And not just human groups.Helen F. McCreery studies the process in the longhorn crazy ant, which is known for its cooperative behavior in certain tasks.
Admittedly, it does not solve geopolitical or economic problems, but groups of these ants can join to take a giant chunk of food, way too much for one ant to move, back to the nest.They do this naturally with a prize like a cricket. But for experimental work, the best bet is a bit of canned tuna. Food preferences vary among ant species and are not easily predictable. These ants, said Ms. McCreery who is a Ph.D. student in biology at the University of Colorado, Boulder, don’t tend to carry sugary items back. Although other species like fig paste, cheese, gummy bears and cat food, these ants, she said, “are kind of persnickety about what they want to carry.” They are, however, always really excited about tuna.She and her colleagues tested ants at two locations in Arizona by giving them tuna but blocking their way back to the nest with barriers made of Lego pieces.She wanted to find out what strategies they used to overcome the barriers. They mostly move in the direction of the nest, but when they are blocked, she found that they had different strategies, depending on the barrier.

For a simple wall, the ants moved along it until they were able to resume heading toward the nest.For a cul-de-sac, that strategy wouldn’t work, however. So, after a time, the ants moved in the opposite direction from the nest. She said scientists didn’t know how they communicated and agreed on a change of direction. Time spent pursuing an unproductive strategy seemed to be what prompted the change, although ants just joining the group could have had new information about the barrier. But, she said, something other than the passage of time without success influenced the group actions. When she closed off a cul-de-sac, creating a trap from which escape was impossible, the ants slowed down and quit moving much more quickly than they did in a cul-de-sac that had one opening.“
In the trap, they start slowing down right away — within a minute,” she said. In the cul-de-sac, they would work for about 10 minutes, she said.The flexibility in their approach was interesting, she and her colleagues reported in Journal of Experimental Biology, because it allowed the ants to solve a simple problem, like a wall, quickly, but also allowed a second approach to more complicated problems. How they seem to figure out when they are really trapped is still a mystery.“They really look like they’re just giving up,” Ms. McCreery said. Your new home for finding the game that suit you best.

It closely resembles the look of Batman as seen in the Lego animated movies and videogames. It's a well-built and sturdy figure - standing approx. 10" tall. It's articulated - so you can position the arms, legs and head. The cape is made from a durable fabric.The clock has an alarm function (as well as a 'snooze' option). There's also a backlight, so the time can be seen when it's dark. You can set the clock to am/pm or 24hr. It comes with batteries, and works well.I was in two minds as to whether to buy this or the Batman Lego torch (see Lego Lights DC Super Heroes Batman LED Torch and NiteLite) as they both look good.
The torch figure is slightly smaller ... eventually I settled on a Batman clock and Superman torch (Lego Lights DC Super Heroes Superman LED Torch and NiteLite) - and they complement each other well.If you're a fan of Lego Batman, I fully recommend this item. All you need to decide is whether you'd prefer a clock or a torch! Both options are great!
