Nanomachines (nanites) are small computers that are measured in nanometers and can perform tasks on a molecular level. They are relatively new, and while only a theory just a few years ago, they are quickly being integrated into a wide variety of industries and products. It has been projected that within one or two decades, nanomachines will make it possible to do many new things such as decipher the human genome, change the flavor of any food on demand, and create body armor that is both stronger and lighter than Read More

An ionic air purifier is a device that uses an air ionizer to filter dust, smoke, and other harmful particles from the air. An ion is an electrically charged molecule that can either have a negative or positive charge. Positively charged ions have one or more less electrons, while negatively charged ions have one or more extra electrons. Ionic air purifiers almost always produce negatively charged ions, allowing them to attract positively charged molecules. How does an Ionic Air Purifier Work? An ionic air purifier consists of a metal plate Read More

As recent events concerning oil spills in multiple locations have flooded the news, many people are wondering how oil drilling works and why something like an oil spill can happen. This article will attempt to answer these questions by explaining how the various processes of oil drilling work. What is an Oil Rig An oil rig, or oil platform, is a large processing center that is able to extract oil from the Earth, refine it, and distribute it throughout the world. Oil rigs are often dangerous places to be as Read More

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 view of the body which medical examiners, coroners and pathologists can use to examine the state of the blood vessels, organs, bones and tissues of a body and thus determine the cause of death and Read More

Radiation sickness, or radiation poisoning, is damage caused to organ tissue due to heavy exposure to ionizing radiation. In most cases radiation sickness is caused when you are exposed to a large dosage of radiation in a short period of time. Exposure It is unlikely that you will be exposed to large doses of radiation unless you are intentionally poisoned, which is uncommon, or if you work in a factory setting that either produces or utilizes a large quantity of radioactive material. There is a possibility of getting radiation sickness Read More

An ultrasonic nebulizer is a small, portable device that uses ultrasonic sound waves to break liquid particles down into a fog so that they can be inhaled easily. Patients who have asthma, COPD, pneumonia, chronic bronchitis, emphysema, or other chronic conditions, most often use them for medicinal purposes. While other devices can deliver the medicine in a mist form, ultrasonic nebulizers provide a fog of medicine that has much smaller particles and can travel much deeper into the patient’s lungs, resulting in much faster relief. How does an Ultrasonic Nebulizer Read More

Robotics technology is now being utilized in the field of medicine because it offers the high precision and control that minimally invasive procedures require. Robotics are now being used in gallbladder surgery, heartburn and gastroesophageal reflux correction and endoscope positioning. In the future, the applications of this technology will encompass closed-chest beating-heart surgery. Advantages of Robotic Surgery Less Personnel Required Because the surgical robots could take over the job of some of the people inside the operating room, future surgeries will require fewer personnel yet still be able to perform Read More

Holograms are three-dimensional images produced through photographic projection. Unlike 3-D graphics or Virtual Reality or Augmented reality displays where the image is projected in a two-dimensional surface and where the illusion of depth is applied, holograms are truly three-dimensional images that do not need special viewing equipments. The first hologram was created in 1947 by Dennis Gabor while doing research on improving the resolution of electron microscopes. The lasers needed for displaying and creating these holograms, however, did not exist until 1960. Categories of Holograms Holograms can be categorized into Read More

For the past two decades, lasers have been used to measure distance without having to physically touch the area or things being measured. Laser measurement is capable of very precise and quick distance measurements. Lasers have been used in military targeting, criminal investigations, and sports. As research has progressed, the size of laser measuring devices has decreased, while computer power capable of interpreting and using measurement data has increased. What Techniques Do Lasers Use to Measure Distance? A laser uses several techniques to measure distance. They include: Time of Flight Read More

The first instrument used to measure the strength, direction, and presence of an electric current in a conductor was a galvanometer. Their design is based on the premise that a magnetic needle moves in the presence of electric current in a conductor placed near the galvanometer. When the current flows through the conductor, the needle turns parallel to the line of induction about the conductor. The north pole points in the induction flow’s direction and how much the needle turns is based on the electrical current’s overall strength. Who Invented Read More
