PM Modi Completes 25 Years as Head of Government

In the News: Prime Minister Narendra Modi completed 25 years as the head of government on October 7, 2026. His journey began when he became the Chief Minister of Gujarat on October 7, 2001. He later became the Prime Minister of India in 2014 and has continued in office after the 2019 and 2024 general elections.

Key Points:

• 25-Year Milestone: Narendra Modi completed 25 continuous years as a head of government. The period includes his tenure as Chief Minister of Gujarat and Prime Minister of India. The Union Cabinet passed a resolution congratulating him on the milestone.
• Gujarat Tenure: Modi first assumed office as Chief Minister of Gujarat on October 7, 2001. He continued in that post until May 2014. His Gujarat tenure is often associated with governance reforms, infrastructure expansion and industrial development.
• Prime Ministerial Tenure: Modi became Prime Minister of India in May 2014. He returned to office after the 2019 Lok Sabha elections and again after the 2024 general elections. His tenure has seen major policy initiatives in welfare delivery, digital governance and infrastructure.
• Democratic Significance: The milestone is significant because it reflects uninterrupted elected leadership at the state and national levels. It also highlights the role of electoral mandates in India’s parliamentary democracy. The Cabinet resolution described the tenure as a sign of democratic continuity.
• Governance Themes: The milestone has been linked with programmes on development, welfare delivery, digital public infrastructure and national infrastructure expansion. It also marks a long phase of centralised political leadership in Indian public life.

Plague Risk Emerges in Russia

In the News: International concern arose after a laboratory worker at a plague research institute in Irkutsk, Siberia died from pneumonia of undetermined origin. Russian authorities informed the World Health Organization that no confirmed plague cases had been recorded in Irkutsk. The WHO sought further details to assess the public health risk more clearly.

Key Points:

• Russia Health Alert: The case involved a worker linked with a Siberian plague research institute. Her death from unexplained pneumonia led to concerns over a possible pneumonic plague link. Russian authorities have said that no plague outbreak has been confirmed.
• WHO Response: The World Health Organization sought more information from Russia on laboratory tests, contact tracing and possible causes of death. WHO officials said that more details were needed for a fuller risk assessment. The case underlined the importance of transparent disease reporting.
• Quarantine and Testing: Around 200 contacts were initially placed under observation as a precautionary measure. Russian health authorities reported that tests on contacts did not detect dangerous infectious pathogens.
• About Pneumonic Plague: Pneumonic plague is a serious bacterial infection caused by Yersinia pestis. It affects the lungs and can spread through respiratory droplets if untreated. Early diagnosis and antibiotics are important for controlling the disease.
• Public Health Relevance: The incident shows the importance of pathogen safety, laboratory biosecurity and global health surveillance. It also reflects why countries are expected to share timely information under international health rules.

Indian Mathematician Mahesh Kakde Wins 2026 Ramanujan Prize for Number Theory

In the News: Indian mathematician Mahesh Kakde was awarded the 2026 Ramanujan Prize for young mathematicians from developing countries. The prize recognised his major contributions to algebraic number theory. Kakde is a professor at the Indian Institute of Science, Bengaluru.

Key Points:

• Award Winner: Mahesh Kakde won the 2026 Ramanujan Prize for his contributions to algebraic number theory. He is associated with the Department of Mathematics at the Indian Institute of Science, Bengaluru. The award adds to India’s recognition in global mathematical research.
• Research Area: Kakde’s work focuses on algebraic number theory, especially structures used to solve problems related to integers and their generalisations. His research includes important results in noncommutative Iwasawa theory. It also relates to the Gross-Stark and Brumer-Stark conjectures.
• About the Prize: The Ramanujan Prize is awarded to young mathematicians from developing countries. It is administered jointly by the International Centre for Theoretical Physics and the International Mathematical Union. The prize has been awarded annually since 2005.
• Eligibility and Purpose: The prize is generally given to researchers below 45 years of age from developing countries. It recognises outstanding research in mathematical sciences. It is named after Indian mathematician Srinivasa Ramanujan.

Nobel Prize in Chemistry 2026 Awarded to Henri B. Kagan and Kenso Soai

In the News: The 2026 Nobel Prize in Chemistry was awarded to Henri B. Kagan and Kenso Soai. They were recognised for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis. Their work helped explain how molecular handedness can be amplified in chemical reactions.

Key Points:

• 2026 Chemistry Nobel: Henri B. Kagan of France and Kenso Soai of Japan received the Nobel Prize in Chemistry 2026. The Royal Swedish Academy of Sciences recognised their discoveries in asymmetric organic synthesis. The prize was shared equally between the two scientists.
• Core Discovery: Their work deals with non-linear effects and autocatalysis in chemical reactions. Autocatalysis means a reaction in which the product itself helps speed up the formation of more product. This helped chemists understand how one molecular form can become dominant.
• Molecular Chirality: The prize is linked with the concept of chirality, where molecules exist as mirror-image forms. Such mirror-image molecules can behave differently in biological systems. This is especially important in medicine and pharmaceutical chemistry.
• Soai Reaction: Kenso Soai is known for the Soai reaction, a major example of asymmetric autocatalysis. The reaction showed how tiny initial imbalances in molecular handedness can be amplified. This helped address a long-standing question about homochirality in nature.

Indian Air Force Day 2026

In the News: Indian Air Force Day 2026 is being observed on October 8 to mark the 94th anniversary of the Indian Air Force. The Indian Air Force was established on October 8, 1932. The theme for the 2026 celebration is “Indian Air Force – Infallible, Impervious and Precise.”

Key Points:

• 94th Anniversary: Indian Air Force Day 2026 marks the 94th anniversary of the force. The day commemorates the establishment of the Indian Air Force on October 8, 1932. It honours the contribution of air warriors to national security.
• 2026 Theme: The theme for the 2026 celebration is  Indian Air Force – Infallible, Impervious and Precise. It reflects operational readiness, resilience and precision. The theme also highlights the changing role of air power in modern warfare.
• IAF Motto: The motto of the Indian Air Force is “Nabha Sparsham Deeptam,” meaning “Touch the Sky with Glory.” It is taken from the Bhagavad Gita. The motto reflects courage, discipline and excellence in air operations.
• Role of the IAF: The Indian Air Force protects Indian airspace and supports military operations during conflict. It also plays a major role in humanitarian assistance, disaster relief, evacuation and emergency response. Its transport and helicopter fleets are important during natural disasters.
• Modernisation Focus: The IAF is working on modernisation through advanced aircraft, air defence systems, drones, network-centric warfare and indigenous platforms. The day also showcases ceremonial parades, air displays and public outreach activities.
