Gut Microbes may have helped fuel the evolution of large human brains, shaping brain metabolism and gene activity, new ...

Researchers uncover evidence that the gut microbiome and brain connection can influence brain gene expression and neural ...

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that ...

Much of the phenotypic variation that is observed within and between species is the result of differences in gene regulation: specifically when, where and how much the genes are expressed. Given the ...

MicroRNAs, whose discovery was recognized with the 2025 Nobel Prize in Physiology or Medicine, are central regulators of gene ...

In the mice with large-brain primate microbes, the researchers found increased expression of genes associated with energy production and synaptic plasticity, the physical process of learning in the ...

The microorganisms in our gastrointestinal tract-the gut microbiome, can exert a profound influence on the human body, and ...

Two species of worms have retained remarkably similar patterns in the way they switch their genes on and off despite having split from a common ancestor 20 million years ago, a new study finds.

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

Northwestern University research has provided direct experimental evidence that gut microbes influence brain function and ...

A representation of single-cell RNA sequencing data from two species of worms, C. elegans (left) and C. briggsae (right). Each point represents a single cell, arranged such that cells from the same ...
