Science & Technology Current Affairs MCQs

Notes:
Scientists at the National Institute of Plant Genome Research (NIPGR), Delhi, have recently used CRISPR-Cas9 gene editing to boost phosphate uptake in japonica rice varieties. CRISPR-Cas9 is a modern gene-editing tool used to precisely modify plant traits. Japonica rice is one of the two major eco-geographical races of Oryza sativa, the other being Indica. It is mainly grown in northern and eastern China, Japan, Korea, Vietnam, and Indonesia. Japonica has short to medium grains, which are thick, sticky, and harder than regular white rice.

Notes:
Recently, Microsoft introduced BioEmu, an advanced Artificial Intelligence (AI) system for simulating protein motion to accelerate drug discovery. The system is officially named Biomolecular Emulator-1 (BioEmu-1). BioEmu-1 is a deep learning model that can generate thousands of protein structures per hour using a single Graphics Processing Unit (GPU). Proteins are vital for biological processes like muscle formation and disease protection. Earlier, predicting protein structures from amino acid sequences was difficult. BioEmu-1 offers deeper insights into protein behavior, which is crucial for developing effective medicines.

Notes:
Recently, the European Space Agency (ESA) launched the INVICTUS research programme. The INVICTUS research program is an initiative of the European Space Agency (ESA), in collaboration with the UK-based Frazer-Nash Consultancy. The goal is to develop hypersonic technologies for future reusable vehicles with horizontal launch capability. It is funded by ESA’s General Support Technology Programme (GSTP) and Technology Development Element (TDE). It will test key technologies for sustained hypersonic flight in Earth’s atmosphere.

Notes:
In July 2025, India launched its first indigenously developed carbon fibre foot prosthesis named ADIDOC. ADIDOC stands for AIIMS Bibinagar – DRDL, DRDO Indigenously Developed Optimised Carbon Foot Prosthesis. It was jointly developed under Atmanirbhar Bharat by AIIMS Bibinagar (under Pradhan Mantri Swasthya Suraksha Yojana, PMSSY) and Defence Research and Development Laboratory (DRDL), Defence Research and Development Organisation (DRDO). The foot is biomechanically tested to bear up to 125 kg load and is designed for K3-level active users. It comes in three weight-based variants to meet individual user needs.

Notes:
Recently, IIT Guwahati researchers developed a bamboo-polymer composite as an eco-friendly alternative to plastic in vehicle interiors. The composite uses Bambusa tulda, a fast-growing bamboo species from Northeast India. It is fused with biodegradable polymers to create a cost-effective and sustainable material. The research was published in the journal Environment, Development and Sustainability. It shows high strength, thermal stability, and low moisture absorption, making it suitable for real-world use.

Notes:
Recently, ISRO is preparing to launch three navigation satellites for the Indian Regional Navigation Satellite System (IRNSS) by next year. Indian Regional Navigation Satellite System (IRNSS), also called Navigation with Indian Constellation (NavIC), is developed by Indian Space Research Organisation (ISRO). It is an independent and fully indigenous satellite navigation system, under India’s full control. Indian Regional Navigation Satellite System (IRNSS) was designed as a 7-satellite constellation to cover India and 1,500 km around it.

Notes:
In July 2025, ISRO announced that the NASA-ISRO NISAR satellite has been mounted on the Geosynchronous Satellite Launch Vehicle (GSLV) ahead of its launch. All systems of the rocket have been successfully checked. NASA-ISRO Synthetic Aperture Radar (NISAR) is a joint mission between the National Aeronautics and Space Administration (NASA) and ISRO to study Earth’s changing ecosystems. GSLV is developed by the Indian Space Research Organisation (ISRO) to launch satellites into Geosynchronous Transfer Orbits (GTOs). It can carry heavier payloads than the Polar Satellite Launch Vehicle (PSLV).

Notes:
Russian President Vladimir Putin recently announced the start of production of the Oreshnik hypersonic missile. Russia plans to deploy the Oreshnik missile in Belarus by the end of 2025. Oreshnik is a Russian intermediate-range hypersonic ballistic missile named after the Russian word for “hazel tree.” It made its operational debut on November 21, 2024, in a precision strike on the Pivdenmash defence facility in Dnipro, Ukraine. The missile is mobile and uses solid fuel, enhancing its rapid deployment capability. It can reach speeds up to Mach 10, which is ten times the speed of sound.

Notes:
Indian Oil Corporation Ltd. (Indian Oil) became the first company in India to secure International Sustainability & Carbon Certification (ISCC) CORSIA for Sustainable Aviation Fuel (SAF) at its Panipat Refinery. The certification is mandatory for commercial SAF production and aligns India with global aviation fuel standards. Certificate was handed over by Cotecna to Indian Oil Chairman A.S. Sahney in New Delhi. ISCC CORSIA, developed under Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) of International Civil Aviation Organization (ICAO), ensures sustainability and lifecycle carbon standards.

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.
