Taphonomy is the science of what happens between death and discovery.

For this #FluorescenceFriday, a gorgeous image of an adult mouse kidney labeled with AQP2 and alpha SMA antibodies. AQP2 (green) marks the collecting duct and distal connecting segment while SMA marks the arterial tree. Courtesy of talented postdoc Sarah McLarnon.

Newest paper from the lab! Led by recent lab alum Maressa Kennedy, we utilized a novel nipple apparatus capable of modulating milk flow rate and stiffness to investigate the impact of multiple sensory inputs on suck-swallow-breathing coordination in an infant pig model. 🤖🐷🍼

I'M LOSING MY MIND, THE BEST AND MOST EXCITING YHING JUST HAPPENED, BABY SNAPPING TURTLES HATCHED IN MY YARD, HOLY FUCKING SHIT WOW HOLY FUCK

I'm recruiting a PhD student to join the lab at @gtsciences.bsky.social in Fall 2026! Broad taxonomic and topical freedom under the umbrella of vertebrate joint form and function. Information here: www.manafzadeh.com – please share 🦴🩻

New paper out in Pediatric Research! We found that feeding in infant pigs raised on a ducted, biomimetic nipple more closely resembled the mechanics of breastfeeding, and that differences in nipple design impacted milk acquisition and overall feeding performance 🐷🍼

Our new paper led by recent lab alumni Hannah Shideler and postdoc Elska Kaczmarek is out in ICB @sicbjournals.bsky.social! For the first time ever, we reconstructed the volume of the oral cavity during suckling, and found that nipple design impacts tongue function.

I NEED to tell you the story of Tae Heung “William” Kim.

He's a graduate student at Texas A&M where he's working on a vaccine for Lyme disease.

He's a *legal permanent resident* of the United States.

And he's been in ICE detention for 12 days & counting, transferred Tuesday to South Texas.

Three‑row table linking scales: fish, penguin, ant. Each row shows an individual silhouette, a pair‑level interaction image, and the emergent collective - schooling fish, penguin huddle, and an ant raft.

New review in PRX Life, where we propose a tangibility scale for the physics of social interactions, and highlight a few tangible examples - from dead fish “swimming” to efficient schooling, warm penguin huddles, and dry ant rafts.
Written with the brilliant Chantal Nguyen 🐟🐧🐜

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!

One of the most irritating things about RFK Jr is how he makes things that are usually fun biologist anecdotes ("I found some neat roadkill, I got to hold a lamprey" etc) seem uncool and weird

btw did you know you can subscribe to PBS for only like $5/mo or a $60 one-time for a year donation, and get access to their Passport streaming service? They mail you a little live programming guide and everything, too. The 40-something seasons of NOVA alone are worth it.

The Mayerl Lab at NAU is looking to recruit a PhD student for Fall 2026! We take an integrative approach that bridges engineering, clinical, and evolutionary approaches to study feeding physiology of vertebrates. Our lab website is linked in our bio, and feel free to reach out on here or via email.

Are you a PI in a biology field looking for students to join your lab as a PhD student? I made a Starter Pack to help PIs and potential PhD students connect! If you would like to be added to this pack, please let me know! go.bsky.app/EFj87fi

Being true to yourself amidst a changing world [for over 150 million years]

Maybe that's the real punk rock👍

One of my favorite moments I’ve ever captured back from my master’s work on Basiliscus plumifrons water-running mechanics. Each splash you see is approximately equivalent to one stride length. I like to think of these as almost “footprints” at the water’s surface.

I love learning about the sensory systems and mechanics of these amazing animals!

Our paper reviewing the neurophysiology of swallowing just came out! We detail 70 years of progress towards understanding neuromotor functioning in feeding, and highlight several emerging technologies for the future

An aquatic armadillo paddling through water. Source unknown.

The 9 banded armadillo, the state mammal of Texas, is heavy-bodied but has two methods of crossing water.

1. They can hold their breath for 5-6 minutes at a time, and walk along the bottom.
2. They can gulp air to increase buoyancy and swim (dog paddle) for up to an hour.
