@vicgrinberg a number of years ago, I used this photograph in a presentation I gave at a conference in Krakow. I was discussing the mixture of hydrocarbons in the unresolved complex mixture often seen in petroleum and environmental samples (see https://en.wikipedia.org/wiki/Unresolved_complex_mixture). It caused a bit of amusement...

BOGS 2025 is over. Prizes have been given for the Archie Douglas Award best oral presentation and also runner up oral and best and runner up poster presentation. Fear not, we will return and BOGS 2026 will be hosted at Sheffield Hallam sometime in July 2026... watch this space!

And now to the fifth and final scientific session of BOGS 2025. Presentations include: intra-crystalline protein decomposition in fossil shells, using constructed wetlands to address wastewater pollution and primary productivity at the Cretaceous-Paleogene boundary.

After an enjoyable happening last night, the second day and fourth session of BOGS 2025 includes presentation on: wild resource exploitation in Neolithic Europe using biomolecules, oxytetracycline removal from wastewater, understanding coral reef collapse from biomarkers and effect of agricultural plastics on microbial communities.

For the final BOGS 2025 presentation of the day, we have a plenary given by Gordon Inglis - Hopane for the best: developing novel geochemical proxies using bacterial hopanoids.

Now on to the second poster introduction session of BOGS 2025 with short presentations of eight posters. Again, a diverse range of studies being reported.

In the third session of BOGS 2025, we'll have presentations on: isotope analysis of pyrolysates from proteins in paintings, removal of reactive dyes from wastewater and peat core multiproxy investigation of Pleistocene climate. Diverse but linked by the analytical tools being used.

Including fatty acids and isotopes in snow petrel stomach oil deposits. Fantastic!

Followed rapidly by the first poster introduction session of BOGS 2025. Short presentations of eight posters. No let up in the diversity here either!
