Science & Technology Current Affairs MCQs

Notes:
NASA has unveiled a new map of the ocean floor using data from the SWOT Satellite. The SWOT Satellite was developed by NASA in collaboration with Centre National d’Etudes Spatiales (CNES), France. Its main objective is to conduct the first global survey of Earth’s surface water and observe detailed ocean surface topography. The satellite measures how water bodies change over time to track variations in lakes, rivers, and oceans. It maps the ocean floor indirectly by detecting tiny changes in water height, which reveal the features beneath the ocean surface.

Notes:
Shigellosis is an infectious disease caused by the bacterium Shigella, and a recent outbreak has been reported in Kerala. It is a highly contagious disease that causes acute diarrhoea and is one of the leading bacterial causes of diarrhoeal illness globally. The infection can affect people of all age groups, but children below five years are the most vulnerable. Humans act as the only natural reservoir of the Shigella bacteria, which helps in its rapid spread. The illness is usually self-limiting in mild cases, but severe infections may require treatment with antibiotics. The disease can become more serious in young children, elderly individuals, malnourished persons, and those with weak immune systems.

Notes:
Indian Space Research Organisation conducts the YUva VIgyani KAryakram (YUVIKA) to promote scientific temper among school students. The YUVIKA (YUva VIgyani KAryakram) programme is an initiative of the Indian Space Research Organisation (ISRO). The programme provides foundational knowledge in space technology, space science, and space applications, with special focus on students from rural areas. Its objective is to create awareness about emerging trends in science and encourage students to pursue Science, Technology, Engineering and Mathematics (STEM) careers.

Notes:
As part of Gaganyaan mission, the Indian Space Research Organisation is conducting Mission MITRA (Mapping of Interoperable Traits and Response Assessment) in Leh from April 2 to April 9, 2026. Mission MITRA is a first-of-its-kind team behavioral study, developed jointly by ISRO and the Institute of Aerospace Medicine, aimed at evaluating crew safety and performance in human spaceflight. The study focuses on team communication, adaptability to stress, psychological resilience, and mutual support, which are critical for mission success. Leh’s high-altitude environment (approx 3,500 metres), hypoxia, low temperature, and isolation serve as a natural analog for spaceflight operations.

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:
The Bombay High Court was informed that the Maharashtra government has not yet framed a policy to address Subacute Sclerosing Panencephalitis (SSPE), a rare but fatal neurological disease. Subacute Sclerosing Panencephalitis (SSPE), also known as Dawson disease, is a progressive and disabling brain disorder caused by a persistent infection of the measles (rubeola) virus. The disease typically develops several years after a person has recovered from measles, due to an abnormal immune response or mutated virus. It is a rare condition occurring in about one per 50,000 measles cases and mainly affects children and adolescents, with males being more vulnerable.

Notes:
Herbalife India and Indian Institute of Technology Madras signed a Memorandum of Understanding on 17 April 2026 to establish a new research facility. The initiative sets up India’s first Centre of Excellence on Plant Cell Fermentation Technology at IIT Madras Research Park, Chennai. The centre aims to promote research, innovation, and entrepreneurship in sustainable production of herbal biomass and phytochemicals. It focuses on plant cell fermentation for scalable and eco-friendly production of compounds for health and wellness.

Notes:
Recently, the Curiosity rover of NASA detected a mix of organic molecules on Mars, strengthening evidence about the planet’s past habitability. The Curiosity rover mission was launched by the National Aeronautics and Space Administration (NASA). It was launched on November 26, 2011, the rover is a key component of the Mars Science Laboratory (MSL) mission to study Gale Crater on Mars. Its objectives include studying whether life ever existed, understanding Mars’ climate and geology, and preparing for future human missions.

Notes:
Diphtheria is re-emerging in parts of Australia despite being largely controlled earlier, raising public health concerns. It is a highly contagious bacterial infection caused by Corynebacterium diphtheriae, which produces a harmful toxin. The disease mainly affects the upper respiratory tract, especially the throat, nose, and tonsils, and sometimes the skin. It spreads through respiratory droplets or contact with infected wounds, and even asymptomatic individuals can transmit it.

Notes:
Researchers from Central University of Rajasthan discovered a new cyanobacterium species named Pushkarmema curajae from Pushkar Lake, Rajasthan. The genus and species names honor Pushkar Lake and the university’s contribution to research. P. curajae has potential applications in pharmaceuticals, biofertilizers, and nutrient-rich supplements that enhance immunity and health. Cyanobacteria are photosynthetic, microscopic organisms found in aquatic environments worldwide.
