Can we use H isotope offsets among lipids as proxies of algal community composition? New paper led by Antonia Klatt shows that changes with community throughout a year in Rotsee aren similar results from cultures and indicate minimal influence from heterotrophs: doi.org/10.1016/j.gc...

Back in 2019 we screened an obscure lineage of bacteria for a side project and noticed something quite unusual. A quinone, used in cellular electron transport, that looked similar to the type used by plants and algae to perform photosynthesis.

Achieving climate targets is primarily limited by politics, institutions and humans, not technology, solutions or money.

It's values and priorities, about who we are. (1/7)

Call for abstracts #EGU25 on developing new biomarkers! #EGUbiomarker. Abstract submission is now open! Organized by Jingjing Guo, @hallbergpetter.bsky.social, Nora Richter, Addison Rice and myself. tinyurl.com/4422wwr7

Screenshot of the following text:
Lipid biomarkers: novel applications, calibrations and tools for environmental
studies
Lipid biomarkers are valuable tools for reconstructing a variety of environmental processes in modern
and (geological) past settings. We seek studies that develop new lipid biomarkers and methods for
applying biomarkers to modern settings and the geologic past to reconstruct environmental
parameters such as temperature, precipitation, biogeochemical cycles, anthropogenic activities, and
vegetation. These can be studies on the biosynthesis and phylogeny of source organisms, transport and
diagenesis, calibrations to environmental parameters, proxy interpretation and applications to reconstruct past environmental conditions.

It's a wrap! Toni and Theresa have just spent six days carefully sampling sediment cores from lakes Owasco, Neuchatel and Biel for ancient DNA. In the coming months we will see if we find evidence of harmful algal blooms in these systems throughout the past ~12000 years
