Shape Shifted

Most new things aren't really new, they're just new to you. Other than restaurants, movies and songs, most new things are simply the latest iterations of something already created. You can even tell by the name, like Samsung Galaxy 9 or Air Jordan 11. That's not to say that the number always connotes the size of the series: there aren't 365 versions of Word nor 400 of Lexus, but you get the idea. 

That said, there are discoveries of truly new things we didn't know about before. Recently in the sky it was the water on Mars and new moons around Jupiter. On the ground it was a new species of tick, that sound waves float upwards and the finding of a new mineral never seen before on earth. There were also negative proofs: scientists announced that the marine mammal swimming off Hawaii which looks to be a cross between a melon-headed whale and a rough-toothed dolphin is indeed a dolphin hybrid, and not a cross species "wholphin." They say that's not really possible, anymore than a monke-affe, a cow-orse or a demo-publican, though sightings of the latter had been rumored before the 2016 election. Sadly, all are all just unicorns. 

But you don't have too look far to find a radical new thing that really does exist. That said, like the other examples, it's not really new, nor even unobserved. Rather it's been hiding in plain sight forever, and only now is being singled out as something unrecorded. Or more correctly, no one cared about it before, and so it is not so much "new" as un-labeled and un-described. And so as of this past week, joining the ranks of named shapes like the cube, the sphere and the dodecahedron we now have the scutoid. 

In a paper published in the journal "Nature Communications," researchers at the University of Seville describe how, as organisms develop, their organs stretch and get pulled in various directions. They bend and wrap themselves in different ways, resulting in a novel shape being created by the cells that make up the structure of those organs. The key characteristic is that the shape allows for two or more of these three dimensional forms to fit tightly together, enabling the growth of the organ. Or as described in the paper "cells in bent epithelia can undergo intercalations along the apico-basal axis. This phenomenon forces cells to have different neighbours in their basal and apical surfaces." That paints a picture, doesn't it? 

It was left to some of the researchers to try and detail it in English, and more specifically, in a language that we non-mathematicians could understand. They settled on a describing a shape that is six-sided at the top and five-sided on the bottom with one triangular side. Or as Javier Buceta, one of the collaborating researchers from Leigh University described it, "It's a prism with a zipper." Uh, thanks Javi, for that clarification. But to his credit he also added "The way those cells pack together in three dimensions is actually kind of weird." 

The researchers concentrated their work on the embryos of fruit flies, and found  the shape in structures from salivary glands to egg chambers. In short, everywhere where organs curved and twisted, well, there it was. Extrapolating to other organisms, including us, it turns out the living world is lousy with the shape, we just didn't know it was there. It's on your skin, in your nose, under your ear: you are literally teeming with the little zipper-sided suckers. 

As to the name, officially it was chosen as the shape resembles a part of the certain beetles that is called a scutellum or a scutum. Unofficially, it was called a "Escu-toid" after one of the leaders of the research group, Dr. Luis Escudero. Either way, while it's not exactly onomatopoetic, it does have a great sound. That means it's only a matter of time before it works its way into everything from fashion ("a tunic-like top with scutoid sleeves") to recipes ("cut the cucumber into small scutoids") to expressions ("he was acting like a total scutoid"). And come the 2022 Winter Olympics, the Gold Medal in freestyle snowboard will be won by the first person to nail a jump which has two and a half revolutions and three twists, otherwise known as a Backside Half Scutoid.
