Aging does not arrive all at once. It builds quietly across years, touching cells long before symptoms appear.

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

CRISPR is a powerful DNA-editing tool that has underpinned huge advancements in human health care in the last decade. It is a ...

The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...

A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...

Scientists at Cincinnati Children's have identified how certain immune cells are molecularly programmed to respond faster ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

In a new study in mice published on Thursday in Science, researchers showed how skin cells inherit patterns of gene ...
