  Did you know Scientist can now grow Mini Brains in the lab? Let’s explore the theory and motive behind growing mini brains in the lab WHAT ARE MINI BRAINS? Mini Brains also known as organoids are tiny versions of human brain that are grown in the lab. They aren’t real conscious brains that can think or remember things like we do. But they are made from original human cells and are capable of mimicking the developments and functioning of parts of the brain. They are about the size of a pea and are used as models to understand the brain better. How are Mini Brains made? Mini- brains are grown from stem cells- these are special cells that can differentiate into any other type of cell in the body. -Scientist extract stem cells from a human (either from an embryo or adult cells) -These cells are then treated with special nutrients and are signaled to grow into brain cells. -For its better growth and development, these cells are placed in a 3D gel- like material to ...

  How Your Body Repairs Itself: The Fascinating World of Regeneration! Have you ever wondered how your skin heals after a cut? Or how your liver repaires back after damage? The secret lies in your body's ability called regeneration — a process that works silently to repair and renew. Let’s explore this process step by step and understand the biological magic happening inside you. What Is Regeneration? Regeneration is the process through which organisms repair or replace damaged or lost tissues, organs, or cells. It’s a critical part of healing and maintaining the body’s normal functions. Types of Regeneration: 1. Complete Regeneration In complete regeneration, the lost or damaged part is replaced by tissue identical to the original .  In animals: Salamanders can regrow limbs with bones, muscles, and even nerves. In humans: Liver regeneration is almost complete — it regrows the same functional tissue. 2. Incomplete Regeneration Here, the...

Why Do We Remember Some Things Forever But Forgets The Remaining— Science Behind Memory.   Biology textbooks are filled with facts, yet there's one sentence almost everyone remembers long after school: “Mitochondria is the powerhouse of the cell.” Why this line? Why not something else—like the function of ribosomes or the phases of mitosis? To understand why certain facts stay in our minds while others fade away, we need to explore the science of memory —how the brain learns, stores, and recalls information. 1. How Memory Works: The Three Key Stages Memory is not just about storing information; it involves three major stages: Encoding : This is when the brain takes in information through attention and understanding. Storage : If the brain deems the information important, it is stored in short-term or long-term memory. Retrieval : This is the process of recalling stored information when needed. These steps involve various parts of the brain, including: The hip...
