Researchers are learning how to coax aging blood stem cells in mice to behave more like their younger counterparts, restoring immune function and resilience that typically fade with age. By tuning the ...

When scientists transplanted the gut microbes of aged mice into young "germ-free" mice—raised to have no gut microbes of their own—the recipient mice experienced an increase in inflammation that ...

A recent study published in the journal Nature Aging reports that small extracellular vesicles (sEVs) in plasma from young mice counteract preexisting aging. Study: Small extracellular vesicles from ...
