A study finds that XIST, the gene that shuts down one X chromosome in people who have two, is linked to cancer in males. 

Evidence from various sciences reveals that there are diverse ways of being male, female, or both. An anthropologist argues that embracing these truths will help humans flourish.

About one-quarter of the hundreds of genes on the inactivated X chromosome in XX cells manage to escape that silencing, at least some of the time.

When X-linked genes evade silencing on the “inactive” chromosome in XX cells, some protect women from diseases such as cancer, but others seem to promote conditions such as autoimmunity.

A genomic analysis from 23andMe suggests that people inherit two copies of a chromosome from only one parent nearly twice as often as researchers had realized.

A quirk of nomenclature originates in the study of insect cells.

The Stanford University professor was known for his work on sex determination and courtship in flies.

A toothpick and a bit of chance shaped David Page’s career, which he has dedicated to understanding the mammalian Y chromosome and fetal germ cell development.
