Here’s an awkward red-faced warbler from this morning in New Mexico … to get eyeballs. The band on its leg was provided by the USGS Bird Banding Lab. It’s a thankless task, but they support permitting, band supply, data curation etc for TONS of researchers. They do such good, efficient work and … 🦉🧪

👀This is impressive: Using an autonomous agent based on o3-mini and GPT-4.1, a team from Harvard, MIT & other institutions reproduced and updated an entire issue of Cochrane Reviews in two days… saving 12 person-years of work. The AI reviews captured more papers & were more accurate than humans.

🧪A very good reason why access to Covid vaccines should be preserved. Patients can develop complications following an infection.
My cousin in India died of kidney failure after he got Covid.

It has been a public health failure that the public does not realize how much organ damage COVID infection can cause to things that aren’t your lungs (or throat or nose or taste buds)

223 metagenomes reveal eukaryotes' deep origin outside Heimdallarchaeia within Asgardarchaeota, reshaping the evolutionary timeline dramatically! PMID:40335687, Nature 2025, @Nature doi.org/10.1038/s41586-02… #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪

Deep origin of eukaryotes outside Heimdallarchaeia within Asgardarchaeota | Nature
Research on the morphology, physiology and genomics of Asgard archaea has provided valuable insights into the evolutionary history of eukaryotes1–3. A previous study suggested that eukaryotes are nested within Heimdallarchaeia4, but their exact phylogenetic placement within Asgard archaea remains controversial4,5. This debate complicates understanding of the metabolic features and timescales of early eukaryotic ancestors. Here we generated 223 metagenome-assembled nearly complete genomes of Asgard archaea that have not previously been documented. We identify 16 new lineages at the genus level or higher, which substantially expands the known phylogenetic diversity of Asgard archaea. Through sophisticated phylogenomic analysis of this expanded genomic dataset involving several marker sets we infer that eukaryotes evolved before the diversification of all sampled Heimdallarchaeia, rather than branching with Hodarchaeales within the Heimdallarchaeia. This difference in the placement of euk

Pathological BMP signaling via Grem1 in mice and humans disrupts epithelial-stromal crosstalk, forming ectopic crypts and a wnt-dependent stem cell niche. PMID:40467544, Nat Commun 2025, @NatureComms doi.org/10.1038/s41467-02… #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪

Epithelial GREMLIN1 disrupts intestinal epithelial-mesenchymal crosstalk to induce a wnt-dependent ectopic stem cell niche through stromal remodelling | Nature Communications
In homeostasis, counterbalanced morphogen signalling gradients along the vertical axis of the intestinal mucosa regulate the fate and function of epithelial and stromal cell compartments. Here, we use a disease-positioned mouse and human tissue to explore the consequences of pathological BMP signalling dysregulation on epithelial-mesenchymal interaction. Aberrant pan-epithelial expression of the secreted BMP antagonist Grem1 results in ectopic crypt formation, with lineage tracing demonstrating the presence of Lgr5(−) stem/progenitor cells. Isolated epithelial cell Grem1 expression has no effect on individual cell fate, indicating an intercompartmental impact of mucosal-wide BMP antagonism. Treatment with an anti-Grem1 antibody abrogates the polyposis phenotype, and triangulation of specific pathway inhibitors defines a pathological sequence of events, with Wnt-ligand-dependent ectopic stem cell niches forming through stromal remodelling following BMP disruption. These data support an

🧪Fun fact: The new ACIP has anti vaccine proponents & very likely won’t recommend vaccines to people.
If ACIP doesn’t recommend vaccines, then insurance may not cover them. That potentially impacts access.
This is how these policies impact everyday Americans.
