Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

When Homo sapiens trekked out of Africa, our species encountered Neanderthal populations already inhabiting the vast expanses of Europe, Asia and the Middle East. As the presence of Neanderthal DNA in ...

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 ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Subscribe to ...

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...
