Science & Technology Current Affairs MCQs

Notes:
The Defence Research and Development Organisation (DRDO) inaugurated the Quantum Technology Research Centre (QTRC) at Metcalfe House, New Delhi on May 27, 2025. Quantum Technology Research Centre (QTRC) aims to strengthen India’s indigenous capabilities in quantum science for defence and strategic purposes. It houses advanced experimental setups for research in crucial quantum domains. It also has test-beds for single-photon sources and platforms for Quantum Key Distribution to ensure ultra-secure communication. DRDO continues to lead India’s efforts in quantum sensing, post-quantum cryptography, and secure communications. As a core partner in the National Quantum Mission, DRDO promotes indigenous innovation in sovereign quantum technologies.

Notes:
Recently, three new startups were selected to build India’s own Foundation Model under the IndiaAI Mission, marking a big step in boosting local Artificial Intelligence (AI) capabilities. The IndiaAI Mission was launched in 2023 as a joint effort by the Ministry of Electronics and Information Technology (MeitY) and the National Association of Software and Service Companies (NASSCOM). It supports startups and researchers by providing access to high-end computing power. The mission promotes “Making AI in India” by developing AI technologies locally.

Notes:
The central government recently notified 34 biostimulants to boost their production and use in agriculture. Biostimulants are natural substances or microorganisms applied to plants or soil to enhance the plant’s natural growth and stress-resistance processes. They help reduce dependence on fertilizers by improving nutrient use efficiency, root growth, and resistance to drought, salinity, and extreme temperatures. In India, biostimulants are regulated under the Fertilizer (Control) Order, 1985.

Notes:
New research revealed the largest diphtheria outbreak in Western Europe in 70 years started in 2022. The outbreak mainly affected vulnerable groups like migrants and the homeless. Diphtheria is a highly contagious bacterial infection caused by bacteria Corynebacterium diphtheriae. This bacteria produces a toxin that attacks the respiratory tract and can spread through the body. Transmission occurs through respiratory droplets from coughing or sneezing. It can also spread by contact with infected open sores or ulcers on the skin.

Notes:
China has launched the Zhangheng 1B satellite to strengthen early warning systems for natural disasters by monitoring Earth’s electromagnetic environment. It was launched aboard a Long March 2D rocket from the Jiuquan Satellite Launch Center in the Gobi Desert. Developed in partnership with Italy under a 2019 cooperation agreement, the satellite entered orbit as planned. Zhangheng 1B is China’s first satellite focused on studying geophysical fields from space and will work with Zhangheng 1A launched in 2018. It carries nine instruments, including an electric field detector and a high-energy particle sensor built by Italy.

Notes:
Researchers recently found a surprising amount of germanium in a star named A980, which is part of a rare group called Extreme Helium (EHe) stars. This is the first time germanium, a metallic element, has been observed in such a star. Extreme Helium stars are low-mass supergiants that have very little hydrogen and are mostly made of helium. They are believed to form from the merger of a carbon-oxygen white dwarf and a smaller helium white dwarf. Only 21 EHe stars have been found in our galaxy so far.

Notes:
A recent genomic study revealed the spread of Rice Yellow Mottle Virus or RYMV across African rice ecosystems, posing a serious threat to rice production. Rice Yellow Mottle Virus is a plant virus that affects rice and some related grasses. It first appeared in the mid-1800s in the Eastern Arc Mountains, now in Tanzania, a region rich in biodiversity. It is mainly found in Africa and is present in most rice-growing countries on the continent.

Notes:
Recently, Google DeepMind launched a new Artificial Intelligence model called AlphaGenome. AlphaGenome aims to predict accurately how individual mutations in human Deoxyribonucleic Acid (DNA) affect their functions and impact human health. It is built on DeepMind’s earlier genomics model named Enformer and works alongside AlphaMissense, which focuses on classifying the effects of variants in protein-coding regions. The model can analyze very long DNA sequences up to one million base pairs and generate highly detailed predictions.

Notes:
Recently, the Indian Council of Medical Research (ICMR) decided to expand its Mobile Biosafety Level-3 (MBSL-3) laboratory network to boost India’s outbreak response and public health. The Mobile BSL-3 lab is also called Rapid Action Mobile BSL-3 Advanced Augmented Network (RAMBAAN). It is an advanced “lab on wheels” developed under the Pradhan Mantri Ayushman Bharat Health Infrastructure Mission. It was first used during the Nipah virus outbreak in Kerala in 2023.

Notes:
Recently, the Minister of State for Communications and Rural Development launched the high-capacity SAKSHAM-3000 to boost self-reliance and global competitiveness. SAKSHAM-3000 is a compact 25.6 Terabits per second (Tbps) switch-router developed by Centre for Development of Telematics (C-DOT). It is built for modern data centres, large enterprises, telecom operators, and hyperscale data centres. It has ultra-low latency, wire-speed processing, and uses the modular C-DOT Router Operating System (CROS).
