Science & Technology Current Affairs MCQs

Notes:
India’s Antariksh Venture Capital Fund will start investing in space startups from FY2027 to boost the private space sector. It is a close-ended fund registered with Securities and Exchange Board of India as a Category II Alternative Investment Fund (AIF). Key investor is Indian National Space Promotion and Authorization Centre under the Department of Space. The fund is sponsored by SIDBI Venture Capital Limited. The objective is to provide capital for space startups, support scaling, and promote commercialization of technologies.

Notes:
Scientists at the Bose Institute discovered a new gene regulation mechanism in Tuberculosis bacterium (Mycobacterium tuberculosis). Transcription is the process where DNA is copied into RNA by RNA Polymerase (RNAP) for protein synthesis. Earlier, bacteria were believed to follow the Sigma Cycle, where sigma factor binds RNAP to initiate transcription and then detaches. The study found that in TB bacteria, the sigma factor (σF) remains continuously attached to RNAP throughout transcription. This continuous binding helps activate survival genes, enabling bacteria to persist in hostile conditions inside the human body.

Notes:
Researchers from the University of Cambridge have developed a hafnium-oxide memristor, a brain-inspired nanodevice that can significantly reduce Artificial Intelligence (AI) energy consumption. A memristor (memory + resistor) is an electronic component whose resistance depends on past current flow, enabling it to “remember” previous electrical states. Unlike a conventional resistor, a memristor has variable resistance and retains its state even when the current is switched off. Memristors are nanoscale devices with low energy requirements and are commonly made using materials like titanium dioxide (TiO₂) between metal electrodes.

Notes:
Institute of Nano-Science and Technology, Mohali, developed a new material to detect nicotine and cotinine using fluorometric sensing. Fluorometric sensing is a technique that measures substances through fluorescent emission. The material “lights up” on contact with nicotine/cotinine, enabling quick detection. It is based on Iron-based Metal-Organic Framework (Fe-MOF), a nano-structured porous material. It detects even small amounts accurately, improving over traditional methods. The material is biocompatible (safe for living cells) and works at in-vitro stage.

Notes:
India achieved a milestone with a 500 MWe (Megawatt Electric) Prototype Fast Breeder Reactor at Kalpakkam attaining first criticality on April 6, 2026. Developed by Indira Gandhi Centre for Atomic Research and built by BHAVINI. It marks Stage-II of India’s 3-stage nuclear programme using uranium-plutonium mixed oxide fuel. Fast Breeder Reactors produce more fuel than they consume. India will become the 2nd country after Russia to operate commercial Fast Breeder Reactors.

Notes:
Andhra Pradesh Chief Minister N Chandrababu Naidu laid the foundation stone for the Google Cloud India AI Hub in Visakhapatnam. The project is part of a major collaboration involving Google Cloud, Adani Group, and Bharti Airtel. Google has committed an investment of USD 15 billion, making it one of India’s largest foreign direct investments. The AI data centre will have a capacity of 1 Gigawatt and will be built over 600 acres. It will enhance India’s artificial intelligence, cloud computing, and digital infrastructure.

Notes:
The Department of Telecommunications and National Disaster Management Authority are strengthening mobile-based disaster communication systems. The Integrated Alert System SACHET (System for Advanced Communication for Hazard Early-warning and Emergency Transmission) is operational across all States and Union Territories. It was developed by Centre for Development of Telematics and is based on the Common Alerting Protocol (CAP) recommended by the International Telecommunication Union. The system sends geo-targeted SMS alerts in multiple languages during disasters.

Notes:
GalaxEye has successfully launched Mission Drishti, the world’s first OptoSAR satellite. The satellite was launched aboard Falcon 9 from California, United States. Mission Drishti weighs about 190 kilograms and is the largest Earth observation satellite built by a private Indian company. It combines optical and Synthetic Aperture Radar (SAR) technology for all-weather, day-and-night imaging. The mission enhances India’s capabilities in Earth observation and strategic monitoring.

Notes:
South Korea has launched the Compact Advanced Satellite 500-2 (CAS500-2) on May 3, 2026. The satellite is an Earth-observation satellite also known as Next-Generation Medium Satellite No. 2. It was launched aboard Falcon 9 from Vandenberg Space Force Base in the United States. The mission was overseen by the Korea AeroSpace Administration. The launch was delayed for nearly four years due to changes from the Russia-Ukraine conflict. The satellite entered a sun-synchronous orbit at an altitude of about 498 kilometres. It successfully established communication with a ground station in Svalbard shortly after launch.

Notes:
The Indian Institute of Tropical Meteorology, Pune established an Urban Testbed and Aerosol Observatory at SRM Institute of Science and Technology under Mission Mausam. The facility was inaugurated in Chennai by Dr. M. Ravichandran, Secretary of the Ministry of Earth Sciences on 6 May 2026. The observatory contains around 15 advanced instruments worth more than ₹60 crore and can monitor nearly 50 atmospheric parameters. It will improve weather forecasting by studying aerosols, wind flow, temperature, sea breeze, land breeze, clouds, and rainfall patterns. The Chennai Urban Testbed is the first comprehensive observatory of its kind in India.
