After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres—the protective ...

A hallmark of cancerous cells is an abnormal number of chromosomes or chromosome arms, known as aneuploidy. While aneuploidy ...

Scientists have uncovered an unexpected function for a crucial protein involved in cell division. Reported in two consecutive ...

Telomeres — the protective caps at the ends of chromosomes — function like molecular clocks, shortening as cells divide and age. When they become too short, cells stop replicating, accelerating aging ...

Women have risk factors such as genetics, hormones, and sex-specific responses to stress.

Men are from Mars, and women are from Venus—or so the saying goes. While this may be a generalization, there’s no doubting ...

Activists quietly shifting the goalposts on sex-and-gender discussion to escape the fact that they're losing the biology of ...

Tatiana Schlossberg, the youngest granddaughter of President John F. Kennedy, recently revealed she was diagnosed with ...

Single cell imaging of senescent cells (which usually do not divide) undergoing multiple divisions after ATM inhibition-their ...

In bacteria, the two defining processes of the cell cycle, chromosome replication and segregation, progress hand in hand. The roles of the enzymes and proteins involved in chromosome replication have ...
