One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.

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, ...

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

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. Now, ...

Biological science has made such astonishing leaps in the last few decades, such as precise gene editing, that scientists are now tackling the next logical — yet inherently controversial — step: ...

The Y chromosome, the male relation genetic signature, has been a mystery to scientists for centuries. It’s the most repetitive and complex region of the human genome, and never before was it possible ...

The images above depict artificially-derived neurons grown in petri dishes, with a human neuron shown on the left. Artificially-derived chimpanzee neurons grow only one or two neurites (connecting ...

The human Y chromosome, responsible for determining male sex, has been gradually shrinking over millions of years. This ...

Jenny Graves is a Friend of The Conversation. 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 ...
