Science & Technology Current Affairs MCQs

Notes:
The Prime Minister praised Indian space startup Digantara for the success of its Mission SCOT. SCOT (Space Camera for Object Tracking) is Digantara’s first mission for space surveillance and one of the world’s first commercial Space Situational Awareness (SSA) satellites. It was launched aboard SpaceX’s Transporter-12 mission and deployed in a sun-synchronous orbit. SCOT is designed to track Resident Space Objects (RSOs) as small as 5 cm in Low Earth Orbit (LEO) with high accuracy and revisit rates. It addresses gaps in existing systems limited by fields of view, weather, and geography.

Notes:
Venus, Saturn, Jupiter, and Mars formed a rare arc in the night sky, called a ‘planet parade.’ A planet parade occurs when multiple planets are visible in the night sky simultaneously. This phenomenon, also known as a conjunction, makes planets appear close together or even touching, though it is a perspective illusion. Planets have unique motions and move at different rates, making simultaneous visibility uncommon. Such alignments involving four or more planets are rare and do not happen annually, as highlighted by NASA.

Notes:
The Central Drugs Standard Control Organisation (CDSCO) has approved Qartemi, a second “living drug,” which is a Chimeric Antigen Receptor (CAR) T-cell therapy designed to treat blood cancer. “Living drugs” involve modifying a patient’s cells and reintroducing them into the body. CAR T-cell therapy is an innovative immunotherapy where T-cells are genetically engineered to target cancer cells. T-cells are extracted from the patient’s blood, modified in the lab by adding a gene for a man-made receptor (CAR), which helps T-cells recognize cancer cells. Modified CAR-T cells are then reintroduced to kill cancer cells.

Notes:
Researchers using NASA’s James Webb Space Telescope and Chandra X-ray Observatory discovered an unusual black hole that might illuminate the development of supermassive black holes. Chandra X-ray Observatory is NASA’s most powerful X-ray telescope, offering eight times greater resolution and detecting sources over 20 times fainter than its previous X-ray telescope. It was launched on July 23, 1999. It is designed to detect X-ray emissions from extremely hot areas in the Universe, including exploded stars, galaxy clusters, and matter near black holes.

Notes:
Scientists detected supersonic winds of 33,000 km/h on the gas giant exoplanet WASP-127b. WASP-127b is located 520 light-years away in the Milky Way and orbits a sun-like star every four days. It is a hot Jupiter, orbiting just 5% of the Earth-Sun distance, with one side always facing its star. Its atmosphere reaches 2,060°F and contains hydrogen, helium, carbon monoxide, and water. WASP-127b is 30% larger than Jupiter but only 16% of its mass, making it extremely puffy. It has the fastest equatorial jet stream winds recorded on any known planet.

Notes:
Chinese researchers developed a new voice-based method for early Alzheimer’s detection. The study was led by Prof. Li Hai at the Hefei Institutes of Physical Science, Chinese Academy of Sciences. Alzheimer’s disease is a brain condition that causes memory loss and cognitive decline. It affects thinking, learning, and organizing skills over time. It is the most common type of dementia, making up 60-80% of cases. The disease impacts brain regions responsible for thought, memory, and language.

Notes:
Union Minister Dr. Jitendra Singh inaugurated India’s first indigenous Automated Biomedical Waste Treatment Plant, “Srjanam,” at AIIMS New Delhi. It was developed by the Council of Scientific and Industrial Research – National Institute for Interdisciplinary Science and Technology (CSIR-NIIST). It has an initial capacity of 400 kg/day and can process 10 kg of degradable medical waste daily. India generates 743 tonnes of biomedical waste daily, posing health risks. “Sṛjanam” is validated for antimicrobial effectiveness and is safer than organic fertilizers.

Notes:
IIT-Madras and ISRO developed and successfully booted the SHAKTI-based semiconductor chip, IRIS (Indigenous RISCV Controller for Space Applications). SHAKTI systems use RISC-V (reduced instruction set computer five), an open-source Instruction Set Architecture (ISA), for custom processor design. The project is backed by the Ministry of Electronics and IT under the Digital India RISC-V (DIRV) initiative. The goal is to promote indigenous microprocessor-based products with top security and transparency. IRIS is a significant step toward India’s self-reliance in semiconductor technology, especially for space applications.

Notes:
Uganda and WHO confirmed an outbreak of Sudan Virus Disease (SVD). It is a viral hemorrhagic fever, related to Ebola, caused by the Sudan virus (SUDV). It was first identified in Sudan in 1976. It exists in animal reservoirs in the region. It has a high fatality rate and spreads through direct contact with bodily fluids or contaminated surfaces. Symptoms start with fever, fatigue, and sore throat, followed by vomiting, diarrhea, rash, and bleeding. There are no approved treatments or vaccines, but early supportive care improves survival chances.

Notes:
Russia has developed an mRNA-based personalized cancer vaccine, set for free distribution by early 2025. mRNA vaccines provide genetic instructions to help the body produce antigens that trigger an immune response. Unlike traditional vaccines, this is not preventive but treats existing cancer by targeting tumor-specific antigens. It trains the immune system to attack cancer cells by producing proteins similar to tumor antigens.
