The U.S.–Iran Preliminary Peace Accord 2026

Core Context: The United States and Iran announced a breakthrough preliminary agreement to halt their active military conflict and lift the naval blockade on the strategically vital Strait of Hormuz and the Gulf of Oman. Importantly, this is not a final treaty but an emergency memorandum of understanding — essentially a 60-day de-escalation mechanism designed to stop a hot war and prevent a global energy collapse. The roots of the crisis lie in the breakdown of the 2015 nuclear deal, which had restricted Iran's nuclear programme in exchange for sanctions relief; its collapse revived deep mistrust that eventually spilled over into direct confrontation between the U.S., Israel and Iran in early 2026. Because the Strait of Hormuz carries a large share of the world's oil and liquefied natural gas, Iran's control over it threatened the entire global energy supply, and the American counter-blockade pushed prices sharply higher.

Latest Developments: The accord mandates an immediate and permanent ceasefire across all war fronts, including proxy theatres such as Lebanon. The U.S. terminates its naval blockade while Iran allows open, toll-free passage of international commercial shipping through the Strait and begins mine-clearing operations. A strict 60-day window has been set for diplomats to negotiate the harder questions of nuclear enrichment and long-term sanctions. The text also provides for the phased unfreezing of about twenty-four billion dollars in Iranian assets and an American commitment to a war-reparations mechanism. Markets reacted instantly, with Brent crude falling around five percent to roughly eighty-three dollars a barrel, while shippers prepared to release crude and LNG stranded on vessels in the Gulf. Risks remain real: the two sides disagree on the sequence of asset release versus nuclear talks, non-state actors in Lebanon and Yemen could derail the truce, damaged oil fields will take months to restart, and the memory of the United States walking out of the 2015 deal leaves a deep trust deficit.

UPSC Prelims Angle: Remember that the Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and onward to the Arabian Sea, and that the Gulf of Oman lies to its south-east — a favourite map-based question. Note the JCPOA as the 2015 nuclear agreement, and link India's interests to lower import bills, safer energy transit and projects like the India–Middle East–Europe Economic Corridor (IMEC) and the I2U2 grouping that help reduce dependence on vulnerable chokepoints.

Planetary Climate Vital Signs Report 2026

Core Context: A new global climate assessment released during the Bonn Climate Change Conference warns that every major planetary climate indicator has deteriorated since the last major scientific assessment cycle. Published in a peer-reviewed Earth-system journal by around seventy scientists from seventeen countries, the report is meant to give policymakers near real-time evidence on warming, greenhouse gases and climate extremes in the gap between the large periodic global assessments.

Latest Developments: All eleven indicators studied recorded worsening conditions. Marine heatwaves showed the sharpest rise and are now the fastest-worsening indicator, while the Earth's energy imbalance — the rate at which the planet is accumulating heat — also climbed to record levels. Human-induced warming reached about 1.37°C above pre-industrial levels in 2025, greenhouse-gas emissions touched an all-time high of roughly eighty billion tonnes of carbon-dioxide-equivalent, and the assessment cautions that the world could cross the Paris Agreement's 1.5°C limit within approximately four years on current trends. Of particular concern for India, the Indian Ocean is approaching a near-permanent marine-heatwave state, with projections of two hundred to two hundred fifty heatwave days a year by 2100 against around twenty days historically — a shift that could disrupt the monsoon, intensify cyclones and worsen heat stress across the subcontinent.

UPSC Prelims Angle: Connect the 1.5°C and 2°C thresholds to the Paris Agreement of 2015, recall that the Conference of the Parties holds intersessional technical meetings in Bonn, and be ready to link marine heatwaves, coral bleaching and monsoon variability as cause-and-effect chains in environment questions.

Project Great Indian Bustard: Three New Chicks

Core Context: The Great Indian Bustard, one of the heaviest flying birds in the world, is a flagship indicator species for the health of India's grassland and semi-arid ecosystems. With its wild population now largely confined to Rajasthan, especially the Desert National Park near Jaisalmer, every successful birth matters for the species' survival.

Latest Developments: The Environment Ministry announced that the conservation breeding programme for the Great Indian Bustard has successfully added three more chicks. The bird's natural recovery is painfully slow because females usually lay just a single egg a year directly on open ground, leaving it exposed to foxes, dogs and crows. In the wild, the leading cause of death is collision with high-voltage overhead power lines, since the bird has poor frontal vision — which is why conservationists have pushed for underground cabling and bird diverters in its habitat.

UPSC Prelims Angle: Fix the key tags firmly — the Great Indian Bustard (Ardeotis nigriceps) is Critically Endangered on the IUCN Red List, listed in Schedule I of the Wild Life (Protection) Act, 1972, and in Appendix I of CITES. It is the state bird of Rajasthan, and 'Project GIB' along with captive breeding centres are recurring scheme-based facts.

The 52nd G7 Summit at Evian

Core Context: The Group of Seven is an informal forum of the world's most advanced industrialised economies that coordinates responses to major global economic and political challenges. India is not a member but is a frequent special invitee, reflecting its growing diplomatic weight.

Latest Developments: The Prime Minister arrived in Evian, France, to take part in the 52nd G7 Summit held from the fifteenth to the seventeenth of June 2026 under the French presidency, on an invitation from President Emmanuel Macron. This marks India's thirteenth overall and seventh consecutive appearance at the summit. The 2026 agenda leaned heavily on the safe and ethical governance of artificial intelligence, alongside the usual themes of macroeconomic coordination and geopolitical crisis management. The Prime Minister's wider diplomatic outreach also brought a clutch of top civilian honours: the Order of the White Double Cross, First Class, from Slovakia — that country's highest state decoration, instituted in 1994 after the peaceful split of Czechoslovakia — as well as the Dominica Award of Honour, Guyana's Order of Excellence and the Honorary Freedom of Barbados.

UPSC Prelims Angle: Memorise the seven members — Canada, France, Germany, Italy, Japan, the United Kingdom and the United States — with the European Union as a participating member. Recall that the grouping became the G8 with Russia in 1998 and reverted to the G7 in 2014, and that the 2026 invitees were India, China, South Korea, Kenya and Brazil, with the United States hosting in 2027.

WT-MARUT: India's First Wind Turbine Supply-Chain Portal

Core Context: India has installed about 56.1 GW of wind capacity but has tapped only a fraction of its estimated 1,164 GW potential, and it aims for 100 GW of wind capacity by 2030. Strengthening the domestic manufacturing ecosystem is central to that goal, and a coordinated digital backbone for the supply chain had been missing.

Latest Developments: The Ministry of New and Renewable Energy launched WT-MARUT, the country's first indigenous, centralised platform dedicated to managing and optimising the wind-turbine manufacturing supply chain, unveiled at the Global Wind Day conference in Goa. The portal offers end-to-end visibility of the component network, helps developers discover and qualify suppliers, eases compliance with domestic-sourcing rules under the Approved List of Models and Manufacturers framework, and includes export-readiness analytics. With wind-equipment exports already crossing twelve thousand crore rupees in 2025–26, the portal supports India's ambition to capture a tenth of global wind-turbine exports by 2030.

UPSC Prelims Angle: Tie WT-MARUT to the Ministry of New and Renewable Energy and to the ALMM framework, which is the same domestic-sourcing tool used in the solar sector. Global Wind Day is observed on the fifteenth of June, a handy date-based fact.

The DengiAll Dengue Vaccine and Vaccine-Safety Concerns

Core Context: Dengue is caused by a mosquito-borne virus that exists in four distinct serotypes, so an effective vaccine must be tetravalent — it has to protect against all four strains at once. India's indigenous candidate, DengiAll, developed by Panacea Biotec with the Indian Council of Medical Research, has been a closely watched project.

Latest Developments: The suspension of Brazil's dengue vaccination campaign in early June, following serious adverse events and two deaths linked to the Butantan-DV vaccine, has sharpened safety scrutiny of India's upcoming DengiAll, whose Phase 3 trials completed enrolment in January 2026 and now await data analysis for regulatory approval. Both DengiAll and Butantan-DV use a live-attenuated platform built on the same backbone, which makes the Brazilian experience directly relevant. A key scientific worry is antibody-dependent enhancement, where weakly binding antibodies can actually help the virus enter cells and worsen a later infection — the central reason dengue vaccines are so difficult to design.

UPSC Prelims Angle: Distinguish the leading vaccines — DengiAll (Panacea Biotec–ICMR), Butantan-DV (Brazil), Qdenga (Takeda, Japan) and the older Dengvaxia (Sanofi). Remember dengue spreads mainly through the Aedes aegypti mosquito, which also transmits chikungunya and Zika, and understand 'live-attenuated' and 'tetravalent' as core concepts.

India's Multi-Layered Ballistic Missile Defence System

Core Context: A Ballistic Missile Defence system is an automated network of long-range radars, command centres and interceptor missiles designed to detect, track and destroy incoming hostile missiles — in effect a protective shield over cities and strategic installations, often described as India's indigenous answer to systems like Israel's Iron Dome.

Latest Developments: The Defence Research and Development Organisation carried out three consecutive flight tests to demonstrate a multi-layered defence capability, completing the second phase of India's BMD programme and placing the country in an elite group able to neutralise long-range missiles. The architecture is tiered by altitude, with exo-atmospheric interceptors operating in the upper atmosphere and outer space and endo-atmospheric interceptors working below roughly a hundred kilometres. The advanced interceptors are rated against intermediate-range threats at distances of two thousand to five thousand kilometres, and the tests were accompanied by the Naval Anti-Ship Missile (Medium Range) for sea-skimming maritime targets.

UPSC Prelims Angle: Note that the elite group with credible BMD capability includes the United States, Russia, China, Israel and India. Be clear on the difference between exo-atmospheric (outside the atmosphere) and endo-atmospheric (within the atmosphere) interception, and link the programme to DRDO.

NCERT and the 'Dancing Girl' of Mohenjo-daro

Core Context: The Dancing Girl is one of the most celebrated artefacts of the Indus Valley Civilisation — a small bronze statuette, only about ten centimetres tall, unearthed at Mohenjo-daro in 1926 by John Marshall, who named it for the dancer-like pose. It is dated to around 2500 BCE and is housed in the National Museum in New Delhi.

Latest Developments: The National Council of Educational Research and Training announced it will replace a retouched image of the figurine in its new Class 9 art textbook, after the altered picture drew criticism for covering up the original sculpture. The episode has renewed attention on the artefact's significance: it showcases the Harappan mastery of the lost-wax casting technique and bronze metallurgy, and its natural, weight-shifted stance — known in art history as contrapposto — along with its asymmetric bangles makes it a unique example of Indus craftsmanship.

UPSC Prelims Angle: Remember that the Dancing Girl is made of bronze using the lost-wax (cire-perdue) technique, unlike most Harappan human figures, which are terracotta. Mohenjo-daro lies on the Indus in present-day Sindh, Pakistan, and is famous for the Great Bath and the Granary — recurring culture questions.

Trademark Protection for the Shree Jagannath Temple

Core Context: The Shree Jagannath Temple at Puri, Odisha, dedicated to Lord Jagannath — a synthesised form of Vishnu and Krishna — is one of the Char Dham pilgrimage sites. The present temple was built in the twelfth century by the Eastern Ganga ruler Anantavarman Chodaganga Deva, and the site is historically known as Purushottama Kshetra or Nilachala, the Blue Mountain.

Latest Developments: The Shree Jagannath Temple Administration secured wordmark registrations for the terms 'Ananda Bajara' and 'Patitapabana' and a logomark registration for the sacred Nilachakra emblem under the trademarks law, a move aimed at protecting the temple's intellectual property and preventing unauthorised commercial use of its sacred identity.

UPSC Prelims Angle: Recall that the holy trinity on the Ratnabedi comprises Lord Jagannath, Balabhadra and Subhadra along with the Sudarshana Chakra, that the idols are carved from neem wood, and that temple administration is governed by the Shri Jagannath Temple Act of 1955 with the Gajapati Maharaja as head. The Rath Yatra at Puri is a frequently tested cultural event.
