Decoding the Gut‐Brain Axis: Multi‐Omics Reveals a Causal Chain Linking Human Genome, Gut Microbiota, Blood Metabolites, and Alertness in the Brain

Med Research, EarlyView.
This multi‐omics study identified genetic loci, gut microbiota, blood metabolites, and gray matter volumes of orbitofrontal cortex and cerebellum that were potentially relevant to alerting in healthy Chinese adults. Subsequent two‐step one‐sample Mendelian randomization further revealed a serial mediation pathway: Bacteroides intestinalis influences ...

Optimizing Ex Vivo MRI and Controlling the Roll of the Specimen Using Container‐ and Brain‐Specific 3D‐Printed Holders

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Positioning and stabilizing a specimen in a container in preparation for ex vivo MRI are challenging. In addition, ex vivo MRI is often performed using preclinical scanners with gradient nonlinearity and nonhomogeneous sensitivity, requiring optimal placement.

The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.
