New Paper on the Journal of Errology

I am one of the founders of the controversial Journal of Errology, as announced and discussed online in another blog here.

Well, after a long while adjusting practical matters we received a number of submissions which missed the true scope of our journal, as detailed here.

Thus we decided to publish an inauguratory paper to inspire further authors. I am proud to announce that I wrote this paper on the matter of larval morphology, discussing one of my previously published papers, on the larvae of the Crazy Ant.

Well, a link to my inauguratory paper is given here. I will add an excerpt below. Please note that anyone can comment and share the paper, thus never hesitate to leave your impressions there.

"My first ant larval description was made with an invasive pest of planetary distribution, the crazy ant Paratrechina longicornis (Formicidae: Formicinae). In fact that was my third paper in life, and the first to be done without the assistance of some more experienced researcher. This summarizes why this account should be useful to readers of the Journal of Errology. I made a lot of mistakes yet in the end succeeded in establishing myself fairly in this area of study. I will report on difficulties with this paper mistakes and what I learnt from them."

Reviving this blog

I am really sorry for having been away for such a long long while. Writing many papers and getting many things going has really consumed my mind over the whole of last year. I will now slowly proceed to revive and reformulate this blog. It needs pictures. It needs links. It needs polemic issues. I will provide those, and hopefully I will get more visitors and comments.

Let us begin!

Fiery venom

Just killed an awesomelly huge fire ant nest (invicta) in UFRJ, Rio de Janeiro. Am finished extracting the venom, really loads of, suspected 2g of venom alkaloids!! They are quite yellow, I dont get why other authors elsewhere claim they are colourless....

Anyone has a hint?

New developments, new insights

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.

Amazing results of fire ants venom

Impressive. The imported fire ant has apparently five times as much venom protein as the other "less severe" Brazilian native species. ...and, I reckon, they are the exactly same proteins!

This ought to have unfathomable implications. Once I confirm this, my papers will speak for themselves. 

Amazing!
