3. Hayli Gubbi Volcano: Recently, India began preparing for possible air travel disruptions as volcanic ash from Ethiopia’s Hayli Gubbi volcano drifted toward the Indian mainland. The volcano has erupted for the first time in 10,000 years.

• Key Highlights: The eruption sent a massive ash cloud up to 14 km high, drifting across the Red Sea, Yemen, Oman, Pakistan, and reaching India.

• Affected Indian regions include: Delhi, parts of Uttar Pradesh, Bihar, Sikkim, Arunachal Pradesh, and central India.

• Volcanic ash contains abrasive, glass-like particles that:

• Can damage aircraft engines

• Melt at high temperatures

• Solidify into glass-like deposits on turbine blades

• Affect engine performance and safety

• About Hayli Gubbi: Situated about 800 km (500 miles) northeast of Ethiopia’s capital, Addis Ababa.

• It is the southernmost volcano in the Erta Ale Range, a major volcanic chain in the Afar region of Ethiopia. This is famous for its persistent lava lakes and is largely composed of shield volcanoes.

4. Asian and Pacific Centre for Development of Disaster Information Management: Recently, the 10th Session of the Asian and Pacific Centre for Development of Disaster Information Management (APDIM) on inclusive disaster risk data governance was held in New Delhi.

• About APDIM: A regional institution under the UN Economic and Social Commission for Asia and the Pacific (ESCAP).

• Regional Cooperation: Promotes cross-country coordination, dialogue, and collaboration for improved disaster risk information management.

5. Auramine O: Recently, India has been dealing with repeated food adulteration cases where non-permitted synthetic dyes are used, especially the commonly found auramine O.

• About Auramine O: A bright yellow industrial dye, widely used in textiles, leather, paper, printing inks, and lab staining—not approved as a food colour in India, the EU, the U.S., or most countries.

• Inspections and studies have revealed auramine in sweets, savoury snacks, and brightly coloured street foods, especially items resembling saffron or turmeric.
• Food adulteration has a long history in India, involving dyes and chemicals like metanil yellow, rhodamine B, Sudan dyes, argemone oil, calcium carbide, urea, mineral oils, and chalk powder, indicating structural regulatory weaknesses.
• o   Health Risks: Liver & kidney damage, Spleen enlargement, Mutagenic effects and Potential carcinogenic outcomes.
• o   The IARC (WHO) classifies industrial production of auramine as Group 1 – carcinogenic to humans, while ingestion is classified as possibly carcinogenic.
• o   Even low-dose, long-term exposure can cause physiological and genetic damage.
• o   Children are at greater risk due to higher consumption of bright-coloured foods.

6. Ningaloo Reef: Recently, a new survey showed that nearly 70% of corals at the UNESCO-listed Ningaloo Reef in Western Australia have died.

• Key Findings: Australia experienced its longest, largest, and most intense marine heatwave ever recorded, leading to severe mass bleaching.

• Coral mortality now exceeds 60% across eight northern lagoon sites between Osprey Sanctuary Zone and Tantabiddi Sanctuary Zone.
• Researchers assessed 1,600+ corals, only ~600 survived — most bleached corals did not recover.
• Earlier estimates indicated 30–90% bleaching along the 1,500-km coastline of Ningaloo.
• Bleaching extended even to supposedly resilient areas like Rowley Shoals and northern Kimberley reefs.
• The underwater heatwave superheated the entire water column down to 300 meters — unprecedented in Australia.
• A few resilient species survived (e.g., Veron’s tube coral, lesser knob coral).
• But dominant species such as staghorn corals (Acropora) and thin birdsnest coral have largely died out.
• Between Jan 2023 and Sep 2025, 4% of the world’s coral reef area experienced bleaching-level heat stress, with documented mass bleaching in 83 countries/territories.

7. Uranium: Recently, a new study found alarming levels of uranium in the breast milk of women across six districts in Bihar.

• Key Findings: Uranium levels reached up to 25 µg/L, with every sample showing contamination; there is no global permissible limit for uranium in breast milk.

• Earlier studies in the region had already detected arsenic and lead in breast milk, indicating a worsening pattern of toxic exposure.
• The findings pose significant health risks for infants, who are more vulnerable to non-carcinogenic effects than mothers.
• No carcinogenic risk was observed, but infants face a high potential for non-cancer health complications due to uranium exposure.
• Uranium levels were measured using the Agilent 7850 LC-ICP-MS.
• Study published in Nature journal titled: “Discovery of uranium content in breast milk and assessment of associated health risks for mothers and infants in Bihar, India.”
• 70% of infants exposed showed potential for non-carcinogenic health impacts.
• Likely sources of contamination: Drinking water and locally grown food. Both linked to areas with known groundwater uranium contamination.
• India has uranium-contaminated groundwater in 151 districts across 18 states.
• In Bihar, 11 districts face groundwater uranium contamination: Gopalganj, Saran, Siwan, East Champaran, Patna, Vaishali, Nawada, Nalanda, Supaul, Katihar, and Bhagalpur.

8. Biomass Pellet Plant: Recently, the Union Minister for New and Renewable Energy inaugurated a 240-tonnes-per-day biomass pellet plant in Rewari, Haryana, marking a key milestone in the State’s clean energy transition and India’s renewable energy push.

• Key Highlights: The plant uses paddy straw, mustard straw and cotton stalks to produce biomass pellets for co-firing in thermal power plants, helping reduce pollution, carbon emissions, and stubble burning.

• The initiative will boost rural livelihoods, create new income streams for farmers, and support the clean fuel ecosystem.

• National Policy on Biomass Co-firing: GoI has notified a new policy mandating biomass pellet / MSW charcoal co-firing in all coal-based power plants.

• Thermal plants must co-fire 5% biomass nationally; 7% for Delhi-NCR

• At least 50% of biomass for NCR plants must come from local paddy residue & stubble, directly addressing farm burning.

• Government is strengthening source segregation and regulatory systems to support MSW charcoal production despite waste-quality challenges.

• About R21/Matrix-M: The second malaria vaccine to receive a WHO recommendation, following RTS, S/AS01 approved in 2021.

• It was developed by the University of Oxford and is being manufactured and scaled up by the Serum Institute of India (SII).
