From Geosphere to Biosphere Session
July 2025

WORM Energy Supplies at Goldschmidt Prague!

Thank you to everyone who attended talks at the "From Geosphere to Biosphere" session. Grayson Boyer and Kate Weeks gave talks that involved quantifying microbial energy supplies with the WORM Portal. Check out the WORM Library tutorials 3-9. Energy Supply Calculations on the WORM server to learn how to do it with hands-on examples!

New Activity Diagram Tutorials
June 2025

New Activity Diagram Tutorials

Five new tutorials have been added to the WORM Library showing how to create publication-ready activity and predominace diagrams. Try them yourself on the WORM server through the WORM Library: tutorial 2-2. Activity Diagrams.
