The major causes of TBI include violence, falls, sports injuries and motor vehicle accidents. People can often prevent accidents when the proper safety precautions are taken. Traumatic brai
273: Radio Telescope Lets You Hear Into Space
To see beyond what astronomers can see using traditional telescopes, which count on visible light for their viewing, a radio telescope is designed to hear the sounds from outer space as opposed to the sights. Most designed as a parabolic antenna, a radio telescope allows the user to listen to sounds emanating from sources in space.
Most people w
274: Real MonstersFive Of The Scariest Creatures Of All Time
In the pleasantly safe and sterile modern world it is easy to assume that monsters only exist in the movies. We think that terrifying beasties are just the products of overactive Hollywood imaginations.
Giant sharks, enormous predatory insects, these are the things nightmares are made of. They appear in our nightmares for good reason, once upon
275: Run Your Car On Hydrogen Fuel
You may have heard of hydrogen powered cars before, but generally when they are referred to people think of "fuel cell" vehicles prototyped by different car manufacturers. There is another type of hydrogen powered vehicle, one that uses hydrogen not as a primary fuel, but supplementally. In fact, anyone can convert their existing car to run on the
276: Science Fair Research Made Easy
A thorough knowledge of your subject is the key to a successful project
A wealth of fascinating information on your topic area is as close as your local library. Use it!
Believe it or not, many beginning science fairers try to plan a project without really understanding the nature of their subject. As you might expect, the most complicated a
277: So You Think You Can Destroy Evidence With Fire
Criminals will go to almost any lengths to cover their tracks when they commit a crime that will send them to jail. Starting a fire deliberately will send them to jail also, but sometimes the act they committed will be worse than a fire. People have been using fire to destroy evidence and cover up crimes for hundreds of years or longer and probably
278: Solar Power Will Eventually Take Over The World
Solar power is useful because it generates peak power at the time there is peak demand (daytime), unlike wind energy (which often produces more at night than during the day). Nighttime demand is about half of daytime demand. Solar power is renewable as long as the sun keeps burning. Even with the sun expending 700 billion tons of hydrogen every sec
279: Some Of The Beneficial And Unusual Parasites
Parasites are bad for living organisms. Parasites are known to be bad for you because they will eat up all the nutrients in your body. They will cause malnutrition and diseases that may be fatal. Some parasites cause malaria, a very dangerous disease.
There are also parasites that live on the skin surface, like mites. Dog mites affect the skin a
280: Squids Attract Bacteria By Their Slime
If you have ever been inquisitive about the vast variety of creatures living in the depths of the blue sea, you must have discovered a plethora of creatures living underwater. The salmon on your plate, great white sharks, octopuses and squids are among the thousands of organisms that live under the sea. Unlike terrestrial animals, aquatic life is v
281: Technology Used In Astronomy Today
Astronomy is a topic in science. For most of astronomy, there are scientific instruments in use. These can be telescopes, which have different technologies, and also that of using computers. In this article, we will take a look at technology used in astronomy today.
Since the dawn of time, man has looked up at the stars in amazement. What were t
282: Telescope Buying Guide How To Buy A Telescope
Are you interested in astronomy? Wouldn't it be great, to really see, what all those shinning points of light are, in the night sky? Well, you can with a telescope, but how to buy a telescope? What do you need to get started in astronomy, and wouldn't it be great to have it all in an easy telescope buying guide, such as this article?
Well, you h
283: Temperature Sensors%3B A Brief Introduction
From the humble thermometer to advanced electrical heat recorders, temperature sensors are used for all manner of purposes in a disparate number of industries. The more advanced forms of contact measurement device are labelled as thermocouples and resistance temperature detectors or RTDs. The measurement of temperature typically takes place in liqu
284: Texas Braces For More ProtestorsThe Creation of Artificial Life Expected In Three To Ten Years
In three to ten years, expect the major announcement this country has been waiting for -- that artificial life has been officially created. Whether one is vehemently opposed to such technology, or believes it the greatest scientific breakthrough of the modern era, get ready.
Scientists in the obscure field of "wet artificial life" are making st
285: The Advantage Of Using Wind Energy
While some of these places are just starting up their wind farms and wind energy harnessing management, other countries have a fully molded plan to use this renewable resource to energy their homes and cities. With the price (and pollution levels) of traditional energy sources such as burning coal and other combustible resources being extremely hig
