Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

Two decades after the human genome sequence was completed, researchers have finally finished a map of the piece that makes males distinct. The Y chromosome is what distinguishes biological males from ...

Scientists now believe the Y chromosome, found in males, plays a bigger role in health and aging than once thought. Earlier, ...

The ape sex chromosomes have now been fully sequenced. Rapid evolution has led to extreme differences in the Y chromosome between species, whereas the X chromosome experienced much less dynamic ...

South Korea’s national radiation research institute screened 80 North Korean defectors for signs of past radiation exposure ...

In what might be a surprise for some, the male sex chromosome is far more complex than its female counterpart. This is why it’s taken scientists so long to work out exactly what makes a male a male.

For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

Hermit crabs have the most chromosomes of any animal, with 254. Chromosomes carry genetic information in the form of DNA. Genes located on autosomes determine the inheritance of physical traits. Sex ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive ...
