What do chiropractors do?
|
view preview
Chiropractic medicine is an approach that is derived from the Greek roots " cheir," meaning hand, and " praxis," meaning practice, and was formulated by the founder of chiropractic, Daniel David Palmer (originally of Canada), to mean " done by hand." The emphasis in chiropractic is on the use of physical manipulation or adjustments to correct misalignment of the spinal vertebrae and other musculoskeletal joints to improve the function of the related organs and musculature. The main treatments used by chiropractic physicians are adjustments, or physical manipulation of the musculoskeletal system. Chiropractors also use heat and/or cold therapy, immobilization (with splints, for example), hydrotherapy, ultrasound, and massage. Chiropractic treatme ...

Child with ADHD vs. one who is simply more active
|
view preview
What's the difference between a child with attention-deficit hyperactivity disorder (ADHD) and one who is simply more active than other children?Many children are rambunctious, to an extent that their parents or teachers find somewhat worrisome. Figuring out how to distinguish between normal high-energy levels and pathological overactivity can be quite difficult. Furthermore, the distinction can be complicated by parental tendencies to be permissive and to fail to set up clear rules, reprimands, or restrictions for when a child steps outside the limits. Figuring out how to make this distinction is not a trivial issue. Children diagnosed with ADHD are usually prescribed methylphenidate (Ritalin) or other medications that lessen their activity ...

Four color theorem
|
view preview
The Four Color Theorem is a famous mathematical theorem that states that no more than four colors are required to color the regions of any map so that no two adjacent regions have the same color. Adjacent means that two regions share a common boundary curve segment, not merely a corner where three or more regions meet. Unlike other proofs before its discovery, computers were used to resolve this long-standing mathematical conjecture that was first proposed in 1850 by Francis Guthrie. After more than a century later, mathematicians, Kenneth Appel and Wolfgang Haken, finally derived its proof in 1976, and determined that it is practicality impossible for humans to verify it without the use of a computer. According to the four color theorem, a ...

Wholphin: a fertile hybrid
|
view preview
A wholphin is a rare fertile hybrid born from mating a bottlenose dolphin ( Tursiops truncatus) (mother), and a false killer whale ( Pseudorca crassidens). Although they have been reported to exist in the wild, the first captive wholphin was born in 1945, where a bottlenose dolphin and a male false killer whale shared a pool. The wholphin's size, color and shape are intermediate between the parent species. For example, an adult wholphin has 66 teeth - intermediate between a bottlenose (88 teeth) and false killer whale (44 teeth). They are smaller than a false killer whale but are larger than a normal bottlenose. Normally, when two different, yet similar species mate, such as a female horse and a male donkey forming a mule, the progeny is expec ...

Strange disease that causes fibers to grow underneath the skin
|
view preview
Imagine a disease whose presence is marked by a feeling of something crawling along your skin, stinging every part of your body as if there is insect or parasite infestation that doesn't go away. Not only that, but your skin is plagued with the presence of multicolored filaments that lie under, are embedded in, or project from skin. Morgellons disease (pronounced with either a hard or soft "g") is a highly misunderstood skin condition that was first reported in the USA in 2002, although may have a longer history depending on where you look. The characteristic filaments described earlier are microscopic, visually resembling textile fibers, and are white, black, or a more vibrant color, such as red or blue (left image). In addition to fiber p ...

What is the purpose of stress?
|
view preview
The stress response exists for the purpose of survival. When we experience stress, our sympathetic nervous system activates, blood pressure and heart rate increase, and often we begin to sweat. These physiological reactions prepare us for "fight or flight." Our bodies are at optimal physical performance and alertness levels, and we are therefore optimized for survival in a physically challenging situation. Sometimes we use this physiological activation to our advantage: Consider a champion weightlifter who, prior to lifting an extremely heavy weight, "pumps himself up." By doing this, the weightlifter is attempting behaviorally to elicit a stress response from his brain and body in order to achieve the highest level of physical performance ...

The Science Behind Fasting and Bad Breath
|
view preview
Fasting is a practice that has been followed by various cultures and religions for centuries. It involves abstaining from food and, in some cases, beverages for a defined period. While fasting can have several physical and mental benefits, it is not uncommon for individuals to notice an unpleasant odor in their breath during fasting periods. Let's explore the reasons behind this phenomenon and uncover the science behind why one's breath may smell when they've fasted. When we fast or restrict our carbohydrate intake for an extended period, our body undergoes a metabolic state called ketosis. During ketosis, the body shifts its primary source of energy from glucose (derived from carbohydrates) to ketones, which are produced when the liver brea ...
