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

Researchers have found a molecular mechanism that prevents multiplication of potentially dangerous cells by measuring the duration of mitosis. They have shown that this mechanism -- the Mitotic ...

Viruses insert “transposable elements” into the genetic material of host cells to replicate. While cells’ defense mechanisms have learned to silence most of these viral insertions, a few “jumping ...

Amino acids are required for cell growth and proliferation, but it remains unclear when and how amino acid availability impinges on the proliferation-quiescence decision. Here, we used time-lapse ...

Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study published April 9 th in ...
