I am so happy to co-author this #preprint review on archaeal tetraether lipids, aka #GDGTs, as marine paleoenvironmental indicators led by @lipidorama.bsky.social and @climategordon.bsky.social: doi.org/10.22541/ess... @cerege.bsky.social @climatecerege.bsky.social #TeamArchaea 🧪 ⚒️ 🌊 #PaleoSky (1/4)

Nina Davtian (that's me!) at her work office, with the laptop screen showing the header of her co-authored preprint by Elling and Inglis et al. Earth and Space Science Open Archive (https://doi.org/10.22541/essoar.176409484.44403346/v1) with her name highlighted in the author list—Nina is the third author of the list. Nina is holding a mug on which the text reads « 2nd international GDGT workshop September 2023, Zürich ».

Our new preprint review on archaeal lipids (GDGTs) led by @lipidorama.bsky.social and @climategordon.bsky.social are live! Fresh updates on these amazing lipids and their environmental applications, from the 2nd int'l GDGT workshop (led by @cindydejonge.bsky.social, Francien Peterse & David Naafs).

Very interesting preprint from @matthewcollins.bsky.social @jessiehendy.bsky.social and others on experimental foodcrusts and recovered proteins to identify the ingredients. It's complicated. www.biorxiv.org/content/10.1...

An unclean slate, discrepancies between food input and recovered protein signal from experimental foodcrusts

Organic residues are a rich source of biomolecular information on ancient diets. In particular, foodcrusts, charred residues on ceramics, are commonly analysed for their lipid content and to a lesser ...

🧬 Game-changer for ancient bone analysis: AutoZooMS automates species ID using robotics & mass spec! Study at Grotte Mandrin (42-44Ka) ID'd 1200+ samples, revealing new taxa (bears, mammoths) & human remains. Future of archaeology = robots doing the heavy lifting 🦴🤖 #archaeology #ZooMS

A technical laboratory workflow diagram divided into "Protein Extraction and Digest" and "MALDI spotting and analysis" sections. Left section: Bones are placed in 48-well MTP plates, treated with 0.95mL 0.6M HCL, transferred to 96-well filter plates (10kDa/30kDa MWCO), followed by 3x centrifugation and ABC buffer addition. Right section: Samples transfer to 96-well MT plates, undergo trypsin digestion (0.1-0.2µg per sample) at 37°C, diluted with matrix solution, spotted onto 384 MALDI plate. Process concludes with a mass spectrometry spectrum showing protein peaks and bioinformatics analysis. Each step marked with gear icons requires manual intervention for centrifuge/incubator transfers. The workflow enables processing >1000 samples within 24 hours using Hamilton Microlab STAR system with 8-channel and 96-channel Multi-Probe-Head capabilities.

Simple, but simply scary? Anonymising job applications achieved gender parity in 🇨🇦 Biochemisty Dept from 17% in the previous 10 years (5 hires) to 80% in the subsequent 4 years (5 hires). Christian, S. L. et al. Preprint at biorXiv doi.org/10.1101/2024... (2024). Report in Nature

How a biochemistry department used redacted job applications to achieve gender parity

Anonymizing job applications before shortlisting helped to boost the number of women appointed.

NatureRevMCB by Ryan Paterson, Palesa Madupe & Enrico Cappellini 3.8M year old horse 🐎 tooth 🦷 yielded 60+ proteins covering ~10k amino acids. Single-molecule sequencing tech a game-changer? 💀 Decolonization & democratization of human evolution studies 🦕 ? #paleoproteomics #evolution

Paleoproteomics sheds light on million-year-old fossils - Nature Reviews Molecular Cell Biology

Ancient proteins can provide phylogenetic information at a timescale that supersedes ancient DNA. Paleoproteomics could thus provide invaluable evolutionary insights, including into human evolution.
