Science & Technology Current Affairs MCQs

Notes:
Jordan recently signed the Artemis Accords at NASA Headquarters, expanding global participation in space governance. The Artemis Accords were launched in 2020 as a non-binding framework for guiding civil space exploration. It was co-led by NASA and the US Department of State along with founding nations like Australia, Japan, and the UK. India is also a signatory, highlighting its role in global space cooperation. The accords promote peaceful exploration and responsible use of outer space.

Notes:
Indian Institute of Tropical Meteorology installed an X-band Doppler Weather Radar at Mahabaleshwar under Mission Mausam. Doppler Weather Radar uses the Doppler Effect to measure velocity and position of atmospheric objects. It emits radio waves; reflected signals from raindrops return to the antenna, helping detect distance and intensity. Time taken for signal return enables tracking of rainfall and cloud movement.

Notes:
A recent multicenter study on Kawasaki Disease evaluated adding Prednisolone to standard treatment. The study found that prednisolone did not reduce the incidence of coronary artery lesions after one month. Kawasaki Disease, also called mucocutaneous lymph node syndrome, is a rare disease causing fever and inflammation of blood vessels. It mainly affects children below 5 years and is more common in boys than girls. The disease was first identified by Tomisaku Kawasaki in 1967 in Japan. It is the most common acquired (not present at birth) heart disease in children in developed countries. The immune system attacks blood vessels, especially coronary arteries, leading to inflammation and swelling.

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.

Notes:
All India Institute of Medical Sciences Delhi has introduced India’s first portable bedside Magnetic Resonance Imaging (MRI) system. Magnetic Resonance Imaging (MRI) is a medical imaging technique that uses strong magnetic fields and radio waves to generate detailed images of internal body structures. MRI is a non-invasive diagnostic method that allows examination of organs, tissues, and the skeletal system without surgery. It provides high-resolution images, helping in accurate diagnosis of various medical conditions. The portable MRI system enables bedside imaging, improving accessibility and critical care management.

Notes:
The NISAR satellite detected rapid land subsidence in Mexico City caused by excessive groundwater extraction. NISAR stands for NASA-ISRO Synthetic Aperture Radar, the first joint Earth observation mission between NASA and ISRO. It will be launched by the GSLV-F16 (GSLV Mk-II) launch vehicle into a sun-synchronous polar orbit. The mission life of the satellite is five years. NISAR is the first satellite to use both L-band and S-band Synthetic Aperture Radar from a single platform. It provides fully polarimetric and interferometric imaging with 240 km swath coverage and revisits Earth every 12 days using SweepSAR technology.

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:
Around 70 cattle recently died in Kendrapada district due to Rumen Fluke Disease, locally called “Kurmi.” Rumen flukes are parasitic worms affecting ruminant animals such as cattle and buffaloes. Adult parasites live in the rumen (stomach), while immature larvae inhabit the small intestine. The disease caused by these parasites is known as paramphistomosis. The disease can be treated using anthelmintic medicines and managed through proper grazing and pasture control.

Notes:
Researchers at Jawaharlal Nehru Centre for Advanced Scientific Research, Bengaluru, developed a novel imaging platform called Cleavable Light-Erased Antibody Reporter. The technology enables visualization and mapping of a large number of proteins within the same biological sample using a single fluorescent marker. CLEAR overcomes major challenges in spatial protein mapping and allows repeated cycles of protein labelling and imaging within the same spectral window. The technology could improve research and diagnosis related to cancer, neurological disorders, immunology, and precision medicine.
