Science & Technology Current Affairs MCQs

Notes:
Recently, the blue rock pigeon, also called Columba livia, has been linked to concerns over spreading aspergillosis disease. Aspergillosis is an infection caused by Aspergillus, a mold genus with many species. The main infection-causing species is fungus “Aspergillus fumigatus”, which releases tiny airborne spores. These spores can cause respiratory illness when inhaled in large amounts, especially in people with weak immunity or lung issues. Aspergillosis is not contagious and doesn’t spread between people.

Notes:
Recently, a team from Indian Institute of Technology (IIT) Kanpur used Ground Penetrating Radar (GPR) to detect ancient Buddhist stupas and buried structures in Yamuna Nagar district, Haryana. Ground Penetrating Radar (GPR) is a high-resolution geophysical method that uses high-frequency electromagnetic waves to explore underground features. These waves interact with subsurface materials and are reflected, refracted, or scattered based on their type. GPR typically detects features up to a depth of around 10 meters. It is useful for locating bedrock depth, water tables, soil layers, buried stream channels, cavities, and fractures.

Notes:
The Indian Council of Medical Research (ICMR) is developing a new malaria vaccine called AdFalciVax to fight Plasmodium falciparum. This was recently highlighted due to its unique chimeric and recombinant design. AdFalciVax is being developed with Regional Medical Research Centre Bhubaneswar (RMRCBB), National Institute of Malaria Research (NIMR), and Department of Biotechnology – National Institute of Immunology (DBT-NII). It uses Lactococcus lactis, a safe food-grade bacterium, for production. The vaccine targets both the pre-erythrocytic and sexual stages of the malaria parasite. This dual-target approach offers both personal protection and reduction of mosquito transmission.

Notes:
Iran successfully launched its Nahid-2 telecommunications and research satellite on 27 July 2025. The launch was done aboard a Russian Soyuz rocket as part of a multi-payload mission. Other payloads included Russia’s Unisphere-M3 and M4 and 18 satellites from various countries. The Soyuz rocket had earlier launched Iranian satellites like Khayyam, Pars-1, Kosar, and Hodhod. Nahid-2 is designed to stay in orbit for five years. It has an indigenous propulsion system that can adjust its altitude by up to 50 kilometers. This propulsion is key for maintaining orbital position and operational stability.

Notes:
Recently, Bengaluru-based space company Protoplanet launched the Human Outer Planetary Exploration (HOPE) station in Ladakh’s Tso Kar region. HOPE is a moon and Mars simulation research station mimicking off-Earth terrain and environment. It is located in the high-altitude cold desert of Tso Kar basin, Ladakh. The project is developed by Protoplanet with technical and financial support from Indian Space Research Organisation (ISRO). It aims to study human psychological, physiological, and epigenetic responses in extreme isolation. It supports India’s long-term space goals including a crewed lunar mission by 2040 and a space station by 2035.

Notes:
Recently, reports claim the Trump administration asked NASA to shut down Orbiting Carbon Observatories (OCO). The Orbiting Carbon Observatory (OCO) Program, managed by NASA’s Jet Propulsion Laboratory (JPL), is an initiative of NASA. OCO are Earth remote sensing satellites designed to monitor atmospheric carbon dioxide (CO₂) from space to understand climate change.

Notes:
On 15 August 2025, Chinese commercial aerospace company Geespace successfully completed the fourth orbital deployment of GEESATCOM (Geely Constellation) by launching 11 satellites from waters off Rizhao, Shandong Province aboard a single rocket. All satellites entered their planned 600 km orbits and are operating normally. GEESATCOM, independently developed and operated by Geespace, supports satellite Internet of Things (IoT) testing and inter-satellite communications. It also provides Earth observation for ecological and environmental monitoring.

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:
The Department of Health and Human Services recently confirmed the first human case of the flesh-eating parasite, the New World screwworm, in the United States. New World screwworm is a blue-grey blowfly usually found in South America and the Caribbean. Its larvae burrow screwlike into living tissue, causing dangerous infestations. Female flies lay eggs in open wounds or cavities, with up to 3,000 eggs in their lifespan. Symptoms include non-healing wounds, bleeding, foul smell, and sensation of movement. Infestation is extremely painful and can be fatal if untreated.

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.
