Palaeofires: Scientists have traced evidence of palaeofires (ancient wildfires) from the Permian Period (~250 million years ago) in the Godavari Basin. The team successfully distinguished between in situ (on-site) and ex situ (transported) charcoal, helping resolve a long-standing debate in geology regarding the origin of charcoal found in coal-bearing formations. Stratigraphic patterns (rock layering) revealed […]

Kerala has demanded changes to the Animal Birth Control: Kerala has demanded changes to the Animal Birth Control (ABC) Rules as increasing stray dog attacks and rabies cases spark public health concerns.The Animal Birth Control (ABC) Rules, 2023, notified under the Prevention of Cruelty to Animals Act, 1960, regulate stray dog population control through sterilisation […]

Inland Waterways Authority of India (IWAI) has signed a strategic MoU with Rhenus Logistics India: The Inland Waterways Authority of India (IWAI) has signed a strategic MoU with Rhenus Logistics India, a global logistics firm, to operate 100 cargo barges and pusher tugs across multiple national waterways, starting in late 2025. This aims to boost […]

Yangtze Finless Porpoise: Scientists use classical poems to map decline of Yangtze finless porpoise from Tang Period to People’s Republic of China.Chinese scientists have utilised classical Chinese poetry to reconstruct the historical distribution of the Yangtze finless porpoise, the only known freshwater porpoise species in the world. This study demonstrates the scientific use of ancient […]

Pulsar G359- Galactic ‘Bone’: Astronomers have identified the likely cause of a fracture in a long, bone-like structure in the Milky Way Galaxy, known as G359.13142-0.20005 (G359.13 or “The Snake”), using data from the Chandra X-ray Observatory and MeerKAT radio array. These galactic “bones” are elongated structures seen primarily in radio waves and aligned with […]

Shear-Wave Splitting: University of Oxford scientists have proposed a new method for monitoring volcanic eruptions using a seismic phenomenon called shear-wave splitting at Mount Ontake, Japan.Shear-wave splitting refers to the phenomenon where seismic shear waves travel at different speeds based on their polarisation, especially when passing through aligned cracks or fractures in rocks. As magma […]

Neanderthal Spear Tip Discovery: An international archaeological team has unearthed the oldest known spear tip in Europe, crafted not by Homo sapiens, but by Neanderthals.The spear tip was discovered in a cave in the North Caucasus region of Russia, embedded in a sediment layer. The findings were published in the Journal of Archaeological Science and […]

India Strengthens Maritime Surveillance with HawkEye 360 Technology Deal: India has taken a significant step in enhancing its maritime security by securing a $131 million deal with the United States for cutting-edge surveillance technology from HawkEye 360. This agreement will provide India with advanced capabilities to detect “dark ships” and improve maritime domain awareness in […]

India has released its first genome-edited rice varieties: India has released its first genome-edited rice varieties namely ‘DRR Dhan 100 (Kamala)’ and ‘Pusa DST Rice 1’ aimed at enhancing yields, climate resilience, and resource efficiency without introducing foreign DNA. They have been developed by ICAR using advanced CRISPR-Cas9 genome-editing technology. No foreign DNA is introduced, […]

Metal-Free Catalyst for Hydrogen Fuel Production: Indian researchers have developed a metal-free catalyst for hydrogen fuel production using mechanical energy, marking a major breakthrough in clean energy innovation.This aligns with India’s National Green Hydrogen Mission and advances sustainable hydrogen technology.Metal-Free Catalyst for Hydrogen Fuel Production is a donor-acceptor covalent organic framework (COF) that functions as […]
