 Many of us keep cracking our knuckles when we are worried/ stressed/ anxious/etc., so I have always wondered why this cracking happens. So I just took a bit of time to sit down and pen down my possible thoughts of why this knuckle cracking takes place, and the following is the context behind it, according to me, after coming across a few studies. There aren't any awards to be won for solving the most minor science mysteries - like why yawning and laughing are contagious - but that doesn't mean we don't want the answers anyway. Add to those everyday puzzles the mystery of knuckle cracking. Why exactly does this cracker burst occur from some of the body's smallest joints? The type of joints that you can most easily 'crack' or 'pop' are the diarthrodial joints. These are the most typical joints. They consist of two bones that are in contact with each other at their cartilage surfaces; the cartilage surfaces are surrounded by a joint capsule.  Inside the jo

  Heyy ! I have had my exams all this while so couldn't post anything earlier. But I'm back again with yet another post to make the scientific track going! The human body handles glucose and fructose - the most abundant sugars in our diet. Every cell of our body can break down glucose for energy. However, in contrast, the only ones that can handle fructose are our liver cells. What the liver does with fructose, especially when too much fructose intake takes place, has potentially dangerous consequences for the heart and the liver. Fructose, also called fruit sugar, was once a minor part of our diet. Today, it turns out to be a major part as almost all of the major part comes from the refined sugars (sucrose - half glucose, half fructose) used to make beverages, fruit drinks, sodas, pastries and other sweet foods, and breakfast cereals.  High sugar intake has been linked to several health complications, including - cancer, obesity, type 2 diabetes, and cardiovascular diseases.
