Node-centric expression models (NCEMs): Graph-neural networks reveal communication between cells

Researchers developed a new method to represent cell communication using graph neural networks, which uncovers the effects of tissue niche composition on gene expression. The node-centric expression models (NCEMs) identify cell-cell dependencies and molecular processes underlying cell communication.

Microbiota-derived genotoxic metabolites discovered in patients with inflammatory bowel disease

A new study reveals that gut microbiota from patients with inflammatory bowel disease produce genotoxic metabolites called indolimines, which may contribute to the development of colorectal cancer. The study identified a previously unknown family of DNA-damaging compounds produced by the CRC-associated gut microbe Morganella morganii.

Surface waves help map Mars interior

Scientists have detected seismic surface waves on Mars for the first time, providing new insights into the planet's crust and structure. The study estimates the average properties of the Martian crust between 3 to 18.6 miles below the surface, revealing faster seismic velocities that suggest compositional differences or reduced porosity.

Discovery of endocannabinoid gene mutation leads to identification of new, rare pediatric neurological disease

Researchers identified a new clinical syndrome, Neuro-Ocular DAGLA-related Syndrome (NODRS), in children with termination variants in the diacylglycerol lipase alpha (DAGLA) gene. The study found that enzymatic activity was preserved despite mis-localization of the truncated protein.
