🌊🐊 Were some of the earliest crocodylians venturing into the sea? 🦴 For our new paper in Palaeontology, we CT-scanned three skulls of “thoracosaurs” and found clues for a shallow-marine lifestyle in these enigmatic critters. ➡ doi.org/10.1111/pala... ️📖

It's the 9th of #ssSnaketember and it's a day for looking at #InvasiveAlienSpecies Burmese Pythons are native to India & southeast Asia. In these areas the #snakes have a #conservation status of 'vulnerable' on the IUCN Red List. [1/9] #Herpetology #SciComm #snake
A Burmese Python (Python bivittatus) coiled across the left and middle of the image. The snake is dark brown, with tan streaks and a pale underbelly. The head of the snake is lifted up, with a black forked tongue slightly protruding from its face.

“Hearing” is #ssSnaketember the 8th’s theme! Whilst #snakes do not have external "sticky out" ears, they can still hear. It is a myth that snakes are deaf, however they do have some quirks in relation to their methods of hearing. [1/6] #Herpetology #SciComm #Snake
In the style of a coloured pencil sketch: a green coiled snake bobs back and forward whilst leaning against a blue grand piano, with an open lid.

The 7th #ssSnaketember is a day for Growling! Even though many humans have never encountered a "real" #snake, thanks to film and TV, you will have probably heard a snake hiss. But did you know that some #snakes can growl too? [1/7] #Herpetology #SciComm
A king cobra snake (Ophiophagus hannah) coiled up. The snake has a light brown colour with its scales outlines in dark brown. Its head peeks over the top of a large coil. The snake rests on some fake moss on a tree trunk.

#ssSnaketember the 6th is the day for Flying! This #snake believes it can fly, believes it can touch the sky. Thinks about it every night & day, just to spread its wings and … oh wait .., This isn't flying, this is falling with style. [1/7] #Herpetology #SciComm

Finally got around to updating my website after the move to Boston. To celebrate, here's a blog post about driving a silly little car across Canada: lukejohns.online/blog/a_big_move

There and Back Again... and There Again
First off, I’d like to offer a humble apology to all of my avid readers (who?) for my prolonged absence. In my defence, a Big Life Event™ got in the way. I’ll start this update by describing the BLE and then get sidetracked by a completely unecessary story of sentimentality, daring and hubris. Enjoy! Big Life Event So what’s new? In a breathtaking display of comic timing and self-preservation, I and my fiancée both moved to the USA to start postdoctoral academic jobs… in June 2025. More specifically, I’m now a postdoctoral research fellow at the new(ish) Institute for Mechanobiology at Northeastern University in Boston, where I can keep messing around with hips for a couple of joints. Maybe I could even peek at other joints too!

The 5th of #ssSnaketember is for Egg Eaters! Can I offer you a nice egg in this trying time? Probably the best chat up line to use on a Dasypeltis #snake. This group of snakes are also known as the Egg Eating Snakes. But how does a snake eat something so round? [1/7] #Herpetology #SciComm
A tan and dark brown striped snake (Dasypeltis scabra), coiled over itself. Brown speckled eye with a slit black pupil. To the right of the snake is a shed snake skin. It is cream and has a strong honeycomb pattern.Two small cream eggs, speckled with patches of dark brown. Eggs of the Common Quail

#ssSnaketember the 3rd is about #Conservation! So how are #snakes doing? For a start, they need a new PR team! A dislike of snakes by humans can hinder research & preservation projects. Add that to the secretive nature of many snakes & conservation becomes a difficult topic. [1/6] #Herpetology

2nd of #ssSnaketember! Time for Batesian Mimicry! "It's red & black, stay back!" - is what these snakes want you to think. A Batesian mimic is another term for "a critter in disguise". These snakes have patterns that make them look like a more dangerous type of #snake [1/6] #Herpetology #SciComm

Happy 1st of #ssSnaketember! Today’s theme is Asymmetry! Take a face. The left and right side will often be mirror images. Not the case for the face of the Keeled Slug #Snake. These snakes have up to 50% more teeth on the right side of their jaw than their left But WHY? [1/5] #Herpetology #SciComm

OK so where are we on this snake-predicted stock market graph? 📉🐍 *yes, the snake was climbing the side of a tree like this!
A snake climbs the side of a tree. Its body looks like a graph showing a steep decline. Yellow axes are overlaid on the graph. The snake is better at the economy than the current administration.

Every year UTCT teaches NSF sponsored short courses on high-resolution X-ray CT, taught by UTCT staff (including me!). Applications for the 2025 courses are now open! See below for the biological/paleontological course info, & we also have a geological one. If you'd like to apply, send me a DM 🩻☢️🦴
Text that reads: The University of Texas High-Resolution X-ray CT Facility (UTCT) will host a short course on the fundamentals of acquisition, visualization, and analysis of high-resolution X-ray CT (HRXCT) data for biological and paleontological specimens June 2-4, 2025 in Austin, TX. 
This short course will present an overview of the acquisition, interpretation, 3D visualization and analysis of HRXCT data. This will be followed by hands-on training focused on 3D visualization, surface extraction, and segmentation (e.g., endocasts, digital dissection) including deep learning. Covered programs include ImageJ, Dragonfly, and 3D Slicer/SlicerMorph.    
This course is sponsored in part by NSF and funds are available to help cover the cost of travel, lodging, and meals. There is no charge to attend. Because we will not be able to accept all applicants, preference will be given to those who have/will have HRXCT data for the course and have a demonstrated need for immediate application of the skills learned. Students and early-career researchers receive priority. Participants are invited to bring their own HRXCT data, or to have specimens scanned (at a significant discount) at UTCT prior to the course.
