So, he would be thrilled whenever he had a chance to visit his father’s metal fabrication shop, where he witnessed how sheets and rods of steel were shaped into garage doors, gates and […]
India is betting big on lithium-ion batteries, but at what cost? In 1817, Johan August Arfwedson, a Swedish lawyer and mineralogist, was studying the mineral petalite in the laboratory of the renowned chemist Jacob Berzelius.

The reality is that although robots have evolved significantly in the last few decades, […]
Cryo-EM, an emerging technique, is allowing scientists to better zoom in on cells and molecules “Like any living organisms, we are a bag of water, formed from billions of cells which all are small bags of water. Since air is not transparent to electrons, an electron microscope must operate under vacuum – which […]
After centuries of sky-watching, we are yet to understand the complex nature of clouds It’s an early winter dawn. The lake seems to be steaming, but it is not. A cloud is being born. I am on a hilltop, watching a village in the valley sparkling in the early morning rays when a white sheet […]
Cells can apply and sense forces to communicate and coordinate with each other. Scientists and engineers have teamed up under the mechanobiology banner to study these cellular forces The outermost and the innermost surfaces of any organ are lined by the ‘epithelium’, a tissue composed of cells arranged in a sheet. For instance, the […]
The tiny molecule that wears many hats inside our body A memory brings a smile as I gulp down water to quench my thirst. School, science class, and tiny desks. Our teacher was explaining to us that “water is colourless, odourless, and tasteless.” “But miss, I can taste water!” one of my classmates piped […]
The soil under our feet is teeming with life, and understanding and nurturing it has a positive impact on our lives A memory. My friend and I followed the ball as it bounced towards the pit in the backyard. Heat wafted up, and the air was saturated with a warm, earthy smell that wasn’t […]
