Science & Technology Current Affairs MCQs

Notes:
Health officials in Maryland, United States recently reported an increase in mumps cases and issued a health alert. Mumps is a contagious viral disease caused by the mumps virus, which belongs to the paramyxovirus group. The disease mainly causes painful swelling of the parotid salivary glands (parotitis) near the ears and jaw. Humans are the only host, and the virus spreads through respiratory droplets from sneezing, coughing, or contact with infected saliva. There is no specific treatment, and medicines mainly relieve symptoms.

Notes:
Van Allen Probes A satellite, weighing about 600 kg, is re-entering Earth’s atmosphere, raising discussion about possible ground risks. The Van Allen Probes mission by NASA was the first mission to study Earth’s radiation belts using two spacecraft together. The twin spacecraft Van Allen Probe A and Van Allen Probe B were launched on 30 August 2012 to explore Earth’s radiation environment. They studied the Van Allen Radiation Belts, which are rings of energetic charged particles trapped by Earth’s magnetic field. These belts are named after space scientist James Van Allen, who discovered them in 1958.

Notes:
Researchers recently identified an unusual iron sulfate ferric hydroxysulfate in layered deposits near Valles Marineris using laboratory experiments and orbital data. Valles Marineris, also called Mariner Valley, is a vast system of interconnected canyons on Mars. It was discovered during the Mariner 9 mission in 1971. It is one of the largest canyon systems in the Solar System. Some canyon walls are fault scarps formed due to crustal movement linked to Tharsis Rise. Erosion also shaped the canyon, seen in deep gullies along the walls.

Notes:
Researchers at the U.S. National Institutes of Health discovered that cholesterol present in the membrane around the cell nucleus plays a role in promoting the spread of melanoma, a type of skin cancer. Melanoma originates in melanocytes, which are specialized cells responsible for producing melanin, the pigment that gives color to the skin. This type of cancer typically develops on areas of the skin that are frequently exposed to the sun, such as the arms, back, face, and legs, although it can occasionally appear inside the body, including in the nose or throat. Ultraviolet (UV) light exposure, whether from sunlight or artificial sources like tanning lamps and beds, is the main cause of most melanomas, although other factors may also contribute.

Notes:
Indian Council of Agricultural Research–Indian Veterinary Research Institute produced Sahiwal calves using OPU–IVF–ET (Ovum Pick-Up–In Vitro Fertilization–Embryo Transfer). Sahiwal cattle is one of the best milk-producing indigenous breeds of India. It originates from Sahiwal region in Montgomery district of Punjab in Pakistan. It is also known as Lambi Bar, Lola, Montgomery, Multani and Teli. The cows are brownish-red in colour with shades from mahogany to greyish red, while bulls have darker extremities.

Notes:
Chief Minister N Chandrababu Naidu unveiled a plan to develop Amaravati as a global hub for quantum computing.
The initiative, Amaravati Quantum Valley (AQV), aims to place Andhra Pradesh among the top 5 global quantum hubs by 2030, leveraging the National Quantum Mission. The first quantum computer is set to be launched on April 14, marking a major milestone. The ecosystem will include hardware manufacturing, algorithm development, research, and innovation labs, supported by 8 dedicated research towers. The state plans to develop core technologies locally (cryogenics, photonics, advanced electronics) to reduce import dependence and achieve end-to-end capabilities.

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:
The Pentagon’s Project Maven AI program was launched by the United States in 2017. The program was launched by the United States in 2017. It uses machine learning and computer vision to automatically detect objects, movements, and patterns, reducing the need for manual analysis. The programme helps in real-time identification and tracking of targets, improving the speed and accuracy of military operations.

Notes:
India’s first indigenous Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu, has successfully attained criticality. A Fast Breeder Reactor (FBR) produces more fissile fuel than it consumes using fast neutrons. Criticality is the stage where a self-sustaining nuclear chain reaction is achieved. The 500 Megawatt Electric (MWe) PFBR is developed by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI). It uses Uranium-Plutonium Mixed Oxide fuel and liquid sodium as coolant. It supports India’s three-stage nuclear programme, enabling Thorium-232 to Uranium-233 conversion for long-term energy security.

Notes:
Andhra Pradesh has launched India’s first quantum test facilities under the Amaravati Quantum Valley initiative on the occasion of World Quantum Day (April 14). The facilities include two Quantum Reference Facilities at SRM University, Amaravati and Medha Towers, Gannavaram, creating India’s first quantum test and certification ecosystem. The systems operate at extremely low temperatures (near −273°C) and support advanced quantum research and innovation. The initiative promotes collaboration among academia, startups, and industry, with support from institutions like Tata Institute of Fundamental Research (TIFR), Indian Institute of Science (IISc), and Defence Research and Development Organisation (DRDO).
