We’ve posted a new preprint from undergraduate and now post-bac researcher Parsa Zareiesfandabadi. Parsa has interrogated the collapse of the S. pombe spindle that follows laser ablation. Contrary to previous hypotheses, which implicated the nuclear envelope and/or chromosomes in this motion, Parsa found that it’s microtubule dependent and that the molecular motor dynein is involved.
