A small blood gene difference made Neanderthal pregnancies with modern humans risky, possibly contributing to their disappearance.

Organelles spit out DNA contaminated with damaging components, leading to the activation of inflammatory enzymes, mouse experiments show. Scientists found that, in the cells of ageing mice with kidney ...

Research led by the Max Planck Institute for Biology of Aging in Cologne reports that misincorporation of ribonucleotides into mitochondrial DNA (mtDNA) initiates an inflammatory cascade. Mitochondria ...

You can always be judged by your scars. This is the idea that sums up what researchers at Spanish National Cancer Research Centre (CNIO) claim is one of the new breakthroughs in basic and biomedical ...

Spanish scientists learned that warmer conditions scramble the DNA inheritance patterns in lizards that live in Madagascar and Australia, which makes it harder for these animals to pass healthy genes ...

Some genetic disorders—such as cystic fibrosis, hemophilia and Tay Sachs disease—involve many mutations in a person's genome, ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

Iron deficiency anemia occurs when there are insufficient red blood cells due to a lack of iron. In some cases, iron deficiency anemia can be genetic, as people can pass genetic variations onto their ...
