Science & Technology Current Affairs MCQs

Notes:
NISAR (NASA-ISRO Synthetic Aperture Radar) is a joint satellite mission by the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO). It is set to be launched in June 2025 from the Satish Dhawan Space Centre in Andhra Pradesh using the Geosynchronous Satellite Launch Vehicle Mark II (GSLV Mk II). This is the first radar-based Earth observation mission jointly developed by India and the United States. NISAR will map the entire Earth’s surface every 12 days to provide frequent and accurate data. It will track ecosystem changes, ice movements, vegetation shifts, sea level rise, groundwater levels, and natural disasters like earthquakes, volcanoes, tsunamis, and landslides.

Notes:
The Indian Space Research Organisation (ISRO) has predicted that wheat production from eight major states will reach 122.724 million tonnes by March 31, 2025. This estimate was made using satellite-based remote sensing technology for better accuracy and timely updates. ISRO’s National Remote Sensing Centre (NRSC) has developed a system called CROP, which stands for Comprehensive Remote Sensing Observation on Crop Progress. CROP is a semi-automated and scalable system that monitors crop sowing, growth, and harvesting in near real-time. It mainly supports agricultural planning during the Rabi season. This comes as remote sensing in agriculture marks 50 years of global use.

Notes:
Researchers at the Institute of Advanced Study in Science and Technology (IASST), Guwahati, have developed a new optical sensing platform for detecting cholesterol. This platform can detect cholesterol even in trace amounts, below the normal preferred range, making it useful for early disease detection. It is designed to help in regular and efficient monitoring of cholesterol levels in the human body. Cholesterol is an essential lipid produced by the liver and is vital for the functioning of animal tissues, blood, and nerve cells. In mammals, it is transported through the bloodstream to perform various biological functions.

Notes:
AIIMS Raipur has successfully performed its first Swap Kidney Transplant, also known as a Kidney Paired Transplant. With this, it became the first among the newer All India Institute of Medical Sciences (AIIMS) and the first government hospital in Chhattisgarh to perform this complex surgery. The Union Ministry of Health and Family Welfare highlighted it as a major step in advanced healthcare. This procedure helps patients with end-stage kidney disease by increasing transplant options through donor pairing. Swap Kidney Transplant is estimated to boost the number of kidney transplants by 15 percent. The National Organ and Tissue Transplant Organisation (NOTTO) has recommended all states and Union Territories adopt this method to improve donor availability.

Notes:
China has officially launched the world’s first commercial 10 Gigabit per second (10G) broadband network, setting a new global standard for high-speed wired internet. This new 10G broadband offers speeds over 10 times faster than current fiber-optic networks used around the world. It allows ultra-fast downloads and uploads, very low latency, and high bandwidth capacity. It supports advanced applications like 8K video streaming, cloud gaming, smart cities powered by Artificial Intelligence (AI), and virtual reality.

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:
The Indian Space Research Organisation (ISRO) has successfully conducted the second short hot test of the semicryogenic engine that will power the Semicryogenic booster stage of the Launch Vehicle Mark-3 (LVM3). A semicryogenic engine uses a cryogenic oxidizer like Liquid Oxygen and a hydrocarbon-based fuel like kerosene. It combines the advantages of cryogenic and conventional engines, offering better efficiency and operational simplicity. In comparison, a fully cryogenic engine uses both fuel and oxidizer in liquid form, like Liquid Hydrogen and Liquid Oxygen, giving 100% efficiency without causing greenhouse gas emissions. This successful test marks a key step towards upgrading LVM3 for future heavy-lift missions.

Notes:
The National Supercomputing Mission (NSM) is a major initiative launched in 2015 by the Government of India to boost High-Performance Computing (HPC) power in the country. It focuses on building supercomputers in India to support research, science, industry, and education using local technology. NSM is jointly led by the Department of Science and Technology (DST) and the Ministry of Electronics and Information Technology (MeitY). It is implemented by the Centre for Development of Advanced Computing (C-DAC), Pune and the Indian Institute of Science (IISc), Bengaluru. The mission aims to reduce dependence on foreign technology and place India among the world’s top supercomputing nations

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:
A new mosquito species called the “Pwani molecular form” has been found in coastal areas of Tanzania and Kenya, drawing global attention to malaria control. It belongs to the Anopheles gambiae complex, which includes some of the world’s most dangerous malaria-spreading mosquitoes. This mosquito shows strong genetic differences from other species in the same group, suggesting unique behaviour or environmental adaptation. Genetic studies confirm it is only found along the coastal regions of East Africa, mainly in Tanzania and Kenya. It does not carry the usual genes for insecticide resistance found in other malaria vectors. This may mean it has a different resistance method or is more sensitive to current insecticides.
