Uncovering the Molecular Roots of Neural Stem Cell Decline

Age often brings a gradual decline in the ability to learn new things and retain memories. This phenomenon, often associated with the elderly, is linked to the brain's deteriorating capacity to generate new neurons-a process that primarily occurs in the hippocampus -as neural stem cells (NSCs) divide and mature.

How DNA Packaging Shapes p53 Activity

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.

New Computer Program Mimics Human and Animal Cell Behavior

Using mathematical analysis of patterns of human and animal cell behavior, scientists say they have developed a computer program that mimics the behavior of such cells in any part of the body.

Brain Cells Show Unexpected Self-Sufficiency in Energy Use

A new Yale study has revealed that neurons - the energy-hungry cells that connect and direct activity in the brain - are equipped with "backup batteries" that kick in to keep the brain running during periods of metabolic stress.

Brain Ripples Help Segment Experience Into Memories

A research team from the Faculty of Psychology at the University of Barcelona, the UB Institute of Neurosciences (UBneuro) and the Bellvitge Biomedical Research Institute (IDIBELL) has identified, for the first time in humans, and in a realistic environment, a key neurophysiological mechanism in memory formation: ripple-type brain waves -high-frequency electrical oscillations that mark and organize the different episodes or fragments of information that the brain stores as memories.
