New techniques to detect Y chromosome genes show frequent loss of the Y in tissues of older men. The increase with age is clear: 40% of 60-year-old men show loss of Y, but 57% of 90-year-olds.

Chromosomes are tiny, filamentous structures in the cell nuclei of living beings. They contain genes with genetic information, for example, related to the development or control of diseases. Every ...

As men age, many quietly lose the Y chromosome in some cells, and scientists now link this hidden change to heart disease, cancer and even shorter lifespans.

A group of Chinese scientists has created powerful new tools that allow them to edit large chunks of DNA with incredible accuracy—and without leaving any trace. Using a mix of advanced protein design, ...

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...
