Science & Technology Current Affairs MCQs

Notes:
Indian National Space Promotion and Authorization Centre (IN-SPACe) launched the Technology Advancement Fund (TAF) to boost private sector innovation in space. IN-SPACe is an autonomous agency under the Department of Space (DOS) that promotes private participation. TAF aims to fund cutting-edge technologies and commercialization in the space sector.

Notes:
Nvidia has unveiled a powerful AI system called Evo 2 for genetic research. Evo 2 is the largest publicly available AI model for genomic data. It was built using 2,000 Nvidia H100 processors on Amazon’s cloud with Arc Institute and Stanford University. It is trained on 9 trillion nucleotides from 128,000+ organisms, covering plants, animals, and bacteria.

Notes:
The Solar Ultraviolet Imaging Telescope (SUIT) on Aditya-L1 detected an X6.3-class solar flare, a highly intense solar eruption. SUIT is a remote sensing payload on ISRO’s Aditya-L1, India’s first solar mission. The mission was launched on September 2, 2023. Solar Ultraviolet Imaging Telescope (SUIT) is developed by Inter-University Center for Astronomy and Astrophysics (IUCAA), Pune with ISRO. SUIT captures full-disk and region-specific images of the Sun. It uses 11 calibrated filters across 200-400 nm wavelengths to study the Sun’s layers. It is positioned at Lagrange Point. It observes the Sun 24×7. SUIT studies solar atmosphere dynamics, focusing on jets, flares, filament evolution, and eruptions.

Notes:
IIT Madras researchers developed a framework to enhance protection of critical infrastructure from ballistic missile threats. The framework helps designers improve the ballistic resistance of reinforced concrete (RC) panels. Findings were published in the journal Reliability Engineering & System Safety. Researchers used computational simulations to study missile impacts on RC. RC is used in military bunkers, nuclear power buildings, bridges, and runways.

Notes:
ISRO recently conducted a successful hot test on the semi-cryogenic engine (SE2000), advancing towards finalizing the cryogenic stage. The semi-cryogenic engine (SCE) uses liquid oxygen (LOX) as an oxidizer and refined kerosene (RP-1) as fuel. ISRO is developing the 2000 kN thrust SCE for future heavy-lift launch vehicles. Kerosene is more cost-effective and easier to handle than liquid hydrogen, simplifying storage and reducing mission costs. The engine will enhance ISRO’s launch vehicle payload capacity and is planned for use in the Next Generation Launch Vehicle (NGLV).

Notes:
IIT Bombay and Monash University, Australia, have developed a cost-effective sensor to detect toxic metals in water. The project received funding from the Department of Biotechnology (DBT), India. The sensor uses a copper-based metal-organic framework (MOF) called copper-tetra carboxyphenyl porphyrin (Cu-TCPP) for efficient detection. It can detect lead, cadmium, and mercury even in trace amounts. The MOF structure allows metal ion replacement without collapsing, improving detection capability. Tests on tap and lake water confirmed its accuracy. The sensor performs as well as or better than DNA-based sensors, with simpler design and efficiency.

Notes:
CSIR-National Botanical Research Institute (NBRI) in Lucknow developed the world’s first genetically modified (GM) cotton fully resistant to Pink Bollworm (PBW). GM cotton was introduced in India in 2002, with Bollgard 1 and Bollgard 2 developed with Monsanto, but they failed to fully protect against PBW. CSIR-NBRI is a leading research institute focused on botanical research and conservation. Pink Bollworm (PBW), also called gulabi sundhi, damages cotton by burrowing into bolls. PBW spreads through air and crop residue, affecting future harvests.

Notes:
Scientists discovered new species on the seafloor exposed by the A-84 iceberg, which broke off the George VI Ice Shelf on January 13, 2025. An ice shelf is a floating mass of ice, fed by glaciers from land, extending over the sea. Antarctica and Greenland ice sheets hold two-thirds of Earth’s freshwater, with the West Antarctic Ice Sheet being one of the largest. When ice sheets gain mass, sea levels fall, and when they lose mass, sea levels rise. The discovery was part of the Challenger 150, a UNESCO-endorsed global deep-sea research initiative. Remotely Operated Vehicle (ROV) SuBastian explored the seabed 1,300 meters deep.

Notes:
The Euclid Space Telescope captured images of galaxies in different shapes. Named after ancient Greek mathematician Euclid, it is part of ESA’s Cosmic Vision Programme. It was launched by SpaceX Falcon 9. Its operational lifespan is at least 6 years. It is positioned 1.5 million km above Earth at the Lagrange Point 2 (L2). It is 4.7 meters tall and 3.7 meters in diameter, with image quality four times sharper than ground-based telescopes. Its mission includes studying dark energy, dark matter, and the universe’s large-scale structure in 3D.

Notes:
African Swine Fever (ASF) has resurged in Mizoram, causing 41 more pig deaths, raising the total toll to 503 since March 20. ASF first emerged in Mizoram in Lungsen village, Lunglei, on March 21, 2021, and has since become endemic. The causative agent of African Swine Fever (ASF) is the African Swine Fever Virus (ASFV). ASF is a highly contagious and fatal viral disease affecting domestic and wild pigs but poses no risk to humans. The virus can spread through contaminated clothing, equipment, or vehicles, threatening pig populations. There is no treatment or vaccine, making prevention and strict biosecurity measures the only effective control methods.
