New paper! How weird could Permian animals get? Turns out, pretty weird. Meet the stem tetrapod Tanyka amnicola from the Pedra de Fogo Formation of northeast Brazil

This bobtail squid burrowing into the sand is already adorable, but please watch till the very end!

It sticks out its little arms and earnestly sprinkles sand over itself 🦑𓂃◌𓈒𓐍

This fish seems to use its bizarre skull like a drum The rockhead poacher’s unusual cranial anatomy may help it communicate

Awesome article in @science.org on @danielgeldof.bsky.social Master's thesis on the secret of the rockhead poacher’s (Bothragonus swanii) unusual cranial anatomy. Daniel did some beautiful CT scans on this odd fish's head.

The cuts to research funding in Australia "represent thousands of ideas never tested, experiments never run, students never trained, and careers prematurely ended." 💯😔

Disabled students belong in biological sciences spaces! Here is a thread of some tips and suggestions to make your spaces more inclusive.

So strange to see Glenn Northcutt's an iconic comparative vertebrate brains so twisted. Very disappointing to see AI stolen art on the cover of Royal Society 😔

Investment in R&D in Australia is at a historic low. If this recent / current trend continues, within five years Australia will be among the lowest of OECD countries....

This is figure 1, which shows a three-dimensional rendering of Chamaeleo calyptratus Chamaeleonidae (UF: Herp: 191369).

A paper in Scientific Reports shows that chameleons have evolved a longer, coiled optic nerve that is likely to provide “slack” to reduce tension on the optic nerve during the extensive rotations characteristic of the chameleon eye. go.nature.com/3JTSgQ1 #evosky 🧪

Cuts to key research facilities threaten Australia’s ability to be a global scientific leader At the same time Australia has inked a deal with the US on critical minerals, it’s proposing cuts to facilities that underpin its clean energy ambitions.

ANSTO’s neutron and synchrotron facilities are among the best-run and most productive parts of Australia’s research system... It would be a grave mistake to allow short-term accounting to jeopardise long-term national capability.

What Does POTS Stand For? POSTURAL: Related to the position of your body ORTHOSTATIC: Related to standing upright TACHYCARDIA: Increased heart rate SYNDROME: A group of symptoms

It’s POTS awareness day—a blood flow problem common after Covid.

POTS can be subtle—I often wonder how many people who feel rundown, anxious or distracted have this treatable condition.

Main criteria is heart rate going up >30bpm when going from laying down to standing—smthg you can check at home!

Meet the mesmerizing new addition to our Into the Deep/En lo Profundo exhibit, rough snailfish! These ethereal charmers live in the benthic zone, a scientific term for the seafloor.

The Australian Government makes more money from HECS repayments than it does from the PRRT.

A new Jurassic fossil from Scotland, Breugnathair elgolensis, shows a combination of snake-like jaws and teeth with a lizard-like body and limbs, providing direct evidence of diverse squamate traits early in their history.

Figure from Zelaya and Marinone 2012 showing a reservoir in Bolivia, where an unfortunate water boatman was found with two pea clams clamped onto its little claws. A pea clam is shown, 4 mm long or so. A close up of a claw, and a chip on the shell from where the boatman tried to kick off its hitchhiker, and also a piece of the leg stuck in the clammed-up bivalve gill

Phoresis is the name for when one organism attaches to another for the purpose of travel, and pea clams (Sphaeriidae) are masters of it. They attach to birds, fish, salamanders, and even aquatic insects like dragonflies or water boatmen to get a ride upstream. Ride on, little clams! (293)

This common fish has an uncommon feature: forehead teeth, used for mating New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads,...

New paper is officially out!
Ratfish have a second jaw on their foreheads - CT + histology show they’re real teeth, built from the same tissues and signals as oral teeth.
