Been away for quite a while...
Much happened lately, mainly end-of-doc-thesis procedures.
Getting straight to facts, some exciting new developments on the fire ants surfaced:
1) Just heard the genome for invicta is on its late stages of development
2) Our latest venom analysis disconfirmed my previous expectations, the venom proteins of invicta are indeed quite different from saevissima.... and much more diverse! We are currently attempting to get to gram-amounts of pure saevissima neurotoxin, and get it sequenced.
