Very excited to share our study of an ancient environmental genome extracted from lake sediment! It originates from a brown bear that lived around 9,600 years ago close to the last ice-sheet remains in northern Sweden, and has an unexpected mitochondrial haplogroup. 1/7 www.pnas.org/doi/10.1073/...
Kæmpe RIP, mand.
Jeg skal til at bruge mås’en som tidsenhed.
I know nothing about physics but if a cow can be thrown around like it’s nothing as in that tornado documentary, Twister, I’m sure a brachy can become airborne as well.
Wild to think that tornadoes and large sauropods co-existed for millions of years. Even wilder to consider how, at one point, some insane EF5 likely picked up a fully grown brachiosaur and hurled it across some prehistoric plain.
Easily one of the most fun reads (along with the pasta paper) of 2025. Knot kidding.

Finishing a PhD thesis is like time. It's a flat circle.
It's a pancake flat circle of endless: "I'm going to make it" - "fuck I'm not going to make it" - "hey, I'm actually going to make it" and "fuck, I'm never going to make this"
Out today is our paper 'Genomic history of early dogs in Europe', in which we uncover the identity of the dogs that lived in Europe before agriculture—during the Paleolithic & Mesolithic periods: doi.org/10.1038/s415.... A thread ⬇️ (10)

Roses are red
Bet you can’t take this one step further
Vent - blev der produceret Walkmen frem til 2005??
"Underland: A Deep Time Journey" by Robert Mcfarlane is a fantastic read and listen.
"[...] genetic sex estimation is notoriously difficult in living porcupines, due to their internal genitalia and defensive spines [...]"
"Sex determination in living porcupines is not an easy task, luckily genetic sex determination using DNA is a relatively simpler task."
This ought to be fun…
Yes
Looks like something out of a pinhole camera.

A north arrow. This one is drawn as an actual arrow with fletchings and everything. The shaft is tapered down to the barbed point. At the tip is written "Nord" in nice cursive script.
#NorthArrow Frants Frederik Jonathan Møller 1811.
Good dynamism. Like the detail on the fletching. 8/10
🏺 🐺 🐕 My pet theory is that wolves' musicality and ability to sing WITH PEOPLE is a key reason why we were mutually attracted - domestication through shared aesthetic sensibility, not merely economics of being good at hunting or guarding or pulling sleds...
(this is going to be in #Matriarcha 📚)
I'm singing with my dog on a near-daily basis.
“Aa, det fille, det falle i min Hovedskalle.” sagde Kyllingen. “Lad os løbe!” sagde Hanen.
