Science & Technology Current Affairs MCQs

Notes:
Recently, National Aeronautics and Space Administration unveiled the Nancy Grace Roman Space Telescope. It is a wide-field space observatory designed to survey large regions of the universe and detect exoplanets. It will study dark matter and dark energy, which together make up about 95% of the universe. The telescope is named after Nancy Grace Roman, known as the “mother of the Hubble Space Telescope.” It costs about USD 4 billion and will be placed 1.5 million km from Earth.

Notes:
GalaxEye has successfully launched Mission Drishti, the world’s first OptoSAR satellite. The satellite was launched aboard Falcon 9 from California, United States. Mission Drishti weighs about 190 kilograms and is the largest Earth observation satellite built by a private Indian company. It combines optical and Synthetic Aperture Radar (SAR) technology for all-weather, day-and-night imaging. The mission enhances India’s capabilities in Earth observation and strategic monitoring.

Notes:
Scientists have warned that rising temperatures due to climate change may increase the spread of the Brain-Eating Amoeba, scientifically known as Naegleria fowleri. The amoeba is commonly found in warm freshwater bodies such as lakes, rivers, ponds, hot springs, and moist soil. It enters the human body through the nose and attacks brain tissues. Infection by Naegleria fowleri causes Primary Amebic Meningoencephalitis (PAM), a rare but highly fatal disease of the central nervous system. Higher temperatures create favourable conditions for the amoeba’s growth and survival. The warning highlights the possible health impacts of climate change on infectious diseases.

Notes:
South Korea introduced its first humanoid robot monk named Gabi at a Buddhist ceremony held at Jogyesa Temple on 6 May 2026. Gabi was presented by the Jogye Order ahead of Buddha’s Birthday celebrations on 24 May 2026. A humanoid robot is a machine designed with a human-like body structure, including a head, torso, arms, and legs. During the ceremony, Gabi bowed to monks, pledged devotion to Buddhism, and received the Dharma name “Gabi,” combining Siddhartha and the Korean word for mercy.

Notes:
Valley fever recently came into news after a 37-year-old Indian tech professional in California died due to severe lung complications and respiratory failure caused by the infection. Also known as acute coccidioidomycosis, it is a fungal disease caused by Coccidioides fungi found in dry, dusty soil of the southwestern United States, Mexico, and parts of Central and South America. Infection occurs by inhaling airborne fungal spores disturbed through farming, construction, or wind; it does not spread from person to person. Treatment involves antifungal medicines, while no vaccine is currently available.

Notes:
Dhruva Space secured ₹105 crore under the Research, Development & Innovation Fund for “Project Garud.” Project Garud is a satellite platform programme focused on developing a flat-pack 500 kg-class satellite platform for scalable and high-volume manufacturing. The project aims to bridge the gap between small experimental satellites and large traditional spacecraft systems. The platform is designed for applications in telecommunications, national security, Earth observation, and data-driven services. Its flat-pack architecture enables efficient launch stacking, faster integration, and quicker deployment timelines.

Notes:
Scientists from the Institute of Nano Science and Technology developed an ultrathin flexible film embedded with nano-gold particles that converts small temperature changes into electrical signals. The research was supported by the Department of Science and Technology. The film is based on polyvinylidene fluoride (PVDF), a flexible polymer used in sensing and electronics. Tiny hexagonal gold nanoparticles improved the material’s pyroelectric performance, enabling efficient thermal-to-electrical energy conversion. The technology could be used in wearable electronics, self-powered sensors, smart photodetectors, and low-power healthcare devices.

Notes:
Another tiger was recently found dead in Kanha Tiger Reserve, raising concerns over possible Canine Distemper infections among wild animals. Canine Distemper is a highly contagious viral disease caused by the Canine Distemper Virus (CDV), a single-stranded RNA virus of the Paramyxoviridae family. The disease affects dogs, foxes, wolves, raccoons, felines, and several wildlife species, but it does not infect humans. It spreads through droplets, direct contact, and infected body fluids such as saliva, urine, and feces. There is no specific cure for CDV; vaccination, hygiene, and isolation remain the best preventive measures.

Notes:
Indian Space Research Organisation developed the Environmental Control and Life Support System for the Gaganyaan mission. The ECLSS is a mission-critical system designed to recreate Earth-like sea-level conditions inside a spacecraft for astronauts in low Earth orbit. The system regulates cabin air composition, atmospheric pressure, temperature, humidity, and waste management to ensure astronaut safety and comfort.

Notes:
Geologists discovered a rare microscopic sunflower-shaped form of Pyrite in lignite coal reserves of Gujarat. Pyrite is a naturally occurring iron disulfide mineral. It is commonly known as “fool’s gold” because of its resemblance to gold. Pyrite has a brass-yellow colour and metallic lustre. Its name comes from the Greek word pyr meaning “fire,” as it produces sparks when struck with metal. Pyrite occurs in igneous, sedimentary, and metamorphic rocks, hydrothermal deposits, coal beds, and even fossils.
