World of Biology on Instagram: "Ever wondered "How Rotational Atherectomy is done?" It’s a minimally invasive procedure where doctors use a tiny diamond-tipped burr that spins at high speed to grind away hardened plaque inside blocked coronary arteries. This restores smooth blood flow, especially in cases where stents cannot pass due to heavy calcification. The burr is guided through a catheter, controlled precisely, and the debris is safely washed away by blood flow. A stent is often placed aft

Mr Moist on Instagram: "This is actually crazy Braces work by applying gentle, continuous pressure to teeth over long periods, triggering a biological process where the bone around each tooth slowly breaks down and rebuilds, allowing the tooth to move. Timelapse videos compress months or years of this movement into seconds, showing teeth rotating, shifting forward or backward, and gradually lining up as wires and brackets guide them into position. While the motion looks fast on screen, in realit

Wealth on Instagram: "For the first time in three decades, engineers lifted the gates of a massive dam, unleashing a controlled release of water that had been held back since the mid-1990s.🚨 😳 This was not a routine operation. Large dams are kept sealed for years to manage pressure, structural integrity, sediment buildup, and downstream safety. Opening one after this long requires precise engineering calculations to prevent erosion, flooding, or structural damage. As the gates rose, millions o
