As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the ...

We grow up hearing that our skin, hair, body shape, and even how we age are all written into our DNA. And yes—genetics leave ...

SEM images of male and female human aortic valve tissue samples from two healthy patients and two patients diagnosed with AVS. Scale bars, 5 micrometers. A study led by bioengineers at the University ...

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the chromosomal location of genes to natural selection, indicating the arrangement of ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

The evolution of sex chromosomes influences reproductive biology and genome evolution across species. In Drosophila pseudoobscura, the Y chromosome has a distinct origin compared to Drosophila ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't ...

The Y chromosome, carrier of male identity, is slowly fading away. Does its gradual disappearance signal the end of the human species? A recent discovery in Japanese spiny rats offers a glimmer of ...

Researchers have shed new light on how a type of heart valve disease -- aortic valve stenosis -- progresses differently in males and females. A study led by bioengineers at the University of ...
