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).

Low levels of hydrogen peroxide can slow down cell aging

High levels of reactive oxygen species, called oxidants, are detrimental to cells in all organisms and have been associated with ageing.

Researchers show how encapsulated viruses hijack biosynthetic pathways in cells

Researchers from the Universities of Melbourne, York, Warwick and Oxford have shed light on how encapsulated viruses like hepatitis B, dengue and SARS-CoV-2 hijack the protein manufacturing and distribution pathways in the cell - they have also identified a potential broad spectrum anti-viral drug target to stop them in their tracks.

Novel computational method quantifies the coordination level between different genes

Although all humans share similar changes during aging such as gray hair, wrinkles, and a general decline in function, aging is considered to be the result of a cellular wear-and-tear process due to accumulated random damage, such as genetic mutations or DNA structural damage.

4 Nov 2020

Computational method reveals a new hallmark of aging

While all human beings share changes during aging, like wrinkles, gray hair, and a general drop in function, aging is assumed to be the outcome of a cellular process.
