Our experiences leave traces in the brain, stored in small groups of cells called engrams. Engrams are thought to hold the ...

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 ...

Understanding how cells turn genes on and off is one of biology's most enduring mysteries. Now, a new technology developed by chemist Brian Liau and his collaborators at Harvard offers an ...

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 ...

Researchers have shown for the first time that flipping an epigenetic “switch” in specific memory-holding neurons can directly alter memory strength.

What happens when you squeeze DNA? Can pressure reveal something about how our genetic material is packed, protected, and accessed? Dr. Kushol Gupta, a structural biologist at the University of ...

Atomic force microscopy images show hepatitis B DNA in its natural state (left) and a zoomed-in look at how it wraps around human histones during an infection (right). Disrupting this process in an ...
