Scientists in Tokyo have uncovered “Inocles,” massive strands of extrachromosomal DNA hidden inside bacteria in human mouths. These giants, overlooked by traditional sequencing, could explain how oral ...

In a remarkable turn of events, scientists have stumbled upon non-human DNA from ancient fossils, shaking the very foundations of our understanding of human evolution and our ancestral lineage.

Every cell in the human body squeezes over six feet of DNA into a minuscule speck invisible to the naked eye—like compressing a whole house into a single sugar cube. In order to fit in a cell and ...

The bacteria that cause tuberculosis (TB) may have an "on-off switch" that lets them pause and restart growth, according to a new study from the University of Surrey and the University of Oxford. The ...

Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted “dual origins” theory. The ...
