The possibility that lithium deficiency is a driver of Alzheimer's disease. Experimental model shows Li depletion impedes amyloid clearance, and repletion in humans could be achieved with low doses

Lithium deficiency and the onset of Alzheimer’s disease - Nature
Lithium has an essential role in the brain and is deficient early in Alzheimer’s disease, which can be recapitulated in mice and treated with a novel lithium salt that restores the physiological level.

Nature research paper: Macrophages recycle phagocytosed bacteria to fuel immunometabolic responses

https://go.nature.com/3XmyOPD
Macrophages recycle phagocytosed bacteria to fuel immunometabolic responses - Nature
Phagocytosed bacteria can serve as an alternative nutrient source for macrophages, influencing their metabolic and immune responses through the recycling of microbial components, with the process regulated by nutrient-sensing mechanisms and bacterial viability.

Legitmately thrilled to share our latest work, in which @fernpizza.bsky.social solved an experimental challenge in plasmid biology as old as the field: measuring how plasmids compete and evolve within individual cells!

Excited to share our MicrobiomeBenchmarkData preprint, addressing compositional data analysis for microbiome DA. This Bioconductor package features 3 datasets with biological ground truths. Spoiler: simple methods like LEfSe, Wilcoxon, RNA-seq methods performed well www.biorxiv.org/content/10.1...
Commonly used compositional data analysis implementations are not advantageous in microbial differential abundance analyses benchmarked against biological ground truth
Previous benchmarking of differential abundance (DA) analysis methods in microbiome studies have employed synthetic data, simulations, and "real data" examples, but to the best of our knowledge, none ...
