Genetic studies reveal a strange moment in human prehistory when male lineages nearly vanished, leaving only a small fraction ...

Researchers from Skoltech, the University of Potsdam, and the Massachusetts Institute of Technology have discovered a fundamental physical law that governs the seemingly chaotic motion of chromosomes ...

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, ...

The loss of the Y chromosome in tumour cells is linked to poor outcomes for people with cancer 1, but this genetic alteration might also compromise immune cells that would otherwise fight the disease.

Women, on average, live longer than men. This trend can be seen as far back as records stretch, and is true of every country in the world today. Many explanations have been put forward: men take more ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Brain cells, or oligodendrocytes (green), in the hippocampus are marked with the GFP genetic marker in the mouse brain. These cells often deteriorate during aging. Image credit: Gadek et al., Science ...

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro proof-of-concept study. Down syndrome is caused by the presence of a third copy of ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 chromosomes ...
