Ancient DNA analysis unlocks secrets of Ice Age tribes in the Americas Research

Scientists have sequenced 15 ancient genomes spanning from Alaska to Patagonia and were able to track the movements of the first humans as they spread across the Americas at “astonishing” speed during the last Ice Age, and also how they interacted with each other in the following millennia.

Only 12 percent of American adults are metabolically healthy, study finds

The prevalence of metabolic health in American adults is ‘alarmingly low,’ even among people who are normal weight, according to a new study from the University of North Carolina at Chapel Hill’s Gillings School of Global Public Health. Only one in eight Americans is achieving optimal metabolic health. This carries serious implications for public health since poor metabolic health leaves people more vulnerable to developing Type 2 diabetes, cardiovascular disease and other serious health issues.

Ancient DNA evidence reveals two unknown migrations from North to South America

An international research team has used genome-wide ancient DNA data to revise Central and South American history. Their analysis of DNA from 49 individuals spanning about 10,000 years in Belize, Brazil, the Central Andes, and southern South America has concluded that the majority of Central and South American ancestry arrived from at least three different streams of people entering from North America, all arising from one ancestral lineage of migrants who crossed the Bering Strait some time before 15,000 years ago.
