Cranial Electrotherapy Stimulation (CES) is a treatment for brain disorders that has actually been around for quite some time. This is a non-invasive method of altering brain functioning by using small amounts of electricity. The general idea behind this technology is that you attach a clip to each of your earlobes and then allow a 80 to 600 microAmpere current to pass through. This is a very tiny amount of electricity and the only thing a person feels is a slight tingling feeling in their ears. This can be performed on a person while they are fully awake and has few side effects in comparison to the more drastic electroshock. This treatment has been shown to improve several different brain based disorders such as depression, insomnia and anxiety.

Researchers are not totally clear on how this device works, but it appears to have an overall stimulating effect on the brain. It may alter various mood regulating neurotransmitters such as serotonin and dopamine. It may also release endorphins, the brain’s feel good chemical. Recently researchers have tested CES on patients with generalized anxiety disorder. Generalized anxiety disorder is characterized by chronic worry and apprehension, often for no apparent reason. The researchers found that CES showed promising results and there was a significant decrease in anxiety scores in those who were getting the real treatment as opposed to the sham treatment.

Scientists have also tested this device in those with spinal cord injury. They found that CES was able to significantly reduce pain in those with this type of injury. So CES may be able to help those who currently have unmanigable pain. They have also tested it in patients with fibromyalgia and found that patients reduced the amount of pain they felt and increased their well being with this treatment.

The best evidence for CES as a treatment is for depression and insomnia. When compared to antidepressants, CES has a greater mood altering boost than almost any currently marketed antidepressant. The improvement above and beyond the placebo response is a little over 60 percent, while for antidepressants it is usually under 30 percent. So CES may be a powerful mood booster when compared to most other drugs. It is also a cheaper alternative than drugs and costs less over the course of a year than antidepressants. This treatment has also helped those with insomnia sleep better than those treated with sham CES.

So overall, cranial electrotherapy stimulation is an effective way to alleviate many brain based disorders. It has a proven efficacy for depression, insomnia and anxiety. It may also have other beneficial properties such as reducing pain.

How Do Telescopes Help Scientists?
By Koz Huseyin

Astronomy is one of the oldest of sciences. Since the dawn of time, men and woman have looked up at the heavens for answers. So, how does a telescope help scientists today? In this article, we will look at how does telescopes help scientists.

Science is made up of many legs. For example, we have biology, which deals with life, while engineering is designed to look into the mechanics of things. And we have astronomy, telescopes, and astrophysicists, all in a great work of taking humanity forward.

Now, we need to look at the question how does telescopes help scientists and science? The real answer we seek is how telescopes and astronomy helps humanity, because we have seen that astronomy is a science, and telescopes are scientific instruments.

So, how does telescopes help scientists, and ultimately humanity? Since the dawn of time, one of the first things that man must have done was to look up at the heavens. For centuries people have always wanted to know what the future holds. Here astronomy has been the basis of astrology. Though, some people may disagree, with this point. In either case, you likely have heard of astrology, and likely even know your own star sign!

On a practical note, telescopes have helped scientists in many ways. For example, telescopes are helping with monitoring the meteors and asteroids, which potentially could pose a threat to Earth. Here is a very practical application, because advanced knowledge may allow us to do something!

Another way is with the Sun. At times our Sun emits Solar flares, and these flares are so powerful, that they can cause problems on Earth. It has happened where the Solar flares have cause brownouts in some areas.

Some scientists have said that some asteroids and meteors may contain precious items, such as gold, diamonds, etc. These could be very valuable for humanity, and our progress forward. The telescopes help scientists find this information out, however, not with normal telescopes.

A telescope is used to see objects far away, but we often think of telescopes as scientific instruments, we look through and get an image, through some optics. As an example, the Hubble Space Telescope, though it is a telescope, it has no optical parts, people can look through. Instead images are taken and transmitted back for viewing.

A more practical way where people are benefiting from astronomy, and telescopes, is with the knowledge of how to put a satellite into space. This has made a big impact, and you almost likely have a cell phone, which utilizes satellites.

Another is with GPS technology, which allows you to know where you are. And now, we have technology, such as a Tom-Tom, which allows you to drive without the need of looking at a map in a book!
