Science & Technology Current Affairs MCQs

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:
Scientists recently developed a new technique called Light-microscopy-based Connectomics (LICONN) to map brain cell connections using light microscopes. LICONN was developed at the Institute of Science and Technology Austria (ISTA). It allows mapping of brain’s complex neural networks at the nanoscale and also identifies specific molecules in those connections. LICONN combines light microscopy with hydrogel expansion, fluorescent stains, artificial intelligence (AI), and analytical methods. Brain tissue is soaked in a special gel that expands it 16 times, making tiny structures visible under light microscopes. It is the first method after electron microscopy (EM) that can reconstruct all synaptic connections between neurons.

Notes:
A recent study in Nature Geoscience found that soil microbes, particularly fungi and bacteria, play a central role in regulating phosphorus availability and cycling over a span of 700,000 years in the Cooloola coastal dune system. These microbes manage the release and transformation of phosphorus in nutrient-poor soils, acting as crucial “gatekeepers” in ecosystem nutrient dynamics. These microbes adapt by replacing phospholipids with non-phosphorus lipids and storing fats to reduce phosphorus demand. They also improve phosphorus use efficiency in their metabolism to survive in low-phosphorus soils. Microbes both compete with plants for phosphorus and help them by recycling it and improving access.

Notes:
Denmark has inaugurated the world’s first large-scale commercial e-methanol facility in Kasso, southern Denmark. It has a production capacity of 42,000 metric tons (53 million litres) of e-methanol annually. E-methanol offers a viable path for reducing emissions in sectors like shipping and chemical manufacturing. E-methanol is produced by combining green hydrogen with captured carbon dioxide.

Notes:
The recent approval by the United States to sell AIM-120C-8 Advanced Medium-Range Air-to-Air Missiles (AMRAAMs) to Turkey has raised serious concerns in India due to changing regional security dynamics. AIM-120C-8 Advanced Medium-Range Air-to-Air Missile (AMRAAM) is a state-of-the-art missile with beyond-visual-range air-to-air missile (BVRAAM) and surface-to-air missile (SAM) capabilities. It is developed by Raytheon Technologies, a top US defence company. The missile is designed to engage and destroy enemy aircraft at long distances before visual contact is made. It is a key component in modern air combat systems and significantly boosts the air power of its users.

Notes:
The Indian Space Research Organisation (ISRO) launched the PSLV-C61 mission from Sriharikota to place the EOS-09 satellite into a Sun-synchronous polar orbit. The mission failed due to a problem in the third stage. PSLV stands for Polar Satellite Launch Vehicle, a four-stage rocket designed by ISRO. It mainly places satellites into Sun-synchronous polar orbits, ideal for Earth observation. The PSLV uses alternating solid and liquid propulsion stages for precision. The first stage uses HTPB-based solid fuel with six strap-on boosters in XL version, producing 4.8 MegaNewtons (MN) thrust. The second stage runs on liquid fuel, with the Vikas engine using Unsymmetrical Dimethylhydrazine (UDMH) and Nitrogen Tetroxide (N₂O₄), generating about 8 MN thrust. The third stage uses solid HTPB fuel again. The fourth stage has two liquid engines burning Monomethylhydrazine (MMH) and Mixed Oxides of Nitrogen (MON).

Notes:
On May 19, 2025, the World Health Organization (WHO) honoured Austria, Norway, Oman, and Singapore for eliminating industrially produced trans fats from their national food supply. The announcement was made at the 78th World Health Assembly in Geneva, Switzerland. Trans fats, also called trans-fatty acids (TFA), are harmful unsaturated fats linked to over 278,000 deaths each year. WHO launched the global goal in 2018 to eliminate trans fats by 2025, but progress remains slow. By May 2025, 60 countries had adopted best-practice policies, covering only 46% of the global population. India implemented such a policy in 2022 through the Food Safety and Standards (Prohibition and Restrictions on Sales) Second Amendment Regulations, 2021. India is among the leading Asian countries in enforcing best-practice policies, alongside Thailand.

Notes:
On May 23, 2025, Chennai-based startup Agnikul Cosmos successfully test-fired India’s first electric motor-driven semi-cryogenic engine. This marks a major step for private players in advancing Indian space technology. The engine uses electric motors instead of traditional gas generators to power fuel pumps, allowing precise thrust control and quick response. It runs on semi-cryogenic propulsion using liquid oxygen (LOX) and refined kerosene, balancing performance and cost. This innovation boosts engine reliability and suits future sub-orbital missions.

Notes:
Scientists at Raman Research Institute (RRI), Bengaluru, under the Department of Science and Technology, have found a new method to detect topological invariants in quantum materials using the spectral function. The spectral function is a quantum tool that shows how energy and particles like electrons behave inside a material. It is commonly used to study electronic structure such as density of states and dispersion relations. The team focused on momentum-space spectral function (SPSF), which acts like a quantum fingerprint showing how electrons are spread across energy and momentum. This method reveals hidden topological features using values like winding numbers in one-dimensional systems and Chern numbers in two-dimensional systems.

Notes:
Researchers at Sher-e-Kashmir University of Agricultural Sciences and Technology (SKUAST) have created India’s first gene-edited sheep. This is a major breakthrough in animal biotechnology and marks a historic achievement for India. The sheep was developed using genome editing without adding any foreign Deoxyribonucleic Acid (DNA), making it different from transgenic animals. This innovation may ease regulatory approvals under India’s updated biotechnology policy. It positions SKUAST-Kashmir as a leader in reproductive biotechnology research. This recent development places India among the global frontrunners in advanced genome editing technologies.
