WikiNews Installed MathJax extension
As described on the page of the extension this also adds the possibility to add references to the formulas.
Thanks to Oliver Borm for the suggestion.
As this library uses the same tags as the old mechanism for rendering math no changes to existing pages are required. Should you experience problems with existing formulas that seem to be due to the change please contact me
Update: Disabled the extension because of the problem described here (having environment variables like $HOME in the text breaks the rendering). Hints how to solve this problem are welcome. Once a fix to the problem is known the extension will be reenabled.
