How are these unique sex chromosomes formed? "The sex of a somatic cell as highly differentiated as a neurone may be detected with no more elaborate equipment than a compound microscope following ...

UCSF researchers may have discovered how the female brain remains resilient in aging, answering an age-old question of how most women outlive men and retain their cognitive abilities longer. Females ...

It’s not just about chromosomes. Or reproductive cells. Or any other binary metric. Many genetic, environmental and developmental variations can produce what are thought of as masculine and feminine ...

Research suggests X and Y chromosomes may influence aging and disease risk, beyond determining biological sex.

Study in mice and human cadavers hints that a brain-protective gene in the chromosome becomes more active with age. Women tend to live longer than men and are often more resilient to cognitive decline ...

In a surprise, work in mice has found that the dormant X chromosome in females can reawaken late in life and turn on genes that keep the brain healthy. UCSF researchers may have discovered how the ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female brain from genetic diseases. Although one of the two X chromosomes is ...

Since ancient times, scientists and philosophers have pondered the fundamental question of what makes some organisms male and some female. Some hypotheses were at least plausible—Greek philosopher ...

Results provide framework for uncovering regulatory variants in other X chromosome neurodevelopmental genes that may ...

Researchers at Baylor College of Medicine identified MECP2 regulatory variants on the X chromosome that may help explain why ...
