DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

New research center brings advancements in genomic medicine to admixed individuals

One way to make health care more personalized is to use a person's DNA sequence -; or genome -; to predict their risk of disease. But as the field of precision medicine grows, so have concerns that we may be leaving a large fraction of Americans out.

Newly developed method helps refine the "Out of Africa" scenario

Researchers from Estonia and Italy developed an innovative method by combining neural networks and statistics. Using this newly developed method, they refined the "Out of Africa" scenario. The researchers claimed that the African dynamics around the time of the Out of Africa expansion are more complex than previously thought.
