Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

Studying over 100,000 embryos revealed genetic factors behind chromosome segregation issues that lead to aneuploidy, ...

By studying genetic data from nearly 140,000 IVF embryos, scientists have with unprecedented detail revealed why fewer than ...

Despite being densely packed to fit into the nucleus, chromosomes storing our genetic information are always in motion. This allows specific regions to come into contact and thereby activate a gene. A ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

In 2002, evolutionary biologist Jenny Graves shared a controversial calculation. The human Y chromosome, she wrote two years later in a commentary, "is running out of time." The male-determining sex ...

Ancient DNA is turning human evolution into a crime scene reconstruction, and one of the prime suspects is a herpesvirus that ...

Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...
