Nov 23, 2023 · The timer bomb on these cells is actually a 'death' receptor, called Fas (or CD95). When activated by the right antibody, it triggers the programmed death of that cell. Scientists at the University of California, Davis (UCD) and Indiana University argue that until recently, Fas has been "undervalued in cancer immunotherapy". An international team of astronomers flipped it again in 2018 and found that a planetary nebula is indeed the most likely solar corpse.
