Science & Technology Current Affairs MCQs

Notes:
BEML Ltd launched the BD475-2 Dozer, India’s largest and most advanced crawler dozer, showcasing the country’s engineering excellence and self-reliance. Powered by a 950 HP engine, it was developed entirely in-house at BEML’s Kolar Gold Fields facility. The BD475-2 Dozer enhances fuel efficiency and performance, supporting mining operations. This launch highlights India’s technological growth, aligning with the Aatma Nirbhar Bharat vision for sustainable development.

Notes:
IIT Bombay developed a shockwave-based, needle-free syringe for painless drug delivery, reducing skin damage and infection risks. The syringe uses high-energy shockwaves to create a microjet of liquid drug that penetrates the skin without needles. It consists of a driver, driven section, and drug holder, powered by pressurized nitrogen gas. Effective in tests on rats, it showed deeper tissue penetration with minimal skin damage. The device supports over 1,000 uses, needing only nozzle replacements, making it cost-effective. It could accelerate immunization drives like Mission Indradhanush and lower risks of needle-related infections.

Notes:
Union Minister Dr. Jitendra Singh announced the indigenously developed “Paracetamol” by Council of Scientific and Industrial Research (CSIR) during the 40th Foundation Day of the Department of Scientific and Industrial Research. CSIR’s new technology aims to produce paracetamol domestically, reducing dependence on imported raw materials. Karnataka-based Satya Deeptha Pharmaceuticals Ltd will manufacture affordable paracetamol using this breakthrough. The initiative supports India’s self-reliance in pharmaceutical production and aligns with PM Modi’s “Atmanirbhar Bharat” vision. The development addresses the current import dependency for key raw materials used in paracetamol production.

Notes:
Germany recently faced its first foot-and-mouth disease (FMD) outbreak in nearly 40 years, affecting water buffalo near Berlin. Foot-and-Mouth Disease (FMD) is a highly contagious viral disease impacting livestock like cattle, swine, sheep, and goats but not horses, dogs, or cats. The disease severely affects livestock production and disrupts trade in animals and animal products. It circulates in 77% of global livestock, mainly in Africa, the Middle East, Asia, and parts of South America. FMD is not a human health risk and is transmitted through excretions, secretions, and aerosolized virus from infected animals.

Notes:
The Ministry of Electronics & Information Technology (MeitY) and Data Security Council of India (DSCI) launched the second edition of the Cyber Security Grand Challenge (CSGC 2.0). The prize pool has been increased to Rs. 6.85 crores from Rs. 3.2 crores. Innovators, startups, and entrepreneurs are invited to address six key cybersecurity challenges, including API Security, Data Security, and AI for Threat Detection. Intellectual property rights for solutions developed will stay with startups. The competition has four stages, with winners receiving Rs. 25 lakh, and the overall winner getting Rs. 1 crore. The initiative supports Digital India and Atmanirbhar Bharat.

Notes:
The Union Cabinet approved a Third Launch Pad (TLP) at Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh. TLP will support ISRO’s Next Generation Launch Vehicles (NGLV) and human spaceflight missions. It will serve as a backup for the Second Launch Pad (SLP) and support LVM3 vehicles with advanced stages. The project costs ₹3984.86 crore and is expected to be completed in four years. TLP will boost launch frequencies, enabling India’s space goals, including the Bharatiya Antariksha Station by 2035 and crewed lunar landing by 2040. It enhances India’s capacity for heavier and advanced launch vehicles.

Notes:
The Pralay missile, India’s first tactical quasi-ballistic missile, will be showcased in the Republic Day parade. It is a short-range surface-to-surface ballistic missile with a range of 150-500 km, developed to meet the Army’s tactical needs. Pralay can carry a 350-700 kg conventional warhead and strike enemy positions with high accuracy. It was developed by DRDO.

Notes:
IIT-Madras researchers have extracted silicon carbide (SiC) from simulated moon soil, aiding future lunar habitat construction. Silicon carbide (SiC), also called carborundum, is a synthetic crystalline compound of silicon and carbon. It is extremely hard, has high thermal conductivity, and offers excellent resistance to wear, oxidation, and chemical reactions.

Notes:
South Africa’s MeerKAT telescope discovered a new giant radio galaxy (GRG) named ‘Inkathazo,’ meaning ‘trouble’ in Xhosa and Zulu. The galaxy spans 3.3 million light-years, 32 times the size of the Milky Way, and is 1.44 billion light-years from Earth. GRGs are massive structures that emit jets of hot plasma powered by supermassive black holes. These jets glow at radio frequencies and stretch millions of light-years into space. Once considered rare, GRGs are now being discovered frequently due to advanced radio telescopes like MeerKAT in South Africa’s Northern Cape.

Notes:
NASA is set to launch SPHEREx, a revolutionary space telescope, to explore the universe’s origins. It will cost $488 million, far less than the $10 billion James Webb Space Telescope (JWST). Unlike JWST, which zooms in on deep-space objects, SPHEREx will survey the entire sky in 102 infrared colors. The telescope will take 600 images daily, completing four full sky scans in 27 months. SPHEREx will map 450 million galaxies, revealing how the universe evolved after the Big Bang. It will also study 100 million Milky Way stars, tracing life’s building blocks in space.
