title: Travel notes from the equatorial circle.
abstract: Accurate chromosome segregation during mitosis and meiosis is essential for cell viability. Two papers in this issue of Cell (Kitajima et al., 2011; Magidson et al., 2011) describe chromosome movements during cell division with unprecedented accuracy, revealing previously unrecognized features of chromosome spindle alignment and paving the way to quantitative phenotypic and mechanistic analyses of chromosome alignment during prometaphase.
