Have you ever wondered why pumpkins are never purple or blue like other plants? 🎃🌈

While most plants can produce pink, blue, and purple pigments (thanks to anthocyanins), the Cucurbitaceae family 🍈 🍉 🥒have lost all the pathway genes to produce these pigments.

I'm on the BBC talking about (how we won't be) evolving into crabs 🧪🦀

Also features Matt Wills (my academic older brother) and Ned Suesat-Williams (of the crab museum!). Unfortunately they were in London and I on zoom, so there was no time to tell Ned to join here

Hannah and Dara investigate why nature has evolved the humble crabs so many times.

Anyone in #paleontology or #geology have a recommendation for a lay-person friendly book on the Permian extinction?

If someone in your life has gently, tentatively, or too-casually suggested you should “maybe talk to a therapist about it,” I’m here to second their opinion.

Go to therapy!

As research demonstrates, innovation is not caused by sudden inspiration, but by different ideas, perspectives, and approaches coming together. We need diversity in science.

I absolutely love the fact they've Pokemon-ised the museum staff, for the upcoming Pokémon partnership with the Field Museum. Museums, take note.

Throne room works too. Whenever I’m there, it’s the closest thing I do to worship.

💯it seems so obvious to me and should be obvious to anyone who values evidence-based medicine.

Extinct Pleistocene carnivores were diurnal and had high metabolic rates:
"Only basal metabolic rate and diurnality are robust predictors of extinction, even after accounting for phylogenetic and trait uncertainty"

Might make my own little audio lesson for last minute cramming on the flight over.

"Ok, Sarah. Repeat after me.

Would you like a squid zine?
イカのジンはいかがですか?

Which way to the squid?
イカはどこですか?

Thank you for the squid!
イカありがとう!

No octopus please, I only like squid.
タコはやめて、イカだけが好きです。"

Very pleased to see our study that formally quantifies the society of zebra finches. They have different types of relationships, and these form tiers, but they do not form a multilevel society.

This was a very nice collaboration with great colleagues.

Same! This is a genuine PSA. I bought into the stigma against fish and thought they were boring. It’s perhaps the thing I’ve been most wrong about.

They have so many beautiful patterns and colors! So many weird ways to arrange bones! So many superpowers!

Don’t let anyone tell you fish are boring.

Fish cranial kinesis model is now listed in my Etsy shop! Hopefully useful for showing the mechanism that opens and closes a teleost fish's mouth.
