@merszym.bsky.social @janetk.bsky.social et al. develop quicksand, an open-source Nextflow pipeline designed for rapid and accurate taxonomic classification of mammalian mitochondrial DNA in sedimentary ancient DNA samples.

I am very excited to present this work to the (sed)aDNA community - and I am looking forward to some cool applications!
If you want to use quicksand, I recommend following supplementary section 8, which demonstrates several use-cases :)
see github.com/mpieva/quicksand for more details

If you’re working with sedaDNA and are curious about large-scale screening approaches, this is absolutely worth a read.
Massive props to the team, super cool stuff!
Cool work from my colleagues @mpi-eva-leipzig.bsky.social just dropped! Merlin Szymanski, @janetk.bsky.social et al. developed quicksand, a fast, accurate and beautifully designed Nextflow pipeline for taxonomic classification of mammalian mtDNA from ancient sediment DNA. doi.org/10.1093/molb...
You know who are not confused, or uncertain, or mealy-mouthed about this? The Germans. Who might have some insight into this matter.
Back in beautiful Leiden and @naturalis.bsky.social today! 🦴💀✨ Wrapped up work and finally got to explore the exhibition—what an incredible spot to dive into the wonders of evolution! 🧬🌿 Feeling inspired
Schön, dass du hier bist 🐔
Way too excited about this! Just packed my MTG LOTR Jumpstart decks into their new home. How cool are these 3D-printed deck sleeves? #mtg #lotr #3Dprint
First seminar for our series 'Human Palaeosystems in Focus' for the new year! Join us tomorrow at 14.00 CET!

Laut CDU ist es blauäugig in Sachsen einen Abgeordnetenausweis hochzuhalten und bei einer Demonstration darauf zu hoffen nicht zusammengeschlagen zu werden. Damit ist dann aber wirklich alles gesagt #Riesa
During a weekend winter walk, I stumbled upon this cool phenomenon—hair ice! It looks like frozen cotton candy, but it’s actually delicate ice strands growing on dead wood when temperatures dip just below freezing. A little fungus is the genius behind this frosty art! #fungifriends

Here are some nice mushrooms
Your birbs are amazing 😍 Would totally get a calendar with them. Sending many hugs from Leipzig 🤍
Spannend! Neue #aDNA 🏺🧬 Analytik an Altfunden: Knochenfragmente aus der Ilsenhöhle bei #Ranis (Thüringen) geben älteste Genome moderner Menschen preis - und zeigen #Neandertaler Genomsegmente eines einzigen Vermischungsereignisses vor 45.000-49.000 Jahren:

New studies out yesterday show when modern humans last mated w/Neanderthals, but it's the details in this paper by @arevsumer.bsky.social @kaypruefer.bsky.social & co. that got me–like a mother and daughter found together after 45K years, or their close relative identified in a distant Czech cave.
I am very happy to share our new paper on the genetics of some of the first modern humans who ever lived in Europe! We sequenced nuclear DNA from 13 specimens from Ranis in Germany, and found that they belonged to at least 6 individuals. www.nature.com/articles/s41... (1/n)
So incredibly proud of and happy for @arevsumer.bsky.social , @leonardoiasi.bsky.social and @mchintalapati.bsky.social, and their two papers that just came out yesterday! 💀❤️🧬
And so incredibly grateful to be able to work with such an amazing group of people. :)
A great 🧵 by @arevsumer.bsky.social👇
I am very happy and excited that our finds from Ranis along with those from the 1930s excavations (now stored at the Museum for Prehistory at Halle(Saale) led to these incredible results! A big Thank You to @arevsumer.bsky.social and the entire team for this amazing work!
Two super interesting papers out today about Neanderthal admixture. Showing it happened less than 49kya. So any modern human remains outside Africa before that date must have belonged to other populations which we presumably don’t descend from??? (I might be wrong though)
‘Mystery woman’s DNA reveals close family ties between Europe’s earliest [sic] people’
Excited to share the groundbreaking work by @arevsumer.bsky.social, who successfully sequenced the oldest modern human genomes ever! 💀 A scientifically thrilling and deeply rewarding project to be part of!
Out today in @sciencemagazine, we've journeyed into our shared history with Neandertals by analyzing over 300 present-day and ancient modern humans, including 59 individuals who lived between 2,000 and 45,000 years ago.

Finally, after 2 years at MPI-EVA, visited our DNA sequencing lab! Lots of cool machines. One of them is called Hamilton: an appropriate name for a robot that kills you at the end of the movie 🔴. Jokes aside, huge thanks to @arevsumer.bsky.social & @elenaessel.bsky.social for the tour!
