    • What is Acesulfame Potassium?

      What is Acesulfame Potassium?

      Acesulfame potassium (Acesulfame K or Ace K, where “K” is the elemental symbol for potassium) is commonly used as an artificial sweetener or flavor enhancer. It is used in low calorie food products as it replaces sugar and other natural sweeteners that commonly add large amounts of calories. Acesulfame potassium’s trade names include “Sunett” and

    • How a Nuclear Bone Scan Works

      How a Nuclear Bone Scan Works

      In the last several decades, medical technology has advanced in leaps and bounds. One of the most advanced technological instruments used in medicine today is the nuclear bone scan. A nuclear bone scan uses a radioactive tracer and high-resolution camera to identify areas of new bone growth or areas in which bone has broken down.

    • What Are Nanorobots?

      What Are Nanorobots?

      A nanobot is an extremely small robot that operates on a microscopic scale. Originally spoken of in science fiction circles, there has been an increased focus on it in biological and robotics research. The term nanorobot was created by combining the terms robot and nanometer. Other common names for robots of this size include nanobots,

    • What is Bioluminescence?

      What is Bioluminescence?

      A living organism is bioluminescent when it produces and emits light. Most organisms that do this live in the sea. However, there are several land insects and plants that also have bioluminescent qualities, including the firefly. The trait has typically evolved in organisms that either need to communicate with each other or lure/detect prey. How

    • Electromotive Force

      Electromotive Force

      Electromotive force is the electrical potential energy that causes current to flow through a circuit. It results from the difference in charge between two points in a material. This difference is created when an external source such as a battery makes electrons move to both points so that there is an excess at the first

    • Virtual Autopsy

      Virtual Autopsy

      A Virtual Autopsy or Virtopsy is a new and non-intrusive form of performing an human autopsy. This system utilizes a Computer Tomography or CT unit and an (MRI) Magnetic Resonance Imaging unit to obtain a detailed view of a body. Here the MRI images and the detailed X-rays are combined to create a full three-dimensional

    • What Are Pennies Made Of?

      What Are Pennies Made Of?

      Before 1982, the penny was made of copper which is why they, unlike most other coins, don't look silver. However, after 1982, the U.S. government realized that it was too expensive to make a penny–more than the penny was worth in money–so they decided, instead, to make it with a mixture of two different metals.

    • What Are Ionic Compounds?

      What Are Ionic Compounds?

      An ionic compound is any compound in which an electrostatic force holds the ions together. Ionic compounds are made of positively charged particles that rest against negatively charged particles in order to balance out the two particles’ magnetic imbalance. They can be found in both solid and liquid states, although solid ionic compounds are poor

    • How Do Microwaves Work?

      How Do Microwaves Work?

      In the modern world, virtually everyone owns a microwave oven. How many people, though, stop to consider what exactly microwave ovens do or how they work? To anyone who has been alive over the past few decades, microwave ovens are as normal as anything else; to someone born even a century ago, however, they would

    • What Are the Five States of Matter?

      What Are the Five States of Matter?

      There are five states of matter that occur when physical forces are applied to them. These states are fairly easy to understand when their physical properties are observed. Depending on the type of matter that is being dealt with, the state of the matter may be more difficult to reach when applying these physical stressors. The best way
