Current Affairs Quiz - May 2025

Notes:
A six-year-old girl in Kerala’s Malappuram district sadly died of rabies even after getting preventive vaccination, highlighting a serious public health concern. Rabies is a fatal zoonotic disease caused by the Rabies virus (RABV), which attacks the nervous system. Rabies virus is an RNA virus from the rhabdovirus family and spreads in two main ways in the body. It can directly enter the peripheral nervous system and reach the brain. Or it can first hide and multiply in muscle tissue, then move into the nervous system through neuromuscular junctions. Once in the brain, it causes severe and deadly inflammation.

Notes:
A rare inscription from the time of Vikramaditya I of the Badami Chalukya dynasty was recently found at Madapura Lake in Davangere district, Karnataka. Vikramaditya I ruled from 644 Common Era (CE) to 681 CE. He became king after the defeat of his father Pulakeshin II by the Pallava king Narasimhavarman I. His most important military success was the recapture of Vatapi, the Chalukya capital, from the Pallavas. He supported temple architecture and encouraged the construction of freestanding temples, a key feature of Chalukya style. The inscription offers new insights into his rule and regional history.

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:
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 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:
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:
Tissue-cultured teak is being promoted in India as a high-yield, fast-return solution to enhance timber cultivation and trade, sparking discussions on its economic and ecological impact. Teak (Tectona grandis) is renowned for its strength, durability, and resistance to pests and water, earning it the title “king of timbers.” It is a valuable tropical hardwood used in shipbuilding, furniture, and flooring. India holds 35% of the world’s planted teak forests, with Asia contributing over 95% of global teak resources. Madhya Pradesh and Maharashtra have the largest areas of native teak forests, according to the FAO Global Teak Resources and Market Assessment 2022. Teak is native to South and Southeast Asia and grows mainly in moist deciduous forests.

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.

Notes:
In a major step toward digital transformation, Chhattisgarh Chief Minister laid the foundation for India’s first Artificial Intelligence-based Data Center Park in Raipur. The facility will start with a five megawatt capacity and aims to grow to 150 megawatts. A 2.7-hectare area is being developed as a Special Economic Zone (SEZ) focused on Artificial Intelligence (AI) services. The project will see an investment of Rs 2,000 crore as it expands. The center will support green, energy-efficient technologies for sustainable operations. It will serve sectors like AI, Financial Technology (FinTech), Health Technology (HealthTech), defense, and data analytics. The infrastructure will use Graphics Processing Unit (GPU)-based systems for real-time data processing, streaming, and analytics.

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.
