This skull may have better teeth than you.
February 24, 2013 By examining ancient dental plaque, researchers have concluded that prehistoric humans' diets made for healthier mouths. The addition of flour and sugar to modern diets may have set the stage for a near-constant state of oral disease.

January 30, 2013 The bacteria that live in humans' guts influence weight gain and health. By studying twins in Malawi, scientists have found that changes in this microbial community may also turn malnutrition into a fatal condition.

January 16, 2013 Canadian scientists have developed a synthetic stool that successfully treated two patients with a severe form of diarrhea. The researchers call the concoction RePOOPulate, and they produce it using a machine that recreates conditions in the colon.
June 13, 2012 The human body contains about 100 trillion cells, but only maybe one in 10 of those cells is actually human. The rest are from bacteria, viruses and other microorganisms. Now, scientists have unveiled the first survey the "human microbiome," which includes 10,000 species and more than 8 million genes.

May 9, 2012 While U.S. adults have relatively uniform microbe colonies in their guts, adults in Malawi and Amazonia have much more diverse populations. Scientists are still struggling with why that is and what it means.
