Science & Technology Current Affairs MCQs

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 Prime Minister praised Indian space startup Digantara for the success of its Mission SCOT. SCOT (Space Camera for Object Tracking) is Digantara’s first mission for space surveillance and one of the world’s first commercial Space Situational Awareness (SSA) satellites. It was launched aboard SpaceX’s Transporter-12 mission and deployed in a sun-synchronous orbit. SCOT is designed to track Resident Space Objects (RSOs) as small as 5 cm in Low Earth Orbit (LEO) with high accuracy and revisit rates. It addresses gaps in existing systems limited by fields of view, weather, and geography.

Notes:
IIT-Madras has launched a zero-waste bioplastics initiative supported by the Ministry of Chemicals and Fertilisers. The initiative aims to develop biodegradable, microplastic-free, and cost-effective alternatives to conventional plastics. Third-generation bioplastics use agricultural residues, algae, and waste materials, avoiding food security concerns linked to earlier food-based bioplastics. These bioplastics fully decompose, leaving no harmful particles behind, reducing the environmental footprint. The centre is also exploring bioplastics for food packaging and medical textiles, including biodegradable implants from agricultural waste.

Notes:
Niger has become the first African country to eliminate onchocerciasis, or river blindness. It joins Colombia, Ecuador, Mexico, and Guatemala as WHO-verified onchocerciasis-free nations. Onchocerciasis is a parasitic disease affecting the eyes and skin, causing severe disability. It leads to disfiguring skin conditions, vision loss, and permanent blindness in severe cases. The disease has severely impacted livelihoods for decades. Over 99% of cases still occur in 31 African countries.

Notes:
Ranikhet disease has caused the death of 1.5 lakh chickens in Andhra Pradesh. It is a contagious viral disease affecting poultry like chickens, turkeys, and ducks. It is caused by Newcastle disease virus (NDV) or avian paramyxovirus-1 (APMV-1). The disease attacks birds’ respiratory, nervous, and digestive systems. It leads to production drops and fertility issues in birds. Morbidity is high, and mortality ranges from 50 to 100%. It is a minor zoonosis, potentially causing mild conjunctivitis in humans, but usually self-limiting.

Notes:
India has signed an agreement with Russia to acquire the Klub-S missile system for its submarine fleet. It is developed by Russia defence company NPO Novator. The Klub missile, also known as Kalibr, entered service in 1994. The Klub-S missile has a 400 kg warhead and can strike targets up to 300 km away, including surface ships, submarines, and land targets. It includes a fire control system, vertical launcher unit, and ammunition. It is known for its effectiveness in combat, it can reach supersonic speeds in the terminal phase, making interception difficult. The missile cruises at 10-15 meters, minimizing enemy defense response time.

Notes:
IIT Guwahati researchers have developed a water-repellent, conductive textile that converts electricity and sunlight into heat to keep wearers warm in extreme cold. It helps prevent blood clotting, breathing issues, and weak immunity caused by prolonged cold exposure. The textile is made by spraying ultra-thin silver nanowires onto cotton fabric, making it lightweight, flexible, and durable. A lotus leaf-inspired coating makes it waterproof, stain-resistant, and oxidation-proof, ensuring long-lasting performance. It maintains 40°C-60°C for 10+ hours using a battery or solar energy.

Notes:
IIIT-Delhi researchers developed AI-powered tools for tracking antibiotic resistance in real time. The project is a collaboration between IIIT-Delhi, CHRI-PATH, Tata 1mg, and ICMR scientists. The AI tool, AMRSense, analyzes hospital data to provide early insights on antimicrobial resistance. It operates at global, national, and hospital levels to aid quick action. The research established links between antibiotic resistance patterns in community and hospital infections.

Notes:
Clinical neuroscientists have treated spinal muscular atrophy (SMA) in a baby before birth. SMA is a genetic disorder affecting motor neurons, causing progressive muscle weakness. It has five types (0-4), classified by age of onset and severity. Symptoms include muscle weakness, especially near the body’s center, but do not affect involuntary muscles like the heart. It is caused by SMN1 gene mutations, leading to motor neuron loss. It affects 1 in 10,000 births and is a leading genetic cause of infant deaths.

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.
