American scientists have finally solved the mystery of how Australian wombs can produce cube-shaped poo.
Scientists at the Georgian University of Technology euthanized wombats who participated in vehicle collision in Tasmania and then investigated the gastrointestinal tract.
They found that wombs are the only animals that can physically produce cube feces. The only other forms for creating this shape are either cutting or molding.
"In a built world, cubic structures are created by extrusion or injection molding, but by nature are just a few examples of this," the authors write in their research.
These night movies are about two weeks long.
Scientists revealed that the wombat waste cured its last eight percent intestinal tract.
It no longer flowed through the fluid through its body, but turned into separate cubes with a length of about two centimeters.
"My curiosity was triggered when I realized that there is a cube-like stool," says lead researcher Patricia Yang, MD, MD.
"I thought it was not true."
According to Australian Geographic, wombas can produce 80-100 cubic meters each night. This helps animals mark it in the area.
Wombati's body is capable of creating this cervix as its intestinal tract can be expanded when food is absorbed.
The researchers filled a long balloon in the wombats' intestine after it was drained and found that its walls stretched unevenly, enabling the formation of cube-shaped waste.
"The local strain varies from 20 percent to the cube at 75 percent on its edges," the team said. "This way, the intestinal tract is stretched primarily to the walls to facilitate the formation of the cube."
Scientists presented their observations at the 71st annual meeting of the American Physical Society's Fluid Dynamics Working Group in Atlanta on Sunday.
They believe that the announcement will allow engineers to find a different way to make cubes, as only two currently known methods – cutting or molding.
Wombat's intestines suggest that a third route is possible. "It would be a great way to apply the manufacturing process," Yang said.
"We can learn from Wombats and hopefully apply this new method to our manufacturing process. We can understand how to move this stuff very effectively."
