The Ministry of Electronics and Information Technology is examining a separate, standalone law to regulate artificial intelligence in India, rather than continuing to govern AI through the Information Technology Act, 2000. Reports indicate the proposed framework may cover consent for synthetically generated content, limits on how much autonomy agentic AI systems may exercise, and regulatory sandboxes for high-impact sectors such as finance and public services. Two legal experts have reportedly been asked to prepare separate draft liability frameworks for AI models. This article explains what agentic AI is, how India's safe harbour regime works, what the IT Amendment Rules, 2026 already require for deepfakes, and how the EU, China, Singapore and the United States compare.

Skyroot Aerospace's Vikram-1, India's first privately developed orbital launch vehicle, successfully placed technology demonstration satellites in Low Earth Orbit (LEO) from Sriharikota on July 18, 2026, making India only the third country after the US and China with private orbital launch capability. This article explains the Vikram-1 mission and Skyroot Aerospace, what Low Earth Orbit is, how orbital slots and radio frequencies are governed under the Outer Space Treaty and the ITU, the global race for LEO and satellite megaconstellations, India's space sector reforms, IN-SPACe and the Indian Space Policy 2023, the strategic significance of sovereign launch capacity, and the bottlenecks ahead — with UPSC Prelims facts, MCQs and Mains practice questions.

China test-fired a submarine-launched intercontinental ballistic missile from the South China Sea into the Southern Pacific Ocean on 6 July 2026 — its first-ever SLBM launch into international waters and only its second ballistic missile test in international waters since 1980. The missile, believed to be the JL-2 or JL-3, flew over the Philippines and landed in the South Pacific nuclear-free zone, drawing protests from the US, Japan, Australia and Pacific island nations. This article explains ballistic missile basics, the JL missile family, China's nuclear triad and evolving nuclear strategy, the Treaty of Rarotonga, and the implications for India's nuclear deterrent and the Indo-Pacific.

Pfizer has reported mid-stage clinical-trial results for berobenatide, an investigational GLP-1 receptor agonist being studied as a possible once-monthly obesity injection. The development is important for UPSC because it connects biotechnology, chronic disease management, clinical-trial regulation, public health policy, India’s rising obesity burden and ethical questions around access to expensive weight-loss medicines.

In a first of its kind, the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS) launched the SMILE mission (Solar wind Magnetosphere Ionosphere Link Explorer) on 19 May 2026 aboard a Vega-C rocket to study Earth's magnetic shield against the Sun. SMILE will capture the first-ever X-ray images of the magnetosphere. This article explains the SMILE mission, Earth's magnetosphere, solar wind, geomagnetic storms, auroras, space weather, the four science instruments, the highly elliptical orbit, and how it links to India's Aditya-L1 — everything UPSC aspirants need on this landmark space-science mission.

The 2025 Nobel Prize in Physiology or Medicine has been awarded to Japanese scientist Shimon Sakaguchi and American scientists Mary E. Brunkow and Frederick J. Ramsdell for their pioneering discoveries on regulatory T cells. These cells act as essential "security guards" in the immune system, ensuring it fights off harmful invaders like viruses and bacteria without mistakenly attacking the body's own healthy cells. This breakthrough, announced by the Nobel Committee, highlights the mechanism of peripheral immune tolerance and opens new pathways for treating autoimmune diseases and enhancing cancer therapies, addressing a long-standing puzzle in immunology.
