Science & Technology Current Affairs MCQs

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:
Turkey successfully tested the UAV-122 supersonic missile fired from the Bayraktar Akinci drone. Bayraktar Akinci is a long-endurance unmanned combat aerial vehicle (UCAV) developed by Turkish manufacturer Baykar. It supports fighter jets with air-to-ground and air-to-air attack capabilities. The drone measures 12.2 m in length, 4.1 m in height, and has a 20 m wingspan. It offers a 25-hour flight time and 7,500 km range. Equipped with AI-powered avionics, dual satellite communication, advanced radars, and collision avoidance systems, it enhances real-time situational awareness. It carries laser-guided munitions, missiles, and long-range weapons and is the first drone capable of launching air-launched cruise missiles.

Notes:
Union Minister Dr. Jitendra Singh announced the indigenously developed “Paracetamol” by Council of Scientific and Industrial Research (CSIR) during the 40th Foundation Day of the Department of Scientific and Industrial Research. CSIR’s new technology aims to produce paracetamol domestically, reducing dependence on imported raw materials. Karnataka-based Satya Deeptha Pharmaceuticals Ltd will manufacture affordable paracetamol using this breakthrough. The initiative supports India’s self-reliance in pharmaceutical production and aligns with PM Modi’s “Atmanirbhar Bharat” vision. The development addresses the current import dependency for key raw materials used in paracetamol production.

Notes:
Researchers discovered two rare Neuroptera species, Indophanes barbara and Glenochrysa zeylanica, in Kerala. Indophanes barbara, an antlion from the Myrmeleontidae family, does not build pits like other antlion larvae and lives in loose soil for protection. Adult Indophanes barbara resemble damselflies but can be identified by their long antennae and belong to holometabolous Neuroptera insects, unlike hemimetabolous damselflies. Glenochrysa zeylanica, a green lacewing from the Chrysopidae family, was rediscovered in Wayanad after 111 years and reported for the first time in India. Neuroptera, commonly called lacewings, are terrestrial insects with complex wing vein patterns.

Notes:
India launched the Indian Biological Data Centre (IBDC) Portals, making 10,000 whole genome samples accessible globally. The data set enables advancements in genomics, personalized healthcare, and medicine. IBDC supports seamless access to genetic data, aiding researchers in studying genetic variations and developing precise genomic tools. The Framework for Exchange of Data Protocols (FeED) ensures ethical and secure genomic data sharing under Biotech-PRIDE Guidelines. The GenomeIndia project, led by Department of Biotechnology (DBT), creates a comprehensive genetic diversity database for cutting-edge research. India plans to sequence 10 million genomes, enhancing innovation in healthcare, agriculture, and biotechnology.

Notes:
More than 30 dermatologists suggest renaming the fungus Trichophyton indotineae as its origin in India is unconfirmed despite reports from over 40 countries. Trichophyton indotineae is a fungal pathogen causing severe, treatment-resistant skin infections. It was named after India in 2020 based on isolates from India and Nepal. The fungus belongs to the dermatophyte group, causing dermatophytosis, which affects the skin, hair, and nails. It causes itchy, inflammatory infections on the groin, gluteal region, trunk, and face, affecting all ages and genders. It spreads via direct skin contact or contaminated objects and is resistant to terbinafine.

Notes:
China launched the world’s largest Compressed Air Energy Storage (CAES) project, “Nengchu-1”. It has begun full operation in Yingcheng, Hubei Province, China. It marks a milestone in China’s energy storage technologies and is the largest CAES facility globally. CAES stores electrical energy as potential energy by compressing air into sealed spaces like underground mines or salt rock caverns. Energy is stored during off-peak hours and released to the grid during peak demand.

Notes:
Russia’s atomic agency has shipped the reactor vessel for the sixth unit of Kudankulam Nuclear Power Plant to India. The Kudankulam plant, located in Tamil Nadu, is India’s largest nuclear power plant with six reactors and a total capacity of 6,000 MW. The reactor vessel, weighing 320 tonnes, was manufactured by Rosatom’s division Atommash and shipped from Novorossiysk at the end of 2024. The reactor vessel will travel 6,000 miles by sea to reach the construction site.

Notes:
Hindustan Aeronautics Limited (HAL) conducted the engine ground run of the Combat Air Teaming System (CATS) Warrior on January 11, 2025, ahead of Aero India 2025. Combat Air Teaming System (CATS) is an Indian unmanned and manned combat aircraft teaming system. Hindustan Aeronautics Limited (HAL) developed this system. The system enhances surveillance, strike capabilities, and reduces human error.

Notes:
The Ministry of Electronics & Information Technology (MeitY) and Data Security Council of India (DSCI) launched the second edition of the Cyber Security Grand Challenge (CSGC 2.0). The prize pool has been increased to Rs. 6.85 crores from Rs. 3.2 crores. Innovators, startups, and entrepreneurs are invited to address six key cybersecurity challenges, including API Security, Data Security, and AI for Threat Detection. Intellectual property rights for solutions developed will stay with startups. The competition has four stages, with winners receiving Rs. 25 lakh, and the overall winner getting Rs. 1 crore. The initiative supports Digital India and Atmanirbhar Bharat.
