GONUTS has been updated to MW1.31 Most things seem to be working but be sure to report problems.

It is now the 2nd CHALLENGE Period for CACAO Spring 2020! It will end on Sunday February 23, 2020 at 11:59 pm CST
This is your chance to challenge other team's annotations. You may also DEFEND or suggest improvements to your own annotations IF they have been challenged. Please note, although we ENCOURAGE challenges, an excess of identical challenges that do not appear to be applicable to the annotation or well thought out will be considered spam and ignored.

Past Semesters



We ran a pilot competition in the Spring of 2010 with 20 volunteer undergraduates from Texas A&M University.  This was run on our sister site, EcoliWiki.

After the initial test-run and a lot of positive feedback from the students, the competition was set up as a multi-national competition in the Fall of 2010 with the addition of teams from University College London

UCL CACAO team Fall 2010 (l-r) - Ruth Lovering (instructor), Amy Hong (Team UCL1), Coralea Stephanou (Team UCL1), Dipali Patel (Team Firefly), Athina Dritsoula (Team Firefly), Louisa Steel (Team Firefly) & Varsha Khodiyar (instructor)

The University of Central Florida has entered a bacterial genetics class of 54 students. Texas A&M, U. of North Texas, U. of Wisconsin-Parkside, North Dakota State and Michigan State are competing again this semester with UWP entering 2 courses. In all, there are more than 150 students competing this semester. They are under the careful supervision of a group of CACAO biocurators from Texas A&M consisting of either undergrads who have already completed CACAO at least once or grad students. We refer to these students as "CACAO II" and they are helping to make CACAO easier to scale up.
