Science & Technology Current Affairs MCQs

Notes:
China has launched the “Three Gorges Antarctic Eye,” a 3.2-metre aperture radio and millimetre-wave telescope at Zhongshan Station in Antarctica. It is designed to study interstellar gas like hydrogen and ammonia and to explore star formation in deep space. The telescope can operate in Antarctica’s extreme cold and strong winds, making it a major engineering success. It builds on China’s earlier Antarctic Survey Telescopes (AST3) projects. The telescope was developed by China Three Gorges University and Shanghai Normal University to boost China’s space science research.

Notes:
The Karlsruhe Tritium Neutrino (KATRIN) experiment in Germany has made a major advance in particle physics as of April 2025. Neutrinos are neutral subatomic particles formed in radioactive decay and nuclear reactions like those in the sun and stars. The KATRIN (Karlsruhe Tritium Neutrino) experiment, located in Karlsruhe, Germany, aims to measure the mass of the electron antineutrino, which is produced during beta decay. The latest results from KATRIN have reduced the upper limit of neutrino mass to less than 0.45 electron volts, marking a 50% improvement.

Notes:
The Kerala State Electricity Board (KSEB) and Indian Institute of Technology Bombay (IIT Bombay) have launched a pilot Vehicle-to-Grid (V2G) project in Kerala. Vehicle-to-Grid (V2G) is a technology that allows Electric Vehicles (EVs) to send stored power back to the grid when not in use. V2G is the most studied application, though it is part of a broader framework including Vehicle to Home (V2H) and Vehicle to Vehicle (V2V) systems.

Notes:
In a big step towards clean nuclear energy, China has launched the world’s first Thorium Molten Salt Reactor (TMSR) in Wuyi City, Gansu Province, located in the Gobi Desert. This thorium-based reactor started in October 2023 and generates 2 megawatts (MW) of electricity. The project received a $444 million investment since 2011 and is a major shift in global nuclear innovation during China’s trade tensions with the United States (US). China plans to build a 10 MW version by 2030, showing long-term goals in clean energy. Thorium is safer than uranium, creates less radioactive waste, and cannot be easily used for weapons. It must be turned into Uranium-233 (U-233) to be used in reactors, making it complex but promising for safe and sustainable energy.

Notes:
Recently, the government selected Bengaluru-based start-up Sarvam to build India’s first indigenous artificial intelligence (AI) large language model (LLM) under the ₹10,370 crore IndiaAI Mission. This project aims to create a strong AI infrastructure fully built, deployed, and optimized within India to strengthen strategic autonomy. Sarvam AI was chosen after a tough selection process among 67 applicants and will get access to 4,000 high-end Graphics Processing Units (GPUs) for six months to develop the model. This move is significant as it boosts India’s leadership in AI and promotes innovation through homegrown technologies. It comes amid rising competition from China’s low-cost DeepSeek model.

Notes:
A recent study by the Global Antibiotic Research and Development Partnership (GARDP) showed that many multidrug-resistant infections in low- and middle-income countries, including India, are not being treated properly due to lack of access. GARDP is a not-for-profit organization that creates new antibiotic treatments for drug-resistant bacterial infections and ensures they reach people in need. It focuses on public health by developing antibiotics to fight the current antimicrobial resistance (AMR) crisis and protect future generations. GARDP was founded by the World Health Organization (WHO) and Drugs for Neglected Diseases initiative (DNDi) under the Global Action Plan on AMR in 2015.

Notes:
In a major step toward digital transformation, Chhattisgarh Chief Minister laid the foundation for India’s first Artificial Intelligence-based Data Center Park in Raipur. The facility will start with a five megawatt capacity and aims to grow to 150 megawatts. A 2.7-hectare area is being developed as a Special Economic Zone (SEZ) focused on Artificial Intelligence (AI) services. The project will see an investment of Rs 2,000 crore as it expands. The center will support green, energy-efficient technologies for sustainable operations. It will serve sectors like AI, Financial Technology (FinTech), Health Technology (HealthTech), defense, and data analytics. The infrastructure will use Graphics Processing Unit (GPU)-based systems for real-time data processing, streaming, and analytics.

Notes:
Indian and US researchers have recently discovered a new subtype of Maturity-Onset Diabetes of the Young (MODY), a rare, inherited form of diabetes. MODY is caused by genetic mutations that lead to impaired insulin production or function. It is typically diagnosed in adolescents or young adults under 35 years of age, without significant obesity. The discovery was made by researchers from the Madras Diabetes Research Foundation (MDRF) in Chennai and Washington University School of Medicine in St. Louis. This breakthrough could change the way certain forms of MODY are diagnosed and treated, offering better solutions for patients. MODY is divided into 14 subtypes, each linked to different gene mutations.

Notes:
The MADMAX collaboration recently published the first results of its search for dark photons using a prototype detector. MADMAX stands for Magnetised Disk and Mirror Axion Experiment. It is a research project focused on detecting dark matter particles like axions and dark photons. The MADMAX detector uses a system made of sapphire disks and a mirror to form a resonator that enhances detection signals. Dark photons are theoretical particles similar to light particles (photons) but have mass. They are believed to be part of galactic dark matter and can turn into ordinary photons under special conditions.

Notes:
India has launched its first 3-nanometre (3nm) chip design centres in Noida and Bengaluru, marking a major step in advanced semiconductor development. These centres have been set up by Renesas Electronics India Private Limited, placing India among a few nations working on next-generation chip design. The initiative is part of a broader government plan to build a complete semiconductor ecosystem including design, fabrication, ATMP (Assembly, Testing, Marking, and Packaging), and supply chain support.
