DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Study Links Brain Epigenetic Changes and Tau Accumulation to Alzheimer's Pathology

Scientists know that age is the greatest risk factor for Alzheimer's disease, but aging alone doesn't explain why some people develop the condition while others do not.

Three-Dimensional Genome Architecture Actively Dictates Phenotypic Novelties in Octopuses

Octopuses, squid and cuttlefish, collectively known as coleoid cephalopods, have evolved exceptionally large and elaborately structured nervous systems capable of complex behaviors such as problem-solving and rapid camouflage.

Epigenetic DNA Methylation Clocks Track Gradual Cellular Rejuvenation Across Fifty Days

Researchers from the University Hospital of Bonn and the University of Bonn have succeeded in dramatically rejuvenating human cells in a test tube. To do so, they directly reprogrammed red blood cell precursors into stem cells from which neurons can be derived. During this process, the molecular clocks that indicate a cell's age were reset.

Transposable Element Methylation Instability Impairs Overall Genomic Regulation in Large Breeds

Why do large dogs tend to live shorter lives than their smaller counterparts? According to a new study of nearly 900 dogs, the answer may be written into their epigenome. The findings reveal that larger and male dogs undergo accelerated molecular aging, with pronounced DNA methylation (DNAm) on the X chromosome and at transposable elements (TEs).
