Wombats, the chubby and beloved, short-legged marsupials local to Australia. Moisture plays a role, but “it's also a factor of the primary digestive tract,” adds Bill Zeigler, senior vice president for animal programs at Brookfield Zoo in Chicago, which has had wombats since 1969. So Yang and the team expanded both wombat and pig intestines with a balloon to measure and compare their elasticities (or stretchiness).

The wombat intestines, however, had a much more irregular shape.
(CNN)A team of scientists claims to have unraveled one of the animal kingdom's more peculiar mysteries: why wombat poop is cube-shaped. Researchers, led by the Georgia Institute of Technology's Patricia Yang, said they have uncovered the digestive processes behind the mystery and. On Sunday, the secret behind this square scat was revealed at the annual meeting of the American Physical Society’s Division of Fluid Dynamics in Atlanta, Georgia. Updated 11:14 PM ET, Mon November 19, 2018. "And that is what creates the edges and the cubing.". The pig intestine had a relatively uniform elasticity, which would explain the animal’s rounder poo. "We don't know what that information they're sharing is, but it might be something about mating, it might be something about general advertising about who's in the area.". While this peculiarity has sparked much interest and debate, actual research into the intricacies of wombat scat has been scant.

But there’s something you might not know about these adorable marsupials: Wombats are the only animals in the world that produce cube-shaped poo. “I didn't really believe it,” Yang says. "We opened those intestines up like it was Christmas," said co-author David Hu, also from Georgia Tech, according to Science News. Instead, Swinbourne says the cubic shape is more likely related to the dry environments that most wombats live in. Why is wombat poo cube-shaped?

"The weird thing is that if you open up a wombat you actually find that the cubes become formed in the lower part of the intestine, before they exit the body," Carver said. "Basically around the circumference [of the intestine], there are some parts that are more stretchy and some parts that are more stiff," Carver said. To solve the puzzle, the team examined the digestive tracts of wombats that had to be euthanized following vehicle collisions in Tasmania, Australia. There is a lot we can learn from poop. The wombat, native to Australia, produces about 80 to 100 cubes of poop each night. The wombat takes about two weeks to digest its food and researchers found that as faeces move into the final 8% of the intestine, it changes from a liquid-like state into solid matter.

"The local strain varies from 20% at the cube's corners to 75% at its edges," the team said. An image of then eight-month old Derek the Wombat who was rescued from his mother's pouch after she was hit by a car in December 2015. The marsupial then stacks the cubes - the higher the better so as to communicate with and attract other wombats. The wombat's cubed faeces is a trait that's unique in the animal world, the researchers said, as cubes are usually created by cutting or molding. "It would be a cool method to apply to the manufacturing process," she suggested, "how to make a cube with soft tissue instead of just moulding it. Now we have this third method," said Patricia Yang, lead author on the study and a postdoctoral fellow in mechanical engineering at Georgia Tech, in a statement. .css-orcmk8-HeadlineContainer{display:-webkit-box;display:-webkit-flex;display:-ms-flexbox;display:flex;-webkit-box-pack:justify;-webkit-justify-content:space-between;-ms-flex-pack:justify;justify-content:space-between;}London Bridge attack: Steven Gallant up for early release after confronting knifeman.css-1dedj2h-Rank{-webkit-align-self:center;-ms-flex-item-align:center;align-self:center;color:#B80000;margin-left:3.125rem;}1, US woman faces first federal execution since 19532, France teacher attack: Suspect 'asked pupils to point Samuel Paty out'3, Coronavirus: Empty streets in France as curfew enforced4, New Zealand election: Jacinda Ardern's Labour Party scores landslide win5, Nagorno-Karabakh: Armenia and Azerbaijan accused of breaking new truce6, Coronavirus: Dutch royals return amid anger over Covid holiday7, Thailand protests: 'My father is blinded by his love for the monarchy'8, Missing Hong Kong protester Alexandra Wong 'was held in mainland China'9, Jacinda Ardern's majority may prove to be her biggest challenge10. "There is a long history of people looking to the natural world for innovations in human society," Carver said. Through this study, they have disclosed the physiological processes involved in this unique digestive trick. Serial poopers: What makes people poo in public places? The inflated balloons revealed that the tail end of the wombat digestive tract is disproportionately stretchy in some places and stiff in others. "The weird thing is that if you open up a wombat you actually find that the cubes become formed in the lower part of the intestine, before they exit the body," Carver said. "We currently have only two methods to manufacture cubes: We mould it, or we cut it.

While wombats do use their scat to mark territory, “it's not like they're trying to build little brick pyramids,” he says. By the way @BBCiPM, we’re delighted to say that we now have Wombat poo in our collection...here it is in all it’s cubic glory! It is known to deposit piles of dung outside burrows and on top of rocks and logs, most likely to communicate with other wombats, researchers believe.

Yang’s team mimicked the process by inserting balloons into the wombats’ intestines and blowing them up to observe the contours and flexibility of their digestive system.

"It would be a cool method to apply to the manufacturing process — how to make a cube with soft tissue instead of just molding it.". Yang and her colleagues plan to continue their research into this scatological superpower, and suggest that humans might even be able to learn some manufacturing tips from the extraordinary production facilities inside wombat butts. Follow Brett Molina on Twitter: @brettmolina23. "Wombats have really strong sense of smell that they use probably for communication," said University of Tasmania wildlife ecologist Scott Carver, who co-authored the study. No zoos in North America had any, so Yang had the intestines of two roadkill wombats shipped from Australia. © 2020 BBC. "In the built world, cubic structures are created by extrusion or injection molding, but there are few examples of this feat in nature," authors of the project. "We can learn from wombats and hopefully apply this novel method to our manufacturing process," said Yang. "This potentially reveals another mechanism of producing cubed-shaped objects and in that sense it could contribute to thinking about manufacturing these sorts of objects in different ways. She wasn’t sure what to expect when they arrived.

"The local strain varies from 20% at the cube's corners to 75% at its edges," the team said. "In the built world, cubic structures are created by extrusion or injection molding, but there are few examples of this feat in nature," authors of the project. To probe the intricacies of wombat poop, Yang and her colleagues examined the digestive tracts of two wombats that were euthanized after road collisions in Australia. Others just think that it has to do with the fact that in their dry habitat, wombat bodies are simply trying to extract every ounce of moisture from their food. The wombat's cubed faeces is a trait that's unique in the animal world, the researchers said, as cubes are usually created by cutting or molding.

Wombats use their cubic feces to mark territory and communicate with each other using scent, researchers said. These animals produce some of the animal kingdom's strangest-shaped scat. Finding a more concrete answer, however, hasn’t been easy. It is known to deposit piles of dung outside burrows and on top of rocks and logs, most likely to … As for why wombats poop cubes, researchers suspect the shape allows the animals to pile their feces next to their burrows and in other places to signal their territories.

"Wombats have really strong sense of smell that they use probably for communication," said University of Tasmania wildlife ecologist Scott Carver, who co-authored the study. A Georgia Tech team inflated balloons in the digestive tracts of dead wombats to learn about their uniquely cubic poops. The shy Australian marsupial is unique for being the only animal in the world to produce cubic poo. Wombats take the concept of “shitting bricks” quite literally, and are known to drop around 100 curiously cubic poops every night. Peter Clements, the president of the organisation Wombats SA in Southern Australia, concurs, speculating that it’s a combination of the two.
