Science & Technology Current Affairs MCQs

Notes:
The National Supercomputing Mission (NSM) was launched in April 2015 by the Government of India with a budget of Rs.4,500 crore. Its vision is to achieve self-reliance and global leadership in supercomputing and provide state-of-the-art facilities to researchers. It is jointly implemented by the Ministry of Electronics and Information Technology (MeitY) and the Department of Science and Technology (DST) through Centre for Development of Advanced Computing (C-DAC), Pune and Indian Institute of Science (IISc), Bengaluru. As of August 2025, 37 supercomputers with 40 Petaflops capacity are installed across IITs, IISc, R&D labs and Tier-II/III cities. This information was submitted in the Lok Sabha today by Shri Jitin Prasada, Minister of State for Electronics and Information Technology.

Notes:
Huntington’s Disease (HD) is not yet included in the rare disease category under the National Policy for Rare Diseases despite demands from patients and caregivers in 2024. It is a genetic condition that affects brain cells, causing them to slowly lose function and die. It is inherited, with a 50% chance of passing from an affected parent to a child. It impacts brain regions controlling voluntary movement, memory, thinking, and decision-making, including the basal ganglia and cortex.

Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, are developing a nanotechnology-based tool for early detection of Parkinson’s Disease (PD). Parkinson’s Disease (PD) is a rapidly growing neurological disorder in India, often diagnosed after significant neurodegeneration. The team focused on α-synuclein, a protein that changes from harmless to toxic forms, damaging brain cells. They created gold nanoclusters (AuNCs), ultrasmall particles coated with amino acids to selectively bind normal or toxic protein forms. The tool enables early-stage detection, improving treatment, quality of life, and reducing healthcare costs.

Notes:
Israeli defense technology firm Elbit Systems recently launched its advanced JUPITER space camera aboard the National Advanced Optical System (NAOS) satellite. The satellite was launched from Vandenberg Space Force Base, California, on a SpaceX Falcon 9 rocket. JUPITER supports military operations, environmental monitoring, scientific research, and wide-span observation missions. It features a large aperture, lightweight design, high-resolution panchromatic channel for black-and-white imaging, and a Near Infrared (NIR) channel for vegetation, water, and material analysis. The camera can capture continuous long image strips covering large areas efficiently.

Notes:
Scientists at Raman Research Institute (RRI) proposed a mission called PRATUSH to study the Cosmic Dawn. PRATUSH stands for Probing ReionizATion of the Universe using Signal from Hydrogen. It is a radio telescope to be placed on the far side of the Moon. It is built by Raman Research Institute (RRI) Bengaluru with collaboration from Indian Space Research Organisation (ISRO). It will use a wideband antenna (30–250 MHz), a self-calibratable analog receiver, and a digital correlator with 100 kHz spectral resolution. It will observe large sky regions continuously and record spectra of radio emission. Its nominal lifetime is two years to collect high-quality data.

Notes:
India’s largest Lithium-ion (Li-ion) battery manufacturing plant was inaugurated in Haryana on 5 September 2025. When fully operational, it will produce 20 crore battery packs annually, meeting nearly 40% of India’s 50 crore pack requirement. The plant was set up under the Centre’s Electronics Manufacturing Cluster (EMC) scheme. Li-ion batteries are rechargeable, with lithium ions moving between graphite (negative electrode) and lithium metal oxides (positive electrode) through a non-aqueous electrolyte. They offer high energy density (75-200 Wh/kg), are lightweight, use fewer toxic metals, and provide good cycle stability and efficiency. They have low self-discharge and no memory effect, ensuring reliable performance.

Notes:
Russia has launched EnteroMix, a new mRNA-based cancer vaccine, reported to show 100 percent efficacy in early trials. It was developed by the National Medical Research Radiology Centre (NMRRC) and Engelhardt Institute of Molecular Biology under the Russian Academy of Sciences. The launch took place at the St Petersburg International Economic Forum (SPIEF 2025) and shared globally via Sputnik news service. The vaccine targets colorectal cancer first, with versions in development for glioblastoma and melanoma. EnteroMix uses four harmless viruses to attack cancer cells and boost immune defence. Russian Federal Medical and Biological Agency (FMBA) confirmed its safety for repeated use and personalised RNA-based tailoring.

Notes:
A study of fossil leaves from Nagaland revealed how Antarctica influenced the Indian Monsoons. Fossil leaves from the Laisong Formation in Nagaland revealed that the region once had a warm and wet climate with very high rainfall and temperatures. The fossils matched the period when massive ice sheets began forming in Antarctica, showing a global connection. Growth of Antarctic ice reshaped global wind and rainfall patterns by shifting the Intertropical Convergence Zone (ITCZ) toward the tropics. This shift brought intense monsoonal rains to Northeast India and led to the evolution of the monsoon system. The research used CLAMP (Climate Leaf Analysis Multivariate Program) method to analyze fossil leaves. CLAMP treats fossil leaves as “climate fingerprints” to reconstruct past climates.

Notes:
Scientists at the University of Tasmania, Australia, developed a portable ion chromatograph called Aquamonitrix to perform ion separation in the field. The device was tested by undergraduate students who analysed soil pore water for harmful nitrate and nitrite ions immediately after collection. Results were comparable to expensive lab-based chromatographs, proving accuracy with lower cost and time. Aquamonitrix uses sodium chloride solution and a UV absorbance detector, making it simple, eco-friendly, and effective. The portable device costs about 10,000 versus 100,000 for conventional lab instruments. It provides hands-on field experience for students, linking theory with real-world environmental analysis.

Notes:
Mosquito-borne diseases like dengue fever are rising due to rapid urbanisation, climate change, and global travel. A new study published on 3 September in Science Translational Medicine shows waning immunity against Japanese Encephalitis Virus (JEV) can worsen dengue outcomes. Japanese Encephalitis (JE) is a viral zoonotic disease caused by the Japanese Encephalitis (B) virus. Transmission occurs through infected Culex mosquitoes of the Vishnui group, not from human to human. It is most common in rural Asia, especially during monsoon seasons. Both viruses belong to the genus Orthoflavivirus and show cross-immune interactions.
