Escherichia coli (E. coli).
Waterborne bacterial infections account for 2-3 billion episodes of diarrhea resulting in 1-2 million deaths a year. The deaths tend to be of infants and young children from dehydration, malnutrition, and other complications of waterborne bacterial infections. At high risk are the two billion people living in poverty in the developing world. Some people in the US (in periurban “colonias” and remote rural areas with poor water treatment and delivery systems) are also at risk.
Contaminated surface water sources and large poorly functioning municipal water distribution systems contribute to transmission of waterborne bacterial diseases. Chlorination and safe water handling can eliminate the risk of waterborne bacterial diseases. But centralized water treatment and distribution systems are expensive and take years to complete.
To provide people with potable (safe drinkable) water in the short term requires innovative practical solutions such as point-of-use disinfection and safe water storage vessels. Electrolytic generators that produce sodium hypochlorite from salt water are now affordable and available for use in the developing world. Villages that produce and use sodium hypochlorite and store treated water in vessels to protect it from recontamination have had nearly 50% reductions in diarrheal disease incidence for pennies per family.
A fruit of African origin that is, in reality, a vegetable related to cucumbers and squash. Watermelon is 92% water and 8% sugar. It is rich in lypocene, an antioxidant that gives it its characteristic color. It is fat free.

“Your discovery of the molecular structure of the deoxyribonucleic acid, the substance carrying the heredity, is of utmost importance for our understanding of one of the most vital biological processes. Practically all the scientific disciplines in the life sciences have felt the great impact of your discovery. The formulation of double helical structure of the […]
- Wax dip
A treatment for the symptoms of joint and muscle conditions, such as arthritis, that consists of melted mineral wax derived from petroleum applied to a body area. Wax dips can be especially helpful in relieving the pain and stiffness of arthritis involving the small joints of the hands when used as a small bath. The […]
