Cool PhD opportunity at Uni Bern to work with Petra Zahajska on her Ambizione project Pixel2Paleo, creating high resolution pigment and lipid biomarker marker records from lake sediments 🧪. Apply by Dec. 2:

New co-author paper out today in @pnas.org led by the fantastic Dr. Lubna Shawar!

Lubna breathes new life into the sponge sterol hypothesis with her meticulous organic geochemistry, and the ID of two new sponge-derived C31 Steranes in ~600 Myr rocks. Check it out! 🧪⚒️

Had a great week out on Seneca lake taking samples to test some ideas about the cause of the mysterious Seneca Drums (aka Guns)!

Aside from the “cool factor” of getting to investigate a local legend I grew up hearing about, there are Environmental and water quality implications of the work too.

A new semester means a new round of Sparks Lab TidyTuesday on a Wednesday! This month, one of our students picked the #TidyTuesday Pokémon dataset to visualize. This was my contribution, which explored median stat distributions by primary type. Really fun dataset and a great group exercise!

Take a break from doom scrolling to have a look at this really cool study lead by @fatimagulhusain.bsky.social out of MIT!

I am excited to share our latest work, out now in
@natcomms.nature.com.

We used eukaryotic biomarkers and 18S rRNA genes to examine the ephemeral meltwater ponds of the McMurdo Ice Shelf, revealing pond-to-pond diversity and a biomarker signal for life below the shelf!

This was a neat project to work on, and I enjoyed getting to branch out into some methane isotope work. Thanks @profbobhowarth.bsky.social for suggesting we take a deeper look.

Increase in methane emissions from fossil fuels has been underestimated. Our new PNAS paper just published today:

Fantastic article on why cuts at NSF are harmful to everyone. For scientists, a thorough collection of evidence of NSF's impact. For everyone else, a small slice of the incredible number of everyday things NSF-funded research has improved. By Prof. Paul Bierman.🧪

We are really proud of this one, and hope the bluesky-verse finds it interesting!

We also owe a huge debt to the late Prof. Nic Beukes who led the CIMERA-Agouron project and was instrumental in the retrieval and sampling of these cores. 7/7

So, our study pushes that back by over 100 million years and adds to the growing body of evidence that the oxidation of the oceans and the atmosphere were at times decoupled, and likely played out in a tumultuous non-linear fashion after the onset of oxygenic photosynthesis. 6/7

It was previously thought that an aerobic nitrogen cycle was established closer to 2.31 Ga in step with the final stage of the Great Oxidation Event where atmospheric oxygen contents rose above the threshold required to inhibit the mass-independent fractionation of sulfur isotopes (S-MIF). 5/7
benuveges.bsky.social
This coupled with a new age for one of the cores we recently published in a paper led by @alexiemillikin.bsky.social, means that this ocurred in the ocean by ~2.43 billion years ago. 4/7

What we found were strikingly big +ve δ15N values correlated across cores separated by hundreds of kilometers, indicating the extensive operation of incomplete water column denitrification. This indicates a largely aerobic nitrogen cycle, and the predominance of nitrate in the surface ocean. 3/7

I was lucky enough while I was at MIT to work with a set of cores drilled in association with the CIMERA-Agouron Great Oxidation Event and Biomarker Drilling project. In this paper, we report carbon and nitrogen isotope data from these cores taken across the Transvaal basin in South Africa. 2/7
