A 3d rendering of a CT scan of a Rio Cauca caecilian with transparent body and bone colored skeleton, showing 7 baby caecilians inside, each rendered in a different color - counter-clockwise from tail to head - red, orange, yellow, green, light blue, dark blue, purple.

Say hello to Florida's newest established species, Typhlonectes natans - the Rio Cauca Caecilian! You can read about their relative abundance, distribution, & natural history, in our brand new paper:

Here is one individual I CT scanned that had 7 babies inside!

What can we learn about dinosaur physiology? 200 years after the 1st dino was named, new technologies yield amazing data from fossils. Physiology is vast, we hit on a few topics & gave ideas for improving hypotheses regarding how dino bodies may have worked. 🌡❤️🫁🦕🦖🧪⚒️🪶

Wooo! This will officially be my first post on this app. 🥳Linked below is a new paper lead by my colleague @stephanopteryx.bsky.social ! I am so happy to share this with everyone - see post below for more details!

Thank you!!

I couldn't have done this without such amazing collaborators!

@paleofox.bsky.social, @rockjock80.bsky.social , and Jason Bourke!

SSE, SSB, and ASN logos. Text: Tri-societies Week of Action for NSF. Science under siege: Over 1000 NSF grants have been terminated by political appointees- threatening the foundation of American innovation and education, and more cuts loom; entire research programs are being erased without explanation. What’s at stake? STEM education for K-12 students, jobs and infrastructure in rural communities, support for veterans in research and education, cybersecurity and national defense innovation, global leadership in science and technology. Join the week of action: Contact Congress: Switchboard: (202) 224-3121, tell them to protect NSF. Share your story: Post on social media #WithoutNSF #SupportNSF #SaveNSF, engage local media; use our media tool to reach out to local reporters and newspapers; engage others: communicate the importance of NSF to colleagues, friends, and family.

Join us in the evolution tri-societies Week of Action for NSF!

Call/write congress, engage with colleagues, friends and family about the importance of NSF funding!

MIT engineers turn skin cells directly into neurons for cell therapy MIT researchers devised a process to convert a skin cell directly into a neuron, eliminating the need to generate induced pluripotent stem cells. Such neurons could be used to treat spinal cord injuri...

Researchers at MIT turned a skin cell into a neuron without having to go through that pesky intermediate stem cell step. Truly incredible.

48 Scientific Societies Representing Almost 100,000 Scientists Ask Congress to Protect the Future of Science 48 scientific societies representing almost 100,000 scientists signed on to a letter asking Congress to protect the future of science

Today, a broad coalition of scientific professional societies who represent over 92,000 scientists are speaking out against the politicization and demonization of Federally funded science and government scientist jobs.

It was an honor to help the Union of Concerned Scientists with this! 🧪🌎

We're generally still figuring out the details, though. Bird lungs are very diverse and relatively understudied compared to other things.

A great list of awesome women in science! And of course, let's not forget the wonderful @jaimiagray.bsky.social herself - CT extraordinaire who created this amazing tortoise anatomical atlas! 🐢 anatomypubs.onlinelibrary.wiley.com/doi/abs/10.1...

Nice! It's a fun question to be sure. I'm in Dr. Emma Schachner's lab, and we've been CT scanning tons of birds to study their respiratory system. She's published a ton of stuff that might be helpful for you: scholar.google.com/citations?hl...

This is how you make a difference. Use your knowledge and share it with your community.
Thank you @edgarmcgregor.bsky.social for being a light in the world!

Black and white illustration depicting a scene from the Early Permian near the edge of a small lake. In the foreground is Dimetrodon eating a small Casea, while a second Casea scurries off. In the background is Edaphosaurus at the water’s edge. The flora includes calamites, pteridosperms, and sphenophyllum.

Photograph of mounted opossum skeleton with colorful 3D printed models of the middle ear bones. There is a row of anatomy and mammalogy books in the background.

A rendering of reconstructed 3D model of Haramiyavia. The teeth and a majority of the ramus are rendered in a brown material, taken directly from CT data. Much of the coronoid and anterior-most part of the jaw are rendered in transparent blue, showing the parts that were modeled.

An illustration of early mammal, Microdocodon, perched at the axis, where branches meet, on an extinct Wielandiella plant, eating a scorpionfly. In view at the upper portion of the image are two red fruit structures at the center of a whirl of leaves. The light falls on the mammal and the fruiting structure in front, and transmits light through the leaves of the branch in the background which is in shadow. Other scorpionflies fly around the scene and a leaf falls.

Hi Folks! Looks like it’s time for a reintroduction!

I started my career as a scientific illustrator and visualizations person (3D, animation, etc.) at UChicago focusing on early mammals. #sciArt 1/6
