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:
Researchers at Indian Institute of Technology-Madras (IIT-M) developed an agriculture waste-based packaging material. It offers a sustainable alternative to plastic foams like Expanded Polystyrene (EPS). Fungi such as Ganoderma lucidum (medicinal mushroom) and Pleurotus ostreatus (edible mushroom) were grown on waste. Five substrates were used: cardboard, sawdust, paper, cocopith, and hay. Ganoderma on cardboard showed higher compressive strength than EPS. India generates over 350 million tonnes of agricultural waste annually. This innovation can help reduce four million tonnes of plastic waste produced in India.

Notes:
Recently, Kerala’s health department issued an alert in Kozhikode after three cases of Primary Amoebic Meningoencephalitis (PAM) were reported. Primary Amoebic Meningoencephalitis (PAM) is a brain infection caused by Naegleria fowleri, also called the “brain-eating amoeba.” This amoeba lives in warm freshwater, soil, swimming pools, hot tubs, and infects through the nose. It mainly affects young, active people and has a mortality rate above 95%. Primary Amoebic Meningoencephalitis (PAM) progresses rapidly and is often fatal within days, while Granulomatous Amebic Encephalitis (GAE) progresses slowly.

Notes:
NASA announced that the James Webb Space Telescope (JWST) discovered a new 29th satellite of Uranus, named S/2025 U1. The moon has an estimated diameter of 10 kilometres and orbits Uranus at a distance of about 56,000 kilometres. S/2025 U1 will receive an official name from the International Astronomical Union (IAU) in the future. Uranus is the seventh planet from the Sun and the third-largest planet in the solar system. Uranus is an ice giant, composed mainly of hydrogen, helium, water, methane, and ammonia. Uranus now has 29 moons, with five major moons: Miranda, Ariel, Umbriel, Titania, and Oberon.

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:
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:
Researchers at S. N. Bose National Centre for Basic Sciences (SNBNCBS) discovered protein p47’s new role as a “mechanical chaperone.” P47 is a cofactor protein known for assisting p97 in protein trafficking, degradation, and membrane fusion. Study revealed p47 boosts mechanical efficiency of protein extraction from endoplasmic reticulum (ER) to cytoplasm. It stabilizes polypeptides under stress, guides them through pores, prevents misfolding, and improves translocation. This is the first single-molecule evidence of autonomous, force-dependent chaperone-like activity by p47. Discovery opens new therapeutic possibilities for diseases linked to protein instability.

Notes:
India has licensed Indian Immunologicals Limited, Techinvention Lifecare Private Limited, Panacea Biotec Limited, Biological E Limited, and Zydus Lifesciences for manufacturing its first indigenous multi-stage malaria vaccine (AdFalciVax). The vaccine was developed by Indian Council of Medical Research (ICMR) and partners. It targets Plasmodium falciparum before it enters the bloodstream to prevent transmission. The vaccine is affordable, stable, scalable, and effective for over 9 months at room temperature.

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.
