Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

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 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 ...

For sexual reproduction to yield healthy offspring, newly generated oocytes-immature egg cells-must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

In a major leap forward for genetic and biomedical research, two scientists at the University of Missouri have developed a powerful new artificial intelligence tool that can predict the 3D shape of ...

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 ...

WASHINGTON (AP) — Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive. But the experiment ...
