DNA News and Research

RSS

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).

TRF1 protein depletion linked to leaner mice and altered metabolism

A new research paper was published in Volume 17, Issue 9 of Aging-US on September 17, 2025, titled "Depletion of the TRF1 telomere-binding protein leads to leaner mice with altered metabolic profiles."

Prenatal air pollution exposure tied to higher autism risk in children

A population-based study of over two million births in Ontario found that prenatal exposure to the sulfate and ammonium components of fine particulate matter (PM₂.₅) was associated with a higher risk of autism spectrum disorder. The risk was greatest during mid to late pregnancy and among infants in urban, lower-income neighborhoods.

New gene-editing method can correct many disease-causing mutations in mammalian cells

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same disorder might have a different combination of mutations.
