Science & Technology Current Affairs MCQs

Notes:
Indian Institute of Technology, Madras (IIT-Madras) has been nominated as a United Nations (UN) Centre of Excellence (COE) for Artificial Intelligence (AI), capacity building, and skilling. The nomination was announced by Ministry of Electronics and Information Technology (MeitY) Secretary S Krishnan at the 80th UN General Assembly in New York. The Centre of Excellence will operate under the UN Office for Digital and Emerging Technologies (ODET) to support the Global South in AI capacity building. India’s AI mantra is “capacity is the new connectivity” to bridge global AI gaps.

Notes:
Recently, Central University of Rajasthan (CUoR) conducted the first successful wheat cultivation in arid land using desert ‘soilification’ technology. The experiment aims to stop the expansion of western Rajasthan’s Thar desert towards the National Capital Region. Desert sand was converted into soil using polymers and indigenous bioformulation, enhancing water retention and soil structure. The project was supported by Krishi Vigyan Kendra (KVK) and the State Horticulture Department. The experiment proves that even barren desert land can become productive with biotechnology.

Notes:
A new 3D map of stellar nurseries has been created using data from the Global Astrometric Interferometer for Astrophysics (GAIA) telescope. The map covers star-forming regions within 4,000 light-years of the Sun in all directions. It shows glowing hydrogen gas clouds, helping scientists study star formation and interstellar gas dynamics. The study combines Gaia dust maps with radiation effects from 87 massive O-type stars emitting ultraviolet light that ionises hydrogen gas. The simulation aligns with older hydrogen emission maps but provides higher precision. GAIA, launched in 2013 by the European Space Agency (ESA), aims to create the most precise 3D map of the Milky Way Galaxy. The telescope is positioned at Lagrange Point 2 (L2), 1.5 million km from Earth, for a stable cosmic view.

Notes:
Researchers recently found that carabid ground beetles can act as bioindicators to track soil microplastics. They are commonly called ground beetles and belong to the Carabidae family. These beetles play a key role in the food web as both predators and prey species. They live in diverse habitats such as forests, grasslands, agricultural fields, wetlands, and urban areas. They thrive in temperate to tropical climates. Ecologically, they help in biological pest control and now aid in monitoring soil pollution.

Notes:
Kerala reported another death from Amoebic Meningoencephalitis (Primary Amebic Meningoencephalitis, PAM), raising the 2025 toll to 27 cases. Primary Amebic Meningoencephalitis is a rare, fatal brain infection caused by the free-living amoeba Naegleria fowleri, known as the “brain-eating amoeba.” Infection occurs when contaminated freshwater enters the nasal cavity, allowing the amoeba to reach the brain via the olfactory nerve. It is found in warm freshwater and soil, especially lakes, rivers, hot springs, and unchlorinated pools.

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 Cochin University of Science and Technology (CUSAT) has received a national patent for a machine learning-based radar technology to extract accurate rainfall data. The system was developed at the Advanced Centre for Atmospheric Radar Research (ACARR). It uses a Hybrid Adaptive Bi-Gaussian Fitting Algorithm with a Gaussian Mixture Model (GMM) to separate rain and air turbulence echoes. The innovation helps radars clean their data in real time, improving rainfall and wind accuracy up to 5 km in the troposphere. It enhances flood forecasting and early warning systems for Kerala, a state prone to extreme monsoon events.

Notes:
Chinese researchers discovered tiny Iron oxide crystals (hematite and maghemite) in lunar soil for the first time using samples from China’s Chang’e-6 mission. The finding from the South Pole–Aitken (SPA) Basin challenges the old belief that the Moon’s reducing environment cannot form oxidized minerals. Chang’e-6 was the sixth robotic lunar exploration mission by the China National Space Administration (CNSA). The study in Science Advances confirms direct evidence of Iron oxide on the Moon. Scientists say massive ancient impacts created oxygen-rich vapour, leading to “vapour-phase deposition” of hematite crystals. These minerals, including maghemite, may explain magnetic anomalies in the SPA Basin. The breakthrough offers new insights into lunar history, composition, and future missions

Notes:
India’s first indigenous CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-based gene therapy for Sickle Cell Disease (SCD), named BIRSA 101, was recently launched by the Union Minister of State (Independent Charge) for Science & Technology. It is developed by CSIR (Council of Scientific and Industrial Research) – Institute of Genomics and Integrative Biology (IGIB). BIRSA 101 uses CRISPR-Cas9 gene-editing technology to precisely correct the genetic mutation causing SCD. The therapy is administered as a one-time infusion, after which the body produces normal red blood cells instead of sickle-shaped ones.

Notes:
Skyroot Aerospace inaugurated its Infinity Campus in Hyderabad and virtually unveiled Vikram-I, India’s first private commercial orbital rocket. Vikram-I is capable of placing satellites into Earth orbit. This launch marks a major milestone for India’s growing private space sector. The private space sector in India was opened to entrepreneurs three years ago. The development highlights rising startup participation in advanced space technology. It reflects India’s shift toward innovation-driven and private-led space missions.
