Science & Technology Current Affairs MCQs

Notes:
On November 17, 2025, Karnataka’s Department of Electronics, IT & BT, with KEONICS, launched KEO, a compact, affordable and AI-ready personal computer designed entirely in Karnataka. KEO stands for Knowledge-driven, Economical, Open-source, built on an open-source RISC-V processor with a Linux-based OS. It features an on-device AI core that works without internet and includes BUDDH, an AI agent trained on the Karnataka DSERT syllabus to help students in low-connectivity areas. KEO will be deployed across schools, universities, businesses, homes and government offices, supporting locally adaptable, home-grown computing.

Notes:
The Assam Government recently banned inter-district movement of live pigs to stop the spread of African Swine Fever (ASF), a rising concern in the region. African Swine Fever (ASF) is a highly contagious and deadly viral disease affecting pigs and wild boar, with mortality up to 90–100%. It is not zoonotic, meaning it does not infect humans or other livestock. First found in sub-Saharan Africa, ASF is now present across Europe, Asia and Africa, with India reporting its first cases in 2020 in Assam and Arunachal Pradesh.

Notes:
Russia successfully launched a new set of undisclosed military satellites. The launch vehicle used was the Angara-1.2 light rocket. It was conducted from Plesetsk Cosmodrome. Plesetsk is the world’s northernmost spaceport. The exact number and purpose of the satellites were not disclosed. The mission was carried out for the Russian Defence Ministry. It was executed by a combat crew of the Aerospace Forces.

Notes:
ISRO Chairman V Narayanan inaugurated Ananth Technologies’ Ananth Centre of Excellence for Navigation (ACEN) in Thiruvananthapuram. ACEN is India’s first private-sector navigation innovation hub. Ananth Technologies, founded in 1992, contributes to ISRO and Defence Research and Development Organisation (DRDO) missions with expertise in precision sensors, airworthiness, and system integration. Navigation is crucial for missiles, aircraft, ships, and satellites; reliance on foreign GPS revealed strategic vulnerabilities. ACEN will handle Maintenance, Repair, and Overhaul (MRO) of navigation systems domestically.

Notes:
The National Human Rights Commission (NHRC) reported that 97 central and state laws still have provisions discriminating against persons affected by leprosy. Leprosy (Hansen’s disease) is a chronic bacterial infection caused by bacteria Mycobacterium leprae affecting skin, peripheral nerves, and eyes, which can cause permanent disabilities if untreated. The bacteria spread through droplets from the nose and mouth during close, frequent contact with untreated cases. India’s prevalence rate decreased from 57.2 per 10,000 in 1981 to 0.57 per 10,000 in 2025, achieving national elimination status in 2005.

Notes:
Aditya-L1, India’s first solar observatory, helped scientists understand why the May 2024 solar storm — the strongest in 20+ years — behaved unusually. A solar storm is a sudden burst of particles, energy, magnetic fields, and solar material ejected by the Sun. It is caused when the Sun’s twisted magnetic fields become overstretched and snap in a magnetic reconnection, releasing huge energy. Solar storms can produce a solar flare, radiation storm, or a coronal mass ejection (CME).

Notes:
NewSpace India Limited (NSIL), the commercial arm of the Indian Space Research Organisation (ISRO), has signed 70 Technology Transfer Agreements with industry. NSIL was incorporated on 6 March 2019 under the Companies Act, 2013, and works under the Department of Space (DOS), Government of India. It helps Indian industries take up high-technology space activities and promotes commercial use of India’s space products and services.

Notes:
Scientists at the Bose Institute, Kolkata have developed GlowCas9, a CRISPR protein that glows during gene editing. It is a bioluminescent Cas9, created by fusing Cas9 with a split nano-luciferase enzyme from deep-sea shrimp proteins. GlowCas9 is highly stable, retaining structure and activity even at higher temperatures. When Cas9 folds correctly, the luciferase pieces reconnect and produce light, enabling real-time, non-harmful tracking of gene editing in cells, tissues, and plant leaves. It improves the precision of Homology-Directed Repair (HDR), a key DNA repair process for genetic diseases like sickle cell anaemia and muscular dystrophy. GlowCas9 advances theratracking, the visual monitoring of molecular gene therapy in action.

Notes:
Kavach is an indigenously developed Automatic Train Protection (ATP) system designed to improve railway operational safety across the Indian Railways network. It was developed by the Research Design and Standards Organisation (RDSO) of Indian Railways. As of December 2025, the system has been commissioned on over 2,000 km of railway routes, with 7,129 km of Optical Fibre Cable (OFC) laid, 860 telecom towers installed, 767 stations connected, 3,413 km of trackside equipment deployed, and 4,154 locomotives fitted with Kavach. About 40,000 technicians and operators have been trained, reflecting the scale of operational readiness.

Notes:
IIT Delhi researchers developed an Artificial Intelligence (AI)-based system called AILA (Artificially Intelligent Lab Assistant). AILA works on an AI Agentic Framework and can perform real scientific experiments like a human scientist. It has a simple chat interface where instructions in English are converted into code to execute experiments. The system has been demonstrated on an Atomic Force Microscope (AFM), a key instrument in material research. AILA can control the AFM, make real-time decisions during experiments, and analyse results independently. The technology can save time, reduce manpower requirements, and transform India’s scientific research ecosystem.
