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:
The first astronomical observatory in Eastern India has been inaugurated in Garpanchkot Hills, Purulia, by the Satyendra Nath Bose National Centre for Basic Sciences (SNBNCBS). This is the sixth such observatory in India and is named after Satyendra Nath Bose. The observatory, located 600 meters above sea level at approximately 86° E longitude, fills a key gap in astronomical observations. It aims to aid scientific observations, student training, and foster national and international research collaborations. The observatory is strategically placed to observe transient astronomical phenomena. Satyendra Nath Bose Centre has partnered with Sidhu Kanu Birsa University for its operation.

Notes:
The U.S. military has relocated Typhon missile launchers within the Philippines to improve mobility and survivability amid tensions with China and Russia. Typhon, or the Mid-Range Capability (MRC), is a mobile, surface-to-surface missile system developed by Lockheed Martin, United States. It features a modular design and can fire multiple missile types, including the SM-6 (500 km range) and Tomahawk cruise missiles (2,500 km range). The SM-6 strikes air and surface targets, while the Tomahawk is effective for land-attack and anti-ship missions. A full Typhon system includes four launchers, a command post, and support vehicles on trailers.

Notes:
The International Solar Conference celebrated the 125th anniversary of the Kodaikanal Solar Observatory. The observatory, established in 1899, is currently owned and operated by the Indian Institute of Astrophysics. It is located in Kodaikanal, Tamil Nadu, in the Palani range of hills, chosen for its proximity to the equator and dust-free high-altitude setting. The observatory’s objective is to gather data on how the sun affects Earth’s atmosphere and to better understand monsoon patterns.

Notes:
Georgia has been certified malaria-free by the World Health Organization. It is located at the intersection of Eastern Europe and West Asia, in the Transcaucasia region. Malaria is a life-threatening fever caused by Plasmodium parasites spread by infected female Anopheles mosquitoes. It is primarily found in tropical countries and is not contagious. The disease cannot spread from person to person; transmission occurs through mosquito bites.

Notes:
Pune district in Maharashtra is the worst-hit region for Zika virus in India, with 125 out of 151 cases reported in 2024. Maharashtra recorded 140 cases, followed by Karnataka (10) and Gujarat (1). The Zika virus is spread by Aedes mosquitoes, which also transmit dengue and yellow fever. It can cause microcephaly in newborns and Guillain-Barré syndrome in adults. The virus was discovered in the Zika Forest, Uganda (1947), and the first human case was reported in 1952. A major Zika outbreak occurred in Brazil (2015).

Notes:
Japan successfully launched the Michibiki 6 satellite on the new H3 rocket, aiming to improve its navigation system. The launch occurred at the Tanegashima Space Center, and the satellite separated successfully 29 minutes after liftoff. Michibiki 6 will be the fifth satellite in Japan’s quasi-zenith satellite system (QZSS). The system supplements US GPS and improves positioning for various devices. Japan plans to expand to seven satellites by 2026 and an 11-satellite network by the late 2030s. The launch was the fourth successful flight for the H3 rocket system.

Notes:
The Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru, India developed the high-entropy alloy (HEA) catalyst for hydrogen production. CeNS is an autonomous institute of the Department of Science and Technology (DST). The catalyst is made of platinum, palladium, cobalt, nickel, and manganese (PtPdCoNiMn). The catalyst was prepared using two methods: electrodeposition and solvothermal processes.  The catalyst is more efficient than pure platinum and uses seven times less platinum than commercial catalysts.  The catalyst is stable and efficient for over 100 hours in alkaline seawater.

Notes:
Brucellosis, a bacterial disease, caused the death of an 8-year-old in Kerala. It is caused by Brucella bacteria, mainly infecting cattle, goats, sheep, swine, and dogs. Humans get infected through direct contact with animals, consuming contaminated animal products, or inhaling airborne agents. Unpasteurised milk and cheese from infected animals are the most common sources. Symptoms include fever, weakness, weight loss, and discomfort, often mild and undiagnosed.
