A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop.

How a Scientific Revolution is Rewriting Their Story is its starting point, specifically, determining where it was. He hopes ...

In a quiet corner of eastern China, nestled between the Tai-Yi Mountains and the Bohai Sea, a discovery has upended ...

Researchers mapped Y chromosome loss across thousands of individual cells from human cancers, with disturbing results.

Nerves look blue in the reconstructed view of a genetically engineered mouse (left) whose neurons produce a fluorescent ...

Scientists have discovered that the Y chromosome, crucial for male development, is gradually disappearing. This loss, occurring in some men's cells around age 50, is linked to increased risks of ...

The monotreme sex gene may have been found after decades of searching – and it’s not what anyone expected.

Superman syndrome, also known as 47, XYY, is a condition in which males have an additional Y chromosome.

This study reveals the step-wise establishment of nuclear speckle-associated domains (SPADs) during mouse embryogenesis.

Scientists are expressing concerns about male reproductive health due to the Y chromosome's genetic material loss, potentially disappearing in 11 million years. A study revealed a sharp decline in ...

Flip open a high-school biology textbook, and the rule seems tidy: two X chromosomes mean girl, and an X paired with a Y means boy. That much smaller Y chromosome carries the SRY gene, which is the ...
