Science & Technology Current Affairs MCQs

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:
ISRO launched the “Space Docking Experiment” (SpaDeX) mission on 30 December from Sriharikota’s Satish Dhawan Space Centre. The mission aims to develop technology for docking, undocking, and power transfer between spacecraft. Two small spacecraft, SDX01 (Chaser) and SDX02 (Target), each weighing 220 kg, will dock in a 476-km low-Earth orbit. The launch vehicle for this mission is Polar Satellite Launch Vehicle-C60 (PSLV-C60). The mission uses the indigenous “Bharatiya Docking System” and will make India the fourth country to achieve this feat. SpaDeX will support India’s future space exploration goals, including lunar missions and the Bharatiya Antariksha Station.

Notes:
Researchers using South Africa’s MeerKAT radio telescope detected a loud gravitational wave background through the MeerKAT Pulsar Timing Array. The gravitational wave background’s “hot spot” in the Southern Hemisphere was mapped in unprecedented detail. MeerKAT is a radio telescope array in Northern Cape, South Africa, originally called the Karoo Array Telescope (KAT). Initially planned with 20 receptors, it was expanded to 64 receptors and renamed “MeerKAT,” meaning “more of KAT.” It is part of South Africa’s contribution to the global Square Kilometre Array (SKA) project, the world’s largest radio telescope initiative.

Notes:
AnemiaPhone, developed by Cornell University, is now part of Indian Council of Medical Research (ICMR) programs for anemia, women’s health, and maternal and child health in India. It offers quick, accurate, and low-cost iron deficiency assessment. Anemia affects 50% to 70% of pregnant women in India, with iron deficiency as the main cause. The device uses a drop of blood on a test strip, similar to a COVID-19 test, providing results in minutes. Data is uploaded to a clinical database via mobile devices, enabling healthcare workers to provide immediate guidance, referrals, or interventions.

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:
India has officially banned nimesulide after research confirmed its toxic impact on endangered vultures. Nimesulide is a non-steroidal anti-inflammatory drug (NSAID) used for pain and inflammation relief in conditions like osteoarthritis, menstrual cramps, and fever. The drug was widely used for treating animals like cattle, pigs, and horses. It causes kidney damage in vultures, leading to health issues and a decline in their population. Symptoms like visceral gout indicate kidney damage in vultures. Nimesulide is banned for pediatric use in several countries and now in India under the Drugs and Cosmetics Act, 1940.

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:
The ISRO mission that successfully germinated lobia seeds (also known as cowpea seeds) in space is called the “CROPS” experiment, which stands for “Compact Research Module for Orbital Plant Studies”. The seeds sprouted on the fourth day, with leaves visible by the fifth day, marking a major milestone in space research. The experiment aims to develop sustainable food sources for long-term space missions and test plant growth in microgravity and controlled environments. Success supports astronauts by enabling food growth, oxygen generation, and CO₂ recycling in space. It highlights India’s capability in managing complex life-support systems and contributes to global space farming initiatives.
