LAST DAY for the Sea Star #CoralSeaFrontiers workshop-Over 211 specimens, about 60 different species, maybe 20% of those? were undescribed! (but I did just publish a new paper on New Caledonia!) my thanks to @oceancensus.bsky.social @drtimohara.bsky.social for supporting this visit and ID workshop!

3-panel comic. (1) [Three small arthropods on ocean floor.] ARTHROPOD 1: Now that we’re multicellular, what are your plans? I’m gonna evolve little legs and swim around with them! ARTHROPOD 2: I’m gonna evolve sharp pincers and use them to crunch stuff! ARTHROPOD 3: I’m gonna evolve glands to make string from my butt and use it to construct elaborate geometric nets hundreds of times my size to catch other animals. (2) [Silence] (3) ARTHROPOD 1: *Dude.* ARTHROPOD 2: Can you *please* just be normal about this? ARTHROPOD 3: *What??!*

My linocut tardigrades shows the microscopic 8 legged arthropod in a gradient of darker to more orange brown in on cream coloured washi paper with coloured confetti inclusions

Tardigrades in Space Wikipedia page.

I thought tardigrades were well known but I once sold #sciart at a microbiology conference & was surprised that there were folks there who had not heard of the mighty tardigrades, so I am happy to introduce you if new to you

Monk 1: What are you drawing? Monk 2: A poor soul being dragged to hell by demons Monk 1: Cool! And what are you planning to use as a border? Monk 2: I'm thinking freshwater mussels. Monk 1: That's really perfect

This is brilliant.

Greenland sharks grow less than 1cm per year, reach sexual maturity at 150 years old and are the slowest sharks in the world.

These deep-sea creatures live to at least 250 years, making them the longest-lived vertebrates on Earth.

DNA damage modulates sleep drive in basal cnidarians with divergent chronotypes - Nature Communications Here, the authors use the diurnal upside-down jellyfish and the crepuscular starlet sea anemone as simple nerve net models to examine the potential evolutionary origins of sleep. They describe and define sleep patterns in these species, finding that sleep deprivation increases neuronal DNA damage and that sleep facilitates genome stability.

The sleep patterns of jellyfish and sea anemones share similarities with those of humans, according to research published in Nature Communications. The findings support the hypothesis that sleep evolved across a range of species to protect against DNA damage. 🧪

When 21 men saw in the new year by dining in a dinosaur Guests braved the cold of December 1853 to have dinner inside a concrete mould of a dinosaur in a warehouse.

A fascinating historical new year's celebration involving Crystal Palace Dinosaurs.
