Energy leaders and policymakers have called for creating a diversified portfolio of future-ready power system technologies, including advanced transmission networks, flexible generation resources, and modern distribution systems to ensure reliability, resilience, and security of supply, with India steadily moving to achieve a target of 500 GW non-fossil capacity. At the conclusion of the Global Energy...

Cosmic or galaxy filaments are the largest ‘threads’ in the universe’s cosmic web. A single cosmic filament is a structure spanning hundreds of millions of lightyears, formed as a result of gravity pulling in gas, dark matter, and galaxies into long, thin strands that link giant clusters of galaxies. Filaments also surround large, empty regions...

Why is the leaky faucet – that most irksome domestic malaise – so universal? A new scientific breakthrough seems to have cracked the physics of this incessant drip-drip. A new paper published in Physical Review Lettershas explained how a water jet breaks up into unstoppable droplets. Researchers from the University of Amsterdam found that the...

Nuclear activities worldwide generate around 200,000 m3 of radioactive waste every year. Of this about 10,000 m3, less than 5% by volume but containing most of the radioactivity, needs deep, long-term geological storage in the form of geological disposal facilities (GDFs). These caverns purpose-built hundreds of metres underground are packed with waste containers, cement backfill,...

Helical paths are everywhere in the microscopic realm. Many bacteria and parasites don’t simply swim or glide in straight lines. In three dimensions, they trace corkscrew-like tracks through their surroundings. Malaria parasites, for example, glide through soft 3D gels and, in the skin of a bitten host, on paths that look like stretched springs. For...
