Science & Technology Current Affairs MCQs

Notes:
On July 14, 2025, Israel launched its first fully government-funded and domestically built communications satellite, Dror-1, from Cape Canaveral, Florida aboard a SpaceX Falcon 9 rocket. Dror-1 is Israel’s most advanced geostationary satellite, built 100% with local technologies to ensure strategic independence. It weighs 4.5 tonnes, spans 17.8 metres, and will serve Israel’s communication needs for the next 15 years. The satellite orbits 36,000 km above Earth, maintaining constant coverage over Israel and nearby regions.

Notes:
Recently, astronomers observed rocky planet formation for the first time by detecting minerals condensing from vapor around a young star named HOPS‑315. HOPS‑315 is a newborn protostar located 1,300 light-years away in the Orion molecular cloud. It has a rotating protoplanetary disc of gas and dust, tilted in a way that allows Earth-based telescopes to view its inner region clearly. This rare view helped scientists directly witness the earliest stages of rocky planet formation. The minerals found—like forsterite and enstatite—match those in chondritic meteorites on Earth. This discovery closely mirrors how our own Solar System may have formed.

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:
Recently, Bengaluru-based space company Protoplanet launched the Human Outer Planetary Exploration (HOPE) station in Ladakh’s Tso Kar region. HOPE is a moon and Mars simulation research station mimicking off-Earth terrain and environment. It is located in the high-altitude cold desert of Tso Kar basin, Ladakh. The project is developed by Protoplanet with technical and financial support from Indian Space Research Organisation (ISRO). It aims to study human psychological, physiological, and epigenetic responses in extreme isolation. It supports India’s long-term space goals including a crewed lunar mission by 2040 and a space station by 2035.

Notes:
Recently, a new blood group named CRIB was discovered in a South Indian woman from Kolar district, Karnataka. The discovery was announced at the 35th Regional Congress of the International Society of Blood Transfusion (ISBT) held in Milan, Italy. CRIB stands for Cromer India Bangalore and is part of the Cromer (CR) blood group system. This blood group was previously unidentified anywhere in the world. The discovery took 10 months of research and molecular testing by international experts.

Notes:
Recently, IIT Roorkee developed a new drug candidate, Compound 3b, to fight deadly drug-resistant bacteria. It targets KPC-2-producing Klebsiella pneumoniae, a World Health Organization (WHO) top-priority superbug. Compound 3b is a β-lactamase inhibitor that stops bacterial enzymes from breaking down antibiotics. It works with the antibiotic Meropenem, restoring its effectiveness against resistant infections. Preclinical lab and animal tests showed major infection reduction in lungs and safety to human cells. It marks a major step against antimicrobial resistance and boosts India’s role in global biomedical research.

Notes:
NASA announced that the James Webb Space Telescope (JWST) discovered a new 29th satellite of Uranus, named S/2025 U1. The moon has an estimated diameter of 10 kilometres and orbits Uranus at a distance of about 56,000 kilometres. S/2025 U1 will receive an official name from the International Astronomical Union (IAU) in the future. Uranus is the seventh planet from the Sun and the third-largest planet in the solar system. Uranus is an ice giant, composed mainly of hydrogen, helium, water, methane, and ammonia. Uranus now has 29 moons, with five major moons: Miranda, Ariel, Umbriel, Titania, and Oberon.

Notes:
On 21 August 2025, the Indian Council of Medical Research (ICMR) launched CEREBO, a portable non-invasive device to detect traumatic brain injuries (TBI). It uses near-infrared spectroscopy with machine learning to identify intracranial bleeding and edema within one minute, giving colour-coded, radiation-free results. The device is safe for infants and pregnant women and can be operated by paramedics or unskilled staff with just 30 minutes of training. It was developed by ICMR, AIIMS Bhopal, NIMHANS Bengaluru and Bioscan Research. India records over 1 lakh deaths and 10 lakh serious head injuries annually, making early TBI detection critical.

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:
Indian Institute of Technology Hyderabad (IIT Hyderabad) signed a Memorandum of Understanding (MoU) with Army Training Command (ATC), Shimla. The partnership establishes a Centre of Excellence (CoE) named VIGRAHA (Virtual, Intelligent, Ground-breaking Research in AR/VR and High-tech Applications for Indian Army). The Simulator Development Division (SDD), Secunderabad represents the Indian Army in this collaboration. The CoE will focus on Augmented Reality (AR), Virtual Reality (VR), Artificial Intelligence (AI), Robotics, unmanned systems, and emerging defense technologies. The initiative strengthens India’s self-reliance (Atmanirbhar Bharat) in defense technologies.
