Some cells increase their lifespan through an unprecedented process, according to a study from University College London (UK). In principle, with each cell division, the telomeres at the ends of the chromosomes shorten until the cell dies. But memory T cells have a parade.

Researchers show that memory T cells essential for immunity can receive telomere extensions from other cells, which prolongs their lifespan and therefore our immune memory.
