Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the ...

Early in development, one of the two X chromosomes in female cells is inactivated — coated in various proteins and RNA molecules that prevent its genes from being expressed. Which one is ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.

Scientists discover that women's second X chromosome awakens later in life, expressing genes that protect the brain from ...

Researchers found that a gene on the Y chromosome influences how aortic valve stenosis progresses differently in males and ...

Researchers have shed new light on how a type of heart valve disease—aortic valve stenosis—progresses differently in males and females. The research paves the way for treatments that can be tailored ...

The research reveals that this sex-based difference can be traced to a gene on the Y chromosome. The discovery, published in Science Advances, not only showcases the critical need to understand ...

Transposons, or "jumping genes"—DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of antibiotic resistance. Cornell ...
