Thank you Nina!!

Evaluating the Reliability of Grain‐Size Sorting for Organic Biomarker Analysis We investigate the potential of using grain-size sorted marine sediments for biomarker analysis GDGT distributions are consistent regardless of grain-size sorting, and fine-grained sediment fract...

Can global archives of fine-grained marine sediments be “resurrected” for biomarker analysis? The answer is (mostly) yes!

New paper alert 🚨🚨 Here we posit a non-linear relationship between Indian Summer #Monsoon (ISM) intensity & marine productivity in the Bay of #Bengal: extremely weak & strong #ISM states of the last 22,000 yrs were *both* associated with sharp disruptions to primary production! (1/6)

Spotted this unusual vessel at NOCS today - these are new fuel-efficient, onshore-controlled vessels that will eventually be capable of working with no personnel offshore (!) whilst also consuming solely renewable fuel such as ammonia.

The agricultural plastic paradox: Feeding more, harming more? Agricultural plastic film mulch (PFM) covers ca. 50 million hectares of the Earth’s surface and has revolutionized agriculture, particularly in arid a…

Really pleased to see "The agricultural plastic paradox: Feeding more, harming more?" led by Kai Wang at CAU published. We contextuliase negative tradeoffs of agricultural plastic use with the societial benefits delivered, showing the need for "zero-leakage" rather than "zero-use".

Oh wow, big changes Stefan - you'll be missed at BBK! What's up next for you?

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.

!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. ⚒️🧪🌊🪸

75% of US scientists who answered Nature poll consider leaving More than 1,600 readers answered our poll; many said they were looking for jobs in Europe and Canada.

We polled Nature readers to ask if they were thinking of leaving the US for jobs abroad. Three-quarters of them (who said they were US-based scientists) said yes. 🧪
