Science & Technology Current Affairs MCQs

Notes:
Recent research shows that eating diets high in Ultra Processed Foods (UPFs) can worsen gut inflammation and increase Crohn’s disease flare-ups. Crohn’s Disease is a chronic Inflammatory Bowel Disease (IBD) that causes swelling and irritation in the digestive tract. It usually affects the small intestine and the beginning of the large intestine. Inflammation can spread deep into the bowel layers, causing pain and serious complications. Common symptoms include diarrhea, abdominal cramps, and weight loss. It mostly develops between ages 20 and 29. The exact cause is unknown but may involve genes, immune reactions, and the microbiome. There is no cure, but treatment helps control symptoms and maintain remission.

Notes:
Hyderabad recently became home to India’s first-ever Semiconductor Innovation Museum, launched by T-Chip (Technology Chip Innovation Programme). The museum aims to showcase cutting-edge research and technological advancements in chipmaking. It positions Hyderabad as a hub for semiconductor innovation. The museum will feature exhibits on AI chips, robotics, reusable rocket engines, next-generation EV and display systems. It includes a 30-day Innovation Residency Model to connect startups, research institutions, and global innovators with investors and academia. The initiative strengthens India’s semiconductor ecosystem and fosters collaboration between innovators, investors, and academia.

Notes:
Recently, the PUNCH Space Mission, launched by the National Aeronautics and Space Administration (NASA), observed solar winds. PUNCH stands for Polarimeter to Unify the Corona and Heliosphere. Its aim is to study the Sun’s corona (outer atmosphere) and solar wind as a unified system. The mission has four small satellites in low Earth orbit. They make 3D global observations of the inner heliosphere and map the transition where the corona becomes solar wind.

Notes:
Researchers at Nagaland University discovered that Sinapic acid significantly accelerates wound healing in diabetic conditions. Sinapic acid is a natural phenolic acid derived from cinnamic acid. It has antioxidant, antitumor, anti-inflammatory, antibacterial, and neuroprotective properties. It is found in spices, citrus and berry fruits, vegetables, cereals, and oilseed crops. The compound activates the SIRT1 (Sirtuin 1) pathway, aiding tissue repair, angiogenesis, and inflammation control. This discovery could lead to safe, natural, and effective diabetic wound treatments. Diabetic wounds are slow-healing sores, mostly on the foot, increasing risk of neuropathy, poor circulation, infections, and amputation. Diabetes mellitus is a metabolic disease causing high blood glucose levels and affects hundreds of millions globally.

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.

Notes:
The Anusandhan National Research Foundation (ANRF), in collaboration with Indian Council of Medical Research (ICMR) and the Gates Foundation, launched the Mission for Advancement in High-Impact Areas (MAHA)-Medical Technology recently. MAHA MedTech Mission aims to boost innovation in India’s medical technology sector, reduce dependence on high-cost imports, and ensure affordable, high-quality medical technologies. The mission supports development and commercialization of innovative and affordable MedTech solutions.

Notes:
In a historic milestone, Prime Minister Narendra Modi unveiled NexCAR19, India’s first indigenous CAR-T Cell Therapy, at the Emerging Science, Technology & Innovation Conclave (ESTIC) 2025 in Delhi. It is developed by ImmunoACT, an IIT Bombay spin-off. It is supported by the Department of Biotechnology (DBT) and Biotechnology Industry Research Assistance Council (BIRAC). NexCAR19 is the world’s first humanised CAR-T therapy, truly “Made in India, for the world.” CAR-T Cell Therapy is an immunotherapy that reprograms a patient’s immune cells to fight blood cancers like Acute Lymphocytic Leukemia (ALL).

Notes:
Eli Lilly’s weight-loss drug Mounjaro became India’s top-selling drug by value in October 2025. It overtook GlaxoSmithKline’s (GSK) Augmentin, a widely used antibiotic. Mounjaro earned ₹1 billion ($11.38 million) in October, while Augmentin made ₹800 million. By volume, Augmentin sold 5,784 units, whereas Mounjaro sold only 85 units due to its high price. Mounjaro helps control blood sugar and slow digestion and belongs to the GLP-1 receptor agonist class used for obesity and diabetes. It was launched in India in March 2025 and has earned ₹3.33 billion till October. Mounjaro’s consumption was 10 times higher than rival Wegovy by Novo Nordisk, launched in June 2025. Eli Lilly sold 262,000 units, while Novo Nordisk sold 26,000 units in October.

Notes:
Recently, researchers found that male and female brains respond differently as Batten Disease progresses, opening new paths for treatment. Batten Disease is a rare genetic disorder affecting the brain and nervous system. It is congenital, progressive, and terminal, leading to steady decline in nervous system function. Symptoms include loss of vision and seizures, beginning in infancy, childhood, or rarely adulthood. Life expectancy varies from early childhood to the twenties depending on the form.

Notes:
Scientists in Thailand have discovered a new spider species named Damarchus inazuma that is half male and half female. It was found by researchers from Chulalongkorn University in a forest near Nong Rong, Thailand. The spider’s body is perfectly split — left side female with larger fangs and orange colour, and right side male with smaller size and greyish tone. This condition is called gynandromorphism, where an organism has both male and female tissues and traits.
