Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

Each cell in our bodies carries about two meters of DNA in its nucleus, packed into a tiny volume of just a few hundred cubic micrometers—about a millionth of a milliliter. The cell manages this by ...

Our experiences leave traces in the brain, stored in small groups of cells called engrams. Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes ...

It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own version. Cornell researchers have discovered that DNA packaging structures ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

Experiencing multiple acute stresses at the same time, as in natural disasters or mass shootings, can leave lasting memory scars. New research from the University of California, Irvine suggests that ...
