Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of ...

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours - sometimes more than a day - in a ...

A research team led by UAB researcher David Reverter has discovered the molecular mechanism that describes in detail the ...

Cells in the human body accumulate cancer-promoting mutations throughout their lifespan, yet these mutations rarely drive tumour formation. Tumours in a given tissue usually originate from a specific ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...

If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during ...

The awe-inspiring process of cell division can turn a fertilized egg into a baby – or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process ...

It's long been assumed that when a parent cell divides into two daughter cells, the parent assumes a spherical shape, which then splits into two cells that have roughly the same, round size. But a new ...

New techniques to detect Y chromosome genes show frequent loss of the Y in tissues of older men. The increase with age is clear: 40% of 60-year-old men show loss of Y, but 57% of 90-year-olds.

What am I looking at? This is a time-lapse video showing the dynamic nature of the ER in monkey kidney cells as they undergo cell division. The density of the ER network is represented by the ...
