News on Science, Technology and Research in India
Mangrove forests are among the most distinctive coastal ecosystems, developing in intertidal environments where vegetation must tolerate saline water, fluctuating tides and waterlogged soils. Mature mangrove forests often form dense canopies that limit the amount of sunlight reaching the ground, creating conditions in which only certain plant species can establish and survive.
Ammonia is among the most important industrial chemicals used in agriculture because it provides the nitrogen required for manufacturing widely used fertilisers. Nitrogen is essential for plant growth, and ammonia-based fertilisers contribute significantly to agricultural productivity worldwide.
Scientists from the International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), Hyderabad, an autonomous R&D Centre of the Department of Science and Technology (DST) have developed and evaluated two nanocomposite protective coatings—Titanium Aluminium Silicon Nitride (TiAlSiN) and Chromium Aluminium Silicon Nitride (CrAlSiN)—on widely used tungsten carbide cutting tools.
Cosmoserve Space’s Base 1 is a 14,800-square-foot integrated facility designed to support the development, construction, testing and operation of advanced robotic systems for orbital debris removal and in-space satellite servicing. The centre provides specialised infrastructure for engineering systems capable of approaching, interacting with and eventually capturing objects moving through Earth’s orbital environment.
India possesses an extensive cultural and intellectual heritage preserved through manuscripts, inscriptions, regional literature, traditional narratives, historical documents and oral transmission. These materials represent centuries of accumulated knowledge covering language, philosophy, history, science, medicine, astronomy, agriculture, architecture and social traditions.
Encounters between star clusters are relatively uncommon. Detecting a system soon after such an encounter can therefore provide valuable clues about how gravitational interactions influence cluster structure, motion and long-term evolution.
The technology is based on a fundamental principle of fluid mechanics: the distance a liquid travels across a surface depends partly on its viscosity, or resistance to flow. Blood viscosity is influenced by several factors, including the concentration of red blood cells, their mechanical properties and the composition of blood plasma.
The India S&T Scoreboard has been developed to address the fragmentation of scientific and technological information across multiple institutional and statistical sources. Research publications, patent applications, institutional capabilities and innovation infrastructure are often maintained in separate databases, making it difficult to develop an integrated assessment of the research ecosystem at the state level.
Satellite Completes 6,164 Seconds of Engine Firing as India Advances Its Second-Generation NavIC Navigation Programme
Researchers at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), an autonomous institute of the Department of Science and Technology (DST), approached this challenge through topological photonics and demonstrated data transmission at up to 100 gigabits per second (Gbit/s) across an engineered barrier.
