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).

Cell-free DNA circulating in the blood may signal early signs of dementia and frailty

In a long-term prospective study of more than 600 older participants, Johns Hopkins Medicine researchers say they have evidence that higher levels of cell-free DNA circulating in the blood may signal increased risk of chronic inflammation associated with early signs of frailty and dementia.

Light-Seq technology for barcoding and deep-sequencing selected cell populations in tissues

Under the microscope, researchers often observe different cell types organizing themselves in peculiar patterns within tissues, or sometimes a rare cell type that stands out by occupying a unique position, exhibiting an unusual shape, or expressing a specific biomarker molecule.

Men are biologically older than women, study finds

A study at the University of Jyväskylä found that men are biologically older than women. The observed sex difference is partially explained by men's more frequent smoking and larger body size.

Age plays a more important role than genetics in affecting gene expression profiles as we get older

Amid much speculation and research about how our genetics affect the way we age, a University of California, Berkeley, study now shows that individual differences in our DNA matter less as we get older and become prone to diseases of aging, such as diabetes and cancer.

NEI researchers create a high-resolution map of retinal cell chromatin contract points

National Eye Institute researchers mapped the organization of human retinal cell chromatin, the fibers that package 3 billion nucleotide-long DNA molecules into compact structures that fit into chromosomes within each cell's nucleus.

Research identifies new clue for preventing and treating gliomas

An important new clue for preventing and treating brain tumors known as gliomas has been identified in research led by the Lunenfeld-Tannenbaum Research Institute (LTRI) at Mount Sinai Hospital in Toronto and Mayo Clinic Comprehensive Cancer Center and Mayo Clinic Center for Individualized Medicine.

Study uncovers how the TAZ protein protects hematopoietic stem cells from aging

A well-functioning immune system is essential for protection against infections. However, with increasing age, the functioning of the immune system diminishes, which is also due to age-related damage in hematopoietic (blood) stem cells.

Researchers take new approach to studying the development of the human brain

Researchers at ETH Zurich are growing human brain-like tissue from stem cells and are then mapping the cell types that occur in different brain regions and the genes that regulate their development.
