An international team of researchers has discovered two networks of genes across all types of rockfish that may help to explain the differences in longevity in different species. In their paper published in the journal Science ...
A beating heart, a complicated organ that pumps blood around the body of animals and humans, is not exactly something you associate with a Petri dish in a laboratory.

Despite the sheer number of genes that each human cell contains, these so-called "coding" DNA sequences comprise just 1% of our entire genome. The remaining 99% is made up of "non-coding" DNA—which, unlike coding DNA, does ...

There are many genes, or at least markers of one sort or another within our DNA sequences, that have been associated with height. By some estimates the number could be thousands. However, finding those select genes that have ...
A paper in Nature proposes a new evolutionary scenario that helps to better understand the evolution of our phylum and to discover what the ancestor of tunicates—the sister group of vertebrates—were like. Specifically, ...
