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:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Notes:
A rare inscription from the time of Vikramaditya I of the Badami Chalukya dynasty was recently found at Madapura Lake in Davangere district, Karnataka. Vikramaditya I ruled from 644 Common Era (CE) to 681 CE. He became king after the defeat of his father Pulakeshin II by the Pallava king Narasimhavarman I. His most important military success was the recapture of Vatapi, the Chalukya capital, from the Pallavas. He supported temple architecture and encouraged the construction of freestanding temples, a key feature of Chalukya style. The inscription offers new insights into his rule and regional history.

Notes:
Satwiksairaj Rankireddy and Chirag Shetty recently received the Major Dhyan Chand Khel Ratna Award for their outstanding achievements in badminton. The pair reached the No. 1 rank in the Badminton World Federation rankings in 2023 and won the Asian Games gold medal in Hangzhou. The Major Dhyan Chand Khel Ratna Award was originally established as the Rajiv Gandhi Khel Ratna in 1991–92 and renamed in 2021. It is India’s highest sporting honour, given for the most exceptional performance by a sportsperson over the last four years. Only performances in recognized international events are eligible for consideration. The award includes a ₹25 lakh cash prize, a medal, and a certificate of honour, with typically one award given each year.

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:
The President of India recently launched the Mediation Association of India and addressed the First National Mediation Conference 2025 in New Delhi. This event highlights the importance of the Mediation Act, 2023, which aims to revive India’s civilisational legacy of resolving disputes peacefully. The Act promotes out-of-court settlements and builds a structured system for mediation across the country. It encourages extending mediation to rural areas by legally empowering Panchayats to resolve village conflicts. This step supports social harmony, which is key to national strength and unity. Mediation reduces court burdens, speeds up justice, and strengthens the judicial system. It also boosts the ease of doing business and ease of living, helping in the journey towards Viksit Bharat by 2047.

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:
In a major step toward digital transformation, Chhattisgarh Chief Minister laid the foundation for India’s first Artificial Intelligence-based Data Center Park in Raipur. The facility will start with a five megawatt capacity and aims to grow to 150 megawatts. A 2.7-hectare area is being developed as a Special Economic Zone (SEZ) focused on Artificial Intelligence (AI) services. The project will see an investment of Rs 2,000 crore as it expands. The center will support green, energy-efficient technologies for sustainable operations. It will serve sectors like AI, Financial Technology (FinTech), Health Technology (HealthTech), defense, and data analytics. The infrastructure will use Graphics Processing Unit (GPU)-based systems for real-time data processing, streaming, and analytics.

Notes:
Australian Prime Minister Anthony Albanese has been re-elected, becoming the first leader in decades to win a second term, marking a major political milestone. With around 70.8% of votes counted, the Australian Broadcasting Corporation (ABC) reports that the Labor Party is set to win 85 seats, well above the 76 needed for a majority. The Opposition Liberal National Coalition is likely to secure 36 seats, while Independents are expected to get 10. After his win, Albanese called being Prime Minister the greatest honour of his life while addressing supporters in Sydney.

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.
