Human and Helicobacter co-evolution
by Denise Anthony (iStock) A Vanderbilt University-led research team has solved a long-standing riddle: Why do people of mostly Amerindian ancestry in the Andes have a gastric cancer rate that is 25 times higher than that of fellow Colombians of mostly African descent only 124 miles away on the coast?… Read MoreJan 23, 2014
