1. Adamya: Recently, the Indian Coast Guard commissioned its newest fast patrol vessel, ICGS Adamya, at Paradip Port.
  • About Adamya: First in a series of eight Adamya-class fast patrol vessels.
  • Designed and built by Goa Shipyard Limited with over 60% indigenous content under Make in India.
  • 51-metre-long vessel; displacement ~320 tonnes.
  • Propelled by two 3,000 KW diesel engines, max speed 28 Knots, and endurance 1,500 nm.
  • Commanded by Commandant Anurag Pandey, with 5 officers and 34 personnel.
  • First ICG ship fitted with indigenously developed Controllable Pitch Propellers (CPP) and gearboxes.
  • Weaponry: 30 mm CRN-91 gun + two 12.7 mm stabilised remote-controlled machine guns with fire-control systems.

  • Ship will be based at Paradip (Odisha) under Coast Guard Region (North East).
  • Commissioned in the presence of Defence Ministry Joint Secretary Satyajit Mohanty and Inspector General Yoginder Dhaka.

2. Power of Chirality: Recently, researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, made a breakthrough in understanding how chiral perovskite films crystallize.
  • About Chirality: Non-superimposable mirror image property, common in nature (e.g., DNA, spiral galaxies).
  • Enables unique light–matter interactions, such as electron spin control and circularly polarized light (CPL) detection.
  • Researchers at CeNS Bengaluru discovered that crystallization in these films begins at the air–film interface and proceeds toward the substrate.
  • A key challenge is the formation of impurity phases caused by trapped solvent, which reduces film quality.
  • This can be overcome through vacuum processing and careful solvent selection, yielding phase-pure, uniform films.
  • Such films open pathways for advanced applications like CPL detectors, spintronic devices, and photonic synapses.
  • The breakthrough strengthens India’s potential leadership in semiconductors and quantum technologies.

3. World Trade Report 2025: Recently, the World Trade Organization (WTO) released its World Trade Report 2025, highlighting the transformative role of Artificial Intelligence (AI) in shaping global trade and growth.
  • About World Trade Report 2025: Annual Flagship Publication of WTO, examining global trade trends, policies, and the future of the multilateral trading system.
  • 2025 Theme: “Making Trade and AI Work Together to the Benefit of All” — focusing on AI’s impact on trade and inclusive development.
  • Key Highlights: The report estimates that by 2040, AI could increase global trade by 34–37% and GDP by 12–13%, provided digital divides are bridged and inclusive policies are pursued.
  • AI as a Trade Multiplier: AI could raise global trade in goods and services by nearly 40% by 2040, through reduced trade costs and productivity gains.
  • Global GDP Impact: AI adoption, if spread across countries, could lift global GDP by 12–13%.
  • AI-Trade Synergy: AI enhances efficiency in supply chains, logistics, and customs clearance, benefiting SMEs.


      4. Plasticdweep: Recently, Lakshadweep faced a Plasticdweep waste crisis after a fire at Minicoy Island’s dump yard exposed its 4,000-tonne waste problem, threatening reefs, ecosystems, and fisherfolk livelihoods.
      • About Plasticdweep: Refers to the worsening marine and land waste crisis in Lakshadweep.
      • The Minicoy fire revealed years of neglected waste management, unregulated dumping, and the absence of a functional disposal system.
      • Data & Trends: CUSAT Survey 2024: Found 32,710 litter items on 28 beaches, with 59% of coral colonies smothered and 15% coral bleaching recorded.
        - Governance Failure: After the 2021 dismantling of panchayats, regular waste collection stopped, leading to unchecked dumping and open burning.- Logistical Barriers: Waste evacuation possible only 4–5 months annually due to monsoons; barges mainly used for essential supplies (food and fuel).
      • Implications: Ecological: Coral degradation → collapse of fish stocks → loss of marine biodiversity.
        - Livelihood: Severe threat to fishing-dependent communities, food security, and tourism prospects.
        - Health: Exposure to toxic smoke, groundwater contamination from leachate, and microplastic bio-accumulation in the food chain.

                        6. Air Defence Radars: Recently, the Indian Army initiated the procurement of advanced Air Defence radars after Operation Sindoor revealed critical gaps in detecting and countering drones and low-flying aerial threats.
                        • About Radars: Systems use radio waves to determine the direction, distance, and velocity of airborne objects.
                        • Types of Radars: Surveillance Radars: Scan and identify aerial objects.

                                            ·      About El Niño: The warm phase of the El Niño–Southern Oscillation (ENSO), marked by unusual warming of sea surface temperatures in the central and eastern tropical Pacific Ocean.

                                            • Effect: Disrupts normal atmospheric circulation, impacting global weather and climate patterns.
                                            • Formation: Under normal conditions, trade winds push warm water westward (towards Indonesia), with cold water upwelling off South America.
                                            • During El Niño: Trade winds weaken, warm water shifts eastwards.
                                            • Thermocline deepens, reducing nutrient-rich upwelling.
                                            • Alters Pacific jet streams and global circulation, causing weather anomalies worldwide.
                                            • Factors Contributing to El Niño: Weakening of easterly trade winds (natural variability).
                                            • Positive SST anomaly of ≥0.5 °C above average, lasting at least 5 overlapping 3-month seasons.
                                            • Westerly wind bursts, the Madden–Julian Oscillation (MJO), and influence of global warming.
