Plasma is one of the four fundamental states of matter (the others being solid, liquid, and gas). Heating a gas may ionize its molecules or atoms (reducing or increasing the number of electrons in them), thus turning it into a plasma, which contains charged particles: positive ions and negative electrons or ions.

In 1989, retailers warned that sales in West Virginia would go down if legislators imposed a 6 percent tax on food. "Whatever they put on would be passed on to the consumer," Charles Forth, who owned supermarkets in both West Virginia and Ohio, told the newspaper in February 1989. "Six percent is $6 on $100. That will make a difference when people are already hurting and trying to make ends meet." It's a lot easier to drive customers away than to win them back, a fact legislators should bear in mind when it comes to taxation.

The Scientific Services Bureau operates one of the largest full-service crime laboratories in the United States. A staff of 198 members provides forensic science support to all Los Angeles County law enforcement agencies, except the Los Angeles Police Department.
