New twists on ancient DNA - October, 2019
DNA looks like a delicate molecule: a narrow twisted ladder, perhaps two inches long, but just two nanometers wide. What would it take to destroy such a thin chain of atoms? More than one might think! Researchers who study ancient DNA have so far managed to reconstruct genetic sequences from samples up to 700,000 years old! This past month, two new studies highlighted how we can squeeze even more genetic information out of ancient remains.
