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 Prime Minister of India will officially inaugurate the Vizhinjam International Seaport in Kerala, marking a major milestone in global maritime connectivity for the state. Vizhinjam Port is located in Vizhinjam, a coastal town in Thiruvananthapuram district of Kerala. It is India’s first dedicated transshipment port and also the country’s first semi-automated port. The port is built at a cost of about ₹8,900 crore under the Public-Private Partnership (PPP) model and is operated by the Adani Group, while the Kerala government holds the majority stake. It has the deepest breakwater in India, nearly three kilometres long, with a natural draft of about 20 metres. The port features India’s first home-built, Artificial Intelligence (AI)-powered Vessel Traffic Management System, developed with Indian Institute of Technology (IIT) Madras.

Notes:
Archaeological Survey of India (ASI) recently found 11 Satavahana-era inscriptions in the Gundaram Forest of Telangana’s Peddapalli district. Two inscriptions mention the Chutu dynasty and a Satavahana prince named Kumāra Hakusiri. These inscriptions are written in early Brahmi script and show religious and political symbols. The Satavahana dynasty was founded by Simuka after the Mauryan Empire, around mid-1st century BCE. The word “Satavahana” in Prakrit means “driven by seven,” symbolizing the chariot of the Sun God. Their main regions were Andhra Pradesh, Telangana, and Maharashtra. They ruled from capitals like Pratishthana (Paithan) and Amaravati.

Notes:
The United States has recently approved a military hardware and logistics support package for India to assist in the Integrated Platform for Maritime Domain Awareness (IPMDA). IPMDA is a technology and training initiative designed to boost maritime domain awareness in the Indo-Pacific region and increase transparency in its vital waterways. It was announced by the Quadrilateral Security Dialogue (QUAD), which includes India, Australia, Japan, and the United States, during the Tokyo summit in 2022. The initiative uses innovative technology to provide near real-time information on maritime activities to partners in Southeast Asia, the Indian Ocean region, and the Pacific.

Notes:
The Army and Air Force versions of the Advanced Light Helicopter (ALH) Dhruv have been cleared for flying again after a review by a Defect Investigation Committee. All 330 ALH helicopters were grounded after an ALH Mark-III of the Indian Coast Guard crashed during a training sortie in Porbandar, Gujarat in January 2025, killing three crew members. The helicopter was also absent from the Aero India 2025 event due to safety concerns. ALH Dhruv is a multi-role helicopter developed by Hindustan Aeronautics Limited (HAL) for transport, utility, reconnaissance, and medical evacuation.

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:
A recent breakthrough came as an international team of scientists successfully mapped the genome of the Saola using tissue fragments from hunter-collected remains. The Saola, scientifically named Pseudoryx nghetinhensis, is one of the rarest land mammals and is nicknamed the “Asian Unicorn” because of its secretive nature. It was first discovered in 1992 during a joint survey by the Vietnamese Ministry of Forestry and the World Wide Fund for Nature (WWF). It is listed as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List, with only about 50 to 300 individuals estimated as of 2015. The Saola lives in the evergreen forests of the Annamite Mountains along the Vietnam–Laos border, a region rich in biodiversity and rainfall.

Notes:
Public trespassing in the ecologically sensitive Bhimgad Wildlife Sanctuary (BWS) in Khanapur taluk has raised major concerns among conservationists recently. Bhimgad Wildlife Sanctuary is located in the Western Ghats in the Belgaum district of Karnataka. It was declared a wildlife sanctuary in December 2011 to protect its rich biodiversity. The sanctuary is named after the historic Bhimgad Fort, built by Shivaji Maharaj in the 17th century to defend against Portuguese forces. It borders Dandeli Wildlife Sanctuary, Bhagwan Mahaveer Sanctuary, Mollem National Park, Netravali Wildlife Sanctuary, and Mhadei Wildlife Sanctuary.

Notes:
Kozhikode city has recently been honoured with membership in the Global Network for Age-friendly Cities and Communities (GNAFCC) of the World Health Organization (WHO). GNAFCC was established in 2010 to help cities become better places for older people to live in. It has over 1300 members from 51 countries, promoting global cooperation on age-friendly policies. The aim is to connect cities, communities, and organizations to create supportive environments for ageing populations. It works to inspire change, share knowledge, and help cities find smart, practical solutions. This membership shows Kozhikode’s commitment to healthy ageing and inclusive urban development.

Notes:
Nauradehi Wildlife Sanctuary in Madhya Pradesh has recently been renamed as Veerangana Rani Durgavati Tiger Reserve. It will become the third home of cheetahs in India under the cheetah reintroduction project. This follows the earlier relocation of eight cheetahs from Namibia to Kuno National Park in September 2022. Later, twelve more cheetahs were brought from South Africa, making Kuno the first cheetah home in India. The move to expand the habitat aims to support cheetah conservation and reduce pressure on existing reserves. This development highlights India’s growing efforts in wildlife restoration and biodiversity protection.
