Current Affairs Quiz - May 2025

Notes:
The Central Bureau of Investigation (CBI) recently conducted multiple raids under Operation Hawk to crack down on cybercrime involving Online Child Sexual Exploitation (OCSE) with global links. The action followed inputs from United States (US) authorities and led to the arrest of two individuals from Mangalore and Delhi.The CBI’s International Operations Division registered cases under the Indian Penal Code (IPC), Information Technology (IT) Act, 2000, and Protection of Children from Sexual Offences (POCSO) Act, 2012.This comes as part of CBI’s broader efforts under earlier operations like Operation CARBON (2021) and Operation Megh Chakra (2022)

Notes:
Jal Shakti Minister C R Paatil held a review meeting on 30 April with the Wildlife Institute of India to assess the progress of the ‘Jalaj’ project. The ‘Jalaj’ project is a key initiative developed by the Ministry of Jal Shakti to support the rejuvenation of the Ganga River and biodiversity conservation. It involves setting up floating platforms on the Ganga River to promote livelihood activities for local communities. These platforms also raise awareness about conserving the river and its ecosystem. The project blends ecological restoration with sustainable development for Ganga-dependent populations.

Notes:
A new project called SeaCURE has begun on the south coast of England to remove carbon dioxide from the sea. The SeaCURE project is an initiative of the United Kingdom (UK) government. The SeaCURE project is testing if taking carbon directly from seawater can be a low-cost and large-scale way to cut down carbon dioxide in the air. This method is different from usual carbon capture techniques that focus on emissions at their source or pull carbon dioxide from the air. SeaCURE targets the ocean, where carbon levels are up to 150 times higher than in the atmosphere.

Notes:
The Subaru Telescope in Hawaii recently used the Hyper Suprime-Cam to carry out a deep sky survey from the University of Tokyo. It reported a Sigma Eight (S8) value of 0.747, which matches earlier results from gravitational lensing studies. Sigma Eight (S8) is a key measure in cosmology that shows how matter is clustered or “clumpy” across the universe on a scale of 26 million light-years. It tells scientists how much visible and dark matter is gathered in different parts of space. This finding helps us understand how the universe evolved from a smooth early state after the Big Bang.

Notes:
Maharashtra has topped the CareEdge State Ranking Report 2025, released by CARE Ratings Ltd (CareEdge Ratings). This is the second edition of the CareEdge State Rankings. The rankings evaluate state performance across seven key pillars: economic performance, fiscal management, infrastructure development, financial sector growth, social development, governance quality, and environmental sustainability. The evaluation uses 50 measurable indicators. The primary aim is to provide a data-driven assessment of state performance. The rankings help identify strengths, gaps, and opportunities for policy improvement. This report offers valuable insights for improving state governance and development strategies.

Notes:
Bodofa Upendranath Brahma was a respected leader of the Bodo community who championed non-violent struggle for tribal identity, rights and cultural preservation. On May 1, 2025, the Government of India (GoI) unveiled his 9-feet-high statue in New Delhi, marking his 35th death anniversary. Union Home Minister (UHM) Amit Shah presided over the unveiling and announced the naming of a major road and rotary after him. This tribute underscores the Government of India’s commitment to tribal empowerment and peacebuilding in India’s North East.

Notes:
Researchers at the Indian Institute of Space Science and Technology (IIST) have developed a 3D computational model to study thermoregulation in space. It shows that microgravity consistently increases human core body temperature, which is important for long-duration space missions. Microgravity is a condition of near-weightlessness experienced when objects are in free fall around Earth, not the absence of gravity. In microgravity, normal body functions like heat regulation are altered due to changes in blood flow and metabolism. The IIST model includes sweating, shivering, clothing, and organ heat to simulate real human conditions in space.

Notes:
Defence Research and Development Organisation (DRDO) has successfully conducted the first flight trial of the Stratospheric Airship Platform in Sheopur, Madhya Pradesh. The platform was developed by DRDO’s Aerial Delivery Research and Development Establishment (ADRDE) based in Agra. The airship carried an instrumental payload and reached a high altitude of about 17 kilometres. The total flight lasted 62 minutes and helped gather important data through onboard sensors. This data will help in building accurate simulation models for future high-altitude missions. The test also checked the envelope pressure control and emergency deflation systems, and the airship was safely recovered.

Notes:
Archaeologists have recently discovered prehistoric tools from the Lower Paleolithic age at Mangar Bani, highlighting its ancient human presence. Mangar Bani is a sacred grove and Paleolithic site located in the Aravalli hills on the Delhi-Haryana border. It lies within the only primary forest in the Delhi National Capital Region (NCR), meaning the forest is largely untouched by human activities and contains native tree species. Evidence shows continuous human occupation from around 100,000 years before present (BP) to 1000 AD. The site also has rock shelters and ancient rock and cave paintings estimated to be 20,000 to 40,000 years old.

Notes:
The Department of Biotechnology (DBT) has recently released detailed data, infographics, and graphical summaries on over 100 bacterial genomes under the ‘One Day One Genome’ initiative. A genome is the complete genetic material of an organism, made of unique DNA (Deoxyribonucleic Acid) or RNA (Ribonucleic Acid) sequences. These sequences are made of chemical units called nucleotide bases, and identifying their order is known as genomic sequencing. The ‘One Day One Genome’ initiative was launched in November 2024 by Department of Biotechnology (DBT) and Biotechnology Research and Innovation Council (BRIC). It is coordinated by BRIC-National Institute of Biomedical Genomics (NIBMG), West Bengal. Data contributions come from 13 BRIC institutions and two bodies: International Centre for Genetic Engineering and Biotechnology (ICGEB), New Delhi, and Regional Centre for Biotechnology (RCB), Faridabad.
