... neurochemical atrophy in the brain at all. Furthermore, it should be noted that Heath's work was sharply criticized for avoiding safeguards of bias and reporting "changes" that occur normally in the mammalian brain. Wu et al. found a correlation between cannabis use and low sperm counts in human males. This is misleading because a decrease in sperm count has not been shown to have a negative effect on fertility and because the sperm count returns to normal after cannabis use has stopped.. Another claim made was that cannabis causes chromosome breakage. The primary source for this are studies that were ...

Atoms
Number of Words: 520 / Number of Pages: 2
... John Thomson discovered electrons.
Using a tube, magnets and charged plates, he sent ray particles through
various experiments changing the position of the charged plates. By
changing the plates, he discovered he could also change the point at which
the particles would hit a florescent screen at the end of the tube. He
decided that the ray was made up of particles with a negative charge. He
named these particles electrons. This discovery also showed that atoms had
a substructure. Thomson made a model showing his idea for the atom. His
model, called the raisin dough model had positive and n ...

The Beginning of Microbiology
Zacharias Jansen created the microscope. Although Robert Hooke is
the one who made it widely known. In 1665 Hooke published a book called
Micrographie. It contained his thoughts on chemistry as well as a
description and list of uses for a microscope. With this he opened the
door to microbiology.
For the first time the world was able to see very small creatures
and objects. From the use of a microscope he was able to make drawings of
the structure of a feather, the eye of a fly, the stinger of a bee, and the
plant-like form of mold. And from his ...

Electric Charge

... not move. Charges on an object are called static electricity to contrast then with the moving charges in an electric current.
How can you disturb the balance of charge on objects so they exert electric force? The easiest way is the same way the ancient Greeks did it – by rubbing the 2 objects together. Rubbing neutral objects together allows charged pieces of matter to move from one object to another.
The invisible bits of negatively charged matter that move between objects are called electrons. The words electron, electricity, and electronics all come from the Greek word for amber – el ...

... lives beneath the Earth's icy polar tundra's in the arctic
and Antarctic. George W. Wetherill even notes that “Even if a planet or
moon could not support life globally, each could contain a tiny niche where
life could thrive” (Science News, 328).
What are the most favorable conditions for life to develop? It is
now known that life simply cannot emerge anywhere that does not contain
water. It is mostly preferred that this water exists in liquid form, but

conditions. Water and energy, which both exist in many places in outer
space ...

... there will never be a perfect balance or “mixture”, what is the point of even trying? Maybe they are right in saying that we will never find the perfect mixture, but this negative attitude is part of the problem. Nothing will be accomplished unless we reject apathy and negativity.

... who use their knowledge for evil, are rampant on the Internet. Sometimes they do seemingly harmless acts, such as just going into a computer system and observing, but at other times, they steal, destroy or alter data. On some occasions, these cyber-felons perform even more malicious acts, such as infecting systems with "viruses," computer programs that "infect" the systems by latching onto other programs and eventually destroying them. Another favorite activity of the hacker is to gain access to the computer system and then manually either delete files or cause the computer to do "strange" things, suc ...
