Although fire ants originated in the U.S. as the result of "imports" from South America, their spread to many other countries is from the U.S., new genetic assessment shows

Fire ants are a royal pain (literally and figuratively). Chemical pesticides and many other brews have tried to wipe them out, unfortunately without success. They are now colonizing many other countries. But, what is the origin of these new invasions? The aggressive, stinging fire ants ( Solenopsis...

It has been long suspected, and more or less recently confirmed, that animals (particularly those that were domesticated thousands of years ago) are the source of many major human diseases, including diseases that ironically are no longer found in animals. See, for example, http://www.nature.com/nature...

More Studies are Focusing on the Types of Bacteria that are Part of all Humans

Prior posts have noted that a) for every 1 human cell there are 10 bacteria in or on our bodies; b) these bacteria are key to the digestion of our food, production of necessary nutrients, and disease prevention; c) the nature of our diet influences the make-up of bacterial colonies in our GI tract; d...
