Science & Technology Current Affairs MCQs

Notes:
India launched DHRUV64, the country’s first 1.0 GHz, 64-bit dual-core microprocessor, fully developed by the Centre for Development of Advanced Computing (C-DAC) under the Microprocessor Development Programme. DHRUV64 aims to reduce India’s dependence on imported processors and supports both strategic and commercial applications. The processor features modern architectural enhancements for improved efficiency, multitasking, and reliability, and integrates seamlessly with hardware for applications like 5G, automotive systems, consumer electronics, industrial automation, and the Internet of Things. India contributes nearly 20% to global microprocessor production, highlighting the importance of indigenous chip development.

Notes:
The Indian Space Research Organisation (ISRO) recently launched RESPOND Basket 2025. The programme invites research proposals from premier universities and recognised academic and R&D institutions. It focuses on areas relevant to ISRO’s upcoming missions and national priorities. RESPOND Basket 2025 supports projects including the Bharatiya Antariksh Station, Chandrayaan-4, Gaganyaan missions, Venus orbiter, and a human Moon landing. The initiative aims to strengthen collaboration between ISRO and academic institutions and foster research aligned with India’s space ambitions.

Notes:
National Aeronautics and Space Administration (NASA) has lost contact with the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft. MAVEN is a Mars orbiter that studied how the planet’s atmosphere escapes into space for over ten years. It is the first mission dedicated to studying the upper atmosphere of Mars. It is part of NASA’s Mars Exploration Program to understand Mars and its past habitability. The mission studied how atmospheric loss changed Mars’s climate over time.

Notes:
IIT Delhi researchers developed an Artificial Intelligence (AI)-based system called AILA (Artificially Intelligent Lab Assistant). AILA works on an AI Agentic Framework and can perform real scientific experiments like a human scientist. It has a simple chat interface where instructions in English are converted into code to execute experiments. The system has been demonstrated on an Atomic Force Microscope (AFM), a key instrument in material research. AILA can control the AFM, make real-time decisions during experiments, and analyse results independently. The technology can save time, reduce manpower requirements, and transform India’s scientific research ecosystem.

Notes:
Abu Dhabi, United Arab Emirates (UAE),’s Sheikh Khalifa Medical City became the first hospital worldwide to administer ITVISMA gene therapy. ITVISMA is a one-time gene therapy for spinal muscular atrophy (SMA), given on 28 December 2025. It replaces the defective Survival Motor Neuron 1 (SMN1) gene. This enables production of survival motor neuron protein, targeting the root genetic cause. It is approved for patients aged two years and above, including adults. Spinal Muscular Atrophy (SMA) is a rare, progressive neuromuscular disorder causing muscle weakness and life-threatening complications. The therapy may improve motor function and reduce long-term treatment dependence.

Notes:
India will demonstrate in-orbit satellite refuelling for the first time with OrbitAid’s AyulSAT launched on ISRO’s PSLV-C62. AyulSAT is a 25-kg dedicated tanker and target satellite developed by Chennai-based OrbitAid Aerospace, founded by Sakthikumar Ramachandran. It is designed to demonstrate fuel, power, and data transfer in orbit using a standardized docking and refuelling interface. The satellite will first perform internal refuelling to study fluid behaviour in microgravity. It uses OrbitAid’s Standard Interface for Docking and Refuelling Port (SIDRP) for future spacecraft-to-spacecraft refuelling.

Notes:
Recently, Google Research unveiled Project Suncatcher to address rising electricity demand from Artificial Intelligence (AI). Project Suncatcher proposes placing AI datacentres in low-Earth orbit (LEO) powered entirely by solar energy. It aims to reduce AI’s energy footprint and reduce dependence on Earth-based power grids, land, and water. The system uses clusters of satellites in sun-synchronous orbits to receive continuous sunlight. AI workloads run across satellites using ultra-high-bandwidth inter-satellite links. Only data inputs and outputs are sent to Earth. It relies on radiation-tolerant Tensor Processing Units (TPUs) and special thermal designs to work in space.

Notes:
Recently, lunar regolith brought by China’s Chang’e-6 mission revealed that the Moon formed from the remains of an ancient collision with Earth. Chang’e-6 is China’s first human sampling and return mission from the Moon’s far side, part of the Chang’e lunar exploration program. It was launched on 3 May 2024 via Long March-5 rocket from Wenchang Space Launch Center, Hainan. The mission includes an orbiter, returner, lander, and ascender. The lander used sensors (microwave, laser, optical) and collected samples via drilling and a robotic arm. It is China’s second successful mission to the Moon’s far side after Chang’e-4 in 2019.

Notes:
Indian Institute of Technology (IIT) Kanpur researchers developed a new method to predict solar cycles. A solar cycle is an about 11-year cycle of solar activity controlled by the Sun’s magnetic field. It is measured by the number and intensity of sunspots seen on the Sun’s surface. Around every 11 years, the Sun’s magnetic field flips, swapping north and south poles. Sunspots increase and decrease as magnetic activity changes on the Sun. The cycle starts with solar minimum, when sunspots are very few. Activity rises to solar maximum, when sunspots are highest. After this, activity declines back to solar minimum and a new cycle begins.

Notes:
Researchers discovered a new marine worm species named Paraleocrates indica in the muddy banks of the Champa Estuary in the Bay of Bengal. It is the first record of this rare genus from Indian waters and only the third species worldwide in this genus. The worm belongs to the Hesionidae family, known for colourful bristle worms that often live symbiotically with other marine organisms like starfish. It appears reddish, measures 14–35 millimetres, and has a unique eye structure with front eyes five times larger than the back ones.
