Science & Technology Current Affairs MCQs

Notes:
Astronomers from Aryabhatta Research Institute of Observational Sciences studied the W Ursae Majoris (W UMa) star. They used data from Devasthal Fast Optical Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS). W UMa is a low-mass contact binary and an eclipsing binary variable star. The two stars share a single outer atmosphere and orbit each other. W UMa stars show light curves with nearly equal minima and continuous brightness variation. Studying W UMa helps determine stellar masses, radii, and temperatures, aiding understanding of stellar evolution.

Notes:
The Council of Scientific and Industrial Research–National Physical Laboratory (CSIR–NPL) established the National Environmental Standard Laboratory (NESL). It is located at the CSIR–National Physical Laboratory in New Delhi. It was set up to test and recalibrate air pollution monitoring instruments and environmental sensors under Indian conditions. It ensures reliable and credible data for the National Clean Air Programme (NCAP). It allows manufacturers, industries, and municipal bodies to validate instrument performance within India. It supports industrial emission audits, smart city monitoring networks, and provides reference gases and standard protocols.

Notes:
The United States Food and Drug Administration (FDA) approved Zycubo, a copper histidinate injection, as the first treatment for Menkes disease in children. Menkes disease is a rare genetic disorder that affects the body’s ability to process copper. It is caused by mutation of the ATP7A gene located on the X chromosome, affecting copper transport and balance. Copper is essential for metabolism, brain function, blood formation, immunity, wound healing, and iron use. The disease leads to low copper levels in blood, liver, and brain, reducing copper-dependent enzyme activity.

Notes:
Artemis II is the first crewed mission of NASA’s Artemis programme and will mark humanity’s return to the Moon’s vicinity for the first time since 1972. The 10-day mission will test the Space Launch System (SLS) rocket and the Orion spacecraft to verify life-support, navigation, and safety systems for future lunar missions. On January 9, NASA announced that Artemis II had entered its final preparation phase. The fully assembled rocket is expected to be rolled out to Launch Pad 39B at the Kennedy Space Centre in mid-January for final testing.

Notes:
Odisha plans to launch India’s first state-wide Chronic Kidney Disease (CKD) registry by 31 March, marking a national first. The registry will help the government assess CKD prevalence and design targeted action plans and health programmes. A state task force and a technical working group with experts from health institutes, research bodies, and departments have been formed. All health facilities, from Primary Health Centres (PHCs) to medical colleges, will report Chronic Kidney Disease cases. The National Informatics Centre (NIC) is developing the registry software.

Notes:
Recently, researchers at the National Centre for Biological Sciences (NCBS), Tata Institute of Fundamental Research (TIFR), Bengaluru, developed a deep-learning tool called Disobind. Disobind predicts how intrinsically disordered proteins (IDP) bind to their partner proteins. Intrinsically Disordered Proteins (IDPs) are shapeshifting proteins without fixed structure, crucial for cell signalling, gene regulation, and protein movement. Their flexibility makes them hard to study using traditional structural biology methods. Disobind uses protein language models trained on millions of protein sequences.

Notes:
ExoMiner++ is a new deep learning software designed to discover exoplanets. It is developed by NASA (National Aeronautics and Space Administration). It analyses data from both the Kepler and TESS (Transiting Exoplanet Survey Satellite) missions. The software scans stellar “light curves” for dips in brightness caused by planets transiting in front of their stars. Unlike standard black-box models, ExoMiner++ is an explainable AI, offering probability scores and reasoning to help astronomers verify and trust its findings.

Notes:
According to the World Health Organization (WHO), scabies is among the most common skin diseases in developing countries. Scabies is a contagious parasitic skin infestation found worldwide. It is caused by the Sarcoptes scabiei mite, which burrows under the skin and causes an itchy rash. It is more common in hot and tropical regions like India. WHO classifies scabies as a Neglected Tropical Disease due to its impact on poor communities.

Notes:
Indian Institute of Technology (IIT) Kanpur researchers developed a new method to predict solar cycles. A solar cycle is an about 11-year cycle of solar activity controlled by the Sun’s magnetic field. It is measured by the number and intensity of sunspots seen on the Sun’s surface. Around every 11 years, the Sun’s magnetic field flips, swapping north and south poles. Sunspots increase and decrease as magnetic activity changes on the Sun. The cycle starts with solar minimum, when sunspots are very few. Activity rises to solar maximum, when sunspots are highest. After this, activity declines back to solar minimum and a new cycle begins.

Notes:
Bharat-VISTAAR (Virtually Integrated System to Access Agricultural Resources) is a proposed multilingual Artificial Intelligence (AI)-powered platform for farmers, announced in Union Budget 2026-27 by Union Finance Minister Smt. Nirmala Sitharaman. It will integrate AgriStack portals and ICAR (Indian Council of Agricultural Research) agricultural practices with AI systems. The platform aims to enhance farm productivity and reduce risks for farmers by providing customised, real-time advisory support to improve decision-making based on local conditions.
