Science & Technology Current Affairs MCQs

Notes:
India’s indigenous surgical robotic system, SSI Mantra, conducted two successful robotic cardiac telesurgeries. The first procedure, Telerobotic-assisted Internal Mammary Artery Harvesting, was completed in 58 minutes with 35-40 milliseconds latency. SSI Mantra successfully performed a robotic beating heart Totally Endoscopic Coronary Artery Bypass (TECAB), one of the most complex cardiac surgeries. SSI Mantra is the only robotic system globally approved for telesurgery and tele-proctoring, revolutionizing rural healthcare access in India. It recently received approval from the Central Drugs Standard Control Organisation (CDSCO) under the Drugs & Cosmetics Act, 1940.

Notes:
Bangalore Medical College and Research Institute (BMCRI) has been selected by Indian Council of Medical Research (ICMR) to host South India’s first Infectious Disease Research and Diagnostic Laboratory (IRDL). The lab will focus on research and diagnostics for bacterial, fungal, and parasitic infections, enabling quicker and more accurate disease management. This is part of a nationwide initiative to enhance medical research infrastructure in India. The lab will also study antibiotic resistance, fungal infections, and tropical diseases.

Notes:
Hyderabad is seeing an increase in scarlet fever cases among children aged 5 to 15, along with other viral fevers during winter. Scarlet fever, also known as scarlatina, is a bacterial infection that causes a red rash, sore throat, and fever. It’s caused by group A streptococcus bacteria, also known as strep throat bacteria. Symptoms include a bright red, sunburn-like rash, sore throat, high fever, and peeling skin on hands and feet. Antibiotics can fully treat scarlet fever, but patients must complete the entire course. If untreated, scarlet fever can cause serious complications like kidney damage, heart issues, and pneumonia.

Notes:
Centre for Development of Telematics (C-DOT) and IIT Delhi signed an agreement to develop THz communication front ends for 6G under the Telecom Technology Development Fund (TTDF). TTDF is established under the Universal Services Obligation Fund (USOF), now called Digital Bharat Nidhi, by the Department of Telecom. The fund supports research, design, prototyping, testing, and manufacturing in telecommunications. It aims to foster rural-specific communication technologies, promote technology ownership, and encourage indigenous manufacturing. TTDF seeks to boost exports, reduce imports, enhance co-innovation, and support Intellectual Property creation in the telecom sector.

Notes:
Lunar landers by U.S. and Japanese companies launched together on a SpaceX Falcon 9 rocket, showcasing private sector involvement in space exploration. The mission includes two lunar spacecraft: Blue Ghost by Firefly Aerospace (U.S.) and Resilience by ispace-Europe (Luxembourg, Japan). Blue Ghost carries 10 NASA instruments to study Earth’s magnetosphere, lunar dust, and Moon’s thermal properties while testing advanced navigation and computing. Resilience includes the Tenacious micro rover with a high-definition camera and regolith-scooping technology, exploring Mare Frigoris on the Moon’s far north. The mission promotes technological advances, global collaboration, and cost-effective strategies for future lunar sustainability under NASA’s Artemis program.

Notes:
Venus, Saturn, Jupiter, and Mars formed a rare arc in the night sky, called a ‘planet parade.’ A planet parade occurs when multiple planets are visible in the night sky simultaneously. This phenomenon, also known as a conjunction, makes planets appear close together or even touching, though it is a perspective illusion. Planets have unique motions and move at different rates, making simultaneous visibility uncommon. Such alignments involving four or more planets are rare and do not happen annually, as highlighted by NASA.

Notes:
Swiss researchers have developed a gene editing technique to potentially treat Stargardt disease, also known as Stargardt macular degeneration. This rare genetic eye condition causes progressive vision loss in children and young adults, usually bilateral, involving both eyes. The disease is characterized by excessive lipofuscin buildup over the macula, responsible for clear central vision. The disease is more common in males and affects 1 in 8000 to 10,000 populations. Currently, there is no cure for the disease.

Notes:
ISRO successfully launched the navigation satellite NVS-02 on January 29 aboard GSLV-F15 from Satish Dhawan Space Centre (SDSC), Sriharikota. This was ISRO’s historic 100th launch, marking a major milestone. GSLV-F15 used an indigenous cryogenic stage to place the satellite in a Geosynchronous Transfer Orbit (GTO). This was the 17th flight of the GSLV series and the 11th using ISRO’s cryogenic engine. NVS-02 will replace IRNSS-1E and enhance India’s navigation capabilities.

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:
The Department of Biotechnology launched the GARBH-INi-DRISHTI data repository at Translational Health Science and Technology Institute (THSTI). It provides clinical data, images, and biospecimens from over 12,000 pregnant women, newborns, and postpartum mothers. It is one of South Asia’s largest maternal and child health databases. The repository will help researchers worldwide improve maternal and neonatal health outcomes. THSTI also inaugurated a Ferret Research Facility with high biosafety standards. The facility will support vaccine development, therapeutic testing, and research on emerging infectious diseases.
