A new geometric shape was found among the cells of living things

Scientists from the University of Seville were delighted when the computer model completely matched what they saw in the structure of the cells of flies and zebrafish. This is a fundamentally new stable geometric structure called "scutoid". And if the calculations are correct, there are countless numbers of them in the human body.

Almost all cells in the body of higher beings have very different shapes. Neurons are like radiant stars, erythrocytes are disks floating in the blood, bones are like irregular, porous honeycombs. What does the epithelium look like? The most common tissue serves both as a barrier and a connecting element between other parts of the body. And it must have a very dense, load-resistant structure.

Scientists from Seville have carried out computer simulations in search of the optimal shape for "brick cells" in such a wall of epithelium. And they got it - a scutoid. A three-dimensional polyhedron, which has a flat base and apex, connected by six faces on one side and only five on the opposite. For this, the scutoid has a characteristic triangular protrusion, which makes its shape fundamentally different from the "crumpled" cylinder.

Scutoids are the best three-dimensional forms known to us to fold into dense structures. And what the computer showed on the monitor, scientists then saw through microscopes when studying real animal tissues. Most likely they are in the human body. This is a double discovery at once - in the field of mathematics and biology! And, maybe, progress in other areas, for example, if we learn to build the most durable walls in the world from scutoid bricks.
