Science & Technology Current Affairs MCQs

Notes:
The World Health Organization has issued the first global guidelines on Glucagon-Like Peptide-1 (GLP-1) drugs for weight loss. GLP-1 receptor agonists are synthetic medicines used to treat adult obesity and type-2 diabetes. These drugs are mainly injectable, while oral versions are under development. Leading examples are Semaglutide and Tirzepatide, now available in India. They increase insulin, reduce glucagon, slow stomach emptying, and suppress appetite, helping control blood sugar and body weight.

Notes:
A new study warns that heavy use of artemisinin and favourable conditions can create new hotspots of drug resistance, with resistance markers slowly rising in parts of Africa. Artemisinin is an antimalarial drug obtained from the sweet wormwood plant called Artemisia annua. It was discovered in the 1970s and became a major breakthrough when malaria parasites developed resistance to older drugs like chloroquine. It is effective against all malaria-causing parasites of the Plasmodium genus, mainly during the blood stage. Artemisinin quickly reduces parasites but stays in the body for a short time, so it is combined with other drugs. The World Health Organization recommends artemisinin-based combination therapies as the standard treatment for Plasmodium falciparum malaria.

Notes:
The Minister of Fisheries, Animal Husbandry and Dairying informed Rajya Sabha about white spot disease. It is a highly contagious viral infection affecting crustaceans like prawns, yabbies and crabs. It is caused by White Spot Syndrome Virus (WSSV). All decapod crustaceans (order Decapoda) from marine, brackish and freshwater environments are susceptible.

Notes:
Recent re-analysis of National Aeronautics and Space Administration (NASA) Cassini spacecraft data suggests that Saturn’s moon Titan may not have a subsurface ocean as earlier believed. Titan is the largest moon of Saturn and the second largest in the solar system after Ganymede. It was discovered by Dutch astronomer Christiaan Huygens. Titan has a radius of about 2,575 kilometres and is much wider than Earth’s Moon. It is the only moon with a dense atmosphere, mainly nitrogen with some methane. Titan is the only world besides Earth with rivers, lakes, and seas of liquid on its surface. It has an Earth-like methane cycle with rain, flow, and evaporation.

Notes:
Iran launched three domestically-built observation satellites—Zafar-2, Paya, and Kowsar 1.5—into space from Russia’s Vostochny Cosmodrome using a Soyuz rocket. The satellites were designed by Iran’s private sector for observation purposes. Paya is Iran’s most advanced imaging satellite, using artificial intelligence for higher-resolution images. The satellites will focus on water resource management, environmental monitoring, and mapping. The Soyuz rocket was chosen for its reliability in transporting sensitive satellites. Iran has conducted ten satellite launches in the last two years, including one in July 2025 from Russia.

Notes:
Abu Dhabi, United Arab Emirates (UAE),’s Sheikh Khalifa Medical City became the first hospital worldwide to administer ITVISMA gene therapy. ITVISMA is a one-time gene therapy for spinal muscular atrophy (SMA), given on 28 December 2025. It replaces the defective Survival Motor Neuron 1 (SMN1) gene. This enables production of survival motor neuron protein, targeting the root genetic cause. It is approved for patients aged two years and above, including adults. Spinal Muscular Atrophy (SMA) is a rare, progressive neuromuscular disorder causing muscle weakness and life-threatening complications. The therapy may improve motor function and reduce long-term treatment dependence.

Notes:
Recently, an observational study on cellulitis was published in the International Journal of Lower Extremity Wounds. Cellulitis is a common skin infection caused mainly by Streptococcus and Staphylococcus bacteria. It usually affects the legs, feet, and toes but can also involve face, arms, hands, and fingers. The infection affects tissues beneath the skin. Risk factors include skin wounds or a weakened immune system, which allow bacteria to enter easily. Cellulitis is generally not contagious, except rarely through open-wound contact with an infected person.

Notes:
The Union Minister Shri Rajiv Ranjan Singh inaugurated India’s first commercial-scale tropical Recirculating Aquaculture System (RAS)–based Rainbow Trout Aquaculture Farm & Research Institute on 5th January 2026 in Hyderabad, Telangana. The facility, established by Smart Green Aquaculture Limited at Kandukur Mandal, Ranga Reddy District, demonstrates year-round farming of high-value cold-water species like Rainbow Trout in tropical climates using precision engineering and advanced water recirculation technologies. The project serves as a live training and demonstration platform, providing youth hands-on experience in advanced aquaculture systems, automation, and biosecurity, strengthening human capital in the fisheries sector.

Notes:
Scientists recently used drones to detect a dangerous Cetacean morbillivirus (CeMV) among whales in the Arctic. Cetacean morbillivirus is a viral infection affecting marine mammals, especially cetaceans like whales, dolphins, and porpoises. CeMV has caused multiple outbreaks worldwide, particularly in the North Atlantic and the Mediterranean. Transmission occurs through respiratory routes and direct contact, with the virus shed via ocular and respiratory secretions, urine, feces, and sloughed skin. The virus affects the respiratory and neurological systems, leading to mass strandings and deaths of marine mammals.

Notes:
India inaugurated the world’s second National Environmental Standard Laboratory (NESL) and the world’s fifth National Primary Standard Facility for Solar Cell Calibration at CSIR–National Physical Laboratory (NPL), New Delhi. NESL will provide India-specific calibration and certification of air pollution monitoring systems, supporting regulatory bodies, industries, and startups, and improving policy enforcement under programmes like the National Clean Air Programme (NCAP).
