Science: The Nobel Prize in Physics 2024 (announced 8 October) for John Hopfield and Geoffrey Hinton dominated science coverage. India's MACE telescope at Hanle, Ladakh, was flagged as the world's highest imaging Cherenkov telescope.
Global Governance: The Global Digital Compact, adopted at the UN Summit of the Future, created two new AI governance panels.
Health: India was declared free of trachoma by the WHO. India is only the third country in the WHO South-East Asia Region to achieve this milestone.
Environment: The 2023 deforestation report showed 15.7 million acres of forest lost globally, with Bolivia seeing a 351 per cent increase since 2015.
1. India eliminates trachoma
GS area: Health, Governance
The World Health Organisation formally declared India free of trachoma as a public health problem. Trachoma is a bacterial eye infection and one of the leading infectious causes of preventable blindness.
The disease: Caused by the bacterium Chlamydia trachomatis. Repeated infections scar the inside of the eyelid. Eventually the eyelid turns inward and the eyelashes scratch the cornea with every blink, causing blindness.
Transmission: Through contact with eye and nose secretions of infected individuals, and through flies that feed on secretions.
Elimination threshold: WHO defines elimination as a public health problem as fewer than 5 per cent prevalence of active infection in children aged 1 to 9, and fewer than 0.2 per cent of adults with trichiasis (the late-stage eyelid turning).
India's achievement: India is the third country in the WHO South-East Asia Region to reach elimination, after Nepal and Myanmar.
SAFE strategy: The WHO-recommended approach stands for Surgery (corrective eyelid), Antibiotics (azithromycin), Facial cleanliness, and Environmental improvement (sanitation and water access). India applied this strategy across endemic districts.
Static linkage: Neglected tropical diseases, WHO elimination programmes, public health (Science and Health).
2. Global Digital Compact (GDC)
GS area: International Relations, Governance (Digital Policy)
The UN General Assembly adopted the Global Digital Compact at the Summit of the Future in September 2024. Its provisions began being discussed in implementation forums in October.
Nature: A non-binding diplomatic instrument. It does not create legal obligations but sets norms and frameworks for international cooperation on digital governance.
Two new bodies created:
The Independent International Scientific Panel on AI: An expert body to assess AI's capabilities, risks, and opportunities.
Global Dialogue on AI Governance: A forum for member states to exchange views and build policy convergence on AI regulation.
Core concerns addressed: The digital divide (unequal access to internet and technology), data privacy, cybersecurity, and ethical AI deployment.
Criticism: The compact relies on self-regulation by technology companies. It does not establish a binding enforcement mechanism. Large technology companies primarily headquartered in the United States and China continue to operate under national rather than international rules.
Static linkage: UN governance bodies, digital divide, AI regulation (International Relations).
3. Nobel Prize in Physics 2024: implications for India
GS area: Science and Technology
Following the announcement of the Physics Nobel for Hopfield and Hinton on 8 October, analysis focused on India's position in AI and physics research.
MACE Telescope (Major Atmospheric Cherenkov Experiment): Located at Hanle in Ladakh at 4,300 metres, it is the world's highest imaging Cherenkov telescope. It detects very high energy gamma rays from cosmic sources through the Cherenkov radiation they produce in the atmosphere. It is relevant for research into dark matter, cosmic ray acceleration, and fundamental physics.
India's AI research position: India contributes fewer than 3 per cent of globally cited AI research papers but houses one of the world's largest pools of AI engineering talent. The gap between engineering capacity and foundational research is a policy concern.
Indian Wild Ass population: A separate wildlife census released the same week found the Indian Wild Ass population reached 7,672 in 2024, a 26.14 per cent increase from 2020. Indian Wild Asses are found only in the Little Rann of Kutch, Gujarat.
Static linkage: Indian space and physics research, wildlife, astronomy (Science and Technology).
4. India Textile Sector
GS area: Economy (Industry)
A review of India's textile sector outlined both its scale and its challenges ahead of target-setting for 2030.
Current market size: 153 billion dollars (2021). The target is 350 billion dollars by 2030.
Global position: India is the third-largest textile exporter globally, with a 5.4 per cent share of world trade. China holds over 30 per cent.
Employment: The sector directly and indirectly employs 105 million people, making it the second-largest employer after agriculture.
FY24 performance: Exports declined due to high raw material costs, a 10 per cent cotton import duty, and supply chain disruptions. Major competitors in Southeast Asia benefit from lower cotton import duties.
Key schemes: ATUFS (Amended Technology Upgradation Fund Scheme), SITP (Scheme for Integrated Textile Parks), SAMARTH (skill development), PM-MITRA (Mega Integrated Textile Region and Apparel Parks).
Annual deforestation data for 2023 showed that 15.7 million acres of forest were lost globally.
Global context: This is an area roughly the size of Ireland. Tropical deforestation is the second-largest source of greenhouse gas emissions after fossil fuel combustion.
Bolivia's anomaly: Bolivia saw a 351 per cent increase in deforestation between 2015 and 2023. The primary driver is the expansion of soybean and cattle ranching into the Chiquitano dry forest and parts of the Amazon.
Other major losers: Brazil's Amazon losses continued despite policy changes. The Congo Basin in Africa recorded high losses.
Why it matters for India: India's own forests are under pressure. The Forest Conservation Amendment Act of 2023 and fast-tracked clearances for the Northeast raise similar concerns about protecting the country's forest carbon stock.
Scientists using the James Webb Space Telescope detected carbon dioxide and hydrogen peroxide on Charon, the largest moon of Pluto.
What Charon is: The largest of Pluto's five known moons. At about 1,200 kilometres in diameter it is unusually large relative to Pluto, making the Pluto-Charon system sometimes described as a double dwarf planet system.
CO₂ detection significance: Carbon dioxide ice on Charon's surface suggests chemical processes or material exchange with Pluto or the wider Kuiper Belt environment.
Hydrogen peroxide: Its presence points to radiation-driven chemistry on the surface, where high-energy particles from the sun break apart water molecules to form peroxide compounds.
James Webb Space Telescope: NASA's infrared space telescope launched in December 2021. It can observe extremely distant and cold objects with unprecedented sensitivity.
Static linkage: Planetary science, JWST, outer solar system (Science and Technology).
