DNA has been storing vast amounts of biological information for billions of years. Researchers are working to harness DNA for archiving data. A new method uses light to simplify the process.
New research is uncovering that whales have their own distinct microbiomes that may play important roles in animal health. But how do scientists study whale microbiomes?
Advances in DNA sequencing will help people to learn more about their ancestry.

Developments in mitochondrial DNA sequencing are returning South Africa’s slavery heritage to view.
Of more than 500 species of sharks in the world’s oceans, scientists have only sequenced a handful of genomes – most recently, white sharks.
