1/11 🔥 New preprint alert 🔥
We wanted to know what plants in the wild really care about. So we asked them 🎤.
Here is what we learned: “Biotic-response networks are an important organizer of the transcriptome in wild Arabidopsis thaliana populations”

The NIH budget was basically the same in 2025 vs. 2024. This massive decline in health research funding was driven by *administrative* choices.

Rapid evolution predicts demographic recovery after extreme drought Populations that are declining as a result of climate change may need to evolve to persist. Although evolutionary rescue has been demonstrated in theory and in the laboratory, its relevance to natural...

Rapid evolution for drought tolerance in Mimulus driven by standing genetic variation and a bit of luck. Another example highlighting the need for large populations and ample genetic diversity.

When Salmonella typhimurium invades cells that line the intestine, it uses a syringe-like type III secretion system to inject dozens of proteins (effectors) into the host cell cytoplasm. This beautiful descriptive study provides the first chronology of the order in which the effectors are injected.

Anyone who is interest in NIH science funding should look through this thread. It's very informative (and disheartening, of course).

New preprint from the Theriot lab and collaborators, which looks at how strain-dependent bile acid transformations by commensal Clostridia attenuate C. difficile virulence and disease without decreasing colonization!

the funniest part of the kobe-bam discourse is the implicit assumption that kobe came by his 81 naturally in the flow of the game rather than the truth, which is that kobe would have killed a teammate in full view of the crowd if any one of them took a shot
