Leaf side determines the relative importance of dispersal versus host filtering in the phyllosphere microbiome

The paper examines bacterial communities on upper and lower leaf surfaces across 24 plant species, finding that lower leaf surfaces have lower taxonomic richness and are more influenced by host filtering than dispersal.

A metagenomic investigation of spatial and temporal changes in sewage microbiomes across a university campus

This study investigates spatiotemporal changes in sewage microbiomes across a university campus using shotgun metagenomics, revealing dynamic patterns and environmental influences.

Neutrophils promote CXCR3-dependent itch in the development of atopic dermatitis

This study identifies neutrophils as key initiators of itch in atopic dermatitis and shows that CXCR3 antagonism reduces chronic itch.

Mutations that improve the efficiency of a weak-link enzyme are rare compared to adaptive mutations elsewhere in the genome

The paper shows that mutations improving a weak-link enzyme's efficiency are rare compared to other adaptive mutations in the genome during bacterial evolution.

A global survey of mycobacterial diversity in soil

This study surveys global soil mycobacterial diversity, finding high diversity with many undescribed lineages and environmental preferences, but few known pathogens in soil.

Optical Metabolic Imaging of Heterogeneous Drug Response in Pancreatic Cancer Patient Organoids

This study uses optical metabolic imaging to predict pancreatic cancer patient treatment response by analyzing cellular heterogeneity in organoids.

Label-free Method for Classification of T cell Activation

This paper develops a label-free method using NAD(P)H and FAD autofluorescence imaging and machine learning to classify T cell activation states and subtypes with high accuracy.
