Science & Technology Current Affairs MCQs

Notes:
Tamil Nadu has requested the Union government to add the mumps vaccine to the Universal Immunization Programme (UIP). UIP provides free immunization against 12 diseases, including Diphtheria, Tetanus, Polio, Measles, Hepatitis B, and others. Mumps is a contagious viral infection affecting the salivary glands, usually mild and self-limiting. It primarily affects children and young adults, with symptoms like jaw swelling, fever, fatigue, appetite loss, and headaches. Mumps spreads through direct contact or airborne droplets from an infected person’s upper respiratory tract.

Notes:
A study by IBM highlights India’s growing interest in quantum computing, with active participation from students, developers, and institutions. Quantum computing uses quantum mechanics to solve complex problems beyond traditional computers’ capabilities. It leverages phenomena like superposition (qubits existing in 0, 1, or both states simultaneously) and entanglement (linked qubits affecting each other instantly). Quantum computers can handle tasks like cryptographic algorithms, simulations, and optimization far faster than classical systems. Unlike classical computers with binary bits, quantum computers use qubits, enabling exponentially faster computations for complex scenarios.

Notes:
BEML Ltd launched the BD475-2 Dozer, India’s largest and most advanced crawler dozer, showcasing the country’s engineering excellence and self-reliance. Powered by a 950 HP engine, it was developed entirely in-house at BEML’s Kolar Gold Fields facility. The BD475-2 Dozer enhances fuel efficiency and performance, supporting mining operations. This launch highlights India’s technological growth, aligning with the Aatma Nirbhar Bharat vision for sustainable development.

Notes:
Norovirus outbreaks in the United States (U.S.) have risen sharply, with 91 cases in early December, up from 69 in late November. Norovirus is a highly contagious virus causing gastroenteritis, also known as the “stomach flu” or “winter vomiting bug.” It affects people of all ages and spreads quickly through contaminated food, water, surfaces, or close contact. Noroviruses cause 90% of viral gastroenteritis outbreaks and nearly 50% of cases worldwide. People can get infected multiple times due to the variety of norovirus strains. Preventive measures focus on hygiene and proper food handling to limit its spread.

Notes:
The SSI Mantra surgical robot, recently approved by Central Drugs Standard Control Organisation (CDSCO), is India’s first indigenous robotic surgery system. Installed at Noble Hospitals in Pune, it features five robotic arms and advanced imaging technology. This innovative system enables minimally invasive surgeries, leading to faster recovery for patients. The SSI Mantra is part of a growing field of robotic surgery that enhances precision and control, making complex procedures more accessible. Its introduction marks a significant advancement in India’s healthcare technology landscape, promising better patient outcomes across various surgical disciplines.

Notes:
The Food Safety and Standards Authority of India clarified the use of methylcobalamin (MeCbl), an active form of Vitamin B12. Methylcobalamin, structurally distinct from other Vitamin B12 forms, contains a methyl group bonded to a cobalt atom. It is found in supplements and food sources like fish, meat, eggs, milk, and milk products. Vitamin B12 is essential for DNA synthesis, red blood cell production, and neurological function. Deficiency can cause severe health issues, often requiring supplementation. It supports vital functions like cell growth, blood formation, and protein synthesis.

Notes:
Researchers introduced Twigstats, a tool for time-stratified ancestry analysis, in a Nature study. Twigstats significantly enhances statistical power and reduces errors in ancestry studies. It provides high-resolution, precise individual-level ancestry analysis. The tool is coded in C++ and uses the statistical language R. Twigstats enables fine-grained analysis of specific historical periods.

Notes:
Swiss researchers have developed a gene editing technique to potentially treat Stargardt disease, also known as Stargardt macular degeneration. This rare genetic eye condition causes progressive vision loss in children and young adults, usually bilateral, involving both eyes. The disease is characterized by excessive lipofuscin buildup over the macula, responsible for clear central vision. The disease is more common in males and affects 1 in 8000 to 10,000 populations. Currently, there is no cure for the disease.

Notes:
India has joined the Eurodrone programme as an observer state. Eurodrone, a twin-turboprop UAV, is designed for Medium Altitude Long Endurance (MALE) missions. It has a payload capacity of 2.3 tonnes, endurance of up to 40 hours, and operates in diverse environments, including severe weather. Conceived in 2022, it passed its preliminary design review in 2024 and aims to enter service by 2030. The drone supports ISTAR, maritime surveillance, anti-submarine warfare, and airborne early warning missions. Eurodrone is Europe’s effort for collective defense, reducing reliance on US and Israeli platforms. The members are Germany, France, Italy, and Spain.

Notes:
The Finance Minister announced a ₹20,000 crore ‘Nuclear Energy Mission’ to develop indigenous Small Modular Reactors (SMRs). SMRs are small nuclear reactors with a maximum output of 300 MWe, producing 7.2 million kWh per day. In comparison, large nuclear plants generate over 1,000 MWe and 24 million kWh per day. SMRs are small, modular, and reactor-based, generating low-carbon electricity. They have small footprints, lower capital costs, and can be factory-built. SMRs can be deployed in locations unsuitable for large nuclear plants. They support incremental power additions, energy hubs, industrial heating, district heating, and hydrogen production.
