Science & Technology Current Affairs MCQs

Notes:
Hyderabad-based biotech company, Biovet has received Central Drug Standards Control Organization (CDSCO) approval for its Lumpy Skin Disease (LSD) vaccine, Biolumpivaxin, for dairy cattle and buffaloes. Lumpy Skin Disease (LSD) is an infectious viral disease caused by the lumpy skin disease virus (LSDV), part of the poxviridae family. LSD primarily affects cattle and, to a lesser extent, buffalo, with higher morbidity in cattle. The disease leads to reduced milk production, sterility in bulls, and damage to hides. It spreads through blood-feeding insects and contaminated water or fodder. LSD is not zoonotic, so humans cannot get infected by the virus.

Notes:
The European Space Agency’s (ESA) Euclid space telescope discovered a rare Einstein ring around the galaxy NGC 6505. NGC 6505 is an elliptical galaxy located 590 million light-years away in the Draco constellation. The discovery is considered extraordinary, especially for Euclid’s early data. An Einstein ring is a circular light ring formed due to gravitational lensing by a galaxy, dark matter, or a galaxy cluster.

Notes:
Uganda and WHO confirmed an outbreak of Sudan Virus Disease (SVD). It is a viral hemorrhagic fever, related to Ebola, caused by the Sudan virus (SUDV). It was first identified in Sudan in 1976. It exists in animal reservoirs in the region. It has a high fatality rate and spreads through direct contact with bodily fluids or contaminated surfaces. Symptoms start with fever, fatigue, and sore throat, followed by vomiting, diarrhea, rash, and bleeding. There are no approved treatments or vaccines, but early supportive care improves survival chances.

Notes:
China has approved the construction of a deep-sea research facility in the South China Sea. This facility, also known as a “deep-sea space station”, is expected to be operational by 2030. The facility will be located 2,000 meters (6,560 feet) below the ocean’s surface.  It will be one of the deepest and most technologically advanced underwater installations ever attempted.  The facility will study cold seep ecosystems, which are methane-rich hydrothermal vents.  It will accommodate six scientists for missions lasting up to a month.

Notes:
NASA is preparing for the PUNCH mission, a first-of-its-kind solar mission to study the solar atmosphere. PUNCH (Polarimetry to Unify the Corona and Heliosphere) will be launched by SpaceX. It consists of four suitcase-sized satellites, each weighing 64 kg, placed in Low Earth Orbit (LEO). The mission will use three Wide Field Imagers and one Narrow Field Imager to capture polarised and unpolarised images. It will provide 3D measurements of the corona and solar wind using light polarisation. The data will help improve space weather predictions and protect space missions. The mission is expected to last two years.

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:
Scientists in Australia have discovered the world’s oldest known meteorite impact crater in northwestern Australia, estimated to be 3.47 billion years old. The North Pole Crater is over 1 billion years older than any previous impact site. It was likely formed by a meteorite striking Earth at 36,000 km/h, creating a site 100 km wide. The collision may have sent debris as far as South Africa. This discovery challenges prior beliefs about Earth’s early history and suggests such impacts may have contributed to the origins of life.

Notes:
Researchers have successfully turned light into a “supersolid” for the first time. Supersolids are a unique state of matter defined by quantum mechanics. They form an orderly crystalline solid but flow like a liquid without viscosity. Unlike normal solids, supersolids can change direction and density based on particle interactions. They maintain an organized lattice structure while exhibiting fluid-like movement. The discovery could enhance qubit stability in quantum computing and advance optical circuits, photonic devices, and fundamental physics research.

Notes:
NASA reported that global sea levels rose faster than expected in 2024. The rise reached 0.59 cm per year, exceeding the expected 0.43 cm. The main causes are ocean warming, which leads to expansion, and meltwater from glaciers and ice sheets. In 2024, thermal expansion caused two-thirds of the rise, shifting from previous years when melting ice was the dominant factor. 2024 was the warmest year on record, with ocean levels at their highest in three decades. Since satellite monitoring began in 1993, global sea levels have risen by 10 cm, with the rate more than doubling.

Notes:
V Narayanan, Chairman of ISRO, inaugurated the ‘Shri S. Ramakrishnan Centre of Excellence in Fluid and Thermal Science Research’ at IIT Madras on March 17, 2025. The centre supports ‘Atmanirbhar Bharat’ by advancing space technologies and attracting global research talent. It focuses on spacecraft and launch vehicle thermal management, crucial for India’s space missions. S Ramakrishnan, an IIT Madras alumnus, contributed significantly to PSLV and GSLV MK3 development. ISRO scientists will collaborate with IIT Madras to develop advanced cooling systems for spacecraft. The research will support future lunar, Mars, and deep-space missions.
