DRDO Secures Patent for Indigenous BAM-H24 High-Energy Fuel for Advanced Solid Rocket Propulsion

BAM-H24 is rich in boron, hydrogen and nitrogen, elements of considerable interest in high-energy propulsion chemistry. According to the University of Hyderabad, the compound combines strong chemical and thermal stability with relatively low sensitivity to impact and friction. It is also non-hygroscopic, helping it resist moisture absorption during storage and handling.

Indrajaal Expands Made-in-India AI-Powered Anti-Drone Defence for Critical Infrastructure

At the centre of the architecture is SkyOS, Indrajaal’s AI-driven autonomy and air-command platform. SkyOS combines information from acoustic sensors, radio-frequency systems, electro-optical cameras and thermal sensors to create a common picture of low-altitude airspace. The platform can classify an incoming drone, predict its trajectory and select an appropriate response within seconds.

TriNano Technologies: India’s Nano-Coating Push to Make Solar Panels Cleaner, Cooler and More Productive

Mumbai-based TriNano Technologies Pvt. Ltd. is attempting to solve this problem at the surface of the solar module itself. The SINE IIT Bombay-incubated deep-tech company has developed an indigenous solid-state nano-coating designed to combine self-cleaning, anti-reflection and light-trapping properties in a layer only a fraction of the thickness of a human hair.

Kachchha in the Mahabharata: The Ancient Kaccha Region of Gujarat’s Kutch

Yet Kachchha occupies a different place in the Mahabharata from kingdoms such as Chedi, Matsya or Saurashtra. The epic clearly names the Kacchas as a people or regional community, but it does not provide a securely identifiable Kachchha king, capital or royal dynasty connected with the central narrative. It is therefore more accurate to understand Kachchha as an ancient geographical and cultural region mentioned in the Mahabharata, rather than constructing a detailed royal history that the text itself does not supply.

Yudhishthira and the Faithful Dog: The Final Test of Dharma on the Road to Heaven

When Indra arrives in a celestial chariot and offers Yudhishthira entry into heaven, the king faces his final test. Indra refuses to allow the dog to accompany him, but Yudhishthira declares that he will not abandon a creature that has remained loyal to him. At that moment, the dog reveals itself as Dharma, Yudhishthira’s divine father, who had taken animal form to test his compassion, loyalty and commitment to righteousness.
