Science & Technology Current Affairs MCQs

Notes:
Asteroid 2024 YR4 was recently confirmed by NASA to not collide with the Moon in 2032. It is an Apollo-type asteroid, meaning its orbit crosses Earth’s orbit but remains mostly outside it. It was discovered in 2024 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile. In its name, Y indicates discovery in the second half of December, while R4 shows it was the 117th asteroid identified in that period. It is a Near-Earth Object (NEO) with size about 174–220 feet (53–67 metres). It likely originated from the central Main Asteroid Belt between Mars and Jupiter.

Notes:
A pilot plant for manufacturing Nd-Fe-B (Neodymium-Iron-Boron) rare earth permanent magnets has been established at International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad, under the Department of Science and Technology (DST). The facility adopts an end-to-end “mineral-to-market” approach, covering processes from strip-cast alloy production to finished sintered magnets, enabling a self-reliant manufacturing ecosystem. Nd-Fe-B magnets are critical components used in electric vehicles, renewable energy systems, electronics, and advanced manufacturing technologies. The initiative aims to reduce import dependence, address global supply chain vulnerabilities, and strengthen India’s position in the global rare earth value chain.

Notes:
U.S. drugmaker Pfizer and France’s Valneva reported that their experimental Lyme disease vaccine showed over 70% efficacy in a late-stage trial. Lyme disease, or Lyme borreliosis, is caused by the bacteria Borrelia burgdorferi. It affects the skin, nervous system, heart, and joints. The disease is named after Lyme, Connecticut, United States, where it was first identified in children in 1976. Lyme disease is common in North America, Europe, and parts of Asia. It is transmitted to humans through deer ticks (black-legged ticks) found in grassy, wooded, or bushy areas. Not all tick bites cause Lyme disease, and it cannot spread between humans or from pets.

Notes:
NASA is set to launch the Artemis II mission, which is part of its broader lunar exploration programme. Artemis II is a key mission under the Artemis programme, aimed at returning humans to the Moon in a sustained and strategic manner. The mission will send four astronauts on a crewed journey around the Moon, marking a major step in human space exploration. It is part of efforts to establish a long-term human presence on the Moon. The mission views the Moon as a platform for deeper space exploration, including future missions to Mars and beyond.

Notes:
Bharat Aluminium Company Limited, a unit of Vedanta Aluminium, has deployed ALAISA (Aluminium AI Support Agent: Artificial Intelligence-based assistant for industrial support). ALAISA is a humanoid, AI-powered assistant designed to enhance shop-floor efficiency, safety, and workforce capability. It is operational at BALCO’s Chhattisgarh smelter and acts as a real-time training and decision-support interface. It provides guidance on SOPs (Standard Operating Procedures: step-by-step work instructions), SMPs (Standard Maintenance Practices), and safety protocols.

Notes:
Institute of Nano-Science and Technology, Mohali, developed a new material to detect nicotine and cotinine using fluorometric sensing. Fluorometric sensing is a technique that measures substances through fluorescent emission. The material “lights up” on contact with nicotine/cotinine, enabling quick detection. It is based on Iron-based Metal-Organic Framework (Fe-MOF), a nano-structured porous material. It detects even small amounts accurately, improving over traditional methods. The material is biocompatible (safe for living cells) and works at in-vitro stage.

Notes:
Recently, the Curiosity rover of NASA detected a mix of organic molecules on Mars, strengthening evidence about the planet’s past habitability. The Curiosity rover mission was launched by the National Aeronautics and Space Administration (NASA). It was launched on November 26, 2011, the rover is a key component of the Mars Science Laboratory (MSL) mission to study Gale Crater on Mars. Its objectives include studying whether life ever existed, understanding Mars’ climate and geology, and preparing for future human missions.

Notes:
Recently, Rocklink India Pvt. Ltd. set up an integrated recycling facility in Sikandrabad UPSIDC Industrial Area, Uttar Pradesh. The plant focuses on recycling lithium-ion batteries, rare earth magnets, and metal-bearing industrial waste. It has a capacity of 10,000 tonnes/year for lithium-ion batteries and 60 tonnes/month for rare-earth magnets. A rare-earth chloride processing unit (1,500 tonnes/year) is planned for 2026. The initiative supports domestic recovery of critical minerals and promotes a circular economy.

Notes:
A tigress and four cubs died in Kanha Tiger Reserve, raising concern over Canine Distemper. It is a highly contagious disease caused by Canine Distemper Virus (CDV) affecting respiratory, gastrointestinal, and nervous systems. It mainly infects dogs, especially unvaccinated ones and puppies below four months. CDV is a multi-host pathogen affecting wildlife such as carnivores, big cats, marine mammals, and primates. Transmission occurs through direct contact or airborne exposure. Infected animals can shed the virus for months despite low environmental survival. There is no specific cure or antiviral treatment available. Vaccination is the most effective preventive measure.

Notes:
South Korea has launched the Compact Advanced Satellite 500-2 (CAS500-2) on May 3, 2026. The satellite is an Earth-observation satellite also known as Next-Generation Medium Satellite No. 2. It was launched aboard Falcon 9 from Vandenberg Space Force Base in the United States. The mission was overseen by the Korea AeroSpace Administration. The launch was delayed for nearly four years due to changes from the Russia-Ukraine conflict. The satellite entered a sun-synchronous orbit at an altitude of about 498 kilometres. It successfully established communication with a ground station in Svalbard shortly after launch.
