Science & Technology Current Affairs MCQs

Notes:
Army Hospital (Research and Referral), Delhi, performed India’s first 3D Flex Aqueous Angiography with iStent. The procedure combines advanced imaging with minimally invasive glaucoma surgery. Glaucoma is a leading cause of irreversible blindness with silent progression. The surgery used a stand-mounted Spectralis system and a 3D operating microscope. The breakthrough allows real-time visualization of aqueous outflow pathways. Surgeons can deliver precise, targeted interventions, improving patient outcomes. The procedure positions Armed Forces Medical Services at the forefront of global ophthalmic care.

Notes:
The Union Minister Shri Rajiv Ranjan Singh inaugurated India’s first commercial-scale tropical Recirculating Aquaculture System (RAS)–based Rainbow Trout Aquaculture Farm & Research Institute on 5th January 2026 in Hyderabad, Telangana. The facility, established by Smart Green Aquaculture Limited at Kandukur Mandal, Ranga Reddy District, demonstrates year-round farming of high-value cold-water species like Rainbow Trout in tropical climates using precision engineering and advanced water recirculation technologies. The project serves as a live training and demonstration platform, providing youth hands-on experience in advanced aquaculture systems, automation, and biosecurity, strengthening human capital in the fisheries sector.

Notes:
Scientists used first images from the Vera C. Rubin Observatory to discover the fastest-spinning asteroid of its size, named 2025 MN45. The Vera C. Rubin Observatory is located on Cerro Pachón in the Chilean Andes at 8,684 feet altitude. It is named after astronomer Vera C. Rubin, who provided early evidence for dark matter. It is jointly funded by the United States National Science Foundation (NSF) and the United States Department of Energy (DoE). Its goals include studying dark matter and dark energy, mapping the Milky Way, tracking asteroids and comets, and observing changing cosmic objects.

Notes:
The United States Food and Drug Administration (FDA) approved Zycubo, a copper histidinate injection, as the first treatment for Menkes disease in children. Menkes disease is a rare genetic disorder that affects the body’s ability to process copper. It is caused by mutation of the ATP7A gene located on the X chromosome, affecting copper transport and balance. Copper is essential for metabolism, brain function, blood formation, immunity, wound healing, and iron use. The disease leads to low copper levels in blood, liver, and brain, reducing copper-dependent enzyme activity.

Notes:
Voyager 1 is a space probe launched by National Aeronautics and Space Administration (NASA) in 1977 to explore the outer planets. Recent news highlights that Voyager 1 is expected to become the first human-made object to reach a distance of one light-day from Earth. One light-day means the distance light travels in 24 hours, showing how far the spacecraft has gone. Voyager 1 is already the most distant human-made object and is travelling through interstellar space. It crossed the heliosphere and entered interstellar space in August 2012. Its mission earlier included flybys of Jupiter and Saturn, studying their moons, rings, and magnetic fields.

Notes:
A Guillain-Barré Syndrome (GBS) outbreak has been reported in Neemuch district of Madhya Pradesh, with two deaths in Manasa town. Guillain-Barré Syndrome is a rare neurological disorder in which the body’s immune system attacks the peripheral nervous system. The peripheral nervous system is the network of nerves outside the brain and spinal cord that controls movement, pain, and sensations. Since the immune system causes the damage, it is an autoimmune disease, also called acute inflammatory demyelinating polyradiculoneuropathy.

Notes:
Recently, a new microscopic crustacean named Indiaphonte bijoyi was discovered in the Kavaratti lagoon of the Lakshadweep islands. It is a tiny crustacean belonging to the family Laophontidae under the Copepoda class. The species lives within sediments of aquatic environments, making it a sediment-dwelling organism. It has a semi-cylindrical and slightly flattened body, broader at the centre and narrowing towards the rear end. It is classified as meiofauna, meaning very small invertebrate animals measuring less than one millimetre in size.

Notes:
A 19-year-old college girl in Tamil Nadu died after consuming borax for weight loss. Borax is also called sodium tetraborate decahydrate, a white powdery mineral. It is composed of boron, sodium, and oxygen. It is used in glass and pottery glazes, metallurgy, welding flux, fertilizer additive, soap, disinfectant, mouthwash, and water softener. It naturally occurs in evaporite deposits from seasonal lake evaporation and can be synthetically produced.

Notes:
Andhra Pradesh Chief Minister N. Chandrababu Naidu launched Pilloo AI, a voice-based billing and accounting assistant for businesses. The app allows users to create invoices, record transactions, generate reports, and manage accounts by speaking in their native language. No prior accounting knowledge or complex software is required, saving time and reducing manual effort. Pilloo AI supports five Indian languages and can record daily sales and payments, generate balance sheets, receivables, and payables. It automates purchase and bank transaction entries by extracting data from uploaded bills and bank statements.

Notes:
India entered the quantum era with the launch of the Amaravati Quantum Valley on 8 February 2026. It is supported by the ₹6,000 crore National Quantum Mission to make India a global deep-tech power. The Amaravati Quantum Valley is India’s first integrated quantum ecosystem spread over 50 acres. It brings together government, universities, and companies like International Business Machines (IBM) and Tata Consultancy Services (TCS). It is located in Andhra Pradesh. It will support healthcare, finance, defence, secure communication, and create jobs while strengthening national security.
