrative Subordination: It functions independently under the Ministry of Law and Justice (Department of Legal Affairs), rather than the Ministry of Finance, ensuring complete impartiality from the Income Tax Department.
• Motto: It operates under the guiding principle of "Nishpaksh Sulabh Satvar Nyay" (Impartial, Easy, and Speedy Justice).

• Second Appellate Authority: It acts as the second forum to hear income tax appeals after the initial order passed by the Commissioner of Income-tax (Appeals).
• Final Fact-Finding Body: The ITAT is the supreme authority on matters of fact. Its decisions regarding factual evidence are final and irrevocable.
• Higher Judicial Appeals: An order passed by the ITAT can only be challenged in the regional High Court or the Supreme Court if a substantial question of law arises.

• Geographical Benches: Headquartered in Mumbai, the ITAT currently operates 63 benches across 27 cities in India.
• Benches Composition: A standard division bench consists of one Judicial Member (appointed from the judiciary or practicing bar) and one Accountant Member (appointed from Chartered Accountants or senior tax officials).
• Single Member Benches (SMC): A single member can independently resolve cases where the total assessed income does not exceed ₹50 lakh.
• Special Benches: For high-value or deeply complex legal questions, the President of the ITAT can constitute a Special Bench comprising three or more members.

• Self-Regulating Procedures: Under Section 255 of the Income Tax Act, 1961, the ITAT is empowered to regulate its own judicial processes and proceedings.
• Power to Grant Stay: It possesses the authority to grant a stay on tax recovery demands even before a formal tax demand is processed, facilitating immediate relief to taxpayers.
• Filing Window: Any aggrieved taxpayer or the Income Tax Department's Assessing Officer must file an appeal before the ITAT within 60 days of receiving the lower authority's order.

• Dual Degradation Strategy: The technology integrates two phenomena—Photocatalysis (using light energy) and Piezocatalysis (using mechanical vibrations)—to chemically break down pollutants.
• The Power of Vibration: Traditional light-based filters lose efficiency because light-generated electrons and holes recombine too quickly. Introducing mechanical vibrations (such as ultrasonic waves) creates a piezoelectric effect that prevents this recombination, accelerating dye destruction.
• Smart Engineering: Unlike conventional treatments that use loose nanoparticle powders (which are difficult and hazardous to recover from treated water), these nanoparticles are safely immobilised inside a porous membrane.

• Biodegradable Base: The structural network of the filter is made using polylactic acid (PLA) nanofibres, a sustainable and biodegradable plastic.
• Green Nanoparticles: The active catalyst consists of Zinc Oxide (ZnO) nanoparticles.
• Turmeric-Based Synthesis: To completely avoid toxic chemical reagents, the researchers used turmeric extract. Natural compounds in turmeric (curcumin, flavonoids, and phenolics) acted as natural reducing and stabilising agents.
• Machine Learning Integration: Artificial intelligence models were built directly into the system to analyze variables like light intensity, dye concentration, and ultrasonic frequency to accurately predict dye-decolourisation performance.

• Rapid Dye Destruction: Under combined light and ultrasonic excitation, the filter achieved 98.6% decolourisation of Methylene Blue (MB) dye and 96.7% of Congo Red (CR) dye within just 120 minutes.
• Destruction Over Separation: Traditional methods like adsorption or sedimentation merely separate dyes from water, creating a secondary toxic sludge. This nanofibre filter chemically alters and destroys the toxic dye molecules.
• Antibacterial Action: The membrane doubles as a bio-filter, inactivating approximately 75% of E. coli and 71% of S. aureus bacteria within six hours.

• Textile & Printing Effluents: Treating the heavily coloured, toxic wastewater discharged by fabric and dye manufacturing units before it reaches natural water bodies.
• Environmental Remediation: Restoring water quality in industrial hubs where groundwater or river channels are suffering from persistent chemical pollution.
• Advanced Water Systems: Designing commercial, self-cleaning, and antimicrobial water purification membranes for broader public safety use.

• On October 17–18, 2026, more than 5 lakh people protested across France; the Interior Ministry estimated 550,000 participants, while the CGT union claimed 800,000.
• France is witnessing its largest nationwide unrest in years: protests began over poor school conditions and have expanded into a mass movement against the cost of living, inequality, and weakening public services.

• Massive Turnout: Over 550,000 citizens participated in demonstrations across the country over a single weekend.
• Severe Infrastructure Damage: While most marched peacefully, fringe groups and "black block" rioters caused severe damage. In Limoges, a 140-year-old town hall was torched, causing its iconic architectural spire to completely collapse.
• Looting of Luxury Retail: High-end shopping districts in Paris, such as Place Vendôme, were heavily targeted. Front doors and windows of major luxury brands like Dior, Rolex, Louis Vuitton, and Gucci were smashed and ransacked.
• Louvre Shutdown: Student demonstrators blocked the entrance to the famous Louvre Museum in Paris to condemn police actions, forcing the institution to temporarily shut down.
• High Casualties and Arrests: The clashes have resulted in at least one protester's death, over 2,000 arrests, and injuries to more than 600 police officers and firefighters.

• Nightly Curfews Imposed: Authorities have instituted overnight curfews in central Paris (including Place de la République and Les Halles) as well as sections of Lyon, Bordeaux, Nice, and Marseille. Some areas have placed specific night curfews on minors.
• Military Assistance Deployment: Soldiers from France's "Sentinelle" anti-terrorism operation are being deployed to guard static, sensitive public sites. This frees up thousands of specialized riot police officers for active crowd control.
• Political Gridlock: President Macron’s government currently lacks a single-party majority in parliament. This structural weakness is complicating efforts to legally address the protesters' socioeconomic demands or implement harsher security measures.

• Renewed Demonstrations: Student unions and grassroots groups have already called for a fresh wave of massive nationwide protests on Saturday, October 24.
• Imminent Trade Union Strikes: France’s major inter-union organizations, including the CGT, have announced a countrywide general strike scheduled for November 5 to pressure the government over worker conditions.
• Regional Ripple Effect: The underlying financial frustration is not unique to France; high housing costs and inflation have concurrently sparked similar cost-of-living protests across Italy, Portugal, Belgium, and Albania.
