"Exploding" Termite Species Discovered
ananyo writes "A species of termite found in the rainforests of French Guiana takes altruism seriously: aged workers grow sacks of toxic blue liquid that they explode onto their enemies in an act of suicidal self-sacrifice to help their colonies. The 'explosive backpacks' of Neocapritermes taracua grow throughout the lifetimes of the worker termites, filling with blue crystals secreted by a pair of glands on the insects' abdomens. Older workers carry the largest and most toxic backpacks. Those individuals also, not coincidentally, are the least able to forage and tend for the colony: their mandibles become dull and worn as the termites age, because they cannot be sharpened by moulting (abstract)."
This kind of suicidal defence using bodily fluids is not unheard of among certain termite species.
I laughed.
But my pedantic amateur entomologist self says that maggots are for flies. Termites have nymphs which sounds a whole lot more appealing anyway ;)
What was new about this discovery is that the termites stockpile crystals in their little backpacks that intensify the toxicity of the toxins they excrete from their glands when they detonate. In another article I read, it acknowledged that suicide bomber termites are old news. Using a crystal backpack to intensify the attack is what makes this significant.

Tax receipts (almost) always go up regardless of how you change tax rates because of growth in the economy and inflation. The exception being major recessions like 2008/2009.
One other thing business owners did was to leave the money in the business by investment and raises for workers. Wages and salary for workers tracked productivity very well from WW II up until the 1980s when Reagan dropped the top marginal tax rate from about 74% to under 40%. After that people started living on credit which got easier because all of those suddenly wealthier individuals had gobs of money to invest. That doesn't help the middle class much.
