In a new study, scientists probed the ways in which the X chromosome may change with age and affect cognition. . | Credit: ...

The New Science of Nature and Nurture.” Since Francis Galton coined the phrase “nature versus nurture” 150 years ago, the debate about what makes us who we are has dominated the human sciences. Do ...

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

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 ...

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

Again, fraternal twins are not identical and do not share the same chromosomes and genes. Can fraternal twins have different fathers? Created with Sketch. When a woman hyperovulates, or releases ...

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

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.

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 ...

For one, inserting at the end of the chromosome helps the transposon avoid genes for the cell's core functioning, which reside in the middle of the chromosomes; transposons that can target the ...
