Science & Technology Current Affairs MCQs

Notes:
The Department of Health and Human Services recently confirmed the first human case of the flesh-eating parasite, the New World screwworm, in the United States. New World screwworm is a blue-grey blowfly usually found in South America and the Caribbean. Its larvae burrow screwlike into living tissue, causing dangerous infestations. Female flies lay eggs in open wounds or cavities, with up to 3,000 eggs in their lifespan. Symptoms include non-healing wounds, bleeding, foul smell, and sensation of movement. Infestation is extremely painful and can be fatal if untreated.

Notes:
Prime Minister of India welcomed the agreement between Indian Space Research Organisation (ISRO) and Japan Aerospace Exploration Agency (JAXA) for the Chandrayaan-5 mission under the Lunar Polar Exploration (LUPEX) programme. LUPEX is jointly developed by ISRO and JAXA to explore the Moon’s southern polar region. The mission aims to investigate the presence of water and other elements, potentially as surface ice, and demonstrate innovative surface exploration technologies. It features a lander developed by ISRO and a rover developed by JAXA. The rover will autonomously search for water-rich areas, drill, sample soil, and analyze it with onboard instruments.

Notes:
Russia has launched EnteroMix, a new mRNA-based cancer vaccine, reported to show 100 percent efficacy in early trials. It was developed by the National Medical Research Radiology Centre (NMRRC) and Engelhardt Institute of Molecular Biology under the Russian Academy of Sciences. The launch took place at the St Petersburg International Economic Forum (SPIEF 2025) and shared globally via Sputnik news service. The vaccine targets colorectal cancer first, with versions in development for glioblastoma and melanoma. EnteroMix uses four harmless viruses to attack cancer cells and boost immune defence. Russian Federal Medical and Biological Agency (FMBA) confirmed its safety for repeated use and personalised RNA-based tailoring.

Notes:
Turakapalem village in Guntur, Andhra Pradesh, has seen 29 deaths due to Melioidosis. It is caused by the Gram-negative bacterium Burkholderia pseudomallei found in soil and water. The government has declared a public health emergency in the area. The disease is seasonal, with 75–85% of cases during the rainy season. It has a high case fatality rate (CFR) of 16% to 50% in endemic regions. Endemic areas include Southeast Asia, northern Australia, Indian subcontinent, southern China, Hong Kong, and Taiwan. Currently, no vaccine is available, but early diagnosis and treatment are crucial.

Notes:
Union Culture Minister Gajendra Singh Shekhawat inaugurated the Gyan Bharatam International Conference in New Delhi on 11 September. Gyan Bharatam is a national initiative for preserving, digitising, and disseminating India’s manuscript heritage. The mission envisions 25 clusters, 20 regional centres, and 10 centres of excellence to safeguard manuscripts. The conference brought together 1,100+ participants, including scholars, experts, institutions, and cultural practitioners from India and abroad.

Notes:
Recently, the first-of-its-kind Swastik Lotus Garden was inaugurated at the National Botanical Research Institute (NBRI), Lucknow, during the CSIR Startup Conclave. The garden features 60 lotus varieties from across the world and 50 species of water lilies. Conservation is ensured through advanced genetic methods, light regulation, and scientific treatments. CSIR technologies were transferred to private companies for public access, including perfumes Frotus-Rudra, Frotus-Kumbh, air-freshener Frotus Fresh, green firecrackers, aromatherapy oil Relaxomap, and portable water analysis kits. The initiative strengthens scientific innovation, conservation, and entrepreneurship at grassroots and national levels.

Notes:
Scientists at the University of Tasmania, Australia, developed a portable ion chromatograph called Aquamonitrix to perform ion separation in the field. The device was tested by undergraduate students who analysed soil pore water for harmful nitrate and nitrite ions immediately after collection. Results were comparable to expensive lab-based chromatographs, proving accuracy with lower cost and time. Aquamonitrix uses sodium chloride solution and a UV absorbance detector, making it simple, eco-friendly, and effective. The portable device costs about 10,000 versus 100,000 for conventional lab instruments. It provides hands-on field experience for students, linking theory with real-world environmental analysis.

Notes:
Indian Immunologicals Limited (IIL) has launched India’s first indigenously developed glycoprotein E (gE) deleted DIVA (Differentiated between Infected and Vaccinated Animal) marker vaccine against Infectious Bovine Rhinotracheitis (IBR) in Anand, Gujarat. IBR is caused by Bovine Herpes Virus-1 (BHV-1), belonging to the genus Varicellovirus under Alphaherpesvirinae subfamily. It mainly affects domestic and wild cattle. The disease has three forms – respiratory, genital and encephalitic, with respiratory and genital being common. Transmission occurs through aerosols and semen from bulls to milch animals, impacting the reproductive system.

Notes:
Astronomers have directly imaged a young planet, WISPIT 2b, forming inside a gap in a protoplanetary disk around a distant star. The discovery confirms that disk gaps are indeed caused by growing planets. WISPIT 2b is a gas giant, about five times the mass of Jupiter, and only five million years old. It orbits WISPIT 2, a young star 437 light-years from Earth. Protoplanetary disks are rings of gas and dust around young stars, providing planet-forming material. The planet was imaged using Very Large Telescope (VLT), MagAO-X on Magellan Clay Telescope, and Large Binocular Telescope.

Notes:
Kerala reported another death from Amoebic Meningoencephalitis (Primary Amebic Meningoencephalitis, PAM), raising the 2025 toll to 27 cases. Primary Amebic Meningoencephalitis is a rare, fatal brain infection caused by the free-living amoeba Naegleria fowleri, known as the “brain-eating amoeba.” Infection occurs when contaminated freshwater enters the nasal cavity, allowing the amoeba to reach the brain via the olfactory nerve. It is found in warm freshwater and soil, especially lakes, rivers, hot springs, and unchlorinated pools.
