The first study to compare the accumulation of mutations across many animal species has shed new light on decades-old questions about the role of these genetic changes in aging and cancer. Researchers from the Wellcome Sanger ...

Healthy human cells have two (diploid) sets of chromosomes. However, it may also happens that cells have a tetraploid (quadruple) set. Usually, they do not divide further and die, but some cells can escape this fate. An international ...

New mutations occur at increasing rates in the mitochondrial genomes of developing egg cells in aging rhesus monkeys, but the increases appear to plateau at a certain age and are not as large as those seen in non-reproductive ...

Like disease in humans, parasites can wage a deadly evolutionary "arms race" against their hosts, even driving small populations to extinction if they mutate more quickly and gain the upper hand.

More than 50 years ago on the shoreline of a rocky tide pool, the US ecologist Robert Paine discovered that the removal of a single species from an ecosystem could dramatically alter its structure and function. He had discovered ...

The p53 protein protects our cells from cancer and is an interesting target for cancer treatments. The problem is, however, that it breaks down rapidly in the cell. Researchers at Karolinska Institutet in Sweden have now ...
