Current Affairs Quiz - May 2025

Notes:
The American Association of Petroleum Geologists and the United States Geological Survey (USGS) have recently launched formal hydrogen exploration initiatives. Hydrogen is seen as the fuel of the future due to its ability to help decarbonize the global economy and reduce greenhouse gas emissions. Natural hydrogen, or white hydrogen, is hydrogen that naturally occurs in the Earth’s crust, unlike industrially produced hydrogen. It forms through geological processes such as serpentinisation, where water reacts with iron-rich rocks, radiolysis, the breakdown of water by radioactive rocks, and the decomposition of organic matter in deep geological formations.

Notes:
A massive explosion recently hit Iran’s Shahid Rajaee Port in Bandar Abbas, causing a huge fire and leading to many deaths and injuries. The blast is suspected to have been caused by sodium perchlorate, a chemical used in ballistic missile propulsion. Shahid Rajaee Port is Iran’s largest and most advanced commercial port. It is located near the Strait of Hormuz, a vital route through which about 26% of the world’s oil is transported. The port manages 85% of Iran’s container cargo, 52% of its oil trade, and over half of its total maritime cargo. It lies along the International North-South Transport Corridor (INSTC), linking the Indian Ocean and Persian Gulf to the Caspian Sea, Russia, and Northern Europe.

Notes:
The Ministry of Social Justice and Empowerment (MoSJE) and the United Nations Development Programme (UNDP) are now working together under the wastepickers component of the National Action for Mechanised Sanitation Ecosystem (NAMASTE) Scheme. UNDP is providing financial support to State Project Management Units (PMUs) to strengthen the scheme’s implementation. The NAMASTE Scheme was jointly launched by Ministry of Social Justice and Empowerment (MoSJE) and the Ministry of Housing and Urban Affairs (MoHUA) in 2023 to protect the safety and dignity of sanitation workers. Its wastepicker component was launched in 2024 with the goal to digitally profile and register 2.5 lakh wastepickers across India. It also provides health insurance under Ayushman Bharat–Pradhan Mantri Jan Arogya Yojana (PMJAY), and offers skill development training.

Notes:
Tunnel No. 8 (T-8) is set to become India’s longest railway tunnel at 14.57 km, overtaking Tunnel No. 50 (T-50), which is 12.77 km long on the Udhampur-Srinagar-Baramulla Railway Link. It is part of the Rishikesh–Karnaprayag Broad Gauge Rail Link Project in Uttarakhand. T-8 is a twin tunnel located on the Devprayag–Janasu stretch of this 125-km rail line. The Rishikesh–Karnaprayag Broad Gauge Rail Link Project is being implemented by Rail Vikas Nigam Limited (RVNL), a Navratna Public Sector Undertaking under the Ministry of Railways.

Notes:
The Indo Tibetan Border Police (ITBP) recently scaled Mt. Makalu, the fifth highest mountain in the world. Mt. Makalu stands at 8,485 meters above sea level and is located in the Mahalangur range of the Nepal Himalayas on the Nepal-Tibet border. It lies 23 kilometers southeast of Mount Everest and is part of the Makalu Barun National Park. The mountain is famous for its pyramid-like shape with sharp ridges and includes two subsidiary peaks, Makalu I and Makalu II.

Notes:
A recent report by the Wildlife Justice Commission (WJC) says global trafficking of pangolin scales has dropped sharply since 2020 due to COVID-19 disruptions, strong law enforcement, and changing smuggling methods. Pangolins are insect-eating mammals found in tropical forests, grasslands, and farms, often near people. There are 8 species of pangolins — 4 in Africa and 4 in Asia, including the Indian pangolin found in India, Nepal, Sri Lanka, and Bangladesh. They eat ants and termites, helping control pests and improve soil, which supports healthy ecosystems. Pangolins are hunted for their meat and scales used in traditional medicine. The Indian pangolin is listed as Endangered and the Chinese pangolin as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

Notes:
Coal Miners Day 2025 is observed on May 4 to recognise the vital role of coal miners in powering industries and energy systems. It honours their hard work in dangerous conditions and reminds us of their rights, health, and safety needs. The day also highlights past mining disasters and the need for better support, especially during the shift to clean energy. The Mines Act, 1952 was passed to provide medical care, safety rules, and rescue services for miners. The Coal Mines Act, 1974 aimed to conserve co

Notes:
Scientists are closely watching the Axial Seamount as it is expected to erupt for the first time in ten years. Axial Seamount is an underwater shield volcano located about 300 miles off the coast of Oregon, United States, in the Pacific Ocean. It has a large caldera at its summit and rises to a depth of 1,400 meters below sea level. The volcano was formed by a hot spot, where molten material from Earth’s mantle rises into the crust. It lies on the Juan de Fuca Ridge, the tectonic boundary between the Pacific and Juan de Fuca plates. It features hydrothermal vents, which are underwater hot springs that release mineral-rich plumes heated by magma.

Notes:
Prime Minister Narendra Modi launched the seventh edition of the Khelo India Youth Games on May 4, 2025, through videoconferencing. The Khelo India Youth Games are being held in Bihar for the first time, from May 4 to 15, across five districts including Patna, Nalanda, Gaya, Bhagalpur, and Begusarai. More than 8,500 athletes and 1,500 technical staff are participating in 28 sports. Bihar has seen new institutions like the Khelo India State Centre of Excellence and Bihar Sports University set up.

Notes:
Iran recently unveiled a new solid-fuel ballistic missile named Ghassem Basir. It is a Medium-Range Ballistic Missile (MRBM) developed to strike targets over 1,200 kilometers away. The missile is about 11 meters long and weighs around 7 tons. It uses carbon fiber composite material for its body, making it lighter and harder to detect by radar. It runs on solid fuel, making it quicker to launch and easier to store than liquid-fuel missiles. It can reach speeds up to Mach 12. A thermal imaging sensor helps it track targets using heat in the final phase of flight. It has a Maneuverable Reentry Vehicle (MaRV) that detaches mid-flight to avoid radar and improve accuracy. It can be launched from mobile Transporter-Erector-Launchers (TELs), even from vehicles that look like civilian trucks.
