Current Affairs Quiz – November 2025

Notes:
The Cochin University of Science and Technology (CUSAT) has received a national patent for a machine learning-based radar technology to extract accurate rainfall data. The system was developed at the Advanced Centre for Atmospheric Radar Research (ACARR). It uses a Hybrid Adaptive Bi-Gaussian Fitting Algorithm with a Gaussian Mixture Model (GMM) to separate rain and air turbulence echoes. The innovation helps radars clean their data in real time, improving rainfall and wind accuracy up to 5 km in the troposphere. It enhances flood forecasting and early warning systems for Kerala, a state prone to extreme monsoon events.

Notes:
World Immunization Day is observed every year on November 10 to raise awareness about the importance of vaccines in preventing diseases and saving lives. Vaccines act as a barrier against infections and are one of the most effective public health measures in history. The day was established by the World Health Organization (WHO) in 2012. It marks the launch of the Expanded Programme on Immunization (EPI) in 1974, which aimed to provide vaccines to people worldwide.

Notes:
In November 2025, the Global Peace Prayer Festival (GPPF) was inaugurated at Thimphu, Bhutan. The 16-day festival is a global initiative dedicated to world peace and healing of humanity amid global conflicts. It is the first-ever Global Peace Prayer Festival bringing together leaders from Mahayana, Theravada, and Vajrayana branches of Buddhism. A key ritual, Jabzhi, is performed to cleanse negative karma and dispel destructive forces. India gifted Sacred Relics of Lord Buddha from the National Museum, New Delhi, symbolizing goodwill. The festival strengthens India–Bhutan spiritual ties and promotes global harmony.

Notes:
The Guwahati Municipal Corporation (GMC) launched the “Sahajeevan” project to comply with the Supreme Court directives on stray dogs. The initiative focuses on relocating stray dogs from educational institutions, hospitals, and public places to designated shelters after vaccination. The project aims to promote human-animal coexistence while ensuring safe relocation and vaccination. GMC plans to create awareness in all wards before vaccination drives to prevent public resistance.

Notes:
Oman has been elected to the International Coordinating Council of UNESCO’s Man and the Biosphere (MAB) Programme for the 2025–2029 term. The election took place during the 43rd UNESCO General Conference in Samarkand, Uzbekistan. The Environment Authority of Oman represented the Sultanate at the session. This achievement aligns with Oman Vision 2040 and the United Nations Sustainable Development Goals (SDGs). The MAB Programme promotes scientific collaboration to conserve biodiversity, manage protected areas, and support climate research. It also empowers youth and researchers through grants and promotes sustainable environmental practices globally.

Notes:
A drying climate in East Africa caused Lake Turkana’s water levels to drop, triggering earthquakes and volcanic activity beneath it. Lake Turkana, formerly Lake Rudolf, is a vast, shallow lake in northern Kenya, extending slightly into Ethiopia. It lies along the Eastern Rift Valley, separated from Lake Logipi by volcanic formations called the Barriers.

Notes:
Kovalam beach in Chengalpattu district, Tamil Nadu, received the International Blue Flag certification for the fifth consecutive year in 2025-26. The certification is awarded by the Foundation for Environmental Education (FEE), Denmark, and promotes sustainable tourism and responsible coastal management. Blue Flag recognition is based on 33 criteria, including water quality, environmental education, safety, waste management, cleanliness, and eco-friendly infrastructure. Kovalam beach first received the certification on September 21, 2021, becoming Tamil Nadu’s first Blue Flag beach.

Notes:
The Indian Army’s Southern Command, headquartered in Pune, successfully conducted the Akhand Prahaar exercise in the desert sector of Rajasthan under the tri-services exercise Trishul. The exercise validated the full-spectrum combat readiness of the Konark Corps through integrated use of all arms and services. It included mechanised and infantry manoeuvres, Special Heliborne Operations, and fighter ground attack missions by the Indian Air Force (IAF). The exercise demonstrated strong Army–Air Force coordination and joint operational excellence. It tested next-generation indigenous technologies, including drones, unmanned systems, counter-drone systems, and electronic warfare grids.

Notes:
The WHO released the Global Antibiotic Resistance Surveillance Report 2025 (GLASS), highlighting that Antimicrobial Resistance (AMR) in India remains one of the highest globally. The report revealed that one in three bacterial infections in India in 2023 was resistant to common antibiotics, far above the global average of one in six. Experts observed that India’s surveillance data—mainly from tertiary hospitals—overestimates national resistance levels, as primary and secondary care settings are underrepresented. The WHO urged India to expand nationwide surveillance and strengthen antibiotic stewardship. The report acknowledged India’s initiatives, including the National Programme on AMR Containment and Kerala’s AMRITH, which reduced over-the-counter antibiotic sales and showed early declines in AMR.

Notes:
The Naval Science & Technological Laboratory (NSTL), Visakhapatnam, under Defence Research and Development Organisation (DRDO), has developed a new generation of Man-portable Autonomous Underwater Vehicles (MP-AUVs). MP-AUVs are designed for mine countermeasure missions with Side Scan Sonar and underwater cameras as primary payloads for real-time detection and classification of Mine-Like Objects (MLOs). Deep learning-based target recognition algorithms enable autonomous classification, reducing operator workload and mission time. The system includes robust underwater acoustic communication for inter-AUV data exchange and improved situational awareness.
