New Paper Alert!! Tessa Page and others show how corals deal with low or unbalanced nutrients www.nature.com/articles/s41...
The main issue is lack of P that causes them to upregulate P-transporter genes and likely consume their symbionts and bleach! 🪸🌊🧪

Great to finally hold this in my hand! Pleasure to work with @amoeba-lab.bsky.social and Ros Rickaby in editing this issue of Elements: Biomineral Geochemistry. Thanks also to all the authors who made such a great set of articles! www.elementsmagazine.org 🧪🌊⚒️

!New Paper Alert! Matrix independent and interference free in situ boron isotope analysis by laser ablation MC-ICP-MS/MS pubs.rsc.org/en/content/a.... In it we use our Neoma MC-ICPMS/MS to overcome the complexities of measuring boron isotopes by Laser Ablation in carbonates and other minerals. ⚒️🧪🌊🪸

Cross plots of d11B reference value vs. what we measure using Laser Ablation on our Neoma MC-ICPMS/MS. All the data lie on the 1:1 line showing that we can get accurate d11B data using laser ablation on a range of matrices from carbonate to silicate when normalised to NIST 612 glass.

Mass scans from m/z 9.7 to 11.1 for the Neoma MS/MS, base Neoma and Neptune when ablating carbonates. The Neptune shows an elevated background due to scattering of Ca and Ar 4+ ions. This is reduced in the base Neoma and entirely eliminated in the Neoma MS/MS. We think this is because the formation of Ca4+ and Ar4+ is reduced in this design of MS and scattering of this multiply charged ions is reduced once Ar and Ca are cut out by the pre-filter.

This shows the problem with laser ablation boron isotopes in carbonates on our Neptune MC-ICPMS. It shows a mass scan from m/z 9.7 to m/z 11.1 with peaks at the boron masses 10B and 11B. Rather than being a flat line - the baseline is elevated around boron 10 (and 11) due to scattering of 4+ Ar and Ca.

Very pleased to have co-edited the latest version of Elements Magazine (www.elementsmagazine.org) "Biomineral Geochemistry" with @amoeba-lab.bsky.social and Ros Rickaby. Topics range from controls on CaCO3 polymorph to the role of amorphous intermediate phases and "vital effects". 🧪🌊🪸⚒️

On topics as diverse as stable isotope geochemistry, amorphous precursor phases, inferring ion transport processes, and biomineral polymorph selection. Overall we aim to highlight how the 'vital effect' problem can not only be overcome but also leveraged to understand the organisms we work with!
