• Prey Base: Sustains a healthy population of chital, sambar deer, barking deer, and nilgai.

• Project Cheetah aims to re-establish the cheetah in India after its disappearance from the country.
• The Asiatic cheetah was declared extinct in India in 1952.
• The programme is overseen by the National Tiger Conservation Authority, with technical support from the Wildlife Institute of India.
• Its main objectives are:
  • Re-establishing the ecological role of the cheetah.
  • Restoring and protecting grassland and open natural ecosystems.
  • Conserving prey species and other associated wildlife.
  • Contributing to global cheetah conservation.
  • Improving livelihood and tourism opportunities for local communities.

• 28 February 2026: Nine cheetahs arrived from Botswana.
• The NTCA describes the programme as an international conservation effort to restore the species to its former Indian range.

• India’s total cheetah population had reached 52 by 17 September 2026.
• Of these, 49 were in Kuno National Park and 3 in Gandhi Sagar Wildlife Sanctuary.
• At that stage, 17 cheetahs in Kuno were in the wild.
• 32 cheetahs were in soft-release bomas, including 19 cubs below one year of age.
• The population included cheetahs from Namibia, South Africa and Botswana, along with their India-born offspring.

• Colonial Genesis: It was established in 1891 as the Imperial Secretariat Library in Calcutta (now Kolkata).
• Capital Shifts: Following King George V's 1911 announcement to shift British India's capital to Delhi, the library moved to the Old Secretariat Building in Civil Lines in 1912. It later moved to the North Block in the 1930s.
• Current Base: It has been housed in the G-Wing of Shastri Bhawan, New Delhi, since 1969.
• Post-Independence: The institution was formally renamed the Central Secretariat Library in 1948.

• Rank by Size: It is the second largest Central Government library in India, right after the National Library in Kolkata.
• Administrative Ministry: It is funded and entirely administered by the Ministry of Culture, Government of India.
• Branches: Besides the main facility, it operates a dedicated Hindi regional languages wing (Tulsi Sadan Library) and a text book library branch located at R.K. Puram, New Delhi.

• Total Volume: The library houses over 8.5 lakh (850,000) print and non-print volumes, including official records, gazettes, and research papers.
• Historical and Rare Books: It guards a dedicated section of 6,500 rare documents. Its oldest book is a compilation of a French traveller's writings dating back to 1702.
• Official Documents: It hosts an Indian Official Document Division (80,000 bound volumes), a Foreign Official Document Division (60,000 documents), a Serials Division (52 newspapers, 226 periodicals), and a microfilm unit.

• Government Repository: CSL functions as the central "working archive" or record room of the Indian state, storing vital institutional memory and past government decisions.
• Core Beneficiaries: While it primarily satisfies the internal research and information needs of all Union ministries and departments, its resources are also heavily utilized by research scholars and students preparing for competitive exams.

• Scientific Classification: Scientifically known as Hoplocerambyx spinicornis, it is an aggressive, wood-boring beetle belonging to the order Coleoptera and family Cerambycidae.
• Physical Appearance: The adult insect is dark brown, roughly the size of a human finger, and possesses long antennae (which are longer in males than in females).
• Historical Threat: It was first identified as a major destructive threat to Indian forests in 1897.

• Destructive Larval Stage: While adult beetles lay 100 to 300 eggs during the monsoon (June–July), it is the white grubs (larvae) that cause catastrophic damage.
• Killing Mechanism: The larvae spend roughly 11 months inside the tree. They bore through the bark, tunnel extensively into the sapwood, and penetrate deep into the heartwood. This internal hacking completely destroys the vascular sap pathways, depriving the tree of nutrients and killing it.
• Signs of Infestation: Affected trees can be visually identified by the browning and falling of their crown foliage, boreholes in the trunk, and massive heaps of wood dust (sawdust) accumulating at the base of the tree.

• Climatic Factors: Extended periods of heavy monsoon rainfall and high humidity levels create the perfect breeding ground for larval proliferation.
• Natural Cyclical Patterns: Sal borer outbreaks frequently follow a 30-year natural cycle, with the current 2026–2027 surge mimicking previous devastating epidemics from 1923–1928 and 1996–2002.
• Tree Vulnerability: Older trees with a higher volume of heartwood, monotypic stands, and overall poor forest hygiene make the ecosystem highly susceptible to rapid transmission.

• Threat to Livelihoods: Local indigenous communities, such as the Gond and Baiga tribes, heavily rely on Sal trees (Shorea robusta) for collecting seeds, oil, resin (used as dhoop), and leaves. Mass felling strips away their primary source of income.
• Environmental Degradation: Large-scale logging threatens the immediate canopy cover, risks topsoil erosion across the Maikal Hills, and alters crucial regional watersheds.
• Habitat Fragmentation: Sal forests make up the core habitat inside critical Central Indian tiger reserves like Kanha and Pench. Massive canopy loss risks disrupting the local wildlife food chain.

• The "Trap-Tree" Method: Because chemical insecticides are completely ineffective once larvae enter the heartwood, foresters use a non-toxic alternative. Freshly cut Sal logs are placed intentionally around the forest; the oozing sap acts as a natural lure (kairomone), attracting adult beetles so they can be manually gathered and destroyed.
• Sanitation Felling: Removing and cutting down heavily infested dying trees is a necessary "mechanical block" to break the pest's reproductive cycle and prevent emerging beetles from spreading to healthy trees.
• Long-Term Solutions: Conservation scientists recommend shifting forest management away from vulnerable monocultures toward resilient, mixed-canopy forests, alongside preserving avian predators that hunt the beetles naturally.

• Genetic Mutation: Sickle Cell Anaemia (SCA) is an autosomal recessive genetic disorder caused by a point mutation in the HBB gene on chromosome 11.
• Defective Haemoglobin: This mutation causes the body to produce abnormal haemoglobin known as Haemoglobin S (HbS) instead of normal Haemoglobin A (HbA).
• Disease vs. Trait:
  • If a person inherits the mutated gene from both parents, they develop Sickle Cell Anaemia (SCA).
  • If they inherit it from only one parent, they have the Sickle Cell Trait (SCT). They are healthy carriers who usually show no symptoms but can pass the gene to their children.

• Sickle-Shaped Cells: Under low oxygen conditions, the red blood cells become rigid, sticky, and shaped like sickles or crescent moons, instead of being round and flexible.
• Vaso-occlusive Crises (Severe Pain): The rigid cells get stuck in tiny capillaries, blocking blood flow. This cuts off oxygen to tissues, causing sudden, excruciating pain attacks called "crises" in the bones, chest, and abdomen.
• Chronic Anaemia: Normal red blood cells live for 120 days. Sickle cells are fragile and break down (haemolyze) in just 10 to 20 days, leaving the patient chronically short of red blood cells, causing severe fatigue and pale skin.
• Dactylitis: Painful swelling of the hands and feet, which is often the earliest visible sign in infants.
• Organ Damage: Repeated blockages can cause silent strokes, acute chest syndrome, and permanent damage to vital organs like the liver, kidneys, and spleen.

• Solubility Test: A quick, preliminary screening test to see if cells sickle under reduced oxygen.
• High-Performance Liquid Chromatography (HPLC): Used to isolate and accurately measure the exact percentages of normal and abnormal haemoglobin variants in the blood.
• Haemoglobin Electrophoresis: Another gold-standard laboratory technique used to confirm the presence of HbS.

• Pneumococcal Vaccines: As highlighted by the Odisha launch, keeping patients updated on pneumococcal and influenza vaccines is critical to preventing deadly secondary infections.
• Hydroxyurea: A foundational daily oral medication that prompts the body to produce Fetal Haemoglobin (HbF). HbF prevents cells from warping into the sickle shape, drastically reducing pain crises.
• Blood Transfusions: Used during emergencies (like a stroke or acute chest syndrome) to quickly increase the count of normal donor red blood cells.
• Curative Options: Bone Marrow (Stem Cell) Transplants and cutting-edge CRISPR-gene therapies can cure the disease, but they are incredibly expensive, require highly specific matching donors, and are currently inaccessible to the vast majority of rural patients.

• High-Burden Communities: In India, the disease heavily impacts rural, marginalized, and tribal populations due to historical endogamy (marrying within the same community).
• The Malaria Connection: The genetic mutation originally persisted through evolution because individuals with the Sickle Cell Trait (carriers) possess a natural resistance to severe malaria. Consequently, the disease is heavily clustered in historically malaria-prone tropical regions across Africa, the Middle East, and India.

• An Exclave: Kaliningrad is an exclave, meaning it is a portion of Russian territory entirely separated from mainland Russia.
• Location: It sits on the Baltic Sea coast and is wedged directly between two NATO and European Union members: Poland to the south and Lithuania to the north and east.
• Ice-Free Port: It is home to Baltiysk, Russia’s only port on the Baltic Sea that remains completely ice-free year-round, giving it immense economic and naval value.
• The Suwałki Gap: Located just southeast of Kaliningrad is the Suwałki Gap—a narrow 100-kilometer border corridor between Poland and Lithuania. It is considered one of NATO's most vulnerable bottlenecks because if Russia seized it, the Baltic states (Estonia, Latvia, Lithuania) would be physically cut off from the rest of the NATO alliance.

• Baltic Fleet HQ: Kaliningrad serves as the official headquarters of the Russian Baltic Sea Fleet.
• A2/AD Fortress: Russia has turned the territory into a heavily militarised forward bastion. It is packed with advanced S-400 anti-aircraft missile systems, anti-ship missiles, and electronic warfare units designed to deny NATO freedom of movement in Northern Europe.
• Nuclear Strike Capability: Russia permanently deploys nuclear-capable Iskander-M ballistic missiles in Kaliningrad. Because of its unique geography, these weapons can strike almost any major European capital within minutes, functioning as a massive geopolitical deterrent.

• German Origins: For centuries, the city was known as Königsberg and served as the historic capital of German East Prussia. It was famously the birthplace and home of the legendary philosopher Immanuel Kant.
• World War II Cession: The city was heavily destroyed during WWII. Following Nazi Germany's defeat in 1945, the territory was ceded to the Soviet Union under the Potsdam Agreement.
• Renaming: In 1946, the Soviets renamed the city and region Kaliningrad after the Bolshevik revolutionary Mikhail Kalinin. The German population was subsequently expelled and replaced with Soviet citizens.
• Post-Soviet Isolation: When the Soviet Union collapsed in 1991, neighbouring Soviet republics like Lithuania and Belarus became independent nations. As a result, Kaliningrad became physically detached from the newly formed Russian Federation.

• Stockpile Size: Experts estimate that India has produced enough weapons-grade plutonium for 140 to 225 warheads and has assembled up to 190 nuclear warheads. Out of these, more than 160 are allocated to operational delivery systems.
• Active Delivery Systems: India currently operates nine distinct nuclear-capable delivery platforms:
  • Air: Two categories of fighter aircraft (miraged across foreign-acquired platforms like the Mirage 2000, Jaguar, Sukhoi-30, and Rafale).
  • Land: Six types of land-based ballistic missiles, heavily anchored by the DRDO-developed Agni missile family (including the long-range Agni-V).
  • Sea: One operational sea-based system deployed via nuclear-powered ballistic missile submarines (SSBNs).
• Systems in the Pipeline: At least two more advanced delivery systems are nearing completion and expected to be fully deployed within the next few years.

• Founding: It was founded in September 1945 by Manhattan Project scientists at the University of Chicago immediately following the atomic bombings of Hiroshima and Nagasaki.
• Key Founders: Legendary physicists Albert Einstein and J. Robert Oppenheimer were among its early leaders and sponsors, driven by profound concern over the existential dangers of nuclear weaponry.
• Purpose: It operates as an independent, non-profit digital media and academic organization that alerts the public and policymakers about man-made threats to human survival.

• The Metaphor: Introduced by the BAS in 1947, the Doomsday Clock is a universally recognized symbol representing humanity's closeness to destroying the planet through dangerous technologies. Midnight represents global apocalypse.
• Current Setting: The clock is set at an unprecedented 85 seconds to midnight, the closest it has ever been to global catastrophe, driven by the war in Ukraine, nuclear modernization programs, and the collapse of arms control treaties.
• Governance: The clock's time is adjusted annually by the BAS Science and Security Board in consultation with its Board of Sponsors, which includes numerous Nobel Laureates.

• Nuclear Risk: Proliferation, modernization of nuclear arsenals, and the risk of accidental or intentional nuclear warfare.
• Climate Change: The acceleration of global warming, ecosystem collapse, and the political stagnation surrounding green energy transitions.
• Disruptive Technologies: The unregulated rise of technologies that could threaten humanity, including military Artificial Intelligence (AI), cyber warfare, and advanced biotechnology (like synthetic pathogens).
