The Uncontrollable Growth of Cancer Various risks factors can contribute to the development of cancer, but the cause of this rampant disease is uncontrolled cell growth. Cancerous cells divide without limit because of the production of the enzyme telomerase that speeds up the process of cell division. Cancer cells derive from mutation in genetic DNA, and becomes carcinogenic cells that renew themselves indefinitely. When this fatal continuous process occurs, it results in a tumor. Although…

Both IR and UV spectroscopy are methods of measuring the wavelengths absorbed by a tested material. IR spectroscopy measures the absorbance of the tested material in the infrared spectrum, the section of the electromagnetic spectrum with a lower frequency than that observed in the visible light spectrum. Conversely, UV spectroscopy measures the absorbance of the tested material in the ultraviolet spectrum, the section of the electromagnetic spectrum with a higher frequency than that observed in…

Do you think you could live in a world without your phone or computer? What about a world without electrical power at all? Well if an Electromagnetic Pulse, also known as an EMP were to occur, it would change the technology world forever. Such threats are often dismissed as unlikely or a relic from the Cold War. They are not. Solar storms are not infrequent, making it only a matter of time until one impacts our critical infrastructure. And unlike natural phenomena, there is no reliable…

rays and charged particles are used to damage the DNA of cancer cells in an attempt to destroy the tumor and stop the cancer cells from growing out of control. Radiation can damage the DNA directly or indirectly as its application creates free radicals within the cells. Interactions involving cell killing in the realm of photon radiation therapy are mostly due to indirect damage. Free radicals are molecules with unpaired electrons, leading them to be unstable and react quickly with other…

1. Doppler radar systems provide information about the movement and position of targets. They work by sending a beam of electromagnetic waves at a specific frequency, at a moving object. When a microwave bounces off the object, its wavelength shifts as the object moves (this is known as the Doppler effect). The radar detects the shift and calculates how fast the object is traveling, along with it's location. 2. Polarized sunglasses block reflected light (glare). Since polarized light waves…

The stages of melanoma Staging is a way to define where cancer located, where it spread and improve, also it affect other parts of the body. Doctors use diagnostic tests to know which cancer's stage, so determined the stage may not be complete until all of the tests are finished. Knowing the stage help doctor to decide what kind of cure is best and can assist to forecast patient's prognosis, which is the chance of recovery [1]. There are five stages of melanoma cancer. The First…

Is Medicine for you? “Wherever the art of Medicine is loved, there is also a love of Humanity.”― Hippocrates Nuclear medicine technologist are really passionate about what they do, their job is to find a treatment or the diagnoses the patient has and their one mission is to help the patient be healthy as possible. Most people are not familiar with nuclear medicine which is common because it is not popular in the medical field but if interested in the medical field but not into the whole bloody…

Radioactive decay occurs when the nucleus discharges an abundance of energy, in the type of waves, causing nuclear instability which can occur naturally or spontaneously. Alpha (α), beta (β), and gamma particles (γ) are the most known types of radioactive decay despite the fact that there are some more. Alpha decay, α, composes of two neutrons and two protons making alpha particles similar the nucleus of helium. Large components, for example, uranium, radium, and thorium have a greater number of…

Society as we know it today has become dependent on the use of synthetic materials, natural materials that have gone through a chemical change to become man-made, therefore, synthetic. Some synthetic materials are easier to create than others, these materials range from plastic, to nylon, to cocaine, to medicine, and much more. Synthetic materials play a large role in our lives and they surround us everyday, although, it hasn't always been this way. Earth and humans aren't always accustomed to…

Skin cancer is on the rise. Fortunately, there are many treatments available. Proper diagnosis and early treatment are the keys to surviving skin cancer. A mole is often the first sign of skin cancer. However, it is important to note that every mole is not cancerous. It is recommended that you see a dermatologist if you suspect that a mole is cancerous. Below are some tips that can help people determine whether a mole is cancerous: Asymmetrical One of the things that you will need to pay…
