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 ...

Scientists achieved a genetic breakthrough by removing an extra human chromosome using gene-editing technology. This landmark study successfully deleted the surplus chromosome 21 responsible for Down ...

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 ...

Our genome isn’t as peaceful as it looks—some DNA elements are constantly trying to disrupt it. Scientists studying fruit ...

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, ...

The findings shed new light on human reproduction and suggest pathways for developing treatments to lower the risk of ...

TORONTO - Scientists at The Hospital for Sick Children (HSC) have compiled the complete DNA sequence of human chromosome 7 and decoded nearly all of the genes on this medically important portion of ...

In Lewis Carroll's "Through the Looking-Glass," Alice is stuck in a never-ending race with the Red Queen yet never gains a ...
