The scientific evidence overwhelmingly supports the idea that all living things share a common ancestry. Charles Darwin, a British naturalist, is the person most remembered for his contribution to how the process of evolution works. He wrote a book, published over 150 years ago, called On the Origin of Species, which was very controversial at the time....

Cholera and other diarrheal diseases cause nearly 2 billion cases of diarrhea annually. Cholera toxin and other bacterial toxins cause the intestine to secrete fluid into the lumen of the gut, depleting the extracellular fluid (ECF) volume. If fluid loss is not matched with fluid intake (law of mass balance), the result is severe dehydration, circulatory collapse, and even death. Drinking a rehydration solution is the most rapid and effective way to replace the large volumes of water lost by...
