Science & Technology Current Affairs MCQs

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:
India recently launched Donanemab, the country’s first therapy for Alzheimer’s disease. Alzheimer’s disease is a progressive brain disorder and the most common cause of dementia. Dementia involves decline in memory, thinking ability, and behaviour that affects daily life. The disease is associated with ageing, genetics, and lifestyle-related factors.

Notes:
Indian AI warfare company FWDA announced that India’s first AI combat aircraft, Kaal Bhairava, will be manufactured in Portugal in partnership with SKETCHPIXEL. SKETCHPIXEL will provide simulation technologies, AI integration, communication systems, and interoperability support, while FWDA will retain intellectual property rights over the aircraft’s autonomous systems and airframe design. Kaal Bhairava is a medium-altitude long-endurance autonomous combat aircraft with a range of 3,000 km and endurance exceeding 30 hours. The aircraft includes AI-based target recognition, swarm coordination, and encrypted communication systems.

Notes:
Google introduced “information agents” that monitor the web on behalf of users. Information agents are AI-powered assistants integrated with search systems that continuously track websites, updates, listings, and user-defined tasks. These agents perform more effectively when provided with detailed personal information such as location, finances, and user preferences.

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.

Notes:
Google’s biotechnology initiative Project Debug has applied to the United States Environmental Protection Agency to release sterile male mosquitoes in California and Florida. The project aims to biologically control disease-carrying mosquitoes using eco-friendly methods instead of chemical pesticides. The initiative mainly targets mosquito species such as Culex and Aedes aegypti, which spread diseases like West Nile virus, dengue, Zika, and St. Louis encephalitis.

Notes:
Ci2, developed by Fortytwo Labs, became India’s first cryptographic algorithm to receive C-SAFE recognition. Fortytwo Labs is a Pune-based deep-tech cybersecurity company. It is India’s first and only C-SAFE recognized organization. C-SAFE (Cryptographic Security Assessment and Functional Evaluation) is India’s first independent framework for evaluating and certifying cryptographic algorithms. It is awarded by the Data Security Council of India (DSCI).

Notes:
The United States recently activated SOLAR-1, its first dedicated space weather monitoring satellite. It is operated by the National Oceanic and Atmospheric Administration. SOLAR-1 was originally called Space Weather Follow On – Lagrange 1 (SWFO-L1) and later renamed Space Weather Observations at L1 to Advance Readiness–1 (SOLAR-1). Its primary mission is to continuous monitoring of solar activity and space weather to provide early warnings of solar storms.

Notes:
The Jiangmen Underground Neutrino Observatory (JUNO) recently published its first scientific results on neutrino flavour oscillation. JUNO is a large underground neutrino detector located near Kaiping in Guangdong Province, China. The project is an international collaboration involving 74 institutions from Asia, Europe, and America. It is led by the Chinese Academy of Sciences through the Institute of High Energy Physics. JUNO is China’s second neutrino experiment, after the Daya Bay Reactor Neutrino Experiment. Its main scientific objective is to determine the Neutrino Mass Ordering (NMO).

Notes:
India’s first space-tech unicorn, Skyroot Aerospace, has unveiled Vikram-1, the country’s first privately developed orbital rocket at the Satish Dhawan Space Centre in Sriharikota. Vikram-1 is a seven-storey small orbital launch vehicle designed to carry satellites up to 350 kg into low Earth orbit at around 450 km altitude. The rocket is scheduled for its first launch between July 12 and August 4 under “Mission Aagaman”, subject to final tests and approvals. It uses advanced technologies like carbon-composite structures, 3D-printed engines, and in-house propulsion systems to make launches more efficient and cost-effective.
