• Researchers have solved the mystery of how bare-nosed wombats, native to southeastern Australia, produce poop in cubes, reports the International Business Times.
Wildlife ecologist Scott Carver of the University of Tasmania is lead author on a study, published Jan. 28 in the journal Soft Matter, that details the particular inner workings of the wombat's digestive tract that produce the square-shaped dung.
"This ability ... is unique in the animal kingdom," Carver said.
"Our research found that ... you really can fit a square peg through a round hole." [International Business Times, 1/29/2021]
