Excellent teamwork of the flock is small
can be said, is the most connected species on Earth.
In each of us, would anyone have ever caught sight tandem ants bring food to the nest. And in our subconscious, ants, though small in size but very hardworking capital, solidarity.
Recently, Professor David Hu and Nathan J. Mlot graduate student at Georgia Institute of Technology have embarked with more research about fire ants. Let's explore a few interesting things about them offline.
When cities meet flood, people fill sandbags to prevent the husband of the levees. With fire ants, they joined together to form the floating raft. It's clever feat, right?
Two researchers gave a nest egg is about to do the experiment. They poured water on the anthill to flooding, surprisingly, in less than 2 minutes the ants were "holding hands together" to form a block floating on the water surface. There is no any certain ants drowned even though it is at the top or bottom of the raft is, precisely because of the very special tiny hairs on their bodies helped them create storey air to breathe.
A herd fire ants will float on the water like the picture above. Mlot researchers said: "These ants near the top will try to leave. But when an ant has found a solid ground, usually it will turn around and return to the center position. "
By knowing the chance of survival, we immediately turn help each other at the bottom goes, upward, so turn each child seeking to survive, if not we will always just stuck together out there floating cloud.
Although people have tried to use a tree as shown above, but flooding is not being overpower. During the chaos, they tried to cling to the raft together though less well than, instead, they still have air to breathe and prevent drowning.
The researchers continue to do more experiments. They brought in a colony drop dry cereal and deliberately created a swirl, the ants will roll back like the snow ball. It easily transforms from rafts to sphere thanks to the pair of tweezers feathers as above.
Even a single ant was pushed into the water, it can float on water because the body is around the rough coat and shaggy.
Mlot added: "The only way we could keep the ants under water, that is tying a rope to it and attached to its body weight."
Soap and other cleaning agents can reduce the surface tension of water and reduce the buoyancy of an ant.
A single ant can move in the water by the surface tension of the body although it thicker than country. It is possible a raft floating a mystery.
The fact is when the herd is like 1 soft ball, whether you have compressed it or release it into the air, it will return to form as original.
The Georgia Tech research after a swarm showed that the thickness is greater than 5 times that of water, 10 times more than the surface tension of water and greater adhesion than 10 million times compared with water.
This image you are looking at under a microscope. Two ants "hand in hand" by each ant will take a foot, or a foot clamp jaw more.
Looking on is interesting picture because a teapot has been brewing since the ants baby small.
When fire ants were collected as a group, they behave like a liquid. Each ant represents a molecule, if the block is not to be friends of the random movement which will follow the rules. Here, they are free to travel as individual molecules.
