TIRF imaging of CRISPR-edited human cells shows dynein–dynactin complexes move processively with motility parameters consistent with the presence of multi-dynein assemblies (>one dynein heavy chain dimer per dynactin) in cells.

HIM-5 emerges as a central scaffold that coordinates SPO-11 accessory complexes to control different aspects of meiotic DNA double-strand breaks, ensuring robust crossover formation on autosomes and the X chromosome.
Independent experimental approaches demonstrate changes in TFAM binding to UVC-irradiated DNA, providing a potential mechanism for DNA damage sensing in the mitochondria.
