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

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 ...

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 ...

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 ...

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 ...

Rosalind Franklin knew about DNA's double-helix structure ahead of Watson and Crick, a new study of her photos and notes ...

Scientists at the Montreal Clinical Research Institute (IRCM), led by Université de Montréal medical professor Javier Di Noia, have shed light on a fundamental mystery in immunology: How do immune ...

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 ...

On February 28, 1953, two scientists, James Watson and Francis Crick, announced they had figured out the structure of DNA. DNA or deoxyribonucleic acid, is the hereditary material in humans and almost ...

Over the past 50,000 years, many of the world’s large mammals have gone extinct. Until recent decades, all we knew about them came from fossils. Now, analysis of ancient DNA is adding to the picture.
