• Internal security: The US designated The Resistance Front (TRF), a Lashkar-e-Taiba offshoot active in J&K, as a Foreign Terrorist Organization, freezing its assets globally.
• Culture: Gangaikonda Cholapuram, Rajendra Chola I's capital built after conquering the Gangetic plains, is a UNESCO World Heritage site.
• Biodiversity: A new crustose lichen species named Allographa effusosoredica was discovered in the Western Ghats, the first Indian Allographa to be sequenced using molecular markers.
• Trade: Port of Eilat, Israel's only Red Sea port, has seen maritime activity collapse by over 90 per cent due to Houthi attacks.
• Health: The US is experiencing its worst measles outbreak since 1992, with 1,300-plus cases across 39 states. Herd immunity requires 95 per cent vaccine coverage; the US rate is 92.7 per cent.

Attacks on migrant workers in Bengaluru and Mumbai reignited the debate over linguistic identity and internal migration.

• Eighth Schedule: India recognises 22 official languages under the Eighth Schedule of the Constitution. There are 1,600-plus mother tongues.
• The tension: Local language can be a marker of belonging and economic access. It can also become a tool for excluding migrants from services, jobs and civic life.
• Constitutional protection: Article 19(1)(d) and (e) guarantee every citizen the right to move freely and reside in any part of India. Discrimination against internal migrants based on language or place of birth violates Article 15.
• Historical pattern: Sons-of-the-soil politics has recurred in Maharashtra (Marathi vs. migrants), Karnataka (Kannada preference in employment) and Tamil Nadu (anti-Hindi agitations).
• Democratic concern: When political parties mobilise identity for electoral gain, the Supreme Court has treated it as comparable to communalism in its threat to national integration (as noted on 16 July 2025).

The Air India Ahmedabad accident reignited debate on pilot mental health screening in civil aviation.

• Mental Healthcare Act, 2017: Establishes the right to access mental health care and prohibits discrimination on grounds of mental illness. Relevant to employment protections.
• Tele-MANAS helpline: Government's 24/7 mental health helpline at 14416. Operates in 767 districts under the District Mental Health Programme.
• WHO estimate: 1 dollar spent on mental health treatment yields 4 dollars in economic productivity.
• Aviation context: Most civil aviation authorities mandate regular psychological assessment for pilots. India's DGCA framework requires periodic medical certification.
• National suicide prevention target: A 10 per cent reduction by 2030.

GS area: History (medieval India, Chola Empire)

Gangaikonda Cholapuram was the imperial capital of the Chola dynasty from 1025 to 1279 CE.

• Founder: Rajendra Chola I, who built the city after his victorious north Indian campaign that reached the Gangetic plains. The name translates as "the Chola who conquered the Ganges."
• Location: Ariyalur district, Tamil Nadu.
• Architecture: The Brihadisvara Temple, built by Rajendra Chola I, is the main monument. It is a UNESCO World Heritage Site as part of the "Great Living Chola Temples" inscription.
• Chola reach: The empire extended from the Tungabhadra River in the north to Sri Lanka in the south. Naval expeditions reached Southeast Asia.
• World Heritage status: The Chola temples (Brihadisvara at Thanjavur, Gangaikonda Cholapuram and Airavatesvara at Darasuram) are collectively inscribed.

GS area: Internal Security, International Relations

The United States designated The Resistance Front (TRF) as a Foreign Terrorist Organisation (FTO) and Specially Designated Global Terrorist (SDGT).

• What TRF is: An offshoot of Lashkar-e-Taiba (LeT), created in 2019-2020 after the revocation of Jammu and Kashmir's special status under Article 370.
• Operational area: Jammu and Kashmir. TRF has claimed several attacks in the Valley.
• Effect of FTO designation: Freezes all US-based assets, makes providing material support a criminal offence under US law, restricts travel and global financial operations.
• India's perspective: TRF is seen as a "rebranding" by Pakistan-based groups to provide deniability for cross-border terrorism post-Article 370.

The CMA-6 (Conference of the Parties serving as the Meeting of the Parties to the Paris Agreement) welcomed the 2024 report of the Sharm el-Sheikh Dialogue.

• What the Dialogue is: A formal dialogue platform under the Paris Agreement established at COP27 in Sharm el-Sheikh (2022). Its mandate flows from Decision 1/CMA.4.
• Purpose: Align global finance flows with climate goals as required by Article 2.1(c) of the Paris Agreement.
• Format: Minimum two workshops annually, co-chaired by a developed and a developing country representative.
• Participants: UNFCCC parties, financial entities, NGOs and private sector.
• Significance: Climate finance is the central unresolved tension at every COP. The Sharm el-Sheikh Dialogue is the dedicated process for keeping finance alignment on the official agenda between COPs.

GS area: Environment (biodiversity)

Researchers discovered a new crustose lichen species in the Western Ghats, named Allographa effusosoredica. It is the first Indian Allographa species to be sequenced using molecular markers.

• What a crustose lichen is: A lichen that grows as a flat crust directly on rock, bark or soil surface, with no lower cortex that can be separated.
• Symbiosis: Lichens are a symbiosis between fungi and photosynthetic partners (algae or cyanobacteria). This species contains the algal partner Trentepohlia.
• Chemical marker: Contains norstictic acid, a unique metabolite.
• Significance: India now has 53 known Allographa species; 22 from the Western Ghats alone. Molecular sequencing allows detection of cryptic species that appear identical to the eye.

GS area: Science and Technology (nuclear medicine, health)

Radioactive iodine (Iodine-131) was discovered in 1938 by Glenn Seaborg and John Livingood. It remains a standard treatment for thyroid disease.

• Applications: First-line treatment for hyperthyroidism and differentiated thyroid cancer.
• Mechanism: The thyroid preferentially absorbs iodine. When radioactive I-131 is ingested, it accumulates in thyroid cells and beta radiation destroys them.
• Administration: Patients ingest a capsule or liquid. No external exposure to others if standard precautions are followed.
• Contraindication: Absolutely contraindicated in pregnancy, as it crosses the placenta and destroys the fetal thyroid.

GS area: International Relations (West Asia, trade routes)

The Port of Eilat is Israel's only commercial port on the Red Sea. Houthi attacks have collapsed maritime activity by over 90 per cent.

• Location: On the Gulf of Aqaba, which connects to the Red Sea.
• Operational history: Operational since 1957.
• Strategic function: Serves as Israel's bypass route around Egypt (Suez Canal) for Asian trade. Handles 50 per cent of Israeli vehicle imports from Asia.
• Houthi impact: The Houthi missile and drone campaign targeting Israeli-linked shipping in the Red Sea has made the route economically unviable.
• India link: Indian seafarers and Indian-flagged vessels have faced risk in the Red Sea corridor, connecting to the broader West Asia conflict impact on Indian trade.
