Mysterious sequences buried in our genetic code are being found to have unexpected effects ...

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 ...

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart ...

During cell division, a safety mechanism called the NoCut checkpoint helps delay the final stages of division when DNA bridges are present. The researchers found that this delay allows ESCRT-III ...

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 ...

Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help ...

Clues emerging from DNA could unlock the mystery of human ancestors that are missing from the fossil record yet present in the genes of people living today. Scientists found evidence years ago that ...

Two mysterious human relatives left their genetic footprints in the modern human genome alongside the DNA of Neanderthals and Denisovans, underscoring the fact that our ancestors interbred with many ...
