When we think about food, our attention usually goes to flavor, freshness, or maybe price. Yet, there’s an unsung hero that quietly protects what we eat: packaging. Once seen only as a wrapper or container, packaging is now evolving into something far more dynamic. Through advances in food engineering, we’re entering an era of smart packaging —innovations that extend freshness, improve safety, and cut down on unnecessary waste. Why Packaging Isn’t Just Packaging Anymore Decades ago, packaging simply kept food sealed and easy to transport. Today, expectations are different. Global supply chains, changing diets, and rising concerns over sustainability demand solutions that do more than contain. Every year, an enormous quantity of food is wasted before it even reaches a plate. Much of that loss happens because packaging fails to preserve it long enough or provide useful signals about its condition. Food engineers are tackling this problem head-on. They’re working on designs that can...

The idea of travelling halfway around the world in the time it takes to watch a movie has fascinated people for decades. For a long time, it sounded like something only science fiction could promise. Now, advances in hypersonic technology are bringing it within reach, creating a bridge between what we know from space travel and what could soon become everyday transport here on Earth. Understanding Hypersonic Speeds When engineers talk about “hypersonic,” they mean speeds starting from Mach 5—over 6,000 kilometres an hour. At that pace, a flight from Mumbai to London could be done in less than three hours. The appeal is obvious: quicker travel for people, lightning-fast cargo delivery, and entirely new possibilities for both business and leisure. But speed isn’t the only challenge. At these velocities, air friction heats a vehicle’s surface to extreme levels, control systems face intense pressure, and engines need to function in thin, fast-moving air. The solutions demand a combi...

There was a time when India’s space ambitions were seen as modest—important, yes, but not exactly headline-making. But things have changed. Today, ISRO isn’t just a technical agency; it's a source of national pride, scientific progress, and geopolitical relevance. And at the centre of this transformation lies something often overlooked: a clear and consistent push from the Indian government . This isn't just about sending rockets into the sky. It's about creating a framework—policy, investment, and education—that supports a long-term space ecosystem. And if the past few years are anything to go by, India is serious about claiming its place among the world’s most advanced spacefaring nations.   A Clear Shift in Priorities In the early days, ISRO’s focus was strictly utilitarian—remote sensing, weather updates, and basic communication services. Useful? Absolutely. But the scope was limited. It’s only in the last decade or so that space has become a core part of the g...
