✨ Day 1 of #BoneFacts

Bone is a living tissue bone is NOT dry bone is WET. WAB.

So how come you need lubricants when you need a bone saw, or what does it mean to be “bone-dry”

This is the bone wetness thread no one asked for! 💁🏽‍♀️ 🦴 ☔️
Okay so what’s the deal? You’ve seen bones on display maybe even found a couple and they didn’t strike you as particularly moist.

But trust me bone is WET💦

The water content of bone varies from 12-31% depending what bone, what animal and how old it is.
This is because bones have marrow, cells, nerves and blood vessels. All of those are components that make the ‘bone organ’.

Bones do SO MUCH more than support us, but that’s for another day’s #BoneFacts!
Even if you want to ignore all those parts and you are some kind of hedonistic bone purest. (If so hi let’s be friends) and you say to me-

“But Yara those aren’t TRUE bone” okay then you are talking about bone as a tissue maybe you are referring to the minerals ONLY.
WELL GUESS WHAT. Those minerals are held in place by collagen. And colleges is about 60% water.

No water no bones.

BONES ARE WET AF.
When an bone having vertebrate dies and decomposes often WHATS left are the inorganic part of bones. Just the mineral.

This is why dry bones are so much lighter but also more fragile than YOUR skeleton.

Your bones are strong because they are wet. They can flex!
Bones are wet on every level from the cells that make them to the tissues, to the skeletal organ that supports you. #BoneFacts
9 days till I defend my PhD about bones! Tomorrow’s #BoneFacts maybe REALLY BIG or really smol.
Oops forgot to define “bone dry”.

When bone dries out it is super porous and basically PULLS moisture from wherever it can. This is why dry bone sticks to your tongue- fossils too! @CoastalPaleo demonstrates!

I assume this is why it’s called bone dry. So dry it PULLS water!

I use twitter to talk science, fossils, and scream about bones.

So why am I terrified to share this? This too is an unfortunate part of science...

Two years ago @Koskinonodon and I reported our advisor, Robert Reisz, for bullying and harassment.

The letter above is to our paleontological community. Really to all scientists, this is a major problem in the system. Giving power and applying pressure, in the name of meritocracy.

It broke me several times.
It is not a few bad apples, its flawed by design.
In this thread I will talk about my personal experience.
So obviously, Content warning // Sexual harassment and bullying.

I hate that THIS will be my longest twitter thread.

🧬Time for some #CatScience!🧬

Siamese #Cats are born white and gain their colour through their life!

It’s based on.. wait for it TEMPERATURE 🥶 ❄️

Siamese cats are temperature dependent albinos! A.K.A a live kitty heat map!

A thread featuring my cats🧵 👇🏽 Siamese cat sitting on a wi...
New born Siamese Cats are almost completely white!

I’ll keep the genetics simple here so stay with me. Siamese cats have a specific gene that blocks colour 🛑

BUT the enzyme made by this gene only works at a certain temperature. ~101F (38-39.2 C) a cats body temperature! Image
The womb is pretty warm. Kittens come out white, but as they cool the colour blocking begins to stop working. Staring with the extremities!

Look at their little noses and ears they get dark first because they are the coolest part of their body.

Friggin adorable. Siamese kitten with a dark ...

Worth a read. I am not going to speak for Mexicans but I can only imagine the frustration.

You don’t have to take a fossil out of the country to make it inaccessible to its people. This is shady af and that the journal is backing them up says it all.

sciencemag.org/news/2021/04/a…
As an Egyptian I know what it’s like to have parts of your heritage taken out and then only a fraction of your family can see them.
Don’t tell me they are safer elsewhere.

A- that’s racist
B- spinosaurus 🙃

ITS OUT!✨

WE DISCOVERED A NEW WAY TO IMAGE FOSSIL CELL SPACES!

Yes, that spinning cell space is 400 mill-years-old, also turns out fossil fish gave us bone metabolism!

PhD chapter 1 is out:bit.ly/2PoUY3J

If you share ANY of my stuff on this site, share THIS THREAD!
This is my first ALL FISH paper.. what have I become?!

For the quick land well written lowdown check out the @Natgeo article by @Laelaps with bomb art by @BrianEngh_Art: nationalgeographic.com/science/articl…

For the continued ramblings of an overly excited scientist READ ON!

STORY TIME!

Many of you may have read the @nytimes article by @asher_elbein: nyti.ms/3caRvyn

Some of you may want more context as to how "normal" paleo fieldwork became a collapsing museum rescue mission AND case study in how to #DecolonizePaleontology

📸:Mariem Hbaieb
First, I'd like to shout out @nytimes and @asher_elbein for giving us a public platform for this.

This article has been in the works since January 2020!!

Also check out quotes from @emmadnn and @mauritiantales. These are THE people to follow!

nytimes.com/2021/03/22/sci…
The fact that it seems to coincide with certain ethically dubious fossils being published recently is a coincidence but also emphasizes how often this happens.

OH HEY THERE I’m Yara the Osteological Oligarch, and my face just got distributed across Berlin!!

So let me tell you a little about my PhD research on bone evolution (and bonus fossil virus evidence) in English! 🦠 🦴 💀 ✨

#Osteology #SciComm
Seriously tho..
MOM LOOK IM CENTERFOLD!!

My mother can’t read german.. I can’t read german.

It’s titled “the time traveler”.. either millions of years back or a year forward are my options tbh

But if you CAN read german here is the link: museumfuernaturkunde.berlin/sites/default/…
Ahem.
So I tweet about all kinds of natur-y things, many of you might wonder whats she actually study?

Right now, B O N E S🦴

While this was mostly for the 📸 I DO rely heavily on mammals for my research because humans and mice have been studied the most on a bone-cell level!
