In a major leap toward self-reliance in defense technology, India is set to develop its very own fifth-generation fighter jet—the Advanced Medium Combat Aircraft (AMCA) . In a historic move, Defence Minister Rajnath Singh has approved an innovative execution model for the indigenous stealth fighter programme. This model brings together Hindustan Aeronautics Limited (HAL) and private industry players in a competitive framework, marking a significant shift in how India approaches military aviation manufacturing. This bold initiative comes at a critical time, as China has already fielded two fifth-generation fighters , and reports indicate it will supply 40 J-35 stealth jets to Pakistan . Against this backdrop, fast-tracking the AMCA has become an urgent national security imperative. AMCA: India’s Indigenous Stealth Fighter Dream The AMCA project , spearheaded by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO) , received its l...
The Future is Fluid: Scientists Create Shape-Shifting Robots That Flow Like Liquid & Harden Like Steel
The Future is Fluid: Scientists Create Shape-Shifting Robots That Flow Like Liquid & Harden Like Steel Introduction In a groundbreaking advancement in robotics and materials science, researchers have developed shape-shifting robots that can transition between liquid and solid states. Inspired by nature, particularly the properties of sea cucumbers and the fictional T-1000 robot from Terminator 2 , these robots offer a new frontier in adaptive, self-healing, and flexible machines . This innovation could transform fields ranging from medicine to space exploration. Key Features of Shape-Shifting Robots Liquid-Solid Phase Transition These robots can liquefy , flow through tight spaces, and then harden into a rigid structure. The transition is controlled via magnetic fields and temperature variations . Magnetically Responsive Material The robots are made from a unique composite material: gallium (a metal that melts at low temperatures) mixed with magnetic particles . This enables ext...
