      How Do Neurons Work?

      The neuron is the cell responsible for the transfer of information and electrical impulses around the body. Neurons work by transferring electrical charges from neuron to neuron to get from one point to another. All data, therefore, is transferred in this electrical fashion which is why computer science has become such an important tool in

    • MRI Video Goggles

      MRI Video Goggles

      MRI video goggles were designed to assist Magnetic Resonance Imaging (MRI) patients from experiencing the effects of claustrophobia by providing 3d video and audio. The goggles immerse the patient DVD video and audio assisting them in avoiding the uncomfortable feeling and mental anxiety of being in a very small contained area for a period of

    • What is Electrotherapy?

      What is Electrotherapy?

      Electrotherapy is a medical technique in which an electric current is used to perform a wide variety of tasks associated with pain, neurological disorders, muscle-related conditions, and drug delivery. Electrotherapy includes a range of medical techniques, some of which are under much debate and criticism. While electrotherapy itself is an accepted form of medical treatment,

    • How Laser Hair Removal Works

      How Laser Hair Removal Works

      Laser hair removal, as its name suggests, is using a laser to remove any hair that is unwanted. The majority of the process is done with a thin light beam of laser passing through the area of the skin that is being treated. Within the skin, specifically the dark pigment, also known as the melanin

    • Methyl Iodide

      Methyl Iodide

      Methyl Iodide is a chemical compound that is relatively volatile. It is commonly found in the form of a dense, colorless liquid. It is also known as iodomethane and has the chemical formula CH3I (one carbon atom with three hydrogen atoms and a single iodine atom connected to it). Methyl iodide is a naturally occurring

    • Harmonic Scalpel

      Harmonic Scalpel

      Electrosurgery is the the term used when high-frequency electrical current is used to cut, fulgurate, desiccate, or coagulate tissue with very little blood loss during surgery. The Harmonic scalpel is one of two competing brands in this field that help increase a surgeon’s efficiency and reduce the overall recovery time for patients. The device consists

    • How Do Neurons Communicate?

      How Do Neurons Communicate?

      Neurons communicate by sending electrical signals throughout the body. The exact process is an electrochemical one and the speed in which neurons communicate is so fast that seeing someone drop out of someone's hand and trying to grab for it–a process that requires the image to get into the brain, processed and then a signal

    • What Causes Left Handedness?

      What Causes Left Handedness?

      Left handedness is a person's preference in using the left hand over the right hand which, when considering the number of people, is relatively rare. It is believed that anywhere from seven to ten percent of the adult population is left handed. The rest are predominately right handed. The fundamental problem when discussing left handedness

    • 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.

    • DNA Fingerprinting

      DNA Fingerprinting

      DNA fingerprinting is the process of taking a cell sample from a person and analyzing it. This technique involves analyses of less than 0.1% of human DNA (which is different for each person). Though small, this 0.1% of DNA is enough to distinguish one individual from another and can be used to determine maternity/ paternity
