The global fresh water supply has become a major concern as most third world nations, and even some developed countries, face the disconcerting reality that drinkable water is running out. To solve this newly realized crisis, engineers are offering the world new, innovative techniques for water purification. Nanotechnology, technological development

Biodiesel is a renewable source of energy that could potentially reduce the world’s dependence on coal and crude oil. It is a byproduct of refined vegetable and soybean oils, and it contains almost the same amount of energy per gallon as traditional diesel while having cleaner emissions when consumed. Biodiesel

The Botox injection is by far the most popular cosmetic procedure performed today. Botox, or Botulinum toxin A, works by blocking the release of a key chemical, acetylcholine, preventing the transmittal of signals from nerve cells to muscles. This unique effect makes it useful clinically in treating neurological and neuromuscular

The Walt Disney Concert Hall, designed by architect Frank Gehry, makes extensive use of computer technology. Without the use of CATIA (Computer-Aided Three-Dimensional Interactive Application), construction of the concert hall would have been impossible. After a physical model is built, the model is scanned by a laser device that transmits

Two retinal diseases, Age- Related Macular Degeneration (AMD) and Retinitis Pigmentosa (RP), are the leading causes of blindness in individuals over the age of 65. Despite various treatments such as gene therapy and retinal tissue transplant, physicians have thus far been unable to combat the blinding effects of these diseases.

At its essence, paintball is about marking other players with gelatin capsules filled with colored dye shot from a gun powered by compressed gas. While the fundamentals of the game have not changed since its inception, the technologies behind many of its principles have advanced. Fuelling this change is the

The skin is a complex organ with many layers. Its structure is designed to minimize moisture loss from the body while preventing foreign materials from entering. To accomplish these functions, the skin must have a protective covering of lipids, or oil-soluble molecules. Exposure to everyday conditions can strip the skin

The world of computing is a constantly evolving model of technological innovation, financial gain and ruin, and philosophical ideals. The open source revolution has placed these three branches of the industry in the spotlight, shaking the traditional foundations of the technology market. In a world of secrecy, and even deception,

The daily life of an average American is depending more and more on the Internet. Information and entertainment sites abound, but many of the billions of web pages are yet unknown. Search engines are the pipeline through which users can quickly find the content they desire. The history of online

In order to bring high-speed internet to areas where developing a traditional broadband infrastructure would be cost prohibitive, engineers have recently begun working on developing techniques for delivering broadband internet signals over the existing power supply grid. By using an entirely different frequency range, power lines can carry traditional AC

Mobile phones allow users to place calls, send text messages, and receive updates from the internet. Information from a mobile phone is sent and received by way of electromagnetic waves. All information is encoded prior to transmission, decoded upon arrival, and must be sent so that many users can share

Tele-Immersion (TI) involves the construction of a three dimensional (3D), realistic holographic environment where two or more physically separated users can communicate with each other in real-time. Existing video conferencing applications lack this dimensionality and realism. Tele-Immersion is an engineering solution to this deficiency and is made possible by combining

A collection of recently developed audio technologies allows for the creation of thin, directional sound beams. With this type of equipment, focused streams of sound can be pointed exactly where the user wants them. Directional sound technology will likely see widespread adoption in the near future as engineers continue developing

The launch of Sputnik in 1957 by the USSR marked the beginning of the satellite era. The next half-century saw new research and development that changed satellites into the useful tool of contemporary society. Modern satellites can help locate people all over the world, aid in scientific research, and perform

Radio Frequency Identification Devices (RFID) are widely being hailed as the up-and-coming successor to barcodes. The superiority of RFID lies in its faster speed, rewriting capabilities, and the fact that the device need not be visible to be read. However, until the cost of RFID is lowered, barcodes will remain

Beer has existed for thousands of years. During its long history its popularity has changed considerably in response to technological advancements and social pressures. Although beer was created before the science behind it was understood, the process of making beer can be thought of as a series of chemical engineering

The digital image sensor is a technology used to record electronic images. The most commonly recognized application of the digital image sensor is the digital camera. In digital cameras, the image sensor is used in conjunction with a color separation device and signal processing circuitry to record images. The two

Long before the age of computers, light bulbs, automobiles, or locomotives, a revolutionary feat in engineering transformed society. This technology almost singly separates developed countries from their developing counterparts, and many Americans take it for granted. Rarely do we ever think about it when we use it, and when we

The natural environment is very easily polluted by the toxic compounds contained in oil. In the past, methods for restoring contaminated areas have been expensive but largely inadequate. A recently developed decontamination process called phytoremediation uses plants along with the bacteria that live in their roots to break down the

Immersion is the process by which a media element entices a person to suspend their disbelief and accept what they are viewing on a screen or page as actual reality. Through non-linear dramatic elements and interaction between the player and the computer, a video game achieves a level of reality

The Frisbee, generally held to be a simple toy for children, was invented and refined in the late nineteenth century. Although it has grown in popularity since then, its general design, and thus the technique for its use, have remained fairly constant. The flight of a Frisbee is allowed and

Photochemical smog, created by any gasoline-powered vehicle on the road, is a major concern in Los Angeles today. Buses, despite being implemented to reduce this pollution by lessening the number of cars on the streets and freeways, are smoke-spewing machines that pose a risk to environmental and public health. They

The brain is our body’s information processing center. It controls everything that we do, making us intelligent, conscious, and alive. The brain is made up of over 100 billion neurons. The neuron, or nerve cell, is a type of cell responsible for the body’s gathering, processing, and transmission of information.
