Researchers investigate microstructure evolution of oxide films of Fe-Cr–based alloys

Ferritic/martensitic steels and austenitic steels are the primary candidate materials for advanced nuclear energy systems. The corrosion resistance of the materials is one of the factors that ensures the safe service of key components. Since the corrosion resistance of materials is highly related to the characteristics of the formed oxide films, it is crucial to investigate the oxide films of candidate materials in high-temperature water. Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) selected candidate materials (15-15Ti, 316L and T91) to study their early oxidation behavior in high-temperature steam and the evolution process of the oxide microstructure. The results were published in Journal of Materials Science & Technology. The Ni-rich layer in the oxide film of austenitic steels (15-15Ti, 316L) is composed of Fe-Cr spinel oxide and Ni-rich phase. Researchers at IMP found a large number of nanopores in the inner oxide layer that could serve as a rapid gas transport channel for oxidant. They revealed the evolution process of Ni-rich layer and the formation mechanism of nanopores in the inner oxide layer.

Microstructure Insights: Ti6Al4V ELI – Why Continuous Alpha Networks Matter

In industries like medical and aerospace, material performance is critical. The microstructure of Ti6Al4V ELI plays a crucial role in ensuring safety and durability. But have you ever wondered why continuous alpha networks can pose a significant issue? Here's why:

➡️ They create brittle points, increasing the risk of failure. ➡️ They reduce toughness and fatigue resistance. ➡️ They provide pathways for fatigue cracking, compromising durability.

Why is it important to examine the microstructure at higher resolutions?

Ti6Al4V ELI has a very fine microstructure in the annealed condition, making it difficult to assess the alpha network and phase distribution at lower magnifications (100x-500x). To accurately determine if a continuous alpha network has formed and to analyze the distribution of alpha and beta phases, it's essential to use magnifications of at least 1000x or higher.

"A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of "petals.""

"Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible."

"The microflowers can be produced in various geometries, not only with different inner and outer radii, but also with variable numbers and widths of petals. This flower-shaped geometry causes the field lines of an external magnetic field to concentrate in the center of the device, resulting in a greatly intensified magnetic field.

The study is published in the journal ACS Nano."

Microscopy: Foam, Red and White

We all love foam. It’s soft, fun to play with, and keeps our delicate belongings safe. Turns out, the structure of foam is miraculous once viewed under a microscope. This makes sense: foam is a fibrous matrix of interconnected tissues that is bound to be intricate and captivating at the microscopic level (and isn’t something I discovered completely by accident because I was out of crystals and was trying everything I could get my hands on).

So, ladies and gentlemen, foam, red and white.

So fragile-looking, so thin, so delicate. As if they’d crumple under the slightest touch. Which is true, they do. But together, with each of the fibers holding the other up, they are surprisingly resilient and possess a (relatively) high tensile strength.

A greater magnification. Hazy, as if the background is sheathed in fog. The microscopic ends stick out like the sharp blades of snowflakes. And the white, unfocused void, well, that is something I’m not ready to tackle yet.

A little closer up. See how some fibers reach out and interconnect into pentagons or hexagons. Notice how others only reach into minuscule oblivion, their ends sticking out. Yearning, perhaps, for a connection, or for an old junction long ripped apart.

I love repeating structures. The walls are almost hexagonal. The fibers light, thin, and interconnected. Almost representing bubbles or froth. Maybe a hive, or a zoomed-out, black-and-white image of a brain, the neural circuits and synapses a chaotic jumble, yet at the same time possessing a natural symmetry. Notice also the blurred structures in the background. This same image repeated layer after layer throughout the entirety of the foam, but the microscope could only focus on one layer at a time.

This is from a piece of red, packaging foam, pretty tough to the touch. My first thought was red onion cells, but it feels more akin to human tissue. Red-tinted. Thin and flimsy to the point of transparency. Delicate, yet possessing a sort of wafery complexity.

Wonderful, vivid, elegant, and red. Look at the tiny, fluttering lines, the fibers, the curvatures, and the overlapping layers. Look at the delicacy, the vibrancy of the color, and how the light filters through the bottom. Zoom in to see the tiny inconsistencies between the cells, bits of dust, probably, but who knows what exactly is trapped between those folds?

A bit more mauve–if I’m using the word correctly. Richer, darker, and more elegant, but with the same flutter and flimsy as the last. Notice the minute imperfections between the cells, the dirt, and the debris. Notice also the blurred out portions at the top. They were part of a layer above that I focused out of view.

Pairing: Oscar Piastri x Felicity Leong-Piastri (Original Character)

Summary:  Andrea Stella figures out that Felicity Piastri is more than “just” Oscar’s wife. 

Notes: Big thanks to @llirawolf , who listens to me ramble and checks my science-y mumbo jumbo 😂

(divider thanks to @saradika-graphics )

It started the way most breakthroughs did—not with a groundbreaking discovery, but with a tired engineer holding a half-wrinkled printout and a hopeful expression.

“Boss,” James said, hovering just inside the doorway of Andrea’s office. “I think you should read this.”

Andrea looked up from his laptop. “If it’s another CFD model from that Reddit forum, I swear—”

“It’s not. It’s from a paper. Academic. Legit. Published in Race Systems & Applied Motion last month.”

Andrea raised an eyebrow. “Obscure.”

“Very. It has like 20 readers,” the engineer agreed. “But I think it’s real. It’s clean. It’s sharp. It’s…” He hesitated. “We might want to test it.”

That got Andrea’s attention.

He took the paper and began to skim.

Title: Redefining Compliance: Adaptive Suspension Geometry Under Load-Sensitive Parameters for Mid-Field Chassis Configurations.

Andrea kept reading. It was dense—academic, yes—but it was also practical. It spoke the language of someone who knew exactly what they were doing. There were no ego traps. No unnecessary complexity. Just hard math and hard-earned insight.

Andrea flipped the page. Then another. His eyes caught a note referencing flex dynamics in chassis response curves and passive recovery lag.

It was correct. More than correct. It was insightful.

The author wasn’t spitballing ideas from afar—this was the work of someone who had lived in the theory and understood the application. Who referenced real-world tolerances. Racing examples. The math was sound. The diagrams were better than half the ones their CFD team managed.

Andrea flipped back to the byline.

Dr. F. Piastri.

Piastri. 

James grinned. “Fun coincidence in the name, right? He’s smart.”

Andrea didn’t correct him.

Because yes—coincidence. Probably. But something about it stuck in his brain, like a whisper he couldn’t quite place.

He read the essay in full that night—twice. It was elegant, sharp, and frustratingly precise in the way only truly experienced voices ever were. The type of clarity that came from years of not just understanding a concept, but translating it into reality.

The next morning, Andrea sent out an internal email.

Subject: Additional Works by Dr. F. Piastri If anyone has access to prior publications by this author, please forward them to me.

By the end of the week, his inbox was full.

One essay became three. Three became eleven. Eleven became twenty. 

Each one published under the name F.Piastri, buried in obscure journals and small-circulation engineering reviews that didn’t get traffic unless someone was either deeply curious or incredibly desperate. 

Andrea was both.

Each article was smarter than the last—strange, elegant engineering thought-pieces published across the most obscure academic mechanical journals Andrea had ever encountered. Niche ones. The kind that only the most obsessive minds contributed to, with names like Thermoelasticity in Microstructured Materials and Lateral Load Adaptation Quarterly.

F.Piastri had written:

An article about Load-dependent understeer in transitional corners (with math that Andrea double-checked twice because it was too clean).

A 2019 think-piece on long-run stability under thermal degradation.

An essay about Aerodynamic oscillation buffering for short-track endurance vehicles.

An article about the economic viability of 3D printed carbon struts under rotational shear (he actually flagged that one for McLaren Applied).

 A thesis that corrected a widely accepted torque model—buried in a conference archive.

A published rebuttal in Journal of Vehicle Design so politely worded it read like a love letter—until you realized she’d rewritten the reviewer’s assumptions line by line.

There was even one article on fluid dynamics that had been cited in a grad-level textbook from ETH Zurich. 

Andrea devoured them all.

He—She?—wrote like someone who saw the car before it was built. Who understood not just how suspension worked, but how it felt. How energy passed through a chassis not as force but as intent.

The writing style was sharp. Practical. Absolutely ruthless in its logic. There was clarity there—an elegance—that reminded him of only a few people he’d ever worked with.

It was revolutionary. It was poetic.

By the time he tracked down the doctoral thesis from Oxford, Andrea wasn’t breathing properly.

Reinforcement Through Flexibility: Dynamic Adaptation in Composite- Structured Performance Environments.

By: F. Piastri.

 Submitted: December 2022

Andrea stared at the name.

F. Piastri.

He stared for so long his tea went cold beside him.

His hands were shaking—not because of nerves, but because he already knew.

He opened the PDF. Skimmed past the table of contents. Scrolled through diagrams that made his heart stutter.

There was no photo. No biographical section. Just a clean Oxford University seal, 284 pages of dense, brilliant theory, and then—

A dedication.

To Oscar: For believing in a future that didn’t exist yet, and building it with me anyway. Every lap, every choice, every time—you’ve been my constant.

And to Bee: For reminding me that softness and strength aren’t opposites. You are the best thing I’ve ever helped create.

Andrea sat back in his chair like he’d been physically shoved.

Bee.

Oscar. 

F. Piastri. 

Felicity Piastri. 

Felicity.

Oscar’s wife.

Dr. F. Piastri wasn’t some reclusive academic or distant uncle with a gift for simulation modeling.

She lived in Oscar’s house.

 She packed his lunchbox.

 She raised their daughter.

 And she had published papers on suspension theory that half of F1 would kill to understand. Quietly. Efficiently. Correctly.

Andrea leaned back in his chair, stared at the ceiling for a long moment, and whispered:

“…Of course it’s his wife.”

Of course the quiet, composed driver who rarely raised his voice and always had one hand on the bigger picture had married someone brilliant. Of course she wasn’t just talented—she was a published expert with a doctorate from Oxford.

Not a coincidence. 

Not a mystery engineer.

Not some guy.

But Oscar’s wife.

Oscar Piastri—quiet, methodical Oscar—had married a genius.

A doctor of mechanical engineering from Oxford who wrote better technical documentation in a margin note than most engineers did in a year. Who published under initials. Who could probably solve half their handling inconsistencies while holding a toddler on her hip.

Andrea sat in silence for a full minute.

Then he exhaled. “...of course he did.”

He opened a new tab.

Email draft: 

To: Technical Team 

Subject: URGENT – Reference Reading Required Attached: Every single thing Dr. F. Piastri had ever published.

***

The meeting was meant to be quick.

Just a routine Monday touchpoint—debrief, run through media notes with Sophie, talk sponsor appearances, maybe discuss Oscar’s upcoming comms obligations.

Zak had rolled in with a protein shake.

Lando was lounging sideways in a chair like he’d melted into it.

Oscar had a protein bar and an expression of polite mildness, as usual.

Andrea, meanwhile, had not slept.

 Not because of the race.

 Because he’d spent the entire weekend reading Dr. Felicity Piastri’s entire body of work. Every published paper. Every obscenely niche journal article.

And her doctoral thesis.

He hadn’t meant to do it all in one sitting. He just couldn’t stop.

By 2 a.m. he was muttering things like “Of course she used Euler-Bernoulli assumptions, she’s too smart for non-parametric bullshit.”

 By 4 a.m., he’d highlighted her proposed solution to dampen micro-vibration load in corner exits.

 By 6 a.m., he had a headache, an existential crisis, and a desperate need to know: Why had Oscar Piastri never mentioned this?!

So at the end of the meeting—just as Sophie was wrapping up and Lando was aimlessly spinning a pen like a propeller—Andrea set down a file on the table.

Calmly. Casually. Like he hadn’t just had his entire mechanical worldview rattled by a woman who wasn’t even on the payroll.

“Oscar,” Andrea said, voice deceptively neutral. “Why didn’t you ever mention that your wife holds a doctorate in mechanical engineering?”

Oscar, halfway through eating his protein bar, blinked. “What?”

Andrea gestured vaguely, as if the thesis were still radiating brilliance from his desk. “Felicity. Doctorate. Thesis. Dozens of published papers. Half of them useful to our current car design issues. Why didn’t you say anything?”

Oscar blinked once. “Oh. Yeah. She gets bored sometimes.”

Andrea blinked back.

Lando stared like he’d been smacked with a front wing. “Wait—she got a doctorate?!”

Oscar nodded, chewing. “Yeah. Finished it in 2022. She was stuck in that horrible flat in Enstone while I was back and forth with Alpine, and she got bored. Wrote most of it at the kitchen table while Bee napped.”

Andrea just… stared. 

He had read the thesis. Studied it. The mathematical modeling alone had kept him awake at night—and she had apparently written it during toddler nap times, while stuck in a damp shoebox flat in Oxfordshire.

Zak looked up slowly from his tablet. “Your wife was bored. So she got a PhD in mechanical engineering.”

Oscar shrugged. “She already had the research mostly done before Bee was even born in 2020. She just had to write it up. Bee was napping a lot anyway.”

Sophie blinked. “She wrote a 200-page dissertation with a toddler in the house?”

Oscar just shrugged. “It helped that Bee liked the sound of the keyboard.”

Andrea turned to Zak, still stunned. “She predicted the kind of high-frequency oscillation we’re seeing this season. Two years ago. In a footnote.”

Lando leaned forward like he was watching a live feed of someone discovering aliens. “She’s just, like, a genius?” he asked, voice too loud, too incredulous. “And you never brought it up?”

Oscar just sighed. “She hates that word.”

Andrea just stared at him. “Oscar, she’s not just good. She’s formidable. Has she ever applied anywhere formally?”

Oscar looked genuinely confused. “Why would she apply anywhere?”

Andrea stared. ��To work. In engineering. In motorsport. Academia.”

Oscar blinked. “She does work. She manages our lives, Bee, the house, and the chickens.”

Lando leaned toward Andrea, wide-eyed: “I’ve never felt dumber in my entire life.”

Andrea sighed. “Join the club.”

***

The kitchen smelled like vanilla and wood polish and faintly like chicken coop — which meant Felicity had mopped and baked and wrangled Mansell, the escape artist hen, all while probably rebalancing one of their stock portfolios.

Oscar dropped his bag by the door and leaned against the kitchen entryway.

Felicity was sitting at the table in her old university hoodie, feet bare, Bee curled up under her arm asleep with Button the frog as a pillow. There were spreadsheets open on one side of her laptop screen, a half-watched nature documentary on the other, and one of Bee’s plastic toy bulls standing solemnly in the middle of the table for reasons unknown.

He smiled.

God, he loved her.

“Hey,” he said softly.

Felicity glanced up. “Hey. Dinner’s in the oven. Bee passed out mid-pie crust.”

“Excellent,” Oscar said, dropping into the chair beside her. “Because I need carbs.”

She raised an eyebrow, equal parts amusement and curiosity. “Bad day?”

“No. Just... intellectually humbling.”

Felicity made a low amused noise and went back to her laptop. “Did Lando try to explain crypto again?”

Oscar snorted and reached over to carefully lift Bee into his lap, her curls warm against his hoodie. She barely stirred.

He could have let it sit. Saved it for later. But it was buzzing under his skin.

“Stella read your papers.”

That got her attention.

Felicity paused, her fingers stilled mid-scroll. “Which one?”

“All of them,” Oscar said. “Apparently it started with one of the engineers, who brought an article in from Race Systems & Applied Motion. Then he spiraled.”

“Ah,” Felicity murmured, unsurprised. “That one had a good diagram.”

“He found your thesis,” Oscar added.

This time she didn’t answer right away.

He reached for one of Bee’s crayons and twirled it idly in his fingers, watching her.

“He read the dedication,” he said, voice quieter now.

Felicity’s eyes softened in that way that always undid him a little. Always had.

“Did he say anything?” she asked.

Oscar smiled faintly. “He said you’re formidable.”

There was a beat of silence.

Then Felicity laughed—not loud, not startled, just warm and wry and a little disbelieving.

“God help the man,” she said. “He must have hit the rebuttal piece from the Vehicle Design Journal. That one made a few engineers cry.”

Oscar grinned. “Yeah, well. He was halfway to building you a shrine by the end of the meeting. I also told him you got bored in Enstone and wrote your PhD while Bee was napping.”

Felicity gave him a look. “You make it sound like I was scrapbooking.”

“Weren’t you also doing that at the time?”

Felicity blinked. “...Okay, fair.”

Bee stirred slightly in his lap, a tiny sigh escaping her lips as she nuzzled deeper into his hoodie sleeve.

Oscar looked down at her—this tiny human they somehow made and raised—and then back at the woman across the table. 

Her hair was messier than usual, strands escaping her braid, and there was a faint flour smudge near her temple. She hadn’t bought herself a new pair of jeans in two years. She sometimes forgot to eat when she was buried in simulations. She once fixed the bathroom plumbing at midnight because she didn’t like how the guy from the hardware store spoke to her.

She was the smartest person he knew.

Oscar knew most people wouldn’t think it when they first met her. She smiled too easily. She didn’t correct anyone. She let others assume things—that she was just the girlfriend, just the wife, just the mother.

But she had a doctorate from Oxford, and more published academic papers than most career professors. She could hold court with race engineers and theoretical physicists in the same breath, then go home and teach Bee how to build a pulley system out of Lego and twine. She spoke in quiet, exact terms, and when she challenged people, she did it so gently they sometimes didn’t notice until it was too late.

He’d long since stopped being surprised by her. He’d just—normalized it. Integrated it. Felicity being a genius was like oxygen to him: invisible, essential, and easy to take for granted until someone else nearly passed out from the realization.

She was just Fliss to him. 

The woman who sold her designer bags to pay rent when her family cut her off. The mother of his child. His fiercest critic and his most devoted supporter. The one person he trusted without hesitation.

She didn’t want headlines or praise. She wanted quiet mornings and clever puzzles. She wanted Bee to grow up confident. She wanted Oscar to remember to eat something green.

She was the smartest person he knew — and she hated being called smart. So he didn’t. He just came home.

“He called you formidable,” he repeated. “And I agree. For what it’s worth.”

Felicity smiled then—slow and quiet, the kind that reached all the way to her eyes.

She leaned across the table and kissed his temple. “Thanks,” she said. “But if he asks me to consult, I’m charging him triple.”

Oscar laughed softly and ran a hand through Bee’s curls. “Deal.”

And he meant it. Because maybe it was easy for him to forget sometimes, tucked into the quiet rhythm of their life, that the world hadn’t caught up to how brilliant she was.

But he never stopped being proud of her.

Not for a second.

Talking about medical reality isn't ableism

One of the most striking findings was that post-COVID deficits in hospitalized patients look similar to 20 years of normal aging. The team also found that people who had been hospitalized with COVID had reduced brain volume in key areas and abnormally high levels of brain injury proteins in their blood.

Our findings indicate that COVID-19 is associated with molecular signatures of brain aging and emphasize the value of neurological follow-up in recovered individuals.

The pandemic has highlighted the complex interplay between viral infection, immune aging, and brain health, that can potentially accelerate neuroimmune aging and contribute to the persistence of long COVID conditions. By inducing chronic inflammation, immunosenescence, and neuroinflammation, COVID-19 may exacerbate the processes of neuroimmune aging, leading to increased risks of cognitive decline, neurodegenerative diseases, and impaired immune function. Key factors include chronic immune dysregulation, oxidative stress, neuroinflammation, and the disruption of cellular processes. These overlapping mechanisms between aging and COVID-19 illustrate how the virus can induce and accelerate aging-related processes, leading to an increased risk of neurodegenerative diseases and other age-related conditions.

"COVID-19-induced microhemorrhagic lesions may exacerbate DNA damage in affected brain cells, resulting in neuronal senescence and activation of cell death mechanisms, which ultimately impact brain microstructure-vasculature," says Dr. Muralidhar L. Hegde, Ph.D., a professor of neurosurgery at Houston Methodist and a corresponding author of the review. "These pathological phenomena resemble hallmarks of neurodegenerative conditions like Alzheimer's and Parkinson's diseases and are likely to aggravate advanced-stage dementia, as well as cognitive and motor deficits."

Covid results in brain damage. Brain damage results in shifts in behavior and/or personality. This is something that must be discussed.

The constant ebb and flow of hormones that guide the menstrual cycle don't just affect reproductive anatomy. They also reshape the brain, and a new study has given us insight into how this happens. Led by neuroscientists Elizabeth Rizor and Viktoriya Babenko of the University of California Santa Barbara, a team of researchers tracked 30 women who menstruate over their cycles, documenting in detail the structural changes that take place in the brain as hormonal profiles fluctuate. The results, which are yet to be peer-reviewed but can be found on preprint server bioRxiv, suggest that structural changes in the brain during menstruation may not be limited to those regions associated with the menstrual cycle. "These results are the first to report simultaneous brain-wide changes in human white matter microstructure and cortical thickness coinciding with menstrual cycle-driven hormone rhythms," the researchers write.

A beautiful blue butterfly wing offers a new way to study cancer

Shining polarized light through it and onto tissue can reveal how advanced the disease is

The morpho butterfly is a flying marvel. It flits through the rainforests of Central and South America. With wings that can span 20 centimeters (8 inches), it can be bigger than most human hands. Those wings shimmer with a dazzling blue hue. New data show these butterfly wings could one day become the basis of a new medical tool — one that might help doctors investigate the development and severity of some cancers. Although this butterfly’s wings are blue, that hue is not due to any pigment. Instead, it comes from how light reflects and refracts off tiny microstructures atop those wings. The shimmering color of the wing depends on how light hits it. (Many materials, from rocks to plastic wrap, have this property, called structural color.)

The properties of metals are determined by their metallurgy, and for applications such as medical use, these properties must be optimized. To achieve this, international standards specify the required microstructure. Two key standards for medical titanium materials are ASTM F136 and ISO 5832-3.

ISO 5832-3 defines microstructure classes with specific alpha and beta morphologies and phase distributions, detailed through micrographs. In contrast, ASTM F136 outlines microstructure requirements without specifying exact classes or providing micrographs, thus omitting precise details on alpha and beta phase distributions.

To illustrate this, consider the example of the color blue. ASTM F136 broadly accepts any shade of blue for medical applications. However, ISO 5832-3 specifies exact color codes, categorizing shades from Class Sr. No. A1 to A9, and thus sets rigorous microstructure requirements for medical grades. ASTM F136 lacks this level of detail and does not categorize shades of blue, merely stating that any blue is acceptable for medical use.

Therefore, adhering to the ISO 5832-3 standard is crucial for ensuring the precise microstructure requirements in Titanium materials needed for medical device manufacturing.

Croc Paleontology Recap Febuary 2025

January passed so fast probably cause its the shortest month but we still got a handfull of papers out of it. So lets get right into it.

The function of the armor of Stagonolepis

Getting us started in the Triassic is a paper on the osteoderms of the aetosaur Stagonolepis: "The histology and function of the dermal armour of the aetosaur Stagonolepis olenkae Sulej, 2010 (Archosauria, Pseudosuchia) from Krasiejów (SW Poland)". Now as you probably figured from the handfull of times I've talked about aetosaurs on here, their osteoderm armor is very characteristic, very important in telling them apart and VERY extensive.

The results of this study are interesting. For starters, although osteoderms frequently serve a function in thermoregulation in modern crocs and even temnospondyls, this does not appear to have been the case for Stagonolepis. Now superficially, aetosaur osteoderms do show the same pitted surface as modern croc armor, which is caused by the elements absorbing bone and depositing it elsewhere throughout growth, something that reduces mass while maintaining stability and also increases surface area. However, Stagonolepis osteoderms are not vascularized like those of modern crocs, lacking the densely packed blood vessels that help absorb heat. The external surface of the osteoderms also doesn't show signs of thick sharpeys fibres, which are generally used to anchor the osteoderm in the soft tissue. What this means is that the osteoderms were not deeply embedded in skin (as has been suggested for some notosuchians) but rather were covered in keratin like those of modern crocs. But if not for thermoregulation, then what are the osteoderms for. Well on the one hand, obviously they work as armor. Their structure makes them robust yet leight weight and they are firmly embedded through sharpeys fibres present on the lower cortex of the osteoderms (tho its highlighted that they aren't as densely packed as in ankylosaurs). The keels that mark the osteoderms further prove to be quite usefull when it comes to reducing stress from a vertical attack. If you really want an additional reason for the armor, the authors offer the suggestion of being an adaptation to prevent water loss. Finally, histology shows that the osteoderms do not feature lines of arrested growth (basically signs for poor growth throughout the animals life), which suggests that the environment inhabited by Stagonolepis was quite moderate and did not have strong seasons that might influence the animals growth throughout its life.

Growth strategy in Trialestes and its implications

Up next something not too different from a study we had in January. Last time we had a study on the growth of a peirosaurid notosuchian, this time "A fast start: Evidence of rapid growth in Trialestes romeri, an early Crocodylomorpha from the Upper Triassic continental beds of Argentina based on osteohistological analyses" brings us something similar except for the "sphenosuchian" Trialestes (more on that group later).

So what did we learn? Well for starters, neither of the examined specimens (which included the holotype) were mature, both in terms of sexual maturity and skeletal growth. What is weird is that morphology (specifically bone fusion in the vertebra) indicates the opposite to what has been concluded based on bone microstructure, which may suggest that in Trialestes either reached sexual maturity at a delayed rate of that histology and sexual maturity do not correlate all that much. Anyhow, based on crosssections of the bones, they are estimated at a minimum of two years and one year of age at the time of their deaths. Histology also shows that Trialestes appears to have grown quite rapidly. Curiously a previous study estimated a third specimen to have been one year old, eventhough this new study recovered the same age for a specimen only half that size. This seems to suggest that age and growth do not really correlate for some unknown reason, with possible explanations including differences between sexes or simply differing environmental conditions. Looking at the results at a grander scale, similar growth rates have previously been calculated for other nimble crocodylomorphs such as Terrestrisuchus and Saltoposchus, with the latter growing even faster than Trialestes. Of course when you get into more derived members of Crocodylomorpha strategies start to change, for example the slightly more derived Hesperosuchus was growing at a slower speed than Trialestes and if you recall January we know that Notosuchians can differ even within a genus (see Araripesuchus). Modern crocs appear to generally grow slower overall in their ontogeny, tho in some like the broad-snouted caiman environmental conditions seem to play quite the rolle. Nevertheless, the paper concludes that faster growth rates appear to be more widespread in early crocodylomorphs and may have been the ancestral condition.

Now for two papers that are very relevant to my efforts on Wikipedia, namely two studies on the European alligatoroid Diplocynodon.

Growth strategy of Diplocynodon hantoniensis

First of all, sorta the same thing we just had for Trialestes but applied to Diplocynodon hantoniensis, a species from the Eocene of southern Britain (and actually one of the first Diplocynodon species discovered). The greater goal of "Evolution of growth strategy in alligators and caimans informed by osteohistology of the late Eocene early-diverging alligatoroid crocodylian Diplocynodon hantoniensis", as you might guess from the title, is actually to use Diplocynodon in order to figure out how growth strategies evolved in the two modern groups of alligatoroids, gators and caimans, who share similar strategies despite having been separated from another since before the extinction of the dinosaurs.

With 9 studied upper leg bones, the sample used in the study ranged from immature specimens to adults, which in the case of D. hantoniensis might reach lenghts of 1.2–3.4 meters. The growth strategy of Diplocynodon is recovered as both being determinate (meaning that they stop growing at a certain point) and seasonally controlled (which feels self-explanatory), both also seen in modern alligatoroids. Now assuming that the growth marks accurately reflect yearly intervals (which may not necessarily be the case), then the studied individuals ranged between 5 and 26 years old at the least. Skeletal maturity seems to have been reached in a similar range as modern alligatoroids (gators reaching maximum size between 30 and 40 and caimans between 12 and 18). As with Trialestes earlier, there are some individuals that show signs of being fully grown, yet are less than half the size of other individuals, possibly indicating sexual dimorphism (female gators stop growing earlier and at a lower size than males) or environmental conditions that affected growth (though there is doubt cast over this latter interpretation). The study concludes that, based on Diplocynodon hantoniensis, alligatoroids are simply relatively conservative in their growth strategy and what we see in gators and caimans is likely their ancestral strategy, rather than having been developed independently.

Below: A photo of the skull of Diplocynodon hantoniensis (taken by John Cummings), not actually relevant to the study but I mean it shows what this thing looked like.

The sense of smell and EQ of Diplocynodon tormis

Moving away from the Eocene of the UK and to the Eocene of Spain, we got a different species of Diplocynodon as the main subject of "New data on the inner skull cavities of  Diplocynodon tormis  (Crocodylia, Diplocynodontinae) from the Duero Basin (Iberian Peninsula, Spain)". Specifically, the study deals with the description of and what we can learn from a CT-scan that gives us insights into the forebrain, olfactory bulbs, nasal cavity, air sinuses, etc..

Overall the shape of the brain matches the idea that Diplocynodon is an early alligatoroid, including some distinctive features of this clade and some traits that are basal to crocodilians. Like modern alligators, Diplocynodon tormis seems to have had a good sense of smell, though not as keen as that of crocodyloids. The holotype specimen falls within the upper values in terms of olfactory acuity among alligatoroids, but still clearly outside of the range exhibited by crocodyloids, while another studied specimen performed a lot poorer (though its also not as well preserved). As for cognitive abilities, the study also calcuated the Reptilian EQ of D. tormis. The authors note that the EQ of Diplocynodon tormis appears below the average of other medium-sized crocodilians and instead comes closer to the EQ of large forms. Tho it is also noted that damage to the specimen might have affected the results.

A history, redescription and the biology of the teleosaur Macrospondylus

Ah Macrospondylus bollensis, once known under the name Steneosaurus (like every other teleosauroid lets be honest), perhaps one of the most well known members of this group given its extensive fossil record from the Posidonia Shale in Germany. Despite this, and also like many other teleosauroids, its history is confusing, long and just a whole can of worms. One dealt with in "A re-description of the teleosauroid Macrospondylus bollensis (Jaeger, 1828) from the Posidonienschiefer Formation of Germany".

To give you the abridged version, the holotype of Macrospondylus bollensis was found all the way back in 1755 (meaning it was discovered so long ago even Napoleon wasn't born yet) and quickly recognized as some sort of crocodile relative. It was named Crocodilus Bollensis in 1828, described in the 1830s and given the genus name Macrospondylus in 1831 (and then again by a different author in 1837, seemingly independent of the previous study).

Being this old, of course the fate of Macrospondylus would be shaped by historical events, specifically the German revolutions of 1848–1849, when a fire set by revolutionaries in Dresden grew out of control and spread to the collection, damaging but thankfully not destroying the fossil. Chaos ensued unrelated to that as various researchers proceeded to lump Macrospondylus into either Teleosaurus, Mystriosaurus or even Geosaurus before circling back to Crocodilus, eventually settling on Steneosaurus in the 1960s. Scientists did eventually grow wise to Steneosaurus being an overlumped wastebasket of a taxon, but this was not fixed until 2020 when this gordian knot was hacked to pieces once more, resulting in the revival of Macrospondylus.

Keeping all this confusion in mind, recent work including this paper still finds that Macrospondylus is actually the most abundant Toarcian teleosaur and especially common in Germany (no doubt thanks to the Posidonia Shale, this doesn't necessarily reflect how things were at the time). In terms of ecology, Macrospondylus may have been a long-snouted generalist, being able to consume a much wider selection of and overall bigger prey than some of its rarer relatives. Size might also have been a factor, since large Macrospondylus reach up to 5 meters in length and would therefore have access to more robust and larger prey. Its wide distribution might also suggest that it was less picky than other teleosauroids about where it lived and though previously suggested to have been more marine, this new study seems to favor the idea that it was still fairly amphibious throughout its life. This is interesting given that the Posidonia Shale, where so many specimen are known from, is a pelagic off-shore open ocean environment, with the potentially more terrestrial Platysuchus and the shallow water Plagiophthalmosuchus being much rarer. Of course, there is always the possibility that this idea of Macrospondylus being super common is skewed simply by the preservation and the excavation at Holzmaden, which as said before might not reflect the state of the entire species population.

The metabolism of Notosuchians

Back to something less constrained to any specific taxon, we got "Revisiting the aerobic capacity of Notosuchia (Crocodyliformes, Mesoeucrocodylia)",a paper on notosuchian metabolism, which is one of those things that might surprise people unfamiliar with them.

Of course Notosuchia is the great post-Triassic terrestrial radiation of the crocodile-lineage, bringing forth a great diversity of land-dwelling froms from small omniv, ores, bulky herbivores and even lanky carnivores. Despite this, it might come as a surprise that they were in fact not "warm blooded". This is again reinforced by this months paper by Sena and colleagues, who recover that their mass-independent maximal metabolic rates lie somewhere between modern crocs and monitor lizards (which again fits with previous studies on the matter). This means that fitting with their anatomy and lifestyle, they were more active than modern crocs and able to sustain more vigorous activity. Being ecto-thermic, they were still dependent on outside temperatures to heat them up before they were able to really take things to their fullest. Consequently it has also been hypothesized quite a bit that to cool down, they might have entered burrows later in the day.

Now, for what I'm guessing all five of you that made it this far have been waiting for. The newly named crocs....which I didn't have time to make dedicated posts for. Look shit sucks alright, weekends have been really brief this month and I feel very tired.

Pattisaura: A new sphenosuchian from Texas

Getting us started on Pattisaura, a new genus of "sphenosuchian" (I told you I'd come back to them) from the Late Triassic Cooper Canyon Formation of Texas. Described in "A new crocodylomorph (Pseudosuchia, Crocodylomorpha) from the Upper Triassic of Texas and its phylogenetic relationships", this little guy generally represents what one might see as a quintessential sphenosuchian. A somewhat body pointed skull with large eyes, terrestrial habits, long and slender legs, a far cry from what we tend to associate with crocodylomorpha today.

The name Pattisaura was coined in honor of Mrs. Patricia Kirkpatrick, who's family has let paleontologist look for fossils on their farm (gee I wonder why that name sounds familiar) and the species name gracilis derives from....I mean do I even need to say it?

Unsurprisingly, the phylogenetic analysis of this study shows that Sphenosuchia is paraphyletic and doesn't actually form a single clade, instead simply representing a series of consecutively branching early crocodylomorphs. What can be said is that Pattisaura seems to clade with Redondavenator.

While perhaps unassuming in size or ferocity, little Pattisaura is nonetheless an interesting addition to the pseudosuchian fauna of the Cooper Canyon Formation, which has previously yielded the remains of the phytosaur Machaeroprosopus, various aetosaurs including Desmatosuchus, Aetosaurus, Typothorax and Paratypothorax, poposauroids like Shuvosaurus and the iconic Postosuchus alongside many other Triassic classics such as drepanosaurs, silesaurids, lagerpetids, coelophysoids and more.

Thilastikosuchus: Brazil's oldest notosuchian

And the final one for this month is Thilastikosuchus scutorectangularis (mammal crocodile with rectangular scutes) described in "Anatomical description and systematics of a new notosuchian (Mesoeucrocodylia; Crocodyliformes) from the Quiricó Formation, Lower Cretaceous, Sanfranciscana Basin, Brazil". This little guy, and I mean little as it is based on a juvenile specimen, was recovered from the Early Cretaceous Quiricó Formation of Brazil and represents a new member of the obscure family Candidodontidae.

To give a brief description, Thilastikosuchus was a small, slender-limbed animal, although admittedly we only have a juvenile to go off from. Its teeth are prominently heterodont, meaning that rather than having jaws filled with relatively similar conical teeth its dentition was a lot more diverse, specifically consisting of subconical incisiforms and molariforms with multiple cusps. The armor of the body, as the name suggests, is rectangular with a smooth outer and back edge, eventually transitioning into the square osteoderms of the tail that possess a prominent keel down their middle. As with most notosuchians, there were only two rows that run down along the spine, rather than the more complex armor seen in modern crocodiles.

Perhaps most interesting are the phylogenetic and evolutionary implications of this animal. Thilastikosuchus is the oldest known notosuchian from Brazil and perhaps even the oldest notosuchian of all of South America, which might have big implications for the groups evolution. It is placed as a member of the Candidodontidae, a family coined to include Candidodon and Malawisuchus but not always regarded as a distinct group throughout publications. This new paper specifically places them at the very base of Notosuchia, branching off even before Uruguaysuchidae and Peirosauria. Given the very mammal-like teeth of candidodontids, this raises the question whether or not such dentition was simply convergently evolved by them and sphagesaurids (assuming their position amongst notosuchians holds true) or if its the ancestral condition that was later lost by groups such as uruguaysuchids and baurusuchids. It also adds an interesting aspect to the diversification of the group. As things stand, the oldest known notosuchian is Razanandrongobe from the Jurassic of Madagascar, but this taxon and its significance are poorly understood. With this new paper, we definitely see a clear diversification of notosuchians in the earliest Cretaceous through candidodontids, another radiation later in the Albian with uruguaysuchids and peirosaurs and a final burst in diversity towards the end of the Cretaceous with the numerous forms known from the Bauru group.

And now for the colored version! Well, base colors at least, I'm going to have to look at a *lot* of tutorials to get the full coloring on this done. Eowenah is very, very iridescent. Dazzlingly so! Even her bones are iridescent due to the microstructures within them, like an abalone shell! So yeah, it'll be a while before it's fully done. I've never been good at painting, so this'll be interesting.

Since there's a character limit, and because I am incredibly lazy, I will link to the DeviantArt post for the full description.

ODDYSEUS_MISSION_AE#1744

Sample obtained from the Odysseus mission, sent to gather information about the planet Kepler-138d, a super-earth water world characteristic for its dense, water saturated atmosphere, and whose clouds occasionally appear green.

The mystery of these green clouds has finally been resolved with this analysis of samples that were collected from one of these green clouds as the rover descended into the atmosphere, 15km up in the clouds.

A diverse community of cyanobacteria-like phototrophic microbes (described as Ambrosiasphaera sp.) seems to be responsible for the unusual color of the clouds. These microbes, alongside the many others in the floating ecosystem they help support, seem to have developed hydrogen filled membranous organelles to float over the dense atmosphere. They also seem to have developed a cell wall with an unusual microstructure, extremely water absorbing to take advantage of floating droplets of water.

Some species seem to have developed predatory lifestyles, feeding on the plentiful Ambrosiasphaera chains, here seen one of these lifestyles, here seen one with one of the most unusual ways observed to catch and consume prey (described as Flagellovenator sp.). It floats passively with its flagellum extended, until it comes into contact with something. The appendix is covered in hairs not unlike those on the feet of Gekkonids, able to stick without any sticky substance needed. Once captured, it's bivalves cell wall opens and an amoeboid body penetrates the cell wall and starts digesting it's prey.
