Researchers develop IRISeq and EnrichSci to map cellular neighborhoods and analyze rare aging cells in the brain simultaneously.

Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier ...

Brain cells, or oligodendrocytes (green), in the hippocampus are marked with the GFP genetic marker in the mouse brain. These cells often deteriorate during aging. Image credit: Gadek et al., Science ...

In a recent study published in the journal Nature, researchers developed spatial aging clocks using single-cell transcriptomics to explore cell-type-specific interactions and their impact on brain ...

Our brains are always adapting to our environments and routines. Host Cristina Quinn talks with Washington Post “Brain Matters” columnist Richard Sima about what a healthy aging brain looks like and ...
