Science & Technology Current Affairs MCQs

Notes:
Andhra Pradesh Chief Minister N Chandrababu Naidu laid the foundation stone for the Google Cloud India AI Hub in Visakhapatnam. The project is part of a major collaboration involving Google Cloud, Adani Group, and Bharti Airtel. Google has committed an investment of USD 15 billion, making it one of India’s largest foreign direct investments. The AI data centre will have a capacity of 1 Gigawatt and will be built over 600 acres. It will enhance India’s artificial intelligence, cloud computing, and digital infrastructure.

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:
CSIR-Central Road Research Institute and Bharat Petroleum Corporation Limited were recognized by the India Book of Records and Asia Book of Records for constructing the first roadblock section using technical textile geocells made from end-of-life plastic waste. The project demonstrated the scientific use of difficult-to-manage plastic waste in sustainable road infrastructure development. The technology uses technical textile geocells manufactured from processed end-of-life plastic waste for road engineering applications. The initiative supports sustainable waste management, resilient road construction, and circular economy goals.

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:
Department of Biotechnology organised the UMMID event in New Delhi. UMMID stands for “Unique Methods of Management of Inherited Disorders” and focuses on diagnosis, counselling, screening, and management of rare genetic diseases. The programme aims to promote genome-based, precision-driven, and personalised healthcare in India. It was launched by the Department of Biotechnology to improve access to genetic diagnostics and treatment for inherited disorders. During the event, the UMMID Compendium and UMMID Dashboard were also launched to strengthen monitoring, diagnostics, and outreach. The initiative has benefited nearly three lakh individuals and established around 30 NIDAN Kendras for advanced diagnostics and counselling.

Notes:
A recent study by All India Institute of Medical Sciences Bhopal highlighted the need for early and advanced health screening in children affected by Sickle Cell Disease. Sickle Cell Disease is a group of inherited blood disorders that affect haemoglobin in red blood cells. The most severe and common form of the disease is sickle cell anaemia. The disease is inherited genetically when a child receives sickle cell genes from both parents. Treatments include symptom management, bone marrow transplant, and emerging gene therapy approaches.

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.

Notes:
Scientists from the Agharkar Research Institute, Pune, have developed a gene-silencing strategy for effective tumor inhibition in breast cancer. The institute functions under the Department of Science and Technology (DST). Researchers developed a biodegradable nanocarrier platform for targeted gene therapy in breast cancer. The technology uses mesoporous silica nanoparticles to deliver small interfering RNA (siRNA) molecules that silence disease-causing genes. The nanocarrier is functionalized with a protamine biopolymer and an MUC1-specific aptamer for precise targeting of breast cancer cells.

Notes:
Recently, explosions and boom sounds heard in Boston were suspected to have been caused by a bolide entering the atmosphere. A bolide is a large, exceptionally bright meteor that often explodes in the upper atmosphere. It produces a brilliant flash of light and may generate loud sonic booms. Bolides are brighter and more dramatic than ordinary meteors, and sometimes their fragments reach the ground as meteorites. Studying bolides helps scientists understand the composition and behavior of meteoroids during atmospheric entry.

Notes:
NASA officially ended the MAVEN (Mars Atmosphere and Volatile Evolution) mission after permanently losing contact with the spacecraft. MAVEN was launched in November 2013 and operated around Mars for more than 11 years, far exceeding its original one-year mission. The spacecraft became unrecoverable after an unexpected loss of signal in December 2025. MAVEN helped scientists understand how solar wind and radiation stripped away Mars’ atmosphere, transforming it from a warmer, wetter planet into the cold, dry world seen today.
