Large Scientific Collaborations Aim to Complete Human Genome
Brianna Chrisman and Jordan Eizenga | Sep 1, 2022
Thirty years out from the start of the Human Genome Project, researchers have finally finished sequencing the full 3 billion bases of a person’s genetic code. But even a complete reference genome has its shortcomings.

First Human Genome Sequenced from Ancient Pompeii
Alejandra Manjarrez | May 26, 2022
The genome is from a male who was likely in his late thirties when the historic Mount Vesuvius eruption occurred. The analyses suggest he is related to the diverse Imperial Roman population of the time, and that he may have suffered from spinal tuberculosis.
