Durham has been awarded a one-year award that will support analysis and integration of molecular and oceanographical datasets collected as part of the SCOPE-Gradients Program (SCOPE: Simons Collaboration on Ocean Processes and Ecology). Efforts are focused on understanding how chemical and physical features in the North Pacific influence microbial diversity and activity.

We are excited to announce our embarkment into a new project that focuses on metabolite exchange between moss and symbiotic cyanobacteria. Graduate student Rebecca Key will lead the work as part of her dissertation, combining molecular and chemical 'omics measurements to track C, N, and S cycling between moss and associated microbes. The project is supported by JGI’s Community Science Program and led by PI Stuart McDaniel (UF Biology) along with coPIs Bryndan Durham and Todd Rosenstiel (PSU).

Over the past month, we have made a slow and staged return back into the lab. Much of our time has been spent working with colleagues in ICBR to get the new LC-MS system installed and up-and-running through remote instruction and training. Check out the story by UF Research.

Poster reads: "In this lab, we believe: science is real (microscope image), love is love (rainbow anatomical heart), Black lives matter (brown raised fist), feminism is for everyone (female symbol), microbes are cool (single-celled organisms), immigrants are welcome (statue of liberty)." This poster represents our pledge and commitment to continuous allyship, with original image c/o Sammy Katta (https://sammykatta.com/diversity).
New preprint uploaded on bioRxiv from collaborators. Boysen et al., describe day-night cycles in microbial metabolites in the open ocean. Daily oscillations in cellular redox and energetics exert a strong influence on the surface ocean metabolome. Very exciting collaborative work with colleagues in the Simon's Foundation SCOPE Program. Check out the preprint here!

Bruker's timsTOF fleX mass spectrometry system has arrived on UF's campus. The instrument will be operated in ICBR's mass spectrometry core. We are anxiously awaiting instrument setup and training once campus - and our lab - reopen.

Durham & former PhD advisor, Mary Ann Moran at the University of Georgia, have published a review article in Nature Reviews Microbiology entitled "Sulfur metabolites in the pelagic ocean." The co-authors examine how phytoplankton and bacteria produce & transform sulfur metabolites in the ocean, highlighting the critical role that sulfur plays in mediating microbial interactions and ocean ecosystem function.

Durham & colleagues from the University of Washington have published an article in Nature Microbiology, showing the importance of sulfonates in marine microbial interactions. Check out the blog post (link in image) and the manuscript here!
