Science & Technology Current Affairs MCQs

Notes:
In November 2025, Energy Efficiency Services Limited (EESL), a Joint Venture (JV) under the Ministry of Power (MoP), announced India’s largest Geothermal Energy Technology (GET) pilot project in Andhra Pradesh (AP). The project will be implemented at two tourism hubs — Araku Valley and Visakhapatnam (Vizag). It uses geothermal systems like Earth Air Tunnel (EAT) Systems and Ground Source Heat Pumps (GSHP). The system works by using the earth’s constant underground temperature at a depth of 7–8 meters (m) for eco-friendly heating and cooling. The technology has a short payback period of 3–4 years, ideal for hotels and tourism infrastructure.

Notes:
In November 2025, scientists from the Indian Institute of Astrophysics (IIA) collaborated with the National Aeronautics and Space Administration (NASA) to estimate key parameters of a Coronal Mass Ejection (CME). They used data from the Visible Emission Line Coronagraph (VELC) payload onboard India’s Aditya-L1 mission. VELC is the main payload of Aditya-L1, India’s first solar observatory placed 1.5 million kilometres from Earth. It is an internally occulted solar coronagraph capable of imaging, spectroscopy, and spectro-polarimetry near the solar limb.

Notes:
Australian scientists discovered a new native bee species named Lucifer. The species is scientifically called Megachile (Hackeriapis) Lucifer. It was first found in 2019 in Western Australia. This is the first new member of this bee group described in over 20 years. Australia has about 2,000 native bee species, with more than 300 yet to be scientifically named and described.

Notes:
Recently, the World Health Organization (WHO) confirmed Ethiopia’s first-ever outbreak of Marburg Virus Disease (MVD). MVD is a severe and often fatal hemorrhagic fever caused by the Marburg virus. It was first identified in 1967 in Marburg, Germany. The causative agents are Marburg virus (MARV) and Ravn virus (RAVV) of the species Orthomarburgvirus marburgense. The natural host is the fruit bat Rousettus aegyptiacus of the Pteropodidae family. It spreads from infected bats to humans and then through contact with bodily fluids or contaminated surfaces.

Notes:
Chinese researchers discovered tiny Iron oxide crystals (hematite and maghemite) in lunar soil for the first time using samples from China’s Chang’e-6 mission. The finding from the South Pole–Aitken (SPA) Basin challenges the old belief that the Moon’s reducing environment cannot form oxidized minerals. Chang’e-6 was the sixth robotic lunar exploration mission by the China National Space Administration (CNSA). The study in Science Advances confirms direct evidence of Iron oxide on the Moon. Scientists say massive ancient impacts created oxygen-rich vapour, leading to “vapour-phase deposition” of hematite crystals. These minerals, including maghemite, may explain magnetic anomalies in the SPA Basin. The breakthrough offers new insights into lunar history, composition, and future missions

Notes:
Recently, researchers from the Central Marine Fisheries Research Institute (CMFRI), Kochi discovered a new deep-sea squid species in the Arabian Sea and named it Taningia silasii (Indian octopus squid). The species was found at a depth of nearly 390 metres off the Kollam coast. It belongs to the family Octopoteuthidae. It is only the second formally recognised species in the Taningia genus. The first species in this genus was Taningia danae, earlier found in the Atlantic Ocean.

Notes:
The Entrepreneur-in-Residence Programme is becoming popular among young startups and innovators. It works under the National Initiative for Developing and Harnessing Innovations which is NIDHI. It encourages graduate students to choose entrepreneurship as a career. It provides financial and non-financial support in the form of a fellowship. It offers startup infrastructure, mentoring, technical guidance, and industry support. It is implemented by the Department of Science and Technology with NCL Venture Centre.

Notes:
Amyotrophic Lateral Sclerosis is a progressive neurological disorder that damages nerve cells controlling muscle movement. A study predicts global cases will rise from 222,801 in 2015 to 376,674 by 2040, a 69 percent increase. It is also called Lou Gehrig’s disease. It commonly affects people between 55 and 75 years and is more common in men. In some patients it is genetic but in most the cause is unknown. Damaged motor neurons stop brain signals from reaching muscles causing weakness and muscle wasting.

Notes:
Indian scientists developed a new Artificial Intelligence (AI) tool to improve cancer diagnosis and treatment at the molecular level. The tool, called OncoMark, was created by S. N. Bose National Centre for Basic Sciences and Ashoka University under the Department of Science and Technology (DST). It studies cancer through biological “hallmarks” like metastasis, immune evasion, and genomic instability. It goes beyond Tumor–Node–Metastasis (TNM) staging, which often misses hidden tumor behavior. The model was trained on 3.1 million single cells from 14 cancer types. It achieved over 99% accuracy in internal testing and 96% accuracy on patient data.

Notes:
Researchers at National Centre for Radio Astrophysics – Tata Institute of Fundamental Research (NCRA–TIFR), Pune, discovered a new spiral galaxy named Alaknanda. It lies 12 billion light years away and shows a perfect spiral structure. The name comes from the Alaknanda River and the Hindi word for the Milky Way. The galaxy spans 30,000 light years, with two clear spiral arms around a bright central bulge. It forms stars rapidly, producing 60 solar masses per year. It resembles a young Milky Way, formed when our galaxy was only 10% of its current age. The discovery was made using National Aeronautics and Space Administration (NASA)’s James Webb Space Telescope (JWST).
