The idea started as a journal club run by @siobhane13.bsky.social in September 2023 and eventually morphed into a lab wide paper at @acadresearch.bsky.social.
It was a lot of fun working with the group and co-leading with Dr. Roberta Davidson. I would love to hear your thoughts.

🧬 📜 New paper alert! 📜 🧬

We review recent literature that use ancient DNA methods in the analysis of archeological artefacts. We hope this will be a useful resource to improve the inclusion of ancient DNA methods into the study of ancient artefacts.

The necessity for authentication of ancient DNA from archaeological artefacts
The study of ancient DNA (aDNA) has revolutionised the fields of archaeology, human evolution and paleoecology, offering new insights into the past. I…

Had a fantastic time meeting great people and learning about exciting aDNA research! Thanks @mattiassherman.bsky.social and team for organising a great event and giving me an opportunity to present my work.

Very happy with how our Ancient Canines Symposium went yesterday which we organised as part of the London Ancient DNA Network!! Such good talks (and pub chats) for the first of many events to bring together our local #aDNA community!

The current slide entitled "The Last Wolf" shows historical illustrations of wolf hunting. Dr William Marsh standing behind a Natural History Museum lectern presenting his work on ancient dogs. The current slide entitled "Background - Magdalenian at Gough's Cave" shows geological scale temperature fluctuations and a map indicating the location of Gough's Cave.

The current slide entitled "Conclusions" shows the different conclusions drawn from his work as well as a picture of an adult dingo caring for its pups.

Since your reads are so short, even a smaller Kmer db would struggle with classifying them. And smaller kmer db come with more false classifications as well.

Your approach is perfectly fine. You could use the classification to remove reads from taxa you are not interested in.
My opinion is that the database is more important than the classifier. If you are happy with the database, I’d stick to that.

Very excited to share the first paper from my PhD thesis. It was a pleasure to work with such amazing people. Check out the thread and paper below. Keen to hear your thoughts.

Congrats to @shyama-mama.bsky.social for his first first-author PhD paper! 🥳

Very keen to hear what #aDNA researchers think of the approach...

The method is relevant for #aDNA sequencing data from eukaryotic organisms, which are typically heavily contaminated by exogenous sources of DNA. 🧵1/n
