Cause of Childhood Fears Can Be Elusive

Fear is a common reaction and may have a simple explanation. But some fears -- especially in children -- are complex, and the reasons are not always obvious. Children often fear dogs, the dark, school and costumed characters such as clowns or Santa Claus or even Mr. Peanut. Halloween can be a particularly frightening time for some children. “Children think that if it can happen, it will,” according to Joseph Crowley, Ph. D., a clinical child psychologist in Richmond. “They think differently than adults so they react differently.”

The Science Behind Sustainable Lawn Care

Who doesn’t like the look or feel of a freshly mowed, thick lawn? Some feel that in order to achieve the athletic field look there must be gallons of water, tons of fertilizer and several bottles of pesticide used. In some lawns, the answer is yes, but in most cases no. You can achieve the desired green look by following similar techniques used on college campuses, athletic fields and golf courses without using products in excess. Planning is the key to success in lawn care.

The ABCs of Winemaking

Winemaking requires a delicate balance of agriculture, biology and chemistry. Physics and engineering also have roles in producing good bottles of wine.

Wine is the fermented juice of grapes or other fruits. Grapes contain two types of sugar, glucose and fructose, and other chemicals like tartaric acid, malic acid and amino acids. This gives grapes the right balance of chemicals to help preserve the wine and make it taste good.
