  Why Are Some People Left-Handed? The Genetics Behind Handedness Have you ever noticed how most people naturally use their right hand for tasks like writing, throwing, or eating? Yet, about 10% of the world’s population is left-handed . Why is that? Is it just random, or is there a deeper reason behind it? The answer lies in a fascinating mix of genetics, brain function, and even evolution . Let’s dive into the science behind left-handedness and uncover what makes left-handers unique! The Mystery of Left-Handedness: A Genetic Puzzle One of the most intriguing questions about left-handedness is: Is it inherited? The short answer is yes—but not in the way you might think . Unlike eye color, handedness doesn’t follow a simple inheritance pattern. Scientists have been hunting for the so-called "left-handed gene" for years. While they haven’t found just one, they have discovered multiple genetic markers, such as the PCSK6 gene, which helps shape brain asymmetry. However, ...

 Blood is the lifeline of the human body. It carries oxygen, nutrients, and immune cells, keeping us alive and healthy. But did you know that not all blood is the same? Blood comes in different types, and while some are common, others are so rare that only a handful of people in the world have them. Among these is the extraordinary Golden Blood , or Rh-null blood —a type so rare that fewer than 50 people worldwide have been identified with it. In this blog, we will explore what makes Golden Blood so unique, why it is both a blessing and a challenge, and why blood donation, no matter your type, is one of the most selfless acts you can do to help save lives. Understanding Blood and Its Classification To understand Golden Blood, we first need to look at how blood is classified. Blood types are determined by the presence or absence of specific proteins, called antigens, on the surface of red blood cells. These proteins help our immune system recognize our own blood and differentiate it...
