This is a video of scientists pouring ten tons of liquid concrete into an ant colony, waiting several weeks for it to set, then digging it up. In doing so, they learned that the structure covers 538 square feet and travels 26 feet into the earth. To build it, the ant colony moved 40 tons of soil -- billions of ant loads of soil were brought to the surface. Each load weighed four times as much as the worker ant, and in human terms, was carried over 1/2 mile to the surface. It's amazing what evolution can construct, don't you think? [6:37]

Sure, there are entire worlds within our world that we never even give a second thought to. There's an entire subterranean Universe to explore, and you might get the feeling to do it if you listen to Mecca…
In our front yard we've got a busy nest of Pogonomyrmex rugosus seed harvesting ants. Warming weather brought them out for the first time last week, and every now and again I go out to see what they're up to. Lots of digging, it seems.
Pogonomyrmex is greek for "Bearded Ant", named 150 years ago…
As some of you might recall, I am an ant farmer. But did you know that today is the 50th anniversary of the ant farm? Fifty years ago today, Milton Levine began selling the first of more than 20 million of his Uncle Milton's Ant Farms (pictured), which is still reasonably priced at $12-20 each. As…

Most animals, at some point in their day-to-day lives, face the same problem. After they've gone out in search of food, they need to find their way home. But…
Ants! You should definitely post more about ants. Not like I'm biased, or anything.
On a related note, those massive leafcutter ant nests are big enough to be clearly visible on Google earth.
i figured that if there was one thing that would lure you back into my comments section, it would be an ant video! glad to see you again, alex.
i also have an ant story that will appear later today. it's a story with a funny title. (well, it will appear if my wifi holds up, because i am still working on it right now).
Ooh! Ooh! Don't stop there! My friend Chris use to work on ants living in acorn, when she was in Ohio. She also did some really cool stuff on slave-makers for her PhD.
For my PhD, I worked on mildew. :-(

I remember seeing an article a couple of years ago either in Scientific American or Discover magazine where a guy would pour molten nickel (IIRC) and make casts of ant nests. It was interesting to see some of the differences between the species.
Well, you've certainly found my weakness!
Scotty- the nest casting work is Walt Tschinkel's, you can see more here.
I'm torn between awe and dismay. Our ability to witness nature's mysteries still seems to be dependent on our capacity to destroy what we are studying.
I was about to ask if this came out of the Tschinkel research group (thanks, Alex!) I'll watch the video when I get home from work.
Yet another reason why the aculeate Hymenoptera rule. :-)
It is too bad that the nests have to be destroyed, but I'd suggest that Tschinkel's work has a positive impact on the perception of ants by scientists and laypersons alike that far outweighs the the damage done to the individual colonies he studies.
The first time I saw his work in Discover, I nearly passed out from sheer amazement.
Anyone have any idea by what metric they say it's "the equivalent of building the Great Wall of China"? Ant-hours compared to man-hours? Mass*distance of material transported, compared to size*number of workers?
But....man. Amazing. Some museum should build a (less extensive) human-sized version so that kids (and hell yeah, adults) can crawl around in it. Scratch that, some museum should be entirely housed in such a structure. Bonus points for it actually being underground.
