Science & Technology Current Affairs MCQs

Notes:
Indian scientists from Centre for Nano and Soft Matter Sciences, Bengaluru under Department of Science and Technology (DST) developed a solar-powered energy storage device that captures and stores energy in a single unit. The device is known as a photo-rechargeable supercapacitor. Unlike conventional systems, it combines energy harvesting and storage, reducing cost, energy loss, system complexity, and footprint. It enables portable, wearable, off-grid applications, reduces reliance on fossil fuels and conventional batteries, and works in remote areas.

Notes:
Union Minister Dr. Jitendra Singh launched the first open call of the Technology Development Board (TDB) under the Research, Development and Innovation (RDI) Fund. The initiative has been launched under the Anusandhan National Research Foundation (ANRF) to support indigenous technology commercialisation. The RDI Fund provides long-term, low-interest financing to high-risk, high-impact private sector innovations. It has a corpus of ₹1 lakh crore with 2–4 percent interest and repayment up to 15 years. The first call targets Technology Readiness Level (TRL) 4 and above projects in areas like artificial intelligence and deep-tech.

Notes:
The European Space Agency (ESA) released a high-resolution satellite image through the Copernicus Sentinel-2 mission. The image captures the venues planned for the 2026 Winter Olympic Games. The image highlights land features, terrain, and human-made infrastructure in great detail. The Copernicus Sentinel-2 mission is an Earth observation satellite mission developed by the European Space Agency (ESA). It is part of Copernicus, the European Union’s Earth observation programme. The mission focuses on monitoring changes and variability in land surface conditions.

Notes:
Waaree Energies will set up India’s largest lithium-ion battery gigafactory at Rambilli, Anakapalli district, Andhra Pradesh. Total investment is ₹8,175 crore for a greenfield project. The plant will have 16 Gigawatt-hour (GWh) capacity. It will cover full battery value chain: cell manufacturing, battery packs and Battery Energy Storage Systems (BESS). It received in-principle approval from State Investment Promotion Board. The project supports clean-energy goals of Andhra Pradesh.

Notes:
Zimbabwe has started rolling out Lenacapavir for HIV prevention. It is the first twice-yearly injectable pre-exposure prophylaxis (PrEP) for Human Immunodeficiency Virus (HIV). PrEP is a medicine taken by HIV-negative individuals to reduce the risk of HIV infection. Clinical studies show it prevents about 99.9 percent of HIV transmission. It is developed by Gilead Sciences and marketed as Yeztugo. Lenacapavir is a capsid inhibitor that blocks the virus’s protein shell needed for replication.

Notes:
The Indian Institute of Science (IISc), Bengaluru, has launched a “moonshot” research project to develop brain co-processors, which will combine neuromorphic hardware and artificial intelligence algorithms to enhance or restore human brain functions. The initiative is financially supported by the Pratiksha Trust. The project aims to develop both implantable and non-invasive brain co-processors capable of decoding neural signals from brain recordings, processing these signals using AI algorithms, and sending them back to the brain through neural stimulation or neurofeedback.

Notes:
Under Swachh Bharat Mission–Urban 2.0, Thiruvananthapuram Municipal Corporation deployed the AI-powered G-SPIDER robot for safe, human-free canal cleaning in high-risk areas. The robot was commissioned at the Amayizhanchan Canal near Thampanoor Railway Station, a stretch with restricted vertical clearance, continuous water flow, and unsafe human entry points. G-SPIDER is developed by Genrobotic Innovations, based on Cable-Driven Parallel Robotics (CDPR) architecture with AI-enabled vision and sensor intelligence. It autonomously detects, assesses, and removes mixed and hazardous waste using a five-degrees-of-freedom robotic mechanism with a biomimetic claw-type grabber.

Notes:
A new study found that Double Asteroid Redirection Test (DART) not only changed the motion of an asteroid but also slightly altered the orbit of the asteroid pair around the Sun. DART was launched in 2021 by National Aeronautics and Space Administration (NASA) to test asteroid deflection technology. It was the first planetary defence mission to change an asteroid’s path using the kinetic impact method. The spacecraft targeted a binary asteroid system of Didymos and its moonlet Dimorphos. In 2022, the spacecraft intentionally crashed into Dimorphos to alter its orbit around Didymos. The impact successfully changed the asteroid’s motion, proving humans can potentially deflect hazardous near-Earth objects in space.

Notes:
Avataar is India’s first amphibious drone, launched on 5 March 2026 by AquaAirX Autonomous Systems. It can operate both in air and underwater, combining drone flight with submarine-like diving for surveillance. The project received ₹12.5 crore seed funding from Rainmatter. It has reached TRL-6 (Technology Readiness Level-6), meaning a working prototype tested in real environments. It is built with carbon fibre body and anti-corrosion coatings to resist saltwater damage.

Notes:
Delhi government and Indian Institute of Technology Madras are studying “smog-eating” photocatalytic road coatings to reduce air pollution. The coating neutralizes harmful gases like nitrogen dioxide and volatile hydrocarbons present in polluted air. It mainly uses Titanium dioxide which is low-cost, chemically stable and compatible with construction materials. Titanium dioxide-based materials help in gaseous depollution and environmental cleaning. Photocatalysis works by using light energy to break down harmful pollutants and organic waste into less toxic or harmless substances. This process helps improve air quality and contributes to cleaner environment.
