The "Skutoid" is the newest form of geometry, and it could be anywhere on your body

Scientists have just defined a new form called Scutoid (SCOO-Toid), while they examine epithelial cells, the building blocks of embryos that ultimately form our skin and lining our organs and blood vessels. They believe that the scutoid shape is extremely efficient in keeping cells tightly packed and organized in the literal twists and turns of development.

When embryos grow, their tissues curve and bend as they begin to form into organs. Scientists thought the cells might remain tightly packed if they were bottle-shaped or columnar, but computer models suggested that a more complex shape would be more likely.

First, a computer model was created to predict which cell shapes would most efficiently remain in contact, both in flat and in curved layers. This form ended prismatically, with six sides at one end, five at the other, and a strange triangular surface at one of the long edges of the prism. Look at this diagram:

Using microscopy and computer imaging, the team confirmed that cells found in zebrafish fruit fly salivary glands and cells were indeed skutoid-shaped. As mentioned in their article published in Nature Communications on Friday, the researchers believe that these scutoid-shaped cells exist in every curved leaf of epithelial cells – even in humans.

Luis Escudero, a developmental biologist at the University of Seville in Spain and co-author of the work, told Gizmodo that it was difficult to define what the new shape looked like in the early stages of computer modeling. It was not clear until one day he modeled clay with his daughter.

When the team identified the shape by name, they realized that it was completely new to math and geometry.

"It was such a surprise!" Escudero Gizmodo said.

The scutoid shape was named after this top-down view of a beetle scutellum.
Picture: Pedro Gómez-Gálvez et al. (19659003) They chose to name the scutoid after the scutellum of a beetle (part of its thorax) because both look similar from above.

Javier Buceta, Systems Biologist at Lehigh University and co-author, was grateful for the opportunity to name a new geometric shape.

"You do not usually have the opportunity in your life to name something that will hopefully be there forever," Buceta Gizmodo said. "It will not be the circle or the square, but we could name a new shape that has never been seen in nature.

It is unclear whether the shape will become obsolete after the introduction of the Triquandel.

The team also noted that the scutoid could be used in many scientific fields, including medical biology, as, for example, skutoid-shaped cells remain packed so efficiently during development that they may be well-suited for growing artificial organs. because they would provide architectural stability when a fabric bends.

"We believe this is a big breakthrough in many ways," said Escudero Gizmodo. "We are convinced that there are more implications we are trying to achieve understand as we speak. "
