Bring us net zero. As fast as possible! Free energy forever plus we save this beautiful planet, and create 1000s of jobs too.
Don’t be nervous, be ambitious!

Me too. I also find these huge conferences rather soul-destroying and hard to navigate. Parallel session hell. Smaller conferences are much better.

Wow congrats!! That's really awesome, MSCA is the best!

Was just saying the same thing, it's just so disgusting! Please stop!

Is raduis French for radius?!!

This may have been in 92 AD, during the time of the emperor Domitian, when Suetonius mentions the loss of an entire legion during a battle with the Sarmatians. One of my students (pictured below at the bottom of the earlier picture) has been lucky to be working on the site for several months!

The skeletons have wounds from swords, lances; blunt trauma. The archaeologists working on the project think that those killed were probably been part of a military operation, the Danube campaigns, that ended in catastrophe.

Thanks for your comments Jonas!

For material with low collagen. Yes, this is one of the potentially most exciting areas. A single sample from a low coll bone is risky, collagen sometimes varies in a single bone. A whole bone non-dest. extraction has a chance to extract trace proteins, making it better as an approach I think.

For checking glue from bone-derived sources (which is rare) we use ZooMS. This is also non-destructive and tells us from the spectra whether there are peaks from more than one source. see Laura's paper www.nature.com/articles/s41... aDNA will also reveal this but is more expensive and less rapid.

Thanks for your comments Sonja. Antlers should be the same as bone/teeth for this. For consolidants, if glues/conservation products, we apply post-purification steps - ultrafiltration or an acid hydrolysis then passing the amino acids through an XAD2 resin column.

Thanks Mike! One of the crazier ideas...It's been a lot of fun to work on.

Yes I saw this this morning. Another heritage building junked. Not listed mind you, but in our minds and memories it was a special place.
Still Dunedin north needs more carparks or something...🤨

Yes. We've dated this human tooth using the ND method. We suspended only the tooth root in water, leaving the crown out, and managed to extract enough collagen for dating. We are testing more teeth, but we can certainly try smaller ones to see how they go in terms of collagen content...

Here's a picture of some of the collagen yields obtained from bones we have analysed.
This was work done as part of a Masters research project by Katharina Luftensteiner in our lab in Vienna (highamlab.univie.ac.at)

Comparison between 14C ages revealed statistical parity between non-destructive and traditional methods across different archaeological samples. This approach provides us with the opportunity to extract biomolecules for 14C without having to damage or destroy valuable artefacts and objects.

This was followed by ultrafiltration to purify the extracts.
The resulting amino acid composition, isotopic values and analytical data support the interpretation that the collagen was consistent with that obtained using destructive protocols.

In the paper we present a novel non-destructive method for radiocarbon dating bone. Routine techniques are destructive. They involve drilling or crushing of bone and teeth. We employed an extraction in hot water at 75-90 C to solublise collagen from archaeological bones without any visible damage.

Defames the journalist who found himself on the call, rather than take the rap himself. Wonder who he learnt blaming all the others from?

I just did mine too, it's a strange and rather horrible feeling to see how much is being sucked up into the AI machine...time, effort, thinking, emotion.

Oh!! 😂 Yes we have a very good university photographer that comes and takes all our photos!

The post is mainly field-based work, sampling for radiocarbon, sediment DNA/proteomics. We want someone with direct experience in archaeological fieldwork (especially prehistoric/Palaeolithic) as well as in archsci methods, although the latter is not crucial and can be picked up.
