Science & Technology Current Affairs MCQs

Notes:
Scientists at the Raman Research Institute (RRI), Bengaluru have developed a novel, non-invasive technique to measure the local density of cold atoms in real time without disturbing their quantum state. The method, called Raman Driven Spin Noise Spectroscopy (RDSNS), overcomes limitations of conventional atom-imaging methods used in cold atom experiments. Cold atoms, cooled near absolute zero, are crucial for quantum computing, quantum sensing, and precision measurement, but traditional detection methods like absorption and fluorescence imaging are often destructive or slow.

Notes:
Indian Space Research Organisation (ISRO)’s Polar Satellite Launch Vehicle-C62 (PSLV-C62) mission faced an anomaly at the end of the third stage (PS3), and a detailed technical investigation has been started. PSLV-C62 is a multi-payload mission carrying one primary satellite and 18 secondary payloads. It is ISRO’s first space launch of the year 2026, scheduled from Sriharikota spaceport. The primary payload is Earth Observation Satellite-N1 (EOS-N1), codenamed Anvesha. EOS-N1 is a hyperspectral imaging satellite developed mainly for the Defence Research and Development Organisation (DRDO).

Notes:
A rare blood-red aurora was recorded at the Indian Astronomical Observatory using an all-sky camera in Hanle, Ladakh. Hanle Dark Sky Reserve is located at about 4,500 metres altitude in the Changthang region of Ladakh. It lies within the Changthang Wildlife Sanctuary and has Bortle-1 category skies, the darkest level. It was notified in December 2022 and is India’s first International Dark Sky Reserve. The reserve is managed by the Indian Institute of Astrophysics under the Department of Science and Technology. It aims to reduce light pollution and promote astro-tourism for local livelihoods.

Notes:
Union Minister Dr. Jitendra Singh launched the first open call of the Technology Development Board (TDB) under the Research, Development and Innovation (RDI) Fund. The initiative has been launched under the Anusandhan National Research Foundation (ANRF) to support indigenous technology commercialisation. The RDI Fund provides long-term, low-interest financing to high-risk, high-impact private sector innovations. It has a corpus of ₹1 lakh crore with 2–4 percent interest and repayment up to 15 years. The first call targets Technology Readiness Level (TRL) 4 and above projects in areas like artificial intelligence and deep-tech.

Notes:
The European Space Agency (ESA) released a high-resolution satellite image through the Copernicus Sentinel-2 mission. The image captures the venues planned for the 2026 Winter Olympic Games. The image highlights land features, terrain, and human-made infrastructure in great detail. The Copernicus Sentinel-2 mission is an Earth observation satellite mission developed by the European Space Agency (ESA). It is part of Copernicus, the European Union’s Earth observation programme. The mission focuses on monitoring changes and variability in land surface conditions.

Notes:
India launched iLive Connect, the world’s first doctor-led Artificial Intelligence (AI) healthcare ecosystem for continuous home-based clinical monitoring. It bridges gaps in chronic disease care and post-hospital recovery, especially for elderly and remote-area patients. The system uses medical-grade wearable biosensors, a chest patch and wristband, to track ECG, heart rate, respiration, oxygen saturation (SpO₂), temperature, blood pressure trends, activity, sleep, and heart rate variability. Data is sent in real time to a 24×7 medical command centre staffed by specialist doctors.

Notes:
Ministry of Science and Technology launched the BIRAC-Research, Development and Innovation Fund in New Delhi for biotechnology and related sectors. The fund aims to promote deep tech innovations and indigenous manufacturing with national impact. India’s bioeconomy has grown significantly over the past decade, from $8 billion in 2014. The launch reflects a government approach under Prime Minister Narendra Modi, positioning India for a global role in biotechnology. The number of biotechnology startups in India has increased to nearly 11,000 today.

Notes:
A new meat-eating dinosaur named Spinosaurus mirabilis was discovered in the Sahara Desert. Its fossils were found in Jengueb area of Niger in the central Sahara. It lived about 95 million years ago in a forested inland region with rivers. It is the second known species of Spinosaurus. The first species, Spinosaurus aegyptiacus, was discovered in 1915 in Egypt.

Notes:
Health and Family Welfare Minister Jagat Prakash Nadda launched indigenous Tetanus and Diphtheria vaccine at Central Research Institute, Kasauli in Solan district, Himachal Pradesh. Vaccine supports vision of Atmanirbhar Bharat in health sector. India is known as Pharmacy of the World. Universal Immunization Programme (UIP) is world’s largest immunization programme. Central Research Institute will supply 5.5 million vaccine doses by April 2026 to strengthen immunization coverage.

Notes:
Astronomers using the MeerKAT telescope in South Africa discovered the brightest and most distant megamaser. MeerKAT is a precursor to the Square Kilometre Array (SKA) telescope located in South Africa. It is designed for advanced radio astronomy. A megamaser is a giant beam of electromagnetic radiation produced when two galaxies collide violently. During such cosmic mergers, large gas clouds compress, exciting hydroxyl (OH) molecules, which emit high-energy microwaves.
