Andrade was so impressed that he began to wonder if the ants really “know” how to dig up the structure. The surrounding soil is then removed to reveal the final complex structure. The cut is made by pouring some kind of molten metal, plaster or cement into the ant mound, which runs through all the tunnels and eventually hardens. Co-author Jose Andrade, a mechanical engineer at Caltech, was inspired to explore tunnel ants after seeing an example Ant nest art. This final paper focuses on the western harvester ant ( Pogonomyrmex occidentalis), was chosen for its productive ability to excavate soil grains at the millimeter scale.
However, somehow, the ant can sense this small change with its body. The changes in the centrifugal and shear forces acting on the raft are very small – perhaps 2 percent to 3 percent of the normal gravitational force. This vortex can also exert additional force on the raft, enough to break it apart.

The oars moving through the river water will create a series of whirlpools (known as shedding eddies), causing the ant raft to spin. Ants recognize different fluid flow conditions and can adjust their behavior to keep the raft stable. in 2019, He and his comrades reported That fire ants can actively sense changes in the forces acting on their floating rafts. Advertisementĭavid Ho’s biological propulsion group at Georgia Tech is also studying fire ants. And only a tiny fraction of the colony digs at any one time: 30 percent of them do 70 percent of the work. like us I mentioned that time, the group concluded that when an ant finds a tunnel where another ant is already running, it retreats to find another tunnel. A Studies 2018 By Daniel Goldman’s group at Georgia Tech researching how fire ants can improve tunneling efforts without causing traffic jams. Ants also excel at regulating the flow of their own traffic. Recently, paper 2020 I found it social dynamics How the division of labor emerges in an ant colony is similar to how political polarization develops in human social networks. They concluded that these rules arose from local interactions between individual ants, without the need for central coordination.
He built a computer simulation based on these three rules and found that after a week, the virtual ants had built a structure very similar to the real anthill.
For intelligence: (1) ants pick up grain at a constant rate (about 2 grains every minute) (ii) Ants prefer to shed their seeds near other grains to form clumps and (3) ants usually choose grains marked with chemical pheromones after other ants have handled them. Ants may be small creatures with small brains, but these social insects are capable Organize themselves collectively In a highly efficient community to ensure the survival of the colony.Ī few years agoBehavioral biologist Guy Theraolase from the Institute for Advanced Studies in Toulouse, France, and several colleagues combined laboratory experiments with Argentine ants and computer modeling to Explain three simple rules Controls the behavior of ants in digging tunnels. You can pour fire ants out of a pitcher, for example, or ants can link together to build towers or floating rafts. but Pack enough Firmly united and working as a unit, they exhibit both solid and liquid properties. Some distanced ants behave as well as individual ants. This is because ants, as a group, behave like some form of granular medium. Scientists interested in collective behavior have been studying ants for decades. The team describes their work in new paper Published in Proceedings of the National Academy of Sciences. Scientists have discovered that ants have evolved to intuitively sense grain particles they can remove while keeping their structure stable, much like removing individual blocks in a game. Now, a team of scientists from the California Institute of Technology have used X-ray imaging to capture the process of how ants build their tunnels. jenga.Īnts are excellent diggers, building elaborate nests connected by an intricate network of tunnels, sometimes reaching depths of up to 25 feet. A new study from the California Institute of Technology found that ants seek out and remove loose soil particles when digging their tunnels, just as humans throw loose clumps during play.
