1. Iridogorgia Chewbacca: Recently, scientists discovered a unique deep-sea coral and named it
Iridogorgia Chewbacca, inspired by the Star Wars character Chewbacca because of its hairy appearance.
- About Iridogorgia Chewbacca: A newly discovered deep-sea coral species from the genus Iridogorgia
- Found in the tropical western Pacific Ocean
- First sighted near Molokaʻi in 2006 and later close to the Mariana Trench in 2016
- Features: Part of the Iridogorgia group, which has long, spiral-shaped structures
- Distinguished by its flexible, shiny branches
- Each colony is built by thousands of polyps working together
- Typically seen alone, scattered on rocky seabeds in deep waters
2. Prehistoric Insects: Recently, scientists discovered
prehistoric insects preserved in amber in South America, offering a rare glimpse into Earth’s ancient ecosystems.
- Key Findings: Amber specimens date back about 112 million years (Cretaceous period).
- Significance: Offers a glimpse into life when flowering plants were starting to diversify.
- Insects Found: Ancient beetles, flies, ants, and wasps identified in the amber.
- Global Context: Most amber deposits from the last 130 million years were found in the Northern Hemisphere; few were known from Gondwana (southern regions).
- Site: Genoveva quarry in Ecuador, on the edge of the Amazon basin.
- Types of Amber: Root-formed amber (did not preserve specimens).
- Air-exposed amber (contained insects, pollen, and leaves).
- Ecosystem Evidence: Indicates the area was once a humid, resinous forest with ferns, conifers, and Monkey Puzzle Trees — very different from today’s Amazon rainforest.
- Scientific Importance: Helps study the early interactions between flowering plants and insects during the dinosaur era.
3. Sawalkote Dam: Recently, the long-delayed
Sawalkote dam in Jammu & Kashmir came back into focus as the Environment Ministry’s panel gets ready to review NHPC’s 1,865 MW project.

- Top 5 fastest-growing districts (economic growth): Patna, Vaishali, Muzaffarpur, Gaya, Begusarai.
- Top 5 emerging districts (economic growth): Arwal, Jehanabad, Jamui, Banka, Madhubani (many previously Maoist-affected).
- Overall growth: Bihar recorded a 351% rise in NTL between 2017 and 2023.
- Sectors linked with high luminosity: Construction, retail, agriculture, animal husbandry (mostly unorganised/SME sector).
- Employment insights: Patna: 51% employment from startups in IT/ITES, e-commerce, healthcare
- Secondary hubs: Muzaffarpur, Darbhanga, Bhagalpur
- Smaller hubs: Gaya, Arwal, Banka
5. Maiden Bilateral Maritime Exercise: Recently, the
first-ever bilateral maritime exercise between the Indian Navy and the Hellenic Navy concluded in the Mediterranean Sea, marking a key milestone in strengthening defence ties between India and Greece.
- About Maiden Bilateral Maritime Exercise: Conducted 13–18 Sept 2025 in the Mediterranean Sea.
- Phases: Harbour phase (13–17 Sept): Held at Salamis Naval Base; included cross-deck visits, professional exchanges, pre-sail conference on HS Themistokles (Elli-class frigate), and cultural events showcasing Indian traditions.
- Sea phase (17–18 Sept): Featured complex naval drills — night VBSS (Visit, Board, Search, and Seizure) operations, replenishment-at-sea, joint Anti-Submarine Warfare, coordinated gun firing, and cross-deck helicopter operations.
- Indian Representation: INS Trikand (guided missile stealth frigate).
- Cultural Diplomacy: Hosted Indian Ambassador to Greece, Commodore Spyridon Mantis, senior Hellenic Navy officers, and families; crew also visited the Sacred Rock of Acropolis.
- Significance: Strengthened India-Greece defence cooperation.
- Enhanced operational interoperability and professional synergy.
- Reflected shared commitment to maritime security, stability, and freedom of navigation in global commons.
- Next Phase: INS Trikand continued her deployment in the Mediterranean after the exercise.
6. Extreme Nuclear Transients: Recently, scientists identified
Extreme Nuclear Transients (ENTs) as the most powerful transient events, releasing up to ten times more energy than gamma-ray bursts.
- About ENTs: Occur when supermassive black holes tear apart very massive stars (≥ 3 times the Sun’s mass).
- Cause: Triggered by the violent accretion of stellar debris after the star is destroyed.
- Process: As the star nears the event horizon, tidal forces stretch it into a spaghetti-like stream (spaghettification). This generates an immense burst of electromagnetic energy, which stays luminous for years, especially in radio wavelengths.
- Difference from Other Events:
- TDEs (Tidal Disruption Events): ENTs are rarer, occur in larger galaxies with more massive black holes.
- FXTs (Fast X-ray Transients): Short-lived, low-energy X-ray bursts caused by particle jets trapped in supernovae; unlike long-lasting, powerful ENTs.
- Significance: Provide insights into massive black holes in the early universe.
- Enable study of black holes not actively accreting.
7. Smog-Eating Coatings: Recently, the government announced a technology-backed study on “
smog-eating”
photocatalytic coatings, a titanium oxide-based treatment that breaks down harmful air pollutants.
- About Smog-Eating Technology: Titanium oxide-based coatings applied on roads and public surfaces reduce nitrogen dioxide (NO₂) and hydrocarbons in the air.
- Global use: Tested in some international cities, but not yet introduced in India.
- Study focus: Safety of the coating in real-world conditions.
- Sustainability across different urban environments.
- Cost-effectiveness for large-scale application.
- Mapping credible suppliers for potential rollout.
- Objective: Assess the effectiveness, safety, sustainability, and affordability before considering a city-wide deployment in Delhi.
8. Aflatoxin: Recently, Indonesia suspended groundnut imports from India over
aflatoxin contamination concerns, as exporters raised objections to delayed notification and non-WTO-compliant testing procedures.
- About Aflatoxins: Toxic secondary metabolites produced by fungi Aspergillus flavus and Aspergillus parasiticus.
- Belong to the class of mycotoxins (toxic fungal chemicals).
- Thrive in hot, humid climates, contaminating groundnuts, maize, rice, spices, tree nuts, and crude oils both pre- and post-harvest.
- Key Features: Heat stable, not destroyed by cooking or processing.
- Genotoxic & carcinogenic, can damage DNA and cause cancer.
- Invisible contamination, cannot be detected by sight, smell, or taste; needs lab testing.
- Global concern, regulated by Codex Alimentarius and WTO SPS standards.
- Impacts on Food & Health: Liver cancer, immune suppression, growth retardation in children, and acute aflatoxicosis in severe cases.
- Causes trade rejections, farmer income loss, and wastage of consignments.
9. Amogh Fury Exercise: Recently, the Indian Army carried out a large-scale integrated firepower exercise named
'AMOGH FURY' at the Mahajan Field Firing Ranges in Rajasthan’s Thar desert.
- About Exercise Amogh Fury: Integrated Fire Power Exercise by the Sapta Shakti Command of the Indian Army.
