Current Affairs Quiz - May 2025

Notes:
Less than 1% of doctors in India have registered with the National Medical Register (NMR) eight months after its launch. National Medical Register (NMR) is a centralized digital database that includes all licensed allopathic (MBBS) doctors in India. It was launched in August 2024 under Section 31 of the National Medical Commission (NMC) Act, 2019. The Ministry of Health and Family Welfare, Government of India, is the nodal ministry for the NMR. The NMR aims to create a comprehensive registry of all allopathic doctors in India, ensuring transparency and accountability in the medical field. It also enhances public trust, helps in credential verification, and aids in policy planning for healthcare.

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:
The European Red Admiral butterfly, scientifically called Vanessa atalanta, has been recorded for the first time in India near Dharamshala, Himachal Pradesh. This rare sighting was confirmed during a butterfly survey at Thatharna Hill in the Dhauladhar mountain range, at an altitude of 2,500 metres. The observation was verified by Himalayan butterfly expert Lovish Garlani from the Himachal Pradesh Forest Department. This raises the total number of butterfly species in Himachal Pradesh to 440, highlighting the region’s rich biodiversity. The species is known for long migrations across Europe and North America and was last seen in South Asia in 2022 in Pakistan after a 93-year gap. It has no confirmed records from China, Mongolia, or Afghanistan, making its presence in India a significant eastward range expansion.

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:
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 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:
The Indian Council of Agricultural Research (ICAR) has recently developed two genome-edited rice varieties, marking a major advancement in Indian agricultural science. ICAR is an autonomous body under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture and Farmers Welfare, Government of India. It was founded on 16 July 1929, initially as the Imperial Council of Agricultural Research, following recommendations from the Royal Commission on Agriculture. ICAR’s headquarters is in New Delhi, and it coordinates research in agriculture, horticulture, fisheries, and animal sciences across India.

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:
Recently, scientists observed repeated unrest at Campi Flegrei between 1982–1984 and 2011–2024, involving land uplift, earthquakes, and underground rumbling due to rising fluid pressure. Campi Flegrei, also called the Phlegraean Fields, is an active volcanic system located near Naples, Italy. Unlike single-cone volcanoes like Mount Vesuvius, Campi Flegrei is a large caldera, which is a sunken volcanic area formed after a huge eruption. The caldera spans about 12 to 15 kilometers and was formed by a massive eruption nearly 39,000 years ago. That eruption may have triggered climate changes that contributed to the decline of Neanderthals.
