Summary Compartmentalization of the gastrointestinal (GI) tract of metazoans is critical for health. GI compartments contain specific microbiota, and microbiota dysbiosis is associated with intestinal dysfunction. Dysbiosis develops in aging intestines, yet how this relates to changes in GI compartmentalization remains unclear. The Drosophila GI tract is an accessible model to address this question. Here we show that the stomach-like copper cell region (CCR) in the middle midgut controls distri...

Research in flies and mice supports USC researcher’s theory that the sexes age differently.

We investigated the association between dietary polyamines and risk of CRC incidence and mortality.

The aging processes in brain cells that are thought to underlie cognitive decline may be reversible, according to research published in The Journal of Neuroscience. Researchers believe they have found a way to regenerate the fibers that receive neural impulses.

The risk of dementia is slightly higher in people with minimal exposure to benzodiazepines but not with the highest level of exposure. These results do not support a causal association between benzodiazepine use and dementia.
