From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...

A research group led by the University of Osaka has discovered that the DNA repair enzyme Polβ plays a crucial role in protecting the developing brain from harmful mutations. The study found that a ...

Researchers have discovered a mechanism in DNA that regulates how disease-causing mutations are inherited. The team identified two enzymes that regulate a chemical modification, 6mA, in mitochondrial ...

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 ...

Many scientific discoveries are serendipitous—the result of chance. Seeing evolution in action in a cheese cave turned out to ...

Bowel cancer cells have the ability to regulate their growth using a genetic on-off switch to maximize their chances of survival, a phenomenon that's been observed for the first time by researchers at ...

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might ...
