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:
Amazon has launched the first 27 satellites under its Project Kuiper to build an internet-from-space network. Project Kuiper is Amazon’s satellite broadband initiative using Low Earth Orbit (LEO), which is up to 2,000 kilometers above Earth. It includes around 3,232 satellites, ground stations, and customer terminals to provide the service. The goal is to deliver high-speed, low-latency, and affordable internet to remote and underserved regions globally. The project is named after the Kuiper Belt, a distant region of the solar system beyond the eight planets. It is Amazon’s answer to SpaceX’s Starlink satellite internet system.

Notes:
Finalists from 11 cities were selected through regional contests to compete in the WAM! (WAVES Anime & Manga Contest) national finale at WAVES 2025. The World Audio-Visual & Entertainment Summit (WAVES) 2025 is held from May 1 to 4, 2025, at the Jio World Convention Centre in Mumbai, India. WAVES (World Audio-Visual & Entertainment Summit) 2025 promotes India’s talent in Animation, Visual Effects, Gaming, Comics, and Extended Reality (AVGC-XR). The summit is themed “Create in India, Create for the World” to position India as a global creative powerhouse.

Notes:
Rajasthan has joined India’s first inter-state cheetah conservation corridor with Madhya Pradesh. This wildlife corridor is designed to connect protected areas in both states, allowing reintroduced cheetahs to roam safely across a vast ecosystem. The corridor covers 17,000 square kilometers, with 10,500 square kilometers in Madhya Pradesh and 6,500 square kilometers in Rajasthan. Key locations include Palpur Kuno National Park and Gandhi Sagar Sanctuary in Madhya Pradesh, which will serve as cheetah habitats. Mukundara Hills Tiger Reserve in Rajasthan, along with several districts like Kota and Sawai Madhopur, has been identified as a cheetah habitat.

Notes:
Vietnam hosts the United Nations (UN) Day of Vesak in 2025 from May 6 to 8 in Ho Chi Minh City. The United Nations Day of Vesak marks the birth, enlightenment, and passing away of Lord Buddha. In a historic first, the sacred Buddha Relic from Sarnath, India, will be sent to Vietnam for special exposition. The event is being organized by the Ministry of Culture, Government of India, along with the International Buddhist Confederation (IBC).

Notes:
The Gujarat High Court recently upheld a demolition drive carried out by state authorities in Ahmedabad’s Chandola Lake area. Chandola Lake, located in Ahmedabad, Gujarat, is an artificial lake established by Tajn Khan Nari Ali, the wife of a Mughal Sultan. Covering an area of approximately 1,200 hectares, the lake serves as a key water source for nearby industrial and residential areas. It has a circular shape and is divided into two parts, Chota Chandola and Bada Chandola. The Kharicut Canal Scheme, one of Gujarat’s oldest irrigation schemes, was introduced to irrigate 1,200 acres of rice land near the lake. The lake is home to various bird species, including cormorants, painted storks, and spoonbills.

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:
India has become the first country in the world to develop genome-edited rice varieties. The Indian Council of Agricultural Research (ICAR) has developed two such varieties named DRR Rice 100 (Kamla) and Pusa DST Rice. These rice varieties were developed using genome editing technology based on Clustered Regularly Interspaced Short Palindromic Repeats-CRISPR Associated Protein (CRISPR-Cas). This technology allows precise changes in the genetic material without adding any foreign DNA. Genome editing targeted the Site Directed Nuclease 1 (SDN1) and SDN2 types of genes, which are approved under India’s biosafety rules. The development was supported by the National Agricultural Science Fund (NASF), which funds strategic agricultural research.

Notes:
Scientists from the University of Oxford have suggested a new way to monitor volcanic eruptions using a method called shear-wave splitting. Shear-wave splitting happens when seismic waves travel at different speeds depending on their direction, especially through rocks with tiny cracks. This technique was studied at Mount Ontake in Japan, which is an active stratovolcano located on Honshū Island, near Tokyo. Mount Ontake is Japan’s second-highest volcano and lies in the Pacific Ring of Fire.

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.
