Happy to see this one out. Lots of fun work identifying bacteriophages in gut metagenomes www.tandfonline.com/doi/full/10....

Deep Cuts to Medical Research Funds Could Hobble University Budgets (Gift Article) Grants from the National Institutes of Health come with additional money for overhead. Proposed funding cuts would leave colleges with large budget gaps.

Venn diagram illustrating microbial diversity of bacteria and archaea captured by isolates, metagenome-assembled genomes (MAGs) from NCBI and IMG, and metagenomes from IMG. A large portion of microbial diversity, labeled as 'Microbial Dark Matter,' represents species not captured by isolates or MAGs. Image modified from https://www.science.org/doi/10.1126/sciadv.adq2166

Genomes assembled from #metagenomes (a.k.a. MAGs) are awesome and have revolutionized our ability to study uncultivated microbes

...BUT: they still don't capture a lot of the 🦠 species that are out there

Top panels: graphs showing increases in spillover events, extinction rates, and temperature anomalies over the last few centuries. Bottom panel: a map of 10 pandemics since the year 1900. Four were linked to agriculture, two to wildlife use, and one to climate change.

🚨😷🧪 NEW: A growing body of evidence shows that pandemics, biodiversity loss, and climate change are part of a broader polycrisis - but there are no simple solutions. A sweeping overview of "Pathogens and planetary change" for the first issue of @natrevbiodiv.bsky.social, out now 🔓 rdcu.be/d6lHl

Interesting work and dataset to investigate the genetic population structure and colonization history of Plasmodium vivax in Latin America, inferring multiple waves of pre/post colonial migration & evolutionary contributions from European and African populations.

horizontal transfers of large sets of genes among key lineages could explain the sporadic distribution of saxitoxin production. A fun project to be a part of and hopefully a valuable addition to an interesting story.

identified the large (53 gene!) biosynthetic gene cluster underlying its production. After screening public genomes for homologous cluster components, we found exceptionally high rates of horizontal transfer of those genes among cyanobacteria and that..

Novel Toxin Biosynthetic Gene Cluster in Harmful Algal Bloom-Causing Heteroscytonema crispum: Insights into the Origins of Paralytic Shellfish Toxins Abstract.

Out now in @genomebiolevol.bsky.social! With colleagues at NBACC and PNNL, we helped answer a long-standing question about how widely-divergent cyanobacteria produce saxitoxin, a major cause of paralytic shellfish poisoning. We assembled a new genome for a producer of saxitoxin and ...
