Soil water status as a function of pressure (tension). Soil water status in natural soils can range from a flooded. condition to drainable gravitational water to plant available water. down to hydroscopic water. Tensions in natural soils do not. exceed -31,000; in this range, water is absorbed from the air.

Tay-Sachs disease is a rare disorder passed from parents to child. In the most common form, a baby about 6 months old will begin to show symptoms. Tay-Sachs disease results when an enzyme that helps break down fatty substances is absent. These fatty substances build up to toxic levels in the child's brain and affect the nerve cells. As the disease progresses, the child's body loses function, leading to blindness, deafness, paralysis and death. There is no cure for Tay-Sachs disease. Gene therapy or enzyme replacement therapy research may eventually lead to a cure or treatment to slow the progression of Tay-Sachs disease.
