Scutoid

The newly discovered shape that shows how nature packs cells efficiently into three-dimensional structures.

Researchers have discovered a new geometric shape that’s been hiding in plain sight.

A team studying the cells that give rise to embryos and can be found lining our organs and blood vessels pinpointed a three-dimensional shape that occurs as they bend and pack together.

The new shape, dubbed the scutoid, allows these epithelial cells to organize with the most efficiency, as opposed to the column or bottle-like shapes scientists previously attributed to this process.

Kelvin-Helmholtz clouds

are also known as “rotor clouds” and their spiraling pattern is the effect of a cloud generating a billowing wave pattern, which is a very rare occurrence. They happen when there is a severe vertical shear between two air streams, producing the upper-level winds to blow faster than the lower-level winds. Images © WSLS 10, Dave Throup, Vivian Knezevich

He links the Nature article (good and a free read).

Best one, so far:

Robert Farthauer suggests:

And, of course, the actual article, by David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss.

Kaplan gives this illustration of the tile:

He has a one page stop for info about the tiling.
