  What Is Alzheimer’s – and Why Should We Care Early? Alzheimer’s disease isn’t just about forgetting names. It’s a progressive brain disorder that deeply affects memory, personality, thinking, and daily functioning . Many believe it's only a "senior citizen problem," but here's the truth: Alzheimer’s starts silently in the brain 10 to 20 years before any symptoms appear. In this blog, we’ll break down the complex science of Alzheimer’s in simple words , explore what causes it, what it does to your brain, why early care matters, and how lifestyle plays a major role.   What Exactly Is Alzheimer’s? Alzheimer’s is the most common form of dementia , which is a general term for loss of memory and thinking skills. In Alzheimer’s: Brain cells slowly die , and Brain tissue shrinks , especially in areas that control memory and learning. DYK? (Did You Know?) Alzheimer’s affects over 55 million people globally. It's now called Type ...

  Why Are Heart Attacks Happening to Fit People? He looked healthy. He exercised daily. He never smokes or drinks. And yet — he suffered a heart attack. This is happening more often. Many young, active, and seemingly healthy people are falling victim to sudden heart attacks. The truth? Looking fit from the outside doesn’t guarantee your heart is healthy on the inside. In this blog, we’ll explain why even fit people are at risk, and how each factor directly affects the heart. What Exactly is a Heart Attack? A heart attack happens when blood flow to the heart is blocked , usually by a clot. This blockage is caused by plaque buildup in the arteries — made of cholesterol, fat, and other substances. When the heart doesn’t get oxygen-rich blood, heart muscle begins to die — and this can be fatal. Causes of heart attack 1. Hidden Inflammation & Genetic Risks Many people are born with certain genes that make them more likely to develop heart disease — even if th...

  Artificial Blood: Are We Close to Lab-Made Life Savers? Every two seconds, someone in the world requires a blood transfusion. But what do we do when there's a shortage of blood? What occurs if we can’t find a donor promptly? This is where the idea of artificial blood comes into play. The notion of generating blood in a lab—safe, sterile, and always accessible? ARTIFICIAL BLOOD : A prospective answer for disaster response, surgical procedures, and urgent medical scenarios. Let’s dive into the true essence of artificial blood, how it functions, the science behind it, and the possibility of it becoming available in hospitals soon. What is Artificial Blood? Artificial blood are not entirely like the blood (which includes red cells, white cells, platelets, and plasma). Rather, it concentrates on oxygen-transporting role of red blood cells (RBCs) — the crucial component in emergency situations.   There are two primary categories of artificial blood alternatives: 1 ...

  Biotech Bananas That Don’t Rot: Can Science Really Stop Food Waste ? Have you ever bought bananas that turned brown just two days later? Or watched them go mushy before you could eat them all? Bananas are one of the most wasted fruits around the globe, and therefore scientists are now using biotechnology to solve this problem. Let’s learn how biotech bananas are being developed to stay fresh for longer duration and how it helps farmers and the planet. Firstly, why Do Bananas Rot So Quickly? Before we talk about how science is solving the problem, let’s first understand how bananas spoil fast: 1. Natural Ripening Gas – Ethylene Bananas are capable of releasing a gas called ethylene that helps I its ripening however once it starts, the process speeds up very quickly. It’s more like a chain reaction where one ripe banana can cause others nearby to ripen faster. 2. Soft Skin and Bruising Bananas have thin, soft skin which makes it prone to bruises during transp...

  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 ...
