Current Affairs Quiz - May 2025

Notes:
The National Archives of India (NAI) has added the private papers of former President Dr. A.P.J. Abdul Kalam to its rich collection, making a major contribution to India’s historical records. It works under the Ministry of Culture and stores old government records that are no longer active but important for research and administration. It is the largest archival repository in South Asia and protects records of lasting value to the Government of India. NAI was started as the Imperial Record Department on 11 March 1891 in Kolkata and moved to New Delhi in 1911. The full transfer of records to Delhi was completed in 1937. NAI also enforces the Public Records Act, 1993 and Public Record Rules, 1997. It preserves over 34 crore pages, including official files, maps, censuses, treaties, debates, rare manuscripts, and government documents.

Notes:
United Kingdom (UK)-based health charity Encephalitis International has launched a global campaign titled ‘Preventing Future Encephalitis: Climate Change and Infectious Disease’ to raise awareness about encephalitis and promote vaccination. Encephalitis is the inflammation of active brain tissues caused by infections or autoimmune responses, affecting over 1.5 million people globally every year. The campaign highlights how climate change increases encephalitis risk by creating conditions for disease-carrying vectors like mosquitoes and ticks to spread. India is among high-burden countries, with 1,548 cases of Japanese encephalitis reported in 2024 from 24 states and union territories.

Notes:
The government has revamped the National Security Advisory Board (NSAB) after the Pahalgam terror attack, appointing former intelligence chief Alok Joshi as chairman. National Security Advisory Board (NSAB) is an advisory body under the National Security Council (NSC) structure. It is chaired by the Prime Minister, supported by the National Security Advisor (NSA) and the National Security Council Secretariat (NSCS). Established in 1998 after the Pokhran-II nuclear tests, it institutionalized India’s national security framework. The NSAB provides non-partisan strategic inputs on national security issues but is not a decision-making body. It reports to the NSCS and includes experts from various sectors.

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 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:
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:
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:
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:
India’s SVAMITVA scheme will be highlighted at the World Bank Land Conference in Washington, D.C., showcasing its role in digitalising rural land records. SVAMITVA stands for Survey of Villages and Mapping with Improvised Technology in Village Areas and was launched in 2020 as a central sector scheme. It aims to give rural residents legal documents for their residential properties to help them access loans and other financial services. Drone technology is used to survey land parcels in rural inhabited areas across India in phases. The scheme helps bring financial stability to rural citizens by treating property as a financial asset. It also ensures accurate land records for better rural planning and governance. The Ministry of Panchayati Raj (MoPR) is the nodal ministry for implementing the scheme. State Revenue or Land Records Departments implement the scheme with support from State Panchayati Raj Departments.

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.
