The kidneys filter the blood. They remove wastes, regulate the blood pressure, fluids, electrolytes, synthesis of red blood cells and vitamin D levels among other functions. Renal failure damages the ability of the body to regulate these...
Fluorescent lights are coated internally with powdered minerals. They glow in many brilliant colors when their atoms are excited by ultraviolet, or UV, light. When you switch on the power, neon or argon gas, or a small amount of mercury or sodium...
Kidneys maintain a balance of calcium in the body. During renal (kidney) failure, this mechanism no longer works effectively. Too much calcium in the blood causes hypercalcemia, which leads to a cascade of negative reactions on chemicals and...

Himalayan salt is said to contain 84 minerals that are good for your health. However, not all of the ingredients in Himalayan salt are technically minerals; some, such as hydrogen and oxygen, are elements but not minerals. Spectral analyses done...
A "carbon footprint" refers to the amount of carbon dioxide (CO2), and sometimes other "greenhouse gases" like methane, produced by a person, activity or product. The calculations of a carbon footprint are simple in principle, but can become...
While the concept of a partially or fully electric vehicle is more than 100 years old, practical hybrid vehicles have only emerged into the mass market over the past 10 years. A hybrid vehicle can be based around one of several distinct powertrain...
