Expetacular!!!

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.

Hokusai Part II

David Bailey shared the link to this book full of classical Japanese artist Hokusai's sketches on tessellations. Awesome. Too awesome for one post, and together they're less than half the book!

Of course Saturn brought its ring light.

On June 25, 2023, our James Webb Space Telescope made its first near-infrared observations of Saturn. The planet itself appears extremely dark at this infrared wavelength, since methane gas absorbs almost all the sunlight falling on the atmosphere. The icy rings, however, stay relatively bright, leading to Saturn’s unusual appearance in this image.

This new image of Saturn clearly shows details within the planet’s ring system, several of the planet’s moons (Dione, Enceladus, and Tethys), and even Saturn’s atmosphere in surprising and unexpected detail.

These observations from Webb are just a hint at what this observatory will add to Saturn’s story in the coming years as the science team delves deep into the data to prepare peer-reviewed results.

Download the full-resolution image, both labeled and unlabeled, from the Space Telescope Science Institute.
