I had the opportunity to interview @matthewcollins.bsky.social on his recent visit to @cenieh.bsky.social. The podcast is out now! It's a fun chat about #palaeoproteomics and the ways we can study ancient #proteins at Atapuerca! Thanks Matthew for the chat! www.ivoox.com/en/paleoprot...

I am starting a computational lab at LIOS, Riga, Latvia, and going to recruit a few people. Please DM if you are interested in a postdoc or PhD position in my Metabolic Research Group within the TARGETWISE project. I can highly recommend Riga, it is a beautiful city with very good living conditions.

And still probably the proceedings will go through our free and transparent peer review system!

Wonderful time with @cenieh.bsky.social looking at the sites @fatapuerca.bsky.social !

Catch Dan, one of our #FestivalOfArchaeology 2024 stars, as he grills Claire with some awesome and curious questions!

Stone Age farmers’ households passed from mother to daughter Moms and daughters were at the center of the family in ancient Çatalhöyük, ancient DNA and archaeological evidence suggest

The nature of Neolithic society is one of the most debated topics in archaeology–a debate that's almost impossible to settle w/ conventional methods alone. Now, new DNA data from a site in Turkey called Çatalhöyük points to a significant role for women: www.science.org/content/arti... @science.org

On 25 June 1997, pyroclastic flows from a sudden dome collapse at Soufrière Hills devastated several villages. 19 lives were lost, and 5 others severely injured. We remember them today and reflect on the impact of this tragic event in our shared history. #Montserrat #SHV30

The Hunt for Proteins in Dinosaur Fossils Reports of peptide sequences in 2005 have ignited controversy and interest in paleoproteomics.

Carolyn Wilke: The hunt for proteins in dinosaur fossils. ACS Cent. Sci. (2025) pubs.acs.org/doi/full/10....

6️⃣/ After three decades in this field, I appreciate Schweitzer's approach of trying to disprove rather than prove hypotheses. The systematic search for biomolecules her work sparked has revolutionised #palaeoproteomics, regardless of the T. rex verdict. Science marches on! 🦕

5️⃣/ Taylor's new Edmontosaurus sequences are independent replication, but their tryptic peptides seem too clean cut , not the ladders with "ragged ends" I would expect from ancient proteins. This pattern resembles fresh samples, raising contamination concerns despite careful controls.

4️⃣/ Cross-linking chemistry may be key - @jwiemann.bsky.social's "chocolate colour gradient" approach uses visual cues to identify promising fossils. Iron-mediated reactions could create stable protein networks resistant to degradation.

3️⃣/ However, @carlipeters.bsky.social's #ZooMS work in 30°C Australian caves found 70,000-year-old collagen from extinct fauna. This challenges our models and suggests preservation mechanisms we don't fully understand. Environmental factors clearly matter more than temperature alone.

2️⃣/ The core issue: can collagen survive 68 million years? Our (Colin Smith's) old temperature-degradation models suggest not - fossils above 20°C shouldn't yield detectable collagen after 15,000 years. Yet Hell Creek formation temperatures were much warmer historically. 🌡️

1️⃣/ Fascinating new piece in @cenmag.bsky.social on the hunt for dinosaur proteins! The 2005 Schweitzer T. rex collagen reports remain contentious after 20 years. Recent Edmontosaurus data adds fuel to the debate, but I cofess I remains cautiously sceptical. #palaeoproteomics

6️⃣/ After three decades in #palaeoproteomics, it's inspiring to see how platforms like Bordeaux are pushing boundaries whilst maintaining rigorous scientific standards. Caroline's work ensures these powerful tools serve both scholarship and heritage preservation. Chapeau! 🎩

5️⃣/ The @univbordeaux.bsky.social team's collaborative ethos shines through - working with museums, conservators, and researchers worldwide. This symposium itself demonstrates Caroline's vision of making advanced analytical techniques accessible across disciplines. #heritage #archaeology

4️⃣/ Caroline's work exemplifies why @univbordeaux.bsky.social has become such a pivotal centre for heritage science. The platform's ability to bridge analytical rigour with cultural interpretation sets the standard for the field. Brilliant presentation! #archaeology #palaeoproteomics

3️⃣/ The "effect of treatment" aspect is particularly crucial for conservators - knowing how previous interventions have altered artworks helps inform future preservation strategies. #massspec provides that temporal roadmap through chemical fingerprints.

2️⃣/ Love how Caroline emphasises the holistic approach: it's not just about identifying materials, but understanding modifications, tracking changes over time, and revealing the human stories behind cultural objects. This is analytical chemistry at its most humanistic.

Caroline in a patterned dress presents to an audience in a tiered lecture theatre with curved wooden seating. The projection screen shows a colorful diagram with molecular structures and text about "MATERIALS (ID, Modification)" including bullet points about understanding artist intention, artwork changes, treatment effects, and societal context. Attendees sit on wooden benches taking notes, with laptops open throughout the amphitheatre.

🧵 Thread: 1️⃣/ Caroline Tokarski delivering a masterclass on how #massspec revolutionises our understanding of cultural materials! Her slide perfectly encapsulates the multifaceted insights we can extract - from artist intention to societal context. #teammasspec #heritage

The historical irony isn't lost as Rembrandt's anatomy lesson is juxtaposed with #teammasspec in an amphitheatre designed for anatomical dissection.

Figure 2 of the manuscript. Data availability in palaeoproteomics. A) Percentage of ZooMS and shotgun palaeoproteomics studies with available datasets. Preprints and papers that did not produce any data were excluded from this calculation. B) Number of palaeoproteomics datasets in online repositories (since 2010). ´Other´ repositories include Dryad, Figshare, Github, Mendeley Data, and the OSF Framework. The dataset was compiled by manually going through the list of publications compiled for Figure 1 and checking raw data availability. This figure was made in R v.4.4.2. with R Studio v.2024.12.0+ (R Core Team, 2023) using ggplot2 (Wickham, 2016).
