Science & Technology Current Affairs MCQs

Notes:
Researchers at Nagaland University discovered that Sinapic acid significantly accelerates wound healing in diabetic conditions. Sinapic acid is a natural phenolic acid derived from cinnamic acid. It has antioxidant, antitumor, anti-inflammatory, antibacterial, and neuroprotective properties. It is found in spices, citrus and berry fruits, vegetables, cereals, and oilseed crops. The compound activates the SIRT1 (Sirtuin 1) pathway, aiding tissue repair, angiogenesis, and inflammation control. This discovery could lead to safe, natural, and effective diabetic wound treatments. Diabetic wounds are slow-healing sores, mostly on the foot, increasing risk of neuropathy, poor circulation, infections, and amputation. Diabetes mellitus is a metabolic disease causing high blood glucose levels and affects hundreds of millions globally.

Notes:
Defence Minister Rajnath Singh inaugurated the Titanium and Superalloy Materials Plant at PTC Industries, Lucknow, marking a big step towards self-reliance in defence materials. The plant is part of the Strategic Materials Technology Complex under Aatmanirbhar Bharat vision. The plant will help make components for fighter jets, missiles, naval systems, and satellites. The plant will help make components for fighter jets, missiles, naval systems, and satellites. It supports the Uttar Pradesh Defence Industrial Corridor, generating jobs for youth, MSMEs, and start-ups.

Notes:
Google announced that its quantum processor Willow has achieved the first “verifiable” quantum advantage. Quantum advantage means a quantum computer can outperform a classical computer in practice. The announcement was accompanied by an open-access paper in Nature by the Google Quantum AI and Collaborators team. Willow ran a new algorithm, Quantum Echoes, 13,000 times faster than the best classical algorithm on a supercomputer. The experiment used a technique called out-of-time-order correlator (OTOC) to track how information scrambles in quantum systems. OTOC measures how quantum information spreads, is scrambled, and can be “unscrambled” using time-reversal. Willow’s processor precisely controlled quantum bits (qubits) in a chaotic quantum system for the experiment.

Notes:
The Indian Space Research Organisation (ISRO) successfully launched the LVM3-M5 rocket from Satish Dhawan Space Centre, Sriharikota at 5:35 pm. The rocket carried CMS-03, India’s heaviest communication satellite weighing 4,400 kilograms. It was the fifth operational flight of the Launch Vehicle Mark-3 (LVM3) launcher. CMS-03 was launched into a Geosynchronous Transfer Orbit (GTO). The satellite will provide multi-band communication services across India and nearby ocean regions. It will enhance secure data, voice, and video connectivity for civilian and strategic applications. The mission highlights India’s capability in heavy satellite launches and strengthens its communication network.

Notes:
In November 2025, Google announced ‘Project Suncatcher,’ a research initiative to create a solar-powered, space-based AI infrastructure system. The project aims to use Tensor Processing Units (TPUs) aboard satellites in low-Earth orbit (LEO) to explore machine learning scalability. It will use Trillium TPUs designed to withstand up to 15 krad(Si) radiation and advanced thermal radiators to manage heat. In partnership with Planet Labs, two prototype satellites will launch in 2027 to test AI performance and optical communication. Solar-powered satellites will operate in a sun-synchronous dawn-dusk orbit, generating up to 8 times the power of ground-based installations

Notes:
Shri Manohar Lal, Minister of Power and Housing & Urban Affairs, inaugurated India’s first and largest Vanadium Redox Flow Battery (VRFB) system. The VRFB has a capacity of 3 Megawatt-hour (MWh) at NTPC’s NETRA Research & Development Centre in Greater Noida. This milestone advances India’s long-duration energy storage (LDES) solutions and strengthens renewable energy integration and national grid resilience. Vanadium Redox Flow Battery (VRFB) is a modern technology offering an alternative to lithium-ion batteries, expanding the pool of usable elements for battery systems.

Notes:
Recently, the World Health Organization (WHO) confirmed Ethiopia’s first-ever outbreak of Marburg Virus Disease (MVD). MVD is a severe and often fatal hemorrhagic fever caused by the Marburg virus. It was first identified in 1967 in Marburg, Germany. The causative agents are Marburg virus (MARV) and Ravn virus (RAVV) of the species Orthomarburgvirus marburgense. The natural host is the fruit bat Rousettus aegyptiacus of the Pteropodidae family. It spreads from infected bats to humans and then through contact with bodily fluids or contaminated surfaces.

Notes:
In November 2025, Union Minister of State Dr. Jitendra Singh launched India’s first indigenous high-precision compact diode laser at the Emerging Science, Technology and Innovation Conclave 2025 (ESTIC 2025) held at Bharat Mandapam, New Delhi. The laser enables quantum-encrypted communication using Quantum Key Distribution (QKD), strengthening cybersecurity for financial and banking transactions. It is developed by Prenishq Pvt. Ltd., a startup supported by the National Quantum Mission (NQM), along with contributions from IIT-Delhi. The system offers high beam quality, strong stability, long-term reliability, and easy integration with lab and industrial setups.

Notes:
Union Minister of State (Independent Charge) for Science & Technology, Dr. Jitendra Singh, launched Hansa-3(NG), first indigenous all-composite two-seater trainer aircraft for Private Pilot License (PPL) and Commercial Pilot License (CPL) training at CSIR–National Aerospace Laboratories (NAL), Bengaluru. Hansa-3(NG) reduces foreign dependence and boosts aviation entrepreneurship. The aircraft will help flying clubs meet India’s growing demand for trained pilots.

Notes:
Niger became the first country in the African Region to eliminate onchocerciasis, also called river blindness. Niger is the fifth country worldwide to stop transmission of Onchocerca volvulus parasite. Other successful countries are Colombia, Ecuador, Guatemala, and Mexico in the Americas. World Health Organisation (WHO) praised Niger’s strong leadership and public health efforts. Onchocerciasis is the second leading infectious cause of blindness after trachoma. It spreads through bites of infected black flies found near rivers. It mainly affects rural areas of sub-Saharan Africa and Yemen, and some parts of Latin America.
