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...

  When most people hear the word “microwave,” they think of the kitchen appliance that heats up leftovers. But in the world of engineering, microwave refers to something far more advanced and essential — a field that shapes how we connect, communicate, and share information at high speeds. Microwave engineering deals with the study and design of devices that operate in the microwave frequency range — usually between 300 MHz and 300 GHz. These waves play a key role in everything from satellite links and radar systems to 5G networks and remote sensing technology. As the world leans further into digital infrastructure, this once-niche area of electronics is gaining wider attention. Where Microwave Engineering Is Making Waves The push for faster internet, clearer communication, and smarter devices has turned microwave engineering into one of the unsung heroes of modern innovation. 5G and Beyond: The rollout of 5G networks depends heavily on millimeter-wave technology, w...

Talk of climate change often revolves around rising seas, melting glaciers, or soaring temperatures. But beneath the surface, quite literally, another transformation is taking place—one that poses a growing concern for engineers and builders across the globe. Soil, once considered relatively predictable, is starting to behave in ways we haven’t seen before. If you’ve been in construction or engineering long enough, you know that the stability of any structure depends on what liesbeneath it. But with changing rainfall patterns, longer dry spells, andshifting groundwater levels, even that foundation is now becoming less certain. Let’s dig into why. Dry One Day,Soaked the Next Soils don’t like extremes. When they get too dry,they shrink; when they take on too much water, they swell. Now imagine this happening again and again, every season. That’s what engineers are dealing with, especially in areas with clay-rich soils. These are the types that expand and contract like sponges depen...

It has been over four decades since India sent a citizen to space. In 1984, Rakesh Sharma etched his name into history. Now, in 2025, Group Captain Shubhanshu Shukla has reignited that sense of national awe by becoming the first Indian in 41 years to embark on a human spaceflight. But beyond the scientific marvels and aerospace headlines, his journey aboard the Axiom-4 mission tells a deeper story — one of emotion, identity, and cultural diplomacy. While the mission itself carried payloads for scientific study, it was the symbolic weight of the mission that captured public imagination — a white swan named Joy , a handcrafted statue of Ganesha, and a message that space exploration is as much about who we are as it is about where we go. Not Just a Mission — A Message Shubhanshu Shukla didn’t just represent Indian science or defense excellence; he embodied the hopes of a billion people. The astronaut, who goes by the nickname “Shux,” took flight aboard SpaceX’s Crew Dragon cap...
