Merry #Crustmas! Here’s another holiday crustacean.

Dendrogaster is a genus of parasitic barnacles that live inside seastars. Females develop into a blobby body with several tree-like roots that draw nutrients from the host’s coelom.

On the anniversary of the sinking of the Titanic, we thought we'd answer a question that's often asked,

"If they raised the Mary Rose, why not raise the Titanic?"

Allow our scaled diagram to explain...
A light blue diagram depicting the sea, with the water's surface at the top, and just below it is an outline of the Mary Rose, with the depth (12m, 40ft or 6.7 fathoms). There is a line showing the seabed, which takes a rapid dive into the vertical...

Por solo 5 pesos, el #Metro de la #CDMX te ofrece baño público, encuentros casuales… y a veces hasta funciona como transporte.

Desde la pandemia de COVID-19, no ha logrado recuperar su volumen de pasajeros.

Turtles are unique in body-design. Although other animals try to replicate the "exoskeletal armor" (armadillo, pangolin), only the turtle fuses its spinal column & ribs directly to the armor (carapace).

So how did the turtle become the Iron Man of the animal world?

Let's start with "Eunotosaurus":
"Life restoration of Eunotosaurus africanus. Based on skeletal in this cladogram, originally from "Transitional fossils and the origin of turtles" by Tyler R. Lyson, Gabe S. Bever, Bhart-Anjan S. Bhullar, Walter G. Joyce, and Jacques A. Gauthier (Proceedings of the Royal Society B)." CREDIT: Smokeybjb

The ESA #Gaia mission has delivered the best Milky Way maps to date and taken its last starlight before spacecraft retirement 🔭

A model image of what our home galaxy, the Milky Way, might look like face-on: as viewed from above the disc of the galaxy, with its spiral arms and bulge in full view. In the centre of the galaxy, the bulge shines as a hazy oval, emitting a faint golden gleam. Starting at the central bulge, several glistening spiral arms coil outwards, creating a perfectly circle-shaped spiral. They give the impression of someone having sprinkled pastel purple glitter on the pitch-black background, in the shape of sparkling, curled-up snakes. A model image of what our home galaxy, the Milky Way, might look like edge-on, against a pitch-black backdrop. The Milky Way’s disc appears in the centre of the image, as a thin, dark-brown line spanning from left to right, with the hint of a wave in it. The line appears to be etched into a thin glowing layer of silver sand, that makes it look as if it was drawn with a coloured pencil on coarse paper. The bulge of the galaxy sits like a glowing, see-through pearl in the shape of a sphere in the centre of this brown line

A thread of messy professor's offices
(to make you feel better about your own)
Trigger warning for neatniks.

1. Albert Einstein.
“If a cluttered desk is a sign of a cluttered mind, of what, then, is an empty desk a sign?”
Einstein sits at his messy desk, a blackboard and bookshelves in the background. He is reading intently.

If you've heard of horseshoe crabs, it's likely you've also heard about their blue blood and its important role in biopharmaceutical quality testing. Why are we still using wild animals? Because regulatory change takes time. I dug into why it's been so slow:
