Current Affairs Quiz - May 2025

Notes:
The Maharashtra government has launched the Tourism Security Force, also known as Paryatan Mitra, to improve tourist safety and boost tourism. The pilot launch will be held during the Mahabaleshwar festival from 1st to 4th May 2025 in Satara district. The Tourism Department will appoint tourism police on a contract basis to make tourists feel secure while visiting the state. The Maharashtra Tourism Development Corporation will fund the project with help from the Maharashtra State Security Corporation and Satara police. These tourism police will also guide tourists by sharing information on cultural sites, laws, and sustainable tourism.

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 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:
Mizoram’s Animal Husbandry and Veterinary Department has reported over 3,050 pig deaths since March 2025 due to an outbreak of African Swine Fever (ASF) in the districts of Siaha, Lawngtlai, Lunglei, and Mamit. African Swine Fever (ASF) is a highly contagious viral disease that affects domestic and wild pigs with a mortality rate that can reach 100%. Though ASF does not affect humans, it severely impacts pig populations and causes major economic loss to farmers. The virus originated in Africa and has now spread globally.

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:
Tunnel No. 8 (T-8) is set to become India’s longest railway tunnel at 14.57 km, overtaking Tunnel No. 50 (T-50), which is 12.77 km long on the Udhampur-Srinagar-Baramulla Railway Link. It is part of the Rishikesh–Karnaprayag Broad Gauge Rail Link Project in Uttarakhand. T-8 is a twin tunnel located on the Devprayag–Janasu stretch of this 125-km rail line. The Rishikesh–Karnaprayag Broad Gauge Rail Link Project is being implemented by Rail Vikas Nigam Limited (RVNL), a Navratna Public Sector Undertaking under the Ministry of Railways.

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:
Indian Naval Ship (INS) Sharda arrived at Maafilaafushi Atoll in the Maldives for a Humanitarian Assistance and Disaster Relief (HADR) exercise from May 4 to 10, 2025. The exercise is being held in partnership with the Maldives National Defence Force (MNDF). It aims to improve coordination in disaster response, search and rescue, medical aid, and joint drills. This initiative strengthens the India-Maldives defence partnership. It aligns with India’s MAHASAGAR vision, which stands for Mutual and Holistic Advancement for Security and Growth across Regions. The exercise includes training and outreach to enhance regional preparedness.

Notes:
The Centre for Earth Sciences and Himalayan Studies (CESHS) has recently drilled Northeast India’s first geothermal production well at Dirang in West Kameng district, Arunachal Pradesh. This marks a major step towards using clean and renewable energy sources in the Himalayan region. Geothermal energy is the heat from within the Earth, used to produce electricity or direct heating. CESHS achieved this breakthrough after two years of detailed geochemical and structural surveys in hot spring sites of western Arunachal Pradesh. CESHS geosciences division head Rupankar Rajkhowa confirmed the success of the drilling project. This initiative can reduce dependency on fossil fuels and support green development in remote regions.

Notes:
Scientists recently found signs of ancient wildfires, called palaeofires, from the Permian Period about 250 million years ago in the Godavari Basin. Palaeofires are wildfire events recorded in ancient rocks, helping us understand Earth’s past vegetation, climate changes, and coal formation. The study covered a long geological timescale, from the Late Silurian to the present Quaternary Period. Researchers used methods like Palynofacies analysis, Raman Spectroscopy, Rock-Eval Pyrolysis, and Fourier Transform Infrared (FTIR) Spectroscopy to study tiny fossils and charcoal. They clearly identified charcoal formed on-site (in situ) and transported charcoal (ex situ), solving a major geological debate. They also found that sea-level changes affected how fire residues were preserved—more intact during sea-level drops (regressive) and more scattered during sea-level rise (transgressive).
