At the heart of their system is a composite siphon: a fabric wick paired with a grooved metallic surface. The fabric draws salty water from a reservoir, while gravity ensures a smooth, continuous flow. Instead of allowing salt to crystallize, the siphon flushes it away before buildup occurs.
Marine fish stock assessment studies in Indian waters showed that the stocks are in good health and 91.1% of the 135 fish stocks assessed in different regions during 2022 were found sustainable.
Introducing a special discussion on “Critical Role of the Space Programme for Viksit Bharat by 2047” in the Lok Sabha today, Dr. Jitendra Singh underlined that Group Captain Shubhanshu Shukla’s mission was not just a symbolic triumph but also a demonstration of India’s growing capability in cost-effective space technology, international collaboration, and indigenous innovation.
Researchers at the School of Physics, IISER Thiruvananthapuram have been on the lookout for a sensor that could detect hydrogen at room temperature, even in trace quantities. The Project was supported by the Nano mission program of the Department of Science and Technology (DST).
MATSYA-6000—a first-of-its-kind, fourth-generation scientific submersible—is designed for an operational endurance of 12 hours and an emergency endurance of up to 96 hours. It features state-of-the-art systems such as a high-density Li-Po battery, underwater acoustic telephone, drop-weight emergency escape mechanisms, and bio-vests for crew safety and health monitoring.
The hybrid technique called Laser-Assisted Turning (LAT), that combines localized laser heating with mechanical cutting of such superalloys using tools coated with materials like tungsten carbide and CrAlSiN nanocomposite as well as the wear mechanisms of tungsten carbide cutting tools during the machining of IN625 superalloy, paves way for next-generation turbine blades, surgical tools, and high-performance automotive parts that are lighter, stronger, and more efficient.
Alzheimer’s disease (AD) is a debilitating condition affecting numerous people worldwide, with its prevalence expected to increase significantly in the future. It accounts for 70-80% of dementia cases and is the 5th leading cause of death, posing a substantial socioeconomic burden on the healthcare sector and society. The disease is characterized by the accumulation of protein clumps in the brain, memory loss, and cognitive deficits.
The study, spearheaded by Prof. Ashis K. Mukherjee, Director of IASST, and Ms. Susmita Nath, research scholar, among others, found that the secret behind the danger of the sting lies in 25 distinct toxins spanning eight different protein families packed in the venom that the scorpion injects.
A team of scientists from Institute of Liver and Biliary Sciences (ILBS) New Delhi, and National Institute of Pharmaceutical Education and Research (NIPER) Guwahati, ventured to probe the therapeutic efficacy of VEGF-C in ameliorating gut lymphatic dysfunction and improving lymph drainage. They studied if VEGF-C could help reduce ascites and attenuate inflammation in end-stage liver cirrhosis.
Metals in the cloud is a matter of growing concern due to its adverse impact on human health on a wider scale through continental long-range transport. However, information regarding metal contamination of low-level clouds, particularly the late summer and early monsoon clouds in India is lacking,
