When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

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

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 ...

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 ...

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 ...

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

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

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

RIVERSIDE, Calif. -- A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily. So for ...
