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.
tinyurl.com/4hm42zr8 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.

🧬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

✨ 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.

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.

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!

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/…

TIL eagles have barbed tongues. 🦅

*ahem*

BARBS. ON. THEIR. TONGUES.

#Birds are so metal…
A thread 👇👇#scicomm I study teeth.. but when animals lose their teeth through evolution they come up with other nightmarish solutions and I love them all.

Herons and Egrets have harpoon tongues.
