Science & Technology Current Affairs MCQs

Notes:
Norovirus outbreaks in the United States (U.S.) have risen sharply, with 91 cases in early December, up from 69 in late November. Norovirus is a highly contagious virus causing gastroenteritis, also known as the “stomach flu” or “winter vomiting bug.” It affects people of all ages and spreads quickly through contaminated food, water, surfaces, or close contact. Noroviruses cause 90% of viral gastroenteritis outbreaks and nearly 50% of cases worldwide. People can get infected multiple times due to the variety of norovirus strains. Preventive measures focus on hygiene and proper food handling to limit its spread.

Notes:
Scientists are using two telescopes as part of the Cubic Kilometre Neutrino Telescope (KM3NeT) to detect high-energy neutrinos beneath the Mediterranean Sea. The Cubic Kilometre Neutrino Telescope (KM3NeT) is located at the bottom of the Mediterranean Sea. Neutrinos are tiny, electrically neutral particles, discovered in 1959, and the second most abundant particles after photons. They rarely interact with matter, earning the nickname “ghost particles.” Detecting neutrinos is challenging due to their minimal interactions. KM3NeT, an underwater telescope, detects neutrino interactions via Cherenkov radiation in the sea, which provides ideal conditions for detection.

Notes:
Nadi Tarangini, India’s first Ayurvedic medical device, received approval from Central Drugs Standard Control Organization (CDSCO). It costs ₹55,000 and is manufactured by Atreya Innovations in Pune. The device analyzes 22 Ayurvedic parameters and provides a 10-page report in 10 Indian languages. It has an accuracy of 85% and is used in over 1250 Ayurvedic clinics. Nadi Tarangini received patents in the US, Europe, Indonesia, and India.

Notes:
AnemiaPhone, developed by Cornell University, is now part of Indian Council of Medical Research (ICMR) programs for anemia, women’s health, and maternal and child health in India. It offers quick, accurate, and low-cost iron deficiency assessment. Anemia affects 50% to 70% of pregnant women in India, with iron deficiency as the main cause. The device uses a drop of blood on a test strip, similar to a COVID-19 test, providing results in minutes. Data is uploaded to a clinical database via mobile devices, enabling healthcare workers to provide immediate guidance, referrals, or interventions.

Notes:
Researchers discovered two rare Neuroptera species, Indophanes barbara and Glenochrysa zeylanica, in Kerala. Indophanes barbara, an antlion from the Myrmeleontidae family, does not build pits like other antlion larvae and lives in loose soil for protection. Adult Indophanes barbara resemble damselflies but can be identified by their long antennae and belong to holometabolous Neuroptera insects, unlike hemimetabolous damselflies. Glenochrysa zeylanica, a green lacewing from the Chrysopidae family, was rediscovered in Wayanad after 111 years and reported for the first time in India. Neuroptera, commonly called lacewings, are terrestrial insects with complex wing vein patterns.

Notes:
India launched the Indian Biological Data Centre (IBDC) Portals, making 10,000 whole genome samples accessible globally. The data set enables advancements in genomics, personalized healthcare, and medicine. IBDC supports seamless access to genetic data, aiding researchers in studying genetic variations and developing precise genomic tools. The Framework for Exchange of Data Protocols (FeED) ensures ethical and secure genomic data sharing under Biotech-PRIDE Guidelines. The GenomeIndia project, led by Department of Biotechnology (DBT), creates a comprehensive genetic diversity database for cutting-edge research. India plans to sequence 10 million genomes, enhancing innovation in healthcare, agriculture, and biotechnology.

Notes:
LingoSat, a joint project of Japan’s Kyoto University and Sumitomo Forestry, is the first wooden satellite launched into orbit. It uses wood from honoki, a magnolia tree native to Japan, and is assembled using traditional Japanese crafts without screws or glue. The satellite’s name comes from the Latin word “Ligno,” meaning wood. LignoSat 1 is a CubeSat measuring 10 cm on each side and weighing 900 grams. LignoSat 2, a 2U CubeSat, is planned for launch in 2026.

Notes:
More than 30 dermatologists suggest renaming the fungus Trichophyton indotineae as its origin in India is unconfirmed despite reports from over 40 countries. Trichophyton indotineae is a fungal pathogen causing severe, treatment-resistant skin infections. It was named after India in 2020 based on isolates from India and Nepal. The fungus belongs to the dermatophyte group, causing dermatophytosis, which affects the skin, hair, and nails. It causes itchy, inflammatory infections on the groin, gluteal region, trunk, and face, affecting all ages and genders. It spreads via direct skin contact or contaminated objects and is resistant to terbinafine.

Notes:
New research reveals that genetic mutations in Huntington’s Disease (HD) can have delayed effects, impacting disease progression over time. Huntington’s Disease (HD) is a genetic condition causing gradual loss of brain cell function, leading to their death. It affects brain regions regulating voluntary movement, memory, and decision-making, primarily the basal ganglia and brain cortex. HD is caused by a mutation in the HTT gene, which produces huntingtin protein crucial for neuron function. Mutated huntingtin proteins have abnormal shapes, damaging and killing neurons. HD is inherited; each child of an affected parent has a 50% chance of developing the disease. It affects 3 to 7 out of 100,000 people, primarily of European ancestry.

Notes:
IIT-Madras has launched a zero-waste bioplastics initiative supported by the Ministry of Chemicals and Fertilisers. The initiative aims to develop biodegradable, microplastic-free, and cost-effective alternatives to conventional plastics. Third-generation bioplastics use agricultural residues, algae, and waste materials, avoiding food security concerns linked to earlier food-based bioplastics. These bioplastics fully decompose, leaving no harmful particles behind, reducing the environmental footprint. The centre is also exploring bioplastics for food packaging and medical textiles, including biodegradable implants from agricultural waste.
