MIT's AI barcode finds 'zombie cells' without destroying them
Aging research has a measurement problem: the clearest markers of a senescent cell are only readable after the cell is gone. MIT and Harvard have now shown a way around it — and the answer looks like a barcode. A senescent cell stops dividing but refuses to die, and the immune system gets worse at clearing those cells out as we age. When they accumulate they are linked to osteoarthritis, type 2 diabetes, tissue degeneration and cancer — though senescence also does useful work in embryonic devel
