Scientists used mathematical models and satellite data to understand how seed dispersal from forest trees helps in maintaining the savanna–forest boundaries.
Researchers at the Indian Institute of Science have developed a new technique that can effectively print a wide range of liquids inks including biopolymers, biological solutions containing cells, as well as water-based inks.
Scientists study evolution of liquids on spherical surfaces and their properties.
In a new study, researchers devise a unique way to observe the process of devitrification under a microscope, in real-time.
In a recent study, researchers at the Indian Institute of Science (IISc), Bengaluru, and Christian Medical College, Vellore, have developed a novel, inexpensive and easy-to-use device to detect tuberculosis.
In a series of studies, researchers have investigated how the Hemidactylus geckos, or leaf-toed geckos, evolved during the two periods of climate change.
A ventilator can be a life-saver for patients whose lungs are damaged by the COVID-19 infection. But India, like all countries grappling with this pandemic, is likely to face a large shortage of ventilators. Manufacturers are unable to source key components such as sensors and flow controllers from abroad due to the current disruptions in global supply chains.To address this shortage, a team of engineers at the Indian Institute of Science (IISc) is currently building a prototype of an electro-mechanical ventilator from scratch, using only components found or made in India, based on guidelines issued by the UK Medicines and Healthcare Products Regulatory Agency. It is expected to be ready within the next couple of weeks.
Nature is an enigma; an ensemble of complex structures and functions come together to form a variety of mesmerising artefacts, including life. Richard Feynman, the well-known American Nobel Laureate and physicist, famously said—"Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy".
Understanding patterns in nature has been of interest to researchers. Some of the popular questions have been around why birds flock together, how groups of bees build their honeycombs out of perfect hexagons, how ants navigate finding the shortest path back to the nest, and the likes. Researchers across the world are trying to decipher and explain how and why such specific patterns emerge.
Researchers from the Indian Institute of Science, Bangalore; Indian Institute of Tropical Meteorology, Pune; and Florida State University, USA; have mathematically computed a multidecadal variability in the Indian summer monsoon rainfall and the global sea surface temperature. They have established that Indian monsoon rainfall exhibits a 67-year oscillation and is closely linked to the sea surface temperature cycle, which also shows a similar 67-year swing. The study also shows that 80% of all droughts have occurred in the rainfall cycle’s ‘negative phase’, associated with a below-average rainfall; whereas 60% of all floods have occurred in the positive phase, marked with above-average precipitation. Their findings have been published in the Quarterly Journal of the Royal Meteorological Society.
