Science & Technology Current Affairs MCQs

Notes:
Waaree Energies will set up India’s largest lithium-ion battery gigafactory at Rambilli, Anakapalli district, Andhra Pradesh. Total investment is ₹8,175 crore for a greenfield project. The plant will have 16 Gigawatt-hour (GWh) capacity. It will cover full battery value chain: cell manufacturing, battery packs and Battery Energy Storage Systems (BESS). It received in-principle approval from State Investment Promotion Board. The project supports clean-energy goals of Andhra Pradesh.

Notes:
Recently, the Meghalaya government issued an advisory after a meningococcal infection scare, urging people to avoid crowded places and follow health protocols. Meningococcal infection is a severe and rapidly progressing disease caused by the bacterium Neisseria meningitidis. It can lead to meningitis, which is inflammation of the meninges covering the brain and spinal cord, or meningococcemia, which is blood poisoning. It spreads through respiratory and throat secretions like saliva during close or prolonged contact. It is less contagious than common cold or flu infections.

Notes:
Researchers detected a lightning-like “whistler” radio signal in the Martian ionosphere, first evidence of such electromagnetic activity on Mars. Detection was made using data from Mars Atmosphere and Volatile EvolutioN (MAVEN) mission. The MAVEN (Mars Atmosphere and Volatile EvolutioN) mission was launched by the National Aeronautics and Space Administration (NASA). It is the first spacecraft dedicated to studying the Martian upper atmosphere to understand how the planet lost its atmosphere and water over time.

Notes:
Astronomers using the MeerKAT telescope in South Africa discovered the brightest and most distant megamaser. MeerKAT is a precursor to the Square Kilometre Array (SKA) telescope located in South Africa. It is designed for advanced radio astronomy. A megamaser is a giant beam of electromagnetic radiation produced when two galaxies collide violently. During such cosmic mergers, large gas clouds compress, exciting hydroxyl (OH) molecules, which emit high-energy microwaves.

Notes:
Proba-3 recently made news after European Space Agency lost contact with one of its two spacecraft. It is European Space Agency’s first mission focused on precision formation flying, where two satellites operate in extremely accurate coordination. The mission aims to create an artificial solar eclipse to study the Sun’s outer atmosphere (corona). This helps scientists observe the faint solar corona, which is normally hidden by the Sun’s intense brightness. The mission includes two small satellites: a Coronagraph spacecraft and an Occulter spacecraft shaped like the solar disc.

Notes:
The Centre for Development of Telematics, an autonomous telecom research and development body under the Department of Telecommunications, organised a Demo Day for 18 startups under the Samarth Incubation Programme (Cohort-II) at NBCC Convention Hall. The Samarth incubation programme, launched in March 2025, by Centre for Development of Telematics. It aims to support startups in the telecom and Information and Communication Technology (ICT) sectors and strengthen India’s digital innovation ecosystem.

Notes:
Agnikul Cosmos has achieved a major milestone by successfully test-firing the Agnite Engine, marking progress in India’s private space sector. Agnite is the world’s largest single-piece 3D-printed booster engine, showcasing advanced additive manufacturing technology. It is part of a family of engines including Agnite and Agnilet, which are 3D-printed semi-cryogenic engines developed by Agnikul. These engines are specifically built to power the booster stage of Agnikul’s Agnibaan launch vehicle.

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:
Hib (Haemophilus influenzae type b) disease is resurging in the United States due to declining childhood vaccination rates. It is caused by the bacterium Haemophilus influenzae type b infection and mainly affects children under 5 years. It can cause mild infections (ear infections, bronchitis) and severe diseases like meningitis and bloodstream infections. Despite its name, it does not cause influenza (flu). Transmission occurs through respiratory droplets (coughing, sneezing) and close contact. Symptoms vary depending on the infected body part; severe cases may lead to death or long-term complications.

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.
