![[Tree of Life] The Wellcome Sanger Institute’s Tree of Life programme has announced ambitious plans to accelerate publication of genome notes from approximately 30 per month to 200, expanding access to research that is supporting advances in agriculture, conservation, and medicine. This significant increase will be facilitated by a new specialised workflow developed by F1000 and the Wellcome Sanger Institute for Wellcome Open Research.](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/treeoflife1-2.jpg?resize=1200%2C722&ssl=1)
