Current Affairs Quiz - May 2025

Notes:
India recently signed agreements to supply 4.12 lakh tonnes of green hydrogen derivatives to Japan and Singapore. The Green Hydrogen Certification Scheme of India (GHCI) was launched simultaneously to ensure credible and transparent green hydrogen production. GHCI is India’s first certification framework to verify that hydrogen is produced exclusively using renewable energy. This certification ensures hydrogen is recognized as “green.” GHCI was launched by the Ministry of New and Renewable Energy (MNRE). The Bureau of Energy Efficiency (BEE) is the nodal agency for GHCI. It is supported by the National Green Hydrogen Mission.

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:
A recent study by the Global Antibiotic Research and Development Partnership (GARDP) showed that many multidrug-resistant infections in low- and middle-income countries, including India, are not being treated properly due to lack of access. GARDP is a not-for-profit organization that creates new antibiotic treatments for drug-resistant bacterial infections and ensures they reach people in need. It focuses on public health by developing antibiotics to fight the current antimicrobial resistance (AMR) crisis and protect future generations. GARDP was founded by the World Health Organization (WHO) and Drugs for Neglected Diseases initiative (DNDi) under the Global Action Plan on AMR in 2015.

Notes:
At the recent World Audio Visual Entertainment Summit (WAVES) in Mumbai, the Prime Minister highlighted India’s growing Orange Economy driven by content, creativity and culture. The Orange Economy, also called the creative economy, covers sectors that are based on cultural and creative ideas. As per the United Nations Economic Network, it focuses on using creative assets to boost economic growth and development. It combines economic, cultural and social factors while linking with technology, intellectual property and tourism. It includes industries based on individual talent, skill and innovation that can generate jobs, income and cultural value.

Notes:
Global defence spending is rising fast due to uncertainty and rapid technology growth. As per Stockholm International Peace Research Institute (SIPRI), military expenditure reached $2.718 trillion in 2024, a 9.4% rise from 2023. China has the largest active military force with 2,035,000 personnel in 2025, according to Global Firepower. India ranks second with about 1,455,550 active personnel, showing strong defence strength and rising South Asian influence. The United States of America stands third with 1,328,000 troops, slightly reduced due to more focus on tech-based defence. Russia and Ukraine boosted troop numbers since 2022 due to ongoing conflict between them.

Notes:
Reliance NU Suntech recently signed a 25-year Power Purchase Agreement with the Solar Energy Corporation of India Limited (SECI) to build Asia’s largest single-location integrated solar and Battery Energy Storage System (BESS) project. SECI is a Central Public Sector Undertaking (CPSU) under the Ministry of New and Renewable Energy (MNRE), dedicated to expanding Renewable Energy (RE) in India. SECI was formed in 2011 as a not-for-profit company and later became a commercial entity in 2015. It was established to support the National Solar Mission and has Miniratna Category-I status. SECI acts as the main agency for implementing solar, wind, and hybrid energy projects across India. It also helps fulfill India’s Nationally Determined Contributions (NDCs) by inviting developers through tenders for RE projects.

Notes:
A new non-contact wearable device developed by researchers from the United States and South Korea can monitor health by measuring skin flux without touching the skin. The device is about the size of a smartphone and tracks molecular movements like vapour leaving the body and chemicals entering through the skin. It was developed under the leadership of Professor John A. Rogers at Northwestern University, USA. It creates a small sealed microclimate next to the skin and uses wireless electronics and tiny sensors to detect water vapour, carbon dioxide (CO₂), and volatile organic compounds (VOCs). A remote-controlled valve adjusts the chamber’s openness for accurate comparisons.

Notes:
Recently, all political parties in Punjab united and firmly opposed releasing any extra water to Haryana from the Bhakra Dam, showing strong regional consensus. The Bhakra Dam is a concrete gravity dam built across the Sutlej River, located near the Punjab-Himachal Pradesh border. It stands near Bhakra village in Bilaspur district of Himachal Pradesh. It is the world’s highest straight gravity dam with a height of 207.26 meters. It is Asia’s second tallest dam after the 261-meter-high Tehri Dam in Uttarakhand. The dam is 518.25 meters long and about 9.1 meters wide at its crest.

Notes:
A research team from the Hong Kong University of Science and Technology (HKUST) has made the first-ever experimental observation of a two-dimensional layered altermagnet at room temperature. Altermagnets are a new class of antiferromagnetic materials that show momentum-dependent spin splitting without needing spin–orbit coupling (SOC) or overall magnetization. This spin splitting is caused by exchange interactions between magnetic sublattices connected by crystal symmetry, known as C-paired spin-valley locking (SVL). Altermagnets combine the stable spin properties of antiferromagnets with spin-split energy bands, making them promising for next-generation spintronic devices.

Notes:
India recently halted the flow of water through the Baglihar Dam on the Chenab River, a significant move impacting water access to Pakistan. The Baglihar Dam, also known as the Baglihar Hydroelectric Power Project, is located on the Chenab River in the Doda District of Jammu and Kashmir. It features a concrete gravity dam that is 144.5 meters high and 363 meters long, with a reservoir capacity of 475 million cubic meters. The underground powerhouse of the project measures 221 meters long, 24 meters wide, and 51 meters high.
