A little animal, a native of Australia, is the main character of the great scientific mystery. How can viruses called wombats or vombatids be able to eat cubes? This is the only known species that produces stools
with these sizes, and does so in significant quantities.
The uterus can devastate overnight about 100 cubes that he bought in mounds to mark the territory. Although these animals have round-years as other mammals, they do not produce stools in balls or in soft piles.
A group of scientists in the United States says that the cause of strange cubes in the uterus is in
specific features of the intestine.
"The first thing that made me study this is that I have never seen anything so odd in biology, it was a mystery," says Patricia Young, a postdoctoral science mechanic at the Georgia Institute of Technology in the United States.
Yang and his colleagues studied the digestive tracts of the uterus slaughtered after a collision with vehicles in Tasmania. "We began enthusiastically to dissect the intestines of animals as if it were a Christmas present," said David Hu, another researcher before the BBC.
Scientists compare the gut of the warts with those of the pigs and insert expanding balloons into the digestive tract of the animals to measure their elasticity.
In the case of the uterus, stools change from a liquid state to a solid state in the last 25% of the intestine. And in the last 8% of the intestinal tract, scientists have found a great change in elasticity.
This is the variable elasticity of the intestinal walls, which explains the formation of stool cubes about two centimeters on each side.
The cubes allow the uterus to collect its chairs effectively not only to mark the territory, but also to communicate and attract other warriors.
"We currently have only two methods of making cubes, molding or cutting, we now show a third way," Yang said.
The study could help in the future to "apply a method similar to wombats in manufacturing processes to produce cubes with soft substances instead of molding them."
Young and his colleagues presented their findings at the annual meeting of the Physical Dynamics Division of the American Physical Society, which took place this week in Atlanta.
