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 ...

A mixture of DNA and proteins—known as "chromatin"—sits inside every cell nucleus as a jumbled puddle of genetic information. As cells prepare to divide during mitosis, the chromatin is condensed into ...

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 ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter lifespans.

A large study published Jan. 29 in the journal Science suggests genetics could account for as much as 55% of a person’s lifespan. That’s far higher than earlier estimates, which ranged from 6% to 33%.

Researchers 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 produce enough ...

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 ...
