Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells ...

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 ...

The DNA of Chernobyl cleanup workers showed mutations caused by radiation that were also evident in the genes of their ...

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we ...

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 ...

The prothrombin gene mutation increases your risk of severe blood clots. Medications, regular checkups, and healthy lifestyle habits can help reduce this risk. The prothrombin gene plays a crucial ...

What do your genes have to do with growing old? Quite a lot. But is it due to the actual DNA, or the way those genes are expressed? KPBS sci-tech reporter Thomas Fudge has more on new research that ...

Mitochondria are well known as the powerhouses of the cell because of their energy generating capabilities. These little organelles are very special, because they also carry their own tiny little ...

Researchers have refined a powerful DNA sequencing tool that can uncover hidden mutations that occur naturally in our bodies as we age. In the largest study to date, they have used the tool to provide ...

Domestic pigs bred with wild boar after the nuclear disaster offer lessons in wildlife genetics and invasive species management.
