Unveiling a new chapter in the understanding of human genetics, scientists have discovered a hidden geometric code within our ...

They observe how the mobile DNA LINE-1 copies its sequence in human cells, revealing the precise mechanism of the ORF2p gene.

Long interspersed nuclear element-1 (LINE-1 or L1) is the only active, self-copying genetic element in the human genome—comprising about 17% of the genome. It is commonly called a "jumping gene" or ...

DNA shines a light back into the past, showing us things that fossils can't. But how far back can that light extend? Some of the oldest DNA sequences come from mastodon and polar bear fossils about 50 ...
