Add Yahoo as a preferred source to see more of our stories on Google. Brain inflammation may be fueled by a gene on the X chromosome, a new study in mice suggests. And in female mice, who carry two X ...

Mutations in the X chromosome often cause intellectual disability, and women born with just one X chromosome (a diagnosis known as Turner Syndrome), can have cognitive impairments. X chromosomes, some ...

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 ...

Researchers from the University of California, San Francisco (UCSF) say they have now found that when the brain cells of female mice express only a maternal X chromosome, the animals’ memory and ...

In female mammals, one of the two X chromosomes is usually inactive and forms the so-called Barr body. The image shows a cell nucleus with the Barr body marked in green. Unlike men, who carry one X ...
