Science & Technology Current Affairs MCQs

Notes:
Recently, a new blood group named CRIB was discovered in a South Indian woman from Kolar district, Karnataka. The discovery was announced at the 35th Regional Congress of the International Society of Blood Transfusion (ISBT) held in Milan, Italy. CRIB stands for Cromer India Bangalore and is part of the Cromer (CR) blood group system. This blood group was previously unidentified anywhere in the world. The discovery took 10 months of research and molecular testing by international experts.

Notes:
Recently, the World Health Organisation (WHO) certified Kenya as having eliminated human African trypanosomiasis (HAT), also known as sleeping sickness. It is a parasitic disease spread by infected tsetse fly bites, endemic in sub-Saharan Africa. It has two forms: Trypanosoma brucei gambiense (92% cases, chronic, found in West and Central Africa) and Trypanosoma brucei rhodesiense (8% cases, acute, found in East and Southern Africa). Rural communities relying on farming, fishing, herding, or hunting face higher risk. WHO has validated the gambiense form’s elimination in Togo, Benin, Ivory Coast, Uganda, Equatorial Guinea, Ghana, Chad, Guinea, and now Kenya.

Notes:
Union Minister of State for Science & Technology Jitendra Singh inaugurated India’s first ‘Animal Stem Cell Biobank’ at National Institute of Animal Biotechnology (NIAB), Hyderabad. NIAB is under Department of Biotechnology’s Biotechnology Research Innovation Council (BRIC). The Biobank will store high-quality stem cells from various animal species and supply cost-effective culture media to veterinary clinics, research bodies, and industry.

Notes:
NASA has launched “Surya”, an artificial intelligence (AI) model to improve space weather forecasting. Surya was developed in collaboration with IBM and trained on over nine years of data from NASA’s Solar Dynamics Observatory (SDO). It analyses massive streams of solar activity to detect early signs of solar flares and coronal mass ejections (CMEs). Solar storms can disrupt satellites, communication systems, aviation, GPS navigation, and power grids on Earth. Surya generates visual forecasts up to two hours in advance with higher accuracy than traditional methods. The model is open-source to enable global researchers to improve space weather defense.

Notes:
Huntington’s Disease (HD) is not yet included in the rare disease category under the National Policy for Rare Diseases despite demands from patients and caregivers in 2024. It is a genetic condition that affects brain cells, causing them to slowly lose function and die. It is inherited, with a 50% chance of passing from an affected parent to a child. It impacts brain regions controlling voluntary movement, memory, thinking, and decision-making, including the basal ganglia and cortex.

Notes:
Odisha Chief Minister Mohan Charan Majhi unveiled India’s first Integrated Global Financial Technology Capability Hub (I-GFTCH) in Bhubaneswar under the BharatNetra initiative. It is launched with Singapore-headquartered Global Finance and Technology Network (GFTN). It aims to promote entrepreneurship, industry-ready skills, inclusive finance, and employment. Odisha plans Deep Neural Network laboratories and centres of excellence to boost research and development (R&D). The state produces 1.8 lakh graduates annually and is first in India to implement an Artificial Intelligence (AI) policy. A dedicated FinTech and Global Capability Centre (GCC) policy will attract global investments.

Notes:
Gaza has recently reported a surge in Guillain-Barré Syndrome (GBS), raising health concerns. Guillain-Barré Syndrome (GBS) is a rare autoimmune condition where the immune system attacks the peripheral nervous system. The peripheral nervous system controls muscle movement, pain, temperature, and touch sensations. It is also called Acute Inflammatory Demyelinating Polyradiculoneuropathy (AIDP). It commonly affects people between 30 and 50 years of age. It usually follows viral or bacterial infections, vaccination, or surgery.

Notes:
Matanomadh, a remote village in Kutch district, Gujarat, may serve as a test bed for ISRO’s Mangalyaan-2 mission to Mars. Researchers from Space Applications Centre (SAC) Ahmedabad, Savitribai Phule Pune University (SPPU), and Birbal Sahni Institute of Palaeosciences, Lucknow dated jarosite mineral in Matanomadh to 55 million years (Paleocene period). Jarosite is a yellow, iron-rich sulphate mineral, similar to those found on Mars, indicating past water activity. The site allows field-analogue studies for Mars, including rover testing, drilling, geochemistry, and astrobiology research. The discovery can help decode Martian geology, past chemical interactions, and organic molecule trapping, aiding future Mars missions.

Notes:
A team of Indian and international researchers has discovered a new diatom species named Climaconeis heteropolaris in Udupi estuarine waters. It was found where the Sita and Swarna rivers meet before entering the Arabian Sea, Karnataka. Diatoms are photosynthetic, single-celled microscopic algae forming a key part of phytoplankton. They are found in lakes, ponds, rivers, streams, and oceans worldwide. Some float freely in water, while others attach to plants, rocks, or sediments as benthic diatoms. Diatoms produce oxygen, support aquatic life, and generate up to 50% of global atmospheric oxygen annually. They are vital in nutrient cycling of both marine and freshwater ecosystems.

Notes:
Cholesterol, a fat-like substance, can control the spin of electrons, a quantum property crucial for next-generation spintronic devices. Spintronics uses electron spin to develop energy-efficient electronics and bioelectronic devices. Scientists from the Institute of Nano Science and Technology (INST), Mohali, under the Department of Science and Technology (DST), developed cholesterol-based nanomaterials for spintronic and quantum applications. Cholesterol’s intrinsic handedness (chirality) and flexibility allow precise control over molecular properties. This innovation could enable energy-efficient memory chips and greener quantum technologies.
