Every day, our bodies perform around 330 billion cell divisions to keep us alive and functioning. These divisions rely on the cell cycle, which has been in place since the earliest bacteria. The ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

A fundamental question in biology is whether all cells age. Embryonic stem cells (ESCs) defy the norm as rare normal cells capable of indefinite in vitro passage. However, the mechanisms underlying ...

One of the most diverse ecosystems on the planet is closer than you think—right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in distinct, ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...
