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 ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

The 'silent' X chromosome within female brains may not be so silent after all. A new study has found evidence in both mice and humans that as we age, 'sleeping' X chromosomes can be 'awakened' in ...

Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...

Male mouse fetuses can develop female organs in utero if their mother is iron deficient during pregnancy, a study in Nature reports 1. This is the first-known example of a dietary mineral affecting ...

X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active (blue). A ...

Scientists have long tried to unlock the secrets to helping people live longer at the cellular level, where aging occurs because of the gradual shortening of protective caps called telomeres at the ...

A surprising finding from researchers in Japan has shown how an environmental factor can influence the development of sex organs in unborn mice. The discovery challenges the longstanding belief that ...
