Science & Technology Current Affairs MCQs

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:
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:
Kerala Agricultural University (KAU) has released a new green chilli variety called KAU Thejaswini. The variety has been developed to promote chemical-free backyard and kitchen gardening. It was developed by the Department of Vegetable Science, College of Agriculture, Vellayani. It starts yielding chillies within 2 months of sowing. The variety was approved by the 30th State Seed Sub-Committee.

Notes:
Narayana Health City, Bengaluru, recently performed India’s first Pulsed Field Ablation (PFA) procedure for the treatment of Atrial Fibrillation (AFib). PFA is an advanced cardiac electrophysiology technique that uses ultra-fast electrical pulses to selectively target abnormal heart tissue while minimizing damage to surrounding structures. The procedure was completed in 35 minutes, significantly faster than traditional thermal ablation methods that can take several hours. Atrial Fibrillation (AFib) is a common heart rhythm disorder in which the upper chambers of the heart beat irregularly, increasing the risk of stroke, heart failure, and other complications.

Notes:
Scientists discovered the world’s largest whale graveyard in the Diamantina Fracture Zone. The site lies in the southeastern Indian Ocean at depths of more than 7,000 metres. The discovery was led by the Chinese Academy of Sciences using the Fendouzhe submersible. Researchers identified more than 485 fossil sites spread across a 1,200-km underwater rift. The fossils are estimated to be 120,000 years to 5.3 million years old. This is considered a landmark discovery in marine paleontology.

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:
Recently, scientists at the Institute of Nano Science and Technology (INST), Mohali, developed a novel electrolyte additive called BDIM to improve the performance of Aqueous Zinc-Ion Batteries (AZIBs). Aqueous Zinc-Ion Batteries (AZIBs) are considered a safer, cheaper, and more environmentally friendly alternative to lithium-ion batteries. The newly developed additive BDIM (1,3-bis(1,3-dicarboxypropyl)-1H-imidazole-3-ium chloride) improves battery durability through interface engineering rather than expensive material redesign. BDIM suppresses hydrogen evolution, corrosion, and zinc dendrite growth by preventing water-induced side reactions at the zinc surface.

Notes:
Astronomers using the Murchison Widefield Array (MWA) have discovered a new millisecond pulsar. The discovery is part of the ongoing Southern-sky MWA Rapid Two-metre (SMART) survey. The MWA is a low-frequency radio telescope located at the Murchison Radio-astronomy Observatory (MRO), Western Australia. It is also a key precursor site for the future Square Kilometre Array (SKA) project. The telescope is a collaboration of 20 research institutions across five countries: Australia, Canada, China, Japan, and the United States. It is led by Curtin University, Australia.

Notes:
Recently, researchers at Indian Institute of Technology Delhi studied rutile oxides and found a significant difference between metals and insulators that could not be explained by an existing mathematical model. Rutile is a mineral composed mainly of titanium dioxide (TiO₂) and is the most common and stable form of titanium dioxide in nature. It is one of the three principal titanium minerals, along with ilmenite and leucoxene. Rutile occurs in igneous, metamorphic, and sedimentary rocks and is commonly mined from heavy mineral sands. In India, major rutile deposits are found in the coastal sands of Kerala, Tamil Nadu, Odisha, and Andhra Pradesh.

Notes:
Recently, Lightstorm, along with Microsoft, Singtel, and Tata Communications, launched the India–Southeast Asia (I-2SEA) Submarine Cable System. It is a 3,600-km optical fibre subsea cable connecting India’s east coast with Singapore and Malaysia. The project is expected to be Ready for Service (RFS) by Q4 2029. It is designed to support AI infrastructure, cloud services, and high-capacity digital connectivity between India and Southeast Asia.
