1. Indian Council of Agricultural Research: A six-year ICAR study analyzing over 2.5 lakh soil samples from 620 districts has found a significant decline in organic carbon levels in India’s arable soils. The report attributes this reduction largely to climate change and the unbalanced, unscientific use of fertilizers.

• Key Highlights: The research, led by the Indian Institute of Soil Science, confirms that soil organic carbon influences the physical, chemical, and biological properties of soil, and is linked directly to micronutrient availability.
• Soil organic carbon is negatively correlated with temperature; regions with high temperatures (such as Rajasthan and Telangana) have lower carbon content.
• Cropping patterns influence carbon retention: rice-based and pulse-based cropping systems tend to have higher organic carbon, while wheat and coarse-grain systems show lower levels.
• The study developed an “agri-ecological base map” covering 20 agro-ecological regions to analyze impacts of cropping patterns and fertilizer use.
• Regions like Haryana, Punjab, and Western Uttar Pradesh showed a decline in soil carbon due to overuse and imbalance of chemical fertilizers (particularly urea and phosphorus).
• States like Bihar, where fertilizer use is more balanced, show better soil carbon levels.
• Recommendations include: Promote soil coverage with crops year-round and expand plantations.
  • Incentivize farmers who enhance soil carbon sequestration (carbon credit system).
  • Develop region-specific crop and land management strategies for climate change mitigation.

2. Aditya-L1: Recently, Aditya-L1, India’s first space-based solar observatory, delivered the first-ever spectroscopic measurements of a coronal mass ejection (CME) in the visible wavelength range.

• Key Highlights: The observations were made using the Visible Emission Line Coronagraph (VELC) instrument, operated by the Indian Institute of Astrophysics (IIA) in collaboration with NASA.
• The payload’s placement at the Sun–Earth Lagrange Point L1 allows continuous 24-hour observation of the Sun, without interruption.
• Scientists were able to measure key physical parameters of a CME very close to its origin near the Sun’s surface, something not previously possible.
• Estimated properties of the observed CME: Electron density: ~370 million electrons per cubic centimetre (significantly higher than normal corona levels).
• Energy: ~9.4 × 10^21 joules (many orders of magnitude greater than the energy of the Hiroshima and Nagasaki atomic bombs).
• Mass: ~270 million tons (compared to the ~1.5 million-ton iceberg that sank the Titanic).
• Speed: ~264 km per second, Temperature: ~1.8 million Kelvin.
• These measurements help clarify how much mass and energy the Sun loses during CME events, improving understanding of solar activity impacts on space weather.

3. Odd Radio Circle (double ORC): Recently, scientists from India’s RAD@home astronomy network identified a rare twin Odd Radio Circle (double ORC), marking only the second such discovery in the world.

• About Odd Radio Circles: Large, circular radio-emitting structures that are detectable only in radio wavelengths, not in visible, X-ray, or infrared light.
• ORCs are believed to be caused by powerful shockwaves from extreme galactic events, such as black hole mergers or massive energy outflows from galaxy centers.
• First discovered in 2019 using data from the ASKAP telescope in Australia; subsequent studies involved LOFAR and India’s GMRT.
• Key characteristics of ORCs: Appearing as faint, ring-like radio halos.
• Among the largest known cosmic structures, spanning millions of light-years.
• Often have a galaxy located at their center, though some appear isolated.
• The newly discovered twin ORC consists of two opposite expanding plasma rings, likely generated by a major outburst or collision in a host galaxy.
• The discovery provides valuable clues about galactic evolution, black hole-driven phenomena, and intergalactic shockwave processes.

4. Exercise Malabar: Recently, Exercise Malabar has been conducted as a multilateral naval exercise involving the navies of India, the United States, Japan, and Australia.

• About Exercise Malabar: The exercise began in 1992 as a bilateral naval engagement between India and the United States. Japan joined as a permanent member in 2015, followed by Australia in 2020, transforming it into a Quad-level maritime exercise.
• Participating Nations: India, United States, Japan, and Australia — the four countries of the Quadrilateral Security Dialogue (Quad), committed to maintaining a free, open, and rules-based Indo-Pacific region.
• Host for 2025: Malabar 2025 is being conducted at Guam, a U.S. territory in the Western Pacific, and includes both harbour and sea phases.
• Features of Malabar 2025: Harbour Phase: Operational planning sessions, communication coordination, familiarisation visits among naval contingents, and cultural and sports exchanges to build professional and personal rapport.
• Sea Phase: Complex naval operations such as joint fleet manoeuvres, anti-submarine warfare exercises, surface gunnery drills, air defence operations, and cross-deck helicopter missions to enhance integrated warfighting capabilities.
• India’s Participation: INS Sahyadri, an indigenously designed and built stealth-guided missile frigate, represents India in Malabar 2025.

5. NALSAR University Report: Recently, Supreme Court Justice Vikram Nath highlighted that more than 70% of India’s prison population consists of under-trials, many of whom are unaware of their right to free legal aid, as noted in a NALSAR University report on fair trial practices.

• Key Highlights: 3% of under-trials had no legal representation, and over 51% did not have access to essential case documents.
• 68% of under-trials belonged to marginalised caste groups, and 80% were employed in the unorganised sector, indicating strong socio-economic vulnerability.
• 58% of accused persons had at least one disability, reflecting layered and intersectional disadvantage.
• Only 91% accessed free legal aid, despite constitutional and statutory guarantees under Article 21 and Article 39A.
• The programme filed 1,834 bail petitions, securing 1,388 releases and conclusion of 777 cases, showing that structured legal support significantly improves outcomes.
• The report exposes systemic gaps in the justice system, leading to pre-trial detention functioning as punishment before conviction.
• Calls for urgent reforms in legal aid delivery, bail procedures, and pre-trial detention policies to ensure fair trial rights.

6. COP30: Recently, COP30, the 30th UN Climate Conference under the UNFCCC, has been designated to assess and strengthen global climate action. It will take place in Belém, Brazil, in the Amazon region, highlighting the vital role of tropical forests in climate mitigation.

• Key Highlights: The conference marks 10 years since the Paris Agreement, shifting focus from promises to implementation.
• Central principle guiding negotiations: Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC), emphasizing equity for developing nations.
• Global Stocktake (GST): First major assessment of global progress on climate goals to identify gaps in emissions reduction and adaptation efforts.
