Effects of malleable kinetochore morphology on measurements of intrakinetochore tension by Fioranna Renda, Valentin Magidson, Irina Tikhonenko, Rebecca Fisher, Christopher Miles, Alex Mogilner, Alexey Khodjakov

“…To assess contributions of these non-elastic changes, we compare behaviour of delta values in human kinetochores with small yet mechanically malleable kinetochores against compound kinetochores in Indian muntjac (IM) cells whose architecture remains constant. Due to the micrometre-scale length of kinetochore plates in IM, their shape and orientation are discernible in conventional light microscopy, which enables precise measurements of IKT independent of contributions from changes in overall architecture of the organelle. …”

An imprint method to produce surface asperities for EHL and RCF experiments by Carl-Magnus Everitt, Bo Alfredsson, Martin Öberg

“…The proposed method enables: • Creation of well-defined micrometre high asperities • Creation of asperities which survived more than 35 million EHL contact cycles • Damage tracing thanks to the possibility to control the damage initiation sites.The technique is based on rolling a hard disc with indents against a soft disc for creating single surface asperities. …”
