Everyday DNA mutations can help us understand immune function and aging—and even mitigate harm caused by some inherited ...

A new microfluidic chip simplifies detecting and quantifying DNA by analyzing electrical impedance signals that vary based on DNA flowing across a biosensor inside the chip. The proof-of-concept ...

Circulating tumor DNA (ctDNA), small pieces of DNA released from dying tumor cells into the bloodstream, can be easily and non-invasively identified and examined through a simple blood test. This ...

A new gene-editing technique enables the correction of multiple genetic mutations simultaneously, transforming the prospects for millions living with complex inherited diseases, such as cystic ...

Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...

A reanalysis of whole-genome data from 130 children conceived after the Chernobyl disaster has identified a statistically significant increase in a specific type of DNA mutation in the offspring of ...

The microbial toxin colibactin has just the right shape to snuggle up to DNA — but its embrace is unfortunately more cancerous than cozy. Colibactin is produced by bacteria in the gut and causes ...

Genes are short sections of DNA that determine an animal’s traits—everything from coat color and claw strength to body shape and health. But sometimes, these genes mutate. And while the word itself ...
