The brain may reuse some cells to store many different memories without mixing them up with or erasing older memories, a new study in mice suggests. Led by NYU Langone Health researchers, the study revealed that about one in four memory cells in a brain area called the hippocampus acts as a shared “hub” that links incoming and outgoing signals
Drug delivery and diagnostic imaging often lack specificity, but a new “TRACE” method lets specially‑caged compounds stay inert until a target cell’s enzymes quickly remove the cage, potentially allowing for more precise drug delivery and sharper diagnostic imaging.
